Riebener See

The lake is a nature reserve; Bird Watching web

The Riebener Sea ( Slavonic ryba = fish ) is a eutrophic Klarwasserflachsee and thus for Brandenburg rather rare type of water. It is located in the Nuthe Nieplitz in the eponymous village instincts, a district of Beelitz district Potsdam- agent Mark. The natural sheltered waters with the shape of a snail extends from west to east for a distance of half a mile and has a maximum width of around 600 meters.

Nature Spatial Integration

The silted, Reed -rich shores of the lake are largely Riebener marshy and inaccessible. Swimming and fishing are prohibited. The entire river is a valuable habitat and bird refuge and breeding area. He belongs to a chain of lakes in the Nuthe Nieplitz lowlands, which was formed at the end of the Weichsel glaciation as Zwischenurstromtal the defrosting glaciers about 20,000 years ago.

The lake is located on the southeastern edge of the Neuseegebietes at Stangenhagen in the range of Nieplitz, pepper flow and an extensive grave system in 1991 and its demolition in 2000/ 01 renatured since the shutdown of the pumping stations to the former fen. With the elevation of the water table, the Verwallungen could be lifted on pepper yield. Since 2004, the natural flow, the long -filled Vohskutengraben from Riebener lake is restored to pepper ditch. For fish and other water walkers so that is the way through the pepper and the flow Nieplitz consistently passable until Blankensee. A tributary has not the groundwater -fed lake.

Flora and Fauna

Since the abandonment of intensive fishing and duck mast on the shore around 1992, the lake has again become the paradise for birds and recovers the contaminated water. The protection and preservation of its ecological function to be guaranteed since the acquisition by the landscaping conveyor Club Nuthe Nieplitz lowland eV in 2001.

Flora

The lake is surrounded by a dense reed beds and alder -lined swamps in the silted shore zone, which hardly allowed for a view of the lake before the construction of Bohlen path. The water of the lake Riebener is much clearer than that of the adjacent lake and Blank Grössinsees. The depth of visibility extends to the ground and the soil covered an almost closed vegetation.

Breeding area for birds and pile web

The quiet and secluded lake is a preferred resting, sleeping, and breeding place for birds. In addition, several thousand of the 60,000 Nordic geese of the area overwinter in the lake. In the old trees a peninsula, a cormorant colony has set up. Warbler, Common Pochard, Great Crested Grebe, Little Grebe, cranes and swans are native to the lake. The guest performance of a bittern ( Botaurus stellaris ) in recent years gives hope conservationists that even this sensitive and strictly protected bird will one day belong to the population. Throughout Europe, particularly in Germany protected and endangered marsh harrier (Circus aeruginosus) has been one of the lake-dwellers.

Since 2006, allows a pile web with observation deck offers a view over the entire lake. The land at the former Seeabfluss pushes around 20 meters in through the reeds in the lake and is lined on both sides to protect the wildlife with wood. The panel allows many perspectives. It was implemented in the context of land consolidation in instincts with the aim to bring interests of nature conservation with the needs of birders and tourism in harmony.

Fish and amphibian conservation

The lake is heavily exploited until 1992, now only occasionally traveled for emptying the eel traps with a barge. Among the residents are particularly carp fish such as roach, lead or silver bream. The lake, with its marshy riparian zones and adjacent meadows a preferred area of frogs, toads and newts. Among the seven identified amphibian species include the endangered natterjack toad. The marsh frog is most frequent.

To protect their migrations since the steady increase in road traffic 73 L were established between instincts and Zauchwitz toads fences along the highway. Because studies had shown that already led a traffic volume of 20 vehicles / hour in a loss of 20 % of the population and that from 60 vehicles / hour, the creep and Hüpftiere barely had a chance to cross the street without prejudice. 1993 were counted in the collecting buckets of protective fences around 2,000 amphibians. In February / March 1998, there were, not least thanks to the protective measures already 10,000. With these data, an amphibious control system could be enforced in the expansion of the road in 1998 as a compensatory measure for the natural procedure, which consists of five toads tunnels at a distance of 50 meters. Subsequent studies have shown that the system has been proven. The amphibian richness helps that the heraldic animal of the Nuthe Nieplitz, the white stork, is particularly widespread on Riebener lake.

Colonization of the lake

Although the name of the lake derives from the Slavic ryba = fish, he was settled, however, only detectable to 1335, some 300 years after the Slav time. At this time the lake was enough to zoom in even to the village with the same instincts, which is about three hundred meters away today. The village life was long ruled by the lake. To obtain the surrounding marshland of Vohskutengraben is already filled early and congestion have been built with a weir for water level regulation elsewhere.
