Tree Inventory Project

Information
Urban Forestry staff measuring diameter of a street tree.
The Tree Inventory Project collects data on street trees and park trees. By measuring, mapping, and identifying public trees across Portland, we are able to better manage our urban forest.

Starting in 2010, PP&R partnered with communities to measure, map, and identify nearly 220,000 street trees and 30,000 park trees. Information and tools from this project help professionals and community members protect, preserve, and grow our urban forest.
