Comm #12797	A.1321 » more details accession code: VB.CC.1094.A1321 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	Vegetation in this alliance occurs in subalpine meadows and the alpine tundra in the central and southern Rocky Mountains. The climate regime is continental, with long, cold winters and short summers with frequent afternoon thunderstorms. The majority of precipitation falls as snow in the winter and rain during late-summer thunderstorms. Stands are found above 2430 m in Idaho and 2980 m farther south in Utah on all aspects of gentle to moderate-gradient slopes. Stands are located on soils derived from sedimentary (sandstone) and igneous (basalt and granite) parent materials. ~Festuca brachyphylla$ is the dominant species in the herbaceous canopy. ~Trisetum spicatum$ is the most common associate. Other associated species include ~Artemisia scopulorum, Geum rossii, Lupinus lepidus, Lupinus sericeus, Polygonum bistortoides$, and ~Pseudocymopterus montanus$.

Comm #12799	A.2550 » more details accession code: VB.CC.1815.A2550 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	This is a poorly documented alliance known from the foothills and lower mountain slopes of the northern Rocky Mountains of east-central and southeastern Idaho and probably western Wyoming. This alliance is found at the upper elevation range of ~Artemisia tridentata ssp. vaseyana$, from 2590 to 3205 m (8500-10,500 feet) on deep to very deep, well-drained soils of mountain slopes and bottoms in zones of higher snow accumulation. Annual precipitation often exceeds 18 inches and occurs primarily as snow. The shrub layer ranges from 0.5-1.5 m tall, and shrub canopy cover is 10-60%, of which ~Artemisia tridentata ssp. spiciformis$ contributes at least 40% relative cover. Other shrubs that may be present include ~Artemisia tridentata ssp. vaseyana, Symphoricarpos oreophilus$, and ~Chrysothamnus viscidiflorus$. Perennial graminoid cover is typically less than 20%. Common species include ~Bromus carinatus$ and ~Carex geyeri$.
