The park offers a rich variety of avian habitats: mesquite grasslands; live oak, post oak, and cedar woodlands; open water and the margins of the Pedernales River including a narrow pecan gallery woodland. Live oak, post oak, mesquite, juniper, native pecan, sugar hackberry, yaupon, and sumac are abundant.
