CEGL000869 Pinus ponderosa / Quercus emoryi Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Ponderosa Pine / Emory Oak Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This Pinus ponderosa woodland occurs at relatively low elevations in the mountains of Trans-Pecos Texas. Quercus emoryi dominates the oak understory, often with Quercus grisea as well. Grasses include Bouteloua curtipendula, Bouteloua gracilis, Bothriochloa barbinodis, and others. It may grade upslope to ~Pinus ponderosa / Quercus grisea Woodland (CEGL000871)$$. In Texas, this community is known from the Davis Mountains.
Diagnostic Characteristics: Quercus emoryi is well-represented (>5% canopy coverage). Located primarily in drainages and lower slopes. Quercus gambelii and Quercus hypoleucoides are absent or poorly represented. Juniperus scopulorum is absent or accidental.

Floristics: Pinus ponderosa dominates the canopy, and Quercus emoryi dominates the oak understory, often with Quercus grisea as well. Grasses include Bouteloua curtipendula, Bouteloua gracilis, Bothriochloa barbinodis (= var. barbinodis), and others.
Dynamics: Oak sprouting may be prolific and rapid after a fire. If manzanita is present in the stand, areas experiencing severe fires can establish a chaparral shrub community.
Environmental Description: This pine woodland is found most commonly on mid to lower slopes and ravine bottoms and is most differentiated along drainages with granitic soils (Udic Ustochrepts). Elevation ranges from 1615 to 2100 m (5300-6900 feet).
Geographic Range: This woodland association occurs south of the Mogollon Rim, in southwestern New Mexico, and southern Arizona. It is more likely found in the Central Highlands, along the base of the Mogollon Rim and the Nantanes Plateau, and it is uncommon in the basin ranges and plateau regions of southern Arizona. It also occurs at relatively low elevations in the mountains of Trans-Pecos Texas.
