The History of Iguanas in Florida
Iguanas, a type of lizard native to tropical regions of Mexico, Central America, and South America, have found a new home in Florida. But how did these non-native reptiles end up in the Sunshine State?
The iguana’s invasion of Florida can be traced back to the 1960s and 1970s, when pet owners would bring them into the state. Some iguanas were also intentionally released into the wild by their owners, who could no longer care for them or were looking to create breeding populations. While iguanas are still popular pets today, they are now illegal to release into the wild in Florida.
Over time, these iguanas have established themselves in the state’s tropical and subtropical habitats, including urban areas like Miami and Key West. They are most commonly found in southern Florida, where temperatures are warm and there is ample food and shelter.
- The first iguanas were sighted in Florida in the 1960s and 1970s, introduced by pet owners.
- Escaped and released pets helped establish breeding populations in the wild.
- Iguanas are now illegal to release into the wild in Florida.
While the iguana’s presence in Florida may seem harmless, these invasive reptiles can cause damage to both the environment and infrastructure. They dig burrows that can undermine seawalls and building foundations, and can also damage native vegetation by consuming flowers, fruits, and young leaves. Additionally, iguanas can harbor diseases that can be transmitted to humans and other animals.
| Impact of Iguanas in Florida | Description |
|---|---|
| Environmental Impact | Iguanas can damage native vegetation and compete with native species for resources. |
| Infrastructure Damage | Iguanas dig burrows that can undermine seawalls and building foundations. |
| Public Health Concerns | Iguanas can carry diseases that can be transmitted to humans and other animals. |
Efforts to control the iguana population in Florida include trapping and removing the reptiles, educating pet owners about responsible ownership, and enforcing laws prohibiting the release of non-native species. However, these measures may not be enough to fully address the problem. As with many invasive species, prevention is key, and it is important for pet owners and the public in general to be aware of the potential risks associated with exotic pets and to responsibly care for and dispose of them when necessary.
Iguanas as an Invasive Species
When we talk about invasive species, we refer to a non-native plant or animal species that has a negative impact on the environment, the economy, or human health. In Florida, iguanas are considered an invasive species. They were not originally found in the state, but they have managed to establish themselves and thrive in the wild.
- The first iguanas in Florida are believed to have been introduced in the 1960s by pet owners who released them into the wild. Over time, the population of iguanas grew, and they are now found in almost every part of Florida where the climate is warm enough.
- Iguanas are herbivores and can consume large amounts of plant material. This has led to them becoming a major pest for many farmers and gardeners in the state. They have been known to destroy gardens, landscaping, and crops.
- Another problem is that iguanas are carriers of various diseases, some of which can be transmitted to humans. For example, Salmonella is commonly found in the feces of iguanas, and humans can contract the disease through contact with contaminated surfaces or direct contact with the animal.
The Florida Fish and Wildlife Conservation Commission (FWC) considers iguanas to be a high-priority invasive species, and they have implemented several measures to control their population. For example, it is illegal to release iguanas into the wild, and they can only be owned as pets with a special permit. The FWC also encourages property owners to remove iguanas from their land through humane methods, such as trapping and relocation.
Despite these efforts, the iguana population in Florida continues to grow. In fact, a recent study by the University of Florida found that the number of iguanas in the state has increased by over 300% in the past decade. It is clear that more needs to be done to control this invasive species and protect Florida’s ecosystem.
| Common name: | Green iguana |
|---|---|
| Scientific name: | Iguana iguana |
| Native to: | Central and South America |
| Introduced to Florida: | 1960s |
| Diet: | Herbivorous |
| Reproduction: | Egg-laying |
The introduction of iguanas to Florida is a classic example of how non-native species can disrupt an ecosystem. They may seem harmless, but the impact they have can be significant and long-lasting. It is important that we continue to monitor and control their population to prevent further damage to the state’s environment and economy.
How Iguanas Adapt to Florida’s Climate
When iguanas first arrived in Florida, they were primarily pets that escaped or were released by their owners. However, they have now established themselves as a non-native species and have adapted to Florida’s unique climate in several ways.
- Iguanas modify their behavior to cope with seasonal temperature changes. During the cooler months, they thermoregulate by basking in the sun or taking shelter in burrows to maintain their body temperature. In the warmer months, they will remain active for longer periods of time and bask in cooler, shaded areas to prevent overheating.
