The Bleikuhle nature reserve with a size of 1.16 hectares is located south of Blankenrode (belongs to Lichtenau in the Paderborn district ) in the urban area of Marsberg in the Hochsauerland district . It was designated as a nature reserve (NSG) in 2008 with the Marsberg landscape plan . In the east, the Bleikuhlen nature reserve and the Waschebachtal in the urban area of Warburg in the Höxter district are directly adjacent . In the southwest, the federal motorway 44 forms the border. The NSG forms the border between the Hochsauerlandkreis and the Höxter district and Paderborn district in the north and east. The NSG represents a partial area in the Fauna-Flora-Habitat (FFH) Bleikuhlen and Waschebachtal (Natura 2000-Nr. DE-4419-303) in the European system of protected areas according to Natura 2000. It is a former ore mine in which from the 12th Century until 1745 lead ore was mined. Galmei was mined in the second half of the 18th century to the beginning of the 20th century . The area of the ore mine is protected here in three different cities and districts because the borders meet here. The specialty of the nature reserve is the violet calamine pansy ( Viola guestphalica ).

description

The NSG records the dump of the ore mine which is directly adjacent in the district of Höxter and in the district of Paderborn. The open-cast mine is protected in the Bleikuhlen and Waschebachtal nature reserve (Höxter district) and in the Bleikuhlen nature reserve (Paderborn district). In the NSG there is a heavy metal lawn with the violet calamine pansy.

Purple calamine pansy

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 is made up of parts of four nature reserves. These are the areas of the Bleikuhlen nature reserve in the urban area of Lichtenau , designated by the Detmold administrative district in 1969, and the Bleikuhlen and Waschebachtal nature reserve in the urban area of Warburg, as well as the two areas of the Waschebach / Tieberg nature reserve designated in 2008 by the Hochsauerlandkreis and the one discussed here Bleikuhle nature reserve . The species grows in open, extremely low-nitrogen grassland naturally contaminated with heavy metals on dry and semi-arid grassland in partially shaded to sunny spots 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.
