Florida residents urged to kill iguanas ‘whenever possible’



Non-native species has begun to flourish in state’s warm climate and is causing damage

Non-native iguanas are multiplying so rapidly in south Florida that a state wildlife agency is now encouraging people to kill them.
The Florida Fish and Wildlife Conservation Commission said people should exterminate the lizards on their properties as well as on 22 areas of public land. It did not say how civilians should try to kill them.
“Homeowners do not need a permit to kill iguanas on their own property, and the FWC encourages homeowners to kill green iguanas on their own property whenever possible,” the agency said.
Iguanas are not dangerous or aggressive to humans but they can dig lengthy tunnels, damaging pavements and building foundations. They can sometimes carry salmonella bacteria.
Males can grow to at least 5ft (1.5 metres) long and weigh 9kg (20lb), and females can lay nearly 80 eggs a year.
“Some green iguanas cause damage to infrastructure by digging burrows that erode and collapse sidewalks, foundations, seawalls, berms and canal banks,” the wildlife commission said. “Green iguanas may also leave droppings on docks, moored boats, seawalls, porches, decks, pool platforms and inside swimming pools.”
Iguanas are native to Central America, tropical parts of South America and some Caribbean islands. They were brought to Florida as pets or inadvertently on ships and have begun to flourish in the state, where the warm climate is perfect for them.
Some have been reported in northern parts of Florida, but their spread is more limited there as they do poorly in colder weather.
Another invasive species, the Burmese python, is wreaking havoc in the Everglades as they eat almost anything and have no natural predators in the US, except for the occasional alligator.

Florida’s solution to its invasive iguana problem: Smash their skulls in – via Herp Digest



By Alex Horton 3/18/19, Washington Post

They canvass southern Florida at night, in teams of two, armed with flashlights and bolt guns to stun and smash the brains of intruders.

Invasive iguanas tearing across properties and destroying local infrastructure have been put on notice by a team of wildlife biologists from the University of Florida, deputized by the state to kill them using methods as humane as possible in an ongoing experiment with collection and removal techniques.

The preferred killing method is blunt force trauma, Frank Mazzotti, a wildlife ecology professor at the university, told The Washington Post on Monday. “Death is instantaneous, as is destruction of the brain. No pain is felt by the animal,” he said.

That means, when available, the scientists use captive bolt guns that discharge a fast-moving metal rod, commonly utilized in the cattle industry and the weapon wielded by villain Anton Chigurh in the 2007 film “No Country for Old Men.”

It also sometimes involves using deadly blows with other methods, like hitting them with hammers or swinging the iguanas hard into concrete. The scientists have gone out for six nights so far, often pulling iguanas right off trees as they sleep. Traps are set up in places like parks away from residential areas.

Mazzotti said the killing methods are in line with regulations established by various bodies, including the American Veterinary Medical Association.

The count so far: about 300 iguanas, some killed on the spot after they were trapped, with others later taken to be euthanized. The teams operate along a canal on the northeastern edge of the sprawling Everglades preserve in Davie, north of Miami.

Iguanas tend to colonize the man-made canals, the Florida Fish and Wildlife Conservation Commission says, an accidental proliferation aid for the lizards traversing the watery veins of Floridian suburbia. Density along water management areas makes iguanas more of a nuisance, requiring mass removals. Two nights alone netted about 200 iguanas.

The university’s work is underwritten by the commission. The commission provided $63,000 for the research project running through May that also includes weighing and measuring carcasses before they are properly disposed of at an authorized landfill, the Sun Sentinel reported.

The iguanas, clearly, are not welcome. They do not even belong.

The natural habitat of the common green iguana stretches from Mexico through Central America and throughout the entire Amazon region in South America, including islands in the Caribbean and off the Brazilian coast, a map on the commission website shows.

According to the Sun Sentinel, iguanas arrived in Florida as pets, first appearing in Miami-Dade County in 1966, then in the Keys in 1995 before making a home of Broward County in 2001 and in Palm Beach in 2003. The total population is unknown, Mazzotti said, but the southern portion of the state has reeled from proliferating numbers. Iguanas can lay dozens of eggs at once.

