CEGL000257 Abies lowiana - Pinus ponderosa / Carex inops ssp. inops Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sierra White Fir - Ponderosa Pine / Long-stolon Sedge Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This relatively open forest community resides in the southern Cascades of Oregon at elevations of 1770-2135 m (5800-7000 feet). Slopes vary between 6-26% and occur on all aspects. Soils are silty-clay loams over ash and basalt. Pinus ponderosa dominates the tree canopy with lesser cover of Abies lowiana and Populus tremuloides. Important herbaceous species are Poa nervosa, Achillea millefolium, and Carex inops ssp. inops.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This community''s description corresponds to Hopkins'' (1979a) Abies concolor - Pinus ponderosa - Populus tremuloides / Carex pensylvanica association. This community is also somewhat similar to Smith''s (1994b) Pinus jeffreyi - Abies concolor / Poa spp. granite association but has less overall species richness, lacks any Pinus jeffreyi, and Smith''s type does not have any Carex inops ssp. heliophila.

Physiognomy and Structure: No Data Available
Floristics: Pinus ponderosa dominates the tree canopy with cover of 30-50%. Cover of Abies lowiana (= Abies concolor var. lowiana) and Populus tremuloides is 5-10% and 0-30%, respectively. Important herbaceous species are Poa nervosa (5-40%), Achillea millefolium (1-30%), and Carex inops ssp. inops (1-30%).

Environmental Description: This relatively open forest community resides in the southern Cascades of Oregon at elevations of 1770-2135 m (5800-7000 feet). Slopes vary between 6-26% and occur on all aspects. Soils are silty-clay loams over ash and basalt.
Geographic Range: This association is only known from the eastern Cascades of Oregon''s Fremont National Forest. It is possibly also found in the adjacent Warner Mountains of northeastern California.
