Heritage Tree Program

What we do & Program Goals

The Heritage Tree Program is a cooperative program between the City of Seattle and PlantAmnesty to celebrate Seattle's Special Trees.

The program was initiated by PlantAmnesty in 1996, and the city became a cosponsor a few years later. The first Heritage Tree was recognized jointly by the City of Seattle and PlantAmnesty in 1996. There are now many more!

Heritage trees may be on either City or private property. Each candidate tree is assessed by a certified arborist and evaluated by a review committee. Trees can be nominated as an individual or a collection, but must have the owner's approval and meet criteria for health in addition to being selected according to one of the following categories:

Specimen: A tree of exceptional size, form, or rarity.
Historic: A tree recognized by virtue of its age, its association with or contribution to a historic structure or district, or its association with a noted person or historic event.
Landmark: Trees that are landmarks of a community.
Collection: Trees in a notable grove, avenue, or other planting.

Each Heritage Tree owner receives a certificate. Additionally, you may be able to get a plaque for your tree at your cost. If you are interested in a plaque, please contact Plant Amnesty at 206-783-9093.

Check the Seattle Tree Inventory to see if a tree is already designated a heritage tree. All gold tree icons are Heritage Trees. Updated quarterly.

Heritage Trees are not the same as Exceptional Trees of which there are a greater number. Learn more about Seattle tree protection rules.
