British NVC community OV21

British NVC community OV21 (Poa annua - Plantago major 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 ubiquitous in the lowlands and upland fringes of Britain wherever there is suitable habitat.

There are three subcommunities.

Community composition

The following constant species are found in this community:

Scented mayweed (Matricaria chamomilla)
Greater plantain (Plantago major)
Annual meadow-grass (Poa annua)

There are no rare species associated with the community.

Distribution

This community is ubiquitous in the lowlands and upland fringes of Britain. In rural areas it is found wherever farm tracks and gateways are heavily trampled; in urban areas it is a feature of recreational areas and wasteland, and can replace the Poa annua - Sagina procumbens community, OV18, in paved areas where crevices are large enough to permit the establishment of more robust vascular plants.

Subcommunities

There are three subcommunities:

the so-called typical subcommunity
the Lolium perenne subcommunity
the Polyonum aviculare - Ranunculus repens subcommunity
