  • The STIHL Tour des Trees, an annual weeklong, 500 to 600-mile cycling adventure, is the primary public outreach and engagement event of Tree Research and Education Endowment Fund (TREE Fund). Since 1992 Tour riders have cycled to communities in the U.S., Canada and the U.K, planting trees, educating children and shining a light on the work done by arboriculture professionals and the importance of science-based tree care. The Tour serves to advance TREE Fund's mission to support scientific discovery and dissemination of new knowledge in arboriculture and urban forestry.

    Full-Tour cyclists commit to raising at least $3,500 for TREE Fund, and 100% of what they raise supports research grants, scholarships and arboriculture education programs administered by TREE Fund. TREE Fund researchers have discovered better ways to propagate, plant and care for urban trees, making them more resilient, more resistant to pests, and less prone to failure. Supported education programs connect young people with the environment and career opportunities in green industries. The legacy of the STIHL Tour des Trees includes an ever-expanding urban forest planted by its cyclists and a growing legion of civilian tree stewards in the communities along the route.

    The Tour des Trees is celebrating its 25th anniversary in 2017! Read about our history.
