Data
The review of the marine component of the EUNIS habitat classification was initiated in 2014. Marine benthic habitats, marine pelagic and marine ice associated habitats are separated into three distinct groups, each with a separate classification structure. The first major division in the benthic marine part of the EUNIS classification is based on major biological zones (related to depth) and substrate type. Level 3 reflects the main biogeographical regions of Europe’s seas based on their distinct combinations of salinity and temperature regimes (Arctic, Baltic, Atlantic, Mediterranean and Black Sea). From 16 June 2021 the classification was complemented with crosswalks to Habitats Directive Annex I and to European Red List of Habitats. Crosswalks to marine EUNIS habitats of version 2012 need to be revisited.

An extensive review of the EUNIS terrestrial habitat classification was initiated in 2012 based on European vegetation plot data. The first groups of the classification to be revised were forest and other wooded land and heathland, scrub and tundra. The review concerns codes, scientific names and descriptions. A new element of the revised classification is that indicator species are identified for level 3 habitat types. The revision of the groups were concluded after a consultation with EIONET and vegetation experts. The review is on-going and more groups will become available as will also crosswalks from revised groups to Habitats Directive Annex I, to European Red List of Habitats and to the EuroVeg CheckList 2016. Links to the detailed methodology are in the Documents tab.

The 2007 habitat types were not changed in the 2012 description revision which mostly replaced Palaearctic or UK Marine habitat classification codes used in habitat descriptions at levels 5 and below with their EUNIS classification equivalents. In 2019 the classification was further amended to include two new habitats of the revised Resolution 4 of Bern Convention as adopted at the 38th Standing Committee meeting, November 2018. The two habitats are G3.4G Pinus sylvestris forest on chalk in the steppe zone and X36 Depressions (pody) of the Steppe zone.

Reports from the projects leading to the revision of EUNIS habitat classification, including a detailed methodology, are available at https://forum.eionet.europa.eu/nrc-biodiversity/library/eunis_classification/reports. Below are documents and crosswalks for the 2019 marine classification and the 2007 (revised descriptions 2012) version of the classification.

Cross-walks between the EUNIS habitat classification and other hierarchies (e.g. Habitats Directive Annex I habitat types or Corine land cover classes) are available from the Documents tab.
The EUNIS habitat groups that are revised will be published in parallel to the EUNIS habitat classification 2007. A maximum of 20 indicator species for each of the revised habitats is included in the Excel file. The full lists of indicator species are available from the background reports.
