Book Description
This report provides information about the extent to which personal watercraft and snowmobiles are used on federal lands, the process by which decisions about their use are made, and the extent of monitoring being done in areas where their use is allowed. It focuses on the four major federal land management agencies, which manage about 95% of all federal lands: the Bureau of Land Management, the Fish and Wildlife Service, and the National Park Service, all in the Dept. of the Interior; and the Forest Service in the Dept. of Agriculture. Appendix I describes the report's scope and methodology; appendix II contains agency-by-agency responses to the questionnaire.

Book Description
A variety of air pollutants are emitted into the atmosphere from human-caused and natural emissions sources throughout the United States and elsewhere. These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.
