Name: Cardaria draba - Centaurea spp. - Lepidium latifolium Ruderal Perennial Forb Alliance
Reference: NatureServe Biotics 2019
Description: This interior western U.S. ruderal perennial herbaceous alliance is strongly dominated (&gt;90% relative canopy cover) by invasive, exotic perennial forbs such as <i>Acroptilon repens, Cardaria draba, Centaurea calcitrapa, Centaurea diffusa, Centaurea iberica, Centaurea stoebe ssp. micranthos, Centaurea virgata, Euphorbia esula, Hypericum perforatum, Lepidium latifolium, Linaria dalmatica, Linaria vulgaris, Peganum harmala</i>, or a mixture of other exotic perennial forbs. Stands occur in disturbed dry to mesic basins, alluvial fans, and foothills at elevations up to 2200 m throughout the cool, semi-arid intermountain western U.S. region. It is an early-successional type that may occur in areas disturbed by fire, grazing or mining.
