Revised Inventory Results
This bulletin presents revised summary results from the
1997 National Resources Inventory (NRI). The NRI is
conducted by the U.S. Department of Agriculture’s
Natural Resources Conservation Service, in cooperation
with the Iowa State University Statistical Laboratory.
This bulletin has been reissued because in March 2000
an error was discovered in the 1997 NRI results originally
issued in December 1999. The error was in the statistical
software used by the Statistical Laboratory to calculate
estimates for the inventory. Re-release of the inventory
results was delayed until December 2000 in order to
conduct a complete quality assurance review of all phases
of the inventory, to institute a number of additional
quality checks, and to include wetlands data in the final
release.
The most noticeable difference between the data
released in December 1999 and the corrected estimates
issued in December 2000 is in the estimated increase in
developed lands. The corrected data show an increase of
11.2 million acres during the period 1992 to 1997; this
figure is 30% lower than the December 1999 estimate.
The corrected estimate of total developed land for 1997 is
98.3 million acres, which is 7.1 million acres lower than
the December 1999 estimate. This means the revised
figures show an additional 7.1 million acres of rural land
for 1997 and, subsequently, more acres of cropland,
rangeland, and forest land than were reported in
December 1999.
The computer programming error occurred in a
portion of the statistical estimation procedure that assigns
weights to sample points. These weights are based on
sampling (selection) probabilities, estimates from
previous NRIs, and known land base attributes from the
Census Bureau and other sources. Because of the
programming error, incorrect weights were assigned to
some sample points. Sample points that changed into
developed land were affected in a systematic manner (not
randomly), so that the corrections lowered all estimates of
1997 developed land.
Introduction
This bulletin includes state and national level estimates
for changes in broad land cover/use, cropland use by
irrigated and nonirrigated acres, broad land cover/use by
land capability class and subclass, prime farmland,
erosion and erodibility, wildlife habitat diversity, and
wetlands and deepwater habitats. These basic summary
statistics are presented via the Internet and in hard copy to
provide base-line natural resource information to a variety
of groups and individuals interested in obtaining insight
into the condition of our Nation's nonfederal rural lands.
Subsequent sections of this bulletin discuss the broader
suite of information available from the 1997 NRI and
methods for obtaining access to other results.
The NRI is a scientifically based, longitudinal panel
survey of the Nation’s soil, water, and related resources,
designed to assess conditions and trends every five years.
The 1997 NRI provides results that are nationally
consistent for all nonfederal lands for four points in time
1982, 1987, 1992, and 1997.
Background
The Natural Resources Conservation Service, formerly
the Soil Conservation Service, was established in
response to the Dust Bowl catastrophe of the mid-1930’s.
Hugh Hammond Bennett, the agency founder and first
administrator, convinced the U. S. Congress that soil
erosion was a national menace and that a permanent
agency within the Department of Agriculture was needed
to call landowners’ attention to their land stewardship
opportunities and responsibilities. The results of the 1934
National Erosion Reconnaissance Survey, which was the
first formal study of erosion conducted in the United
States, were instrumental in the passage of the Soil
Conservation Act of 1935. Through the Act, the Soil
Conservation Service was established, and a nationwide
partnership of federal agencies, local conservation
districts, and communities was developed to provide
assistance to the rural and urban sectors in the
conservation of natural resources. Today, more than 60
years later, NRCS champions the vitality of the land as

USDA’s lead conservation agency. No other federal
agency speaks for the health of America’s private land.
Throughout its history, NRCS has conducted periodic
inventories of the Nation’s natural resources. The 1945
Soil and Water Conservation Needs Inventory (CNI), a
reconnaissance study, was the foundation for the 1958
and 1967 CNI’s, 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. National
Resources Inventories were conducted in 1977, 1982,
1987, 1992, and 1997. Several less intensive, special-
issue inventories have been performed during the 1990’s
to investigate topical matters of concern and to
supplement recent NRIs.
