A whole -paddock study of the variation in the grazing intensity of saltbush (Atriplex vesicaria) by sheep and its effects on the plants' population dynamics is being carried out in South Australia. The study is concerned with the future productivity and management of the chenopod shrublands, with the aim of maintaining perennial shrub densities. This paper summarises progress for the first 2.5 years of the study. Data is still being collected and analysed. Indications are that a more flexible stocking system is needed to maintain the condition of these pastures.
