Florida has an iguana problem and the coldest winter in years, so it has euthanized more than 5,000 frozen iguanas

In the Iberian Peninsula we are having one of the winters with more rainfall in recent yearsbut in the United States they are not exactly having a mild winter either. New York has arrived register colder than in Antarctica and not even the state of the sun has been saved: Florida has broken a cold record of more than 100 years. Thus, Miami or West Palm Beach have fallen below 0°C, something that It hasn’t happened since 1909. This extreme cold literally freezes the iguanas. And that has made it very easy for the Florida authorities to “euthanasia” 5,195 specimens

Florida has a serious problem with iguanas. As happens in Spain with the catfishes either in Italy with blue crabs (among other parts of the Mediterranean), the United States has invasive species like the Asian carp, which bothers it so much that They have come to electrify the riversor the iguana, which mainly affects southern Florida.

In addition to biodiversity problems derived from introducing an outside species into an ecosystem, altering the trophic chain or that its feces are natural carriers of salmonellais that they constitute a real danger to infrastructure: they build burrows up to 24 meters deep, damaging sea walls (a 1.8 million dollar problem in West Palm Beach), building foundations and even blackouts. Not to mention the risk that an iguana falls from a tree to the head or the hood of your car. Friendly reminder that iguanas can come to measure two meters long and weigh more than 13 kg.

It’s raining iguanas. Literally. You probably read the above with surprise because, well, from time to time a little bird falls, but a tremendous iguana is less common. The iguanas They arrived in Florida in the 1960s. and since then they have moved quietly through courtyards and canals. The Sunshine State has a subtropical climate and iguanas are cold-blooded reptiles, but for much of the year, they adapt.

But winter comes, especially a winter as cold as this one, and the iguanas are stunned by the cold. They are ectothermic speciesthat is, their body temperature is strongly determined by the environment (they do not generate their heat, as mammals do), so they freeze. This cold stunning affects internal processes such as metabolism, breathing or heart rate. And this is what leads them to fall from trees because they are in standby and lose their grip.

A chance to get rid of them. So the Florida Fish and Wildlife Conservation Commission (FWC) has taken the opportunity to implement executive order 26-03which temporarily allows anyone to pick up one of those cold-stunned green iguanas without needing a permit to bring it to authorities. In the first two days of February, Residents brought 5,195 copies. Subsequently, they were sacrificed following American Veterinary Association guidelines (AMVA). Or from a technical point of view, they “euthanized” them.

Animal welfare vs pest control. According to the FWCnon-native reptile species such as green iguanas or Burmese pythons are only protected by animal cruelty laws. The procedure is known as “euthanasia” insofar as the method of death must be irreversible, rapid and painless. Precisely at that moment in which they are lethargic is the moment considered the most humanitarian to act.
