&gt; _______________
At what point does a plant become invasive?  I think all of our plants have 
come in since the ice age. I even remember a discussion when it was said all 
the worms arrived after the ice age ended.  I think all of the people  came 
later as well. The only ones that are native here are those of us who were 
born here. So also with plants. Where do native plants stop and invasive 
plants start? I think some of these plants hat are being called invasive 
have been around long enough to consider them native.

Roland.
