British NVC community M22
NVC community M22 is one of the mire communities in the British National Vegetation Classification system, characterised by a sward of blunt-flowered rush with other rushes, grasses, sedges and wetland plants, in calcareous wet meadows. It is a form of pasture found around springs, flushes and in river valley wetlands, and it is one of three rush pasture communities in the NVC. It was once quite widespread in the English lowlands but is now rare and localised.
