Schierl's pond
Schierls Teich is a heather pond in the Große Heide between the Gütersloh districts of Avenwedde-Bahnhof and Friedrichsdorf .
The 50 × 80 m pond, which was probably created by blowing out the wind, is located in a small dune area. Scots pine ( Pinus sylvestris ) in particular grow on the up to 3 m high dunes . Most of the trees show poor growth and hardly rejuvenate. In some places the oak-birch forest, which is appropriate for the location, grows through. The herb layer is largely made up of bilberry ( Vaccinium myrtillus ) and wire smear ( Deschampsia caespitosa ). To brighter places there are heather ( Calluna vulgaris ) and bristle grass ( Nardus stricta ).
Since the water is only about 30 cm deep, it dries up completely every summer. It is framed by a wreath of pipe grass ( Molinia caerulea ). In the past, some floristic rarities grew on its edge, in the midst of the somewhat elevated pipe grass population in the western half , including:
- Brown Schnabelried ( Rhynchospora fusca )
- White Schnabelried ( Rhynchospora alba )
- Middle sundew ( Drosera intermedia )
- Cottongrass ( Eriophorum spec. )
Until the 1970s, the dominant plant in the water area was the peat moss (Sphagnum spec.).
As a result of increasing eutrophication and the increased spread of pipe grass, these species have now completely disappeared. The rib fern ( Blechnum spicant ) was also found at the foot of a fallen Scots pine . In the valley , which used lawn of reddish overcrowded onion rush ( Juncus bulbosus was covered), numerous nutrient-loving species have settled, including Tonquil ( Juncus effusus ), bittersweet nightshade ( Solanum dulcamara ) and Wolf Trapp ( Lycopus europaeus ). At the deepest point there is a large population of common swamp rush ( Eleocharis palustris ).
Another version of the origin of the pond says that peat was extracted there for a while in the 19th century, probably as fuel for a small brick factory. The pond is also called "Torfkuhle" by the locals. Until the 1930s, when the water level was high, it extended almost twice as long in a narrower band to the west (WSW). Corresponding, silted-up depressions can still be found there today. This area was separated by the construction of a forest path.
