1. EXECUTIVE SUMMARY

MKA Ecology Ltd was commissioned to undertake a suite of nocturnal bat survey at the former CEMEX

site in Barrington in 2014. A Bat Inspection Survey completed in 2013 identified a number of buildings

and trees at the Application Site which have the potential to support roosting bats, or showed evidence

of roosting bats.

The Application Site is situated on the northern perimeter of Barrington Village in Cambridgeshire. The

area comprises Previously Developed Land (PDL) with 22 buildings and infrastructure associated with

the former Barrington CEMEX Cement Works. Some naturalised areas are also present including

woodland, scrub, ephemeral habitats, grassland and standing water. A development of dwelling houses

and associated landscaping has been proposed for the Application Site.

In order to identify any potential impacts on bats, and specifically roosting bats a suite of nocturnal dusk

emergence and dawn re-entry surveys were completed at the Application Site following best-practice

guidelines between May and July 2014.

Four species of bat were confirmed at the site (Common Pipistrelle, Soprano Pipistrelle, Noctule and

Brown Long-eared Bat), furthermore Myotis sp. were recorded, which was presumed to be either

Daubenton’s Bat or Natterer’s Bat. This is considered to be a moderate diversity of species for

Cambridgeshire.

Areas of higher activity for Pipistrelle bats and Noctule were identified and a Common Pipistrelle

commuting route was recorded. Recommendations are made to provide enhanced areas of bat foraging

habitat within the design scheme to include dark areas and native planting to encourage invertebrate

prey sources. Dark corridors should be maintained across the site, including in an east to west direction,

to facilitate the movement of bats across the landscape.

Three bat roosts were identified during the nocturnal survey effort at the Application Site. A transitory

roost for a single Common Pipistrelle was recorded within the Electrical Shop and this was considered

to be of Local value. A feeding perch for Brown Long-eared Bat was recorded within the Packing

Building and this was considered to be of Local value. A Soprano Pipistrelle transitory mating roost was

identified within the Storage Building and this was also considered to be of Local value.

The Proposed Development will involve the demolition of all existing buildings within the Application

Site. Where impacts are predicted on bat roosts it is necessary to obtain a European Protected Species

derogation licence. An outline mitigation strategy is proposed to support a licence application. This

mitigation strategy should take into account the following aspects;

Timing of works to avoid sensitive periods;



Briefing of onsite contractors;

Pre-works inspections;

Exclusion;

Supervised demolition;

Compensatory roosting and habitat provisions;

Sensitive lighting; and

Monitoring.

It is recommended that a detailed mitigation strategy should be developed at the detailed planning

stages and, following planning approval, a European Protected Species licence should be sought from

Natural England.



2. INTRODUCTION

2.1 Aims and scope of survey and report

In May 2014 MKA Ecology Ltd was commissioned to undertake a nocturnal bat survey at the former

CEMEX site in Barrington, which is proposed for development. This survey was commissioned following

recommendations set out within a Bat Inspection Survey Report produced by MKA Ecology Ltd (2013).

This initial assessment identified a number of buildings and trees at the Application Site which have the

potential to support roosting bats. Evidence of roosting bats was recorded in one of these buildings.

The aims and scope of the bat surveys and this subsequent report were to;

Undertake dusk emergence / dawn re-entry surveys, as necessary, at the Application Site to

confirm the presence/likely absence of roosting bats;

Where roosting bats are present, identify the species using the roost, the population size, the

type of roost and any access points used;

Assess the need for a European Protected Species (EPS) Mitigation Licence; and

Outline a suitable mitigation or enhancement strategy for bats at the Application Site, as

required.

2.2 Site description

The former CEMEX site is located within the ward of Orwell and Barrington and falls within the

jurisdiction of South Cambridgeshire District Council, and is hereafter referred to as ‘the Application

Site. The city of Cambridge lies approximately 9.5km to the north north-east. It is centred at approximate

National Grid Reference (NGR) TL 39362 50611 (539362E, 250611N). The Application Site is directly

bound: to the north by the former chalk quarry; east by Haslingfield Road/ Chapel Hill ‘B’ road; west by

agricultural land; and south by woodland.

The Application Site covers an area of approximately 46.17ha with 9.88ha comprising Previously

Developed Land (PDL) with 22 buildings and infrastructure associated with the former Barrington

CEMEX Cement Works. Some naturalised areas are present within the Application Site including

scattered trees, grassland areas, arable farmland and open water. The former Barrington CEMEX

Cement Works is no longer in operation, however a relatively small builders yard (not operated by

CEMEX) is present within the southern area of the PDL.

Waterbody 1 (W1) is also known as the Southern Lagoon or Gault Pit. It covers an area of approximately

1ha and is a freshwater lake. An area of dense woodland lies to the south of the Application Site.



Barrington Light Railway track, which is not currently operational, diagonally dissects the Application

Site which originates from Foxton running north-west to the existing cement kiln dust (CKD) Cells 1 and

2 within the former quarry.

