Tree Inventory Project

The Tree Inventory Project is the City’s effort to map, measure, and identify public trees across Portland. Starting in 2010, PP&R partnered with communities to catalog nearly 220,000 street trees and nearly 30,000 park trees. Information and tools from this project help professionals and community members protect, preserve, and grow our urban forest.  

2023 Street Tree Inventory

Over the course of summer and fall 2023, Urban Forestry staff will inventory street trees in 41 Portland neighborhoods. This data collection effort is part of a three year effort (2022 - 2024) to update the canopy database developed from Portland's first complete Street Tree Inventory (2010 - 2016). 

This year, a team of ten seasonal staff will conduct data collection, with project support from a team lead and project manager. A portion of this work will be conducted by the Youth Conservation Tree Crew and there will be opportunities for volunteers to to assist later in the season, as well.
