Name: Abies concolor - Calocedrus decurrens - Pinus lambertiana / Adenocaulon bicolor Forest
Reference: Western Ecology Working Group of...
Description: This association has been described from the northern Sierra Nevada and southern Cascade Ranges 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 concolor, 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 concolor</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 (= Smilacina racemosa), Osmorhiza berteroi (= Osmorhiza chilensis), Galium triflorum</i>, and <i>Prosartes hookeri (= Disporum hookeri)</i>.
