Habitat Assessment

Habitat assessments utilized by our staff include but are not limited to the EPA Rapid Bioassessment Protocol (RBP) and Hydrogeomorphic assessments (HGM). To determine bank stability, we routinely use the Bank Erosion Hazard Index (BEHI) and Pfankuch surveys. These habitat assessment protocols are typically utilized in preparation of mitigation credit calculations and the subsequent permitting for a project, as well as for permit compliance monitoring purposes.

 
  • Rapid Bioassessment Protocol for use in streams and wadeable rivers. Used to characterize the existence and severity of impairments to the water source. This is also used to help identify sources and causes of impairment.

  • The Hydrogeomorphic (HGM/LHGM) approach employs indicators of community structure and process, aggregated into simple logic models, to indirectly reflect functionality.

  • Ohio’s Qualitative Habitat Evaluation Index (QHEI) is a method for evaluating stream habitat quality.

  • Stream Visual Assessment Protocol (SVAP) is used to evaluate the condition of aquatic ecosystems associated with streams.

  • Interim Functional Assessment Approach (IFFA) was developed by the USACE in order to assess streams and watersheds.

  • Developed and used as a stream reach inventory and channel stability evaluation.

  • The Wolman Pebble Count method is the most efficient technique to measure the characterization of substrate and bank materials.
