Gray Wolves Under the Endangered Species Act (ESA): Distinct Population Segments and Experimental Populations - EveryCRSReport.com
November 5, 2007 – November 1, 2011 RL34238
Even before passage of the Endangered Species Act (ESA), federal law protected the wolf, which was nearly eradicated in the lower 48 states by the mid-1900s. Following ESA enactment, the U.S. Fish and Wildlife Service (FWS) placed four gray wolf subspecies—the eastern timber wolf, the Mexican wolf, the Texas gray wolf, and the northern Rocky Mountain wolf—on the first ESA list of endangered species. In 1978, FWS replaced the subspecies listings by listing the gray wolf species (Canis lupus) as endangered in all of the conterminous 48 states except Minnesota, where FWS listed it as threatened. In 2011, FWS found that this listing was in error; that more targeted regional units were appropriate for wolves (notably in the Southwest and Pacific Northwest); that a newly recognized species, the eastern wolf (Canis lycaon), not the gray wolf, occupied the Northeast; and that all or parts of 29 eastern states should be removed from the gray wolf’s historic range.
ESA protection for wolf DPSs has varied since the first DPSs—Western, Eastern, and Southwestern—were proposed in 2003. Each effort by FWS to delist the wolf or designate a DPS has been rejected by a court or settled by the agency. Most recently, the April 2009 rules that had established and then delisted DPSs in the Western Great Lakes and the Northern Rockies were nullified as a result of litigation. As a consequence, the Northern Rockies wolves resumed their Ex Pop status, meaning they were treated as threatened in most circumstances but were endangered outside of the Ex Pop boundaries. Wolves in the rest of the lower 48 states were again endangered, with the exception of Minnesota wolves, which were threatened.

Even before passage of the Endangered Species Act (ESA), federal law protected the wolf, which was nearly eradicated in the lower 48 states by the mid-1900s. Following ESA enactment, the U.S. Fish and Wildlife Service (FWS) placed four gray wolf subspecies—the eastern timber wolf, the Mexican wolf, the Texas gray wolf, and the northern Rocky Mountain wolf—on the first ESA list of endangered species. In 1978, FWS replaced the subspecies listings by listing the gray wolf species (Canis lupus) as endangered in all of the conterminous 48 states except Minnesota, where FWS listed it as threatened. In 2011, FWS found that this listing was in error; that more targeted regional units were appropriate for wolves (notably in the Southwest and Pacific Northwest); that a newly recognized species, the eastern wolf (Canis lycaon), not the gray wolf, occupied the Northeast; and that all or parts of 29 eastern states should be removed from the gray wolf's historic range.
The April 2009 rule for the Northern Rockies was the topic of legislation in April 2011, when Congress took the unusual step of directing FWS to delist an endangered species. Section 1713 of P.L. 112-10 required FWS to reissue the 2009 Northern Rockies DPS rule. FWS's reissuance of that rule on May 5, 2011, ended federal protection of the gray wolf in Montana, Idaho, eastern Washington, eastern Oregon, and north-central Utah, but kept the wolf as a listed species in the remainder of the lower 48 states. Also on May 5, 2011, FWS proposed designating a DPS in the Western Great Lakes area and delisting those gray wolves. On October 5, 2011, FWS proposed delisting the wolves in the Wyoming DPS and terminating the Ex Pop. The proposal is contingent upon the Wyoming legislature's passing certain management requirements.
For centuries, wolf populations have been under pressure by humans. Wolves are carnivores, feeding not only on a variety of animal species smaller than themselves, but also on very large mammals such as bison, elk, and even moose. Wolves are able to prey on large mammals by hunting cooperatively in packs. However, these large species are also favorite game animals for human hunters. In addition to game animals, their prey may include livestock such as cattle and sheep; some people perceive them as a direct threat to humans as well. These habits led to an effort to reduce or eliminate the species. Wolves were eventually eliminated in most states in an effort supported by the science community at the time. But coinciding roughly with the forester Aldo Leopold's essay, "Killing the Wolf," in A Sand County Almanac in 1948, the view that wolves must be eliminated began to change. Leopold wrote the following:
I was young then, and full of trigger-itch; I thought that because fewer wolves meant more deer, that no wolves would mean hunters' paradise. But after seeing the green fire die, I sensed that neither the wolf nor the mountain agreed with such a view.... Since then I have lived to see state after state extirpate its wolves. I have watched the face of many a newly wolfless mountain, and seen the south-facing slopes wrinkle with a maze of new deer trails. I have seen every edible bush and seedling browsed, first to anaemic desuetude, and then to death.
Leopold's somewhat poetic understanding of predator-prey interactions marked the beginning of a new scientific view of the role of predators in ecosystems. Scientists came to agree that, in the absence of major predators, prey populations would expand until some other factor (usually food) limited their population growth. As seen in a variety of ecosystems, the elimination of major predators devastated plant populations and led to serious reductions in the other species depending on those plants for food, nesting, migration habitat, or concealment or in any species dependent on the undisturbed ecosystem. The disappearance of wolves, eagles and other hawks, bears, and other top carnivores in much of their former ranges contributed to the passage of the Endangered Species Act (ESA) in 1973, and ultimately, to the re-introduction of wolves into parts of their former range. And predictably, the conflicts over livestock and game that led to the wolf's near extinction a century ago re-emerged. The ensuing conflicts over wolf management are the topic of this report.
To protect gray wolves under the ESA, there needs to be some agreement on what a gray wolf is scientifically. Like many large mammals, such as bears (Ursus arctos), mountain lions (Felis concolor), and white-tailed deer (Odocoileus virginianus), gray wolves (Canis lupus) have a complicated, even convoluted, taxonomic history. Variations in color, size, and bone structure have led some mammalogists to designate wolves in different areas as different subspecies or populations, whereas other experts would recognize only a single species with variability. A few key terms are central to the taxonomic debate discussed below:
A population is a group of "organisms of the same species that inhabit a specific area."
A species is a "naturally [occurring] population or a group of potentially interbreeding populations that is reproductively isolated (i.e., cannot exchange genetic material) from other such populations or groups."
A subspecies is a "taxonomic category that subdivides species into morphologically distinct groups of individuals representing a step toward the production of a new species, although they are still fully capable of interbreeding. Subspecies are usually geographically isolated."
Taxon, or the plural taxa, is defined as "a grouping of organisms given a formal taxonomic name at any rank: species, genus, family, order, class, division, phylum, or kingdom."1
These terms may appear clear; however, there are no simple measures to draw unequivocal distinctions. Biologists commonly describe their colleagues as lumpers or splitters, based on their inclinations in classifying organisms. As the names suggest, lumpers are those who tend to minimize differences, and see one or a few species, perhaps with some variations, while splitters tend to emphasize those differences, dividing a species into many subspecies, or populations. As one well-known mammalogist once stated, "Splitters make very small units—their opponents say that if they can tell two animals apart, they place them in different genera, and if they cannot tell them apart, they place them in different species. Lumpers make large units—their opponents say that if a carnivore is neither a dog nor a bear they call it a cat."2
For wolves, which are (or were) found in temperate and polar areas throughout the Northern Hemisphere, some observers (splitters) would argue that there are as many as 24 subspecies in North America and 8 in Europe and Asia.3 More recently, lumpers have had the upper hand in the scientific community. However, that tide may be changing. In May 2011, the U.S. Fish and Wildlife Service (FWS) proposed recognizing a third species of wolf, the eastern wolf (Canis lycaon), in addition to the gray and red wolf.4 (See "2011 Regulatory and Legislative Activity" below, for more on this announcement.)
