Ever Graze-More livestock from perennials

The 550-800 mm temperate pasture regions of southern Australia maintain around 30 m sheep and 7 m beef cattle.However,many pastures are dominated by annuals due to a failure to use appropriate perennials for the environment or inadequate management of native or introduced perennials.The lack of perennials in these relatively high rainfall regions has lead to environmental challenges including dryland salinity,wind and water erosion due to low ground cover,and declining water quality and biodiversity.Climate predictions are for lower and more variable rainfall.Also,the profitability of many grazing farms is lower than annual cropping systems.
