Name: Artemisia tridentata ssp. tridentata / Hesperostipa comata Shrubland
Reference: Western Ecology Working Group of...
Description: This shrubland association occurs in small to large patches on point bars, stream terraces, valley floors and alluvial fans in the interior western U.S. and possibly British Columbia, Canada. Slopes are generally gentle but can range up to 20% in steeper tributary drainages. Elevations range from 1220 to 2000 m at any aspect. Soils are sandy loams or loamy sands derived from alluvium. Although associated with drainages and floodplains, this community occurs in sites that rarely flood. Total vegetation cover tends to be somewhat sparse, as many examples have had their herbaceous cover reduced by grazing; undisturbed examples have total vegetation cover up to 90%. The dominant shrub is <i>Artemisia tridentata ssp. tridentata</i>. Others occurring as scattered individuals include <i>Ericameria nauseosa, Chrysothamnus viscidiflorus, Ephedra viridis, Krascheninnikovia lanata, Opuntia polyacantha</i>, and <i>Atriplex canescens</i>. The understory is dominated or codominated by the native bunchgrass <i>Hesperostipa comata</i>. Common herbaceous associates include <i>Achnatherum hymenoides, Bouteloua gracilis, Poa secunda, Sporobolus cryptandrus</i>, and <i>Sphaeralcea coccinea</i>. Moss and cryptogamic crusts may have significant cover in sites that have not experienced recent grazing.