In addition to these recurrent NRI inventories, NRCS
also collects large quantities of field level natural
resources data in support of conservation planning
activities and the Soil Survey Program. Thousands of
NRCS technical specialists, including soil scientists, soil
conservationists, range conservationists, foresters,
wildlife biologists, and agronomists, collect data at the
field and farm level in order to provide conservation
assistance to farmers and ranchers in the development of
conservation systems uniquely tailored to the land and
their individual way of doing business. Assistance is also
provided to rural and urban communities to help reduce
erosion, conserve and protect water resources, and solve
other resource-related problems. The information that
NRCS collects about natural resources in the United
States is critical for sustaining agriculture, promoting the
conservation and stewardship ethic, and preserving the
health of the Nation's natural resources and environment.
Legislation also has mandated that NRCS collect
natural resources data. The Rural Development Act of
1972 was a key statute in authorizing resource inventory
activities within NRCS. It directs 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 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 was developed to provide critical
information regarding natural resources and to
supplement the NRCS Soil Survey Program.
Inventory ProcedureThe objectives of NRCS resource inventories have
expanded over time, as the focus of agricultural policy has
moved toward a balance between short-term production
goals, long-term capabilities, and environmental quality.
Statistical techniques, data collection protocols, and data
handling and dissemination technologies have evolved as
inventory goals have become broader and more
sophisticated.
The primary objective of the 1997 NRI was to provide
natural resource managers, policy makers, and the public
with scientifically valid, timely, and relevant information
on natural resources and the environment. This
information can provide the scientific basis for effective
public policies, sound agricultural and natural resource
legislation, sensible state and national conservation
programs, and targeted USDA financial and technical
assistance in addressing natural resource concerns. 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 1996 Farm Bill.
To accomplish these objectives in a cost-effective
manner, it was necessary to conduct the 1997 NRI in
much the same manner as the 1992 NRI. Careful
consideration was given to assure that 1997 NRI data
elements were consistent with definitions, categories, and
concepts from previous inventories. The same sample
used for the 1992 NRI was used for 1997 data collection.
This enables analysis of trends extending over 15 years
(1982, 1987, 1992, and 1997).
NRI data are collected at scientifically selected sample
sites. The sample constitutes a two-stage stratified area

sample of the entire country. Samples are located in all
counties and parishes of the 50 states and in Puerto Rico,
the Virgin Islands, the District of Columbia, and selected
portions of the Pacific Basin. The first-stage sampling
unit, or primary sampling unit (PSU), is an area/segment
of land; the second-stage sampling units are points located
within the PSUs. Detailed NRI data are collected for the
specific sample points, but some items are also collected
for the entire PSU/segment. Some data, such as total
surface area, federally owned land, and area in large water
bodies, are collected on a census basis external to the
sample survey. The NRI database accounts for and
represents the total area of the United States, but very
little information is given for points on federal lands.
Data for the 1997 NRI were collected for about
300,000 PSUs and 800,000 sample points, using photo-
interpretation and other remote sensing methods and
standards. Data gatherers utilized a variety of ancillary
materials; extensive use was made of USDA field office
records, information provided by local NRCS field
personnel, soil survey and wetland inventory maps and
reports, and tables and technical guides developed by
local field office staffs. The NRI is unique because of
established linkages to the NRCS Soil Survey Program.
NRCS expertise in identifying soil occurrences and
patterns, and utilizing this knowledge to provide technical
assistance in the development of conservation plans for
landowners is a primary agency function. The NRI data
gathering process relies heavily upon information
contained in the Soil Survey Database. Information about
specific properties and characteristics of the soil and
surrounding landscapes is utilized to develop NRI data
elements and interpretations. NRI data is a primary
source of information for evaluating the success of NRCS
soil conservation programs in reducing soil erosion.
