National Resources Inventory

National Resources Inventory

The National Resources Inventory (NRI) is statistical survey of land cover and use, soil erosion, prime farmland, wetlands, and other natural resource characteristics and trends on non-Federal rural land in the United States. The NRI provides a record of the Nation's conservation accomplishments and future program needs.

Inventories have been conducted at 5-year intervals by the U.S. Department of Agriculture's Natural Resources Conservation Service (NRCS) to determine the conditions and trends in the use of soil, water, and related resources nationwide and statewide.

NRI data are statistically reliable for national, regional and state analysis. The NRI was scientifically designed and conducted and is based on recognized statistical sampling methods. The data are used in national, state, and local planning, university research, and private sector analysis.
