This association includes emergent stands of Alisma gramineum in shallow water or submerged stands of this species in deep water. It occurs in small fishponds with fluctuating water table or fish storage ponds, which are built on mineral-rich or calcareous substrate or artificially limed. In the Czech Republic it occurs mainly in southern Bohemia, and also in the Labe area and southern Moravia.
