The Leopold Report is a 1963 paper composed of a series of ecosystem management recommendations that were presented by the Special Advisory Board on Wildlife Management to United States Secretary of the Interior Stewart Udall. Named for its chairman and principal author, zoologist and conservationist A. Starker Leopold,
the report proved influential for future preservation mandates and
reports. After several years of public controversy regarding the forced
reduction of the elk population in Yellowstone National Park, Udall appointed an advisory board to collect scientific data to inform future wildlife management
of the national parks. The committee observed that culling programs at
other national parks had been ineffective, and recommended management
of Yellowstone’s elk population. In addressing the goals, policies, and
methods of managing wildlife in the parks, the report suggested that in
addition to protection, wildlife populations should be managed and
regulated to prevent habitat degradation. Touching upon predator
control, fire ecology, and other issues, the report suggested that the National Park Service
hire scientists to manage the parks using current scientific research.
The Leopold Report became the first concrete plan to manage park
visitors and ecosystems under unified principles. It was reprinted in
several national publications, and many of its recommendations were
incorporated into the official policies of the NPS. Although the report
is notable for proposing that park management have a fundamental goal
