This association is dominated by Potamogeton pectinatus, a submerged macrophyte with a variable growth form, which depends on the habitat. It occurs in eutrophic and hypertrophic water, often with high turbidity, and on some sites with a high salt concentration. The habitats include mainly fishponds and middle and lower river courses, and less frequently fish storage ponds, alluvial pools, channels and flooded sand pits. Water depth is usually between 30 and 100 cm, but it can be as low as 5 cm. Historically this vegetation type was probably rare, but it expanded due to intensification of fishpond management and eutrophication in the second half of the 20th century. It is common in lowland and colline areas of the Czech Republic, but records are probably missing from many areas where it occurs.
