5 0 EXECUTIVE SUMMARY 0.1 On behalf of Greater Cambridge Partnership, Cambridge Ecology Ltd was commissioned in October 2017, to carry out a winter bird survey on land associated with Cambourne to Cambridge Better Public Transport Scheme. The survey comprised the sections between Bourne Airfield and Grange Road, Cambridge. Subsequently the survey area was extended to include the northern part of Bourn Airfield between the entrance at Wellington Way and entrance at Broadway. 0.2 The survey recorded a total of 53 bird species. Of these 24 species were considered to be of particular conservation importance. These species comprised Red Kite, Kingfisher, Woodcock, Skylark, Starling, Fieldfare, Redwing, Song Thrush, Mistle Thrush, Dunnock, Bullfinch, Linnet, Lesser Redpoll, Yellowhammer and Reed Bunting; plus, Mute Swan, Teal, Mallard, Shoveler, Snipe, Black-headed Gull, Stock Dove, Kestrel and Meadow Pipit, which are Amber listed on the Birds of Conservation Concern. 0.3 Without mitigation, the presence of these species could constitute a constraint to the scheme and therefore are of material consideration during the planning decision process. 0.4 The diurnal survey of Bourn Airfield recorded a total of 21 bird species in the survey area, between eastern and western entrances along the northern perimeter. Of these 9 species were considered to be of particular conservation importance. These species comprised Skylark, Dunnock, and Reed Bunting; plus, Black-headed Gull, Common Gull, Lesser Black-backed Gull, Stock Dove, Kestrel and Meadow Pipit, which are Amber listed on the Birds of Conservation Concern. 0.5 Without mitigation, the presence of these species could constitute a constraint to the scheme and therefore are of material consideration during the planning decision process. 0.6 During the nocturnal surveys between Bourn Airfield and Grange Road, Cambridge and on Bourn Airfield itself, no target species, namely wintering plovers (Lapwing and Golden Plover) or owl species were seen or heard. The absence of these species indicates that currently they do not constitute a constraint to the scheme. 0.7 Observations of bird behaviour during the survey visits indicated that the birds were using the survey area for feeding and roosting, and was therefore an important area for the survival of the species assemblage present. 0.8 The distribution of wintering birds recorded during the survey visits was not evenly spread across the survey area, but was focused on seven particular areas that provided the wintering birds with suitably safe feeding and roosting habitat.

6 0.9 Based on the findings of this survey, mitigation measures would be considered necessary; the detail of these would depend on the actual route of the scheme The mitigation measures would be necessary to enable the scheme to proceed without causing a significant adverse effect on the local wintering bird population During the winter bird surveys observation of other ecological features were made. A peak count of 11 Brown Hare was made; with six being the largest number seen together. Observations of their behaviour indicated that they were using the survey area for feeding, sheltering and courting Without mitigation, the presence of Brown Hare could constitute a constraint to the scheme and therefore are of material consideration during the planning decision process.

7 1 INTRODUCTION 1.1 On behalf of Greater Cambridge Partnership, Cambridge Ecology Ltd was commissioned in October 2017, to carry out a winter bird survey on land associated with the Cambourne to Cambridge Better Public Transport Scheme. The survey comprised the sections between Bourne Airfield and Grange Road, Cambridge. Subsequently the survey area was extended to include the northern part of Bourn Airfield between the entrance at Wellington Way and entrance at Broadway. 1.2 This survey was required to investigate the potential for wintering birds (especially wintering waders, i.e. Lapwing and Golden Plover; and wintering thrushes, i.e. Redwing and Fieldfare), to be present along the proposed route of the scheme and which could therefore potentially be affected by the development and could cause a constraint to the proposed development. If present, wintering birds would need to be considered further in relation to maintaining compliance with wildlife legislation and planning policy. 1.3 For clarity in this report the development site (or 'site') refers to land within the survey area including the red line boundary of the Cambourne to Cambridge Better Public Transport Scheme, and the northern part of Bourn Airfield. Aims and objectives 1.4 The objectives of the 2018 winter bird survey were to provide information on the: current assemblage and abundance of wintering birds in the survey area; presence of wintering waders, i.e. Lapwing and Golden Plover; and wintering thrushes, i.e. Redwing and Fieldfare; conservation status of the wintering birds found in the survey area; distribution of wintering birds of conservation concern found in the survey area; use of the survey area by wintering birds. Survey area 1.5 The site was located between Grange Road, Cambridge at the eastern end and the Bourn Airfield entrance off the A1303 at the western end. To the north the site was bordered by the A428 dual carriageway and to the south mainly by arable land. The site also included three potential park and ride sites; one at Bourne Airfield, one adjacent to Scotland Farm and the other near the water tower adjacent to Madingley Mulch. 1.6 In March 2018, land across the northern part of Bourn Airfield between the entrances at Wellington Way and Broadway; along which the scheme may pass in order to reach Cambourne, was added to the survey area. Cambridge Ecology 19/04/ P0608-R-006a

8 1.7 The survey area included a buffer zone up to 250m beyond the red line boundary of the Cambourne to Cambridge Better Public Transport Scheme. This excluded areas where access was not possible and excluded areas beyond significant features such as major roads (e.g. A428), commercial, and residential developments. These features were considered to likely influence the movement and behaviour of wildlife and beyond which the scheme would be unlikely to have an adverse effect. 1.8 Figure 1.1 shows the extent of the survey area. 1.9 Within the survey area: the dominant habitat was arable land; other habitats included amenity and improved grassland, tall ruderal, dense and scattered scrub, ephemeral/short perennial; habitats of conservation value included, semi-improved grassland, broad-leaved lowland deciduous woodland (including plantation woodland), traditional orchards, hedgerows, wet and dry ditches other waterbodies (such as ponds and a lake) and Bin Brook.

