a few websites to start with.......
New Mexico Administrative Code - Title 19, Chapter 35, Part 7 - Amended
New Mexico Administrative Code - Title 19, Chapter 35, Part 7 - ORIGINAL
New Mexico Administrative Code - Title 19, Chapter 35, Part 10
In the first 2 links pay particular attention to non-game regs. Just as in Utah, New Mexico requires you to apply for an importation permit; otherwise it's illegal to import pretty much anything into the state. How the state defines import I don't know, but I assume the intent of the law is to bring anything into the state itself. Utah is currently or has currently made a precedence on this law via Ryan Hoyer. The 3rd link covers NM's regs on protection of amphibians and reptiles. We do have possession/bag limits, some interpret it to apply annually, inferring you can possess more than what the bag limit says. I like to view it more along the lines of how AZ is: bag limit = possession limit, any time, any place, within the state. You'll notice the bag limit info is also not available within that 3rd link. I have a WORD document of the original 2001 regs that includes the bag limits, but I'm unsure how accurate that is these days. I may know more later this month as I'm set to renew a NMDGF permit and fill out our year-end report.
Off the top of my head on what's off limits (protected - either threatened or endangered, state or federal), unless you apply for a permit from NMDGF...
-green rat snake
-gray-banded kingsnake
-blotched water snake
-NM ridge-nose rattler
-mottled rock rattler
-sonoran desert toad
-great plains narrowmouth toad
-gila monster
-western river cooter
-and a few other species my mind isn't recalling at this hour.
As for city code:
City of Las Cruces - Municipal Code - Chapter 7: Animals
After having peed into your cheerios now, on a more positive note...
Come check out the Las Cruces Museum of Natural History when you get into town. I'm the Naturalist there, overseeing our nature center department; which is home to ~31 species of herps native to the Chihuahuan Desert and/or NM, plus a few other critters.
It's not much now, but it's something, and we're currently in the beginning process of moving from a 4200 square foot facility to an ~8500 square foot facility.
