Green-Wood is a world-renowned arboretum featuring a dynamic living collection of trees and shrubs. Some of Green-Wood’s oldest specimens predate the Cemetery’s founding in 1838, and the collection continues to grow—each new planting is selected for its climate adaptiveness, wildlife value, enhancement of the beauty of the landscape, and resilience. Every year Green-Wood’s living collection is responsible for sequestering 264,000 lbs. of carbon dioxide, removing 12,000 lbs. of pollution from the air we breathe, and mitigating 2,620,000 gallons of stormwater from entering Brooklyn’s overwhelmed combined sewer system.
