MARINE ECOSYSTEMS – HABITAT TYPES AND GROUPS OF HABITAT TYPES REFERRED TO IN ARTICLE 5(1) AND (2) The list below includes the marine habitat types referred to in Article 5(1) and (2), as well as seven groups of those habitat types, namely 1) seagrass beds, 2) macroalgal forests, 3) shellfish beds, 4) maerl beds, 5) sponge, coral and coralligenous beds, 6) vents and seeps and 7) soft sediments (not deeper than 1 000 metres of depth). The relation with the habitat types listed in Annex I to Directive 92/43/EEC is also presented. The classification of marine habitat types used, differentiated by marine biogeographical regions, is made according to the European nature information system (EUNIS), as revised for the marine habitats typology in 2022 by the EEA. The information on the related habitats listed in Annex I to Directive 92/43/EEC is based on the crosswalk published by the EEA in 2021 .
