Abstract

Bromus tectorum is an invasive species, commonly known as cheatgrass, that has caused major problems by disrupting the native plant ecosystem in the Intermountain West through a dramatically altered fire regime that has increased in frequency from 30-100 years to almost every 5 years (Brooks, 2002). Herbicides have been used as a form of control, but they are unsuccessful as they target only the growing plant, leaving seeds to carry over and germinate the next year, and are not selective, resulting in the death of many native plants. These problems present an urgent need to find alternative methods of control for B. tectorum.
