Northern Desert Iguana

Dipsosaurus dorsalis

Summary ⁷

The desert iguana (Dipsosaurus dorsalis) is one of the most common lizards of the Sonoran and Mojave deserts of the southwestern United States and northwestern Mexico. They also occur on several Gulf of California islands.

Range description ⁸

This species ranges widely in southwestern United States and northwestern Mexico. Its range encompasses southern Nevada, extreme southwestern Utah along the Virgin River in the vicinity of Beaver Dam Wash (at least formerly), and southern California east of the Sierra Nevada and Coast ranges southward through northeastern Baja California and all of southern Baja California (but not most of the Vizcaino Desert) and through western and central Arizona and western Sonora to northern Sinaloa. This lizard occurs on many islands in the Gulf of California and on Magdalena and Santa Margarita islands along the Pacific coast of Baja California (Hulse 1992, Grismer 2002, Stebbins 2003). The range in the United States coincides closely with that of creosote bush (Stebbins 2003). Elevational range extends from below sea level in desert sinks to about 1,520 m (5,000 feet) (Stebbins 2003).
