Hidden among Berlin’s northern reaches lies K\u00f6ppchensee a tranquil lake with a surprisingly turbulent past.
K\u00f6ppchensee wasn’t always the peaceful nature reserve it is today. In the 19th century peat diggers created this lake. Their work transformed the landscape. It inadvertently laid the foundation for the rich biodiversity we see now. The lake’s shallow nutrient-rich waters and low oxygen levels are key to its unique ecosystem.
For decades after the 1920s a portion of the area became a rubbish dump. This was during the years leading up to the Berlin Wall’s construction. Then for another 40 years it lay within the Wall’s restricted zone. Imagine this desolate landscape. Now picture its remarkable rebirth. Nature reclaimed it creating a mosaic of meadowland and abandoned orchards.
This transformation provided a haven for endangered species. Wild bees and butterflies thrive here. So do birds and plants. A sandy cliff above K\u00f6ppchensee offers a rare Berlin nesting site for sand martins. The nearby Eichwerder Moorwiesen nature reserve extends the habitat along the Tegeler Fließ river. The area boasts over 40 information boards detailing the local flora and fauna.
K\u00f6ppchensee is a haven for birds. Many species nest and feed there. Over 150 solitary bee species and various meadow and hedge birds inhabit the drier areas. This includes the Northern wheatear goldcrest and various hawks and falcons.
Fish-eating birds such as herons ospreys kingfishers cormorants and storks frequently visit. Despite the presence of these predators the lake supports a large population of frogs toads and grass snakes. Reed warblers great reed warblers and bearded reedlings call the reed beds home. Grebes and moorhens are among the nesting birds.
For over a decade the NABU (Nature and Biodiversity Conservation Union) the city of Berlin and other organizations have managed K\u00f6ppchensee. They’ve organized over 100 workdays and harvested more than ten apple crops from the old orchards. These trees provide valuable habitat. Visitors are only permitted on the orchards’ surrounding meadows during the autumn harvest.
The management also focuses on preserving the steep banks. This ensures nesting sites for sand martins. Fencing around the former gravel pit protects ground bees and lizards. The dry grassland where these creatures live is regularly mown. This prevents taller shrubs from displacing the characteristic vegetation. This area remains closed to visitors to protect the delicate ecosystem.
Well-maintained paths invite visitors to enjoy K\u00f6ppchensee. These are suitable for walkers cyclists and riders. There’s even a picnic area. Fishing and swimming are prohibited. This careful management allows the diverse natural beauty to flourish. It enables visitors to experience K\u00f6ppchensee in all its unique glory.
