A mosaic wetland, meadow, and woodland reserve within the Spreewald Biosphere Reserve, near Lübben in Brandenburg.
Wiesenau Nature Reserve
Wiesenau is a protected nature reserve of around 135 hectares in the state of Brandenburg, Germany, situated on the territory of the town of Lübben in the district of Dahme-Spreewald. The reserve forms part of the larger Spreewald Biosphere Reserve, a region recognized for its exceptional network of wetlands, floodplain meadows, and floodplain forests shaped by the Spree River.
The protected area is characterized by a diverse mosaic of habitats that includes former park landscapes left open to natural development, ponds, oxbow arms, sedimentation zones, wet meadows, dry grasslands, and various woodland types. This habitat diversity within a relatively compact area is the defining conservation feature of Wiesenau and the basis for its long-term protection.
Officially placed under protection on 1 October 1990, shortly after German reunification, Wiesenau represents a typical Brandenburg lowland reserve: small in size, ecologically rich, and integrated into a broader landscape of floodplain and forest ecosystems that together sustain the regional biodiversity of the Spreewald.
