Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Western Soapberry Woodland

Colloquial Name: Soapberry Talus & Dune Woodland

Hierarchy Level:  Association

Type Concept: This is a broadly defined community dominated by Sapindus saponaria var. drummondii. As currently conceived, examples are open woodlands potentially occurring throughout Oklahoma, and possibly Texas as well, but found most commonly in central and western Oklahoma. The core concept of this type is natural stands dominated by Sapindus saponaria var. drummondii growing on sand dunes and talus slopes on Black Mesa, Oklahoma. Characteristic associates include Andropogon gerardii, Celtis laevigata var. reticulata, Quercus macrocarpa, Rhus aromatica, Schizachyrium scoparium, Smilax bona-nox, and Ulmus americana. Zanthoxylum hirsutum is often a codominant species in this association in the Red River counties of Love, Jefferson, and Cotton counties, Oklahoma.
