The H. John Heinz III Center for Science, Economics and the Environment was a nonpartisan nonprofit organization headquartered in Washington, D.C.

The Heinz Center is best known as the creator of the State of the Nation's Ecosystems reports, which have become seminal references for U.S. policy makers and environmental managers[1] on the conditions of and trends in U.S. ecosystems and habitats and the goods and services they provide.

Senator H. John Heinz III[2] of Pennsylvania after his untimely death in 1991,[3] and closed in 2013.

The State of The Nation's Ecosystems was designed to provide an impartial and comprehensive understanding of the state of and trends in ecosystems,[5] much the way decision makers use gross domestic product (GDP) to gauge national economic health.

[8] The reports were created with the input of more than 300 scientific experts,[9] who agreed upon a set of 108 indicators to track trends in the health of distinct U.S. ecosystems—coasts and oceans, farmlands, forests, freshwaters, grasslands and shrublands, and urban and suburban land-use types—on the national, regional, and local levels.
