Grassland on wet or periodically wet sites with either high cover of sedges and/or rushes, or of herbs indicating wet conditions. Usually low-intensity mown or grazed grassland,

if fallow then wet meadow indicators still present. Characteristic phytosociological units included in meadow groups after von Drachenfels (2004) Mesic to moist PRT062607 variants of the Cynosurion or the Arrhenatherion
