ISA 2025 Annual Report Now Live

Mar 13, 2026 Categories: March 2026

Each year, the International Society of Arboriculture (ISA) publishes a report to highlight the organization’s accomplishments, financial status, and data from various departments. The Annual Report ultimately provides an overview of the past year for ISA’s stakeholders. 

The 2025 Annual Report is now available on the ISA website. Click here to review the report in full. 

Please note that the current 2025 Annual Report includes only unaudited financial statements. Once the financial statements have been audited, the report will be updated to reflect the audited statements. 

 

Image Database

ISA has a vast inventory of arboriculture- and urban forestry-related images that were compiled with the help of our members and volunteers.

Through a partnership with Forestry Images, ISA has thousands of photos and graphics available for use. ISA either owns the photos or has permission to permit their use.
