Butterfly Atlas 2021
The Butterfly Atlas 2021 is an exciting five-year survey of Ireland’s butterflies to produce detailed distribution maps of each species and to track populations through a series of standardised transect walks from across the country. This pages shows progress with the submission of casual butterfly sightings submitted to the Data Centre since the start of 2017. If you live in or visit a part of the country where there are gaps in coverage, we would particularly welcome your butterfly sightings. Butterfly Atlas 2021 is a collaborative project between the National Biodiversity Data Centre, Butterfly Conservation Ireland, Butterfly Conservation Northern Ireland and the Centre for Data and Environmental Recording (CEDaR).