Inventory procedures were developed to ensure that
data reflect 1997 growing season conditions, that
inventory results are nationally consistent, and that data
recorded for the years 1982, 1987, and 1992 are
consistent with the 1997 determination. Intricate quality
assurance procedures were developed to make sure that
year-to-year differences reflect actual changes in resource
conditions, rather than differences in the perspectives of
two different data collection specialists or changes in
technologies and protocols.
Data gathering for the 1997 NRI occurred from July
1997 through October 1998. This time frame took into
account that some aerial photography needed to be flown
during a time period that highlighted late growing season
conditions. Consequently, delivery of imagery to some
data collection sites did not occur until later in the data
collection cycle.
Field visits were not required for the 1997 NRI unless
available imagery and ancillary materials were not
suitable for making determinations for one or more data
elements. Field visits were also made for training
purposes and other facets of the quality assurance process.
All NRI sample sites were visited on-site for the 1982
NRI. Subsequent on-site visits of selected PSUs also
occurred in 1987, 1991, 1992, or 1995.
The computer-assisted survey information collection
methods developed for the 1997 NRI provided substantial
efficiencies in data gathering and data processing and
were important facets of the quality assurance process.
The system featured direct entry of data into hand-held
computers called personal digital assistants (PDAs),
modern information technology, a national database
server at the Iowa State University Statistical Laboratory,
and elaborate data checking protocols that featured review
and edit of data recorded during previous inventories.
Standards and protocols for the NRI were developed
nationally by NRCS, in collaboration with the Statistical
Laboratory. Oversight and management of data-gathering
activities were assigned to 21 units established during
1996 and 1997. These units, called Inventory Collection
and Coordination Sites (ICCS’s) were established
according to regional land use patterns and according to
state allocations of resources. Geographic boundaries of
ICCS organizations ranged from one state to all or
portions of several states. Some ICCS’s distributed data

collection staff among multiple office locations, while
others assembled staff at one central location.
Inventory methodology is evolving as part of an
ongoing effort to better assess soil conservation, natural
resource health, and other agri-environmental issues. The
NRI has been conducted as a longitudinal survey designed
to assess condition and trends of nonfederal lands every 5
years. Current initiatives include transitioning to a
continuous resource inventory process, developing a
multi-agency integrated inventory approach,
incorporating a wider variety of assessment tools for
resource health, and further development of geospatial
analysis and modeling capabilities to support policy
analysis and program implementation.

The NRI database contains millions of pieces of
information. It can serve as the foundation for inspection
and analysis of the condition of our Nation’s natural
resources. It indicates
how our Nation’s nonfederal lands are being used;
the condition of our natural resources;
how land use patterns have changed over time.
The NRI database has been constructed in a manner
that facilitates the inspection and analysis of these data.
Sophisticated statistical procedures developed
collaboratively with Iowa State University have been used
to provide a database that scientifically incorporates a
broad array of data into a format that is easy to use and
manipulate. Appendix 1 presents an overview of
statistical considerations and provides references that
contain further details.
The 1997 NRI database contains data for four points
in time (1982, 1987, 1992, and 1997) that are comparable
and consistent, and that reflect true trends. Reliable and
accurate temporal analysis is available from this data set.
Analytical capabilities are greatly enhanced because
NRCS’s extensive soil interpretations database is an
integral and easy-to-use part of the NRI database.
The NRI is conducted to obtain scientifically valid,
timely, and relevant data on natural resources and
environmental conditions, with the specific goal of
supporting agricultural and environmental policy
development and program implementation. 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 the public’s understanding of
natural resources and environmental issues. Information
derived from the NRI is used by natural resource
managers; policy makers and analysts; consultants; the
media; other federal agencies; state governments;
universities; environmental, commodity, and farm groups;
and the public.

The NRI database contains linkages to other
databases, in particular to the agency’s extensive soil
interpretations database. Linkages can be made to other
databases by using other themes, such as cover/use, forest
cover type, and spatial features. Analysis of NRI data in
conjunction with other data sources is encouraged;
nonetheless, differences in definitions, concepts, and data
collection protocols should be carefully examined. It is
worth repeating that the NRI includes very little data for
federal lands.
