Foreland of the central Swabian Alb

from Wikipedia, the free encyclopedia

The foreland of the central Swabian Alb , also known as the Mittleres Albvorland , is a natural area (main unit 101) of the Swabian Keuper-Lias-Land in the south-west of Germany .

geography

The Middle Alb foreland covers about 702 km², it extends around 65 kilometers along the Albtrauf from immediately north of Hechingen to Göppingen . To the north, the Neckar and Fils rivers form the borderline to the natural areas Schönbuch and Glemswald , Filder and Schurwald and Welzheimer Wald . To the south the area borders on the Swabian Alb natural area . It is broken down as follows:

  • 101.1 West wing of the Middle Alb foreland
    • 101.10 The Steinlach
    • 101.11 The Steinlach-Albvorberge
  • 101.2 Middle foreland of the central Swabian Alb (Göppingen sheet: "Middle part of the Middle Alb foreland")
    • 101.20 Echaz Alb foreland
    • 101.21 Echaz Bay
    • 101.22 Erms-Steinach-Albvorland
    • 101.23 Neuffen foothills
  • 101.3 Eastern part of the Middle Alb foreland
    • 101.30 Kirchheim Basin
    • 101.31 Lauter-Lindach-Randbucht
    • 101.32 Notzinger plate
    • 101.33 Schlierbacher plate
    • 101.34 Filsalb foothills

The Middle Alb foreland is densely populated with around 504,000 inhabitants (719 inhabitants / km²). The most important cities in west-east direction are Mössingen , Reutlingen , Metzingen , Nürtingen , Kirchheim unter Teck , Uhingen , Göppingen and Eislingen .

geology

The area is mainly determined by the alternation of the Brown Jurassic and Black Jurassic layers. Keuper rocks with their typical tiles now only appear in the valley cuttings under the loess loam-covered, wide field slabs of the lower Lias area. There are also widespread loess-covered layers of liass. The landscape consists of a series of lias plates from about 350 to 400 meters above sea level, which are traversed by several larger bodies of water and their inlets, some of which are clearly cut. A second step also rises above the lower Filder area in the middle Liastonen, crowned by the oil shale , which forms the step surface. Despite the poor quality of the soil here, the oil slate is also largely arable land. In addition to the incised valleys, the landscape is also structured by individual peaks (Braunjura hills). Between these hills and plateaus lies the broad depression zone of the Kirchheim basin at 290 to 350 meters above sea level, which goes back to clearing work during the Ice Age and water. Here there are also some volcanic knolls as special forms, which point to the volcanic activity 17 million to 16 million years ago. Larger forest areas are rare in this landscape, the numerous small settlement areas and the agricultural areas in between dominate. The predominant land use in the landscape is arable farming and extensive orchards around the settlements . Grassland is limited to the pronounced floodplains and the slopes below the Alb eaves . Most of the forests consist of mixed forests.

Protected areas

Numerous nature and landscape protection areas are designated within the Middle Alb foreland . The largest protected area in the landscape is the European bird sanctuary foreland of the central Swabian Alb with around 17,003 hectares in the districts of Esslingen and Göppingen. Other areas are components of various but smaller FFH areas. The largest contiguous German orchard area on the Albtrauf as well as the hillside and ravine forests that exist there are of outstanding importance throughout Europe . The landscape is also characterized by a high proportion of torrent and brook biotopes. A focus of contiguous river biotopes is in the eastern part of the "Middle Alb foreland".
