False-brome is a perennial bunch grass introduced as an experimental forage plant in the late 1930s. Since then, it has become widely distributed in northwestern Oregon and is found in limited areas of the Portland metro area. Efforts to understand false-brome spread and manage populations began in the late 1980s in the Corvallis area. It is known for creating dense carpets of vegetation, and spreads easily in a number of ways.
