Description: Stands of this widespread montane to subalpine shrubland alliance of California occur on ridges and slopes with thin soils. Soils are skeletal and may be rocky, loamy, or sandy. Stands are found between 700 and 2800 m elevation. The widespread range of this alliance includes a large variety of habitats, and yearly precipitation and temperature ranges are quite large. The northern portion of the range can receive 200 cm of rain per year, while southern stands may receive only 40 cm per year. Lower elevation, southern stands may never see freezing temperatures, while northern, high-elevation stands may only have a five-month growing season. Unlike most chaparral types, this alliance forms self-perpetuating stands. This montane and alpine shrubland forms an intermittent canopy. ~Holodiscus discolor$ is the sole, dominant or important species in the canopy. Other shrubs may include ~Prunus emarginata, Chrysolepis sempervirens (= Castanopsis sempervirens), Symphoricarpos mollis, Garrya fremontii, Arctostaphylos patula, Quercus vacciniifolia, Quercus sadleriana, Eriogonum nudum, Ericameria nauseosa (= Chrysothamnus nauseosus), Amelanchier alnifolia, Mimulus suksdorfii, Ceanothus velutinus, Keckiella corymbosa$, and ~Achnatherum occidentale (= Stipa occidentalis)$. Emergent conifers may be present.
