Volunteers have mapped, measured, and identified nearly 250,000 trees along Portland's streets and in parks.
The Tree Inventory Project is the City’s effort to map, measure, and identify public trees across Portland. Since 2010, PP&R has partnered with communities to catalog nearly 250,000 trees along our streets and in parks! Information and tools from this project help residents better understand the urban forest, and plan for a resilient future.
The Tree Inventory Project is currently on hiatus, and is set to return in Summer 2022. In the meantime, learn about other ways to get involved on our Urban Forestry Workshops page.
