Two states of herbaceous vegetation, one dominated by palatable perennial grasses (SI) and the second by less palatable perennial grasses and annual species (SID, were subjected to different levels of utilisation by cattle at two sites in the tallgrass region of northern Queensland. Trends in basal area and percentage of perennial grasses were not linear: SI pastures were initially resistant to change in response to high levels of utilisation while SII pastures started to recover quickly once utilisation was relaxed or removed. A non-linear model of perennial grass change is described.
