Welcome to the Wisconsin Arborist Association's (WAA) website.  Our mission is 'Improving the understanding of trees and the practice of arboriculture'.

The WAA was founded in 1964 by a small group of individuals dedicated to improving the knowledge and quality of the profession of arboriculture. Since that time it has grown into a large organization of commercial, municipal, utility and academic arborists. These members serve Wisconsin by providing private and public arboriculture services and research. The WAA is a chapter of the International Society of Arboriculture which has representation in over 30 countries.

--Eric Petersen, WAA President

Certified Arborist Exam

There are no Certified Arborist Exams scheduled at this time. Check this site later for updates.

There are a number of study materials available through ISA to assist with exam preparation. The ISA Arborists' Certification Study Guide is available for purchase on the ISA website. It is a good overall review including bolded vocabulary words, review questions, and sample test questions listed at the end of each chapter. The Application Handbook outlines the exam process and Certified Arborist Code of Ethics. The Exam Outline provides a list of topics and knowledge areas that should be mastered prior to sitting for the exam. Both resources are available for free on the ISA website.

If you have additional questions, contact Paul Fliss, Certification Chair at (262) 613-6461, or email Paul Fliss. As always, registration for the exam is made directly with the ISA, and must be completed at least 12 working days in advance.


Please note, any WAA member who wants to be listed as a Certified Arborist for Hire on the WAA web site should complete the ISA Certified Arborist for Hire Form. Contact Ian Brown at 414-286-8233 if you have any questions.

Tree Research and Education Endowment Fund (TREE Fund)

The TREE Fund provides research grants, scholarships and educational programs to advance knowledge in the field of arboriculture and urban forestry.

Dr. Richard Hauer of the University of Wisconsin at Stevens Point was recently awarded the John Z. Duling Grant from the TREE Fund for $10,000 to support his research comprised of an assessment of municipal urban and community programs. This is a reassessment of classic work completed 20 years ago and provides a very unique opportunity for comparison. The project will be a focus of an upcoming sabbatical for Rich.

The Bob Skiera Memorial Fund began accepting donations in 2010. Wisconsin arborists and friends are raising $250,000. We are close to reaching our goal. Join with current donors and Skiera Memorial Fund Campaign Pacesetters, and help us reach our goal! Please consider designating your TREE Fund donations to the Bob Skiera Memorial Fund.

Team Wisconsin will be riding in the Tour to raise funds for research and help the WAA endow the Bob Skiera Memorial Fund. If you wish to support Team Wisconsin riders, tax deductible donations via credit card are accepted at: http://www.crowdrise.com/STdTTeamWisconsin/fundraiser/stdtteamwisconsin1 When you donate, please make sure to designate your donation to the Bob Skiera Memorial Fund.
