USDA ReleaseS State-by-State National Resources Inventory on Soil Erosion and Land Cover and Use

WASHINGTON, January 16, 2007—The Department of Agriculture’s Natural Resources Conservation Service
(NRCS) today released state-by-state results on soil erosion and land cover and use for the conterminous United
States from its 2003 National Resources Inventory (NRI). The NRI provides comprehensive and statistically
reliable information on various natural resource conditions and trends on nonfederal lands.

“This information is the first release of any state-level estimates from the Annual NRI inventory process,” said
NRCS Chief Arlen L. Lancaster.

The first NRI was conducted in 1977 and, until 1997, was done every 5 years. Starting in 2000, NRCS began
the transition to an annual inventory cycle. NRCS conducts the NRI in cooperation with Iowa State University’s
Center for Survey Statistics and Methodology.

The annual NRI uses a sub-sample of the total complement of NRI sample sites, and requires several years of
cumulative data collection to provide estimates at a state or sub-state scale that are in accordance with Quality of
Information guidelines established by the Office of Management and Budget and USDA.

This latest release represents 2003 conditions only. It does not include a trend analysis for individual states and
cannot be used to evaluate change from previous inventory cycles. State-level change estimates and associated
trending information from the 2003 NRI will be available for release later this winter. Trend analysis information at
national and major-river-basin scales is available for the 2003 NRI on the NRI Website.

NRCS provides products and services that enable people to be good stewards of the nation’s soil, water, and
related natural resources on non-Federal lands. Additional information about NRI and other USDA conservation
programs is available at USDA Service Centers nationwide and online at:
