This type of marsh vegetation is characterized by the tall tussocks of Carex appropinquata, which are accompanied by other tall sedges such as C. acutiformis. C. diandra and C. rostrata. It occupies peaty soils in mesotrophic littoral zones of fishponds, drainage ditches and depressions in mire complexes. The water regime is rather stable with water table near the soil surface. It is a rare vegetation type, occurring at only a few sites in the Czech Republic.
