Executive summary
1. This report presents the findings and recommendations of ecological surveys carried out at Land east
of Ashingdon Road, Rochford, Essex. The surveys were carried out to inform the planning application
for residential-led development of the site.
2. The study area covered approximately 30 ha and was dominated by arable fields with boundary
habitats including hedgerows, dry ditches, improved and semi-improved grassland, scrub, tall ruderals
and a pond. The application boundary comprises approximately 26 ha within the study area. Rochford
centre and the River Roach lie to the south of the site, with the wider landscape to the south and west
being more developed, and the landscape to the east predominantly set to agricultural use.
3. A preliminary ecological appraisal (PEA) was carried out in March 2019 to identify any ecological
constraints and opportunities in connection with the proposed development. The survey also
identified the need for any additional surveys to determine the presence or likely absence of protected
species and habitats, specifically: hedgerow survey, badger monitoring survey, reptile
presence/absence survey, great crested newt presence/absence survey and population size class
assessment, bat activity and emergence/re-entry surveys.
4. This report provides a summary of the baseline ecological conditions and outlines the importance of
features recorded at the site. Detailed results and maps are provided in Appendices.
5. The report also outlines the impacts, mitigation and enhancement measures to ensure biodiversity is
protected during course of the development and, where possible, enhanced following occupation.
Through implementing the recommended mitigation, it is considered that all significant negative
impacts from the proposed development upon protected and notable habitats and species would be
mitigated in line with relevant wildlife legislation and national and local planning policy related to
biodiversity.

1.0 Introduction and Aims
1.1 Southern Ecological Solutions Ltd. (SES) was commissioned by Bloor Homes Limited to undertake a suite
of ecological surveys and produce an ecological impact assessment report for land east of Ashingdon
Road, Rochford, Essex (Ordnance Survey Grid Reference TQ873916) (the site). A plan showing the
approximate application site boundary and the wider study area is provided in Appendix 1.
1.2 This report has been produced to inform an outline planning application for the demolition of numbers
148 and 150 Ashingdon Road and the development of 665 residential dwellings (C3), a community
facility (D1), open space and associated infrastructure including flood storage and surface water
drainage attenuation, with all matters unreserved for 233 residential dwellings comprising Phase 1 of
the proposals, and all other matters reserved except for Access and Layout. The proposed land use and
access parameter plan is provided in Appendix 1.
1.3 A preliminary ecological appraisal (PEA) was undertaken in March 2019 by SES. This survey aimed to:
• Map the main ecological features within the site and compile a plant species list for each
habitat type;
• Make an initial assessment of the presence or likely absence of species of conservation
concern
• Identify any legal and planning policy constraints relevant to nature conservation which may
affect the development (see Appendix 2);
• Determine any potential further ecological issues;
• Determine the need for further surveys and mitigation; and
• Make recommendations for minimising impacts on biodiversity and providing net gains in
biodiversity where possible in accordance with Chapter 15: Conserving and Enhancing the
Natural Environment, of the National Planning Policy Framework (MHCLG, 2019), and
relevant nature conservation policies within the adopted Rochford Local Development
Framework Core Strategy (2011).
1.4 The following surveys were recommended and subsequently carried out between March and
September 2019:
• Bats (preliminary ground level tree assessment; activity surveys; emergence/re-entry surveys);
• Badger (Meles meles) sett scoping and monitoring surveys;
• Birds (breeding bird surveys);
• Great crested newt (Triturus cristatus) (GCN) (Habitat Suitability Index (HSI) surveys; presence
/ absence surveys; population size class assessment);
• Hedgerow survey;
• Reptile presence / absence surveys, and;
• Notable mammal species assessment.
1.5 This report sets out the results of the above surveys. All features are then evaluated using the evidence
from the desk study, field surveys, previous reports and relevant literature. The proposals for
development are then set out and the impacts on features are assessed. Mitigation options are then
outlined in relation to legal and planning policy obligations and residual effects assessed.

Site Description
1.6 The site is located to the east of Ashingdon Road, Rochford. It is bounded by existing development to
the north, west and south and arable cropland to the east. To the south of the site is the centre of
Rochford, the River Roach and Southend Airport. The wider landscape to the east is predominantly
arable, with the landscape to the west and south being more developed.
1.7 The application site is approximately 26ha in extent and is predominantly set to agricultural use, forming
part of Doggett’s Farm. The site comprises two adjacent fields, separated by a partly defunct hedgerow
and ditch running northwest to southeast through the site. The easternmost section of the field to the
north is not included within the application site boundary, though forms part of the total study area,
comprising approximately 30ha, for the ecological assessments reported herein.

2.0 Methods
2.1 The approach taken follows guidance and methods as prescribed by the Chartered Institute for Ecology
and Environmental Management (CIEEM), specifically the Guidelines for Ecological Appraisal 2nd edition
(2017) and the Guidelines for Ecological Impact Assessment (2018). Following these methods, a baseline
of rare and/or noted ecological receptors (species and habitats) was established and valued. Predicted
significant impacts upon these receptors have been identified and constraints and opportunities
identified. This step-wise assessment process has informed likely mitigation and enhancement
measures. Phase 2 ecological surveys have been implemented to fully inform the predicted impacts of
the scheme in accordance with the National Planning Policy Framework (NPPF) (MHCLG, 2019), local
planning policy and relevant wildlife legislation.
Desk Study
2.2 SES commissioned a data search for records of protected and notable species from Essex Field Club (EFC)
in March 2019. The data search encompassed the study area, and up to 2km from the boundary. This
data was received on 19 March 2019.
2.3 Hazel dormouse Muscardinus avellanarius records were also sought from the National Biodiversity
Network (NBN) Atlas www.nbnatlas.org, which holds data from the People’s Trust for Endangered
Species (PTES). As dormouse are particularly under-recorded, the data search for this species
encompassed an area of up to 10km from the site boundary.
2.4 A web-based search for statutory designated sites via the Multi Agency Geographic Information for the
Countryside (MAGIC) spatial data resource www.magic.gov.uk was undertaken on 24 September 2019
for the following designations: European (up to 22km from the site boundary, as per the maximal Zone
of Influence (ZoI) for Essex coastal internationally designated sites, see 2.5); and national (5km from the
site boundary).
2.5 The Essex Coast Recreational disturbance Avoidance and Mitigation Strategy (RAMS) Habitats
Regulations Assessment Strategy document for 2018-2038 (Place Services, 2019) was referred to in
order to determine the Zone of Influence (ZoI) for coastal European Designated sites and hence the
requirement for off-site mitigation (Table 1).

SPA = Special Protection Area; SSSI = Site of Special Scientific Interest; SAC = Special Conservation Area
2.6 SES also requested details of non-statutory designated sites within 2km of the site boundary from Essex
Wildlife Trust (EWT). This data was received on 25 March 2019.
2.7 Maps of the area of assessment and wider area, using the MAGIC online spatial data resource and aerial
photographs on Google Earth (Google Inc., 2011), were examined to determine the possible habitats
present on, and adjacent to the area of assessment, and their context in the surrounding landscape,
searching in particular for waterbodies, watercourses and other landscape features that may be of
ecological significance to protected species, notably great crested newt and mobile species such as bats
and birds.
2.8 A series of previous ecological surveys of the site were carried out by Lockhart Garett on behalf of Aber
Ltd. in 2016. The 2017 reports for these surveys were reviewed in order to support the current
assessment:
• Phase 1 Habitat Survey Report (Lockhart Garratt ref: 16-0341, 2016)
• Badger Activity Survey Report (Lockhart Garratt reference 16-1967, 2016)
• Bat Activity Survey Report (Lockhart Garratt ref: 16-1855, 2016)
• Great Crested Newt Survey Report (Lockhart Garratt ref: 16-0342, 2016)
• Reptile Survey Report (Lockhart Garratt ref: 16-1853, 2016)
Phase 1 Habitat Survey
2.9 A previous Phase 1 Habitat Survey of the site was carried out in 2016 (Lockhart Garett, July 2017),
however with three years having elapsed since this survey, the information was considered out of date.
A new extended Phase 1 Habitat Survey of the site was therefore carried out on 22 March 2019 to
update the previous survey information. The survey was carried out by suitably qualified ecologist Sarah
Wiltshire BSc (Hons) MSc in fair weather conditions.
2.10 Phase 1 Habitat Survey is a standard technique for obtaining baseline ecological information for areas
of land, including proposed development sites. Phase 1 Habitat Survey methods are set out in the
Handbook for Phase 1 Habitat Survey (Joint Nature Conservation Committee, 2010). Habitat mapping
was undertaken using the standard classification to indicate habitat types. Features of ecological
interest and value were highlighted using target notes.
2.11 The dominant and readily identifiable higher plant species identified in each of the various habitat
parcels were recorded and their abundances assessed on the DAFOR scale:
• D - Dominant
• A - Abundant
• F - Frequent
5
• O - Occasional
• R - Rare
2.12 These scores represent the abundance within the defined area only and do not reflect national or
regional abundances. Plant species nomenclature follows Stace (2010).
Hedgerow Survey
2.13 All hedgerows within and surrounding the site were assessed by Sven Wair of SES on 21 May 2019, to
determine whether they qualify as ‘Important Hedgerows’ under The Hedgerow Regulations (1997).
Detailed survey methods are provided in Appendix 3.
Badgers Preliminary Assessment
2.14 An initial assessment was undertaken during the extended Phase 1 survey, to identify areas that might
be used by badger Meles meles for foraging, commuting and sett creation, and to look for signs of
badgers such as paths, hairs, latrines and setts on site.
Sett Monitoring Survey
2.15 A previous badger survey was carried in 2016 (Lockhart Garett, July 2017); this confirmed the presence
of badger setts on site. With three years having elapsed since the previous survey, this information was
considered out of date. Therefore, a new sett monitoring survey was undertaken over six visits between
29 April and 28 May 2019 by Sarah Wiltshire BSc (Hons) MSc to update the previous assessment. Surveys
were undertaken in accordance with best practice guidelines (Harris et al. 1989; Scottish Badgers, 2018).
Detailed methods are provided in Appendix 3.
Bats Preliminary Assessment
2.16 The site was initially assessed for its suitability to support roosting, foraging and commuting bats during
the extended Phase 1 Survey.
2.17 A further preliminary inspection of two bungalows to be demolished under the development proposals
(148-150 Ashingdon Road) and one oak tree proposed to be felled to facilitate access (located on
Ashingdon Road adjacent to Holt Farm School at OS grid reference TQ 87030 91445) was carried out on
26 July 2019 by Sarah Wiltshire BSc (Hons) MSc and Jim Silverstone of SES.
2.18 All existing habitats were assessed for suitability for bats using guidelines issued by the Bat Conservation
Trust (Collins, 2016). Detailed methodology is provided in Appendix 3.
Internal Building Inspection
2.19 An internal inspection of the interior loft spaces of two bungalows to be demolished under the
development proposals was carried out by Sarah Wiltshire BSc (Hons) MSc and Jim Silverstone of SES
on 26 July 2019.
6
2.20 The loft spaces were searched for evidence of roosting bats using high powered torches. Evidence of
bat occupation sought included the physical presence of bats, droppings, urine staining and mammalian
oil staining. The inspection was carried out in accordance with guidelines issued by the Bat Conservation
Trust (Collins, 2016). Detailed methodology is provided in Appendix 3.
Emergence/re-entry Surveys
2.21 The two existing bungalows to be demolished under the development proposals were identified as
having a ‘low’ suitability for roosting bats and hence further survey was recommended. In accordance
with current guidance for low suitability structures, survey effort comprised one dusk emergence
survey, carried out on 15 August 2019. Detailed methodology is provided in Appendix 3.
Activity Surveys
2.22 The site was assessed as having low suitability for foraging and commuting bats, therefore further
activity surveys including three activity transects and three accompanying five night static bat detector
deployments (two locations per transect) were carried out between May to September 2019. A previous
series of surveys was carried out in 2016 (Lockhart Garett, July 2017), however with three years having
elapsed, this information was considered out of date. In addition, the previous surveys did not obtain
coverage across the bat active season (Spring, Summer, Autumn). Therefore, new surveys were
undertaken in accordance with best practice guidelines (Collins, 2016). Detailed methods are provided
in Appendix 3.
Birds Preliminary Assessment
2.23 An initial assessment was undertaken during the extended Phase 1 survey of the site’s potential to
support breeding birds. Suitable habitat generally includes scrub, trees and ruderal vegetation but can
also include buildings, open grassland and piles of debris. The site was also assessed at this time for its
potential to support significant wintering and/or migratory bird populations.
Breeding Bird Survey
2.24 A breeding bird survey was then subsequently undertaken using a cut-down version of the standard
Common Bird Census (CBC) methods, devised by the British Trust for Ornithology (BTO) (Marchant,
1983; Bibby et al.,1992). This comprised three visits between April to June 2019, undertaken by Darren
Denmead BSc (Hons). Detailed methods are provided in Appendix 3.
Great Crested Newts Habitat Suitability Index (HSI) Survey
2.25 A survey to determine the suitability of accessible ponds within 500m of the study area for great crested
newt Triturus cristatus was undertaken on 22 March 2019 by Sarah Wiltshire BSc (Hons) MSc, in
accordance with best practice guidelines (Oldham et al. 2000). Detailed methods are provided in
Appendix 3.
7
Terrestrial Habitat Assessment
2.26 Terrestrial habitats on site were assessed for their suitability for great crested newt during the extended
Phase 1 survey. Suitable terrestrial habitat generally includes rough grassland and woodland where they
can forage and hibernate, with good links to the ponds where they breed.
Presence / Absence Pond Surveys
2.27 Surveys were undertaken between mid-March and mid-June 2019 to determine the presence or likely
absence of GCN in accessible ponds within 500m of the study area.
2.28 Presence / absence pond surveys were previously carried in 2016 and did not detect the presence of
great crested newts in any ponds surveyed (Lockhart Garett, July 2017). However, with three years
having elapsed since, this information was considered out of date. In addition, some of the closest and
most suitable ponds within the nearby Doggetts Local Wildlife Site (LoWS) were not accessed for the
previous surveys. Therefore a new set of surveys were undertaken in accordance with best practice
guidelines (Langton et al. 2001). Detailed methods are provided in Appendix 3.
Population Size Class Estimation
2.29 Surveys were undertaken between mid-March and mid-June 2019 to determine the population size
class of GCN in ponds where GCN were recorded during presence / absence surveys. Surveys were
undertaken in accordance with best practice guidelines (Langton et al. 2001). Detailed methods are
provided in Appendix 3.
Hazel Dormouse
2.30 Habitats were assessed for their general suitability for hazel dormouse Muscardinus avellanarius during
the extended Phase 1 survey. This species generally uses areas of dense woody vegetation and are more
likely to be found where there is a wide diversity of woody species contributing to a three-dimensional
habitat structure, a number of food sources, plants suitable as nest-building materials and good habitat
connectivity.
Invertebrates
2.31 The site was assessed for its potential to support rare or notable invertebrate species as part of the
extended Phase 1 survey. Factors considered included the presence of uncommon habitats, particular
food plant species, presence of deadwood, and the complexity and density of micro-habitats available.
Otter and Water Vole
2.32 The site was assessed for its potential to support otter Lutra lutra and water vole Arvicola amphibious
during the extended Phase 1 Survey. Otters have been recorded exploiting virtually all types of
waterbodies and waterways in the UK and are found on still waters (canals, lakes, ponds) as well as
rivers and streams of all sizes. Water voles will inhabit most open water and wetland habitats including
streams, canals, wet ditches and ponds.
8
Reptiles Preliminary Assessment
2.33 The site was initially assessed during the extended Phase 1 Survey for its suitability for the four
widespread reptile species; common lizard Zootoca vivipara, slow-worm Anguis fragilis, grass snake
Natrix natrix and adder Vipera berus. Specific habitat requirements vary between species. Common
lizard favour rough grassland, however they can be found in a variety of habitats ranging from woodland
glades to walls and pastures. Slow-worms use similar habitats to common lizards and are often found in
gardens and derelict land. Grass snake have similar habitat requirements to common lizards but have a
greater reliance on ponds and wetlands where they hunt amphibians. Adders occupy areas of rough,
open countryside and are often associated with woodland edge habitats.
Presence / Likely Absence Survey
2.34 A previous reptile survey was carried out on site in 2016 (Lockhart Garett, July 2017); this confirmed the
presence of reptiles on site. With three years having elapsed since the previous survey, this information
was considered out of date. Therefore, a new seven-visit presence/likely absence survey was carried
out by Leigh-Ann Barren of SES to update this assessment. The survey was carried out in accordance
with published guidelines (Froglife, 1999; Gent & Gibson, 2003; HGBI, 1998). Detailed survey methods,
including dates and information regarding weather, are provided in Appendix 3.
Other Notable Species
2.35 The site was assessed during the extended Phase 1 Survey for its potential to support Natural
Environment and Rural Communities (NERC) Act 2006 species of principal importance which are likely
to occur in the local area, including hedgehog Erinaceus europaeus, brown hare Lepus europaeus,
harvest mouse Micromys minutus, polecat Mustela putorius and common toad Bufo bufo.
2.36 In combination with the above surveys, incidental sightings of other notable species were also recorded.
Assessment of Nature Conservation Value
2.37 CIEEM guidelines for Ecological Assessment in the United Kingdom (2018) have been utilised to assess
the impacts upon habitats within the zone of influence of the site. CIEEM suggests that it is best to use
the geographical scale (i.e. international, national, regional etc.) at which a feature (i.e. a habitat, species
or other ecological resource) may or may not be important as the appropriate measure of value. As
such, data from the data search, extended Phase 1 Habitat survey and subsequent species-specific
surveys has been reviewed and the likely occurrence of protected and notable species/species groups
assessed. This has allowed predictions of impacts to be made along with recommendations for
mitigation, compensation and enhancement. Further detail on the assessment methods utilised in this
report is provided in Appendix 4.
2.38 The following geographical scale categories are considered appropriate:
• International;
• National (i.e. England);
• Regional (South East);
• County (Essex);
9
• District (Rochford District);
• Local or Parish (Rochford); and
• Within Site or zone of influence only
Constraints Bat Surveys
2.39 The bat surveys were completed with the assistance of bat detectors. Surveys using bat detectors have
an advantage over other methodologies (such as radio tracking or trapping) in that they are ‘non-
intrusive’ and will therefore not have an adverse effect on the conservation status or welfare of bats.
However, all survey techniques for bats are subject to bias and bat detector surveys may under record
species with weak echolocation calls, such as brown long-eared bats. Bats from the Myotis genus can
be difficult to identify to species from call structure alone (Russ, 2012).
2.40 The results of static detector surveys are based on bat activity recorded at the location immediate to
each static detector, and therefore only describe localised activity at the site. However, detectors were
moved around the site each season to sample different areas therefore this constraint is not considered
to be significant.
2.41 During the summer transect survey part of the northern boundary could not be accessed due to the
dense growth of boundary vegetation and the arable crop. Given the low numbers of bats recorded
across the site during this and other surveys, this constraint is not considered significant.
Great Crested Newt Surveys
2.42 Three ponds within 500m of the northern boundary of the site were identified via aerial maps but could
not be accessed for HSI survey to determine their likely suitability for great crested newts. These ponds
were also not included in the presence/absence pond surveys conducted (P1 was accessed for HSI
survey, but not for subsequent pond surveys).
2.43 This is not considered a significant constraint on the survey information obtained as the nearest of these
ponds is approximately 460m from the wider study area via connecting ecological features (woodland,
hedgerows) and 760m from the application site boundary. Studies suggest a routine migratory range of
up to 250m for great crested newts (Cresswell & Whitworth, 2004), though Jehle (2000) determined a
smaller terrestrial radius of 63m within which 95% of summer refuges were located. Therefore, it is
considered unlikely that any great crested newts associated with these ponds would utilise the habitats
on site.
2.44 In addition P11 (on site pond) was subject to only one visit for the pond presence/absence surveys, as
it subsequently dried out preventing further survey. Given that this pond was previously surveyed over
four visits in 2016 (Lockhart Garrett, July 2017) and no great crested newt were found, and taking into
account the ‘below average’ suitability of the pond, it is considered unlikely that this represents a
significant constraint on the survey information.

