Although rangelands are one of the most important ecological-economic systems on our planet, researchers thus far have paid scant attention to the study of range management from a theoretical perspective. As such, this book provides a systematic approach to the theoretical study of range management under uncertainty. In particular, the book demonstrates how the theory of stochastic processes and the techniques of stochastic modelling can be used to construct and analyse theoretical models of jointly determined rangelands and thereby shed light on the task of range management. Because specialised grazing systems involving the rotation of animals between pastures have been a major focus of range managers since the 1950s, this book pays considerable attention to questions that arise when specialised grazing systems such as short duration grazing are used to manage rangelands. Specific issues that are analysed in this book include the optimal number of paddocks in short duration grazing, the steady state distribution of animals in short duration grazing. Also, the effect of potential irreversibilities, the choice between the stocking rate and time, herding in ranch operations, and the role of time in range management, is discussed.
