    OPINION
    The Colorado River Cutthroat Trout, the only trout indigenous to the upper
    Colorado River basin, once occupied a range of approximately 21,386 stream miles throughout
    western North America. During the nineteenth and early twentieth centuries, the trout’s
    population levels plummeted, and its current habitat measures only 3022 miles. Although its
    population levels appear to have stabilized in recent decades, the trout continues to face various
    threats.
    On June 13, 2007, the U.S. Fish and Wildlife Service announced its finding that
    listing the trout as endangered or threatened under the Endangered Species Act was not
    warranted at this time. Not Warranted Finding, 72 Fed. Reg. at 32,589.1 Plaintiffs Colorado
    River Cutthroat Trout, Center for Biological Diversity, and Noah Greenwald have challenged the
    1
    12-Month Finding for a Petition to List the Colorado River Cutthroat Trout as
    Threatened or Endangered (the “Not Warranted Finding” or the “Finding”), 
    72 Fed. Reg. 32,589
    (June 13, 2007), Administrative Record (A.R.) at 1.
    FWS’s finding, as well as a related legal memorandum by the Department of the Interior, as
    arbitrary and capricious and in violation of the Endangered Species Act. Plaintiffs and
    defendants both moved for summary judgment, and defendants moved to dismiss plaintiffs’
    claim pertaining to the related legal memorandum.
    Upon careful consideration of the parties’ papers, applicable law, and the entire
    record in the case, the Court finds that the Not Warranted Finding was not contrary to the statute
    or arbitrary and capricious.2 The Court also finds that plaintiffs’ challenge to the related legal
    memorandum has been mooted by the formal withdrawal of the memorandum by the agency.
    Therefore, by Order of September 28, 2012, the Court granted the defendants’ motion for
    summary judgment as to the first claim, granted the defendants’ motion to dismiss as to the
    second claim, and denied the plaintiffs’ motion for summary judgment. This Opinion explains
    the reasoning underlying that Order.

    I. BACKGROUND
    A. Statutory and Regulatory Framework
    The Endangered Species Act (“ESA”), 
    16 U.S.C. § 1531
     et seq., is generally
    considered to be “the most comprehensive legislation for the preservation of endangered species
    ever enacted by any nation.” In re Am. Rivers & Idaho Rivers United, 
    372 F.3d 413
    , 414 (D.C.
    Cir. 2004) (citing Tennessee Valley Auth. v. Hill, 
    437 U.S. 153
    , 180 (1978)). The ESA
    “provide[s] a means whereby the ecosystems upon which endangered species and threatened
    species depend may be conserved [and] . . . a program for the conservation of such endangered
    species and threatened species[.]” 
    16 U.S.C. § 1531
    (b). The Department of the Interior, which is
    ultimately responsible for implementation of the ESA with respect to land-based and freshwater
    species, has delegated primary enforcement authority to the Fish and Wildlife Service (“FWS”),
    an agency within the Department of the Interior. See Spirit of Sage Council v. Norton, 
    294 F. Supp. 2d 67
    , 75 (D.D.C. 2003).
    An “endangered species” is “any species which is in danger of extinction
    throughout all or a significant portion of its range[.]” 
    16 U.S.C. § 1532
    (6). A “threatened
    species” is “any species that is likely to become an endangered species within the foreseeable
    future throughout all or a significant portion of its range[.]” 
    16 U.S.C. § 1532
    (20). The ESA
    provides for any “interested person” to petition the Secretary of the Interior to list a species as
    threatened or endangered, and the Secretary has 90 days to determine whether the petition
    “presents substantial scientific or commercial information indicating that the petitioned action
    may be warranted.” 
    16 U.S.C. § 1533
    (b)(3)(A); see also 
    50 C.F.R. § 424.14
    . Within twelve
    months of receiving a petition that presents such substantial information, and after undertaking a
    3
    review of the species’ status, the Secretary must publish findings in the Federal Register that
    indicate whether the petitioned action is not warranted, warranted, or warranted but precluded.
    
    16 U.S.C. § 1533
    (b)(3)(B)(i)-(iii).
    The ESA directs the Secretary of the Interior to base the finding of whether a
    species is “endangered” or “threatened” on:
    any of the following factors: (A) the present or threatened destruction,
    modification, or curtailment of its habitat or range; (B) overutilization for
    commercial, recreational, scientific, or educational purposes; (C) disease or
    predation; (D) the inadequacy of existing regulatory mechanisms; or (E) other
    natural or manmade factors affecting its continued existence.
