CEGL000453 Pseudotsuga menziesii / Quercus hypoleucoides Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir / Silverleaf Oak Forest
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 Chiricahua, Pinaleno and Santa Catalina mountains, and occasionally along the rim of the Nantanes Plateau. It is also present in the Mogollon Mountains in New Mexico. Stands typically occur at elevations ranging from 2010-2350 m (6600-7700 feet) on northerly to east-facing, mid to upper slopes. Pseudotsuga menziesii dominates the overstory with Pinus ponderosa as a major seral or, in some instances, a co-climax dominant. Abies concolor is absent or accidental. Juniperus deppeana is common as a subcanopy tree or shrub. Undergrowth is characterized by Madrean species, with Quercus hypoleucoides ranging from well-represented to abundant. Quercus arizonica and Quercus rugosa are common to well-represented but are subordinate to Quercus hypoleucoides. Other shrubs include Ceanothus fendleri, Cercocarpus montanus, and Garrya wrightii. The robust grass Muhlenbergia longiligula is well-represented and typically dominates the ground cover. Bromus ciliatus var. richardsonii, Carex geophila, Koeleria macrantha, and Poa fendleriana can also be present. Forbs are poorly represented; the most constant species are Comandra umbellata, Ageratina herbacea, Mirabilis comata, and Packera neomexicana.
Diagnostic Characteristics: Oaks are well-represented and dominated by Quercus hypoleucoides. Pseudotsuga menziesii is a dominant tree at late succession, often codominant with Pinus ponderosa.

Floristics: Pseudotsuga menziesii dominates the overstory with Pinus ponderosa as a major seral or, in some instances, a co-climax dominant. Abies concolor is absent or accidental.

Quercus arizonica and Quercus rugosa are common to well-represented but are subordinate to Quercus hypoleucoides. Other shrubs include Ceanothus fendleri, Cercocarpus montanus, and Garrya wrightii. The robust grass Muhlenbergia longiligula is well-represented and typically dominates the ground cover. Bromus ciliatus var. richardsonii (= Bromus richardsonii), Carex geophila, Koeleria macrantha (= Koeleria pyramidata), and Poa fendleriana can also be present. Forbs are poorly represented; the most constant species are Comandra umbellata, Ageratina herbacea (= Eupatorium herbaceum), Mirabilis comata (= Oxybaphus comatus), and Packera neomexicana (= Senecio neomexicanus).
Dynamics: Oak sprouting is prolific and rapid after a fire. Quercus hypoleucoides woodland may be established after severe fires.

Geographic Range: This association is restricted to Apache Highlands (Ecoregion 22) of southwestern New Mexico, southern Arizona, and northern Mexico. It is specifically known from the Chiricahua, Pinaleno and Santa Catalina mountains, and occasionally along the rim of the Nantanes Plateau. It is also present in the Mogollon Mountains in New Mexico.
