Whispers of forgotten waters echo through the Postfenn und Teufelsfenn. This unique nature reserve in Berlin’s Grunewald forest holds a captivating tale. Postfenn und Teufelsfenn started as glacial lakes. These lakes, remnants of the last ice age, slowly transformed into the fascinating kettle bogs you see today. The area spans a remarkable 83 hectares. Postfenn und Teufelsfenn is not just a nature reserve. It’s also part of the larger Fauna-Flora-Habitat (FFH) Grunewald, a testament to its rich biodiversity. The history of Postfenn und Teufelsfenn is a story of resilience. Groundwater depletion once threatened this delicate ecosystem. Typical bog species struggled to survive as the land dried. However, intervention brought the bog back to life. Since the mid-1980s, groundwater from a nearby well, a relic of a decommissioned waterworks, has nourished the thirsty land. Within a protected area, birch, poplar, and bird cherry trees now thrive. Remarkably, specialized bog plants like sundew also flourish, showcasing the success of the restoration efforts. Postfenn und Teufelsfenn teems with life. It is a haven for various amphibian species. Birdwatchers can delight in the presence of 35 breeding bird species. In 2008, the bog revealed another secret: the presence of the swamp grasshopper, a testament to the thriving ecosystem. The landscape here is a mosaic of different environments. The interplay of water and vegetation creates a unique sensory experience. Listen closely, and you might hear the rustling of leaves, the chirping of crickets, or the croaking of frogs. Postfenn und Teufelsfenn offers a tranquil escape from the urban bustle. It also serves as a living laboratory, where the past and present intertwine.
