Appendix 2: Legislation 21 Summary Hopkins Ecology Ltd was appointed by Brown & Co on behalf of Mr Maggs to prepare an ecological assessment for a semi-derelict cottage and its grounds in a rural location near Aldringham-cum-Thorpe, which is roughly 2.2km inland from Thorpeness. It is proposed that the cottage will be demolished and two new dwellings built. Key components of the work are bat surveys of the cottage and any other relevant structures, and reptile surveys. The grounds of the cottage are ‘overgrown’, mainly with bracken and scrub of bramble and young sycamore. There are a few taller sycamore along the south boundary. Bat surveys comprised two dusk surveys and a dawn survey, each with multiple surveyors. The key findings are: • A single Natterer’s was seen to emerge through a missing window on 2 July 2018; a brown long-eared was suspected to have emerged from a hole in the roof on the same date. • No bats were seen to return during the dawn survey of 20 July 2018. • A brown long-eared was strongly suspected to have emerged on 14 August 2019. It is concluded that the cottage is used as a casual roost by singletons of Natterer’s and brown long-eared bats. Notwithstanding legal protection of the roost it is thought that a small roost of two widespread species would be of value only at the local scale. It is considered that the scheme is appropriate for low impact licensing, and it is suggested at this stage that the mitigation should comprise: • Bat boxes erected on trees within the Site, probably close to the south boundary, prior to demolition. These would provide alternate roost sites during demolition and other works. • The completed cottage should include bat boxes within the structure as either integral or external boxes. These would provide long-term roosting areas following completion of the scheme. Following planning consent a suitably licensed ecologist should be appointed to oversee the mitigation works. Reptiles were not recorded by direct surveys, and specific mitigation is not required. However, during site clearance vigilance should be maintained and material removed by hand where possible. Other species of conservation concern scoped-in are nesting birds, hedgehogs and widespread but declining moths. These would be minor components of larger local populations. Site clearance should avoid the nesting bird season or otherwise be under a watching brief. Additional measures of value to wildlife within the completed should include landscaping with native plant species, bird boxes, and fences or hedging that allow hedgehogs access to the gardens within the completed scheme.

Introduction BACKGROUND 1.1 Hopkins Ecology Ltd was appointed by Brown & Co on behalf of Mr Maggs to prepare an ecological assessment for a semi-derelict cottage and its grounds. It is proposed that the cottage will be demolished and two new dwellings built. Key components of the surveys are bat surveys of the cottage and any other relevant structures, and reptile surveys. SITE CONTEXT AND STATUS 1.2 The Site is ~0.2ha in area and comprises a semi-derelict cottage and its grounds to the east of Church Lane, a quiet country lane. The location is rural, near Aldringham-cum-Thorpe, which is roughly 2.2km inland from Thorpeness. There is forestry to the east of Church Lane and a band of deciduous woodland to the west. It is in a rural location. LEGISLATION AND PLANNING POLICY 1.1 The following key pieces of nature conservation legislation are relevant to legally protected species (with a more detailed description in Appendix 5): • The Conservation of Habitats and Species Regulations 2017 (the Habitats Regulations); and • The Wildlife and Countryside Act, 1981 (as amended). 1.2 Also, the National Planning Policy Framework (DfCLG, 20181) requires local authorities to avoid and minimise impacts on biodiversity and, where possible, to provide net gains in biodiversity when making planning decisions. A substantial number of species are of conservation concern in the UK. A small number of these species are fully protected under the legislation listed above, but others in England are recognised as Species of Principal Importance under the Natural Environment and Rural Communities Act 2006 and reinforced by the National Planning Policy Framework. For these species local planning authorities are required to promote the “protection and recovery” via planning and development control. Examples include the widespread reptiles, skylarks and soprano pipistrelle and, brown long- eared bats. 1.3 Although the NPPF has an overarching aim of minimise impacts to biodiversity, the majority of species of conservation concern are not specifically recognised by legislation or planning policy. The level of protection afforded to these is undefined and should be considered within the overall aim of minimising impacts on biodiversity. 1 DCLG (2018) National Planning Policy Framework.

Methods DESK STUDY 2.1 The desk study comprised a formal data search from the local records centre and review of relevant data and information from other sources (Table 1). Table 1. Overview of desk study data sources. Source Information Suffolk Biodiversity Information 2km data search for designated sites and protected / Service priority species MAGIC Additional information on statutory sites, habitats of (https://magic.defra.gov.uk/) principal importance and wider countryside information PERSONNEL 2.2 The survey work was led by Dr Graham Hopkins CEnv MCIEEM, who holds full survey licences for bats and great crested newts. Present on all surveys were two other licenced bat ecologists with field assistants as necessary. WALKOVER SURVEY 2.3 A Site walkover was undertaken on 27 June 2018, when habitats were described according to the methods of JNCC (2010)2. BATS 2.4 The potential presence of bat roosts followed the methods of the Bat Conservation Trust (Collins, 20163). Trees were surveyed from ground level for their potential suitability for roosting bats, looking for gaps, cracks and other potential roost features. Buildings were assessed visually and in conjunction with a short ladder and endoscope: first, to determine the potential presence of any roost features; and second, for any direct evidence such as droppings. 2.5 Activity surveys were undertaken following Collins (loc. cit.) as described in the Results. REPTILES 2.6 Twenty artificial refugia were placed along the inside of the boundaries of the Site, by trampling bracken to ensure the refugia were at ground level. The refugia consisted of sections of bitumen roofing felt ~1m2 and were put in situ on 16 July 2018. The felts were left in place for approximately a month before the first survey visit was undertaken. A total of nine survey visits were made in suitable weather conditions (between 9 and 18°C with little or no wind or rain) to check the felts for basking or sheltering reptiles (Table 2). The methods are in accordance with current survey guidance (Froglife,19994). 2 JNCC (2010) Handbook for Phase 1 Habitat Surveys. Joint Nature Conservation Committee, Peterborough. 3 Collins, J.

The collapsed sheds to the south of the building made it unsafe to access or closely view the southern elevation of the cottage; access inside the cottage was not possible due to dense vegetation and the building being deemed unsafe to enter.
