Support the TREE Fund

One of the best ways to support arboriculture and urban forestry research is through the Tree Research and Education Endowment (TREE) Fund. The TREE Fund is a 501.C3 charity offering numerous grants and scholarships in support of research, outreach programs, and education in the fields of arboriculture and urban forestry.

To actively contribute to the advancement of our industry, please visit the TREE Fund website and make an online donation. You may choose to make a contribution to the general TREE Fund, or you may choose to support a specific program, such as the Safe Arborist Techniques Fund. Visit their Donation page to learn more about the dedicated funds available.
