This report descibes the EUNIS habitat classification review which provides the context for a number of policy-related ecosystem and habitat assessments. It is a European reference to which other national or regional classifications can be cross referenced. The review of terrestrial EUNIS habitat classification, on the basis of georeferenced vegetation samples, aims to enhance the technical capacity for documenting, monitoring and assessing the quality of habitats at the European level. This work strengthens the knowledge base that is used for assessing progress towards the European Union (EU) and global biodiversity targets for 2020.


A new approach to define indicator species was applied to forest habitats in the frame of a contract that was finalized in 2016. The expert system for EUNIS forest habitats was refined, using updated species groups and new software functions. Based on this, refined classification of forests was prepared. An additional Annex 5 with the forest indicator species (diagnostic, constant and dominant) is made available for forest habitats.
