Atlases of the flora and fauna of Britain and Ireland

The biodiversity of Great Britain and Ireland is one of the most well-studied geographical areas of its size in the world. This biota work has resulted in the publication of distribution atlases for many taxonomic groups. This page lists these publications.

A full atlas is generally regarded as a definitive work on distribution, whereas a provisional atlas is typically produced as an interim stage to show survey progress.

One of the bodies responsible for publishing a great number of distribution atlases is the Institute of Terrestrial Ecology. Each atlas presents 10 km² distribution maps for the species within its scope. Maps typically use different symbols to signify records from differing time-periods - solid symbols for 10-km squares (hectads) that have recent records, and unfilled symbols for 10-km squares for which only older records exist, according to a defined cut-off date.

The atlases are produced by the Biological Records Centre (BRC), which is run by the Institute of Terrestrial Ecology, part of the Centre for Ecology and Hydrology based at CEH Wallingford, Crowmarsh Gifford, Oxfordshire. The data used to produce the maps is gathered by volunteer biological recorders and collated by the BRC Recording Schemes.

The atlases fall into two groups:
