WAA on Facebook

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.

--Ron Gumz, WAA President

WAA 2015 Summer Conference ‘Back to Basics with Practical Application: Part 1’ and WAA Tree Climbing Championship

Back after a year’s hiatus because of the ISA Conference in Milwaukee, the WAA presents the Summer Conference on August 14th in Madison at the UW Arboretum. Three different Tracks of Education will be offered including Plant Health Care, Tree Basics, and Safety Matters. Several different walk and talk presentations will be held throughout the day so everyone will have a chance to enjoy the grounds while learning too. PJ Liesch will talk about insect plant health care, Brian Hudelson will show you tree diseases and fungi identification, Laura Jull will do some plant id, and Mike Wendt will demonstrate structural pruning on young trees. Chipper and chain saw use and safety will be highlighted in Track Three throughout the day. Finally, please bring in your arboricultural questions and samples to “Ask the Experts”.

Only a short drive away from the Arboretum, WAA’s Tree Climbing Championship will be held Saturday, August 15th at Goodman Park in Madison. Please come and cheer on our Wisconsin climbers! For more information about TCC, check our web page at http://www.waa-isa.org/tree_climbing.htm. So mark your calendars for August 14th and 15th. We look forward to seeing you at the Arboretum and at Goodman Park!

Parking: There will be limited parking available. Please try to carpool!

See our Summer Conference Brochure for complete details.

Secure on-line registration is now closed. Walk-ups will be welcome, however, the late fee will be in effect.

Certified Arborist Exam

Two Certification Exams have recently been scheduled. The first Certification Exam will be held in conjunction with the WAA Summer Conference on Friday, August 14, 2015, in Madison, WI. The second exam will be held in conjunction with the WAA Fall Seminar on Thursday, October 15, 2015 in Hales Corners, WI. Please check the ISA website listed below for more information and for registration under Professional Credentials/ Exam Dates and Locations.

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.

Last year, Dr. Richard Hauer of the University of Wisconsin at Stevens Point was awarded the John Z. Duling Grant from the TREE Fund for $10,000 and matched by WAA to support his research comparing municipal urban and community programs 20 years after the last assessment. Rich is now on sabbatical working on this project.

The Bob Skiera Memorial Fund was established with a lead gift of $75,000 from the Wisconsin Arborist Association and began accepting donations in 2010. Wisconsin arborists and friends committed to raising $250,000 and we reached this goal just before the 2014 ISA conference in Milwaukee! Thanks to everyone for your generosity and hard work. Now, join with current donors and Skiera Memorial Fund Campaign Pacesetters, and help us reach out to new donors around the state, the nation and the world to fully endow the fund at $500,000!! Please consider designating your TREE Fund donations to the Bob Skiera Memorial Fund and encourage others to do the same.

Team Wisconsin members Doug Drysdale, Dick Rideout, Andy Schoofs and Troy Schreiner will be riding in the 2015 STIHL Tour des Trees in Florida this October to continue to help WAA raise funds for its Chapter Challenge and 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.
