British NVC community OV13

British NVC community OV13 (Stellaria media - Capsella bursa-pastoris community) 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.

It is a widespread community, in which four subcommunities are recognised.

Community composition

The following constant species are found in this community:

Shepherd's-purse (Capsella bursa-pastoris)
Fat-hen (Chenopodium album)
Knotgrass (Polygonum aviculare)
Groundsel (Senecio vulgaris)
Common chickweed (Stellaria media)

There is one rare species associated with the community:

Tall ramping-fumitory (Fumaria bastardii)

Subcommunities

Four subcommunities are recognised:

the typical subcommunity
the Matricaria perforata - Poa annua subcommunity
the Fumaria officinalis - Euphorbia helioscopa subcommunity
the Urtica dioica - Galium aparane subcommunity

Distribution

This community is widespread throughout lowland Britain. It is commonly found as a weed vegetation among root and vegetable crops, but is also found among cereal crops and on disturbed ground. Because many of the constituent species are tolerant of commonly used herbicides, it is one of the commonest weed assemblages in intensively farms and market gardens.
