EUNIS habitat type hierarchical view (marine version 2022 & terrestrial version 2021)
The EUNIS habitat classification review is on-going. Four groups are pending review: Inland waters, Wetlands, Constructed, industrial and other artificial habitats and Complexes.-
M : Marine benthic habitats (MA-MG)
-
MA1 : Littoral rock
-
MA11 : Arctic littoral rock
-
MA12 : Atlantic littoral rock
-
MA121 : Lichens or small green algae on Atlantic supralittoral and littoral fringe rock
-
MA122 : Mytilus edulis and/or barnacle communities on wave-exposed Atlantic littoral rock
-
MA123 : Seaweed communities on full salinity Atlantic littoral rock
-
MA124 : Mussel and/or barnacle communities with seaweeds on Atlantic littoral rock
-
MA1241 : Pelvetia canaliculata and barnacles on moderately exposed littoral fringe rock
-
MA1242 : Fucus spiralis on full salinity exposed to moderately exposed upper eulittoral rock
-
MA1243 : Fucus vesiculosus and barnacle mosaics on moderately exposed mid eulittoral rock
-
MA1244 : Fucus serratus on moderately exposed lower eulittoral rock
-
MA12441 : Fucus serratus and red seaweeds on moderately exposed lower eulittoral rock
-
MA12442 : Fucus serratus and under-boulder fauna on exposed to moderately exposed lower eulittoral boulders