This muddled state of taxonomic affairs is entirely predictable for several reasons. First, wolves are extremely wide-ranging, both as a species and as individuals, so occasional interbreeding among them could certainly confuse the picture. Second, the consistency of variations over time is hard to determine, since long-range studies of long-lived species are rare. Third, evolutionary change does not stop, and wolves are an adaptable species, as shown by their behavior and by their presence in a tremendous variety of ecosystems.5 The debate among academic scientists also has an air of informed judgment—and there is no reason to predict that the scientific debate will end any time soon.
The Endangered Species Act6 (ESA or the Act) provides for the protection and conservation of species that the FWS or the National Marine Fisheries Service identifies as threatened or endangered.7
Under the ESA, if FWS determines that the best scientific information available indicates that a species is in danger of becoming extinct throughout all or a significant portion of its range, FWS lists the species as endangered.8 If FWS determines that a species is likely to become endangered within the foreseeable future, FWS lists the species as threatened.9 If the scientific bases underlying a listing change, FWS may take three steps: delist the species, thereby removing it from ESA protection; downlist it, decreasing its protection level from endangered to threatened; or uplist it, increasing its protection level from threatened to endangered.
ESA amendments further allow FWS to list distinct population segments (DPS) within vertebrate species for protection. FWS may also reintroduce experimental populations (Ex Pops) to areas that the species no longer occupies within it historic range.10
The ESA prohibits taking endangered wildlife,11 which means it is illegal to harass, harm, or kill such species.12 FWS regulations prohibit taking a threatened species unless special rules are in place.13 Special rules may be issued for DPSs listed as threatened and Ex Pops. FWS may issue Section 4(d) rules or special rules to provide customized protection that FWS deems necessary and advisable for the species' conservation.14 Under special rules, taking species, including killing them, may be allowed. The special rules are promulgated in Title 50 (Part 17) of the Code of Federal Regulations.
The ESA requires FWS to develop a recovery plan for listed species15 that will include a description of necessary management actions, measurable criteria for when a species can be delisted, and estimated costs to achieve this goal.
In 1982, Congress modified the ESA to allow reintroducing Ex Pops of listed species "outside the current range of such species if the Secretary determines that such release will further the conservation of the species."16 Congress intended Ex Pops as a way to expand current ranges of listed species without imposing severe restrictions of private and public land. The practice allows introduction of a species outside its current range to restore it to its historic range.
Two criteria must be met to establish an experimental population under the law. First, the Department of the Interior (DOI) must authorize the release of the population. Second, the population must be "wholly separate geographically from nonexperimental populations of the species."17 Congress required the separation so that the introduced population could be clearly distinguished from existing populations of the species.
Under the ESA, members of an Ex Pop generally are treated as threatened,18 and are eligible for special rules.19 A congressional committee referred to special rules as a way to reduce public opposition to the release of Ex Pops of predators such as wolves:
The committee fully expects that there will be instances where the regulations allow for the incidental take of experimental populations.... The committee also expects that, where appropriate, the regulations could allow for the directed taking of experimental populations. For example, the release of experimental populations of predators, such as red wolves, could allow for the taking of these animals if depredations occur or if the release of these populations will continue to be frustrated by public opposition.20
Section 10(j)(2)(B) of the ESA requires FWS to determine whether the Ex Pop is essential to the continued existence of an endangered or threatened species, otherwise the Ex Pop is deemed nonessential. Currently, there are no essential experimental populations. Critical habitat is not designated for nonessential Ex Pops.
Examples of species with nonessential experimental populations are the Colorado pikeminnow (or squawfish), the southern sea otter, the gray wolf (in the Southwest, central Idaho, and Yellowstone areas), the black-footed ferret, and the whooping crane.
The ESA definition of species has changed since the law's enactment. In 1973 the definition included "any subspecies of fish or wildlife or plants and any other group of fish or wildlife of the same species or smaller taxa in common spatial arrangement that interbreed when mature."21 In 1978 Congress amended that definition to include the term distinct population segment (DPS), which was limited to vertebrates.22 The change was controversial.
The General Accounting Office (GAO) (now the Government Accountability Office) recommended limiting the definition of species to higher taxonomic categories than populations, and excluding all distinct populations, including geographically separated populations.23 GAO proposed the following definition: "The term 'species' includes any subspecies of fish, wildlife, or plants."24
Congress did not follow the GAO recommendation. It agreed with FWS that the service needed to be able to adopt different management practices for different populations, based on need. A Senate committee report discussing populations said, "the committee agrees that there may be instances in which FWS should provide for different levels of protection for populations of the same species," but advised that the practice be used "sparingly and only when the biological evidence indicates that such action is warranted."25
Thus, Congress revised and limited the definition of species in 1978 by eliminating taxonomic categories below subspecies from the definition, except for vertebrates.26 The revised, and still current, definition is "any subspecies of fish or wildlife or plants, and any distinct population segment of any species of vertebrate fish or wildlife which interbreeds when mature."27 However, the phrase distinct population segment had no meaning in the scientific community outside of the ESA, and was not used in ESA listings by FWS for nearly two decades.
A DPS refers generally to a portion of a listed species that is separated from the rest of the species by genetic distinction and range. The legislative history offers two examples of when the same species should have different protection: (1) when a U.S. population of an animal is near extinction even though another population outside the United States is more abundant; and (2) where conclusive data have been available only for certain populations of a species and not for the species as a whole.28
In 1996 FWS introduced its DPS policy (hereinafter referred to as "the Policy").29 The Policy contains the criteria that must be met for a species to be protected at the population level. First, the population segment must be discrete. Factors considered to determine discreteness are whether the segment is "markedly separated from other populations of the same taxon as a consequence of physical, physiological, ecological, or behavioral factors."30 Discreteness can also be found if the population is delimited by international governmental boundaries. Although state boundaries are frequently used to describe a DPS, they cannot be used under the Policy to determine discreteness.
Next, the population segment must be found to be significant, meaning its demise would be an important loss of genetic diversity.31 Four factors are listed in the Policy for determining a species' significance: (1) persistence of the segment in an ecological setting unusual or unique for the taxon; (2) evidence that loss of the DPS would result in a significant gap in the range of the taxon; (3) evidence that the DPS represents the only surviving natural occurrence of a taxon within its historic range; or (4) evidence that the DPS differs markedly from other populations of the species in its genetic characteristics. Genetic evidence may be considered but is not required. The Policy indicates that "available scientific evidence of the discrete population segment's importance" will be considered in finding significance, but does not specify the best available scientific evidence.
