Purple calamine pansy

The Waschebach / Tieberg nature reserve is located east of Meerhof in the urban area of Marsberg in the Hochsauerlandkreis . The north-eastern edge of the NSG forms the boundary between the Hochsauerlandkreis and the Höxter district . In the district of Höxter the nature reserve Bleikuhlen and Waschebachtal borders directly . The protected area was designated as a nature reserve (NSG) in the Marsberg landscape plan in 2008 and is 84.93  hectares in size. It is named after the brook Waschebach and the mountain Tieberg which are partly within the NSG. The NSG represents a sub-area in the FFH area Bleikuhlen and Waschebachtal (Natura 2000-Nr. DE-4419-303) in the European protected area system according to Natura 2000. The specialty of the nature reserve is the violet calamine pansy ( Viola guestphalica ).

description

The NSG covers the source area and the middle course of the Waschebach as well as the Schwarzbach flowing in from the left , as far as they are in the Hochsauerlandkreis. The southern source areas of the Waschebach were used as grassland for a long time. They are sometimes very wet to boggy. Some of these meadows have been afforested in the last few decades. The afforestation was mainly carried out with spruce . The northern arm of the wash stream has cleared a deep cut in the wooded Tieberg. Below this source fan, the water stream is two to three meters wide and is very natural thanks to the bank breaks, steep walls and gravel banks. It is largely bordered by an alluvial forest made of alders. The source region of the Schwarzbach has largely disappeared under the earth movements of calamine mining in the lead pit near lead washing and the A 44 motorway . Otherwise it forms a structurally rich river. The water bed is deepened by the discharge of surface water from the A 44. The valley flanks included in the NSG are often covered with spruce. Following its confluence with the Waschebach there is a moderately moist, sedge-rich grassland fallow with a supraregional significant occurrence of rare plants. Floristically outstanding is a small forest meadow on the edge of the valley as a place where heavy metal vegetation of a heavy metal lawn grows , which can be attributed to ore mining in the Schwarzbach headwaters. Below the stream winds through a closed, predominantly spruce forest area.

The Schwarzbach as well as the middle course and the southern source areas of the Waschebach are parts of the FFH area Bleikuhlen and Waschebachtal . The riparian riparian forests and the adjacent grove and beech forests are so-called habitats of community interest according to the Habitats Directive. In addition, the near-natural, large-scale and, moreover, state-owned beech stocks of the Tieberg were included in the NSG, especially since the northern source of the Waschebach is embedded here.

Purple calamine pansy

In the NSG the violet calamine pansy ( Viola guestphalica ) occurs. The violet calamine pansy occurs worldwide only in one place of growth in the border area of ​​the Paderborn, Höxter and Hochsauerlandkreis districts. The entire occurrence is located in the FFH area Bleikuhlen and Waschebachtal of 71 hectares. One of the main protection goals of the area is, in addition to the preservation of the existing heavy metal lawn , the networking and restoration of heavy metal lawn in suitable locations in the protected area. The FFH area consists of parts of four nature reserves (NSG). These are the areas of the Bleikuhlen nature reserve in the urban area of Lichtenau ( Paderborn district ), which were first designated by the Detmold district government in 1969, and the Bleikuhlen and Waschebachtal nature reserve in the Warburg district ( Höxter district ), as well as the two laundry areas in 2008 from the Hochsauerlandkreis . Tieberg and the Bleikuhle nature reserve in the Marsberg urban area . The species grows there in open, extremely low-nitrogen grassland naturally contaminated with heavy metals on dry and semi-dry grassland in partially shaded to sunny places in heavy metal grass. In addition to the lead hollows, the former opencast mine, and the spoil dump, it grows below the lead hollows in a meadow in the Waschebach valley that is contaminated with heavy metals. In the NSG Waschebachtal / Tieberg, the two meadows with the occurrence of the violet calamine pansy are mowed annually by the Association for Nature and Bird Protection in the Hochsauerlandkreis (VNV) to prevent encroachment or reforestation and thus the disappearance of the species.

Protection purpose of the nature reserve

Preservation and optimization of near-natural spring and brook habitats including the accompanying floodplain and swamp forest communities; Securing the traditional use of grassland on sites at risk of abandonment through contract offers for the maintenance and improvement of this biotope mosaic made up of wet and wet grassland areas; Protection of the beech and mixed forests included and their further development into stocks that correspond to the Habitat type hornbeam beech forest; Ensuring the coherence and implementation of the European Natura 2000 system of protected areas .

Sawn blackthorn bushes on the lower forest meadow

In the middle area of ​​the NSG, at the end of the 1980s, some areas of wood, especially black thorn, were cleared by a private company on behalf of the Lower Landscape Authority of the HSK. The VNV has carried out maintenance work in grassland areas in the NSG every year since the 1980s. Larger areas are mowed with a single-axle mower. The work is carried out on Saturdays by the members of the association and the VNV care team. For the maintenance work there is money from the cultural landscape maintenance program (KLP) of the Hochsauerlandkreis.

In order to enlarge the lower meadow area of ​​the NSG, the Biological Station Hochsauerlandkreis began removing blackthorn bushes in early 2014 .
