Several areas in the creek's drainage are home to arid sandyland habitat dominated by Longleaf Pine (Pinus palustris), Blue Jack Oak (Quercus incana) and farkleberry (Vaccinium arboreum). Large deposits of well draining sand left behind by receding seas contribute to the area's xeric nature. Additionally, lack of nutrients in the substrate causes sparse overstory, leading to higher average temperatures and more dryness. Some common understory plants include the prairie prickly pear cactus (Opuntia macrorhiza), Gulf Coast Yucca (Yucca louisianensis), Sandhill sunflower (helianthus debilis subsp. silvestris), as well as rare plants such as Oklahoma Prairie Clover (Dalea villosa subsp. grisea), and the endemic Texas trailing phlox (Phlox nivalis subsp. texensis).[6]
