The Arboretum’s mission—to encourage the planting and conservation of trees and other plants for a greener, healthier, and more beautiful world—has never been more important. The world around us is not as green as it used to be.
Since the Arboretum’s beginning in 1922, practical, scientific research has been a cornerstone activity. Here, we strive to understand how to grow healthier trees and to create healthy tree communities all over the world so the planet can thrive.
