Become a Certified TreeKeeper With Openlands

Please refer to this link:


Marquette Park Field House
6743 S. Kedzie Ave., Chicago
9:30AM – 12:30PM


Since 1991, more than 1,500 trained volunteers have provided “eyes and ears on the ground” year round in neighborhoods all over Chicago to spot improper planting, vandalism, insect infestation, and other problems.

TreeKeepers learn how to help keep trees green and growing. TreeKeepers volunteer in a variety of situations from street tree care and tree planting to woodland stewardship. TreeKeepers are passionate ambassadors who help educate their neighbors as well as their public officials about the importance of trees for the greater good.

The Openlands TreeKeepers program is an 8-day course with class and field components. Lessons are taught by nationally and world-renowned experts focused on managing and reducing the threats to forest health. Some of the topics covered include tree biology, soils, tree identification, pruning, tree selection, planting and mulching, and invasive species. The College of Education at Aurora University will also offer two graduate credit hours for an additional fee.

In order to become certified, participants are required to:

Attend all 8 classes (missed classes may be made up at a subsequent series)
Pass a written exam
Complete practical exams on tree planting, mulching, and pruning
Pledge 24 volunteer hours within the year following graduation
Have fun while learning about the urban forest!
For more information and scholarship requests, please contact [masked].
