Lake in the Heiliges Meer nature reserve - Heupen |
|
The Heideweiher is a shallow still water in the nature reserve Heiliges Meer - Heupen .
location
The nature reserve has several sinkhole lakes and vast heathland. This area is particularly worthy of protection due to its particularly nutrient-poor soils and bodies of water, since under these conditions there is a high biodiversity of rare animals and plants.
Like the Erdfallsee lake, the Heideweiher lies exclusively on the soil of the municipality of Hopsten in the Tecklenburger Land . The Uffeln district of the city of Ibbenbüren begins just a few meters southwest of the nature reserve . To the west is the village of Obersteinbeck , which belongs to Recke .
Emergence
The origin of the heather pond has not yet been properly clarified. In the past it was assumed that it was formed by a shallow depression like several ponds in the nature reserve. But it could also have been created by blowing sand, as is "usual" for heather ponds.
Waters
Until a few decades ago, the heather pond was a periodically drying, oligotrophic (mineral-poor) body of water. Like most pools in the nature reserve, it is fed by rainwater and has no contact with the groundwater. This separation from the groundwater takes place by means of local stone banks running under the area , which form a water-impermeable layer.
By preventing artificial, dehydrating conditions, his water balance stabilized and he increasingly developed a dystrophic character. This dystrophic character says that the water increasingly accumulates humic acid and slowly develops into a fen. Increasing siltation due to the no longer possible rotting process accompanies this development. The soil type Dy , a nutrient-poor, hummus-infused brown mud soil, accumulates on the floor of the heather pond.
Living things in the lake
The hydrochemical change in the lake brought about a change in the flora. Oligothraphent species such as the strandling and the water lobelia were replaced by dystrohphente.
