Dirlenbachtal
-3.jpg)
The Dirlenbachtal nature reserve is located in the area of the city of Freudenberg ( Dirlenbach district ) in North Rhine-Westphalia . The area covers an area of 16.2 hectares .
Geography and geology
The nature reserve is located in a low mountain range north of Dirlenbach , a district of Freudenberg. It is assigned to the Siegerland natural area in the Rhenish Slate Mountains . The climate in the urban area of Freudenberg is described as Atlantic, rich in clouds and rain. The mean annual temperature is 8 ° C.
Protection purpose
The designation of the nature reserve was made for the purpose of preserving and restoring a low mountain range, which is mainly used as grassland, and the endangered animal and plant species occurring therein. To be emphasized are:
- extensively used wet meadows with marsh marigolds (Calthion)
- Wet meadows rich in sedges and rushes
- Oat meadows (endangered)
- Großseggenriede (endangered)
- moist tall herbaceous corridors
- Blasenseggenriede (endangered; endangered in Germany)
- Alder forest along streams (endangered), near-natural flowing waters and spring areas
Furthermore, the landscape aesthetic aspect is to be preserved and developed.
Area description
The protected area comprises an area in the Dirlenbach valley, which is characterized by open spaces and grassland use. Numerous biotope types are interlinked here. In the northern section, the protected area includes the spring streams in the forest. The stream is partly lined with spruce trees. In a few places there are near-natural riverbank areas with black alder. The valley floor has sump Beriche and Wet meadow with sedge and bins stock, wet Hochstaudenfluren and softwood stocks ( Weiden on). In the valley floor there is extensive cultivation through grazing. Located higher in the western area are drier areas.
The bank structures of the Dirlenbach are largely natural. The running water system is of good quality, which is indicated by the existence of corresponding fish species (brown trout, minnow) and lovelies.
Flora and fauna
Some of the notable plant species found in the area include:
- Bladder sedge ( Carex vesicaria )
- Broad-leaved orchid ( Dactylorhiza majalis )
- Fever clover ( Menyanthes trifoliata )
- Heil-Ziest ( Betonica officinalis )
- Millet sedge ( Carex panicea )
- Marsh violet ( Viola palustris )
The following animal species are listed as particularly notable in the protected area:
- Dipper ( Cinclus cinclus )
- Brown trout ( Salmo trutta fario )
- Minnow ( Phoxinus phoxinus )
- Blue-winged demoiselle ( Calopteryx virgo )
- Meadowsweet mother-of-pearl butterfly ( Brenthis ino )
- Schachbrettfalter ( Melanargia galathea )
- Grass snake ( Natrix natrix )
- Common Frog ( Rana temporaria )
Hazards
Due to the abandonment of cultivation in particularly wet areas, there is a tendency towards the development of tall herbaceous vegetation and bushes with willow trees. The dereliction of green areas and planting of spruce trees in the northern part of the protected area are also a Gefährund. From ponds disorders can by water extraction and Flore falsification result.
Maintenance and development measures include regulated mowing and grazing in order to preserve the open grassland areas, pushing back bushes (especially sloe), ensuring the continuity of waters and the dismantling of ponds. In the long term, coniferous wood stocks are to be converted into black alder forests that accompany water bodies.
