2 Introduction
2.1 Background
agb Environmental was commissioned by Rand Brothers, to undertake an ecological survey
at Land at Royston Road, Barkway, Hertfordshire SG8 8BX.
This report contains the findings of a Phase 1 Habitat Survey to identify the potential for
presence of species protected under European Legislation (Conservation of Habitats and
Species Regulations 2010, as amended), UK legislation (Wildlife and Countryside Act 1981;
Protection of Badgers Act 1992), and other priority species and habitats which are a
consideration under the National Planning Policy Framework (NPPF).
The Natural Environment and Rural Communities (NERC) Act 2006, under Section 41, lists
Species of Principal Importance for Conservation of biodiversity in England (SPIE species).
Protected and UK SPIE species are a material consideration for individual planning consents
under the NPPF, which promotes the enhancement of natural and local environments through
planning, and encourages a move towards achieving net gains for biodiversity where possible
(DCLG, 2012).
The site survey is supported by a desk study, including consultation with the Herts
Environmental Records Centre (HERC), to identify the presence of statutory and non-statutory
designated wildlife sites, and any protected species, which could be impacted by development
of the site.
2.2 Proposed Development
Proposals are likely to include residential development of the site, with associated
infrastructure and soft landscaping.
2.3 Scope of survey
This Phase 1 Habitat Survey is based on a single site survey, and provides an overview of the
likelihood of protected species occurring on the site: Where no evidence is found, this does
not mean that species are not present, or using the site. Further surveys are only
recommended if there is a significant likelihood that protected species may be present and
impacted by the proposed development, based on the suitability of the habitat and any direct
evidence.
This Phase 1 Habitat Survey does not constitute a full botanical survey or a Phase 2 pre-
construction survey for Japanese knotweed Fallopia japonica.

3 Survey Methodology
3.1 Habitat Survey
The survey involved a site visit to record and map habitat types and ecological features on the
site. The survey was undertaken in accordance with Guidelines for Preliminary Ecological
Assessment produced by the Chartered Institute of Ecology and Environmental Management
(CIEEM, 2015), and the general principles and methods outlined in the Handbook for Phase 1
Habitat Survey (JNCC 2010). Features of interest were identified as target notes on the Phase
1 Habitat Map (Appendix B).
The potential for presence of protected species was assessed as follows:
Amphibians - Known ponds within 500m of the site (unless ecologically separated by
significant barriers) were addressed for potential to support breeding protected amphibians,
such as great crested newts or toads.
Bats - Trees adjacent to the site boundary were assessed from the ground for potential to
support roosting bats. Habitat was also assessed for foraging and commuting potential, aided
by aerial photographs of the surrounding landscape.
Dormice - Hedges were assessed for potential to support dormice: Structure, connectivity and
a range of food sources throughout the active dormouse season.
Reptiles - The presence of suitable reptile habitat was assessed according to the criteria
described in the Herpetofauna Workers’ Manual (Gent and Gibson 1998) and Froglife
guidelines (Froglife 1999).
Invertebrates - The site was surveyed for high quality aquatic, deadwood or other habitats
which could be used by significant assemblages of invertebrates, or by invertebrate species
identified in the desk study.
Flora and habitats - Habitats and dominant plant species which were identifiable at the time
of the survey were recorded, including Wildlife and Countryside Act Schedule 9 invasive plant
species, such as Japanese knotweed and giant hogweed Heracleum mantegazzianum.
Water voles and otters – Any water bodies within impact distance of the site were assessed
for potential to support water voles and otters.
Badgers - A visual assessment for setts, hair, latrines, prints, foraging disturbance or other
signs of badger activity was undertaken within, and directly adjacent to, the site boundary.
Birds - A visual survey of bird activity and suitable nesting habitat was carried out, to determine
if any areas would be suitable for WCA Schedule 1 birds, Birds of Conservation Concern
(BoCC), SPIE or other common and widespread nesting birds.
Adjacent habitat - Aerial photographs, maps and field observation were used to identify
habitats in the wider landscape which could be impacted by development of the site.

