The interest group contains the fact sheets of the European Red List of Habitats. It was a project carried out between 2013-2016 on behalf of the European Commission. An assessment was produced of the status of all natural and semi-natural habitat types at European and EU28-level. In addition to this assessment, other important information collected for each habitat type is documented in the fact sheets. A total of 490 habitat types were assessed. For both terrestrial and marine habitats the Red List typology was based on the EUNIS habitats classification at level 3 for the terrestrial and level 4 for the marine ones.
