Invasive lizard species could turn Georgia into a breeding ground; efforts mount to eradicate tegus

Argentine black and white tegus are a significant threat to native wildlife in Georgia. The species, the largest of all tegus, can reach 4 feet long and weigh 10 pounds or more.

EXTRA TIME TO MAKE IT TO YOUR DESTINATIONS. IF YOU STAY IN THE TOOMBS AND TATTNALL COUNTY AREA.. THERE'S A SPECIES OF LIZARD LIVING THERE .. THAT'S CERTAINLY RARE TO THIS AREA. AND NOW THE GEORGIA SOUTHERN BIOLOGY DEPARTMENT HAS TEAMED UP WITH THE DEPARTMENT OF NATURAL RESOURCES TO DO SOMETHING ABOUT IT. DAVE WILLIAMS TELLS US ALL ABOUT THE TEGU (TAY-GOO) LIZARD. (:01-:08) (:21-:30) (1:07-1:16) IT'S BEEN QUITE AN EVENTFUL LAST COUPLE OF WEEKS FOR THE FOLKS IN THE BIOLOGY DEPARTMENT AT GEORGIA SOUTHERN UNIVERSITY'S STATESBORO CAMPUS. THEY'VE BEEN ON THE HUNT FOR THE TEGU LIZARD, WHO ARE BEING FOUND IN GREAT NUMBERS IN THE TOOMBS AND TATTNALL COUNTY AREAS. THEY HAVE TRAPPED THEM, IN AN AIM TO CUT DOWN ON ITS POPULATION WHICH CAN BE AS MUCH AS 30 OFFSPRING AT A TIME. (MCBRAYER) "WE'RE WORRIED THAT THEY'LL BECOME A REALLY INVASIVE SPECIES AND BE DETRIMENTAL TO OUR NATIVE WILD LIFE AND SO WE'RE TRYING TO TRAP THEM AND GET RID OF THEM BEFORE THEY BECOME POTENTIALLY A BIG PROBLEM." AND BECAUSE OF THAT THREAT THEY POSE.. WHEN THE LIZARDS ARE TRAPPED, THEY'RE BEING EUTHANIZED, SO RESEARCH CAN BE DONE. (MCBRAYER) "WE'RE LOOKING TO DESCRIBE THE POPULATION, BOTH IN TERMS OF HOW MANY THERE MIGHT BE AND THEN WHAT IS THE HEALTH AND REPRODUCTION STATUS OF THESE ANIMALS, SO WE WANT TO KNOW IF THEY'RE BREEDING, HOW MANY OF THEM MIGHT BE BREEDING, SO THAT WE CAN GET AN IDEA OF HOW BIG A PROBLEM THIS COULD POTENTIALLY BECOME." A HANDFUL OF STUDENTS ARE HELPING DR. MCBRAYER WITH THE PROJECT LIKE JUNIOR MICHAEL BRENNAN AND GRAD STUDENT JADA DAVIS. AND BRENNAN HE DIDN'T REALIZE SO MANY OF THESE REPTILES WERE LIVING NEARBY. (BRENNAN) "I WAS VERY SURPRISED TO LEARN THERE WAS AN ESTABLISHED POPULATION, BUT IT DOES MAKE SENSE THAT THERE HAVE BEEN, THEIR HABITAT IS SIMILAR TO WHAT THEY HAVE IN SOUTH AMERICA, WHERE THEY'RE FROM. I JUST WASN'T EXPECTI

Argentine black and white tegus are a significant threat to native wildlife, from gopher tortoises to ground-nesting birds such as bobwhite quail, wild turkeys and whip-poor-wills.Georgia Southern University professor Dr. Lance McBrayer, who is coordinating the project, said that while trapping will continue at key sites this spring and summer, arrangements of game cameras will also be rotated every few weeks to as many new places as possible."We’re trying to establish if we can reliably detect tegus with this method and also see if the tegus have moved farther away from the main area we’re trapping," he said.If a tegu is spotted, traps will be set to try and catch it.

The Georgia Department of Natural Resources, Georgia Southern University and the U.S. Geological Survey have been working since 2018 to assess and remove what is considered a wild population of Argentine black and white tegus in Tattnall and Toombs counties.
