From the National Resources Conservation Service and the US Department of Agriculture, the recently released 1997 National Resources Inventory provides a statistically-based account of "conditions and trends of soil, water, and related resources" on US non-federal lands, including data on wetlands, conservation practices, farmland, land use, and more. The makers claim, "it is the most comprehensive database of its kind ever attempted anywhere in the world." The site provides the complete report (.pdf format), as well as links offering discussion in the form of an introduction, background, data gathering, statistical design, statistical estimation, a glossary, and results and analysis. Individual sections contain additional documentation. This is an unusual and comprehensive resource for those in need of national resources statistics.
