Wet grassland is a habitat that forms on flat or sloping ground on wet or waterlogged soils that are poorly drained or subject to seasonal or periodic flooding. Wet grassland often contains abundant rushes and grasses such as Yorkshire Fog, Creeping Bent and Marsh Foxtail.
Wet grassland is distinguished from marsh when the grass, sedge and rush component is greater than 50% of the vegetation cover.
This habitat was formerly widespread in lowland meadows that flooded in the winter. River drainage and embankment has severely disrupted and in many cases eliminated the wetland nature of floodplains and this has led to the disappearance of wet grassland meadows.
