The Vertebrates of Lancashire

This is the first systematic survey to be published dealing with the distribution of animals other than birds in Lancashire and North Merseyside. Freshwater fish have been dealt with differently to other taxa is tetrad mapping was not felt to be appropriate. Instead their distribution is described within the species accounts. Some 45,000 records of mammals, and almost 20,000 records for amphibians and reptiles were used for the mapping presented here.
