Hi Chris,

Thanks for reporting knotweed. This looks like a high priority infestation. I will investigate how it can be responded to.

Hi Again, Chris.

I wanted to update you on the status of your knotweed report on the Rogue. It turns out that knotweed is unfortunately already fairly abundant along the Rogue river, but Robin Taylor-Davenport, Botanist/Noxious weeds Coordinator at the BLM in the Medford District does organize periodic knotweed control river-float work parties. Your report is very useful as Robin plans her next float.

Thanks again, and keep up the good work!
Tania
