This study describes the results of a project to monitor British butterflies, based upon frequent counts at 90 sites throughout the UK. It surveys trends in numbers, the extinction and foundation of populations, flight periods, local distribution, migration and other aspects of population ecology. Practical problems encountered during the conservation of butterflies at individual sites are outlined. The relevance of this type of monitoring for an understanding of climatic warming is also described.

The assessment of how and why species and communities are threatened is crucial to rational decision making about the implementation of management plans for their conservation. There is an increasing interest in the importance of conserving the diversity of species and community assemblages in the world - often called biodiversity. This book looks at the issues involved in the prioritization of these resources. An updated expansion of "Ecological Evaluation for Conservation" by the same author, it contains examples and case studies from around the world, illustrating the issues faced by conservationists. It summarizes a large amount of material from the scientific literature and should not only appeal to conservation biologists and wildlife managers, but also to students of conservation biology.

This text applies research knowledge to the solution of practical problems facing wildlife conservation in freshwater habitats. Subjects covered include: evaluation of the conservation interest of sites; practical protection and management of freshwater habitats; and species conservation. Using a large number of photographs and examples from freshwater habitats worldwide, this text brings together expertise and information to produce a practical and comprehensive account of freshwater conservation management.

This work describes the selection, setting up and technique for manage ment of marine protected sites internationally. Principles are supported by practical case studies drawn from the main marine regions of the world. This book should be of interest to conservation biologists; marine biologists; managers of marine and coastal areas; marine and environment scientists; ocean and coastal planners and policy decision makers.

Forest wildlife conservation is critically required in many parts of the world today. This text presents a merger between the elements of wildlife conservation and habitat conservation, and how this can be used to promote the conservation of vertebrates in forests around the world. This book should be of interest to conservation biologists; wildlife managers; policy decision makers (forestry, departments of wildlife management, fisheries etc.); nature conservancy personnel; ecologists; foresters; wildlife biologists; and rangers.

This volume sets out to provide an overview of recent research on all aspects of amphibian ecology and behaviour and to illustrate its application to practical conservation measures for this major group of animals. Its broad scope makes it of relevance to students of general biology, ecology and conservation, but also to professionals in industries and agencies involved with environmental issues and nature conservation.

Insects are the major component of the world's biodiversity. By their vast numbers, they are vital determinants of the terrestrial ecological processes. This work covers a wide range of topics from single species to landscape conservation, and from rare butterflies to the benefits-and-risks of biocontrol agents.

Previously published in hardback and now made available in paperback, this ground-breaking book is a must for all interested in butterflies, whether as conservation biologist, amateur or professional entomologist or as a student studying the phenomenon of butterfly populations as part of a number of biology, ecology or conservation courses. Recently, many British butterflies have suffered severe declines whole others have flourished and expanded in range. This is the first book to describe the results from a British scheme to monitor butterflies during this period of change. The Monitoring Scheme, initiated in 1976 by the senior author is based on frequent counts at some 90 sites throughout Britain. The combined efforts of both amateurs and professionals have thus produced a dataset with no equivalent elsewhere in the world. The book therefore provides a unique perspective on trends in numbers, extinction and foundation of populations; flight periods, local distributions, migration and other aspects of population ecology. Practical problems encountered during the conservation of butterflies of individual sites are outlined. The relevance of this monitoring for an understanding of the effects of the weather - climatic warming - is described.

Wildlife utilization is commonly referred to as good or bad strategy for conservation when, in fact, the circumstances of use are so diverse that generalizations are not easy to support. The purpose of the book is to show that utilization schemes can be good, bad or mixed from a conservation viewpoint. The important thing is to determine the factors which contribute to success. The book will thus introduce the subject of wildlife utilization and, based on a small but careful selection of case studies, will reveal the range of circumstances and animal types involved. A synthesis will attempt to determine the criteria for success as well as the pitfalls and constraints.

One of the major challenges of sustainable development is the interdisciplinary nature of the issues involved. To this end, a team of conservation biologists, hunters, tourist operators, ranchers, wildlife and land managers, ecologists, veterinarians and economists was convened to discuss whether wildlife outside protected areas in Africa can be conserved in the face of agricultural expansion and human population growth. They reached the unequivocal - if controversial - conclusion that wildlife can be an economic asset, especially in the African savannas, if this wildlife can be sustainably utilized through safari hunting and tourism. Using the African savannas as an example, this text shows that in many instances sustainable wildlife utilization comprises an even better form of land use than livestock keeping. Even when population pressure is high, as in agricultural areas or in humid zones, and wild animal species can pose a serious cost to agriculture, these costs are mainly caused by small species with a low potential for safari hunting.Although ranching has a very low rate of return and is hardly ever profitable, the biggest obstacle to the model of sustainable wildlife use outlined in this text is from unfair competition from the agricultural sector, such as subsidies and lack of taxation, resulting in market distortion for wildlife utilization. This book thus gives valuable evidence for a different way of working, providing arguments for removing such distortions and thereby facilitating financially sound land use and making it a rationally sound choice to conserve wildlife outside protected areas. The team of authors, most of whom came together at a workshop to thrash out the ideas that were then developed into the various chapters, has written a superb account of recent research on this complex subject, resulting in a book that is a major contribution to our understanding of sustainable use of land. The important conclusion is that wildlife conservation can be possible for landholders and local communities if they have a financial interest in protecting wildlife on their lands.

