Abstract
<jats:p>Degradation in Australia's arid grazing lands can be a multi-faceted problem involving soil erosion, soil degradation and pasture species change which includes shrub invasion. Each can reduce grazing productivity and all three interact in space, and over time. An added complexity is that some forms of degradation may occur naturally but also are accelerated by poor grazing management. Surveys of degradation frequently rely on "point" survey techniques. Selection of these sample "points" can quite often ignore the linkages between key landscape components, e.g. the areas that shed soil, and those that accumulate soil. A regional or whole-landscape approac...
