British NVC community OV15
From Wikipedia, the free encyclopedia
British NVC community OV15 (Anagallis arvensis - Veronica persica community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of two arable weed communities of light lime-rich soils.
It is a widely distributed community in south-east England, but is found only locally, its distribution being restricted to areas of suitable soils.
There are four subcommunities.
The following constant species are found in this community:
- Scarlet pimpernel (Anagallis arvensis)
- Black-bindweed (Fallopia convolvulus)
- Knotgrass (Polygonum aviculare)
- Common field-speedwell (Veronica persica)
Two rare species are associated with the community:
- Ground-pine (Ajuga chamaepitys)
- Shepherd's-needle (Scandix pecten-veneris)
A distinctive feature of most occurrences of this community is the presence, in mid- to late-summer, of Kickxia, represented by one or both of K. spuria and K. elatine, and Euphorbia exigua.