If a species is found to be both discrete and significant, then its status is reviewed to see whether it is endangered or threatened. The same criteria are used for a DPS listing as for any other listing. The determination must be based solely on the "best scientific and commercial data available."32
According to the Policy, agency efficiency and focus were two intended benefits of DPSs. The Policy said determining DPSs will "concentrate ... efforts toward the conservation of biological resources at risk of extinction."33 The Policy suggested the practice of using DPSs could help endangered species by focusing on smaller groups:
This may allow protection and recovery of declining organisms in a more timely and less costly manner, and on a smaller scale than the more costly and extensive efforts that might be needed to recover an entire species or subspecies. The Services' [FWS & the National Marine Fisheries Service's] ability to address local issues (without the need to list, recover, and consult rangewide) will result in a more effective program.34
FWS has followed Congress's admonition to apply the practice "sparingly." According to the most recent list compiled by FWS, only 47 of the 375 vertebrates within the United States listed under the ESA are DPSs.35
In six cases, the listing classification of DPSs appears to be used solely to remove animals from protected status. The DPS designation and the delisting occurred on the same day in the same Federal Register notice. Four instances are for gray wolf DPSs. The only designation and delisting that remained in place (the Columbian white-tailed deer) was the one not challenged in court. The six DPS designations are the following:
Columbian white-tailed deer, Douglas Co. DPS—July 24, 2003
Gray wolf, Western Great Lakes DPS—February 8, 200736
Grizzly bear, Yellowstone DPS—March 29, 200737
Gray wolf, Northern Rocky Mountain DPS—February 28, 200838
Gray wolf, Western Great Lakes DPS—April 2, 200939
Gray wolf, Northern Rocky Mountain DPS—April 2, 2009.40
Some have criticized using DPSs to remove ESA protections from certain segments of a listed species rather than using it to protect species. The district court reviewing a challenge to the 2007 Western Great Lakes DPS designation and delisting suggested that this practice was contrary to the ESA.41 The court said the ESA did not unambiguously allow a species to be designated as a DPS at the same time it was delisted, noting that a goal of the Act was to protect species. The court vacated the designation and the delisting, and remanded the matter to FWS.
In other examples, the species has become downlisted (having its status dropped from endangered to threatened) the same day as being designated a DPS:
Gray wolf, Western DPS—downlisted April 1, 2003
Gray wolf, Eastern DPS—downlisted April 1, 2003.
However, for many more species, the designation of a DPS increased its protection status, by protecting a group, even though the species as a whole was not covered by the Act. Examples of DPS designations resulting in more protection follow:
California bighorn sheep, Sierra Nevada DPS—listed as endangered January 3, 2000
Canada lynx, contiguous U.S. DPS—listed as threatened March 24, 2000
Atlantic salmon, Gulf of Maine DPS—listed as endangered November 17, 2000
Dusky gopher frog, Mississippi DPS—listed as endangered December 4, 2001
Pygmy rabbit, Columbia Basin DPS—listed as endangered March 5, 2003
California tiger salamander, Sonoma County DPS—listed as endangered March 19, 2003
Northern sea otter, Southwest Alaska DPS—listed as threatened August 9, 2005.
A DPS is treated like a species under the Act; therefore, special rules may also be created for threatened DPSs.
The history of gray wolf protection is interconnected with the history of the ESA. Wolf protection began at the nascency of the ESA, when it was one of the first mammals covered under the precursor to the ESA, the Endangered Species Preservation Act of 1966.42
At the start, the ESA protected four subspecies of gray wolf: the Mexican wolf, the northern Rocky Mountain wolf, the eastern timber wolf, and the Texas gray wolf.43 In 1978, the gray wolf was relisted at the species level as endangered throughout the lower 48 states, except for Minnesota, where it was listed as threatened.44 As a result of regulatory listings and court nullifications described below, wolves in the United States have been listed in all of the available categories for a vertebrate species: (1) never listed (Alaska); (2) delisted (in certain DPSs); (3) experimental populations (Southwest; Yellowstone and Central Idaho); (4) threatened (Minnesota); and (5) endangered (every wolf in the lower 48 states that was not in a DPS, experimental population, or in Minnesota).
Consistent with the ESA requirement of developing recovery plans for listed species, FWS developed recovery plans for the gray wolf based on its early listing at the subspecies level—the eastern timber wolf, the Mexican wolf, and the northern Rocky Mountain wolf. The eastern timber wolf recovery plan was issued in 1978, and revised in 1992.45 The recovery goals were two-fold: the population in Minnesota must be stable or growing; and a second population of at least 100 wolves must be sustained for at least five years. If that population was isolated from the Minnesota population, a population of at least 200 wolves was required.
In 1982, FWS completed the recovery plan for the Mexican wolf.46 The recovery goal was a viable and self-sustaining population of at least 100 wolves in a 5,000 square mile area within the Mexican wolf's historic range.
FWS prepared a recovery plan for the gray wolf in the Northern Rocky Mountains in 1987.47 However, the 1987 recovery goal was later deemed insufficient. It was modified through scientific inquiry and peer review in 1994 and reaffirmed in 2002.48 The Northern Rocky Mountain recovery goal is a connected three-state wolf population that never goes below 30 breeding pairs and 300 wolves. Connectivity is a key part of population recovery, as it ensures adequate genetic exchange for the long-term viability of the species. When wolves are delisted and state management fully replaces federal management, FWS has determined that the recovery goal is being maintained when each state (Montana, Idaho, and Wyoming) maintains at least 15 breeding pairs and 150 wolves.49
Despite near-eradication of the wolf in the lower 48 states, some suitable habitat in the wolf's historic range survived, though in a highly modified form. At the end of the 20th century, FWS planned to reintroduce the wolf to parts of its historic range, using the Ex Pop provisions of the ESA.
No reintroduction was more controversial than that in the greater Yellowstone ecosystem, where all other large vertebrates were still present, and where many scientists agreed that elk populations—a favorite wolf prey—had reached harmful levels. In 1995 and 1996 FWS released 66 gray wolves from Canada in Yellowstone and central Idaho. (See Figure 1 and Figure 2.)
When wolves were returned, the science community was greatly interested in the potential effects from a first-ever return of a major predator to a nearly intact ecosystem. The interest was intense partly because the Yellowstone area was already well studied, with long-term data on many species, including both competitors (e.g., coyotes and, to some extent, grizzlies) and potential prey (e.g., elk, moose, and bison). As scientists had expected, wolves had a profound effect on elk, but there is also evidence of effects that were less predictable—on aspens, cottonwoods, beavers, beetles, mice, red foxes, ravens, and voles, among others.50 However, the reintroduction of wolves to Yellowstone was, and still is, fraught with controversy.