The 1997 NRI database has been designed for use in
detecting significant changes in resource conditions
relative to the years 1982, 1987, 1992, and 1997. All
comparisons for two points in time should be made using
Summary Report
1997 National Resources Inventory (revised December 2000)

the new 1997 NRI database. Comparisons made using
data published for the 1982, 1987, or 1992 NRI may
produce erroneous results, because of changes in
statistical estimation protocols, and because all data
collected prior to 1997 were simultaneously reviewed
(edited) as 1997 NRI data were collected. Note, for
example, that federal land area for 1992 has been adjusted
from 408 to 402 million acres, and that the estimate of
1992 nonfederal rangeland has changed from 399 to 407
million acres.
The NRI provides not only overall estimates of change
in resource conditions but also the dynamics of the
changes. For example, it is typically more informative to
examine gross losses and gains in cropland (rather than
just the net change from one year to another) and further
to determine why cropland was lost (e.g., to urban
development), how much had been prime farmland, and
“where” these losses are occurring. If new cropland is
gained, the question is whether this will cause additional
conservation and environmental concerns because the
new cropland is more erodible, or the soils are less
productive and require higher levels of fertilization, or the
land is sited in some other sensitive location.
The erosion data cannot be used to compute the actual
erosion occurring during a particular year. Erosion rates
are 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.
Note also that NRI estimates of sheet and rill erosion are
based upon the standard Universal Soil Loss Equation
(USLE) and not the revised USLE (RUSLE), and that
erosion estimates are made only for cropland, CRP land,
and pastureland.
The NRI category of “developed land” varies from
that used by some other data collection entities. For the
NRI, the intent is to identify which lands have been
permanently removed from the rural land base.
Therefore, the developed land category includes: (a)
large tracts of urban and built-up land; (b) small tracts of
built-up land, less than 10 acres in size; and (c) land
outside of these built-up areas that is in roads, railroads,
and associated rights-of-way.
The 1997 NRI shows only minor changes in land
under Conservation Reserve Program (CRP) contracts for
the time period 1992 to 1997, even though most original
CRP contracts expired in the mid-1990’s and there were
extensive sign-ups during that period. This is because the
1997 NRI reflects conditions as of the 1997 growing
season, and most actual on-the-ground changes in CRP
land did not occur until later in 1997 or until the 1998
growing season.
For the NRI, land is considered irrigated if irrigation
occurs during the year of inventory, or for two or more of
the last four years. Other entities typically consider land
to be irrigated only if irrigation water is applied for the
year of interest.
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. 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 quite beneficial to USDA analysts and others
who examine conservation and agri-environmental issues.
Results from the FWS study are quite beneficial to the
Department of Interior and others.
The NRI has been designed to facilitate geospatial
analysis. This not only enhances the analysis process, but
also makes it possible to use a map to present analytical
findings. Maps produced from NRI data depict only
patterns or trends within an area and do not provide an
estimate of conditions for any specific location on the
map.

Availability
This report presents selected NRI summary data at the
national level. Further information regarding the NRI and
additional data summaries can be obtained from the
national NRI Internet site at:
http://www.nhq.nrcs.usda.gov/NRI.
Additional data summaries from the NRI will be
released periodically as more comprehensive analyses are
performed. Of particular interest are detailed
compilations of data at the state level, which can be
accessed via this Internet site. Active links to individual
state Internet sites are available for obtaining specific
state-level NRI information.
Explanation of the Tables
On the following pages selected national summary data
are displayed in 19 tables. Definitions of terms are the
same as for the 1992 NRI (see Appendix 3 – Glossary of
Selected Terms). National totals include results for the 48
contiguous states, Hawaii, and the Caribbean area.
Results for Alaska and the Pacific Basin islands of Guam,
Rota, Tinian, and Saipan will be released at a later date.
