Name: Artemisia cana (ssp. bolanderi, ssp. viscidula) Shrub Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This alliance occurs across the northern portions of the Great Basin in Oregon and Idaho, and into southwestern Montana, as well as the mountains of Nevada. Stands are found on inactive elevated stream and river terraces and on upland areas with sandy soils. This vegetation has a sparse shrub layer (<25%) composed primarily of the characteristic shrub Artemisia cana (ssp. bolanderi or ssp. viscidula), but Artemisia tridentata (usually ssp. vaseyana but occasionally ssp. tridentata) are common in some stands. The herbaceous layer is dominated by graminoids, generally with >20% cover, and often with more cover than the shrub layer. Important understory associates include Festuca idahoensis, Poa fendleriana ssp. fendleriana, Poa cusickii, Muhlenbergia richardsonis, Elymus caninus, Koeleria macrantha (= Koeleria nitida), Achnatherum occidentale, Carex praegracilis, and Elymus trachycaulus. Common exotic associates include Poa pratensis, Taraxacum officinale, and Agrostis stolonifera. Among the forbs that are typically found are Achillea millefolium, Symphyotrichum campestre var. bloomeri (= Aster campestris var. bloomeri), and Cirsium foliosum. The vegetation in the alliance includes non-wetland plant associations dominated by Artemisia cana ssp. bolanderi or Artemisia cana ssp. viscidula with typically less than 25% total shrub cover and an abundant herbaceous cover of medium stature.  Accession Code: VB.CC.22477.ARTEMISIACANASS Plot-observations of this Community Concept: 0
