Percentage of EPT Individuals Minus Hydropsychid Individuals
Taxonomic counts aggregated at the order level classification in a wide data format. Use the wide function to prepare the data.
Taxonomic counts aggregated at the family level classification in a wide data format. Use the wide function to prepare the data.
The percentage of individuals identified as ephemeropterans (Order: Ephemeroptera), plecopterans (Order: Plecoptera), and trichopterans (Order: Trichoptera) (EPT) minus the percentage of hydropsychids (Family: Hydropsychidae). This family is typically tolerant and can be hyperdominant, resulting in elevated percentages of EPT that may not accurately describe the degradation gradient of interest. This metric will typically decrease with degradation.
