With a size of 1.300 ha, Lake Dümmer is the second largest lake in northeastern Germany. A eutrophic shallow lake, it is surrounded by an extensive margin that is bordered by large-scale lowland fens formed by the aggradation of the originally distinctly larger lake. Drainage of the lowland started as early as the Middle Ages, intensifying in 1953 when dykes were built and intensive agriculture started. Since 1987, the purchase of extensive areas has allowed for the restoration of the original wetlands with high water levels, periodic flooding, and extensive agriculture.
Today, the Dümmer Lowland is one of the most important regions for nature conservation in Lower Saxony and beyond. Registered as a wetland of international significance, it serves as a resting and wintering ground for numerous waterfowl. The lake and adjacent wet meadows are nationally important breeding grounds for bird species from the siltation areas and wet meadows. The area is a registered EU bird sanctuary and is - in parts - protected through the Habitats Directive. The implementation of large-scale conservation measures was partially enabled by two EU-funded LIFE-projects .
The silted-up areas are particularly densely populated by the Moor Frog - the Pool Frog has been spotted as well. After several decades of absence, a sighting of the European Tree Frog was recorded in 2009. Next to the permanent settlement of this species in the area, this project also aims at the northward dispersion of the Moor Frog and Pool Frog.
The project area offers numerous interesting and fun opportunities for observing nature on-site, including observation towers and adventure trails.
