WEG Belauer See

Lake Belau water catchment area

Sub-area dominated by stretches of water in the young moraine landscape of East Holstein

The catchment area of Belauer See (Lake Belau) covers an area of about 4.5 km2 and is located in the north of the sampling area Börnhöveder Seengebiet (Bornhöved Lake District). It includes Lake Belau and the river Alte Schwentine, which is the lake’s tributary and effluent. The lake has a surface area of 1.13 km2, a volume of 10.18 mio m3, and a mean and maximum depth of 9 and 25.6 metres, respectively. The anthropogenic activities in the area are restricted to fishery, forestry at the western lakeside and agriculture at the northern, eastern and southern shores.

Within the sub-area are sampling sites for beech, spruce, pigeon eggs, earthworms, and soil and a common site for zebra mussel and bream.

Sampling site

Specimen

  • Common mussel species as invasive animal in rivers and lakes with high information level for water pollution
  • Bioindicator in rivers and lakes
  • A major primary producer in semi-natural and anthropogenic affected ecosystems.
  • As the most dominant deciduous tree species in Central Europe, it plays a significant role in most nearly natural and also anthropogenically influenced forest ecosystems up to an altitude of 1100 m.
  • A pigeon species home in nearly every city.
  • As an organism living at ground level, it is a major driver of the decomposition of organic material (e.g. plant litter).
  • Soil is livelihood and biosphere for humans, animals, plants and soil organisms. All the substances brought in are transported, transformed and/or accumulated in the soil.
