Name: Pinus jeffreyi - Abies lowiana Woodland Reference: NatureServe Biotics 2019 Description: This woodland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this woodland are found at mid to high elevations (1875-2530 m [6150-8300 feet]) on flat to steep (0-31°) slopes. Aspect varies; however, it is often southeast, south and southwest. These sites are typically found on poorly developed to well-developed soils with textures ranging from gravel to loam. Soils are well-drained to moderately well-drained and shallow to deep. Fire is common and disturbance levels are usually low at this association. Stands of this woodland are dominated by <i>Pinus jeffreyi</i> and <i>Abies lowiana</i> in the open overstory layer. Other tree species that may be found contributing to significantly less cover include <i>Pinus lambertiana, Abies magnifica, Pinus contorta var. murrayana, Calocedrus decurrens, Quercus kelloggii, Pinus lambertiana, Populus tremuloides</i>, and <i>Juniperus occidentalis</i>. <i>Ceanothus cordulatus</i> and <i>Arctostaphylos patula</i> are often in the understory shrub layer. <i>Chrysolepis sempervirens, Prunus emarginata, Quercus vacciniifolia, Arctostaphylos nevadensis</i>, and <i>Artemisia tridentata</i> may also be present, but in low numbers. <i>Pteridium aquilinum var. pubescens</i> is often in the herb layer. Other herbaceous species may include <i>Gayophytum diffusum ssp. parviflorum, Apocynum androsaemifolium, Kelloggia galioides, Erigeron breweri, Eriogonum marifolium</i>, and <i>Hieracium albiflorum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:36678-{FEC563F6-CF2E-40E0-8C9A-E27A2B006D16} Plot-observations of this Community Concept: 0
