Metric / Explanation of Metric
Taxa Richness / Measures the overall variety of the macroinvertebrate assemblages
EPT Index / Number of taxa in the insect orders Ephemeroptera (mayflies), Plecoptera (stoneflies), and Trichoptera (caddisflies)
% Contribution of Dominant Taxon
NCBI / North Carolina Biotic Index based mainly on Hilsenhoff Biotic Index scores that Use tolerance values to weight abundance in an estimate of overall pollution. Originally designed to organic pollution
% Shredders / Percent of the macrobenthos that "shreds" leaf litter
% EPT / Percent of the composite of mayfly, stonefly, and caddisfly larvae based on number of individuals
%CA / Percent of midge larvae
Ratio of EPT to Chironomidae / Percent of the composite of mayfly, stonefly, and caddisfly larvae to midge larvae
Cricotopus&Chironomus: Chironomidae / Compares abundance of sensitive organisms to abundance of tolerant organisms.
Hydropsychidae/Trichoptera / Relative abundance of pollution tolerant caddisflies
SC/FC / Ratio of specialist to generalist feeding strategies
Indicator Assemblage Index (IAI) / Compares mayfly, stonefly, and caddisfly larvae to midge larvae and annelids relative to a reference site (change in abundance of sensitive organisms to change in abundance of tolerant organisms
Shannon-Weiner Diversity (log10) / Diversity index incorporating richness and evenness
Total Habitat Score / Composite of scores based on riparian zone, bank, channel, and substrate conditions.
Ratio or EPT taxa to all macroinvertebrate taxa / Compares the number of taxa in the insect orders Ephemeroptera (mayflies), Plecoptera (stoneflies), and Trichoptera (caddisflies) relative to the influence of overall macroinvertebrate taxa richness
