The primary focus of the Division of Wildlife's Stream Conservation Program is protection and restoration of stream habitats to benefit native species. The focus of these efforts will be Species of Greatest Conservation Need (SGCN). Trends in abundance and distribution of these species will be quantified through development and implementation of an assessment program.  All species listed as SGCN are native to Ohio. These species have been drawn from Ohio and federal lists of threatened and endangered species and from species having NatureServe rankings of Vulnerable, Imperiled, or Critically Imperiled for Ohio.
