| Southern Plains Woodrats are found in places where grasses, creosotebush, mesquite, and cactus grow. Local populations can reach high levels and then crash. Crashes can be associated with changes in habitat—for example, an unusually rainy year may kill cactus the Woodrats rely on for food. Like many rodents, these woodrats are active between dusk and midnight. When disturbed, individuals thump or drum their hindfeet, possibly to communicate territorial ownership. They live in association with many other mammals, including armadillos, cotton rats, kangaroo rats, grasshopper mice, jackrabbits, and cottontails.
