Introduction

This report presents summary results from the 2010 National Resources Inventory (NRI). The 2010 NRI is the latest in a series of natural resource inventories conducted by the U.S. Department of Agriculture’s Natural Resources Conservation Service (NRCS). It provides updated information on the status, condition, and trends of land, soil, water, and related resources on the Nation’s non-Federal lands. Non-Federal lands include privately owned lands, tribal and trust lands, and lands controlled by State and local governments. The 2010 NRI provides nationally consistent data for the 28-year period 1982–2010. This current NRI database should be used to compare 2010 conditions with those for earlier years. Comparisons using NRI data published prior to 2010 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; the “NRI Survey Process” section of this report provides further explanation.

This report presents national- and state-level estimates from the 2010 NRI for the 48 conterminous states, Hawaii, and the Caribbean Territories for basic NRI data themes, including changes and trends in land cover/use, irrigation, land capability class and subclass, prime farmland, soil erosion, and wetlands. These basic findings will be supplemented during the first part of 2014 by Web modules on various topics of interest, including soil erosion, land use, wetlands, and development of non-Federal rural land. These supplemental materials plus information on how to request additional 2010 NRI estimates can be found on the NRI Web site at http://www.nrcs.usda.gov/technical/nri/. The NRI survey program is scientifically based, employing recognized statistical sampling methods. The 2010 NRI was conducted by NRCS in cooperation with Iowa State University’s Center for Survey Statistics and Methodology (ISU-CSSM), which serves

as the NRI Statistical Unit providing statistical and survey methods support for the NRI survey program. Background

The results of the 1934 National Erosion Reconnaissance Survey, the first formal study of erosion in the United States, were instrumental in the passage of the Soil Conservation Act of 1935. That Act established the Soil Conservation Service (SCS), NRCS’s predecessor agency. Since its founding, SCS/NRCS has conducted periodic inventories of the Nation’s natural resources. The 1945 Soil and Water Conservation Needs Inventory (CNI), another reconnaissance study, was the foundation for the 1958 and 1967 CNIs, which represented the agency’s first efforts to collect data nationally for scientifically selected field sites. The 1975 Potential Cropland Study examined the conversion of the Nation’s best farmland to urban development and provided statistical data on the potential for converting other lands to cropland. Periodic NRIs were conducted in 1977, 1982, 1987, 1992, and 1997. Since 2000, NRI data have been gathered annually, though major releases of these data continue to be reported at 5-year intervals. This 2010 NRI release is an exploration into the feasibility and usefulness of more frequent releases. The NRI survey framework was also used to conduct several less intensive, special-issue inventories during the 1990s; these special studies investigated topical matters of concern (such as wetland conversions) and supplemented the periodic NRI surveys. Numerous legislative acts have mandated that NRCS collect natural resources data. The Rural Development Act of 1972 directed the Secretary of Agriculture to implement a land inventory and monitoring program and to issue a report on the conditions and trends of soil, water, and related resources at intervals not exceeding 5 years. The Soil and Water Resources Conservation Act (RCA) of 1977 and other supporting legislation augmented the statutory mandate for periodic assessment of the Nation’s natural resources. To fulfill this requirement, the NRI program was

developed to provide critical information regarding natural resources and to supplement the NRCS Soil Survey Program. NRI Survey Process

NRI survey objectives and procedures have evolved continuously over the past 33 years. The NRI process initiated in 1977 was developed in response to several significant Congressional edicts; it was based upon scientific and rigorous sample survey protocols, and was influenced by the earlier experiences of the CNIs (1950s and 1960s) and the 1975 Potential Cropland Study. USDA and agency officials initiated the NRI process in 1977 through the construction of a permanent statistical sampling frame that could be used to periodically obtain scientifically credible information on conditions and trends of soil, water, and related resources. Even though 1977 NRI data provided the foundation for the 1980 appraisal of natural resources required by the Soil and Water Resources Conservation Act (RCA) of 1977, it was determined that there were important data gaps and that the survey’s sample size should be significantly increased. The 1982 NRI utilized most of the survey methodology and protocols employed for the 1977 NRI, but the scope and sample size were increased to meet RCA demands and to also better address emerging issues such as permanent loss of agricultural land to nonagricultural uses. The 1982 NRI was eventually designed to establish a data base that would allow natural resource issues to be analyzed by portions of Major Land Resource Areas (MLRAs) within States. The initial desire was to have county-level reliability rather than the State-level reliability provided by the 1977 NRI, but it was determined that sufficient resources were not available; and the 1982 NRI sample design was ultimately a compromise because it provided the equivalent of multi-county level reliability [Nusser and Goebel (1997); Goebel (1998)]. Sample design The universe of interest for the NRI survey consists of all surface area (land and water) of the United States including all 50 States, Puerto Rico, the U.S. Virgin Islands, and certain Pacific Basin islands. The sample covers all land ownership categories including Federal, although NRI data collection activities have historically concentrated on non-Federal lands. The NRI sample was selected on a county-by-county basis, using a stratified, two-stage, area sampling scheme. The two-