- These reptiles are also able to adapt their diet according to the available food sources in Florida’s subtropical ecosystem. While some iguanas are primarily herbivorous, they will also opportunistically consume insects, eggs, and small vertebrates. This allows them to survive on a variety of food sources that are found in Florida’s diverse habitat.
- Another unique adaptation of iguanas is their ability to handle salt. With Florida being situated near the ocean, saltwater is a common occurrence. Iguanas have developed “salt glands” in their heads that allow them to expel excess salt from their system, thus preventing salt buildup that can be harmful to their organs.
While iguanas are not indigenous to Florida, they have adapted to the state’s climate in impressive ways. Their ability to modify their behavior, diet, and physiology has allowed them to thrive in Florida’s subtropical environment, making them a formidable presence in the state’s ecosystem.
In summary, the iguanas in Florida have adapted to the state’s climate in several ways. They modify their behavior in response to seasonal temperature changes, adapt their diet to the available food sources, and have developed salt glands to handle the state’s salty environment. These adaptations have allowed iguanas to establish themselves in Florida and contribute to the unique ecosystem of the state.

The Impact of Iguanas on Florida’s Ecosystem
As non-native species, iguanas are having a significant impact on Florida’s ecosystem. Since they were brought over as pets, iguanas have since been released into the wild. Over the years, the iguana population in Florida has exploded, leading to various issues.
- Destruction of vegetation: Iguanas are primarily herbivores, which means that they eat a lot of vegetation. This behavior can cause a significant impact on the plant life in the areas where they are present. Iguanas have been known to strip trees of leaves and chew through flowers, among other things.
- Predator effects: The presence of iguanas can also have an impact on other species in the ecosystem. For example, they provide a food source for certain predators, which can lead to an increase in their numbers. These predators, in turn, can impact the population of other species in the ecosystem.
- Damage to infrastructure: Iguanas also cause damage to infrastructure. They can dig burrows that can weaken foundations and damage sidewalks, patios, and even pool decks.
To get a better understanding of the impact of iguanas on Florida’s ecosystem, take a look at the table below:
| Impact | Description |
|---|---|
| Destruction of vegetation | Eating of leaves and flowers of trees and plants, leading to damage and devastation of the plant life |
| Predator effects | Increase in numbers of certain predators that feed off iguanas, leading to a decrease in other species |
| Damage to infrastructure | Digging of burrows that can weaken building foundations and damage sidewalks, patios, and pool decks |
The impact of iguanas on Florida’s ecosystem cannot be overstated. They have become a nuisance and a danger to the environment, and it is up to us to find ways to manage their population and mitigate their effects.

Iguana Breeding Habits and Reproduction in Florida
Florida’s warm climate and lush vegetation have welcomed various species of reptiles to call it home, but one particular type, the Green Iguana, has thrived in the state’s tropical climate. However, the question remains, how did iguanas get to Florida?
It is believed that Green Iguanas were introduced to Florida unintentionally through the exotic pet trade. Many pet owners release their iguanas once they outgrow their cages or become too hard to handle. These iguanas then found perfect breeding grounds in Florida’s tropical environment, leading to the population growth of iguanas in Florida.
Iguana Breeding Habits
- Iguanas reach sexual maturity at around 2-3 years of age.
- Males will begin to display territorial behavior during the breeding season, which runs from January to March.
- During this time, the male’s dewlap, a flap of skin under their chin, will increase in size and color, and they will exhibit head-bobbing behaviors to attract females.
- Females will lay between 20 to 70 eggs, which will take approximately 65 days to hatch.
- Iguanas do not provide parental care to their young.
- Green Iguanas have been known to breed throughout the year in Florida, which can lead to the exponential growth of their population in the wild.
Reproduction in Florida
The Green Iguana population in Florida has experienced significant growth since their introduction in the 1960s. It is estimated that there are now over 400,000 iguanas in the state. This growth has been attributed to their adaptive nature and ability to breed year-round in Florida’s warm climate, along with the lack of predators and their easy access to food.
The increase in iguana population has caused several concerns for Floridians, including damage to the state’s ecosystem and infrastructure, as well as posing a potential threat to humans through injury and the transmission of salmonella.
In Conclusion
The Green Iguana population in Florida is a prime example of the unintentional consequences that can arise from the exotic pet trade. Understanding the breeding habits and reproductive patterns of these iguanas is crucial in developing effective management strategies that will control their growth and prevent further damage to Florida’s ecosystem.
