Intertidal Monitoring of Sabellaria Reef in Cardigan Bay Special Area of Conservation (SAC) 2008 dataset https://portal.medin.org.uk/portal/start.php?tpc=007_NRW_DS115072 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) is therefore required to report on a regular basis on whether features are in favourable conservation status. Honeycomb reef worm Sabellaria alveolata is a sedentary, tube-dwelling polychaete most commonly found on rocky substrata in the lower shore and shallow subtidal zones of marine and estuarine areas. The honeycomb reef worm is a UK BAP Priority Habitat (BAP habitats are now Habitats of Principal Importance/Priority Habitats). In Cardigan Bay SAC specific areas of interest include the biogenic Sabellaria reef. Sabellaria reef is considered vulnerable to coastal development, sea defence construction and heavy trampling. The purpose of this data capture was to re-survey the quadrat monitoring sites established in 2007. The descriptive transect surveys are not repeated in 2008. Data quality and confidence is considered high as all survey completed by professional and experienced marine field surveyors. 20100331
