Cheatgrass is found in all fifty states and dominates 100 million acres in the intermountain west. It occurs in wildlands most commonly in sagebrush/bunchgrass communities, although its distribution extends to higher-elevation juniper, pinyon-juniper, and pine woodlands. Widespread in sagebrush steppe communities, low-elevation salt-desert shrub communities, higher-elevation juniper, pine woodlands, coniferous forest zone of the Rocky Mountains, bunchgrass zone, ponderosa pine, sagebrush rangelands, desert-facing slopes of Sierra Nevada, interior Douglas-Fir communities, abandoned fields, riparian vegetation, riparian meadows, grasslands, abandoned cropland, roadsides, and "waste places". It changes fire cycle frequency from once every 60-100 years to once every 3-5 years, causing perennials to give way to an annual community dominated by cheatgrass. It depletes soil moisture which may negatively affect the root growth of native species. It can form monospecific stands. Cheatgrass is used as green food for livestock and some wild animals also use it but its production is highly undependable because its based on precipitation plus the green period is much shorter (NatureServe, 2007).
