CEGL000244 Abies concolor - Pseudotsuga menziesii / Carex siccata Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: White Fir - Douglas-fir / Dry-spike Sedge Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This plant association is known only from a 370-m elevational band near the summits of mountains in two small mountain ranges in southeastern Arizona, the Pinaleno and Santa Catalina mountains. This high-elevation forest is codominated by Abies concolor and Pseudotsuga menziesii with infrequent Abies lasiocarpa. Shrub cover is usually low, but Acer glabrum can be common on moister sites. The ground is covered by a dense sod dominated by Carex siccata often with Bromus ciliatus var. richardsonii, Poa pratensis, Carex rossii. Common forbs include Achillea millefolium var. occidentalis, Campanula rotundifolia, Fragaria virginiana ssp. glauca, Geranium richardsonii, Hymenoxys hoopesii, Lathyrus lanszwertii var. leucanthus, Pteridium aquilinum, Pseudocymopterus montanus, Senecio wootonii, and Vicia americana.
Diagnostic Characteristics: Abies concolor and Pseudotsuga menziesii codominate the overstory, and Pinus ponderosa and Pinus strobiformis are minor seral associates. Picea engelmannii is absent or accidental. The shrub layer usually has <5% cover. Forbs are luxuriant (>50% cover) with Carex siccata having upward of 80% coverage.

Floristics: This high-elevation forest is codominated by Abies concolor and Pseudotsuga menziesii with infrequent Abies lasiocarpa. Shrub cover is usually low, but Acer glabrum can be common on moister sites. The ground is covered by a dense sod dominated by Carex siccata (= Carex foenea) often with Bromus ciliatus var. richardsonii (= Bromus richardsonii), Poa pratensis, Carex rossii. Common forbs include Achillea millefolium var. occidentalis (= Achillea lanulosa), Campanula rotundifolia, Fragaria virginiana ssp. glauca (= Fragaria ovalis), Geranium richardsonii, Hymenoxys hoopesii (= Helenium hoopesii), Lathyrus lanszwertii var. leucanthus (= Lathyrus lanszwertii var. arizonicus), Pteridium aquilinum, Pseudocymopterus montanus, Senecio wootonii, and Vicia americana.
Dynamics: Presence of mature aspen in a major seral role indicates that stand-replacement fires have been a part of their ecology.
Environmental Description: This association is known only from the Pinaleno (Graham) Mountains in Arizona at elevations above 3050 m (10,000 feet) on south-facing slopes and ridgetops and borders of cienegas.
Geographic Range: This plant association is known only from a 370-m elevational band near the summits of mountains in two small mountain ranges in southeastern Arizona, the Pinaleno and Santa Catalina mountains.
