Abstract

In the Western United States, cheatgrass (Bromus tectorum, introduced from Eurasia) is often considered to be an undesirable, invasive weed. When cheatgrass is introduced into an area, it can rapidly establish itself as the dominant species, inhibiting reestablishment of native plants, competing with important grain crops such as winter wheat, and increasing the frequency of fire.1,2,3 Over the last one-hundred years, cheatgrass has spread so rapidly that it is now a dominant grass in large areas of the United States.
