British NVC community CG2

British NVC community CG2

__NOTOC__

NVC community CG2 ("Festuca ovina - Avenula pratensis" 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 "typical" chalk grassland.

It is a comparatively widely distributed community. There are four subcommunities.

ubcommunities

There are four subcommunities, one of which is subdivided into three variants:
* the "Cirsium acaule - Asperula cynanchica" subcommunity, subdivided into:
** a typical variant
** a "Filipendula vulgaris - Helinathemum nummularium" variant
** a "Pseudoscleropodium purum - Prunella vulgaris" variant