Iguanas are attracted to dense trees and fruit — kind of what Florida is known for. They destroy landscape vegetation, and their burrowing speeds erosion, leading to the collapse of sidewalks, foundations and canal banks, the commission says.

If that is not enough, they can also transmit salmonella to humans that come into contact with water tainted by their feces — in swimming pools, for instance.

The commission carefully spells out how iguanas can be captured and killed. They recommend using nets, cage traps and noose poles for the famously agile, spiky-tailed creatures. But then it gets complicated.

You can kill one with a single blow from say, a shovel, but you must strike true. More than one blow could be animal cruelty punishable by prison time and up to $5,000, Ron Magill, an animal ambassador for Zoo Miami, told the Sun Sentinel.

“Unless you have an animal that you can have in your hand, [killing humanely] is very hard to do,” Magill said.
Trapping and relocating iguanas to a more isolated place is also forbidden, Magill explained, because the practice could transmit viruses and bacteria to ill-equipped wildlife.

Also: Do not poison or freeze them, experts warn.


Florida exotic pet veterinarian Susan Kelleher told the Sun Sentinel she considers the head-bashing inhumane and suggested sedating and euthanizing the iguanas. She did not return a request for comment. Mazzotti noted they do indeed euthanize iguanas.

Most residents can use pellet guns to kill iguanas, provided they are legal in their  area. One resident, Gary Fishman, told the Sun Sentinel he has racked up more than 100 iguana kills with his pellet gun.

“The iguana does not belong here,” he said. “They need to be annihilated. They can’t be relocated. So they must be destroyed.”

Mazzotti cautioned against that method.

The scientists have recovered iguanas with pellets lodged in their skin from botched kills, meaning the lizards, however loathed, probably suffered.

“That’s not humane,” he said.

How do so many iguanas get in Florida toilet bowls? – via Herp Digest


by Craig Pittman, 12/5/17, Tampa Bay Times

Iguanas are commonly found in Mexico, Central America, South America, and the Caribbean. In 2017, you could add "Florida toilets" to that list.

So far this year, news stories reported that iguanas have turned up in Florida commodes at least five times — although there’s reason to believe it’s happened more often than that.

What are they doing in the toilet? Besides the backstroke, that is? Trying to get out.

Although other animals have been known to intrude into toilets — rats, for instance — iguanas are perfectly adapted for plumbing infiltration. The voracious little Godzillas, which can grow to be 6 feet long from snout to tail, frequently climb trees, and also tend to be good swimmers, able to hold their breath for an extended time period.

From the trees "they come down from the vent pipe in the roof," explained veteran Boca Grande iguana trapper George Cera, who has written a cookbook called, "Save Florida, Eat an Iguana." "Even if your vent pipe is closed, that doesn’t mean your neighbors’ is.”

Once an iguana gets into someone’s plumbing, it can quickly wind up swimming in the sewer system, he explained. Then it’s looking for a way to escape.

"It’s the luck of the draw where they come out," he said. "The next place place to pop out is your 3-inch toilet pipe.”

In other words, while New York’s sewers may not be filled with alligators, as the legend has it, Florida’s sewers do apparently team with toothy green iguanas that frequently pop up in the pooper.

Among the many perils that Floridians regularly confront — the state gets more hurricanes, lightning strikes, sinkholes and shark bites than anywhere else in the U.S. — finding an iguana in the toilet is unique. Not only does it happen more in Florida, but a Lexis-Nexis search of news stories from around the nation reveals that it happens only in Florida.

This year is not the first time an iguana has turned up in a Florida toilet. For instance, in 2015, a woman in Fort Lauderdale called Roto-Rooter to clear a clogged commode, only to hear the plumber scream upon yanking out an iguana. It died — the iguana, that is, not the plumber.

But this is the year when reports of iguanas in toilets repeatedly hit the news.