While the Northern Rockies gray wolf recovery plan acknowledged that recovery of the species could require reintroducing it into the area around Yellowstone National Park, the decision to do so was controversial. Suit was filed to compel FWS to reintroduce wolves to Yellowstone. However, in 1992, the court ruled that it could not compel FWS to act when Congress had blocked funding for the reintroduction.51
In another suit, a man charged with killing a wolf from the Yellowstone Ex Pop challenged the scope of the reintroduction. He argued that he had killed a Canada wolf, which was not a protected species. This argument failed. The Ninth Circuit upheld the regulations for the experimental population, holding that once the wolves from Canada were introduced into the park, they became protected under the ESA.52
Another lawsuit argued that because the Yellowstone Ex Pop may interact and breed with the few lone wolves in the area,53 the Ex Pop designation violated the ESA Section 10(j) requirement that experimental populations be "wholly separate geographically from nonexperimental populations of the same species."54 The district court ruled that the Yellowstone population would have to be removed, but was overruled by the Tenth Circuit Court of Appeals.55 The appellate court rejected the argument that the legislative history of Ex Pops meant that the experimental population must be separate from every naturally occurring individual animal. The court deferred to the DOI management plan for the reintroduction, finding that it did not conflict with the statute.
Another claim disputed FWS management of the wolves. A rancher argued the agency failed to control wolves that were preying on livestock. After FWS killed three wolves, including the lead male wolf of the offending pack, no more depredations were found. The court dismissed the claims on procedural grounds.56
The District Court of Montana is considering whether Ex Pops in Yellowstone and central Idaho no longer fit the statutory definition of an Ex Pop because they are no longer geographically isolated. The court has suggested that their Ex Pop status would end without further regulatory action.57 If this is upheld, the wolves in that Ex Pop (which consists only of Wyoming wolves as of May 5, 2011) would become part of the lower 48 states' general population and be classified as endangered.
FWS has argued in its brief to the court that an Ex Pop designation can be removed only through rulemaking or other regulatory action. Other defendant-intervenors have taken the same position. In its brief, Safari Club International, a defendant-intervenor, suggested that if the court is right, it would have a chilling effect on the Ex Pop program. Deregulation of Ex Pops should occur only when the species is no longer endangered, according to Safari Club International, otherwise reintroduction of Ex Pops ultimately would lead to larger territories occupied by endangered species, and would be a disincentive for states, tribes, and other parties to accept Ex Pops on their land. The plaintiffs argued that the ESA's definition of Ex Pop58 prohibits FWS from managing a species as experimental once it is no longer wholly separate geographically from other populations. FWS has also filed a motion to have the action dismissed, in light of the reissuance of the 2009 rule as required by P.L. 112-10, §1713. If granted, the questions raised by the District Court of Montana would remain unanswered.
Wolves also had been extirpated in the Southwest. FWS recognized a separate subspecies, the Mexican wolf (Canis lupus baileyi), which was found in very low numbers in Mexico. After a cooperative and successful captive breeding program of wolves obtained from Mexico, reintroduction was begun in 1998, in an area centered in the Apache National Forest in Arizona and the Gila National Forest in New Mexico. In February 2010 FWS announced that the population of Mexican gray wolves totaled 42, the lowest since 2002.59 It was a drop from the previous year's total of 52, according to the agency. In January 2011 the population totaled 50.60
Reintroduction of the wolf to the Southwest was no less controversial than that in the Northern Rockies. Ranchers sued, claiming the action violated the National Environmental Policy Act (NEPA), as well as the ESA. The District Court of New Mexico found for FWS, even though livestock owners and FWS had different estimates as to the impact of the wolves on domesticated stock.61
Even after the Southwest wolf reintroduction, the area remains a center of intense public controversy. Environmentalists sued FWS for not acting to modify the reintroduction regulations.62 The action was dismissed as moot. A different suit brought by ranchers argued that the reintroduction violated the ESA and NEPA in part because the wolves were hybrids. The suit was dismissed.63 In 2010 the Center for Biological Diversity filed suit to force the listing of the Mexican gray wolf as either an endangered species or a DPS.64 The suit was settled as part of a multi-species settlement agreement reached with FWS in July 2011.65 FWS agreed to make a listing decision (or a determination that listing was not warranted) by the end of FY2012,66 provided that funding for the listing program remained substantially the same as in FY2011.67 If the Mexican gray wolf is listed as endangered, either as a species or a DPS, the Ex Pop status of the Mexican gray wolf would end, as would the exceptions that allow takes of those wolves.
The gray wolf was originally listed at the species level as threatened in Minnesota, and endangered in the remainder of the lower 48 states. Since the issuance of the DPS Policy, FWS has pursued dividing the gray wolf into DPSs.68 DPSs supplant Ex Pops, but when a DPS has been nullified, FWS returns the population to its Ex Pop status. All DPS designations were challenged in federal court, and each court rejected FWS's action, leading to each rule being withdrawn.
In 2003, FWS divided gray wolves into three DPSs, Western, Eastern and Southwestern, and downlisted the Eastern and Western DPSs from endangered to threatened.69 At the same time, FWS removed gray wolves from ESA protection in all or parts of 16 southern and eastern states where they did not occur historically. Wolves in the Southwest remained listed as endangered.
The 2003 rule was challenged in two federal district courts. The plaintiffs before the District Court of Oregon disputed how the DPS ranges were designated. They argued that FWS considered only where the wolves were currently located when determining their viability. This allowed FWS to count wolves only in the areas they occupied. Despite finding that areas outside of the wolves' current range were suitable habitat, although no wolves were present, FWS did not include those areas in defining the DPS ranges. The plaintiffs argued that this method was contrary to the ESA and prior case law, because the Act requires that a species is endangered if it is at risk of extinction in "all or a significant portion of its range." In 2005, the court agreed that FWS had violated the ESA by equating the wolves' current range with a significant portion of its range.70 The court vacated the rule, effectively eliminating the three DPSs and reinstating their protected status.
