YORK HOUSE_MAY 2017 Ecological Appraisal and Bat Building Inspection 21 February 2017 Fred Samaha Quantem Consulting LLP 3rd Floor Quality House Quality Court Chancery Lane London WC2A 1HP Dear Fred, York House, Islington – Ecological Appraisal and Bat Building Inspection Thank you for commissioning EPR, on behalf of The Office Group (TOG) to carry out an Ecological Appraisal and Bat Building Inspection on York House, 207-221 Pentonville Road within the borough of Islington. I understand that the current proposals include the addition of two floors to the existing building, plus extensions to the basement, reception and to the rear of the building; hereby referred to as the “Proposed Works”. York House is situated at National Grid Reference TQ306830 in the South West of the Islington Borough on Pentonville Road; approximately 480m east from Kings Cross St Pancras Train Station and 200m west from the Joseph Grimaldi Park. The surrounding land-use is a complex of office, retail and residential blocks within a largely urban setting of Islington, North London. This letter provides a summary of the survey methods, results and recommendations following the Bat Building Inspection with consideration for the predicted likely Zone of Influence of the proposed refurbishment works. This letter covers the ecological issues related to the Proposed Works in respect of the potential to affect roosting bats and any other ecological receptors. Zone of Influence In order to identify the full extent of any potential ecological issues associated with the Proposed Works, I have considered the likely Zone of Influence (ZoI) of the proposals. Considering the Proposed Works, most biophysical changes are likely to extend only to the building itself and immediately adjacent land; this has been identified as the Zone of Influence of the scheme. The principal potential for a negative impact on bats comes from the removal of any existing roof features, cladding or lead flashing, should they support roosting bats. 1 Relevant Guidance Legislation and Policy Legislation and policy relevant to the ecological assessment of the Proposed Works is set out under Appendix 1 and summarised below. In undertaking this assessment, I have had regard to best practice guidance, including that detailed within the Bat Conservation Trust’s (BCT) Bat Surveys, Good Practice Guidelines (BCT 2016). In preparing my recommendations, due consideration has been given to biodiversity conservation legislation and national and international nature conservation priorities and planning policy, including: Legislation providing protection for sites and species, including the Conservation of Habitats and Species Regulations 2010 (as amended) (the ‘Habitats Regulations’) and the Wildlife and Countryside Act 1981 (as amended); Biodiversity conservation priorities under the Natural Environment and Rural Communities (NERC) Act 2006, and London Biodiversity Action Plan (BAP); and Nature conservation policy under the local planning system, namely that detailed within the London Local Plan (2015) and Mayor’s Plan for London; including Policy 7.19; “Biodiversity and access to nature” as well as the Islington Borough Local Planning Policy: DM 6.5 “Landscaping, trees and biodiversity” and DM19.2 on “Biodiversity and Urban Greening” taken from the Islington Core Strategy (the adopted Local Plan document; see Appendix 1 for more details). Methodology The methods deployed for the completion of the Ecological Appraisal and Bat Building Inspection are set out under Appendix 2 to this document and described in further detail, where necessary below. The ecological appraisal and bat inspection comprised of a desktop study, followed by a site visit to complete an inspection of the building and map the habitats in the surrounding area. I visited the Site with my colleague Joshua Sowden (a Natural England licensed bat ecologist, Class Licence: 2016-24351-CLS-CLS) on Friday 20th January 2017. Weather conditions were sunny, clear and cold (3 degrees Celsius) at the time of survey. Desktop Study As part of desk study research, I have examined aerial photographs, recent and historic Ordnance Survey maps and other freely available online information sources such as the Government’s Multi- Agency Geographic Information for the Countryside (MAGIC) website, the National Biodiversity Network (NBN) and Greenspace Information for Greater London (GIGL) to identify any potential ecological receptors. Statutory Sites A data search was conducted by GIGL to provide protected or notable habitats and species, and non-statutory designated sites for wildlife conservation within 2km of the site from the Site. There are two Local Nature Reserves located within a 2km radius of the Site; Camley Street Natural Park and Barnsbury Wood, approximately 600m away and 1km away respectively. There were no other European or national statutory designated sites identified within the search radius, so no detrimental impacts as a result of the Proposed Works are predicted on any conservation sites. 