‘Shocking’ iguana numbers pose environment crisis

| 20/06/2016 | 103 Comments

Cayman News Service(CNS): Local experts now believe that there are around half a million invasive green iguanas on Grand Cayman. Early estimates indicate the population is doubling annually and there could be well over a million by this time next year. Research by the Department of Environment has revealed that the number of iguanas is far higher than originally estimated and they have gone well beyond a nuisance, reaching an environmental crisis and posing a real threat to the islands’ natural resources and for some species. such as the red birch, extinction. 

Speaking at a press briefing Friday, Fred Burton, who is better known for his work saving the famous blue iguanas from extinction but is working with DoE to find ways to reverse the alarming growth of the greens, explained that the invasive iguanas are decimating foliage and competing with other native animals and birds for food. They are also stripping trees and bushes in the wild and in gardens and farms, Burton said, warning that the situation is extremely serious.

“It’s hard to grasp the magnitude of the problem,” he said. “We had no idea that the rate of increase was so great.”

Burton said that, given the massive problem for the environment because of the impact on vegetation, there had to be a determined cull. As well as causing havoc in gardens, out in the wild the green iguanas could cause the extinction of some of Cayman’s unique species.

With the speed at which the iguanas are stripping plants, bushes and trees of flowers and berries, Burton said, “We don’t know what might happen.”

The green iguanas are eating the berries on many local trees, including the red birch, which many local birds also eat. They are consuming at such a rate that not only are they competing for food, but also putting the tree, which is already threatened, at risk of extinction if the number of iguanas is not dramatically reduced and contained.

DoE Director Gina Ebanks-Petrie explained that over the past year, after the National Conservation Council was given $200,000 from the Environmental Protection Fund for the purpose, researchers and scientists have been analyzing the population and working on options to cut the numbers, as it is clear that a “major solution” is required and quickly.

The DoE began the cull pilot study with a group of professional cullers, who were tasked with reducing the population in a given area by 90%. The three hunters brought in around 4,000 iguanas. With baseline data in the area from the surveys, DoE researchers are now calculating how much of an impact that has had on the population numbers in the survey area.

The second pilot study begins Monday and will last for one week using only local registered cullers who had expressed an interest at a public meeting last year in taking part in any national culls. The department has signed up 18 individuals who will be using different methods, from dogs to air rifles, and will be given $5 per iguana culled on the western side of the island.

The registered cullers have been asked to dispatch the iguanas quickly and humanely, cutting down on unnecessary pain and suffering. Although they can enlist others to help them, only the registered cullers will be paid at the end of the week for the iguanas they bring in and have committed to taking responsibility for any teams they assemble and seek permission from landowners wherever they hunt.

At the end of the week the DoE will than compare the pilot cull results and make a decision on the way forward for a sustained long-term project to cut the numbers. The goal of the pilot studies is to determine whether a small number of highly trained high-tech cullers or a larger group of locally registered hunters receiving a bounty will be the most successful.

    As a tourist there nothing worse than having the iguanas around the pool area and the poop all over the place. When I first started coming to Cayman you NEVER saw a green iguana!

    Well, if you live at Caribbean Paradise, you will learn they just cut down the trees that the iguanas lived in so they would stop pooping on the pool furniture and an owners car. They think that solved the problem. So let’s just cut down the trees and get umbrellas.

    Let this be a lesson for the lovely Aedes mosquito (also an invasive species) that us clever people would like to bring in more of like 22 million more. Say they don’t die then we have an island overrun with green iguanas and mosquitoes – lovely. Only we can’t shoot the mosquitoes and can’t kill with insecticides since they live in close proximity to humans. Who is the genius that allows these species to be brought in? One way to ruin an island.

    What a waste of tax payers money! Do they really believe air rifles and a couple of nooses is going to eradicate these evasive creatures? I recalled in my younger days when there was a bounty on agoutis. I got my fair share and made a couple of pounds. But today the agoutis are still here despite the bounty on their heads and are now hardest hit due to destruction of their habitats and over development. I know of a couple of hunters that still hunt the agoutis to this very day some time 6 and 7 in one day yet there’s no reduction in their population and considering they only have 4 to 8 young ones a year compared to the iguana that has 50 – 75 eggs at one given time 4 to 5 times a year.

    Someone is getting rich I say!

    I have to wonder what environmental dept says about this and their own failings here. The law should have been changed many years ago to allow for the culling of the green iguanas and Environmental Dept should have led the charge. Instead the green iguanas were protected by the law which was intended to protect the blue iguanas. Everyone could see that they were a destructive invasive specie and nothing was done to even begin to address the problem until it was too late. There is talk about the iguanas carrying diseases too. The actual harm they have been allowed to cause is yet to be fully determined or known.

      Calm down. They send pest controllers to lay noxious, indiscriminate poisons in your yards and they fly over and drive around spraying insecticides over your yards, cats, dogs and children.
      We’re not talking about snipers sneaking through the bush, these animals are often in the open and very approachable, so shooting from a close range shouldn’t be a problem.
      That is why they are allowing licensed shooters and not saying to all ‘go shoot an iguana’, the risk of an accidental shooting is almost zero and if you had any sense, when the pest controller comes around, take your kids and animals inside.

        we don’t use Pest control hardly ever, we are very sensitive and wise of such harsh chemicals, i cannot calm down because nothing is ever done right in this island or when it’s too LATE! If another neighbour allows them in their yard those pellets can hit into my yard, so it is no protection to my yard even though i would NEVER allow them in my yard!