stage sampling units are (1) nominally square segments of land, and (2) points within the segments. The segments are typically half-mile-square parcels of land equivalent to 160-acre quarter-sections in the Public Land Survey System, but there are many exceptions in the western and northeastern United States. Three specific sample point locations were selected for most selected segments, although two were selected for 40-acre segments in irrigated portions of some western States, and some segments originally contained only one sample point. Some modifications to the sample were made between 1982 and 1997. The 1997 NRI sample contained about 300,000 sample segments and 800,000 sample points. The NRI was conducted every 5 years from 1977 to 1997. Thereafter, an annual or continuous approach was initiated in 2000. This approach provides efficiencies in conducting the survey and balancing of resources, and also makes it easier for the NRI to respond to newly emerging resource issues. Each year a subset of between 71,000 and 72,000 segments from the 1997 sample is selected for observation. The subset is selected using a supplemented panel rotation design [Fuller and Breidt (1998); Breidt and Fuller (1999)]; this means that a core panel of about 40,000 segments is observed each year along with a different supplemental or rotation panel selected for each year. These panels are selected using stratification based upon geographical factors and historical data; for example, segments containing wetlands or land enrolled in the USDA Conservation Reserve Program (CRP) have a significantly higher chance of selection than those classified historically as forest land. Data collection Data for the 1982 NRI were collected by thousands of SCS field staff, supplemented by contractors and employees of other agencies working under the direction of SCS. Data collection started in spring 1980 and concluded in fall 1982; data collected prior to 1982 were reviewed to ensure that they reflected 1982 growing season conditions. For the 1987 NRI, data were collected by teams of trained personnel; remote sensing techniques were used to update 1982 conditions for about 30 percent of the sample sites. The use of remote sensing increased during the 1990s. Starting in 2000, special high-resolution imagery was acquired for each NRI sample site selected for that year’s annual sample.

For the 1997 NRI, 21 Inventory Collection and Coordination Sites (ICCS) were established and assigned oversight and management authorities for data gathering. Some sites assembled staffs at one central office, while others distributed staff among multiple office locations. Data gatherers entered all sample data directly into hand-held computers, which were programmed to provide an intelligent survey instrument with historic information, procedural logic, and checking routines for data completeness and consistency. The ICCS structure continued for the 2000, 2001, 2002, and 2003 Annual NRI data collection activities. As part of the 2004 NRCS reorganization, the agency established Remote Sensing Laboratories (RSLs) at Greensboro, NC; Fort Worth, TX; and Portland, OR. These units were designed, staffed, and equipped to take full advantage of modern geospatial technologies to facilitate efficient collection and processing of NRI data. They are staffed with permanent employees whose full-time job is NRI data collection and processing. Staffing includes NRCS employees who provide management support and technical expertise in agronomy, forestry, grazing land management, soil science, and biology; contract employees provide imagery preparation, photo interpretation, data gathering, and quality control services. Local NRCS staff utilize Field Office records and other materials to obtain certain data elements that are not easily obtained through photo interpretation, e.g., cropping histories, factors needed to populate erosion prediction models, participation in programs such as CRP and the Wetlands Reserve Program (WRP), and unique landscape features. Historical data and numerous types of auxiliary data are also utilized. Numerous quality control and quality assurance processes are performed by NRCS and contract staff as well as by the Statistical Unit and NRCS resource inventory specialists co-located with the Statistical Unit. Many of the quality assurance processes are embedded within the survey software developed by NRCS and the Statistical Unit. Intricate quality assurance processes have been developed to ensure that year-to-year differences in the data reflect actual changes in resource conditions, rather than differences in the perspectives of two different data collection specialists, or changes in technologies and protocols. The Annual NRI design also calls for annual collection of onsite data at subsets of the annual sample segments

and points. Protocols have been developed for rangelands and other grazing lands, and systematic collection of data has been in effect since 2003. Results from rangeland data collection activities are reported separately from the 2010 NRI results presented in this report. Protocols were also developed for cropland focusing on conducting farm owner/operator interviews designed to obtain detailed data on farming activities and conservation practices for a 3-year period for the field associated with an NRI sample point; interviews were conducted during 2003 – 2006 by trained enumerators working for USDA’s National Agricultural Statistical Service. Results from 2003 – 2006 data collection have been published from 2010 through the present as part of the Conservation Effects Assessment Project (CEAP). Similar data collection activities have become a standard part of the NRI survey process. Features of the NRI system The NRI is unique because of established linkages to the NRCS Soil Survey Program. Identifying soil occurrences and patterns and utilizing this knowledge to provide technical assistance in the development of conservation plans for landowners are primary agency functions. The NRI data gathering process relies heavily upon information contained in the NRCS Soil Survey Database. Information about specific properties and characteristics of the soil and surrounding landscapes is utilized to develop NRI data elements and interpretations. In addition, analysis and assessments utilizing NRI data can take advantage of the many soil interpretations and characteristics contained in the Soil Survey Database because each NRI sample point is linked to a specific soil in the database. Another special feature of the NRI is its true longitudinal nature. Even though many operational factors of the NRI survey program have evolved over the years, survey processes have been instituted to ensure that data contained within the 2010 NRI database are longitudinally consistent. For example, data collection protocols always include review and editing of historical data for the particular NRI sampling units being observed. Extensive deliberations were given to development of survey methods and protocols when the RSLs were established in 2004. Data collection tools, technologies, and staffing were completely different than those utilized for all previous NRI data collection activities. The first and most important business requirement was that the methods


4

and protocols developed and implemented must result in data that would provide legitimate trends over time. Statistical calibration and other modeling techniques are also used to ensure that NRI data provide legitimate estimates of change across multiple points in time. The NRI survey system utilizes points as the sampling units rather than farms or fields; land use and land unit boundaries change frequently in some parts of the country, and factors such as soil type do not follow human-induced boundaries such as land unit boundaries. Using points has allowed the NRI survey process to produce a database with dozens of factors (data elements) that are properly correlated over multiple years, so that analyses and inferences based upon the data are using proper combinations of longitudinal data. Because the NRI survey program is based upon scientific and rigorous sample survey protocols, it is of utmost importance to maintain and protect the integrity and confidentiality of the NRI data gathering sites. USDA and NRCS policy states that the NRI program will be conducted so as to “Maintain confidentiality of and administer access to information and materials pertaining to locations of data collection sites, with site locations identified by coordinate systems, depicted on maps or photographs, described by direct observation of local conditions and other materials assembled for inventories not constituting public information and to be used and managed only for official inventory purposes or for such purposes approved by the Secretary of Agriculture.” All NRI leaders and data gatherers are required to sign a confidentiality agreement, which defines levels of access to program-sensitive information for staff involved in NRI data collection. NRI data that identify owners, operators, or data collection sites are not to be released to the public. Certain confidentiality provisions have also been specified in the Farm Security Act of 2002 and the Food, Conservation, and Energy Act of 2008. Use and Interpretation of 2010 NRI Data

