About Portland Heritage Tree Program

The Heritage Tree Program recognizes and celebrates grand trees of Portland. Heritage Trees stand out among the urban forest for their outstanding size, age, historical, and horticultural significance. Once designated, a Heritage Tree enjoys the highest level of protection by City Code and cannot be removed without consent of the Urban Forestry Commission. 

Each year the Heritage Tree Committee reviews nominations from across the City and makes recommendations to City Council. The program is managed by Portland Parks Urban Forestry and the Heritage Tree Committee, which consists of volunteers who love to look at, think, and talk about trees. The Heritage Tree Committee members work together to review nominations, monitor tree conditions, and talk to the public about Heritage Trees.
