What Is an Invasive Python in Florida
The Burmese python (Python bivittatus) is the primary invasive python species in Florida. It was first documented in the wild in south Florida in the 1970s and is now established across a large area of the Everglades ecosystem. The U.S. Geological Survey lists it as one of the most destructive invasive species in the state. Forbes reports that invasive species cost the U.S. economy billions annually.
Florida's climate and habitat closely match the Burmese python's native range, allowing it to thrive in wetlands, prairies, and hammocks. The species is a generalist predator that consumes mammals, birds, and reptiles. Genetic studies confirm multiple introductions, likely from released or escaped pets and breeding facility escapes. The USGS tracks python distribution and risk mapping.
Ecological and Economic Impact of Invasive Pythons in Florida
Research published by the U.S. Geological Survey and the Florida Fish and Wildlife Conservation Commission shows severe declines in mammal populations in areas with high python density. Road surveys in Everglades National Park documented drops of over 90 percent for raccoons, opossums, and rabbits since the early 2000s. The pythons also compete with native predators such as the Florida panther and alligator for prey.
The economic impact includes costs for management, research, and loss of tourism revenue linked to degraded wildlife viewing. The Florida Fish and Wildlife Conservation Commission coordinates removal programs and public outreach. The FWC page details python reporting and removal incentives.
Current Control Measures and Regulatory Status
Florida allows year-round hunting of Burmese pythons on designated lands without a permit. The state runs the Python Elimination Program, which pays trained contractors to remove pythons from public lands in south Florida. As of the latest public data, the program has removed tens of thousands of snakes since its launch.
Federal and state regulations restrict the importation and interstate transport of Burmese pythons and several other large constrictors under the Lacey Act and the U.S. Fish and Wildlife Service's Injurious Wildlife listing. The U.S. Fish and Wildlife Service Injurious Wildlife list provides the regulatory framework. The FWC page details python reporting and removal incentives.
