Wilderness: Overview and Statistics
Summary
Congress enacted the Wilderness Act in 1964. This Act created the National
Wilderness Preservation System, reserved to Congress the authority to designate
wilderness areas, and directed the Secretaries of Agriculture and of the Interior to
review certain lands for their wilderness potential. The Act also designated 54
wilderness areas with 9 million acres of federal land. Congress began expanding the
Wilderness System in 1968, and today, there are 649 wilderness areas, totaling more
than 105 million acres, in 44 states. Numerous bills to designate additional areas and
to expand existing ones are introduced and considered in every Congress.
The Wilderness Act defined wilderness as an area of generally undisturbed
federal land, but did not establish criteria or standards to determine whether an area
should be designated, because of differing perceptions of wilderness and because of
the varying purposes of wilderness. In general, wilderness areas are undeveloped,
and commercial activities, motorized access, and roads, structures, and facilities are
prohibited in wilderness areas. However, in response to conflicting demands,
Congress has granted both general exemptions and specific exceptions to the general
standards and prohibitions.
The federal government owns about 29% of the land in the United States,
although the proportion in each state varies widely. Four federal agencies — the
Bureau of Land Management, National Park Service, and Fish and Wildlife Service
in the Department of the Interior and the Forest Service in the Department of
Agriculture — manage most of the federal lands. These agencies manage the 106
million acres of designated wilderness, as well as many other lands. In addition, they
have are protecting another 46 million acres as possible additions to the Wilderness
System, and are reviewing the wilderness potential of additional lands.
In total, more than 23% of all federal land, and nearly 7% of all land in the
United States, has been designated as wilderness or is being protected as possible
wilderness. Alaska, because of its size and relatively pristine condition, dominates
wilderness statistics — more than 54% of designated wilderness is in Alaska. In
total, nearly 16% of all land (federal, state, private, and other) in Alaska has been
designated as wilderness. In contrast, 4% of all land in the United States outside
Alaska has been designated as wilderness.
This report will be updated after the end of each Congress, to include changes
enacted.

Wilderness: Overview and Statistics
In 1964, the Wilderness Act established a national system of congressionally
designated areas to be preserved in a wilderness condition. The National Wilderness
Preservation System was created with 9 million acres of Forest Service lands.
Congress has since expanded the Wilderness System to more than 105 million acres
(see Table 1) among some 620 million acres of land managed by the federal land
management agencies — the Forest Service (FS) in the Department of Agriculture,
and the National Park Service (NPS), Fish and Wildlife Service (FWS), and Bureau
of Land Management (BLM) in the Department of the Interior. (See Table 2.)
Federal agencies, Members of Congress, and interest groups have recommended
more lands for inclusion in the System. Furthermore, at the direction of Congress,
agencies have studied, or are studying, the wilderness potential of their lands. This
report provides a brief history of wilderness, describes what wilderness is, identifies
permitted and prohibited uses in wilderness areas, and provides data on wilderness
designations and federal agency recommendations, as of December 31, 2004.
History of Wilderness
The federal government acquired 1.8 billion acres of land through purchases,
treaties, and other agreements. Initial federal policy was generally to transfer
ownership to states and private ownership, but Congress has also provided for
reserving certain lands for federal purposes, and over time has reserved or withdrawn
increasing acreage for national parks, national forests, wildlife refuges, etc.1 The
general policy of federal lands disposal was changed to a general policy of retaining
the remaining lands in the Federal Land Policy and Management Act of 1976.2
Beginning in 1897, management of the national forests emphasized conservation
— protecting and developing the lands. It did not take long for some FS leaders to
recognize the need to preserve some areas in a natural state. Acting at its own
discretion, the FS created the first wilderness area in the Gila National Forest (NM)
in 1924. In the succeeding decades, the agency’s system of wilderness, wild, and
primitive areas grew to 14.6 million acres. However, in the 1950s, increasing timber
harvests and recreation use of the national forests led to public concerns about the
permanence of this purely administrative system. The FS had relied on its
administrative authority in making these designations; there was no law guaranteeing
the future of wilderness.

