NVC community CG3 (Bromus erectus grassland) is one of the calcicolous grassland communities in the British National Vegetation Classification system. This article gives an overview of the Calcicolous grassland communities in the British National Vegetation Classification system For the US national vegetation classification see United States National Vegetation Classification Standard. For the US national vegetation classification see United States National Vegetation Classification Standard. It is one of four communities of rank, tussocky grassland associated with low levels of grazing, within the lowland calcicolous grassland group.
