Name: Pinus contorta var. murrayana / Sparse Understory Woodland
Reference: NatureServe Biotics 2019
Description: Stands of this woodland are found throughout the central and southern Sierra Nevada. Stands of this woodland are found at mid to upper elevations (2255-3050 m [7400-10,000 feet]) on all aspects. This association is found on gentle to moderate slopes that are 5-30%. This association is often on lower slopes and benches; however, a high portion is also on broad somewhat rounded ridgetops and a few occur on midslopes. Bare ground and surface gravel are higher at this association and litter cover is lower compared to other nearby associations. Microrelief is usually uniformly smooth; however, sites are occasionally hummocky due to large surface rocks. Soils are typically sandy and derived from granite, however, are formed from pumice cinders and ash near Mammoth Mountain. Soil depths are between 63 and 89 cm (25-35 inches). Coarse fragments are relatively low and drainage is usually excessive. Stands are open woodlands with a scattered understory of herbs. Tree cover is scattered and in patches. The overstory is characterized by open <i>Pinus contorta</i> usually with scattered <i>Abies magnifica</i>. The shrub layer is essentially missing or occurs at very low levels. The herbaceous layer comprises of <i>Cistanthe umbellata var. caudicifera, Pedicularis semibarbata, Arabis platysperma, Eriogonum nudum, Gayophytum eriospermum, Elymus elymoides ssp. californicus</i>, and <i>Achnatherum occidentale ssp. californicum</i>. Regeneration is dominated by <i>Abies magnifica</i>; however, <i>Pinus contorta</i> is also present.
