Description
The Chihuahuan Desert is North America's largest desert, spanning the US-Mexico border region. Creosote bush flats, desert grasslands, and playas support a food web adapted to extreme aridity. Kangaroo rats are keystone species whose seed caching shapes plant community composition, while roadrunners and diamondback rattlesnakes are iconic predators.

- Greater roadrunners prey on rattlesnakes, lizards, and scorpions
- Biological soil crusts fix nitrogen and stabilize desert soils
- Harris's hawks hunt cooperatively in family groups, unique among raptors
