CEGL002993 Artemisia tridentata ssp. spiciformis Shrub Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Spiked Big Sagebrush Shrub Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland concept is based on stands entirely from Wyoming and contains stands dominated by Artemisia tridentata ssp. spiciformis with Festuca idahoensis and other grasses dominant in the undergrowth (30 plots), and stands dominated by Balsamorhiza sagittata and other forbs, with very little cover by graminoids in the undergrowth (6 plots). Further inventory and data collection may warrant creation of two separate associations.

Classification Comments: There may be two types here: Artemisia tridentata ssp. spiciformis / Festuca idahoensis (Bramble-Brodahl 1978, n=4; Tart 1996, n=26) and Artemisia tridentata ssp. spiciformis / Balsamorhiza sagittata (Teton NP, n=6 ). Possibly change ~Artemisia tridentata ssp. spiciformis Shrub Grassland (CEGL002993)$$ to Artemisia tridentata ssp. spiciformis / Festuca idahoensis Shrub Herbaceous Vegetation or create a new type. Bramble-Brodahl (1978) describes an Artemisia tridentata ssp. spiciformis / Mountain Forb Habitat Type that is dominated by Festuca idahoensis and has Geum triflorum and Lupinus argenteus. Tart (1996) describes two Artemisia tridentata ssp. spiciformis plant associations, both dominated by Festuca idahoensis with Elymus trachycaulus as most abundant and with the highest cover. The 6 plots from Teton National Park fit neither of these descriptions and are dominated by forbs such as Balsamorhiza sagittata, Eriogonum umbellatum, and Lupinus argenteus. Elymus trachycaulus is present in 4 of 6 plots.
