CEGL008667 Pinus contorta var. murrayana / Carex exserta Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sierra Lodgepole Pine / Shorthair 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%. Stands are characterized by an herb layer of primarily Carex exserta. What negligible shrub layer exists consists primarily of young Pinus contorta var. murrayana. The tree layer is composed solely of Pinus contorta var. murrayana, ranging up to 20 m in height. Other herb species that may be present include Achnatherum and Elymus elymoides.

Floristics: Stands are characterized by an herb layer of primarily Carex exserta (= Carex filifolia var. erostrata). What negligible shrub layer exists consists primarily of young Pinus contorta var. murrayana. The tree layer is composed solely of Pinus contorta var. murrayana, ranging up to 20 m in height. Other herb species that may be present include Achnatherum and Elymus elymoides.

Environmental Description: 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%.
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 likely that this association occurs as far south as at least Sequoia and Kings Canyon national parks.
