Ohio Aquatic GAP Project  

The Ohio Aquatic GAP project modeled the potential distributions of crayfish, bivalves, and fish in Ohio streams.

Ohio Aquatic GAP Project Map. The goal of the GAP Analysis Program is to keep common species common by identifying those species and habitats that are not yet adequately represented in the existing matrix of conservation lands. The Gap Analysis Program (GAP) is sponsored by the Biological Resources Discipline of the U.S. Geological Survey (USGS). The Ohio Aquatic GAP (OH-GAP) is a pilot project that is applying the GAP concept to aquatic—specifically, riverine—data. The mission of GAP is to provide regional assessments of the conservation status of native animal species and to facilitate the application of this information to land-management activities. OH-GAP accomplished this through
  • mapping aquatic habitat types
  • mapping the predicted distributions of fish, crayfish, and bivalves
  • documenting the presence of aquatic species in areas managed for conservation
  • providing GAP results to the public, planners, managers, policy makers, and researchers
  • building cooperation with multiple organizations to apply GAP results to state and regional management activities.
