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.

The new National Resources Inventory is out and packed with data samples from 800,000 locations across the country. Among the 1982 to 2010 highlights: land dedicated for fruits, nuts, and flowers increased from 124.8 million in 2007 to 273.8 million in 2010 and cropland acreage increased by about 2 million acres from 2007 to 2010 after a steady decline over the previous 25 years.

National 2010 NRI Summary Report (PDF; 7.7 MB)

The 2014 NRI Rangeland Resource Assessment is also now available. Results in this report are derived from NRI rangeland data collected on-site from 2004 to 2011. The findings reported here focus on key issues in rangeland science, including rangeland health, non-native plant species, non-native and native invasive plant species, bare ground, inter-canopy gaps and soil surface aggregate stability. Regional and some State level results are included.

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.
