Devil fen

The Teufelsfenn is a boiler moor in the Grunewald in Berlin . It emerged from a silted-up lake, the water of which filled a dead ice hole at the end of the last ice age . The Teufelsfenn belongs together with the Postfenn to the 83  hectare “ Postfenn and Teufelsfenn nature reserve ”. The nature reserve also belongs to the Fauna-Flora-Habitat (FFH) Grunewald.

Due to the lowering of the groundwater , the Teufelsfenn had largely dried up in the past and typical bog species were displaced. Since the mid-1980s, the moor has been supplied with groundwater from the last active deep well of the 1969 shut-down waterworks at Teufelssee. Birch , poplar and bird cherry dominate a fenced-in area . However, there are also raised bog-specific plants such as B. Sundew before. The devil's fen is a habitat for various amphibian species . 35 breeding bird species were found in the area and in 2008 the occurrence of the marsh insect was detected for the first time .

To the northeast of the Teufelsfenn is the Teufelsberg .
