Name: Pinus jeffreyi / Quercus vacciniifolia - Arctostaphylos nevadensis Woodland
Reference: Western Ecology Working Group of...
Description: This association is currently known from only one area in the Siskiyou Mountains of southwestern Oregon. These woodlands are found at low elevations (averaging 683 m or 2240 feet), on stony (51% cover of surface rock), gravelly (25-33%) serpentine or peridotite soils. The soils are typical, red serpentine clays. Aspects and slopes are variable. This is a woodland, dominated by <i>Pinus jeffreyi</i> (averaging 15% cover), <i>Pseudotsuga menziesii</i> (10% cover), and <i>Pinus attenuata</i> (7% cover). The shrub cover is moderate and variable, with <i>Umbellularia californica</i> at average cover of 18% forming a tall-shrub layer, and <i>Quercus vacciniifolia</i> (22% cover), <i>Arctostaphylos nevadensis</i> (8% cover), <i>Frangula californica (= Rhamnus californica)</i> (4%) at about 1 m tall, and <i>Ceanothus pumilus</i> (3%) as an evergreen shrub ground cover. Forbs are generally present, with <i>Carex</i> spp., <i>Zigadenus micranthus, Aspidotis densa, Galium ambiguum, Lomatium macrocarpum</i>, and <i>Achillea millefolium</i> found in most stands.
