Wilderness: Legislation and Issues in the 112th Congress

Summary
The Wilderness Act established the National Wilderness Preservation System in 1964 and
directed that only Congress can designate federal lands as part of the system. Free-standing bills
to designate wilderness areas are typically introduced and considered in each Congress; such bills
are not amendments to the Wilderness Act, but typically refer to the act for management guidance
and sometimes include special provisions. Several wilderness bills have been introduced in the
112th Congress.
Wilderness designation can be controversial. The designation generally prohibits commercial
activities, motorized access, and human infrastructure from wilderness areas, subject to valid
existing rights. Advocates propose wilderness designations to preserve the generally undeveloped
conditions of the areas. Opponents see such designations as preventing certain uses and potential
economic development in rural areas where such opportunities are relatively limited.
Most bills direct management of designated wilderness in accordance with the Wilderness Act.
However, proposed legislation also often seeks a compromise among interests by allowing other
activities in the area. Typically, pre-existing uses or conditions are allowed to continue.
Sometimes this authority is temporary, with nonconforming uses to be halted and/or
nonconforming conditions to be rectified. At other times, the authority is permanent, with limited
access permitted for specific areas, uses, and times, or with the authority to operate and maintain
pre-existing infrastructure. Wilderness bills often contain additional provisions, such as
prohibiting buffer zones around the wilderness, or providing special access for particular
purposes, such as border security or Native American religious needs. Water rights possibly
associated with wilderness designations have also been controversial, and many existing statutes
have addressed wilderness water rights in various ways.
Other controversies regarding wilderness have focused on management by federal agencies, such
as how and when an agency releases a wilderness study area that is not recommended as
wilderness. Successful litigation over Forest Service wilderness recommendations in 1980 led
Congress to develop “release language” in legislation. This provision excused the Forest Service
from reviewing wilderness potential and from protecting wilderness conditions in the initial land
management plans for national forests.
The issue of agency management is more contentious for Bureau of Land Management (BLM)
lands, for two reasons. First, BLM is required by law to protect the wilderness characteristics of
its wilderness study areas (WSAs) until Congress determines otherwise. Second, in contrast to
Forest Service planning, the BLM planning process is not cyclical and BLM planning guidance
has not required wilderness consideration in planning. A 1996 attempt by the agency to expand
the original WSAs was challenged in court, and a 2003 settlement agreement resulted in different
BLM wilderness guidance prohibiting additional administrative WSA designations and
protections. In December 2010, however, Interior Secretary Ken Salazar issued an order directing
BLM to maintain a wilderness inventory, to consider wilderness potential in planning, and to
protect wilderness characteristics of the inventoried areas unless alternative management is
deemed appropriate. This policy has received both praise and objections from some members of
Congress, as well as various interest groups.

