Research on Invasive Burmese Pythons in Everglades National Park and the Southeastern United States

The Burmese python (Python molurus bivittatus) is a large constricting snake native to Southeast Asia that can reach a length of more than 20 feet. They are long-lived (15 – 35 years), a behavioral, habitat, and dietary generalist, capable of producing clutches of up to 100 eggs. This invasive exotic species is popular in the pet trade and is now firmly established in Everglades National Park and other parts of south Florida. Wild pythons pose a significant threat to many species of native wildlife. Currently, estimates of population sizes range from 30,000 to over 100,000 snakes. The semi-aquatic python’s diet in southern Florida includes raccoons, bobcats, white-tailed deer, wading birds, and alligators. Such predation has the potential to cause significant ecosystem disruption. The potential for these large snakes to kill humans is real, but predation on humans by large constricting snakes is extremely rare.

Because of the danger invasive pythons pose for many species of native wildlife, including numerous endangered species, and their potential to disrupt ecosystems, scientists are studying these invasive snakes to better understand the impacts they have on native wildlife and to develop methods for controlling their populations. Davidson College Associate Professor Mike Dorcas is collaborating with other researchers on several of these studies, which are listed below:
