In 2008, Ohio Department of Natural Resource’s Division of Wildlife (ODNR) reformed the Ohio Aquatic Invasive Species Committee (OAISC) to address aquatic invasive species (AIS) in Ohio. The OAISC is made up of members representing government agency, industry, university, and non-profit stakeholder organizations and serves an informal advisory function. The group is chaired by John Navarro, ODNR and Eugene Braig, SENR.

Mission
To provide a forum for Ohio’s diverse resource-management agencies, industries, organizations, and communities to advise the state about the prevention and control of aquatic invasive species and for the state to inform those parties about developing issues and policy.
Vision
Benefit Ohioans in enhancing the conservation and sustaining the value of Ohio’s natural resources by informing effective policies and practices and by engaging stakeholders in preventing the introduction and spread of aquatic invasive species.
