Annex I habitats and Annex II species occurring in the UK

This table is a complete list of Habitats Directive Annex I habitat types presently known to occur within the UK, and Annex II species that are known to occur (or to have occurred in recent times) as native populations within UK territory (excluding Gibraltar). Further details are given in the background to selection (Section 1.2).

For each respective habitat or species the EU code is 'clickable' and will take you to the specific habitats or species account.
