About OCVN

Welcome to the Ohio Certified Volunteer Naturalist Program

The OCVN program is a research-based education program of The Ohio State University offered in partnership with several host locations, such as, park districts and various environmental organizations. The OCVN progam emphasizes hands-on natural resource and environmental education coupled with volunteer service. Participants in the OCVN program receive 40 hours of combined classroom and field instruction. Upon completing the OCVN course, participants provide 40 hours of volunteer service at any Ohio organization with a compatible program mission.  OCVN courses are offered at several host sites. To get started, click on the Find a Course tab above. 

After course completion, OCVNs typically volunteer in the following service categories.

Education/Interpretation & Outreach
Volunteer to give an educational and/or interpretive program at a park or arboretum. Lead nature hikes, or help develop a visitor guide for a natural area! Many of these places depend on volunteers for helping educate visitors.
Citizen Science
Volunteer to collect data for a University, agency, or not for profit organization. Wildlife and plant surveys, water quality monitoring, and other scientific monitoring are some examples. These surveys are critical for maintaining and managing for biological diversity.
Land Stewardship
Volunteer to maintain a natural area, control invasive species or restore native vegetation. Or, perhaps you’d like to assist in maintaining a trail or other public recreation area. If you like to get your hands dirty, this might be your way of volunteering.
Program Support
Nature centers, local, state, and federal park visitor centers, and various natural resources groups need volunteers to work on newsletters, help with educational events, help manage meetings, websites, and even meet and greet the public at information stations. This is a great way to give back if you have physical limitations, want to hone your skills in these areas, or just want to contribute in a way that may be less physically taxing.


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