Description

Ephemeral communities of tall short-lived plants growing on nutrient-rich muds (deposited in their margins by rivers draining a large, densely populated by humans or intensively cultivated watershed) emerged during summertime low water They may be eventually outcompeted by Q51x, unless thr frequency of sufficiently violent floods becomes too high. EUNIS stopping at level III, a regional level IV was created for the sake of consistency.
