Surface Disturbance

Conservation and restoration of the sagebrush ecosystem is a major challenge. There are numerous threats to the ecosystem including increasing risk of wildfire, invasion by exotic annual grasses, expansion of conifer trees, development for agricultural use and energy extraction, and many other natural and human caused disturbances. Restoration of sagebrush habitat following a disturbance is complicated by moisture availability and the length of time required for the vegetation community to recover. To meet this conservation challenge, it is critical that land management is guided by the best available science so that actions are effective and located in the places where they can have the best overall outcome.

Cheatgrass and Medusahead

Invasive annual grasses, such as cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae), are one of the most significant stressors to rangeland ecosystems in the western U.S. Their expansion and dominance across this area are the most damaging ecosystem agents on this iconic landscape.

Stressors to Greater Sage-Grouse

The Greater Sage-grouse is a small bird found only in the sagebrush steppe of the Great Basin. Invasions of non-native grasses, evolving wildfire patterns, grazing from livestock, and human land uses are changing this unique ecosystem. WERC’s Dr. Pete Coates studies sage-grouse populations to determine how these influences could affect the bird and other wildlife in the future.
