British NVC community CG1
From Wikipedia, the free encyclopedia
NVC community CG1 (Festuca ovina - Carlina vulgaris 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 south-west coastal counterpart of "typical" chalk grassland (community CG2).
It is a comparatively localised community. There are six subcommunities.
