The Upper Kalltal with tributaries is a nature reserve of around 135 hectares in the municipality of Simmerath in North Rhine-Westphalia (NSG identification ACK-084). It is located north of the Simmerath district of Lammersdorf and connects directly downstream to the Kalltal nature reserve . The nature reserve lies entirely in the much larger FFH area DE-5303-302 Kalltal and side valleys . This makes it part of the European Natura 2000 network of protected areas .

The nature reserve is divided into the following sections

Headwaters of the Paustenbach south of Lammersdorf

Here are the two straightened source brooks of the Paustenbach, overgrown with self-sown riparian wood, fatty willows and extensively grazed or fallow, bushy, wet, wet and lean grassland with ear and gray willows . The intensive pastures and poor honey grass pastures on the flat valley slopes are delimited and structured by sloe and old beech hedges . The southern floodplain of the Paustenbachunterlauf is bounded by an old oak - hornbeam hedge on the edge of the valley.

Section of the Kall valley near Bickerath

A 1.7 km long, flat Mulden valley section of the Kall , which is largely still used as pasture grass. Here the Kall is two to three meters wide, with steep banks that are sometimes two meters high. The creek bed is stony and sandy. Fish and numerous insect larvae such as mayflies and caddis flies that speak for the water quality live in the stream . On the northern slopes of the Kall valley near Bickerath there are slate rocks overgrown with lichens and mosses . The nature reserve Kalltal borders in the north and the nature reserve Lenzbach in the west .

Spring basin of the Fischbach northeast of Simmerath

The mostly fallow, flat valley basin of the Fischbach headwaters with well-developed source corridors at the beginning of the straightened source ditches. The source vegetation consists of swamp blood-eye , forest rush stands , slender sedge reeds and groups of ear willow and gray willow, which are located within young fallow grassland with dominant turf . Along the stream ditches that were previously grazed and damaged by footsteps, mostly flood swaths cane.

Bendchen, Lenzbach and Kallbenden

Remnants of the former Venn landscape can be found south of Lammersdorf. There are still flat moors, wet meadow communities and tall herbaceous corridors. The southern individual area of ​​Kallbenden is traversed by the Kranzbach, about one meter wide and 20 cm deep. The stream bed is gravelly to sandy with steep banks. The 100 m wide valley basin has a swampy bottom with herds of rushes, spring swamps and meadowsweet meadows . Another part is traversed by the Kallbach. At the water's edge wet Rasenschmielen stocks are with Bistort to find that in a vast, wet moor grass -Heide with great gentian pass -Population. The Lenzbach , which is its own nature reserve upstream, is another tributary. It flows through a shallow valley basin with clown stocks, which is locally stocked with rush and knotweed herds and small spring swamps. Remains of old windbreak hedges on the edge of the valley. Local regulating measures should be taken here by mowing and clearing the bushes. The crop is removed. The valley is divided into two halves by an anti-tank barrier from World War II. The individual concrete blocks and concrete walls are densely overgrown with mosses and lichen.

Kalltal between Simmerath and the nature reserve Paustenbach

This section of the stream comprises two flat sections of about one kilometer each. The sections are cut from the L 160. To the west the Kall meanders through the meadows to the confluence of the Fischbach, after which it is fallow wet grassland. The latter also applies to the Fischbach. The valleys have not been cultivated since around 1985 and grass clown stocks, flood swaths or reeds and meadowsweet meadows conquer the areas with small spring swamps. The water is not polluted and has a species-rich, characteristic stream fauna. The windbreak hedges are characteristic landscape elements for this region ( Monschauer Heckenland ).

Paustenbach-Vennwiesen west of Bickerath

In 1988 the spruce was removed from two northern plots. The typical vegetation of damp and wet subsoil appeared again: Whistle grass stands are interspersed with bell heather stands in wet depressions and many shallow ditches and bristle grass lawns or calluna heaths on the drier edges. It is planned to remove the remaining spruce as well.

Protection purpose

The Kall Bachtal is an important network axis in the transnational biotope network between the Hohem Venn and the Rurtal . The designation as a nature reserve serves primarily to preserve a near-natural stretch of flowing water as well as the moist to wet grassland and bog areas as a habitat for several threatened plant and animal species and the preservation and development of natural habitats according to Annex I Habitats Directive: beaver , great mouse-eared bat , pond bat , Kingfisher , Whinchat , Lycaena helle , Europe's only found in a few areas, edge ring Fritillary , Small Ampferfeuerfalter , marsh gentian , bog asphodel , plant communities such as underwater vegetation in rivers, Glatthafer- and burnet-Silgenwiesen, wet heaths with Erica , dwarf shrub, gorse -, juniper heaths , grass lawns, rough meadows and pastures, reed beds , riparian forests , etc.
