We Need Forests.

They Need Us, Too.

Since 1990, the founding of our reforestation program, the Arbor Day Foundation has planted more than 180 million trees in natural forest areas across the globe. We believe that trees are an important part of the solution to many of our world's problems --- and that reforestation is one of the simplest and most critical things we can do to save our planet.

Join us as we embark on a journey to plant a better future.

Forests' Countless Benefits

Home to 1.6 billion people and 80% of all plant and animal species, our world's forests are the cornerstone of life itself.

They provide us with countless benefits --- some of which you might not even realize.

Cleaner water and air

Forests help improve water quality in streams, rivers, and lakes, as well as filter pollutants out of the air.

Carbon sequestration

Trees are one of our greatest weapons in the fight against climate change. In the United States, national forests alone absorb more than 50 million metric tons of carbon each year.

Climate regulation

Forests increase rainfall, prevent drought, and cool the overall temperature of the planet.

Habitat for wildlife

Animal species of all kinds rely on forests for food, shelter, and water.

Food security

Fruit and nut trees are an important food source for millions of people across the globe.

Recreation and wellness

From camping to fishing to hiking, forests provide us with opportunities to connect with nature and one another.

An Urgent Need

Despite all the good forests bring to our lives, these precious natural resources are in trouble.

The world has lost an estimated 1 billion acres of forest since 1990. This staggering rate can be attributed to a number of factors:


Human activity is one of the greatest contributors to forest loss. Around the globe, trees are cut down for agriculture, cattle ranching, development, and logging. Deforestation has had the most significant impact in tropical rain forests, which are at risk of disappearing completely in 100 years.


Diseases like sudden oak death, spruce decline, and white pine blister can cause significant decline in previously healthy forests.


Infestations by insects like the mountain pine beetle have reached epidemic levels in select forests, killing hundreds of thousands of trees and making the area more susceptible to fire.


Wildfires are a natural part of many ecosystems, helping promote vegetation growth by clearing away dead material. However, with climate change creating hotter and drier conditions, these fires are growing in intensity.


High winds and severe storms, including ice storms, can snap trees like toothpicks.

Our Reforestation Work

The Arbor Day Foundation helps plant trees all over the world, from the mountains of Colorado to the jungles of South America.

We have committed to planting 500 million new trees worldwide by July 2027.

Planting Partners

Our reforestation work is made possible by our network of hundreds of planting partners, including the U.S. Forest Service and Bureau of Land Management. Their expertise and intimate knowledge of local ecosystems helps guide every step of the planting process.

  • Planters pose for a picture in the Willamette River Basin, one of Oregon's largest watersheds. Nearly 400,000 trees have been planted in the area.
  • A planter prepares a seedling in Paradise, California. The area's forests were devastated after the 2018 Camp Fire, which burned more than 150,000 acres of land.
  • Say cheese! A volunteer holds a seedling near Virginia's Rappahannock River. The watershed is being replanted with more than 30,000 trees to reduce pollution levels and prevent erosion.
  • Planters get to work along Oregon's Columbia River Basin. The river is home to pacific salmon, a species in serious decline.
  • Our partners go to great heights to get the job done. This mountainside is located in Montana's Lolo National Forest, which was burned by the Sunrise Fire in 2017.

Over the past 10 years, Green Forests Work has partnered with the Arbor Day Foundation to restore forests in areas impacted by coal mining. Our strong partnership has resulted in the planting of over one million trees, as well as the creation of much-needed jobs and new economic opportunities, in the Appalachian Mountain region. We hope to continue revitalizing this beautiful area for years to come.