Wilderness: Legislation and Issues in the 112th Congress

Background
The Wilderness Act (16 U.S. C. §§ 1131-1136) established the National Wilderness Preservation
System in 1964 and directed that only Congress can designate federal lands as part of the system.1
This authority is based on what is known as the Property Clause of the Constitution, which gives
to Congress the “Power to dispose of and make all needful Rules and Regulations respecting the
Territory or other Property belonging to the United States.”2 Many believe that special areas
should be designated to protect and preserve their unique values and characteristics, and bills are
usually introduced in each Congress to designate wilderness areas. Others oppose such legislation
because commercial activities, motorized access, and roads, structures, and facilities generally are
prohibited in wilderness areas. Debate over wilderness legislation in the 112th Congress is likely
to follow this pattern. In addition, a December 2010 change to the Interior Department policy for
wilderness inventory may stimulate debate in the 112th Congress over the timing and nature of
wilderness reviews.
This report presents background information on wilderness protection, a discussion and table
showing the status of pending wilderness legislation in the 112th Congress, and a discussion of
issues in the wilderness debate—the pros and cons of wilderness designation generally; possible
considerations for specific bills; and the possible discussion of wilderness study area designation
and protection.
The Wilderness Act established a National Wilderness Preservation System of federal lands,
initially with 54 wilderness areas containing 9.1 million acres of federal land within the national
forests. It reserved to Congress the authority to add areas to the system, although agencies were
given the authority to review the wilderness potential of certain lands.
The Wilderness Act and 117 subsequent laws have designated wilderness areas. As of December
31, 2010, the National Wilderness Preservation System totaled 759 areas, with 110 million acres.3
The wilderness areas are part of the existing units of federal land administered by the several
federal land management agencies—the Forest Service (USFS) in the Department of Agriculture,
and the National Park Service (NPS), Fish and Wildlife Service (FWS), and Bureau of Land
Management (BLM) within the Department of the Interior. Thus, statutory provisions for these
agencies’ lands, as well as the Wilderness Act and the subsequent wilderness statutes, govern the
administration of the designated wilderness areas.
Wilderness designations can be controversial because the Wilderness Act restricts uses that are
allowed within designated areas. In general, the Wilderness Act prohibits commercial activities,
motorized access, and roads, structures, and facilities in wilderness areas. Specifically, § 4(c)
states:
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 thus prohibits most commercial resource exploitation (such as timber harvesting) and
motorized entry (via cars, trucks, off-road vehicles, aircraft, or motorboats) except for “minimum
requirements” to administer the areas and in emergencies. However, § 4(d) provides numerous
exceptions, including (a) possible continued use of motorboats and aircraft; (b) measures to
control fires, insects, and diseases; (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. Subsequent wilderness statutes have included
additional provisions for administering those wilderness areas, including exceptions to the general
Wilderness Act prohibitions.4
Valid existing rights established prior to the designation of an area as wilderness remain valid,
unless expressly modified by the wilderness statute. The phrase valid existing rights means that
the designation does not alter property rights, and does not suggest that all uses prior to the
designation are allowed. There must be a property right, rather than a general right of use. Courts
have consistently interpreted “subject to valid existing rights” to mean that the wilderness
designation is not intended to take property in violation of the Fifth Amendment of the
Constitution.5 Ownership of land within a wilderness area would confer existing rights.
While most uses—timber harvesting, livestock grazing, motorized recreation—are not rights to
the lands and resources, the mining and mineral leasing laws do provide a process for establishing
rights to the mineral resources. The Wilderness Act allowed implementation of these laws through
1983 for the original areas designated; many subsequent laws explicitly withdrew the designated
areas from availability under these laws. Three statutes—P.L. 97-466, P.L. 101-628, and P.L. 103-
77—directed that mineral leases within the wilderness be acquired through exchanges for mineral
leases elsewhere.
Wilderness Legislation
Numerous bills to designate wilderness areas are usually introduced in each Congress. For
example, 33 bills that would have designated wilderness areas (plus 13 companion bills) were
introduced in the 111th Congress.6 Only one was enacted—the Omnibus Public Land Management
Act of 2009, P.L. 111-11—but it included 16 subtitles (many of which had been introduced in
wilderness bills in the 110th and 111th Congresses) designating 2,050,964 acres of wilderness in
various locales, as well as including numerous land, water, and other provisions.

Issues for Congress
In general, Congress addresses several issues when drafting and considering new wilderness bills.
These issues include the general pros and cons of wilderness designation and specific provisions
included in a bill designating wilderness areas. An issue that could draw attention in the 112th
Congress is a new Interior Department policy on wilderness inventory and consideration for BLM
lands, issued in December 2010.

