Oenanthetum aquaticae

This association includes stands of Oenanthe aquatica, a large umbellifer with hollow stems. It occurs mainly in fishponds and still water bodies in river floodplains, especially on sites with an exposed bottom or sites flooded by shallow water (up to 5 cm). However, it can also grow in greater depths of up to 1 m. This association has benefited from fishpond eutrophication. It is common in fishpond basins and river floodplains in lowlands and colline areas, but it also occurs at some sites in submontane areas.
