Reference: EcoArt 2002
Description: This subalpine and alpine sod grassland of California and Oregon occurs on dry meadows, flats, and slopes from 1300-3800 m elevation. Optimal habitats have subsurface moisture. The precipitation regime where this alliance occurs is strongly seasonal, with most precipitation falling in the winter months. Most precipitation in the upper elevational range falls as snow. Summers are very dry. This alliance forms large stands, which often intergrade with other meadow, forest, and woodland alliances. ~Calamagrostis breweri$ as an important or dominant grass in the herbaceous layer, with ~Ptilagrostis kingii$ as an important canopy species.
