Ecology and Control of Invasive Reptiles in Florida

This project involves ongoing development of tools for the detection and capture of invasive reptiles in Florida, with an emphasis on Burmese pythons (Python bivittatus) and Black and white tegu lizards (Salvator merianae). The goals are to reduce the risk of reptile invasions in high-value resources such as Everglades National Park and the Florida Keys, to access early detection methods of...

Control and Landscape-Scale Suppression of the Invasive Brown Treesnake

The Brown Treesnake is a highly destructive reptile species that has extirpated many native species of birds, bats, and lizards from the U.S. Territory of Guam. For more than two decades branch scientists with the Invasive Reptile Project have developed, validated, and tested the feasibility of Brown Treesnake control and suppression at various spatial scales.
