Does the Endangered Species Act Listing Provide More Protection of the Polar Bear?
Summary
The polar bear has been protected under the Marine Mammal Protection Act (MMPA) since 1972,
meaning that it is illegal to kill or harass the bear or to transport or trade its parts (with a few
exceptions). The Endangered Species Act (ESA) also prohibits killing or harming listed species.
Some ask: If it was already illegal to kill or harm the bear when the U.S. Fish and Wildlife
Service listed the bear as threatened on May 15, 2008, what protections were provided by the
listing?
One example of increased protection is that ESA threatened species are categorized as depleted
species under the MMPA, meaning that polar bear trophies may no longer be imported from
sport-hunts in Canada under that MMPA exception. Approximately 80 bears a year were
permitted for import under this program. Proposed legislation would change that. H.R. 1054
would allow import of polar bears that were legally taken prior to the ESA listing, and H.R. 1055
would revise the MMPA to allow continued import of polar bears, regardless of their status. S.
1395 would also allow continued import of polar bear trophies, but would further modify the act
to allow imports even when it would have a significant impact on the Canadian population of
bears and regardless of whether it is otherwise consistent with the MMPA. H.R. 5379 would
statutorily revoke the listing.
Another protection offered by the ESA listing is habitat protection. The ESA has several
provisions that function to protect not just the bear, but its habitat. While the MMPA has habitat
protection as a purpose, it does not require any habitat conservation measures or punish habitat
destruction. FWS proposed designating critical habitat in May 2010 (revising a proposed
designation of October 2009); therefore, that environmental protection would be available when
final. FWS estimates that the additional expense of considering adverse impacts on critical habitat
could total $53,900 per year. The ESA requires another system that might protect the bear—
establishing a recovery plan—but FWS has not completed the process. When a recovery plan is
prepared, it would establish recovery goals and trigger congressional monitoring of the polar
bear’s progress.
The Special Rule for the polar bear, under Section 4(d) of the ESA, may have minimized some
protections the listing otherwise may have provided. The Special Rule describes when the MMPA
applies and when the ESA applies, harmonizing some provisions of the two laws, a possible
benefit for MMPA permit holders. The polar bear Special Rule also eliminates some protections
that the ESA might have provided—such as those relating to incidental takes, subsistence users,
or citizen suits—by continuing the MMPA protections. The Special Rule also adds a different
standard for certain military actions. Had the polar bear been listed as an endangered species,
rather than threatened, there would be no Special Rule. Arguably, polar bears would have been
more protected.
A November 2010 court ruling could lead to the end of the Special Rule. The D.C. District Court
remanded the listing decision, requiring FWS to justify its rationale by December 23, 2010. If
FWS cannot satisfy the court, and the court directs an endangered determination, the Special Rule
would cease to apply.
The Omnibus Appropriations Act of 2009 (P.L. 111-8) gave the Secretary of the Department of
the Interior discretion to withdraw or reissue the Special Rule within 60 days. No change was
made.

Does the Endangered Species Act Listing Provide More Protection of the Polar Bear?
n May 15, 2008, the Fish and Wildlife Service (FWS) listed the polar bear as a threatened
species under the Endangered Species Act (ESA).1 Some have questioned the need to use
O the ESA to protect the bear, citing other treaties, statutes, and regulations that protect
polar bears, primarily the Marine Mammal Protection Act (MMPA).2 Others are concerned that
the listing could inhibit natural resource development in the bear’s Arctic habitat. This report
discusses what additional protections are provided by the ESA listing that were not available
before.
FWS considered existing regulatory protections before listing the polar bear. That is one of the
five factors ESA requires when making a listing determination.3 FWS found that “potential
threats to polar bears from direct take, disturbance by humans, and incidental or harassment take
are, for the most part, adequately addressed through international agreements, national, State,
Provincial or Territorial legislation, and other regulatory mechanisms.”4 However, the polar bear
was listed because the bear’s primary habitat of sea ice was threatened with destruction due to
global climate change. FWS found that the bear was likely to become endangered in the
foreseeable future.
A federal court held that FWS’s rationale for listing the bear as threatened, instead of endangered,
was not consistent with the ESA.5 FWS had found that to be endangered under the act, a species
must be in imminent danger of extinction, and since the polar bear was not in immediate risk of
extinction, it was not endangered. The court found no such support for an immediacy factor in the
ESA. Instead, it said the statute was deliberately ambiguous. The court directed FWS to provide
support for its interpretation. FWS’s submission is due by December 23, 2010, with the other
parties given the opportunity to respond. A hearing is scheduled for February 23, 2011. In the
meantime, the threatened status of the polar bear remains unchanged.
Protections
The ESA and the MMPA have similar provenances. Both appeared during the high tide of
environmental legislation of the late 1960s and early 1970s. Both are written to protect species
and their habitats. The Endangered Species Act has a broad purpose. It is intended to “provide a
means whereby the ecosystems upon which endangered species and threatened species depend
may be conserved, [and] to provide a program for the conservation of such endangered species
and threatened species....”6
Similarly, the MMPA addresses both habitat and individual protection: “efforts should be made to
protect essential habitats, including the rookeries, mating grounds, and areas of similar
significance for each species of marine mammal from the adverse effect of man’s actions.”7

