Reference: EcoArt 2002
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.
