Mayfly (Ephemeroptera) Data for Great Britain for 1906-2017
Mayfly records compiled largely from country agency samples of river invertebrates together with research data from CEH, information from consultancy operations and casual records from amateur recorders. The Ephemeroptera Recording Scheme intends to produce an atlas of the data in due course.
The data is mainly focussed on running waters and gives good coverage of England, Scotland and Wales. There is some patchy coverage in Southern England and Scotland.
Primarily water quality sampling, taxonomic interest, conservation policy and consultancy.
Third party and amateur data supplied by others was validated by the Scheme organiser. Identification would have been carried out by freshwater specialists in data supplied by country agencies.
The majority of records were collected by standard sampling by Environment Agency and SEPA staff. Other records will have been made from casual observations or local surveys.
