natural reserve

The Theiss valley is located in the natural area of the Wiesbaden high Taunus (part of the High Taunus ) in the Rhine-Taunus nature park . The nature reserve, designated on July 31, 1992, consists of two parts and has a total size of 49.57 hectares . The nature reserve is part of the 82.51 hectare FFH area “Theiss Valley of Niedernhausen with adjacent areas”, which belongs to the Natura 2000 network. The FFH area also includes the meadows in the valley below the nature reserve up to approx. 250 m above the Theiss valley bridge , as well as the slopes to the north with old farmland and orchards , leisure properties , Christmas tree cultivation and an old landfill. Surrounded the nature reserve of FFH area is beech forests north of Wiesbaden , the parts lying on the Wiesbaden district are also part of the conservation area town Wiesbaden . The biotope complex, which has been legally protected since 1996, is located within the protected area, the “grassland-fresh wood complex on and in the Theiss valley west of Niedernhausen” with several individual biotopes .

The valley areas of the area are old agricultural areas. The valley played an important role in drinking water production from around 1900 , in the valley there are some smaller water abstraction systems , and in north-south direction it is crossed by the Kellerskopfstollen belonging to Wiesbaden's water supply , the mouth of which is southwest of the Kellerskopf near Wiesbaden-Rambach in the valley of the Rambachs is located. Because of the protection of the groundwater , the meadows in the middle and upper valley were probably never fertilized and grazed, but were used for the production of hay and the grazing of game . However, this use ended in the course of the 20th century, so that some meadows became forested.

The purpose of the protection is to preserve and secure almost its entire length of a forest meadow valley typical of the Hoher Taunus natural area with endangered animal and plant species. The valley contains meadows with bristle grass , pipe grass , oats , marsh marigolds , meadow foxtail and large meadow button , as well as swamps with rushes and brown sedges . In addition, there are wooded areas with black alders and ash trees along the naturally meandering Theissbach. The aim is the extensive use and maintenance of the valuable grassland, the pushing back of fallow land, the ecological upgrading of the micro-bodies of water and the medium-term transfer of the spruce stands to alder-ash forests. Protect values species are the brook lamprey and the dark Burnet-Large Blues , a butterfly .

The protected area is looked after by the Forsthaus Chausseehaus von Hessen-Forst .
