    Restore Forests in the USA

    Making an Impact with One Tree Planted

    • Why We Do It

      Home to iconic biodiversity such as the brown bear, white-tailed deer, and countless songbirds, United States forests face a range of threats, including forest fires, disease, insect infestations, historic clearing, growing urban sprawl, and more. Our US projects are done in partnership with the U.S. Forest Service, state forestry agencies, conservation districts, and many other organizations, and allow us to work across several states and ecosystem types.

      One Tree Planted has planted trees in 38 US states, and our projects restore forests in the wake of major wildfires, repair damage caused by industry and resource extraction, and support endangered species, including the Southern Resident Orca of the Pacific Northwest.

    • How We Do It

      Severe threats to United States forests continue to escalate in size, frequency, and intensity. Uncharacteristic wildfires, insect infestations, diseases, drought, flooding, invasive species, and climate change endanger native forests and create a need for restoration. Severely degraded areas are vulnerable to invasive species, which, along with climate change, increases the risk of forest conversion.

      Planting trees in the right place, at the right time, with the right species, can change the current trajectory of forests in the United States. Resilient forests are one of the best natural climate change solutions, and we need more of them to face it head on. Climate-informed reforestation, including both natural regeneration and tree planting, is vital to growing more resilient forests that will help address the wildfire crisis, sequester carbon, and enhance biodiversity and ecosystem services. By planting trees today, we are able to restore historically degraded ecosystems and grow the strong, climate resilient forests of tomorrow.

      A personalized tree certificate (see gallery) to say thanks for your donation. We’ll also send you a report on the USA project that your donation was allocated to, so you can better understand your trees' impact on the environment and communities.

    • What We Plant

      Every tree we plant will impact the surrounding ecosystem, and must be selected with great care. We work with our planting partners to ensure each species we plant will only provide benefits to the surrounding ecosystem.

      Our United States projects focus on planting trees for forest fire recovery, climate change resilience, and biodiversity habitat. A typical planting might include species such as Ponderosa Pine, California Redwood, Maple, Elderberry, Willow, Birch, Dogwood, and Walnut. Species are carefully selected with a range of factors in mind, including the specific region, climate, and purpose of the planting.

    Keep Track of Your Impact

    Project Reports

    Every One Tree Planted project begins with a detailed proposal from a local planting partner, which details where, why, and how the trees will be planted. After planting wraps up, our Monitoring, Reporting and Verification Team works closely with our reforestation partners to map and monitor their growing trees. This allows us to analyze the impact the trees will have on overall forest health, biodiversity, and surrounding communities.

    We take donor impact reporting seriously, and require our reforestation partners to track and report specific metrics for every project that is completed. Click on the button below to view a planting report from a recent reforestation project.

    Why Plant Trees?

    Six Pillars of Reforestation

    Forests provide jobs to over 1.6 billion people, absorb harmful carbon from the atmosphere, and provide key ingredients for 25% of all medicines. Have you ever taken aspirin? The active ingredient in aspirin comes from the bark of a tree! At One Tree Planted we focus on the 6 Pillars of Reforestation. These pillars are the foundation of why planting trees is such a significant action to take.


    Trees help to clean the air we breathe. Through their leaves and bark, they absorb harmful pollutants and release clean oxygen for us to breathe. In urban environments and other ecosystems, trees absorb pollutant gases such as nitrogen oxide, ozone, and carbon monoxide, and sweep up particles such as dust and smoke. Increasing levels of carbon dioxide caused by deforestation and fossil fuel combustion trap heat in the atmosphere.


    Trees play a key role in capturing rainwater and reducing the risk of natural disasters such as floods and landslides. Their intricate root systems act as natural filters, removing pollutants and slowing down the water’s absorption into the soil. This process prevents harmful waterslide erosion and reduces the risk of over-saturation and flooding. According to the UN Food and Agriculture Association, a mature evergreen tree can intercept more than 15,000 litres of water every year.


    A single tree can be home to hundreds of species of insects, fungi, mosses, mammals, and plants. Depending on the type of food and shelter they need, different forest animals require different types of habitat. Without trees, forest creatures would have nowhere to call home.

    Social Impact

    From arborists to loggers and researchers, the job opportunities provided by the forestry industry are endless. We don’t just rely on trees for work, though. Sustainable tree farming provides timber to build homes and shelters, and wood to burn for cooking and heating. Food-producing trees provide fruit, nuts, berries, and leaves for consumption by both humans and animals, and pack a powerful nutritional punch.


    Did you know that hospital patients with rooms overlooking trees recover faster than those without the same view? It’s impossible to ignore that feeling of elation you get while walking through a calm, quiet forest. Trees help reduce stress and anxiety, and allow us to reconnect with nature. In addition, shade provided by canopy cover helps to protect our skin from the ever-increasing harshness of the sun.


    Trees help cool the planet by absorbing and storing harmful greenhouse gases such as carbon dioxide into their trunks, branches, and leaves — and releasing oxygen back into the atmosphere. In cities, trees can reduce ambient temperatures by up to 8° Celsius. With more than 50% of the world’s population living in cities — a number expected to increase to 66% by the year 2050 — urban trees are more important than ever.

    Case Studies

    Our Highlighted Projects

    One Tree Planted has planted trees in six global regions: North America, Latin America, Africa, Asia, Europe, and The Pacific. Every reforestation project has a unique impact on forests, communities, biodiversity, and the environment. Check out the incredible impact some of our past projects have made!

    Rim Wildfire Restoration


    Read more

    In 2013, the Rim Fire burned over 250,000 acres of grass-oak woodlands, chaparral, Ponderosa Pine, and mixed conifer forests within the course of three months. This project aimed to restore so much of what was lost by planting trees. With over 1,000 hectares restored, the goal was to return mixed conifer forests to the severely degraded landscape, protecting water quality and reestablishing habitat for native species.

    By restoring a mixed conifer mosaic to the landscape, habitat will be restored and connectivity will be increased for native species. This project was designed to create both an Old Forest and an Open Canopy mosaic, ensuring resiliency and sustained habitat for a range of key wildlife species. The trees planted in this project also helped to promote climate change resilience for generations to come, protecting local communities and ecosystems.

    Mason Riparian Restoration


    Read more

    This project helped to restore riparian habitat that had been degraded by human activities while also contributing to the Protect The Orca initiative. Riparian plantings absorb nutrients and other pollutants before they reach streams. Planting trees along rivers and streams of the Pacific Northwest restores salmonid habitat, the Orca’s main food source. Trees help reduce pollution and improve the health and quantity of salmon for the orca to eat.

    The trees planted around the rivers and streams that feed into the orca's habitat reduced water contamination, lowered toxicity, protected salmon spawning grounds, and improved the orca’s food supply. This project brought benefits to other species of wildlife, as well as the communities in the surrounding areas.

    Mined Land Restoration


    Read more

    This project focused on restoring previously mined land. Reforestation provided numerous benefits including: control of unwanted vegetation, creation of young-forest habitat in the short-term, and creation of mature forest habitat in the long-term. This project helped to restore contiguous native forest cover to a larger tract of surface-mined land that was reclaimed to a wildlife habitat.

    The area was surface mined for coal in the 1980s and heavily compacted during reclamation, seeded with primarily non-native grasses and legumes, and planted with discontinuous areas of trees. Because of the excessive soil compaction and well-established non-native vegetation on these lands, natural tree regeneration was very limited and did not occur in a reasonable timeframe without intervention. Reforestation is helping to restore these lands into a thriving ecosystem, impacting local flora and fauna for generations to come.
