Invasive Earthworms in Northern Hardwoods Forests
There are no native terrestrial earthworms in most of the northern U.S. and Canada. During the glaciation of the last Ice Age, any earthworms that might have lived in this region died.[1] Thus, the earthworms that we see...

I read your article Chomp. I didn't know earthworms weren't native before reading it. Tks to both you and amelanchier for waking me up.

"There are no native terrestrial earthworms in most of the northern U.S. and Canada. During the glaciation of the last Ice Age, any earthworms that might have lived in this region died."
this has me wondering. i've found worms in sandy soil above the 60th parallel in previously glaciated areas. the remote location, population base and lack of agriculture suggests to me that perhaps this fairly broad statement: 'any earthworms that might have lived in this region died' might be a bit misleading. i don't mean to take away from the problem of invasive species. i just wanted to emphasize that northern Canada is a very large 'region' with many unique and relatively unstudied ecosystems. *fwiw - the worms were found quite deep, almost a foot iirc, and under an area of bunch grass. i always assumed they were nightcrawlers but now i wish i took pictures. **i'm still wondering about this  the ice-free corridor between the two ice sheets from northern Canada into Montana might account for earthworms found near the corridor |

Could be the deer. I saw a program about the variety multicolor trees declining in New England due to deer not having enough predators anymore and eating the seedlings. Could be a link. It showed that acreage blocked off from the deer grew the multicolor tree seedlings where as areas without fencing had none.

I feel sorry for your poor northerners without earthworms. I grew up knowing that earthworms are a gardener's best friend. Now, after hanging out with y'all, I know that the right earthworms are a gardener's best friend. Didn't know there were bad ones before.

I was very surprised when a fellow lepidopterist told me a few years ago about how worms were messing with northern hardwood forests. She sent me the first article that amelanchier linked, which taught me the word "duff."
A few years ago, Ohio State researchers figured out that European night crawlers were responsible for planting ragweed seeds in the US. Blame Your Allergies on the Earthworm |