The other suit was before the District Court for Vermont, which issued a decision eight months after the Oregon court. The plaintiffs in Vermont challenged the rule's final designation of one Eastern DPS, when two DPSs had been proposed for that area: a Northeast DPS and a Western Great Lakes DPS. In 2005, the court found procedural flaws and also that FWS failed to consider significant portion of its range in a way consistent with the ESA.71 The court criticized FWS's method before vacating the rule: "The FWS simply cannot downlist or delist an area that it previously determined warrants an endangered listing because it 'lumps together' a core population with a low to non-existent population outside of the core area."72
After the 2003 DPS rulemaking was nullified in 2005, FWS proposed two other gray wolf DPSs: Northern Rocky Mountain and Western Great Lakes.73 In 2007, the Western Great Lakes gray wolf population was declared a DPS and delisted in the same notice.74 On the same date as the Western Great Lakes rule was issued, FWS proposed designating a Northern Rocky Mountain gray wolf DPS and delisting its population (see Figure 3), except for the Wyoming population because Wyoming's state laws were found to provide insufficient protection for the wolf.75 In the 2008 final rule, FWS designated and delisted Northern Rocky Mountain DPS, including Wyoming.76
In September 2008, the District Court for the District of Columbia vacated the final rule that designated and delisted the Western Great Lakes DPS.77 Unlike the holding in the Northern Rockies DPS case (below), this decision focused on the procedure, not the science, behind the rule. The plaintiffs claimed that FWS had violated the Act by issuing the designation and delisting simultaneously, while FWS argued that the plain meaning of the ESA supported its process. However, in light of the Act's purpose in conserving species, the court found the ESA was ambiguous as to whether FWS could delist a healthy sub-population in this way. The court remanded the action to the agency to find a "reasonable explanation" for its interpretation that the ESA supports a designate and delist rule.78 Instead, in December 2008, FWS reinstated the wolves in the area as either threatened (in Minnesota) or endangered.79
In July 2008, the District Court for the District of Montana issued a preliminary injunction halting the effectiveness of the FWS delisting of the Northern Rockies DPS.80 The delisting had found that Wyoming, Idaho, and Montana had adequate wildlife management programs to support populations above recovery levels.81 However, the court rejected FWS's contention that there was genetic exchange between the Yellowstone experimental population and other packs in the Northern Rockies. (Figure 3 shows the distribution of wolf packs in the two areas in 2008.) Without sufficient genetic exchange, the isolated wolf populations would not be genetically diverse enough to avoid inbreeding, and therefore could not be termed recovered. The court also found that the states' management plans did not seem adequate to support wolf recovery levels. The order reinstated the wolf as endangered until final disposition. In September 2008 FWS voluntarily moved to withdraw the rule.82 Wolves in that area returned to being nonessential experimental populations with special regulations allowing takes.83 (See below at "Section 4(d) Rules for Gray Wolves.")

Note: This distribution of territories can be expected to change over time.
In April 2009, FWS designated wolves in the Western Great Lakes and the Northern Rockies as DPSs and delisted them.84 Once again, an exception was made for the wolves of Wyoming. The Wyoming population was not delisted because FWS found that Wyoming's regulatory framework would not maintain the targeted population goals to ensure genetic health for a viable population in the foreseeable future.85
Suit was filed regarding the Western Great Lakes delisting, and was settled in September 2009.86 FWS withdrew the 2009 rule and reinstated the gray wolf as endangered throughout most of the area and as threatened in Minnesota.87
In August 2010, the District Court of Montana declared the April 2009 Northern Rocky Mountain rule invalid.88 The court held that segregating the Wyoming wolves from the rest of the Northern Rockies DPS violated the ESA by creating a regulatory taxonomic category not allowed by the Act. The ESA does not allow listing (or delisting) part of a DPS, such as wolves in Wyoming, according to the court.89 The wolves were returned to their status as an experimental population and again treated as threatened.90
The State of Wyoming sued FWS for finding its regulatory plan did not meet recovery goals for the wolf. In November 2010, the District Court for Wyoming held that FWS had acted arbitrarily and capriciously by requiring the Wyoming plan to designate all of the state as trophy-game area, meaning a permit would be required to kill a wolf.91 Instead, the state plan designated approximately 90% of the state as predator areas (not including National Parks), meaning no permit was required to kill a wolf. The Wyoming plan also required the state to maintain no fewer than seven packs outside of National Parks. The court remanded to FWS to see if the Wyoming plan met the federal recovery goals of 15 packs statewide, as well as genetic diversity.
A lawsuit filed on behalf of Washington cattle ranchers claimed FWS has failed to conduct five-year reviews of the gray wolf as required under Section 1533(c)(2).92 On May 5, 2011, FWS announced it would conduct a status review of the gray wolf.93 The parties settled, agreeing that FWS would complete its five-year status review by February 29, 2012.94
Conditional Settlement Reached and Then Halted
In March 2011 FWS announced it had reached a settlement agreement with many of the plaintiffs that had challenged the 2009 Northern Rocky Mountain DPS rule.95 However, the District Court of Montana rejected a motion needed to implement the agreement,96 and legislation by the 112th Congress mooted its necessity. (See "Legislation Directing Delisting of the Northern Rocky Mountain DPS" below.) However, even if enacted, the agreement would not have marked the end of litigation in the area: four plaintiffs refused to participate in the agreement, and, of the defendant-intervenors, only Montana indicated it supported the action.97
The agreement depended on the District Court of Montana partially revoking the stay put in place while its August 2010 decision was appealed,98 thus allowing Idaho and Montana to resume management of wolves in their state pursuant to plans approved by the FWS. The court held that it lacked authority to take that step because doing so would allow a protected species to be killed in violation of the ESA. If the settlement had been implemented, both Montana and Idaho could allow killing wolves, even though under the ESA, those wolves were protected species. In addition to lacking legal authority, the court also found that revoking the stay would violate notions of equity. The non-settling plaintiffs and the defendant-intervenors who had not signed on to the agreement would not be able to continue their legal challenges.
The court noted weaknesses in the agreement. In addition to binding non-settling plaintiffs to a conclusion they opposed, the court found that although FWS had agreed to withdraw its Solicitor's Opinion regarding the meaning of significant portion of its range,99 it had not agreed to issue a new opinion.100 Also, the additional monitoring FWS would perform under the agreement would not take place for three years, leaving the status of the wolf unknown during that time.
The Northern Rocky Mountain DPS and the Western Great Lakes DPS have charted parallel regulatory courses, and both populations have grown over the past two decades. However, data show that in terms of wolves per square mile, wolf density is much greater in the Western Great Lakes than in the Northern Rocky Mountains. Despite this, Congress has introduced more bills targeting delisting Northern Rocky Mountain wolves than those in the Great Lakes area, including the bill enacted as P.L. 112-10.

Note: The DPSs shown in this map were nullified, although the Northern Rocky Mountain DPS was reinstated as directed by P.L. 112-10, §1713. Maps of wolf pack territories for the Western Great Lakes and the Blue Range are not available. BRWRA is an abbreviation for Blue Range Wolf Recovery Area.
CRS calculated the areas shown as "Core Wolf Populations" in Figure 4, based upon data provided by FWS and Montana Fish, Wildlife and Parks. These data showed that the Core Wolf Population area in the Western Great Lakes is approximately 78,775 sq. miles and the Northern Rocky Mountains Core Wolf Population area is about 134,697 sq. miles. Based on 2010 wolf populations, the Western Great Lakes has 4,169 wolves in 78,775 sq. miles, or approximately 53 wolves per 1,000 sq. miles. The Northern Rocky Mountains DPS has 1,651 wolves in about 134,697 sq. miles, making for a less dense population of 12 wolves per 1,000 sq. miles.
