Dollerup Hills
Midtjylland
Dollerup Hills, located southwest of Viborg in central Jutland, Denmark, is part of a Natura 2000 protected area encompassing 1,524 hectares. This region is characterized by its striking moraine hills rising over 80 meters above sea level and the adjacent Hald Lake, which reaches depths of up to 31 meters. The area hosts a rich biodiversity including unique aquatic fauna and rare forest species such as the lung lichen (Lobaria pulmonaria) and the moss Antitrichia curtipendula. Historically, Hald Lake was one of Denmark's cleanest lakes until the mid-20th century when pollution from fish farms and wastewater caused ecological decline. Restoration efforts since the 1980s, including oxygenation of the lake's bottom waters and reduction of nutrient inflow, have improved water clarity and biodiversity. The forests around the lake are ecologically valuable, harboring rare old-growth forest species and the endangered bark fungus known as the whitish crust fungus, found only in this area in Denmark. The area also includes varied habitats such as meadows, oak thickets, heath hills, and ancient burial mounds, all protected within a nature reserve expanded since its first designation in 1909.

Histoire
The Dollerup Hills area was first legally protected in 1909, making it one of Denmark's earliest nature reserves.
Over the decades, the protected zone has been expanded multiple times to include surrounding forests, lakes, and moraine landscapes.
In the 1950s, Hald Lake suffered ecological degradation due to pollution from fish farms and wastewater.
Restoration initiatives began in the 1980s, notably oxygenating the lake's bottom waters and reducing nutrient inflows, which revitalized the ecosystem.
In 2011, the area became part of the Natura 2000 network under the European Union's nature protection framework, ensuring continued conservation efforts coordinated with regional water management plans.
