Name: A.1305
Reference: EcoArt 2002
Description: Vegetation included in this alliance occurs in the alpine fellfields in the Washington Cascades. Elevations range from 2290-2370 m. Stands are on rocky, exposed, often unstable slopes and lateral moraines. Sites are relatively dry because high winds allow little snow accumulation. Soils are shallow, poorly developed and lithic, derived from quartz diorite. The growing season is relatively short because the soil dries out late in the growing season. This vegetation has a sparse, low-growing herbaceous layer usually less than 20 cm tall that is codominated by ~Carex proposita$ and ~Lupinus lepidus$. Other associated species include ~Chamerion latifolium (= Epilobium latifolium), Antennaria alpina, Juncus parryi$, and ~Phacelia sericea$. Adjacent vegetation includes alpine turf communities in more mesic sites.
