The site DE-SfS is located in the center of the 111 ha large pre-alpine ombrotrophic bog Schechenfilz, close to the south bank of lake Starnberg in southern Germany. The central part of the bog, where the measurements take place, is still pristine and reaches a thickness of up to 6 m. The Schechenfilz is structured into open sedge areas, heather meadows and wooded areas. The study site is situated in the wooded area, dominated by a small bog-pine (Pinus mugo spp. Rotundata) that is adapted to wetlands.