3.0 Baseline Ecological Conditions
Local Planning Policy
3.1 Part of the site (23.5ha) is allocated for residential development of at least 500 units (including at least
175 affordable units) under Policy SER8 of the Rochford Local Development Framework Allocations Plan
(2014).
3.2 Further details regarding the planning policies which may apply to this site are provided in Appendix 2.
Designated Sites
3.3 Details of designated sites within influencing distance of the proposed development are provided in
Table 2 below.
3.4 The site falls within the ZoI of three Essex coastal European designated sites that are considered to be
of international importance. All three sites form part of the Essex Estuaries SAC and are underpinned
by national SSSI designations. The nearest of these sites at 1.9km southeast is The Crouch and Roach
Estuary SPA & Ramsar.
3.5 One additional SSSI not associated with the above coastal sites was identified within 5km; Hockley
Woods SSSI. This site is considered to be of national importance. The proposed development site does
not fall within the Natural England SSSI Impact Risk Zone that relates to residential development for this
designated site.
3.6 There is one statutory designated Local Nature Reserve (Magnolia Fields LNR) and seven non-statutory
designated LoWS within 2km; these sites are considered to be of local importance. The closest of these
sites is Doggetts Pond LoWS, approximately 100m east of the site.

The River Crouch occupies a shallow valley between two ridges of London Clay, whilst the River Roach is set predominantly between areas of brick earth and loams with patches of sand and gravel. The intertidal zone along the Rivers Crouch and Roach is 'squeezed' between the sea walls along both banks and the river channel. Unlike more extensive estuaries elsewhere in Essex, this leaves a relatively narrow strip of tidal mud which, nonetheless, is used by significant numbers of birds. The site is of importance for wintering waterbirds, especially Dark-bellied Brent Goose Branta b. bernicla.

Foulness SPA lies on the north shore of the Thames Estuary between Southend in the south and the Rivers Roach and Crouch in the north. It is made up of extensive intertidal sand silt flats, saltmarsh, beaches, grazing marshes, rough grass and scrubland. The site is of international importance for six species and national importance for three species of wintering wildfowl, with the islands, creeks and grazing land forming an integral part of the sheltered feeding and roosting sites. The shell banks support nationally important breeding colonies of little terns Sterna albifrons, common terns Sterna hirundo and sandwich terns Thallaseus sandivcensus. Avocets Recurvirostra avosetta also breed on this site in nationally important numbers.
Blackwater Estuary SPA &
Ramsar
Underpinned by Blackwater
Estuary SSSI
10.4km north

The habitats present include saltmarsh, mudflats, shingle and shell banks. The site is designated a SPA for supporting populations of importance of numerous bird species listed under Annex I of the Birds Directive, including breeding little tern Sterna, winter populations of avocet and hen harrier Circus cyaneus, and passage ringer plover Charadrius hiaticula. The assemblage at the site qualifies the SPA as a wetland of international importance.
Essex Estuaries SAC
1.9km southeast
46111
The site is designated for the extensive areas of habitat present that are listed under Annex I of the Habitats Directive. These habitats include estuaries, mudflats and sandflats not covered by seawater at low tide, and Atlantic salt meadows, which are of European importance. The SAC forms the wider habitat matrix within which the Blackwater Estuary SPA/Ramsar and Croach and Roach Estuaries SPA/Ramsar are located.
Hockley Woods SSSI
3km west
92.1
Hockley Woods are a contiguous group of ancient coppice woods incorporating Great Bull wood, Great Hawkwell Wood, Beeches Wood and Parson's Snipe. They lie on the crest and slopes of a ridge of pre-glacial gravels and clay north-west of Southend-on-Sea. They form one of the most extensive areas of ancient woodland in South Essex, the dominant stand types comprising the Sweet chestnut variants of Pedunculate oak-hornbeam - birch-hazel variant and acid Sessile oak-hornbeam. The population of Sessile Oak Quercus petraea is probably the largest in eastern England.

These former gravel pits have developed a good general wildlife interest. The site comprises a large pond with associated beds of bulrush Typha latifolia and common reed Phragmites australis. Patches of scattered and dense hawthorn Crataegus monogyna, willow Salix sp. and bramble Rubus fruticosus agg. are found around the peripheral areas of the site. These attract numerous birds and insect species. Birds of interest include reed Acrocephalus scirpaceus and sedge warblers Acrocephalus schoenobaenus, lesser whitethroat Sylvia curruca and breeding little grebe Tachybaptus ruficollis. Both water vole and great crested newt have been recorded from this site.

NBN Atlas identified 112 records within 10km, the nearest originating from Hockley Woods, 3km west
of the site, and recorded in 2014.
Extended Phase 1 Habitat Survey
3.9 The Phase 1 Habitat plan of the site and adjacent habitats and the plant species recorded in each habitat
type are tabled in Appendix 5. Photographs of habitat features are also provided in Appendix 5.
3.10 There were 11 different Phase 1 Habitat types found within the study area and on the boundaries:
• Amenity grassland;
• Arable;
• Buildings and hardstanding;
• Dense/scattered scrub;
• Dry ditches;
• Hedgerows;
• Improved grassland;
• Semi-improved grassland;
• Scattered trees;
• Standing water and;
• Tall ruderal.
14
Amenity grassland
3.11 To the west of the site were two semi-detached bungalows. The rear gardens associated with these
properties were set to lawn, dominated by perennial rye grass Lolium perenne. The lawns had not been
recently maintained and a tall sward containing interspersed ruderals, in particular common nettle
Urtica dioica, was present at the time of survey. This habitat showed very little floristic diversity and is
common locally, with the northern, western and southern boundaries of the site all abutting residential
gardens. Therefore this habitat is considered of site importance only.
Arable
3.12 Arable was the dominant habitat on site, comprising two crop fields separated by a hedgerow running
northwest to southeast. During the 2019 survey season an oil-seed rape crop Brassica napus was
present. The crop was very dense with few weeds amongst it, evidencing a likely history of spraying.
However, ruderals such as scentless mayweed Tripleurospermum inodorum and common nettle and
scrub (predominantly bramble Rubus fruticosus agg.) frequently intruded and intermixed with the crop
at the margins.
3.13 The field margins to the north, south and west were approximately 2-3m wide and densely vegetated
with a mix of scrub and ruderals. The field margin to the east varied from 2-3m wide up to 10m wide
where a vehicle trackway was present. This boundary contained mixed grasses and ruderals with less
areas of scrub. Finally through the centre of the site and associated with a partially defunct hedgerow
and dry ditch there was an approximately 10m wide strip of improved grassland. In all cases, floristic
diversity of the boundary habitats was very low with just a few common species dominating. There was
no evidence that the boundary habitats were actively managed for wildlife, and hence they were not
considered to qualify as a Habitat of Principle Importance (HoPI) under the NERC Act 2006 (Arable field
margins). However, they nonetheless were considered to have ecological value as connecting habitat
and cover for a variety of fauna likely to use the site. Further details on the species present within these
boundary habitats are provided below.
3.14 Arable cropland is a common habitat locally, with extensive tracts present in the local landscape
particularly to the east of the site. Due to this and the evident intensive nature of current management,
which has driven the low floristic diversity observed in the field boundaries, this habitat is considered of
site importance only.
Buildings and hardstanding
3.15 One building was present to the west of the site. The building comprised two semi-detached bungalows
known as 148-150 Ashingdon Road. The building appeared to date from the post-war era and had a
pitched hip and gable roof, clad in clay tiles, with later flat felt-roofed additions to the rear. The walls
were clad in concrete render. A hardstanding driveway was present to the frontage of both dwellings.
These habitats are considered of negligible ecological importance.
Dense scrub
3.16 Patches of dense and scattered scrub were present along the field boundaries, particularly those
abutting residential gardens to the south, west and north, though none of these patches were notably
extensive. A further patch of scrub was present off-site, adjacent to the southeast corner and covering
a large earth mound. Scrub was dominated by bramble with some blackthorn Prunus spinosa. Due to
15
the limited extent of the scrub patches and dominance of just two common species, this habitat is
considered of site importance only.
Dry ditches
3.17 Two hedgerows on site (H2 and H3) were associated with ditches, which were almost wholly dry at the
time of the initial PEA in March 2019 and remained so throughout the 2019 survey season. The banks
of the ditches were predominantly shaded by the associated hedgerows and so ground flora was absent
throughout most sections. Where more open conditions existed, such as towards the western defunct
section of H3, vegetation comprised mainly dense bramble scrub and common nettle. Due to the limited
flora associated with these ditches they are considered of site importance only.
Hedgerows
3.18 Three hedgerows were present within the study area, with two adjoining/within the application site
boundary (H2 and H3) and one at the eastern boundary of the study area (H1). H2 and H3 comprised
mainly native woody species and in general were dominated by either hawthorn Crataegus monogyna
or blackthorn. Standards were present in H2 and H3, with notable mature oak Quercus robur of
particular interest within H2. Due to the range of native woody species seen in H2 and associated
features (ditch and standard trees), hedgerows on site are considered to be of local importance.
Hedgerows were subject to a detailed survey, see 3.28 for further information.
Improved grassland
3.19 Improved grassland was present as a 10m wide strip at the field boundaries to the east and through the
centre of the site. Perennial ryegrass was dominant with Yorkshire fog Holcus lanatus and annual
meadow grass Poa annua also noted. Interspersed forbs included creeping buttercup Ranunculus repens
and daisy Bellis perennis. While floristic diversity was low evidencing the sites history of improvement,
management of the grassland was low-intensity with a tall sward maintained through the summer
season. This drives an assessment of site level importance for this habitat.
Semi-improved grassland
3.20 To the north of the study area, just beyond the application site boundary was a patch of grassland with
a more semi-improved quality, including cock’s foot Dacytlis glomerata and Yorkshire fog and with a
lower proportion of rye grass. A greater diversity of herbs were noted here, including broad leaved dock
Rumex obtusifoloius bristly ox-tongue Helminthotheca echoides doves-foot cranesbill Geranium mole
and milkweed Euphorbia peplus. The limited extent of this habitat (approximately 0.2ha) and still
relatively low floristic diversity drives an assessment of only site level importance for this habitat.
However, with a tall sward, it is considered this feature has ecological value as cover and foraging habitat
for a variety of fauna likely to utilise the site.
Scattered trees
3.21 Trees were incorporated within the hedgerows; these are discussed in further detail in 3.18 and 3.27
onward. In addition trees were present around a pond to the east (see 3.22) and scattered along the
southern, western and northern boundaries of the site, both within and overhanging the site from
adjacent residential gardens. Species included pendunculate oak, ash, cypress Cupresssus lawsonii, elder
Sambucus nigra and cherry plum Prunus cerasifera. The oak trees, predominantly incorporated within
16
H2, were the most notable specimens due to their maturity. However, trees on site were generally
considered to be representative of those widely found across the local landscape, and no ancient or
veteran trees were recorded. As such trees are considered to be of site importance only.
Standing water
3.22 One waterbody was present at the eastern boundary of the study area. This was a small pond less than
10m x 10m in size, which had a depth of approximately 0.5m at the time of the initial PEA survey in
March 2019 and had fully dried out by 2 May 2019. The pond was vegetated with yellow flag iris Iris
pseudacorus, with bramble scrub and pendunculate oak and ash trees lining the banks. The ponds value
was considered to be limited by high levels of shading and relatively poor water quality, both
contributing to a lack of aquatic vegetation diversity. It is considered that this pond would not meet the
criteria to qualify as HoPI under the NERC Act 2006, as poor water quality and sparse vegetation would
be expected to limit the invertebrate assemblage associated with this feature. Nonetheless it is
considered a valuable resource for the fauna utilising the site and as such is considered to be of local
importance.
Tall ruderal
3.23 Tall ruderals were present in patches amidst scrub along the southern, western and northern boundaries
of the site. Common nettle and goosegrass Galium aparine were strongly dominant throughout. The
low level of floristic diversity and ubiquitous nature of species observed in this habitat drives the
assessment of site level importance for this habitat.
Summary
3.24 The habitats within the study area ranged from those of negligible ecological value (buildings and
hardstanding) to those with higher value (arable boundaries, semi-improved grassland, pond and
hedgerows). A summary is provided in Table 4; habitats at the site are considered to be of importance
up to the local level.

Flora Rare flora
3.25 The flora comprised common and widespread species and was considered to be of importance at the
site level.
Invasive plant species
3.26 A stand of Japanese knotweed Fallopia japonica, a non-native invasive species listed under Schedule 9
of the Wildlife and Countryside Act 1981 (as amended), was recorded within the site on the southern
boundary (see Appendix 5, TN12 for location). Stems were also noted in the adjacent residential garden.
It is illegal to plant or otherwise allow this species to grow in the wild.
Hedgerows
3.27 Of three hedgerows identified in the study area, one (H2) was classified as important under The
Hedgerow Regulations 1997. Hedgerow H3 also comprised 80% or more of at least one woody UK native
species, and therefore is considered to qualify as HoPI under the NERC Act 2006. The hedgerow network
within the site is considered to be of importance at a local level.
3.28 A plan of the hedgerows and sections surveyed is provided in Appendix 6. Descriptions of each hedgerow
and associated features are provided below:
Hedgerow 1
3.29 Hedgerow 1 was 540m in length and approximately 4m in height. It was species poor in nature, with an
average of only two native woody species as defined in Schedule 3 of the Hedgerow Regulations
recorded per 30m section surveyed. It was strongly dominated by cherry plum (not a native woody
species listed under Schedule 3), with occasional elder, ash and hawthorn interspersed.
3.30 No woodland ground flora species as defined in Schedule 2 of the Hedgerow Regulations were observed.
Ground flora comprised of common species including cock’s foot, cow parsley Anthriscus sylvestris,
ragwort Jacobaea vulgaris, lesser burdock Arctium minus, nipple wort Lapsana communis and hedge
mustard Sisymbrium officinale.
3.31 The hedgerow had one qualifying associated feature: less than 10% gaps. The hedgerow also connected
with two other hedgerows, scoring two points for connections, but not meeting the minimum four
points required to qualify for this associated feature.
3.32 With an average of two woody species and one associated feature, this hedgerow is considered not
important under the Wildlife and Landscape criteria of the Hedgerow Regulations 1997.
Hedgerow 2
3.33 Hedgerow 2 was 450m in length and between 4-8m in height. It was species rich in nature, with an
average of five native woody species as defined in Schedule 3 of the Hedgerow Regulations recorded
per 30m section surveyed. Blackthorn and hawthorn were the most dominant hedgerow species, with
18
pendunculate oak and ash standards, elder, field maple Acer campestre, dogwood Cornus sanguinea
and hazel Corylus avellana at intervals throughout.
3.34 No woodland ground flora species as defined in Schedule 2 of the Hedgerow Regulations were observed.
Ground flora comprised of common species including perennial rye grass, cow parsley, common mallow
Malva sylvestris, red campion Silene dioica and creeping thistle Cirsium arvense.
3.35 The hedgerow had four qualifying associated features: ditch along at least half of length, at least one
standard per 50m, less than 10% gaps, and connections to other ecological features (scoring six points
in total), including a pond (two points), a patch of off-site woodland (two points) and two other
hedgerows (two points).
3.36 With an average of five woody species and four qualifying associated features, this hedgerow is
considered important under the Wildlife and Landscape criteria of the Hedgerow Regulations 1997.
Hedgerow 3
3.37 Hedgerow 3 was 480m in length (inclusive of significant gaps) and approximately 4m in height. It was
species poor in nature, with an average of four native woody species as defined in Schedule 3 of the
Hedgerow Regulations recorded per 30m section surveyed. Blackthorn and hawthorn were the most
dominant hedgerow species, with goat willow Salix caprea dog rose Rosa canina and occasional
pendunculate oak also recorded. This hedgerow was defunct to the west with significant gaps along it’s
total length.
3.38 No woodland ground flora species as defined in Schedule 2 of the Hedgerow Regulations were observed.
Ground flora comprised of common species including perennial rye grass, cow parsley, meadow
buttercup Ranunculus acris, creeping thistle, and goosegrass.
3.39 The hedgerow had two qualifying associated features: ditch along at least half of length, and at least
one standard per 50m. The hedgerow also scored one point of the four required for connections to
other ecological features (connection to one other hedgerow).
3.40 With an average of four woody species and two qualifying associated features, this hedgerow is
considered not important under the Wildlife and Landscape criteria of the Hedgerow Regulations 1997.
Badgers Preliminary Assessment
3.41 Suitable foraging, commuting and sett building habitat was identified on site during the extended Phase
1 survey. This took the form of field boundary scrub and ruderal habitats (foraging and connecting
habitat) and ditches associated with the hedgerows (sett building habitat).
3.42 Multiple signs of badger activity were observed throughout the study area, including well-worn paths,
snuffle holes, latrines and setts. Due to the confidential nature of data relating to badgers, further details
on the locations of badger signs and setts are provided in Confidential Appendix 7.
19
Sett Monitoring Survey
3.43 A previous badger survey was carried in 2016 (Lockhart Garett, July 2017); this confirmed the presence
of one active main sett and two subsidiary setts on site. The current sett monitoring survey, undertaken
to update the previous assessment, confirmed that all three of the previously recorded setts remain in
active use by badgers. In addition, two new active subsidiary setts, one new active outlier sett and one
further disused outlier sett were identified. Results are summarised below:
Table 5. Summary of badger survey results.

