Description:
This association is found on limestone uplands characterized by shallow, rocky "Redlands" soils in the Lampasas Cutplain and other areas of the Edwards Plateau in Texas. The canopy is dominated by Quercus stellata (post oak). Ulmus crassifolia (cedar elm) may codominate and occasionally be the canopy dominant. Other canopy species include Quercus marilandica (blackjack oak), Quercus fusiformis (plateau oak), and Fraxinus texensis (Texas ash). Without fire, Juniperus ashei will increase in importance and stature, eventually occupying part of the canopy with the oaks and presenting greater canopy closure. In intermediate stages, an oak canopy will overtop a subcanopy of Juniperus ashei (Ashe's juniper). Shrubs include Forestiera pubescens (stretchberry), Toxicodendron radicans (eastern poison ivy), Rhus lanceolata (prairie sumac), Ilex decidua (possumhaw), Lonicera albiflora (western white honeysuckle), Sideroxylon lanuginosum (gum bully), Cercis canadensis (eastern redbud), and Viburnum rufidulum (rusty blackhaw). Woody cover can vary greatly, with some examples being very open with few shrubs and other examples with cover approaching that of a forest. Drier, rockier, or more frequently burned examples will tend to exhibit an oak woodland physiognomy. Herbaceous openings may contain Schizachyrium scoparium (little bluestem), Aristida purpurea (purple threeawn), Sorghastrum nutans (Indiangrass), Bouteloua curtipendula (sideoats grama), Bouteloua rigidiseta (Texas grama), Nassella leucotricha (Texas tussockgrass), Schedonnardus paniculatus (tumblegrass), Carex muehlenbergii (Muhlenberg's sedge), and Carex planostachys (cedar sedge). Forb cover is usually low but may include Vernonia baldwinii (Baldwin's ironweed), Croton monanthogynus (prairie tea), Tragia ramosa (branched noseburn), Symphyotrichum drummondii (Drummond's aster), Ruellia humilis (fringeleaf wild petunia), and Vernonia lindheimeri (woolly ironweed). In degraded examples, the ground layer may have a high cover of the invasive grasses Bothriochloa ischaemum (yellow bluestem) and Bromus japonicus (Japanese brome).
