Hidden amongst the urban sprawl of Cologne lies a tranquil oasis. It is the NSG Fürstenbergmaar a nature reserve of unexpected beauty. This seemingly ordinary lake holds a fascinating history. It wasn’t always a haven for wildlife.
The NSG Fürstenbergmaar wasn’t a natural creation. Instead it’s a testament to human industry and subsequent environmental restoration. For decades this area was the site of the Graf Fürstenberg brown coal mine. The mine operated from 1901 extracting coal until 1950 when it was incorporated into the larger Frechen open-pit mine. The Fürstenberg family were the original landowners. Their name is forever etched into the landscape. Their legacy lives on in the lake’s name.
In 1982 after the mine’s closure a decision was made. The vast pit left behind wasn’t filled completely. Instead it was allowed to fill with groundwater. This created the lake. The surrounding area was then carefully replanted. Today a diverse ecosystem thrives.
The NSG Fürstenbergmaar isn’t just a pretty face. It’s a vital component of a larger ecological network. A man-made watercourse the Fürstenberggraben links the maar to the Boisdorfer See several kilometers away. This connection contributes to a significant biotope. It supports the Kerpener Bruch and other Kerpen nature reserves. The lake’s waters flow into the Erft river.
This sanctuary provides a unique habitat. Rare species such as the crested newt and common midwife toad find refuge here. Various bird species inhabit the area. Amphibians like the alpine newt thrive alongside unique dragonfly species. The banded demoiselle and the blue-tailed skimmer are rare sightings.
But accessing this hidden gem comes with certain limitations. Fishing swimming diving and other water sports are prohibited. Access for pedestrians and vehicles is restricted. The area is intended to remain largely undisturbed allowing its inhabitants to flourish undisturbed. The NSG Fürstenbergmaar is a quiet reminder. It highlights the potential for environmental rehabilitation even in areas marked by significant industrial activity. It’s a testament to nature’s resilience and the thoughtful choices we make as stewards of our environment. This quiet lake in Cologne tells a story of coal mines and ecological restoration. It’s a story worth listening to.
