CEGL004172 Juniperus ashei - Quercus buckleyi Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Ashe''s Juniper - Texas Red Oak Woodland
Colloquial Name: Edwards Plateau Ashe''s Juniper - Texas Red Oak Woodland
Hierarchy Level: Association
Type Concept: These woodlands occur over rocky, shallow soils on dry to xeric limestone slopes in the Edwards Plateau and Lampasas Cutplain of Texas. The association is dominated by Juniperus ashei with high cover of Quercus buckleyi. Total cover varies by exposure but can approach that of a forest. Quercus fusiformis may be present, especially along toeslopes adjacent to deeper soils. Other woody species include Fraxinus albicans, which may sometimes be a codominant, Quercus muehlenbergii, Quercus sinuata var. breviloba, Toxicodendron radicans, Rhus trilobata, Lonicera albiflora, Frangula caroliniana, Forestiera pubescens, Viburnum rufidulum, Ilex decidua, Sideroxylon lanuginosum, and Ulmus crassifolia. Herbaceous cover is sparse and may include Carex planostachys, Salvia roemeriana, Nolina spp., Tragia brevispica, Tragia ramosa, Lespedeza texana, Schizachyrium scoparium, Bouteloua hirsuta, Sporobolus compositus, Stillingia texana, Galactia volubilis, Brickellia cylindracea and Matelea spp.

Classification Comments: Restricted to Texas. This association is distinguished from ~Quercus buckleyi - Fraxinus albicans - Juniperus ashei Forest (CEGL002135)$$ by the dominance of Juniperus ashei over the deciduous species. It is generally found on more exposed and more xeric slopes, and total canopy cover may be lower. Both associations may also occur on the same slope, with CEGL002135 being found on more sheltered portions of the slope.

Floristics: The association is dominated by Juniperus ashei with high cover of Quercus buckleyi. Total cover varies by exposure but can approach that of a forest. Quercus fusiformis may be present, especially along toeslopes adjacent to deeper soils. Other woody species include Fraxinus albicans (= Fraxinus texensis) (which may sometimes be a codominant), Quercus muehlenbergii, Quercus sinuata var. breviloba, Toxicodendron radicans, Rhus trilobata, Lonicera albiflora, Frangula caroliniana, Forestiera pubescens, Viburnum rufidulum, Ilex decidua, Sideroxylon lanuginosum, and Ulmus crassifolia. Herbaceous cover is sparse and may include Carex planostachys, Salvia roemeriana, Nolina spp., Tragia brevispica, Tragia ramosa, Lespedeza texana, Schizachyrium scoparium, Bouteloua hirsuta, Sporobolus compositus, Stillingia texana, Galactia volubilis, Brickellia cylindracea, and Matelea spp.
Dynamics: Because of extremely low fine-fuel loads, fire is rare. High-intensity crownfires will kill most Juniperus ashei, but Quercus buckleyi and most other deciduous species will rapidly resprout and form a dense woodland. Under these competitive conditions, return of Juniperus ashei as a canopy species may take decades.
Environmental Description: These woodlands occur over rocky, shallow soils on limestone slopes in the Edwards Plateau and Lampasas Cutplain of Texas.
Geographic Range: This community occurs in the Edwards Plateau and Lampasas Cutplain of central Texas.
