Name: Abies lowiana - Chamaecyparis lawsoniana - Picea breweriana / Quercus vacciniifolia Forest Reference: NatureServe Biotics 2019 Description: This association occurs at moderate elevations of 1285-1420 m (4220-4650 feet) on northerly aspects in southwestern Oregon. The soil remains cold late into the growing season inhibiting water uptake. As the soil warms it also quickly dries and moisture becomes limiting. Moss covers more than 90% of the forest floor. Rocks on the ground surface are common, and the topsoil is coarse. This association is usually found on granodiorite substrates at the lower one-third of the slope, although it can occasionally be found on midslope benches. <i>Pseudotsuga menziesii</i> is seral on all sites and <i>Pinus lambertiana</i> and <i>Pinus monticola</i> occur in most stands. All of the tree species are well represented in the regeneration layer. <i>Quercus vacciniifolia</i> is the dominant shrub with an average cover of 40%. <i>Quercus sadleriana</i> shrubs are also common. <i>Mahonia nervosa</i> and <i>Arctostaphylos nevadensis</i> occur in all stands at low cover. The most common herbs are <i>Arnica cordifolia</i> and <i>Galium ambiguum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:28958-{9C5DC384-E9F6-4F5C-BB87-A769D003365F} Plot-observations of this Community Concept: 0
