Wreechener See Nature Reserve
The nature reserve Wreechener Lake is a 72 acre nature reserve in Mecklenburg- Vorpommern two kilometers south of Putbus. The protected status was made on 12 September 1990 as part of the establishment of the Southeast Rügen Biosphere Reserve. The aim of the designation is to obtain a lagoon -like bay of the Greifswald Bodden as one of the last regional peace zones for resting waterfowl. The Wreechener lake is further characterized by sedimentation companies and is the breeding area of rare bird species. Adjacent wetlands are used extensively.
Nearby Cities are Wreechen immediately east and Krakvitz and Neukamp. There is a connection to the Bay of Greifswald.
The field condition is considered to be satisfactory, since the water status is affected by agricultural nutrient inputs. In 1997 there were in the water of the lake to polytrophic massive fish kills due to oxygen deficiency. The almost completely disappeared Makrophytenflora has settled in recent years in some areas again. In Reserve reeds are still harvested for pipe advertisement.
In the north of the nature reserve is a refuge that provides an overview. The road from Neukamp after Wreechen leads directly along the eastern border of the protected area.
Under EU law, the surfaces are part of the FFH area and bird sanctuary.
History
The Wreecher lake was formed from a Toteisblock during the last ice age. Due to the rise in sea level of the Littorina transgression flooded the land and got connection to the bay. Coast compensation processes led to the formation of sand hooks which abtrennten the lake from Bodden more and more. The lake silted up and it formed a grove and reed belt. In the West, the flow-through and lowmoors emerged.
Two large stone graves south of the protected area point to a human settlement since the Neolithic period. Not far south of Neukamp landed Prussian troops in 1678 and began the invasion of Ruegen.

Originally came in the seas from bottom lawn of comb - pondweed, hornwort, brackish water - crowfoot and Chara spp. After this disappeared in recent decades by nutrient inputs and subsequent deterioration of water quality, these species could be detected in the past few years new colonization.
