The Ephemeroptera Recording Scheme has been set up, under the auspices of the Biological Records Centre, to encourage the recording of Ephemeroptera species throughout the British Isles. The aim of the recording scheme is to collect records of Ephemeroptera species throughout the British Isles. This will ultimately lead to the publication of an atlas of British Ephemeroptera and the monitoring of changes in the distribution of Ephemeroptera populations. Any populations that are particularly under threat will be identified and conservation advice will be provided.
