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
-
MA5 : Littoral sand
-
MA6 : Littoral mud
-
MB1 : Infralittoral rock
-
MB11 : Arctic infralittoral rock
-
MB12 : Atlantic infralittoral rock
-
MB121 : Kelp and seaweed communities on Atlantic infralittoral rock
-
