Name:
Artemisia spp. - Mixed Shrub Ruderal Understory Shrubland Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance covers those native shrublands that have had their herbaceous component completely replaced by non-native, invasive herbaceous species. Overstory shrubs include <i>Artemisia tridentata</i> (all subspecies), <i>Artemisia tridentata ssp. spiciformis, Artemisia arbuscula</i>, and <i>Artemisia tripartita</i>. Understory dominant herbaceous non-native species include graminoids <i>Bromus tectorum, Agropyron cristatum, Agrostis stolonifera, Taeniatherum caput-medusae, Poa bulbosa, Bromus diandrus</i>, and forbs <i>Sisymbrium altissimum, Descurainia pinnata, Onopordum acanthium, Cirsium</i> spp., <i>Centaurea</i> spp., <i>Lepidium</i> spp., and many others. Native herbaceous species may be present, but occur in very low abundance, less than 10% relative cover of all herbaceous cover. These stands occur in all areas where native sagebrush stands occur throughout the western U.S.
