DOWNLOAD EBOOKThe first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

DOWNLOAD EBOOKNational parks are different from other federal lands in the United States. Beginning in 1872 with the establishment of Yellowstone, they were largely set aside to preserve for future generations the most spectacular and inspirational features of the country, seeking the best representative examples of major ecosystems such as Yosemite, geologic forms such as the Grand Canyon, archaeological sites such as Mesa Verde, and scenes of human events such as Gettysburg. But one type of habitat--the desert--fell short of that goal in American eyes until travel writers and the Automobile Age began to change that perception. As the Park Service began to explore the better-known Mojave and Colorado deserts of southern California during the 1920s for a possible desert park, many agency leaders still carried the same negative image of arid lands shared by many Americans--that they are hostile and largely useless. But one wealthy woman--Minerva Hamilton Hoyt, from Pasadena--came forward, believing in the value of the desert, and convinced President Franklin D. Roosevelt to establish a national monument that would protect the unique and iconic Joshua trees and other desert flora and fauna. Thus was Joshua Tree National Monument officially established in 1936, with the area later expanded in 1994 when it became Joshua Tree National Park. Since 1936, the National Park Service and a growing cadre of environmentalists and recreationalists have fought to block ongoing proposals from miners, ranchers, private landowners, and real estate developers who historically have refused to accept the idea that any desert is suitable for anything other than their consumptive activities. To their dismay, Joshua Tree National Park, even with its often-conflicting land uses, is more popular today than ever, serving more than one million visitors per year who find the desert to be a place worthy of respect and preservation.

DOWNLOAD EBOOK"Among the crucial problems that confront mankind today are those associated with a degraded environment. This book examines the extent to which warfare and other military activities contribute to such degradation. The military capability to damage the environment and to cause ecological disruption has escalated, and there is no sign that the level of conflict in the world is decreasing. The military use and abuse of each of the several major global habitats -- temperate, tropical, desert, arctic, insular, and oceanic -- are evalusated separately in the light of the civil use and abuse of that habitat"--Dust jacket.

DOWNLOAD EBOOKThis report summarizes each of 68 ecological surveys conducted from 1975 through 1988 on candidate and established Research Natural Areas in the Pacific Southwest Region of the USDA Forest Service. These surveys represent an important but largely unknown contribution to the ecological literature of California. For each summary, information on location, target elements, distinctive features, physical characteristics, association types, plant diversity, and conflicting impacts is provided. Comparisons are made between similar vegetation types at different sites. Tables and appendices summarize the plant communities, target elements, rare plants, and trees occurring on all areas. Maps of all areas and photographs of most areas are included.

DOWNLOAD EBOOKThe Ecological Importance of High-Severity Fires, presents information on the current paradigm shift in the way people think about wildfire and ecosystems. While much of the current forest management in fire-adapted ecosystems, especially forests, is focused on fire prevention and suppression, little has been reported on the ecological role of fire, and nothing has been presented on the importance of high-severity fire with regards to the maintenance of native biodiversity and fire-dependent ecosystems and species. This text fills that void, providing a comprehensive reference for documenting and synthesizing fire's ecological role. - Offers the first reference written on mixed- and high-severity fires and their relevance for biodiversity - Contains a broad synthesis of the ecology of mixed- and high-severity fires covering such topics as vegetation, birds, mammals, insects, aquatics, and management actions - Explores the conservation vs. public controversy issues around megafires in a rapidly warming world
