The distribution and abundance of cheatgrass, an invasive annual grass native to Eurasia, has increased substantially across the Intermountain West, including the Great Basin. Cheatgrass is highly flammable, and as it has expanded, the extent and frequency of fire in the Great Basin has increased by as much as 200%. These changes in fire regimes are associated with loss of the native sagebrush, grasses, and herbaceous flowering plants that provide habitat for many native animals, including Greater Sage-Grouse. Changes in vegetation and fire management have been suggested with the intent of conserving Greater Sage-Grouse. However, the potential responses of other sensitive-status birds to these changes in management...

Invasive species establish outside of their native range, spread, and negatively impact ecosystems and economies. As temperatures rise, many invasive plants can spread into regions that were previously too cold for their survival. For example, kudzu, ‘the vine that ate the south’, was previously limited to mid-Atlantic states, but has recently started spreading in New Jersey and is expected to become invasive farther north. While scientists know of many of the invasive species expanding into the northeastern U.S., they do not know where those species are likely to become abundant and how they will impact vulnerable native ecosystems due to climate change. There are also currently no strategies to manage emerging...

States in the North Central (NC) region have already been invaded by grass speciescapable of altering fire regimes and creating self-perpetuating 'grass-fire cycles'. Under climatechange, these grasses may interact with drought and fire to burn more and exclude native species. Managers can plan for these interactions and create collaborative communities to address thesecomplex challenges.

Covering 120 million acres across 14 western states and 3 Canadian provinces, sagebrush provides critical habitat for species such as pronghorn, mule deer, and sage-grouse – a species of conservation concern. The future of these and other species is closely tied to the future of sagebrush. Yet this important ecosystem has already been affected by fire, invasive species, land use conversion, and now, climate change. In the western U.S., temperatures are rising and precipitation patterns are changing. However, there is currently a limited ability to anticipate the impacts of climate change on sagebrush. Current methods suffer from a range of weakness that limits the reliability of results. In fact, the current uncertainty...