3.44 Due to the confidential nature of data relating to badgers, detailed results of the badger monitoring
surveys, including maps of sett locations, are provided in Confidential Appendix 7.
Importance
3.45 Badgers are protected under the Protection of Badgers Act 1992. Due to the high levels of badger
activity and multiple active setts present, the site is considered to be of local importance for badgers.
Bats
Preliminary Assessment & Internal Building Inspection
Roosting Bats: Trees
3.46 Previous surveys carried out in 2016 (Lockhart Garett, July 2017) had identified several mature oaks to
the north of the site containing suitable features for roosting bats; however this area is no longer
included in the application site or study area boundary. The great majority of trees on and bordering
the site were observed to be semi to early mature and lacked decay and damage features that could
provide suitable bat roosting habitat. Two trees were identified within the study area that were
considered to have a low to high suitability for roosting bats. Details are provided in Table 6 below.

3.47 A plan showing the location of suitable trees and photographs of suitable roost features are provided in
Appendix 8.
3.48 Trees considered to have negligible suitability for roosting bats are not included in the plan. This includes
the tree located on Ashingdon Road adjacent to Holt Farm School at OS grid reference TQ 87030 91445
(Referenced T1 in the AIA), which was determined to be of negligible suitability for roosting bats.
Roosting Bats: Buildings
3.49 During the external inspection of the bungalows at 148-150 Ashingdon Road, potential accesses for bats
were noted around the base of the chimney to the west and east, and under occasional gappy and
missing tiles within the roof structure.
3.50 However, internal inspection of the loft space of 148 revealed the interior of the roof to be entirely
unlined, ruling out the possibility for bats to roost underneath the tiles. Inspection of the loft in 150
revealed the interior to have been insulated with blocks of polystyrene; the area underneath this was
not viewed to determine if any lining was present in this section, however it was considered most likely
that the polystyrene blocks had been installed by a previous occupant in a DIY attempt to overcome
draft / water ingress issues resulting from the lack of lining, as the work did not appear to have been
completed to a professional standard using the correct materials.
3.51 The roof timbers in both lofts were observed to be in a generally good condition, with no crevices at
joints that could potentially provide roosting opportunities. Therefore, it was considered that
opportunities within the lofts were limited to roosting in the open on the beams themselves. It was
further expected that due to lack of lining, any evidence of bats using the loft space of 148 (e.g.
droppings, bats themselves) should be readily observable from the loft interior.
3.52 Two bat droppings were found during the search, one per loft interior. However, both were considered
to be extremely old, crumbling readily to dust. No further evidence of bats was found and it is considered
given the age of the droppings that there is nothing to indicate that the building is an active or recent
roost.
Table 7. Results of the preliminary bat roost inspection of buildings.
Building 148-150 Ashingdon Road
Description
Single storey semi-detached bungalows, dating from post-war era. Pitched hipped roof with two gable sections to east, clad in clay tiles, with later flat felt roofed additions to west. Mixed timber and uPVC fascias, in good order and well sealed. Concrete rendered walls and modern uPVC windows, well fitted to frames. No internal roof lining (148), or clad in polystyrene sheets (150).
Bat roost potential
Missing roof tiles beneath ridge of gable section on 148. Gap on eastern elevation beneath chimney due to hole in concrete flashings. Gap on western elevation beneath chimney due to lifted tile at base. Occasional missing or slipped tiles, and gaps underneath tiles, throughout roof; however no potential to roost between tiles & lining, as no lining present.
Evidence of bats Two historic bat droppings with appearance of pipistrelle species, one per loft. Very old and crumbling to dust. No evidence of recent or current roosting activity.
Suitability Low
21
3.53 In summary, while the roof structure of the building was noted to contain gaps providing potential
access opportunities for bats, internal roosting opportunities were considered to be very limited. Given
this, it was considered highly unlikely that a roost of high conservation status was present. Furthermore,
had e.g. a maternity roost been present, it was expected that evidence of this would have been readily
observable due to the unlined roof interior. Considering the results of the inspection as a whole, it was
considered most likely that the two historic droppings found originated from individual opportunistic
bats, who had at some point found their way into the loft, but finding little opportunity to roost, had
not returned. It was considered that a currently active roost was not present, and that overall the
building had only a low suitability for roosting bats.
Foraging and Commuting Bats
3.54 The boundary habitats on site (hedgerows, scrub, ruderals, scattered trees and pond) were considered
to offer opportunities for foraging and commuting bats. However, the centre and great majority of the
site was considered to offer very limited opportunity, as an arable monoculture subject to conventional
management that is likely to be unfavourable for bats invertebrate prey. In addition, more favourable
bat foraging habitats were noted off-site to the east, with the Doggetts Pond LoWs providing more
extensive scrub and woodland habitats as well as larger waterbodies. It was therefore considered
unlikely that the habitats on site would represent core foraging habitat for the local bat population.
3.55 It was noted that the hedgerows on site do not directly connect to the favourable bat foraging habitats
present at Doggetts Pond LoWs. However, H3 was nonetheless considered to provide some linkage
between residential properties to the west of the application site (which could potentially contain
roosts) and this site. The value of this feature as connecting habitat was considered to be limited by the
defunct, gappy nature of the hedge towards its western end.
3.56 Data from previous bat surveys carried out in 2016 (Lockhart Garett, July 2017) was also referred to in
order to inform the preliminary assessment. While previous surveys were constrained by a lack of data
collection during the spring and mid-summer periods, results from these surveys nonetheless indicated
that the foraging and commuting habitats on site were used by low numbers of individuals of common
bat species that are more typically associated with urban edge habitats, such as common Pipistrellus
pipistrellus and soprano pipistrelle Pipistrellus pygmaeus.
3.57 Taking into account all these factors, the site was valued as being of low suitability for foraging and
commuting bats.
Emergence/re-entry Surveys
3.58 As the bungalows to be demolished under the development proposals at 148-150 Ashingdon Road were
identified as having a ‘low’ suitability for roosting bats one further dusk emergence survey was carried
out. No bats were observed emerging from the building and bat activity was very low throughout the
survey despite good weather conditions. Only eight bat passes were recorded by the three surveyors
over the course of the survey, and it was considered likely that these originated from four individual
bats. All recordings were of common or soprano pipistrelle. Detailed results and weather conditions are
provided in Appendix 8.
22
3.59 The tree identified as being of high suitability for roosting bats (T1) was not subject to further
emergence/re-entry survey as this was situated outside of the application site boundary and will not be
impacted under the development proposals.
Activity Surveys Transects
3.60 A total of three species were recorded during transect surveys; common pipistrelle, soprano pipistrelle
and noctule (Nyctalus noctula). Activity levels were low, with intermittent passes being recorded from
a maximum of 3 individuals at any one time. Highest levels of activity were recorded along the northern,
western and southern boundaries, where bats foraged along the field edge and adjoining residential
gardens. Detailed results are provided in Appendix 8.

Static Deployments
3.61 Analysis of data from static deployments increased the list of bat species associated with the site to
eight. Additional species recorded (in addition to those mentioned above) included Nathusius pipistrelle
Pipistrellus nathusii, Leisler’s bat Nyctalus leisleri, serotine Eptesicus serotinus, brown long-eared bat
Plecotus auritus, and an undetermined myotis species. The great majority of activity was from common
and soprano pipistrelle, with only very low numbers of individual passes from other species. Overall
activity levels were also low; an average of 108 total bat passes per night were recorded, combining
data for the two locations sampled each season.

Importance
Roosting Bats
3.62 As no bats were observed to emerge from 148-150 Ashingdon Road during the dusk survey and roosting
opportunities within this structure are considered to be very limited, buildings on site are considered to
be of negligible importance for roosting bats.
3.63 Given the very low number of trees observed on site with suitability for roosting bats (two), it is
considered that tree roosting opportunities are likely to be higher outside of the site within the broader
local landscape. Trees on site are therefore considered to be of site importance only for roosting bats.
A tree roost of high conservation significance is considered unlikely to be present given the common
species and low numbers of bat passes recorded during transect surveys, and the limited suitability of
the foraging and commuting habitat on site.
Foraging and Commuting Bats
3.64 Bat species found on site are considered to be ‘common’ (common pipistrelle; soprano pipistrelle) and
‘rarer’ (Nathusius’ pipistrelle; noctule; Leisler’s, serotine and Myotis sp.). Information on the distribution
of the bat species in Essex is provided in Table 10.
Table 10. Distribution of bats in Essex (Dobson & Tansley, 2014; EBG, 2018)
Bat species Status in Essex
Common pipistrelle Widespread, occasionally common. One of the two species most likely to be
encountered and regularly seen at dusk around gardens.
Soprano pipistrelle Widespread, occasionally common. One of the two species most likely to be
encountered and regularly seen at dusk around gardens.
Nathusius' pipistrelle A migratory species that may breed in small numbers, but maternity roosts are yet
to be found within the county. Considered to be rare but possibly over-looked.
Noctule Widespread, but relatively scarce.
Leisler’s bat Widespread, but scarce.
Serotine Widespread, but scarce. Thought to have declined greatly in the last thirty years.
Myotis sp.
Genus including six British species:
Daubenton’s Myotis daubentonii - Widespread, relatively frequent near still water.
Natterer’s Myotis nattereri - Widespread, relatively scarce.
Whiskered Myotis mystacinus - One record, assumed to be very rare in Essex.
Brandt’s Myotis brandtii - Not recorded in Essex.
Alcathoe Myotis alcathoe - Not recorded in Essex.
Bechstein’s Myotis bechstenii - Not recorded in Essex.
3.65 Common pipistrelle were the most commonly recorded bats during surveys. However, levels of activity
even for this species were low; on average only 19 passes were recorded per transect, and 81 passes
per static sampling night, combining data for two sampling locations.
24
3.66 Given the low levels of overall bat activity observed and also the very low numbers of passes recorded
for ‘rarer’ species, the site is considered to be of only site level importance for foraging and commuting
bats.
Birds
Preliminary Assessment
3.67 It was considered that the arable fields could provide suitable breeding habitat for ground nesting birds
such as the red-listed skylark, and during the Phase 1 survey, several skylark were observed in territorial
song flight over the site. The hedgerows, trees and scrub at the boundaries were also considered to
provide suitable nesting habitat for a bird assemblage that could potentially include red and amber list
farmland species such as yellowhammer, linnet and corn bunting, all of which have been recorded
within 2km of the site.
Breeding Bird Survey
3.68 The breeding bird surveys recorded a total of 27 species of which 22 were breeding in accordance with
the BTO breeding status code. The remaining five were not considered to be breeding within the site
and were either foraging over the site or flying over.
3.69 There were five red-listed Birds of Conservation Concern (BoCC) in accordance with the most recent
conservation assessment (Eaton et al., 2015) of which all five were breeding. These included farmland
species such as: skylark, linnet and starling. Starling was the most numerous bird and was recorded in
moderate numbers throughout the farmland on the site and adjacent residential. Hedgerows supported
starling and linnet, arable farmland supported skylark and the margins supported pheasant. Arable, the
dominant habitat on site, provided foraging and nesting habitat for skylark. However, only one skylark
territory was recorded across the site.
3.70 There were five amber-listed BoCC, of which one was considered a breeding species; dunnock Prunella
modularis. There were no Schedule 1 species recorded on site. Results are summarised in Table 11
below. Full results and territory maps are provided in Appendix 9.

Importance
3.71 The bird community size is a function of the size of the site and also the lack of diversity of habitats.
There were 27 species recorded of which 22 were considered breeding. The farmland bird community
was not especially rich and there were surprising gaps such as a lack of finches utilising the farmland
habitats.
25
3.72 The surveys did not record any notable farmland birds such as turtle dove Streptopelia turtur, redpoll
Carduelis cabaret or barn owl Tyto alba. The species list reflected the common habitats within the site
and surrounding residential areas.
3.73 The breeding bird community is hence considered as being of local value based on the criteria of Fuller
(1980).

Great Crested Newt Habitat Suitability Index (HSI) Survey
3.74 A total of 13 ponds were identified in the vicinity of the study area. Eleven of these were identified from
aerial maps, with a further two within the Doggetts Pond LoWS located via a walkover of the site (P12
and P13) (see Appendix 10a for location plan). The nearest pond (P11) was located on the eastern
boundary of the applicate site. The furthest pond, P8, was located approximately 580m from the study
area boundary, and as such was not subject to further survey.
3.75 Of 12 ponds within 500m, nine were accessed for HSI survey. Of these, six were assessed as poor
suitability, two below average suitability, and one (P12) as having average suitability to support great
crested newt. Poor suitability was typically driven by high impacts of fish and waterfowl. Results are
summarised below, with full results available in Appendix 10:
Table 13. Summary of HSI Scores.
Pond No. HSI Suitability Predicted Probability of GCN Presence
1 0.47 Poor 0.03
5 0.29 Poor 0.03
6 0.42 Poor 0.03
7 0.45 Poor 0.03
9 0.32 Poor 0.03
10 0.32 Poor 0.03
11 0.58 Below Average 0.20
12 0.69 Average 0.55
13 0.6 Below Average 0.20
3.76 The below average score for P11, the on-site pond, was driven primarily by poor water quality and the
small area of the pond. P12, the only average suitability pond, is located within the Doggett’s Pond
LoWs, approximately 230m from the application site (straight line distance), rising to approximately
270m following field boundary habitats.
26
Terrestrial Habitat Assessment
3.77 The boundary habitats on site (hedgerows, scrub, ruderals) were considered suitable terrestrial habitat
for great crested newt, providing cover and a connecting feature through the landscape. However, their
suitability was considered to be limited by the lack of a direct hedgerow connection between the site,
P12 (the most likely suitable breeding pond), and the more extensive suitable terrestrial habitat
surrounding P12 (woodland and scrub) at the Doggetts Pond LoWS.
Presence / Absence Pond Surveys
3.78 Previous presence / absence pond surveys were carried out in 2016 (Lockhart Garett, July 2017), and no
great crested newts were recorded in any of the ponds surveyed at this time. However, the ponds at
Doggetts LoWS were not accessed for the previous surveys. As P12 and P13 at this site were assessed
as being some of the more suitable ponds for great crested newt, further surveys were recommended
to broaden and update the survey data.
3.79 Presence/absence surveys were therefore undertaken at eight ponds within 500m of the site that were
accessible for survey (P1-P4 to the north of the site were not accessed). This included four waterbodies
at Doggetts Pond LoWs. P11, the on-site pond, was surveyed during the first visit only. The pond then
fully dried out before the second visit, precluding any further survey.
3.80 Great crested newt were confirmed to be present and breeding in only one pond (P12). P13 was
confirmed to support breeding smooth newt Lissotriton vulgaris, and common toad Bufo bufo was
recorded at P5. Detailed results are provided in Appendix 10.

