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)
-
MH : Pelagic water column
-
MH1 : Neuston
-
MH2 : Completely mixed water column with reduced salinity
-
MH3 : Completely mixed water column with full salinity
-
MH4 : Partially mixed water column with reduced salinity and medium or long residence time
-
MH5 : Unstratified water column with reduced salinity
-
MH6 : Vertically stratified water column with reduced salinity
-
MH7 : Fronts in reduced salinity water column
-
MH8 : Unstratified water column with full salinity
-
MH9 : Vertically stratified water column with full salinity
-
MHA : Fronts in full salinity water column