The international perspective for this book is the unprecedented level of concern over deforestation, recognized by the meeting of world leaders at the 1992 Earth Summit, in Rio do Janeiro, and culminating in the appoint­ ment of the Intergovernmental Panel on Forests (IPF), under the auspices of the UN Commission on Sustainable Development. The wide range of issues covered by the authors in this volume reflects the breadth of the interna­ tional debate, from national policies and activist campaigning, through eco­ nomic and social objectives, to the sustainable management of forest and soil resources. Since the conservation campaigns of the 1980s, the focus of international concern has widened from tropical rain forests to all forest formations, in all regions, with increased recognition of global values and common responsibil­ ities. However, while forest cover in some temperate countries is increasing, irrational deforestation, at historically unprecedented levels of damage to biodiversity and to other environmental values, remains most acute in tropi­ cal countries, where the need to use the natural resources for sustainable development is greatest, and the capability weakest. While accepting the urgency of the situation, and the need for greater coherence of action at a global level, the 1997 report of the IPF to the UN Commission emphasized the powers and responsibilities of national governments, and the importance of National Forest Programmes, but with the fuller participation of local communities, and with enhanced access to international assistance.

Reproduction is essential to the continuation and evolution of life on this planet and is therefore a centrally important process in the conservation of wildlife. However, reproductive mechanisms are well understood in only a handful of vertebrate species, mostly domestic livestock and laboratory animals. This means that attempts to develop and implement management policies for wildlife conservation, and especially for endangered species that, by definition, are difficult to study, are often based on poor data or no data at all. In Reproductive Science and Integrated Conservation leading authorities provide glimpses of reproductive diversity in fishes, amphibia, reptiles, birds and mammals. Conservation plans are founded on the assumption that reproduction will be successful, but what if it fails? This book reviews the many factors that influence reproduction, including genetics, behaviour and nutrition, and experts assess the potential conservation relevance of the recent rapid advances in reproductive technology and medicine.

Phylogeny is a potentially powerful tool for conserving biodiversity. This book explores how it can be used to tackle questions of great practical importance and urgency for conservation. Using case studies from many different taxa and regions of the world, the volume evaluates how useful phylogeny is in understanding the processes that have generated today's diversity and the processes that now threaten it. The novelty of many of the applications, the increasing ease with which phylogenies can be generated, the urgency with which conservation decisions have to be made and the need to make decisions that are as good as possible together make this volume a timely and important synthesis which will be of great value to researchers, practitioners and policy-makers alike.

Human-wildlife conflict is a major issue in conservation. As people encroach into natural habitats, and as conservation efforts restore wildlife to areas where they may have been absent for generations, contact between people and wild animals is growing. Some species, even the beautiful and endangered, can have serious impacts on human lives and livelihoods. Tigers kill people, elephants destroy crops and African wild dogs devastate sheep herds left unattended. Historically, people have responded to these threats by killing wildlife wherever possible, and this has led to the endangerment of many species that are difficult neighbours. The urgent need to conserve such species, however, demands coexistence of people and endangered wildlife. This book presents a variety of solutions to human-wildlife conflicts, including novel and traditional farming practices, offsetting the costs of wildlife damage through hunting and tourism, and the development of local and national policies.

Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This 2006 book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources.

The sustainable exploitation of the marine environment depends upon our capacity to develop systems of management with predictable outcomes. Unfortunately, marine ecosystems are highly dynamic and this property could conflict with the objective of sustainable exploitation. This book investigates the theory that the population and behavioural dynamics of predators at the upper end of marine food chains can be used to assist with management. Since these species integrate the dynamics of marine ecosystems across a wide range of spatial and temporal scales, they offer new sources of information that can be formally used in setting management objectives. This book examines the current advances in the understanding of the ecology of marine predators and will investigate how information from these species could be used in management.

Modern zoos and aquaria are playing an increasingly active and important role in protecting and managing global biodiversity. Many zoos include wildlife conservation in their mission and have started changing the focus of their institutions in order to increase even further the benefits of their activities for in situ wildlife conservation. With these developments, the following searching questions are now being asked: What is the true role of zoos in conservation? How can they contribute more significantly to global conservation efforts? What are the unique attributes of zoos that can be applied in the conservation landscape? And should zoos be doing more? In parallel with this voluntary movement, legal requirements for zoos to support conservation in the wild are also becoming more stringent. This 2007 book defines a conservation vision for zoos and aquaria that will be of interest to those working in zoos, alongside practitioners and researchers in conservation.

