Kleine Röder Nature Reserve
Kleine Röder is a designated nature reserve (Naturschutzgebiet) in the state of Brandenburg in northeastern Germany, located on the territory of the town of Bad Liebenwerda in the Elbe-Elster district. The 385-hectare protected area lies in the Elbe-Mulde lowland and follows the course of the Kleine Röder, a left-side branch of the larger Große Röder river system. It was placed under formal protection by statutory order on 1 June 2011 and is registered with the identifier 1623.
The reserve protects a richly structured wetland landscape that combines wet meadows, fens, alluvial woodland, oak-mixed forest, willow thickets, ponds, and sections of flowing and still water. It also forms a key segment of an over-regional ecological corridor linking Saxon sites of community importance with the middle course of the Schwarze Elster in Brandenburg. In the village of Kosilenzien, part of Bad Liebenwerda, an early medieval Slavic ringwall (Slawischer Burgwall) is included within the protected area, giving the site a notable cultural-historical dimension in addition to its ecological value.
The site functions primarily as a habitat and species management area (IUCN Category IV), with conservation goals that emphasize the preservation of characteristic floodplain vegetation communities and the long-term maintenance of a wetland mosaic shaped by water, woodland, and grassland. Its biodiversity, including rare wetland plants and a variety of protected bird, amphibian, and mammal species, underlines its importance within the regional nature protection network of Elbe-Elster.
