The National Resources Inventory (NRI) is an appraisal of natural resource conditions and trends on nonfederal land conducted by the U.S. Department of Agriculture’s Natural Resources Conservation Service (NRCS). The 2017 NRI summary report, released in September 2020, includes details about land cover and use, soils, erosion, wetlands and conservation practices for the 48 contiguous states, Hawaii and Caribbean Territories. It also documents changes in land cover/use at the national level for six reporting periods: 1982—1997, 1997—2002, 2002—2007, 2007—2012, 2012—2017, and 1982—2017.
