The principles discussed can be applied to wilderness areas within the national forests and areas under the control of the Bureau of Land Management and the U.S. Fish and Wildlife Service. One objective of the text is to give students an understanding of the historical development of law enforcement in the national parks. A second objective is to provide information on the law enforcement problems that are pertinent to park backcountry and how they are being solved. A third objective is to train students in the procedures that are necessary to gain compliance from violators. A crucial issue addressed by the text is the maintaining of a balance between visitor freedom and park preservation. Students are also instructed in the skills needed for proactive backcountry law enforcement. Various issues of concern to officers in a backcountry jurisdiction are discussed, including drug manufacturing, archaeological theft, off-road vehicle use, criminal violations, and violations by those unfamiliar with backcountry laws and regulations. The text also familiarizes students with the basics of constitutional law, criminal law, natural resource law, and the U.S. Code of Federal Statutes and Regulations. Chapter references
