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
-
MB2 : Infralittoral biogenic habitat
-
MB21 : Arctic infralittoral biogenic habitat
-
MB22 : Atlantic infralittoral biogenic habitat
-
MB221 : Worm reefs in the Atlantic infralittoral zone
-
MB222 : Bivalve reefs in the Atlantic infralittoral zone
