This reference work presents information on the wide range of mammals that have been introduced by humans. It also provides an indication of any adverse consequences to the local fauna or flora which have resulted. The book includes details of the dates of introductions, the person or agency responsible, the source populations, the locations of release, the fate of the introductions and the impact if known, for over 300 species of mammal. Well illustrated with maps and line drawings, this reference work will enable scientists to assess future potential future introductions (or re-introductions). It also provides a valuable reference for students of ecological systems management and biological conservation.The author, based in Australia, had a lifetime of research into exotic fauna. He was the author of a companion volume, Introduced Birds of the World, published in 1981, which still remains a standard work on its subject.
