British NVC community OV23 (Lolium perenne - Dactylis glomerata 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 occurs widely throughout lowland Britain.
There are four subcommunities.
The following constant species are found in this community:
There are no rare species associated with the community.
This community occurs widely throughout lowland Britain. It is often found on verges, recreational areas and waste ground that have been re-seeded but only occasionally mown and usually forms a mosaic with other communities, the degree of trampling and disturbance being major determinants in the occurrence of one community or another.
There are four 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 MG1, Arrhenatherum elatius grassland, is one of the mesotrophic grassland communities in the British National Vegetation Classification system. This type of plant community was named in 1919 as Arrhenatheretum elatiorisBr.-Bl.. It is a very widespread community throughout the British lowlands of England, Wales and southern and eastern Scotland.
British NVC community MG11 is one of the mesotrophic grassland communities in the British National Vegetation Classification system. It is one of three types of mesotrophic grassland classified as grass-dominated inundation communities.
NVC community CG2 is one of the calcicolous grassland communities in the British National Vegetation Classification system. It is one of three short-sward communities associated with heavy grazing, within the lowland calcicolous grassland group, and is regarded as "typical" chalk grassland.
British NVC community MG5 is one of the mesotrophic grassland communities in the British National Vegetation Classification system. It is one of four such communities associated with well-drained permanent pastures and meadows.
British NVC community MG6 is one of the mesotrophic grassland communities in the British National Vegetation Classification system. It is one of four such communities associated with well-drained permanent pastures and meadows.
British NVC community MG3 is one of the mesotrophic grassland communities in the British National Vegetation Classification system. It is one of four such communities associated with well-drained permanent pastures and meadows.
British NVC community MG4 is one of the mesotrophic grassland communities in the British National Vegetation Classification system. It is one of four such communities associated with well-drained permanent pastures and meadows.
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 MC4 is one of the maritime cliff communities in the British National Vegetation Classification system. It is one of five communities categorised as maritime cliff crevice and ledge communities.
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.
NVC community CG6 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.
NVC community CG1 is one of the calcicolous grassland communities in the British National Vegetation Classification system. It is one of three short-sward communities associated with heavy grazing, within the lowland calcicolous grassland group, and is regarded as the south-west coastal counterpart of "typical" chalk grassland.
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 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.
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 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.
British NVC community OV26 is one of the open habitat communities in the British National Vegetation Classification system. It is one of four tall-herb weed communities.
