Name: Cercocarpus ledifolius / Artemisia tridentata ssp. vaseyana Woodland Reference: Western Ecology Working Group of... Description: This association is documented in southeastern Oregon and southern Utah and possibly occurs in the Owyhee Uplands of Idaho, in scattered mountain ranges in the northern Great Basin region of Nevada and California, and the Colorado Plateau of western Colorado. Sites are well-drained loams or loamy sands over basalt, sandstone or rhyolite. Elevations range from 1600-1950 m (5250-6400 feet) in Oregon and around 2750 m (9025 feet) in Utah and Colorado. Aspects are variable, with slopes ranging from 0-60%. The vegetation is variable in its appearance. The canopy may be open to moderately closed, with a sparse to dense shrub understory. The canopy typically is dominated by <i>Cercocarpus ledifolius var. ledifolius</i>, which averages 50% cover but may have as much as 80% cover or as little as 20%. Common shrubs include <i>Artemisia tridentata ssp. vaseyana, Amelanchier alnifolia, Cercocarpus montanus, Paxistima myrsinites, Ericameria nauseosa (= Chrysothamnus nauseosus), Symphoricarpos oreophilus</i>, and <i>Chrysothamnus viscidiflorus</i>. <i>Elymus elymoides (= Sitanion hystrix)</i> and <i>Achnatherum lemmonii (= Stipa lemmonii)</i> are the most common grasses, but <i>Festuca idahoensis, Poa fendleriana, Pseudoroegneria spicata</i>, and <i>Poa secunda</i> may also be present. Stands may have emergent trees of <i>Pseudotsuga menziesii</i> that range in height from 15-20 m tall and provide less than 5% cover.  Accession Code: VB.CC.34156.CEGL001022 Plot-observations of this Community Concept: 0
