CEGL008614 Abies magnifica - Pinus monticola / Chrysolepis sempervirens Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: California Red Fir - Western White Pine / Bush Chinquapin Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This forest/woodland association is located at higher elevations primarily in the southern and eastern portions of the upper montane in the central and southern Sierra Nevada, California. Yosemite National Park may be near the northern limit of its range. This association typically occurs above 2440 m (8000 feet) with many stands occurring over 2593 m ( 8500 feet) in elevation. Aspects are predominantly northeast and northwest, and the majority of stands are located on upper and middle slopes that are somewhat steep or steeper. Soils are generally derived from granite but may be volcanic or metamorphic in origin and may have evolved in place or formed from alluvium. Soils are typically excessively drained sand or sandy loam that are shallower than most forested sites in the upper montane of the Sierra Nevada. Stands are open with a prominent shrub understory. Overstory composition is characterized by Pinus monticola mixed with Abies magnifica. In some stands, Pinus monticola may reach 50% cover, but in most cases Abies magnifica is the dominant species. Chrysolepis sempervirens is the dominant shrub species. In some cases Arctostaphylos patula is present in substantial amounts, and stands take on the appearance of a mixed shrub plant community. These two shrubs indicate the dry conditions of these stands. The sparse herb layer is composed of widely scattered Arabis platysperma, Penstemon caesius, Pyrola picta, and Erysimum capitatum var. perenne.

Floristics: Stands are open woodlands with a prominent shrub understory. Overstory composition is characterized by Pinus monticola mixed with Abies magnifica, for a tree cover averaging 51%. In some stands, Pinus monticola may reach 50% cover, but in most cases Abies magnifica is the dominant species. Shrub cover averages 29%, with Chrysolepis sempervirens as the dominant species. In some cases Arctostaphylos patula is present in substantial amounts, and stands take on the appearance of a mixed shrub plant community. These two shrubs indicate the dry conditions of these stands. The herb layer averages less than 10% cover and is composed of widely scattered Arabis platysperma, Penstemon caesius, Pyrola picta, and Erysimum capitatum var. perenne (= Erysimum perenne).
