I haven't really been following this snail thing too closely, but I would
like to add a comment for thought.
Introducing non-endemic species to an area is not generally a wise thing
to do. The bio-ramifications of such an introduction cannot be predicted
in any way. Even a relatively small introduction (50-100 snails) can have
an enormous impact on the local flora/fauna. One need only look out the
window to see how a very small number of European starlings or English
sparrows have spread to a nation-wide effect on native bird species. Here
in the Great Lakes region, we are currently undergoing an explosion of
purple loosestrife, a non-native weed now extremeley widespread thoughout
most wetlands. The gypsy moth has wreaked havoc for 10 years now. The
zebra mussel, which found it's way here adhered to the hull of ships from
the Atlantic Ocean, is now infesting inland lakes as well, causing a great
shift in the natural balance of these relatively small bodies of water.
The sea lamprey nearly wiped out the entire fishery of the Great Lakes.
The list goes on and on. And for those of you who are avid Simpon's
viewers, remember what happened when Bart let his pet frog go in
Australia. Lord help us!
Furthermore, there are laws that govern the introduction of alien species
in local environments. Violation of these laws generally carries a heavy
penalty, besides the potential damage to the local environment. Check with
your state department of natural resources (or equivalent department) for
further information.
I'll now step down from my soapbox.
