The Eriskircher Ried is a nature reserve (NSG number 4.020) in the area of ​​the municipality of Eriskirch and the city of Friedrichshafen, designated by ordinance of July 8, 1939 as well as an extension and new ordinance of October 10, 1983 by the Ministry of Economics, Medium-Sized Enterprises and Transport and the Tübingen regional council . It is the largest nature reserve on the northern shore of Lake Constance .

The protected area is partly identical to the also designated FFH areas " Bodenseeuferlandschaft east Friedrichshafen " (SG-No. 8423341), " Schussenbecken and Schmalegger Tobel " (SG-No. 8323341) and the European bird sanctuary " Eriskircher Ried " (SG- No. 8323-401).

location

The approximately 552 hectare (ha) nature reserve Eriskircher Ried is located between the Rotach and the Schussen confluence with Lake Constance, west and south of Eriskirch and east of Friedrichshafen, in the Lake Constance district of Baden-Württemberg in Germany .

Protection purpose

The main protection purpose is the preservation of the unique natural area between the Schussen and Rotach estuaries with the extensive shallow water zone of Lake Constance, the reed areas, the reed areas, the oxbow lakes and the cultural landscape elements as a particularly natural breeding, resting and feeding area for many rare, to Waterfowl , insects , fish , amphibians and reptiles , some of which are threatened with extinction , with species-rich vegetation, in particular a diverse, particularly rich, typical flat moor flora with some species that are threatened with extinction.

geology

In the Würm Ice Age , about 20,000 years ago, who coined the Rhine - foreland glaciers the landscape of today's Lake Constance. Sediments from the lake and the rivers that have been deposited since the last ice age form the subsoil of the reed; in some places there is moraine material .

  • Iris flower

  • Riedwiese

  • Sedge meadow with white stork

  • The shot just before it flows into Lake Constance

Habitats

The distribution of different plant and animal communities in the Eriskircher Ried is mainly influenced by the altitude above the mean water of Lake Constance and the associated different lengths of flooding during high water. Today we distinguish four habitats.

  • The backwater
By their very nature, Schussen and Rotach did not flow straight to Lake Constance, but formed numerous loops of the river. These were straightened by humans at the beginning of the 20th century and cut off when they were shot. The so-called still or backwater emerged.
  • The shot with the floodplain forests
Alluvial forests are azonal forest communities that are strongly influenced by flooding and high groundwater levels .
  • The litter meadows
Litter meadows are among the most valuable biotopes today . The meadows near the lake in Eriskircher Ried are flooded for weeks almost every year so that they could not be used as fodder meadows; they were mowed in the winter half of the year, and the mowing material was used as litter (from which the name "litter meadow" is derived) in stables.
  • The bank area with shallow water zone
The reeds and reeds , which are flooded in summer, are very flat and fall up to a kilometer out, are the nurseries of fish and water birds. Nutrients, light and heat promote plant growth here, so this shallow water zone is the most productive area of ​​the whole lake. When the water is low, large areas of mud emerge, which are valuable resting places for curlews and other waders .

Conservation Center

Conservation Center

In 1992, the Eriskirch Nature Conservation Center Foundation was set up in cooperation with the state of Baden-Württemberg, the Lake Constance district and the Eriskirch community . In the former station building the visitor gets fascinating insights into the natural landscape of Lake Constance and the beauty of the nature reserve "Eriskircher Ried". In addition to various exhibitions, the nature conservation center also regularly organizes guided tours under expert guidance, lectures and seminars.

Lake Constance Path

From the mouth of the Rotach, the route of the Lake Constance Trail, which was already signposted in 1997 , leads from Friedrichshafen out of town, parallel to the banks to Eriskirch. Two viewing platforms and thirteen stations with information boards convey the context of the Eriskircher Ried and give explanations on various topics such as "animals", "plants", "alluvial forest" and "shore zone".
