Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Jeffrey Pine / Curl-leaf Mountain-mahogany Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland 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. Elevations range from 2285 to 2650 m (7500-8700 feet), and aspects are variable. This association is found in low to high slope positions. Soils are moderately well- to well-drained loamy sands and sandy loams derived primarily from granite. Sites are upland. Pinus jeffreyi is the sole mature tree in sampled stands. Trees range from 10-50 m in height. Abies lowiana and Pinus albicaulis saplings occur infrequently in the shrub layer. Shrubs include Cercocarpus ledifolius and Artemisia tridentata. The herbaceous layer varies from 5-50% cover. Elymus elymoides is the only frequent species in the herb layer. Other herb species include Leptosiphon pachyphyllus, Poa secunda, and Wyethia mollis.
