Welcome to the Atlas of Mammals in Ireland website. This is an exciting new initiative which presents species accounts and distribution maps of the wild mammals that occur in Ireland and its territorial waters. The initiative pulls together data from existing recording initiatives and datasets to provide an overview of the current and historic distribution of Irish mammals. One of the primary aims of the initiative is to encourage recording of the commoner Irish mammals, so that a comprehensive picture of their distribution is achieved by 2015. This will then provide a baseline against which future changes to distribution can be tracked.
