EUNIS Habitat classification list (2022)
The European Nature Information System (EUNIS) is a reference information system, designed to bring together information resources on species, habitats, and sites across Europe. The EUNIS database provides information to support conservation across Europe and, in particular, Natura 2000 and the work of the European Environment Agency (EEA). The EUNIS Habitat Classification system was developed for all habitats across the terrestrial, freshwater and marine environments in Europe, to provide a unified system for the description of European habitats. The Marine Habitat Classification for Britain and Ireland (MHCBI, JNCC, 2022) is integrated with EUNIS. Please note that the structure (hierarchy) used by EUNIS and MHCBI differ so not all biotopes share a one-to-one relationship, and not all MHCBI biotopes list of our website access via the EUNIS list.