The category “other rural land,” which occurs in many
of the tables, includes farmsteads and other farm
structures, field windbreaks, barren land such as salt flats
or exposed rock, and marshland.
The figures used in the tables are estimates, not
absolutes. They are based on data collected at sample
sites, not data taken from a complete census. Therefore,
sampling variation is present but generally small for state
and national totals. However, sampling variation may be
significant when using these totals to calculate 5- and 10-
year changes. Small changes may not be statistically
significant.
Table 1 presents NRI findings on surface area, federal
land, nonfederal rural land, developed land, and water
area. Since 1982, federal land increased by 2.7 million
acres, nonfederal rural land decreased by 28.9 million
acres, and developed land increased by 25.0 million acres.
Developed land totaled 98.3 million acres in 1997 (fig. 1).
Tables 2 and 3 present estimates of acreage of land
cover/use for six components of nonfederal rural land
(cropland, CRP land, pastureland, rangeland, forest land,
and other rural land). Cropland is classified as irrigated,
nonirrigated, cultivated, or noncultivated acreage.
Cropland acreage nationally decreased by 44.0 million
acres between 1982 and 1997. Rangeland decreased by
10.8 million acres and pastureland decreased by 12.0
million acres. Table 3 further reveals a shift in irrigated
agriculture from west to east across the country.
Table 4 presents acres of land cover/use by land
capability class and subclass. The land capability
classification system was originally developed by the Soil
Conservation Service and provides a quick, uniform, and
useful way to evaluate the potential of land for crop
production. Each capability class has several subclasses
to identify specific limitations on use:
e = erosion risk,
w = wetness,
s = shallowness or root zone problems, and
c = climatic limitations.
Class I soils have few limitations that restrict their use.
Class II soils have moderate limitations that reduce the
choice of plants or that require careful management.
Land identified as Class IIe, for example, would be
suitable for growing crops if adequate measures were
installed to reduce or prevent soil erosion.
Class III soils have severe limitations that reduce the
choice of plants, require special conservation practices, or
both. Class IV soils have very severe limitations that
NRI on the Internet

reduce the choice of plants, require very careful
management, or both.
Class V soils are not likely to erode but have other
limitations, impractical to remove, that limit their use
largely to pasture or range, woodland or wildlife. Class
VI soils have severe limitations that make them generally
unsuitable for cultivation and limit their use largely to
pasture, range, woodland, or wildlife. Class VII soils
have very severe limitations that make them generally
unsuitable for cultivation and limit their use largely to
pasture, range, woodland, or wildlife. Class VIII soils
and miscellaneous land types have limitations that
preclude their use for commercial crop production and
restrict their use for recreation, wildlife, water supply, or
esthetic purposes.
Tables 5, 6, 7, and 8 provide an overview of land use
changes from 1982−97, 1982−87, 1987−92, and 1992−97.
These tables show all land conversions, whereas previous
tables presented net land use change. For example, table
5 shows that a total of 70.7 million acres of 1982 cropland
was converted to other uses by 1997, which was offset by
26.7 million acres converted to cropland from non-
cropland uses since 1982. The net change was therefore a
reduction of 44.0 million acres of cropland, as shown in
table 2. Table 5 further shows that, of the 70.7 million
acres of cropland converted to other uses, 30.4 million
acres went to CRP, 19.3 million acres went to
pastureland, 3.7 million acres went to rangeland, 5.6
million acres went to forest land, 3.2 million acres went to
other rural land, 7.1 million acres went to developed land,
and 1.5 million acres went to water areas and federal land.
Of the 26.7 million acres converted to cropland from
other uses, 15.3 million acres came from pastureland, 7.0
million acres came from rangeland, 2.0 million acres
came from forest land, 1.4 million acres came from other
rural land, 0.2 million acres came from developed land,
and 0.8 million acres came from water areas and federal
land.
