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
Preserving Yellowstone's Natural Conditions describes in fascinating detail the historical origins and development of wildlife management in Yellowstone National Park, alongside shifting understandings of nature in science and culture. James A. Pritchard traces the idea of "natural conditions" through time, from the introduction of this concept by early ecologists in the 1930s. He tells several overlooked stories of Yellowstone wildlife, including a sensational scientific hunt for bears with bow and arrow, and the episode of the predator pelicans, which facilitated a fundamental shift toward protection of all wildlife in Yellowstone, and for the National Park Service as a whole. A prolonged debate regarding the elk herd on Yellowstone's northern range is addressed, along with the origins of the notion of natural regulation, and the reasons for ending direct reductions of elk. This story emphasizes how ecological science came to Yellowstone and to the National Park Service, subsequently developing over a period of decades. In the new afterword to this book Pritchard summarizes recent developments in wildlife science and management--such as the "ecology of fear" and trophic cascades--and discusses historical continuities in the role of the park as a wildlife refuge and the inestimable values of the park for wildlife conservation.
