This book was released on 1995-10-13 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: From the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal. Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.

Available in PDF, EPUB and Kindle. Book excerpt: Threatened and endangered species recovery programs consume increasing resources. Even so, there is increased concern about actual and projected biodiversity losses and in the success of recovery programs in reversing these trends. In this paper, we use a panel data set and ordered probit econometric methods to statistically examine the determinants of the 1990-2002 biennial U.S. Fish and Wildlife Service (FWS) recovery scores for up to 225 vertebrate species listed as threatened or endangered under the Endangered Species Act. We find that species-specific spending is a significant determinant of species' recovery scores and that increased spending reduces the probability that FWS will classify a species as extinct or declining. The evidence does not support the hypothesis that increased spending increases the probability that a species is stable or improving. Other FWS' actions have significant and substantive influences on improved recovery scores. These include progress on or completion of a recovery plan and achievement of stated recovery objectives. We find evidence that species achieve better recovery scores if FWS considers them to have high recovery potential and that species whose recovery is judged by FWS to be in conflict with economic activity are more likely to be classified as extinct. Our evidence does not support the conclusion that critical habitat designation promotes species' recoveries or prevents species' declines. We also report a new finding that recovery success varies across FWS administrative regions.

Available in PDF, EPUB and Kindle. Book excerpt: The Endangered Species Act of 1973 (ESA) is one of the most cherished and reviled laws ever passed. It mandates protection and preservation of all the nation’s species and biodiversity, whatever the cost. It has been a lightning rod for controversy and conflicts between industry/business and environmentalists. In this volume, leading Endangered Species Act experts interpret and propose legislative and administrative changes to prepare the ESA for future challenges. They explore regulations on avoiding harm to and producing benefits for species, cooperation between state and federal agencies, scientific analyses, and the necessary politics to enact their ideas. This is a call to action to chart an enlightened future for the Endangered Species Act that embraces the nation’s moral commitment of 50 years ago to address species extinction constructively, mindful of biodiversity, and as a fixture among the nation’s values and needs. The interconnected web of life includes all living species that depend on each other for survival, us among them. The stakes—our very future—are too high to ignore.
Download or read book Conservation Biology for All written by Navjot S. Sodhi and published by OUP Oxford. This book was released on 2010-01-08 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.
Download or read book Essays on the Economics of Conservation written by Ryan Michael Finseth and published by . This book was released on 2018 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: We develop a general model for optimal recovery planning for an endangered species that seeks to satisfy delisting criteria at minimum economic cost. We apply our model to the management of the California condor (Gymnogyps californianus), a critically endangered species under threat from lead poisoning. Given the threats currently facing the condor, state and local governments have begun to regulate the use of lead ammunition within the condor's habitat. Currently, there is a significant amount of uncertainty regarding the effectiveness of the proposed regulations in reducing lead levels in the environment. An optimal recovery plan minimizes discounted expected costs over a specified time horizon. We numerically solve for optimal recovery plans for single and multiple managed subpopulations with infinite and finite time horizons. The optimal recovery plan is sensitive to the form and parameterization of the objective function. Solving model formulations with unique variants of the objective function generates a set of recovery plans that vary in probability of delisting and expected management cost. We present a discrete-time, stochastic model for the management of multiple subpopulations of an endangered species to achieve multiple, predetermined delisting criteria. Numerically solving the model results in recovery plans that optimally allocate resources across multiple subpopulations of a listed species in an attempt to achieve exogenous delisting criteria. We apply the model to the recovery of the California condor and present the results from multiple case studies, 1) two identical subpopulations and a single delisting criterion, 2) two spatially distinct subpopulations and a single delisting criterion, and 3) two subpopulations with two delisting criteria. We show that in the two subpopulation model with a single delisting criteria, optimal recovery plans allocate resources solely to the subpopulation with the larger population level in the current time period, and abandon the lower population to extinction. Captive breeding populations provide insurance against existing threats (and potential shocks) to wild subpopulations, and a source of potential translocations to augment wild subpopulations. We explore entry/exit decisions faced by planners when simultaneously managing both wild and captive populations of the California condor. Previous work on the optimal management planning for the California condor assumes that translocation costs are variable. However, it may be more realistic to model the cost of captive breeding populations as an annual fixed cost, where the cost does not depend on the number of individuals produced. Our model determines the conditions for `exiting' or ceasing captive breeding operations for a finite recovery planning horizon. We explore multiple case studies, including recovery planning when the state space is completely observable and under mixed observability. Simulation analysis is used to illustrate how recovery plans are implemented over time and to highlight the tradeoffs between management intensity and probability of achieving delisting criteria.

Available in PDF, EPUB and Kindle. Book excerpt: In the face of so many unprecedented changes in our environment, the pressure is on scientists to lead the way toward a more sustainable future. Written by a team of ecologists, Monitoring Animal Populations and Their Habitats: A Practitioner’s Guide provides a framework that natural resource managers and researchers can use to design monitoring programs that will benefit future generations by distilling the information needed to make informed decisions. In addition, this text is valuable for undergraduate- and graduate-level courses that are focused on monitoring animal populations. With the aid of more than 90 illustrations and a four-page color insert, this book offers practical guidance for the entire monitoring process, from incorporating stakeholder input and data collection, to data management, analysis, and reporting. It establishes the basis for why, what, how, where, and when monitoring should be conducted; describes how to analyze and interpret the data; explains how to budget for monitoring efforts; and discusses how to assemble reports of use in decision-making. The book takes a multi-scaled and multi-taxa approach, focusing on monitoring vertebrate populations and upland habitats, but the recommendations and suggestions presented are applicable to a variety of monitoring programs. Lastly, the book explores the future of monitoring techniques, enabling researchers to better plan for the future of wildlife populations and their habitats. Monitoring Animal Populations and Their Habitats: A Practitioner’s Guide furthers the goal of achieving a world in which biodiversity is allowed to evolve and flourish in the face of such uncertainties as climate change, invasive species proliferation, land use expansion, and population growth.

Available in PDF, EPUB and Kindle. Book excerpt: This title was first published in 2000: The noble goals embodied in the Endangered Species Act are colliding with financial and social realities. Citizens increasingly face the costs of current policies, while initiatives which fail to respect liberty and property meet serious resistance at every turn. Despite widespread verbal support for saving species ’at any cost’, when trade-offs become obvious, and values compete, support for these policies evaporates. This edited collection examines ethically and materially responsible approaches to this problem, written by leading international figures from a variety of disciplines. The result is the most comprehensive and constructive analysis of the effectiveness and viability of endangered species protection available.
