North American Desert
Physical features of western North America.
The Chihuahuan Desert is home to more than 3,500 plant species, approximately 1,000 of which are endemic, meaning they are found nowhere else on Earth.1
This high level of biodiversity is supported by the region's varied climates, elevations, and soil types. The desert is particularly notable for its cactus diversity, hosting nearly one-fourth of the world’s cacti with more than 400 distinct species. Other characteristic flora includes various yuccas, agaves, sotols, bear grass, ocotillo, and creosote bush.123
