The new chief of the National Park Service said he will limit use of some major parks to reduce human impact. “When in any doubt, we must err on the side of preservation,” William Penn Mott Jr., 75, said after a three-day visit to Yellowstone National Park. And a private conservation group warned in a study to be released today that the national park system is not prepared for new threats posed by heavy use of the parks and development of neighboring lands. The Conservation Foundation proposed a 10-year, $500-million effort to restore park resources and acquire more land.
