Comparing natural area herbicides for residual weed control and native species tolerance
Downy brome (Bromus tectorum L.) is a competitive winter annual grass species, and is considered one of the most problematic invasive species on rangeland, open spaces and natural areas, and sites impacted by fire. Downy brome seeds germinate in the late summer or fall, overwintering until the seedlings begin rapidly growing in the spring, exploiting available water and nutrients before native grasses and forbs have emerged from dormancy. Invasive winter annual grasses, including downy brome, pose a major threat to native ecosystems by increasing fire frequency and intensity, degrading available ...
