Aeshna viridis Eversmann in Schleswig-Holstein, Bundesrepublik Deutschland (Anisoptera: Aeshnidae)

The species is confined to bogs, ponds and lakes with Stratiotes vegetation, therefore it occurs today in Schleswig-Holstein only locally. All known records are mapped and it is stressed that, due to anthropogenic influences (fishery activities, pollution, infilling), the populations are everywhere decreasing in numbers. Measures for the conservation of a number of habitats are suggested.