Prohibitions
Both the MMPA and the ESA prohibit taking or transporting species protected under the acts.8
The ESA definition of take includes harm, which means killing or injuring wildlife, including
significant habitat disruption that impairs essential behavioral patterns.9 Take also includes
harass, meaning an action likely to injure by significantly disrupting normal behavioral
patterns.10 Under the MMPA the term take includes “harass, hunt, capture, or kill, or attempt to do
those activities.11 Harass means an act with “the potential to injure a marine mammal” (Level A
harassment), or “has the potential to disturb a marine mammal ... by causing disruption of
behavioral patterns” (Level B harassment). By being listed under both statutes, the bear enjoys
the protections of both.
The ESA regulatory definition of harm has been interpreted to mean habitat disturbance by itself
can function as a take, although courts have not uniformly agreed on this. The courts’
disagreement centers on whether a species must be injured or killed before the statute has been
violated. The Ninth Circuit (whose jurisdiction includes Alaska, the bear’s U.S. habitat) has
interpreted taking broadly as it applies to habitat modification. The court held that if an injury to
wildlife occurs as a result of the habitat change, either in the past, present, or future, the
definition’s injury requirement is satisfied.12 This could be an advantage to polar bear protection
under the ESA, as the MMPA does not directly prohibit habitat destruction.
However, not all courts will find a take based on habitat destruction without an actual injury. For
example, one district court said that an injury must occur before a prohibited taking may be found
and that “habitat modification or degradation, standing alone, is not a taking pursuant to section
9.”13
Special Rule
The ESA allows FWS to issue Special Rules for species listed as threatened where the agency
deems it “necessary and advisable to provide for the conservation of such species.”14 They are
known as Section 4(d) rules or Special Rules. Special Rules supplant the general regulations that
apply to all threatened species and can reduce those protections.15 The rules apply just to that one

species. A Special Rule was issued for the polar bear at the time of the listing16 and made final in
December 2008.17 In essence, the polar bear Special Rule harmonizes the requirements of the
MMPA and the ESA, saying that compliance with the MMPA will be treated as compliance with
the ESA.18 It is discussed in more detail later in this report.
Only four other species protected under the MMPA are also listed as threatened under the ESA:
the eastern population of the stellar sea lion, the Guadalupe fur seal, and the northern and
southern sea otters. Of these, only the northern sea otter has a Special Rule, which applies only to
one distinct population of the species.19
Congress authorized the Secretary of the Interior to “withdraw or reissue” the Special Rule within
60 days of the Omnibus Appropriations Act of 2009 (Omnibus Act).20 Public notice and comment
were waived by the Omnibus Act. The Secretary did not act to change the Special Rule.
Exceptions
Both the MMPA and the ESA have exceptions to their prohibitions. Permits may be issued under
either statute for taking a species for scientific purposes or to enhance the survival of the
species.21 Both have provisions for incidental takes.22 Both have exceptions for national
security.23 Only the MMPA, however, provides for issuing permits to take marine mammals for
public display; for photography, educational, or commercial purposes; and to import polar bear
parts from bears sport-hunted in Canada.24 Some limits apply to those MMPA permits. The
MMPA also provides specific incidental take permit standards for military readiness activities.25
Sport-Hunted Polar Bears
Under Section 1371(a)(3)(B) of the MMPA, once a species is designated as depleted under the
act, no permits may be issued for importing sport-hunt trophies. Being listed as a threatened
species is one way a species is declared to be depleted. Accordingly, the ESA listing eliminated
the MMPA permit for importing polar bear trophies from Canada.26 Approximately 80 permits a

