Bromus hordeaceus (soft brome) is an annual grass (family Poaceae) distributed at low elevation areas in California, especially in disturbed and open areas. Bromus hordeaceus out competes native grasses and is commonly eaten by range animals, although its forage value is very low. It can invade soils with low fertility, such as the serpentine soils that are home to rare plant species.Cal-IPC Rating: Limited
