The Willersinn'sche Grube nature reserve near Dietzenbach (NSG identification 1438013) is located in the Offenbach district in Hesse . It covers 15.15 hectares of forest in the urban area of Dietzenbach .

Area description

The nature reserve is located in a larger, forestry area northeast of Dietzenbach and borders the rain retention basin in the Steinberg district . To the west is the Dietzenbach-Ost industrial park. Other surrounding areas are located in the large landscape protection area of the Offenbach district .

The Willersinn'sche Pit near Dietzenbach is a former gravel quarry. It is named after the Willersinn brothers who mined drifting sand there in the 1950s . Large areas of sand were mined commercially until 1980. The northern part of the pit was then backfilled; the remaining open part has steep slopes. With 185 species, a study documents the greatest diversity of flora and fauna in the Dietzenbach district. The entire area is now forested, and former breeding birds such as woodlark and common pipit are no longer to be found there.

Protection purpose

The purpose of the NSG designation is to secure undisturbed succession processes in the former sand pit so that valuable habitats for the flora and fauna can be preserved or newly created. After the mining of Pleistocene drifting sands by the Willersinn brothers in the 1950s, the subsequent use of the sand pit as a landfill and the abandonment at the beginning of the 1980s, numerous plant species, mainly pioneer plants, took over the changing substrates of sand, clay and loose rock. With 185 species, a study documents the greatest diversity of flora and fauna in the Dietzenbach district. However, alien deciduous trees were planted, the populations of which have a negative effect and impair the succession areas.
