Heritage Trees are trees that have been formally recognized by City Council for their unique size, age, historical or horticultural significance. Once accepted by Council, Heritage Trees are designated with a small plaque and listed in the Heritage Tree database.
There are over 300 Heritage Trees throughout Portland, and new trees are added each year. Anyone can nominate a Heritage Tree! Heritage Trees are protected by City Code; once designated, no Heritage Tree can be removed without the consent of the Urban Forestry Commission and the Portland City Council.
Visit this page to see a list of all of the Heritage Trees, including the ones that have been removed from the list. Trees are listed by the year they were designated and also include locations or addresses when available.
Heritage Trees sorted by scientific name, with links to species and tree information.
The nomination deadline is May 1 each year. It takes about a year to receive Heritage Tree designation once the nominated tree has been accepted.

Announcing a new interpretive walking tour of 10 downtown Heritage Trees: From Stumptown to Treetown: A Field Guide for Interpreting Portland’s History though its Heritage Trees.

Can I Prune or Remove a Heritage Tree?
A permit from Urban Forestry is required before pruning, applying chemicals or doing any other tree work on a Heritage Tree, whether the tree is in the City right-of-way or on private property. A site visit by an Urban Forestry Tree Inspector is required before a permit can be issued for Heritage Tree work.
A Heritage Tree can only be approved for removal if it is dead, dying, or dangerous. The Urban Forestry Commission and Portland City Council must formally decommission the tree before a permit can be issued for removal.
Heritage Trees and Development
Heritage Trees must be protected during development. Work on or around any Heritage Tree requires the property owner or applicant to schedule an assessment meeting with the City Forester by calling 503-823-TREE (8733). For permit approval, Planning & Zoning needs to see the recommendations that Urban Forestry provides for the tree transferred on to the tree preservation plan. It is recommended to take a copy of the current plan to the onsite meeting with Urban Forestry. The onsite meeting should be scheduled early in the development application process.
