Name: Quercus douglasii / Bromus sp. - Daucus pusillus Woodland Reference: Western Ecology Working Group of... 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 xeric to dry-mesic environments at low elevations (700-1160 m [2300-3800 feet]) on the mid to high portions of southeast- to northwest-facing slopes that are variable in steepness (gentle to steep). Slopes tend to be linear to undulating. Soils are moderately well-developed with textures ranging from sandy loam to clay loam from metamorphic parent material. The soils at these sites tend to be somewhat poorly drained to well-drained. Fire in this association is common but usually is not extensive. Litter cover ranges from 45-95% but tends to be 80-90%. Invasion from exotics species is common at this association with impact levels of low to high. This association forms an open to intermittent tree layer dominated by <i>Quercus douglasii</i>. The understory is continuous with predominantly <i>Bromus</i> sp. <i>(Bromus hordeaceus, Bromus arenarius</i>, and <i>Bromus diandrus</i>), <i>Daucus pusillus, Avena barbata, Galium parisiense, Lactuca serriola</i>, and a large variety of other herbs and grasses. Often common is <i>Hypochaeris glabra</i>. <i>Trifolium microcephalum</i> and <i>Trifolium wormskioldii</i> are sometimes common. <i>Daucus pusillus, Castilleja densiflora, Silene gallica, Torilis arvensis, Brodiaea elegans, Vulpia myuros, Pinus sabiniana, Clarkia purpurea, Gilia capitata, Trifolium ciliolatum, Erodium cicutarium, Lupinus bicolor, Pellaea mucronata</i>, and <i>Quercus wislizeni</i> are often present contributing to minor cover. <i>Perideridia bacigalupii</i> is a rare species that may be contributing to minor cover in this association.  Accession Code: VB.CC.31140.CEGL008645 Plot-observations of this Community Concept: 0
