Name: Abies magnifica - Pinus monticola - Pinus contorta var. murrayana Forest Reference: NatureServe Biotics 2019 Description: These forests are found in the upper-elevation eastside and westside of the central and southern Sierra Nevada, California, typically above 2590 m in elevation. This is the highest elevation association of the mixed <i>Abies magnifica</i> and <i>Pinus monticola</i> associations. Aspects are varied, but are predominantly northeast and northwest. Sites are mostly on ridges and upper and middle slope positions. Soils are predominantly derived from granite, and may form on bedrock or alluvium or glacial till. They are typically shallow sands or sandy loams, and well-drained or excessively drained. There is much exposed gravel at the surface. Stands are moderately dense forests with sparse understories. Total vegetation cover is generally lower than other forests in the <i>Abies magnifica</i> alliance. Overstory composition is characterized by a mix of <i>Pinus monticola, Pinus contorta var. murrayana</i>, and <i>Abies magnifica</i>. Tree cover averages about 63% (range 37-91%). Shrub cover is virtually nonexistent, averaging 1% (no characteristic species), although conifer regeneration is moderate to high. The herb layer averages about 12% cover and includes <i>Arabis platysperma, Carex rossii, Pedicularis semibarbata</i>, and <i>Achnatherum occidentale</i> as the principal species.  Accession Code: urn:lsid:vegbank.org:commConcept:36664-{2004A1ED-9466-4BAE-82CC-513E13D52FA6} Plot-observations of this Community Concept: 0
