The Pfungstädter Düne is an FFH area and extensive natural monument in the districts of Darmstadt-Eberstadt (independent city of Darmstadt ) and Pfungstadt ( district of Darmstadt-Dieburg ) in southern Hesse.

location

The Pfungstädter dune is located in the natural area of ​​the Hessian Rhine Plain , Pfungstadt-Griesheimer Sand. The protected area extends east of Pfungstadt along the reopened Pfungstadtbahn , on the northern edge of the Pfungstadt Galgenberg. The FFH area is mainly north of the railway line, also includes the route and a narrow strip to the south of it. The total area is 5.55 hectares. Only the 4 hectares north of the railway line count as natural monuments.

history

The "Pfungstädter Düne" belongs to the approximately 10 kilometer wide belt of drift sand dunes between Darmstadt and Rastatt , in which calcareous sands were blown into dunes at the end of the last Ice Age. The Pfungstädter dune was formerly used for sand extraction, which resulted in the embankment exposed to the south. When the railway line to Pfungstadt was built in 1850, the dune was cut and partly removed, exposing large areas of sand. It was designated as a natural monument by the city of Darmstadt by ordinance of February 9, 1954 (Natural Monument Book of the City of Darmstadt, No. 25). The dune has been protected as a Natura2000 area since 2008 (FFH area 6117-307 “Pfungstädter Düne”).

Description and protection goals

The "Pfungstädter Düne" is an elongated, predominantly mixed pine forest, which has open areas in places. The habitat types to be protected are steppe lawns (LRT 6240), open grass areas with silver grass and ostrich grass on inland dunes (LRT 2330), as well as subcontinental, base-rich sandy lawns (LRT 6120). They are the habitat for numerous highly endangered plant and animal species.

The protection and maintenance goals include, in particular, the promotion and development or resettlement of the Sand-Silberscharte . The light, species-rich pine forest is to be preserved and developed, the open spaces are to be kept open.

Flora and fauna

Ordinary easter luzei , genuine Solomon's seal and the neophyte common plate herb grow in the pine forest . Notable endangered plant species in the sandy biotopes are blue-green schillergrass , ear-spoon catchweed , steppe milkweed , sand strawflower , thyme summer root and sand thyme . In recent years there has been a sharp decline or only present in remnants of the mountain hairline , medicinal root , Baden bluegrass and common coniferous herb . Only one specimen of the sand silver sliver was found in 2015. In the meantime, the stocks of the species of sand stone herb , hair awl grass , cone-fruited limeweed , brown-red stendelwort , sand summer root and yellow tooth rust are considered to have been extinct .

There are also several endangered species of mushrooms in the area, including winter stalk bovist and dune stinkhorn .

Eight species of grasshoppers have been identified, including the blue-winged wasteland insect , the spotted cadaver and the steppe grasshopper . 19 species of snail live on the southern slope of the dune, including the endangered species of whorl snail and common heather snail . Numerous invertebrate species live in the top soil layer, including 141 species of beetles.

Impairments

The sensitive sand biotopes are impaired by leisure and recreational use, in particular by footsteps and litter. In addition, the tree and shrub population leads to the decline of rare species through shrub cover, shading and accumulation of humus. On the northern edge, the area was repeatedly eutrophied by manure deposits. In places, highly competitive alien grass species are spreading.
