Ecosystem "health" is a broad term, but are broad terms necessarily
invalid or lacking in utility? If it is "weak," let us explore the
reason why it is so. And, let us find another that is stronger. Is
it (whatever term is best) necessarily--or at all--equivalent to
"greater diversity?" Are

Unfortunately the real issue is not whether a species is invasive but
whether it is charismatic. Cats, mustangs, and even panda bears if they were
released into the wild and could survive in N. America, are charismatic.
Whether they fit into the ecosystem is politically irrelevant.

I must in turn respectfully disagree that "introduced species are bad, no
ifs, ands or buts." Here in Vermont, our lilacs and our red clover are both
non-native (if you want to look at 1492 as the 'cut-off' for determining
"native-ness"). The red clover is our state flower, and the
