The mission of the Ohio Certified Volunteer Naturalist (OCVN) program is to promote awareness and citizen stewardship of Ohio's natural resources through science-based education and community service.


OCVN Training is offered in ODD Years in Medina County.  



The Ohio Certified Volunteer Naturalist (OCVN) program is a research-based scientific training program that emphasizes hands-on natural resource education coupled with volunteer service. Participants in the OCVN program receive at least 40 hours of combined classroom and field instruction. Upon completing the instructional hours, the participants select a nature-themed organization to volunteer for, such as a nature center or the Medina County Park District, to provide 40 hours of volunteer service the first year, 20 hours in each subsequent year.  Only after you train AND volunteer 40 hours are you fully certified as a Ohio CERTIFIED Volunteer Naturalist.  You must be 18 years or older to participate.

Education programs and volunteer training coordination are provided through local chapters. There are currently 13 OCVN chapters around Ohio.
