"Sauertal" Nature Reserve

The Sauer is a typical karst stream: in some places, the water can temporarily disappear entirely. Such disappearances of the stream—known as “swallow holes”—are just as much a part of the landscape as springs that flow only temporarily.

A variety of habitats alternate along the stream. In the valley and on the sometimes steep slopes, different biotopes have developed depending on the soil, water balance, and past land use. They provide suitable habitats for numerous plant and animal species.
