- Statement
- This data has been processed in the following manner: * Data from all EA sampling regions (Anglian, Midlands, Northeast, Northwest, Southern, Southwest and Thames) have been combined into one data file * Samples taken outside of the Spring (March-May inclusive) and Autumn (September-November inclusive) were removed * Data were restricted to three-minute kick samples only (meaning 'dredge' samples were removed) * All data taken before 2002 were removed * Only data classified in the following taxa by the EA were retained: Ephemeroptera, Plecoptera, Hemiptera, Megaloptera, Odonata, Coleoptera, Trichoptera, Turbellaria, Annelida, Crustacea, Diptera and Mollusca * Total abundance of macroinvertebrates per Sample ID were summed at the family-level within these taxa * Eleven samples with anomalous abundance counts for a taxonomic group were removed from the data * The number of sampling occurrences was calculated for each site-season-year combination, and only sites where samples had been taken in both spring and autumn at least once for a minimum of three years in the remaining time series (2002-2019) were retained. The data have been pooled by family and wider taxonomic groupings.
