Teaming up to plant ultra-dense, biodiverse forests around the world

We're thrilled to announce that One Tree Planted is partnering with SUGi to plant 15,000 trees of 185 native species across 4,700 square meters to create 5 urban forests around the world. Together, we're restoring a degraded temperate rainforest on the coast of Cornwall in the UK and rehabilitating a cattle farm as a sanctuary for native species in Queensland, Australia. Add to that the transformation of a de facto parking lot into a community hub in suburban Chile and the creation of a dense forest to shade suburban residents from southern France's intense summer heat, plus a new community forest on the site of a former landfill in Cambridge, Massachusetts. Each of these pockets of biodiversity has been carefully selected to maximize our collective impact. 

We're just getting started and excited to see how this partnership grows over time and look forward to transforming more urban spaces together!

WHAT is the miyawaki method?

Before we dive into the project details, let's explore what the Miyawaki Method is all about — and why it's such an impactful way to plant trees. Pioneered by Japanese botanist Akira Miyawaki, the Miyawaki method is a unique way to transform public and private spaces big and small into vibrant native forests that are self-sustaining within 2-3 years.

To achieve this, native tree species are planted more densely than a typical planting so that the growing trees receive sunlight only from the top, forcing them to focus most of their energy on growing tall rather than wide. When done correctly, research has shown that Miyawaki forests can become approximately 30x denser, grow 10x faster and become virtually maintenance-free after around 3 years.

An unofficial parking lot in a a small town in the countryside, close to Santiago de Chile, this project is in a high traffic area and has been heavily degraded over time. We recently planted a SUGI forest here with 3,000 trees from 30 native species across 1,000 square meters to restore biodiversity by uniting fragmented habitat, restoring damaged soils, reducing surface temperatures, improving water filtration, and more!

The trees will also provide shade for the hundreds of people that visit every week, become an educational platform and hub for area students, and give the local community an opportunity to connect with nature.

At St. Columb Major Academy on Cornwall's Atlantic coastline, we'll be using the Miyawaki method to densely plant 1800 trees from 18 native species across 600 square meters in partnership with academy students and community volunteers who will ensure long-term stewardship of this forest.

A mini temperate rainforest, this planting will be filled with unique species of lichen, algae, moss, ferns and more! Today, there are only 1% of these special spaces left — and they're classified as one of the most endangered forest ecosystems in the world. Situated along the gulf stream, the Cornwall region's climate provides mild, damp conditions that are ideal for rainforest biodiversity to flourish.

1600 trees from 80 species have been planted across 400 square meters on a cattle farm to restore biodiversity by creating a wildlife corridor that connects our Miyawaki Forest to a native forest nearby. “Clearview” at Dingo Pocket Road is a sanctuary for many native species in tropical North Queensland, Australia. The trees planted here will encourage habitat rehabilitation, benefiting the over 50 native species that call this ecosystem home. The trees will also prevent soil erosion on degraded land and gullies and provide shade for livestock and campers enjoying the area recreationally.

Paul Joly’s Forest is an ambitious project in a suburban city south of Metz, France: 7200 trees of 24 native species planted across 2,400 square meters will bring charm & soul back to a newly built park and protect the residents from intense heat and heavy traffic nearby. They'll also boost biodiversity, reduce the harmful effects of air pollution, noise and excessive heat, bring the community together, and more!

The project was originally initiated by a group of citizens formed after the first global climate protests. Their hope is to inspire other cities nearby Metz to create similar projects in the years to come.

Danehy Park — United States

Danehy Park is a 50-acre recreational facility built on the site of the former city landfill, which was closed to active dumping in the early 1920s. The city of Cambridge, MA subsequently reclaimed what would have been a wasteland and turned it into an active community resource. Cambridge residents enjoy softball, soccer, biking, jogging and nature study at the park.

Together, we're planting 1,400 trees from 32 native tree species across 4,000 square feet to increase biodiversity, allow neighbors and visitors to experience and learn about native plants, create a sense of community inclusiveness, and more!

Plant Trees Where They're Needed Most

As the need for reforestation is global and ever-changing, we feature where trees are most needed now. Today, we're raising funds to jumpstart forest fire recovery in British Columbia. Learn more

With your help, we will:

  • Restore landscapes damaged by a historic season of wildfires
  • Create habitat for iconic biodiversity like the moose and grizzly bear
  • Support old-growth management areas to maintain complex ecosystems
  • This reforestation initiative is helping to restore the landscape in British Columbia after the Hanceville fire burned over 590,000 acres in 2017 and natural regeneration has not occurred. The fire has impacted the forest, soils, riparian ecosystems, wildlife, and water quality. Local indigenous communities have seen their ability to hunt and gather food drastically altered. But your support will go a long way! The goal of planting trees here is to not only re-establish a healthy forest, but also to plant species that will be resilient in the face of climate change. Thank you so much for your support of healthy forests! 🌲
  • Planting trees will catalyze the process of returning the area to a forested state. Newly planted trees will begin the process of sequestering atmospheric carbon, and over time improve the hydrological benefits of the forest. The ecosystems that have been greatly simplified by extreme fire conditions will once again become complex ecosystems, This project will also create habitat for many local wildlife species including mule deer, moose, black and grizzly bear, wolves, sandhill cranes, various raptors, songbirds, and small mammals.
  • A personalized tree certificate (see gallery) to say thanks for your donation. We'll also send you updates about this project, so you can track the impact your trees are having on the community and environment.
  • B.C.'s rich forest diversity includes more than 40 different species of native trees, with some of Canada’s most interesting and valuable tree species. In this project, we made efforts to maximize species diversity, including the following species: Douglas-fir, lodgepole pine, hybrid spruce, ponderosa pine, trembling aspen.
