INTRODUCTION It is proposed to add a two-storey extension to the existing house at Little Poppins, Venterdon, PL17 8PD. This extension would involve the removal of the roof of the existing two-storey extension and the demolition of the existing rear porch and utility. The OS Grid reference of the site is SX 35747 74853. Pan Ecology was commissioned by Mr and Mrs Fewell in May 2021 to carry out a visual bat and nesting bird survey to inform a planning application. Bats and nesting birds are legally protected (see Appendix 1). 2. SURVEY METHODOLOGY The survey area was defined as the roof of the property, as indicated in Figure 1. An assessment of the suitability of the survey area and surrounding habitats to support bats and nesting birds was made. A detailed search of the interior and exterior of the structure was carried out using a high powered torch to illuminate all areas thought suitable for bats and nesting birds. Any accessible cracks and crevices were investigated with the use of a torch and endoscope where neccessary. The survey involved looking for bats and nesting birds and for evidence of their use, including droppings, pellets, staining, liming, feathers and feeding remains. Survey details are shown in Table 1. Table 1 - Survey details Date Type of survey Personnel - bat licence Weather conditions number 21.05.21 Visual survey Dr Polly Couldrick Dry, cloudy, breezy. Shona McCombie Temp 10°C 2021-52512-CLS-CLS The survey methodology adopted follows the guidance given in ‘Bat Surveys for Professional Ecologists – Good Practice Guidelines’ (Collins, 2016) and ‘Barn owl survey methodology and techniques for use in ecological assessment’ (Shawyer, 2011). Impact assessment and mitigation follows the guidance provided by CIEEM (2018) and the ‘Bat Mitigation Guidelines’ (Mitchell-Jones, 2004). Potential bat roosts identified during the visual inspection of the building were categorised as to their suitability in accordance with the Bat Conservation Trust’s (BCT) Good Practice Guidelines (Collins, 2016) as described below: 3 • Negligible: negligible features with potential to support roosting bats. • Low: one or more features with potential to support individual bats on an occasional basis. Unlikely to support large numbers of bats. • Moderate: one or more features with potential to support roosting bats but unlikely to be of high conservation status. • High: one or more features with potential to support large numbers of bats on a regular basis. 3. SURVEY RESULTS 3.1 Habitat description The property, Little Poppins, is located in a residential area in Venterdon, Cornwall. The surrounding landscape is dominated by mixed agriculture with traditional hedges and pockets of woodland. The nearest Special Area of Conservation (SAC) is the Plymouth Sound and Estuaries SAC (c. 8.7km to the south east) and is designated for its marine features. Greenscoombe Wood Site of Special Scientific Interest (SSSI) and Hingston Down Quarry and Consols SSSI are the two closest SSSIs to the property (c. 3.8km and c. 5.7km respectively). Greenscoombe Wood SSSI is designated for the botany and invertebrate assemblages, notably the nationally endangered Heath Fritillary butterfly (Mellicta athalia) and two nationally rare plant species, Bladder-seed (Physospermum cornubiense) and Toadlflax- leaved St John’s Wort (Hypericum linarifolium). Hingston Down Quarry and Consols SSSI is designated for its geology. Little Poppins is surrounded by ancient woodland with pockets of this habitat falling within c. 1.4km to c. 4.9km in all directions; Great/Watergate Wood, Leigh Wood, Clitters Wood and Quarry Wood are among those closest to the property. The farmland, hedges and woodland habitat surrounding Little Poppins provide good foraging habitat for bats. Little Poppins is a rendered stone house. The main roof of the house, porch and utility have no roof voids with vaulted ceilings throughout. The sections of roof to be removed are on the northern elevation and include a slate roof over an existing bedroom and bathroom, a plastic roof over the rear porch and a slate roof over the utility room (Figure 1). The facias are all in good condition although there are some lifted tiles across roofs A and C. 4 A B C Figure 1 – Roofs due for removal under the current plans - The slate roof over an existing bedroom and bathroom (A) a plastic roof over the rear porch (B) and a slate roof over the utility room (C). 3.2 Visual bat survey results There are no roof voids at Little Poppins and no evidence of bats was found within the house. Due to a number of lifted tiles across roofs A and C (Figure 1) there were potential bat access points to the space between the slates and the membrane. There were no gaps under the tightly fitting facias or around the plastic roof of the rear porch (Figure 1, B). The potential bat roosting areas under the slates could not be visually surveyed and thus absence of bats could not be established. Therefore, a further survey of roofs A and C will be required to confirm absence. Little Poppins has been assessed as having low bat roost potential (see section 2) therefore one emergence survey at dusk is required to confirm absence. 3.3 Nesting bird survey results There was no evidence of nesting birds either inside or outside of the dwelling. 5 4. RECOMMENDATIONS 4.1 Bats As absence of bats could not be determined during the assessment, a further survey is required to confirm absence. It is recommended that one emergence survey at dusk is carried out between May and August. If absence is confirmed, a report will be produced to reflect the situation. However, if bats are found, then a second emergence survey at dusk should be carried out between May and September (with two weeks between surveys and at least one survey event between May and August). A mitigation statement would then need to be prepared and submitted with the planning application detailing how the population of bats is to be maintained in a favourable conservation status and may detail specific timings of works and provision of bat access and roosting space. The works would also then be subject to obtaining a European Protected Species (EPS) license once planning approval has been granted with mitigation requirements designed upon completion of the surveys. Only an experienced bat ecologist can undertake this work. To minimise delays it is recommended that you consult with a specialist bat ecologist at the earliest opportunity. 4.2 Nesting Birds No evidence of nesting birds nests were found and it is considered unlikely that any evidence was overlooked. No further surveys for nesting birds are required. As ecological features can change over time it is recommended that this report is valid until 21st May 2022. 6 5. REFERENCES BCT (2009).