9 2 METHODS 2.1 The English names, scientific names and taxonomic order of birds detailed in this report follows the British List (BOU, 2014). Registration Mapping 2.2 The survey methodology involved standard territory (registration) mapping techniques as detailed in Bibby et al. (2000). Registrations of birds, using standard British Trust for Ornithology (BTO) two letter species codes, were placed onto an appropriate field map (scale 1:5000). Specific codes were also used to record the birds behaviour e.g. feeding, roosting. 2.3 Two diurnal surveys were made each month, plus a single nocturnal survey was carried out each month to detect wintering plovers (namely Lapwing and Golden Plover) and owls. 2.4 The survey area was walked at a slow pace in appropriately fine weather in order to locate and identify all individual birds observed. All field boundaries and suitable habitats were walked. Diurnal visits were undertaken generally between 08: over a 2-day period. The whole survey area was covered during each visit, using suitable optical equipment (binoculars and telescope) to observe bird behaviour. Survey routes were mapped and routes were alternated on each visit, to ensure that all areas were covered at various times of day across the duration of the survey. 2.5 The nocturnal visits were undertaken generally between 1800 and 2300 over a single evening, the focus for these surveys were the arable fields, where wintering plovers and owls may feed and/or roost at night. To detect birds at night, the surveyor used a thermal camera (Flir Scout BTS Series Thermal Night Vision Camera) to scan the fields and listened for the characteristic calls to detect the presence of wintering plovers and search for owls. 2.6 Surveys were undertaken between November 2017 and March 2018, with six survey visits taking place. The survey dates were as follows: 11 th -12 th and 24 th -25 th October th -10 th, 14 th and 20 th -21 st November th - 8 th, 11 th and 18 th -19 th December th -16 th, 26 th and 29 th -30 th January th -7 th, 15 th, and 21 st -22 nd February th -9 th, 19 th, 20 th and 23 rd March th -13 th, 23 rd, and 26 th -27 th March 2018 (Bourn Airfield) 2.7 The weather conditions encountered during the surveys are detailed in Table 2.1 Cambridge Ecology 19/04/ P0608-R-006a

These devises displayed Ordnance Survey (OS) base maps and the location of the surveyor - using Global Positioning Systems (GPS) technology. This aided in the accurate recording of the birds location. Upon completion of the surveys the data were then downloaded and used to create master maps. P0608-R-006a 10 Cambridge Ecology 19/04/2018

11 2.9 The conservation status of the species recorded as wintering were compared against the following criteria: Annex 1 of the EU Birds Directive (Directive 79/409/EEC); Schedule 1 of the Wildlife and Countryside Act 1981, (as amended); Species of Principal Importance Natural Environment & Rural Communities Act (2006), (as amended); UK Biodiversity Action Plan (UK BAP) priority species (Anon, 2007); Cambridge Biodiversity Action Plan Priority Species ( Birds of Conservation Concern (BoCC) Red/Amber List (Hayhow et al., 2017) The master maps were used for those species that are covered by one or more of the above criteria, to create a species of conservation concern distribution map. Arable Land Usage 2.11 A record of the arable field usage was made, as it was recognised that this could influence the winter bird distribution and assemblage. Survey Constraints 2.12 The surveys were carried out in suitable weather conditions and at a time of day when birds would likely be most active and visible to surveyors. The results were considered to provide a valid indication of the abundance, assemblage and distribution of winter birds within the survey areas at the time of the survey visits It was recognised that there were two specific constraints associated with the survey data. These are as follows: The survey of Bourn Airfield was carried out in March only and would not represent a full winter survey; therefore, the data may not be representative of the actual abundance, assemblage and distribution of wintering birds at the airfield. The surveys were carried out over one winter ; therefore, natural annual variations, and variations due to arable field management would not be identified These limitations should be noted and considered when using these data for any assessment of effects by the scheme proposals on wintering birds.