The NRI survey program provides scientifically valid, comprehensive, and relevant data on how U.S. non-Federal rural lands are being used, and on natural resource and environmental conditions for these lands, with the specific goal of supporting agricultural and environmental policy development and program implementation. Information derived from the NRI is

used by natural resource managers; policymakers and analysts; consultants; the media; other Federal agencies; State governments; universities; environmental, commodity, and farm groups; and the public. Historically, NRI information has been used to formulate effective public policies, to fashion agricultural and natural resources legislation, to develop State and national conservation programs, to allocate USDA financial and technical assistance in addressing natural resource concerns, and to enhance public understanding of natural resources and environmental issues. NRI data are designed to be part of the core components of the agency's strategic planning and accountability efforts, and to help assess consequences of existing legislative mandates, such as the appraisals required by the RCA and the periodic Farm Bills. The 2007 NRI provided the analytical foundation for the RCA Appraisal that USDA delivered to Congress in 2011 and the subsequent update of the National Conservation Program, which together provide guidance to USDA on conservation activities needed to meet the Nation’s long-term resource needs. The NRI will provide a statistical framework to evaluate proposed programs and policies relative to environmental considerations and various climate change scenarios, and relative to short- and long-term productivity and economic considerations. Adjustments to historic NRI data The 2010 NRI database has been designed for use in detecting significant changes in resource conditions relative to the years 1982, 1987, 1992, 1997, 2002, 2007, and 2010. All comparisons for two points in time should be made using the new 2010 NRI database. Comparisons made using data published for earlier NRIs may produce erroneous results because of changes in statistical estimation methodology and because all data collected prior to 2010 were simultaneously reviewed (edited) as 2010 NRI data were collected. Some edits were needed because of updated technical guidance; when standards are revised they are applied to both the historical data and the newly collected data. Statistical considerations Statistics derived from the NRI database are based upon data collected at sample sites located across all parts of the Nation. This means that all results are statistical estimates and contain some amount of statistical uncertainty. Interpretation of NRI results requires an

Summary Report

understanding of the amount of this uncertainty associated with each estimate, as well as an understanding of the inventory procedures. Since the NRI employs recognized statistical methodology, it is possible to quantify this statistical uncertainty. Margins of error are provided for all statistical estimates presented in this Summary Report; they are included below each estimate in smaller print as a plus or minus value. The margin of error is a commonly used measure of statistical uncertainty and can be used to construct a 95-percent confidence interval for an estimate. The lower bound of the confidence interval is obtained by subtracting the margin of error from the estimate; adding the margin of error to the estimate forms the upper bound. Measures of uncertainty (e.g., margins of error, standard errors, confidence intervals, coefficients of variation) should be taken into consideration when using NRI estimates. The margin of error is calculated by multiplying the standard error by the factor 1.96; a coefficient of variation is the relative standard for an estimate, usually in terms of percentages, and is calculated by taking 100 times the standard error and then dividing by the estimate. The precision of NRI estimates depends upon the number of samples within the region of interest, the distribution of the resource characteristics across the region, the sampling procedure, and the estimation procedure. Characteristics that are common and spread fairly uniformly over an area can be estimated more precisely than characteristics that are rare or unevenly distributed. Estimates of change between two points in time will be less precise (relatively) because the changes will be occurring on a smaller fraction of the landscape. Release of NRI results is guided by NRCS policy and is in accordance with OMB and USDA Quality of Information Guidelines developed in 2001. NRCS is releasing NRI estimates only when they meet statistical standards and are scientifically credible in accordance with these policies; also, measures of statistical uncertainty are provided for all 2010 NRI estimates released to the public. Interpretation of the data The NRI provides not only overall estimates of changes in resource conditions but also the dynamics of those changes. For example, gross losses and gains in cropland can be examined, and it can be determined why cropland was lost (say, to development), how

much had been classified as prime farmland, and where these losses occurred. For new cropland, the issue may be additional conservation and environmental concerns because the new cropland is more erodible, the soils are less productive and require higher levels of fertilization, or the land is sited in some other sensitive location. NRI survey results are based upon a particular set of definitions, protocols, and instructions. These have been developed to support NRCS programs and USDA analytical needs, so they differ in some cases from those used by other agencies. These differences need to be considered when analyzing and interpreting the data. Non-Federal Land: Most NRI estimates pertain only to non-Federal rural lands; non-Federal lands include privately owned lands, tribal and trust lands, and lands controlled by State and local governments. Some estimates, such as those for wetlands and deepwater habitats, cover water areas and all non-Federal lands including developed land. Soil Erosion: NRI erosion estimates are based upon erosion prediction models rather than on-site measuring of soil detachment, transport, and deposition. The erosion prediction models provide estimated average annual (or expected) rates based upon the cropping practices, management practices, and inherent resource conditions that occur at each NRI sample site. Climatic factors used in the erosion prediction equations (models) are based upon long-term average conditions and not upon one year’s actual events. NRI estimates of sheet and rill erosion utilize standard Universal Soil Loss Equation (USLE) technology rather than revised USLE (RUSLE) methodology so that it is possible to make comparisons back to the year 1982. Erosion estimates are currently made only for cropland, CRP land, and pastureland. Erosion prediction models for rangeland are currently under development and evaluation. Developed Land: The NRI category of developed land differs from that used by some other data collection entities. For the NRI, the intent is to identify which lands have been removed from the rural land base, while other studies are interested in human populations (e.g., Census of Population) and housing units (e.g., American Housing Survey). The NRI developed land category includes (a) large tracts of urban and built-up land; (b) small tracts of built-up land of less than 10 acres; and (c) land outside of these built-up areas that is


