<DIV><FONT face=Arial size=2>Check with your highway department (and similar
agencies and entities like ranchers) to see if they've seeded it anywhere. Where
do they get the seed? Try to figure out how the population you know about
might have gotten there. Small colonies might be manageable if you stay on top
of it until it's all gone, but if it's widespread, you may have to live with it.

invasiveness question</DIV>
<DIV><BR></DIV>
<DIV dir=ltr>
<DIV>Yellow bluestem <I>(Bothriochloa ischaemum</I>) is a new species to
Saguaro National Park (Tucson, Arizona). It showed up at an isolated spot in
one of the riparian areas. I haven't been able to find much information about
this plant.</DIV>
<DIV><BR></DIV>
<DIV>Folks in (<A
href="http://www.texasinvasives.org">www.texasinvasives.org</A>) do not seem
to like it. Does any one know how invasive it is? What are the ecological
threats of this plant? Best control measures? Any information you can provide
would be helpful.</DIV>
<DIV><BR></DIV>
<DIV>Thank you.</DIV>
