Düne am Ulvenberg von Darmstadt-Eberstadt, Protected dune area in Darmstadt-Eberstadt, Germany

The Düne am Ulvenberg von Darmstadt-Eberstadt is an 8.89-hectare nature reserve on the western edge of Eberstadt. It is an inland sand dune formed at the end of the Weichsel glaciation by windblown Pleistocene sand. The dune is divided into pine mixed forest, needlegrass steppe grassland, open silvergrass dry grassland and xerothermic needlegrass dry grassland.

The inland dune formed at the end of the Weichsel glaciation in a cold tundra climate, when wind-blown sand from Pleistocene deposits piled up. Parts of the dune were protected as a natural monument from 1938 under the name "Düne auf dem Escholl"; it became a nature reserve in 1991 and an FFH area in 2001. During the Second World War a flak position stood on the dune.

The name Ulvenberg probably derives from the old personal name Ulfo, associated with the wolf. The dune is also known as Escholldüne, Düne auf dem Escholl and Eselskopp. Since 1938 parts of it were protected as a natural monument, and since 1991 the whole area has been a nature reserve.

The reserve covers about 8.89 hectares on the western edge of the Eberstadt district. Parts of the dune have been protected since 1938, first as a natural monument called "Düne auf dem Escholl", and as a nature reserve since 1991; it also became an FFH area in 2001. Visitors should stay on the existing paths to keep the dry grassland and pine stands from being trampled.

This dune is part of a 130-kilometer-long chain of inland dunes stretching from Rastatt to Mainz across the Upper Rhine Plain. This rare natural formation shows how ice age winds shaped the landscape across a vast region.
