Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Mountain Hemlock - Sierra Lodgepole Pine / Purple Mountain-heath 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 high elevations (2620-3050 m [8600-10,000 feet]) on gentle to steep slopes (3-29°). Aspect ranges from south to northeast. Soils are generally, well-drained, poorly developed to moderately well-developed, with textures that range from rocky sand to rocky loam. Soil depths are moderately deep to deep. Parent material is granitic. Stands are characterized by Tsuga mertensiana and Pinus contorta, although Pinus contorta is less abundant. Occasionally, Pinus albicaulis and Pinus monticola may also be found contributing to minor cover in the tree layer. The understory is open and characterized by Phyllodoce breweri, which generally grows within the openings of the stand. Carex and Juncus are sometimes common in this association. Other species that may be found contributing to minor cover in the understory include Lupinus sp., Salix sp., Antennaria media, Pyrola minor, Mitella breweri, Calamagrostis stricta ssp. inexpansa, Ribes montigenum, Luzula parviflora, Solidago multiradiata, Senecio scorzonella, and Trisetum spicatum.
