CEGL000348 Abies magnifica var. shastensis / Carex inops ssp. inops Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Shasta Red Fir / Long-stolon Sedge Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is a productive, mostly closed-canopy subalpine or montane forest. It is documented in the Southern Cascades of Oregon and exists on all aspects and slopes 5-30% at elevations of 1740-2040 m (5700-6700 feet). Parent materials are andesite and basalt under loamy soils with many rocks. The tree canopy is dominated by Abies magnifica var. shastensis. There may be trace amounts of Pinus monticola and Tsuga mertensiana. A sparse understory is typified by Carex inops ssp. inops and Chimaphila umbellata except in open stands where a shrub-form of Chrysolepis chrysophylla may dominate, especially at disturbed sites. This association is similar to ~Abies magnifica var. shastensis / Vaccinium membranaceum / Chimaphila umbellata Forest (CEGL000037)$$ except for the absence of Vaccinium spp.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Only 6 plots restricted to the Winema National Forest''s Klamath District were used to describe this community. Patches of Chrysolepis chrysophylla can dominate sites with only a few individual trees and thus could be considered a separate (chaparral) community. Hopkins (1979a) refers to this type as the Shasta Red Fir / Long-Stolon Sedge association (Abies x shastensis / Carex pensylvanica).

Floristics: This is a productive, mostly closed-canopy subalpine or montane forest. The tree canopy is dominated by Abies magnifica var. shastensis (= Abies x shastensis) with 10-70% cover. There may be trace amounts of Pinus monticola and Tsuga mertensiana. A sparse understory is typified by Carex inops ssp. inops (0-10%) and Chimaphila umbellata (1-10%) except in open stands where a shrub-form of Chrysolepis chrysophylla (= Castanopsis chrysophylla) may dominate, especially at disturbed sites.

Environmental Description: It is documented in the Southern Cascades of Oregon and exists on all aspects and slopes 5-30% at elevations of 1740-2040 m (5700-6700 feet). Parent materials are andesite and basalt under loamy soils with many rocks.
Geographic Range: In Oregon, this type is restricted to extreme southern Cascades. It could possibly occur in the southeastern portion of Oregon''s Klamath-Siskiyou region or the northern Modoc Plateau in California.
