Welcome to the Wisconsin Arborist Association (WAA)

The WAA has been dedicated to our mission "To improve the practice of arboriculture and increase public appreciation of trees and urban forests."  Over the years, this organization of commercial, municipal, utility and academic arborists has grown to include over 700 members with the like-minded goal of taking care of Wisconsin's trees.

These members service Wisconsin by providing private and public arboriculture services, research and outreach activities. The WAA is a chapter of the International Society of Arboriculture which has representation in over 30 countries.

2020 Updates to the WAA Constitution

The Board of Directors would like to utilize the next Business Meeting at the Annual Conference on February 17, 2020 to update the Constitution to reflect the current needs of the organization. According to the WAA Constitution, the membership must do this by voting to approve any modifications to the Constitution. This will be done by voice-vote at the meeting. The goal of the edits is to ensure the vitality of the organization and to confirm the association is abiding by its governing rules. There are several changes the Board of Directors would like to set forth.  The redlined words show the proposed changes.

Please review these changes prior to the Business Meeting and please attend this meeting so your voice can be heard!
