Ecological Region

The Chihuahuan Desert, North America's largest desert ecoregion, is bounded by the Sierra Madre Occidental and the Sierra Madre Oriental; it extends southward into Mexico. Recognized for its biological diversity, the Chihuahuan Desert is a rain shadow desert shaped by the surrounding mountain ranges. Home to unique endemic species, including plants and animals, the region showcases a mosaic of landscapes, from grasslands to shrublands.

The Sonoran Desert, or Desierto de Altar, is a vast, arid region recognized as Mexico's hottest desert. Extending across northwestern Mexico, including Sonora, Baja California, and Baja California Sur, and reaching into southwestern Arizona and southeastern California in the United States, the Sonoran Desert captivates with its expansive and diverse landscape.
