These metrics were excluded because the total number of taxa has the most information. Among the metrics from the composition category, % ETO was retained while the other three metrics (% Aquatic insect, % Odonata, % Intolerant) were omitted because ETO (Ephemeroptera, Trichoptera, and Odonata) were sensitive species to anthropogenic pressures. BP for the diversity and evenness metrics was retained because the other three metrics were highly correlated with the total number of taxa (r > 0.75, p < 0.01)
