It’s more than just planting.

Founded in 1972, the Arbor Day Foundation is the world’s largest member nonprofit dedicated to planting trees. Our strength is in network – a diverse group of individuals, municipalities, corporations, and planting organizations that enable us to plant trees around the world. We intentionally collaborate with partners who are deeply engaged in the areas they serve to plant the right trees in the right places to have the greatest impact.

For more than 50 years, we’ve helped plant more than 500 million trees in neighborhoods and forests across more than 50 countries. And we’re just getting started.

500 Million Trees and Counting

Now more than ever, the world needs the powerful benefits of trees to safeguard the health of our climate, our communities, and the biodiversity of the planet. We are answering the call by pursuing our next ambitious goal: planting 500 million more trees by 2027, with a focus on forests and neighborhoods of greatest need.

About Arbor Day

Known as the tree planter’s holiday, Arbor Day is a day for people to come together in recognition of the wonders of trees. Communities, schools, businesses, and individuals alike join together to plant commemorative trees, hand out free trees, provide education on tree planting and care, and celebrate all the benefits trees provide.

National Arbor Day is always celebrated on the last Friday in April, but many states observe Arbor Day on different dates throughout the year based on best tree planting times in their area. This celebration of trees, however, is not limited to the U.S. Countries around the world celebrate Arbor Day or a similar holiday dedicated to trees.
