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. Rocky reefs (hard substrata) are of considerable conservation importance due the high diversity of the communities they support and, as such, are included under Annex 1 of the EU Habitats Directive (92/43/EEC) (Hill et al. 1998). They are an abundant feature of the UK coastline, especially on western coasts where exposed bedrock predominates. In some areas, the substratum may be composed entirely o f bedrock whilst on less steeply shelving / gently shelving shores, large boulders, cobbles, gravel, sand and mud may be present (Hill et al., 1998). Rocky reefs are extremely variable in terms of their structure and the communities they support with reef communities being influenced by the type of rock and the microhabitats available, sediment availability, degree of shelter, shore height, and temperature regime. Communities in exposed areas are usually dominated by sponges, anemones and foliose red algae with ascidians, delicate filamentous algae and fan worms being more common in sheltered areas (JNCC, 2005).

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The following procedure was employed to compile the species richness of the boulders: a measure of the extent of the underboulder biotope community was attempted with the surveyors hopping in and out of the boat to carry out the survey of extent, boulders were chosen along the same shore height (MLW - MSLW) and within close proximity to each other (where possible), boulders were only selected if they fitted within a 0.5 m x 0.5 m quadrat. These intermediate sized boulders are known to carry the highest diversity, with smaller stones being overturned too often to acquire a stable community whilst larger boulders develop a single-species dominance (Liddiard et al 1989), a GPS point was taken of each boulder, a photograph was taken of the boulder upper surface the n a species list taken, The boulder was then turned, photographed and a species list taken from the underside of the boulder. All survey completed by professional and experienced marine field surveyors. Data quality and confidence considered high. |
