Name: Artemisia cana (ssp. bolanderi, ssp. viscidula) - Artemisia tridentata ssp. vaseyana / Poa cusickii Shrub Grassland
Reference: NatureServe Biotics 2019
Description: This association is a tall shrubland occurring on moist playas or more commonly montane riparian benches (terraces) in the northern portions of the southern Blue Mountains, Great Basin, Modoc Plateau and eastern Cascades of Oregon, and potentially adjacent California and Nevada. Soils are generally deep alluvium with surface textures of fine sandy to silty clay loams. Water tables are high in May and June (within 60 cm of the surface), but drop to 120-160 cm between July and September. The shrub layer is codominated by both <i>Artemisia cana</i> and <i>Artemisia tridentata ssp. vaseyana</i>, although the type includes some pure stands of <i>Artemisia cana</i>. The characteristic feature of these benches is the dominance of <i>Poa cusickii</i> (formerly merged into <i>Poa fendleriana ssp. fendleriana</i>). This species dominates all plots, but other grasses and sedges can be found, including <i>Elymus caninus, Koeleria macrantha, Achnatherum occidentale, Carex praegracilis</i>, and <i>Muhlenbergia richardsonis</i>. Common forbs include <i>Symphyotrichum campestre var. bloomeri</i> and <i>Achillea millefolium</i>.
