Native Freshwater Species Surveys Across Wales (1978 to 2019)
The purpose of this data capture was to primarily monitor the distribution of freshwater invertebrates. The data comprises primarily of the Welsh abstract of freshwater invertebrates. It comes from BIOSYS, the national ecology database for freshwater species and is related to the aquatic stages of the invertebrates. Most data have been collected from main rivers as part of an extensive routine monitoring network. The data are restricted to a selection of families which contain one species only. The records cover the whole of Wales. Sites are recorded at a minimum precision of 100m. The distribution of records is biased towards main rivers and areas with historical water quality issues. This is especially true of older records. The sampling methodologies and taxa identified are the same at all sites. NB This data set has been expanded to include all freshwater data from 1978 to 2019 at all taxonomic levels. Includes river & lake macroinvertabrates, river & lake diatoms and river macrophytes.

This data was collected by ecologists. Most of the data originate from kick samples taken in main rivers and have been collected and analysed using standard sampling methodologies. The data was extracted for Wales from the Environment Wiski Kieco and does not include older records held in paper copy only. Records for families, genera and species from chosen single species families have been extracted and are reported at the species level. NB This data set has been expanded to include all freshwater data from 1978 to 2019 at all taxonomic levels. Includes river & lake macroinvertabrates, river & lake diatoms and river macrophytes
