2003-2004 Lundy European Marine Site Sublittoral Monitoring dataset https://portal.medin.org.uk/portal/start.php?tpc=010_7eadf985c507423c8e0bed09bc8abc6c This Aquatic Survey and Monitoring Limited (ASML) project was commissioned to assess the interest feature - Reefs (subtidal), within the cSAC, by surveying several sub-features of Lundy's reefs, identified as ecologically important components. These components, outlined in the regulation 33 package, include; kelp forest communities, subtidal bedrock and stable boulder communities and Eunicella (Pink Sea Fan) characterised reef, all to be surveyed by 'drop-down video' in order to establish a baseline, from which in the future, an assessment of the target; 'No decrease in the distribution, extent and range of biotopes from a baseline' will be made. Some biotopes and other structural aspects of these same components were also to be surveyed by quantitative diving techniques, to establish a baseline against which an assessment of the target, 'Species composition: no significant deviation from baseline' will be made. 20041231
