The Linowsee-Dutzendsee nature reserve is a 60-  hectare nature reserve and FFH area in the Natura 2000 network in the Brandenburg districts of Oder-Spree and Dahme-Spreewald .

It is located in the Dahme-Heideseen nature park southwest of the Groß Schauener chain of lakes . The core of the protected area is the 8.5 hectare Linowsee and the silting moor of the former Dutzendsee. The protection purpose is in particular the preservation of wild plant communities such as humid high herbaceous meadows , poor lowland hay meadows , moor forests and spawning or frog-bite communities of nutrient-rich still waters as well as endangered species of the water silting areas, the reed beds and alder swamps .

Location, natural space and geomorphology

The nature reserve begins at Linowsee south-east of the Rundlingsdorf Streganz , a district of the Heidesee community . In a largely muddy valley, it stretches around 4.7 kilometers to the southeast in the districts of Storkow / villages Selchow and Schwerin . The north-eastern corner of the area extends up to around 300 meters to the Schweriner See , part of the Groß Schauener lake chain , which is also protected and part of Sielmann's natural landscape, the Groß Schauener Lakes . On the northeast corner leading county road K 6746 by participating in the fishery Köllnitz, a living space of Storkower hamlet of Great look , from the Federal Highway 246 branches off and leads via Selchow to Schwerin and ends there.

The site is located south of the Berlin glacial valley, through which the Spree flows, and west of the Storkower Platte in the East Brandenburg heath and lake area , which is listed as No. 82 in the main natural areas of Germany . The numerous lakes in the area are a relic of the Brandenburg stage (24,000 to 22,000) of the Vistula Ice Age . Located at a height of around 40 meters, the lowland of the protected area is bordered in the south by a wooded ridge that rises to 84 meters close to the Linowsee in the Streitberg (formerly Eichberg). The geologist Olaf Juschus assigns the lowland to the smaller Vistula glacial drainage channels and describes it as the Streganzer Talung . Then the valley separates part of the Groß Eichholzer Platte with the Streitberg in the south from the Klein Eichholzer Platte in the north.

Linowsee and silting moor Dutzendsee

The Linowsee drains via a river to the northwest into the Streganzer Gutssee , from which a ditch leads east into the Schweriner See. The drainage ditches of the moored Dutzendsee, on the other hand, lead the water in the opposite direction directly to the east into Lake Schwerin.

Linowsee

The eutrophic lake, only around 1.2 meters deep, is roughly round in shape and covers an area of ​​8.5 hectares. The lake level is 37.6  m above sea level. NHN . The name comes from the alpb. Basic form * Linov- =, to * lin = Schlei back, means Schleisee.

Dozen Sea

Area of ​​the former Dutzendsee

The body of water was first written in 1745 in the general designation and description of all in the Chur Mark and incorporated lands and / or bodies of water that touch the same, as rivers, streams, leches, brooks, canals, ditches, lakes, puddles, ponds [...] as Tutzna See recorded. In 1772 there is an entry as Tutzna Lake . The Prussian first recording designated the lake in 1846 as Dutzen See , which Karl Eckstein followed in 1908 in his volumes on the fishing conditions in the province of Brandenburg in the spelling Dutzen-See .

The name is derived from the Old Polish / Old Sorbian basic form * Tučn- to the adjective * tučn- = fat, nutritious , from * tuk = fat, tallow, lard . The name refers to nutritious = fish-rich waters and occurs several times in Brandenburg, for example in the Teutzensee or the Ruppiner waters in the Tietzensee . The later form Dutzendsee was adjusted to the numeral dozen by folk etymology .

The Dutzendsee, which was completely silted up in the 21st century, is still shown as a body of water in a measuring table sheet of the Prussian new recording from 1903. The lake was surrounded by wet meadows and open areas as well as - on the northeastern shore of the lake - a residential area Werder , which was populated by fishermen. In addition to fish, they also took crab claws and fed them to pigs. Aerial photographs from 1950 and 2010 show the fundamental changes around the lake: The wet meadows have largely disappeared when the water was drained from the lake through a wide ditch. The water maintenance association has installed a bottom slide, but it is set so low that the wet meadows do not receive enough water for most of the year. Due to the low water level, the peat soil receded, sweet grasses and herbs disappeared in favor of robust sedge and rushes. In place of the former belt of reeds, alders thrive, bushes penetrate ever deeper into the formerly free water surface.

Roughly square in shape with two bulges in the north and south-east, it had almost the same area as the Linowsee. Its height is given as 37.4 m, while the Linowsee is still recorded at 38.2 m (currently 37.6 m).

The NSG Linowsee-Dutzendsee is part of the coherent European ecological network of special protection areas Natura 2000 . The profile of the Federal Agency for Nature Conservation (BfN) contains the following characterization for the 60 hectare FFH area under the number 3749-305:

"Smaller complex of silting shallow lakes with surrounding wet forest and grassland areas."

- Federal Agency for Nature Conservation. Profile of the FFH area Linowsee-Dutzendsee.

The ordinance on the "Linowsee-Dutzendsee" nature reserve of June 30, 1995 (the publication of the ordinance and thus its entry into force took place on October 10, 1995 in the Law and Ordinance Gazette for the State of Brandenburg ) emphasizes under § 3 protection purpose :

"Protection purpose is the preservation and development of the area
1. as a location of rare wild plant communities threatened in their existence, in particular silting societies of the Linow and Dutzendsee lakes, various alder and willow breaks, wet meadow communities and sedge meadows as well as active silting bog areas;
2. as a habitat for endangered animal species, in particular vertebrates threatened with extinction, and as a breeding and feeding area for species-rich bird fauna (e.g. ducks, railings) and insects (e.g. large butterflies) in the water silting areas, reed beds and alder quarries;
3. for ecological reasons to restore or secure water level conditions, which enable the activation of the silting bog of the Dutzendsee, to ensure the preservation of the structural diversity of the plant communities adapted to the silting processes, to restore the initial conditions for the development of meadow locations rich in flowering plants around the Dutzendsee support and guarantee. "

The nature reserve was accepted as a project area by the EuroNatur Foundation .

Flora and fauna

Habitat types and plants

Meadows and forests on the former Dutzendsee

The Federal Agency for Nature Conservation lists four plant communities as habitat types to be protected in the FFH profile :

Noteworthy are the occurrences of the large mermaid herb ( Najas marina ), which is rather rare in Brandenburg , the common water hose ( Utricularia vulgaris ), which is listed as endangered, and the equally endangered frog bite .

Animals

The profile lists the otter as a species of community interest according to Annex II of the Habitats Directive . The land carnivore from the marten family is listed as threatened with extinction in the Brandenburg Red List (status 2003) despite a slight recovery in its populations . Tench still dominate the Linowsee . Gray herons hunt on the shallow waters . In 2013 over 60  swans were counted on the Linowsee.
