Extensive areas of Australia's semi -arid and arid grazing lands have been degraded. The present extent and seriousness of rangeland degradation is not precisely known because there is no simple, inexpensive and unequivocal way to define and measure it, but one recent estimate of the extent of the problem is that up to one third of all rangelands are affected (1). Some techniques for rehabilitating these degraded lands are available, for example, prescribed fire can be used to control dense shrubs thereby improving conditions for pasture production and in turn soil productive potential (2). However, there is no system for evaluating when and where restoration should take place and for choosing what is the most cost - effective treatment.
