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
-
MH61 : Arctic vertically stratified water column with reduced salinity
-
MH611 : Arctic water column with ephemeral thermal stratification and reduced salinity
-
MH612 : Arctic water column with seasonal thermal stratification and reduced salinity
-
MH613 : Arctic water column with permanent thermal stratification and reduced salinity
-
MH614 : Arctic water column with ephemeral halocline and reduced salinity
-
MH615 : Arctic water column with seasonal halocline and reduced salinity
-
MH616 : Arctic water column with permanent halocline and reduced salinity
-
MH617 : Arctic water column with ephemeral oxygen stratification and reduced salinity
-
MH618 : Arctic water column with seasonal oxygen stratification and reduced salinity
-
