Based on over 115,000 sighting records of British mammals, collected by amateur naturalists and professional zoologists between 1969 and 1991, this major atlas summarises all the data to form the most accurate picture available to date of the distribution of mammals in Britain (including the Channel and Scilly Isles, but excluding N Ireland and Eire). Every recorded species is described, with a table of basic record details and a distribution map. A total of 65 species is listed. There are also tables of records from individual islands, brief records of vagrant species, and details of exotic escapes.
