Park Tree Inventory

Why Inventory Park Trees?

Portland’s parks are an important public resource for residents, comprising almost 200 developed parks, 7,900 acres of natural areas, and an estimated 1.2 million trees. Park trees together with street trees make up the population of trees most accessible to Portlanders, available for all residents to experience and enjoy.

Trees are a vital component of our parks. Conducting an inventory of park trees aids in proactive management that ensures their health and extends their lives while reducing risks to the public. Information collected as part of this inventory will tell us where trees will need to be replaced in the near future, locate space for new planting projects, and which species are most suited to our parks and their many users. 

For some background on Portland's parks, read this detailed report documenting their early history in the Open Space & Park Development 1851–1965 report, or visit our virtual park tree tours, which include historical photos and information on many parks.

How did we do it?

Volunteers and Urban Forestry staff finished inventorying over 25,000 park trees in 2019. Volunteers participated as either Neighborhood Organizers,Team Leaders, Data Collectors, or Arborists-on-Call. More details on volunteer roles are available here.
