This current NRI database should be used to compare 2012 conditions with those for earlier years. Comparisons using NRI data published prior to 2012 can produce incorrect inferences. Statistical estimation and quality assurance procedures employed for the NRI survey program help ensure that trends reported using NRI data reflect true changes in resource conditions. 2/ Includes ceded land; excludes leased land and submerged land. 3/ Land cover is the vegetation or other kind of material that covers the land surface. Land use is the purpose of human activity on the land; it is usually, but not always, related to land cover. The NRI uses the term land cover/use to identify categories that account for all the surface area of the United States. 4/ Conservation Reserve Program (CRP) Land under a federal program established under the Food Security Act of 1985 to assist private landowners to convert highly erodible cropland to vegetative cover for 10 years. 5/ These estimates are not reliable. The margin of error is equal to or greater than the estimate so the confidence interval includes zero. 6/ Prime farmland has the best combination of physical and chemical characteristics for producing food, feed, forage, fiber, and oilseed crops and is also available for these uses. 7/ Includes estuarine deepwater, and all Riverine and Marine systems.
