Historic Records (before 2010)
NB: Species maps are derived from records held in Cofnod's database and are not necessarily a reflection of the true distribution of the species.
To contribute to this and other Atlases, please submit your records through Cofnod's
Online Recording System
To view distribution maps of a mammal species, enter part of the common or scientific name in the search box, then choose from the list of results that appears.
When the species results load, you will see
records at a low resolution.
into an area of interest, the map will automatically change to a progressively higher resolution of each record, if recorded at a high enough resolution.
squares indicate more records of that species within that grid square.
The mapping options menu on the right allows you to display
records, and lets you lock the resolution.
