NSG Bolmke

Hidden within Dortmund’s urban heart lies the NSG Bolmke, a natural sanctuary teeming with life. Can you imagine this tranquil haven nestled so close to the bustling Westfalenstadion and Westfalenhallen? NSG Bolmke is a testament to nature’s resilience, a verdant oasis within a concrete jungle. Originally a small protected area of nine hectares established in 1991, the NSG Bolmke has grown over time. By 2005, it expanded to encompass 52 hectares of precious Emscher river valley. This area represents the last vestige of the extensive floodplain that once stretched between Hörde and Barop. The Emscher River meanders through NSG Bolmke, its once-channelized waters now freed from concrete constraints. As you stroll along its banks, observe the young willow and alder trees flourishing along the river’s edge. The NSG Bolmke is a haven for diverse flora and fauna. Imagine encountering a dipper flitting along the water’s surface. This small bird, a symbol of clean rivers, is a testament to the ongoing renaturation efforts. Beyond the riverbanks, the landscape unfolds in a mosaic of habitats. Alder, ash, willow, oak, hornbeam, maple, and red oak trees paint the forest in a tapestry of greens. Look closer and discover a vibrant understory of reeds, tall perennials, and even the invasive Himalayan balsam. NSG Bolmke holds a fascinating history. After World War I, the area witnessed a brief period of illegal coal mining, leaving its mark on the landscape. Following World War II, the Emscher valley was reforested with poplar hybrids. Today, the forest is a mix of native species and these introduced poplars. While beloved by locals as a recreational area, the NSG Bolmke faces challenges. Litter, unleashed dogs, and off-road cyclists pose a threat to the delicate ecosystem. Conservation efforts focus on preserving old-growth trees, renaturing waterways, managing visitor traffic, and addressing waste disposal. The NSG Bolmke is a reminder that nature can thrive even in the most unexpected places. It invites you to explore its hidden trails, listen to the rustling leaves, and appreciate the vibrant life that persists within Dortmund’s urban core.
