CEGL000822 Pinus leiophylla / Quercus arizonica Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Chihuahuan Pine / Arizona White Oak Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This highly diverse "Madrean" woodland association is restricted to the isolated "sky island" mountain ranges of southwestern New Mexico, southern Arizona, and northern Mexico. It is specifically known from the Peloncillo Mountains in New Mexico, and the Chiricahua, Galiuro and Pinaleno mountains in southern Arizona. There are a few isolated outliers in the central highlands of Arizona (Tonto National Forest and Fort Apache Indian Reservation). Stands typically occur on steep to very steep slopes with northerly aspects at elevations from 1600-2165 m (5250-7100 feet). Soils are shallow (50 cm to bedrock), cobbly, and with low water-holding capacity. Pinus leiophylla forms an open canopy with Pinus cembroides and Juniperus deppeana in the subcanopy. Pinus ponderosa sometimes is present as a climax codominant. The undergrowth is distinctively shrubby and dominated by Quercus arizonica; Quercus hypoleucoides is often abundant but subordinate to Quercus arizonica. Quercus emoryi may also be present, but is usually poorly represented. Along with the evergreen oaks, there are xeric shrubs such as Garrya wrightii, Yucca madrensis, Arctostaphylos pungens, Rhus aromatica, and Nolina microcarpa. Xeric grasses are characteristic and include Schizachyrium cirratum, Aristida schiedeana var. orcuttiana, and Muhlenbergia longiligula. Piptochaetium fimbriatum may be present but poorly represented and not dominant. Forbs are diverse, variable, and scarce in cover; the most constant forbs are Packera neomexicana, Gnaphalium spp., Solidago velutina, Bahia dissecta, and Cheilanthes fendleri.
Diagnostic Characteristics: Pinus leiophyllla is climax. Pinus engelmannii is absent. Quercus arizonica is the dominant oak, especially more dominant than Quercus hypoleucoides.
