Name: Eriogonum spp. - Luzula spp. Alpine Snowbed Alliance Reference: NatureServe Biotics 2019 Description: The vegetation is characterized by low-growing (3-8 cm), mat-forming perennial forbs and graminoids, which can be sparse, with less than 25% total cover. <i>Eriogonum pyrolifolium, Saxifraga tolmiei</i>, and <i>Luzula piperi</i> can be dominant to codominant. Other commonly associated herbaceous species include <i>Carex nigricans, Carex pyrenaica, Carex spectabilis, Juncus drummondii, Luetkea pectinata, Lupinus arcticus ssp. subalpinus, Lupinus latifolius</i>, or <i>Oreostemma alpigenum var. alpigenum</i>. Bryophytes such as <i>Polytrichum sexangulare</i> and <i>Marsupella brevissima</i> may also be present. This alliance is found in the subalpine and alpine of the Cascade Range of Washington and British Columbia. It appears to be restricted to the western side of the North Cascades where a maritime climate predominates. Stands occur between 1750 and 2100 m elevation on gentle to moderately steep north- or south-facing slopes. It is a snowbed habitat where snow remains on the ground until late July or early August, occurring above treeline on north-facing, gentle to moderate slopes with very late snowmelt and well-drained soils. It can also occur in subalpine parklands, where it tends to occur on north-facing slopes. Soils can be unstable, poorly to moderately well-drained, and somewhat acidic with a pH between 4.7 and 5.9.  Accession Code: urn:lsid:vegbank.org:commConcept:38623-{63BC63EA-21B8-436D-8EC4-A8086720616F} Plot-observations of this Community Concept: 0
