The foremost experts on the North American Model of Wildlife Conservation come together to discuss its role in the rescue, recovery, and future of our wildlife resources. At the end of the nineteenth century, North America suffered a catastrophic loss of wildlife driven by unbridled resource extraction, market hunting, and unrelenting subsistence killing. This crisis led powerful political forces in the United States and Canada to collaborate in the hopes of reversing the process, not merely halting the extinctions but returning wildlife to abundance.

Conservation has run a cyclical course, Fox contends, from its origins in the 1890s when it was the province of amateurs, to its takeover by professionals with quasi-scientific notions, and back, in the 1960s to its original impetus.

First published in 1981 by Little, Brown, this book was warmly received as both a biography of Muir and a history of the American conservation movement. It is now available in this new Wisconsin paperback edition.
