Benthic Macroinvertebrate Bioassessment Studies

ECORP ecologists conduct benthic macroinvertebrate (BMI) bioassessments relative to potential habitat impact assessment and community structure impairment resulting from altered stream flows and sediment deposition (e.g., downstream releases from dams, diversions, and hydroelectric power facilities). Our aquatic invertebrate laboratories are located in Rocklin and Santa Ana to provide statewide services. We are approved by California Department of Fish Game (CDFG) to perform California Stream Bioassessment Procedure (CSBP) protocols and Surface Water Ambient Monitoring Program (SWAMP). Our staff are members of the Southern California Association Marine Invertebrate Taxonomists (SCAMIT).

Services Provided

• Sample processing and identification, metrics calculation and analysis
• Compliance with CSBP and SWAMP protocols
• Natural Resource Damage Assessment (NRDA), including liaison with federal/state Trustees
• Taxonomy of BMI carried to CSPB Level 1 and 2
• Estuarine and marine benthic ecology and taxonomy
• Routine in-house and CDFG audits for taxonomic verification
• Rapid bioassessment monitoring for pre- and post-construction activities
• Bioassessment monitoring pursuant to California State and Regional Water Quality Control Board clean up and abatement orders
