Call To Action: Updating The Leopold Report For National Parks in the 21st Century
Fifty years ago, human-influenced climate change was not seen as the threat to national parks that it poses today, urban pressures were not threatening to choke as many park units as they are today, and far fewer than 281 million visitors were traveling to the parks each year.
Indeed, when A. Starker Leopold and his colleagues reviewed wildlife management practices across the National Park System in 1963, they cited obvious problems, such as too many elk in Yellowstone and Grand Teton national parks. They noted the lack of science needed to drive management decisions, and they pointed out the obvious, that "habitat is not a fixed or stable entity that can be set aside and preserved behind a fence, like a cliff dwelling or a petrified tree."
But many of the issues and challenges confronting the National Park System today are different from those of the 1960s. So greatly have the factors influencing wildlife in the national parks changed over the past five decades that, in Park Service Director Jon Jarvis's mind, it's time to revisit the Leopold Report and update it for national parks in the 21st century.
For its day, the Leopold Report presented to Interior Secretary Stewart Udall clearly laid out the Park Service's role in wildlife management.
Animals within the parks should not be allowed to overpopulate the parks and degrade their habitat; culling, and even hunting, should be utilized to control populations; and there was a need for a "greatly expanded research program, oriented to management needs..." within the park system.
To that end, Leopold and his colleagues addressed three broad questions:
1) What should be the goals of wildlife management in the national parks?
2) What general policies of management are best adapted to achieve the pre-determined goals?
3) What are some of the methods suitable for on-the-ground implementation of policies?
Some came to say some of the report's recommendations were overly romantic and idyllic, particularly as presented in the following passage:
"We would recommend that the biotic associations within each park be maintained, or where necessary recreated, as nearly as possible in the condition that prevailed when the area was first visited by the white man. A national park should represent a vignette of primitive America. (emphasis added)"
To their credit, the authors of the Leopold Report recognized how grandiose their vision might sound and realized there were limitations as to how far management could recover wildlife settings.
Restoring the primitive scene is not done easily nor can it be done completely. Some species are extinct. Given time, an eastern hardwood forest can be regrown to maturity but the chestnut will be missing and so will the roar of pigeon wings. The colorful drapanid finches are not to be heard again in the lowland forests of Hawaii, nor will the jack-hammer of the ivory-bill ring in southern swamps. The wolf and grizzly bear cannot readily be reintroduced into ranching communities, and the factor of human use of the parks is subject only to regulation, not elimination. Exotic plants, animals, and diseases are here to stay. All these limitations we fully realize. Yet, if the goal cannot be fully achieved it can be approached. A reasonable illusion of primitive America could be recreated, using the utmost in skill, judgment, and ecologic sensitivity. This in our opinion should be the objective of every national park and monument.
While that report long has served the Park Service in its approach to wildlife management, Director Jarvis, in his recent Call To Action, raised the need of updating the report to current management challenges.
“The Leopold Report really was the seminal work, the foundation upon which we built our entire approach to the preservation and management, at least of the natural resources world," Mr. Jarvis told the Traveler during a recent interview. "Obviously, it’s 50 years old and it's time to revisit it."
While much of the Leopold Report remains relevant today, the director said, areas such as climate change and other human influences on the landscape -- how, for instance, the Park Service addresses vegetation, the arrival of non-native plants and species -- were not addressed by the Leopold team.
Some climate-change influences are greatly pressing on wildlife populations. Wolverines, which are dependent on snowfields, could be squeezed out of places such as Glacier National Park and North Cascades National Park as their snowfields vanish. Native fisheries -- both fresh water and salt water -- could be devastated by waters warmed by hotter summers. Vegetative changes across Alaska that result from a warming climate could pose problems for caribou.
The list goes on and on, touching on charismatic megafauna such as grizzly bears as well as birds.
Away from climate change, the lack of apex predators in parks such as Rocky Mountain, Wind Cave, Theodore Roosevelt, Valley Forge, and Gettysburg have pushed park managers to turn to hunting, culling, and even birth control in efforts to tamp down elk and deer populations.
To examine these and other 21st century influences on park wildlife and recommend revisions to the Leopold Report, Director Jarvis has assembled a distinguished team of outside experts:

The Park Service liaison to the team is Dr. Gary Machlis, the science advisor to Director Jarvis.
"They are working under the umbrella of the National Park System Science Advisory Board, so it is essentially advice to me, and the secretary of Interior, about the future of management of our national parks in light of these challenges," the director said.
With the growing challenges facing wildlife in the National Park System, their recommendations will be timely.