2.3 Proposed development

Application for outline planning permission for the demolition of all existing buildings and structures, and

redevelopment to provide up to 220 residential (Class C3) units, formal and informal open space

including allotments, details of vehicular site access arrangements, car parking for Barrington Primary

School, new pedestrian links to Barrington village and Foxton Station, and associated works - all other

matters (Layout, Scale, Appearance and Landscaping) are reserved for future approval.

2.4 Summary of previous survey effort

A desk study, undertaken as part of a Preliminary Ecological Appraisal, identified a number of bats

which have been recorded within 2km of the Application Site. The species recorded within the area are

as follows;

Common Pipistrelle Pipistrellus pipistrellus;

A Pipistrelle bat Pipistrellus sp.;

Daubenton’s Bat Myotis daubentonii;

Natterer’s Bat Myotis nattereri;

A Long-eared Bat Plecotus sp.;

Noctule Nyctalus noctula; and

Barbastelle Barbastella barbastellus.

Further to this an internationally designated site is situated close to the Application Site. Eversden and

Wimpole Woods are designated as a Special Area of Conservation (SAC) for their breeding population

of Barbastelle. The site is also designated as a Site of Special Scientific Interest (SSSI) at a national

level. Eversden and Wimpole Woods are situated approximately 4.5km to the west of the Application

Site.

The species described above all show flexibility in their roosting preferences and are known to roost

within both building and trees (Dietz et al., 2009).

The surrounding landscape could be described as being of moderate quality for foraging bats. Although

the landscape is dominated by naturalised habitats these primarily comprise large open arable fields

which are generally unsuitable for bats. However, some of the boundary features, such as hedgerows

or ditches are likely to provide suitable features for foraging and commuting. A number of pockets of



woodland are also situated within the landscape and these are likely to offer further opportunities for

foraging bats.

Roosting opportunities for bats within the landscape are likely to be numerous. The village of Barrington

contains a wide diversity of buildings which are likely to provide roosting opportunities, including a

church situated less than 100m to the south of the Application Site. During Great Crested Newt surveys

undertaken in 2014 a number of Daubenton’s Bats were observed over the village pond, situated 200m

south of the site, in the very early evening suggesting a roost for this species is located very close to

this area. Mature trees in the surrounding landscape, within gardens, woodlands and farmland are likely

to provide further opportunities for roosting bats.

Within the Application Site are a number of habitats suitable for foraging bats including woodland,

standing water and grassland areas. The woodland areas and standing water are not likely to be

impacted by the proposed development which is largely restricted to the PDL. The PDL is dominated

by building and hardstanding although there are some naturalised habitats such as ephemeral

vegetation and grassland which may be suitable for foraging bats.

The Bat Inspection Survey (MKA Ecology Ltd, 2013) identified a number of potential bat roosts within

buildings and trees at the Application Site. A total of 17 buildings and five individual trees, in addition to

one cluster of three trees, were identified as having potential to support roosting bats. The location of

these buildings and trees, are shown in Figures 1 and 2 at the end of this section. These buildings and

trees are described in respective Tables 1 and 2.

Table 1: Summary of buildings with potential to support bats following Daytime Bat Inspection

Building Important Features / Evidence

Palletiser Building Limited internal roosting opportunities. Holes present on an internal concrete

wall (possible hibernation area due to cooler temperatures behind the wall).

2.5 Legislation and policy relevant to British bat species

All British bats are listed on Schedule 2 of the Conservation of Habitats and Species Regulations 2010.

Species on this schedule are designated as “European protected species” and are therefore subject to

the provisions of Part 3, Section 41 (Protection of certain wild animals) which make it an offence to:

deliberately capture, injure or kill a bat

deliberately disturb a bat

damage or destroy a bat roost

possess, control, transport, sell, exchange, or offer for sale or exchange any live or dead bat,

part of a bat or anything derived from a bat or any part of a bat

Disturbance is defined in Section 41 paragraph 2 as an action which is likely to:

impair their ability to survive, to breed or reproduce, or to rear or nurture their young

impair their ability to hibernate or migrate

affect significantly the local distribution or abundance of the species to which they belong

In addition to the above legislation all British bats are listed on Schedule 5 of the Wildlife and

Countryside Act 1981 (as amended) and are therefore subject to part of the provisions of Section 9

(Protection of certain wild animals) which makes it an offence to:

intentionally or recklessly disturb a bat while it is occupying a roost

intentionally or recklessly obstructs access to a bat roost

sell, offer, expose for sale, possess or transport for the purpose of sale, any live or dead bat or

any part of, or anything derived from a bat

publish or cause to be published any advertisement likely to be understood as conveying that

an individual buys or sells, or an intention to buy or sell bats

Some bat species are identified as “species of principal importance” in relation to Section 41 of the

Natural Environment and Rural Communities Act 2006 and as such are listed as UK Biodiversity Action

Plan (BAP) Priority Species. These species include:

Barbastelle

Bechstein’s Bat Myotis bechsteinii



Noctule

Soprano Pipistrelle

Brown Long-eared Bat Plecotus auritius

Greater Horseshoe Bat Rhinolophus ferrumequinum

Lesser Horseshoe Bat Rhinolophus hipposideros

Pipistrelle bats are included within the Cambridgeshire BAP.

