For well over a century, the Night Parrot lured its seekers into Australia's vast, arid outback. From the beginning it was a mysterious bird. Fewer than 30 specimens were collected before it all but disappeared, offering only fleeting glimpses and the occasional mummified body as proof of its continued existence. Protected by spinifex and darkness, the parrot attained almost mythical status: a challenge to birdwatchers and an inspiration to poets, novelists and artists. Night Parrot documents the competitiveness and secrecy, the triumphs and adventures of the history of the bird and its followers, culminating in the recent discovery of live birds at a few widely scattered locations. It describes what we are now unravelling about the mysteries of its biology and ecology and what is still left to learn. Complemented by guest essays, illustrations and photographs from a wide variety of sources, this book sheds light on Australia's most elusive bird.

Drylands are a sizeable part of the world's potentially arable land. They vary from the hyper-arid regions of the classic deserts of Africa and Asia to the more common semi-arid and sub-humid areas that support extensive agricultural systems dependent on rainfall or irrigation. Following their successful and innovative work The Economics of Dryland Management the editors have assembled twenty case studies from nine countries in the continents of Africa, Asia, North America and Australia. They help to explore more fully the costs of land degradation and illustrate the economics of reclamation, rehabilitation and prevention. The cases in this book present a rich, varied and readable survey of a wide range of drylands and their resources. Originally published in 19990

In eastern Australia, grassy eucalypt woodlands have been under severe pressure from agricultural development, with problems of land degradation and species decline being most severe in the cropping lands of south-eastern Australia. Managing and Conserving Grassy Woodlands describes a set of principles that will enable landholders to maintain or increase productivity without compromising ecological sustainability, and at the same time maintaining a substantial proportion of the native flora and fauna. The book provides the technical foundations underpinning the principles and explains the importance of planning at a landscape scale. Each major principle is addressed in a separate chapter which explains the scientific understanding behind the principle and which discusses some of the issues relating to its practical application. Additional chapters outline the basic ecological concepts underpinning the principles and the responses of landholders who have had the opportunity to discuss and reflect on the principles. For those interested in translating the principles into a property plan, a final chapter explores the steps that can be taken. Managing and Conserving Grassy Woodlands is intended for those at the interface of disciplinary research and on-ground application, whether they are working in research, regional planning, extension, landcare or land management.

This work is intended for advanced readers interested in methods of sustainable land management - the prevention and control of land degradation. It offers a coherent view of the situation concerning land degradation and the human response to the problem. It is generally recognized that technological solutions alone cannot solve the problems of land degradation. This book discusses the role of land use and land management policies, programmes, insitutional innovations, and economic incentives for the control and prevention of land degradation. Special attention is given to legal issues at the international level and in individual countries.

This book should be of value to anyone interested in bird evolution and taxonomy, biogeography, distributional history, dispersal and migration patterns. It provides an up-to-date synthesis of current knowledge on species formation, and the factors influencing current distribution patterns. It draws heavily on new information on Earth history, including past glacial and other climatic changes, on new developments in molecular biology and palaeontology, and on recent studies of bird distribution and migration patterns, to produce a coherent account of the factors that have influenced bird species diversity and distribution patterns worldwide.Received the Best Bird Book of the Year award for 2004 from British Birds magazine. * Winner of the British Birds/British Trust for Ornithology, Bird Book of the Year 2004!* The first book to deal comprehensively with bird speciation and biogeography* Up-to-date synthesis of new information* Clearly written* No previous book covers the same ground* Many maps and diagrams* Makes difficult and widely scattered information accessible and easily understood* A sound base for future research* Takes full account of recent developments in molecular biology

Human impact on natural landscapes through urbanization and agricultural expansion are becoming more and more dramatic and are the cause of serious environmental problems. This volume examines the effect of landscape disturbance on plant and animal diversity in the five mediterranean-climate regions of the world. It begins with three introductory chapters broadly reviewing the issues of landscape degradation. Further contributions describe regional land use conflicts in each of the five regions. Landscape disturbance and plant diversity, and landscape disturbance and animal diversity are treated in separate chapters. Four contributions deal with demography and ecophysiology in vegetation succession following disturbance. The volume closes with a consideration of the future addressing aspects of environmental politics.

This volume is one of a number of publications to carry the results of the first research programme of the Royal Swedish Academy of Science's Beijer Institute. The Institute was formed in 1991 in order to promote interdisciplinary research between natural and social scientists on the interdependency between economic and ecological systems. In its first research programme, the Biodiversity Programme, the Institute brought together a number of leading economists and ecologists to address the theoretical and policy issues associated with the current high rates of biodiversity loss in such systems - whether the result of direct depletion, the destruction of habitat, or specialisation in agriculture, forestry and fisheries. l This volume reports some of the more policy-oriented work carried out under the programme. The broad aim of the programme is to further our understanding of the causes and consequences of biodiversity loss, and to identify the options for addressing the problem. The results have turned out to be surprising to those who see biodiversity loss primarily in terms of the erosion of the genetic library. In various ways the work carried out under the programme has already begun to alter our perception of where the problem in biodiversity loss lies and what policy options are available to deal with it. Indeed, the programme has provided a powerful set of arguments for reappraising not just the economic and ecological implications of biodiversity loss, but the whole case for development based on specialisation of resource use.

Social historians will look back on the 1980s as a period when a global consciousness of the environment developed. Stimulated by major issues and events such as oil and chemical spills, clearing of rainforests, pollu tion of waterways, and, towards the end of the decade, concern over the greenhouse effect, concern for the environment has become a major social and political force. Unfortunately, the state of the environment and its future manage ment are still very divisive issues. Often, at a local level, concern for the environment is the antithesis of development. The debate usually focusses on the possible negative environmental impacts of an activity versus the expected positive economic impacts. It is a very difficult task to integrate development and conservation, yet it is towards this objec tive that the sustainable development debate is moving. The issues in the central wheatbelt of Western Australia are typical of the environment versus development debate. It is undoubted that the development of the area, which involved clearing the native vegetation, has had a major impact upon the original ecosystems. Many of the natural habitats are threatened and local extinction of flora and fauna species is a continuing process. Moreover, there are clear signs that land degradation processes such as dryland salinity are depleting the land resource.