The most recent toilet iguana to make news happened in Hialeah on Nov. 30. A man named Giovanni Profera told Telemundo last week, "I sat down, I felt pressure, I jumped and saw a lizard."
The iguana scrambled out of the bowl and fled, no one knows where. Meanwhile, Profera said he’s now terrified of using the bathroom.

Also last month, a women in Palmetto, in Manatee County, was going to clean her toilet but freaked out when she discovered an iguana swimming in the bowl. She has been afraid of lizards since she was five.

"I didn’t know what it was at first, so I instantly screamed and my 9-year-old daughter come running in and she said, ‘Mommy what is it?’ and I said, ‘I don’t know,’ " Dani Craven told WFLA-TV. "All I could see were scaly, like a scaly tail. I couldn’t tell if it was an alligator or a lizard. I didn’t know.”

Her husband wasn’t home and she wasn’t about to tackle it alone. She put out a cry for help on Facebook and a neighbor came over armed with rubber gloves, a net and a cooler. The neighbor caught the creature, even though it kept hissing at her. She took it to a wildlife rehabilitation facility.

In August, a man in the South Florida community of Medley was trying to unclog a toilet when he looked down the drain pipe and saw an iguana peering up at him. The man’s uncle calmly caught it with a loop of rope, then walked it outside as if it were on a leash and turned it loose, which means it can go invade someone else’s toilet.

In July, Univision reporter David Adams, a former Times Miami bureau chief who lives in Key Biscayne, donned ski gloves, a gas mask and a bulletproof vest to remove an iguana from his toilet. He captured it by wrapping it in a beach towel. He, too, chose to release the lizard back into the wild.

"He hissed at me and had a couple of jaw snaps, but then scampered away to rejoin the reptilian hordes in our neighborhood," Adams wrote in a Facebook post about the encounter.

In May something similar happened in the Miami suburb of Kendall. A woman lifted the lid of her commode, spotted the iguana, closed the lid and dialed 911. Miami-Dade Fire Rescue’s "Venom Unit" — which routinely handles calls involving pythons and other snakes — captured the critter, and afterward said it was a first for them. They took it to a wildlife rescue center.

Florida is infested with more exotic and invasive species than any other state, with the roster ranging from feral hogs originally imported by Spanish conquistadors to giant African land snails smuggled in a few years ago by a religious cult.

Pythons are the best known, although they are largely confined to the Everglades, but iguanas are among those that have spread the most widely across the state. They devour sea turtle eggs and shorebird nestlings, and leave behind feces that may carry salmonella bacteria, which can cause food poisoning, typhoid fever and other ailments.

The earliest official report of iguanas roaming the Florida wild dates back to Miami-Dade County in 1965, according to Sarah Lessard, a spokeswoman for the state Fish and Wildlife Conservation Commission. Now they are found all along the Atlantic coast from Martin County down to the Keys and in isolated instances have been found on the state’s west coast as well.

The next official sighting, from 1979, came from the island community of Boca Grande, near Fort Myers. Local legend says a Boca Grande resident brought a pair back from Mexico as pets, then either turned them loose or lost them, and they became the Adam and Eve of a huge Florida iguana colony.

By 2007 the island was overrun by thousands of the lively lizards. Finally Lee County assessed a tax to pay for a trapper, making it the only place in America with an iguana tax. In just his first two years on the job, Cera, the trapper, caught 16,000 iguanas. As of last year he was still averaging about 2,000 captures a year.

A similar drop has occurred in reports of iguanas in Boca Grande’s toilets, Cera said — but it has never entirely stopped.
"Back when the population on the island was larger, it would happen two or three times a month," he said. "Now it’s maybe one or two times a year." None of those incidents made the news, suggesting that there are some iguanas that, like a politician facing indictment, manage to find a way to slip past reporters.

Cera, whose cookbook includes recipes for such delicacies as iguana tacos, said the frequency of iguana toilet sightings has made him wonder what sort of animals routinely pop up at Florida’s sewer plants.

