Its contents must not be copied or reproduced in whole or in part for any purpose without the written consent of Lockhart Garratt Ltd. DISCLAIMER It should be noted that the information above provides details of the Site’s current ecological situation. In the event that the proposed development does not commence within 12 months of the date of this report, further advice should be sought from a suitably qualified ecologist as to whether the information provided requires updating in light of changing ecological conditions. 18-2765 EXTENDED PHASE 1 SURVEY REPORT V1 SA 010319 Page 3 of 52 Executive Summary Purpose of Document Lockhart Garratt Ltd was commissioned by Marlborough College to carry out an Extended Phase 1 Habitat Survey including desk study for the Kennet Building and surrounding habitats subject to re- development. The Site itself is not subject to any statutory or non-statutory designation. There was one statutory designation and 11 non-statutory designations within 2km of the Site. A range of protected mammal and bird species were identified within 2km of the Site by the desk study. The Extended Phase 1 Survey was undertaken on 19th February 2019. The habitat within the Site consisted of built environment, amenity grassland and ornamental shrubs and planting. The report considers the ecological conditions within the Site in the context of a potential future planning application for the redevelopment of the Site to provide new school facilities for the wider Marlborough College complex. Overall it is considered that subject to the implementation of the recommendations and enhancements set out within this report, an overall net gain in biodiversity at the Site may be achieved. Recommendations, in this context, are as follows: Further survey work in respect of bats is recommended due to the presence of suitable features to support crevice dwelling bats. The Kennet Building has been categorised as having Low Suitability. Further survey work in respect of water vole and otter is recommended due to the proximity of the wet ditch system and anticipated impacts upon this habitat as a result of the proposed works. Further survey work in respect of crayfish is recommended as several d-shaped burrows were identified along the wet ditch to the south of the site. Clearance and construction works should be scheduled outside of the main bird breeding season (March to August inclusive). If in the event works need to proceed within this period, then specialist advice from a suitably qualified ecologist should be sought. Any landscape planting should incorporate native species, including those species known to provide foraging opportunities for breeding birds and nectar sources for invertebrates. Enhancements in the form of bird and bat boxes are also recommended. 18-2765 EXTENDED PHASE 1 SURVEY REPORT V1 SA 010319 Page 4 of 52 Table of Contents 1.Purpose INTRODUCTION of Document ................................ ......................................................................... 7 Terms of Instruction .............................................................................................................. 7 Report Limitations ................................................................................................................ 7 Documents Provided ............................................................................................................. 7 Qualifications ....................................................................................................................... 7 Site Description .................................................................................................................... 7 Aim of the Study ................................................................................................................... 8 2.
