Name:
Juniperus ashei Ozark Woodland Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance includes evergreen woodlands primarily dominated by <i>Juniperus ashei</i>, occurring in the Ozarks of Arkansas and Missouri, the Arbuckle Mountains of Oklahoma, in the Edwards Plateau of Texas, and in the adjacent Upper West Gulf Coastal Plain of Arkansas. In the Ozarks, the canopy is dominated by <i>Juniperus ashei</i>, although <i>Juniperus virginiana</i> may be present, and <i>Quercus muehlenbergii</i> and <i>Fraxinus quadrangulata</i> may form a minor component. Other associated woody species may include <i>Celtis tenuifolia, Cercis canadensis, Quercus stellata</i>, and <i>Ulmus alata</i>. Some other characteristic plants include <i>Cotinus obovatus, Carex eburnea</i>, and <i>Rudbeckia missouriensis</i>. In Texas, associated species include evergreen oaks <i>Quercus fusiformis, Quercus vaseyana</i>, and deciduous oaks <i>Quercus sinuata var. breviloba</i> and <i>Quercus buckleyi</i>, as well as <i>Bouteloua curtipendula, Carex planostachys, Celtis laevigata var. reticulata, Diospyros texana, Fraxinus albicans, Lespedeza texana, Mahonia trifoliolata, Nolina texana, Rhus virens, Schizachyrium scoparium, Toxicodendron pubescens</i>, and <i>Yucca rupicola</i>. Woodlands in the Arbuckle Mountains of Oklahoma have a grassy understory dominated by <i>Schizachyrium scoparium</i>. Fire, climate and edaphic factors are thought to play important roles in maintaining these woodlands. These woodlands occur on shallow, rocky soils, often with much exposed bedrock and lichen coverage. Habitats include dolomite, on rimrock bluffs, as part of glade complexes (in the Ozarks), on chalk outcrops, and on slopes with shallow soils over limestone (in the Edwards Plateau and Arbuckle Mountains).
