Other UK Atlases
Hertfordshire is not the only county in the UK to be running or have already completed a tetrad-based atlas of the birds of its region. Since the first national atlas organised by the BTO between 1968 and 1972 many hours of fieldwork have gone into producing other atlases. Only a few have an online presence, but those that do have been collected here.
The links on the right provide access to those that we know about. If, as an atlas organiser or fieldworker in another part of the country, you are aware of a local atlas website that we are missing, please let us know by email.
