CEGL008680 Abies lowiana - Pinus lambertiana / Maianthemum racemosum - Prosartes hookeri Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sierra White Fir - Sugar Pine / Feathery False Lily-of-the-Valley - Drops-of-Gold Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This evergreen forest association has been described from the northern Sierra Nevada and southern Cascade Ranges in California. In the northern Sierra Nevada, elevations average 1525 m (5000 feet), and aspects are northeast, east, and northwest. Slopes range from gentle to steep. The association occurs in upper and midslope positions, and soils are gravelly sandy loams, sandy loams and loams, and are often derived from volcanic substrates. Mature forests have a moderately dense to dense conifer overstory often codominated by variable mixtures of Abies lowiana, Calocedrus decurrens, Pinus lambertiana, and Pinus ponderosa. The understory is sparse, with Maianthemum racemosum and Prosartes hookeri being most prevalent. Chimaphila menziesii is also a constant species.

Floristics: Mature forests have a moderately dense to dense conifer overstory often codominated by variable mixtures of Abies lowiana (= Abies concolor var. lowiana), Calocedrus decurrens, Pinus lambertiana, and Pinus ponderosa. Abies lowiana averages 51% cover; the other conifers average 11-36% cover. The understory is sparse, with Maianthemum racemosum (= Smilacina racemosa) and Prosartes hookeri (= Disporum hookeri) being most prevalent. Chimaphila menziesii is also a constant species.