    
    16 U.S.C. § 1533
    (a)(1). FWS regulations further provide that this decision must be based on
    “any one or a combination” of these factors and “solely on the best scientific and commercial
    data available” after conducting a status review of the species. 
    50 C.F.R. § 424.11
    (c). It is also
    agency policy to solicit “independent peer review . . . on listing recommendations . . . to ensure
    the best biological and commercial information is being used in the decision making process[.]”
    Notice of Interagency Cooperative Policy for Peer Review in Endangered Species Act Activities,
    
    59 Fed. Reg. 34,270
    , 34,270 (July 1, 1994).
    B. Colorado River Cutthroat Trout
    The Colorado River cutthroat trout, Oncorhynchus clarkii pleuriticus (the
    “Trout”), is the only salmonid native to the upper Colorado River basin, and is one of fourteen
    subspecies of cutthroat trout known to be native to interior regions of western North America.
    Not Warranted Finding, 72 Fed. Reg. at 32,590. The Trout exhibits orange or red slash parts on
    both sides of the lower jaws, and sexually mature males are brightly colored. Id. At the
    4
    beginning of the nineteenth century, the Trout occupied a range of approximately 21,386 stream
    miles, running through Wyoming, Colorado, Utah, New Mexico, and possibly Arizona. Id.
    Currently, the Trout occupies 3022 miles, or 14%, of its historic range, and is found in Colorado,
    Utah, and Wyoming. Id. at 32,600.
    The parties agree that a variety of threats, natural and manmade, can affect the
    Trout and its habitat. See Pls.’ Mot. Summ. at 5-6 (citing grazing, dams and water diversions,
    logging, oil and gas development, hybridization, disease, small and isolated populations, and
    natural disasters); Defs.’ Mot. Summ. at 12-13 (citing habitat fragmentation, population isolation
    and loss of genetic diversity, hybridization, disease, random catastrophes, and land use activities
    such as grazing and road-building). Much of the initial decline in Trout distribution from its
    historic range resulted from the stocking of nonnative sport fish, which “caused problems
    through hybridization, competition, and predation.” Not Warranted Finding, 72 Fed. Reg. at
    32,599. This stocking occurred primarily in the late nineteenth and early twentieth centuries, is
    no longer practiced by fish and wildlife agencies, and no longer occurs near most Trout
    populations. Id. at 32,599; see also Pls.’ Mot. Summ. at 5. In addition, states are implementing
    programs to remove nonnative competitor species from Trout waters. Id. at 32,597.
    C. Procedural History
    This action stems from a December 9, 1999, petition that plaintiffs filed with the
    FWS to list the Trout as an endangered or threatened species. See Colorado River Cutthroat
    Trout v. Kempthorne, 
    448 F. Supp. 2d 170
    , 174 (D.D.C. 2006). In October 2000, plaintiffs filed
    suit in this Court, contending that the FWS violated the ESA by failing to issue the required
    5
    90-day finding on the petition. 
    Id.
     In April 2004, the FWS issued the 90-day finding, which
    concluded that the petition did not “present substantial information that listing the trout may be
    warranted.” Id.; 90-Day Finding on a Petition to List the Colorado River Cutthroat Trout, 
    69 Fed. Reg. 21,151
     (Apr. 20, 2004). Plaintiffs then amended their complaint to challenge the
    sufficiency of the 90-day finding. Colorado River Cutthroat Trout v. Kempthorne, 
    448 F. Supp. 2d at 174
    . The Court awarded summary judgment to the plaintiffs after finding that the FWS had
    “solicited information and opinions from limited outside sources” rather than considering the
    petition alone in making its decision, which rendered the FWS’s consideration of the petition
    “procedurally flawed.” 
    Id. at 177
    . Consequently, the Court ordered the FWS to conduct a “full
    status review of the [Trout] within nine months . . . and issue a 12-month finding on the [Trout]”
    after the status review and public comment period. 
    Id. at 179
    .
