Common (Translated Scientific) Name: Beach Pine - Douglas-fir / California Wax-myrtle - California Huckleberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This mid- to late-seral forest association is found on sand dunes along the Pacific Coast between northern California and Tillamook Bay, Oregon, where it occurs on warm, dry ridges and slopes, primarily with south- to west-facing aspects. The poorly developed humus layer is rarely more than 2.5 cm (1 inch) thick on slopes, but where organic material accumulates at the toe of slopes the layer may be up to 23 cm (9 inches) deep. Stands are dominated by Pinus contorta and Pseudotsuga menziesii, with low incidence of Picea sitchensis and Tsuga heterophylla. Pseudotsuga menziesii becomes increasingly scarce on dunes farther north, where it is replaced by Picea sitchensis. Arbutus menziesii is often present on ridges and toeslopes. Total canopy cover ranges from 40-85%. Live basal area is one of the lowest of the native forest stands occurring on coastal sand dunes. Conifer reproduction is sparse or nonexistent. Stands are typically littered with fallen trees, mostly Pinus contorta. The shrub layer, dominated by the ubiquitous Vaccinium ovatum and Gaultheria shallon, ranges from 5-95%, with an average height of 2.4 m (8 feet). The lowest shrub cover appears to be on dry, warm exposures, where bracken fern may be conspicuous. The ground layer is otherwise sparse to nonexistent. Charcoal is present in some stands.