6

in a rural transportation corridor (roads, railroads, and associated rights-of-way). CRP Land: For the NRI, CRP land is classified separately from cropland because it provides different resource and conservation issues than hayland, horticultural cropland, and cultivated cropland. Acres in CRP can be added to NRI cropland acres for analyses and reporting. The CRP land use in the NRI is only the CRP general sign-up and does not include CRP continuous sign-ups. See the definitions for the distinctions. CRP acreage in this report will differ slightly from the administrative reports produced by the Farm Service Agency due to weighting issues at the state level. Irrigation: For the NRI, land is considered irrigated if irrigation occurs during the year of inventory, or during 2 or more of the 4 years prior to the inventory. Other entities typically consider land to be irrigated only if irrigation water is applied for the year of interest. Wetlands: NRI classification of wetlands is slightly different than that used by the Fish & Wildlife Service (FWS) in their statistically based Wetlands Status and Trends study. The NRI and the FWS inventory have different legislative mandates; sampling methodology, inventory protocols, data handling, and analysis routines have evolved independently over the past two decades, even though both survey programs use the hierarchical Cowardin classification system. Recent collaborative efforts have resulted in enhanced classifications for both programs, but wetlands data collected by the two agencies are currently neither comparable nor interchangeable. The NRI multi-resource approach is beneficial to USDA analysts and others who examine conservation and agri-environmental issues. Results from the FWS study are beneficial to analysts in the Department of the Interior and others. Availability of the Data

Overview of Survey Findings

• The contiguous 48 states, Hawaii, Puerto Rico, and the U.S. Virgin Islands cover almost 1.95 billion acres of land and water; about 71 percent of this area is non-Federal rural land – nearly 1.4 billion acres.

• Non-Federal rural lands are predominantly rangeland (409 million acres), forest land (409 million acres), and cropland (361 million acres).

• Cropland. Cropland acreage increased by about 2

million acres from 2007 to 2010 after a steady decline over the previous 25 years. The increase was a little over 0.5 percent from 359 to 361 million acres. Most of the gain came from land coming out of the Conservation Reserve Program counterbalanced to some degree by losses of cropland to pasture, development, and other rural land. (See Cropland Gains and Losses charts below.)

• Conservation Reserve Program (CRP). Between 2007 and 2010, the acreage of land in the CRP was reduced by nearly 18 percent, from 32.3 to 26.6 million acres. About half of that acreage became cropland, while another third became pastureland. (See CRP Gains and Losses charts below.)

• Erosion. Soil erosion on cropland decreased 41 percent between 1982 and 2010. Water (sheet and rill) erosion declined from 1.67 billion tons per year to 982 million tons per year, and erosion due to wind decreased from 1.38 billion to 740 million tons per year. The estimate of the change in erosion from 2007 to 2010 was not statistically significant from zero. (See chart below and map on page 11.)

• Prime Farmland. About 23 percent (or 316

million acres) of the non-Federal rural land base is classified as prime farmland. This represents a loss of over 13 million acres since 1982; most of this loss was due to development.


8

• Development. About 43 million acres of land were newly developed between 1982 and 2010, bringing the total to about 113 million acres; that represents a 58 percent increase. Thus, more than 37 percent of developed land in the 48 conterminous states, Hawaii, Puerto Rico and the U.S. Virgin Islands was developed during the last 28 years. From 2007 to 2010 developed land increased 2.1 percent. In addition, every one of the 48 conterminous states, Hawaii, and the Caribbean had statistically significant increases in developed land.

• Wetlands. Palustrine and Estuarine wetlands

covered 7.2 percent of the water and non-Federal lands in the 48 conterminous states, Hawaii, Puerto Rico, and the Virgin Islands, with over half being in forest lands.

Terms in italics within a definition refer to terms defined elsewhere in this Glossary. An expanded (complete) NRI Glossary is available at http://www.nrcs.usda.gov/wps/portal/nrcs/detail/national/technical/nra/nri/?cid=nrcs143_014127. Barren Land. A land cover/use category used to classify lands with limited capacity to support life and having less than 5 percent vegetative cover. Vegetation, if present, is widely spaced. Typically, the surface of barren land is sand, rock, exposed subsoil, or salt-affected soils. Subcategories include salt flats; sand dunes; mud flats; beaches; bare exposed rock; quarries, strip mines, gravel pits, and borrow pits; riverwash; oil wasteland; mixed barren lands; and other barren land. Built-up land. See urban and built-up areas. C factor (USLE). See cover and management factor. C factor (WEQ). See climatic factor. Climatic factor (C factor - WEQ). Characterizes climatic erosivity, specifically wind speed and surface soil moisture. The factor for any given locality is expressed as a percentage of the C factor for Garden City, Kansas, which has a value of 100. Conservation practice. A specific treatment, such as a structural or vegetative measure or management technique commonly used to meet specific needs in planning and conservation, for which standards and specifications have been developed. Conservation practices are in the NRCS Field Office Technical Guide, Section IV, which is based on the National Handbook of Conservation Practices. (The practices recorded for NRI have been applied to the area of land in which the NRI point falls or the portion of the field that would be used in conservation planning. The point need not fall on a specific practice.) Conservation Reserve Program (CRP). 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. CRP continuous sign-up. Continuous CRP was introduced in the 1996 Farm Bill. Eligible lands must

