Herbfields are plant communities dominated by herbaceous plants, especially forbs and grasses. They are found where climatic conditions do not allow large woody plants to grow, such as in subantarctic and alpine tundra environments. Herbfield is defined in New South Wales (Australia) government legislation as native vegetation that predominantly does not contain an over-storey or a mid-storey and where ground cover is dominated by non-grass species.〔NSW Dept of Environment, Climate Change and Water.〕 The New Zealand Department of Conservation has described herbfield vegetation as that in which the cover of herbs in the canopy is 20–100%, and in which herb cover is greater than that of any other growth form, or of bare ground.〔Lux et al. (2009).〕 Various kinds of herbfield include: * Tall alpine herbfield * Short alpine herbfield * Tussock herbfield * Wet herbfield * Aquatic herbfield ==References== 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「Herbfield」の詳細全文を読む スポンサード リンク