In response to these concerns, Congress enacted the Wilderness Act3 in 1964.
The Act defines wilderness, and prohibits or restricts certain activities in wilderness
areas, while permitting other activities to occur. The Act also reserves to Congress
the authority to designate areas as part of the National Wilderness Preservation
System.
The Wilderness System was initially endowed with the 9.1 million acres of
national forest lands that had been identified administratively as wilderness areas or
wild areas. The Wilderness Act also directed the Agriculture Secretary to review the
agency’s 5.5 million acres of primitive areas, and the Secretary of the Interior to
evaluate the wilderness potential of National Park System and National Wildlife
Refuge System lands. The Secretaries were to report their recommendations to the
President and to Congress within 10 years (i.e., by 1974). Separate recommendations
were made for each area; many areas recommended for wilderness have been
designated, although some of the recommendations are still pending (and are
included in Table 3). FLPMA directed the Secretary of the Interior to conduct a
similar review of the public lands administered by the BLM within 15 years (i.e., by
1991). The BLM submitted its recommendations to the President, and presidential
recommendations have been submitted to Congress.
The 90th Congress began expanding the Wilderness System in 1968, as shown
in Table 1. Five laws were enacted, creating five new wilderness areas with 795,000
acres in four states. Wilderness designations generally increased in each succeeding
Congress, rising to a peak of 60.8 million acres designated during the 96th Congress
(1979-1980). The largest was 56.4 million acres of wilderness designated in the
Alaska National Interest Lands Conservation Act.4
In 1977, the FS began a review (RARE II5) of 62 million acres of national forest
roadless areas, as an acceleration of part of the land management planning process
mandated by the Forest and Rangeland Renewable Resources Planning Act of 1974
and the National Forest Management Act of 1976.6 The RARE II Final
Environmental Statement was issued in January 1979, recommending more than 15
million acres (24.3% of the study area) for addition to the Wilderness System.
Nearly 11 million acres (17.4%) were to be studied further in the ongoing FS
planning under process NFMA. The remaining 36 million acres (58.3% of the
RARE II area) were to be available for other uses — such as logging, energy and
mineral developments, and motorized recreation — which might be incompatible
with preserving wilderness characteristics. In April 1979, President Jimmy Carter
presented the recommendations to Congress with minor changes.

4 ANILCA, Act of Dec. 2, 1980; P.L. 96-487, 94 Stat. 2371.
5 The first Roadless Area Review and Evaluation (RARE) was begun under the agency’s
administrative authority in 1970, but was abandoned in 1972 because of a lawsuit asserting
the review had been restricted in ways that violated the National Environmental Policy Act
of 1969 (NEPA, Act of Jan. 1, 1970; P.L. 91-190, 83 Stat. 852; 42 U.S.C. §§4321-4347).

In 1980, the state of California successfully challenged the FS RARE II
recommendations for 44 areas allocated to nonwilderness uses, with the court
decision substantially upheld on appeal in 1982.7 The Reagan Administration
responded in 1983 by directing a re-evaluation of all RARE II recommendations,

language.8 Tensions between the Administration and Congress, and among interest

groups, led to a particularly intense debate during the 98th Congress (1983-1984). A
compromise version of release language, achieved in May 1984, led the 98th
Congress to enact 21 wilderness laws designating 8.6 million acres of wilderness in
21 states — more laws and more acres (outside of Alaska) than any Congress since
the Wilderness System was created.
Since the Wilderness Act created the National Wilderness Preservation System
in 1964, Congress has enacted 103 additional laws designating new wilderness areas
or adding to existing ones, as shown in Table 1. The Wilderness System now
contains 681 wilderness areas with more than 106 million acres in 44 states, managed
by the four federal land management agencies, as shown in Table 3. In addition, the
agencies have recommended another 46.5 million acres in 32 states be added to the
Wilderness System, as shown in Table 4; these lands are generally managed to
protect their wilderness character while Congress considers adding them to the
Wilderness System. Additional lands are being studied by the agencies, to determine
if they should be added to the System, but comprehensive data on lands being
reviewed for wilderness potential are not available.
Questions and discussions persist over the protection and management of areas
that some believe should be designated as wilderness and others believe should be
available for development. The Clinton Administration moved to protect many of
the remaining national forest areas that could be designated as wilderness, initially
in January 1998 with a temporary moratorium on road construction in roadless areas,
and finally with a rule that prohibited most road construction and many other
activities in inventoried roadless areas (i.e., the remaining undesignated RARE II
areas).9 The Clinton rule was twice enjoined, and the Bush Administration has
proposed a new general rule 10 that would allow governors to petition the FS for
separate statewide rules on roadless area management.11
Questions also persist over BLM wilderness study areas. These WSAs are the
areas the BLM studied as potential wilderness under §603 of FLPMA. Under
§603(b), the BLM is required to protect the wilderness characteristics of all WSAs
(including areas not recommended for wilderness) “until Congress determines
otherwise.” Some BLM WSAs have been designated as wilderness by Congress (as
reflected in Table 3), and generally in the same statutes, Congress has released the
BLM from the requirement to protect the wilderness characteristics of certain other
areas. However, release language in BLM wilderness statutes has generally been
more controversial than for national forest areas.12

