  1. Final stuff: • Lab practical: Apr 29 • Final exam: due Fri May 7 @ 2:15

  2. Today • IDEM sampling • Assessment exercise

  3. MACROINVERTEBRATE COMMUNITYMONITORING EXAMPLE INDIANA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT

  4. STAGES OF BIOLOGICAL COMMUNITY ASSESSMENT • DATA REDUCTION AND ANALYSIS • SAMPLE COLLECTION • FIELD PROCESSING • LABORATORY PROCESSING

  5. What are We Trying to Measure ??

  6. BIOLOGICAL INTEGRITY “The ability of an aquatic ecosystem to support and maintain a balanced, integrated, adaptive community of organisms having a species composition, diversity, and functional organization comparable to the best natural habitats within a region.”

  7. STAGES OF A BIOLOGICAL COMMUNITY ASSESSMENT • DATA REDUCTION AND ANALYSIS • SAMPLECOLLECTION • FIELD PROCESSING • LABORATORY PROCESSING

  8. Aquatic Larvae Aquatic Adults Terrestrial Adults

  9. Adult and Larval Caddisflies (Trichoptera)

  10. USEPA Rapid Bioassessment Protocols Riffle Habitats

  11. Two Composite KICK Screen Samples

  12. STAGES OF A BIOLOGICAL COMMUNITY ASSESSMENT • DATA REDUCTION AND ANALYSIS • SAMPLE COLLECTION • FIELD PROCESSING • LABORATORY PROCESSING

  13. Sample Elutriation • Remove Gravel and Sand • Remove Excess CPOM

  14. The Final Sample Ready for Preservation

  15. Field Preservation of Samples

  16. PAPERWORK…PAPERWORK…. TRIPLE REDUNDANCY • Water Chemistry • Habitat Assessments • Field Observations GPS for Spatial Reference

  17. STAGES OF A BIOLOGICAL COMMUNITY ASSESSMENT • DATA REDUCTION AND ANALYSIS • SAMPLE COLLECTION • FIELD PROCESSING • LABORATORY PROCESSING

  18. All Samples are Returned to Laboratory for Processing

  19. Squares (25 cm2)Removed by Suction to Petri Dish 100 Organism Sub-Sample 15 Minute Sort Sub-Sample

  20. 100 Organism Sub-Sample Selected at Random Final Sort Under Microscope Second Sub-Sample 15 Minutes Entire Pan “Randomly” Sorted Using Forceps

  21. Sub-Samples Processed to Family Level

  22. All Samples Preserved for Permanent Museum Storage

  23. STAGES OF A BIOLOGICAL COMMUNITY ASSESSMENT • DATA REDUCTION AND ANALYSIS • SAMPLE COLLECTION • FIELD PROCESSING • LABORATORY PROCESSING

  24. LABORATORY BENCHSHEET SITE INFORMATION TAXONOMIC INFORMATION AND TAXA COUNTS TEN SUB-METRICS

  25. Example of 2 Sub-Metrics E EPT Index = 6 Families P Metric Scores = 0, 2, 4, 6, 8 EPT Count = 7 Individuals T

  26. Scoring Criteria for Riffle KICK Samples

  27. Not All Rivers and Streams Have Riffle Habitats

  28. Multi-Plate Samples are Collected Individually Multi-Plate Samples are Preserved in the Field and Scraped in the Laboratory

  29. SUMMARY Systematic Community Assessments of Benthic Macroinvertebrate Communities are Effective

  30. IBI -- Family Level Multi-Metric Indices Provide: • Cost Effective Data of Ecological Health of Rivers and Streams • Assessment Information to Make Management Decisions
