Biological and Habitat Surveys

In the fieldOverview

The NCWQR conducts research and bioassessment projects on the biological communities of Lake Erie, inland lakes, streams, and wetlands. Most of these projects focus on the application of benthic (bottom-dwelling) macroinvertebrates as a tool for measuring the environmental quality of aquatic ecosystems and the use of assessment tools such as the Ohio Environmental Protection Agency’s Invertebrate Community Index. The biological staff has expertise in the identification of benthic macroinvertebrates and crustacean zooplankton (cladocerans and copepods) and is highly skilled in the design and implementation of biological surveys using a wide range of sampling techniques. We are certified by the Ohio EPA to perform stream habitat assessments using the Qualitative Habitat Evaluation Index. Results of recently completed projects appear in various research reports.
