Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Giant Sequoia - Sugar Pine / Pacific Dogwood 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 in mid-slope positions on somewhat poorly drained clay loam and loam soils derived from granite. Elevations range from 1675-2290 m (5500-7500 feet), and aspects are variable. Litter/duff cover averages 85%. Sites are upland. The tree layer (over 50 m tall) averages 40% cover and is composed of Sequoiadendron giganteum and Pinus lambertiana. The tree layer between 10-50 m is composed of Abies lowiana, Pinus lambertiana, and Cornus nuttallii, averaging a total of 50% cover. Cornus nuttallii provides an average 25% cover in the shrub layer (1-5 m), while Corylus cornuta var. californica provides an average of 9% cover. The herb layer varies from 20-80% cover and averages 50%; Adenocaulon bicolor and Galium triflorum provide most of the cover in this layer. Other species in the herb layer include Asyneuma prenanthoides and Cornus nuttallii. Moss cover averages less than 5%.

Environmental Description: This association is found in mid-slope positions on somewhat poorly drained clay loam and loam soils derived from granite. Elevations range from 1675-2290 m (5500-7500 feet), and aspects are variable. Litter/duff cover averages 85%. Sites are upland.
Geographic Range: This forest occurs in limited stands (groves) along the western slope of California''s Sierra Nevada, scattered over a 420-km (260-mile) long strip which is less than 24 km (15 miles) wide, with most stands occurring in a 112-km (70-mile) long zone from Fresno to Tulare counties. The association is described from Yosemite NP, but is also tentatively described for Sequoia and Kings Canyon national parks.
