Name: Pinus monticola - Pseudotsuga menziesii / Quercus vacciniifolia - Lithocarpus densiflorus Woodland Reference: Western Ecology Working Group of... Description: These woodlands are restricted to a very narrow area of serpentine habitat in southwestern Oregon and northwestern California. They occur at low to mid elevations, ranging from 610 to 1220 m (2000-4000 feet), generally on rocky, serpentine or rarely hornblende or basalt slopes. Aspects are mostly southeast, but range to south and west. Slope position range from ridgetops to the upper 1/3 slope. This is a woodland dominated by <i>Pinus monticola</i> (17-20% cover), <i>Pseudotsuga menziesii</i> (5-8%), and occasionally <i>Pinus attenuata</i> (6%) or <i>Pinus contorta</i> (30%). The shrub cover is fairly high and quite diverse, although <i>Lithocarpus densiflorus</i> (<i>var. echinoides</i> probably) (as a tall shrub at 13-16% cover) and <i>Quercus vacciniifolia</i> (23-33% cover) always are dominant. <i>Arctostaphylos nevadensis</i> (5-17%), <i>Vaccinium virgatum (= Vaccinium parviflorum)</i> (8%) are also present in all but a few stands. Other shrubs, including <i>Mahonia repens, Frangula californica (= Rhamnus californicus), Garrya buxifolia</i>, and <i>Amelanchier alnifolia</i> can also be found. Forbs are minor components of these stands, with <i>Xerophyllum tenax</i> (3-7%), <i>Pyrola</i> spp. (1%), and <i>Whipplea modesta</i> (3%) usually present.  Accession Code: VB.CC.32812.CEGL003449 Plot-observations of this Community Concept: 0
