Westallgäu hill country

from Wikipedia, the free encyclopedia

The Westallgäuer hill country is a glacially influenced landscape in the southern German states of Baden-Wuerttemberg and Bavaria as well as a natural space (033) in the pre-alpine hills and moorland (southern foothills of the Alps ).

location

Near Simmerberg (left: Balzer Berg)

The Westallgäu hill country lies between the Lake Constance basin in the south-west, the Upper Swabian hill country with the Altdorf forest in the north-west and the Riss-Aitrach plates in the north and north-east. From the Adelegg in the east to the Pfänder in the south, it meets the pre-alpine mountain ranges of the newer natural spatial unit Nagelfluhhöhen and Senken between Lake Constance and Wertach with Adelegg (up to 1129  m ), Sonneneck ( 1105.8  m ), Riedholzer Kugel ( 1065.5  m) ), Laubenberg ( 918.8  m ), Balzer Berg ( 920  m ), Sulzberg ( 1041  m ) and, beyond the Rotach , the Pfänder (at the Hirschberg 1095  m ).

The big order 664 square kilometer area covers parts of Lake Constance district and the counties Ravensburg and Lindau . The landscape ranges from 500 to a height of 700  m above sea level. NN . It is drained via the Argen and Schussen as well as their tributaries and Lake Constance to the Rhine .

Natural structure

The main natural area of ​​the West Allgäu hill country was identified for the first time in the years 1953 and 1954 in the second delivery and the first mapping of the handbook of the natural spatial structure of Germany . At that time it had an area of ​​909.16 km², which also included parts of the newer pre-Alpine unit Nagelfluhhöhen and sinks between Lake Constance and Wertach , as well as the units 030.043 / 047/048 and the north of the units 030.049 / 050/051, which were ultimately attributed to the Lake Constance basin. According to the limits of the detailed classification 1: 200,000 by Hansjörg Dongus on sheet 186/193 Lindau / Oberstdorf in 1991, which was also largely taken over in BW by the State Institute for the Environment, Measurements and Nature Conservation Baden-Württemberg (LUBW), there is an area of around 664 km², of which about 548 km² in BW and 116 km² in BY.

It is structured according to the Lindau (Dongus) sheet as follows:

Dongus had placed the edge channels in the southeast to the Riss-Aitrach-Platten (041); However, according to the current convention of the Institute for Regional Studies, which LUBW also follows, they are only counted among the old moraine units from where they are lined with old moraine plates.

Emergence

In the Würm Ice Age , about 20,000 years ago, coined the Rhine - foreland glaciers the landscape. Drumlins , young moraine areas , reeds, moors and glacial molass ridges represent the typical terrain forms here today. In the area of ​​the ground moraine , loam and sandy loam predominate, in the meltwater channels gravel and sand.

Protected areas

Numerous nature and landscape protection areas are designated within the Westallgäu hill country , especially marshland and moorland areas ( reeds ) and bodies of water ( ponds , ponds, springs). The larger of these areas, such as the Bodenmöser , are placed under special protection as FFH and / or European bird protection areas.

Protected area shares % Total landscape area
FFH areas 8.97
European bird sanctuaries 1.57
Nature reserves 3.89
Other protected areas 0.00
Effective proportion of the protected area 9.64

  4. ↑ a b The hill country as it is recognized today has not yet been "officially" measured, but it can be measured using map services; Estimates result from the still pre-alpine mountains with included value in the handbook of the natural spatial structure of Germany (909.16 km²) and the size of the slightly different extent of the BfN profile (681 km²); the Baden-Württemberg portion, together with the small Adelegg portion of the federal state, comprises 582 km² - minus the 34.3 km² (measurement) BW-Adelegg, this makes 548 km². In addition there are 116 km² (measurement) in Bavaria and minimal proportions in Vorarlberg .
