A genecological approach was used to explore genetic variation for survival in Artemisia tridentata (big sagebrush). Artemisia tridentata is a widespread and foundational shrub species in western North America. This species has become extremely fragmented, to the detriment of dependent wildlife, and efforts to restore it are now a land manage-ment priority. Common- garden experiments were established at three sites with seed-lings from 55 source- populations. Populations included each of the three predominant subspecies, and cytotype variations. Survival was monitored for 5 years to assess dif-ferences in survival between gardens and populations. We found evidence of adap-tive genetic variation for survival. Survival...

The sagebrush steppe is a patchwork of species and subspecies occupying distinctenvironmental niches across the intermountain regions of western North America. These ecosystems facedegradation from disturbances and exotic weeds. Using sagebrush seed that is matched to its appropriateniche is a critical component to successful restoration, improving habitat for the threatened greater sage-grouse and other species. The need for restoration is greatest in basin habitats composed of two subspecies:diploid basin big sagebrush (A. tridentatasubsp.tridentata) and tetraploid Wyoming big sagebrush (subsp.wyomingensis). In this study we assess seed weights across five subspecies-cytotype groups of bigsagebrush and examine...
