Dear Mr. Cottrel,

Thank you for submitting your report to the Oregon Invasive Species Hotline. Unfortunately, the cost to control weeds often exceed the resources available for this effort. As such, we must prioritize the species and areas we treat to maximize the benefits from our limited resources. Your report helps with this process, and allows us to plan future treatments as additional resources become available. So thank you for your report.

Old Man's Beard is certainly a difficult species to control, and requires specific control measures to effective. For more information, check out the Old Man's Beard factsheet developed by the Four County Cooperative Weed Management Area. (http://cwmatest.files.wordpress.com/2012/11/clematis.pdf)

There are organizations working in this area to control invasives. I referred your report to the North Clackamas Parks and Recreation District that oversees management of Kronberg Park. They have been actively working in the park for the last couple of seasons and are actively working to control this invasive Clematis.

SOLVE is another organization actively controlling invasive species as well as working to restore natural areas and open spaces. Check their website for volunteer opportunities going on throughout the state (http://www.solv.org/get-involved/event-registration).

Once again thank you for your time and effort in reporting this species.

Sam
