We inspire people to plant, nurture, and celebrate trees.

Founded in 1972, the centennial of the first Arbor Day observance in the 19th century, the Foundation has grown to become the largest nonprofit membership organization dedicated to planting trees, with over one million members, supporters, and valued partners. The impact we make on our world is accomplished through our conservation and education programs
