Portland Arbor Day

Portland has been celebrating Arbor Day since 1889 - bringing communities together to recognize the importance and value of trees. The trees of our city provide essential services - making a healthier and more equitable place to live for all Portlanders.

Portland Arbor Day 2020 was celebrated virtually on Friday, October 16.

Join us in celebrating our neighbors who dedicate their time to caring for trees and sharing their passion with their community.

Portland Celebrates Arbor Day in October

Due to our changing climate, Portland’s hot dry summers have made it more difficult for trees planted in April to succeed. By moving Arbor Day to October, we can plant new trees and take advantage of our nice wet winter months to help them get established. We are excited about this change and to provide an opportunity to work with Portlanders to plant new trees and give them the best opportunity to thrive.

Share your Tree Story

Is there a tree that is special to you? Honor that tree and share your story at canopystory.org, a website dedicated to collecting tree stories developed by our friends at Portland State University's Institute for Sustainable Solutions. Canopystory.org is a way to share trees stories, find cool trees around Portland, raise awareness of the value of trees in a beautiful city like Portland, and perhaps even preserve magnificent trees from being removed.
