Great Basin sagebrush communities are experiencing widespread degradation due to the introduction of invasive annual weeds and disturbances that promote weed expansion, including inappropriate grazing and fire. Many sites previously occupied by diverse communities of perennial grasses, forbs, and shrubs have been reduced to depauperate sagebrush stands that readily become dominated by invasive annuals following fire. Post-fire seeding may be necessary to prevent these areas from converting to annual grasslands.

It is likely that increasing temperatures will stress native sagebrush steppe species in the lowest, hottest basins more than in cooler and wetter upland habitats. Second, the effect of climate change on cheatgrass and fire is critical but uncertain. Regional warming will increase the frequency of hot, dry conditions that promote fire, but droughts could dampen the fire cycle by limiting the production of fine fuels. Third, the adaptive capacity of sagebrush is unknown and research on the potential for sagebrush to adapt to climate change should be a high priority.

Big sagebrush cover decreased significantly in response to spring temperatures. On the other hand, cheatgrass cover and Sandberg’s bluegrass cover increased mostly in wetter years. Three other species analyzed, three-tip sagebrush, needle-and-thread grass and bluebunch wheatgrass, showed very weak responses to annual climate. This analysis shows that species commonly found together may differ in how they respond to annual climate variation. The weak response to annual climate variation we observed is in contrast to the strong sensitivity to climate predicted by species distribution models. Our analysis suggests that species’ responses to climate may require long-term changes in climate or may be driven by other indirect effects of climate, such as fire frequency.

The primary goal of this project was to assess the effect of climate change on carbon cycling in mature sagebrush ecosystems. We used initial soil characteristics and carbon values for three location and modeled future climate at those locations for four different climate scenarios. We found that mature sagebrush ecosystems continued to act as carbon sinks into the future under all different climate change scenarios. The magnitude of carbon storage differed depending on initial conditions and soil characteristics at each site. Climate change may affect the potential for sequestration by increasing carbon loss through respiration, but we found that increased losses were offset by increased gains through greater primary production.