Population Size Class Estimation
3.81 With a peak count of 3 great crested newt adults recorded in P12 and no evidence of great crested newt
presence noted at any other ponds surveyed in the local network, the metapopulation class size is ‘small’
according to the established method.
27
Importance
3.82 It is considered highly unlikely that great crested newt use the application site pond (P11) for breeding,
as no evidence of the presence of this species was detected during either the previous or current
surveys, and the pond also scored ‘below average’ for suitability on the HSI. While this pond was only
surveyed once during 2019 before drying out, it was subject to four visits during 2016 when great
crested newt were found to be likely absent. There is nothing to suggest that conditions within or
surrounding the site have changed in the intervening time period.
3.83 A small population of great crested newt was confirmed to be present locally, but was recorded in only
one pond (P12), located approximately 230m from the application site (straight line distance), or 270m
following suitable terrestrial connecting habitat (field boundaries vegetated with scrub and ruderals).
There are areas of terrestrial habitat suitable for this species at the boundaries of the application site
(scrub, ruderals, hedgerows), however on the balance of probabilities it is considered unlikely that these
would be utilised by the small population of great crested newt associated with P12. This is partly due
to distance (270m via connecting ecological features), as studies suggest a routine migratory range of
up to 250m for great crested newts (Cresswell & Whitworth, 2004), and Jehle (2000) determined a
smaller terrestrial radius of 63m within which 95% of summer refuges were located. In addition, ample
highly suitable terrestrial habitat is present in the immediate surroundings of P12 (scrub and woodland),
limiting the need for great crested newts to travel beyond the immediate surroundings of the breeding
pond in their terrestrial phase.
3.84 As such the application site is considered of likely negligible importance to the local great crested newt
population. Nonetheless precautionary measures are advised to account for residual risk, given the high
level of protection afforded to this species. Mitigation proposed for reptiles in Section 4 will deliver this,
and in the unlikely event great crested newt are found on site during works, works will stop immediately,
and an appropriate mitigation license will be sought. Great crested newt are not considered further in
this report.
Hazel Dormouse
3.85 H2 was considered to provide suitable habitat for dormouse, with a range of native woody species and
a thick, tall, bushy structure as favoured by this species. However it was considered unlikely that this
hedgerow would be utilised by this species, as the only existing records within 10km are from woodlands
that lie to the west of the site beyond features that pose a likely major barrier to dormouse movement
through the landscape (railway lines, roads and residential development). Dormice live at low densities
and thus require large tracts of suitable well-connected habitat to maintain viable populations. Only
small tracts of woodland 2-3ha in extent are present and connected to the site to the east, and it is
considered unlikely that these areas of habitat would be sufficient to support any dormouse population
within the wider arable-dominated landscape to the east. As a result of these factors it is considered
that the site is likely to be of negligible importance for dormice and this species is not considered further
in this report.
Invertebrates
3.86 Much of the site was considered to be of low value for invertebrates, as it comprises intensively
managed arable land. Valuable habitats are limited to the field boundaries (hedgerows, scrub, ruderals,
longer grasses).
28
3.87 The site is considered likely to support an assemblage of common invertebrates by virtue of these
boundary habitats which are comprised in the majority of native flora. However, the sites potential is
limited by low floristic diversity and intensive arable management. Notable invertebrates recorded
locally are considered unlikely to be present. No elm was recorded in the hedgerows, as required for
breeding by white letter hairstreak, and habitats were considered sub-optimal for wall butterfly, due to
the tall sward of the grasses and ruderals.
3.88 The site is therefore considered to have only site value for invertebrates.
Otter and Water Vole
3.89 There are records for water vole within 0.4km of the site, these being associated with Doggetts LoWS.
However the most recent record from this site is from 1996 (i.e. over 20 years old). The ditches within
the study area were considered to provide sub-optimal habitat for water vole, given the combination of
high shading by associated hedgerows, minimal emergent vegetation and low water levels (almost fully
dry at the beginning of spring in March 2019). Hence it is considered that water vole are likely absent
from site. Furthermore, otter are also considered likely absent, as due to periodic drying of both the
ditches and on-site pond, which drives the conclusion that fish are highly unlikely to be present.
3.90 The site is considered to be of negligible importance for both of these species and they are not
considered further in this report.
Reptiles
Preliminary Assessment
3.91 The field boundary ruderal habitats, the semi-improved grassland to the north of the site, and the
improved grassland belt through the centre, were considered to offer opportunities for foraging,
dispersal and basking, whilst hedgerows were considered to offer opportunities for reptiles to move
through the landscape, seek refuge and hibernate. The majority of the site was considered unsuitable
habitat, due to periodic soil disturbance associated with the arable use of the site.
Presence/ Likely Absence Survey
3.92 Previous surveys conducted in 2016 (Lockhart Garett, July 2017) confirmed the presence of three reptile
species on site; slow-worm, common lizard, and grass snake. Peak adult counts were 10 for slow-worm,
14 for common lizard, and 1 for grass snake, over 120 mats deployed.
3.93 Suitable habitat on site is limited to the field boundaries and a patch of semi improved grassland to the
north, amounting to a total area of approximately 2.5ha, so the deployment of 120 mats is significantly
above the recommended density of 10 p/ha of suitable habitat (Froglife, 1999). However, to match the
previous survey effort and foster comparability of results, 120 mats were also deployed across the site
for the current survey.
3.94 The update survey confirmed the continued presence of all three species, though only one juvenile was
recorded for grass snake. Reptiles were present throughout the site, with the highest found on the
central and northern boundaries. The peak count of slow-worm was significantly higher than that
recorded in 2016. The population of slow-worm classed as ‘good’ and the population of common lizard
as ‘low’, according to the Froglife (1999) standard, following adjustment of peak counts to reflect the
29
increased survey effort above the recommended mat density of 10 p/ha of suitable habitat. Results are
summarised below, with detailed results provided in Appendix 11.
Table 15. Reptile survey results summary & population assessment (Froglife 1999).
Species Peak Adult Count Peak Count Adjusted for
Enhanced Survey Effort Population Class
Common lizard 15 3 Low
Slow-worm 58 12 Good
Grass snake 0 (1 juvenile only) - Low
Adder 0 N/A N/A
Importance
3.95 Whilst the reptile population on site is not considered to be of substantive ecological importance alone,
all common reptiles are protected from killing, injury and sale under the Wildlife and Countryside Act
1981 (as amended). It is therefore considered that the site is of local level importance for reptiles.
Other Notables Species European hedgehog
3.96 The boundary habitats on site (grasses, ruderals, hedgerows, scrub) and adjoining residential gardens
were considered to provide suitable foraging habitat and refuge / hibernation opportunities for
hedgehog. The site boundary habitats were also considered to provide enhanced ecological linkage
between off-site residential gardens for this species. No hedgehogs were observed on site during the
course of surveys, however they have been recorded recently within 1km and it is assumed they are
likely present on site given the suitability of habitats observed.
Brown hare
3.97 Arable habitats on site and in the surrounding area provide suitable foraging and ‘laying-up’
opportunities for brown hare with hedgerows providing suitable winter refuge. Brown hare were
observed on site during the course of badger and bat surveys, confirming their presence on site.
Harvest mouse
3.98 The combination of cropland, arable field margins, grassland and hedgerows provide a range of suitable
habitats for this species. No evidence of harvest mouse was found during surveys, however there are
local records within 1km and it is considered that they could potentially be present.
Polecat
3.99 The site was considered potentially suitable for this species, which favours farmland and woodland
habitats, both of which are present locally.
Common toad
3.100 With a number of ponds in the local landscape, it is considered that terrestrial habitats on site may
potentially be used by common toad. This species is known to be present locally, having been recorded
30
in P5, 280m from site. The on-site pond (P11) was also considered potentially suitable for breeding,
though no evidence of this was recorded during surveys.
Importance
3.101 Although no evidence of three of the above species was found, the site provides suitable habitat and
low numbers of notable species could be present, therefore other notable species are considered to be
of site importance.

