"David Hellyer-physician, naturalist, world traveler, horseman, boxing enthusiast, and creator of Northwest Trek wildlife sanctuary-has lived one of the most varied and useful lives of anyone I know. His memoirs reflect the dry humor, the astonishing range of expertise, and the combination of charm, creativity, and energy that have made his careers possible."-Murray Morgan, author of Skid Road "His richly anecdotal story is a valuable contribution to the history of the Pacific Northwest."-Victor B. Scheffer, author of The Shaping of Environmentalism in America "During the past century, many great men with passion and spirit have made an effort to help preserve the wildlife on our planet. David Hellyer is one of these men. His book, At the Forest's Edge, is a great collection of remembrances of his life, leading up to the opening of the Northwest Trek Wildlife Park in Washington State. His enduring memories of times, places, and people make for a fascinating tale."-Charles R. Faust, Zoological Society of San Diego

The Eastern Arc Mountains of East Africa are one of the 17 most threatened tropical ecosystems or hotspots worldwide. This is the first book to examine in detail current threats as well as approaches for conserving biological diversity in this global biodiversity hotspot. This volume synthesizes existing information on the biodiversity of the Eastern Arc Mountains, outlines processes that adversely affect this diversity, and suggests potential approaches for promoting its conservation. While the geographic focus of this book is the Eastern Arc forests, the problems, principles, and approaches discussed in relationship to conserving biodiversity have applicability to nearly all tropical forests worldwide.

The demand for comparable, long-term, high quality data on forest ecosystems' status and changes is increasing at the international and global level. Yet, sources for such data are limited and in many case it is not possible to compare data from different monitoring initiatives across space and time because of methodological differences. Apart from technical manuals, there is no comprehensive multidisciplinary, scientific, peer-reviewed reference for forest monitoring methods that can serve and support the user community. This book provides in a single reference the state-of-the-art of monitoring methods as applied at the international level. The book present scientific concepts and methods that form the basis of the transnational, long-term forest monitoring in Europe and looks at other initiatives at the global level. Standardized methods that have been developed over two decades in international forest monitoring projects are presented. Emphasis is put on trans-nationally harmonized methods, related data quality issues, current achievements and on remaining open questions. A comprehensive overview of needs, requirements, organization and possible outcomes of an integrated monitoring program Tested and quality assured, internationally harmonized methodologies based on a complete revision of existing methods carried out in 2009-2011 Connection with monitoring results allows assessment of the potential of the monitoring method
