Hoyt Arboretum Friends partners with Portland Parks & Recreation to support Hoyt Arboretum, a living museum of trees in Washington Park, Portland, Oregon. Located on 189 acres, the arboretum offers year-round access to 12 miles of trails and is home to more than 2,300 plant and tree species from around the world. Free to the public, it draws about 500,000 visitors each year who use the space for learning, recreation, and quiet reflection. Public programming centers in the Visitor Center and the Bill deWeese Classroom, where guided tours and expert-led sessions cover topics from wildlife tracking to botanical illustration. The Magnolia, Maple, and Conifer collections are nationally recognized, and at least 67 species are listed as rare or endangered in the wild. Hoyt Arboretum Friends, a membership-based nonprofit that operates in partnership with Portland Parks & Recreation, supports conservation, community science, and accessible education through donations and advocacy; a noted recent development is a 2020 partnership with Confluencecenter to advance park equity for Portlanders.
