Name: Pinus jeffreyi - Abies magnifica Woodland Reference: Western Ecology Working Group of... Description: This association occurs on the eastern slopes of the upper montane of the Sierra Nevada, California. It is found at the highest elevations of all the Pinus jeffreyi-dominated communities, ranging from 7300-9100 feet, but typically above 8500 feet. Aspects are generally southeastern through southwestern on slopes that are commonly somewhat steep to steep. Soils are derived from granitic bedrock or pumice cinders. Soils are characteristically deep and are gravelly sands. Soils are typically excessively drained, and are warm, given the dominant aspects. Stands in this association are somewhat open forests with sparse understories composed of scattered shrub and herb patches. The overstory is distinguished by the presence of Pinus jeffreyi, which averages 26%. Abies magnifica is generally present as well, but sometimes occurs in the middle and lower layers of the tree canopy. Pinus contorta var. murrayana is an infrequent component of the composition. Shrub cover is very low on most sites; however, in the southern portion of the range stands can be dominated by Chrysolepis sempervirens. In the north, Artemisia tridentata, Purshia tridentata, and Chrysothamnus viscidiflorus are present in a few cases. Arabis platysperma, Eriogonum nudum, and Achnatherum occidentale are the most frequent species in the herb layer, which averages between 20 and 25% cover.  Accession Code: VB.CC.21836.PINUSJEFFREYIAB Plot-observations of this Community Concept: 0
