This vegetation type is dominated by Glyceria fluitans, a wetland grass occurring in small fishponds, fish storage ponds, along brooks and ditches, in puddles on forest roads, oxbows and alluvial pools, periodically inundated depressions on arable land, and in shallow, lentic sections of rivers. Glyceria fluitans-dominated stands usually occur in wet or shallowly flooded sites, but they can also develop in deep water, where they are submerged or floating on the water surface, and rooted on the bottom or on the bank. The nutrient status of the water ranges from oligotrophic to eutrophic. In the Czech Republic this vegetation type is most common in cool and precipitation-rich colline and submontane areas with acidic bedrock.
