CEGL008678 Abies lowiana - Calocedrus decurrens - Pinus lambertiana / Adenocaulon bicolor Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sierra White Fir - Incense-cedar - Sugar Pine / American Trailplant Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: 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 Adenocaulon bicolor. Abies lowiana, Calocedrus decurrens, and frequently Pseudotsuga menziesii codominate all layers of the diverse overstory. Pinus lambertiana is consistently a minor associate. Pinus ponderosa sometimes occurs in low amounts. Regeneration is dominated by Abies lowiana and Calocedrus decurrens, but Pseudotsuga menziesii and Pinus lambertiana are frequent in low amounts. The shrub layer is variable, with no shrubs or variable amounts of Symphoricarpos mollis. Adenocaulon bicolor dominates the usually well-developed herb layer, indicating moist soils. Other herbs include Maianthemum racemosum, Osmorhiza berteroi, Galium triflorum, and Prosartes hookeri.

Floristics: This is a late-successional forest characterized by a dense, several-layered conifer overstory and an herb layer dominated by Adenocaulon bicolor. Abies lowiana (= Abies concolor var. lowiana), Calocedrus decurrens, and frequently Pseudotsuga menziesii codominate all layers of the diverse overstory. Pinus lambertiana is consistently a minor associate. Pinus ponderosa sometimes occurs in low amounts. Regeneration is dominated by Abies lowiana and Calocedrus decurrens, but Pseudotsuga menziesii and Pinus lambertiana are frequent in low amounts. The shrub layer is variable, with no shrubs or variable amounts of Symphoricarpos mollis. Adenocaulon bicolor dominates the usually well-developed herb layer, indicating moist soils. Other herbs include Maianthemum racemosum (= Smilacina racemosa), Osmorhiza berteroi (= Osmorhiza chilensis), Galium triflorum, and Prosartes hookeri (= Disporum hookeri).
