As part of the UK's commitment to the 1992 UNEP Convention on Biological Diversity there have been a number of coordinated initiatives to identify those habitats which may be under threat in the UK, and to establish plans to reduce those threats and thereby maintain biodiversity. The UK Biodiversity Action Plan (BAP) is now one of the main focuses of that work. It provides detailed proposals for a number of species, species groups and habitats requiring urgent conservation action. In addition to this the Habitats Directive (1992) requires the establishment of a European network of important high-quality conservation sites, Special Areas of Conservation (SACs). The Habitats Directive identifies Reefs as a major category of habitats that should be considered for inclusion in SACs
. Tidal rapids not only forms part of the reef environments classification but is also highlighted as an important site under the UKBAP habitats list. Tidal rapids is used to describe a broad range of high energy environments including deep tidal streams and tide-swept habitats. JNCC’s Marine Nature Conservation Review (MNCR) defined rapids as ‘strong tidal streams resulting from a constriction in the coastline at the entrance to, or within the length of, an enclosed body of water such as a sea loch. Depth is usually shallower than five metres. The data collected during this survey is being used to help define the conservation objectives for the cSAC reef features in Wales and to inform management of this feature. One of the actions listed in the Habitat Action Plan for tid
al rapids is to, complete survey and recording of the extent, quality and composition of the habitats and communities of tidal rapids.

dataset
Survey methods were based on the standard Marine Nature Conservation Review (MNCR) techniques using in-situ identification of conspicuous species and description of habitat and community characteristics. Subtidal and intertidal components of the fieldwork were carried out separately. Survey data was recorded immediately on standard MNCR recording forms. Confidence in this dataset is high because it was undertaken by experienced surveyors. Previous surveys have been undertaken in this areas, by various parties and include some detail of the 'Tidal Rapids' and reef systems. These include surveys carried out by former Countryside Council for Wales (CCW), JNCC, Seasearch and various others.
