Master Naturalists

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.

This flyer is a handy resource to use to invite others to become a Master Naturalist.


Naturalist Core Education Training is the first step to becoming an Extension Master Naturalist. The next training is scheduled for June 10-14, 2024.

About Our Program

Why Become a Master Naturalist?

Nature is everywhere, in your neighborhood, in your backyard, and in your house. Becoming more educated about the natural world increases your awareness and appreciation of it, enriching your everyday life. In the tradition of John Muir, John James Audubon, and even Teddy Roosevelt, as a naturalist you can contribute to conservation and a greener world. And you can play an important role in sharing that world with others in your community.

What Qualifications Must I Meet?

Anyone can become a Master Naturalist - it does not require a degree or years of experience. You do, however, need to:

  • Have a sincere desire to learn and share natural resource information within your community
  • Be able to communicate effectively
  • Be willing to devote time to volunteering and continuing education

What Does the Training Involve?

Training sessions are typically offered one day a week over a three-month period and are led by expert educators in the region. Approximately 60 hours of classroom instruction and field study and 60 hours of volunteer internship work are required to complete the program and become certified. In order to remain a certified Master Naturalist, 30 hours of volunteer work and 10 hours of continuing education or advanced training are required each year.