3.2 Desk Study
Data was obtained from the following sources:
3.2.1 Herts Environmental Records Centre (HERC)
Records were provided on 27th April 2015, of protected species and Local Wildlife Sites (LWS)
within a 2km radius of the site.
3.2.2 Local Biodiversity Action Plan (BAP)
The site was covered by the Local BAP for Hertfordshire.
3.2.3 Statutory designated sites
The Multi-Agency Geographic Information for the Countryside (MAGIC), was accessed (8th
May 2015), to identify the presence of statutory designated sites within a 2km radius. The
search radius was extended to 7km for European designated sites (Special Areas of
Conservation (SACs), Special Protection Areas (SPAs) and Ramsar sites), where the potential
risk of impact to interest features of such sites may extend over a wider area.
3.3 Surveyor Details
The site survey was undertaken by Odette Robson BSc (Hons) PhD MCIEEM Principal
Ecologist at agb Environmental, on the 29th April 2015. During the survey, the temperature
was 10°C; there was a breeze (Beaufort scale 5), 90% cloud cover and occasional rain
showers, though good visibility.
The surveyor is a full member of the Chartered Institute of Ecology & Environmental
Management (MCIEEM), subject to the CIEEM Professional Code of Conduct and licensed by
Natural England to survey for great crested newts (WML-CL09; Level 2), bats (WML-CL18;
Level 2) and dormice (WML-CL10a; Level 1).

4 Results and Discussion
4.1 Site and Habitat Description
The site was located on the northern edge of the village of Barkway in North Hertfordshire.
Directly adjacent to the western boundary was Royston Road, with arable farmland and
residential properties beyond. To the north and east, a bridleway separated the site from
grassland (grazed horse pasture to the north and rough grassland to the east). The southern
site boundary was unmarked, crossing the arable field.
There were no significant waterbodies or watercourses in the local landscape, however, a
large network of small ponds was present. Nine ponds were marked on maps within 500m of
the site, of which the nearest to the site was approximately 120m to the south. This pond was
dry at the time of survey. The remaining eight ponds were all more than 250m from the site.
There were a number of small woodlands in the area, within the predominantly agricultural
landscape, including three ancient woodlands within 2km (to the south-east and west).
The site itself was an arable field, currently uncropped but with a high (40%) cover of volunteer
oil seed rape and arable weeds. The boundaries to the north, east and west were managed
hedgerows with an associated 1-2 metre grass and ruderal field margin.

4.3 Desk Study
The site itself was not situated within a designated wildlife area, and was listed within the
Hertfordshire Ecological Network as MO6788: No known habitat; medium priority for habitat
creation, with the target habitat for creation being chalk grassland.
There were no statutory sites, designated for wildlife, within 2km of the site, and no European
sites, designated for wildlife, within 7km.
Fifteen Local Wildlife Sites (LWS) were identified within 2km of the proposed site (provided by
HERC), of which those within 1km of the site midpoint are listed in Table 4.1. Barkway Chalk
Pit, a Herts and Middlesex Wildlife Trust site, is also a Regionally Important
Geological/Geomorphological Site (RIGS - non-statutory earth science site).

