The eight species of bear live in more than 65 countries or autonomous regions in four continents, in a variety of habitats from tropical rainforests to arctic ice. Numerous human cultures around the world symbolically or physically try to incorporate the power of bears into their people. But all species have declined in numbers due to the impacts of human activities, including: habitat alteration and destruction; unregulated killing of bears for sport; sale of parts for medicinal products; and protection of crops or livestock. This plan sets out priority actions for bear conservation, including surveys of status and distribution; cooperative projects and cross-border management; research projects to develop basic knowledge of habitat requirements; and documentation of the impacts of illegal trade. As bears are umbrella species in most of the ecosystems they inhabit, conservation of bears and their habitats will preserve biodiversity in these areas and focus management efforts on preserving watershed resources that also sustain human populations

The loss and fragmentation of natural habitats is one of the major issues in wildlife management and conservation. Habitat "corridors" are sometimes proposed as an important element within a conservation strategy. Examples are given of corridors both as pathways and as habitats in their own right. Includes detailed reviews of principles relevant to the design and management of corridors, their place in regional approaches to conservation planning, and recommendations for research and management

IUCN has been described as "the conservation world's best-kept secret". It is the oldest global conservation body, founded 50 years ago. For half a century it has been a "green web", linking governments, non-governmental organizations and the world's leading individual conservationists and providing a unique forum where they can meet and debate. It has prepared global strategies and originated some of the world's most important environmental laws. It is the world authority on threatened species and on national parks and protected areas. Its influence has been enormous - and yet few people outside the conservation world understand what it is and what it does. This book describes the history of IUCN, drawing on a mass of hitherto-unpublished sources and the memories of many who have played a key part in world conservation down the years. But it also sets the "green web" in context, reviewing how it has influenced the whole world environmental movement in a half century that has unquestionably been the "age of environment"
