This chinquapin oak - mixed oak forest association is found in the inner Nashville Basin of central Tennessee and related areas of the Interior Low Plateau of Kentucky, Illinois and Indiana, and in Virginia and marginally into the southern limestone/dolomite valleys of northwestern Georgia. Stands include dry to subxeric forests of flat to rolling topography. Some stands in the Shawnee Hills may have a southerly exposure with thin loess-derived soils. The vegetation is dominated by a mixture of <i>Quercus muehlenbergii, Quercus falcata, Quercus shumardii</i>, and <i>Quercus stellata</i>, with <i>Quercus velutina</i> in smaller amounts. <i>Carya carolinae-septentrionalis, Carya glabra</i>, and <i>Fraxinus americana</i> may also be present in the canopy, which is typically somewhat open. The relatively open subcanopy contains <i>Acer saccharum, Fraxinus americana, Fraxinus quadrangulata, Ulmus alata, Ulmus serotina</i>, and <i>Celtis laevigata</i>. <i>Juniperus virginiana var. virginiana, Viburnum rufidulum, Frangula caroliniana, Cercis canadensis, Ostrya virginiana, Sideroxylon lycioides, Prunus americana</i>, and <i>Prunus angustifolia</i> are present as tall shrubs or small trees. Coverage of <i>Juniperus</i> in the subcanopy may be dense in some examples, but this vegetation is treated here rather than as a mixed forest. Low shrubs include <i>Rhus aromatica, Forestiera ligustrina, Viburnum rufidulum, Hypericum frondosum, Ptelea trifoliata</i>, and <i>Symphoricarpos orbiculatus</i>. Herbs present include <i>Andropogon</i> spp., <i>Antennaria plantaginifolia, Symphyotrichum shortii (= Aster shortii), Cheilanthes lanosa, Cunila origanoides, Diarrhena americana, Dichanthelium boscii, Galium circaezans, Heuchera americana, Monarda fistulosa, Schizachyrium scoparium, Scutellaria ovata, Solidago missouriensis, Solidago sphacelata</i>, and <i>Verbesina virginica</i>. A prominent woody vine is <i>Bignonia capreolata</i>. In Tennessee's Nashville Basin, this association is found over Ordovician limestones (Lebanon, Ridley) at about 200 m elevation. This type also includes examples from slopes above limestone cliffs, e.g., bordering the Ohio River in Harrison County (southern Indiana) and possibly adjacent Kentucky (the former CEGL005020), where <i>Quercus muehlenbergii</i> is found with <i>Fraxinus americana</i> and <i>Fraxinus quadrangulata</i>. This specific example is assumed to be compatible with ~<i>Quercus muehlenbergii - Quercus (falcata, shumardii, stellata) / Cercis canadensis / Viburnum rufidulum</i> Forest (CEGL007699)$$. |

This encinal association occurs in southeastern Arizona, southern New Mexico, and possibly Trans-Pecos Texas and adjacent Mexico. Stands occur on gently to moderately sloping alluvial plains, bajadas and canyon bottoms to steep, rocky slopes in canyons, piedmont hills and mountains. Elevation ranges from 1300-1980 m (4270-6500 feet) extending up to 2285 m (7500 feet) on southern to western aspects. Soils are shallow, gravelly or stony sandy loams or sandy clay loams, derived from a mixture of alluvium and colluvium. The vegetation is characterized by an open to moderately dense evergreen tree layer (10-60% cover) dominated by <i>Quercus grisea</i> with a grassy understory. The tree canopy is typically 3-5 m tall and >5 m tall in bottomland stands. Stands range from tree savanna to open woodland and moderately dense woodland at higher elevations and in canyon bottoms. <i>Quercus arizonica, Quercus emoryi, Quercus gravesii, Quercus oblongifolia, Prosopis</i> spp., <i>Juniperus deppeana, Juniperus monosperma</i>, and occasional <i>Pinus cembroides, Pinus discolor</i>, or <i>Pinus edulis</i> may be present in tree canopy but generally not codominant. There may be a sparse to moderately dense shrub layer, but graminoids dominate the understory. Shrubs and succulents present may include <i>Agave palmeri, Acacia constricta, Arctostaphylos pungens, Brickellia</i> spp., <i>Cercocarpus montanus, Dasylirion wheeleri, Dodonaea viscosa, Ericameria laricifolia, Eriogonum wrightii, Erythrina flabelliformis, Eysenhardtia orthocarpa, Garrya wrightii, Mimosa aculeaticarpa var. biuncifera, Mimosa dysocarpa, Nolina microcarpa, Opuntia engelmannii, Opuntia phaeacantha, Opuntia spinosior, Quercus turbinella, Rhus trilobata, Yucca baccata</i>, and <i>Yucca schottii</i>. The graminoid layer is moderately dense to dense (25-80% cover) and typically dominated by medium-tall bunchgrasses such as <i>Bouteloua curtipendula, Schizachyrium cirratum (= Andropogon cirratus)</i>, or <i>Muhlenbergia emersleyi</i>, but it can be very diverse. Other common graminoids may include <i>Aristida schiedeana var. orcuttiana (= Aristida orcuttiana), Bouteloua chondrosioides, Bouteloua eriopoda, Bouteloua gracilis, Bouteloua hirsuta, Bothriochloa barbinodis, Eragrostis intermedia, Leptochloa dubia, Muhlenbergia longiligula</i>, and <i>Poa fendleriana</i>. The usually sparse, but often diverse, forb layer may include <i>Artemisia ludoviciana, Boerhavia intermedia, Commelina erecta, Chenopodium</i> spp., <i>Datura wrightii, Ipomoea cristulata, Geranium caespitosum, Phaseolus</i> spp., and many others. Diagnostic of this association is the dominance of <i>Quercus grisea</i> in the tree canopy with at least 5% cover and a grass-dominated understory. |
