Regional Coverage

Please note that these maps are generated from a database of nearly 1 million records, and so you may have to wait a little time for the results, depending on demands on the website server.

Select species and region:

The regions used here are Watsonian vice-counties, subdivisions used in biological recording based on the historic counties of Britain. These remain unchanged by subsequent local government reorganisations, allowing historical and modern data to be more accurately compared.
