Parks and Carrying Capacity is an important new work for faculty, graduate and undergraduate students, and researchers in outdoor recreation, park planning and management, and natural resource conservation and management, as well as for professional planners and managers involved with park and outdoor recreation related agencies and nongovernmental organizations.

The national parks of North America are great public treasures, visited by 300 million people each year. Set aside to be kept in relatively natural condition, these remarkable places of forests, rivers, mountains, and wildlife still inspire our "capacity for wonder." Today, however, the parks are threatened by increasingly difficult problems from both inside and outside their borders. This book, enriched with personal anecdotes of the author's trips throughout the parks of North America, examines changes in the park services of the United States and Canada over the past fifteen years. William Lowry describes the many challenges facing the parks—such as rising crime, tourism, and overcrowding, pollution, eroding funding for environmental research, and the contentious debate over preservation versus use—and the abilities of the agencies to deal with them. The Capacity for Wonder provides a revealing comparison of the U.S. National Park Service (NPS) and the Canadian Parks Service (CPS). The author explains that, while the services are similar in many ways, the priorities of these two agencies have changed dramatically in recent years. Lowry shows how increasing conflicts over agency goals and decreasing institutional support have make the NPS vulnerable to interagency disputes, reluctant to take any risks in its operations, and extremely responsive to political pressures. As a result, U.S. national parks are now managed mainly to serve political purposes. Lowry illustrates how in the 1980s politicians pushed the NPS to expand private uses of national parks through development, timber harvesting, grazing, and mining, while environmental groups push the NPS in the other direction. Over the same period, the CPS enjoyed a clarification of goals and increased institutional supports. As a result, the CPS has been able to decentralize its structure, empower its employees, and renew its commitment to preservation. Lowry considers several proposals to change the institutions governing the parks. His own recommendations are more in line with proposals to revitalize public agencies than with those that suggest replacing them with private enterprise, state agencies, or endowment boards. Lowry concludes that preserving nature should be the primary, explicit goal of the park services, and he calls for a stronger commitment to that goal in the United States.

National parks are one of the most important and successful institutions in global environmentalism. Since their first designation in the United States in the 1860s and 1870s they have become a global phenomenon. The development of these ecological and political systems cannot be understood as a simple reaction to mounting environmental problems, nor can it be explained by the spread of environmental sensibilities. Shifting the focus from the usual emphasis on national parks in the United States, this volume adopts an historical and transnational perspective on the global geography of protected areas and its changes over time. It focuses especially on the actors, networks, mechanisms, arenas, and institutions responsible for the global spread of the national park and the associated utilization and mobilization of asymmetrical relationships of power and knowledge, contributing to scholarly discussions of globalization and the emergence of global environmental institutions and governance.

The question of how many people is too many at a recreation site is becoming increasingly urgent as more resource use produces more problems of crowding and overuse. This book applies research to management by using hard data to solve real problems.

The global popularity of outdoor recreation and ecotourism is on the increase. At present, there is little systematic information on the management practices that have been successful in National Parks. This book presents the issue of how to manage outdoor recreation in ways that protect the integrity of park resources and the quality of the visitor experience. Using case studies drawn from the U.S. National Park System, it illustrates a range of successful management approaches that can be applied worldwide.

U.S. mariculture production of bivalve molluscs-those cultivated in the marine environment-has roughly doubled over the last 25 years. Although mariculture operations may expand the production of seafood without additional exploitation of wild populations, they still depend upon and affect natural ecosystems and ecosystem services. Every additional animal has an incremental effect arising from food extraction and waste excretion. Increasing domestic seafood production in the United States in an environmentally and socially responsible way will likely require the use of policy tools, such as best management practices (BMPs) and performance standards. BMPs represent one approach to protecting against undesirable consequences of mariculture. An alternative approach to voluntary or mandatory BMPs is the establishment of performance standards for mariculture. Variability in environmental conditions makes it difficult to develop BMPs that are sufficiently flexible and adaptable to protect ecosystem integrity across a broad range of locations and conditions. An alternative that measures performance in sustaining key indicators of ecosystem state and function may be more effective. Because BMPs address mariculture methods rather than monitoring actual ecosystem responses, they do not guarantee that detrimental ecosystem impacts will be controlled or that unacceptable impact will be avoided. Ecosystem Concepts for Sustainable Bivalve Mariculture finds that while performance standards can be applied for some broad ecosystem indicators, BMPs may be more appropriate for addressing parameters that change from site to site, such as the species being cultured, different culture methods, and various environmental conditions. This book takes an in-depth look at the environmental, social, and economic issues to present recommendations for sustainable bivalve mariculture.
