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
-
MA2 : Littoral biogenic habitat
-
MA3 : Littoral coarse sediment
-
MA31 : Arctic littoral coarse sediment
-
MA32 : Atlantic littoral coarse sediment
-
MA33 : Baltic hydrolittoral coarse sediment
-
MA34 : Black sea littoral coarse sediment
-
MA35 : Mediterranean littoral coarse sediment
