The problem is that Florida's natural ecosystem is effectivly altered. Totally. There's too many invasive plants, let alone insects, mammals, reptiles and birds.
It all started en mass in the 70's, when big-time importers had surplus stock. When the market for an animal went down - so far down, it was not economical to house them - they were thrown out into the glades.
A friend of mine, who worked in the zoos back then, had become good friends with all the big importers/dealers. They told him they took a few dozen snakes, put them in a spot in the glades, and when the market fo rthem went up - they knew where they could collect them. And they did. The things started breeding like crazy. Everything they let go did - monitors, iguanas, anoles, pythons, cobras, mambas - everything. Not everything was released intentionally, of course.
Now, Florida has massive nile monitors, savanna monitors, herds of iguanas, non-native venomous snakes, basilisks, chameleons, poison dart frogs, poisonous giant cane toads, caimen.... pretty much anything you could imagine that's no so expensive that you'd make SURE it didn't escape!
So, idealistically, we'd want to eliminate them invasive chameleons. However, realistically, it's not going to make a difference. Chameleons eat bugs. There's a good chance most of their impact will be against non-native species anyway.
With invasives, the most damage comes at the bottom - plants. Then invasive insects. Chameleons arent' going to do much damage to the overall picture. Plants and insects will - they'll change the entire biotic community.
The large predators, on the othe rhand, can affect individual species directly. Chameleons might be a probelm to say, green anoles - but the brown anoles are even more damaging. Veileds might even help control those little buggers.
Nile monitors are doing a number on the burrowing owls - you can imagine how easily they'd slink down a hole. Large snakes are just dangerous to have out there.
I dont' think eradication programs are good for all these invasives. Unregulated collection is a BAD bad idea. Very bad. Some collection is fine, but there needs to be some laws in place preventign release. That's where the unregulated open season on collection is bad - without checks and balances, it'll encourage people to establish populations of non-native species for collection purposes.
On the other hand, I am not going to get a collection permit!
Anyone find out where they are down there, let me know!