Following successive court orders invalidating FWS's delisting rules, and in light of increasing populations of wolves in some parts of the country, the 111th Congress began to consider legislative options to exclude the wolf from the protections of the ESA. The 112th Congress passed the first law to delist a species. The Full-Year Appropriations Act of 2011, P.L. 112-10, §1713, directs FWS to delist the gray wolf in Montana, Idaho, eastern Washington, eastern Oregon, and north-central Utah, but leaves the wolves in the remaining lower 48 states federally protected as either threatened or endangered. Enactment of P.L. 112-10, §1713 was significant because legislation to delist species rarely had been proposed and never had been successful.101
Some have argued that P.L. 112-10 is a tipping point in species protection—that politics and not science will dictate species protection in the future. However, Section 1713 is not a blanket delisting, but a direction to re-release the April 2009 rule in which FWS determined that the best available science supported delisting those wolves. As referenced above, however, a federal court found FWS had violated the ESA in making this determination.102 P.L. 112-10 bars judicial review of the rule, but still allows regulatory actions, such as delisting in Wyoming, or relisting of the DPS, should the wolf's status change. Section 1713 states that it does not alter the November 2010 Wyoming District Court ruling that remanded Wyoming's management plan to FWS. FWS reissued the 2009 rule on May 5, 2011.103
A challenge to Section 1713 argued that it violated the Separation of Powers Doctrine under the Constitution by trying "to affect the outcome of a case, without amending the underlying statute."104 The District Court of Montana rejected the claim,105 and an appeal is pending.
Other bills still pending in the 112th Congress would restrict federal protection of the gray wolf. Those addressing the wolves of the West may not be advanced in light of P.L. 112-10. For example, Congress apparently chose P.L. 112-10, §1713 over the nearly identical version in S. 321 (Baucus), which would have given the 2009 rule the force of law rather than regulation. Additionally, H.R. 510 (Rehberg), which allows state regulation of wolves in Idaho and Montana, appears mooted by that law.
Other bills do not appear moot. For example, H.R. 838 (Kline) would eliminate federal protection of wolves in the Western Great Lakes area, proposing: "Any wolf in Minnesota, Wisconsin, or Michigan shall not be treated under any status of the Endangered Species Act of 1973 (16 U.S.C. §§1531 et seq.), including as an endangered species, a threatened species, an essential experimental population, or a nonessential experimental population."106 H.R. 509 (Rehberg) and S. 249 (Hatch) would amend the ESA so the Act would not apply to the gray wolf. Those two bills would affect all gray wolves, including the populations in the Southwest as well as the Western Great Lakes and Northern Rocky Mountain areas.
After the delisting directed by P.L. 112-10 went into effect, Representative Candice S. Miller introduced H.R. 1819 which would give states management authority over wolves provided that specified population levels were maintained. H.R. 1819 addresses all three gray wolf107 population centers, the Northern Rockies, the Western Great Lakes, and the Southwest. For each population, if the numbers of wolves dip below a statutorily protected amount, the Secretary of the Interior would be authorized to treat wolves as protected for at least two years after reestablishing the targeted number of wolves. Under H.R. 1819, population goals would not be based on breeding pairs but on individuals. This criterion is not as clearly related to adequate genetic diversity and reproductive capacity, and arguably might be more difficult to measure than the number of breeding pairs.108
The proposed Department of the Interior, Environment, and Related Agencies Appropriations Act for FY2012 (H.R. 2584) addresses gray wolf delistings. Section 119 of that bill would prohibit judicial challenge of any FWS final rule delisting a wolf population in Wyoming or within the Western Great Lakes area if "such State has entered into an agreement with the Secretary of the Interior that authorizes the State to manage gray wolves in that State."
On May 5, 2011, in addition to reissuing the Northern Rocky Mountain DPS rule, FWS proposed changes to gray wolf protection. FWS proposed to do the following: designate the Western Great Lakes as a DPS and delist that DPS; revise the gray wolves' historic range by eliminating parts or all of 29 eastern states; initiate a five-year review for the gray wolf; initiate a status review of the gray wolf in the Pacific Northwest; initiate a status review of the Mexican wolf in the Southwest and Mexico; and recognize a new species of wolf, the eastern wolf (Canis lycaon).109 Some of the proposed actions could lead to further differentiated protection of wolves depending on location. Wolf protection under the proposed rule would be as shown in Figure 5. Almost two months after the comment period for the proposed rulemaking was closed, FWS reopened it for additional comment on the eastern wolf and revision of the historic range.110
Source: Congressional Research Service, compiled from FWS data.
The Eastern DPS designation of the gray wolf was rejected by courts in 2005 and has not been proposed by FWS since then. However, FWS proposed recognizing a new species of wolf, the eastern wolf (Canis lycaon), using newer methodology in distinguishing among species, which relies in part on DNA.111 The proposed eastern wolves' historic range would include portions of eastern Canada, the Western Great Lakes, and the northeastern United States.
From a scientific point of view, designating wolves found in the eastern United States as a separate species is not assured. For example, the encyclopedic Mammal Species of the World discusses the validity of Canis lycaon as a distinct species and concludes that evidence for separation is equivocal.112 However, it does not currently consider this wolf in the East to be a distinct species. Moreover, the North American consortium of national professionals who manage the Integrated Taxonomic Information System (ITIS, the source considered authoritative on taxonomy and taxonomic validity in the United States and its territories, Mexico, and Canada) currently considers this wolf as a subspecies (Canis lupus lycaon).113 The validity debate considers evidence related to mitochondrial DNA, morphology, evidence of hybridization with coyotes, the natural variability of widely distributed species, and the extremely low population densities that make conclusive evidence difficult to obtain.
Designating a new wolf species is likely to be controversial. Based on the results of the status review, petitions to list the species could be filed. However, lawsuits are unlikely until a listing determination is made, or a DPS designated. Subspecies designation has been controversial in other cases, but typically it is FWS resisting the change, not making it. For example, multiple petitions have been filed to designate two subspecies of the greater sage grouse, with FWS ultimately rejecting those petitions, finding the science did not support the distinctions.114 Legal challenges to the science behind the subspecies classifications or DPS designations are not uncommon and can be successful.115 However, they are fact-specific cases in which the court's view of the agency's scientific basis determines the outcome of the case.
The agency is initiating a review of the eastern wolves' status, which could result in listing the eastern wolf under the ESA, either on the FWS's initiative or by petition. Given its status as a proposed new species, the eastern wolf is not protected under the Act, although gray wolves in the eastern half of the United States are listed as threatened (if in Minnesota) or endangered.116 If made final, the effect of the scientific reclassification would be delisting wolves that currently enjoy ESA protection.
Listing the eastern wolf as a separate species could affect gray wolf protection, even if the gray wolf is delisted by then. The eastern wolf could be found to be endangered—no breeding pairs of eastern wolves are reported outside of the Western Great Lakes area, yet it is expected to have a broad historic range. Then, despite the proposed rule to delist the Western Great Lakes DPS, eastern wolf protection could mean the gray wolf in the Western Great Lakes area might be protected under the ESA provision safeguarding species with similar appearances to listed species.117 After all, FWS only recently determined a distinction between the gray and eastern wolf species, and that distinction requires a DNA test.
