The Forest Inventory and Analysis (FIA) is a congressionally mandated program of the U.S.D.A. Forest Service that collects, compiles, summarizes, and distributes high-quality data, reports, and scientific analyses on the status, trend and potential futures of our country’s forest resources. Over the past eight decades, you—individuals and corporations – who own most of the 800 million acres of U.S. forests, have generously allowed us to access a permanent plot, a small spot on your land, to measure and assess trees, understory vegetation and down wood. We value and appreciate this cooperation from private landowners as this information continues to be essential to attaining a complete understanding of all U.S. forests and how they have changed and will change over time.
