Wasserfledermaus
The deciduous forest north of the lake and the shallow reeds there is an important biotope for bats, as the area produces a plenitude of insects while offering favourable milieux for hibernation. Inventories during the 1990s have documented a presence of northern bat, parti-coloured bat, Daubenton's bat, noctule, soprano pipistrelle, brown long-eared bat, and whiskered bat.
