Steverquelle nature reserve

Basic source of the Stever with forest accompanying the stream

The nature reserves Steverquelle , more precisely Stever (north) and Stever (south), are located on the upper reaches of the Stever to the northwest and southeast of the Stevern peasantry belonging to Nottuln . The nature reserves are intended to protect the deeply incised, poorly straightened and naturally overgrown spring stream.

The 13.9 hectare area with the identification COE-014 goes from the anthropogenic , nitrogen-rich and densely overgrown spring pond to the historic Stiftsmühle and includes around 1,500 meters of stream and the adjacent wet meadows on the right and left up to a width of 250 meters . The Stever is also fed from several heavily pouring ground sources and seepage points. Most of it runs along the border between forest and pastureland and is covered with large, sometimes multi-stemmed riverbank trees such as alders and willows . The banks are rich in moss, the meadows moist and in places interspersed with Großseggenried . In addition, the watercress and marsh marigolds can be found in the moist tall herbaceous corridor .

The Westfälische Wilhelms-Universität in Münster and its Institute for Geology and Paleontology have supervised several theses on the topic of "Conservation, research and development of the sources in the natural and adventure area of the Baumberge". For example, the Stever spring was classified in value class 3 (found animal world inhabited by springs but not typical for springs) and the origin of the water from the Stever spring was clarified, namely directly from the Westerberg.

In 2007, the endangered caddis fly was discovered in the sources .

Stever (south)

The 23.8 hectare area with the identification COE-071 begins behind the main settlement "Stevertal" on the L 842 and protects around 2,300 meters of the flowing water with up to 200 meters wide edge zones up to the farmers "Heller". The brook has longer straightened stretches and partly ungrown bank areas. Nevertheless, there are many natural elements such as under-washed trees, old white willow and floodplain communities .

description

The majority of the two nature reserves are only used extensively within the framework of contractual nature conservation.

The following types of biotopes can be found in the areas:

near-natural flowing waters
swell
Wet grasslands
Bank and field trees

The nature reserves were not only established for the preservation of communities and biotopes of the wild animal and plant species and to safeguard the natural balance or to ward off harmful effects, but also because of the special characteristics and outstanding beauty of this part of the landscape and for scientific, regional and natural historical reasons .
