The state of Wisconsin is fortunate to have a number of state parks, national protected areas, private and public lands set aside for wildlife management, and regenerating forests—at least 194 scientific areas have been preserved by the state. Wisconsin is in an interesting transition region between northern boreal forests heavily dominated by pine and now birch, mixed hardwood forests, and prairie. The mammal fauna is a complex overlap representing each biotic region, and a wealth of new information and detailed summary of previous research on the state's mammals is now available in Charles Long's long-awaited The Wild Mammals of Wisconsin. Long is a classically trained mammalogist and The Wild Mammals of Wisconsin is a classic “mammals of …”–type volume. The state's rich mammal fauna is documented by Long with 69 full accounts of native species and briefer accounts of 7 hypothetical or invading species. Long's extensive studies of the state's small mammal fauna, especially the shrews and rodents, are incorporated into quite thorough species accounts. Accounts include descriptions, geographic range, habitat, foods, reproduction, home range, movements, den and nest sites, geographic variation, predators, parasites, evaluations of subspecific variation, and more. Discussions include geographic variation in the region, with discussions on the appropriate subspecies names. Long provides keys to the orders, families, genera, and species. Appendices on longevity of common species, preparation of mammal study skins, photographs of skulls, and conversion of English to metric measurements will make this work appealing to educators working with younger students. There is an inclusive glossary of mammalogical terms. An index to scientific and vernacular names is provided that is complete and quite useful. Distribution maps for North America and Wisconsin are included for each species. Abbreviated accounts are provided for the species that are extirpated from the state, referring the reader back to Hartley …
