This work is designed to teach natural resources professionals how to be more effective in solving conservation and environmental policy problems. Its presentation of basic concepts, case studies and "real world concerns" offers a deeper understanding of the policy process and should be useful to students and practitioners in such fields as wildlife biology, conservation biology, forestry, range management, ecosystem management and sustainable development. Tim Clark begins by describing the challenges faced by natural resources professionals. He then explains how the substance and process of policy analysis and decision making can be improved by using a policy sciences framework that takes into account biological, social, political and institutional considerations. Finally he reflects on how issues of human rights and morality should affect natural resources management and policy analysis.