Bill Logan, the spokesman for St. Petersburg’s public works department, said city officials are unaware of any iguanas appearing in the city’s sewer system. But two years ago, he said, workers shutting down the old Albert Whitted sewer plant caught an 18-inch-long Australian catfish swimming in the aerators. They figured someone had flushed the fish when it was smaller and it just kept growing.

Nobody, he said, was brave enough to eat it.

Iguanas partner with the plants of the Galápagos Islands




Date: December 7, 2016
Source: Plataforma SINC

The isolation of ocean islands like the Galápagos prevents the arrival of large mammals, which disperse the seeds of many plants by ingesting them. In the absence of mammals, this function is filled by birds, tortoises, lizards and iguanas. To date, no investigation had been carried out into the role iguanas play with at least ten species of plants.

The survival of many native and introduced plants depends in part on the role of animals in pollination and seed dispersal. The ingestion and subsequent expulsion of seeds in animal faeces means a proportion of them return to the soil at a more distant location.

In addition to birds, the Galápagos giant tortoise is the animal that disperses most of seeds over great distances on the islands, followed by the endemic land iguanas, of which there are three species which feed on fruit and vegetation near ground level, as they do not climb. However apart from anecdotal records, their potential for seed dispersal had not to date been confirmed.

A study published in the journal 'Integrative Zoology' demonstrates for the first time how by dispersing seeds, the Galápagos land iguana (Conolophus subcristatus) contributes to the survival of indigenous and introduced plants plant species on Fernandina Island, which covers 642 km2 of land.

Feeding by Tourists Compromises Health of Already-Endangered Iguanas, Study Finds

Dec. 5, 2013 — Feeding wildlife is an increasingly common tourist activity, but a new study published online today by the journal Conservation Physiologyshows that already-imperilled iguanas are suffering further physiological problems as a result of being fed by tourists.

Charles Knapp, PhD, of the John G. Shedd Aquarium in Chicago and colleagues compared the differences in physiological values and endoparasitic infection rates between northern Bahamian rock iguanas inhabiting tourist-visited islands and those living on non-tourist-visited islands. They took blood and faecal samples from both male and female iguanas over two research trips in 2010 and 2012. The Bahamian rock iguana is among the world's most endangered lizards due to habitat loss, introduced mammals, illegal hunting, threats related to increased tourism, and smuggling for the illicit pet trade. They are listed on the IUCN Red List of Threatened Species™.

Puerto Rico plans massacre of invasive iguanas, export of harvested meat (via Herp Digest)

The invasive species outnumber humans on the US Caribbean territory but the local government is drawing up plans for a volunteer force to eradicate the lizards.

Global Post.com, News Desk, February 3, 2012 , Puerto Rico has announced plans for a massive cull of an invasive species of iguana and for the sale of harvested meat, according to The Associated Press.

The US territory hopes to eradicate the species with a population of four million, which the AP says outnumbers humans on the island and has long been considered an invasive nuisance.

According to the AP, Daniel Galan Kercad, secretary of natural resources, said his agency had been granted permission to draft plans for volunteers to bring the iguanas to a slaughter house which would distribute the meat.

The AP said he claimed the meat was popular in areas with large Asian and Latino populations.
Puerto Rico may not be the only place trying to eradicate pesky herbivorous lizards. Daniel Klein of The Huffington Post wrote yesterday that the city of Boca Grande in Florida "has hired a man to drive around in a golf cart, shooting iguanas." Klein said the Florida Iguana was just one of many invasive species in the US that authorities were encouraging people to hunt and which were increasingly considered for sustainable food dishes.

Despite their plentiful population, iguanas may still be valuable. Reuters reported in June that US Customs and Border Protection agents on the Mexican border had seized 159 pounds of smuggled iguana meat with an estimated value of $4,500.

"There could be a number of reasons but one of the main ones that comes to mind is that there are parts of the world where people do eat iguana meat as a delicacy," Jackie Wasiluk, a spokeswoman, said.
