Land Plants - invasive

Ivy, English or Atlantic (Hedera helix or Hedera hibernica) on May 29, 2008

Submitter does not have a specimen

Description of specimen

Ivy is wrapped around the trees, and almost to the tops of some of them. There might be another type of vine on some of the trees as well. My fear is it's going to kill the trees if not stopped soon.

Do you have crews that remove the plants or do you leave it to volunteers or boy scout groups to handle the problem?

Dear Cheryl,

Thanks so much for your report of English Ivy! This terrible plant is choking trees and native plants all over Oregon. Unfortunately, those responsible for controlling invasive species on (Oregon Department of Agriculture and local land managers like Soil and Water Conservation Districts) don’t have enough resources to attack all the Ivy in the state – there is just too much! Private land owners are responsible for controlling weeds on their property, but sometimes people don’t do anything because the task seems too daunting or they are unaware of the problem. The silver lining to this gloomy picture is citizen stewardship. There are many dedicated volunteers who join forces to uncover and protect their favorite areas from English Ivy. In some cases, the SWCD can help coordinate the effort and provide resources. If you are interested in joining a local volunteer effort to combat invasive species, or starting your own, there are some excellent websites listed at the end of this email.

We hope you will keep on reporting! By looking for and reporting some of the less abundant, but equally as aggressive, invasive species, we can control them before they become tomorrow’s English Ivy. Check out this website for a list of plants and animals that are priority for early detection and control in Western Oregon:

Thanks again and keep on reporting!
