Conservation Biology Trailblazers: George Wright, Ben Thompson, and Joseph Dixon

Abstract: Modern conservation biologists may reap great insight from neglected documents prepared by field biologists of the past. Three U.S. National Park Service field biologists of the 1920s and 1930s, George Wright, Ben Thompson, and Joseph Dixon, collaborated on the first field faunal survey of U.S. national parks. The results, Fauna 1 and Fauna 2 , were published in 1933 and 1935, respectively. In addition to information about the status of park vertebrates, these monographs produced the first comprehensive list of ecologically based policies for the U.S. National Park System. They also contained precursors of many of the ideas now considered basic to conservation biology. Today's conservation biologists seem unaware of the work of these three researchers. Contemporary biologists tend to think of the key concepts in conservation biology as having developed after the 1970s, but Wright, Thompson, and Dixon expressed in rough form many of these concepts half a century before. They combined their ideas with those of their predecessors and mentors to produce an
