Bromus marginatus
 Bromus maginatus is a species of grass known by the common name mountain brome. It is native to western North America and it is used widely for grazing animals and revegetating landscapes.This short-lived perennial grass forms a large shallow root network. The roots give it drought-tolerance and they persist in the soil long after the plant has died making it valuable for erosion control. The stems can usually reach one meter in height but are known to reach 1.5 meters.