    On November 7, 2006, the FWS announced the commencement of its status
    review, which involved a public comment period through January 8, 2007, as well as two
    scheduled public workshops. 12-Month Finding on a Petition to List the Colorado River
    Cutthroat Trout as Threatened or Endangered, 
    71 Fed. Reg. 65,064
    , 65,065 (Nov. 7, 2006).
    While the status review was underway, the then-Solicitor of the Department of the Interior issued
    a memorandum defining “a significant portion of its range” as that term is used in the ESA. See
    M-37013, Solicitor’s Memorandum Regarding Meaning of “In Danger of Extinction Throughout
    All or a Significant Portion of its Range” (March 16, 2007) (the “Solicitor’s Memorandum”),
    [Dkt. No. 16-2]. On June 13, 2007, the FWS issued its 12-month finding, which announced that
    the Trout “is not now in danger of extinction (endangered), nor is it likely to become endangered
    within the foreseeable future (threatened).” Not Warranted Finding, 72 Fed. Reg. at 32,600.
    6
    Accordingly, the FWS found that listing the Trout as a threatened or an endangered species under
    the ESA was not warranted at this time. Id. Although the FWS did not mention the Solicitor’s
    Memorandum in its Finding, the FWS adopted an interpretation of “significant portion of its
    range” that was consistent with that set forth in the Solicitor’s Memorandum. On November 24,
    2009, plaintiffs filed the instant case, challenging the FWS’s Not Warranted Finding and the
    Solicitor’s Memorandum under the ESA and the Administrative Procedure Act (“APA”).
    II. LEGAL STANDARDS
    A. Endangered Species Act and Administrative Procedure Act
    The ESA provides for judicial review of an agency’s “not warranted” finding. 
    16 U.S.C. § 1533
    (b)(3)(C)(ii). The APA provides the standard for judicial review of agency listing
    decisions. See Am. Wildlands v. Kempthorne, 
    530 F.3d 991
    , 997 (D.C. Cir. 2008). The
    reviewing court may set aside agency actions, findings, or conclusions when they are arbitrary,
    capricious, an abuse of discretion, or otherwise not in accordance with the law. 
    5 U.S.C. § 706
    (2)(A).
    The standard of review of agency action is “a highly deferential one.” Am.
    Wildlands v. Kempthorne, 
    530 F.3d at 997
     (quoting Ethyl Corp. v. EPA, 
    541 F.2d 1
    , 34 (D.C.
    Cir. 1976)). There is a strong, albeit rebuttable presumption in favor of upholding decisions of
    the FWS in view of its expertise in the area of wildlife conservation and management and the
    deferential standard of review. Colorado River Cutthroat Trout v. Kempthorne, 
    448 F. Supp. 2d at 174
    ; see Marsh v. Oregon Natural Res. Council, 
    490 U.S. 360
    , 375-78 (1989). If the agency
    has “considered the relevant factors and articulated a rational connection between the facts found
    7
    and the choice made,” its decision cannot be considered arbitrary and capricious. Colorado River
    Cutthroat Trout v. Kempthorne, 
    448 F. Supp. 2d at 174
     (quoting Baltimore Gas & Elec. Co. v.
    Natural Res. Def. Council, 
    462 U.S. 87
    , 105 (1983)). The Court’s review, however, must be
    “searching and careful.” Nat’l Envtl. Dev. Assn’s Clean Air Project v. E.P.A., 
    686 F.3d 803
    , 810
    (D.C. Cir. 2012) (quoting Ethyl Corp. v. EPA, 
    541 F.2d at 36-37
    ).
    As explained in more detail below, one of plaintiffs’ principal arguments
    challenges the FWS’s interpretation of the ESA. The court must defer to the agency’s
    interpretation of a statute that it implements “so long as it is reasonable, consistent with the
    statutory purpose, and not in conflict with the statute’s plain language.” OSG Bulk Ships v.
    United States, 
    132 F.3d 808
    , 814 (D.C. Cir. 1998) (quoting Coal Emp’t Project v. Dole, 
    889 F.2d 1127
    , 1131 (D.C. Cir. 1989)). When the action under review involves an agency’s interpretation
    of a statute that the agency is charged with administering, the court applies the familiar analytical
    framework set forth in Chevron U.S.A., Inc. v. Natural Res. Def. Council, Inc., 
    467 U.S. 837
    (1984). Under step one of Chevron, the court asks “whether Congress has directly spoken to the
    precise question at issue, in which case we must give effect to the unambiguously expressed
    intent of Congress.” Sec’y of Labor, Mine Safety and Health Admin. v. Nat’l Cement Co. of
    California, Inc., 
    494 F.3d 1066
    , 1073 (D.C. Cir. 2007) (internal quotation marks and citation
    omitted); see also Chevron U.S.A., Inc. v. Natural Res. Def. Council, Inc., 
    467 U.S. at 842-43
    .
