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
-
MA61 : Arctic littoral mud
-
MA62 : Atlantic littoral mud
-
MA63 : Baltic hydrolittoral mud
-
MA64 : Black Sea littoral mud
-
MA65 : Mediterranean littoral mud
-
MA651 : Assemblages of Mediterranean littoral muddy sands and muds in lagoons and estuaries biocenosis
