Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sierra Lodgepole Pine / Mountain Pride Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: 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. This woodland is found at high elevations (2620-2955 m [8600-9700 feet]) on moderately steep to somewhat steep slopes (10-20°) that are generally convex in shape. Aspect varies from northeast to west but tends to be west-facing. These sites are usually shallow, well-drained soils formed on granitic parent material. Soils are generally poorly developed and rocky with textures ranging from rocky and gravelly to rocky, gravelly, sandy loam. Fire is common at this association. Stands are characterized by an open overstory tree layer dominated by Pinus contorta. Rarely, Pinus monticola is found contributing minor cover to the tree layer. The herb layer is also open. Penstemon newberryi is constant in the understory based on field verification. However no supporting herbaceous data are available from Wieslander plots. Juncus sp. (probably mostly Juncus parryi) is often present and Carex sp. is occasionally present. A variety of other species may be found contributing to minor cover in the understory shrub and herbaceous layers including Arctostaphylos nevadensis, Chrysolepis sempervirens, Quercus vacciniifolia, Antennaria media, Spiraea splendens, Holodiscus discolor, and Eriogonum umbellatum var. umbellatum.
