Common names: cheatgrass; downy brome
Bromus tectorum (downy brome, cheatgrass) is an annual grass (family Poaceae). It is the dominant grass on sagebrush (Artemisia species) rangelands on the Modoc Plateau in northeastern California and along the eastern Sierra Nevada to Owens Valley. This weed overcrowds native grasslands and croplands. Replacement of native grasses by cheatgrass increases the frequency and extent of wildfires.Cal-IPC Rating: High