3. METHODOLOGY

3.1 Dusk emergence and dawn re-entry bat roost surveys

The dusk emergence and dawn re-entry surveys followed the best-practice guidance described by the

Bat Conservation Trust (2012).

Surveyors were positioned around the structures to ensure all key aspects of the building/tree could be

observed. Any bats emerging / entering were recorded and the time and species noted. All bat activity

observed on site was recorded and flight-lines were mapped. The start and finish time of the

emergence/re-entry survey was recorded, as was the date, wind direction and force, temperature,

precipitation and cloud cover for each survey. A map of the habitat to be surveyed was drawn in order

to show any bat emergence/re-entry locations.

Emergence surveys began 15 minutes before sunset and continued for approximately 1.5 to two hours

after sunset. Re-entry surveys began approximately two hours before dawn and finished at dawn.

Surveyors used broadband bat detectors (BatBox Duet) as well as Pettersson D240x time expansion

detectors for further supporting data. Edirol digital recorders were used to collect bat call data which

was later analysed using BatSound software. Identification of bat calls was undertaken using the

parameters set out by Russ (2012).

The level of survey effort at each feature was determined by the likelihood of the presence of bat roosts.

Low potential features were surveyed on one occasion, moderate potential features were surveyed on

two occasions and high potential features were surveyed on three occasions. As a roost was identified

at the Packing Building during the Bat Inspection Survey a total of three surveys were carried out at this

structure. Where features were located in close proximity they were surveyed together. Table 3

describes the level of survey effort at each feature.

3.2 Surveyors

The surveys were undertaken by Will O’Connor (Natural England Bat Licence Number CLS000599)

(nine years’ bat working experience), Steve Coyne (Natural England Bat Licence Number CLS02791)

(six years’ bat working experience), Marcus Kohler (nine years’ bat working experience), James

Aldridge (one years’ bat working experience), Oliver Richings (three years’ bat working experience),

Sofia Morcelle (two years’ bat working experience) and Tamsyn Bridger (two years’ bat working

experience) of MKA Ecology Ltd. They were assisted by Ann Sherwood, Rowan Rumball, James

Hanlon and Ken Coyne.

Bat call analysis was undertaken by Will O’Connor, Steven Coyne, Tamsyn Bridger and Sofia Morcelle.

3.3 Constraints on the methodology

The results taken from detector recordings are biased towards bats that use louder echolocation calls.

Therefore quiet bats, such as Brown Long-eared Bat, may be under-recorded due to the limited

recording range of the equipment. This was not considered to present a significant constraint as

surveyors were vigilant to ensure that visual cues indicating the presence of quiet species were

recorded.

In some circumstances it is not possible to confirm the species of bat with absolute confidence using

sound analysis techniques. In particular some calls of Common Pipistrelle and Soprano Pipistrelle

overlap making species identification difficult. In these circumstances the bat can be identified as a

Pipistrellus sp. only. Within this report where Pipistrellus sp. is used this refers only to Common

Pipistrelle and Soprano Pipistrelle. This should not be interpreted as other species of the Pipistrellus

genus, such as Nathusius’ Pipistrelle Pipistrellus nathusii which, although it occurs relatively frequently

within the UK is not commonly recorded. Where Pipistrelle species other than Common or Soprano are

suspected this will be directly referenced and discussed within the report. Similarly calls of Myotis



species can demonstrate a large number of overlapping parameters making identification difficult.

Where this is the case the bat call has been labelled as Myotis sp.

No other significant constraints were encountered during the survey effort.



4. RESULTS

The following species of bat were recorded during the survey effort at the Application Site;

Pipistrellus sp.;

Common Pipistrelle;

Soprano Pipistrelle;

Noctule;

Brown Long-eared Bat; and

Myotis sp. (Natterer’s or Daubenton’s)

Raw survey data for each building/tree are provided within Appendix 1.

The first bat recorded was a Pipistrellus sp. to the west of the building at 21:27. This bat was recorded

over 30 minutes after dusk which suggests that it is not roosting close to this location. Following this

sporadic activity for Common Pipistrelle, Soprano Pipistrelle and Noctule was recorded.

No bats were recorded roosting within the Palletiser Building.

The first bat recorded was a Common Pipistrelle. This bat was observed emerging from below the

bargeboard on the northern aspect of the building at 21:31. Following this sporadic foraging activity was

recorded for Common Pipistrelle, Soprano Pipistrelle and Pipistrellus sp. with two Common Pipistrelle

bats recorded on occasions.

16 July 2014 – dusk emergence survey

The first bat recorded was a Soprano Pipistrelle at 22:10 which was almost one hour following dusk

which suggests that bat is not roosting close to this location. A lower level of bat activity was recorded

during this survey with occasional Common Pipistrelle and Pipistrellus sp. recorded.

