This article gives an overview of the plant communities formed by vegetation of open habitats 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, strandline and sand-dune communities, salt-marsh 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) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vegetation of open habitats in the British National Vegetation Classification system」の詳細全文を読む スポンサード リンク
