On August 25, 2015 speaker Matt Germino presented on his work restoring sagebrush in the Great Basin. Shrubs are ecosystem foundation species in most of the Great Basin’s landscapes. Most of the species, including sagebrush, are poorly adapted to the changes in fire and invasive pressures that are compounded by climate change. This presentation gives an overview of challenges and opportunities regarding restoration of sagebrush and blackbrush, focusing on climate adaptation, selection of seeds and achieving seeding and planting success. Results from Great Basin LCC supported research on seed selection and planting techniques are presented.

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 spread and impacts of exotic species are unambiguous, global threats to many ecosystems. A prominent example is the suite of annual grasses in the Bromus genus (Bromus hereafter) that originate from Europe and Eurasia but have invaded or are invading large areas of the Western USA. This book brings a diverse, multidisciplinary group of authors together to synthesize current knowledge, research needs, and management implications for Bromus. Exotic plant invasions are multifaceted problems, and understanding and managing them requires the biological, ecological, sociological, and economic perspectives that are integrated in this book. Knowing how well information from one geographic or environmental setting can...

The INL Ecohydrology Experiment uses irrigation to simulate increased winter or summer precipitation. Treatments include a doubling of annual precipitation added in summer (four 50-mm events) or in winter (two 100-mm events added), and non-irrigated control plots. Standard USDA species abbreviations are used.
