Let’s transform our love into action by planting trees!

Plant Trees for Mother's Day

Together, reforesting the globe.

Thanks to supporters like you, we successfully supported habitat restoration for the Monarch Butterfly! While Mother's Day has passed, our mission continues.

You can support global reforestation any day of the year.

We're on a Mission to Reforest the Globe

Global Reforestation

We work with local planting partners in more than eighty countries, across diverse ecosystems, to fund large-scale, high-impact projects.

Established Non-Profit

One Tree Planted is a 501(c)(3) non-profit environmental charity that makes it simple for individuals, businesses, and foundations to make an impact around the world.

Positive Impact

Every One Tree Planted project is done in partnership with local communities and environmental organizations. Together, we can restore forests, create habitat for biodiversity, and make a lasting social impact.

Project Highlight

Monarch High Forest Restoration

This project focuses on two types of restoration: converting deforested farmland back to native forest, and reforesting areas that have been severely degraded by clear-cutting, forest fires, and bark beetle infestation. By planting oyamel and other native tree species to restore montane oyamel fir and pine forests, we can help restore critical nesting grounds for the eastern migratory monarch, improve water filtration and watershed health, protect vital ecosystem services for nearby communities, and more.

The Monarch Butterfly Journey

Every year, in the late spring and early summer months, when nature is reawakening after a long winter, something magical happens. From the Rocky Mountains to the Atlantic Ocean, and from southern Illinois to Canada, the air is abuzz with emergent eastern migratory monarch butterflies. 3-5 generations of monarchs are laid and hatched at these summer breeding grounds, each living for just a few weeks. This is their journey.

The Journey Begins

From the Rocky Mountains to southern Illinois and northward to Canada, the summer breeding grounds for eastern migratory monarchs are expansive. By late summer, the last generation enters a time of reproductive diapause, suspending mating behaviors and reaching a state of physiological dormancy. Unlike previous generations, who have a lifespan of just a few weeks, these monarchs will live up to 9 months. Seasonal changes signal the beginning of a massive migration to their overwintering grounds in Mexico.

Winter Comes

As summer fades into autumn and early winter, the monarchs' arrival in Mexico coincides with La Dia de los Muertos — and many believe they carry the spirits of the departed. After an epic journey navigating mountains, rivers, deserts, and plains, and traveling up to 120 miles a day, the butterflies arrive at oyamel fir forests in central Mexico. Here, they hunker down for the winter. Oyamel fir trees provide monarchs with just the right amount of shelter and protection they need to survive the colder months.

Spring Has Sprung

As early spring announces itself with melting snow and budding flowers, eastern migratory monarchs know it's time to mate and begin their journey north. Once they reach Texas, the last generation of butterflies from the previous year’s journey lay their eggs and die. These eggs will be the beginning of a new generation of monarchs. Instinctually, these new butterflies know they must continue traveling north, to reach summer breeding grounds they have never seen.

The cycle continues

Once the first generation of monarchs reaches their summer breeding grounds, they lay their eggs and pass the torch to their offspring. Thus, the stage is set for another year of survival, migration, and renewal for this incredible species.
