Downy brome is an annual winter grass invading millions of acres of western rangelands and wildlands. It emerges early in the spring while native perennials are still dormant and creates dense mats of litter as it dies back at the end of its growing season. As a result, it can outcompete native vegetation and increase both the frequency and severity of wildfires.
