PEMBROKSHIRE SAC REGULATION 33 ADVICE SUMMARY: PLEASE READ THIS FIRST This document contains CCW’s advice issued under Regulation 33 of the Conservation (Natural Habitats, &c.) Regulations 1994, for the Pembrokeshire Marine Special Area of Conservation (SAC), namely conservation objectives and advice on operations. It also includes an explanation of the purpose and format of CCW’s “Regulation 33 advice”. This latest version of the Regulation 33 package has been revised to improve consistency across the marine SACs in Wales. The intent of the conservation objectives and of the advice on operations which may cause deterioration or disturbance to the feature is the same as in previous versions. The Conservation Objectives are now shorter and more generic but there has been no change in what is considered to represent Favourable Conservation Status. Section 1 is a brief introduction to the legal context for Regulation 33 advice. Section 2 explains in more detail the legal basis and practical requirements for setting conservation objectives for Natura 2000 sites, as understood by CCW. It also explains the legal and practical basis of the operations advice. Section 3 contains a brief overall description of Pembrokeshire Marine SAC, current operations taking place with the SAC and information on modifications as a result of human activity. Section 4 describes habitats and species for which the Pembrokeshire Marine SAC has been selected as an SAC as well as why they are considered important. The information is presented using the same headings as those used to describe the conservation objectives so that useful underpinning information in support of these objectives can easily be referenced. Section 5 contains CCW's advice as to the conservation objectives (Regulation 33(2)(a)) for the features for which the site has been selected as a SAC. This includes a vision statement which is a descriptive overview of what needs to be achieved for conservation on the site. It brings together and summarises the Conservation Objectives into a single, integrated statement about the site. Section 6 contains CCW’s advice as the operations which may cause deterioration or disturbance of the habitats and species for which the site has been selected (Regulation 33(2)(b)). This is provided to assist the relevant authorities and others in understanding the implications of the designation of the site and the requirements of the Habitats Regulations and government policy towards it. The Appendices provide a glossary of terms, a list of other types of protected areas within the SAC and more detail on the elements of Favourable Conservation Status. Other background information such as lists of additional species and habitats of particular note (e.g. species and habitats subject to Biodiversity Action Plans or threatened and declining species and habitats identified by the OSPAR Commission) and the variety of biotopes associated with Annex 1 features may be added in due course. The Maps show the boundaries of the SAC, the location of other protected areas which occur within the SAC, and give an indication of the location of features for which the site was designated. Further maps, for example of adjacent designated areas or giving an indication of the location of habitat components (e.g. types of reef or types of mudflat and sandflat), may be added in due course. PEMBROKESHIRE Marine Febuary 2009 1 INTRODUCTION The 1992 EC Habitats Directive 1 aims to help conserve the diversity of habitats and species across the European Union. It represents one of the ways in which EU member states are fulfilling the commitments they made at the “Earth Summit” in Rio de Janeiro in 1992, for the conservation of the Earth’s biological diversity2. The Habitats Directive requires member states to take a variety of measures aimed at the conservation of biodiversity. These measures include the designation of