4.0 Impacts, Mitigation and Enhancement Measures
Description of Development
4.1 An outline planning application for the demolition of numbers 148 and 150 Ashingdon Road and the
development of 665 residential dwellings (C3), a community facility (D1), open space and associated
infrastructure including flood storage and surface water drainage attenuation, with all matters
unreserved for 233 residential dwellings comprising Phase 1 of the proposals, and all other matters
reserved except for Access and Layout.
4.2 On-site open space provision is proposed to comprise 4.85ha of natural/semi-natural open space,
0.14ha of play space, a 0.15ha bike trail youth facility, and 0.26ha of allotments.
Designated Sites
European Designated Sites Construction Impacts
4.3 At 1.9km from the site, the closest European designated site (The Crouch & Roach Estuaries SPA &
Ramsar) is as such a distance that direct impacts such as pollution, disturbance from construction or
habitat loss will not occur.
Occupation Impacts
4.4 The site falls within the ZoI of three Essex coastal European designated sites under the Essex RAMS.
These sites form part of the Essex Estuaries SAC and are underpinned by national SSSI designations. The
nearest of these sites at 1.9km southeast is The Crouch and Roach Estuary SPA & Ramsar. As the
proposed development is a relevant residential development (i.e. for more than one dwelling), it is
therefore possible that European designated sites will suffer from indirect effects through increased
recreational pressure (when considered alone or in combination with other developments). This could
have an adverse effect at the international level.
Mitigation Measures
4.5 Mitigation is set out in detail within an accompanying Habitats Regulations Assessment (HRA; SES,
October 2019). In accordance with the Essex RAMs, a financial contribution to the RAMS of £122.30 per
unit will be provided by the developer to fund strategic off-site measures such as wardening and signage
at coastal European protected sites.
4.6 In addition, as the development is for more than 100 homes, a combination of on-site and off-site
mitigation measures will be employed to ensure the integrity of nearby European designated sites. On
site mitigation will be provided in the form of Suitable Alternative Natural Greenspace (SANGS), to draw
potential recreational users, particularly dog-walkers, away from designated sites.
4.7 Guidelines for the creation of SANGSs are well defined by Natural England in relation to the Thames
Basin Heaths SPA. They are required to be suitable publicly accessible areas of semi-natural character,
within 400m of the proposed development, providing 8ha of semi-natural open space for every increase
of 1,000 new residents.
32
4.8 The average household size taken from the UK Census data for 2011 is 2.4 persons. Given the likely
increase in population resulting from this proposed development, if the development was within the
ZoI of the Thames Basin Heaths SPA then a SANGS provision of approximately 12.7ha would be required
((665 x 2.4) x 0.008). This high level of SANGS is necessary to mitigate effects on ground nesting birds
on heathlands with unlimited public access and, while a useful benchmark, is considered more than that
required for sites designated for wintering waterbirds, where disturbance is limited primarily to dog
walking on coastal paths and noting also that mudflats exposed at low tide are generally inaccessible to
dog walkers themselves though sometimes not to dogs. Hence a lower level of SANGS is considered
acceptable when coupled with access to adjacent Public Rights of Way (PRoW) providing adequate dog
walking walks up to 2.7km in length within and adjacent to the site.
4.9 The development proposal includes 4.85ha of natural/semi-natural open space provision within which
required SANGs features will be incorporated i.e. 38% of the recommended SANGS area required under
guidelines for the Thames Basin Heaths SPA. This provision is delivered in line with the Concept
Statement for Policy SER8 of the Rochford Local Development Framework Allocations Plan (2014) “At
least 3.6 hectares of natural/semi-natural greenspace which is publicly accessible should be provided
and integrated into the development. The calculations of greenspace requirements are based on 500
dwellings being provided on the site. If a greater number are provided, the provision of such facilities
should increase proportionately.”
4.10 The open space provision provides sufficient area to incorporate linear and circular on site dog-walking
routes. On site paths will provide an attractive route through semi-natural green space of c.1km in
length. A new formal linear footpath will link Oxford Road in the north to The Drive in the south,
connecting the onsite SANGs to the local greenspace network, in particular paths leading west and south
west, which in turn connect with other offsite green infrastructure nearby. Further informal mown paths
will link to the formal linear footpath, a providing circular walking route within the site. The route will
have dog waste bins, signage and will be specifically designed to encourage dog walkers and other users.
Signage and leaflets will be used to inform residents of the SANGS area and reason for it, which is
recreational diversion from the foreshore on the Crouch and Roach Estuaries SPA and Ramsar to reduce
disturbance to wintering waterbirds.
Residual Effects
4.11 Construction impacts are considered negligible.
4.12 With the implementation of the above measures, it is considered that the operational phase impacts
and residual effects upon European designated sites will be negligible.
UK Statutory Designated Sites Construction Impacts
4.13 The nearest SSSI (excluding those underpinning the coastal European designated sites discussed above)
is Hockley Woods SSSI. At 3km west of the site this is considered to be at such a distance that direct
impacts such as pollution, disturbance from construction or habitat loss will not occur. This is also
considered to be the case for Magnolia Fields LNR, at 0.8km northwest.
33
Occupation Impacts
4.14 The site does not fall within the IRZ relating to residential development for Hockley Woods SSSI, and as
such, consultation with Natural England in regard to potential risks is not considered necessary.
4.15 Magnolia Fields LNR is already managed for public access and recreational pressure through the
inclusion of public footpaths. Post-development the walking route to reach this site will be
approximately 1.3km, via existing residentially developed roads. It is considered unlikely that many
residents of the development will either walk this distance or choose to drive to the LNR, given the
extent of alternative semi-natural open space that will be provided on-site, and the closer proximity of
existing publicly accessible LoWS (in particular Doggetts Pond) and attractive PRoW (Doggetts Chase) to
the east. As such the increase in recreational pressure as a result of the development is likely to be
insignificant.
Mitigation Measures
4.16 Increases in recreational pressure on nearby statutory designated sites are considered to be insignificant
therefore mitigation is not required.
Residual Effects
4.17 Construction impacts are considered negligible.
4.18 It is considered that operational phase impacts and residual effects upon UK statutory designated sites
will be negligible.
Non-statutory Designated Sites Construction Impacts
4.19 At 0.1km east of the site, the closest non-statutory designated site (Doggetts LoWS) is as such a distance
that direct impacts such as disturbance from construction could occur. This could have an adverse effect
at local level.
Occupation Impacts
4.20 Doggetts Pond LoWS is already managed for public access and recreational pressure; visitors are
encouraged by the sites fishing lakes, managed by Essex Leisure Fisheries, and the public footpath
linkage through the site. However, given the scale of the proposed development and close proximity to
this site, it is considered likely that increased recreational disturbance could occur once the
development is occupied. This could have an adverse effect at local level.
Mitigation Measures
4.21 The provision of 4.85ha of natural/semi-natural open space on site will serve to decrease the
recreational pressures placed on Doggetts LoWS.
4.22 To address potential direct impacts during construction, a Construction Environmental Management
Plan (CEMP) should be prepared prior to commencement. This should include risk assessments of any
34
potentially damaging activities and identify practical measures to avoid and minimise risk of impacts,
e.g. sensitive timings and precautionary working methods.
4.23 To mitigate for potential increases in disturbance post-occupation, a Landscape and Ecological
Management Plan (LEMP) and Ecological Enhancement Strategy (EES) for Doggetts LoWS should be
prepared during the design and construction phases of the scheme, in consultation with relevant bodies
such as the Council, Natural England and the Essex Wildlife Trust. This should detail practical measures
to minimise disturbance to sensitive features and enhance the site for wildlife long term. This could
include e.g. installation of dead hedging around smaller ponds to prevent dog entry, selective felling of
willow scrub to reduce pond overshading, and a treatment program to eradicate invasive flora (Japanese
knotweed) from the site.
Residual Effects
4.24 With the implementation of the above measures, construction impacts, operational impacts and
residual effects will be reduced to negligible.
Habitats Construction Impacts
4.25 Construction will lead to the loss of a range of habitats. The great majority of permanent habitat loss
will be low-value arable, which is nonetheless known to be utilised by notable fauna such as brown hare.
4.26 In addition, the existing scrub and ruderal boundary habitats adjoining residential to the north, west
and south will also be lost. These habitats while lacking floristic diversity provide habitat for reptiles, a
variety of birds, and likely notable species such as hedgehog.
4.27 Finally, H3 (480m in total length or approx. 270m excluding significant gaps), which runs east-west
through the centre of the site, will be lost in entirety to facilitate excavations required for surface water
drainage. This hedgerow does not qualify as ‘Important’ and is defunct at present, limiting its value as
connecting habitat for fauna. However it nonetheless qualifies as a HoPI under the NERC Act 2006.
4.28 Other impacts such as pollution events, damage of retained trees and their roots and indirect impacts
through increased lighting levels are also possible.
4.29 These impacts are considered potentially adverse at up to local level.
Occupation Impacts
4.30 Potential occupation phase impacts include increased recreational pressure on retained habitats,
pollution events, and indirect impacts through increased lighting levels. These impacts are considered
potentially adverse at up to local level.
Mitigation Measures
4.31 The development proposal has sought to avoid and minimise impacts by retaining and buffering the
most valuable habitat on site, H2, an ‘important’ hedgerow that also qualifies as HoPI.
35
4.32 Loss of H3, existing trees and scrub/ruderal boundary habitats where necessary to facilitate the layout
and drainage works will be mitigated for through compensatory planting. Compensatory planting will
also serve to mitigate for any physical damage / disturbance to retained hedgerows and trees.
4.33 Loss of H3 will be mitigated through new native species-rich hedgerow planting within the eastern POS.
Approximately 180m of new native species-rich hedgerow will be planted to define the boundaries of
the proposed allotments to the north. A further approx. 80m will be replanted along the easternmost
section of the existing H3. Finally, approx. 200m of new native species-rich hedgerow will be planted to
link these two features, running north-south along the eastern boundary. The new hedgerows will
provide continuous connecting, foraging and refuge/nesting habitat for a variety of fauna. Further native
hedgerow planting will also be incorporated within smaller POS within the developed area, amounting
to an approx. 100m additional length.
4.34 Existing trees to be lost are primarily incorporated within H3 or are occasional smaller trees/ shrub
species along the southern, western and north boundaries of the site. The most notable tree requiring
removal to facilitate access is the mature oak adjacent Holt Farm School on Ashingdon Road (T1, Sharon
Hosegood Associates AIA Report, October 2019). Loss of existing trees where unavoidable will be
mitigated through extensive new tree planting within new POS, again in excess of tree losses. This will
comprise of predominantly native tree species. In addition, further specific mitigation will be provided
for the loss of T1, including three new street trees, a community orchard, school tree planting and
sustainable use of the tree trunk for art/seating (Sharon Hosegood Associates AIA Report, October
2019).
4.35 Loss of existing scrub and ruderal habitats along the western, northern and southern boundaries will
also be mitigated for within the eastern POS landscaping. New scrub and native shrub planting will be
utilised to buffer ecologically sensitive features, while a low-intensity management approach within
grassland areas (see 4.43) will encourage the natural development of ruderals within the sward, while
also ensuring any one species does not become over-dominant.
4.36 New on-plot and boundary tree and hedgerow planting will also be incorporated along the northern,
western and southern boundaries of the site, focused around car parking areas and to the rear of the
proposed gardens, to create a green buffer in perpetuity between new and existing development, as
detailed in the SER8 Concept Strategy for the site allocation.
4.37 The total loss of arable fields will not be mitigated for as this type of habitat is considered to be of
generally low ecological value and is ubiquitous in the surrounding landscape.
4.38 To address potential direct impacts during construction, such as risk of pollution events and damage to
retained trees/hedgerows, a CEMP should be prepared prior to commencement as detailed in 4.23.
Hedgerows and trees should be protected from damage (e.g. through root compaction) during
development through the erection of suitable fencing such as HERAS fencing.
4.39 Retained trees, hedgerows and the on-site pond will be protected from potential indirect impacts of
increased nocturnal lighting via the implementation of a wildlife-friendly lighting scheme throughout
the development, which maintains ‘dark zones’ and avoids direct lighting of ecologically sensitive
features such as tree canopies. Further details on appropriate specification are provided within the bat
mitigation section below.
36
4.40 Risk of increased recreational disturbance post-occupation will be guarded against through the
provision of appropriate signage and new planting of native scrub and shrubs (see 4.36), that will act as
natural barriers to access for ecologically sensitive features, e.g. around the retained pond and badger
setts.
4.41 Japanese knotweed will be eradicated from the area to the south of the site. Excavation and removal is
considered to be the most appropriate approach given the proposal to install new drainage along the
southern boundary where the existing stand is located and the proximity of new residential properties
proposed. The recommended treatment approach is fully detailed in an accompanying report (SES,
Japanese Knotweed Survey, October 2019).
4.42 Lastly, a LEMP will be prepared for the site detailing how retained and newly-created habitats will be
managed long term to ensure their value for wildlife. This will detail measures such as mowing regimes,
litter removal, silt removal from the pond as necessary, fish removal and invasive species removal.
Enhancements
4.43 Due to the relatively low ecological value of the majority of existing habitat on site, the proposed
retention of the most valuable habitat (H2), and the inclusion of over 4.85ha of natural/semi-natural
open space within the proposals, development of the site offers an opportunity to deliver measurable
biodiversity net gain in accordance with paragraphs 170 and 174 of the NPPF. It is recommended that
proposed enhancements are detailed in an EES for the site.
4.44 Enhancement measures will include the creation of new native-species rich hedgerows, additional
native tree planting, and sowing of wildflower/meadow mixes and maintenance of a tall sward in some
landscaped areas (e.g. within attenuation basins). Emorsgate EP1 pond edge mixture is suitable where
conditions are likely to remain waterlogged for much of the year, or Emorsgate EM8 meadow mixture
for wetlands is suitable for areas likely to be subject to winter inundation only, remaining dry in summer.
The pond could be further enhanced by managing levels of shading and digging out to reduce the
frequency with which this feature dries out.
4.45 The biodiversity benefits to be delivered by the scheme could be evidenced using the DEFRA Biodiversity
Metric Calculator, which would quantitatively demonstrate adherence to the relevant planning policies.
Residual Effects
4.46 During construction it is considered that habitat loss associated with site clearance will represent an
adverse effect at the site level. Other potential construction impacts may be reduced to negligible
through the measures advised.
4.47 Post-development, compensatory habitat and higher-value new habitats will be provided, addressing
temporary habitat loss during construction. Through this and the implementation of the above
additional measures, the residual effect on habitats is predicted to be beneficial.
37
Protected Species Badgers
4.48 Badgers are legally protected under the Protection of Badgers Act (1992) and as such, are of material
consideration when applying the principals of the NPPF (MHDLG, 2019).
Construction Impacts
4.49 Drainage and/or road and dwelling construction works will require clearance and excavation within 20m
of active subsidiary setts S2, S3, S4 and S7, active outlier sett S5, and disused outlier sett S6 (see Sett
Location Plan, Appendix 7).
4.50 Significant excavation works within 20m of the main badger sett (S1) will be avoided; however, within
this area it will still be necessary to excavate and install a new culvert and create an approx. 0.5m high
bund over the existing sewer line. Furthermore it is considered likely that some heavy machinery will
need to intrude within 20m of the main sett in order to carry out more significant excavations required
for flood storage outside of this zone.
4.51 As badger tunnels may extend up to 20m from sett entrances, these works have potential to destroy or
damage setts, or disturb badgers while occupying a sett (Natural England, 2009), all of which are
offences under the Protection of Badgers Act.
4.52 Subsidiary setts S4 and S7 and outlier sett S5 will be permanently lost during construction. Proposed
drainage excavation works are likely to destroy all or most of the existing sett entrances. Even where
this is not the case, retention post-development is not considered desirable in light of the proposed
layout, as close proximity to proposed properties and roads would likely be associated with too much
disturbance to any badgers occupying these setts post-occupation.
4.53 Active subsidiary setts S2 and S3 and main sett S1 are outside of the proposed development area.
Temporary impacts to these setts during construction are likely due to necessary drainage and flood
storage excavation works, which may damage existing tunnels. However destruction of the setts is
considered unlikely, as existing sett entrances will not directly be impacted by the footprint of the
proposed works. In addition it is considered that the majority of tunnels will likely extend away from the
location of proposed works, due to a history of use of heavy machinery and periodic soil disturbance
within the arable field. Hence it is considered feasible to retain these setts post-development.
4.54 Given that all six active setts on site will be impacted during construction, it is considered that
construction impacts could be adverse at up to local level.
Occupation Impacts
4.55 Subsidiary setts S2 and S3, and the main badger sett S1, will be retained post development. These setts
could be subject to increased recreational disturbance (e.g. disturbance from dogs and other domestic
animals). This is predicted to have an adverse effect at the site level.
38
Mitigation Measures
4.56 As excavations will be required within 20m of all six active sett entrances, a Natural England licence will
be sought for permission to close the setts. Closure will ensure no badgers are at risk of being killed or
injured while occupying the setts during the works. Sett closure is only possible between July to
November, to avoid the badger breeding season.
4.57 To minimise the impacts of the development on the badger population currently occupying the site,
closure of existing setts will be on a temporary basis wherever possible. As previously noted, active
subsidiary setts S4 and S7, active outlier sett S5, and disused outlier sett S6 will be permanently lost as
they will be directly impacted by construction activities and are considered likely to be subject to too
much disturbance during the occupation phase if retained. However, the main sett (S1) and subsidiary
setts S2 and S3 will be closed only temporarily to undertake required drainage and flood storage
excavation works and will thereafter be re-opened.
4.58 Once the necessary works are complete, a minimum buffer of 20m will be demarcated around the three
active setts to be retained and visually marked with fencing and signage. Any further excavation within
this zone will then be prohibited and if any other works (e.g. vegetation removal, use of vehicles etc)
are required within the zone the potential impacts will be assessed by a suitably qualified ecologist and
suitable mitigation measures implemented to ensure the sett is not affected by the works.
4.59 The risk of damage to the main sett, the most valuable feature to the badger population occupying the
site, will be minimised as far as is possible through locating all major flood storage excavation works
outside of the 20m buffer zone from this sett. Excavation works within the 20m buffer zone will be
limited to the digging of one trench to install a new culvert. Additional works with the potential to impact
the sett will be limited to the installation of a bund over the existing sewer line and some likely intrusion
of heavy machinery into the 20m buffer area to facilitate excavation works outside this zone. This
approach will also reduce the time it takes to complete works within 20m of the main sett, so that it will
likely need to be closed for a period of only 2-3 weeks.
4.60 In addition, the construction program will be specified to allow for a phased approach to sett closure to
be followed. The main sett will be closed first, while all five other active subsidiary and outlier setts on
site will remain open to ensure the badgers on site have alternative locations to disperse to while works
are undertaken within 20m of the main sett over a 2-3 week period. Once these works are complete
and the main sett can be re-opened, then closure of the outlier and subsidiary setts will follow.
4.61 It is considered that this mitigation approach will serve to reduce the degree and duration of likely
impacts on badgers to such an extent that provision of an artificial sett to mitigate for the temporary 2-
3 week closure of the main sett is not proportionate in this case. However, Natural England will
determine the specific details of mitigation required through the licencing process. As provision of an
artificial sett is often the standard approach where a main sett is to be closed, it is possible that they
may consider this to be required, particularly if plans change and the main sett is required to be closed
for a longer period and/or at the same time as closure of other subsidiary and outlier setts on site. If an
artificial sett is later deemed to be required as mitigation, this will need to be delivered in an area that
will not be disturbed during construction (likely nearby/adjacent site, given the extent of flood storage
excavations required within the site itself), that is within the territory of the badger clan using the site,
and ideally as close to the existing main sett as possible. A bait marking survey may be required to
determine the extent of the extant badger clan territory and aid in locating this mitigation.
39
4.62 In addition to the mitigation detailed above, general precautionary measures will be put in place
throughout construction, to ensure that in the event of a badger coming on to the site, the risk of injuring
and killing is minimised. This will entail:
• Covering any trenches at night or leaving a plank of wood leant against the side to ensure they
can escape if they were to accidentally fall in, and;
• Storing chemicals in a sealed compound (following COSHH guidance),
• Toolbox talks to contractors to ensure ability to identify and flag up any possible badger setts
during construction and;
• Regular clearance of litter from the site.
4.63 Furthermore, as badgers are prolific sett builders, an updated badger survey will be undertaken prior to
the commencement of construction, to establish the current baseline and inform a detailed strategy for
the CEMP.
4.64 To reduce the likelihood of recreational disturbance to badgers occupying retained setts post-
construction, scrub and shrub planting will be utilised to naturally buffer the setts and decrease the
likelihood of incursion into the surrounding area e.g. by dogs and walkers. H2 and the existing pond will
also be retained. Together with new connecting hedgerow planting, this will ensure connectivity along
the eastern boundary of the site and access to water is retained post-development.
Enhancements
4.65 Retention of existing hedgerow and creation of new hedgerow, grassland and scrub habitats within the
proposed open space to the east of the site will provide improved foraging and sheltering resources for
badgers post development. Fruiting species will be included in the planting scheme and once mature,
these will provide additional food resources for badgers (and other wildlife). Recommended planting
lists are provided in Appendices.
Residual Effects
4.66 By minimising the extent and length of works in the vicinity of the main sett, phasing sett closures, and
utilising standard precautionary methods, it is considered that construction phase impacts on the local
badger population can be reduced to a negligible level.
4.67 Through retention and buffering of the main sett and two subsidiary setts, retention of H2, and new
tree and hedgerow planting within the eastern POS, it is considered that occupation phase and residual
effects on badgers will be reduced to negligible.
Bats Construction Impacts
4.68 There is potential for the bat assemblage currently utilising the site for foraging and commuting to be
adversely affected through increases in artificial lighting and habitat loss during the construction phase.
Impacts could disrupt dark corridors present along the site boundary habitats, potentially having an
adverse effect at the site level by driving abandonment of foraging and commuting pathways, as well
as roosts (if present).
40
4.69 Risk of direct impacts (killing, injury, loss of a roost) is considered to be very low, as the hedgerow (H2)
containing the only two trees identified as being potentially suitable for roosting bats is to be retained
and buffered under the development proposal. Some crown pruning works could potentially be required
to T4 (as referenced in the Sharon Hosegood Associates AIA Report, 2019), due to the proximity of
nearby power lines and presence of deadwood within the crown. However, this tree is only of a ‘low
suitability’ for roosting bats, and it is considered highly unlikely that crown pruning works would impact
the only suitable roost feature recorded on this tree, which is located low in the crown and close to the
main stem.
Occupation Impacts
4.70 During the occupation phase, there is potential for indirect effects through increased light levels which
could result in the abandonment of foraging and commuting pathways, as well as roosts (if present)
which would constitute an adverse effect at the site level. Disturbance to roosting bats (both directly
and indirectly) is an offence under UK and EU legislation.
Mitigation Measures
4.71 Proposals retain H2 and the existing pond which provide foraging and commuting habitat for bats. Loss
of H3 and existing scrub/ruderal boundary habitats adjoining existing residential will be mitigated
through compensatory planting, as detailed in the Habitats section above. This will include new linear
native species-rich hedgerow planting to provide north-south connectivity along the eastern boundary
of the POS. Given that bat activity surveys identified only low levels of foraging and commuting activity
on site and did not highlight H3 (to be removed) as a particularly important feature for foraging and
commuting bats, this mitigation is considered to be sufficient to address the potential for any negative
impacts on local bat populations.
4.72 The indirect impact of artificial lighting requires mitigation to ensure the local bat population are
protected from disturbance. Particular care should be directed to retaining dark corridors along
hedgerows. To minimise detrimental effects of light pollution on local bat populations, mitigation will
include:
• Minimising the lighting levels across habitats of where potential foraging/commuting corridors
are situated (i.e. around trees and hedgerows) especially all boundary habitats;
• Minimising spill of light with the use of directional luminaires, shields, baffles and louvers to
direct light where it is needed and prevent light being directed over and around the features
concerned, e.g. avoid backlighting and overspill onto tree lines, and;
• Orientating the pitch of light away from any potential bat foraging/commuting corridors to
allow a dark corridor to persist.
4.73 Site lighting around key features likely to be used by roosting, foraging or commuting bats will be
avoided during both the construction and occupation phases. If lighting is necessary, then there are a
number of ways to minimise the effect of lighting on bats (and other nocturnal species such as badgers
and owls). The following mitigation strategies have been taken from the Institution of Lighting
Professionals and Bat Conservation Trust’s Guidance Note 08/18 Bats and artificial lighting in the UK
(2018) and other referenced sources:
41
• In general, light sources should not emit ultra-violet light to avoid attracting insects and thus
potentially reducing numbers in adjacent areas, which bats may use for foraging. Metal halide
and fluorescent sources will not be used.
• LED luminaires should be used where possible. A warm white spectrum (ideally <2700Kelvin)
will reduce blue light component. Luminaires should feature peak wavelengths higher than
550nm to avoid the component of light most disturbing to bats (Stone, 2012).
• The height of lighting columns should be limited to 8m and the spacing of lighting columns
should be increased to reduce spill of light into unwanted areas such as hedgerows and trees
(Fure, 2006). Only luminaires with an upward light ratio of 0% and with good optical control
should be used. Luminaires will always be mounted on the horizontal, i.e. no upward tilt.
• Other ways to reduce light spill include the use of directional luminaires, shields, baffles and/or
louvres. Flat, cut-off lanterns are best. Additionally, lights will be located away from reflective
surfaces where the reflection of light should spill onto potential foraging/commuting corridors.
Internal luminaires can be recessed where installed in proximity to windows to reduce glare
and light spill. Where windows and glass facades etc. cannot be avoided, low transmission
glazing treatments may be a suitable option in achieving reduced illuminance targets.
• Lighting that is required for security or access should use a lamp of no greater than 2000
lumens (150 Watts) and be PIR sensor activated on a short timer (1 minute), to ensure that the
lights are only on when required and turned off when not in use (Jones, 2000; Hundt, 2012). A
control management system can be used to dim (typically to 25% or less) or turn off groups of
lights when not in use.
4.74 To guard against residual risk of direct harm, if pruning works to T4 (low suitability for roosting bats) are
required, a ‘soft fell’ approach should be used, whereby limbs are removed one at a time, lowered gently
to the ground using ropes, and left in place for 24 hours before being chipped or removed from site, to
allow any bats to escape in the unlikely event they are present.
4.75 No works to the off-site oak at TQ 87691 91690 (high suitability for roosting bats) are known to be
proposed at this stage. However, if felling or pruning of this tree was to be required (e.g. to facilitate
construction access via Doggetts Chase), then three emergence/re-entry surveys would be required to
determine the presence/likely absence of a roost and characterise the nature of any roost present. If a
roost was found, a Natural England licence would then need to be applied for before any works to the
tree could take place. If the roost was to be lost, mitigation would need to be provided, likely in the form
of bat boxes installed on retained trees.
Enhancements
4.76 The inclusion of integrated bat boxes within new residential properties will provide an enhancement for
roosting bats within the site. A variety of bat boxes that can integrate seamlessly into the design of new
buildings are available, such as the Habibat Bat Box, which can be supplied plain for a rendered finish,
or faced with brick. It is recommended for 20 bat boxes to be installed within new homes close to the
eastern boundary of the development and main POS.
42
4.77 Planting of new hedgerows will serve to further enhance the site for bats by improving north-south
connectivity within the site and in turn improving linkage to the wider habitat to the east. New
hedgerow and tree planting will also offer an additional foraging resource. To maximise benefit, new
hedgerows will be native-species rich, as this is most attractive to invertebrates, and incorporate maiden
trees at intervals, as bats tend to favour hedgerows with a more complex structure.
4.78 In addition, plant species of known benefit to bats, principally nectar-rich species which attract moths
and other nocturnal invertebrates will also be included within the landscaping scheme which will also
enhance biodiversity in general. Recommended planting lists are provided in Appendices.
Residual Effects
4.79 With the implementation of the above measures, construction impacts are predicted to be negligible.
4.80 With the implementation of the above measures and the provision of improved foraging resources
within retained and created habitats, it is predicted that the residual effects upon bat populations will
be beneficial at the site level.
Breeding Birds Construction Impacts
4.81 Impacts during construction consist of potential nest destruction and disturbance, which constitutes an
offence under the The Wildlife and Countryside Act 1981 (as amended). In addition, construction will
lead to loss nesting and foraging habitats, including open arable land, scrub, trees and hedgerow. These
are considered adverse effects at the site level, given the limited assemblage of mainly common species
currently utilising the site for breeding.
Occupation Impacts
4.82 It is possible that breeding birds will be affected post-development through increased recreational
disturbance (e.g. disturbance from dogs and other domestic animals). This is predicted to have an
adverse effect at the site level.
Figure 1: Habibat Bat Box faced with red brick, incorporated within wall at gable end.
43
Mitigation Measures
4.83 Nesting and foraging habitat loss will be minimised through the retention of H2. This hedgerow will be
protected from damage (e.g. through root compaction) during development through the erection of
suitable fencing such as HERAS fencing.
4.84 Where existing scrub, tree and hedgerow habitats will be lost, this will be mitigated for through
compensatory planting, to include a range of native species that will provide new foraging resources for
berry-eating bird species as well as attract invertebrates for those species reliant on insects. New tree
and hedgerow planting will be in excess of losses to deliver a net gain in nesting habitat for the
development.
4.85 Loss of arable habitat onsite will not be mitigated for; although skylark (a red list species) was considered
to be breeding within this habitat in 2019, only one territory was identified on site and there are
extensive areas of arable cropland to the east of the site offering alternative nesting opportunities for
this species and other ground-nesting farmland birds which may be present locally. Hence it is
considered that displacement from site will not have a significant impact on the local population of
skylark and no specific mitigation for this species is proposed.
4.86 To comply with current legislation and avoid nest destruction, vegetation clearance works affecting
nesting habitat (including hedgerow, scrub, tall grasses/ruderals and open arable) will be scheduled so
that these do not occur during the bird breeding season (i.e. outside the period March-August inclusive).
If this is not possible, a check will be carried out by a suitably qualified ecologist no more than 48 hours
in advance of clearance works. If an active birds’ nest is found within the proposed clearance zone,
suitable avoidance measures will be installed, such as creating a buffer zone with barrier tape around
the nest to ensure that the nest is not damaged or destroyed by the works. The nest will then be
monitored until all chicks have fledged and a suitably experienced ecologist confirms the nest is now
inactive and works can safely proceed.
4.87 Recreational impacts post-development will be mitigated for through measures outlined in the habitats
section, i.e. retention and new planting of hedgerows and creation of dark corridors around sensitive
habitats. In addition, retained and created habitats will be specifically managed to benefit wildlife
(including nesting birds). Specific details will be provided in the LEMP and will include measures such as
a biennial and rotational approach to hedge maintenance to maximise berry production, and timing
maintenance to take place in late winter to ensure that berries are retained as a winter food resource.
Enhancements
4.88 To enhance the site for birds a nest box scheme will be incorporated into the development through the
installation of the following boxes (or similar boxes). Larger nest holes (for example for starlings) will be
avoided as these will likely be taken over by ring-necked parakeets.
• 12 x 1G Schwegler Generalist Bird Box (Figure 2).
• 30 x specialised Manthorpe swift bricks (Figure 3) will be installed within the built development
realm. The bricks should be installed in numbers no less than two per household. A total of 30
bricks should be installed.
44

