In the area of the old mouth of the River Salza, the River Enns was widened on both banks along an approximately 200 m stretch and structured essentially naturally. In the area subject to measures, removal of the stone reinforcements and lowering of the banks has amplified the exposure of both the old and new alluvial forest areas to the dynamics of flooding of the River Enns, allowing features typical of a river and alluvial forest landscape to develop once more.
This containment area connected to the River Enns offers habitat and shelter during flooding to juvenile fish and fish species that avoid strong currents. Numerous ponds structured with deadwood were created for amphibians.
