Re: Friendly worms or killer worms???
Nan,
It was the NY Times that brought this problem to my attention a few years ago
and there's been quite a bit written about it since (do a Google on
earthworms forest damage and see what you get!). One learned society concerned is The
Ecological Society of America. The address below is one of the conferences held.

There's a lot of contradictory information floating around on this topic, but
I haven't followed it up. According to one article there are not many (if
any) places in New England where there are still native earthworms due to
competition from European worms. Another article claims there are no native
earthworms because they were wiped out in the ice age. There's a story here somewhere.
I can't prove it but it seems to me that the layer of leaf litter in the
forest property my family has owned for 60 years is not as thick as it used to be.
And the chopped leaf mulch I put down in my garden sure disappears fast. Why
not discuss this more on the Organic Gardening list?
Sally
