Watsonian vice-counties

The vice-counties are based on the ancient counties of Britain, but often subdividing these boundaries to create smaller, more uniform units, and considering exclaves to be part of the vice county in which they locally lie. They provide a stable basis for recording using similarly-sized units, and, although grid-based reporting has grown in popularity, they remain a standard in the vast majority of ecological surveys, allowing data collected over long periods of time to be compared easily.

The vice-counties were introduced in Hewett Cottrell Watson who first used them in the third volume of his Cybele Britannica published in 1852. He refined the system somewhat in later volumes. The vice-counties remain unchanged by subsequent local government reorganisations, allowing historical and modern data to be more accurately compared.

Every vice-county in Britain has a name, and additionally, they are numbered from 1 to 112. Vice counties in Ireland are numbered from H1 to H40.
