caseytrees

We are a Washington D.C.-based nonprofit, established in 2001, committed to restoring, enhancing and protecting the tree canopy of the nation’s capital.

To fulfill this mission, we plant trees, engage thousands of volunteers of all ages in tree planting and care, provide year-round continuing education courses, monitor the city’s tree canopy, develop interactive online tree tools and work with elected officials, developers, and community groups to protect and care for existing trees and to encourage the addition of new ones.
