Type Concept: This description is based on occurrences at Craters of the Moon National Monument and Preserve in Idaho. Additional global information will be added as it becomes available. A combination of Artemisia tridentata ssp. vaseyana and Purshia tridentata dominate the canopy of this shrubland association. Other shrubs, such as Ericameria nauseosa and Eriogonum microthecum may also occur regularly. Shrub cover can range from 25 to 75%, and cover of the shrub stratum is greater than that of the herbaceous stratum. Pseudoroegneria spicata is typically the most abundant grass in the relatively sparse herbaceous understory. Other perennial grasses, such as Poa secunda, Elymus lanceolatus, Hesperostipa comata, and Bromus tectorum (exotic) are often present as well. Forbs occur at very low cover values and often include Eriogonum heracleoides, Crepis acuminata, Phacelia hastata, and Penstemon deustus. Soils that support this plant association can range from xeric sites with shallow soils to sites where soils are deep and well-developed. Soil texture ranges from silt loams to sandy loams.
