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.
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. ==Subcommunities==
