A museum of living trees. Founded in 1928 to conserve endangered species and educate the community, Hoyt Arboretum encompasses 190 ridge-top acres and 12 miles of hiking trails just minutes from downtown Portland.

The Bristlecone Pine trail is a regional draw with recognition in hiking guidebooks. Increasing access and connection to nature at Hoyt Arboretum will support a broader community providing safe, barrier-free, and welcoming ADA access to trails, including access to unique environmental and conservation activities..

This project is funded by the 2019 Metro Regional Parks & Nature Bond Local Share and will renovate the existing 1-mile out and back trail and the parking lot that serves as a trailhead.

Trail improvements will focus on renovating the asphalt surface, removing root heaves and cracks that create barriers to free movement for those with who utilize mobility devices, adjusting the slope to meet new ADA guidelines, creating new places for rest along the trail, and widening the trail surface where allowable. Improvements to gathering areas and key overlooks will be made that focus on connecting people to nature in more meaningful ways and prioritizes people with varying abilities.

Park history

During National Forestry Week in 1928, the Forestry Committee of the Chamber of Commerce convinced the City Council to establish an arboretum in Washington Park to preserve evergreens for educational and recreational purposes. Multnomah County gave the Parks Bureau perpetual use of approximately 145 acres of land north of Washington Park for this purpose. It was named Hoyt Arboretum in honor of Ralph Warren Hoyt, the county commissioner who championed the formation of the arboretum.

Most of the collection is arranged in family groups: all the oaks are in one area and all of the redwoods are in another. Grouping by scientific classification, or taxonomic arrangement, was in vogue when the Arboretum was first laid out. In the 1930s, planners decided to use Fairview Boulevard to divide the conifers from the deciduous trees: conifers were planted on the west side and deciduous trees on the east.

Hoyt Arboretum’s plant collection contains 6,000 individual trees and shrubs, representing 2,000 different species from around the world. A publically available database allows the user to search for plants by family genus, species, common name and location in the arboretum. Plant Database

Condition is rated 1 (good) to 5 (very bad); blank means not yet assessed and is excluded. Park trees are inventoried separately and not counted here. No repair costs — those aren't published.

Repair ledger

Assessment dates are copied from the public Parks Amenities layer. Old dates mean this source does not publish a newer assessment for that asset, not that we have confirmed no newer internal inspection exists. PP&R does not publish itemized repair costs, so this ledger shows needs without dollar figures.
