Buttermoor / Butterbargsmoor, nature reserve in Schleswig-Holstein, Germany

Buttermoor / Butterbargsmoor is a protected nature reserve covering about 105 hectares in the Holm and Wedel region. The moorland consists of open areas with heather vegetation, wet sections with marsh plants, and sandy dunes in the southern part where bell heather, orchids, and moor grass grow in nutrient-poor soil.

The area formed after the last ice age in a low-lying depression where peat and vegetation accumulated over millennia. It was officially designated as a protected reserve on December 14, 1992, to preserve the natural processes of this moorland after it had been partially drained and dried out.

The name Buttermoor combines "Butter" with "Moor", the German word for bog. The reserve lies in the municipalities of Holm and Wedel in the Pinneberg district of Schleswig-Holstein and is a remnant of a moor and heath landscape that was still continuous about 100 years ago between the two municipalities and Hamburg-Sülldorf. Visitors today see bell heather, purple moor grass and, on the dune edges, common heather.

The area is accessible via several walking trails that allow visitors to explore the moorland on foot and observe birds, amphibians, and other wildlife. Information signs along the paths explain the plants, animals, and history of the site, helping visitors understand why the area is protected.

The reserve preserves a remnant of the moor and heath landscape that still stretched between Holm, Wedel and Hamburg-Sülldorf around 100 years ago; the southwest edge holds inland dunes formed by wind-blown sand, next to the glacial-till basin.
