Popis:	This review deals with the role of legumes in native and low‐input perennial pastures in temperate Australia. It draws on lessons learnt from the problems associated with legume dominance and proposes development and management strategies to ensure a sustainable role for legumes in pasture systems in the future. The low‐input syndrome is defined in geographical and management terms, and the historical role of legumes in pasture development/decline in the higher‐rainfall zone of eastern Australia is summarised. In general, while the loss of perennial native grasses is often attributed to the introduction of a vigorous legume, other factors such as invasion of annual (Mediterranean) grasses and broad‐leaf species, and the lack of appropriate grazing strategies must also share a significant responsibility for the decline in these species. The proposed characteristics of a stable, low‐input pasture system are: a diverse range of species; a high degree of botanical stability; an economic level of prod...
