Ecological Dynamics on Yellowstone's Northern Range discusses the complex management challenges in Yellowstone National Park. Controversy over the National Park Service's approach of "natural regulation" has heightened in recent years because of changes in vegetation and other ecosystem components in Yellowstone's northern range. Natural regulation minimizes human impacts, including management intervention by the National Park Service, on the park ecosystem. Many have attributed these changes to increased size of elk and other ungulate herds. This report examines the evidence that increased ungulate populations are responsible for the changes in vegetation and that the changes represent a major and serious change in the Yellowstone ecosystem. According to the authors, any human intervention to protect species such as the aspen and those that depend on them should be prudently localized rather than ecosystem-wide. An ecosystem-wide approach, such as reducing ungulate populations, could be more disruptive. The report concludes that although dramatic ecological change does not appear to be imminent, approaches to dealing with potential human-caused changes in the ecosystem, including those related to climate change, should be considered now. The need for research and public education is also compelling.

Schullery's book details the ecological history of Yellowstone National Park.

In 2006, one of the hottest years on record, a “pizzly” was discovered near the top of the world. Half polar bear, half grizzly, this never-before-seen animal might be dismissed as a fluke of nature. Anthony Barnosky instead sees it as a harbinger of things to come. In Heatstroke, the renowned paleoecologist shows how global warming is fundamentally changing the natural world and its creatures. While melting ice may have helped produce the pizzly, climate change is more likely to wipe out species than to create them. Plants and animals that have followed the same rhythms for millennia are suddenly being confronted with a world they’re unprepared for—and adaptation usually isn’t an option. This is not the first time climate change has dramatically transformed Earth. Barnosky draws connections between the coming centuries and the end of the last ice age, when mass extinctions swept the planet. The differences now are that climate change is faster and hotter than past changes, and for the first time humanity is driving it. Which means this time we can work to stop it. No one knows exactly what nature will come to look like in this new age of global warming. But Heatstroke gives us a haunting portrait of what we stand to lose and the vitality of what can be saved.

With detailed data from nine sites around the world, the authors examine how the so-called ‘fragmentation’ of these fragile landscapes occurs and the consequences of this break-up for ecosystems and the people who depend on them. ‘Rangelands’ make up a quarter of the world’s landscape, and here, the case is developed that while fragmentation arises from different natural, social and economic conditions worldwide, it creates similar outcomes for human and natural systems.

The fascinating story of a trial that opened a window onto the century-long battle to control nature in the national parks. When twenty-five-year-old Harry Walker was killed by a bear in Yellowstone Park in 1972, the civil trial prompted by his death became a proxy for bigger questions about American wilderness management that had been boiling for a century. At immediate issue was whether the Park Service should have done more to keep bears away from humans, but what was revealed as the trial unfolded was just how fruitless our efforts to regulate nature in the parks had always been. The proceedings drew to the witness stand some of the most important figures in twentieth century wilderness management, including the eminent zoologist A. Starker Leopold, who had produced a landmark conservationist document in the 1950s, and all-American twin researchers John and Frank Craighead, who ran groundbreaking bear studies at Yellowstone. Their testimony would help decide whether the government owed the Walker family restitution for Harry's death, but it would also illuminate decades of patchwork efforts to preserve an idea of nature that had never existed in the first place. In this remarkable excavation of American environmental history, nature writer and former park ranger Jordan Fisher Smith uses Harry Walker's story to tell the larger narrative of the futile, sometimes fatal, attempts to remake wilderness in the name of preserving it. Tracing a course from the founding of the national parks through the tangled twentieth-century growth of the conservationist movement, Smith gives the lie to the portrayal of national parks as Edenic wonderlands unspoiled until the arrival of Europeans, and shows how virtually every attempt to manage nature in the parks has only created cascading effects that require even more management. Moving across time and between Yellowstone, Yosemite, and Glacier national parks, Engineering Eden shows how efforts at wilderness management have always been undone by one fundamental problem--that the idea of what is "wild" dissolves as soon as we begin to examine it, leaving us with little framework to say what wilderness should look like and which human interventions are acceptable in trying to preserve it. In the tradition of John McPhee's The Control of Nature and Alan Burdick's Out of Eden, Jordan Fisher Smith has produced a powerful work of popular science and environmental history, grappling with critical issues that we have even now yet to resolve.

As the twenty-first century dawns, public land policy is entering a new era. This timely book examines the historical, scientific, political, legal, and institutional developments that are changing management priorities and policies—developments that compel us to view the public lands as an integrated ecological entity and a key biodiversity stronghold. Once the background is set, each chapter opens with a specific natural resource controversy, ranging from the Pacific Northwest’s spotted owl imbroglio to the struggle over southern Utah’s Colorado Plateau country. Robert Keiter uses these case histories to analyze the ideas, forces, and institutions that are both fomenting and retarding change. Although Congress has the final say in how the public domain is managed, the public land agencies, federal courts, and western communities are each playing important roles in the transformation to an ecological management regime. At the same time, a newly emergent and homegrown collaborative process movement has given the public land constituencies a greater role in administering these lands. Arguing that we must integrate the new imperatives of ecosystem science with our devolutionary political tendencies, Keiter outlines a coherent new approach to natural resources policy.