Figure 3: Manthorpe swift brick.
Residual Effects
4.89 With the implementation of the above mitigation, the effect on breeding birds is predicted to be
negligible during the construction phase and beneficial at the site level during the occupation phase.
Invertebrates Construction Impacts
4.90 Loss of habitat during the construction phase is likely to result in killing and/or injury to a common
invertebrate assemblage only.
Occupation Impacts
4.91 During the occupation phase, there is potential for indirect effects through increased light levels which
could result in the abandonment of habitat. This is predicted to have an adverse effect at the site level.
Mitigation Measures
4.92 Construction impacts to the existing invertebrate assemblage on site will be minimised through the
retention and buffering of H2, as previously discussed.
4.93 The development proposal contains areas of open space which may be utilised to create new
invertebrate habitat areas within the site. The landscaping scheme will provide appropriate habitat and
resources, such as:
45
• New structural planting of treelines, hedgerow and scrub to provide linear features which
some invertebrates fly along, shelter from wind, and warm microclimates;
• Retention of deadwood generated through site clearance in the form of log-piles, which would
be particularly beneficial for stag beetle which are known to be present in the local area;
• Planting of new flower rich areas - invertebrates will benefit from areas able to offer an
abundance of blossom across the season, with shrubs important in spring and then herbs
providing a continuity to late summer. Night-scented plant species such as evening primrose
Oenothera sp., honeysuckle Lonicera sp. and jasmine Jasminium officinale attract moths in the
evening, which would in turn attract foraging bats.
4.94 Artificial lighting will be kept to a minimum and designed to avoid lighting areas of semi-natural
vegetation, with lighting columns of appropriate height, directional lighting and the use of baffles.
Where possible wavelengths should include a minimal UV component, as previously discussed in the
bat mitigation section above.
Residual Effects
4.95 With the implementation of the above measures, it is considered that the residual effects on
invertebrates will be beneficial.
Reptiles Construction Impacts
4.96 The site supports populations of common lizard, slow-worm and grass snake utilising grassland and field
margins during the summer and hedgerows and scrub for shelter during the winter. Although H2 along
the eastern boundary will be retained and buffered, H3, the adjacent grassland strip running east-west
through the site, and suitable scrub and ruderal habitat along the northern, western and southern
boundaries, will be lost to facilitate drainage works and other construction activities. This could result
in killing and / or injury to individuals, an offence under the Wildlife and Countryside Act 1981. This is
predicted to have an adverse effect at the local level.
Occupation Impacts
4.97 During the occupation phase there is a risk of disturbance during management of retained and created
habitats, as well as increased predation of reptiles e.g. due to increases in the number of local pet cats,
which may reduce their viability and thus constitutes an adverse effect at the site level.
Mitigation Measures
4.98 To mitigate for risk of killing and/or injury to reptiles during construction, reptile exclusion fencing will
be erected around the boundaries of the site where suitable habitat exists. Along H2 where suitable
habitat will be retained, exclusion fencing will be erected to prevent reptiles within this area from
coming into the construction zone and potentially being injured. Where reptile habitat will be lost
elsewhere, these areas will be trapped out for reptiles and any individuals caught will be moved to an
appropriate receptor area, within which enhancements to improve the quality of the habitat and its
ability to support reptiles will be delivered.
46
4.99 ARG UK guidance requires a minimum of 70 suitable days trapping, with a refugia density of 100/ha
between April and September (HGBI, 1998) for the population class sizes present. Trapping effort is
restricted to periods of appropriate weather and must be undertaken when reptiles are active, typically
from mid-March to mid-September, although this is entirely dependent upon temperature and the
arrival of both spring and autumn. Following this period, capture may be concluded following 7
consecutive ‘clear’ trapping visits or at the judgement of the site ecologist.
4.100 Given the extent of flood storage excavations and other drainage works required to facilitate the
development, very little of the site will remain completely undisturbed throughout the construction
period. It is therefore considered unlikely to be feasible to create a receptor area on-site that is of
sufficient size/carrying capacity to absorb the number of reptiles requiring translocation. Therefore, it
is proposed that reptiles trapped out of boundary habitats to be impacted by the development will be
translocated off-site. A suitable receptor area will need to be identified that is local to the application
site and either already provides suitable habitat or could be enhanced to deliver this. It is suggested that
a Reptile Mitigation Strategy should be produced to detail the proposed approach; this could be secured
as a condition of any future planning approval.
4.101 To reduce residual risk of harm to any reptiles remaining within the impacted boundary habitats post-
translocation, a destructive search supervised by an ECoW will be undertaken. The destructive search
will involve potential reptile habitat being slowly scraped by an excavator using a toothed bucket while
an ecologist supervises and safely removes any reptiles ‘scraped-up’ in the bucket or disturbed on the
ground (Gent & Gibson, 2003). These animals will then be promptly relocated to the receptor site. A
toolbox talk will also be given to site workers and reptile identification information will be displayed on
site. Management will be instructed to always use reptile-sensitive vegetation clearance and
management methods and to maintain long grass buffers around sensitive habitats to be retained.
4.102 On completion of construction, the reptile exclusion fence along retained H2 will be removed. This will
allow reptiles to recolonise the site post-development. New scrub planting and low-intensity
management of grassland within the eastern POS will provide new suitable habitat within the site for
these species. The retained hedgerow (H2) together with new hedgerow planting within the POS will
provide connectivity to the wider environment, fostering recolonization. Provision of log-pile
hibernacula buffered by long-grass areas will also serve to reduce likelihood of predation post-
occupation.
Enhancements
4.103 Through the inclusion of a large area of public open space to the east, incorporating appropriate
enhancements, it is considered that the extent and quality of suitable reptile habitat on site will be
increased post-development. The following measures will be incoporated:
• Creation of log pile hibernacula utilising materials generated through vegetation clearance;
• Areas of open space to be sown with a grass/wildflower meadow mix, subject to a low-
intensity management regime with a longer sward maintained; and
• Creation of new native scrub/hedgerow habitat adjacent to longer grass areas, to provide an
appropriate mosaic of sheltering, foraging and basking opportunities.
47
Residual Effects
4.104 With the implementation of the above mitigation, the effect on reptiles is predicted to be negligible
during the construction phase.
4.105 With the implementation of the above mitigation, the effect on reptiles is predicted to be beneficial
during the occupation phase.
Other Notable Species Construction Impacts
4.106 Brown hare, harvest mouse, common toad, hedgehog and polecat are listed as Species of Principal
Importance under the NERC Act 2006. Brown hare were confirmed as present on site, and suitable
habitat is present for the other species. Should these species be using habitats on site, effects may
include death / injury, habitat loss and fragmentation.
4.107 If present, brown hare is likely to be displaced from arable habitats into the wider landscape however
given the size of the site, the number of animals present is likely to be low and displacement from the
site is considered unlikely to have a significant effect on the local hare population.
Occupation Impacts
4.108 Brown hare are unlikely to remain on site post-development therefore impacts during the occupation
phase are applicable to hedgehog, polecat, common toad and harvest mice, which may colonise new
grassland habitats created within the proposed open space to the east from adjoining arable habitat.
Increased disturbance and predation by domestic animals, as well as increases in road traffic accidents
and recreational disturbance, is possible during the occupation phase which is likely to have an adverse
effect at the site level. Although gardens will provide suitable foraging habitat for hedgehog, if access is
restricted hedgehogs (and other small mammals) are likely to become isolated through fragmentation.
Mitigation Measures
4.109 The risk of construction impacts to hedgehog, harvest mouse, common toad and polecat will be
minimised through the retention and protection of existing hedgerows and associated ditches and
margins. The existing pond, suitable for common toad, will also be retained and protected from
potential construction impacts such as pollution events through methods to be detailed in the CEMP.
4.110 Where clearance of suitable habitat is necessary, precautionary measures will be followed to reduce risk
of direct harm, to include:
• Sensitive timings for works e.g. outside of hedgehog hibernation season (November-March)
• A search by an ecologist for hedgehog and harvest mouse nests prior to clearance, and in
addition for leverets if works take place between March and September
• A two-stage cut of tall grasses and ruderals for common toad, where the first cut is made to a
height of no less than 15cm and 24 hours then left to elapse before remaining vegetation is
cleared to ground level, allowing time for any disturbed animals to move away from the area
48
4.111 Recreational impacts during occupation will be mitigated through measures outlined in the habitats and
badger section, i.e. retention and enhancement of hedgerows and other retained habitats; creation of
dark corridors around sensitive habitats. In addition, retained and created habitats will be specifically
managed to benefit wildlife (including hedgehogs, polecat and harvest mice).
Enhancements
4.112 The green space and garden habitats will provide preferred habitats for foraging hedgehog. Given the
findings of recent studies (Johnson, 2015) highlighting the decline of hedgehogs throughout the UK in
recent years, the provision of access points into residential gardens is an important measure providing
access to foraging resources. To facilitate the movement of hedgehogs through the site, it is
recommended that one 13cm x 13cm hole should be provided within all new lengths of garden (and
where feasible boundary) fencing to permit movement of hedgehogs through back gardens. This size
gap is too small for most pets and can be undertaken by raising a fence panel per garden; installing
hedgehog friendly fencing; removing a brick at the bottom of a wall or cutting a hole in fencing / walls.
Residual Effects
4.113 With the implementation of the above measures, it is considered that construction and residual effects
on other notable species will be negligible.

5.0 Summary and Conclusions
5.1 The proposed residential-led development at land East of Ashingdon Road, Rochford has been assessed
for its biodiversity value in general, as well as its potential to support ecological receptors. Further
ecological surveys and assessments (badgers, bats, breeding birds, great crested newt, hedgerows and
reptiles) have been undertaken and are discussed within this report.
5.2 Habitats of biodiversity value are considered to be hedgerows, ponds, semi-improved and improved
grassland, and scrub and ruderal dominated arable boundaries. Ecological features of interest include a
number of statutory and non-statutory designated sites within the zone of influence of the
development; hedgerows (one important, two HoPI); active badger setts; foraging and commuting bats;
trees with potential to support roosting bats; a population of breeding birds; and populations of three
reptile species.
5.3 Table 17 provides a summary of the impacts, mitigation and enhancement measures for each ecological
feature and the residual effects.
5.4 Through implementing the recommended mitigation, it is considered that all significant negative
impacts from the proposed development upon protected and notable habitats and species would be
mitigated in line with relevant wildlife legislation and national planning policy (MFHLG, 2019), and local
planning policy related to biodiversity.

