Book Description
The bestselling RSPB Handbook of British Birds is the most comprehensive reference for birdwatchers of all levels of interest and experience. Now in its fifth edition, it remains the most accessible field guide to more than 300 bird species likely to be encountered in Britain and Ireland. Alongside artworks depicting all common plumages, the detailed text describes each bird's behaviour, habitat, voice, breeding biology, longevity and seasonal movements, as well as other useful information. The guide also includes UK population trends and up-to-date distribution maps. Completely revised and updated, this fifth edition also features new artwork and comparison spreads, additional rarities and the most recent taxonomic order, as well as each species' conservation status, a summary of the threats UK species are currently facing and details of what conservationists are doing to help. A new lay-flat binding has also been used, creating easier access to the species accounts at home or in the field.

Book Description
The landscape of Britain has been irreversibly changed over the last century. Modern agriculture, urban expansion, industry and transport have all left their mark, altering the face of the countryside forever. Shifting with the changing scene, the fortunes of Britain and Ireland's bird populations have fluctuated dramatically over the years. As current farming practices have evolved, the natural habitats and breeding patterns of many species have been disrupted. Urban and industrial growth has brought with it the pressures of new land use, pesticides, pollution and human interference. The activities of sportsmen, collectors and farmers have also taken their toll over the years. The new Poyser title The Historical Atlas of Breeding Birds in Britain and Ireland 1875-1900 is a fascinating book resulting form years of meticulous research by the author, Simon Holloway, who provides an absorbing account of the distribution changes of Britain and Ireland's birds over the last quarter of a century. Large colour distribution maps and their accompanying text paint a species-by-species picture of a period which completely transformed the landscape of this country. It is, says Natural World magazine, "a classic case of 'why did no one write this book before?'...The experienced birder, using a knowledge of species requirements, can only marvel at what the long-vanished landscapes were then like." Birdwatch praises Simon Holloway's achievement, saying: "This book brings together so much information from disparate sources, and its status maps present such a clear picture of our late Victorian avifauna, that it should take its place beside the BTO atlases on the bookshelf." While Birdwatching adds: "If you are interested in the historical side of birds and their populations this book will be an endless source of fascination." As with all Poyser publications, the attention to detail, the lovingly produced illustrations and the sheer breadth of knowledge demonstrated by the autho

Book Description
The Atlas plots the results of the survey organised by the BTO and the IWC during the years 1968-72. Over 250 maps show the distribution of 218 species. This companion volume to The Atlas of Wintering Birds in Britain and Ireland is derived from yearly surveys of breeding birds in Britain and Ireland during 1968-72, organised by the British Trust for Ornithology and the Irish Wildbird Conservancy. Each of the 3,862 10-km squares of Britain and Ireland was visited during the five years and the resulting records (over 285,000) are summarised in the maps. The full-page maps plot the known distribution of all but 11 of the 229 breeding species located during the survey period. Each map has an accompanying text which describes the species' habitat, the problems involved in proving breeding, the historical background to the species' range and any changes in its numbers. The probable reasons for these changes are discussed and an attempt made to assess the total number of birds for each species. Jacket design by Robert Gillmor.

Book Description
Biological homogenization is the dominant process shaping the future global biosphere. As global transportation becomes faster and more frequent, it is inevitable that biotic intermixing will increase. Unique local biotas will become extinct only to be replaced by already widespread biotas that can tolerate human activities. This process is affecting all aspects of our world: language, economies, and ecosystems alike. The ultimate outcome is the loss of uniqueness and the growth of uniformity. In this way, fast food restaurants exist in Moscow and Java Sparrows breed on Hawaii. Biological homogenization qualifies as a global environmental catastrophe. The Earth has never witnessed such a broad and complete reorganization of species distributions.

Book Description
Wild birds are counted for a wide variety of reasons and by a bewildering array of methods. However, detailed descriptions of the techniques used and the rationale adopted are scattered in the literature, and the newcomer to bird census work or the experienced bird counter in search of a wider view, may well have difficulty in coming to grips with the subject as a whole. While not an end in itself, numerical and distributional census work is a fundamental part of many scientific and conservation studies, and one in which the application of given standards is vital if results are not to be distorted or applied in a misleading way.This book provides a concise guide to the various census techniques and to the opportunities and pitfalls which each entails. The common methods are described in detail, and illustrated through an abundance of diagrams showing examples of actual and theoretical census studies. Anyone with a bird census job to plan should be able to select the method best suited to the study at hand, and to apply it to best effect within the limits inherent in it and the constraints of the particular study.The Royal Society for the Protection of Birds and the British Trust for Ornithology have for many years pioneered the collaboration of amateurs and professionals in various census studies. Three members of their staff, each with extensive field experience, now pool the knowledge of these investigations to lay the groundwork for sound census work in future years.

Book Description
Monitoring has become fashionable. Business now talks about monitoring its activities, efficiency, costs and profits. The National Health Service is monitoring general practices and hospitals; it is keen to have more information about efficiency and the duration of stay of patients in different hospitals undergoing different types of treatment. These activities are usually carried out in relation to specific objectives with the aim of making activities more cost effective and competitive. Does the same apply in biology, ecology and nature conservation? Or, are we still enjoying conducting field surveys for the fun of it, at best with rather vague objectives and saying to our colleagues that we do our work because we need to know what is there? This book is an opportunity to consider some of the reasons why monitoring is important, how it differs from survey, how it may be able to answer specific questions and help with site management or problem solving. It will explore some of the taxa that are suitable for recording and how you may actually set about doing it. It is not intended as a catalogue of techniques but we will in each chapter give you sources of material so that with the minimum of effort you will be able to proceed with an efficient, relevant and not too time consuming monitoring programme. Some of the points that you need to consider before starting are also set down in the synthesis at the end of the book.

Book Description
Periodic comprehensive overviews of the status of the diverse organisms that make up wildlife are essential to determining trends, threats and future prospects. Just over 25 years ago, leading authorities on different kinds of wildlife came together to prepare an assessment of their status of a wide range of organisms in Great Britain and Ireland in The Changing Flora and Fauna of Britain, also edited by Professor David L. Hawksworth CBE. Now, in The Changing Wildlife of Great Britain and Ireland, he has gathered together some of the original and also new contributors to review changes since that time and look to the future. Contributions range from viruses, diatoms, fungi, lichens, mites and nematodes; through butterflies, dragonflies, flies and slugs; to flowering plants, ferns, mammals, birds and fish. The state of knowledge in different groups is assessed, and the effectiveness of statutory and other measures taken to safeguard wildlife considered. The picture is far from bleak, ameliorating sulphur dioxide levels have benefited sensitive lichens and mosses in a dramatic way, water quality improvement has been beneficial, there have been few certain extinctions and rediscoveries of species thought to have been lost. Biodiversity Action Plans have also benefited targeted species, but habitat restoration and management for some is not always good for others. But there are worrying trends in declining populations, with an increasing number being regarded as threatened or endangered, especially in agricultural areas, and where woodland management has changed, particular threats from introduced species, and concern over the effects of climate change. Some of the smaller organisms remain poorly known, a situation unlikely to change as expertise in many is scant or being lost. This stock-check and look to the future will be a key source book to conservationists, naturalists, and professional biologists for many years to come.
