Reference:
NatureServe Biotics 2019
Description:
This mesic shrubland and steppe alliance is distributed from the Columbia Basin east to the northern Rocky Mountains and is characterized by an open to moderately dense shrub layer dominated or codominated by <i>Artemisia tripartita</i> with10-25% cover and with herbaceous species having equal or greater coverage than shrubs. Common shrub associates include <i>Artemisia frigida, Artemisia tridentata ssp. tridentata, Artemisia tridentata ssp. vaseyana, Chrysothamnus viscidiflorus, Krascheninnikovia lanata, Purshia tridentata</i>, or <i>Tetradymia canescens</i>. The herbaceous stratum is typically dominated by graminoids and of moderate to moderately high cover (20-70%). <i>Pseudoroegneria spicata</i> and <i>Festuca idahoensis</i> are the most common associates. Other locally abundant graminoid species include <i>Bouteloua curtipendula, Bouteloua gracilis, Carex filifolia, Festuca campestris, Hesperostipa comata</i>, and <i>Koeleria macrantha</i>. Forbs form a minor and highly variable portion of this vegetation. Recurrent species include <i>Achillea millefolium, Balsamorhiza sagittata, Camelina microcarpa, Erigeron</i> spp., <i>Opuntia</i> spp., <i>Phlox</i> spp., and <i>Sphaeralcea coccinea</i>. Climate ranges from semi-arid in intermountain basins to subhumid in higher elevations of the Rocky Mountains. Stands occur on flat to steeply sloping upland sites. Soil texture is loam, sandy loam, or clay loam, but is highly variable.
