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.-

-
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
-
