Reflecting a new generation of conservation biologists' upper-division and graduate level conservation biology courses, as well as for individual reference, this book incorporates a number of new authors and additional chapters, covering all aspects of one of the most dynamic areas in the life sciences. Containing ten additional chapters, it includes such timely topics as ecosystem management and the economics of conservation.

Refecting what a new generation of conservation biologists is doing and thinking, this vital and far ranging second edition explores where conservation biology is heading. It challenges many conventions of conservation biology by exposing certain weaknesses of widely accepted principles. Combining contributions from both the school and the new breed of conservation biologists, this insightful text focuses primarily on topics the are integral to the daily activities of conservation biologists. Several chapters address ecosystem restoration and biotic invasions as well as the the mechanics of population viability analyses, which are now a routine facet of conservation efforts. A case history approach is implemented throughout the book, with the use of practical real-world examples. Furthermore, an in-depth look at quantitative analyses is presented, allowing for models and mathematical analyses to pinpoint limitations in existing data and guide research toward those aspects of biology that are most likely to be critical to the dynamics of a species or an ecosystem.

One of California's most remarkable wetlands, Suisun Marsh is the largest tidal marsh on the West Coast and a major feature of the San Francisco Estuary. This productive and unique habitat supports endemic species, is a nursery for native fishes, and is a vital link for migratory waterfowl. The 6,000-year-old marsh has been affected by human activity, and humans will continue to have significant impacts on the marsh as the sea level rises and cultural values shift in the century ahead. This study includes in-depth information about the ecological and human history of Suisun Marsh, its abiotic and biotic characteristics, agents of ecological change, and alternative futures facing this ecosystem.

The UC Natural Reserve System, established in 1965 to support field research, teaching, and public service in natural environments, has become a prototype of conservation and land stewardship looked to by natural resource managers throughout the world. From its modest beginnings of seven sites, the UC NRS has grown to encompass more than 750,000 wildland acres. This book tells the story of how a few forward-thinking UC faculty, who’d had their research plots and teaching spots destroyed by development and habitat degradation, devised a way to save representative examples of many of California’s major ecosystems. Working together with conservation-minded donors and landowners, with state and federal agencies, and with land trusts and private conservation organizations, they founded what would become the world’s largest university-administered natural reserve system—a legacy of lasting significance and utility.This lavishly illustrated volume, which includes images by famed photographers Ansel Adams and Galen Rowell, describes the natural and human histories of the system’s many reserves. Located throughout California, these wildland habitats range from coastal tide pools to inland deserts, from lush wetlands to ancient forests, and from vernal pools to oak savannas. By supporting teaching, research, and public service within such protected landscapes, the UC NRS contributes to the understanding and wise stewardship of the Earth.

• • • John Harper • • • Nature conservation has changed from an idealistic philosophy to a serious technology. Ecology, the science that underpins the technol­ ogy of conservation, is still too immature to provide all the wisdom that it must. It is arguable that the desire to conserve nature will in itself force the discipline of ecology to identify fundamental prob­ lems in its scientific goals and methods. In return, ecologists may be able to offer some insights that make conservation more practicable (Harper 1987). The idea that nature (species or communities) is worth preserv­ ing rests on several fundamental arguments, particularly the argu­ ment of nostalgia and the argument of human benefit and need. Nostalgia, of course, is a powerful emotion. With some notable ex­ ceptions, there is usually a feeling of dismay at a change in the sta­ tus quo, whether it be the loss of a place in the country for walking or rambling, the loss of a painting or architectural monument, or that one will never again have the chance to see a particular species of bird or plant.
