CEGL002813 Artemisia tridentata ssp. wyomingensis / Leymus salinus Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Wyoming Big Sagebrush / Saline Wildrye Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association has been described from Dinosaur National Monument in northwestern Colorado and Bryce National Park in southern Utah, but may be expected on marine shale substrates in southern Wyoming and northeastern Utah as well. The association occupies badland hills of Mancos and Tropic shales from 1700 to 2132 m (5600-8600 feet) in elevation. The barren, rocky substrate has clayey to sandy loam well-drained soils. The vegetation is dominated by Artemisia tridentata ssp. wyomingensis with 10-30% cover. Artemisia frigida, Atriplex confertifolia, Chrysothamnus viscidiflorus, and Gutierrezia sarothrae are often present with sparse cover. Leymus salinus dominates the herbaceous understory with 1 to 12% cover and is typically associated with Achnatherum hymenoides. Forb species typically include Erysimum asperum, Phlox hoodii, and Stenotus acaulis.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The floristics are similar to the Artemisia tridentata ssp. wyomingensis - Atriplex confertifolia / Elymus salina Association described by (Baker 1982b), but it is not codominated by both shrub species.

Environmental Description: The shrubland occurs on very steep (60-75%), south-facing mountain and canyon slopes and gentle valley bottoms, from 1700 to 2620 m (5600-8600 feet) elevation. Coarse loamy sand soils on these dry, exposed sites are dominated by boulders, rock or bare ground, derived from gneiss and other metamorphic rock or sedimentary materials. The association occupies badland hills of Mancos and Tropic shales. The barren, rocky substrate has clayey to sandy loam well-drained soils.
Geographic Range: This shrubland is known from exposures of Mancos shale adjacent to the east end of Dinosaur National Monument in northwestern Colorado, and on Tropic shale in western Bryce Canyon National Park, and may be expected on marine shale substrates in southern Wyoming and northeastern Utah as well.
