Our Mission

In support of Kansas State Research and Extension we shall be an educational, non-profit, volunteer organization dedicated to fulfilling the state program’s mission to develop a corps of well-informed volunteers to provide education, outreach, and service dedicated to the beneficial management of natural resources and natural areas within their communities for the State of Kansas. 

Who We Are

The Extension Master Naturalist (EMN) program is sponsored by K-State Research and Extension to provide the community with unbiased, research-based information and expertise on protecting and maintaining the natural resources of Kansas.  We accomplish this through the efforts of volunteer Extension Master Naturalists (EMN’s).

All EMN’s share a passion and love of nature.  They come from all walks of life and varying backgrounds, are trained and certified by the EMN organization in Kansas natural resource concepts and share their training and passion through a variety of EMN activities including restoration of natural areas, wildlife monitoring, citizen science and public awareness. In 2019 EMNs donated over 6850 hours of service worth more than $144,500  and directly impacted over  8700 people.

For more information on EMN activities see What We Do.
