NEWS-PRESS (Ft Myers, Florida) 19 December 04 Large-scale iguana hunt falls short - Gasparilla Island's reptile nuisances escape capture after daylong search (Melanie Payne)
Halftime on the island and there stood the score: Hunters 6, Iguanas 2,000.
Things were not going well for the members of the iguana round-up team. One six-person squad spent 20 minutes stalking Gasparilla Island's nuisances only to bag a little female the size of steak fry.
The search-and-seizure operation was commissioned by the Gasparilla Island Conservation & Improvement Association, which is a nonprofit conservation group on the island. The 7-mile stretch of paradise between Charlotte Harbor and the Gulf of Mexico is inundated with spiny-tailed iguanas — a non-native species that threaten the habitat and breeding of more desirable animals such as sea turtles and gopher tortoises. The iguana population on Gasparilla Island has been estimated between 2,000 and 10,000, far outnumbering the 1,000 year-round human inhabitants.
Cooler temperatures send the iguanas underground. And many residents weren't home to give searchers permission to come onto their property, said round-up leader Jamie Mitchell of Pinellas County.
"Weather is not on our side," Mitchell said Friday evening before the round-up, already sounding pessimistic. Mitchell planned to rescue and find homes for the iguanas after they were tested for salmonella and sociability.
By Saturday afternoon it had warmed up a bit, but Mitchell and her volunteers seemed frazzled and irritable after hours of hunting yielded only a half-dozen captives. Stacks of opaque plastic containers sat empty in the back of an SUV and the volunteers' fishing nets drooped at their sides. Meanwhile, iguanas in the 2-to-3-foot range languished on dunes across the road on state property where the mission wasn't authorized.
The best way to reduce the numbers is to get rid of breeding adults, not hatchlings, said Louis Porras, a Utah-based publisher of biological science books and co-author of book about frogs, lizards, turtles and snakes in South Florida. He endorsed shooting the animals and pulling up and destroying their nests after they've laid eggs. He doesn't advocate poison because it could adversely affect other wildlife. And small round-ups, like the one this weekend, probably won't have much effect on eradication efforts, Porras said.
What may help, however, is something completely out of human control — the cold snap predicted for later in the week.
"When the temperature reaches freezing, it will kill a lot of iguanas," Porras said.
