Abstract
This study describes techniques and models for identifying the distribution of grazing by domestic animals in large (> 100 km 2 ) rangeland paddocks in arid central Australia. It also examines the relationship between grazing distribution and the characteristics of the vegetation cover. Models of grazing distribution and resultant defoliation through time use the inverse Gaussian distribution function. Additional model components describe the effects of natural decline in cover over time and the effect of past grazing on the spatial distribution of palatable species. Models are calibrated using remotely sensed vegetation cover data derived from Landsat MSS and closely reflect observed animal distributions (...)
