Gegenwärtiger Zustand der Schweizerischen Auengebiete, dargestellt anhand des Vergleichs vegetationskundlicher Kartierungen
[Present state of Swiss alluvial floodplains characterized by vegetation mapping]
The recent development of the alluvial floodplains of Switzerland shows a drastic change of vegetation. Many typical plant species or plant communities of the alluvial zones are diminishing or disappearing. Most sites are succeeding from an active alluvial system to a "pseudo-alluvial" inactive system, even if they remain biologically very rich.