In addition to the five-year status review for the gray wolf, and the review of the proposed eastern wolf, FWS proposes two other status reviews in the May 5 notice. FWS plans to consider populations in the Pacific Northwest and the Southwest. These reviews could find wolves in those areas should be appropriately designated as DPSs. Gray wolf protections could be altered population by population. This would be consistent with FWS's statement that it intends to replace the 48-state listing with "more targeted regional units."118
It is unclear what effect the proposed removal of most of 29 states from the historic range119 of the gray wolf may have on the animal's protection. However, taken in context with FWS's interpretation of significant portion of its range within the May 5 proposed rulemaking,120 which is discussed below, it could lead to more delisting. When FWS reopened the comment period for this proposed rulemaking, it stated that this revision might be done in two final rules based on geography: Northeast and Southeast.121
A species is listed under the ESA depending on its presence in its range.122 However, despite having an enormous range across the continent of North America, the gray wolf has always had different protection status based on its location—for example, the gray wolf has never been protected in Alaska. The FWS website for the gray wolf shows how the listing status varies based on population location.123 In contrast, the listing for the tiger shows it is protected "wherever found," and the polar bear is listed throughout its entire range.124 As discussed earlier in this report, the gray wolf's history is one of designating and delisting DPSs. Eliminating such a great area from the wolves' range could lead to a finding that in its (now much smaller) historic range wolves have a proportionally larger population—perhaps leading to a finding that wolf populations have recovered there. Thus, it could lead to a finding that gray wolves need less protection in the West. Another possibility is that it could lead to a finding that no protection of gray wolves is necessary in the eastern 29 states as FWS has stated that no such population ever existed there.
FWS's interpretation of significant portion of its range, announced May 5, 2011, to support its proposed delisting of the Western Great Lakes DPS, appears to support these theories. For the proposed rulemaking, FWS stated that a portion of a species' range is significant if it meets two criteria: (1) it is part of the current range of the species; and (2) it is important to the species' conservation "because it contributes meaningfully to the representation, resiliency, or redundancy of the species."125
It could be argued that the focus on a species' current range artificially limits the scope of the ESA listing process. Under that theory, a species is important only where it exists today. Courts rejected a seemingly identical interpretation when it was used in the 2003 designation and revised listing of the Western, Eastern, and Southern DPSs, discussed above.126 The interpretation essentially eliminates consideration of a species' historic range and restricts the review of a species' health to where it is now present. It could skew the listing process, eliminating consideration of areas where a species once was abundant but now is extirpated.
The second criteria of FWS's May 5 interpretation—that the area contributes meaningfully to the species—further limits the area being considered, and so does not appear to avoid this conflict with court precedent.
Additionally, FWS's interpretation appears to conflict with other portions of the Act, which require consideration of a broader area than a species' current range. Under FWS's interpretation, it would be possible to establish critical habitat of a species in an area that FWS says is not part of its range. ESA defines critical habitat to include areas not just currently occupied by the species at the time of listing, but also "specific areas outside the geographical area occupied by the species at the time it is listed ... upon a determination by the Secretary that such areas are essential for the conservation of the species."127
The interpretation also may be seen as inconsistent with the statutory requirement that listing be based in part on the "present or threatened destruction, modification, or curtailment of its habitat or range."128 If a species has already been chased out of damaged habitat, evaluation of its presence in only its current range may seem to restrict consideration of this factor.
On October 5, 2011, FWS published a notice of proposed rulemaking to end federal protection of the gray wolf in Wyoming under the ESA. Wolves would continue to be protected from taking in two national parks and a national wildlife refuge in the northwestern part of the state.129 The remainder of the state would be divided into zones of regulated hunting and unregulated take. Specifically, the rule would end the wolf's protection as either a DPS or an Ex Pop. The rule is contingent upon the Wyoming legislature's passing a wolf management plan that meets certain criteria specified in the proposed rule; the rule would not be finalized until the legislature's approval of the plan.130 The rule makes certain assumptions about the management of wolves on federal lands. Comments to the proposed rule are accepted until January 13, 2012.
According to FWS, the Wyoming management plan, if enacted by the state legislature, would permanently place wolves in one of three management zones: (1) protected zone, with hunting forbidden; (2) hunted zone, with wolf hunting subject to quotas; and (3) unregulated hunting zones. The first two categories, taken together, would constitute 15.7% of the area of the state and would include two national parks and a wildlife refuge.131 In the remainder of the state, wolves would be treated as predator species, and would "experience unregulated human-caused mortality, although mortality in this area will be monitored through mandatory reporting within 10 days of the kill."132 The state would manage wolf populations at 10 breeding pairs or 100 wolves in areas under state jurisdiction.133 Passage by the state of the FWS-approved management plan would provide the chief enforcement mechanism for wolf management in these areas once wolf protection under ESA would end, and the FWS states that the proposed rule would not be finalized until after the legislature meets and passes such a plan. Assuming it does, any future change in the plan by the legislature (e.g., changing zones or management quotas) would appear to leave FWS with the primary remedy of re-listing the species, if the change seemed inadequate to conserve the species.
The FWS proposal is somewhat unclear on which areas are in which of the three wolf management zones. Perhaps most confusing is the determination of which lands fall in zone 1 (protected, no hunting) versus which would be in zone 2 (trophy hunting allowed).
Hunting is allowed in national parks per se only if authorized by the statute that created the park.134 Consequently, the protection for wolves in Yellowstone National Park and Grand Teton National Park is unchanged: they cannot be hunted in those units. On the other hand, while hunting of wolves is not now permitted in the John D. Rockefeller Memorial Parkway (one of the 394 units in the National Park System), which lies between the two parks, the enabling legislation for the Parkway provides the following:
The Secretary shall permit hunting and fishing within the area described by section 1(a) of this Act in accordance with applicable laws of the United States and the State of Wyoming, except that the Secretary may designate zones where, and periods when, no hunting or fishing shall be permitted for reasons of public safety, administration, or public use and enjoyment.135
If wolves are no longer protected under ESA, then hunting in the Parkway would be prohibited (i.e., zone 1) either if the Secretary (acting through NPS) forbids it, or if the Wyoming management plan were to forbid it. Otherwise, wolves in the Parkway might be considered as trophy game (zone 2); if so, their populations might be reduced, as long as the state maintained the 100 wolves/10 breeding pairs quota for the state, as described above. Given the central location of the Parkway, trophy hunting in the Parkway could affect wolf populations in both parks. It is not clear from the text and an accompanying map whether the Parkway is intended as zone 1 or 2.
Restrictions on wolf hunting in refuges could also be clarified. Hunting is commonly allowed in many units of the National Wildlife Refuge System. Specifically, in the National Elk Refuge (NER, the only National Wildlife Refuge in northwestern Wyoming), hunting is allowed for elk and bison.136 The FWS notice indicates that its regulations would provide that no wolf hunting will be allowed in the NER. Is the current and proposed prohibition on wolf hunting permanent, either through the permanency of the state's management plan or through FWS regulations, and if not, what role would the state play in the NER in future wolf management?
