CEGL000872 Pinus ponderosa / Quercus hypoleucoides Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Ponderosa Pine / Silverleaf 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, Trans-Pecos of Texas, and northern Mexico. It is specifically known from the Santa Catalina, Pinal, Santa Rita, Galiuro, Pinaleno, Chiricahua, Huachuca, Davis, and Peloncillo mountains. It is occasional along the southern edge of the Nantanes Plateau and uncommon along the eastern Mogollon Rim in the central highlands of Arizona. Stands typically occur in the mid-elevation range of ~Pinus arizonica - Pinus engelmannii - Pinus leiophylla Woodland Alliance (A3112)$$ at 1740-2165 m (5700-7100 feet). Slopes are steep to very steep with variable aspects, but generally the sites are mild and dry. Soils are predominantly Udic Haplustalfs, Udic Ustochrepts, and Lithic Ustochrepts derived from granite, rhyolite, or their metamorphic derivatives. Pinus ponderosa is the overstory dominant. Pinus strobiformis is occasionally a codominant. Pseudotsuga menziesii, Pinus leiophylla, and Pinus engelmannii are absent or accidental. Juniperus deppeana is often present as a minor climax species in the subcanopy. Quercus hypoleucoides is dominant in the undergrowth, reaching coverage as high as 60%. Quercus arizonica can be well-represented, but it is either not dominant or is clearly successional; Quercus rugosa can be present but usually is poorly represented and never dominant. Other common shrubs are Nolina microcarpa, Arbutus arizonica, Ceanothus fendleri, and Garrya wrightii. Muhlenbergia longiligula is common and typically dominates the otherwise sparse herb layer. Muhlenbergia straminea may be present but is not dominant. The most constant forbs are Hedeoma hyssopifolia, Pseudocymopterus montanus, and Comandra umbellata. In Texas, this community is known from the Davis Mountains.
Diagnostic Characteristics: Quercus hypoleucoides is well-represented (>5%). Pinus ponderosa is the dominant overstory species, and Pseudotsuga menziesii and Abies concolor are absent or accidental.

Other common shrubs are Nolina microcarpa, Arbutus arizonica, Ceanothus fendleri, and Garrya wrightii. Muhlenbergia longiligula is common and typically dominates the otherwise sparse herb layer. Muhlenbergia straminea (= Muhlenbergia virescens) may be present but is not dominant. The most constant forbs are Hedeoma hyssopifolia, Pseudocymopterus montanus, and Comandra umbellata.
Dynamics: Oak sprouting is prolific and rapid after a fire.