be suitable to serve as one of a number of conservation practices, such as a wetland restoration, filterstrip, riparian buffer, or field windbreak. Landowners and operators with eligible lands may enroll the high priority conservation practices at any time during the year without competition. For NRI, land enrolled in the continuous CRP is included in its respective land cover/use (i.e: cropland, grassland, forest, marsh, etc.). CRP general sign-up. General CRP was introduced in the 1985 Farm Bill. Eligible lands must be highly erodible or in a State or National conservation priority area. Landowners and operators with eligible lands compete nationally for acceptance based on an environmental benefits index (EBI) during specified enrollment periods. CRP land use. For NRI, only acres that have been enrolled in CRP general sign-up are included in the CRP land cover/use category. It does not include acres enrolled under CRP continuous sign-up. Cover and management factor (C factor - USLE). The ratio of soil loss from an area with specific cover and management to that from an identical area in tilled continuous fallow. Cowardin system. A classification system of wetlands and deepwater habitats of the United States, officially adopted by the U.S. Fish and Wildlife Service (FWS) used to develop wetland data bases. The five major systems are Estuarine, Lacustrine, Marine, Palustrine, and Riverine (Cowardin, et.al., 1979). Cropland. A land cover/use category that includes areas used for the production of adapted crops for harvest. Two subcategories of cropland are recognized: cultivated and noncultivated. Cultivated cropland comprises land in row crops or close-grown crops and also other cultivated cropland, for example, hayland or pastureland that is in a rotation with row or close-grown crops. Noncultivated cropland includes permanent hayland and horticultural cropland. Cultivated cropland. See cropland. Deepwater habitat. Any open water area in which the mean water depth exceeds 6.6 feet in nontidal areas or at mean low water in freshwater tidal areas, or is covered by water during extreme low water at spring

tides in salt and brackish tidal areas, or covers the deepest emerging vegetation, whichever is deeper. Developed land. A combination of land cover/use categories, large urban and built-up areas, small built-up areas, and rural transportation land. Erosion. The wearing away of the land surface by running water, waves, or moving ice and wind, or by such processes as mass wasting and corrosion (solution and other chemical processes). The term "geologic erosion" refers to natural erosion processes occurring over long (geologic) time spans. "Accelerated erosion" generically refers to erosion that exceeds what is presumed or estimated to be naturally occurring levels, and which is a direct result of human activities (e.g., cultivation and logging). Estuarine Wetland. Wetlands occurring in the Estuarine System, one of five systems in the classification of wetlands and deepwater habitats (Cowardin et al., 1979). Estuarine wetlands are tidal wetlands that are usually semi-enclosed by land but have open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The most common example is where a river flows into the ocean. Farmsteads and ranch headquarters. A land cover/use category that includes dwellings, outbuildings, barns, pens, corrals and feedlots next to buildings, farmstead or feedlot windbreaks, and family gardens associated with operating farms and ranches. (Commercial feedlots, greenhouses, poultry facilities, overnight pastures for livestock, and field windbreaks are not considered part of farmsteads.) Federal land. See Ownership. Field. A cultivated area of land that is marked out for a particular crop or cropping sequence. Forest land. A land cover/use category that is at least 10 percent stocked by single-stemmed woody species of any size that will be at least 4 meters (13 feet) tall at maturity. Also included is land bearing evidence of natural regeneration of tree cover (cut over forest or abandoned farmland) and not currently developed for non-forest use. Ten percent stocked, when viewed from a vertical direction, equates to an areal canopy cover of leaves and branches of 25 percent or greater. The

minimum area for classification as forest land is 1 acre, and the area must be at least 100 feet wide. Growing season. The period and/or number of days between the last freeze in the spring and the first frost in the fall for the freeze threshold temperature of the crop or other designated temperature threshold. Hayland. A subcategory of cropland managed for the production of forage crops that are machine harvested. The crop may be grasses, legumes, or a combination of both. Hayland also includes land in set-aside or other short-term agricultural programs. Horticultural cropland. A subcategory of cropland used for growing fruit, nut, berry, vineyard, and other bush fruit and similar crops. Nurseries and other ornamental plantings are included. I factor (WEQ). See soil erodibility index. Irrigated land. Land that shows evidence of being irrigated during the year of the inventory or of having been irrigated during 2 or more of the last 4 years. Water is supplied to crops by ditches, pipes, or other conduits. For the purposes of the NRI, water spreading is not considered irrigation. K factor (USLE). See soil erodibility factor (USLE). K factor (WEQ). See ridge roughness factor (WEQ). L factor (USLE). See slope-length factor (USLE). L factor (WEQ). See unsheltered distance factor (WEQ). Lacustrine System. Wetlands and deepwater habitats occurring in the Lacustrine System, one of five systems in the classification of wetlands and deepwater habitats (Cowardin et al., 1979). The Lacustrine System includes wetlands and deepwater habitats with all of the following characteristics: (1) situated in a topographic depression or a dammed river channel; (2) lacking trees, shrubs, persistent emergent plants, emergent mosses or lichens with greater than 30% areal coverage; and (3) total area exceeding 20 acres. Similar habitats totaling less than 20 acres are included if an active wave-formed or bedrock shoreline feature makes up all or part of the boundary, or if the water depth in the deepest part of the basin exceeds 6.6 feet at low water.

Land capability classification (class and subclass). Land capability classification is a system of grouping soils primarily on the basis of their capability to produce common cultivated crops and pasture plants without deteriorating over a long period. Land capability classification is subdivided into capability class and capability subclass nationally.

