Green Iguana (Iguana iguana) is the most common and widely distributed species in the state of Florida. They are large, bright green and can reach considerable sizes.

Florida, known for its beaches and warm weather, is facing a growing problem: the invasion of iguanas. These large lizards, native to Central and South America, have adapted perfectly to the state's subtropical environment and have become a real pest.

Why are they a problem?
a) Damage to infrastructure: Iguanas dig burrows for shelter and to lay eggs, which can damage home foundations, swimming pools and septic systems.
b) Impact on vegetation: They feed on a wide variety of plants, including native species, which can disrupt local ecosystems.
c) Traffic accidents: Iguanas often cross roads, especially in areas with lots of vegetation, which can cause accidents.
d) Rapid propagation: Due to Florida's warm climate, iguanas can reproduce quickly and in large numbers.

How did they get to Florida?
Many of the iguanas in Florida were introduced as exotic pets and then released or escaped. The state's warm, humid climate provided the perfect environment for them to thrive and reproduce.

What is being done about it?
1-Population control: Programs are being implemented to control iguana populations, including capture and removal.
2-Public education: The public is informed about the damage iguanas can cause and is encouraged not to release them into the wild.
3-Research: Studies are being conducted to better understand the behavior and ecology of iguanas in Florida.

How can you help prevent invasive species and disrupt ecosystems?
1-Don't release exotic pets: If you have an iguana as a pet, make sure it is always contained.
2-Report sightings: If you see an iguana, inform local authorities.
3-Support control programs: Donate to organizations working to control iguana populations.
