1997 National Resources Inventory (NRI)

The National Resources Inventory covers non-federal land in the United States, some 75 percent of the country's land base, and is conducted every five years by the USDA Natural Resources Conservation Service in cooperation with Iowa State University. Nationally it captures data from 800,000 statistically selected locations on land cover, land use, soil erosion, prime farmland soils, wetlands, habitat diversity, selected conservation practices, and other natural resource information. In Indiana there are 5800 sites for collecting information. The information is statistically reliable for national, statewide, and multi-county use.
