Abstract:
Maintaining plant diversity under livestock grazing and long droughts is a challenge in arid rangelands. Maintaining the plant diversity can and has been done through rotation grazing and movement of cattle from pasture to pasture at a trigger point. The trigger point is utilization levels of between 40% and 50% of annual growth of forage plants.
