Common (Translated Scientific) Name: Knobcone Pine / Sticky Whiteleaf Manzanita 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. Stands of this woodland are found at xeric to dry-mesic sites at low elevations (880-1190 m [2900-3900 feet]) on the upper slopes and ridgetops of variable but mostly southeast- to west-facing, gentle to somewhat steep slopes. The shapes of slopes are highly variable. Soils are moderately developed to well-developed with textures ranging from silt loam to clay loam from metamorphic and granitic parent material. Soils are moderately well-drained to well-drained. Litter cover is 70-80%. Disturbance levels can be low to high and include competition from exotics, road/trail construction, and vandalism/litter. Fire is also a common disturbance. This association is dominated by an open layer of Pinus attenuata in the overstory with an often dense understory shrub layer dominated by Arctostaphylos viscida. Often found in the shrub layer are Adenostoma fasciculatum and Chamaebatia foliolosa. Where Arctostaphylos viscida is more open, Chamaebatia foliolosa often becomes an extensive ground cover. Occasionally, present are Pinus ponderosa, Quercus kelloggii, Vulpia myuros, and Arctostaphylos mewukka. Other species that may contribute to cover include Quercus douglasii, Toxicodendron diversilobum, Ceanothus cuneatus, Dichelostemma capitatum, Sanicula bipinnata, and Filago sp. Locally, the ridgetop locations for this association suggest relatively intense fires of moderate frequency are necessary for its maintenance.
