Hurricane Helene may have swept a wave of invasive species into Georgia in 2024

Dorothy and Toto aren’t the only ones known to hitch a ride on a passing severe weather event.

A map from the U.S. Geological Survey finds that there are 222 possible non-native species that had the potential to spread in Georgia and Florida due to storm-related flooding from Hurricane Helene, which devastated southern states including Georgia in September. The list includes 90 species considered invasive and likely to spread via flood waters.

And while the famous Kansas duo’s trip to the magical land of Oz was bad news for the Wicked Witch of the East, these out-of-place critters are potential problems for all Georgians, said Mike Worley, president of the Georgia Wildlife Federation.
