An invasive species of carnivorous tree frogs that feed on local flora and fauna are actually breeding in Georgia, an indication that the amphibians have won a more potent foothold within the state, biologists say.
Cuban treefrogs, Osteopilus septentrionalis, are a most commonly canopy-dwelling species local to the Caribbean. It’s unclear precisely once they made the bounce around the Straits of Florida, however the species used to be first documented in Florida within the mid-1900s.
Within the a long time since, the frogs have unfold around the Southeast and past. They have been found out in Georgia in 2004, however have been most likely within the southern a part of the state lengthy ahead of that, stated Daniel Sollenberger, the state herpetologist and a senior flora and fauna biologist with the Georgia Division of Herbal Sources (DNR).
Cuban treefrogs can succeed in 5 and a part inches lengthy—sufficiently big to hide maximum of an grownup human’s hand and far better than any of Georgia’s local tree frogs. And the frogs will consume “the rest they may be able to put of their mouth,” Sollenberger stated, from bugs and lizards to different tree frogs or even small rodents.
Closing 12 months for the primary time, a breeding inhabitants of the frogs used to be found out in a pond alongside the Georgia coast, Sollenberger says. Breeding populations imply extra folks—and extra alternatives to unfold.
Sollenberger says Georgia’s cold winters have to this point restricted the frogs’ proliferation out of doors of advanced spaces alongside the coast. To continue to exist, the frogs keep as regards to civilization, using out the iciness months in artificially heated environments, like transformer packing containers or underneath constructions.
However Georgia, like the remainder of the planet, is heating up because of human-caused local weather trade. The warming development is maximum pronounced within the iciness months, and within the long-term, Sollenberger stated it’s imaginable the frogs’ territory may just enlarge.
With the frogs interested in the heat of campers, RVs and different modes of transportation, it’s imaginable that a success stowaways may just build up numbers out of doors of the coastal spaces the place they’re maximum commonplace these days.
For now, Cuban tree frogs are principally a risk to yard populations of local amphibians. And in comparison to different invasives, just like the Argentine tegu, the frogs are a ways much less problematic. If the tegus—which feed at the eggs of local birds and reptiles—are a 9 on a scale of one–10, the frogs are a 4, Sollenberger stated.
“Cuban treefrogs are relating to, however they’re a far off 2d on account of their reliance on human habitation,” he stated.
Sollenberger stated DNR want to take away the frogs from the panorama and inspired Georgians to report sightings.
