Become a TreeKeeper & Help Protect the Urban Forest
The TreeKeepers certification course, which Openlands began in 1991, has trained over 2,000 volunteers to conserve, protect, and advocate for the region’s urban forest. To become certified as a TreeKeeper, participants must complete the course requirements listed below and pledge to volunteer after graduation. Once certified, TreeKeepers can host volunteer workdays, attend advanced trainings, and work in a local chapter to advance community forestry goals.
Becoming a TreeKeeper can be an entry way to:
- Understand the environmental community in the Chicago region
- Learn how trees can help mitigate the impacts of climate change
- Meet and connect with many of the organizations doing “green” work
- Join a respected and frequently requested group of educated volunteers
- A new career
The Openlands TreeKeepers certification course takes place three times a year in Chicago as well as in the suburbs. One of the three courses each year is offered in Spanish.
