I guess those should be included. My sister and her husband bought a big piece of property down in Eloy area. Big piece of land in the desert but millions of rattle snakes. Turned out up a desert road was a snake den. They had to clear it out.
I also forgot I did see a Gila monster when sitting on a very large boulder in a desert piece of land that now is built on but back then it was empty, just off Cave Creek Road and Cactus Road with a mountain on it.
We have a place just across River Rd. near Campbell in Tucson (actually in County) at beginning of foothills. Loaded with king snakes. Supposedly they keep the rattlers down.
I saw a Gila monster—and its relative the Mexican beaded lizard—in the Arizona Sonora Desert Museum. Nowhere else!
