The alluvial forest is distinctive in its hornbeam formation at slightly higher locations . The alluvial forest has a high proportion of dead wood . The Crassensee, an oxbow lake of the Elbe, is embedded in the alluvial forest . The Crassensee is often surrounded by reeds made of reeds , broad and narrow-leaved cattails , plumes of water and calamus . The bank sedge and crab claw societies settle in silting zones, especially in the west of the lake . On the north bank of the Crassensee, the former sliding slope of the oxbow lake, there is an alluvial meadow with different degrees of use.