Wilderness: Legislation and Issues in the 112th Congress

General Wilderness Considerations
Proponents of wilderness generally seek designations of specific areas to preserve the areas in
their current condition and to prevent development activities from altering their wilderness
character. Most areas protected as or proposed for wilderness are undeveloped, with few (if any)
signs of human activity, such as roads and structures. The principal benefit of a wilderness
designation is to maintain such undeveloped conditions and the values that such conditions
generate—clean water, undisturbed wildlife habitats, natural scenic views, opportunities for
nonmotorized recreation (e.g., backpacking), unaltered research baselines, and for some, the
simple knowledge of the existence of such pristine places. These conditions and values may be
constrained by existing rights and other exceptions and exemptions provided for specific areas by
Wilderness Act prohibitions and restrictions on development and access.
Opponents of wilderness generally seek to retain development options for federal lands. The
potential use of lands and resources can provide economic opportunities in extracting and
developing the resources, especially in the relatively rural communities in and around the federal
lands. The principal cost of a wilderness designation is the lost opportunity for economic activity
resulting from resource extraction and development. While some economic activities, such as
grazing and outfitting, are allowed to continue within wilderness areas, many are prohibited. The
potential losses (opportunity costs) for some resources, such as timber harvesting, can be
determined with relative accuracy, since the quality and quantity of the resource can be measured.
However, for other resources, particularly minerals, the assessments of the quality and quantity of
the unavailable resources are more difficult to determine, and thus the opportunity costs are less
certain.
The potential benefits and opportunity costs of wilderness designation can rarely be fully
quantified and valued. Thus, decisions about wilderness generally cannot be based on a clear
cost-benefit or other economic analysis. Rather, deliberations commonly focus on trying to
maximize the benefits of preserving pristine areas and minimize the resulting opportunity costs.
However, the individuals and groups who benefit from wilderness designations may differ from
those who may be harmed by the lost opportunities, increasing conflict and making compromise
difficult. Wilderness designations are not necessarily permanent. Congress has statutorily deleted
lands from 18 wilderness areas, commonly to adjust boundaries to delete private lands or roads
included inadvertently in the original designation. Thus, changes can be made if subsequent
information shows a wilderness designation should be altered.
Considerations for a Wilderness Bill
For legislation to designate wilderness areas, the first choice is which areas (if any) to designate.
While the Wilderness Act required areas of at least 5,000 acres for future designations,7 no
minimum size is required for designations made under new legislation. As a result, wilderness
areas have taken all shapes and sizes; the smallest is the Pelican Island Wilderness in Florida,
with only 5½ acres, while the largest is the Mollie Beattie Wilderness (Arctic National Wildlife
Refuge) in Alaska, with 8.0 million acres. Many wilderness statutes have designated a single area,
or even a single addition to an existing area. Others have designated more than 70 new areas or
additions in a single statute. Some bills address a particular area, while others address all likely

.
Wilderness: Legislation and Issues in the 112th Congress

wilderness areas for a state or sub-state region (e.g., the California desert), usually for one
agency’s lands, although occasionally for two or more agencies’ lands in the vicinity. Typically,
the bill references a particular map for each area, and directs the agency to file a map (with minor
corrections, if necessary) with the relevant committees of Congress after enactment, and to retain
a copy in relevant agency offices (commonly a local office and/or the DC headquarters).
Management in Accordance with the Wilderness Act
Most bills direct that the areas are to be managed in accordance with the Wilderness Act, meaning
human impacts, such as commercial activities, motorized and mechanical access, and
infrastructure developments, are generally prohibited in the areas. The Wilderness Act does allow
some activities that affect the natural condition of the property. Exceptions and exemptions
include access for emergencies and for minimum management requirements; activities to control
fires, insects, and diseases; livestock grazing; and presidentially authorized water projects.
Subject to valid existing rights, the areas are withdrawn from the public land laws and the mining
and mineral leasing laws. Acquisition of nonfederal lands is authorized from willing sellers, and
“reasonable access” to nonfederal lands within the wilderness area must be accommodated. State
jurisdiction over and responsibilities for fish and wildlife and water rights are unaffected.
Non-Conforming Uses or Conditions
Lands do not have to be untouched by humans to be eligible for statutory designation as
wilderness. Provisions could be included to terminate or accommodate any non-conforming uses
or conditions in the areas included in the bill. Existing wilderness statutes have directed
immediate termination of non-conforming uses or have allowed such uses to continue for a
specified period. Similarly, existing statutes typically have provided the agencies a specified
period for removing, remediating, or restoring non-conforming conditions or infrastructure.
Alternatively, many non-conforming uses and conditions have been permitted to remain in
designated wilderness areas. The Wilderness Act explicitly allowed continued motorized access
by aircraft and motorboats in areas where such uses were already established. Numerous
wilderness statutes have permitted existing infrastructure (e.g., cabins, water resource facilities,
telecommunications equipment) to remain, and have authorized occasional motorized access to
operate, maintain, and replace the infrastructure. A few statutes have also allowed new
infrastructure developments (e.g., telecommunications equipment and a space energy laser
facility) within designated wilderness areas. While such authorizations are usually for a specific
area, some statutes have provided more general exemptions, such as for maintaining grazing
facilities or for fish and wildlife management by a state agency in all areas designated in the
statute.
Courts have looked narrowly at these exceptions, however. Accordingly, legislative language to
continue these uses should be precise. For example, in one case, the law creating a wilderness
specifically allowed the management agency to “upgrade, maintain and replace” one structure.
The court held that did not mean that Congress intended preservation of other structures in that
wilderness.8 In another case, the Eleventh Circuit stated that unless the enabling legislation
permitted it, maintenance and preservation of structures, even those deemed historic, could not be
permitted: “Congress wrote the wilderness rules and may create exceptions as it sees fit. Absent