A Common Pipistrelle bat roost was recorded at the Electrical Shop (one bat).

A number of Noctule bat passes were recorded around the building at 21:39, an hour after dusk which

suggests that this early emerging species is not roosting close to this location. It is considered likely

that the Noctule bat was foraging around the lamps to the north of the Packing Building which is

relatively common behaviour for this species. Following this a low level of bat activity was recorded with

several Common Pipistrelle passes.


The first bat recorded was a Common Pipistrelle foraging to the south of the building at 21:40. This was

almost an hour after sunset which suggests that the individual is not roosting close to the building. A

number of Noctule passes were recorded around the building and these were believed to be individuals

foraging around the floodlights. Two Brown Long-eared Bat passes were recorded to the south of the

building although these individuals were not observed.

10 July 2014 – dawn re-entry survey

No bats were recorded during this survey.

Although no bats were recorded roosting in this building during the nocturnal surveys the

daytime inspection revealed the presence of a Brown Long-eared Bat feeding roost in the

Packing Building.

The first bat recorded was a Soprano Pipistrelle at 21:07 which was only 20 minutes following sunset

which suggests that this bat may be roosting close to this location. Following this intensive Pipistrelle

bat activity was recorded within the trees to the south and east of the building.

10 July 2014 – dawn re-entry survey

Frequent Pipistrelle bat activity was recorded around the building within the surrounding trees. Foraging

and social calling activity was recorded. Several Noctule passes were recorded during the survey but

these bats were not observed and were considered to be flying high over the survey location. The last

bat, a Common Pipistrelle, was recorded at 04:14 which was over 30 minutes before dawn.

No bats were recorded roosting within the Canteen.

recorded at this location.


The first bat recorded was a Soprano Pipistrelle towards the north of Office 1 at 21:46. This was

approximately 30 minutes after sunset which suggests that the bat is roosting relatively close to this

location. Following this sporadic Pipistrelle bat activity was recorded around the building with a small

number of Noctule also recorded.




The first bat recorded was a Common Pipistrelle at 21:44 which was approximately 30 minutes after

sunset which suggests that the bat is roosting relatively close to this location. Following this a moderate

level of Pipistrelle bat activity was recorded around the building with occasional Noctule passes. At

22:20 a Brown Long-eared Bat was recorded to the south of Office 1 but the direction of flight was not

observed.

No bats were recorded roosting within Office 1.

Common Pipistrelle was recorded at this location.


The first bat recorded was at 21:40, less than 30 minutes after dusk, which suggests that this bat is

roosting close to this location. The bat was observed flying north past the building. Following this a

further Common Pipistrelle was observed flying in the same direction which suggests a commuting

route for this species. A low level of Common Pipistrelle activity was recorded at this location with some

foraging to the south of the building and on the track to the east.

No bats were recorded roosting at Substation 3.

Common Pipistrelle, Soprano Pipistrelle, Pipistrellus sp., Noctule, Brown Long-eared Bat, Myotis sp.

(presumed Daubenton’s Bat) were recorded at this location.


The first bat recorded was a Common Pipistrelle flying north at 21:12, only 20 minutes after dusk which

suggests that this bat is roosting close to this location. The movement of Common Pipistrelle is this

direction shortly after dusk is consistent which the commuting route described in Section 4.6. Following

this, high levels of Pipistrelle bat activity was recorded with foraging bats observed along the treelines

to the south and west around the buildings. A low number of Noctule passes were recorded with one

individual flying directly south at 22:06.


The first bat recorded was a Common Pipistrelle at 21:39 which was observed foraging along the

treeline to the south of the Chimney. Following this moderate levels of Pipistrelle activity were recorded

eared Bat pass was recorded at 22:13 close to the Water Tank Building. A single Noctule pass was

recorded at 22:42 and a single Moyotis sp. (presumed Daubenton’s Bat) bat pass was recorded at

22:43 in the same location.

No bats were recorded roosting at Back-end Kiln, Chimney and Water Tank Building.

The first bat recorded was a Common Pipistrelle to the east of the building at 22:04. Following this, four

Soprano Pipistrelle emerged from a roost below a gutter on the eastern aspect of the building between

22:13 and 22:23. The first emergence was nearly one hour after sunset which is particularly late for this

species which typically emerges 20 – 30 minutes after sunset (Russ, 2012) or 30 minutes after sunset

(BCT, 2012). However, the cloud cover was minimal on this evening which may have resulted in higher

light levels. Furthermore the full moon occurred on 12 July 2014 which is likely to have further increased

light levels and therefore delay emergence.


Low levels of bat activity were recorded during this survey with only two Noctule passes recorded and

a single Pipistrellus sp. pass.

9 September 2014 – dusk emergence survey

Soprano Pipistrelle bats were present in the survey area within five minutes of the survey starting,

however, no emergences from the target trees were recorded. Pipistrelle activity continued with



constant foraging and frequent social calls until 19:44 where activity began to rapidly decrease with only

two more passes in the remainder of the survey.

