Available in PDF, EPUB and Kindle. Book excerpt: Wildlife managers are on the front lines of the effort to conserve wildlife and are required to do so cost-effectively. This dissertation consists of three manuscripts that integrate economics and ecology to inform cost-effective wildlife management. The first and second manuscripts focus on identifying cost-effective wildlife management plans. The third manuscript considers wildlife management under uncertainty. The first manuscript integrates economic and ecological principles to identify cost-effective management plans. Bio-physical simulation and regression analysis are paired to approximate response functions for an important duck species, the mallard (Anas platyrhynchos). Response functions are then included in an economic optimization model to estimate management cost functions. Approximated response functions indicate that mallard response is non-linear due to diminishing marginal productivity and interdependence of management activities. This results in non-linear cost functions, which imply that the standard approach of treating ecological production and economic costs independently may result in inefficient management. The second manuscript extends the first by incorporating landscape heterogeneity. The same modeling approach is replicated for three landscapes that differ in their ecological and economic productivity. This approach demonstrates that taking advantage of landscape heterogeneity can generate cost savings if managers target multiple landscapes simultaneously. Additionally, management activities that do not interfere with agriculture are found to be highly cost-effective, suggesting that common ground exists between conservationist and private landowners. The first and second manuscripts assume that managers can predict wildlife response with certainty. The third manuscript illustrates the tradeoff between the risk and return to management when response is uncertain. Financial portfolio theory is adapted to account for diminishing marginal productivity and interdependence of management activities. An analytical model is used to determine how these properties alter the standard derivation of mean-variance efficient portfolios. This has implications for addressing uncertainty in many renewable resource contexts. Simulated data on mallards are used to apply the portfolio model to wildlife management. Results indicate that portfolio theory provides practical insights about managing wildlife under uncertainty.

Available in PDF, EPUB and Kindle. Book excerpt: This collection of new and classic essays by a group of distinguished economists and wildlife experts challenges the prevailing idea that wildlife and markets are inimical to one another, arguing that markets can play an important role in preserving animal species and their habitat. In fact, the editors argue, the late nineteenth-century slaughter of wild game occurred because common ownership gave no incentive for hunters to limit their take or for owners of habitat to invest in wildlife. Using case studies from North America and southern Africa, the essays discuss how 'enviro-capitalism' has been successfully implemented to encourage elephant and rhino preservation and look at the politics of the international ivory ban. They examine the historical role of incentive wildlife management and the problems with political wildlife management that do not take into account the ownership of habitat.
Download or read book Correction Lines written by Curt Meine and published by Island Press. This book was released on 2013-04-10 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last fifteen years have been a period of dramatic change, both in the world at large and within the fields of ecology and conservation. The end of the Cold War, the dot-com boom and bust, the globalizing economy, and the attacks of September 11, among other events and trends, have reshaped our worldview and the political environment in which we find ourselves. At the same time, emerging knowledge, needs, and opportunities have led to a rapid evolution in our understanding of the scientific foundations and social context of conservation. Correction Lines is a new collection of essays from one of our most thoughtful and eloquent writers on conservation, putting these recent changes into perspective and exploring the questions they raise about the past, present, and future of the conservation movement. The essays explore interrelated themes: the relationship between biological and social dimensions; the historic tension between utilitarian and preservationist approaches; the integration of varied cultural perspectives; the enduring legacy of Aldo Leopold; the contrasts and continuities between conservation and environmentalism; the importance of political reform; and the need to "retool" conservation to address twentyfirst-century realities. Collectively the essays assert that we have reached a critical juncture in conservation—a "correction line" of sorts. Correction Lines argues that we need a more coherent and comprehensive account of the past if we are to understand our present circumstances and move forward under unprecedented conditions. Meine brings together a deep sense of history with powerful language and compelling imagery, yielding new insights into the origins and development of contemporary conservation. Correction Lines will help us think more clearly about the forces that have changed, and are changing, conservation, and inspire us to address current realities and future needs.

