In this paper the trends of dragonfl y expansions during the last decades in Germany and Europe are summarized. It is shown, that there is a general expansion of many species to the north: Mediterranean species expanded to Central and Northern Europe, whereas some African species expanded to Southern Europe, some are even new to the continent. In general this means an increase of biodiversity, but looking at the ecological eff ects, in the medium term a decrease can be expected for mooreland and alpine species. Dragonfl ies can be regarded as a good indicator group for climatic change. Already now in some areas or regions negative eff ects on waters bodies and their dragonfl y communities can be observed and more will occur if e.g. temperature rises or precipitation decreases. Th e consequences for nature conservation strategies – such as the NATURA 2000 network – are outlined and the general need for monitoring programmes is emphasised.
