[APWG] [Aliens-L] Ecosystem Restoration or CONTROL? Re: FW: host specific biological controls of Japanese Stiltgrassand other non-native invasive species.

Wed Feb 13 12:43:03 CST 2013

"But until ecologists and other biologists collect, store, and model data
on the ranges of limitations and requirements that characterize organisms,
they will be consigned to guesswork, based on anecdotal observations of
cause and effect, often forgetting that correlation is not always
causation, and certainly is not the whole picture."

I am sorry, but this seems like building up straw men and knocking them
down for fun.

After all, precisely which "ecologists and other biologists" "often forget that
correlation is not always causation"  Can you think of ANY actual people in
the field who this applies to?  Even one?

For many invasive species, ecologists and other biologists have moved
wellpast guesswork and anecdotal observation.
There is a whole lot of data already collected and stored and models built.
Are you reading the scientific literature on invasive species?  I think you
might be surprised that those you paint with your broad brush are actually
making good progress.
