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
-
MA4 : Littoral mixed sediment
-
MA41 : Arctic littoral mixed sediment
-
MA42 : Atlantic littoral mixed sediment
-
MA43 : Baltic hydrolittoral mixed sediment
-
MA44 : Black Sea littoral mixed sediment
-
MA45 : Mediterranean littoral mixed sediment
