This brackish marsh is dominated by Bolboschoenus maritimus and some other species typical of saline soils. B. planiculmis also occurs in some stands, and occasionally it can become dominant. The association occurs in flooded depressions with brackish water in dry and warm areas, which dry out in summer. Less frequently it is found on the banks of shallow pools or around mineral springs. In the Czech Republic, it occurs at scattered sites in the lowland areas of western, northern and central Bohemia and southern Moravia.
