Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Littleleaf Pussytoes - Alpine Sagebrush Alpine Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This alpine vegetation type apparently has been described only from three stands at about 3265 m (10,700 feet) elevation on Carter Mountain along the eastern edge of the Absaroka Mountains in northwestern Wyoming. Stands of this association occur on the lower portions of relatively steep, leeward slopes where snow accumulation is thought to be moderate. The vegetation consists of a single strata of scattered forbs, graminoids, and cushion plants up to 20 cm tall, with Antennaria microphylla and Artemisia scopulorum contributing 25% of the standing crop of herbage. Other forbs contributing substantial standing crop are Achillea millefolium, Oxytropis parryi, Cerastium arvense, and Lomatium cous. Graminoids contribute about 24% of the standing crop, and the most abundant taxa are Poa spp., Koeleria macrantha, Festuca rubra, and Carex elynoides.
