Arbor Day

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

Founded in 1972 — the centennial of the first Arbor Day observance — the Arbor Day Foundation is the largest 501(c)3 nonprofit membership organization dedicated to planting trees. More than 1 million members, supporters, and valued partners have helped us plant more than 350 million trees in neighborhoods, communities, cities, and forests throughout the world to ensure a greener and healthier future for everyone.

Our vision is to help others understand and use trees as a solution to many of the global issues we face today, including air quality, water quality, a changing climate, deforestation, poverty, and hunger.

The impact we make on our world is accomplished through our conservation and education programs. We work to restore forests, improve tree cover in communities, and inspire the next generation of tree planters to ensure this important work endures.
