Sage-grouse & Sagebrush Ecosystem


Human actions and natural processes affect the sagebrush ecosystem through a variety of mechanisms. Understanding the influence of these factors on sage-grouse, other sagebrush associated species, and sagebrush ecosystem condition can help inform development of measures to minimize impacts to these resources and communities that depend on them. USGS scientists are addressing many of the important stressors in this ecosystem including the influence of surface disturbance and the subsequent removal of sagebrush habitat, expansion of conifer trees into sagebrush shrublands, spread of invasive species such as cheatgrass, rangeland fire, and livestock grazing.
