Which five US states define the primary concentration area for Crotalus atrox?
Answer
Southern California, Arizona, New Mexico, Texas, and Oklahoma
The core population concentration for the Western Diamondback Rattlesnake within the United States is specifically situated across states that share borders with Mexico, where the species thrives in drier climes. These primary states are listed as Southern California, Arizona, New Mexico, Texas, and a portion of Oklahoma. This grouping reflects the species' strong preference for lower, drier elevations characteristic of the southwestern US landscape, where the Sonoran, Chihuahuan, and Mojave Deserts dominate the environment.