Four additional species were recorded with Common Pipistrelle passing occasionally between 19:47

and 20:48, Brown Long-eared was recorded on three occasions between 19:45 and 20:08, Noctule was

recorded on one occasion at 20:39 and an un-identified Myotis species (likely to be either Natterer’s or

Daubenton’s) was recorded at 20:57.

Most bats were not directly observed and therefore flight lines were not mapped. These bats were

assumed to be concentrating their activity on the moat behind the observer positions.


Bat activity was first recorded in the survey area at sunset (19:25) with Soprano Pipistrelle bats foraging

and producing social calls. A high intensity of activity continued for 30 minutes and then only a single

pass was recorded after this point.

Common Pipistrelle activity was first recorded at 19:50 and continued with occasional passes until

20:19. Active foraging and social calling was recorded.

Two additional species were recorded during this survey with Brown Long-Eared passing once at 20:01

and an un-identified Myotis species (likely to be either Natterer’s or Daubenton’s) was recorded four

times between 20:09 and 20:16.

No bats were recorded roosting at Tree 6 and Tree 7.

4.19 Summary of bat activity


Brown Long-eared Bat), furthermore Myotis sp. were recorded, one of which was presumed to be a

Daubenton’s Bat although this could not be confirmed with sound analysis due to the high degree of

overlap in call parameters that this species group shows.

Activity for the Pipistrelle bats was of a moderate level with focussed area of activity within the trees

around Office 2 and the Canteen. Further areas of higher activity for these species were recorded on

the southern boundary, along the treelines, at the south of the PDL, close to the Chimney, Water Tank

Building and in the woodland near the moat near the south east boundary. Noctule activity was

widespread but at low levels with some preference shown for the north of the PDL where foraging

activity was presumed to be taking place around the floodlights in this area.

A single commuting route was identified for Common Pipistrelle at the site which appeared to be used

on a number of occasions. At dusk Common Pipistrelle is thought to commute from the woodland to the

south of the PDL, past the eastern side of the Chimney via Substation 3 and the Kiln Building to the

area around Office 2 and the Canteen where higher levels of activity for this species were recorded. It

is considered likely that there is a roost for this species to the south (potentially within Barrington Hall

or the church) and the species follows this route to initially forage within the trees around Office 2 and

the Canteen to then disperse into foraging areas within the wider landscape.

The known roosts, areas of higher activity and commuting routes are shown on Figure 3 below.

*Myotis sp. recorded at the Application Site were considered highly unlikely to be rare species such as

Bechstein’s or Althacoe bats.

Common Pipistrelle

Common Pipistrelle is a common and widespread species throughout England (Wray et al., 2010). The

species is flexible in relation to its habitat requirements and can be found in both urban and rural

landscapes. Common Pipistrelle bats will usually forage along linear features such as hedgerows or

tree lines (Dietz et al., 2009) although the species is known to forage and fly over more open habitats

(personal observations).

Areas of higher activity for Pipistrelle bats were recorded around Office 2 and the Canteen as well as

alongside the treelines to the south of the PDL. The species was frequently encountered.

A commuting route for Common Pipistrelle was recorded at the site (see Figure 3). It is considered likely

that a Common Pipistrelle roost is present to the south of the PDL with possible locations in Barrington

church or Barrington Hall. Bats were observed moving north through the PDL where they appeared to

congregate within the trees around Office 2 and the Canteen before dispersing into the wider

countryside to forage. It can be typical of Pipistrelle bats to forage and gather in sheltered areas close

to roosts prior to dispersing across the landscape when light levels fall and the risk of predation is

lowered.

Soprano Pipistrelle

Soprano Pipistrelle is also a common and widespread species throughout England. As with the

Common Pipistrelle it has flexible habitat requirements although there is some evidence to suggest the

species has a preference for riparian (aquatic edge) habitats (Dietz et al., 2009).

Areas of higher activity for Pipistrelle bats were recorded around Office 2 and the Canteen as well as

alongside the treelines to the south of the PDL. The species was frequently encountered.



Brown Long-eared Bat

Brown Long-eared Bat is considered to be a common and widespread species within England (Wray et

al., 2010). Brown Long-eared Bat is considered to be a woodland or woodland edge species foraging

close to vegetation (Dietz et al., 2009).

The species was infrequently encountered at the Application Site with occasional passes recorded

across the area. It should be noted that this species is difficult to identify due to the typically quite

echolocation calls resulting in a low detection rate during bat detector surveys.

Noctule

Noctule is considered to be a rarer species in England (Wray et al., 2010) although its distribution is

widespread. The species roosts almost exclusively in trees within the UK although a number of roosts

have been recorded in buildings. Noctule is one of the larger species within the UK and is a strong flyer.

The species forages high above vegetation and usually out in the open with rapid dives for prey.

Furthermore the species has been known to forage around congregations of invertebrate prey at street

lights (Dietz et al., 2009).

An area of higher activity for Noctule was observed to the north of the Packing Building where the

species was suspected to be foraging around the floodlights which are situated in this area. The species

was also recorded across the survey area.

