Summary of Methods: Modeling paper investigating vegetation-regulated herbivore population dynamics in semi-arid grasslands. Irreversible vegetation change may occur for a larger set of soil and climatic conditions when herbivore numbers are independent of the vegetation (human controlled herbivory levels), as compared to systems where vegetation density determines herbivore population size. The analysis suggests that irreversible vegetation change is less likely to occur in systems with natural herbivore population dynamics than in systems where humans control herbivore density.
