Bromus species – such as cheatgrass – are exotic annual grasses that have become the dominant annual grasses in the western hemisphere. Their spread and impacts across the western United States continue despite the many attempts by land managers to control these species. A new book edited by scientists from the U.S. Geological Survey, U.S. Forest Service and Colorado State University answers critical research, planning, and management questions about these species. The book synthesizes available literature on the biology, ecology, sociology and economics of Bromus grasses to develop a more complete picture of the factors that influence their invasiveness, impacts, and management in the western United States. Lessons learned from this synthesis can be used to address impacts of species like cheatgrass on the sagebrush-steppe, a habitat that supports over 350 wildlife species, including greater sage-grouse. A joint USGS and U.S. Forest Service press release and a Colorado State University press release were both published on January 26, coinciding with the release of the eBook.
