The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

The North American recent mammals in the United States National Museum number about 166,000 specimens, including 1,435 types. More than three-fourths of this material is in the Biological Survey collection, United States Department of Agriculture, the remainder, including the seals, sirenians, ceataceans, and all of the older, more historic specimens, is in the Museum proper. The material derived from these two sources furnishes so complete a representation of the mammals of North America that, of the 2,554 forms now recognized, only 171 are not included.
