I've had a couple of researchers speak about this on my show over the years.
They maintain that all of 'our' native worms went extinct during our last
mini ice age (wooly mammouth time), which I find hard to believe.
Anyway, they say earthworms are changing the flora in the forest by
enriching the soil too much for some native plants that love crappy soil.
But I suspect this type of change is and has always been constant--with
species moving in and out, up and down--and have never understood why so
many people seem to think that evolution and natural order should all cease
on their personal 30th birthday.
None of these guys say that worms are bad in gardens or agriculture.
When I've asked what they think people should do about all this, if
anything, they simply ask that people not move worms into the woods.

Subject: [cg] worm ecology
I just returned from a landscape symposium where a Cornell researcher spoke
about the damage worms do to forest ecology. He also mentioned that worms
are not indigenous to North America. Do we know anything about the
implications for our encouragement of worms in the garden for ecosystems
beyond the garden?
