Forest Inventory and Analysis Program The Forest Inventory and Analysis Program is a long-term science program administered by the United States Department of Agriculture United States Forest Service that produces systematic information about the status and trends of forests in the United States, including the National Forest System, Puerto Rico, and the U.S. Virgin Islands. It supports decisions by linking data users such as the United States Congress, Environmental Protection Agency, National Aeronautics and Space Administration, National Oceanic and Atmospheric Administration, and state agencies including the California Department of Forestry and Fire Protection, New York State Department of Environmental Conservation, and Minnesota Department of Natural Resources. The program’s outputs inform stakeholders including Society of American Foresters, American Forest Foundation, National Wildlife Federation, World Resources Institute, and the Nature Conservancy.

Overview

The program conducts periodic inventories across ownerships such as the Bureau of Land Management holdings, National Park Service units, and private lands held by entities like Weyerhaeuser, Rayonier, and Hancock Natural Resource Group. Its scope spans ecological provinces defined by organizations such as the United States Geological Survey and the Environmental Systems Research Institute, integrating classification schemes from the International Union for Conservation of Nature and the Society for Ecological Restoration. Data themes include tree species composition referenced against taxonomies used by the Missouri Botanical Garden, structural metrics comparable to datasets from the Smithsonian Institution and the Royal Botanic Gardens, Kew, and carbon accounting aligned with protocols by the Intergovernmental Panel on Climate Change and the Global Carbon Project.

History and Development

Origins trace to inventory efforts by the McSweeny Commission era and New Deal programs such as the Civilian Conservation Corps and priorities set by the Weeks Act; later methodological formalization involved collaborations with academic institutions including Yale University School of the Environment, Oregon State University College of Forestry, University of Minnesota Department of Forest Resources, and University of California, Berkeley. The program evolved through partnerships with federal programs like the Forest Service Northeastern Research Station and the Pacific Northwest Research Station, and through legislative influences such as the Forest and Rangeland Renewable Resources Planning Act of 1974. International comparisons engaged organizations including the Food and Agriculture Organization, Canadian Forest Service, and the European Forest Institute.

Methods and Data Collection

Field sampling employs plot designs comparable to those used by the National Ecological Observatory Network and integrates remote sensing from platforms such as Landsat, Sentinel-2, and airborne lidar campaigns like those conducted by the National Center for Airborne Laser Mapping and Optech. Tree measurements follow standards from the American Society for Testing and Materials and species identifications cross-reference keys from the New York Botanical Garden and taxonomic treatments by United States National Herbarium. Geographic information is managed with tools from Esri and analysis workflows mirror approaches in studies by the Smithsonian Tropical Research Institute and the Woods Hole Oceanographic Institution. Quality assurance protocols align with guidelines from the National Academy of Sciences and data stewardship reflects practices used by the Library of Congress and the National Archives.

Data Products and Reporting

The program produces national, regional, and state reports similar in utility to publications by the Congressional Research Service and statistical outputs akin to those from the Bureau of Labor Statistics and United States Census Bureau. Tabular and spatial products are used by analysts at the World Bank, International Monetary Fund, and nongovernmental organizations such as Conservation International and Greenpeace. Time-series and trend analyses have been cited in studies produced by Harvard University, Stanford University, Massachusetts Institute of Technology, and policy reports from the Brookings Institution and the Council on Environmental Quality.

Applications and Uses

Practitioners in forestry and ecology apply the data for wildfire risk modeling alongside tools from the National Interagency Fire Center and collaborations with the United States Geological Survey wildfire science program. Carbon inventories support participation in carbon markets overseen by entities such as the California Air Resources Board and inform climate assessments by the United Nations Framework Convention on Climate Change and IPCC reports. Conservation planning leverages outputs in coordination with National Audubon Society, Audubon Society, World Wildlife Fund, and state fish and wildlife agencies like the Texas Parks and Wildlife Department. Academic research citing the program appears in journals published by Elsevier, Nature Publishing Group, and the European Geosciences Union.

Governance and Funding

Governance involves federal leadership from the United States Department of Agriculture and operational management by the United States Forest Service Research and Development. Funding streams include congressional appropriations overseen by subcommittees of the United States House Committee on Appropriations and the United States Senate Committee on Appropriations, cooperative agreements with state forestry agencies, and grants from foundations such as the Packard Foundation and the Gordon and Betty Moore Foundation. Data partnerships engage interagency collaborations with the United States Fish and Wildlife Service, Natural Resources Conservation Service, and international partners like the Canadian Forest Service and European Space Agency.