4.4 Potential for Protected Species
The site was assessed to identify whether proposed works within the site boundary could
impact on protected or locally rare species, either on the site or within the local area.
4.4.1 Habitats and Species
No protected, BAP, SPIE or locally important floral species were recorded at the site during
the survey, which was carried out at a suitable time of year for botanical surveys, when broad
species assemblages and habitat character could be assessed, and many species were
identifiable to species level.
agb Environmental Ltd
P2384.1.1 Phase 1 Habitat Survey 19 May 2015 Land at Royston Road, Barkway, SG8 8BX Page 15 of 26
Arable weeds within the cropped area included common groundsel Senecio vulgaris,
scentless mayweed Tripleurospermum inodorum, sowthistle Sonchus spp., knotgrass
Polygonum aviculare, wild radish Raphanus raphanistrum, cut-leaved crane's-bill Geranium
dissectum, creeping thistle Cirsium arvense, field bindweed Convolvulus arvensis, nipplewort
Lapsana communis, spear thistle Cirsium vulgare, curly dock Rumex crispus, common field-
speedwell Veronica persica, red deadnettle Lamium purpureum, fat hen Chenopodium album,
cleavers, poppy Papaver spp, and sun spurge Euphorbia helioscopia.
No rare or uncommon arable weeds were recorded, such as Euphorbia exigua or the
uncommon Fumaria species which have been recorded locally. The timing of the survey was
appropriate to be able to identify these arable weed species.
The hedges at TN2, TN3 and TN5 were species-poor and lacking additional features such as
ditches or banks. The hedge at TN4 was defunct, with a number of non-native, introduced
species, forming the curtilage of a residential property (TN4). None of the site boundary
hedges would be classified as ‘important’ under the Hedgerow Regulations (1997).
4.4.2 Bats
Roosting Bats
HERC provided records of four species of bats within 2km: Three species were identified within
the same km grid square as the site (brown long-eared bat, Natterer’s bat and pipistrelle).
There were no roosting opportunities on, or adjacent to, the site. No buildings or structures on
the site, and no trees of sufficient maturity to provide potential roosting features.
Foraging and Commuting Bats
The site was of low quality for foraging bats with no mature trees, large extent of bare ground
and limited vegetation that would support significant quantities of insects. Native boundary
hedges could provide some foraging opportunity, but were managed to a low height, so would
provide little shelter for commuting bats.
If the hedges can be retained within the scheme, and lighting directed away from the hedge
boundaries, then any commuting or foraging bats would not be impacted by development of
the site.
No further surveys for bats are recommended.
4.4.3 Reptiles
No reptile records were provided by HERC. Habitats on the site were sub-optimal for reptile
species, such as slow worm, common lizard and grass snake, due to lack of ground vegetation,
and no hibernation and refuge opportunities.
No further survey or precautions are recommended.
4.4.4 Amphibians (great crested newt and common toad)
HERC provided three records of great crested newts from approximately 0.5km to the south-
west of the site 2004; and a toad record over 500m from the site.
There were no water bodies within the site boundary, and the nearest known pond was
approximately 120m to the south of the site, which was dry at the time of the survey. A further
agb Environmental Ltd
P2384.1.1 Phase 1 Habitat Survey 19 May 2015 Land at Royston Road, Barkway, SG8 8BX Page 16 of 26
eight ponds were marked on available maps within 500m of the site: All were beyond 250m of
the site boundary, with limited ecological connectivity due to intervening infrastructure.
There were no hibernation, foraging or refuge opportunities at the site, which had poor
terrestrial habitat for amphibians.
Potential for great crested newts or toads to use the site was negligible, and no further surveys
or precautions are recommended.
4.4.5 Birds
A large number of bird records from the local area were provided by HERC, of which a number
were listed on Schedule 1 of the WCA, BAP/SPIE species, and Birds of Conservation Concern.
The site could provide nesting habitat for small common birds in the hedgerows, and SPIE or
Local BAP species, such as skylark and grey partridge, at times of the year when the crop
height/composition is suitable. Yellowhammer, corn bunting, linnet and tree sparrow could use
the hedge boundary habitat, under appropriate management.
Removal of any hedgerow sections, or ground clearance, should be undertaken outside the
nesting bird season, or preceded by a nesting bird survey to confirm presence/absence of
nests immediately prior to works being undertaken (within three days of the start of the works).
The main bird nesting season is March to August inclusive.
4.4.6 Badger
Badgers have been recorded in the local area. HERC provided a record within 1km of the site,
from 1997. However, no evidence of badger activity or setts (active or inactive) was identified
on the site, and due to the open nature there is negligible risk that badgers would use the area
for sett creation. A mammal push-through at the northern boundary hedge was likely to be
used by fox. Badgers could potentially forage within, or commute through, the site.
Precautions, detailed in Section 5, should be implemented to protect badgers and other
mammals during the construction phase.
4.4.7 Otter and Water Vole
HERC did not hold records for otters or water vole within 2km of the site. There were no
significant water bodies within impact distance of the site. No further surveys or precautions
are necessary.
4.4.8 Dormice
HERC provided a single dormouse record from 1985, approximately 2km to the east. The
hedgerows surrounding the site (to north, west and east) lacked the structure to support
dormice. Hedges were well-managed, with frequent gaps, no tree standards, and with limited
connectivity to off-site wooded areas which could support a dormouse population. Potential for
dormice to use boundary hedgerows was very low, and no further survey or precautions are
recommended.
4.4.9 Hedgehogs, Hares, or Other Protected, BAP or Rare Species
A hare was recorded on the site during the survey, and there was evidence that hares had
frequently grazed the brassicas growing on the site. However, open arable and grassland
fields were widespread adjacent to the site and in the wider landscape. Loss of this arable site,
on the edge of the village and bordered by a road to the west, is unlikely to fragment habitat

used by hares, or to impact individual hares, or the local conversation status of hares. No
further survey or precaution is necessary.
There was low potential for hedgehogs to use the site margins, at the hedgerow bases and
field margins. There were no hibernation or refuge areas (such as wood piles) for hedgehogs,
so clearance of the site is unlikely to harm individuals. On completion, the development is likely
to include garden habitat suitable for hedgehogs. If hedgehog links under any solid garden
fences are created, allowing movement of hedgehogs through the area, the site will remain
suitable for hedgehogs on completion.
4.4.10 Invertebrates
There was no aquatic or deadwood habitat at the site that could support a diverse assemblage
of invertebrate species.
Vegetation on the site was limited and unlikely to support the Lepidoptera species listed in the
HERC data search.
4.4.11 Impact on Designated Wildlife Sites
There are no statutory wildlife sites within 2km and no European designated statutory wildlife
sites within 7km. Fifteen non-statutory Local Wildlife Sites were present within 2km, including
three ancient woodland sites, and a disused chalk pit. Direct impact on any locally designated
sites is unlikely, due to the distance and intervening infrastructure. Indirect impact from
increased visitor numbers are also unlikely, due to the large number of recreational open
space opportunities and footpaths closer to the proposed development site.
4.5 Limitations and Assumptions
The baseline conditions reported and assessed in this document represent those identified at
the time of the survey on 29th April 2015. Although a reasonable assessment of habitats
present can be made during a single walkover survey, seasonal variations are not observed.
All areas of the site were accessible on the day of the survey.

