This overview presents the information on national breeding bird atlases in European countries as obtained in initial stage of EBBA2 project. National atlases are included only, with exception of countries where atlases have been traditionally organised at regional level. On the other hand, some atlases can include more countries (e.g. UK and Ireland). The overview has been updated according to information available to EBBA2 coordination team and will be updated regularly. We will appreciate any additions or corrections.
