Description:
This is a broadly defined, semi-arid upland shrubland currently described from western Colorado, Nevada, and Utah and is likely more widespread. Elevations range from 1169 to 2420 m (3834-8000 feet). Stands occur on flat to gently sloping (<8%), dry alluvial terraces above ephemeral washes or perennial stream and river channels or may form a band in the alluvial flats above playas. Substrates are deep, moderately well- to well-drained silty clay loam to sandy loam soils derived from stratified alluvium. The ground surface has moderate to high cover of bare soil. The vegetation is characterized by a moderately dense to dense (40-70% cover) shrub canopy dominated by <i>Ericameria nauseosa</i> shrubs 0.5-3 m tall, with a relatively sparse herbaceous layer. Some stands have low diversity, others have additional associated short and dwarf-shrubs such as <i>Artemisia frigida, Artemisia tridentata ssp. wyomingensis, Atriplex canescens, Chrysothamnus viscidiflorus, Gutierrezia sarothrae, Psorothamnus polydenius, Rosa woodsii, Sarcobatus vermiculatus</i>, and <i>Tetradymia tetrameres</i>. The sparse herbaceous layer is a mixture of grasses and forbs. Grass cover is generally low and may include native species such as <i>Achnatherum lettermanii, Achnatherum hymenoides, Distichlis spicata, Pseudoroegneria spicata, Sporobolus airoides</i>, and <i>Elymus elymoides</i>. Non-native grasses include <i>Bromus tectorum</i> and <i>Poa pratensis</i>. Common forbs may include the native species <i>Erigeron flagellaris, Tragopogon dubius, Achillea millefolium, Agoseris glauca, Potentilla crinita, Artemisia ludoviciana, Eriogonum hookeri, Rumex salicifolius</i>, and <i>Verbesina encelioides</i>.
