Hierarchy Level: Association
Type Concept: This community is known to occur on the Klamath Ranger District of the Winema National Forest in Oregon. It is typically found between 1680-1980 m (5500-6500 feet) on low-gradient slopes (1-20%) of all aspects. Soils are rocky coarse loams over andesite, basalt, and glacial till. Pinus contorta var. latifolia dominates (30-70% cover). In some stands Tsuga mertensiana supports up to 5% cover. The shrub layer can be well-developed when dominated by Vaccinium scoparium (0-70% cover) and Arctostaphylos nevadensis (0-10% cover). The most extensive cover of Vaccinium scoparium is on deeper soiled sites, while Arctostaphylos nevadensis thrives best in rocky stands. The herbaceous layer often exhibits Vaccinium membranaceum, Carex inops ssp. inops, Phlox diffusa, and Lupinus andersonii, but all are very limited in cover. The rocky, well-drained pumice soils are best for Pinus contorta and, in concert with fire, limit Tsuga mertensiana.

Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is similar to ~Pinus contorta / Vaccinium scoparium / Calamagrostis rubescens Forest (CEGL000174)$$ and may represent a phase that tends to prefer rockier but well-drained pumice soils as indicated by Carex inops ssp. inops and Phlox diffusa. It is not otherwise easily distinguished.
