Name: Pseudotsuga menziesii - Pinus ponderosa - Calocedrus decurrens Forest Reference: NatureServe Biotics 2019 Description: This forest association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands are found at mesic sites at low to mid elevations (1400-1800 m [4600-5900 feet]) on concave and linear, north- and northwest-facing, moderately steep to steep (15-60%) slopes. Soils are typically medium to deep and well-developed with textures that are mostly loams but can be rocky. Parent material is usually granitic but is occasionally gabbro. Penetrability is easy to medium. Fire has been generally suppressed in these areas. Stands form a two-story structure with an intermittent tree layer dominated by <i>Pseudotsuga menziesii, Pinus ponderosa</i>, and <i>Calocedrus decurrens</i>. <i>Quercus kelloggii</i> and <i>Pinus lambertiana</i> are also usually present in the tree layer. <i>Abies lowiana</i> can be found contributing to minor cover at higher elevations. <i>Chamaebatia foliolosa</i> is often dominant in the shrub layer. <i>Toxicodendron diversilobum, Ceanothus integerrimus, Ceanothus</i> sp., <i>Cercocarpus montanus var. glaber</i>, and <i>Arctostaphylos patula</i> may be present in the shrub layer.  Accession Code: urn:lsid:vegbank.org:commConcept:36723-{59BA4451-5E6D-40EB-A0E0-6819902D1032} Plot-observations of this Community Concept: 0
