This study compared spring and fall prescribed fires at three sites (native-dominated, Bromus tectorum-dominated, and Juniperus occidentalis-dominated). There were higher plant survival rates following fall fires and native-dominated sites than in spring burns or where exotics dominated. These results show that burn season and prefire condition are important considerations when evaluating management alternatives in Artemisia tridentata ssp. vaseyana ecosystems.
View guide.
This guide, which includes the basic biology, life stages and habitat needs, habitat components, sagebrush monitoring, conservation planning in Wyoming, and predator impact, is intended to enhance understanding of sage-grouse conservation in Wyoming. Greater sage-grouse conservation, put simply, is understanding the needs of the sage-grouse for each life stage,knowing the life stage you provide habitat for, knowing what threats exist on the land, and implementing actions on the land to minimize or reduce the threats.

This study used a genecological approach to explore genetic variation for survival in Artemisia tridentata (big sagebrush). It found evidence of adaptive genetic variation for survival. Plants from areas with the coldest winters had the highest levels of survival, while populations from warmer and drier sites had the lowest levels of survival. Survival was lowest, 36%, in the garden that was prone to the lowest minimum temperatures. These results suggest the importance of climatic driven genetic differences and their effect on survival. Understanding how genetic variation is arrayed across the landscape, and its association with climate can greatly enhance the success of restoration and conservation.

This handbook walks managers and practitioners through a number of site-specific decisions managers face before selecting the appropriate type of restoration. This site-level decision tool for restoration of sagebrush steppe ecosystems is organized in nine steps.
- Step 1 describes the process of defining site-level restoration objectives.
- Step 2 describes the ecological site characteristics of the restoration site. This covers soil chemistry and texture, soil moisture and temperature regimes, and the vegetation communities the site is capable of supporting.
- Step 3 compares the current vegetation to the plant communities associated with the site State and Transition models.
- Step 4 takes the manager through the process of current land uses and past disturbances that may influence restoration success.
- Step 5 is a brief discussion of how weather before and after treatments may impact restoration success.
- Step 6 addresses restoration treatment types and their potential positive and negative impacts on the ecosystem and on habitats, especially for greater sage-grouse. We discuss when passive restoration options may be sufficient and when active restoration may be necessary to achieve restoration objectives.
- Step 7 addresses decisions regarding post-restoration livestock grazing management.
- Step 8 addresses monitoring of the restoration; we discuss important aspects associated with implementation monitoring as well as effectiveness monitoring.
- Step 9 takes the information learned from monitoring to determine how restoration actions in the future might be adapted to improve restoration success.

Collectively, the data analyzed in this study demonstrate that good condition ungrazed Wyoming big sagebrush plant communities exhibited resilience following fire and maintained a native-dominated mosaic of shrubs, bunchgrasses, and forbs. Further, unburned control plots were dominated by woody vegetation and exhibited losses in herbaceous understory, possibly indicating that they are outside of their natural fire return interval.

This study provides quantitative evidence linking long-term declines of sage-grouse to chronic effects of wildfire. Projected declines may be slowed or halted by targeting fire suppression in remaining areas of intact sagebrush with high densities of breeding sage-grouse.
