The Rotböhl even Rottböll or Rotböll called, is an FFH area on the eastern edge of the district Gräfenhausen , City Weiterstadt , in the district of Darmstadt-Dieburg in Southern Hesse . At the same time it is an extensive natural monument with the two sub-areas "Großer and Kleiner Rottböll". The late ice age drifting sand dune was almost destroyed in the past by sand mining and tillage.

location

The Rotböhl sand dune is located in the Untermainebene natural area , Hegbach-Apfelbach-Grund. The protected area is located about 750 meters east of the outskirts of Graefenhausen and borders directly to the south on the “Am Rotböhl” industrial estate. It consists of the northern "Großer Rotböhl" and the southern "Kleiner Rotböhl". The total area is 4,233 hectares. The dune lies between 113 and 118 meters above sea level.

geology

The Rotböhl is part of the approximately 10 kilometer wide belt of drift sand dunes that extends between Darmstadt and Rastatt. The calcareous sands were blown at the end of the last glacial period .

Reasons for protection

The Rotböhl represents the remainder of the largest preserved calcareous drifting sand dune of the Lower Main Plain. It has exceptionally well-preserved sand lawns with blue shrill grass corridors and subcontinental steppe lawns . These biotopes worthy of protection can only be found in a few places in Germany and should be preserved, promoted and developed.

history

The name Rotböhl means "cleared hill". The Rotböhl was mentioned in a document as early as 1610 as a vineyard . During the First World War the dune served as a military training area. From 1933 to 1935, 135,000 cubic meters of sand were removed from the north side for the construction of the Reichsautobahn .

Parts of the dune area were protected on May 10, 1938 as a large natural monument "Großer Rott-Böll". By ordinance of March 31, 1950, published on April 30, 1950, the natural monument was enlarged and identified with the sub-areas "Großer Rottböll" and "Kleiner Rottböll". The area surrounding the natural monument was a landscape protection area from December 1956 , and this was cleared again in November 1963. In 1964 the natural monument in the north was reduced by 1.8 hectares because this area was designated as an industrial area by the municipality of Graefenhausen. The central area of ​​the protected area was still used for agriculture after 1978. After the end of agricultural use, seeds were sown there in 1982 from the “ Griesheimer Sand ” nature reserve . Since January 16, 2008, the natural monument has been protected in the same way as FFH area 601-7303 “Rotböhl”.

Flora and fauna

The vegetation includes pioneer stages, sandy lawns, fallow stages and loose pine stands . The habitat types that are worthy of protection are steppe lawns (LRT 6240), open grass areas with silver grass and ostrich grass on inland dunes (LRT 2330) and subcontinental, base-rich sandy lawns (LRT 6120). Among other things, sand strawflower , ear-spoon catchweed , flat pea vetch , steppe milkweed , blue-green schillergrass , dwarf snail clover , sand timothy , cone-fruited catchweed , sand thyme , early speedwell , ball leek , carthusian carnation , sand -Sommerwurz , Berg-tress , fragrance Skabiose , Upright Ziest and Stipa capillata . Also Baden bluegrass and Sand kochia be mentioned.

The flora and fauna of the Rotböhl have been scientifically investigated for decades. Numerous rare types of mushrooms have been found here. Fifteen species of snail have been identified, including the endangered three-toothed wolverine snail , common heather snail and striped heather snail . The blue-winged wasteland insect , spotted club insect , western teeming insect and vine chickens inhabit the dune. More than 100 species of beetles were recorded. Among the butterflies fall Adonis Blue , aricia agestis , chess and Spurge Hawk on.

Maintenance measures

Maintenance plans have been in place since 1981 to keep the dunes open. The sandy lawns are grazed by donkeys or tended by mowing, and the occurrence of trees is restricted.
