Overview
Mission
A 24-acre enlargement of the arnold arboretum, a boston city park, was publicly announced on march 13, 1996 by the former mayor thomas m. Menino, the first enlargement of this park in 101 years. The organization is involved in protecting and enhancing public enjoyment in the arboretum lands.
What it reported doing in 2025
In the past year, the arboretum park conservancy (apc) celebrated the new ada accessible arboretum road entrance and tupelo path block with a block party on july 19, 2025. Arnold arboretum partners and eight organizations had tables and engaged visitors about their contributions to getting this project done. The apc prepared two handouts explaining the mission of the arboretum park conservancy and ideas about future projects for extending the blackwell and tupelo paths and adding new entrances for underserved neighborhoods. The tupelo path now welcomes thousands of roslindale residents to the bussey brook meadow and connects to the south street gate, the blackwell path, the Washington street gate, and the forest hills mbta station in jamaica plain.on april 25, 2026, the charles river watershed association and the arboretum park conservancy held a bussey brook meadow cleanup. Energetic volunteers removed invasive species in the oak woods near the south street entrance. On may 2, 2026, the apc hosted a bird walk.this spring, the apc matched funding from the boston parks access fund at the boston foundation for planting and watering eight oaks along the west side of the blackwell path facing the Washington street entrance. Washington street gate improvements are under construction and will be complete in fall of 2025. The apc contributed funds to a new pollinator garden at this location.the apc has coordinated with the arboretum, the boston parks and recreation department, the boston conservation commission, the boston transportation department (btd), the mbta, and walkup roslindale.
