State and transition models for rangelands.
3. The impact of the state and transition model on grazing lands research, management and extension: A review


Queensland Department of Primary Industries, Emerald, Queensland


The ability of the state and transition (S&T) model to improve the understanding of vegetation change in grazing lands is reviewed. The S&T model has been used as an additional research tool to collate previous knowledge into an improved format, to focus new research into key areas and to provide an improved perspective for ecological principles. By identifying the different states in a grazed vegetation and factors that cause transition between states, the understanding of vegetation change is enhanced and a framework is established in which relevant management manipulations can be planned. Recognition of the strengths and limitations of the S&T model is required if benefit to grazing land management is to occur.