Myotis sp.

Myotid bats are considered to be rarer species within England, albeit their distribution is relatively

widespread, although distribution of some species within the genus can be localised. It was considered

highly unlikely that the Myotis sp. registrations recorded during the survey effort were rarer species of

this group such as Bechstein’s or Althacoe bats.

Myotid bats are typically species of woodlands and woodland edge/hedgerow habitats (BCT, 2012)

although some species specialise in particular habitats (for example Daubenton’s Bat which primarily

forages over still water).

Distinguishing Myotis sp. with sound analysis can be difficult as the species’ calls display a large degree

of overlap, particularly when bats are flying within a cluttered environment. However, some of the call

parameters of the Myotis sp. recorded at Barrington resembled those of Daubenton’s Bat, although this

could not be confirmed with absolute certainty. A suspected Daubenton’s Bat roost was identified close

to the village pond, situated 200m south of the site, during Great Crested Newt surveys in Spring 2014.



There is some scope for this species to commute across the Application Site to forage over the lakes

within the quarry. Overall Myotis sp. were encountered infrequently during the survey effort.

5.2 Bat roosts

A number of roosts were identified during the nocturnal emergence and re-entry roost surveys

undertaken at the Application Site in 2014. These roosts are described and evaluated below. The

evaluation of roosts is undertaken within a geographic context and adapted from Wray et al. (2010) and

these categories are shown in Table 23 below.

Common Pipistrelle single bat transitory roosts – Local value

A single bat was observed emerging from below a bargeboard on the northern aspect of this building

on 19 May 2014.

Packing Building

Brown Long-eared Bat feeding perch – Local value

The Bat Inspection Survey (MKA Ecology Ltd, 2013) identified this feeding perch for Brown Long-eared

Bat although no activity was observed at this location during the nocturnal survey effort. As the

droppings identified within 2013 were fresh it is considered that this remains an active roost although it

may be infrequently used.

Storage Building

Soprano Pipistrelle – transitory mating roost (low numbers) – Local value

Four Soprano Pipistrelle bats were observed emerging from below a gutter on the eastern aspect of

this building on 15 July 2014.

Maternity roosts for Soprano Pipistrelle comprise a minimum of 15 – 20 females (Dietz et al., 2009) and

therefore the roost at the Storage Building is considered unlikely to be a maternity roost. The emergence

event was recorded in mid-July which is the peak maternity season and if a maternity roost was present

higher numbers would be expected at this time.

Mating roosts for Soprano Pipistrelle are occupied from June and from July they will display from these

locations to attract small numbers of females (Dietz et al., 2009). It is considered likely that the time of

this roost was observed, and the numbers of bats present, indicate the presence of a mating roost.

However, this roost is transitory in nature as it was not present during a repeat survey on 17 July 2014.



6. MITIGATION AND RECOMMENDATIONS

6.1 General bat activity

As it is evident that bats are utilising the site it is recommended that habitat enhancement measures

are put in place to ensure that foraging areas are available. Areas of scrub, grassland and woodland

should be incorporated into the design scheme to provide areas for foraging bats. Native planting should

be used to ensure that habitat is available to support bat prey such a flying invertebrate species.

Recommendation 1: In order to enhance the biodiversity within the Application Site, it is recommended

that areas of green space are included within the design scheme. These areas should contain native

planting to encourage and promote the availability of prey sources for bat species.

In order to provide enhanced opportunities for roosting bats it is recommended that bat boxes are

included within the design scheme. A variety of box designs should be considered throughout the

Application Site to include integrated boxes within built structures, boxes mounted on external surfaces

of built structures and boxes mounted on trees at the site. A part of wider Biodiversity Management

Plan for the Application Site a bat box scheme should be developed and agreed with the Local Planning

Authority. The box scheme should take into account any necessary mitigation required as part of the

European Protected Species licensing process described below.

Recommendation 2: In order to enhance the biodiversity within the development site, it is

recommended that a bat box scheme is developed as part of a wider Biodiversity Management Plan for

the Application Site. This bat box scheme should be agreed with the LPA.

Bat roosting behaviour, commuting and foraging activity can be dramatically affected by artificial

lighting. It is recommended that a sensitive lighting scheme is developed for the Application Site to

ensure that there is no unnecessary light spill. Security lighting should be fitted with a short timer, and

down-lighting should continue to be used where required. Hoods or cowls can be used to prevent light

spill into tree canopies.

New roosting provisions, as described above, should not be directly lit and dark corridors should be

maintained across the site. In particular the Common Pipistrelle commuting route along the eastern side

of the PDL should remain unlit where feasible. Furthermore, dark corridors should be developed in an

east to west direction across the Application Site to facilitate the movement of bats.

Recommendation 3: A sensitive lighting strategy should be developed for the Application Site to take

into account key foraging areas and commuting routes. Roosting provisions should not be directly lit

and dark corridors should be established from east to west across the Application Site.



6.2 Bat roosts

Licensing requirements and the ‘three tests’

Where impacts on a bat roost are predicted it is necessary to obtain a European Protected Species

derogation licence. A licence is required for disturbance, modification or destruction of a bat roost.

