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 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. 


2022 Street Tree Inventory

The Tree Inventory Project has returned to update our census of over 200,000 street trees! Over the next 3 years, the Youth Conservation Tree Crew, inventory staff, and hundreds of volunteers will work together to complete this effort. 

Thank you to our many volunteers who came out this summer to make the tree inventory a success! We'll be back in Summer 2023 to count trees in your neighborhood.

Be sure to follow Tree Bark for news on upcoming events, workshops, and more!