Additionally, the FWS notice indicates that in 15.7% of the state's area, wolves would be categorized as "permanently managed as game animals or protected."137 This category, in addition to the above-referenced three park units and wildlife refuge, would include "adjacent U.S. Forest Service-designated Wilderness Areas, adjacent public and private lands ... and the Wind River Indian Reservation." Currently, the tribe forbids all hunting on the reservation, except by members of the Shoshone and Arapahoe tribes.138 Any hunting on the reservation is not regulated by the state.139 According to FWS, "the Wind River Indian Reservation may consider legal regulated harvest" at some future time.140 Any management plans or agreements on such plans with the tribes are not specified in the proposal.
While the proposal would specify designated wilderness as part of the zone in which wolves could be hunted as trophy animals, the Wilderness Act itself does not prevent hunting in designated wilderness.141 States have traditionally worked closely with the federal agencies that manage lands where hunting occurs to set harvest quotas, and Forest Service regulations also provide that wilderness designations do not change the state's right to control fish and game.142 It appears that the Wyoming plan is to be a formal proposal to prohibit wolf hunting in those Forest Service wilderness areas under state law.
The authority of private landowners to take wolves on their land has been an important issue in Wyoming, particularly among the ranching community, but among others as well. South and east of the two parks, significant amounts of private lands are included in Zone 2. Private landowners may object to their land's use (i.e., ability to take wolves) being limited by the state's plan.
Finally, the map included in the proposed rule appears to contradict some of the narrative of the proposed rule.143 The map includes all of Grand Teton National Park, John D. Rockefeller Jr. Memorial Parkway, and NER within the boundaries of the trophy hunting area, although the text states that hunting is to be prohibited in Grand Teton and NER, and is unclear whether it would be prohibited in the Parkway. According to this map, the Wind River reservation falls outside of the protected trophy hunting area, although the text (cited above) includes it in the trophy area.
Section 4(d) Rules for Gray Wolves
According to FWS, Section 4(d) rules are intended to reduce conflicts between the provisions of the Act and needs of people near the areas occupied by the species. Special rules have been in effect for the threatened gray wolves in Minnesota for many years, and were extended to gray wolves in other states, when and where the wolf was downlisted. Under the rule for Minnesota, individual "wolves that have preyed on domestic animals can be ... killed by designated government agents."144 FWS asserts that this rule avoids "even larger numbers of wolves being killed by private citizens who might otherwise take wolf control into their own hands."145
In 2003 as part of the rulemaking that was vacated, FWS issued special rules for two DPSs: Eastern and Western. The special rules would have allowed individuals to kill Western DPS wolves in the act of attacking livestock on private land, and to harass wolves near livestock. Permits to kill wolves could also be issued to landowners who showed wolves routinely were present and formed a significant risk to livestock. FWS said that, as in Minnesota, the rule would "increase human tolerance of wolves in order to enhance the survival and recovery of the wolf population."146 Michigan and Wisconsin citizens would be able to kill any wolf within one mile of killed livestock, and in other Eastern states beside Minnesota, any lethal measures could be used within four miles of such a site.147 This rule was vacated, as discussed in "2003 Western, Eastern, and Southwestern DPS Litigation." When FWS settled the case challenging the 2009 delisting of the Western Great Lakes DPS, the special rule was put back into effect.148
Section 4(d) Rules for Yellowstone and Idaho Experimental Populations
In 2005 after FWS found that the wolf population had exceeded its minimum recovery goals of 30 breeding pairs for Yellowstone and Central Idaho, it issued a rule to manage wolves where they had an unacceptable impact on ungulate populations.149 This 2005 Rule modified the provisions put in effect when the wolves were first introduced, which stated that "wolves could not be deliberately killed solely to resolve predation conflicts with big game."150 When the 2009 Northern Rocky Mountains DPS rule was reissued, the special rule for the Wyoming Ex Pop was returned to effect.151
The 2005 Rule allowed states and tribes in the area to kill wolves where it was shown they were adversely affecting the populations of deer, antelope, elk, big horn sheep, mountain goats, bison, or moose in the area. Before the states and tribes could act, they were required to submit the plan for peer review, public comment, and FWS approval. Data at the time, from many sources cited by FWS, showed that wolf predation was "unlikely to be the primary cause of a reduction of any ungulate herd or population in Idaho, Wyoming, or Montana."152 FWS reported that more wolves were killed (by wildlife agents or by hunting) in each year from 2007 through 2010, than cattle were killed by wolves.153 The wolf population in the area was estimated at 1,651 for 2010.154
In 2008 FWS changed the special rule.155 FWS determined that the definition of unacceptable impact had to be altered, as wolves were not the primary cause in ungulate population decreases. Accordingly, the definition was modified to mean: "Impact to a wild ungulate population or herd where a State or Tribe has determined that wolves are one of the major causes of the population or herd not meeting established State or Tribal population or herd management goals."156 Public and peer reviews are still required. The plan allows a state to kill wolves, provided the experimental population does not go below 20 breeding pairs in the state.157 Additionally, wolves found by wildlife officials to be hybrids may be killed.158
The 2008 Rule also expands the provision for killing wolves when they are in the act of attacking livestock or dogs. The 2005 Rule allowed an individual to "take" a wolf that was in the act of attacking stock animals or dogs on private property. The 2008 Rule allows individuals to take wolves that are in the act of attacking livestock or dogs on public lands as well, except for National Park Service property.159 When the 2009 delisting of the Northern Rockies DPS was invalidated by a court, FWS reinstated the special rules regarding the Ex Pops in the area.160
In February 2011 FWS proposed to allow Idaho to kill some wolves across five years to help the elk population rebound.161 The rule would modify the special rules for Ex Pops.
All the definitions are from Henry W. Art (ed.), The Dictionary of Ecology and Environmental Science (New York: Henry Holt and Co. 1993).

For example, should global warming proceed and arctic snow cover diminish, will the genes for white coats diminish in the arctic wolves? That may be likely, since more brightly colored wolves would be at a disadvantage in much of the year and over a growing area. Natural selection would then tend to disfavor these animals and their offspring.

This language appears to mean that Minnesota, Wisconsin, and Michigan wolves shall not be treated as protected under or covered by the ESA, but those italicized words are not in the bill. It is not clear how H.R. 838 would affect existing federal protection because of this wording.
The bill defines gray wolf to include Canus [sic] lycaon, and Canus [sic] lupus baileyi (the Mexican wolf).
Lone wolves are often secretive and hide to avoid attack by resident packs.

Also see CRS Report R41816, National Park System: What Do the Different Park Titles Signify?, by [author name scrubbed], for a description of uses. The report states that "although Congress may authorize specific land uses in any type of park unit, in practice, activities that might damage or consume resources (sometimes called "consumptive" activities) are more often permitted in some types of units than in others. In particular, Congress has been reluctant to allow consumptive uses in national parks. For example, Congress has not authorized sport hunting in any national parks, whereas this activity is authorized in some other types of units, including some national recreation areas, national preserves, national rivers, national monuments, and national seashores and lakeshores."
