Donauried
The Donauried is a river landscape around the Danube in western Bavaria between Neu-Ulm and Donauwörth. Water meadow woods dominate the scene from Ulm to Lauingen. In addition, the man-made reservoirs near Faimingen, the Swabian Donaumoos between Ulm and Gundelfingen as well as the Gundelfingen park landscape in this wetland region of the Danube are of international importance under to the Ramsar Convention, the international treaty on wetlands. Birds, amphibians, dragonflies, damselflies, grasshoppers, crickets and butterflies have their habitats in the fens. Several species of plant native to the Donauried are classified as endangered on the IUCN Red List and reserves like the Apfelwörth or Eastern Donauried Bird Reserve have been established to protect the variety of species. A particular success in recent years has been the recolonisation by the white stork (Offingen, Gundelfingen, Lauingen, Höchstädt).
