CEGL004453 Quercus sinuata var. breviloba Scrub
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: White Shin Oak Scrub
Colloquial Name: White Shin Oak Scrub
Hierarchy Level: Association
Type Concept: This association is found in the Arbuckle Mountains of Oklahoma (Garvin, Johnston, and Murray counties) and the Lampasas Cutplain and Edwards Plateau of central Texas, where it occurs on shallow soils over limestone mesatops, upper slopes and escarpments. Quercus sinuata var. breviloba is dominant. Other characteristic species may include, within their respective ranges, Bouteloua curtipendula, Bouteloua hirsuta, Bouteloua rigidiseta, Hedeoma drummondii, Hilaria belangeri, Cercis canadensis var. texensis, Engelmannia peristenia, Forestiera pubescens, Fraxinus albicans, Sideroxylon lanuginosum, Ilex decidua, Celtis laevigata var. reticulata, Ulmus crassifolia, Sophora secundiflora, Quercus buckleyi, Polygala lindheimeri, Ptelea trifoliata, Rhus lanceolata, Rhus virens var. virens, Rhus trilobata var. trilobata, Schizachyrium scoparium, and, in more mesic areas, Toxicodendron radicans ssp. eximium, Ungnadia speciosa, Sporobolus vaginiflorus var. ozarkanus, Carex planostachys, Lespedeza texana, and Opuntia engelmannii. Herbaceous cover is usually low beneath shrubs and high between clumps of shrubs. This community is favored by fire, other disturbances, and harsh environmental conditions. It is considered good habitat for the endangered black-capped vireo (Vireo atricapilla) which prefers an open, primarily deciduous shrubland with dense foliage extending to ground level.

Floristics: The shrub canopy is dominated by Quercus sinuata var. breviloba. Other woody components may include Forestiera pubescens, Eysenhardtia texana, Cercis canadensis var. texensis, Fraxinus albicans (= Fraxinus texensis), Ptelea trifoliata, Quercus buckleyi, Rhus lanceolata, Rhus virens var. virens, Rhus trilobata var. trilobata (= Rhus aromatica var. flabelliformis), and Mahonia trifoliolata (= Berberis trifoliolata). Grassy or rocky openings may include Bouteloua curtipendula, Bouteloua hirsuta, Bouteloua rigidiseta, Hilaria belangeri, Schizachyrium scoparium, Hedeoma drummondii, Polygala lindheimeri, and Engelmannia peristenia (= Engelmannia pinnatifida).
Dynamics: This community is maintained by xeric conditions and thin soils over rocky limestone substrates and as a disclimax community by periodic fires. It may have persisted on the landscape in a shifting mosaic with earlier and later seral stages. Vegetation similar to this natural type may result from the encroachment of woody plants into grassland areas.
Environmental Description: This community occupies mesa tops, upper slopes and escarpment edges with thin soils over limestone outcrops where it forms dense shrubby thickets usually occurring in a patchy mosaic with open, grassy or rocky areas and occasionally scattered small trees.
Geographic Range: This association is restricted to limestone outcrops in southern Oklahoma and central Texas.
