64.1 - Germano-Baltic fluvio-glacial dunes

Classification des habitats du Paléarctique (2001)

Description

Dunes of the North Sea and Baltic plains, formed of quartzic sands originating in redeposited and reworked glacial drift and outwash. They are highly siliceous in the Netherlands, northern Belgium and northwestern Germany, progressively slightly less oligotrophic and with a more continental cortŠge in northeastern Germany, Poland and the eastern Baltic plain. The dune systems, particularly the large ones, harbour a unique ensemble of interacting communities and harbour many specialized and restricted organisms. They have considerably regressed and the remaining examples are fragile and often threatened. The presence of the various elements of the ecosystem can be indicated by simultaneous use of the codes below and of those relevant to the types of plant communities they represent.
