Description:
This alliance includes evergreen woodlands dominated by ~Juniperus ashei$, occurring in the Ozarks of Arkansas and Missouri, the Arbuckle Mountains of Oklahoma, and in the Edwards Plateau of Texas. In Texas associated species include evergreen oaks, ~Quercus fusiformis, Quercus vaseyana (= Quercus pungens var. vaseyana)$, and deciduous oaks, ~Quercus sinuata var. breviloba$ and ~Quercus buckleyi$, as well as ~Mahonia trifoliolata (= Berberis trifoliolata), Bouteloua curtipendula, Carex planostachys, Celtis laevigata var. reticulata, Diospyros texana, Fraxinus texensis, Lespedeza texana, Nolina texana, Toxicodendron pubescens (= Rhus toxicodendron), Rhus virens, Schizachyrium scoparium$, and ~Yucca rupicola$. In the Ozarks, the canopy is dominated by ~Juniperus ashei$, although ~Juniperus virginiana$ may be present, and ~Quercus muehlenbergii$ and ~Fraxinus quadrangulata$ may form a minor component. Woodlands in the Arbuckle Mountains of Oklahoma have a grassy understory dominated by ~Schizachyrium scoparium$. Woodlands in this alliance generally occur on calcareous substrates, with shallow, rocky soils, often with much exposed bedrock and lichen coverage. These woodlands occur on dolomite, rimrock bluffs, and as a part of glade complexes (Ozarks), and on slopes with shallow soils over limestone (Edwards Plateau, Arbuckle Mountains). Fire and drought are thought to play an important role in maintaining these woodlands.
