Description: The National Resources Inventory covers non-federal land in the United
States - some 75 percent of the country's land base - and is conducted
every five years by the USDA Natural Resources Conservation Service in
cooperation with Iowa State University. It captures data from 800,000
statistically selected locations on land cover, land use, soil
erosion, prime farmland soils, wetlands, habitat diversity, selected
conservation practices, and other natural resource information. The
information is statistically reliable for national, statewide, and
multi-county use.

Description: The Natural Resources Conservation Service is a Federal agency that
works in partnership with the American people to conserve and sustain
our natural resources.
