Common (Translated Scientific) Name: Sierra Lodgepole Pine / Ross'' Sedge 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. This association is found on lower to mid mountain slope positions from approximately 2500 to 3080 m (8200-10,100 feet) in elevation. Slopes are gentle to somewhat steep, with variable aspect. Soils are well-drained with textures ranging from loamy sand to gravels. They are derived primarily from granite, though sometimes metamorphic, bedrock. Litter/duff cover ranges from 35-45%, and large rock cover may be up to 20%. An herb layer ranging from <10 to 75% cover characterizes stands of this association. This layer is primarily Carex species; other species in the herb layer may include Phlox diffusa and Juncus parryi. There is no shrub layer. The tree layer is composed almost solely of Pinus contorta var. murrayana.

Geographic Range: While the alliance is widespread in the upper montane and subalpine zone of most major mountain ranges of the western U.S., this association has been described from Yosemite National Park. Information about its global characteristics is not available without additional inventory. It is suspected of occurring as far south as Sequoia and Kings Canyon national parks.
