Langes Luch

The Langes Luch und Dachsheide nature reserve lies in Berlin's Dahlem neighborhood, on the edge of the Grunewald forest. It is a swampy depression in a glacial channel, connected to Grunewaldsee by a canal at its eastern end. Originally protected in 1960 as a 15-hectare wetland, the area was expanded in 2017 to more than 32 hectares. The protection aims to preserve transition mires, floating bogs, and alder carr forests, as well as the habitat of threatened species such as the marsh orchid and rare water beetles. At the southern end of the reserve, a natural sledding run leads down the Teltow slope into the lowland.