What Is Wilderness?
The Wilderness Act defines wilderness as an area of generally undisturbed
federal land. Specifically, §2(c) states:
A wilderness, in contrast with those areas where man and his works dominate the
landscape, is hereby recognized as an area where the earth and its community of
life are untrammeled by man, where man himself is a visitor who does not
remain. An area of wilderness is further defined to mean .... an area of
undeveloped Federal land retaining its primeval character and influence, without
permanent improvements or human habitation, which is protected and managed
so as to preserve its natural conditions and which (1) generally appears to have
been affected primarily by the forces of nature, with the imprint of man’s work
substantially unnoticeable; (2) has outstanding opportunities for solitude or a
primitive and unconfined type of recreation; (3) has at least five thousand acres
of land or is of sufficient size as to make practicable its preservation and use in
an unimpaired condition; and (4) may also contain ecological, geological, or
other features of scientific, educational, scenic, or historical value.
This definition provides some general guidelines for determining which areas
should, or should not, be designated wilderness, but there are no specific criteria in
the law. The phrases “untrammeled by man,” “retaining its primeval character,” and
“man’s work substantially unnoticeable” are far from precise. Even the numerical
standard — 5,000 acres — is not absolute; smaller areas can be designated, if they
can be protected, and the smallest wilderness area — Wisconsin Islands in the Green
Bay National Wildlife Refuge — is only 2 acres.
One reason for the imprecise criteria for wilderness is differing perceptions of
what constitutes wilderness. To some, a “wilderness” is an area where there is
absolutely no sign of human presence: no traffic can be heard (including aircraft);
no roads, structures, or litter can be seen. To others, sleeping in a van or camper in
a 400-site campground in Yellowstone National Park is a “wilderness experience.”
Complicating these differing perceptions is the wide-ranging ability to “get away
from it all” in various areas; in a densely wooded area, “getting away” might be
measured in yards, while in mountainous or desert terrain, human developments can
sometimes be seen for miles.
In an attempt to accommodate these contrasting views of wilderness, the
Wilderness Act provided certain exemptions and delayed implementation of
restrictions for wilderness areas, as will be discussed below. At times, Congress has
also responded to the conflicting demands of various interest groups by allowing
additional exemptions for certain uses (especially for existing activities) in particular
wilderness designations. Ultimately, “wilderness areas” are whatever Congress
designates as wilderness, regardless of developments or activities which some might
argue conflict with the definition of wilderness.
Prohibited and Permitted Uses
In general, the Wilderness Act prohibits commercial activities, motorized
access, and roads, structures, and facilities in wilderness areas. Specifically, §4(c)
states:

---

CRS-6
Except as specifically provided for in this Act, and subject to existing private
rights, there shall be no commercial enterprise and no permanent road within any
wilderness area designated by this Act and, except as necessary to meet minimum
requirements for the administration of the area for the purpose of this Act
(including measures required in emergencies involving the health and safety of
persons within the area), there shall be no temporary road, no use of motor
vehicles, motorized equipment or motorboats, no landing of aircraft, no other
form of mechanical transport, and no structure or installation within any such
area.
This section prohibits most commercial resource exploitation (such as timber
harvesting) and motorized entry (via cars, trucks, off-road vehicles, aircraft, or
motorboats) except in emergencies. However, §4(d) provides numerous exceptions,
including (a) possible continued use of motorboats and aircraft; (b) fire, insect, and
disease control measures; (c) mineral prospecting conducted “in a manner compatible
with the preservation of the wilderness environment;” (d) water projects; (e)
continued livestock grazing; and (f) commercial recreation activities.
In addition to these exemptions, the Wilderness Act extended the mining and
mineral leasing laws for wilderness areas in national forests for 20 years, through
1983. New mining claims and mineral leases were permitted for many wilderness
areas, and exploration and development were authorized “subject, however, to such
reasonable regulations governing ingress and egress as may be prescribed by the
Secretary of Agriculture.”13 Despite this authority, no permits for on-site exploration
were considered until James Watt became the Secretary of the Interior in 1981.14
Litigation halted a drilling application in Montana that year, and Congress enacted
a moratorium on wilderness area leasing and exploration in the Department of the
Interior appropriations laws for FY1983 and FY1984 (P.L. 97-394 and P.L. 98-146,
respectively). However, mineral rights existing on or before December 31, 1983 (or
before the area was designated), remain valid, and can be developed if the right-
holder chooses, under “reasonable regulations” determined by the Secretary of
Agriculture, and some mineral exploration has occurred in designated wilderness
areas under such regulations.15
The Wilderness Act also directs that the Act not alter existing federal-state
relationships with respect to state water laws or state fish and wildlife
responsibilities. Specifically, §4(d) (as codified at 16 U.S.C. §1133) states:
13 Most lands in the National Park System and the National Wildlife Refuge System have
been withdrawn from access under the mining and mineral leasing laws, while extensive
BLM wilderness designations were apparently not contemplated until FLPMA was enacted
in 1976. Thus, the Wilderness Act addressed mining and mineral leasing only in the
national forests.
14 Although national forests are managed by the FS in the Department of Agriculture, mining
claims and mineral leases on most federal lands, including the national forests, are
administered by the BLM in the Department of the Interior.