Available in PDF, EPUB and Kindle. Book excerpt: The general interest and attention paid to the use of the renewable natural resources of the world have increased greatly during the last decades. This is due to the environmental dilemma into which mankind has got itself by the total disregard of ecological facts and laws, the underprizing of natural resources and the overemphasis on economic develop ment, coupled with unimpeded rapid population growth and the preponderance of material istic consumption-oriented attitudes. The management and use of natural resources such as forests, grasslands, rivers and lakes were formerly considered purely in a financial context, whereas latterly, a consciousness of their social function and the indirect economic benefits which can be derived from them has developed. Thus, as regards these traditional resources, multi-use concepts comprising eco nomically oriented utilisation as well as recreational, educational and social use have be come widely accepted. Conservation of natural resources for sustainable consumptive as well as non-consumptive uses has been recognised as a key element for maintaining eco nomic development all over the world. Fortunately, the industrialised countries have started to apply this principle themselves and in their technical and financial aid to the developing Third World countries. This is manifest from policy documents such as the World Bank Policy on Development of Wild Lands, issued in 1987.

Download or read book The North American Model of Wildlife Conservation written by Shane P. Mahoney and published by JHU Press. This book was released on 2019-09-10 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: The foremost experts on the North American Model of Wildlife Conservation come together to discuss its role in the rescue, recovery, and future of our wildlife resources. At the end of the nineteenth century, North America suffered a catastrophic loss of wildlife driven by unbridled resource extraction, market hunting, and unrelenting subsistence killing. This crisis led powerful political forces in the United States and Canada to collaborate in the hopes of reversing the process, not merely halting the extinctions but returning wildlife to abundance. While there was great understanding of how to manage wildlife in Europe, where wildlife management was an old, mature profession, Continental methods depended on social values often unacceptable to North Americans. Even Canada, a loyal colony of England, abandoned wildlife management as practiced in the mother country and joined forces with like-minded Americans to develop a revolutionary system of wildlife conservation. In time, and surviving the close scrutiny and hard ongoing debate of open, democratic societies, this series of conservation practices became known as the North American Model of Wildlife Conservation. In this book, editors Shane P. Mahoney and Valerius Geist, both leading authorities on the North American Model, bring together their expert colleagues to provide a comprehensive overview of the origins, achievements, and shortcomings of this highly successful conservation approach. This volume • reviews the emergence of conservation in late nineteenth–early twentieth century North America • provides detailed explorations of the Model's institutions, principles, laws, and policies • places the Model within ecological, cultural, and socioeconomic contexts • describes the many economic, social, and cultural benefits of wildlife restoration and management • addresses the Model's challenges and limitations while pointing to emerging opportunities for increasing inclusivity and optimizing implementation Studying the North American experience offers insight into how institutionalizing policies and laws while incentivizing citizen engagement can result in a resilient framework for conservation. Written for wildlife professionals, researchers, and students, this book explores the factors that helped fashion an enduring conservation system, one that has not only rescued, recovered, and sustainably utilized wildlife for over a century, but that has also advanced a significant economic driver and a greater scientific understanding of wildlife ecology.

Available in PDF, EPUB and Kindle. Book excerpt: Farming and the Fate of Wild Nature addresses an urgent and complex issue facing communities and cultures throughout the world: the need for heightened land stewardship and conservation in an era of diminishing natural resources. Agricultural lands in rural areas are being purchased for development. Water scarcities are pitting urban and development expansion against agriculture and conservation needs. The farming population is ageing and retiring, while those who remain struggle against low commodity prices, international competition, rising production costs, and the threat of disappearing subsidies. We are living amidst a major extinction crisis--much of it driven by agriculture--as well as an increasing shift toward a global urban populace. The modern diet, driven by a grain-fed livestock industry, is no longer connected with the ecosystems that support it. In international circles, experts are arguing that further intensification of agriculture (through industrialization and genetic modification) will be necessary to both feed an exploding human population and to save what is left of wild biodiversity. This book takes up where its predecessor, the award-winning Farming with the Wild, left off. Featuring a wide range of in-depth essays, articles, and other materials by such authors as Aldo Leopold, Wendell Berry, Michael Pollan, Fred Kirschenmann, and Daniel Imhoff, this book persuasively demonstrates that farm and ranch operations which coexist with wild nature are necessary to sustain biodiversity and beauty on the landscape. In fact, as this invaluable educational resource demonstrates, they are essential in the challenge of building sane, healthy, and hopeful human societies.

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.
