University of Illinois Extension's Illinois Master Naturalist Program is designed for adults of any age that want to learn about and positively impact their local environment. The goal of the program is not to teach you everything there is to know about the subjects being covered, but to give you an engaging exposure to the natural world--one that encourages you to seek lifelong learning opportunities to further your development as a naturalist.
Master Naturalist Program participants have the opportunity to:
- learn about Central Illinois' natural history, ecosystems, plant and animal communities, and environmental issues
- enhance your love of nature through hands-on training and community-based service
- practice lifelong learning and sharing
- interact and build relationships with new acquaintances with similar interests
- give something back to nature and your local community
- and learn from and work side-by-side with experts
Master Naturalists must complete 60 hours of field, classroom, and digital learning and 60 hours volunteer service within two years to become a Certified Master Naturalist. To remain active in the program, an additional 30 hours volunteer service and 10 hours of continuing education must be performed yearly.
Adult learners can also take the same educational training, which we refer to as Natural Resources Core Education class, for professional and personal development only. This is the non-volunteer option.
Upcoming Master Naturalist Training
Master Naturalist Core Education Training is the first step to becoming an Extension Master Naturalist. The next training is scheduled for September 28 - October 2, 2026.
