Bob:
I concede that neutral language is more scientific and objective, but
did we catch you in a Freudian slip?
Your statement, "Although this article is not good news," contradicts
your usual stance. Are we, conservation and biodiversity freaks,
getting through to you?
A partial rebuttal to your argument below is that humans aren't the only
judges of ecosystems.

Hi Craig and all,
Replaced is the correct term.
Destroying implies a value judgment that the invasive plants are "bad"
and
the plants that they are replacing are "good". In science there are no
"good" or "bad" plants as there are no "good" or "bad" ecosystems.
Nature
lovers may not like or may not find attractive the ecosystems that
occur,
for example, in a vacant lot in an inner city but that does not make
those
ecosystems "bad'. There are particular ecosystems that humans want to
protect for many reasons and that is fine but these are human value
judgements. If a scientist studying any particular ecosystem did not
know
ahead of time that it was dominated by invasive, exotic plants, it would
be
impossible for he or she to determine if the plants present on site were
native or exotic based on the biology of the plants and their
interactions. Let me cite a real life example to make my point. A few
weeks ago a client called me looking for information on how to eradicate
invasive, Asiatic bittersweet that she had found on her property. I
asked
her if she was certain that it was the Asiatic variety and not the
native
bittersweet. She replied that she no idea how to distinguish them. I
asked
her if it turned out that the bittersweet on her property were the
native
variety, would she still want to eradicate it? Her answer was "of course
not". Her only criteria for wanting to eradicate the plant was the
supposition that it was exotic. In my mind that is not a good reason to
eradicate anything, especaill\y when there are no guarantees that the
plants eradicated will not be replaced by something even less desirable.
When science is reduced to name calling to provoke an emotional
response,
it is not science.
