Non-Native Brome Grasses in Montana (August 2021)

Prairie in the ‘Big Sky’ country at Fort Keogh Livestock and Range Research Laboratory in Miles City, Montana. Fort Keogh is used as working range, but is infested with two non-native invasive brome grasses, Bromus tectorum and Bromus arvensis (B. tectorum is the reddish-tinted grass in the picture). These non-native grasses cause major issues for ranchers in western United States, which is why they are important species of study. Photo credit: Morgan Frost.
