One of the more elusive animals in the desert, ringtails are small unique mammals, native to the American west and southwest, Central and South America (Poglayen-Neuwall & Toweill, 1988). Although seldom seen ringtails populations are not considered threatened in Utah or elsewhere in the United States.
