Current Geographic Range of Burmese Pythons in Florida
Burmese pythons now occupy a vast area across South Florida, with core populations centered in the Everglades ecosystem and surrounding counties. The Florida Fish and Wildlife Conservation Commission reports established breeding populations in Miami-Dade, Collier, Hendry, Monroe, and Broward counties, with sightings extending into Lee and Charlotte counties. Genetic studies confirm multiple independent introductions and a rapidly expanding front moving northward into more temperate regions of the state.
The U.S. Geological Survey and the National Park Service have mapped the python range using road surveys, camera traps, and roadkill data, showing the species now covers thousands of square miles. The most dense concentrations remain within Everglades National Park and Big Cypress National Preserve, where prey density and warm, wet habitat support large constrictor populations. FWC and USGS models indicate the range could continue expanding north into the Florida Panhandle and potentially into neighboring states if climate conditions remain favorable.
Ecological and Economic Impact of the Python Range in Florida
The python range in Florida overlaps directly with critical habitat for endangered species, including the Key Largo woodrat, the Florida panther, and numerous wading bird colonies. A 2023 study published in the Proceedings of the National Academy of Sciences documented severe mammal declines across the python range, with raccoon, opossum, and rabbit populations dropping by over 90 percent in heavily invaded areas. The snakes also compete with native predators such as the Florida panther and the American alligator for prey.
Economically, the python range creates costs for wildlife management agencies, private landowners, and the tourism and outdoor recreation industries. The South Florida Water Management District and the National Park Service spend millions annually on python detection, removal, and research. The presence of pythons also affects property values and hunting leases in infested areas, as declining game populations reduce the economic appeal of traditional wildlife-based land uses.
Control Efforts, Regulations, and Future Outlook
Florida has implemented several programs to manage the python range, including the South Florida Python Elimination Program, which employs professional hunters to remove pythons from public lands. The FWC also allows year-round harvest of Burmese pythons on 25 state-managed lands without a permit or hunting license, and the agency hosts annual challenges with cash prizes for the longest and most pythons removed. Private companies and nonprofit groups now assist with detection dogs, radio telemetry tracking, and research into genetic biocontrol methods.
Regulatory actions at the federal and state level aim to prevent further spread. The U.S. Fish and Wildlife Service listed Burmese pythons as an injurious species under the Lacey Act, restricting their importation and interstate transport. The Florida Legislature has also passed measures increasing penalties for illegal release of exotic reptiles and funding python research.
