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
-
MB3 : Infralittoral coarse sediment
-
MB4 : infralittoral mixed sediment
-
MB5 : Infralittoral sand
-
MB6 : Infralittoral mud
-
MB61 : Arctic infralittoral mud
-
MB62 : Atlantic infralittoral mud
-
MB621 : Vegetated communities on Atlantic infralittoral mud
-
MB622 : Maerl beds on Atlantic infralittoral muddy sediment
-
MB623 : Vegetated communities in reduced salinity Atlantic infralittoral mud
-
MB624 : Faunal communities on full salinity Atlantic infralittoral mud
-
MB625 : Faunal communities on variable or reduced salinity Atlantic sublittoral mud
