NSG Fürstenbergmaar
NSG Fürstenbergmaar is a shallow, marshy lake between Kerpen and Frechen in Germany’s Ville landscape. Forest, scrub and nutrient-poor grassland surround the water within nature reserve BM 009, part of the Rheinland Nature Park. Moist habitats support water birds, amphibians and dragonflies, including the threatened natterjack toad, green toad and rare demoiselles.
The lake formed in 1982 after the Frechen open-cast lignite mine closed. A remaining depression filled with groundwater when the mine’s water management ended, creating a reclaimed wetland around 71,000 square metres in area. Its water connects through the artificial Fürstenberggraben to the Erft system and Boisdorfer See, about four kilometres northwest, joining a wider network of protected habitats.
A higher circular trail measures about 1,440 metres and lets you observe the reserve from a distance. Access to the shore remains restricted, while fishing, swimming, diving and other water sports are prohibited. Its basin reaches six metres at the deepest point, a quiet reminder that industrial ground can become valuable habitat.
