Good Morning Ms. Kelsey,

I want to thank you for taking the time to report your finding to the Oregon Invasives Hotline. I toured the site you reported and found the tree in question. It is clear that you have spent a good deal of time helping to remove climbing vines from the trees. So thank you for your efforts!

I was able to find the exact tree in question and saw that it had been cut. I was not able to find any new growth or leaves on the vine. As such it is very difficult to determine what species we are dealing with.

That said, I thoroughly surveyed the entire area and found no evidence of kudzu. I did observe a number of climbing vines including English ivy (Hedera helix), Baltic ivy (Hedera hibernica), Old Man's Beard (Clematis vitalba), Poison Oak (Toxicodendron diversilobum), and Wild cucumber (Marah oreganus).

I do not believe the vine in question is any of these species. My best guess is that it may have been a Wysteria vine on the property, that now appears to be dead.

We are currently working with the property owners on others invasive weed issues and will continue to monitor the site.

Once again thank you for your report. Please feel free to contact me if you have any additional questions.

Sincerely,
