American Buffalo in Transition

Between 1800 to 1890 the free roaming buffalo in North America were reduced from an estimated 60 million to fewer than 20 wild bison in the U.S. " Now there are over 17,000 bison living under varying degrees of supervision ranging from private herds to restrictive zoos to large parks where the animals can again roam freely. This book is an attempt to present a survey of the decimation of the bison; to consider the major factors that have influenced the growth of the buffalo population since 1990." From the book's preface.
