CEGL000864 Pinus ponderosa / Muhlenbergia straminea - Festuca arizonica Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Ponderosa Pine / Screwleaf Muhly - Arizona Fescue Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: No Data Available
Diagnostic Characteristics: A mesic Pinus ponderosa woodland, which must have Muhlenbergia straminea and Festuca arizonica. Pseudotsuga menziesii, Pinus strobiformis, and Juniperus osteosperma are absent or accidental.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: In addition to the typic phase, Stuever and Hayden (1997a) identify two other phases: the Gambel oak phase generally has much lower canopy coverage of screwleaf muhly and Arizona fescue; and the blue grama phase may be a secondary successional stage resulting from heavy grazing. This phase is probably much drier than the other phases of this plant association.

Dynamics: Fires occur in this type with moderate frequency and are generally surface fires. Swetnam and Dieterich (1985) found presettlement fire frequencies in the Gila Wilderness ranged from 1 to 22 years with mean fire intervals from 4 to 8 years.
Environmental Description: This association is found on many slopes and aspects at elevations of 2100 to 2800 m (6900-9200 feet).
Geographic Range: This ponderosa pine woodland occurs in central Arizona (generally north of the Mogollon Rim up to the San Francisco Peaks area), and southwestern New Mexico (Gila National Forest).
