When the first edition of this book was published in 1977--to overwhelming critical and popular acclaim--it was the only publication to analyze wildlife law comprehensively as a distinct component of federal environmental law. The second edition, published in 1983, provided a thorough and authoritative update. Since then the intense public interest in wildlife law has been reflected in a tremendous growth in both litigation and new legislation. This, the third edition, thoroughly reexamines the field and provides a comprehensive review of this complex and turbulent area of the law.
