Pembrokeshire Marine / Sir Benfro Forol Special Area of Conservation (SAC) Grey Seal (Halichoerus grypus) Monitoring 2005 dataset https://portal.medin.org.uk/portal/start.php?tpc=007_NRW_DS87116 The Habitats Directive establishes that the management of Special Areas of Conservation (SACs) should aim to achieve the favourable conservation status of habitat and species features listed within its Annex I and Annex II. For SACs in Wales, the former Countryside Council for Wales (CCW), now part of Natural Resources Wales (NRW), is therefore required to report on a regular basis on whether features are in favourable conservation status. Grey seals (Halichoerus grypus) are among the rarest seals in the world: the UK population represents about 40 percent of the world population and 95 percent of the EU population. Pembrokeshire Marine / Sir Benfro Forol SAC is home to one of the largest populations of grey seals around the west coast of the UK. The purpose of this data capture was to record, document and report indicators of the condition of grey seals within the SAC. In addition to this, monitoring is also used to document and report on the impact of human activities, assessment of supporting habitat, and used in the estimations related to the population and structure (age and sex). The data collected will contribute to an estimate of whole site (SAC) production using indices developed following the 1992-94 seal census. 20061231
