Tree Stewards of Arlington and Alexandria (TSAA) are trained volunteers who care for urban trees on public and private property and teach others through educational programs, tree plantings, and tree maintenance. You do not need to be a resident of Arlington or Alexandria to be a member. All are welcome to apply for our training program, although the Fall 2026 application deadline has passed. Volunteer work may be performed in DC, Maryland, or Virginia.

Once you complete the training program, you will be expected to participate in volunteer events or perform other volunteer service. Examples of volunteer opportunities include (but are not limited to):
● Planting, pruning, mulching, and watering street and park trees;
● Advising private property owners on tree selection;
● Staffing informational booths at farmers’ markets and local festivals;
● Leading neighborhood tree walks or speaking at community gatherings;
● Removing invasive vines and plants that threaten trees;
● Supporting administrative tasks such as writing blog articles and maintaining data and other records.

Each Tree Steward trainee makes a commitment to perform 20 volunteer hours (30 during your first-year’s internship) in local Tree Steward projects and 8 hours of continuing education annually.

When the training application period opens for classes in subsequent years, we will announce it here and on local media.
