Dataset Details - A national macroinvertebrate dataset collected for the biomonitoring of Ireland’s river network, 2007–2018 (EPA)
The data described here were originally collected for one purpose – to assess rivers nationwide to determine the quality of the macroinvertebrate communities across the country as part of the WFD ecological status assessment. These assessments indicate changes that pollution brings about in the benthic macroinvertebrate communities, i.e. larval insects (e.g. mayflies, stoneflies, caddisflies, beetles, etc.) together with crustaceans (e.g. shrimps), snails and bivalves, worms, and leeches. These changes reflect the varying sensitivities of the different groups of macroinvertebrates to the stresses caused by pollution, with sensitive species being progressively replaced by more tolerant forms as pollution increases.

Assessment of river biological quality
Please see open access publication Feeley et al. (2020) for full details. https://www.nature.com/articles/s41597-020-00618-8
Republic of Ireland
River macroinvertebrates are collected from June to September each year, 2007 to 2018, when flows are likely to be relatively low.
All data has undergone full quality control checking. Note taxonomic resolution may vary. More information is available in our open access publication Feeley et al. (2020). https://www.nature.com/articles/s41597-020-00618-8
The dataset is complete and inclusive of data collected 2007 to 2018.
