The Tree Research and Education Endowment Fund (TREE Fund) was established by the International Society of Arboriculture and Tree Care Industry Association in 2002, to fund programs that support the discovery and dissemination of new knowledge in arboriculture and urban forestry. The TREE Fund continued to adapt to the effects of the enduring pandemic in 2021. Highlights of the year 2021 include:
The virtual TREE Fund
The pandemic experience revealed that the TREE Fund staff works very well in a virtual environment, so to continue mitigating health risks and to dramatically reduce the indirect costs of grants and scholarships, the TREE Fund headquarters moved "to the cloud" in 2021. The main telephone number remains the same: 630-369-8300. There, you will find a menu of options for reaching individual staff members or leaving a message. The mailing address is now: TREE Fund 1755 Park Street, Suite 200, Naperville, IL 60563
The TREE Fund provided $609,146 in support of four new and 14 continuing grants and four new and four continuing scholarships during 2021.

The TREE Fund launched the new Tree and Soil Research Grant in 2021. The grant is made possible by a permanently restricted endowment fund supporting areas of research of interest to the landscape architecture community with special focus in the area of trees and the soils that support them.
During 2021, TREE Fund-supported research appeared in 11 peer-reviewed publications and was orally presented nine times. This brings the publication total for the past 18 years to 235. 
TREE Press, the TREE Fund’s newsletter, was published 12 times in 2021. The newsletter provides timely information, as well as regular features on volunteers, donors, webinars, the Tour des Trees, grants, and results from TREE Fund studies. 
The TREE Fund’s free webinars, offering certified arborists CEUs, continued to grow in significance. In 2021, the TREE Fund offered eight webinars and they were enjoyed by 7,424 participants.
• "Growing Trees in Paved Sites," Alessio Fini, PhD, University of Milan
• "Digging into the Science of Tree Planting and Removing Packaging Materials," Richard Hauer, PhD, University of Wisconsin – Stevens Point; Andrew Koeser, PhD, University of Florida; and Jason Miesbauer, PhD, The Morton Arboretum
• "Long term effects of the electrical rights-of-way vegetation management on floral and faunal communities," Carolyn Mahan, PhD, Penn State Altoona
• "A Three Pronged Approach to understanding defensive mechanisms in Green Ash resistant to EAB," Jeanne Romero-Severson, PhD, University of Notre Dame
• "Why do some trees transplant better than others? A look at some new research on water uptake,"  Nina Bassuk, PhD, Cornell University
• "LiDAR based urban tree inventory permits a better evaluation of tree services: an example from Montréal Canada," Dan Kneeshaw, PhD, University of Quebec, Montreal
• "Planning for the Next Three Letter Urban Tree Canopy Changer: Lessons Learned with DED, EAB, ETC." Richard Hauer, PhD, University of Wisconsin-Stevens Point
• "Loading a Tie-in Point While Climbing," Brian Kane, PhD, University of Massachusetts-Amherst
Tour des Trees
The TREE Fund’s signature event, the Tour des Trees, rebounded from the pandemic-induced one-year hiatus with a beautiful ride through the Rocky Mountains in Colorado. Thirty-eight riders rode their bikes over 320 miles and traversed approximately 23,500 feet of climbing over five days, starting in Denver and circling around to Boulder, Estes Park, Fort Collins, and back to Boulder and Denver. An additional 34 virtual participants also joined in from their own homes, all helping to support the TREE Fund's mission.
Strategic Plan 2021-2024
Our analysis of how to sustain the TREE Fund into the future revealed that our greatest strengths are our dedicated staff, our reputation for applicable research, and our endowed grants. Our primary goal is to strengthen our capacity to cover the full cost of our programs, respond to the emerging economy, and build for a sustainable future. When the TREE Fund can cover its full costs and maintain a reserve for crises, it will be a healthy, resilient nonprofit business on which we can depend for decades to come. Over the coming years, the TREE Fund will build on the traditional generosity of the tree care industry by reaching out to donors who love trees but are not yet part of the TREE Fund family. 
In memoriam
Tragedy befell the TREE Fund in 2021 when Will Nutter, chair of the TREE Fund Board of Trustees, perished in a motorcycle accident. In memory of Will, his remarkable character, and his exceptional leadership, the Nutter family and Wright Service Corp. established at the TREE Fund the Will Nutter Memorial Scholarship Fund in support of education. 
TREE Fund After Hours
The virtual TREE Fund After Hours event was held during the ISA Conference in December. The event featured a panel of three researchers--Drs. Richard Hauer, Brian Kane, and Bryant Scharenbroch--who all have been awarded TREE Fund grants, discussing the impact of their research and the emerging challenges and opportunities facing the arboriculture industry.
For the third consecutive year, the TREE Fund reached GuideStar's highest level of achievement for nonprofit transparency--the platinum award. GuideStar is the world's largest and most authoritative source of information on nonprofit organizations. Major donors tend to look to GuideStar as the “seal of approval” before making donations.
