Papers from a summit, "Science for Parks, Parks for Science: the next century," organized by University of California, Berkeley, in partnership with the National Geographic Society and the National Park Service and held 25-27 March 2015 at the University of California, Berkeley.

Now in a fully updated edition, this invaluable reference work is a fundamental resource for scholars, students, conservationists, and citizens interested in America's national park system. The extensive collection of documents illustrates the system's creation, development, and management. The documents include laws that established and shaped the system; policy statements on park management; Park Service self-evaluations; and outside studies by a range of scientists, conservation organizations, private groups, and businesses. A new appendix includes summaries of pivotal court cases that have further interpreted the Park Service mission.

When the Challenge was first funded in FY 2000, Congress requested that the National Park Service report on Challenge-related expenditures and accomplishments. This report responds to that request and offers a summary of the state of natural resources across the National Park System in FY 2010 by providing financial details and accomplishments for Servicewide natural resource stewardship programs funded by the Challenge as well as other sources.
