Since in 2010, PP&R has partnered with communities to measure, map, and identify nearly 280,000 street and park trees. Information and tools from this project help professionals and community members protect, preserve, and grow our urban forest.
Street Tree Inventory
Urban Forestry staff completed a re-inventory of street trees in 2024, collecting data on 252,180 trees in citywide rights-of-way. This work was part of a three-year project to update the data from Portland's first complete Street Tree Inventory which occurred from 2010-2016.
In Fall 2024, Urban Forestry conducted a sample survey which estimated approximately 81,000 trees in mostly naturalized rights-of-way not inventoried by the Street Tree Inventory project. Combining data from the Street Tree Inventory and the sample survey, there are an estimated 330,000 street trees in the City of Portland.
