Effects of Cheatgrass Control on Wyoming Big Sagebrush in Southeastern Utah
… ranges in southeastern Utah dominated by Wyoming big sagebrush (Artemisia tridentata var. wyomingensis [Beetle and A. Young] Welsh) have developed dense cheatgrass (Bromus tectorum L.) understories. These communities are currently characterized by predominately mature to decadent stands of …

Vegetation response of a Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) community to 6 mechanical treatments in Rich County, Utah
In recent years, the importance of sagebrush to shrub-steppe ecosystems and associated plant and animal species has been recognized. The historical removal of herbaceous species by excessive and uncontrolled livestock grazing on many of our sagebrush ecosystems has resulted in a stagnant state …

Climatic influences on sagebrush establishment in Arid Rangelands: Applications for rangeland rehabilitation.
Sagebrush-dominated ecosystems are threatened by altered fire regimes, invasive species, infrastructure development, conversion to cropland, and encroachment by woody species. The economic and ecological significance of sagebrush makes it very important to develop successful strategies for …

Diet and Nutrition of the Pronghorn Antelope
… plants species. Major forage plants were big sagebrush (Artemisia tridentate), silver sage (A. cana), yellow sweet clover (Meliotus officinalis), gold aster (Chrysopsis villosa), and blue grama (Bouteloua gracilis). Cultivated small grain crops were not a major food source of pronghorn. …

Interactions between Bromus tectorum, grasshoppers, and native plants in sagebrush steppe communities
… As a result of this and other disturbances, sagebrush shrubland is among North America's most imperiled ecosystems. Restoration of B. tectorum-infested areas has often been unsuccessful, and there is a need to understand the factors limiting revegetation success. There is evidence that B. …

Effects of Moisture on Combustion Characteristics of Live California Chaparral and Utah Foliage
… and four from Utah (canyon maple, gambel oak, big sagebrush, and Utah juniper). Individual leaves were observed as they were exposed to hot gases from a flat flame burner. The broadleaf species from both California and Utah had noticeable surface changes during the ignition process. All fresh …

Sagebrush Ecosystem Characterization, Monitoring, and Forecasting with Remote Sensing: Quantifying Future Climate and Wildlife Habitat Change
<p>Sagebrush (<em>Artemisia spp.</em>) ecosystems constitute the largest single North American shrub ecosystem and provide vital ecological, hydrological, biological, agricultural, and recreational ecosystem services. Disturbances continue to alter this ecosystem, with climate change possibly …

SAGE-GROUSE AND THE HUMAN FOOTPRINT: IMPLICATIONS FOR CONSERVATION OF SMALL AND DECLINING POPULATIONS
… (15-56%), and overall shrub cover instead of sagebrush cover, was a better predictor of nest-site selection. Plains silver sagebrush (Artemesia cana cana) made up half of total shrub cover (7.1%) at nest sites, suggesting that other shrubs compensate for lower sagebrush densities in the MRB. …
