Commentary
Hey, Steve. Thanks for checking in! We're at the point now of having more knotweed than I can effectively manage. So, most new patches are being noted, but not added to management lists. If you're able to talk to landowners, that's probably the best next step. Feel free to refer folks to me at mitch.bixby@portlandoregon.gov, if they'd like more explanation.
I hope all is well....