these explicit statutory instructions, however, the need to preserve historical structures may not be
inferred from the Wilderness Act nor grafted onto its general purpose.”9
Other Provisions
Many existing wilderness statutes have included various other provisions addressing wilderness.
Some have included sections with findings and purposes for the designation; these are more
common in statutes that include designations or management direction for areas other than
wilderness (e.g., directing cooperative management of an area or designating a national recreation
area). Many have also included provisions that prohibit buffer zones around the wilderness. Such
provisions direct that non-conforming activities can occur up to the wilderness boundary, and that
the ability to see or hear a non-conforming activity from within the wilderness is not a reason to
prohibit the activity.
Some statutes have contained additional wilderness management provisions. While these may
address non-conforming uses or conditions, as discussed above, sometimes the provisions include
additional guidance to supplement the management provisions of the Wilderness Act. Specific
references to certain wilderness statutes and/or to the accompanying committee reports have been
included in many statutes for additional guidance on livestock grazing. Also, several statutes have
contained additional guidance on appropriate and acceptable state fish and wildlife management
activities within the wilderness areas.
Numerous statutes have contained provisions addressing specific issues, as discussed below:
special access considerations; release language; and reserved water rights.
Special Access Considerations
Various existing wilderness statutes have included special access provisions for particular needs.
For example, statutes designating wilderness areas abutting or adjacent to the Mexican border
have commonly allowed motorized access for law enforcement and border security. Similarly,
several statutes have included provisions addressing possible military needs in and near the
designated areas, particularly for low-level military training flights. Other statutes have contained
provisions allowing particular access for tribal, cultural, or other local needs. Several statutes
have included provisions authorizing the agencies to prevent public access, usually temporarily
and for the minimum area needed, to accommodate these and other particular needs.
Release Language
Many areas must be managed to preserve their wilderness characteristics. For example, § 603(c)
of the Federal Land Policy and Management Act of 1976 (FLPMA) directed BLM to administer
the lands it reviewed as potential wilderness “until Congress has determined otherwise … in a
manner so as not to impair the suitability of such areas for preservation as wilderness.”10 Thus,
BLM must protect the wilderness character of all of its wilderness study areas, until Congress
releases the areas from this management direction. When Congress considers which areas to
designate as wilderness, and chooses not to designate some areas as wilderness, it commonly

.
Wilderness: Legislation and Issues in the 112th Congress

includes release language to allow BLM to administer the lands not designated under the general
public land management provisions of FLPMA. (This issue is discussed further below.)
Reserved Water Rights
Under the so-called Winters doctrine, when Congress reserves federal land for a particular
purpose, it also reserves enough water to fulfill the purpose of the reservation.11 Initial wilderness
designations were seen as having a minimal effect on water rights, as they were made in national
forests, which are congressional reservations of federal land; in § 4(d)(7), the Wilderness Act
explicitly stated that the wilderness designations did not “constitute an express or implied claim
or denial … as to exemption from State water laws.” This is particularly an issue for BLM lands,
since many BLM lands are public domain lands (acquired by the federal government from a
foreign sovereign) that were not reserved by Congress. Furthermore, as BLM lands often do not
contain the headwaters of streams (in contrast to the national forests), upstream diversions can
affect the water flowing through a wilderness area. As discussed elsewhere (see CRS Report
RL33827, Wilderness Laws: Permitted and Prohibited Uses), wilderness statutes have taken
various approaches to water rights. Addressing federal water rights might be warranted in
wilderness legislation, especially for places that have constraints on the amount of water
available.
Wilderness Review and Release of Possible Wilderness
One particular issue that might arise in the 112th Congress is when (and whether) the agencies can
and must review the wilderness potential of their lands. Order 3310, issued by Interior Secretary
Ken Salazar on December 22, 2010, changed BLM policy established by the previous Secretary
in September 2003 to inventory potential wilderness resources and to protect the wilderness
characteristics of those inventoried areas. This policy change may stimulate debate over this issue
in the 112th Congress.
Background
The Wilderness Act and other statutes have directed the review of the wilderness potential of
certain federal lands. The Multiple Use Sustained Yield Act of 196012 and the National Forest
Management Act of 1976 (NFMA)13 provide for periodic review of potential national forest
wilderness areas in the USFS planning process for the national forests.14 In 1977, the USFS chose
to accelerate the wilderness review portion for the initial plans, issuing the Second Roadless Area
Review and Evaluation (RARE II) final environmental impact statement and wilderness
recommendations in January 1979. A successful judicial challenge to those recommendations by
the state of California15 led to uncertainty over the validity of the RARE II recommendations, to