year were issued under this program. That is one way in which the May 15, 2008, listing
increased protection of the bears. (See “Congressional Action,” below, for a discussion of
legislation that would reinstate this program.)
Incidental Takes in General
As stated above, both the ESA and the MMPA allow incidental takes of species protected under
the acts.27 There are differences between the two programs. Under the ESA, incidental takes are
divided into two categories: Section 10 takes by citizens, which are authorized by incidental take
permits; and Section 7 consultations for takes by federal agencies, which are authorized by
incidental take statements.28 The MMPA has two types of takes based on the severity of the
action: incidental take authorizations (ITAs), also known as Letters of Authorization, for killing or
injuring animals; and incidental harassment authorizations, for lesser takes.29 All have statutory
authorization, but the details are in the regulations.
Ordinarily, ESA incidental takes for threatened species are governed under regulations found at
50 C.F.R. § 17.32. An incidental take permit is issued. The rules require that applicants for such a
permit include a description of the activity, the names and numbers of the species, and a habitat
conservation plan (HCP). The applicant must describe the steps it will take to monitor, minimize,
and mitigate any impacts to the threatened species in an HCP; alternative actions and why they
are not being used; and any other necessary and appropriate measures imposed by FWS.30
Permission for an MMPA incidental take requires an applicant to submit data about the project
and the impacted animals, and to suggest mitigation.31 The application is reviewed using the best
scientific evidence. The MMPA requires monitoring and reporting during the time the take is
authorized.
Even though both statutes allow incidental takes, the steps to obtain those permits are different.
Under the ESA, the incidental take permits are issued to an individual (which can be a
corporation).32 Under MMPA the incidental take authorizations are issued for an activity,
instead.33 The language of the MMPA allows U.S. citizens to seek authorization for specified

27 The terms are defined slightly differently by the regulations of each act. In the MMPA, incidental, but not
intentional, taking is defined as “takings which are infrequent, unavoidable, or accidental.” 50 C.F.R. § 18.27(c). In the
ESA, incidental taking is defined as “any taking otherwise prohibited, if such taking is incidental to, and not the
purpose of, the carrying out of an otherwise lawful activity.” 50 C.F.R. § 17.3. The ESA definition essentially leaves
the definition of incidental to the dictionary, which, according to Webster’s New Collegiate Dictionary, means
“occurring merely by chance or without intention; or being likely to ensue as a chance or minor consequence.”

activities to allow the incidental take of “small numbers of marine mammals” for five-year
periods, provided that the taking will have a negligible impact on such species and will not
overdeplete animals available to subsistence users.34 Similar permission may be provided for one-
year periods for activities that incidentally harass small numbers of marine mammals.35 Another
difference between the incidental take permit under the ESA and the MMPA equivalent is that the
ESA permit can be valid for decades, even 100 years. The MMPA authorization is valid for five-
year periods, although it can be renewed. It is not clear whether this difference protects the polar
bear, however.
The two acts diverge regarding military activities that could result in an incidental take. The
MMPA exempts activities “necessary for national defense”36 from the permitting process. The
exemption is limited to a two-year period, which can be renewed. There is also a separate
standard for military readiness activities seeking incidental take authorizations.37 That standard
provides that when determining whether such an activity will have the “least practicable adverse
impact” on a species, the Service will consider “personnel safety, practicality of implementation,
and impact on the effectiveness” of the activity. Under the ESA, a special committee may exempt
military actions deemed by the Department of Defense (DOD) as necessary for national
security.38 The exemption applies only to a specific action, and not to a category of actions as
allowed under the MMPA.
Special Rule for Polar Bears
For the most part, the Special Rule for the polar bear establishes that the MMPA, not the ESA,
governs. It addresses incidental takes, subsistence users, military exemptions, and citizen suits. In
contrast, the Special Rule for the distinct population segment of the northern sea otter pertained
only to use of sea otter parts in native handicrafts.
Incidental Takes
The incidental take provisions of 50 C.F.R. § 17.32 generally apply to threatened species, but
because there is a Special Rule under Section 4(d) of the ESA for the polar bears, that regulation
does not apply. Instead the Special Rule provides the process for incidental takes. In the rule FWS
states that there will be no change for incidental takes of polar bears now that the species is listed
under the ESA. The rule for taking polar bears will be the same as it was under the MMPA: “if
incidental take has been authorized under section 101(a)(5) of the MMPA, either by the issuance
of an Incidental Harassment Authorization or through incidental take regulations, we will not
require an incidental take permit issued in accordance with 50 CFR 17.32(b).”39

