Commentary

Good Morning Kimberly,

I want to thank you for reporting Kudzu to the Oregon Invasives Hotline. Kudzu is a high priority weed for control and eradication to prevent it from spreading here in Oregon. I was out at the site this week and was able to walk the network of trails.

I saw a lot of climbing vines including two common state-listed noxious weeds English ivy (Hedera hibernica) and Old Man's Beard (Clematis vitalba). The other common vine on site was Wild Cucumber (Marah oreganus) which is a native plant.

Fortunately, I did not observe any Kudzu on site. Based on your description of the sites, it is likely that the vine you are seeing is old man's beard. This common invasive plant is widespread in our area, and we rely upon the actions of local landowners to control these plants when they occur on their property.

Sincerely,
