National Resources Inventory
The National Resources Inventory (NRI) is a statistical survey of land use and natural resource conditions and trends on U.S. non-federal lands. Non-Federal lands include privately owned lands, tribal and trust lands and lands controlled by state and local governments. Non-Federal lands represent nearly 75 percent of the Nation's total land area. The NRI serves as the Federal Government's principal source of information on the status, conditions, and trends of soil, water, and related resources in the United States. The primary purpose of the NRI is to support agricultural and environmental policy development and program implementation. The survey is conducted by the Natural Resources Conservation Service in cooperation with Iowa State University's Center for Survey Statistics and Methodology. This partnership ensures that the NRI employs well-established scientific survey principles.

Grazing Land Field Study
The Grazing Land Field Study is a vital component of the NRI. Since 2003, onsite grazing land data has been collected in 20 states, including Montana. Grazing Land Specialists visit each sample site and collect data using protocols established and researched by the NRCS, the USDA Agricultural Research Service, and the USDA Bureau of Land Management. Types of data collected at each sample point include: Land cover and land use, landscape and soils, ecological site information, rangeland health, invasive/noxious plants, conservation practices, resource concerns, plant composition and production.
