Book excerpt: "This publication is a guide to understanding the National Environmental Policy Act (NEPA). This publication covers NEPA, the Endangered Species Act, and the Wilderness Act. It focuses on the environmental work of the 562 Indian tribes that play an important role in the environmental arena. The book uses chiefly Indian and tribal cases (162 case studies in all) to illustrate the finer points of NEPA doctrine as it exists in the broader field of Indian law."--The publisher's website.
