Invasive Jumping Worms Have Been Found Across the Country—Here’s What You Need to Know
just reported that plant sales in several parts of the state have been canceled because of the Asian jumping worm.Asian jumping worms are native to eastern Asian, making them an invasive species in the U.S., says Howard Russell, M.S., an entomologist at Michigan State University.
: They can harm ecosystems. “They devour organic material in soil, leaf litter, and mulch and poop out grainy, hard little pellets that offer very little to the ecosystem,” Russell says. “The pellets or castings do not breakdown easily, which leads to poor soil structure and less available organic material for plants.”
“The worms can deplete thick layers of leaf litter that serve as rooting media thereby, disrupting the natural decomposition of leaf litter on forest floors and turning the soil into grainy, dry worm castings that cannot support understory forest plants,” the CDFA report says. “They can alter forest soils from a fungal to a bacterial-dominated system which speeds up the conversion of leaf debris to mineral compounds thereby robbing plants of organic nutrients.
