About OCVN

The OCVN program is administered by Ohio State University Extension in cooperation with several park districts and various environmental orgnizations.


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.

What is an Ohio Certified Volunteer Naturalist?

An Ohio Certified Volunteer Naturalist is an individual with a passion for the natural world who wishes to attend training and use his or her knowledge by giving back to the community through volunteer service. The program has three components: training, volunteer service hours, and advanced education. (See below for instructions on adding your email address to the statewide email listserve to stay informed.)


As Ohio's population grows more urban, it is harder for people to make the connection to nature that ultimately allows them to value their local natural resources and thus have a reason to manage and conserve them for future generations. The Ohio Certified Volunteer Naturalist (OCVN) program is a research-based scientific training program that emphasizes hands on natural resource education coupled with community-based volunteer service. The program embraces conservation but is not an advocacy group.

The Ohio Certified Volunteer Naturalist Program is based upon the very successful OSU Extension Master Gardener Program and Volunteer Natural Resource programs in other states such as Florida, Missouri, and the City of Fort Collins, CO.

*OCVN is affiliated with the Alliance of Natural Resource Outreach and Service Programs (ANROSP). Formerly the National Master Naturalist Initiative.


The formal training program is the responsibility of the OCVN coordinator or committee managing the program. Instructors are OSU faculty, ODNR professionals, Extension Specialists, Extension Associates, experienced Volunteer Naturalists, and other experts.

The training program is to provide a balanced, integrated practical course in natural resource science. The following are the core topics. Other topics based on local needs may also be part of the curriculum.
