Hallerey, Protected natural area in western Dortmund, Germany
The Hallerey nature reserve spans 72 hectares, featuring a large 33-hectare lake formed by ground subsidence from former mining activities.
The area received its protected status in 1977 and underwent expansion in 1989 through regulatory provisions to preserve its ecological significance.
The reserve represents the transformation of industrial mining grounds into a natural sanctuary, demonstrating the evolution of the Ruhr region.
Visitors can access the reserve through the Höfkerstraße parking area, located near Revierpark Wischlingen at Höfkerstraße 12 in Dortmund.
The reserve harbors 260 bird species, 174 butterfly species, and 320 vascular plant species, making it a center for biodiversity in North Rhine-Westphalia.
