Name: Krascheninnikovia lanata / Hesperostipa comata Dwarf-shrubland Reference: Western Ecology Working Group of... Description: This association is known from the Colorado Plateau in northwestern Colorado and eastern and southeastern Utah and the northwestern Great Plains in northeastern Montana. It has also been reported from Washington and may occur in Saskatchewan. In the Colorado Plateau stands occur on colluvial slopes at around 2000 m elevation and a canyon bottom at 1780 m elevation. Soils are moderately deep and sandy. In northeastern Montana, it is a minor type that occurs on the periphery of badlands and breaks usually on alluvial flats and gently sloping footslopes. Vegetation is characterized by an open to moderate (10-60% cover) dwarf-shrub layer dominated by <i>Krascheninnikovia lanata</i> with an open to moderate herbaceous layer dominated by <i>Hesperostipa comata</i>. On the Colorado Plateau, other shrubs occurring with minimal cover include <i>Artemisia tridentata ssp. wyomingensis, Chrysothamnus viscidiflorus</i>, and <i>Gutierrezia sarothrae</i>. The herbaceous layer is dominated by <i>Hesperostipa comata</i>; other grasses, such as <i>Bromus tectorum, Poa secunda, Poa fendleriana</i>, and <i>Achnatherum hymenoides</i>, may occur with few forbs. In the northwestern Great Plains, constant associates are <i>Artemisia frigida, Bouteloua gracilis</i>, and <i>Carex filifolia</i> with <i>Atriplex nuttallii, Artemisia tridentata, Gutierrezia sarothrae, Koeleria macrantha</i>, and <i>Poa secunda</i>. Forbs such as <i>Phlox hoodii, </i><i>Plantago patagonica</i>, and <i>Sphaeralcea coccinea</i> are inconspicuous and contribute little cover. Introduced species <i>Bromus japonicus, Bromus tectorum</i>, and <i>Melilotus officinalis</i> are often present but not abundant.  Accession Code: VB.CC.33504.CEGL001327 Plot-observations of this Community Concept: 0