    If the court concludes that “the statute is silent or ambiguous with respect to the
    specific issue,” the court moves “to the second [Chevron] step and defer[s] to the agency’s
    interpretation as long as it is ‘based on a permissible construction of the statute.’” Sec’y of
    Labor, Mine Safety and Health Admin. v. Nat’l Cement Co. of California, Inc., 
    494 F.3d at
    1074
    8
    (quoting Chevron U.S.A., Inc. v. Natural Res. Def. Council, Inc., 
    467 U.S. at 843
    ). “A
    ‘reasonable’ explanation of how an agency’s interpretation serves the statute’s objectives is the
    stuff of which a ‘permissible’ construction is made.” Northpoint Tech., Ltd. v. F.C.C., 
    412 F.3d 145
    , 151 (D.C. Cir. 2005) (citing Cont’l Airlines v. Dep’t of Transp., 
    843 F.2d 1444
    , 1452 (D.C.
    Cir. 1998)). Therefore, the court must focus on “whether the [agency] has reasonably explained
    how the permissible interpretation it chose is ‘rationally related to the goals of’ the statute.” Petit
    v. U.S. Dept. of Educ., 
    675 F.3d 769
    , 785 (D.C. Cir. 2012) (alteration in original) (quoting
    Village of Barrington, Ill. v. Surface Transp. Bd., 
    636 F.3d 650
    , 665 (D.C. Cir. 2011)). “Unlike
    our Chevron step one analysis, our review at this stage is ‘highly deferential.’” Village of
    Barrington, Ill. v. Surface Transp. Bd., 
    636 F.3d at
    665 (citing Nat'l Rifle Assn of Amer. v. Reno,
    
    216 F.3d 122
    , 137 (D.C. Cir. 2000)).
    B. Summary Judgment
    Summary judgment may be granted “if the movant shows that there is no genuine
    dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R.
    Civ. P. 56(a). In a case involving review of a final agency action under the APA, however, the
    Court’s role is limited to reviewing the administrative record; the standard set forth in Rule 56
    does not apply. See Catholic Health Initiatives v. Sebelius, 
    658 F. Supp. 2d 113
    , 117 (D.D.C.
    2009), rev’d on other grounds, 
    617 F.3d 490
     (D.C. Cir. 2010); Cottage Health Sys. v. Sebelius,
    
    631 F. Supp. 2d 80
    , 89-90 (D.D.C. 2009). “Under the APA, it is the role of the agency to resolve
    factual issues to arrive at a decision that is supported by the administrative record, whereas ‘the
    function of the district court is to determine whether or not as a matter of law the evidence in the
    9
    administrative record permitted the agency to make the decision it did.’” Catholic Health
    Initiatives v. Sebelius, 
    658 F. Supp. 2d at 117
     (quoting Cottage Health Sys. v. Sebelius, 
    631 F. Supp. 2d at 90
    ). Summary judgment thus serves as “the mechanism for deciding, as a matter of
    law, whether the agency action is supported by the administrative record and otherwise consistent
    with the APA standard of review.” Cottage Health Sys. v. Sebelius, 
    631 F. Supp. 2d at
    90 (citing
    Richards v. INS, 
    554 F.2d 1173
    , 1177 & n. 28 (D.C. Cir. 1977)).
    III. ANALYSIS
    A. Claim 1: “Not Warranted Finding”
    Plaintiffs claim that the FWS’s Not Warranted Finding violates the ESA and is
    arbitrary and capricious, and therefore must be vacated. Plaintiffs contend that the FWS acted
    unlawfully by allegedly (1) failing to consider whether the Trout’s lost historic range and certain
    portions of the current range constitute “significant portion[s] of its range” as used in the ESA;
    (2) considering the ESA’s listing factors in isolation, rather than in combination, to determine the
    severity of threats faced by the Trout; (3) failing to consider the impact of climate change in
    assessing threats to the Trout; (4) improperly considering voluntary conservation plans when
    reviewing existing regulatory protections for the Trout; (5) deviating from the ESA’s requirement
    to employ the “best scientific and commercial data available”; and (6) erroneously analyzing the
    evidence in the record. The Court addresses each of plaintiffs’ challenges in turn.
