Interpretive Summary: Drought is an inherent property of rangeland ecosystems and its many impacts on the structure and function of rangeland ecosystems, and subsequently on the economic well-being of rangeland based enterprises, is immense. To minimize these impacts, it is imperative that management personnel respond to drought in a proactive rather than reactive manner. Research conducted near Miles City, MT has shown that on average 90% (SD = 12) of annual perennial grass production is completed by July 1. These findings provide rangeland managers ample opportunity to make timely, proactive, mid-year stocking rate adjustments that will lesson ecological and economic risks arising from late season forage demand/availability imbalances.
