Today • IDEM sampling • Assessment exercise
MACROINVERTEBRATE COMMUNITYMONITORING EXAMPLE INDIANA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT
STAGES OF BIOLOGICAL COMMUNITY ASSESSMENT • DATA REDUCTION AND ANALYSIS • SAMPLE COLLECTION • FIELD PROCESSING • LABORATORY PROCESSING
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.”
STAGES OF A BIOLOGICAL COMMUNITY ASSESSMENT • DATA REDUCTION AND ANALYSIS • SAMPLECOLLECTION • FIELD PROCESSING • LABORATORY PROCESSING
Aquatic Larvae Aquatic Adults Terrestrial Adults
USEPA Rapid Bioassessment Protocols Riffle Habitats
STAGES OF A BIOLOGICAL COMMUNITY ASSESSMENT • DATA REDUCTION AND ANALYSIS • SAMPLE COLLECTION • FIELD PROCESSING • LABORATORY PROCESSING

100 Organism Sub-Sample Selected at Random Final Sort Under Microscope Second Sub-Sample 15 Minutes Entire Pan “Randomly” Sorted Using Forceps
STAGES OF A BIOLOGICAL COMMUNITY ASSESSMENT • DATA REDUCTION AND ANALYSIS • SAMPLE COLLECTION • FIELD PROCESSING • LABORATORY PROCESSING
LABORATORY BENCHSHEET SITE INFORMATION TAXONOMIC INFORMATION AND TAXA COUNTS TEN SUB-METRICS
Example of 2 Sub-Metrics E EPT Index = 6 Families P Metric Scores = 0, 2, 4, 6, 8 EPT Count = 7 Individuals T
Multi-Plate Samples are Collected Individually Multi-Plate Samples are Preserved in the Field and Scraped in the Laboratory
SUMMARY Systematic Community Assessments of Benthic Macroinvertebrate Communities are Effective
IBI -- Family Level Multi-Metric Indices Provide: • Cost Effective Data of Ecological Health of Rivers and Streams • Assessment Information to Make Management Decisions