National Planning Policy
The NPPF (MHCLG, 2019) outlines what the planning system should do to contribute to and enhance the
natural and local environment through the following policy statements:
Paragraph 8
Achieving sustainable development means that the planning system has three overarching objectives, which
are interdependent and need to be pursued in mutually supportive ways (so that opportunities can be taken
to secure net gains across each of the different objectives):
c) an environmental objective – to contribute to protecting and enhancing our natural, built and
historic environment; including making effective use of land, helping to improve biodiversity, using
natural resources prudently, minimising waste and pollution, and mitigating and adapting to
climate change, including moving to a low carbon economy.
Paragraph 20
Strategic policies should set out an overall strategy for the pattern, scale and quality of development, and
make sufficient provision for:
d) conservation and enhancement of the natural, built and historic environment, including
landscapes and green infrastructure, and planning measures to address climate change mitigation
and adaptation.
Paragraph 28
Non-strategic policies should be used by local planning authorities and communities to set out more detailed
policies for specific areas, neighbourhoods or types of development. This can include allocating sites, the
provision of infrastructure and community facilities at a local level, establishing design principles, conserving
and enhancing the natural and historic environment and setting out other development management policies.
Paragraph 102
Transport issues should be considered from the earliest stages of plan-making and development proposals, so
that:
d) the environmental impacts of traffic and transport infrastructure can be identified, assessed and
taken into account – including appropriate opportunities for avoiding and mitigating any adverse
effects, and for net environmental gains; and
Paragraph 118
Planning policies and decisions should:
58
a) encourage multiple benefits from both urban and rural land, including through mixed use schemes
and taking opportunities to achieve net environmental gains – such as developments that would
enable new habitat creation or improve public access to the countryside;
b) recognise that some undeveloped land can perform many functions, such as for wildlife,
recreation, flood risk mitigation, cooling/shading, carbon storage or food production;
Paragraph 141
Once Green Belts have been defined, local planning authorities should plan positively to enhance their
beneficial use, such as looking for opportunities to provide access; to provide opportunities for outdoor sport
and recreation; to retain and enhance landscapes, visual amenity and biodiversity; or to improve damaged and
derelict land.
Paragraph 170
Planning policies and decisions should contribute to and enhance the natural and local environment by:
a) protecting and enhancing valued landscapes, sites of biodiversity or geological value and soils (in
a manner commensurate with their statutory status or identified quality in the development plan);
b) recognising the intrinsic character and beauty of the countryside, and the wider benefits from
natural capital and ecosystem services – including the economic and other benefits of the best and
most versatile agricultural land, and of trees and woodland;
c) maintaining the character of the undeveloped coast, while improving public access to it where
appropriate;
d) d) minimising impacts on and providing net gains for biodiversity, including by establishing
coherent ecological networks that are more resilient to current and future pressures;
Paragraph 174
To protect and enhance biodiversity and geodiversity, plans should:
a) Identify, map and safeguard components of local wildlife-rich habitats and wider ecological
networks, including the hierarchy of international, national and locally designated sites of
importance for biodiversity; wildlife corridors and stepping stones that connect them; and areas
identified by national and local partnerships for habitat management, enhancement, restoration
or creation; and
b) promote the conservation, restoration and enhancement of priority habitats, ecological networks
and the protection and recovery of priority species; and identify and pursue opportunities for
securing measurable net gains for biodiversity.
Paragraph 175
When determining planning applications, local planning authorities should apply the following principles:
a) if significant harm to biodiversity resulting from a development cannot be avoided (through
locating on an alternative site with less harmful impacts), adequately mitigated, or, as a last resort,
compensated for, then planning permission should be refused;
b) development on land within or outside a Site of Special Scientific Interest, and which is likely to
have an adverse effect on it (either individually or in combination with other developments),
should not normally be permitted. The only exception is where the benefits of the development
in the location proposed clearly outweigh both its likely impact on the features of the site that
make it of special scientific interest, and any broader impacts on the national network of Sites of
Special Scientific Interest;
59
c) development resulting in the loss or deterioration of irreplaceable habitats (such as ancient
woodland and ancient or veteran trees) should be refused, unless there are wholly exceptional
reasons and a suitable compensation strategy exists; and
d) development whose primary objective is to conserve or enhance biodiversity should be supported;
while opportunities to incorporate biodiversity improvements in and around developments should
be encouraged, especially where this can secure measurable net gains for biodiversity.
Paragraph 176
The following should be given the same protection as habitats sites:
a) potential Special Protection Areas and possible Special Areas of Conservation;
b) listed or proposed Ramsar sites;
c) sites identified, or required, as compensatory measures for adverse effects on habitats sites,
potential Special Protection Areas, possible Special Areas of Conservation, and listed or proposed
Ramsar sites.
Paragraph 177
The presumption in favour of sustainable development does not apply where the plan or project is likely to
have a significant effect on a habitats site (either alone or in combination with other plans or projects), unless
an appropriate assessment has concluded that the plan or project will not adversely affect the integrity of the
habitats site.
Paragraph 180
Planning policies and decisions should also ensure that new development is appropriate for its location taking
into account the likely effects (including cumulative effects) of pollution on health, living conditions and the
natural environment, as well as the potential sensitivity of the site or the wider area to impacts that could arise
from the development. In doing so they should:
c) limit the impact of light pollution from artificial light on local amenity, intrinsically dark landscapes
and nature conservation.
Local Planning Policy
The adopted Rochford Local Development Framework Core Strategy (2011) contains the following policy with
relevance to biodiversity:
Policy ENV1 – Protection and Enhancement of the Natural Landscape and Habitats and the Protection of
Historical and Archaeological Sites
The Council will maintain, restore and enhance sites of international, national and local nature conservation
importance. These will include Special Areas of Conservation (SACs), Special Protection Areas (SPAs), Ramsar
Sites, Sites of Special Scientific Interest (SSSIs), Ancient Woodlands, Local Nature Reserves (LNRs) and Local
Wildlife Sites (LoWSs). In particular, the Council will support the implementation of the Crouch and Roach
Management Plan. The Council will also protect landscapes of historical and archaeological interest.
Part of the site (23.5ha) is allocated for residential development of 500 units (including at least 175 affordable
units) under Policy SER8 of the Rochford Local Development Framework Allocations Plan (2014). This is
expected to accommodate the following infrastructure, services and facilities:
60
• Local highway capacity and infrastructure improvements, including contribution to traffic
management of Ashingdon Road;
• Public transport infrastructure improvements and service enhancements;
• Link and enhancements to local pedestrian/cycling and bridleway network;
• Sustainable drainage systems;
• Public open space;
• Play space; and
• Youth facilities and community facilities.
The Concept Statement for the site allocation details the following expectations in relation to environment
and biodiversity:
• Trees and hedges should be developed in garden areas along the northern, western and southern
boundaries of the site to create a green buffer in perpetuity between new and existing development,
whilst promoting integration.
• The loss of any trees on site or in the vicinity of the site should be appropriately mitigated against,
with the provision of replacement trees on a like-for-like basis.
• Amenity greenspace and appropriate landscaping should be provided throughout the site.
• At least 3.6 hectares of natural/semi-natural greenspace which is publicly accessible should be
provided and integrated into the development. The calculations of greenspace requirements are
based on 500 dwellings being provided on the site. If a greater number are provided, the provision
of such facilities should increase proportionately.
• A green buffer to the east should be provided following the existing tree line further to the east to
soften the boundary of the site. Within this area, a greenway linking Oxford Road in the north to The
Drive in the south should be developed, enhancing access/egress to King Edmund School in the north
and the facilities and services in Rochford town centre in the south. This buffer will not form part of
the development area, but will be situated in the Green Belt to the east of the residential settlement.
The green buffer should take the form of parkland which is publicly accessible and integrated into
the development. Conditions will be attached to ensure that any greenspace provided on or off site
has ecological value. A landscape strategy promoting green links and biodiversity corridors should be
prepared for the site.
• Links to the neighbouring Local Wildlife Site to the east/south east of the site should be explored.
Given the proximity of the site to this area of ecological value, a management plan for the Local
Wildlife Site should be prepared during the design and construction phases in consultation with
relevant bodies such as the Council, Natural England and the Essex Wildlife Trust, given potential
increased recreational pressure on the site. Disturbance of this site should be avoided.
England Priority Species and Priority Habitats
The UK Post-2010 Biodiversity Framework, published in July 2012, has now succeeded the UK Biodiversity
Action Plan. Much of the work previously carried out under the UK BAP is now focussed at a country level.
England Priority Species and Priority Habitats are those that have been identified as being the most threatened
and requiring conservation action under the England Biodiversity Strategy.
61
Badgers
Badgers have historically been given legal protection since 1973 however the Protection of Badgers Act 1992
consolidated and strengthened previous legislation. It is a criminal offence to:
• Wilfully kill, injure, or take any Badger.
• Possess or cruelly ill-treat a badger.
• Possess any dead badger or part of one.
• Possess or control a living, healthy Badger.
• Intentionally or recklessly damage, destroy or obstruct access to a sett, or disturb a Badger whilst it
is occupying a sett.
The maximum fine per offence is £5000; the Countryside and Rights of Way Act 2000 (CRoW) amendment
contains a provision for a custodial sentence of up to 6 months instead of, or in addition to, a fine. Along with
a lengthy development delay until an appropriate mitigation programme has been agreed and completed.
Local authority planning departments should also meet the requirements of the National Planning Policy
Framework (NPPF) 2018; which requires planners not only to protect biodiversity, but where possible to
enhance it. Planning authorities are required to take into account of protected species so an ecological survey
is normally required.
Bats
All UK bat species are protected under European and UK law (Conservation of Species and Habitats Regulations
(CHSR) 2017; Wildlife and Countryside Act (WCA) 1981). Some are also Natural Environment and Rural
Communities (NERC) Act 2006 /UK Biodiversity Action Plan (UK BAP) priority species and local BAP species.
Protected and NERC/UK BAP/local BAP species are a material consideration under the NPPF (MHCLG, 2019).
Hazel Dormouse
Hazel dormice are protected under UK and European law primarily by the WCA (1981) as amended and
regulation 41 of the CHSR (2017). Taken together it is illegal to:
• Deliberately kill, injure or capture any wild animal of European protected species;
• Deliberately disturb wild animals of any European protected species in such a way to be likely to
significantly affect:
• The ability of any significant groups of animals of that species to survive, breed, rear or nurture their
young; or
• The local distribution of that species.
• Recklessly disturb a European protected species;
• Damage or destroy breeding sites or resting places of such animals;
• Deliberately take or destroy the pups of such an animal;
• Possess or transport any part of a European protected species, unless acquired legally; and
• Sell, barter or exchange any part of a European protected species.
62
Birds
All UK wild birds are afforded statutory protection under the WCA (1981) (below). In addition to this statutory
protection British birds are also classified according to their conservation status, including their position on
the Red and Amber lists of Birds of Conservation Concern in the UK 3 (Eaton et al, 2009) and whether they have
been identified as Priority Species under the England Biodiversity Strategy. All British birds are also covered by
the EU Birds Directive.
EU Birds Directive
Under the EU Birds Directive all bird species naturally occurring on the European territory of the EU are
protected. This means they must not be deliberately killed, caught or disturbed, and their mating, breeding,
feeding and roosting habitats must not be destroyed. The taking and destruction of eggs is prohibited as well
as keeping of wild-caught birds
A major provision of the Directive includes the identification and classification of Special Protection Areas
(SPA’s) for rare or vulnerable species which are listed in Annex I of the Directive. The Directive also regulates
the hunting of certain species of birds listed in Annex II, while Annex III regulates the sale, transport, keeping
and offering for sale of certain live or dead game birds. In the UK, the provisions of the ‘Birds Directive’ are
implemented through the WCA (1981)
Wildlife and Countryside Act 1981.
Wild birds in the UK are protected under the WCA (1981). Under this legislation all birds, their nests and eggs
are protected by law and it is an offence, with certain exceptions, to intentionally kill, injure, or take any wild
bird or their eggs or nests (exceptions to this are listed in Schedule 2). In addition, a select group of species
are further listed under Schedule 1 of the Act and these have additional protection that makes it an offence to
disturb these birds at the nest, or to disturb their dependent young.
Birds of Conservation Concern:
Red list species are those that are Globally Threatened according to IUCN criteria, those with populations or
ranges that have declined rapidly in recent years and those that have declined historically and not shown a
substantial recent recovery.
Amber list species are those with an unfavourable conservation status in Europe, those whose population or
range has declined moderately in recent years; those whose population has declined historically but made a
substantial recent recovery; rare breeders; and those with internationally important or localised populations.
Green list species are all regularly occurring species that do not qualify under any of the Red or Amber criteria.
The Green list also includes those species listed as recovering from Historical Decline in the last review that
have continued to recover and do not qualify under any of the other criteria.
63
The Natural Environment and Rural Communities (NERC) Act 2006; Section 41
The Natural Environment and Rural Communities (NERC) Act came into force on 1 October 2006. Section 41
(S41) of the Act requires the Secretary of State to publish a list of habitats and species which are of principal
importance for the conservation of biodiversity in England.
England Priority Species on the list (see below) are those species found in England which have been identified
as requiring action under the England Biodiversity Strategy. The list is used to guide decision-makers such as
public bodies, including local and regional authorities, to have regard to the conservation of biodiversity in
England.
GCN
GCN are protected under S9 of the WCA (1981) and regulation 41 of CHSR (2017). Taken together offences
relevant to this project are likely to be:
• Deliberately kill, injure or capture any wild animal of European protected species;
• Deliberately disturb wild animals of any European protected species in such a way to be likely to
significantly affect:
o The ability of any significant groups of animals of that species to survive, breed, rear or nurture
their young; or
o The local distribution of that species.
• Intentionally or recklessly disturb an animal while occupying a place used for shelter or protection;
• Damage or destroys breed sites or resting places of such animals;
• Deliberately takes or destroys the eggs of such an animal;
• Possess or transport any part of a European protected species, unless acquired legally.
Other Amphibians
Amphibians (common frog, common toad, smooth newt, palmate newt) are protected under Section 9(5) of
the WCA (1981) against:
• Selling, offering or exposing for sale, or having in possession or transporting for the purpose of sale,
any live or dead wild animal or any part of, or anything derived from, such an animal;
• Publishing or causing to be published any advertisement likely to be understood as conveying buying
or selling, or intending to buy or sell, any of those things.
Invertebrates
Many invertebrates are listed as UK BAP priority species and as Species of Principal Importance (NERC S.41).
Although such species do not receive protection under criminal law their presence is a material planning
consideration, consequently (following Natural England, 2010):
• Regional Planning Bodies and Local Planning Authorities will use the Section 41 list to identify the
species and habitats that should be afforded priority when applying the requirements of the NPPF
(MHCLG, 2019) to promote the “protection and recovery of priority species populations”.
64
• Local Planning Authorities will use it to identify the species and habitats that require specific
consideration in dealing with planning and development control, recognising that under NPPF the
aim of planning decisions should be to avoid minimise impacts to biodiversity.
Of wider relevance to biodiversity assessment is the presence of other rare and scarce invertebrates, of which
potentially there are several thousand in the United Kingdom. These species comprise the majority of
invertebrate diversity and conservation value, and their significance is poorly defined within legislation and
planning policy.
Reptiles
Habitats found on/off site are suitable for common lizards, slow-worms, grass snakes and adders which are
protected under the WCA (1981). These species are listed on schedule 5 and offences are outlined under S9
(1) and S9 (5) and are follows:
• Intentionally, or recklessly, kill or injure any of the above species, and/or;
• Sell, or attempt to sell, any part of the species, alive or dead.
The maximum fine per offence is £5000 and if more than one animal is involved, the fine is £5000 per animal
(WCA 1981, S21). The CRoW amendment contains a provision for a custodial sentence of up to six months
instead of, or in addition to, a fine, along with a lengthy development delay until appropriate mitigation has
been agreed and completed.
The NERC (2006) also lists the above reptiles as a species of ‘principle importance’ under S41 and s40 requires
every public body in the exercising of its functions (in relation S41 species) ‘have regard, so far as is consistent
with the proper exercise of those functions, to the purpose of conserving biodiversity’
Small and medium-sized mammals
Species highlighted for further consideration within this report are European hedgehog, harvest mice, brown
hare and polecat which are all listed as UK Biodiversity Action Plan (UK BAP) priority species, Essex priority
(local BAP) species, and as species of principal importance (section 41) of the NERC Act 2006. Although such
species do not receive protection under criminal law their presence is a material planning consideration.
Consequently:
• Regional Planning Bodies and Local Planning Authorities will use the Section 41 list to identify the
species and habitats that should be afforded priority when applying the requirements of the National
Planning Policy Framework (NPPF) (MHCLG, 2019) to promote the “protection and recovery of
priority species populations”.
Local Planning Authorities will use it to identify the species and habitats that require specific consideration in
dealing with planning and development control, recognising that under NPPF the aim of planning decisions
should be to minimise impacts to biodiversity

Hedgerows
Hedgerows assessed as important under the Wildlife and Landscape criteria of the Hedgerow Regulations 1997
require permission from the local planning authority before they can be removed in whole or in part.

