definition: The National Resources Inventory (NRI) is a compilation of natural resource information on non-Federal land in the United States--about 75 percent of the total land area. Conducted by the U.S. Department of Agriculture's Natural Resources Conservation Service in cooperation with the Iowa State University Statistical Laboratory, this inventory captures data on land cover and use, soil erosion, prime farmland soils, wetlands, habitat diversity, selected conservation practices, and related resource attributes. Data are collected every 5 years from the same 800,000 sample sites in all 50 States, Puerto Rico, the U.S. Virgin Islands, and some Pacific Basin locations. The NRI is a statistically based survey that has been designed and implemented using scientific principles to assess conditions and trends of soil, water, and related resources. The NRI provides a record of trends in the Nation's resources over time and documents conservation accomplishments as well. At each sample point, information is available for 1982, 1987, 1992, and 1997, so that trends and changes in land use and resource characteristics over 15 years can be examined and analyzed. The NRI provides information for addressing agricultural and environmental issues at national, regional, and State levels. Purpose and Use: The NRI is conducted to obtain scientific data that is valid, timely, and relevant on natural resources and environmental conditions. Through legislation--the Rural Development Act of 1972, the Soil and Water Resources Conservation Act of 1977, and other supporting acts--Congress mandates that the NRI be conducted at intervals of 5 years or less. Information derived from the NRI is used by natural resource managers; policymakers; analysts; consultants; the media; other Federal agencies; State governments; universities; environmental, commodity, and farm groups; and the public. These constituents use NRI information to formulate effective public policies, fashion agricultural and natural …
