A0242 Quercus buckleyi Slope Forest & Woodland Alliance
Type Concept Sentence: This alliance consists of Quercus buckleyi-dominated vegetation of dry-mesic to mesic slopes over calcareous soils of the eastern and southern Edwards Plateau and Lampasas Cutplain in central Texas and in the Arbuckle Mountains in southern Oklahoma.
Common (Translated Scientific) Name: Texas Red Oak Slope Forest & Woodland Alliance
Colloquial Name: Texas Red Oak Slope Forest & Woodland
Hierarchy Level: Alliance
Type Concept: This alliance is characterized by Quercus buckleyi. Associated canopy species include Ulmus crassifolia, Celtis laevigata var. laevigata, Celtis laevigata var. texana, Quercus fusiformis, Quercus muehlenbergii, Prunus serotina var. eximia, and Fraxinus albicans. It is predominantly deciduous, but may occur in mixed stands with lower cover of evergreen oaks and junipers. This alliance occurs in dissected terrain on dry-mesic to mesic limestone slopes in the eastern and southern Edwards Plateau and Lampasas Cutplain in central Texas and in the Arbuckle Mountains in southern Oklahoma. It may cover low hills, but often occupies protected mid to lower slopes in fairly dissected terrain. The underlying substrate is limestone and soils are calcareous.
Diagnostic Characteristics: This alliance consists of Quercus buckleyi-dominated vegetation of dry-mesic to mesic slopes over calcareous soils of the eastern and southern Edwards Plateau and Lampasas Cutplain in central Texas and in the Arbuckle Mountains in southern Oklahoma.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: There may be undescribed associations related to this alliance. More work is needed to determine if the proposed alliances in ~Balconian Dry-Mesic Hardwood Forest Group (G028)$$ are valid. More information is needed to flesh out detailed floristic, environment, and range of this alliance.

Floristics: This alliance consists of Quercus buckleyi-dominated vegetation. Canopy cover ranges from closed to more open. Associated species include Ulmus crassifolia, Celtis laevigata var. laevigata, Celtis laevigata var. texana, Celtis laevigata var. reticulata, Quercus fusiformis, Quercus muehlenbergii, Quercus sinuata var. breviloba, Juniperus ashei, Prunus serotina var. eximia, and Fraxinus albicans (= Fraxinus texensis).
Dynamics: The landscape setting of this alliance, mid to lower slopes in fairly dissected terrain, likely provides some protection from fires which may originate in the surrounding more level uplands.
Environmental Description: This alliance consists of Quercus buckleyi-dominated vegetation of dry-mesic to mesic slopes over calcareous soils. On the Edwards Plateau of Texas, adjacent to Quercus buckleyi slopes on deeper soils over more gentle terrain are Quercus fusiformis woodlands, while Juniperus ashei woodlands occupy the more xeric slopes. Floodplains below Quercus buckleyi forests of the Edwards Plateau are typically dominated by Celtis laevigata, Ulmus americana, Carya illinoinensis, or Quercus fusiformis.
Geographic Range: This alliance occurs on the eastern and southern Edwards Plateau and Lampasas Cutplain, in central Texas, and the Arbuckle Mountains of Oklahoma. It may also be found in the Mexican state of Coahuila.