Does the Endangered Species Act Listing Provide More Protection of the Polar Bear?
According to FWS, the standard for incidental takes under the MMPA is more restrictive. FWS
says that the MMPA definition of negligible impact, which is defined as “an impact that cannot be
reasonably expected to, and is not reasonably likely to, adversely affect the species through
effects on annual rates of recruitment or survival,”40 is “a more protective standard than [the ESA]
requirement.”41 Based on this representation, following the ESA would not increase protections
for the polar bear.
Having an MMPA incidental take authorization instead of the ESA equivalent could provide an
advantage for applicants: no HCP has to be negotiated and approved. The HCP application
process can be involved—FWS recommends creating steering committees to develop the scope of
the HCP and mitigation programs, and has issued a handbook to guide applicants.42 However, it is
not clear if this provides additional protection of the bear. The HCP is one way in which the ESA
protects habitat of listed species. HCPs are intended to provide for the restoration and protection
of the listed species’ habitat.43 No such plan is required by the MMPA, and no habitat protection
or restoration is required, although applicants are required to discuss methods to make the least
impact on the species and habitat.
MMPA Incidental Take Authorizations (ITAs) are currently valid for the oil and gas industry in
polar bear habitat. An ITA has been in place for oil and gas activities in the Beaufort Sea since
1993. The most recent ITA for Beaufort Sea was issued in 2006.44 An ITA for the Chukchi Sea is
effective from June 11, 2008, to June 11, 2013.45
Climate Change Issues Related to Incidental Takes
The Special Rule alters how climate change may be considered in the context of the polar bear in
two ways: limiting the areas in which private actions may be liable for a taking of a bear; and
limiting the ability of citizens to sue. Some believed listing the polar bear under the ESA would
allow challenges to actions that adversely affected the climate.46 The theory was that projects that
would increase greenhouse gas emissions, such as power plant operations or automobile emission
standards, would adversely affect the bear by contributing to habitat loss. FWS addresses this
theory in the Section 4(d) rule, at 50 C.F.R. § 17.40(q)(4). Specifically, under the Special Rule, if
an incidental take of polar bears results from activities outside of the current range of the polar
bear, that act is not prohibited by the ESA.47 This suggests that operating a power plant, for
example, in any state but Alaska would not require an incidental take permit for harming polar
bears because that activity is outside of the polar bear’s current range.
However, this exclusion applies only to private parties and not to actions of the federal
government. The Special Rule explicitly states “the special rule does not remove or alter in any

way the consultation requirements under section 7 of the ESA.”48 Section 7 is the process by
which federal agencies obtain permission for incidental takes. Federal agencies would have the
same consultation requirements for their actions in Alaska as outside of Alaska. So an agency
issuing a permit for a power plant outside of the polar bear’s range still needs to conduct a section
7 consultation.
However, the Special Rule limits citizen suit challenges against the federal government for
actions that may harm polar bears. The Special Rule limits citizen suits for takings to actions that
occur in the current range of the polar bear. To continue the example, if a citizen is dissatisfied
with the results of a consultation that found a permit for a non-Alaskan power plant would not
jeopardize the polar bear, the citizen would not be able to challenge this conclusion under the
ESA.
Incidental Takes and Military Actions
Because the Special Rule categorizes incidental takes as being governed by the MMPA, the
exemption available to the military applies to actions affecting the polar bear. The ESA equivalent
exemption is more limited in that it applies to only one action, not a category of actions. As
mentioned above, two types of military actions are addressed by the MMPA: activities “necessary
for national defense,”49 which are exempted; and military readiness activities, which have
separate standards for incidental take authorizations.50
Citizen Suits
The ESA contains an enforcement provision that the MMPA does not; however, the Special Rule
limits its reach. The ESA allows citizens to take action against other citizens to halt violations of
the act.51 The citizen suit provision could provide additional protection for the polar bear, if
citizen enforcers use it. It allows “any person” to give 60 days’ written notice of a violation to an
alleged violator and FWS. If FWS or the United States has not begun an action to redress the
violation or otherwise punish the violator by the end of 60 days, a civil suit may be filed to enjoin
the violation. In practice, however, the citizen suit provision primarily is used against federal
agencies and rarely against anybody else. Citizens may bring suit against a federal agency for
violations of the MMPA by using the Administrative Procedure Act (APA).
The Special Rule limits the citizen suit provision by recategorizing many possible incidental take
claims as an MMPA issue. According to FWS, the citizen suit provision would apply in two
circumstances: 1) claims not based on incidental takes; or 2) claims based on incidental takes
where the activity occurred within Alaska.52 This means that only the government could enforce
MMPA violations regarding an unauthorized take based on an activity outside of the current range
of the polar bear.53

