Parks Tree Inventory



Why Parks Tree Inventory?

Portland Parks & Recreation lands contain over 1.2 million trees. Portland’s parks are an important public resource for residents, comprising 11,697 acres with 144 developed parks and 7,900 acres of natural areas. Park trees together with street trees make up the population of trees most accessible to Portlanders, available for all residents to experience and enjoy.

For some background on Portland's parks, read this detailed report documenting their early history in the Open Space & Park Development 1851–1965 report. 

Trees are a vital component of our parks. Conducting an inventory of park trees aids in proactive management that optimizes their health, extending their lives and reducing risks to the public. Information collected as part of this inventory will tell us where to focus for succession tree planting, or locate space for new planting projects. We can also determine which parks are at risk for tree loss due to potential pests. 

What’s New?

If you are an experienced street tree inventory volunteer, you are already well practiced in tree identification and measurement of DBH. The Parks Tree Inventory will provide new skills for you to develop. Data will be collected and mapped on a mobile device, and additional measurements will include canopy height measured through the use of an electronic laser range finder.

How does it work?

Volunteers participate as either Neighborhood Organizers,Team Leaders or Data Collectors. More details on volunteer roles are available here.
