While attention is often paid to community members' motivations, comparatively less attention is given to the skilled professionals who engage or donate to arboriculture and urban forestry committees, chapters, and organizations. Focusing on Canadian and American arborists and urban foresters, we used an online survey which received 1,048 responses. In asking about the perceived benefits of volunteering and donating to organizations, the most frequently identified benefit was the ability to contribute to the future of the industry (n = 616), followed by good public relations for one's company or institution (n = 513) and the ability to influence research and educational endeavors in arboriculture and urban forestry (n = 496). Job position, industry sector, educational level, and other professional demographics were often significantly associated with the selection of these benefits. We coded qualitative responses about respondents' perceptions of volunteering and donating time to industry and found three major themes: (1) Constraints to involvement or donations, frequently influenced by limited funds or available time, lack of awareness of opportunities, insurance challenges, or exclusive/unwelcoming environments. (2) Characteristics of worthwhile organizations and programs, including transparency, local and community-oriented, meaningful and unique events, environmentally and socially beneficial, and opportunities to develop skills. (3) Hesitancies to donate to research-funding organizations, based largely on lack of research dissemination and applicable research. These findings provide helpful guidance for organizations seeking to engage skilled professionals in the many opportunities for volunteerism or donations within industry.},\n  pages = {128112},\n  journal = {Urban Forestry \\& Urban Greening},\n  author = {Martin, Alexander J.

\n Volunteers comprise an important part of arboriculture and urban forestry organizations. While attention is often paid to community members' motivations, comparatively less attention is given to the skilled professionals who engage or donate to arboriculture and urban forestry committees, chapters, and organizations. Focusing on Canadian and American arborists and urban foresters, we used an online survey which received 1,048 responses. In asking about the perceived benefits of volunteering and donating to organizations, the most frequently identified benefit was the ability to contribute to the future of the industry (n = 616), followed by good public relations for one's company or institution (n = 513) and the ability to influence research and educational endeavors in arboriculture and urban forestry (n = 496). Job position, industry sector, educational level, and other professional demographics were often significantly associated with the selection of these benefits. We coded qualitative responses about respondents' perceptions of volunteering and donating time to industry and found three major themes: (1) Constraints to involvement or donations, frequently influenced by limited funds or available time, lack of awareness of opportunities, insurance challenges, or exclusive/unwelcoming environments. (2) Characteristics of worthwhile organizations and programs, including transparency, local and community-oriented, meaningful and unique events, environmentally and socially beneficial, and opportunities to develop skills. (3) Hesitancies to donate to research-funding organizations, based largely on lack of research dissemination and applicable research. These findings provide helpful guidance for organizations seeking to engage skilled professionals in the many opportunities for volunteerism or donations within industry.\n
