This marsh type is dominated by Glyceria maxima, a 1–2 m tall grass. It occurs in shallow, usually 0–30 cm deep water in eutrophic to hypertrophic wetlands, such as fishponds, oxbows, alluvial pools, wet depressions in alluvial meadows, ditches, channels and slow streams. It tolerates significant fluctuations of water table, but is sensitive to deep flooding in the growing season. This association occurs in advanced stages of wetland succession, usually following the stands of Phragmites australis or Typha spp., and preceding the advent of sedge marshes. It occurs in lowland and colline areas across the Czech Republic, and locally also in submontane areas.
