oost is defined as any structure or place which is used for shelter or protection, irrespective of whether or not bats are resident. 4.10 Should a bat roost be present then a Natural England European Protected Species (EPS) Licence to fell the tree will be required. Bat Mitigation Strategy 4.11 Given the urban location of the Site and the type of the PRFs, it is anticipated, that should a bat roost be present within T5, it is likely to be of a common and widespread species that utilises urban areas, such as common pipistrelle or soprano pipistrelle, as opposed to the UKs rarer bats. The mitigation and compensation for common and widespread species (such as common pipistrelle and soprano pipistrelle) is well understood, well-practiced and considered generally deliverable. 4.12 The presence of a bat roost within T5 has not been confirmed. However, within the Site there exists opportunity to compensate for the removal of tree T5. The proposals would allow for bat tubes or lifted/raised weatherboarding to be installed on the eastern or south-west facing aspect of the proposed studio building that is to be constructed on the eastern boundary of the southern garden. In this area, the mature trees provide sufficient shelter from both weather conditions and visitor disturbance, whilst also providing clear flight paths for entrance/exit. Alternatively, bat boxes could be installed within mature trees within the Site, which would provide a similar function as the PRFs that are present on T5. 4.13 The exact details of the bat mitigation and compensation would be determined by the results of the further surveys and if a bat roost is present then mitigation and compensation would be secured by a European Protected Species licence. nest (distance to be decided at the ecologist's discretion). This buffer must remain intact until is has been confirmed that that the young have fledged, and the nest is no longer in use. 4.17 The tree housing the current bird boxes is not scheduled for removal or disturbance. New tree planting is proposed within the Site which will provide additional nesting opportunities within the Site in the long term. In addition, wildflower meadow is proposed which will support a greater abundance and more diverse invertebrate assemblage, thereby increasing food provision for birds. Enhancements 4.18 A number of additional measures are proposed within the scheme, which will further enhance the ecological value of the Site: • Planting of scattered trees in the southern garden, creating a woodland feel, providing areas of shading; • Wildflower meadow planted in the eastern side of the southern garden; and • A wildflower seed mix also used to create a green roof on the studio building proposed to be built in the south garden. • Extra bird boxes installed on additional, suitable trees within the southern part of the Site. 4.19 These enhancement measures, along with the mitigation and compensation measures outlined above would significantly increase the ecological value of the Site. 4.14 Based on the above premise, if a bat roost is present within T5, then bat mitigation and compensation can be delivered within the Site and would be secured by EPS licence. Therefore, the further survey work, outlined in 4.8, could be conditioned via a Grampian (precommencement) planning condition as part of any planning application granted for the Site, without jeopardizing the favourable conservation status of any bat species using T5 as a bat roost (if determined as present by the conditioned surveys). This is reasoned in line with guidelines put forward by the British Standards Institute (BSI) 5 and CIEEM 6 . Birds 4.15 The proposals have the potential to harm nesting birds via the removal of scattered shrubs and one lime (T5). Disturbance of works could also have an effect on nesting birds, works are proposed within 5m of two nesting bird boxes found on the large horse chestnut tree (T2), which are suitable for both finches, and sparrows and tits. 4.16 In order to mitigate for this any of the vegetation to be removed and any construction works occurring within the southern are of the Site should be carried out outside the nesting bird season (from March-August inclusive). Should it be necessary to remove conduct work during the bird nesting season, the area must be checked in advance for the presence of bird's nests by a suitably competent person. If there is no evidence of breeding birds, the works can, starting no later than 48 hours after inspection, be carried out. If active nests are identified, any of the vegetation clearance must cease and an appropriate buffer zone must be established around the 5 BSI (2013).

5 Conclusion Appendix 1 Site Plan 5.1 The Site is of low ecological value, supporting a range of urban typical habitats: amenity grassland, several mature trees, a small area of shrubbery and ornamental planting, and several formal lines of trees, with the grounds intersected with hardstanding. 5.2 A tree (T5) was found with the potential to support a bat roost. One survey of this tree has been undertaken, however further surveys are required to determine if this tree supports a bat roost. This tree is scheduled to be removed as a result of the proposals and therefore a bat mitigation strategy, including the conditioning of further bat surveys, has been outlined. 5.3 Migration and compensation has been outlined for all habitats and species to be effected by the proposals. Enhancement measures provided to increase the ecological value of the site.
