Did you know that Boston’s Arnold Arboretum was established in 1872, making it the oldest public arboretum in North America?
Boston is one of only two cities in the nation to have green space within a 10-minute walking distance for all residents, regardless of income, age or ethnicity, according to The Trust for Public Land. In addition to providing historic and ecological value, exposure to green space improves physical and mental health. The Alliance engages with potential impacts on public assets like Boston Common, the Emerald Necklace, and the Arnold Arboretum to ensure their protection for all Bostonians.
