The EUNIS habitat classification is a comprehensive pan-European system to facilitate the harmonised description and collection of data across Europe through the use of criteria for habitat identification. The classification is hierarchical and covers all types of habitats from natural to artificial, from terrestrial to freshwater and marine.

European data

EUNIS habitat classification review 2017

An extensive review of the EUNIS 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.

EUNIS habitat classification 2007 - updated 2019 as regards two habitats

The full list of EUNIS habitats (2007): codes, scientific names and revised descriptions. The EUNIS habitat descriptions were revised in 2012. The revisions are mostly replacing Palaearctic or UK Marine habitat classification codes used in habitat descriptions at levels 5 and below with their EUNIS classification equivalents. In 2019 the table of 2007 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.


Documents about the EUNIS habitat classification

Reports from the projects leading to the revision of EUNIS habitat classification since 2017, including a detailed methodology, are available at Below are documents and crosswalks for the 2007 version of the classification.


Additional information

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.
