This paper reviews those aspects of the scientific literature that bear on the management of the native saltbush, grassland, belah and bluebush communities of south-west New South Wales. In includes information on the structure, vegetation change, erosion, animal production and management, and includes tables of the characteristics of the major plant species. Grazing can induce major vegetation changes in saltbush areas, but only relatively minor changes in the more stable communities, such as belah. Erosion hazards are severe in the bluebush communities, although they are generally stable at present. Animal production is closely related to the winter incidence of rainfall, when both sheep and cattle concentrate their grazing on annual plants. In summer saltbushes, bluebushes and copper burrs become the main constituents and diet quality is adequate for maintenance. Research suggests that controlled continuous grazing is the best option for both production and pasture management in these communities. The future use of controlled burning to reduce unpalatable shrubs in belah communities is indicated. |
