All dragonfly species native to Europe are included, except those confined to northern Caucasus. The geographic scope is continent-wide, extending from Iceland in the west to the Urals in the east, and from Franz Josef Land in the north to the Mediterranean and the Canary Islands in the south. The Caucasian region is not included. Red List assessments were made at two regional levels: for geographical Europe, and for the 27 current Member States of the European Union.
