NSG Hallerey

What whispers of Dortmund’s past echo through the reeds of NSG Hallerey? This tranquil nature reserve, nestled within Dortmund, holds a secret. NSG Hallerey isn’t just a haven for rare birds and vibrant dragonflies. It’s a testament to the intertwining of nature and industry. In the early 20th century, the ground beneath us shifted. Mining activities at the nearby Zeche Dorstfeld caused the land to sink, creating the 33-hectare lake that forms the heart of NSG Hallerey. Imagine this area, once a hub of coal washing, transforming into a sanctuary. The lake, initially used for industrial purposes, now reflects the sky and shelters a thriving ecosystem. The landscape surrounding the lake is a mosaic of hedges, dense thickets, and lush wetlands. Wander along the paths, and you’ll find trees embraced by enormous climbing plants. The reserve also encompasses several rainwater retention basins and a former mining waste heap, further highlighting this unique blend of industry and nature. NSG Hallerey teems with life. Observe the vibrant Großschmetterlinge butterflies flitting through the air. Listen for the calls of amphibians like the Erdkröte (common toad), Geburtshelferkröte (midwife toad), and Kammmolch (great crested newt). Look to the skies and you might spot rare water birds, including Blesshühner (coots), Reiherenten (tufted ducks), Graureiher (grey herons), and Kormorane (cormorants). A large colony of Lachmöwen (black-headed gulls), drawn to the shallow waters, also calls NSG Hallerey home. And as dusk settles, listen for the flutter of Fledermäsue (bats), like the Wasserfledermaus (Daubenton’s bat) and the Abendsegler (Noctule bat). NSG Hallerey, designated a protected area in 1977, provides a vital green space for Dortmund residents and visitors alike. Its close proximity to Revierpark Wischlingen makes it an ideal destination for those seeking both recreation and a connection with nature. NSG Hallerey is more than just a nature reserve. It’s a living story of transformation, resilience, and the surprising harmony that can exist between industry and the natural world. This haven whispers a tale of Dortmund’s past, while offering a vibrant glimpse into its future.
