Name: Pinus contorta var. contorta / Arctostaphylos columbiana Woodland Reference: Western Ecology Working Group of... Description: This woodland association occurs discontinuously along the Pacific coast between northern California and Tillamook Bay, Oregon. It occurs on all aspects on dry, partially stabilized sand dune ridges, slopes, and flats, between open sand and the edge of the forest. Habitat requirements appear to be minimal sand movement and well-drained sites. Burial by windblown sand occurs in some areas. These woodlands are dominated by Pinus contorta, with lesser amounts of Pseudotsuga menziesii, forming an open canopy with 20-55% cover. Pines in mature stands are between 80-130 years old. The shrub layer is dominated by Arctostaphylos columbiana and Vaccinium ovatum averaging 6 feet tall, with 45-95% cover. The ground layer is sparse, with small ericaceous plants such as Monotropa hypopithys, Hemitomes congestum, and Allotropa virgata (pinesap, Gnome-plant and candystick) occasionally found. The lichen flora on the shrub layer is diverse, with many cyanolichens, including several rare species. Droughty, nutrient-poor soils and slow growth make this a long-lived association. Small openings contain remnants of the earlier seral Pinus contorta / Arctostaphylos uva-ursi Forest (CEGL000134), with moss and reindeer lichens conspicuous.  Accession Code: VB.CC.22326.PINUSCONTORTAVA Plot-observations of this Community Concept: 0
