The Acton Arboretum is situated on 65 acres of town conservation land in the heart of Town Center, Acton, Massachusetts. Each garden and collection in the Acton Arboretum is designed with a particular purpose in mind. The introduced trees and shrubs in the Arboretum are not arranged in a formal collection, but rather placed informally throughout the developed areas, especially among the gardens and collections. Overall, the arboretum's management and continued development follows this "naturalistic" approach rather than a formalized planting scheme. Many factors are essential to understanding and developing our "naturalistic" arboretum, including the interaction and sustainability of various wildlife habitats and corridors and the diversity of topographical, hydrological, and geological elements in the area. The incorporation of universal design to host visitors of all abilities is an ongoing endeavor.
