The Werderfließ is a 400 meter long watercourse in Buckow in the Brandenburg district of Märkisch-Oderland . The river forms the outflow of the Schermützelsee , with 137 hectares the largest body of water in Märkische Schweiz in the center of the nature park of the same name around 50 kilometers east of Berlin . It flows into the Buckowsee , through which the Stobber flows. This means that its waters reach the Oder via the Stobber . On its course through the eponymous Werder between the lakes, the stream flows through a pronounced quarry forest .
Course and bridges
The Werder river begins south of the Brecht-Weigel-Haus on the eastern shore of the Schermützelsee. After a short walk to the west, it reaches the end of Bertolt-Brecht-Straße, where it crosses the connecting path to the White Lake . The trail is part of the European long-distance hiking trail E11 , the circular trail around the Schermützelsee and the terrain spa network of the Kneipp spa town of Buckow. The Werder river bridge spanning the stream is made of natural stone and is a round arch bridge with an overhead roadway. To the east of the bridge, next to the parking lot at the Brecht-Weigel-Haus, the town of Buckow has set up a hydrotherapeutic Kneipp water point .
After the bridge, the water turns to the northwest and flows through an extensive alder quarry that extends from the west bank of the 14-hectare Buckowsee on the headland (Werder) between the lakes to Bertolt-Brecht-Strasse and Werderstrasse and continues south along the Stobber . In this area, left in its natural state, the flow reaches a wooden bridge that leads the rubber path over its course. The Gummiweg is a boardwalk that was created for hiking tourists to explore the quarries and connects Werderstraße with the Luna Park on Buckowsee. Around a hundred feet east of the bridge that joins Werder flow slightly meandering in the northwestern part of the Buckowsees.
Slope and discharge volume
The slope of the 400 meter long creek from 26.5 meters above sea level. NN located water level of the Schermützelsee to Buckowsee at a height of 25.5 meters is one meter. On this gradient, the Werder river, which is around two meters wide after the stone bridge, transports an annual runoff volume of 6.0 million m³ (annual series from 1983 to 1992). The Werderfließ forwards around 3.5 million m³ (annual average from 1977 to 1984) from the Sophienfließ , which flows into the Schermützelsee in the northeast. The remaining 2.5 million m³ should therefore mainly come from the groundwater supply of the Schermützelsee, since the lake has no other noteworthy tributaries.
Geology and formation of waters
The Werderfließ is located in the Buckower Kessel, a basin-like extension of the Stobbertal. The valley is part of a glacial meltwater channel that formed in the last two phases of the Vistula Ice Age between the dead ice- filled Oderbruch and the Berlin glacial valley (today's Spreetal) and separates the Barnimplatte from the Lebuser Platte . This approximately 30 kilometers long and two to six kilometers wide Buckower Rinne (also: Löcknitz-Stobber-Rinne ) drains from the low moor and headwaters area Rotes Luch via the Stobber to the northeast to the Oder and via Stobberbach / Löcknitz to the southwest to the Spree . According to current accounts, the strains and tensions of the last glaciation and the thawing glaciers in the subsurface of the Buckower Kessel left numerous smaller incursions. The lower basins were filled with gradually rising groundwater and formed several lakes, including the Buckowsee, Schermützelsee and Griepensee . Friedrich Solger , professor of geology at Berlin's Friedrich-Wilhelms-Universität in the 1920s, described the remaining lakes in the Stobberlauf, such as the Griepensee , as the undoed remnants of a chain of lakes in the Stobbertal. The fen that flows through the Werder river is another relic of this development process. Other representations attribute the formation of the lakes in the Buckower Rinne to the thawing of blocks of dead ice. After thawing, voids were created in the blocks that had been separated and buried by the glacier ice, which filled with water after their collapse
Flora and fauna
The Werderfließ is only accessible to the public in the area of the two bridges and is largely surrounded by a species-rich alder forest, which is made accessible by a stick dam ( rubber path ) laid out with robinia posts . The quarry forest provides habitat for several dozen species of birds, 70 species of large mushrooms and over 150 species of insects, including 75 species of butterflies.
Natural alder curd
The permanently wet, but not long-term flooded, fen soils of the quarry forest ensure a medium to good supply of nutrients . Black alder trees dominate the forest and can cope with the high humidity and, thanks to their adventitious roots, also fluctuating water levels. Occasionally, bog birch trees are interspersed with the trees. In less developed shrubby undergrowth beside heavily overgrown alder stems are black currant and buckthorn represented - the altpolabische / altsorbische name čremucha for Faulbaum the Schermützelsee gave the name. In the abundantly developed ground plants, large sedge such as sour grasses and water lizards predominate. In addition, there are occasional nightshades , shield ferns and swamp irises in the area of the Werder River and Buckowsee shore . While mosses are rarely found, there are various types of large mushrooms in the wetland - the most persistent are the alder schillerporlinge , a saprobiontic or parasitic wood dweller like all schillerporlinge that attacks deciduous trees and causes white rot in the affected wood .
The break is not used for forestry . According to the information board on site, management would only be possible with complex regulation of the water balance due to the damp subsoil . Because of its high value for landscape and nature conservation , it is therefore advisable to keep water regulation as low as possible and to leave the black alder burch to its natural development.
Animals
From the family of weevils falls due to its distinctive snout ( rostrum of) Erlenrüssler (alders shrikes, Cryptorrhynchus lapathi on). The larvae of the insect pest overwinter in the bark and drill up to 10 centimeters long tunnels in the wood. The young beetles feed on the young shoots. Typical symptoms of the infestation are withered shoots, distended parts of the bark, entrance holes and wood chips. The shiny blue alder leaf beetle also uses the alder as food. The females lay clutches of 60 to 70 eggs on the underside of the leaves. The leaf beetles can eat the alder up to three times a year. The fruits of the winter black alder remain on the tree throughout the winter. In the cold season, the woody cones of the female flowers, which form three brown, flattened, solitary nut fruits per scale , serve as the most important source of food for many bird species. These include siskins and goldfinches . The area where the Werder River flows into the Buckowsee is used by some water birds such as ducks and railing birds . As part of the European Bird Protection Area (SPA) Märkische Schweiz for the conservation of wild bird species according to the EU directive , which with 17,968 hectares occupies the largest part of the 20,500 hectare nature park, the Bruch is the habitat of many other endangered bird species.
