This study explored how fire and various other natural events might
shape sagebrush ecosystems in eastern Oregon, USA, and whether those
events could affect fire rotation. Results suggested other disturbance
events were important in shaping all but the most productive sagebrush
communities and influenced fire rotation in drier sagebrush communities.
Insects and pronghorn browsing may have been as important as fire in shaping sagebrush-steppe landscapes with freezekill and snow mold locally important.
