The nation’s forest census has been in place since the 1930s and provides excellent scientific continuity. The program is the fundamental national and state supported data collection, analysis, and reporting system regarding the past, current, and potential future condition of the nation’s forests. Data gathered through FIA are essential to understanding long-term forest health, management potential, and socioeconomic contribution of the nation’s forests.
FIA enables forest managers and the natural resource community to understand the scope and scale of trends and changes in forest conditions and to make projections of future conditions. Funding for FIA supports state and private lands, which account for two-thirds of America’s forests and provide public benefits such as clean air and water, wildlife habitat, outdoor recreation, jobs and wood products.
