CEGL001534 Artemisia tridentata ssp. wyomingensis / Mixed Grasses Shrub Grassland
Type Concept Sentence: This association is currently only described from Bighorn Canyon National Recreation Area, Wyoming. Additional global information will be added as it becomes available. Slopes where it is found are low (0-7%) and aspects are various. Soils are well-drained and dry, with a texture ranging from sandy loam, silt loam, sandy clay, and silt. Small rocks (1-35% cover), litter (3-40%), and bare ground (10-74%) are the biggest components of the unvegetated layer. Artemisia tridentata ssp. wyomingensis is the most common and abundant dwarf-shrub found at these sites, though Gutierrezia sarothrae and Artemisia frigida may also be commonly encountered. The shrub stratum typically has cover ranging from 10-75%. Herbaceous species are more diverse than the shrub species, and Pseudoroegneria spicata, Bouteloua gracilis, Hesperostipa comata, and Carex filifolia are common.
