Arnold Arboretum of Harvard University

What Arnold Arboretum of Harvard University does

The Arnold Arboretum of Harvard University is a 281-acre living museum of trees and research institution located in Boston's Jamaica Plain neighborhood, founded in 1872 through a bequest from New Bedford merchant James Arnold. It operates as a non-profit institution of Harvard University under a landmark 1,000-year lease signed with the City of Boston in 1883, with the city responsible for infrastructure and Harvard maintaining the collections and programs. The Arboretum curates approximately 16,000 accessioned plants representing one of the world's most comprehensive collections of temperate woody plants, supported by state-of-the-art Weld Hill research laboratories, a herbarium, and extensive library and archives.

The institution offers free daily public access to its landscape and generates engagement through educational programs (Field Study Experiences for Boston-area schools, docent-led tours, Tree Mobs, the Tree seminar for Harvard undergraduates), publications (Arnoldia quarterly magazine since 1911), and digital tools (the Expeditions mobile web app, Arboretum Explorer interactive map, virtual walks). Its core products and services span visitor experiences, K-12 education, citizen science (Tree Spotters partnership with the National Phenology Network), and research resources for international scholars. Revenue streams include membership subscriptions, one-time donations and commemorative gifts, planned giving, capital campaign contributions (the Sesquicentennial Campaign), and nominal event fees.

The Arboretum serves a diverse stakeholder base: general public visitors seeking free urban green space and nature education, K-12 students, Harvard faculty and students, and an international research community. It is led by Director William (Ned) Friedman, the Arnold Professor of Organismic and Evolutionary Biology, with a leadership team of 7 named individuals and approximately 52 employees overall. Recent strategic activity centers on the Sesquicentennial Entrance Improvement Project, including the donor-funded Washington Street Gate renewal nearing completion in 2025–2026.
