| GES description | D6 Sea-floor integrity/D1 Benthic habitats | Impacts of human activities do not result in significant damage to the physical substrate and the biological structures on the seabed and deterioration of associated biological communities. The special habitat designated as endangered or vulnerable at the national level or by regional agreements (Bucharest Convention) and European legislation (the Habitats Directive) is effectively conserved by appropriate national and regional mechanisms |
