This publication is the result of a collaboration between the Environmental Education Council of Ohio (EECO) and the Office of Environmental Education at the Ohio Environmental Protection Agency (OEPA). This directory of environmental education resources within the state of Ohio is intended to assist educators in finding information that can complement local curricula and programs. The directory is divided into three sections. Section I contains information on local environmental education sites and resources. These are grouped by EECO region, alphabetized by county, and further alphabetized by organization name. Resources range from arboretums to zoos. Section II lists resources available at a statewide level. These include state and federal government agencies, environmental education organizations and programs, and resource persons. Section III contains cross-referenced lists of Section I by organization name, audience, organization type, and programs and services to help educators identify local resources. Guidelines for educators to getting the most out of available but scarce resources and guidelines for resource professionals to achieving the greatest possible impact are included. (PVD)
