註釋The European Red List is a review of the conservation status of c. 6,000 European species (mammals, reptiles, amphibians, freshwater fishes, butterflies, dragonflies, and selected groups of beetles, molluscs, and vascular plants) according to IUCN regional Red Listing guidelines. It identifies those species that are threatened with extinction at the regional level - in order that appropriate conservation action can be taken to improve their status. This publication summarises results for Europe's 137 native (sub) species of damselflies and dragonflies. Approximately one out of seven are threatened with extinction at the European level. One of the most important threats is the desiccation of their habitat due to the increasingly hot and dry summers combined with the intensified water extraction for drinking and irrigation.
