Book Description
The Endangered Species Act (ESA) is a far-reaching law that has sparked intense controversies over the use of public lands, the rights of property owners, and economic versus environmental benefits. In this volume a distinguished committee focuses on the science underlying the ESA and offers recommendations for making the act more effective. The committee provides an overview of what scientists know about extinctionâ€"and what this understanding means to implementation of the ESA. Habitatâ€"its destruction, conservation, and fundamental importance to the ESAâ€"is explored in detail. The book analyzes: Concepts of speciesâ€"how the term "species" arose and how it has been interpreted for purposes of the ESA. Conflicts between species when individual species are identified for protection, including several case studies. Assessment of extinction risk and decisions under the ESAâ€"how these decisions can be made more effectively. The book concludes with a look beyond the Endangered Species Act and suggests additional means of biological conservation and ways to reduce conflicts. It will be useful to policymakers, regulators, scientists, natural-resource managers, industry and environmental organizations, and those interested in biological conservation.

Book Description
This book represents the most comprehensive compilation of data on threatened vascular plants ever published. It includes the names of some 33,000 plant species determined to be rare or threatened on a global scale. Conservation assessments were provided by the IUCN Species Survival Commission, the National Botanical Institute (South Africa), Environment Australia, and CSIRO, The Nature Conservancy, the Smithsonian Institution, and the Royal Botanic Gardens, Kew, together with hundreds of botanic gardens and botanists throughout the world. The Royal Botanic Gardens Edinburgh and the New York Botanical Garden have made major in-kind contributions.The result of 20 years work by botanists and conservationists around the world, it is intended as a conservation tool, a provider of baseline information to measure conservation progress and as a primary source of data on plant species. Most importantly, however, it provides the building blocks on which to base a worldwide effort to conserve plant species.

Book Description
During the last hlO hundred years man has changed from living in equilibrium with the natural world which sustained him, to a new position in which he is now its undisputed ruler - and very often out of equilibrium - able in a matter of hours to reduce miles of forest to devastated, potential desert. This destructive and wasteful ability has increas~d dramatically over recent years. At the same time however the need for conservation, particularly of plants as a resource for the future, has also become apparent, along with the realisation that advanced technologies can produce more from existing agricultural and forest regions. This may to some extent relieve the heavy pressure on the vulnerable areas where short term over-exploitation leads to permanent destruction of whole ecosystems, and the attendant loss, for ever, of many of the animals and plants which originally lived there. There still remains today a vast number of plant species whose potential is unknown. Maybe they will never have more than aesthetic value to mankind. But who knows where, for example, the next anti cancer agent may be found. And anyway future generations may not be ready to accept such anthropocentric values, and the options should be kept open for the philosophical concept that all life on earth has a right to exist and that man has none to exterminate.

Book Description
Proposal submitted to the Bureau of Land Management (BLM) in response to an RFP (Request for Proposal). The proposed project is to conduct field research on threatened and endangered plants in the Wells S.E. Area of Nevada, with an emphasis on, but not limited to, rare and endangered plants listed for Elko County. The survey will include the following plants, which have already been collected in the Wells Study Area: Astragalus lentiginosus Dougl var latus, Cryptantha interrupta, Eriogonum argophyllum Reveal, and Sclerocactus pubispinus. Collected plant material will be taken to Provo, Utah, generally on a weekly basis, and checked against specimens in the Brigham Young University Herbarium whenever the identification warrants verification. The proposal includes curriculum vitae of the scientists involved with the study: Bertrand F. Harrison, Stanley L. Welsh, Robert H. Foster, and Dan A. Foster.
