British NVC community CG7

Last updated

NVC community CG7 (Festuca ovina - Hieracium pilosella - Thymus praecox/pulegioides grassland) is one of the calcicolous grassland communities in the British National Vegetation Classification system. It is one of three short-sward communities associated with heavy grazing, within the lowland calcicolous grassland group, and is regarded as the eastern counterpart of "typical" chalk grassland (community CG2).

Distribution

This community is found scattered throughout chalk grassland sites in southern England, particularly in The Brecks on the Norfolk/Suffolk border, with outlying clusters in the Yorkshire Wolds (also on chalk), and on Carboniferous limestone in Derbyshire and Mendip Hills.
