Common (Translated Scientific) Name: Mountain Hemlock - Sierra Lodgepole Pine - Western White Pine Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This forest association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands are found at mid to high elevations (2470-2925 m [8100-9600 feet]) on flat to steep slopes (0-32°). These slopes are on all aspects; however, they are predominantly found on north-, northwest- and east-facing slopes. Soils are poorly developed to moderately well-developed with textures ranging from rocky gravel to gravelly loam. These soils are well-drained and depth ranges from shallow to deep. Parent material is granitic. Stands are characterized by Tsuga mertensiana, Pinus contorta, and Pinus monticola; however, Tsuga mertensiana is most abundant. Abies magnifica is occasionally present in the overstory. The understory herb and shrub layers are open and include Juncus sp., Lupinus sp., Ribes montigenum, Arctostaphylos nevadensis, Carex sp., Salix sp., and a variety of other species contributing to minor cover.
