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

Summary Report

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

Summary Report

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

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.
