Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western Juniper / Oceanspray 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. This association is typically found between 2650 and 2800 m (8700-9200 feet) of elevation. Stands typically grow on southeast and southwest aspects with high solar radiation. Slopes are very steep, often more than 50%. Stands prefer middle and upper slope positions and have a high percentage of bare ground and surface rock, often more than 50%. Juniperus grandis is the dominant tree species. Pinus contorta and Pinus monticola are common associates. Holodiscus discolor is the diagnostic shrub species. Other shrubs that occur at lower frequency include Arctostaphylos nevadensis, Artemisia rothrockii, and Amelanchier utahensis.
