National 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.

"Biodiversity." As argument over environmental and conservation policy grows more heated in California and throughout the nation, the term has become a buzzword. But what does biodiversity really mean? What really threatens it? Why should we care? In Our Own Hands offers a readable, scientifically sound view of California's biological diversity and what must be done to preserve it. The book will be an invaluable resource for environmental and natural resource specialists, educators, and general readers. Local and global forces threaten California's wetlands, dunes, oak woodlands, and riparian forest habitats--all declining habitats in a rapidly urbanizing, culturally heterogeneous, and politically turbulent state. Always a bellwether, California will be a model for the rest of the United States in its scientific and political solutions to conservation problems. This book proposes the first steps toward a unified national conservation policy for the twenty-first century. "Biodiversity."

The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.

The fact that approximately one-third of the world's land mass is arid desert may be congenial for the camel and the cactus, but not for people. Nevertheless, well over half a billion people, or 15% of the world's population live in arid desert areas. If the world's population were distributed evenly over the land surface, we would expect to find about 30% of the population inhabiting arid desert areas. Does the fact that 'only' 15% of the world's population live in an arid desert environment reflect the harshness of the environment? Or is it a testimony to the adaptability and ingenuity of mankind? Do we view the glass as half-full? Or half-empty? The contributors to Desert Development: Man and Technology in Sparselands adopt the position that the cup is half-full and, in fact, could be filled much more. Indeed, many arid desert zones do thrive with life, and given appropriate technological develop ment, such areas could support even greater popUlations. While the dire Malthusian prediction that rapid world population growth exceeds the carrying capacity of existent resource systems has gained popularity (typified by the 1972 Club of Rome book, Limits to Growth), there is a growing body of serious work which rejects such pessimistic 'depletion' models, in favor of models which are mildly optimistic.