Does the Endangered Species Act Listing Provide More Protection of the Polar Bear?
Subsistence Users
The two acts have different provisions regarding how Native Alaskans may take polar bears. It is
not clear that the ESA listing provides additional protections for the polar bear regarding
subsistence users. FWS says that the MMPA rule is more restrictive and that under the Special
Rule it will treat compliance with the MMPA as compliance with the ESA,54 in essence
neutralizing any additional protections the ESA may have provided. Both laws provide
exemptions for Alaskan Natives to take species for subsistence purposes.55 The definition of
subsistence users is more restrictive in the MMPA than the ESA. Both allow Indians, Aleuts, and
Eskimos to kill polar bears for subsistence use. However, the ESA also allows non-native
permanent residents of an Alaska native village to take for subsistence use under Section 10(e).56
On the other hand, the ESA allows only subsistence use in its exception, while the MMPA also
permits Alaskan natives to use polar bears for commercial sale of traditional handicrafts made of
polar bear parts.57
Section 7 Consultations
The Section 7 consultation provision under the ESA has no parallel in the MMPA. Under Section
7 federal agencies must consult with FWS before committing significant resources toward an
action that may jeopardize a listed species or harm its critical habitat.58 This requirement is known
as a Section 7 consultation. There is no similar separation of federal and private actions in the
MMPA.
The Section 7 consultation can be a time-consuming and litigious activity. A look at 51 cases in
the last decade in which a court found that FWS or NMFS did not comply with the ESA shows
that 15 of those cases involved Section 7 consultations. It is a primary reason given by the State
of Alaska for its lawsuit against FWS for listing the polar bear under the ESA.59 Alaska fears that
the oil and gas industry will forgo exploration and development in the state due to the extra
requirements that the ESA imposes.60
Under the ESA, federal agencies are required to consult with FWS or NMFS to ensure that
federal actions are not likely to jeopardize the continued existence of a listed species or result in
the adverse modification of habitat.61 FWS indicated the Special Rule does not alter Section 7
consultations:
These requirements under the ESA remain unchanged under this rule regardless of whether
the action occurs inside or outside the current range of the polar bear. This special rule does
not negate the need for a Federal action agency to consult with the Service to ensure that any

action being authorized, funded, or carried out is not likely to jeopardize the continued
existence of the polar bear.62
As for existing MMPA incidental take authorizations for federal actions relating to the oil and gas
industry, FWS says that it believes the ITAs are harmonious with ESA consultation requirements
and that no additional measure would be required
to the extent that any Federal actions comport with the standards for MMPA incidental take
authorization, we would fully anticipate any such section 7 consultation under the ESA
would result in a finding that the proposed action is not likely to jeopardize the continued
existence of the polar bear. In addition, we anticipate that any such proposed action(s) would
augment protection and enhance agency management of the polar bear through the
application of site-specific mitigation measures contained in authorization issued under the
MMPA.63
Similarly, FWS anticipates no additional administrative burden for federal actions related to
commercial fisheries: “[we anticipate that] a consultation on commercial fishery activities in
Alaska would result in a ‘no effect’ determination under section 7 of the ESA.”64
Habitat and Critical Habitat
The polar bear was listed as a threatened species because the loss of its habitat made it likely to
become endangered. Habitat protection, therefore, is significant to the bear. The United States
committed by treaty to protect the habitat of the polar bear. In 1973, the United States, Canada,
Denmark, Norway, and the former Union of Soviet Socialist Republics entered an international
agreement to protect polar bears.65 The United States ratified the Agreement on the Conservation
of Polar Bears in 1976. In addition to prohibiting the take of polar bears, the Agreement also
requires actions to protect their habitat. Article II requires the Parties
• to take appropriate action to protect the ecosystem of which polar bears are a
part;
• to give special attention to habitat components such as denning and feeding sites
and migration patterns; and
• to manage polar bear populations in accordance with sound conservation
practices based on the best available scientific data.
In addition to the international obligation to protect polar bear habitat, the ESA prohibits habitat
destruction that injures an animal and requires parties planning actions that could result in
incidental takes to develop plans to protect habitat. Additional habitat protections under the ESA
apply at a time critical habitat is designated for a species when federal agencies must consult with
62 73 Fed. Reg. at 76252. The consultation regulations were revised in 2008, limiting how effects from “global
processes” such as climate change would be considered in the Section 7 process. For an analysis of the revised
regulations, see CRS Report RL34641, Changes to the Consultation Regulations of the Endangered Species Act (ESA),

