Holzurburg am Bederkesaer See, nature reserve in Lower Saxony, Germany

Holzurburg am Bederkesaer See is a large protected area featuring forests, wetlands, and open water in Lower Saxony. The landscape shows birch and pine woodlands on higher ground, wet areas with heather and cotton grass, and a lake maintained at steady water levels.

The earthwork called Holzurburg has been known by that name only since about 1900; it is a prehistoric rampart in the southern part of the woodland, not a thousand-year-old fort. The nature reserve was designated on 30 August 2007, merging the Hörner Moor and Nordostufer Bederkesaer See reserve (January 1985) and the Wehdenbruch reserve (December 1985).

The name 'Holzurburg' has been used for the prehistoric rampart in the southern part of the woodland since about 1900. Both the forest trail and the lake circuit pass by this earthwork, and information boards along the paths explain the woodland, the lake and their flora and fauna.

The area can be explored via two main walking trails: a forest path circles the woods for about four kilometers, while a lake circuit extends seven kilometers around the water. Small viewing towers provide sightlines across the water and surrounding landscape.