Licensing should be considered as a last resort and working methods which avoid the need for a licence

should be explored first. In some circumstances it is not possible to avoid the need for a licence and

this is likely to be the case for the roost at the Application Site.

In order to obtain a licence the applicant must satisfy three tests to show that;

The conservation status of the species can be maintained;

That there is a proven need for the proposed works; and

That there is no satisfactory alternative.

The licence application forms two parts; the method statement and the reasoned statement. The

method statement is produced by the ecologist and should be designed to meet the conservation status

test. The method statement will outline the current status of bat species at the site and describe in detail

how this will be maintained through mitigation and compensation. The method statement will form part

of the final licence agreement which will be a legally binding document. It is therefore of the utmost

importance to ensure that all parties are satisfied with the proposals within this document as changes

can be time consuming and cause delays.

The reasoned statement addresses the final two tests and is usually prepared by the developer of the

site. The purpose for the works will fall into one of two categories 1) Preserving Public Health or Public

Safety or 2) Imperative Reasons of Overriding Public Interest. The proposals at Elizabeth House are

likely to fall in to the latter category. It will be necessary to demonstrate that there is a significant socio-

economic need for the proposed works which is likely to concentrate on the requirement for further

student accommodation for the college and the requirement for building renovation. Evidence of this

need will be required to support the reasoned statement.

The reasoned statement will also need to satisfy the no satisfactory alternative test. It will be necessary

to show that other alternatives have been considered within the design scheme and provide reasons

as to why these were considered inadequate. In addition it will be necessary to consider the ‘do nothing’

option and explain why this is not satisfactory.



Mitigation Strategy

The following outline mitigation strategy is proposed for the Application Site. As no final master plan

has been developed it is not feasible to provide a detailed mitigation strategy at this stage, although the

principals of the mitigation are defined below. It should be noted that this may be subject to further

changes during liaison within Natural England within the licence application process.

The overall aim of the mitigation should be to ensure that there is no detriment to the conservation

status of bats. This entails the maintenance of the population likely to be affected by the development

and wherever possible the addition of enhancing features of benefit to this population.

Mitigation should be proportionate and Table 24, shown at the end of this section, provides guidelines

for proportionate mitigation as described by Mitchell-Jones (2001) in the Bat Workers’ Manual. At the

Application Site three roots are present, all of which are considered to be of local value. In these

circumstances it is recommended that timing constraints are placed on the work to avoid hibernation

season, that like-for-like roost replacements are provided prior to works, and that monitoring is

undertaken for two years subsequent to the works.

Stage 1 – Mitigation to prevent harm to individual bats

Timing of works. Works to the building should be avoided during the hibernation period when disturbed

bats will not have sufficient energy reserves or food sources to survive. The hibernation period for bats

runs from November to February inclusive, and so works should be scheduled for outside of this time

period.

Briefing of onsite contractors. All onsite contractors will be made aware of the presence of bat roosts

and the legislation that protects these species. All onsite contractors will be made aware of the contents

of the method statement (as this will be legally binding and must be adhered to). A briefing will be

provided by a licensed bat ecologist to detail the contents of the method statement and outline the

process which should be followed. A hard copy of the method statement will be present on site at all

times for reference.

Pre-works inspection. Prior to any works on site a bat inspection survey will be undertaken to identify

the locations of any roosting bats.

Exclusion. During the pre-works inspection survey any roosting locations which are suitable for bats

but not occupied by bats will be blocked to ensure that they are not used during works. Where bats are

identified during the pre-works inspection, or where areas cannot be adequately inspected (such as

deep crevices), one way non-return valves will be fitted for five nights (of fair weather conditions) to

allow bats to leave and not return.



The non-return valves will be made using plastic down pipe (approx 60mm diameter), in lengths of

around 200mm, with a 100mm length plastic sleeve of similar diameter (see Figure 4). The downpipe

will be cut to fit the hole or gap, and placed no more than 50mm into the gap. Different gauges of pipe

will be available should they be required. Where the pipe does not cover the entire gap, foam sponge

material will be stuffed in the gaps then sealed with tape.

Figure 4: Illustrative diagram of non-return value (note that caulk will be replaced with foam

sponge material)

Supervised soft demolition. Following the exclusion of bats from all suitable roosting locations a

licensed bat ecologist will supervise the removal of any key areas which may contain roosting bats. This

will include removal of roof tiles if applicable.

If a bat is discovered during unsupervised times work will cease immediately and the licensee will be

called for advice. This advice will include leaving the bat to disperse of its own accord, or to wait until

the licensed bat handler has arrived to move the bat if required. Building contractors will be explicitly

forbidden from handling bats.

Any bats found during works will be moved to a secure location should this be required. Bats will be

moved to the bat boxes to be positioned at the site. In the event of a bat being discovered during works

the following order of process will be observed:

1) If the bat is found during un-supervised periods the licensee will be immediately called for assistance.

