Weckers Heideteich

Weckers Heideteich is a natural monument in the area of ​​the Paderborn district of Sande . It has a size of about 0.5 hectares .

Location and description

Weckers Heideteich is located in the middle of the Sander Bruch, about 300 m northwest of the Wüseke farm. While the natural monument is bounded in the north by Sander Bruch-Straße, the former route of the Sennelager-Ostenland railway line marks the southern border of the area. Contrary to what the name suggests, however, it is not an artificially created body of water, but a heather pond that was probably created by blowing out wind . It once contained oligotrophic water and dries out completely almost every summer.

Flora and vegetation

In the 1960s the area still had floating leaf societies, wet heaths and raised bog societies. With the rosemary heather ( Andromeda polifolia ) and the sheathed cottongrass ( Eriophorum vaginatum ), two typical raised bog species occurred at that time , which prove the former lack of nutrients in the area. Over time, the pond grew more and more over with willow bushes . There was a gradual eutrophication of the area from the adjacent arable land , which ultimately led to a large-scale displacement of the typical heather and bog vegetation. Today, plant species dominate that tend to be bound to a medium nutrient content. In 1989/90 extensive maintenance measures were carried out in the area and most of the willow bushes were removed. In addition, the topsoil was partially removed and the pond deepened. This enabled a number of rarer species such as the bell heather ( Erica tetralix ) and the mean sundew ( Drosera intermedia ) to spread or settle again.

The numerous floristic features of the area include or were:

Brown sedge ( Carex nigra )

Fever clover ( Menyanthes trifoliata ), still in 1991, then extinguished

Gray sedge ( Carex canescens ), according to Ottenströer in 2007

Middle sundew ( Drosera intermedia ), still 2007

Rosemary heather ( Andromeda polifolia ), long extinct

Vaginal cottongrass ( Eriophorum vaginatum ), extinguished

Beaked Sedge ( Carex rostrata ), still 2007

Marsh skullcap (Scutellaria galericulata)

Pennywort ( Hydrocotyle vulgaris ), 2007

White water lily ( Nymphaea alba ), extinguished

fauna

Numerous species of dragonflies have been found in the area, including (according to Ottenströer 2009) the following Red List species : Banded demoiselle , brown damsel , shiny damsel and little damsel . Formerly belonged water rail , moorhen , mallard and reed bunting to breeding birds.