        They say they will allow the registered shooters to round up their own little gang to work with them. Now BOYS, you gonna tell me with all your testosterone that they and you will not let them use the gun sometimes too. C’mon BOYS, you know you have testosterone OVERLOAD and all want the excitement of firing the gun!

          An air rifle is likley to be lethal (to Iguana’s) over a short range, 40 yards is probably the outside limit of an air pellet, so I would doubt you are in any danger from a stray pellet. I was shot when I was a kid, barely broke then skin at about 25 yards. 25 yards is pretty close, unless someone is standing on your property line aiming directly at you, which you would probably notice.

    The public in Cayman have been talking about the decimation of the landscape and the fight for survival of other birds etc. for ages. No one would listen!! When the lion fish were threatening the environment in the sea something was done about it quickly. Not so when the islands landscape was being destroyed. Not to mention poop in pools and all over the gardens and tunnels everywhere as well. Anyway, it is wonderful that someone is finally listening and understanding the severity of this terrible problem. It would have been so much easier if the ears that could do something about it well over a year or more ago were not deaf to all concerns previously expressed.

    The dark side of the imported pet trade. Readers may remember many years ago some twits proposing to import ferrets.

    Back in the sixties it was the agouti. But even rabbits don’t breed like iguanas, although farmers were paid a head tax to kill agoutis.

    A massive culling program is required. The current solution of relying on drivers and pets is not enough and the island is totally disgusting with rotting carcasses everywhere.

        Bart and Marge take the lizards to the Springfield Birdwatching Society. Principal Skinner, a member of the society, explains that they are Bolivian tree lizards, a type of lizard that steals a bird’s eggs and leaves their own eggs to be watched after by the mother bird, which is then eaten by the offspring once they hatch. Skinner says the lizards must be killed by law, because they have killed many bird species. Bart escapes and runs away with the lizards, but before he can get away, Skinner catches up to him and they both struggle on top of the building. Suddenly, the lizards glide to the ground, where they start to eradicate pigeons in Springfield.
        Since the town considered the pigeons to be a nuisance, they are delighted that the lizards have eaten all the pigeons. So, Bart is thanked and honored by Mayor Quimby with a loganberry scented candle. Lisa worries the town will now become infested by lizards rather than the pigeons, but Skinner assures her they will send in “wave after wave of” Chinese needle snakes, then snake-eating gorillas, and then “when wintertime rolls around, the gorillas simply freeze to death.from the simpsons:

        No, that’s why it’s illegal to hunt with dogs in the UK. It’s only the moronic and deeply disturbed who find pleasure in allowing an animal to be ripped apart by dogs.
        But hey it’s Cayman, the home of the moronic and deeply disturbed!

        CNS: Fox hunting in the UK was banned just 12 years ago with the passing of the Hunting Act (which was supported by just six Conservative MPs at the time). Prime Minister David Cameron, like many now sitting in Westminster, a keen fox hunter back in the day, tried to repeal that ban six months ago in December 2015. You know that, right?

        • Jotnar says:

          What’s your point CNS? It is still illegal in the UK and has been for 12 years. Are you saying that somehow doesn’t count?It’s about the same period of time that homosexual relations were legalised in Cayman. Shall I denigrate that change in law as well since it hasn’t been on the statute book for long enough to really count? How long does it have to be before a country get credit for reformist legislation according to your perspective?

          CNS: Clearly I am not denigrating the change in British law to outlaw fox hunting, since it is something that I very much agree with and well remember the struggle to get there — the anger and sometimes violence directed at the hunt saboteurs (people who spent their Saturday’s during hunt season trailing aniseed around the countryside). The joy at having beagles rip foxes apart for sport was a very hard custom to break. And while Britain took a huge step forward by banning a disgustingly barbaric practice, no, I don’t think that 12 years is long enough to be smug about it, especially when there was a serious move to bring it back just six months ago.

        The idea of offering a bounty for what has become a national emergency is frankly stupid and a waste of public money. Spend the money on a long term fix, not a short term gain.

        Why can’t the DoE employ more Conservation Officers to combat this problem? I’ll tell you why, because DoE management are dictated to by our petty politicians whose own agendas come first. Instead of employing enough professional officers to protect all of our environmental treasures, the member for EE and his buddy on NS just want to bully government departments and private companies into taking on the inexperienced and uneducated just to fill their nationalistic agenda. My god, they don’t even have enough staff to protect the conch and lobsters from local poachers, but I bet good money that these MLA’s will have a plentiful supply of local marine life at their pre election gatherings.
        With clowns like these two in power, how on earth will this country ever progress, let alone get to grips with an impending environmental catastrophe on many fronts?
        Stop settling for ordinary, employ the best people to do the job, from wherever they may come from and don’t let the bullies win.

      I agree that it is an opportunity lost. I have been told that iguana meat sells for more than shrimp in Honduras so that could be part of this venture too.

      One of the obvious problem is if it is successful it would not be sustainable unless iguanas were then bred in captivity once all of the wild ones are captured. Another issue would be people purposely breeding them to collect the bounty. This could potentially make the problem worse if people are breeding them faster than the cullers can capture them.
