National Resources Inventory

The National Resources Inventory is an inventory of land cover and use,soil erosion, prime farmland, wetlands, and other natural resource characteristics 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 to determine the conditions and trends in the use of soil, water, and related resources nationwide and statewide. The data is used in national, state, and local planning, university research, and private sector analysis. They help shape major environmental and land-use decisions.
