British NVC community OV4 (Chrysanthemum segetum - Spergula arvensis community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of six arable weed and track-side communities of light, less-fertile acid soils.
It is widely distributed, and there are two subcommunities.
The following constant species are found in this community:
No rare species are associated with the community.
This is a widely distributed community, most commonly found in western Britain.
The two subcommunities are:
British NVC community OV5 is an open habitat community in the British National Vegetation Classification system. It is one of six arable weed and track-side communities of light, less-fertile acid soils.
NVC community SD18 is one of the 16 sand-dune communities in the British National Vegetation Classification system.
NVC community SD1 is the only shingle community in the British National Vegetation Classification system.
British NVC community OV42 is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities of crevice, scree and spoil vegetation.
British NVC community OV41 is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities of crevice, scree and spoil vegetation.
British NVC community OV39 is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities of crevice, scree and spoil vegetation.
British NVC community OV20 is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities characteristic of gateways, tracksides and courtyards.
NVC community CG3 is one of the calcicolous grassland communities in the British National Vegetation Classification system. It is one of four communities of rank, tussocky grassland associated with low levels of grazing, within the lowland calcicolous grassland group.
British NVC community OV9 is one of the open habitat communities in the British National Vegetation Classification system. It is one of eight arable weed and wasteland communities of fertile loams and clays.
British NVC community OV1 is one of the open habitat communities in the British National Vegetation Classification system. It is one of six arable weed and track-side communities of light, less-fertile acid soils.
British NVC community OV2 is one of the open habitat communities in the British National Vegetation Classification system. It is one of six arable weed and track-side communities of light, less-fertile acid soils.
British NVC community OV3 is one of the open habitat communities in the British National Vegetation Classification system. It is one of six arable weed and track-side communities of light, less-fertile acid soils.

British NVC community OV12 is one of the open habitat communities in the British National Vegetation Classification system. It is one of eight arable weed and wasteland communities of fertile loams and clays.
British NVC community OV15 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.
British NVC community OV17 is one of the open habitat communities in the British National Vegetation Classification system. Although classed with communities OV15 and OV16 as an arable weed community of light lime-rich soils, it also shares many features with the communities classed as arable weed and wasteland communities of fertile loams and clays.
British NVC community OV18 is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities characteristic of gateways, tracksides and courtyards.
