Since 1924, the International Society of Arboriculture (ISA) has worked to promote the professional practice of arboriculture through research, technology and education. ISA also works to foster greater worldwide knowledge of the benefits of trees. ISA has a vast network of members and component organizations (chapters, associate organizations and professional affiliates) in more than 71 countries.
ISA’s 25,000 plus members and 35,000 plus certification holders include arborists, urban foresters, researchers, students, educators and practitioners, tree owners and those that who care for and about our tree resources. These constituents provide technical expertise and services, resources, education and care in rural areas, towns and cities around the world. Arborists and Urban Foresters are essential contributors in achieving a global goal of maintaining and growing one trillion trees by 2030.
ISA is the main recognized and accredited professional credentialing body for the arboriculture and urban forestry industry. ISA credential holders are critical to ensure the proper maintenance and care for preserved and planted trees throughout their entire life cycle.
ISA's consumer-facing website, TreesAreGood.org provides the public with educational information vetted by our network of experts about the benefits of trees and how to properly care for them. The site also provides the public a search tool to find an ISA Certified Arborist in their area.
ISA is an international organization with chapters and associate organizations all over the world. All partners can be viewed online.
