Name: A.1653
Reference: EcoArt 2002
Description: This alliance is found in the subalpine and alpine of the North Cascade Range of Washington and British Columbia. Stands occur between 1750 and 2100 m elevation on gentle to moderately steep south-facing slopes. This vegetation appears to be restricted to the western side of the North Cascades where a maritime climate predominates. ~Saxifraga tolmiei$ communities are associated with a snowbed habitat where snow remains on the ground until late July or early August. Soils are unstable, poorly to moderately well-drained, and somewhat acidic with a pH between 4.7 and 5.9. Stands are dominated by ~Saxifraga tolmiei$, a low-growing (3-8 cm), mat-forming perennial forb. The graminoid ~Luzula piperi$ is a constant associate. Less common graminoid species include ~Carex pyrenaica$ and ~Juncus drummondii$. The bryophytes ~Polytrichum sexangulare$ and ~Marsupella brevissima$ are usually present.