Capability class. The broadest category in the system. Class codes I to VIII indicate progressively greater limitations and narrower choices for agriculture. The numbers are used to represent both irrigated and nonirrigated land capability. Capability subclass. The second category in the system. Class codes e (erosion problems), w (wetness problems), s (root zone limitations), and c (climatic limitations) are used for land capability subclasses.

Land cover/use. A term that includes categories of land cover and categories of land use. 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. Large urban and built-up areas. A land cover/use category composed of developed tracts of at least 10 acres—meeting the definition of urban and built-up areas. Margins of Error. Margins of error are reported for each NRI estimate. The margin of error is used to construct the 95 percent confidence interval for the estimate. The lower bound of the interval is obtained by subtracting the margin of error from the estimate; the upper bound is obtained by adding the margin of error to the estimate. Confidence intervals can be created for various levels of significance which is a measure of how certain we are that the interval contains the true value we are estimating. A 95 percent confidence interval means that in repeated samples from the same population, 95 percent of the time the true underlying population parameter will be contained within the lower and upper bounds of the interval. Marine System. The open ocean overlying the continental shelf and its associated high energy coastline. Marine habitats are exposed to the waves and

currents of the open ocean and the water regimes are determined primarily by the ebb and flow of oceanic tides. One of the five systems in the classification of wetlands and deepwater habitats. (Cowardin et al., 1979.) Marshland. A subcategory of the land cover/use category other rural land, described as a non-forested area of land partly or intermittently covered with water and usually characterized by the presence of such monocotyledons as sedges and rushes. These areas are usually in a wetland class and are not placed in another NRI land cover/use category, such as rangeland or pastureland. Noncultivated cropland. See cropland. Other aquatic habitats. Includes wetlands and deepwater habitats occurring in the Riverine, Lacustrine, or Marine Systems, and deepwater habitats occurring in the Estuarine System as defined by Cowardin et al. 1979 (see Wetlands). Other rural land. A land cover/use category that includes farmsteads and other farm structures, field windbreaks, barren land, and marshland. Ownership. The separation of Federal and non-Federal lands and the distinction between administrative units of land. Water areas are not classified according to ownership. The six categories of ownership are:

Private. A type of ownership pertaining to land belonging to an individual person or persons, a partnership, or a corporation (all of which are persons in the legal sense), as opposed to the public or the government; private property. Municipal. A type of ownership pertaining to land belonging to the local government of a town or city. County or parish. A type of ownership pertaining to land belonging to an administrative subdivision of a State in the United States, which is identified as a county or an equivalent administrative unit in areas where counties do not exist; examples are parishes in Louisiana and boroughs in Alaska.

Summary Report


15

State. A type of ownership pertaining to land belonging to one of the States, commonwealths, or territories of the United States of America. Federal land. A land ownership category designating land that is owned by the Federal Government. It does not include, for example, trust lands administered by the Bureau of Indian Affairs or Tennessee Valley Authority (TVA) land. No data are collected for any year that land is in this ownership. Indian tribal and individual Indian trust lands. A type of ownership of land administered by officially constituted Indian tribal or individual Indian trust entities.

P factor. See Practice factor. Palustrine Wetland. Wetlands occurring in the Palustrine System, one of five systems in the classification of wetlands and deepwater habitats (Cowardin et al., 1979). Palustrine wetlands include all nontidal wetlands dominated by trees, shrubs, persistent emergent plants, or emergent mosses or lichens, as well as small, shallow open water ponds or potholes. Palustrine wetlands are often called swamps, marshes, potholes, bogs, or fens. Pastureland. A land cover/use category of land managed primarily for the production of introduced forage plants for livestock grazing. Pastureland cover may consist of a single species in a pure stand, a grass mixture, or a grass-legume mixture. Management usually consists of cultural treatments: fertilization, weed control, reseeding or renovation, and control of grazing. For the NRI, includes land that has a vegetative cover of grasses, legumes, and/or forbs, regardless of whether or not it is being grazed by livestock. Photographic interpretation. The act of examining photography images for the purpose of identifying objects and judging their significance. Practice factor (P factor - USLE). The ratio of soil loss with a support practice like contouring, stripcropping, or terracing, to soil loss with straight-row farming up and down the slope.

Prime farmland. Land that 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. Railroads. A category of rural transportation areas that includes all operational rail systems and their rights-of-way. Abandoned railroad beds are not included as railroad areas. Rainfall and runoff (R factor - USLE). The number of rainfall erosion index units, plus a factor for runoff from snowmelt or applied water where such runoff is significant. Rangeland. A land cover/use category on which the climax or potential plant cover is composed principally of native grasses, grasslike plants, forbs or shrubs suitable for grazing and browsing, and introduced forage species that are managed like rangeland. This would include areas where introduced hardy and persistent grasses, such as crested wheatgrass, are planted and such practices as deferred grazing, burning, chaining, and rotational grazing are used, with little or no chemicals or fertilizer being applied. Grasslands, savannas, many wetlands, some deserts, and tundra are considered to be rangeland. Certain communities of low forbs and shrubs, such as mesquite, chaparral, mountain shrub, and pinyon-juniper, are also included as rangeland. Remote sensing. The science and art of obtaining information about an object, area, or phenomenon through the analysis of data acquired by a device that is not in contact with the object, area, or phenomenon under investigation. Ridge roughness (K factor - WEQ). A measure of the effect of ridges made by tillage and planting implements. It is expressed as a decimal from 0.5 to 1.0. Ridges, especially those at right angles to the prevailing wind direction, absorb and deflect wind energy and trap moving soil particles. See wind erosion equation (WEQ). Riverine System. All wetland and deepwater habitats contained within a channel, with two exceptions (1) wetlands dominated by trees, shrubs, persistent emergents, emergent mosses, or lichens; and (2) habitats with water containing ocean derived salts. One of the five systems in the classification of wetlands and deepwater habitats. (Cowardin et al., 1979.)

