Florida removes over 5,000 cold-stunned iguanas after rare freeze

Residents and officials work together to remove cold-stunned reptiles

Florida’s unusual February freeze left thousands of green iguanas falling from trees, immobilized by the cold. Residents and wildlife officials raced to respond, collecting the stunned reptiles before they could recover.

The effort exposed both the challenges of managing invasive species and the unexpected ways extreme weather can impact local ecosystems.

From icy lawns to emergency collection sites, the state saw a rare convergence of extreme weather and rapid human response.

How cold weather affects iguanas

Green iguanas are ectothermic reptiles, meaning they rely on external heat sources to regulate their body functions.

When temperatures drop into the mid-30s to low 40s°F, their metabolism slows and muscles stiffen, rendering many iguanas immobile in a state of torpor.

During torpor, iguanas can lose their grip on branches and fall from trees or vegetation. This natural response helps them survive short cold spells but leaves them vulnerable until temperatures rise.

FWC issues temporary collection order

The Florida Fish and Wildlife Conservation Commission (FWC) issued a special executive order allowing people to collect live, cold-stunned green iguanas without a permit and bring them directly to designated FWC offices.

The order was in effect only on February 1–2, 2026, and covered iguanas removed by property owners or by others with landowner permission in affected regions.

Collected iguanas had to be transported to FWC drop-off sites for processing. The temporary measure aimed to reduce the invasive population while maintaining public safety and compliance with state law.

Number of iguanas collected during the freeze

Over the two-day collection period, residents and officials turned in 5,195 iguanas to FWC drop-off locations across the state. The highest numbers came from the Sunrise location with 3,882 iguanas, followed by Tequesta and Marathon, showing the regional concentration of the species.

This effort highlights both the scale of the invasive population and the public’s willingness to participate in emergency wildlife control. The figures also provide valuable data for future population management strategies.

Locations designated for iguana drop-off

FWC set up five official drop-off sites across South and Southwest Florida to streamline the collection process. These included Marathon, Sunrise, Tequesta, Fort Myers, and Lakeland, giving residents several accessible places to participate safely.

The sites were staffed with FWC personnel trained to handle and process iguanas properly. This setup helped minimize risks for both people and animals while keeping the removal effort organized.

Handling iguanas after collection

At the drop-off sites, FWC staff determined whether iguanas could be transferred to licensed dealers or required euthanasia. Most iguanas were humanely euthanized according to state guidelines because relocation capacity was limited.

Humane euthanasia is performed to minimize suffering and prevent escape. This ensures the invasive species does not rebound into the wild immediately after the cold snap.

Why iguanas are considered invasive

Green iguanas became established in Florida in the 1960s, primarily through the exotic pet trade and cargo transport. They reproduce quickly and thrive in urban and suburban environments, causing significant damage to native plants and infrastructure.

Burrowing behavior can destabilize seawalls, and their feeding habits compete with native species. These characteristics classify iguanas as prohibited invasive species under Florida law.

Public response to iguana sightings

Residents shared photos and videos of cold-stunned iguanas on lawns, sidewalks, and streets, spreading awareness across social media platforms. The striking images captured attention and prompted widespread discussion about the unusual weather event.

Wildlife experts advised caution, reminding the public that even immobile iguanas can injure people with claws or tails once they regain movement. This guidance helped reduce the risk of injury during collection.

Safety guidance for handling iguanas

Experts cautioned residents against warming cold-stunned iguanas in homes or cars, as this can cause sudden recovery and dangerous behavior. Protective gear, including gloves and long sleeves, was recommended when handling iguanas during collection efforts.

The safest option was to transport animals directly to FWC drop-off sites or leave them undisturbed outdoors. These measures minimized the risk of injury to both humans and reptiles.

Agricultural and environmental effects

The freeze affected not only iguanas but also crops and plant life sensitive to cold temperatures. Citrus growers reported frost damage and potential fruit losses, underscoring the economic impact of the unusual weather event.

While wildlife outside of iguanas was less documented, the sudden cold highlighted how rare freezes can challenge ecosystems adapted to subtropical climates. These events underscore the interconnectedness of environmental and economic systems.

Long-term management considerations

The cold snap prompted renewed discussion about strategies to control Florida’s invasive iguana population.

Experts noted that extreme weather can temporarily reduce numbers, but long-term control still depends on tools like trapping, targeted removal, and habitat management.

Public participation during the freeze showed how community involvement can support wildlife management, and officials say the experience and data gathered will inform ongoing invasive-reptile control efforts.

Recovery and dispersal after the cold

Iguanas that were not collected or euthanized often recovered after temperatures warmed. These animals resumed activity and returned to their habitats, demonstrating the species’ resilience in subtropical climates.

FWC continues monitoring and conducting control efforts, including targeted trapping and public education. The freeze event provided valuable real-world data for future planning.

Lessons learned for community and conservation

The event demonstrated how cooperation between residents and agencies can lead to rapid, effective responses to invasive species challenges. Clear guidance and designated collection points allowed thousands of iguanas to be removed efficiently and safely.

Moving forward, education on invasive species, safe handling, and public participation will strengthen wildlife management. This shared experience highlights the benefits of combining community action with professional oversight.
