Name: Bromus tectorum - Taeniatherum caput-medusae Ruderal Annual Grassland Alliance
Reference: NatureServe Biotics 2019
Description: This interior western U.S. ruderal annual grassland alliance is strongly dominated (&gt;90% relative canopy cover) by invasive, exotic annual grass species such as <i>Bromus tectorum</i>, and less commonly <i>Bromus arvensis, Bromus hordeaceus, Bromus madritensis, Onopordum acanthium, Taeniatherum caput-medusae</i>, or a mixture of other exotic annual grasses. Cover of perennials is low (&lt;5% absolute cover). Stands occur in disturbed dry to mesic basins, alluvial fans, and foothills at elevations up to 2200 m throughout the cool, semi-arid interior western U.S. region. It is an early-successional type that may occur in areas disturbed by fire, grazing or mining.
