So these worms wiggle about some, never knew the could actually "Fly"?
These worms live in the top few inches of soil, so I read. Yet, they are able to destabilize the soil to such a depth that large trees just topples over?
I suppose they can eat an entire compost pile over night?
I think we need some more science and less rumors.
I am finding a lot of articles about these worms but very little useful truthful information.

If you need some science, Wisconsin DNR is involved:

Thanks,
I have read that article, and dozens more like it. I suppose as for as forests in the north are concerned these general statement articles are of some use.
How depleted of nutrients are these worm castings? Exactly which nutrients are they actually depleted of? Are the nutrients destroyed forever, or just temporarily locked up?
If this soil that looks like coffee grounds (like the coffee grounds we add to the garden) is bad for understory plants in the forest, how does it work for plants in the home garden? They normally state in these articles how this soil is very easy to erode away, how does it work in clay soil if dug in? If other organic matter is added to cover it how does it perform?
All these articles are geared toward protecting the northern forest, and I understand that. I am just saying surely there must be some efforts made to understand the benefits these worms might provide in other areas?

There are two professors listed on the back that you could direct your inquiries to and see if they will provide you answers to your questions or reach out directly to the Wisconsin DNR or University of Minnesota Extension. Perhaps these could be good sources for the answers you seek for your garden and compost. I have emailed professors with such niche questions with success in the past, hopefully this will help you out. They are generally more than happy to help as they want to keep invasives at a bare minimum.

That is a great suggestion, I fear however that they are focused on the forests, but it won't hurt to try. I guess I should also reach out to my own Ag University in the state, Auburn University, and my local county agents and see if they can give me any local advice on these worms.

Sounds like a good idea. If you can't find someone at university level who specializes, then I'd ask the county ag agent who should have people on their lists. I know I've picked UWMadison's entomology guys brain many a time. They are full of info and resources. And yes our northwoods forests are way important from hardwood harvest, paper to recreation and fall color. We'll keep them growing safely! Good luck!

Do you know of any companies, providers, farms etc that sell baked garden soil that is jumping worm free. Thank you. Much appreciated.

I am concerned about purchasing compost or soil from outside of MN. I save all veg scraps and newspaper for composting so I don't have to buy it.