5 Recommendations
5.1 Key Recommendations and Avoidance/Precautionary Methods
Clearance of vegetation, including the main cropped area, and any sections of
hedgerows, should be carried out outside the nesting bird season (March to August
inclusive), or preceded by a nesting bird survey to avoid infringing legislation which
protects all nesting birds (WCA 1981).
To protect any mammals (such as hare, hedgehogs or badgers) in the area, any
foundations, holes or deep pits which are left overnight should have a secured plank,
or other means of escape made available.
Any security or task lighting should be directed away from boundary hedges, to
maintain dark corridors which could be used by bats. PIR lights should be sensitive to
large moving objects only. Any street-lighting at the boundaries should be low level,
with cowls of baffles to avoid light-spill.
Any barriers, such as close-board garden fence, should have hedgehog links at
ground-level (gaps approximately 10cm x 10cm, every 10m).
If these recommendations are carried out, then potential impact of the proposed development
on local biodiversity would be minimal. The site could be enhanced for wildlife if the following
additional recommendations are implemented.
5.2 Enhancement Recommendations
These recommendations will enhance the value of the site for wildlife, and will help towards
Local BAP targets and enhancement, as encouraged through the NPPF.
1) Native fruit and berry bearing species such as hazel Corylus avellana, apple Malus
spp., hawthorn Crataegus monogyna, blackthorn Prunus spinosa, guelder rose
Viburnum opulus and spindle Euonymus europaeus could be included along within the
boundary hedges to the north, west and east, where there are gaps. New hedge-
planting could be considered for the southern boundary. This would enhance ecological
connectivity around the site and provide foraging and refuge opportunities for birds,
small mammals and other wildlife.
2) Tree standards, which could include oak Quercus robur and field maple Acer
campestre, could be planted within the existing hedge, and any new hedge-planting to
the south.
3) A wildflower grassland area could be included to provide suitable habitat for reptiles,
and to encourage invertebrates to use the site. This should be planted with native chalk
grassland species, to contribute to BAP targets and as suggested by the Hertfordshire
Ecological Network project.
4) Bird boxes could be provided on fences, sheds and new homes. These should be sited
to avoid direct sunlight (not directly south-facing), prevailing wind and the heaviest rain.
Areas inaccessible to cats should be used:
o A smaller, open-fronted box, made to BTO dimensions (for song thrush, robin
and spotted flycatcher).

o Three hole-box type bird boxes with 32mm holes for house sparrows – which
should be located in a group of three boxes for this colonial nesting species.
Ideally, these should be located in a sheltered, less disturbed part of the site,
within scrub or trees and close to the site boundary.

6 Conclusion No further protected species surveys are recommended.
If the precautionary clearance methods recommended to protect nesting birds, commuting
bats at the boundary, and nocturnal mammals (detailed in Section 5) are carried out,
development of the site can proceed with minimal impact on any protected, SPIE or locally
rare species within the area (individuals, or the local conservation status).
If some, or all, of the additional recommendations (Section 5.2) are implemented, the site could
be enhanced for local wildlife, post completion.

