CEGL000177 Pinus monticola / Xerophyllum tenax Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western White Pine / Common Beargrass Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This open woodland association is known from the Applegate Ranger District of the Rogue River National Forest but may also be on neighboring districts in Oregon, and may occur in northern California. Pinus monticola dominates the upper tree canopy. Abies magnifica var. shastensis and Abies lowiana may be present. Xerophyllum tenax clearly dominates the herbaceous layer. Minor associates include Achillea millefolium and Carex spp. Stands occur at elevations of 1860-1980 m (6110-6500 feet) on northeast, east, and south aspects on upper slopes and ridgetops. Slopes range 24-66%. Soil information is lacking.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Only four sample plots were available for this description. Jimerson et al. (1995) found similar communities, but with a significant shrub component, which we assume to be significantly different. Plot data are critical to determine the taxonomic status of this association.

Physiognomy and Structure: No Data Available
Floristics: Pinus monticola dominates the upper tree canopy with 10% cover. Abies magnifica var. shastensis (= Abies x shastensis) and Abies lowiana (= Abies concolor var. lowiana) may be present with 2% and 1% cover, respectively. Xerophyllum tenax clearly dominates the herbaceous layer with about 73% cover. Minor associates include Achillea millefolium (1%) and Carex spp. (2%).

Geographic Range: This association is documented only in the Klamath-Siskiyou region of Oregon, and probably also exists across the stateline into California.
