Services, Guides, and Information

An arboretum (plural arboreta) is a collection of trees, often with a theme or pattern. Every one of Portland’s parks has its own unique assortment of trees, each with a story to tell. With more than 300 different kinds of trees in Parks, no two Pop-Ups are the same!

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 Parks & Recreation is partnering with the Portland Fire Bureau on a prescribed fire program that will help reduce the risk of fire, reduce the harmful effects from insects and pathogens, and improve the overall health of our park lands.
