Introduction This document contains Natural England‟s formal advice for the Lyme Bay and Torbay candidate Special Area of Conservation (cSAC) given under Regulation 35(3) of The Conservation of Habitats and Species (Amendment) Regulations 2012. It supersedes the previous draft conservation advice for Lyme Bay and Torbay cSAC. It also supersedes draft advice on the Poole Bay to Lyme Bay proposed Special Area of Conservation (pSAC). As a result of the 2009/10 public consultation on the Poole Bay to Lyme Bay pSAC, the Lyme Bay component was renamed Lyme Bay and Torbay; and the Poole Bay component was renamed Studland to Portland. Lyme Bay and Torbay was formally submitted by the Government to the European Commission as a cSAC on 20th August 2010. The European Commission adopted the site in November 2011 and it became a Site of Community Importance (SCI). The Government has six years from the date of adoption to designate the site as a Special Area of Conservation (SAC). The cSAC is subject to full protection under the Habitats Directive2 (transposed through the Conservation of Habitats and Species (Amendment) Regulations 20123 and the Offshore Marine Conservation Regulations (Natural Habitats, &c.) (Amendment) Regulations 2012 (herein referred to as the „Habitats Regulations‟). Amongst other things, the Habitats Regulations place an obligation on relevant authorities4 to put in place measures to protect sites from damage or deterioration. This document fulfils Natural England‟s duty under Regulation 35(3)5 of The Habitats Regulations, to advise relevant authorities as to (a) the conservation objectives for Lyme Bay and Torbay: and (b) any operations which may cause deterioration of natural habitats or the habitats of species, or disturbance of species, for which Lyme Bay and Torbay cSAC has been designated. The advice is based on best available information at the time of writing and will be reviewed to take account of new information. This formal conservation advice constitutes one element of Natural England‟s advisory role in relation to this site. Relevant authorities can use the information to explore and put in place management measures (if required) and competent authorities6 can fulfil their duties under the Habitats Regulations in making the necessary determinations on the impact of activities on the site. If relevant authorities or competent authorities require any further advice, they are not limited to taking account of Natural England‟s formal conservation advice contained here, and would be expected to make further enquiries as required in order to make determinations or implement management measures. Further information/reference should be made to the SAC Selection Assessment Document7 for Lyme Bay and Torbay cSAC. An independent review8 of Natural England‟s marine SAC selection process carried out in 2011 made a number of recommendations as to how Defra and Natural England should 2 Council Directive 92/43/EEC of 21 May 1992 on the conservation of natural habitats and of wild fauna and flora 3 http://www.legislation.gov.uk/uksi/2012/1927/introduction/made 4 as defined under Regulation 6 of The Conservation of Habitats and Species (Amendment) Regulations 2012 5 http://www.legislation.gov.uk/uksi/2010/490/regulation/35/made 6 as defined under Regulation 7 of The Conservation of Habitats and Species (Amendment) Regulations 2012 7 http://www.naturalengland.org.uk/Images/LBT-sad_tcm6-21650.pdf 8 http://www.defra.gov.uk/publications/files/pb13598-graham-bryce-independent-review-marine-sacs-110713.pdf Page 5 of 86 Lyme Bay & Torbay cSAC_ NE Reg 35 conservation advice_Version 2.2 modify their approach to future evidence based work. This resulted in Natural England adopting the Government Chief Scientific Adviser‟s (GCSA) guidelines9 on using evidence, through the development of a suite of Evidence Standards10. Implementation of these standards has included Natural England working with JNCC to develop a protocol11, which has been subject to independent expert review, setting out the processes and requirements for the development of conservation advice packages, to ensure that these fully comply with the GCSA‟s guidelines. Whilst the conservation advice provided here was developed prior to the finalisation of the protocol, it has been assessed for compliance with the protocol and a detailed report can be found on our website12. During 2011/12 Government instigated a review of the implementation of the Habitats and Wild Birds Directive.
