Postcode / OS grid ref: ST11 9DL (NGR: SJ967424) Issue No: Final issue (1) Date issued: February 2017 Report written by: Mark Weston BSc (Hons), GradCIEEM, AMRSB Principal Ecologist Surveyor capability Ecological assessment and report preparation has been conducted by a Natural England licensed bat Ecologist (CLS00836 – Level 2) and member of the Chartered Institute of Ecology and Environmental Management (MCIEEM), and an associate member of the Royal Society of Biology (AMRSB). The ecologist has a First Class Honours degree in Conservation Biology, and Vice Chancellors award for academic excellence. He has undertaken protected species surveys for over seven years, and is actively involved in scoping, presence/absence surveys and Natural England EPS licence applications with regard to planning and the law. The actions of the surveyor on site and during the production of written reports are undertaken in accordance with the Code of Professional Conduct for the Chartered Institute of Ecology and Environmental Management (CIEEM). 2 Field House Farm ST11 9DL Preliminary Roost Assessment Final Issue (1) – February 2017 NON-TECHNICAL SUMMARY Report rationale 1. Charnia Ecology was commissioned to undertake a Preliminary Roost Assessment (PRA) on behalf of the applicant Mr. Simon Edwards of Field House Farm, Dilhorne Road, Stoke-on-Trent ST11 9DL (NGR: SJ993424). 2. The objective of the report is to identify the presence of protected bat and bird species within the proposed application area, and to recommend any further actions/mitigation measures required as a result of the survey findings. The survey was conducted on the 1st February 2017 by a Natural England [class 2] licensed bat ecologist and member of the Chartered Institute of Ecology and Environmental Management (CIEEM). Proposed works 3. It is understood that the proposed planning application considers the conversion of the main barn building into a dwelling which is attached to the existing farmhouse building. The site currently provides residential care and accommodation for vulnerable adults integrating back into the community. Site description 4. Field House Farm is situated in Green belt on Dilhorne Road between Forsbrook and Dilhorne. The site comprises of a Grade II listed Farmhouse with associated farm buildings, hard standing and gardens. In context to the wider landscape, the application area is surrounded by open agricultural farmland, gently undulating hills, hedgerows, and intermittent blocks of ancient woodland. 5. The building inspection considered both the structure proposed for redevelopment (B2) whilst also assessing associated structures considered to be within the Zone of Influence (Farmhouse B1 and Farm building B3). st 6. Evidence of roosting bats, by way of droppings and possible feeding remains, were recorded in the 1 floor area of B2; whilst droppings were also recorded in the roof void of the attached Farm house B1, although exact status is not clear. 7. Evidence of a small colony of nesting Barn swallow was recorded in the ground-floor area of B2. No evidence of Barn owl was recorded. Survey constraints 8. There were no survey constraints encountered during the building inspection, although some of the floor area in B2 were considered as being unstable. Impact assessment BATS BIRDS BARN OWL Main structure proposed for development B2 Building HIGH HIGH LOW Associated structures within the Zone of Influence B1 Farmhouse HIGH LOW NEGLIGIBLE B3 Building LOW TO MODERATE NEGLIGIBLE MODERATE 3 Field House Farm ST11 9DL Preliminary Roost Assessment Final Issue (1) – February 2017 9. At this juncture, it is speculated that two species of bat may be roosting onsite. Common pipistrelle is considered to be most likely species to utilize the dimensions of the roof void in B1, whilst the voluminous roof void area inside B2 provides excellent potential for void dwelling Brown Long-eared bat. Designated sites 10. As the proposed development retains the existing size and physical form of the existing building (s) footprint (with no additional land up-take considered), NO impact on any designated sites in the surrounding landscape is predicted. Recommendations Bats 11. As both building B1 (proposed for conversion) and the attached Farmhouse (within the zone of influence) found evidence of roosting bats, it is recommended that additional Phase 2 survey activity surveys are required to establish exact roost status and foraging and commuting habitat onsite. These should include a minimum of 2 x emergence and 1 x re-entry surveys, which should be carried out between May and September. 12. The findings from the Phase 2 survey report will then determine the appropriate level of mitigation, and whether or not a Natural England License will be required in compliance to current conservation legislation and planning policy guidelines. 13. It is understood that the client wishes to commence with remedial re-pointing structural repair works, whilst the planning application is under consideration. Should this be the case, then any re-pointing of brickwork should be carried out at ground-floor level only. NO re-pointing should be undertaken to any external brick-work >3.5m in elevation, until Phase 2 activity surveys have been completed. Birds 14. All birds are protected under the Wildlife and Countryside Act 1981 (as amended). Mitigation should therefore give consideration to a small colony of nesting Barn Swallow in the ground-floor area of building B1. It is understood that the client wishes to commence with remedial repair works within this ground-floor area, whilst the main planning application is under consideration. It is therefore recommended that all doors, windows and ingression points are sealed off in-order to exclude Barn Swallow from this building before summer uptake and re-instated in B3 (see recommendations). No evidence of Barn owl was recorded and NO further recommendations are considered with regard to this species. 4 Field House Farm ST11 9DL Preliminary Roost Assessment Final Issue (1) – February 2017 Contents NON-TECHNICAL SUMMARY 1.
