Relationships with other schemes
These are the instructions on how to enter information under the ‘Relationships with other schemes’ topic
in the Habitat Definition. All instructions are written in red. Please write your own answers in black and
remove the links and guiding texts from the Habitats Definitions. Remember to also copy this section to the
Habitats Fact Sheet, under the Classification topic on the first page.
Annex 1 relationships
The relationship between HUB biotopes and Annex 1 habitats has not yet been mapped
by HELCOM.
No photograph currently available for this habitat.
No corresponding habitat type found.
The biotope does not correspond directly to any EUNIS (2004) level 4 habitats due to
structural differences the classification systems. The closest correspondence in EUNIS is
found in the level 4 habitat ‘Deep circalittoral mud’ (A5.37).
MAES relationships
Marine – Marine inlets and transitional waters
Marine – Coastal
MSFD relationships
Please choose the relevant category or categories for your habitat from the attached crosswalk between
EUSeaMap and MSFD predominant habitat types (Annex 1). Only the highlighted habitats are relevant for
the European Red List of Habitats project.
EUSeaMap relationships
Please choose the relevant category or categories for your habitat from the attached crosswalk between
EUSeaMap and MSFD predominant habitat types (Annex 1). Only the highlighted habitats are relevant for
the European Red List of Habitats project.
IUCN ecosystem relationships
Please choose the relevant category or categories for your habitat from the attached IUCN Habitats
Classification Scheme (Annex 2).
