CEGL000248 Abies concolor / Juglans major Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: White Fir / Arizona Walnut Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is a montane forested riparian association found in higher elevation drainages along the Mogollon Rim and in the Sierra Ancha of the central highlands of Arizona across to the Mogollon Mountains of southwestern New Mexico, and also in the Sacramento Mountains of south-central New Mexico. It likely occurs in adjacent Mexico. Elevations range from 1950-2440 m (6400-8000 feet), and sites are typically found adjacent to streams on river terraces, or on immediate sideslopes. Soils are usually alluvial Aquents and tend to be silty in a matrix of boulders and rocks. The overstory is characterized by the dominance of Abies concolor, with Pseudotsuga menziesii and Pinus ponderosa as possible minor associates. There is a diverse subcanopy composed of a mixture of Acer negundo, Fraxinus pennsylvanica, Juglans major, or Quercus gambelii. The shrub layer is minor; Mahonia repens is the most common shrub species present. The herb stratum is luxuriant with Fragaria virginiana ssp. glauca, Galium mexicanum ssp. asperrimum, Geranium richardsonii, Lathyrus lanszwertii var. leucanthus, Osmorhiza depauperata, Thalictrum fendleri, Monarda fistulosa var. menthifolia, and Viola canadensis present and usually common.
Diagnostic Characteristics: Overstory is dominated by Abies concolor and a varying mixture of large deciduous trees of which Juglans major is diagnostic. It is restricted to drainages. Pinus strobiformis, Pinus edulis, Juniperus deppeana, Picea pungens, and Populus angustifolia are absent or accidental.

Floristics: The overstory is characterized by the dominance of Abies concolor, with Pseudotsuga menziesii and Pinus ponderosa as possible minor associates. There is a diverse subcanopy composed of a mixture of Acer negundo, Fraxinus pennsylvanica, Juglans major, or Quercus gambelii. The shrub layer is minor; Mahonia repens (= Berberis repens) is the most common shrub species present. The herb stratum is luxuriant with Fragaria virginiana ssp. glauca (= Fragaria ovalis), Galium mexicanum ssp. asperrimum (= Galium asperrimum), Geranium richardsonii, Lathyrus lanszwertii var. leucanthus (= Lathyrus arizonicus), Osmorhiza depauperata, Thalictrum fendleri, Monarda fistulosa var. menthifolia, and Viola canadensis present and usually common.
Dynamics: Juglans major has few adaptations to fire. The montane riparian settings supporting it probably burn infrequently and then erratically. As a disturbance factor, flooding has more consistent effects.

Soils are usually alluvial Aquents and tend to be silty in a matrix of boulders and rocks.
Geographic Range: This association is restricted to the northern Apache Highlands and Arizona-New Mexico Mountains ecoregions in Arizona and New Mexico. It is found in higher elevation drainages along the Mogollon Rim and in the Sierra Ancha of the central highlands of Arizona across to the Mogollon Mountains of southwestern New Mexico, and also in the Sacramento Mountains of south-central New Mexico. It likely occurs in adjacent Mexico.
