Metadata: Intertidal Monitoring of Sabellaria Reef in Cardigan Bay Special Area of Conservation (SAC) 2008
Abstract:
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.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Surveys of Sabellaria reefs in the SAC were carried out for CCW in 2004 (Boyes et al. 2008). Additional mapping of Sabellaria reef extent at Aberaeron was carried out by CMACS Ltd. (sub-contracted by Atkins Ltd.) In August 2006 as part of an Environmental Assessment for proposed Aberaeron North Beach Coastal Defence Work (unpublished data provided by Atkins Ltd.). In 2007, ASML and CCW further developed Intertidal SAC monitoring methodologies for monitoring the Sabellaria reefs and monitoring sites were established and surveyed in May 2007 (Moore 2009).The extent and measure of the quality of the Sabellaria reef was evaluated using a GPS track and quadrat surveys, respectively. Sabellaria density, physical attributes and other conspicuous species were recorded from replicate quadrat stations to provide a repeatable method of evaluation. |
