Casey Trees is a Washington, D.C.-based non-profit established in 2002 committed to restoring, enhancing and protecting the tree canopy of the nation's capital. To fulfill this mission Casey Trees plants trees, engages thousands of volunteers of all ages in tree planting and care, provides year-round continuing education courses, monitors the city's tree canopy, develops interactive online tree tools and works with elected officials, developers, community groups to protect and care for existing trees and to encourage them to add new ones.

Because of the generosity of people like you, Casey Trees has been able to plant more than 10,000 trees across the District, educate thousands of youth and adults alike on the value of urban forests, develop cutting edge online tools and partner with professionals and elected officials to protect existing trees and add new ones. Although much has been accomplished, much more work remains. We need your continued help. We thank you for your gifts and we are privileged to put your passion for the environment and trees into action.
