Through research, technology, and education, the International Society of Arboriculture (ISA) promotes the professional practice of arboriculture and fosters a greater worldwide awareness of the benefits of trees. This is our passion and serves as our mission statement.
ISA exists so that professionals, allied professionals, public officials, and consumers worldwide recognize the economic, environmental, and societal benefits and values of trees and their care at a cost that demonstrates the wise stewardship of resources. We are registered in the State of Illinois as a 501c (5) nonprofit organization.
The following guiding principles provide a framework for our objectives and inspire us to advance ISA’s mission and communicate our philosophy to our diverse audiences. These guiding principles steer our organization and support our vision as we advance ISA’s mission.
