Name: A.1644
Reference: EcoArt 2002
Description: This alliance occurs in subalpine and alpine habitats of the high mountains of the Pacific Northwest. The climate is cold and snowy with severe winds, snow abrasion, and a short growing season. Elevations where the alliance is found range from 1700-2400 m in the Cascades. Stands of this alliance typically occur on exposed, well-drained substrates. There are often late-lying snowpacks but some late-summer drought is possible. In the northern Cascades, the communities have been described as snowbed types. Vegetation in this alliance forms sparse, distinctive communities with ~Eriogonum pyrolifolium$ usually dominant, but often low in cover. ~Luzula piperi$ is the most common associate, but ~Carex pyrenaica, Erigeron aureus, Poa secunda (= Poa sandbergii), Sibbaldia procumbens$, and ~Antennaria alpina$ occur in stands in the North Cascades.
