one tree planted
for every hiker
MammothMarch cares deeply about our planet's future.
In addition to creating low- to zero-waste events, we want to give back to nature. That's why we're planting one tree for every registered hiker to support reforestation projects!
Trees clean our air and water, create habitats for biodiversity, contribute to our health and wellbeing, and create jobs for social impact.
We can't think of a better partner than OneTreePlanted, a 501(c)(3) nonprofit dedicated to global reforestation by planting trees to restore nature & biodiversity.
Together, we want to raise awareness about the importance of trees, offer businesses and events like ours a simple sustainability solution, and motivate younger generations to do something positive for the environment.
Help us make sure that each step taken is one closer to a healthier planet!
Our 2024 donation
Just like last year, we are supporting a new MammothMarch state with our 2024 donation: Texas!
The project – including the planting of our 21,600 mainly longleaf pines – will concentrate efforts to restore, enhance, and conserve longleaf pine ecosystems within the Longleaf Ridge and Big Thicket Significant Geographic Areas (SGA), spanning over 117,000 acres within the southern Angelina and Sabine National Forests.
These geographic areas represent the western extent of longleaf pine’s historic range and will benefit all native wildlife species within these SGAs, in particular several key species of interest: The area is home to the federally endangered red-cockaded woodpecker, the last known populations in Texas of the Louisiana pine, the Bachman’s sparrow, and a host of additional unique species.
This project is expected to have direct and positive benefits for all species, because each depends upon the longleaf pine habitats that this project will restore and/or enhance.
Thank you to all 21,600 registered MammothMarch participants in 2024!
Our 2023 donation
... went to a 2023 new MammothMarch state: Oregon suffered from wildfires back in September 2020, where the Archie Creek, Holiday Farm, Beachie Creek, and Riverside fires burned 100,000+ acres. We supported a restoration project with the planting of 14,735 seedlings, part of a multi-year effort to rehabilitate those Bureau of Land Management lands to improve water quality and support wildlife, fisheries, wilderness, botany, recreation, and late successional ecosystems in these regions.
Our 2022 donation
We have planted a total of 5,441 trees (one for every registered hiker) in the Farmington Forested Wetland Restoration project in western Trumbull County, Ohio! Restored forested communities were seeded with a native herbaceous seed mix and planted with a diverse assemblage of native trees and shrubs.
