CEGL002135 Quercus buckleyi - Fraxinus albicans - Juniperus ashei Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Texas Red Oak - Texas Ash - Ashe''s Juniper Forest
Colloquial Name: Edwards Plateau Texas Red Oak - Ashe''s Juniper Forest
Hierarchy Level: Association
Type Concept: This association consists of Quercus buckleyi-dominated vegetation of dry-mesic/mesic slopes over calcareous soils of the eastern and southern Edwards Plateau and Lampasas Cutplain, in central Texas. Stands are often clearly dominated by Quercus buckleyi. Another dominant and characteristic canopy species is Fraxinus albicans. Total cover of Juniperus ashei is variable but typically less than 40%, and though a characteristic component of the canopy, most of this cover is in the midstory. Other associated canopy species include Ulmus crassifolia, Celtis laevigata var. laevigata, Celtis laevigata var. texana, Celtis laevigata var. reticulata, Quercus fusiformis, Quercus muehlenbergii, Quercus sinuata var. breviloba, and Prunus serotina var. eximia. Herbaceous components may include Carex planostachys, Lespedeza texana, Carex edwardsiana, Tragia ramosa, Brickellia cylindracea, Symphyotrichum drummondii, Nolina texana, Commelina erecta, and Passiflora lutea. These forests (typically with a closed canopy, although sometimes with open canopies) lack Quercus laceyi, which is more characteristic of the Balcones portion of the western Edwards Plateau.

Classification Comments: The taxon properly called Quercus buckleyi has been called Quercus texana, Quercus shumardii var. texana, and Quercus shumardii var. microcarpa, but Nixon & Dorr (1985. Taxon 34: 225) concluded that these names were misapplied and named the species in honor of State Geologist of Texas Samuel Botsford Buckley (1809-1884).

Floristics: Stands are often clearly dominated by Quercus buckleyi. Another dominant and characteristic canopy species is Fraxinus albicans (= Fraxinus texensis). Total cover of Juniperus ashei is variable but typically less than 40%, and though a characteristic component of the canopy, most of this cover is in the midstory. Other associated canopy species include Ulmus crassifolia, Celtis laevigata var. laevigata, Celtis laevigata var. reticulata, Quercus fusiformis, Quercus muehlenbergii, and Prunus serotina var. eximia. The overstory may occasionally include Juglans major at the bottom of the slope near and adjacent to creeks. Common shrubs include Ilex decidua and Viburnum rufidulum. Croton alabamensis and Frangula caroliniana may occur below midslope, and Quercus sinuata may occur in areas near the upper slope. Herbaceous components may include Carex planostachys, Lespedeza texana, Carex edwardsiana, Tragia ramosa, Brickellia cylindracea, Symphyotrichum drummondii (= Aster drummondii), Nolina texana, Commelina erecta, and Passiflora lutea.
Dynamics: No Data Available
Environmental Description: This association occurs on dry-mesic/mesic limestone slopes in the eastern and southern Edwards Plateau and Lampasas Cutplain, in central Texas. In addition to occurring on slopes, at Fort Hood, Texas, this or similar vegetation also occurs along low-gradient, ephemeral or intermittent creeks or draws in more level uplands.
Geographic Range: This association occurs in the eastern and southern Edwards Plateau and Lampasas Cutplain in central Texas.
