Falling Iguanas: Florida’s Cold Snap Causes Nonnative Lizards to Drop from Trees

Iguanas May Drop from Trees as Florida Faces Unusual Cold Snap

TAMPA, Fla. – As temperatures across Florida plunge, residents are being warned to watch their heads—falling iguanas may soon be a common sight. The Florida Fish and Wildlife Conservation Commission (FWC) has issued a reminder about the potential for nonnative green iguanas to tumble from trees as the state experiences a significant drop in temperature.

With forecasts predicting near-freezing conditions, the FWC explained that iguanas can enter a state known as “cold-stunning.” This occurs when temperatures dip below 50 degrees Fahrenheit, causing these reptiles to lose muscle control and become immobilized. As the mercury falls, iguanas, which rely on sunlight to regulate their body temperature, may lose their grip on branches and fall to the ground.

“While it may sound alarming, most iguanas are not dead when they fall,” said an FWC spokesperson. “They typically recover after a few hours of warmth.”

Residents are advised to take precautions if they encounter a cold-stunned iguana. The FWC recommends against bringing the reptiles indoors, as they can recover quickly and may become defensive if handled. Additionally, pet owners should keep their animals away from iguanas, whether they are active or in a state of torpor.

It’s important to note that iguanas are considered a prohibited species in Florida, and capturing or relocating them requires a permit. The FWC encourages humane treatment and advises against releasing them back into the wild.

This unusual cold snap is not the first time Florida has seen iguanas fall from trees. The phenomenon has been reported during previous cold weather events, with iguanas often found lying belly-up in parks and backyards.

Iguanas have been part of Florida’s landscape since the 1960s, thriving in the state’s warm climate. However, their presence has raised concerns due to the damage they can inflict on infrastructure, including seawalls and sidewalks. As a result, they were added to Florida’s prohibited species list in April 2021.

As the New Year approaches, residents are reminded to stay vigilant and keep an eye out for these unexpected “drops” from above. Whether it’s the iconic New Year’s ball or a cold-stunned iguana, it seems that this week, Florida is in for a surprise.
