Book excerpt: Which management strategy, intervention or nonintervention, is best for the northern elk herd of Yellowstone National Park? This question was first raised in the early part of the twentieth century and resurfaced in the 1960s, prompting controversy that continues today. In response, Congress in 1997 requested that the National Academy of Sciences study the issue. This paper examines relevant National Park Service history and policy regarding this debate. Some of the primary factors scientists think have influenced elk abundance and distribution are profiled, and inherent semantic problems are examined. The 1969 natural regulation hypothesis, which has governed Yellowstone park policy since 1967, and its associated assumptions are defined. The interrelated technical issues that are key to the natural regulation hypothesis include migration and outside land conversion, historical elk population size, range expansion, baseline conditions, population stability, Native Americans, predation and fire, and sport hunting. In his paper he also revisits an obscure 1917 scientific hypothesis-that landscape alteration outside Yellowstone influences elk abundance inside the park-and restates it in broader, more modern terms: national park size influences the need for management intervention because of alteration of natural processes outside park boundaries. Some scientists perceive that intervention in the management of national park natural resources has decreased since 1872. Thus, this paper also asks whether the need for intervention is increasing as large spatial scale natural processes are progressively impeded outside the parks. Looking at the range of park natural units as a whole, a mixture of intervention and nonintervention may be the best approach.

Available in PDF, EPUB and Kindle. Book excerpt: Wagner, one of our most distinguished wildlife biologists, is a strong critic of ecological practices in the national parks. This book provides an assessment of the ecological history of Yellowstone's northern range, since before the park existed, showing the impact of US Park Service policies on the health of the areas they oversee. He demonstrates that elk had been historically rare throughout the region and that overgrazing by elk has seriously degraded the landscape and altered the structure of the area. This is a major contribution to reconstructing the ecology of this region over the course of the past 500 years. It is also a critique of US Park Service management policies and their stewardship of the nation's most cherished natural areas. Wagner's book will generate substantial attention and debate both in the scientific and policy/management communities.
