All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Historic and repetitious spring grazing by livestock, combined with altered fire regimes, has increased the density and abundance of big sagebrush and reduced the frequency of perennial grasses and forbs on many western landscapes. Periodic disturbance is critical for maintaining and improving sagebrush ecosystems. Compared with traditional disturbances – chemical, mechanical, and fire – strategic grazing with livestock offers several benefits. They include creating locally adapted cattle that can rejuvenate sagebrush steppe, which reduces costs associated with mechanical and chemical rejuvenation treatments and feeding cattle during winter, the major cost of ranch operation.

I evaluated the practicality of strategically timed …
