Have you ever felt the cool embrace of a lake formed from the heart of a coal mine? Welcome to the NSG Heide Bergsee und Schluchtsee in Ville-Seenkette. This nature reserve near Cologne holds a secret. It’s a story etched in the very landscape a testament to nature’s resilience. The Heide Bergsee and the Schluchtsee weren’t always here. They are the legacy of brown coal mining a process that reshaped the land.
The NSG Heide Bergsee und Schluchtsee is a haven of biodiversity. The Schluchtsee a slender lake. It’s a mere 55 meters wide. Yet it stretches for 620 meters. A hidden gem nestled next to its larger neighbor the Heider Bergsee. Together they form a unique ecosystem.
Before the lakes existed this area was a bustling brown coal mine. This was part of the larger Rhenish lignite mining district. Mining continued until 1964. Then the transformation began. The landscape was carefully restored. The resulting lakes became havens for a surprising array of wildlife.
The Schluchtsee is exceptionally interesting. It’s a surprisingly deep lake. While its average depth is only 0.90 meters its maximum depth reaches 7.5 meters. This depth creates a unique habitat for various aquatic plants and animals. These include the endangered Nitellopsis obtusa. This species was once thought extinct in North Rhine-Westphalia. Its presence here is a testament to successful ecological restoration.
The Heider Bergsee a much larger lake. It’s 35.4 hectares a vibrant and varied ecosystem. It supports a diversity of bird life. Birds like the great crested grebe the osprey and various species of wild geese find refuge here. The lakes also support other wildlife. You can find amphibians like the green toad. Many insects thrive here including the scarce chaser dragonfly.
The NSG Heide Bergsee und Schluchtsee isn’t just a pretty place. It’s also significant for research. Scientists study the area’s unique ecosystem. They learn about the successful reclamation of former mine sites. They conduct research on rare and endangered species. It is a living laboratory. A model for environmental restoration.
