It is often difficult to determine whether change in rangeland conditions results from grazing pressure or from climatic or seasonal influences. A monitoring approach using remote sensing techniques and an extension of the gradient grazing method appears to offer some advantages over traditional intensive on-ground measurements. Application of the approach to the Marla-Oodnadatta Soil Conservation District in South Australia, indicated that satellite technology offers extension tools which can supplement and guide on-ground investigations and aid the understanding of spatial patterns in rangeland landscapes (A).
