Don't you hate it when Mother Nature changes thingsG?

Can definitely be a bit disruptive.

FWIW, in this case it isn't momma nature that made the issues crop up -- it
was man. The earthworms were added to the system by anglers dropping bait,
in tire treads, soil dropped, and so forth.

It is amazing though what something as simple as a worm can do to an entire
ecosystem when introduced and unchecked.
