Name: Eriogonum pyrolifolium Herbaceous Alliance Reference: Western Ecology Working Group of... 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.  Accession Code: VB.CC.20533.ERIOGONUMPYROLI Plot-observations of this Community Concept: 0
