Step 1

Save us a cookie: The very best sample would be a cookie from the tree, which is a 1”-3” thick round (or cross-section) of the trunk taken as close to the base as possible that includes the center and the bark. There’s no rush to help so long as you have time to save a piece of your oak or oaks as you clean up. Along with your cookie, we would appreciate the following information documented on a piece of paper in a plastic baggie thumbtacked to the cookies:

  • Your name and contact information (phone, email)
  • Where the tree was located (street address, cross streets, GPS coordinates).
  • Location of the cookie on the oak trunk (2’ above the base)
  • The diameter of the tree measured at 4.5 feet above the base of the tree (if possible)
  • Any history of the tree, in particular, we would like to know if there might be root rot, if the oak was irrigated, etc. (Note we are also interested in the story of your oak -- and are collecting that information on line - see below)

Drop off: Leave cookies any time in front of the Olin Science Building at 180 Winter Street SE and pile them along the grass of the north entry wall.

Pick up: Send an email to and we will be happy to come to collect cookies from you. You may also call our lab at 503-370-6604. Please leave us a message including the best way for us to get in touch with you.

Step 2:

Share the story of your oak tree. We are also interested in learning about the history of your oak tree, what it has meant to you, and how the storm damage has affected you. We’d like to gather these stories and post them along with photos of your oak trees on this web page. If you are interested in participating, please contact us at the email for phone number above.
