Book Description
This book presents working principles for assessing the relative importance of anthropogenic emission sources that contribute to haze in U.S. national parks and wilderness areas and discusses various alternative source control methods. Haze in the Grand Canyon evaluates and recommends strategies for improving critical scientific and technical gaps in the information and databases on haze. It examines such topics as methods for determining individual source contributions, regional and seasonal factors that affect haze, strategies for improving air quality models, the interactive role of photochemical exodants, and scientific and technological considerations in choosing emission control measures.

Book Description
Grand Canyon For Sale is a carefully researched investigation of the precarious future of America’s public lands: our national parks, forests, wildlife refuges, monuments, and wildernesses. Taking the Grand Canyon as his key example, and using on-the-ground reporting as well as scientific research, Stephen Nash shows how accelerating climate change will dislocate wildlife populations and vegetation across hundreds of thousands of square miles of the national landscape. In addition, a growing political movement, well financed and occasionally violent, is fighting to break up these federal lands and return them to state, local, and private control. That scheme would foreclose the future for many wild species, which are part of our irreplaceable natural heritage, and also would devastate our national parks, forests, and other public lands. To safeguard wildlife and their habitats, it is essential to consolidate protected areas and prioritize natural systems over mining, grazing, drilling, and logging. Grand Canyon For Sale provides an excellent overview of the physical and biological challenges facing public lands. The book also exposes and shows how to combat the political activity that threatens these places in the U.S. today.

Book Description
The flagship publication of the National Parks Conservation Association, National Parks Magazine (circ. 340,000) fosters an appreciation of the natural and historic treasures found in the national parks, educates readers about the need to preserve those resources, and illustrates how member contributions drive our organization's park-protection efforts. National Parks Magazine uses images and language to convey our country's history and natural landscapes from Acadia to Zion, from Denali to the Everglades, and the 387 other park units in between.

Book Description
Our national parks are more than mere recreational destinations. They are repositories of the nation's biological diversity and contain some of the last ecosystem remnants needed as standards to set reasonable goals for sustainable development throughout the land. Nevertheless, public pressure for recreation has largely precluded adequate research and resource monitoring in national parks, and ignorance of ecosystem structure and function in parks has led to costly mistakes--such as predator control and fire suppression--that continue to threaten parks today. This volume demonstrates the value of ecological knowledge in protecting parks and shows how modest investments in knowledge of park ecosystems can pay handsome dividends. Science and Ecosystem Management in the National Parks presents twelve case studies of long-term research conducted in and around national parks that address major natural resource issues. These cases demonstrate how the use of longer time scales strongly influence our understanding of ecosystems and how interpretations of short-term patterns in nature often change when viewed in the context of long-term data sets. Most importantly, they show conclusively that scientific research significantly reduces uncertainty and improves resource management decisions. Chosen by scientists and senior park managers, the cases offer a broad range of topics, including: air quality at Grand Canyon; interaction between moose and wolf populations on Isle Royale; control of exotic species in Hawaiian parks; simulation of natural fire in the parks of the Sierra Nevada; and the impact of urban expansion on Saguaro National Monument. Because national parks are increasingly beset with conflicting views of their management, the need for knowledge of park ecosystems becomes even more critical--not only for the parks themselves, but for what they can tell us about survival in the rest of our world. This book demonstrates to policymakers and managers that decisions based on knowledge of ecosystems are more enduring and cost effective than decisions derived from uninformed consensus. It also provides scientists with models for designing research to meet threats to our most precious natural resources. "If we can learn to save the parks," observe Halvorson and Davis, "perhaps we can learn to save the world."
