Listen: Earthworms Aren't as Good for the Soil as You Think
"Can be good for the planet. But only if they're in the right place, and we'll tell you how you can help your local parks by knowing what to do about them earthworms have long been considered a gardener's best friend since they can help aerate and enrich the soil and even help the planet as a whole the problem is that most earthworm species you'll find in North America. Also happen to be invasive pests that are a threat to hardwood forests. Yeah. Here's a fun. Fact, if you live in North America, you've probably never seen a native earthworm most of the native earthworm species around here were killed off during the last ice age, but earthworms from Europe. Up started to show up with settlers in the sixteen hundreds hitchhiking and ship's ballast and the soil of imported plants and today, a global economy brings soil mulch and fishing bait from all over complete with foreign worms from Asia Europe. And elsewhere writing aboard meanwhile for nearly ten millennia the forests of North America evolved to get along without earthworms trees and smaller plants rely on the thick layer of dead and partially. Decomposed leaves that blankets the forest floor to help them grow and protect their routes. That's kind of a problem since earthworms happen to love chomping through leaves. That's why a lot of forests that used to have a thick organic carpet. Now have bald spots which leads to decimated. Herb species and hardly any tree seedlings taking root. Researchers say earthworms also lead to a decline in populations of salamanders songbirds and orchids to name a few and they're also linked to the growth of invasive plant species. Not all earthworms are bad. According to scientific American only about sixteen of the European and Asian species are responsible for a lot of the damage, but once those worms have moved in. There's no getting them out the best hope is to keep them from spreading. And that's why you should check your local parks or natural resource department to see how you can help. If you spot one"
