This article gives an overview of the open habitat communities in the British National Vegetation Classification system.
Introduction
The open habitat communities of the NVC were described in Volume 5 of British Plant Communities, first published in 2000, along with the three groups of maritime communities (shingle, strand-line and sand-dune communities, saltmarsh communities and maritime cliff communities).
In total, 42 open habitat communities have been identified.
The open habitat communities consist of eight separate subgroups:
- six arable weed and trackside communities of light, less-fertile acid soils (OV1, OV2, OV3, OV4, OV5 and OV6)
- eight arable weed and wasteland communities of fertile loams and clays (OV7, OV8, OV9, OV10, OV11, OV12, OV13 and OV14)
- three arable weed communities of light, limey soils (OV15, OV16 and OV17)
- six gateway, trackside and courtyard communities (OV18, OV19, OV20, OV21, OV22 and OV23)
- four tall-herb weed communities (OV24, OV25, OV26 and OV27)
- five communities typical of periodically inundated habitats (OV28, OV29, OV30, OV32 and OV33)
- four dwarf-rush communities of ephemeral ponds (OV31, OV34, OV35 and OV36)
- six communities of crevice, scree and spoil vegetation (OV37, OV38, OV39, OV40, OV41 and OV42)
