Planning permission is currently being sought for a change of use of the barn to residential. During an initial visual inspection no evidence was found of a significant bat roost within the building. However, a low density of scattered bat droppings was found inside the building, along with evidence of a feeding perch, Therefore an evening emergence survey was carried out in July 2014. During the evening emergence survey, a single Natterer’s bat emerged from the building. As only a single bat emerged we can safely rule out the presence of a maternity roost in the building. The impact on the species will therefore be very low. However, a licence will be needed to permit the development, and a bat box will be required for mitigation. There was no evidence of use of the barn by breeding birds or barn owls. 5 Bat, Breeding Bird and Barn Owl Scoping Survey: The Barn, Knayton 2. Introduction MAB Environment and Ecology Ltd was commissioned to carry out a bat, breeding bird and barn owl scoping survey of The Barn, Knayton (central grid reference: SE436879). Knayton is a small village, immediately east of the A19, approximately 3.5miles north of Thirsk . The barn is situated to the east end of the village, bordering open fields. The location of the site is shown circled in Figure 1, below. Figure 1 Site location. Planning permission is currently being sought for change of use of the attached barn to residential. Proposal drawings have been requested and will be appended upon receipt. The report’s primary objective is to provide an impact assessment for the development on bats, define any necessary mitigation proposals, and to assess the requirement for a Protected Species Licence. A secondary objective is to assess potential impact on breeding birds. 6 Bat, Breeding Bird and Barn Owl Scoping Survey: The Barn, Knayton 3. Site Description The building inspected during the survey is shown within the red boundary on Figure 2. The building (shown in Photo 1 and Photo 2) is a recently constructed, two-storey, agricultural barn, currently used for storage. The Barn walls are constructed from wooden planks on a concrete breezeblock base. There is no wall cavity present. The roof is tiled with a modern composite material and is supported by wooden beams.

Methodology 4.1 A visual inspection of the barn was carried out by Emma Telfer GCIEEM, of MAB Environment & Ecology Ltd. Emma Telfer is an Ecology graduate who has received training in 2014 in surveying for bats and bat ecology. She has two years experience of bat emergence surveying for MAB. 4.2 The interior and exterior of the building was inspected during the day using halogen torches (500,000 candle power), ladders, and a flexible endoscope (a Sea Snake LCD inspection scope). All normal signs of bat use were looked for, including bats, bat droppings, feeding waste, entry and exit holes, grease marks, dead bats, and the sounds/ smells of bat roosts. 4.3 The buildings were assessed for their degree of potential to support roosting bats. This includes assessing the building design, materials and condition. The location of the site and the surrounding habitat were also assessed for value to bats. This includes proximity of the site to good bat foraging habitat such as woodland and water bodies and if the site is linked to such habitats by linear features like hedgerows, woodland edges or rivers which bats use to commute around the environment. 4.4 Bat roost records for a 2km radius around the site were commissioned from the North Yorkshire Bat Group. 4.5 Emergence surveys were carried out using 2 surveyors with ultra-sound detectors (Pettersson D240x, and BatBox Duet). The D240x detector was set to 10x expansion with manual triggering with an Edirol R09 WAV solid state recording device for the time expansion channel, with heterodyne output through the other channel. The Duet used heterodyne detection was set to 50 kHz. Time expansion recordings were analysed with BatSound software. 8 Bat, Breeding Bird and Barn Owl Scoping Survey: The Barn, Knayton Surveyors used were Matt Cooke ACIEEM and Matt Wingrove. Matt Cooke is a fully trained bat surveyor with 4 years experience with MAB Environment and Ecology Ltd. and holds a Natural England bat survey licence (Licence number: 2014/SCI/0237). Matt Wingrove is a Biology graduate, trainee bat worker and has worked for MAB in 2013 and 2014. 4.6 All signs of breeding bird activity and barn owl (Tyto alba) activity were looked for. Signs looked for included white droppings, often vertical down walls or beams; active nests and nesting materials; (birds flying into and out of barns: generally summer only); bird feathers, particularly swift (Apus apus), swallow (Hirundo rustica) and house martin (Delichon urbica), bird corpses, feeding waste (including pellets), and the sound/smell of birds. 5. Constraints Overhanging trees on the north elevation reduced visibility during the emergence survey. 9 Bat, Breeding Bird and Barn Owl Scoping Survey: The Barn, Knayton 6. Results 6.1 Desktop study Consultation with the Multi Agency Geographic Information systems for the Countryside website (MAGIC) revealed no designated sites of potential interest to bats within 2000m of the site. Bat records for a radius of 2km from the site were requested from North Yorkshire Bat Group and are included in Figure 3. No records of bats relate to the site itself. There are four recorded bat roosts in the local area. A Common pipistrelle roost was recorded at Ivy House, and Oak Dene and roosts of unknown species of bats occur at Oakdene and Water Hall Farm. Other species of bat recorded in the area are Soprano pipistrelle, Whiskered/Brandt’s bats and Myotis species. Figure 3: North Yorkshire Bat Group records. There are no records of barn owl roosts at of the site. 10 Bat, Breeding Bird and Barn Owl Scoping Survey: The Barn, Knayton Habitat description An aerial photograph illustrating land-use surrounding the site is shown in Figure 4, below. Land use surrounding the site is predominantly arable with scattered trees and hedges along field boundaries and in gardens
