Although the American bison was saved from near-extinction in the nineteenth century, today almost all herds are managed like livestock. The Yellowstone area is the only place in the United States where wild bison have been present since before the first Euro-Americans arrived. But these bison pose risks to property and people when they roam outside the park, including the possibility that they can spread the abortion-inducing disease brucellosis to cattle. Yet measures to constrain the population threaten their status as wild animals. Mary Ann Franke’s To Save the Wild Bison is the first book to examine the ecological and political aspects of the bison controversy and how it reflects changing attitudes toward wildlife. The debate has evoked strong emotions from all sides, including park officials, environmentalists, livestock growers, and American Indians. In describing political compromises among competing positions, Franke does not so much champion a cause as critique the process by which federal and state officials have made and carried out bison management policies. She shows that science, however valuable a tool, cannot by itself resolve what is ultimately a choice among conflicting values. The only truly wild bison left in the U.S. are in Yellowstone National Park. Yellowstone's bison descend from fewer than 100 animals, the last free-roaming bison in the country, and are untainted by crossbreeding with cattle. From the early 1900s to the 1960s, the bison were managed by culling the herds, but from then on the idea of natural control has taken hold and bison numbers have grown. At some point early in the last century, bison were infected with the cattle disease brucellosis, which causes spontaneous abortion. The stage was now set for the conflict--Yellowstone's growing bison herd, members of which sometimes leave the park in winter to find food, versus Montana, Wyoming, and Idaho's cattle industries, which don't want possibly infected bison to come into contact with their cattle. Franke, a nine-year employee of Yellowstone, writes an in-depth history of the bison controversy, covering both the ecological and political aspects and all sides of the question.
