The course of the Pielach, a tributary of the Danube, is in a near-natural state. Forest dominated by Alnus, Fraxinus, Acer and Salix is associated with the river. Adjacent areas are dominated by arable cultivation with two patches of Quercus woodland.
The site is important for breeding riverine species.
Pressure/threats to key biodiversity
The riverine forest is threatened with conversion to plantations and the river itself by canalization and shingle mining. The areas of the river that are important for birds are also heavily used for recreation.