As evidence for the rapid loss of biological diversity strengthens, there is widespread recognition of the need to identify priorities and techniques for conservation action that will reverse the trend. Much progress has been made in the development of quantitative methods for identifying priority areas based on what we know about species distributions, but we must now build an understanding of biological processes into conservation planning. Here, using studies at global to local scales, researchers consider how conservation planners can deal with the dynamic processes of species and their interactions with their environment in a changing world, where human impacts will continue to affect the environment in unprecedented ways. This book will be a source of inspiration for postgraduates, researchers and professionals in conservation biology, wildlife management and ecology.

Carnivores are the focus of intense attention and resources in conservation biology. It is often argued that, because carnivores are at the top of the food chain, if they are protected, then other taxa will also be afforded adequate protection. Carnivores are also charismatic and compete with humans for dwindling space and environmental resources. In the past 10 years, theoretical and empirical studies on carnivores have developed very quickly. This volume reviews and summarises the current state of the field, describes limitations and opportunities for carnivore conservation, and offers a conceptual framework for future research and applied management. As such it will be of interest to students and researchers of conservation biology, mammalogy, animal behaviour, ecology and evolution.

How does an understanding of the behaviour of a given animal species contribute to its conservation? The answer to this question has profound consequences for our efforts to conserve endangered species. Behaviour and Conservation links the extraordinary advances that have been made in behavioural ecology over the last 30 years with the new discipline of conservation biology. It uses the power of an evolutionary approach to help solve problems in practical conservation, and suggests a new direction for behavioural ecology. The book addresses the ways in which behaviour and conservation interact, investigating the conservation impact of people, habitat loss and fragmentation, threats to wild populations of animals, conservation priorities and the use of behavioural approaches for conservation applications. Leading authorities in animal behaviour outline the relevance of their work to key problems in animal conservation for all researchers and students in the behavioural sciences and conservation biology.

Coral reefs are the 'rain forests' of the ocean, containing the highest diversity of marine organisms and facing the greatest threats from humans. As shallow-water coastal habitats, they support a wide range of economically and culturally important activities, from fishing to tourism. Their accessibility makes reefs vulnerable to local threats that include over-fishing, pollution and physical damage. Reefs also face global problems, such as climate change, which may be responsible for recent widespread coral mortality and increased frequency of hurricane damage. This book, first published in 2006, summarises the state of knowledge about the status of reefs, the problems they face, and potential solutions. The topics considered range from concerns about extinction of coral reef species to economic and social issues affecting the well-being of people who depend on reefs. The result is a multi-disciplinary perspective on problems and solutions to the coral reef crisis.

One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.

It is widely accepted among conservation biologists that genetics is, more than ever, an essential and efficient tool for wild and captive population management and reserve design. However, a true synergy between population genetics and conservation biology is lacking. Following the first International Workshop on Population Genetics for Animal Conservation in 2003 at the Centro di Ecologia Alpina, Trento, Italy (recently incorporated into the Edmund Mach Foundation), the scientific committee felt that, given the global urgency of animal conservation, it was imperative that discussions at the conference were made accessible to graduate students and wildlife managers. This book integrates 'the analytical methods approach' with the 'real problems approach' in conservation genetics. Each chapter is an exhaustive review of one area of expertise, and a special effort has been made to explain the statistical tools available for the analysis of molecular data as clearly as possible. The result is a comprehensive volume of the state of the art in conservation genetics, illustrating the power and utility of this synergy.

Forests host a disproportionate share of the world's biodiversity. They are increasingly being seen as a refuge for genetic diversity, native species, natural structures, and ecological processes. Yet, intensive forestry threatens their value for biodiversity. The authors present concepts, approaches and case studies illustrating how biodiversity conservation can be integrated into forest management planning. They address ecological patterns and processes taking place at the scale of landscapes, or forest mosaics. This book is intended for students and researchers in conservation biology and natural resource management, as well as forest land managers and policy makers. It presents examples from many forest regions and a variety of organisms. With contributions from researchers that are familiar with forest management and forest managers working in partnership with researchers, this book provides insight and concrete tools to help shape the future of forest landscapes worldwide.

Dugongs and manatees, the only fully aquatic herbivorous mammals, live in the coastal waters, rivers and lakes of more than 80 subtropical and tropical countries. Symbols of fierce conservation battles, sirenian populations are threatened by multiple global problems. Providing comparative information on all four surviving species, this book synthesises the ecological and related knowledge pertinent to understanding the biology and conservation of the sirenia. It presents detailed scientific summaries, covering sirenian feeding biology; reproduction and population dynamics; behavioural ecology; habitat requirements and threats to their continued existence. Outlining the current conservation status of the sirenian taxa, this unique study will equip researchers and professionals with the scientific knowledge required to develop proactive, precautionary and achievable strategies to conserve dugongs and manatees.