ambiguity over the timing of future wilderness reviews, and to disputes over the need to protect
the wilderness characteristics of the areas reviewed. Congress developed “release language” for
wilderness legislation to release the USFS from reviewing wilderness potential in the initial
NFMA plans (essentially redoing RARE II) and from preserving the wilderness characteristics of
areas not recommended for wilderness designation. Such provisions were enacted in 30 state-by-
state USFS wilderness statutes between 1980 and 1990.16 Release language is no longer
significant for national forest wilderness legislation because review of potential wilderness is now
part of the NFMA planning process.
BLM Wilderness Review
For BLM lands, § 603 of FLPMA requires the agency to review the wilderness potential of “those
roadless areas of five thousand acres or more and roadless islands of the public lands, identified
during the inventory required by section 201(a) of this Act as having wilderness characteristics.”
The agency was required to present its wilderness recommendations to the President within 15
years of October 21, 1976, and the President then had two years to submit his wilderness
recommendations to Congress. BLM presented its recommendations by October 21, 1991, and
Presidents George H. W. Bush and William Clinton submitted wilderness recommendations to
Congress. In response, Congress has enacted several statutes designating BLM wilderness areas,
but many of the wilderness recommendations for BLM lands remain pending. There are two
continuing issues for potential BLM wilderness: protection of the wilderness study areas; and
future BLM wilderness reviews.
Protection of BLM Wilderness Study Areas
BLM has a continuing obligation to identify the resources on its lands, giving priority to areas of
critical environmental concern.17 An additional obligation required a review of roadless areas
greater than 5,000 acres to determine suitability for wilderness.18 In 1977-1979, BLM identified
suitable wilderness study areas (WSAs) from those roadless areas in its initial resource inventory
under § 201. Section 603(c) of FLPMA directs the agency to manage those lands “until Congress
has determined otherwise … in a manner so as not to impair the suitability of such areas for
preservation as wilderness.” Thus, BLM must protect the WSAs like they were wilderness until
Congress enacts legislation that releases BLM from that responsibility. This is sometimes referred
to as a nonimpairment obligation.
Legislation to broadly modify WSA nonimpairment protection under § 603 of FLPMA was
offered in earlier Congresses (106th, 107th, and 108th). The legislation typically provided release
for all remaining BLM WSAs 10 years after enactment, to provide time for Congress to consider
wilderness legislation for BLM lands, meaning that if Congress had not acted by that time, the
areas would no longer be treated as WSAs. However, no hearings were held on the bills and none
was enacted. Similar bills have not been introduced since the 108th Congress.

