[RWG] [APWG] Bothriochloa ischaemum invasiveness question

[Wayne Tyson]

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.

  Yellow bluestem (Bothriochloa ischaemum) 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.


  Folks in (www.texasinvasives.org) 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.


  Thank you.