2 Non-Statutory Sites There was a total of 52 Sites of Importance for Nature Conservation (SINCs) within the search area. The nearest SINC was part of London’s Canals (designated for Metropolitan Importance), which support a wide range of aquatic flora, a diverse fish community and breeding waterfowl. London’s network of canals fulfils an important function in allowing nature into heavily built-up environments. The nearest canal was approximately 200m West from the Site boundary, but due to the nature and scale of the Proposed Works and the urbanised environment in between them, no impacts are anticipated. Protected and Notable species Due to the habitats present within the Zone of Influence of the proposals and their relative isolation within the urban area, the potential for protected or notable species to be present is limited, so I have confined my advice below to those species with the potential to be present and affected by the proposals. Bats Activity records of five bat species have been recorded within a 2km of the Site. The nearest activity record was for a Common Pipistrelle and a Noctule Bat, both located approximately 446m North West from the Site. Other bat species which were also recorded within the 2km radius of the Site boundary included the Daubenton’s Bat, Leisler’s Bat and a Soprano Pipistrelle, which were all located over 500m away to the north or northwest. No bat records were identified within the Site boundary or the ZOI. Birds There were also several protected and notable bird records returned from the desk study search which could use the building and rooftops to nest, including species such as the Starling, House Sparrow and Black Redstart. Starlings are listed as a London Biodiversity Action Plan (BAP) species as well as a species of local conservation concern. The nearest Starling record was located 479m to the North of the Site boundary. House Sparrow were recorded just 200m North-West from the Site and is protected under Section 41 (NERC Act), BAP Priority London as well as being a local species of conservation concern. The nearest Black Redstart record fell 785m North-West of the Site boundary which is also listed as a BAP London Priority Species and under Schedule 1 of the Wildlife and the Countryside Act (1981) as amended. Relevant records are discussed further in the below text, as appropriate. Ecological Appraisal I undertook the initial Ecological Appraisal and investigated and mapped habitats within the potential Zone of Influence of your proposals, and made a note of any potential for features of ecological value to occur, that could be affected. A map showing the broad distribution of habitats that are present is provided as Map 2 enclosed with this letter. Target Notes (TNs) associated with Map 2 are provided within Appendix 3. Habitat and Botany Other than York House itself and associated hardstanding, the only other notable habitat types were planted ornamental trees including Cherry, Silver Birch and London Plane tree planted along Pentonville Road (Photograph 7). Surrounding the trees, were also three small circular flower beds overgrown with ornamentals and some weeds such as Shepard’s Purse, Common Chickweed, Bindweed, Ragwort and Dandelion (Photograph 8); these habitats have been mapped on Map 2. 3 On the roof, there were a number of tall ruderal and ephemeral species recently colonised, including Clubmoss, Willowherb species, young Elder, Willow and Buddleia, as well as similar common ruderal species in the flowerbeds below including Ragwort, Woody Nightshade and Perennial Ryegrass, these have been shown on Map 3. These are typical species that rapidly colonise urban areas if left undisturbed. The vegetation in the flowerbeds and on the rooftop, is of no intrinsic botanical value, but can be replaced post refurbishment of the building, ideally with native species to provide biodiversity enhancements. Further recommendations for biodiversity enhancement have been made below. Nesting Birds & Recommended Actions Birds are protected while nesting under the provisions of the Wildlife and Countryside Act (1981, as amended; see Appendix 1). The potential for nesting birds to be impacted during the Proposed Works should therefore be considered. The species most likely to nest within these features include Gulls, Pigeons or smaller urban species such as the Pied Wagtail. The most common bird to occur nesting on this type of tower block building in the London is the Feral Pigeon, which still warrant protection
