Montana National Resources Inventory (NRI)The 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. 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 Unites States. The survey is conducted by the Natural Resources Conservation Service (NRCS) in cooperation with Iowa State University's Center for Survey Statistics and Methodology. Most of the NRI data is now collected using photo interpretation at three regional NRCS Remote Sensing Laboratories. The photo interpretation for NRI segments located in Montana is done at the Remote Sensing Laboratory in Portland Oregon. Local NRCS staff in Montana provide data for all other inventory elements. National Resources Inventory Process For more information see the National NRI web site. National Resources Inventory ResultsThe NRI was conducted on a five-year cycle for 800,000 sample sites during the period 1982 to 1997, but is now conducted annually for slightly less than 25 percent of these same sample sites. Results from the 1997 NRI are available at the national, regional, state, and substate level. Some 2003 State level results for land use and erosion are available on the National NRI web site. However, the estimates represent 2003 conditions only and cannot be used to evaluate change from previous inventory cycles. State level change estimates and associated trending information from the 2003 Annual NRI will be available for release spring 2007.
