Geology

The nun springs from the Wanzkaer lake in the area of ​​Hauptendmoräne the Pomeranian stage of the Vistula glaciation. 15,000 years ago, at the time of the melting of the inland ice, the glacier melt water to be accumulated in the basin of today Wanzkaer lake. The pent-up water broke through the west in the lowest point of the moraine and flowed out from the Tollensebecken. Because of the steep slope of the New River was formed by headward erosion of the deeply cut into the landscape riverbed.

The slopes in this valley are lined with natural forests of red and hornbeam, oak, ash and other sclerophyllous trees. On the embankments and on gravel islands falter alder companies. The lower reaches of the nun has lower slope. The banks are also accompanied by patches of forest, but partly also with natural stocking of hybrid poplar monocultures. In the area in front of the mouth of the nun in the Tollensee a auwald similar alder-ash forest dominated ( Pruno - Fraxinetum ).

The nun is the water volume of 0.57 m³ / s, the main tributary of the Tollense. The valley in the upper reaches of the nun is designated as a nature reserve Nonnenbachtal. The underflow is part of the nature reserve Nonnenhof. The entire creek is part of the conservation area Tollensetal, is the Birds and Habitats Directive area.
