Environmental and economic pressures have resulted in previously cropped country being reestablished to native pastures in semi -arid areas of north -western NSW. Grazing systems have been considered an important factor in developing pasture viability. This is a study into the effects of short duration high intensity grazing under Holistic Resource Management (HRM)(Savory 1988) on a property in the Moree region of northern NSW. The short-term effects on aspects of the soil and native pasture will be measured over an autumn graze and rest period. The longer term effects will be assessed by a comparison with a continuously grazed native pasture. The main soil properties studied will include infiltration, porosity, bulk density, soil surface strength, soil moisture characteristics, water stable aggregates, carbon, nitrogen, phosphorus and several cations. Vegetation measurements will involve botanical composition, plant frequency and basal cover.