Appendix 3: Detailed Survey Methods
Hedgerows
All hedgerows surrounding the site were assessed under The Hedgerow Regulations (1997) on 21 May 2019.
A total of three hedgerows were subject to survey, detailed survey results for each hedge and their locations
within the site are shown in Appendix 6.
The Hedgerow Regulations 1997
The hedgerows were assessed under the ecological criteria given in the Hedgerow Regulations (HM
Government, 1997). This was to determine whether any of the hedgerows are considered ‘important’ under
the ecological criteria.
To qualify as important under the Hedgerow Regulations 1997, the hedgerow must comply with the following
list of criteria:
• The hedgerow must have a continuous length of or exceeding 20m;
• Has a continuous length of less than 20m, but meets another hedgerow (by intersection or junction)
at each end, and;
• The hedgerow must be over 30 years old.
Apart from the above, to be deemed important a hedgerow must meet one or more of the following criteria:
• The hedgerow marks the boundary of a historic parish or township existing before 1850;
• The hedgerow contains or is within an archaeological feature which is on the Sites and Monuments
Record, or a pre-1600 manor or estate;
• The hedgerow is a part of or associated with a field system predating the Enclosure Acts;
• The hedgerow contains species in part I of Schedule 1; Schedule 5; or Schedule 8 of the Wildlife &
Countryside Act 1981; or various other defined species including certain Red Data Book species;
• The hedgerow is adjacent to a public right of way (not counting an adopted highway) and includes at
least four woody species as defined in Schedule 3 of the regulations plus at least two Associated
Features;
• The hedgerow includes one or more of the following within a 30 m sample area:
o At least seven woody species
o At least six woody species plus at least three Associated Features (see below)
o At least six woody species including a Populus nigra (Black-poplar), Tilia platyphyllos (Large-
leaved Lime), Tilia cordata (Small-leaved Lime) and Sorbus torminalis (Wild Service-tree).
o At least five woody species and at least four Associated Features
The associated features mentioned above, as part of the Hedgerow Regulations 1997, are as follows:
• A bank or wall for at least half the length of the hedgerow;
• A ditch for at least half the length of the hedgerow;
• Gaps over no more than 10% of the length of the hedgerow;
• On average, at least 1 standard tree per 50 m of hedgerow;
67
• At least three woodland species from a list of 57 woodland plants (as defined in Schedule 2 of the
Regulations) within 1m of the hedgerow;
• Connections scoring 4 or more points, where connection with a hedgerow counts as one, a broad-
leaved woodland or pond counts as two; and
• A parallel hedge within 15 m.
Under the Hedgerow Regulations 1997, the removal of any hedgerow to which the Regulations apply is
permitted if it is required for carrying out development for which planning permission has been granted or it
is deemed to have been granted.
Badgers
Surveys were carried out using standard guidelines for classifying badger setts and categorising entrance holes
(Harris et al., 1989; Scottish Badgers, 2018; Natural England, 2009). All areas of the site and wider area were
readily accessible except private residential properties and patches of dense scrub. Detailed results are
provided in Appendix 7, as well as a map showing the location of badger setts.
The survey comprised a detailed systematic walkover survey of the site and known setts. Dense scrub was
present on site and was accessed to a satisfactory degree. The badger signs looked for were:
• Additional holes/setts;
• Prints;
• Badger runs;
• Hairs;
• Latrines;
• Scratching posts, and;
• Snuffle marks.
The number of entrances and levels of use were recorded, and the sett was classified according to the criteria
used in the National Badger Surveys (Harris et al., 1989). The classification criteria are given below:
• Main setts – a large well established, often extensive and in continuous use. There is only one main
sett per social group of badgers. This is where the cubs are most likely to be born.
• Annexe setts – occur in close association with the main sett and are linked to the main sett by clear
well-used paths. If a second litter of cubs are born, they will be reared here.
• Subsidiary setts – these often have 3-5 holes and are normally over 50m from a main sett and are
not linked by clear paths. These setts are not continually active.
• Outlying setts – these usually have 1-3 holes, have small spoil heaps and are sporadically used. Foxes
and rabbits may move in.
An assessment of the activity of each sett was undertaken; the following categories were assigned to the
entrance holes to make this assessment:
• Well-used: Entrances clear of debris and vegetation and are obviously well used.
• Partially-used: Entrances are not in regular use and have debris such as leaves or twigs across the
entrances. These holes could come into regular use with minimal clearance.
68
• Disused: Entrances have not been used for some time, are partially or completely blocked. There may
be a depression in the ground where the hole used to be.
A badger sett is protected by legislation if it “displays signs indicating current use by a badger”. A sett is
therefore protected if such signs remain present (Natural England, 2009). As such, a sett is likely to fall outside
the definition of a sett in the Act if the evidence available indicates that it is not in current use by badgers; e.g.
absence of badger field signs, debris in sett entrances etc.
Bats
Preliminary Assessment
Habitats on and adjacent site were assessed for their suitability to support roosting, foraging and commuting
bats using guidelines issued by the Bat Conservation Trust (Collins, 2016). All potential roosting habitats
(existing buildings and trees) were assigned a level of suitability according to the descriptions outlined in Table
A3.1. Trees and building exteriors were initially assessed from ground level, using binoculars where necessary
to identify potential roost features and bat access points. Building interiors were searched for evidence of
roosting bats using a high-powered torch. Evidence of bat occupation sought included the physical presence
of bats, droppings, urine staining and mammalian fur oil staining.
The site as a whole was also assigned a level of suitability for foraging and commuting bats according to the
descriptions outlined in Table A3.1.
Table A3.1. Assessment of the potential suitability of a proposed development site for roosting, foraging and
commuting bats (Collins, 2016)
Suitability Roosting habitats Commuting and foraging habitats
Negligible Negligible habitat features on site likely to be
used by roosting bats
Negligible habitat features on site likely to be
used by commuting and foraging bats
Low A structure with one or more potential roost
sites that could be used by individual bats
opportunistically but not enough space,
shelter, protection and appropriate conditions
to be used on a regular basis or by larger
numbers of bats
A tree of sufficient size and age to contain
potential roosting features but with none seen
from the ground or features seen with only
very limited roosting potential
Habitat that could be used by small numbers of
commuting bats such as a gappy hedgerow or
unvegetated stream, but isolated, i.e. not very
well connected to the surrounding landscape by
another habitat
Suitable, but isolated habitat that could be used
by small numbers of foraging bats such as a lone
tree (not in a parkland situation) or patch of
scrub
Moderate A structure or tree with one or more potential
roost sites that could be used by bats due to
their size, shelter, protection, conditions and
surrounding habitat but unlikely to support a
roost of high conservation status
Continuous habitat connected to the wider
landscape that could be used by bats for
commuting such as lines of trees and scrub or
linked back gardens
Habitat that is connected to the wider
landscape that could be used by bats for
foraging such as trees, scrub, grassland or water
69
Suitability Roosting habitats Commuting and foraging habitats
High A structure or tree with one or more potential
roost sites that are obviously suitable for use
by larger numbers of bats on a more regular
basis and potentially for longer periods of time
due to their size, shelter, protection,
conditions and surrounding habitat
Continuous, high-quality habitat that is well
connected to the wider landscape that is likely
to be used regularly by commuting bats such as
river valleys, streams, hedgerows, lines of trees
and woodland edge
High-quality habitat that is well-connected to
the wider landscape that is likely used regularly
by foraging bats such as broad-leaved
woodland, tree-lined watercourses and grazed
parkland
Site is close to and connected to known roosts
Emergence/re-entry Surveys
A bat emergence/re-entry survey of the existing semi-detached bungalows on site (at 148-150 Ashingdon
Road) was carried out in accordance with current guidance (Collins, 2016). This recommends one dusk
emergence or dawn re-entry survey, carried out between May-August, for structures assessed as having a ‘low’
suitability to support roosting bats.
A dusk emergence survey was therefore conducted on 15 August 2019, commencing 15 minutes before sunset
and continuing until approximately 1.5 hours after sunset. The survey was carried out under appropriate
weather conditions (avoiding strong winds, cold temperatures and heavy rainfall).
Three surveyors maintained static positions around the building, focusing their attention on features that could
potentially be utilised by roosting bats and watching closely for any emergence, while also recording bat
activity incidentally observed in the immediate surroundings.
Surveyors used Batlogger and Batbox Duet bat detectors with Edirol/Tascam digital recorders to record bat
activity. Calls were subsequently analysed using Kaleidoscope and BatExplorer computer software.
Activity Surveys
The site was assessed as having low suitability for foraging and commuting bats therefore a suite of further
activity surveys were required. The following surveys were recommended in line with published guidelines
(Collins, 2016), see Table A3.2.
Table A3.2. Guidelines on the number of bat activity surveys recommended to achieve a reasonable survey effort in
relation to a site with low habitat suitability, adapted from Collins 2016.
Survey type Low suitability habitat for bats
Transect surveys One survey visit per season (spring – April/May, summer – June/July/August, autumn
– September/October) in appropriate weather conditions for bats
Automated surveys One location per transect, data to be collected on five consecutive nights per season
in appropriate weather conditions for bats
70
Transect surveys provide qualitative descriptive data which describes how bats use the site. A transect route
(Appendix 8) was designed to cover all the best habitats for bats on and adjacent to the site. Given the extent
and range of habitats present, one transect route was considered sufficient to sample the site.
The transect route was walked at a steady pace (so the sampling area is the same per unit time), and
supplemented by spot counts, where surveyors remained stationary for 5 minutes at locations along the route
selected to represent the different habitats in the survey area. The transect start point and direction of travel
was randomised for each survey to overcome the potential for results to be biased by systematic differences
in the timing with which each habitat feature was sampled across the series of surveys.
Surveyors recorded observations of bats such as likely species, numbers, flight direction, flight height,
behaviour (e.g. foraging or commuting), appearance and relative speed. Surveyors used an Echo Meter touch
2 Pro to record echolocation calls, which were subsequently analysed using Kaleidoscope computer software.
Three surveys were undertaken in 2019, one in May, one in July and one in September 2019, to provide
coverage across the bat active season. All surveys were undertaken at dusk, when bat activity tends to be the
highest, and in appropriate weather conditions for bats (no heavy rain, cold temperatures or high winds). In
accordance with guidance, all surveys commenced at sunset and lasted until two hours after sunset. Results
are reported in Appendix 8
Automated Surveys
Automated static detectors provide quantitative data over longer periods of time useful for assessing the
species assemblage in an area and the temporal changes in bat activity.
Two static detectors per transect were set up at different monitoring points and used to record bat activity
within the habitats on site for at least five consecutive nights per season, in accordance with current guidance.
Sampling was undertaken in May, July and September 2019. Survey dates were selected when the predicted
weather forecast indicated suitable weather conditions for foraging and commuting bats (i.e. air temperature
above 10°C, no strong winds and no rain).
Anabat Express and Anabat Swift static bat detectors were used to record bat echolocation calls. The units
were set up to continuously record from 30 minutes before sunset until 30 minutes after sunrise. All recordings
were stored on memory cards and analysed using computer software programs Analook and Kaleidoscope.
Echolocation calls were identified down to species or genus level depending on the type of bat encountered
(often it is not possible to reliably identify species belonging to the genus Myotis, Plecotus and Nyctalus) and
the quality of the recording.
The analysed data was then standardised to account for differences in night length and the number of nights
over which activity was sampled per season. This was achieved by following procedure:
• dividing the total number of passes recorded per season (defined as a maximum 15 second bat
recording) by the number of recording nights, to provide the number of passes per night
• then, dividing the number of passes per night by the night length, to provide the number of passes per
night hour
71
• finally, multiplying the number of passes per night hour by the mean night length over the sampling
period, to provide the standardised number of passes per night
Birds
Breeding Bird Surveys
SES conducted three breeding bird survey visits during the 2019 bird breeding season, one per month from
April to June. The survey area included the whole of the study area and adjacent areas that could be surveyed
from within the site, generally covering a buffer perimeter of 10-20m. Thus, adjacent field boundaries and
other potential bird nesting habitats where birds using the site during the breeding season may nest, and vice
versa were generally also included. A transect was walked slowly pausing to record birds heard and observed,
covering all areas of the study area within 25m, and route directions were varied between survey visits. Birds
flying over and not using the site or surrounding area were recorded separately. All bird locations and
behaviour were mapped onto photocopied OS maps (1:5000 scale) using the standard CBC notation.
All survey visits were undertaken during the morning after the dawn period when bird singing intensity tends
to be high but stable (Bibby et al. 2000).
Field maps were analysed to determine probable breeding bird registrations relating to different territories
and to judge which birds are using the area for breeding or for other activities such as foraging. A probable or
definite territory is defined as a cluster of registrations of singing or displaying individuals from more than one
visit, or one or more registrations of the following breeding behaviour: disturbance displaying, interspecific
aggressive interaction, repetitively alarming, carrying food, nest material or faecal sacs, or if active nests or
young were found.
If a singing bird is recorded on just one visit or sight observations of birds are recorded in the same area on
more than one visit and are not likely to be associated with any other recorded territories, these are assigned
as possible territories. For birds that do not sing, such as many waterfowl, birds present at a location in suitable
breeding territory on at least two visits are assigned to probable territories. Presence of such species in suitable
breeding habitat on a single visit is assigned to possible territories unless the possibility of nesting is considered
negligible by the observer.
This process is open to subjectivity in interpretation except where active nests are located. Therefore, these
territories are classed as putative and their mapped locations indicate the ‘centre’ of a territory and not
necessarily the nesting location. The maps were analysed to determine the number of probable and possible
territories or pairs of each species present.
Great Crested Newts
HSI Survey
Aquatic habitats were assessed for their suitability to support breeding GCN (as well as other amphibians)
using the Habitat Suitability Index (HSI). This method was developed by Oldham et al. (2000) and provides a
numerical index, between 1 and 0, based on a number of factors which influence great crested newt presence:
72
• Geographic locality
• Pond area
• Permanence
• Water quality
• Shade
• Waterfowl presence
• Fish presence
• Pond count within 1km2 of survey pond
• Terrestrial habitat quality
• Macrophyte cover
The data regarding each factor is collected in the field at each pond and also by using maps, this is then
converted into SI scores on a scale of 0.1 -1.0. The HSI is calculated as a geometric mean of the 10 suitability
indices (SI) as indicated below:
HSI = (SI1 x SI2 x SI3 x SI4 x SI5 x SI6 x SI7 x SI8 x SI9 x SI10) 1/10
On the index, 0 indicates unsuitable habitat, while 1 represents optimal habitat. Lee Brady developed a system
of using HSI scores to define ponds suitability for great crested newts on a categorical scale during a study
undertaken in south-east England in which 248 ponds were surveyed for GCN using standard methods and
also subjected to an HSI. The results of this study show that as the HSI score increases, the proportion of ponds
occupied also increases, as summarised below:
Table A3.3. HSI score categories (Oldham et al., 2000) and predicated probability of GCN presence
HSI score Pond suitability Predicted presence of GCN (% of
ponds occupied n=248)
< 0.5 Poor 0.03
0.5 – 0.59 Below average 0.2
0.6 – 0.69 Average 0.55
0.7 – 0.79 Good 0.79
> 0.8 Excellent
Presence / Absence Pond Surveys
Eight ponds within 500m of the site were surveyed between mid-March and mid-June 2019. Surveys were
undertaken during suitable conditions i.e. when the ambient air temperature exceeded 5°C, with little/no wind
and no rain.
The surveys followed recommended methods (English Nature, 2001). To determine the presence or likely
absence of GCN, four individual survey visits were carried out, at least two of these falling within the peak
survey season of mid-April to mid-May. On each survey occasion, a minimum of three different techniques
(bottle trapping, torching, egg searching, terrestrial searching) were used where possible. A summary of each
is provided below:
73
Bottle Trapping
Bottle traps were deployed in the waterbodies in the evening at densities of one trap per 2m of shoreline
(where feasible) and left overnight for inspection in the morning. Traps were partially submerged in the water
leaving an air bubble in the bottle and secured by a cane marked with a high visibility tape to ensure relocation
the following day. Care was taken to ensure that trapping did not occur during excessively warm weather,
when the temperature inside the trap could rise considerably, reducing oxygen levels and potentially
suffocating the newts.
Torching
Torching involved searching the waterbody after dusk using high-powered torches to scan the margins and
potential display areas for newts. The perimeter of the pond was walked slowly recording any newts observed.
Egg Searching
Newts lay single eggs on the leaves of aquatic plants or other suitable pliable material, after which the material
is folded over the egg to protect it. GCN eggs can be distinguished from those of the other newts by their size,
shape and colour. Submerged vegetation was examined for newt eggs and folded leaves gently opened to
check for eggs.
Terrestrial Searching
Great crested newts may rest under refuges such as logs, bark, rocks, and debris (discarded furniture, etc).
Items such as this within the vicinity of the ponds were lifted to search underneath. It should be noted that
this is considered an inefficient method and is best used as an additional technique.
Population Size Class Assessment
Two further surveys were carried out at one pond (P12) where GCN were confirmed to be present. These
further surveys followed the same methodology as outlined above, with at least one additional visit being
undertaken during the peak survey season of mid-April to mid-May, in accordance with current guidance.
The maximum adult count per night gained through torch survey or bottle-trapping (the peak count) was used
to determine the population size class, as indicated in the table below.
Table A3.4. Population class size assessment.
Population Class Peak Count
Small <10
Medium 11-100
Large >100
Reptiles
Artificial refuges (0.5m x 0.5m felt squares) were laid in suitable habitat, using the surveyor’s professional
judgement. Artificial refuges were used to observe reptiles basking or taking refuge, these were laid in
transects and left for seven days to settle before the survey commenced. Guidance recommends laying mats
74
at density of 10p/ha of suitable habitat (Froglife, 1999), however in this case a larger number of mats (120 for
approximately 2.5ha of suitable habitat) were laid to match previous survey effort and foster comparability of
results.
Visits for the presence/likely absence survey were undertaken during ‘suitable’ days for reptile activity; a
‘suitable’ survey day is determined by the weather, with temperature being the pre-eminent factor. Reptile
surveys conducted between 10 and 17°C have the most chance of success. The key months for reptile surveys
are April, May and September with April and May being advantageous because it is reptile mating season,
which means they will be more obvious and less wary of observers. Also, the temperatures are generally lower
during these months and as such it will take longer for the reptiles to warm up so they must spend more time
basking. During the warmer summer months animals will have to spend less time basking due to the increase
in ambient temperature, thus reptile survey visits will be conducted earlier in the day during the hotter
summer months. However, the temperature on the day of the visit will ultimately determine what time the
survey takes place.
As presence was detected a categorical population assessment was carried out with the largest count within
the first seven visits indicating the category of the recorded reptile species. This count was adjusted to
determine the population class due to enhanced survey effort. The table below details the assessment
categories:
Table A3.5. Froglife reptile population assessment.
Species Low Population Good Population Exceptional Population
Common Lizard <5 5-20 >20
Slow-Worms <5 5-20 >20
Grass Snake <5 5-10 >10
Adder <5 5-10 >10

Appendix 4: CIEEM EcIA Methods
Ecological features are evaluated and assessed with due consideration for the Chartered Institute of Ecology
and Environmental Management (CIEEM) Guidelines for Ecological Impact Assessment (EcIA) (CIEEM, 2016;
updated 2018). For clarity, the evaluation and assessment process adopted within this report is set out below.
Establishing potentially important ecological features
Potentially important ecological features of relevance to the development are determined in accordance with
current CIEEM guidelines. Table below sets out a non-exhaustive list of ecological features that are typically
considered, along with key examples:
Table A4.1. Examples of potentially important ecological features.
Potentially important ecological feature Typical examples
Statutory designated sites SSSIs, SACs, SPAs, Ramsar sites, LNRs, NNRs
Non-statutory designated sites LWSs, CWSs
Protected species European protected species (e.g. GCN, bats)
International, National or local priority habitats S41 priority habitats and species; Annex I Habitats
Notable species or sub-species Individual red-listed species
Notable or large population or assemblage of species Diverse bird assemblage; exceptional numbers of
common amphibians
Novel or locally distinct assemblage of species
Diverse non-native floral community on a brownfield site;
populations of individual species showing distinct physical
variation
Habitats which form diverse mosaics, create important
connection and/or have synergistic attributes;
Brownfield habitat mosaics; riparian habitat corridors;
hedgerow network utilised by an important bat
population
Habitats of potential importance (with regard to restoring
or creating habitats to S41 priority or SSSI quality) Previous Ancient Woodland (PAWs) sites
Habitats of secondary or supportive importance (which
safeguard important habitats, or which support important
populations of species)
Scrub habitats buffering calcareous grassland from
agricultural improvement; pasture regularly utilised by
bird populations for which an SPA is designated
Establishing likely Zone of Influence (ZoI)
For the purposes of this assessment, the site is considered to be inside the ‘zone of influence’ of:
• Internationally important designations within 22km of the site boundary.
• Nationally important designations within 5km of the site boundary.
• Locally important designations within 2km of the site boundary.
• Non-statutory designations within 2km of the site boundary.
The arbitrary distances identified set out above considered sufficient for identifying the majority of
designations which may be affected by the proposals. However, it is acknowledged that in certain
circumstances effects beyond these distances are possible and should be considered as far as is reasonably
practicable to do so.
76
It should also be noted that certain ecological features have smaller ‘zones of influence’ than those mentioned
above. For such features the appropriate zone of influence is described and justified as appropriate within the
report, depending on their respective sensitivity to an environmental change.
The results of professionally accredited or published scientific studies have been used and referenced, where
available, to establish the spatial and temporal limits of the biophysical changes likely to be caused by specific
activities and to justify decisions about the zone of influence.
Determining importance of ecological features
In determining the importance of ecological features, a range of guidelines and reference materials have been
utilised, including:
• Criteria against which statutory and non-statutory nature conservation designations are selected (e.g.
SSSI designation criteria; LWS selection criteria).
• Definitions for national and priority habitats.
• Publications and guidelines against which to establish the importance of particular populations or
assemblages of species groups (e.g. Wray et al for evaluating bat populations and roosts; ISIS for
assessing conservation interest of invertebrate assemblages).
• Publications describing the conservation status of individual species (e.g. Red-data books).
• The Hedgerows Regulations to assess the importance of hedgerows.
• National, regional and local species Atlases.
• Species/group population trends.
It should be noted that the legal protection which some species and their habitats receive are considered
separately from ‘importance’ within this assessment as not all legally protected species are necessarily rare
(e.g. common pipistrelle bat). Legal issues and the appropriate mechanism for dealing with any such constraint
are addressed in the report.
It should also be noted that the social, community, economic or multifunctional importance attributed to
ecological features are not assessed as they fall outside the scope of this assessment.
Geographic frame of reference
In assigning importance to an ecological resource the following geographic frames of reference are used:
• International;
• National (i.e. England);
• Regional (South East);
• County (Essex);
• District (Rochford District);
• Local or Parish (Rochford); and
• Within Site or zone of influence only
The size, conservation status and the quality of features or species are all relevant in determining value.
Furthermore, the value of a species and / or habitat may vary depending on its geographical location.
77
Characterising effects and any significant effects of the proposed project or occupation are characterised using
the following terminology:
• Direct or indirect
• Beneficial or adverse
• Magnitude and/or extent
• Duration
• Reversibility
• Timing and frequency
Impacts have been assessed using the Mitigation Hierarchy, which forms the key principles of Ecological Impact
Assessment (EcIA):
• Avoidance – seeking options to avoid harm to ecological features;
• Mitigation – seeking options to avoid or minimise adverse effects;
• Compensation – offsetting adverse effects through appropriate compensatory measures;
• Enhancements – seeking to provide net benefits for biodiversity.
Determining ecologically significant effects
An ecologically significant effect is defined as an effect (adverse or beneficial) on the integrity of a defined
designated site or ecosystem and/or the conservation status of habitats or species within a given geographical
area.
The importance of any feature that will be significantly affected is then used to identify the geographical scale
at which the impact is significant. This value relates directly to the consequences, in terms of legislation, policy
and/or development control at the appropriate level. So, a significant adverse effect on a feature’s importance
at one level would be likely to trigger related planning policies and, if permissible at all, generate the need for
development control mechanisms, such as planning conditions or legal obligations, as described in those
policies.
If an effect is found not to be significant at the level at which the resource or feature has been valued, it may
be significant at a more local level. Significant effects on features of ecological importance will be mitigated
(or compensated for) in accordance with guidance derived from policies applied at the scale relevant to the
value of the feature or resource. The scale is derived from the interaction of the feature sensitivity and
magnitude of impact.
