The nature reserve Cossensee is a 128 hectare nature reserve in Mecklenburg-Western Pomerania, three kilometers northwest of Krakow am See , immediately east of Greater Ticino . It was placed under protection on July 7, 1993. The protected area includes the Cossensee with the adjacent silting belt and moor forests.

The current state of the area is assessed as good. The occasional - unauthorized - fishing use has a disruptive effect on some bank areas. With the exception of a bathing area on the lake, it is not possible to enter the protected area.

history

The Cossensee goes back to a form of dead ice that was created between two ice edge layers during the last ice age. The block of dead ice was covered with sand so that today's spring lake is surrounded by nutrient-poor sand sands and is fed by calcareous groundwater. The lake reaches a depth of four meters. A burial mound from the Bronze Age to the north documents an early settlement. The lake silted up in the course of time, whereby this process was accelerated by the construction of drainage ditches to dry out adjacent moors and a corresponding lowering of the lake level. Lake terraces are evidence of a formerly higher water level. Adjacent areas in the west and south are used as meadows and pastures. Pine forests adjoin the lake to the north and east, with oaks up to 300 years old. A dam built on the north bank in 1989 was supposed to be used for the extraction of sea chalk, but this was not realized.

Flora and fauna

The nutrient-poor lake still has extensive ground lawns with candelabrum algae and mermaid . Base mats with fever moss in greater water depths are worth highlighting . The lake terraces are covered with reed beds. Typical species are swamp fern , reed , peat moss , common and medium water hose and hedgehog cob . A quarry forest can be found on the west and north banks. Adjacent wet meadows are home to rare species such as cabbage thistle and broad-leaved orchid .

Breeding birds in the area are ponds and reed warbler , pipe and grasshopper warbler , reed bunting , gray goose , bitterns , cranes , marsh harriers and water rails . Otters and pine marten live in the reserve.
