Intertidal Monitoring of Rockpools in Pembrokeshire Marine Special Area of Conservation (SAC) 2007 dataset https://portal.medin.org.uk/portal/start.php?tpc=007_NRW_DS111177 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 Countryside Council for Wales (CCW) was therefore required to report on a regular basis on whether features are in favourable conservation status. Pembrokeshire Marine Special Area of Conservation (SAC) was selected for eight Habitats Directive Annex I habitat types and five Annex II species. The SAC is considered to be one of the best areas in the UK for marine reef habitats, a category within the Annex I list. High habitat and biological diversity is of great importance throughout the site, particularly the best documented reefs habitat in the Milford Haven ria-estuary. This dataset includes the results of a survey of intertidal rockpools at Pen-y-Holt on the Castlemartin peninsula. 20090201
