Nature reserve Im Sümpfel

from Wikipedia, the free encyclopedia

The nature reserve Im Sümpfel with a size of 11.4  hectares is located east of Amecke and north of Illingheim in the urban area of Sundern (Sauerland) . The area was designated as a nature reserve (NSG) with an area of ​​11.7 ha for the first time in 1993 with the Sundern landscape plan by the Hochsauerlandkreis . When the landscape planner Sundern was reorganized in 2019, the NSG was again identified and reduced in size. The NSG is directly adjacent to the Illingheim development in the south. In the north and west, the landscape protection area borders the outskirts and agricultural priority areas in the landscape between Amecke, Bruchhausen, Allendorf and Stockum , and in the northeast and east the landscape protection area Sundern .

description

The NSG is the shallow limestone ridge swamps which is overgrown with structure and species-rich deciduous forest. There are smaller former quarries in the area. The landscape plan leads to the nature reserve:

“A woodruff beech forest rich in old wood is surrounded in the northeast and southwest by secondary oak-hornbeam forests (partly with overhangs) that have arisen through the use of coppice; In the mostly lush, species-rich herb layer of all mixed deciduous forests, numerous, regionally rare limestone plants stand out. "

According to the description in the specialist information system of the State Office for Nature, Environment and Consumer Protection North Rhine-Westphalia , the red kite appears in the NSG . In the NSG there is the Illingheimer cave .

Illingheimer cave

The entrance to the Illingheim cave was uncovered in 1851 during work in a small quarry. In 1855 two articles appeared and in 1871 one article in magazines describing the cave in reports on caves in the Sauerland. After 1871 it is mentioned several times in the literature that the Illingheim Cave had collapsed. Between 1975 and around 1990 there were several attempts to find the cave. From 2010, new attempts by members of the working group Höhle und Karst Sauerland / Hemer began . In February 2012, with an outside temperature of minus 14 degrees, a 3 cm area of ​​moist soil was found on the floor of a former quarry, while the surroundings were frozen as hard as rock. It was assumed that this was caused by rising warmer cave air, as the temperature in caves in the Sauerland region was 8 to 9 degrees. After some fist-sized stones had been cleared aside, a clearly perceptible flow of warm air began. In October 2012, a 4 × 7 m and 3 m deep search trench was dug on seven days, and the cave entrance was found. In April 2013 a 3 m high shaft was built above the cave entrance made of well rings up to the level of the quarry floor and a steel door was installed at the top for safety. The search trench was then backfilled except for the safety shaft. From the entrance a narrow crevice leads into the depths of the cave, either diagonally or vertically. The end of the cave is 61 m below the entry level. At the beginning of 2015, the length of the cave was 120 m, with the deepest point of the cave covered with rock rubble. In the cave there are stalactite formations such as button sinter, large-scale wall sintering and smaller sinter flags. During investigations, fragments of bones from Ice Age animals were found.

Protection purpose

According to the landscape plan, it was designated as:

  • "Protection, preservation and development of a diverse, predominantly natural forest area with a species-rich layer of herbs on regionally rare limestone site and its communities with z. T. biogeographical importance; "
  • "Protection and preservation of a stepping stone biotope for scientific, natural history, geological and regional reasons."
  • "The NSG also serves to sustainably secure the occurrence of rare animal and plant species."