Row crops. A subset of the land cover/use category cropland (subcategory, cultivated) comprising land in row crops, such as corn, soybeans, peanuts, potatoes, sorghum, sugar beets, sunflowers, tobacco, vegetables, and cotton. Rural transportation land. A land cover/use category which consists of all highways, roads, railroads and associated right-of-ways outside urban and built-up areas; also includes private roads to farmsteads or ranch headquarters, logging roads, and other private roads (field lanes are not included). S factor. See slope-steepness factor. Sample point. The second-stage sample unit in the NRI two-stage sampling scheme. See also Segment. Segment. An area of land, typically square to rectangular in shape, that is approximately 40, 100, 160, or 640 acres in size. Within the segment, sample points are assigned. Certain data elements are collected for the entire segment, while others are collected at the segment points. Sheet and rill erosion. The removal of layers of soil from the land surface by the action of rainfall and runoff. It is the first stage in water erosion. Slope. The inclination of the soil surface from the horizontal. Slope percent is the vertical distance divided by the horizontal distance, then multiplied by 100. Slope length. The distance from the point of origin of overland flow to the point where either the slope gradient decreases enough that deposition begins, or the runoff water enters a well-defined channel that may be part of a drainage network or a constructed channel. For the NRI, length of slope is taken through the sample point. Slope-length factor (L factor - USLE). The ratio of soil loss from the field slope length to that from a 72.6-foot length under identical conditions. Slope-steepness factor (S factor - USLE). The ratio of soil loss from the field slope gradient to that from a 9 percent slope under otherwise identical conditions. Used in universal soil loss equation (USLE) calculations of sheet and rill erosion.

Small built-up areas. A land cover/use category consisting of developed land units of 0.25 to 10 acres, which meet the definition of urban and built-up areas. Soil erodibility factor (K factor - USLE). An erodibility factor which quantifies the susceptibility of soil particles to detachment and movement by water. This factor is used in the universal soil loss equation (USLE) to calculate soil loss by water. Soil erodibility index (I factor - WEQ). The potential soil loss, in tons per acre per year, from a wide, level, unsheltered, isolated field with a bare, smooth, loose, and noncrusted surface, under climatic conditions like those in the vicinity of Garden City, Kansas. Soil loss tolerance factor (T factor - USLE). The maximum rate of annual soil loss that will permit crop productivity to be sustained economically and indefinitely on a given soil. Soil survey. The systematic examination, description, classification, and mapping of soils in an area. The USDA- NRCS Soil Survey Program produces Soil Survey Reports, which generally consist of four principal parts: (1) maps, (2) a map legend, (3) a description of the soils in the survey area, and (4) a use and management report. The survey area commonly is a single county but may comprise parts of counties, physiographic regions, or other management areas. Stream. A flow of water in a channel or bed, as a brook, rivulet, or small river. T factor (USLE). See soil loss tolerance factor. Universal soil loss equation (USLE). An erosion model designed to predict the long-term average soil losses in runoff from specific field areas in specified cropping and management systems. The equation is: A = RKLSCP

where A = Computed soil loss per unit area R = Rainfall and runoff factor K = Soil erodibility factor L = Slope-length factor S = Slope-steepness factor C = Cover and management factor P = Support practice factor

The NRI calculations use location-specific data for the field in which the NRI sample point falls or that portion of the field surrounding the point that would be considered in conservation planning.

Unsheltered distance (L factor - WEQ). The unsheltered distance along the prevailing wind erosion direction across the field or area to be evaluated. For the NRI, the unsheltered distance is expressed in feet, measured through the sample point, parallel to the prevailing wind direction during the critical wind erosion period. Uplands. All land not classified as wetland or deepwater habitat (Cowardin et al., 1979). Urban and built-up areas. A land cover/use category consisting of residential, industrial, commercial, and institutional land; construction sites; public administrative sites; railroad yards; cemeteries; airports; golf courses; sanitary landfills; sewage treatment plants; water control structures and spillways; other land used for such purposes; small parks (less than 10 acres) within urban and built-up areas; and highways, railroads, and other transportation facilities if they are surrounded by urban areas. Also included are tracts of less than 10 acres that do not meet the above definition but are completely surrounded by Urban and built-up land. Two size categories are recognized in the NRI: areas of 0.25 acre to 10 acres, and areas of at least 10 acres. V factor. See Vegetative cover. Vegetative cover (V factor - WEQ). The effect of vegetative cover in the wind erosion equation is expressed by relating the kind, amount, and orientation of vegetative material to its equivalent in pounds per acre of small grain residue in reference condition (small grain equivalent). Water areas. A land cover/use category comprising water bodies and streams that are permanent open water. Water body. A type of (permanent open) water area that includes ponds, lakes, reservoirs, bays or gulfs, and estuaries. Water spreading. Diverting or collecting runoff from natural channels, gullies, or streams with a system of dams, dikes, ditches, or other means, and spreading it over a relatively flat area. (See irrigated land.) Wetlands. Lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow

water. For purposes of this classification wetlands must have one or more of the following three attributes: (1) at least periodically, the land supports predominantly hydrophytes; (2) the substrate is predominantly undrained hydric soil; and (3) the substrate is nonsoil and is saturated with water or covered by shallow water at some time during the growing season of each year. (Cowardin, et.al., 1979). Wetland losses. Wetland losses are described in terms of gross and net. Net change is defined as the gross gain minus the gross loss, and can be either positive (net gain) or negative (net loss) for a given region. Wetland losses were attributed to one of the following categories:

a. Development. Loss occurring on land cover/use category of urban and built-up or rural transportation.

b. Agriculture. Loss occurring on land cover/use category of cropland, pastureland, CRP land, farmsteads or other farmland.

c. Silviculture. Loss occurring on forest land. d. Miscellaneous. Loss occurring on all other

land cover/use categories including mined land, rangeland, and other barren lands. Natural variations in climatic cycles and hydrology are responsible for the majority of these losses.

