Abstract

A general state and transition model is described for the herbaceous component of the vegetation in the northern speargrass zone (Gladstone to the base of Cape York Peninsula). The states have been identified and named by the dominant vegetation component e.g. perennial tussock grasses, Indian couch grass, and the factors likely to contribute to the transitions between states are listed e.g. utilisation rate, fire, seed source.
