These are highly productive meadows dominated by Alopecurus pratensis that mainly occur in the floodplains of large lowland rivers as well as in broad floodplains of smaller streams at higher altitudes. Unlike the physiognomically similar stands with sown Alopecurus pratensis, they are confined to regularly flooded sites and contain several moisture-demanding species. The water table does not recede in summer to the same extent as in other associations. Accordingly, the soils do not dry out for longer periods and most species with pronounced continental distribution ranges are missing.
