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.
