Intertidal biotope mapping was carried out in order to determine the distribution and extent of seashore habitats, biological communities and species on the shores of Wales. Subtidal biotopes were predicted in HABMAP in order to act as a guide for marine scientists. The biotopes were converted to fisheries habitats in order to provide a means of assessing the sensitivity of benthic habitats to the effects of fishing gear types. The intertidal area consists of the whole of the welsh coastline between the limits of the tidal rise and fall. The subtidal area consists of Welsh water out to 12 nm offshore which are within the Southern Irish Sea i.e. sections around the Severn in the south and the Dee in the north are not included. HABMAP modelling has been re-run to include these areas in the south and north and these biotopes are due to be included in the fisheries habitats maps in 2010.

Intertidal biotopes will be updated in the long term (20 yrs) depending on resource availability. Subtidal biotopes are intended to be reviewed and updated via HABMAP as and when resources are available; if a significant amount of new data is collected that will make it a higher priority. All biotopes were converted to fisheries habitats (grouped according to their response to fishing gear types) by CCW and checked by expert judgement.

The intertidal biotope mapping was carried out by dedicated teams of trained staff from former Countryside Council for Wales (CCW) staff. the intertidal surveyors followed standard protocol and worked in with more and less experienced staff working together. Intertidal biotopes were mapped as part of CCW's intertidal field survey of Wales using Phase I methodology. Intertidal biotopes were mapped from 1996-2004 and converted to fisheries habitats between 2008 and 2009. Subtidal biotopes were predicted as part of the BIOMOR 5 HABMAP I and II project using modelled seabed data. Predictions and conversions into fisheries habitats in 2008 and 2009 using seabed survey data collected in 2005 and a variety of other data sources dating back to 1963. Spatial confidence scores of the subtidal habitat were produced alongside the biotopes. These were split in to areas of reasonable, low and poor confidence. Both the intertidal and subtidal conversions, from biotope to fisheries habitats, were checked using expert judgement. Fisheries habitats are produced from intertidal and subtidal biotope maps. These data layers will form part of a large project (Distribution of Fisheries Habitats and Fishing Activities to Special Areas of Conservation (SAC) features (Fisheries sensitivity maps and matrices), project 376).
