Geology
Glacifuvial, with intensive peat evolution The fen is separated from the Baltic Sea by a dune dike installed in 1963 which increased fresh water supply. The area had been intensively drained for grassland use since the 1970s with water levels down to 1.60 m below ground surface. Therefore, the peat in the upper soil horizons is weakly to strongly decomposed. Peat depths range between 1 and 3 mwith alternating layers of sandy sediments as a result of flooding events. For nature protection purposes first restoration measures were taken in 1992 by closing the main ditch (Schoenfeld-Bockholdt et al. 2005). Almost 20 years later, in 2009 a river bed sill was installed to permanently increase the water level to or above ground surface. Since then, the fen is permanently inundated with water levels up to 1.00 m above ground surface.
