The Iberg nature reserve is a 23.69 hectare nature reserve (NSG) in the urban area of Winterberg east of Siedlinghausen on the western slope of the Iberg . In 2008 the area was designated as an NSG by the Hochsauerlandkreis in the Winterberg landscape plan .

Habitats

In the NSG there is a large area of ​​near-natural beech forest on a diabase underground on the steep western slope of the Iberg. The grove beech forest consists of medium to thick tree wood and is locally interspersed with standing dead wood. Individual sycamore elms and sycamore maples stand on the diabase log heaps . The site conditions are similar to richer ravine and rubble forests, as the occurrence of the silver leaf shows.

Some rocks come to light on the west-exposed Iberg slope. The NSG encloses large parts of the former quarry on the Iberg. The northern edge of the quarry is included in the NSG. The rock walls there are approx. 20 m high. The contact zone with the Middle Devonian slate of the Fredeburg strata and the diabase is located in the quarry. The slates are silicified through contact with the volcanic rock and turned into chert. Due to the geoscientific significance of this rarely seen constellation, part of the quarry wall was included in the NSG delimitation. In the south-west of the NSG, old heaps were included which, due to their location diversity and succession stages, provide habitats for amphibian, reptile and insect fauna.

fauna

In the mountain lake of the former quarry just outside the NSG there is a mass occurrence of the common frog . Peregrine falcon and eagle owl brood on the rocks in the past .

Protection purpose

The nature reserve was designated for the preservation and development of a forest and as a habitat for endangered animal and plant species. As with other nature reserves in Germany, the protection designation indicated that the area became a nature reserve “because of its scenic beauty and uniqueness”. The NSG specifically for the preservation and optimization of a relict beech population and as a refuge habitat for the typical inventory of species of a richer beech-beech forest. Protection of the special habitat function of diabase block rubble and cliff areas, furthermore securing of stepping stone biotopes as cores of a possible long-term re-expansion of the native, autochthonous hardwood stocks in connection with other NSG in this natural area.
