Name: Abies lowiana - Calocedrus decurrens - Pinus lambertiana / Adenocaulon bicolor Forest Reference: NatureServe Biotics 2019 Description: This association has been described from the northern Sierra Nevada and southern Cascade Range in California. This association occurs on cool, moist, gently sloping sites with well-developed soils at elevations averaging 1435 m (4700 feet). Sites are north-, northeast- and northwest-facing lower slopes, benches, or swales, and are often associated with headwater areas or seasonal streams. Substrates are variable. This is a late-successional forest characterized by a dense, several-layered conifer overstory and an herb layer dominated by <i>Adenocaulon bicolor</i>. <i>Abies lowiana, Calocedrus decurrens</i>, and frequently <i>Pseudotsuga menziesii</i> codominate all layers of the diverse overstory. <i>Pinus lambertiana</i> is consistently a minor associate. <i>Pinus ponderosa</i> sometimes occurs in low amounts. Regeneration is dominated by <i>Abies lowiana</i> and <i>Calocedrus decurrens</i>, but <i>Pseudotsuga menziesii</i> and <i>Pinus lambertiana</i> are frequent in low amounts. The shrub layer is variable, with no shrubs or variable amounts of <i>Symphoricarpos mollis</i>. <i>Adenocaulon bicolor</i> dominates the usually well-developed herb layer, indicating moist soils. Other herbs include <i>Maianthemum racemosum, Osmorhiza berteroi, Galium triflorum</i>, and <i>Prosartes hookeri</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:36717-{E2FE28FD-6534-4007-877D-C980FB06B320} Plot-observations of this Community Concept: 0
