Countryside Council for Wales (CCW) developed a programme of intertidal monitoring work across Wales during 2004 and 2005. These surveys were managed and implemented for CCW by the Institute of Estuarine and Coastal Studies (IECS, University of Hull). These projects focused on a wide range of sensitive habitats such as Zostera, muddy gravels, caves, rock pools, algal dominated rocky shores, Sabellaria reefs, under-boulders, and various rare habitats and species. Aquatic Survey and Monitoring Ltd. (ASML) have been contracted by CCW to continue development and management of the intertidal monitoring programme for each marine SAC for the period 2006 to 2011, working as a team with CCW HQ and CCW Regional staff.