Appendix A – Legislation & Planning Policy National Legislation
Conservation of Habitat and Species Regulations
The Conservation of Habitats and Species Regulations transpose Council Directive
92/43/EEC on the Conservation of Natural Habitats and Wild Flora and Fauna (Habitats
Directive) into English law, making it an offence to deliberately capture, kill or disturb wild
animals listed under Schedule 2 of the Regulations. It is also an offence to damage or destroy
a breeding site or resting place of such an animal (even if the animal is not present at the time).
Wildlife & Countryside Act
The Wildlife and Countryside Act 1981, as amended by the Countryside and Rights of Way
Act (CRoW) 2000 and the Natural Environment and Rural Communities Act (NERC) 2006,
consolidates and amends existing national legislation to implement the Convention on the
Conservation of European Wildlife and Natural Habitats (Bern Convention) and Council
Directive 79/409/EEC on the Conservation of Wild Birds (Birds Directive), making it an offence
to:
Intentionally kill, injure or take any wild bird or their eggs or nests (with certain
exceptions) and disturb any bird species listed under Schedule 1 to the Act, or its
dependent young while it is nesting;
Intentionally kill, injure or take any wild animal listed under Schedule 5 to the Act;
intentionally or recklessly damage, destroy or obstruct any place used for shelter or
protection by any wild animal listed under Schedule 5 to the Act; intentionally or
recklessly disturb certain Schedule 5 animal species while they occupy a place used
for shelter or protection;
Pick or uproot any wild plant listed under Schedule 8 of the Act.
Sites of Special Scientific Interest (SSSI) are designated under this Act.
Special Protection Areas (SPA) are strictly protected sites, designated under the Birds
Directive, for rare and vulnerable birds and for regularly occurring migratory species.
Natural Environment & Rural Communities Act
The NERC Act amends the CRoW Act, by further extending the requirement to have regard
for biodiversity to all public authorities, which includes local authorities and local planning
authorities and requires that the Secretary of State consults Natural England (NE) in the
publication of the list of living organisms and habitat types deemed to be of principal
importance in conserving biodiversity.
National Planning Policy Framework (NPPF)
The NPPF sets out current government policy on biodiversity and nature conservation and
places a duty on planners to make material consideration to the effect of a development on
legally protected species when considering planning applications. NPPF also promotes
sustainable development by ensuring that developments take account of the role and value of
biodiversity and that it is conserved and enhanced within a development
agb Environmental Ltd
P2384.1.1 Phase 1 Habitat Survey 19 May 2015 Land at Royston Road, Barkway, SG8 8BX Page 23 of 26
NPPF replaced PPS9 in April 2012. NPFF works is considered in conjunction with
Government Circular 06/2005 ‘Biodiversity and Geological Conservation - Statutory
Obligations and Their Impact within the Planning System.’
Wild Mammals (Protection) Act, (1996)
This Act states it is an offence to intentionally cause all wild mammals’ unnecessary suffering
by certain methods, including crushing and asphyxiation. This includes common mammals
such as red fox.
National Planning Policy
Biodiversity Action Plans
The UK Biodiversity Action Plan (UKBAP) (Anon, 1995) was organised to fulfil the Rio
Convention on Biological Diversity in 1992, to which the UK is a signatory. As a result of new
drivers and requirements, the 'UK Post-2010 Biodiversity Framework', published in July 2012,
has succeeded the UK BAP. In particular, due to devolution and the creation of country-level
biodiversity strategies, much of the work previously carried out under the UK BAP is now
focussed at a country level.
The UK BAP lists of priority species and habitats are still valuable reference sources. Notably,
they have been used to help draw up statutory lists of priority species and habitats as required
under Section 41 of the NERC act.
UK Post-2010 Biodiversity Framework
The UK Post-2010 Biodiversity Framework (2012) was produced in response to a change in
strategic thinking following the publication of the Convention of Biological Diversity’s Strategic
Plan for Biodiversity 2011–2020. The Strategic Plan consists of 20 new biodiversity targets for
2020, termed the ‘Aichi biodiversity targets’ and the launch of the new EU Biodiversity Strategy
in May 2011.
The framework sets a structure for action across the UK between now and 2020, including a
shared vision and priorities for UK-scale activities to help deliver the Aichi targets and the EU
Biodiversity Strategy. A major commitment by Parties to the Convention of Biological Diversity
is to produce a National Biodiversity Strategy and/or Action Plan (NBSAP).
Natural England Standing Advice
Natural England has adopted national standing advice for protected species. It provides a
consistent level of basic advice which can be applied to any planning application that could
affect protected species. It replaces some of the individual comments that Natural England
has provided in the past to local authorities.
Regional and Local Planning Policy
Hertfordshire Biodiversity Action Plan
The Hertfordshire BAP is an important source of information for key stakeholders and decision
makers including land managers, developers, planners and others. During 2005/2006, a
review of the original habitat and species action plans, focussing on the objectives, targets and
actions. Hertfordshire BAP provides Species Action Plans (SAPs) for water vole, dormouse,
Natterer’s bat Myotis nattereri, otter, tree sparrow, song thrush, great crested newt as well as
Habitat Action Plans for woodland, wetlands, neutral grassland, chalk grassland, urban,
farmland and heathland.

Local Structure Plans
County, District and Local Councils have Structure Plans and other policy documents that
include targets and policies which aim to maintain and enhance biodiversity. These are used
by Planning Authorities to inform planning decisions.
