This publication is directed to the analysis of the selection, management, and utilization of Biosphere Reserves as viewed by scientists from the United States and the Union of Soviet Socialist Republics. Soviet papers focus on types of research and monitoring programs that should be developed on Biosphere Reserves, with emphasis on their use in pollutant monitoring. The nature of the U.S. Biosphere Reserves and their current and potential value for research, education,and biological preservation is considered in the U.S. papers. An additional paper provides an international perspective on U.S. and Soviet collaboration in the field of Biosphere Reserves. Characteristics of Soviet Biosphere Reserves are described in an appendix.

IUCN's Protected Areas Management Categories, which classify protected areas according to their management objectives, are today accepted as the benchmark for defining, recording, and classifying protected areas. They are recognized by international bodies such as the United Nations as well as many national governments. As a result, they are increasingly being incorporated into government legislation. These guidelines provide as much clarity as possible regarding the meaning and application of the Categories. They describe the definition of the Categories and discuss application in particular biomes and management approaches.

During the 1960s and 1970s, rapidly growing environmental awareness and concern created unprecedented demand for ecological expertise and novel challenges for ecological advocacy groups such as the International Union for Conservation of Nature and Natural Resources (IUCN). This book reveals how, despite their vast scientific knowledge and their attempts to incorporate socially relevant themes, IUCN experts inevitably struggled to make global schemes for nature conservation a central concern for UNESCO, UNEP and other intergovernmental organizations.
