The European Union has nine terrestrial biogeographical regions, each with its own characteristic blend of vegetation, climate and geology. Working at the biogeographical level makes it easier to conserve species and habitat types under similar natural conditions across a suite of countries, irrespective of political and administrative boundaries. The same map is used for the Council of Europe’s Emerald network.

The methodology used to create the map is described in "The Biogeographical Regions Map of Europe - Basic principles of its creation and overview of its development".
The biogeographical map covering the EU 27 terrestrial biogeographical regions can be downloaded from the EEA dataservice here. The spatial boundaries of the biogeographical regions can be downloaded here
Since 2000 EU Member States are actively working on establishing a marine component of the Natura 2000 network. For this purpose, five marine regions have been agreed which serve the same purpose as terrestrial bio-geographical regions.
