National Resources Inventory

The National Resources Inventory (NRI) is a compilation of natural resource information on non-federal land throughout the United States.  This inventory captures data on land cover and use, soil erosion, prime farmland, wetlands, habitat diversity, selected conservation practices and related resource attributes at more than 800,000 scientifically selected sample sites.  It is conducted by NRCS every five years.

The NRI provides a record of trends in the nation's resources over time. It is also an excellent record of conservation accomplishments and changes in land use and resource characteristics.  Because the NRI is based on recognized statistical sampling methods and is scientifically designed and executed, NRI data are valuable in analyzing issues at national, regional and state levels.
