In Red Oak Canyon grows a diverse hardwood forest with Texas red oaks, post oaks (Quercus stellata), and cedar elm (Ulmus crassifolia). The deep fertile soils that still remain in the upper portions of this watershed indicate that this catchment has experienced less erosion than the other canyons, most likely a result of the gentle slopes and moderate change in elevation. The deep soils transition into a rocky boulder field in the lower portions of the watershed where some of the larger post oak trees on the ranch can be found. Several species of songbirds and small mammals have been observed utilizing the resources of this forested watershed.
