Short summary
Arid ecosystem health is a complex interaction between vegetation and climate. Coupled with impacts from grazing, it can result in quick changes in vegetation cover. We present a wind erosion and vegetation health model with active grazers over 100-year tests to find the limits of arid environments for different levels of vegetation, rainfall, wind speed, and grazing. The model shows the resilience of grass landscapes to grazing and its role as an improved tool for managing arid landscapes.
