Vegetation changes in managed ecosystems are the result of complex interactions among the manipulations imposed by the manager and the biotic and abiotic factors of the environment. These factors operate by altering the fineness of the environmental sieves at different stages in the life cycles of the constituent species. The factors have been identified in the Jenny equation and the interactions summarised in a way that can be useful to the land manager in the State and Transition model. Data are presented illustrating how these concepts can be applied to the problem of the maintenance of woodland eucalypts in grazed pastures on the Northern Tablelands of New South Wales.