Table 9 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. There were 331.9 million
acres of prime farmland in 1997, which was down 10.0
million acres from 1982. Most (64%) of the prime
farmland is in cropland, but large amounts are in
pastureland (35.5 million acres) and forest land (48.7
million acres).
Tables 10 and 11 present estimates from the NRI for
soil erosion rates. Table 10 shows rates of sheet and rill
erosion, which is erosion caused by water; table 11
presents estimates of wind erosion. Average erosion rates
for 1997 are substantially lower than erosion rates for
1982. The average rate of sheet and rill erosion fell from
4.0 tons per acre per year in 1982 to 2.8 tons per acre per
year in 1997. The average rate of wind erosion on the
same land base fell from 3.3 tons per acre per year in
1982 to 2.2 tons per acre per year in 1997. The combined
wind and water erosion reduction translates to a savings
of more than 1.2 billion tons of soil per year on cropland
(fig. 2).
Tables 12 and 13 present acres of cropland (cultivated
and noncultivated), pastureland, and CRP land with
erosion rates greater than T, the soil loss tolerance or rate
at which soil productivity is maintained.
Table 14 shows acreage according to six classes of
erodibility index scores. The erodibility index (EI)
provides a numerical expression of the potential for a soil
to erode, considering the physical and chemical properties
of the soil and climatic conditions where it is located.
The higher the index, the greater the investment needed to
maintain the sustainability of the soil resource base if
intensively cropped. EI scores above 8 are equated to
highly erodible land.
Table 15 presents statistical information dealing with
wildlife habitat composition and configuration. Median
diameter of habitat patch size is an indicator of habitat
diversity. For the 1997 NRI, general cover data were
collected along X-shaped transects (the length of each
diagonal line of the transect was 1,000 feet). Patches of
cover were classified to one of nine general cover types
Summary Report

(see Appendix 3, glossary). Entries in Table 15 denoted
as “> 1,000” indicate that at least 50% of the transects
were classified as having a 1,000 foot length of the same
cover type.
Tables 16, 17, 18, and 19 present estimates of status
and changes in wetland and deepwater habitat acreage;
classification of these systems is according to the
Cowardin et al. (1979) classification system. Table 16
shows an estimate of 111.2 million acres of Palustrine and
Estuarine wetlands on water areas and nonfederal land for
1997, as well as an additional 47.8 million acres of other
aquatic habitats. Table 17 presents the distribution of
Palustrine and Estuarine wetlands by land cover/use; most
(59%) of these acres are on forest land. Table 18 shows
506.0 thousand acres of Palustrine and Estuarine wetlands
were converted to uplands between 1992 and 1997, and
343.2 acres of uplands were converted to Palustrine and
Estuarine wetlands during this time period (fig. 3). These
conversion estimates show an average annual gross loss
of 101.2 thousand acres, an average annual gross gain of
68.6 thousand acres, and an average annual net loss of
32.6 thousand acres per year. These figures do not take
into account any losses or gains occurring on federal land.
Table 19 presents more particulars regarding the losses
and gains. Development accounts for 49% of the losses;
agriculture accounts for 26 % of the losses (fig. 4).
Natural variations in climatic cycles and hydrology are
responsible for the majority of wetland losses captured in
the "miscellaneous causes" category. Estimates dealing
with losses and gains are presented nationally and by
region, but not by state; almost all state numbers are
smaller (in absolute value) than their margins of error and,
therefore, not significantly different (statistically) than
zero. Estimated margins of error (or 95% confidence
intervals) are presented in table 19 to assist the reader in
determining which regional estimates are statistically
significant. Margins or error and statistical reliability are
discussed in Appendix 1.
M e t r i c C o n v e r s i o n To convert acres to hectares, multiply the number of acres
by 0.405.
To convert tons to metric tons, multiply the number of
tons by 0.907.
To convert tons/acre to metric tons/hectare, multiply the
number of tons/acre by 2.24.
