CEGL000312 Abies lasiocarpa / Jamesia americana Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Subalpine Fir / Five-petal Cliffbush Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This high-elevation forest is dominated by Abies lasiocarpa. Picea engelmannii is not present. Pseudotsuga menziesii and Populus tremuloides are major serial species in the forest canopy. Abies concolor may be a minor serial species. Shrub cover is high, dominated by Jamesia americana (diagnostic) with Ribes pinetorum, Rubus idaeus, Sambucus racemosa var. melanocarpa, and Symphoricarpos oreophilus. Herbaceous cover is sparse and patchy, with graminoids essentially absent and forb diversity low. Vicia americana is most common with traces of Aquilegia spp., Galium spp., Pteridium aquilinum, Orthilia secunda, Senecio spp., Viola canadensis, and Woodsia spp. This association is restricted to cold-mesic, steep, talus northern slopes near the summit of Mount Lemmon in the Santa Catalina Mountains in southeastern Arizona.
Diagnostic Characteristics: Abies lasiocarpa dominates the overstory. Shrubs include Jamesia americana and others. Understory has scattered patches of forbs.

Floristics: Thisforest is dominated by Abies lasiocarpa. Picea engelmannii is not present. Pseudotsuga menziesii and Populus tremuloides are major serial species in the forest canopy. Abies concolor may be a minor serial species. Shrub cover is high, dominated by Jamesia americana (diagnostic) with Ribes pinetorum, Rubus idaeus, Sambucus racemosa var. melanocarpa (= Sambucus melanocarpa), and Symphoricarpos oreophilus. Herbaceous cover is sparse and patchy, with graminoids essentially absent and forb diversity low. Vicia americana is most common with traces of Aquilegia spp., Galium spp., Pteridium aquilinum, Orthilia secunda (= Ramischia secunda), Senecio spp., Viola canadensis, and Woodsia spp.
Dynamics: This plant association may be fire-disturbed, probably with long periods between major fire events; however, specific information was not available.
Environmental Description: This association is restricted to cold-mesic, steep, talus northern slopes near the summit of Mount Lemmon above 2650 m (8700 feet) elevation in the Santa Catalina Mountains in southeastern Arizona.
Geographic Range: This association is known only from the high-elevation (2670-2775 m) northern slopes of Mount Lemmon in the Santa Catalina Mountains in southeastern Arizona.
