Name: Pinus contorta var. murrayana Subalpine Forest & Woodland Alliance
Reference: NatureServe Biotics 2019
Description: This alliance consists of forests and woodlands dominated by <i>Pinus contorta var. murrayana</i> with shrub, grass or barren understories. Understories are open, with scattered shrubs and herbaceous species, which do provide a continuous fuel bed for fire. Trees can be old and can attain diameters of 1.2 m (4 feet). Associated plant species include <i>Arctostaphylos nevadensis, Artemisia tridentata, Ceanothus cordulatus, Cercocarpus ledifolius</i> (although not that common, just occasional in drier sites), <i>Chrysolepis sempervirens, Phyllodoce breweri</i>, and <i>Ribes montigenum</i>. Common graminoids include <i>Carex exserta, Carex filifolia, Carex rossii</i>, and <i>Poa wheeleri</i>. This alliance is widespread in glacial basins at upper montane to subalpine elevations of the central and northern Sierra Nevada and Transverse and Peninsular ranges where cold-dry conditions exist (1800-2450 m [6000-8000 feet] in the north and 2450-3600 m [8000-11,800 feet] in the south). It also occurs on extensive broad ridges and pumice plateaus of the southern Cascades in Oregon (the broad ridges that form the Cascade Crest in southern Oregon tend to be dominated by extensive stands of lodgepole pine). Soils are often shallow and coarse-textured.
