British NVC community OV18 (Polygonum aviculare - Chamomilla suavolens community) 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.
This community is found throughout the lowlands and upland fringes of Britain on loamy and sandy soils that are disturbed or moderately trampled.
There are two subcommunities.
The following constant species are found in this community:
There are no rare species associated with the community.
This ephemeral community is widely distributed throughout the lowlands and upland fringes of Britain. It occurs on loamy and sandy soils that are subjected to disturbance and moderate trampling, such as around tracks and gateways on agricultural land, on wasteland, and in recreational areas. Where trampling is heavier, it is replaced by the Poa annua - Plantago major community, OV21.
There are two subcommunities:
This article gives an overview of the plant communities formed by vegetation of open habitats in the British National Vegetation Classification system.
British NVC community OV4 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 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.
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 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 OV6 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 OV10 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 OV11 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 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 OV13 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 OV14 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 OV19 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.
British NVC community OV21 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.
British NVC community OV22 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.
British NVC community OV23 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.
British NVC community OV24 is one of the open habitat communities in the British National Vegetation Classification system. It is one of four tall-herb weed communities.
British NVC community OV25 is one of the open habitat communities in the British National Vegetation Classification system. It is one of four tall-herb weed communities.