12 3 RESULTS 3.1 The English and Latin names of all the species recorded during the survey detailed in this report can be found in Appendix A. 3.2 The arable field usage varied and comprised; cereal, oil seed rape, and pea/bean crops. There were also some ploughed fields and unploughed fallow fields. To the east of the M11 motorway there were three fields sown with a game cover mix. Figure 3.1 illustrates the arable field usage within the survey area. Wintering birds between Bourn Airfield and Grange Road, Cambridge 3.3 During the winter bird survey, a total of 53 bird species were recorded between October 2017 and March Of these 24 species are considered to be of particular conservation importance, based on the criteria set out in para Two species (Red Kite and Kingfisher) are listed as Annex 1 species under the EU Birds Directive. Four species (Red Kite, Kingfisher, Fieldfare and Redwing) are listed as Schedule 1 species under the Wildlife & Countryside Act 1981 (as amended). Nine species (Skylark, Starling, Song Thrush, Dunnock, Bullfinch, Linnet, Lesser Redpoll, Yellowhammer and Reed Bunting) are listed as Species of Principal Importance under the NERC Act 2006, these species are also UKBAP priority species. Eleven species are Birds of Conservation Concern (BoCC) red listed (these comprise the nine UKBAP priority species, plus Mistle Thrush and Woodcock). Thirteen species are BoCC amber listed, of which nine species (Mute Swan, Teal, Mallard, Shoveler, Snipe, Black-headed Gull, Stock Dove, Kestrel and Meadow Pipit) were not listed on any other form of citation. 3.5 All species recorded during the winter bird surveys, their usage of the survey area, together with their conservation status are detailed in Table 3.1.

23 5 KEY POINTS AND FINDINGS 5.1 Winter bird surveys were conducted between October 2017 and March 2018 and therefore throughout the period when wintering birds would likely be present. Twelve of the visits were made during the day, in addition five nocturnal visits were made. 5.2 It is considered that the survey results present an accurate reflection of the wintering bird assemblage and species population size present during the wintering season between Bourn Airfield and Grange Road, Cambridge. 5.3 The diurnal survey recorded a total of 53 bird species between Bourn Airfield and Grange Road, Cambridge. The survey recorded a total of 53 bird species. Of these 24 species were considered to be of particular conservation importance. These species comprised Red Kite, Kingfisher, Woodcock, Skylark, Starling, Fieldfare, Redwing, Song Thrush, Mistle Thrush, Dunnock, Bullfinch, Linnet, Lesser Redpoll, Yellowhammer and Reed Bunting; plus, Mute Swan, Teal, Mallard, Shoveler, Snipe, Blackheaded Gull, Stock Dove, Kestrel and Meadow Pipit, which are Amber listed on the Birds of Conservation Concern. 5.4 During March 2018 the survey area was extended to include the northern section of Bourn Airfield itself. Four diurnal visits and one nocturnal visit were made. 5.5 As the survey of Bourn Airfield was only carried out during March, the survey was considered to partially inform the status of, assemblage and species population size present in the Bourn Airfield survey area. 5.6 The diurnal survey of Bourn Airfield recorded a total of 21 bird species in the survey area, between eastern and western entrances along the northern perimeter. Of these 9 species were considered to be of particular conservation importance. These species comprised Skylark, Dunnock, and Reed Bunting; plus, Black-headed Gull, Common Gull, Lesser Black-backed Gull, Stock Dove, Kestrel and Meadow Pipit, which are Amber listed on the Birds of Conservation Concern. 5.7 Without mitigation, the presence of the species of conservation importance could constitute a constraint to the scheme and therefore are of material consideration during the planning decision process. 5.8 During the nocturnal surveys between Bourn Airfield and Grange Road, Cambridge and on Bourn Airfield itself, no target species, namely wintering plovers (Lapwing and Golden Plover) and owl species were seen or heard. 5.9 The absence of these species indicates that currently they do not constitute a constraint to the scheme. Cambridge Ecology 19/04/ P0608-R-006a

24 5.10 Observations of bird behaviour during the survey visits indicated that the birds were using the survey area for feeding and roosting, and was therefore an important area for the survival of the species assemblage present The distribution of wintering birds recorded during the survey visits was not evenly spread across the survey area, but was focused on seven particular areas that provided the wintering birds with suitably safe feeding and roosting habitats For instance, wintering thrushes (e.g. Fieldfare, Redwing and Song Thrush) were feeding on the berries provided by the network hedgerows, such as those to the east of the M11 motorway The other areas particularly important to the wintering bird assemblage included: the balancing ponds adjacent and north of the A1303; the woodland and grassland associated with the covered reservoir adjacent to Madingley Mulch; Madingley Wood SSSI; the arable land between Madingley Rise and Coton Village; the land around Coton Orchard and Coton Country Park; and the mosaic of fields, scrub, network of hedgerows and grassland adjacent to Bin Brook, including the various city and county wildlife sites During the winter bird surveys observation of other ecological features were made. Brown Hare were observed, located on arable land south of the A1303 between Madingley Rise and Coton village, in the grassland associated with the covered reservoir adjacent to Madingley Mulch, game cover crop on the arable land to the east of the M11 motorway and on Bourn Airfield Based on the findings of this survey, mitigation measures would be considered necessary; the detail of these would depend on the actual route of the scheme The mitigation measures would be necessary to enable the proposed development to proceed without causing a significant adverse effect on the local wintering bird population During the winter bird surveys observation of other ecological features were made. A peak count of 11 Brown Hare was made; with six being the largest number seen together. Observations of their behaviour indicated that they were using the survey area for feeding, sheltering and courting Without mitigation, the presence of Brown Hare could constitute a constraint to the scheme and therefore are of material consideration during the planning decision process.
