Moors Around the Tielenau

In the penultimate Ice Age 250,000 years ago, the three moors Dörplinger Moor, Österborsteler Moor and Käthnermoor, which are separated from each other, were formed.Beautiful scenic paths and the route of the old narrow-gauge railway run through the moors.

Large-scale moorings of the post-glacial period
The lowlands of the Tielenau and the Schalkholzer Au owe their formation to a brief glacial advance during the penultimate Ice Age, i.e. around 100,000 to 200,000 years ago. The generally shrinking inland ice temporarily formed tongues of glaciers here that advanced westward and, after melting, left behind ice tongue basins with marginal heights.
In the post-glacial period, large areas of moorland formed in these lowlands with several raised bog cores, the Käthner or Tellingstedter Moor, the Österborsteler and the Dörplinger Moor (from west to east), which are separated from each other by the Tielenau and the isolated Geestinsel "Fieler Knüll". are.
Typical high moor vegetation has not been preserved in any of the three moors. The Käthnermoor with its many water-filled former peat pits has been degraded the most and the surrounding vegetation has developed into a wet forest with birches, aspens and alders.
The majority of the Dörplinger Moor is also heavily overgrown; open areas here are largely covered with moor grass bulbs. The Österborsteler Moor also offers larger and sizeable open spaces; However, here too, moor grass fields have developed from the raised bog areas through degradation and strong drainage. These moors are still crossed by the dam of the former small railway, which is used as a cycle path and footpath.
In the past not only gravel was extracted from the Fieler Knüll, but in some places also rich clay for the needs of the Tellingstedt potteries.
