It's more than just planting trees.
Since 1972, the Arbor Day Foundation has been hard at work helping as many people as possible not just plant trees, but truly understand their value. As we've grown to become the largest member nonprofit organization, so has our passion for getting our hands in the dirt and determination to teach everyone about the role trees play in the health of our planet. We've worked with members, supporters, and partners to plant millions of trees worldwide. But we're far from done.
The benefits of trees are truly mind-blowing. They help slow climate change, foster biodiversity, support underserved communities, protect our homes, clean our air and water, improve our mental and physical well-being, curb soil erosion, build economic opportunities, and so much more. What it comes down to is that now more than ever, the world needs more trees. We are answering the call with our ever-growing network of planting partners in keeping pace with the increasing need and focusing on areas where trees will do the most good.
Our Roots Run Deep
We're proud of our milestones and continue to lead the way in the industry.

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.
