Name: Artemisia cana ssp. bolanderi / Muhlenbergia richardsonis Shrub Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This association occurs on playa bottoms and on moist sites in valley bottoms in the northern Great Basin of southeastern Oregon, northwestern California, extreme southwestern Idaho and northeastern Nevada. It ranges between thick shrublands to open grasslands with scattered shrubs. It has only been described from arid, closed basins, although generally in areas with sufficient freshwater input to allow <i>Artemisia cana</i> to grow. All stands are in vernally wet areas, with the characteristics of intermountain vernal pools. <i>Artemisia cana ssp. bolanderi</i> dominates the shrub layer of all sites, generally as the only shrub present. <i>Artemisia tridentata</i> or less frequently <i>Sarcobatus vermiculatus</i> are occasionally found in stands, generally occurring at the margins of the communities. <i>Artemisia cana ssp. bolanderi</i> cover ranges from 5-60%, so that this type can be found as grasslands with shrubs, steppe and most commonly as shrublands. The perennial grass <i>Muhlenbergia richardsonis</i> comprises most of the understory. Occasionally, <i>Puccinellia</i> spp., <i>Elymus</i> spp., <i>Poa secunda, Juncus nevadensis, Juncus effusus</i>, or <i>Eleocharis</i> spp. are present. Often, <i>Muhlenbergia richardsonis</i> forms a solid, short mat across the stands, although in dry years or drier locations, alkaline playa (bare ground) makes up to 40% of the cover.  Accession Code: VB.CC.34014.CEGL001743 Plot-observations of this Community Concept: 0
