Python Invasion Threatens Endangered Woodrat Survival
24 Jun
Summary
- Invasive Burmese pythons are pushing Key Largo woodrats toward extinction.
- A Category 4 hurricane helped pythons spread to Key Largo's isolated habitat.
- Woodrat density has dropped over 80% in seven years due to python predation.
The Key Largo woodrat, an endangered species for millennia, faces extinction due to the invasive Burmese python. This unique island inhabitant builds large, multi-generational stick nests that support other wildlife. Its population has drastically declined, with density dropping over 80% between 2017 and 2024.
Originally from Southeast Asia, Burmese pythons entered Florida via the pet trade and established breeding populations in the Everglades by 2000, decimating native wildlife. A key turning point occurred in September 2017 when Hurricane Irma, a Category 4 storm, likely transported pythons to Key Largo.
Post-hurricane, python detections and breeding on Key Largo surged. A 2026 study documented the woodrat's rapid decline, attributing it to python predation exacerbated by the hurricane's impact. Researchers fear extinction within two decades if python populations aren't managed.
Conservationists are employing innovative methods, like tracking pythons via collared opossums, to combat the invasion. However, the scale of the problem is immense, with no current tools capable of controlling pythons landscape-wide.
