This marsh type is dominated by the tall sedge Carex acuta. It occurs in shallow, eutrophic, or less frequently mesotrophic wetlands such as in the littoral zones of fishponds, water reservoirs, oxbows, alluvial pools, fish storage ponds, river banks, ditches and shallow depressions in meadows. Water depth is usually up to 10 cm, but the water table can drop below the soil surface for long periods in summer. The substrate is usually poorer in base cations than in other associations of the alliance Magno-Caricion gracilis. This vegetation type is common in lowlands and mid-altitudes of the Czech Republic; it also occurs in some submontane areas.
