CEGL000260 Abies lowiana - Pinus monticola / Ribes viscosissimum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sierra White Fir - Western White Pine / Sticky Currant Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is only known from the Warner Mountains of south-central Oregon and northeastern California. It is found on the mid and upper northerly slopes of moderate (10-30%) steepness. Elevations are between 1980 and 2260 m (6500-7400 feet). Soils are typically rocky loams over basalt or rhyolite parent material. Abies lowiana is usually dominant, but Pinus monticola and Pinus ponderosa are also important in contributing to a mostly closed tree canopy. Ribes viscosissimum is common on most sites, but is occasionally absent. Common understory herbs are Hieracium albiflorum, Poa wheeleri, and Carex inops ssp. heliophila. After fires, Pinus monticola regenerates well, especially at higher elevations.
