They're doing better than the Arizona (where I now live) desert tortoise. I used to see them back in the 70's and 80's but never any more. They are now considered a threatened species. I used to see a lot more wildlife when I went hiking in the desert back then than I do now - gila monsters, tarantulas, snakes...but contrary to popular belief the biggest scariest rattlers I've seen were not in Arizona but in New York State, and NJ had plenty too...though one did bite me in California near Death Valley.
