there have been a few lizards that have been able to survive southern florida and southern texas winters. how long is still a question. iguanas are so popular that they are getting new escapees all the time. note too that none of these lizards eat rodents or amphibians. every four or five winters florida has a more severe winter than usual. pet owners have been successful keeping certain monitors out doors for years until that one winter comes along that wipes out their lizards. some of the southern texas iguanas are thought to be indigenous and they are right at the latitude that the florida lizards inhabit. where i'm from in louisiana there is a breed of escaped parrot that has managed to establish itself and is now surviving southern louisiana winters. this parrot seems to thrive off of fruit from some of our palm trees. i'm sure other species of birds that compete with them are sufferinf from this intrusion, still local residents are enamoured by thes beautiful birds. i am totally convinced that if you and a group of well wishers tried to eradicate this species from the trees to protect the homeland from these horrible creatures that local residents would force you to stop. i think established lizards should have the same rights as birds.
