I wasn't sure if I should post this here or in the wildlife forum, but decided here since it's a question about Trail Concerns - the environment.
I've become somewhat interested in worms. I'm quite surprised about how little is actually known about this most useful of organisms. I did read a book on worms from my local library, but left a lot of questions in my mind, looking for another book. However, one intriguing aspect was the apparent damage they are doing to Minnesota's forests. http://www.dnr.state.mn.us/invasives...rms/index.html
But the obvious question is, why just Minnesota? Does anyone know of any other areas, especially along the AT, that the worm is having an adverse effect on the environment?
Also, I find this a little hard to believe, from the above link:
If non-native earthworms are already here, isn't it already too late?
No. Without humans moving them around, earthworms move slowly, less than a half mile over 100 years.
Seems to me it is very dependent on the species, but they just make a blanket statement. It seems to me that the Red Wiggler (or any type worm that inhabits the leaf litter) spreads fairly quickly -- BTW, this is the species (as I understand it) that is used mostly in the composting-type privies. However, that statement may be true with respect to earth-dwelling speicies. But that's just speculation on my part.