Wilderness: Legislation and Issues in the 112th Congress

WSAs have been subject to litigation challenging BLM’s protection. In the early 2000s, BLM
was sued for not adequately preventing impairment of WSAs from increased off-road vehicle use.
The issue was whether the nonimpairment obligation was discretionary and therefore
unenforceable by litigation. In Norton v. Southern Utah Wilderness Alliance, the U.S. Supreme
Court ruled that it was not enforceable by suit.19 The Court held that while WSA protection was
mandatory, it was a broad programmatic duty and not a discrete agency obligation. The Court also
concluded that the relevant FLPMA land use plans (indicating that WSAs would be monitored)
constituted only management goals that might be modified by agency priorities and available
funding, and were not a basis for enforcement under the Administrative Procedure Act (APA).
Therefore, it appears that although BLM actions that would harm WSAs could be enjoined, as
with any agency enforcement obligation,20 forcing BLM to take protective action is difficult at
best.
Future BLM Wilderness Reviews
It is unclear whether BLM is required to review its lands specifically for wilderness potential
after the initial review required within 15 years in § 603(a) of FLPMA.21 In contrast to the USFS,
which must revise its land and resource management plans at least every 15 years, BLM is not
required to revise its plans on a specified cycle; rather it must to revise its land and resource
management plans “when appropriate.” And BLM is required under § 201 to maintain an
inventory of the resource values of its lands, prioritizing those of critical environmental concern.
Furthermore, while NFMA includes wilderness in the planning process, both directly and by
reference to the Multiple Use Sustained Yield Act of 1960, FLPMA is silent on wilderness in the
definitions of multiple use and sustained yield and in the guidance for the BLM planning process.
Thus, the potential for future BLM wilderness reviews is less certain than for future USFS
wilderness reviews.
In 1996, then-DOI Secretary Bruce Babbitt used the authority to inventory lands and resources in
§ 201 of FLPMA to identify 2.6 million acres in Utah as having wilderness qualities. This was in
addition to the lands inventoried and reviewed in the 1970s and 1980s. The state of Utah
challenged the inventory as violating the review required by § 603, and in September 2003, then-
DOI Secretary Gale Norton settled the case.22 She issued new wilderness guidance (Instruction
Memoranda Nos. 2003-274 and 2003-275) prohibiting further reviews and limiting the term

Wilderness: Legislation and Issues in the 112th Congress

274 advised that because the § 603 authority expired, “there is no general legal authority for the
BLM to designate lands as WSAs for management pursuant to the non-impairment standard
prescribed by Congress for Section 603 WSAs.” The Wilderness Inventory and Study Procedures
Handbook was rescinded by these memoranda.
On December 22, 2010, DOI Secretary Ken Salazar issued Order No. 3310, addressing how BLM
would manage wilderness.24 This order indirectly modifies the 2003 wilderness guidance without
actually overturning the direction (or even acknowledging it). The order “affirms that the
protection of the wilderness characteristics of public lands is a high priority.” It relies on the
authority in § 201 to inventory lands with wilderness characteristics that are “outside of the areas
designated as Wilderness Study Areas and that are pending before Congress” and designates these
lands as “Wild Lands.” It also directs BLM to consider the wilderness characteristics in land use
plans and project decisions, “avoiding impairment of such wilderness characteristics” unless
alternative management is deemed appropriate. While Instruction Memorandum 2003-274 (which
was issued by the BLM Director) indicated that, except for § 603 WSAs, the nonimpairment
mandate did not apply, Order No. 3310 appears to require an affirmative decision that impairment
is appropriate in a § 201 wilderness resource area, or otherwise must be avoided. Forthcoming
revisions to the BLM Manual (directed by the order) are expected to explain how that standard
will be carried out.
The chair of the House Natural Resources Subcommittee on National Parks, Forests, and Public
Lands, Representative Rob Bishop, “said one of his top priorities will be grilling Interior
Secretary Ken Salazar” on the new policy.25 Uintah County and the Utah Association of Counties
have expressed similar opposition to the policy change, while others have praised the change.26
Concluding Remarks
Legislation is typically introduced in each Congress to add areas to the National Wilderness
Preservation System. Many interests favor wilderness designations as a means of preserving the
existing pristine nature of the areas; others oppose wilderness because it may prevent the
development and use of the resources contained in the areas. Wilderness legislation commonly
refers to the 1964 Wilderness Act for management direction, but many bills contain additional
provisions with special guidance to allow limited, nonconforming access or infrastructure within
the designated areas.
A policy change announced by the Secretary of the Interior in December 2010 would require the
BLM to maintain an inventory of potential wilderness and to consider preserving the wilderness
characteristics of those areas in its land and resource management planning process. This change
may stimulate additional attention to and oversight of wilderness during the 112th Congress.