Wind erosion. The process of detachment, transport, and deposition of soil by wind. Wind erosion equation (WEQ). An erosion model designed to predict long-term average annual soil losses from a field having specific characteristics. The equation is: E = f(IKCLV)

where E = Estimated average annual soil loss expressed in tons per acre per year I = Soil erodibility index K = Soil ridge roughness factor C = Climatic factor L = Equivalent unsheltered distance across the field along the prevailing wind erosion direction V = Equivalent vegetative cover

Explanation of the Tables

On the following pages selected national summary data are displayed in 26 tables. Definitions of terms are the same as for previous NRIs (see Glossary of Terms above). National totals include results for the 48 conterminous States, Hawaii, and the Caribbean area. Table 1 presents NRI findings on surface area: Federal land, non-Federal rural land, non-Federal developed land, and water areas. Table 2 presents estimates of acreage in six land cover/use components of non-Federal rural land: cropland, land enrolled in the Conservation Reserve Program (CRP), pastureland, rangeland, forest land, and other rural land. Tables 3 through 9 provide, respectively, an overview of land use changes from 1982 to 1987, 1987 to 1992, 1992 to 1997, 1997 to 2002, 2002 to 2007, 2007 to 2010, and 1982 to 2010. These tables show all land conversions, whereas tables 1, 2, 10, 11, and 12 present net land use change. Table 10 shows estimates of cropland classified as irrigated or nonirrigated, cultivated or noncultivated. Table 11 presents acres of land cover/use by land capability class and subclass. See “Land capability classification” in the glossary for more details on this system. Table 12 presents the distribution of prime farmland by land cover/use. Prime farmland is land that 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. Tables 13 and 14 present estimates of soil erosion rates on cultivated cropland, noncultivated cropland, CRP land, and pastureland. Table 13 shows estimates of rates of sheet and rill erosion, which is erosion caused by water; table 14 presents estimates of wind erosion rates. Tables 15 and 16 present estimates of acreages of cropland (cultivated and noncultivated), CRP land, and pastureland that have erosion rates greater than the soil loss tolerance rate (“T”). The soil loss tolerance rate is the rate at which the soil can withstand erosion without inherent loss of productivity. Table 17 shows State-by-State estimates of the extent of Palustrine and Estuarine wetlands and other aquatic habitats on water areas and non-Federal land. Table 18 presents State-by-State estimates of Palustrine and Estuarine wetlands on water areas and non-Federal land according to land cover/use type. Tables 19 through 22 present estimates of changes in acreages in wetland and deepwater habitats from 1992 to 1997, 1997 to 2002, 2002 to 2007, and 2007 to 2010, respectively. Table 23 presents conservation practices by land cover/use and year. Table 24 presents acreage on cropland and pastureland by specific land cover/use and year.

Notes: • Acreages for Conservation Reserve Program (CRP) land are established through geospatial processes and administrative records; therefore, statistical margins of error are not applicable and shown as a dashed line (--). CRP was not implemented until 1985. • Cropland includes cultivated and non-cultivated cropland. • When the estimate is 0.0, margins of error are not applicable and shown as a dashed line (--). • Estimates in red = STOP, these estimates are not reliable. The margin of error is equal to or greater than the estimate so the confidence interval includes zero.

Notes: • CRP was not implemented until 1985. • Cropland includes cultivated and non-cultivated cropland. • When the estimate is 0.0, margins of error are not applicable and shown as a dashed line (--). • Estimates in red = STOP, these estimates are not reliable. The margin of error is equal to or greater than the estimate so the confidence interval includes zero.

Notes: • CRP was not implemented until 1985. • Cropland includes cultivated and non-cultivated cropland. • When the estimate is 0.0, margins of error are not applicable and shown as a dashed line (--). • Estimates in red = STOP, these estimates are not reliable. The margin of error is equal to or greater than the estimate so the confidence interval includes zero.

Notes: • Conservation Reserve Program (CRP) land was not implemented until 1985. • Estimates and estimated margins of error <.01 are shown as 0.00. • When the estimate is 0.0, margins of error are not applicable and shown as a dashed line (--). • Estimates in red = STOP, these estimates are not reliable. The margin of error is equal to or greater than the estimate so the confidence interval includes zero.

State Year Cropland


Notes: • Conservation Reserve Program (CRP) land was not implemented until 1985. • Estimates and estimated margins of error <.01 are shown as 0.00. • When the estimate is 0.0, margins of error are not applicable and shown as a dashed line (--). • Estimates in red = STOP, these estimates are not reliable. The margin of error is equal to or greater than the estimate so the confidence interval includes zero.

Notes: • Acreages for Conservation Reserve Program (CRP) land are established through geospatial processes and administrative records; therefore, statistical margins of error are not applicable and shown as a dashed line (--). CRP was not implemented until 1985. • Cropland includes cultivated and non-cultivated cropland. • Estimates in red = STOP, these estimates are not reliable. The margin of error is equal to or greater than the estimate so the confidence interval includes zero.

Notes: • Acreages for Conservation Reserve Program (CRP) land are established through geospatial processes and administrative records; therefore, statistical margins of error are not applicable and shown as a dashed line (--). CRP was not implemented until 1985. • Cropland includes cultivated and non-cultivated cropland. • Estimates in red = STOP, these estimates are not reliable. The margin of error is equal to or greater than the estimate so the confidence interval includes zero.
