Georgia wildlife officials are urging residents to kill invasive Argentine black-and-white tegus spreading across the state [1, 2].
These large predators threaten the local ecosystem by preying on the eggs and young of native species. Because they disrupt native food webs, their presence poses a significant risk to protected animals, and ground-nesting birds [1, 3].
Wildlife officials have documented more than 20 [1] of these invasive lizards in the wild. The reptiles are particularly dangerous due to their size and adaptability, with some individuals reaching up to four feet long [3].
Sightings have been concentrated in Southeast Georgia, specifically within Toombs and Tattnall counties [4]. The lizards are described as fast-moving predators capable of consuming a wide variety of prey, which allows them to thrive in the region's environment [2].
State officials are calling for public assistance in removing the animals to prevent further population growth. The effort aims to protect the biological diversity of the region before the invasive species can establish a permanent, larger foothold in the wild [1, 2].
Argentine black-and-white tegus are not native to North America. Their arrival in the U.S. often results from the illegal pet trade or accidental releases, leading to the colonization of new territories where they have few natural predators [3].
“Invasive tegu lizards are preying on eggs and young of native species.”
The emergence of Argentine black-and-white tegus in Georgia represents a critical biosecurity challenge. As generalist predators, these lizards can outcompete native reptiles and decimate ground-nesting bird populations, potentially leading to a permanent shift in the regional ecological balance if not contained quickly.