2) The bat will allowed time to move of its own accord.



3) Should the bat show no signs of movement the bat will be moved to bat boxes positioned around the

site.

Only the licensed bat ecologist will handle any bats. The licensed ecologist will wear Showa bat handling

gloves during this process. Bats will be placed in a bat handling bag when being moved across the site.

Stage 2 – Compensation to provide adequate alternative roosting provisions

It is recommended that a bat box scheme is installed at the Application Site to allow for roosting

provisions for Common Pipistrelle, Soprano Pipistrelle and Brown Long-eared Bat. The exact nature of

the bat box scheme should be developed at a later detailed planning stage. However, a number of

boxes must be mounted in the mature trees surrounding the Application Site prior to works. These

boxes will serve two purposes. The primary purpose will be to provide roosting provisions for bats during

the works at the site. The secondary purpose will be to provide a safe location to which any bats found

during the work can be placed.

Surrounding habitat provisions. Existing vegetation around the site should be enhanced with native

planting.

Lighting strategy. A sensitive lighting scheme should be developed to ensure that there is no

unnecessary light spill within the site. Down-lighting should be used and any security lighting will be

fitted with a short timer. No roosting provisions or access points should be directly lit and dark corridors

should be maintained across the site. In particular the western part of the site in which the majority of

bat activity was recorded should not be lit.

Stage 3 – Monitoring

Bat boxes and compensatory roosting provisions should be monitored annually for two years

subsequent to completion of the construction works.

It is only possible to obtain a European Protected Species Licence once all planning permission has

been granted.

Recommendation 4: Obtain planning permission for the Proposed Development prior to an EPS

mitigation licence application.

Recommendation 5: Obtain a European Protected Species mitigation licence for the Proposed

Development at the Application Site. This licence will comprise two sections which are the Reasoned

Statement and Method Statement. The Reasoned Statement will outline the need for the proposed

development and why there is no satisfactory alternative. The Method Statement will outline how the

conservation status of the bat species will be maintained through mitigation and compensation.

In order to satisfy Natural England, the government body issuing European Protected Species licences,

that the conservation status of the species can be maintained at the site, it will be necessary to develop

a mitigation strategy to achieve this. A proposed outline mitigation strategy is set out above but this may

be subject to some change during liaison with Natural England in the licence application stage.

Recommendation 6: Undertake all work in accordance with the bat mitigation strategy agreed with

Natural England.

6.3 Survey data lifespan

In order to inform a European Protected Species licence application bat survey data should be updated

in the survey season (May to August) immediately preceding the application. A full suite of surveys is

unlikely to be required although, as a minimum following a one year delay, it would be necessary to

ensure no significant changes have occurred at the site before submitting an application. For delays of

over one year but less than two it would be necessary to repeat nocturnal survey effort at roost site to

inform a licence application. For delays of over two years it is recommended that daytime and nocturnal

survey effort is repeated across the site.

Recommendation 7: Ensure that bat survey data is up to date prior to making a European Protected

Species licence application.



7. CONCLUSIONS

MKA Ecology Ltd was commissioned to undertake a suite of nocturnal bat survey at the former CEMEX

site in Barrington in 2014. A Bat Inspection Survey completed in 2013 identified a number of buildings

and trees at the Application Site which have the potential to support roosting bats, or showed evidence

of roosting bats.

Nocturnal dusk emergence and dawn re-entry surveys were completed at the Application Site following

best-practice guidelines between May and July 2014.


Brown Long-eared Bat), furthermore Myotis sp. were recorded, one of which was presumed to be either


Cambridgeshire.

Areas of higher activity for Pipistrelle bats and Noctule were identified and a Common Pipistrelle

commuting route was recorded. Recommendations are made to provide enhanced areas of bat foraging

habitat within the design scheme to include dark areas and native planting to encourage invertebrate

prey sources. Dark corridors should be maintained across the Application Site, including in an east to

west direction, to facilitate the movement of bats across the landscape.

Three bat roosts were identified during the nocturnal survey effort at the Application Site. A transitory

roost for a single Common Pipistrelle was recorded within the Electrical Shop and this was considered

to be of Local value. A feeding perch for Brown Long-eared Bat was recorded within the Packing

Building and this was considered to be of Local value. A Soprano Pipistrelle transitory mating roost was

identified within the Storage Building and this was also considered to be of Local value.

The master plan for the Proposed Development has not been established at this stage although it is

considered highly likely that the existing buildings within the PDL will be demolished. Where impacts

are predicted on bat roosts it is necessary to obtain a European Protected Species derogation licence.

An outline mitigation strategy is proposed to support a licence application. This mitigation strategy

should take into account the following aspects;

Timing of works to avoid sensitive periods;

Briefing of onsite contractors;

Pre-works inspections;

Exclusion;

Supervised demolition;

Compensatory roosting and habitat provisions;

Sensitive lighting; and



Monitoring.

It is recommended that a detailed mitigation strategy should be developed at the detailed planning

stages and following planning approval a European Protected Species licence should be sought from

Natural England.
