Pythons nose their way into Florida Keys

A couple of long-disused buildings in the Florida Keys that once sheltered servicemen from missile launches have been sheltering something else – pythons.

Four large crawlers – one, a female, was nearly 16 feet long – turned up within the last month at an old missile base at Crocodile Lake National Wildlife Refuge (NWR), the U.S. Fish and Wildlife Service (Service) reported.

Scientists think the snakes migrated from the Everglades, a fertile breeding ground for the unwanted predators. Now, officials say, the snakes may be poised to head south, where several Keys species are defenseless against the large, invasive reptiles.

Compounding their concerns: Officials this past summer also discovered some hatchling pythons near Key Largo – a strong indication that the snakes have found a welcome habitat and are multiplying.

The latest unwanted snakes turned up in a couple of old bunkers where the U.S. military once had a Nike Hercules missile firing range. The site, closed 30 years ago, is now part of the 6,500-acre Crocodile Lake refuge. Searchers using trackers and specially trained dogs sniffed out the snakes, said Jeremy Dixon, who manages Crocodile Lake.

“Snakes like deep, dark places,” he said.

They also like black rats, which likely attracted them to the site, Dixon said. The area also is home to hundreds of feral cats, another potential food source.

The easy availability of food, said Dixon, means the pythons could thrive on the Keys just as easily as they have multiplied in the Everglades. For more than two decades, an array of big snakes have spread and bred in the Everglades. Their presence has had a devastating effect on native birds, deer and other species in the park. Some snakes have even managed to devour alligators.

The Florida Wildlife Fish and Wildlife Commission is working with the University of Florida to detect and remove the snakes in the Keys. They are partnering with the Irulas, members of an Indian tribe that’s renowned for its ability to catch snakes. Read more about those programs.
