DNR looking for input about possible tegus in area


According to a press release sent out Friday, June 25, the Georgia Department of Natural Resources (DNR) is soliciting the help of citizens in a specific area of the state to try and eradicate or, at the very least, control a wild population of Argentine black and white tegus. Though the press release targeted those who live in Toombs and Tattnall counties, residents of southeast Emanuel (around Oak Park, for example) might be of some help as well.

Growing up to 4 feet long and weighing 10 pounds or more, the lizard native to South America is an invasive species that threatens Georgia wildlife.

Tegus will eat the eggs of ground-nesting birds—including quail and turkeys—and other reptiles such as American alligators and gopher tortoises, both of which are protected species. They will also eat chicken eggs, fruit, vegetables, plants, pet food, carrion, and small, live animals from grasshoppers to young gopher tortoises.

There are concerns as well that tegus could spread exotic parasites to native wildlife and cause bacterial contamination of crops. Research shows that these reptiles, like most, carry salmonella.

Early detection, rapid response, and public involvement are key to stopping tegus in the wild in Georgia.

DNR’s Wildlife Resources Division, the U.S. Geological Survey, and Georgia Southern University are trapping tegus, tracking sightings, and assessing the population.

What you can do

If you see a tegu in the wild, alive or dead, contact DNR immediately via www.gainvasives.org/tegu; call 478-994-1438; or email gainvasives@dnr.ga.gov. These reports help biologists document occurrences and respond effectively. Note the location and, if possible, take a photo.

Here are some additional tips:

• Keep pet food inside.

• Fill holes that might serve as shelter.

• Clear yards of debris such as brush piles that can provide cover for tegus.

• Be a responsible pet owner. Do your research before buying an exotic pet, and don’t turn it loose!

Tegus at a glance

• The Argentine black and white tegu (Salvator merianae), largest of all tegu species, is native to Brazil, Paraguay, Uruguay, and Argentina.

• Black to dark gray with white speckled bands across the back and tail, these reptiles can weigh 10 pounds or more and live 20 years. Hatchlings have bright green on their heads, a coloration that fades at about 1-month-old.

• Sizes vary by age. Hatchlings can be about 6 to 8” long. Adults documented in the wild in Georgia have averaged slightly less than 2’.

• Tegus are active by day. These fast-moving, terrestrial lizards are rarely found more than a few feet off the ground, but they are strong swimmers and can stay submerged for extended periods.

• Tegus occupy mixed grassland/woodlands and disturbed habitats such as forest clearings, fence rows, and roadsides. They winter in burrows or under cover in a hibernation-like state called brumation. In Argentina, tegus are found from sea level up to altitudes of 4,100’.

• Adult tegus have few predators and can multiply quickly. Females reach reproductive age at about 12” long or after their second season of brumation. They can lay about 35 eggs a year. Hatching in Georgia would be expected in June/July.

• Tegus are legal as pets in Georgia but it is illegal to release non-native animals into the wild.

• Although not considered aggressive toward people, tegus will defend themselves if threatened. They can react fast and lash with their tails. They have sharp teeth and claws and strong jaws.

• In Georgia, tegus might be confused with native reptiles such as juvenile alligators (which are protected), broadhead skinks and eastern fence lizards (although even as adults, all native lizards would be no larger than a hatchling tegu).

Frequently asked questions about tegus in Georgia

Q: How widespread are tegus in Georgia?

A: Georgia’s only known wild population is in Toombs and Tattnall counties. In 2018, DNR’s Wildlife Resources Division, working with DNR Law Enforcement, began investigating reports of Argentine black and white tegus in eastern Toombs and western Tattnall.

Q: How did they get here?

A: DNR cannot say definitively, but it is likely the tegus in Toombs and Tattnall originated with captive animals that either escaped or were released.

Q: Are tegus a threat to pets?

A: While tegus are omnivores and eat a variety of plant and animal matter, they are not considered a threat to pet dogs and cats. Florida’s wildlife agency—which has been dealing with tegus much longer than Georgia DNR—is not aware of any predatory attacks on pets in that state. However, DNR advises against leaving pet food outdoors: It can attract tegus and other wildlife to your yard.

Q: Could tegus spread to other parts of Georgia?

A: Tegus can brumate (reptile hibernation) during colder months, increasing their likelihood for survival across the state. There is scientific evidence suggesting tegus could spread even to other parts of the southeastern U.S. In Florida, tegus have established three wild populations and are considered a high-priority exotic, invasive animal targeted for removal from the wild.

Q: What is being done to deal with tegus in Toombs and Tattnall or elsewhere in the state?

A: DNR is working with the U.S. Geological Society and Georgia Southern University to trap tegus in the area of Toombs and Tattnall counties, removing animals and assessing the population. Trapped tegus are humanely euthanized and their diet and reproductive status are documented. Also, public outreach is raising awareness of the threat tegus pose and the need to report them.

Elsewhere in the state, DNR is responding to any reported sightings. Rapid response is key to combating the establishment and spread of tegus and other exotic invasive species.

Q: Can tegus be owned as pets?

A: Tegus are legal in Georgia to own as pets and they are popular in the pet trade, but it is illegal to release any non-native animal into the wild without a permit.

Q: Can I kill a tegu if I see it in the wild?

A: Yes. Tegus are not native to Georgia and as a non-native species they can be trapped or killed on private property with the landowner’s permission and using legal methods in accordance with local ordinances, animal cruelty laws and safety precautions.

Q: In the Toombs-Tattnall area, will DNR or its partners remove a tegu from my property?

A: DNR is working with the USGS and Georgia Southern to remove tegus from the wild in the area and will respond to confirmed sightings in the area if possible.
