This association includes monodominant stands of Zannichellia palustris or mixed stands of this species with Potamogeton pectinatus and/or P. pusillus. All of these species have narrow, submerged leaves. They occur in eutrophic to hypertrophic, often turbid, shallow water, e.g. at fishpond margins, fish storage ponds, alluvial pools, flooded sand pits, rarely also in small streams with slowly running water. For long periods in summer they may survive in shallow (up to 1 cm deep) puddles. This association is common in warm areas of the Czech Republic.
