In 2018, 600 people initiated Plant a Tree Day by planting over 7,000 trees at 30 locations, and the event has since expanded into a yearly global reforestation effort led by One Tree Planted.

The organization now partners with 489 groups in 84 countries and has planted more than 171 million trees.

Plant a Tree Day, held annually on September 28, encourages individuals to participate in reforestation through planting and donations, especially during the fall planting season in the Northern Hemisphere when conditions favor root growth. One Tree Planted believes that combined efforts demonstrate the impact of reforestation to communities and governments. The initiative began as a response to widespread deforestation.

A UN report found global forest area decreased by over 40 million hectares between 2015 and 2025, with a total loss of 420 million hectares since 1990. The UN also reports that while some progress has been made toward forest conservation goals, two targets, reversing forest loss and reducing poverty among forest-dependent communities, remain off track. Forests provide essential ecosystem services valued at $16.2 trillion annually and support a vast amount of biodiversity.

One Tree Planted accepts donations and recurring memberships to fund restoration projects in areas with the greatest need, and encourages local, community-organized planting events.
