Becoming an Extension Master Naturalist

If you have a love of nature, want to improve your skills and knowledge of Kansas natural resources and like to work with people, the EMN program may be for you.  EMN's are trained and certified in Kansas Natural Resource concepts. They, in turn, give voluntary service in a variety of ways that utilize their training. 

EMN’s provide information to the public based on research-based information, and provide educational program assistance in support of county extension and other educational programs. Extension Master Naturalist volunteers may not participate in the Extension Master Naturalist Program for personal gain or for commercial recommendations or endorsements.  

Who Can Apply? 

Any resident of Johnson County, Kansas, or the greater Kansas City metro area, age 18 or over, with a high school diploma or equivalent, who has an interest in natural resources can apply. 

What is next?

Once accepted, EMN’s participate in 40 hours of classroom and hands-on instruction in natural resource concepts.  Classes in the training include:

  • Botany
  • Entomology
  • Ecology
  • Mammals
  • Forestry
  • Ornithology
  • Interpretation
  • Geology
  • Bats and Herpetology

Training for 2022 will be offered March 9 through May 18, 2022.

How much does it cost?

There is a fee of $120 which covers the cost of training materials and instruction.

What Happens After Training is Completed?

Following basic training, EMNs continue their education with 10 hours of advanced training annually. In exchange for training, individuals are required to return a minimum of 30 hours a year of volunteer service on environmental activities that benefit the community.

Why Volunteer?

  • Increase your knowledge about Kansas natural resources
  • Make new and interesting friends
  • Serve the community in new and exciting ways
  • Experience new things in nature and science
  • Share your passion for nature with others
