Wisconsin Ecologist Brad Herrick on How to Spot Invasive Species Jumping Worms

Earthworms are good for the soil, but so-called Jumping Worms, an invasive species from Asia, can devastate gardens and forests. Jumping Worms are spreading across North America. “Invasive species can really quickly do a number on native species that don't have defense mechanisms against their invader,” said Brad Herrick, an ecologist at the University of Wisconsin-Madison Arboretum. Herrick told Inside Edition Digital, “It's still early in the invasion, but it's happening fast."
