Westerberg und oberes Hackemühlener Bachtal: Mapping the Protected Landscape and Glacial Terrain

The reserve is best known for combining a glacial end moraine forested with Douglas fir and spruce alongside patches of oak, beech and oak, hornbeam woodland, with the near-natural upper course of the Hackemühlener Bach that emerges from numerous seepage springs along the slopes. It is also notable for the small-scale agricultural landscape in the southeastern part of the area, where field and bank hedgerows pattern mesophilic and wet grassland with localized orchid-rich meadows.

The landscape of the Westerberg und oberes Hackemühlener Bachtal reserve is shaped by two clearly contrasting physical elements. In the north, the Westerberg rises as a forested terminal moraine of the Saalian glaciation, with sandy, slightly elevated terrain that has historically been used for timber production. Forest plantations of Douglas fir and spruce dominate this ridge, interrupted by more natural oak-mixed forests with transitions to beech and oak, hornbeam woodland on the better sites.

In the south and east, the terrain drops into the incised valley of the Hackemühlener Bach. The stream rises within the protected area itself and flows southeastward at first, fed by seepage springs along the hillside. Its bed is sandy, with local gravel and stony sections, and the channel is largely natural within the reserve. Bank-side vegetation includes floodplain-type shrubs and tall-herb vegetation that follows the course of the water.

On the gentler lower slopes, especially in the southeast of the reserve, the landscape opens into a small-scale mosaic of grassland and farmland, dissected by field hedges and bank hedgerows. This terrain, although partly agricultural, has retained a finely structured character that contrasts strongly with the dense forest on the moraine above.

Ecologically, the reserve combines forest, stream and grassland habitats in close proximity. The moraine forest is primarily made up of productive conifer stands, but the embedded oak-mixed woodlands with transitions toward beech and oak, hornbeam forests represent a more natural habitat type and give the area a measure of stand diversity absent from purely commercial forestry.

The Hackemühlener Bach and its associated floodplain create a sharp habitat contrast within the same site. The stream itself, with its sandy and locally gravel-strewn bed, supports a near-natural aquatic and riparian community. Softwater seepage springs feed the channel from the slopes, while floodplain shrubs and tall-herb fringes line the banks, creating humid transitional habitats along the watercourse.

On the lower slopes, the reserve contains a particularly valuable grassland flora. Mesophilic meadows dominate, but smaller, ecologically significant patches include wet and orchid-rich grassland, sedge- and rush-rich flood meadow types, and mat-grass swards. The combination of hedges and varied grassland types produces a fine-scale ecological mosaic of considerable botanical interest.

The reserve was designated on 24 August 2012 to protect a combination of a glacial moraine forest and the natural upper course of the Hackemühlener Bach, including its associated seepage springs and floodplain vegetation. Its significance is reinforced by a substantial overlap with the EU Habitats Directive site "Westerberge bei Rahden," covering roughly 189 hectares of the protected area and recognizing its place in the European Natura 2000 network.

From a conservation perspective, the site's value lies in the close coexistence of forest, near-natural stream, species-rich grassland and small-scale agricultural land. The orchid-rich wet meadows, sedge- and rush-dominated flood meadows and mat-grass swards provide habitat for plants and invertebrates that depend on traditional, lightly managed grassland conditions, while the forests protect soil, water recharge and habitat continuity along the moraine.

The name Westerberg points to a long-standing local geographic identity linking the settlement of Lamstedt with its nearby forested ridge. The Hackemühlener Bach and its upper valley are equally rooted in regional naming and traditional land use, and the small-scale agricultural mosaic in the southeast of the reserve, shaped by hedgerows, reflects an older pattern of rural land management in the Cuxhaven district.

Standout features of the Westerberg und oberes Hackemühlener Bachtal reserve include the Saalian end moraine forest on the Westerberg ridge, the within-area springs and near-natural upper course of the Hackemühlener Bach, and the orchid-rich and species-rich wet grasslands on the lower southeastern slopes. The substantial overlap with the FFH site "Westerberge bei Rahden" underlines the site's national and European conservation significance within the Cuxhaven district.