a Service regarding the effects of its actions on critical habitat. No critical habitat has been
designated for the polar bear, although a proposed designation has been made.66
The ESA defines critical habitat as “the specific areas within the geographical area occupied by
the species, at the time it is listed ... on which are found those physical or biological features (I)
essential to the conservation of the species and (II) which may require special management
considerations or protection.”67 It also includes areas outside the geographical area occupied by
the species if those areas are deemed essential for the conservation of the species. There is no
similar provision in the MMPA.
The ESA requires FWS to designate areas of critical habitat and to make that designation based
on the best scientific data available after taking into consideration the economic impact.68 Critical
habitat has not been designated for every listed species, however.69 The advantage to a species of
having critical habitat designated is that the Section 7 consultation for federal agencies requires
them to ensure their actions do not destroy or adversely modify critical habitat in addition to not
jeopardizing species.70
After being sued for not designating critical habitat at the time of listing,71 FWS issued a
proposed designation in October 2009,72 with the final designation of critical habitat scheduled to
be completed by June 30, 2010.73 However, because of an incorrect calculation of U.S. territorial
waters, the proposed designation was revised and reissued on May 5, 2010, reducing the proposed
area from 519,403 km2 to 484,764 km2.74 A draft economic analysis of how much the critical
habitat designation is expected to cost was also issued in 2010.75 According to that analysis, the
polar bear habitat designation would have little financial impact on energy development,
primarily because the MMPA already imposes restrictions related to the species, and so those
costs are already part of the process. However, because the listing adds a Section 7 consultation
requirement, the cost is estimated at $53,900 per year.

68 ESA § 4(b)(2), 16 U.S.C. § 1533(b)(2).
69 According to FWS, as of September 21, 2010, it has listed between 1,958 species and 2,028 species, depending on
which FWS website is used, and designated critical habitat for 597 of those species. See FWS websites at

In some cases the agency can determine that the public designation of habitat could put the species in danger, but that is
an exception to the rule of naming the area.

