Arborists and Urban Foresters' Engagement with Non-profit Organizations

Alexander Martin, University of Toronto

Lukas Olson, University of British Columbia


Many environmental non-profits or NGOs rely on arborists and urban foresters to support their programming through donating money, providing technical support, or sitting on boards and committees. To better understand what drives or dissuades urban greening professionals from supporting NGOs, we conducted an online survey of Canadian and American arborists and urban foresters. With the help of organizations like TREE Fund, we distributed the survey through listservs, social media groups, and magazines, receiving 1,047 responses.


The perceived benefits of volunteering and donating varied. Arborists and urban foresters volunteer and donate to help the future of their industries, improve or maintain positive public relations for their company or institution, and influence industry research and education. These benefits far outweighed financial incentives like tax benefits. 


The economy and work hours can limit both donations and volunteering. While some individuals wished to contribute their time or resources, they often faced constraints because of their own busy schedules and/or limited incomes. Others felt NGOs were inadequate advertising opportunities for their companies or that insurance requirements restricted their involvement.


Arborists and urban foresters actively and preferentially participate in local community events that are environmentally or socially beneficial. This is especially true when the program is distinctive and allows them to enhance their own skills. Those donating looked for organizations that are transparent about their finances and objectives and were critical of research-funding organizations that lacked research dissemination or applicable research.

TREE Fund Liaison Spotlight


Every ISA chapter recruits a volunteer to serve as their TREE Fund Liaison. These volunteers spend extra time attending meetings, spreading the word about TREE Fund happenings, events, and news, and often being the point person for TREE Fund fundraisers at their local chapters.


We'd like to highlight these wonderful volunteers and let you know a little more about them.


Pacific Northwest Chapter Liaison: Peter van Oss

Senior Associate, Teragan & Associates, Inc.

18 years as a TREE Fund Liaison.


Q: Why do you enjoy being an arborist?

A: It’s more like a hobby and I never really go to work.


Q: Why did you choose to be the liaison for your chapter?

A: Being involved with peers in the industry and to spread the word to our future potential arborists.


Q: Why do you feel the need to communicate TREE Fund’s mission and events to chapter members?

A: Our industry is one of the youngest professions and we have only scratched the surface when it comes to understanding how people can live with trees. Trees are incredibly important in our microclimates and advanced research will allow us to implement cutting edge technology to ensure conservancy and proper planning for our future generations.


Q: What would you like to learn more about in your field or what research would you like to see done?  

A: How much soil can be removed from a root soil plate before the tree becomes unstable. 


Q: Why is new research important to you?

A:  Advancing our knowledge of trees may allow for us to get a better understanding of how we can properly plan for a sustainable future.
