Name: Artemisia cana ssp. cana / Pascopyrum smithii Shrub Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This association has been described from the Great Plains of central and eastern Montana, far western North Dakota, northwestern South Dakota, and northeastern Wyoming. It occupies terraces and floodplains along streams, where alluvium contains more soil water than is available in the uplands. Artemisia cana ssp. cana dominates the shrub layer, which may also include small amounts of Symphoricarpos occidentalis, Sarcobatus vermiculatus, or Chrysothamnus sp. The undergrowth typically is dense and composed mainly of graminoids, with forbs contributing little cover. Pascopyrum smithii often dominates, and in many stands several other species may codominate, especially Nassella viridula, Poa pratensis, and Bromus japonicus (or another exotic, annual brome grass). Exotic grasses (Poa pratensis, Bromus japonicus) dominate the undergrowth in many stands. Bouteloua gracilis and Carex filifolia, both more typically upland species, may contribute substantial cover. Common forbs are Taraxacum spp. (exotic), Achillea millefolium, Artemisia ludoviciana, and Vicia americana.  Accession Code: VB.CC.20584.ARTEMISIACANASS Plot-observations of this Community Concept: 0