(7) Nothing in this Act shall constitute an express or implied claim or denial on
the part of the Federal Government as to exemption from State water laws.
(8) Nothing in this Act shall be construed as affecting the jurisdiction or
responsibilities of the several States with respect to wildlife and fish in the
national forests.
However, the extent and nature of federal water rights that might arise from
wilderness designations continue to be an important issue for Congress.16
Finally, as noted above, Congress has also enacted numerous exemptions to the
Wilderness Act’s standard prohibitions on activities and developments.17 These
exemptions typically apply to one or a few areas and typically authorize a particular
activity (that might not be permitted under the Wilderness Act’s management
guidance) to be allowed to continue in the area at the level or intensity that occurred
prior to the area’s designation as wilderness.
Statistics on Wilderness Designations and
Recommendations, as of December 31, 2004
The following tables present data on the federal lands managed by the four
principal federal land management agencies and on the acreage designated as
wilderness and recommended by the agencies for wilderness. The data were gathered
from several agency sources, as described below. This section describes the agency
land data shown in Table 2 and the wilderness data shown in Tables 3, 4, and 5.
Agency Land Data. Table 2 shows the area managed by the four major
federal land management agencies.18 The data are not directly comparable across
agencies, however, because of differences in accounting practices. The agency data
also differ from the data maintained by the U.S. General Services Administration
(GSA).19 Differences occur in part because official ownership status often differs
from managerial responsibility; for example, the FS administers 462,678 acres in
Oregon that are technically public (BLM) lands. Another complication is partial
ownership, such as split estates, with the federal government owning only the surface
(or the subsurface), and another owner for the subsurface (or surface) rights;
similarly, some lands are managed by the federal government under easements and
long-term leases, without federal ownership. Thus, the agency acreage statistics in
Table 2 may overstate actual federal land ownership.

and Federal Water Rights, by Pamela Baldwin.
17 See CRS Report RS22025, Wilderness Laws: Prohibited and Permitted Uses, by Ross W.

The data in Table 2 are from agency sources; agency data (rather than GSA
data) were used because they most closely match the agency wilderness data. The
acreage shown in Table 2 is generally limited to the lands owned by the federal
government (i.e., excluding easements and long-term leases) and administered by the
agency or for which the agency has primary management responsibility. This list

Wilderness Statistics: Data Description and Assumptions. The
wilderness statistics presented in Tables 3 and 4 are the current acreage estimates by
the agencies. Acreages are estimates, since few (if any) of the areas have been
precisely surveyed. Table 3 is the acreage for areas that have been designated by
Congress. Table 4 identifies the acreage of areas being protected by the agencies for
possible addition to the Wilderness System, but which have not yet been acted upon
by Congress. In addition, the agencies continue to review the wilderness potential
of other lands under their jurisdiction, both of congressionally designated wilderness
study areas and under congressionally directed land management planning efforts.
However, statistics on acreage being studied, particularly in the planning efforts, are
unavailable.

Wilderness Preservation System, as shown in Table 3. More than 54% of this land
— 57.5 million acres — is in Alaska, and includes most of the wilderness areas
managed by the NPS (76%) and by the FWS (90%). Nearly a third of the Wilderness
System is managed by the FS, but 83% of FS wilderness area is outside Alaska.
Another 46.5 million acres are being protected by various agencies as possible
additions to the Wilderness System, as shown in Table 4. More than half of these
are pending recommendations in the National Park System, and include several large,
well-known areas, such as Yellowstone, Big Bend, Glacier, and Great Smoky
Mountains National Parks. For the FS, Congress has not acted on RARE II
recommendations for Idaho and Montana; the FS data shown in Table 4 are largely
the result of the agency’s land management planning process. The BLM submitted
its recommendations to the President by 1991, as required by FLPMA, and Presidents
Bush and Clinton sent recommendations for BLM wilderness to Congress. The 14.6
million acres of BLM WSAs account for nearly a third of the possible wilderness.
In total, 152.8 million acres, of a total U.S. landmass of 2.27 billion acres, have
been designated as wilderness or are being protected as possible wilderness. Nearly
half of this — 76.0 million acres — is in Alaska, and accounts for 16% of all land in
the state. The remaining 76.8 million acres are distributed among 45 other states;
only Connecticut, Iowa, Kansas, and Rhode Island have no federal lands designated
as wilderness or protected as possible wilderness. Total land designated as or
recommended for wilderness accounts for less than 7% of all land in the United
States, and more than 23% of all federal land.
22 The data in Table 4 are actually the preliminary data from Public Land Statistics, 2004,
which is not yet published, but which corrects the 2003 data for wilderness designated in
P.L. 108-424.
