North West Anglesey tidally exposed seabed and shores (2003-2004) dataset https://portal.medin.org.uk/portal/start.php?tpc=007_NRW_DS87132 As part of the UK's commitment to the 1992 UNEP Convention on Biological Diversity there have been a number of coordinated initiatives to identify those habitats which may be under threat in the UK, and to establish plans to reduce those threats and thereby maintain biodiversity. The UK Biodiversity Action Plan (BAP) is now one of the main focuses of that work. It provides detailed proposals for a number of species, species groups and habitats requiring urgent conservation action. In addition to this the Habitats Directive (1992) requires the establishment of a European network of important high-quality conservation sites, Special Areas of Conservation (SACs). The Habitats Directive identifies Reefs as a major category of habitats that should be considered for inclusion in SACs. Tidal rapids not only forms part of the reef environments classification but is also highlighted as an important site under the UKBAP habitats list. Tidal rapids is used to describe a broad range of high energy environments including deep tidal streams and tide-swept habitats. JNCC’s Marine Nature Conservation Review (MNCR) defined rapids as ‘strong tidal streams resulting from a constriction in the coastline at the entrance to, or within the length of, an enclosed body of water such as a sea loch. Depth is usually shallower than five metres. The purpose of this data capture was to assess the features in North West Anglesey to help inform and define conservation objective and decisions regarding their protection and management. 20040305
