Mixed forests nature reserve south of the Effenberg

The nature reserve mixed forests south of the Effenberg with a size of 39.7 ha is located northwest of Hachen in the urban area of Sundern (Sauerland) . The area was designated as a nature reserve (NSG) by the district council of the Hochsauerlandkreis in 2019 with the Sundern landscape plan . The NSG goes at one point to the city limits of Arnsberg . When the Sundern landscape plan was re-established in 2019, the NSG was formed from the Effenberg nature reserve with 11.4 ha, the Grasberg nature reserve with 7.3 ha and areas of the Sundern nature reserve between the two protected areas and those located to the south-west. The nature reserve Talwiesen northwest of the Sauerlandklinik borders directly to the south.

description

The NSG is a forest area with large old beech stands with areas of other tree species and rock areas.

The landscape plan explains the nature reserve: “The NSG extends from the upper reaches of the Asbeck brook and the mixed beech forests adjoining its western valley slopes in the west, through the structured and species-rich beech forests on the moderately steep to steep slopes of the Effenberg to the near-natural mixed beech and oak forests in the vicinity of a nameless valley west of the Grasberg summit in the east. Overall, near-natural beech forest with a heterogeneous age structure (mostly as high forest with up to 200-year-old beeches) on the slopes in differently exposed locations of the NSG. Many trees reach a large diameter. Other tree species are added to the individual trunk. Beech trees with natural regeneration appear scattered. The herbaceous layer is lush, often occurs in clumps and herds and in some areas reaches high degrees of coverage. Towards the east, however, it is increasingly completely absent. Natural beech regeneration is also less developed here. The comparatively large complex of indigenous deciduous forests is made up of various beech forest societies, some of which are more or less old and deadwood: depending on the exposure and the geological subsoil, the beech forest merges into a species-rich woodruff or pearl grass beech forest. Often the woodruff beech forest is only sprinkled in small areas, generally the transitions are fluid and characterized by diverse penetrations. To the east, oaks are mixed with the beeches to a greater or lesser extent. Due to the calcareous locations for the region as a whole, the herbaceous layers of the structurally rich, indigenous beech forests with numerous regionally rare plant species as well as the natural rock formations of various geological origins make the area particularly important within the regional biotope network. In the west, the Asbeck brook, after the narrow notch valley widens, is lined in parts by a well-developed alder forest accompanying the brook. On the Effenberg to the east, the beech forest is divided by several eight to ten m high, steep to stepped cliff complexes made of gray and red Kramenzel and slab limestone. The cliffs are characterized by a lush, fern and moss-rich rock vegetation. Rock cliffs also extend to the east of the NSG on the northwest slope of the Grasberg plateau, here over approx. 100 m in a north-south direction. They consist of red and green Upper Devonian cypridene slate on the border with gray and red Kramenzel and plate limes. The steeply sloping cliffs, which are up to 15 m high, are also covered with vegetation rich in ferns, moss and lichen, with ivy growing in some places. A few summer linden trees stand out among the few trees that are stagnant on the rock . To the south there are some more rock cliffs only up to 4 m high. "

Protection purpose

According to the landscape plan, it was designated as:

"Protection, maintenance and development of a structure and species-rich deciduous forest complex with significant limestone locations, broken rock cliffs and with species-rich shrub and herb plant communities with z. T. biogeographical importance; "
"Protection of geoscientific regionally important rock formations;"
"Preservation and optimization of a heterogeneous forest habitat complex and its special, typical flora and fauna."
"The NSG also serves to sustainably secure habitats that are particularly worthy of protection according to § 30 BNatSchG and the occurrence of rare animal and plant species."

Spruces in the NSG

Deviating from the prohibition for forest nature protection areas in the landscape plan area "reforestation with coniferous trees or other tree species not naturally native within the area on the respective location", coniferous wood cultivation with one is still allowed on two composite areas of 0.59 ha and 0.42 ha in the NSG Area share of maximum 20% is permitted.
