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 UK's Marine Habitat Classification has been integrated with EUNIS.
MarLIN's habitat information is listed below by EUNIS code.