Recovery Plans
A recovery plan provides recovery goals for listed species and is required by the ESA.76 FWS is
required to produce a plan with public input (which may include teams to prepare the plan) that
identifies by specific, measurable criteria when a species has recovered, showing when it can be
removed from listing. A recovery plan is intended to provide for the conservation and survival of
listed species, giving priority to those species most likely to benefit from such a plan,
“particularly those species that are, or may be, in conflict with construction or other development
projects or other forms of economic activity.”77 It would appear the polar bear would be such a
priority.
A recovery plan is one of the areas under the ESA where expense is considered—a recovery plan
must provide estimates of the time and money needed to achieve the plan’s goal.78 FWS and
NMFS are required to report to Congress every two years on recovery plans they have prepared
and the status of the species in those plans. While the MMPA has a reporting requirement in
conjunction with monitoring efforts under the ITAs, there is no similar requirement for
identifying any success in protecting species.
In some instances a recovery plan is issued at the time of the listing. No plan for the polar bear
has been issued. Upon completion of a plan, Congress would receive biennial updates on the
polar bear’s status.
Difference If Listed as Endangered
There would be different protections if the polar bear had been listed as an endangered species,
rather than a threatened one. However, as it was already forbidden to kill, harm, or harass the bear
under the MMPA, an endangered status would not improve that protection. Primarily, the
endangered listing would mean no Special Rule. Without the Special Rule, there would be no
harmonization of the incidental take permission, military exemptions, citizen suits, and
subsistence users, possibly causing confusion as to which law applied. Incidental takes would
require development of HCPs, which would focus more attention on habitat restoration and
protection. Takes of the polar bear would not be limited to actions in Alaska, and takings based on
climate change could be more of a factor in determining harm. Without the Special Rule, there
would be no special standard for military readiness activities. Without the Special Rule, citizen
suits would not be limited in scope beyond what was provided by the ESA. Also, without the
Special Rule, there would not be an exception allowing the killing of polar bears for commercial
sale of handicrafts by subsistence users.
An endangered listing could enhance international protection of the bear. The Convention on
International Trade in Endangered Species of Wild Flora and Fauna (CITES) provides additional
trade protections for those species threatened with extinction, known as Appendix I species. The
polar bear is listed as an Appendix II species, meaning that it does not have all of the protections
76 ESA § 4(f), 16 U.S.C. § 1533(f). Approximately two-thirds of the listed species have such plans. See
http://ecos.fws.gov/tess_public/Boxscore.do.
77 ESA § 4(f)(1)(A), 16 U.S.C. § 1533(f)(1)(A).
78 ESA § 4(f)(1)(B)(iii), 16 U.S.C. § 1533(f)(1)(B)(iii).
Congressional Research Service

available to an Appendix I species. A country cannot unilaterally place a species on either list.
However, the United States’ determination that the polar bear was in danger of extinction would
likely be persuasive in changing the bear’s status from Appendix II to Appendix I, providing the
additional trade protections afforded to Appendix I species.
Congressional Action
Several pieces of legislation have been introduced in the 111th Congress to alter the effects of the
polar bear listing. One bill would eliminate the listing altogether (H.R. 5379), effectively
reinstating the sport-hunt program and nullifying the Special Rule. Other bills, H.R. 1055 and S.
1395, would revise the MMPA to allow continued import of polar bears, regardless of their status.
S. 1395 would further modify the act to allow imports even when they would have a significant
impact on the Canadian population of bears and regardless of whether they were otherwise
consistent with the MMPA. H.R. 1054 would create an exception in the MMPA to allow import of
those bears killed prior to the May 2008 listing.
Conclusion
The polar bear was already protected under the MMPA before FWS listed it as threatened under
the ESA, but some additional protections would inure to the polar bear’s benefit by being covered
by the ESA. Being listed as a threatened species meant permits for importing sport-hunted polar
bear parts from Canada were discontinued—a practice that permitted approximately 80 bears per
year to be imported. The ESA protects the bear and its habitat, meaning that some protection may
accrue if habitat destruction is prosecuted. Critical habitat designation and recovery plans are two
areas in which the ESA provides protection, but the MMPA does not. However, as the critical
habitat designation is still in the draft phase, and no recovery plan is prepared, the potential for
such additional protections remains unaddressed.
Some of the protections the ESA may have added were obviated by the creation of the Special
Rule. For example, the Special Rule ends any difference between incidental takes of polar bears
under the ESA and under the MMPA by declaring that compliance under the MMPA would be
evidence of compliance with the ESA. This could clarify the permitting process by showing only
one permit was required, possibly benefitting current and future permit holders. The Special Rule
allows categories of military activities to be exempted, rather than an action-by-action review as
required under the ESA. The Special Rule limits takes to activities occurring in Alaska, and
allows the MMPA ITA process to control, which could be argued as being less protective of polar
bear habitat. The citizen suit provision was an ESA tool that could be used to halt activities that
harmed the bear, but was limited in scope by the Special Rule. The Special Rule also declares that
the MMPA rules for subsistence users apply, ending any distinction that might have protected the
polar bear had just the ESA been used.
The Omnibus Appropriations Act of 2009 allowed the Secretary of the Interior to “withdraw or
reissue” the Special Rule without having to undergo the rulemaking procedures required by the
APA.79 But the Secretary did not act within the May 2009 deadline, and so the Special Rule

remains in place. If the polar bear’s threatened status is changed, the Special Rule will no longer
apply.