    10
    1. The FWS’s Interpretation of “Significant Portion of Its Range”
    The ESA defines an endangered species as one “in danger of extinction
    throughout all or a significant portion of its range[.]” 
    16 U.S.C. § 1532
    (6) (emphasis added).3
    In its Not Warranted Finding, the FWS explicitly interpreted the term “range” as signifying the
    current range of the Trout, which measures 3022 miles. The FWS explained:
    The Act does not indicate threshold levels of historic population
    size at which, as the population of a species declines, listing as
    either “threatened” or “endangered” becomes warranted. Instead,
    the principal considerations in the determination of whether or not
    a species warrants listing as a threatened or an endangered species
    under the Act are the threats that now confront the species and the
    probability that the species will persist in “the foreseeable future.”
    . . . We evaluated the [Colorado River cutthroat trout] throughout
    its current range to determine if any portion is likely to become
    threatened or endangered within the foreseeable future, and if so,
    whether that portion is significant relative to the remainder of the
    species' range.
    Not Warranted Finding, 72 Fed. Reg. at 32,599-600 (emphasis added). The FWS proceeded to
    explain its interpretation of significance: “For an area to be significant, it must meaningfully
    contribute to the resilience, redundancy, or representation of a species.” Id. at 32,600.
    Plaintiffs allege that the FWS violated the ESA by (1) failing to consider whether
    the lost portion of the Trout’s historic range constitutes “a significant portion of its range”, and
    (2) failing to explain why the portions of the current range occupied only by Trout that have
    interbred with other subspecies are deemed to be insignificant.
    3
    The statute likewise defines “threatened species” as one “likely to become an
    endangered species within the foreseeable future throughout all or a significant portion of its
    range[.]” 
    16 U.S.C. § 1532
    (20).
    11
    a. Failure to Consider the Trout’s Lost Historic Range
    The ESA does not define what constitutes a species’ “range” nor what is
    considered “significant”, leading courts to view the phrase “in danger of extinction throughout all
    or a significant portion of its range” as “inherently ambiguous”. See Defenders of Wildlife v.
    Norton, 
    258 F.3d 1136
    , 1141 (9th Cir. 2001); see also WildEarth Guardians v. Salazar, 
    741 F. Supp. 2d 89
    , 99 (D.D.C. 2010). As the Ninth Circuit observed:
    Standing alone, the phrase “in danger of extinction throughout . . .
    a significant portion of its range” is puzzling. According to the
    Oxford English Dictionary, “extinct” means “has died out or come
    to an end . . . Of a family, class of persons, a race of species of
    animals or plants: Having no living representative.” Thus, the
    phrase “extinc[t] throughout . . . a significant portion of its range”
    is something of an oxymoron.
    Defenders of Wildlife v. Norton, 
    258 F.3d at 1141
     (internal footnote omitted).
    The question of whether a sizeable decline in historic range is “a significant
    portion of its range” under the ESA has received considerable attention in the last decade, as the
    FWS has persistently restricted the scope of ‘range’ to a species’ current range and
    environmental groups have urged a broader reading. See, e.g., Tucson Herpetological Soc’y v.
    Salazar, 
    566 F.3d 870
    , 876 (9th Cir. 2009); Defenders of Wildlife v. Sec’y, U.S. Dep’t of the
    Interior, 
    354 F. Supp. 2d 1156
    , 1164-67 (D. Or. 2005); see also Defs.’ Mot. Summ. at 15 (“The
    [FWS’s] long standing view . . . is that “range” refers to areas currently occupied or used, and the
    determination of extinction risk is fundamentally forward looking”). In 2007, the Solicitor of the
    Department of the Interior issued a memorandum to the Director of the FWS, in which the
    Solicitor advised that “range” should be interpreted as referring only to a species’ current range.
    See Solicitor’s Memorandum at 7-8 (“The phrase ‘is in danger’ denotes a present-tense condition
    12
    of being at risk of a future, undesired event. Hence, to say a species “is in danger” in an area
    where it no longer exists . . . would be inconsistent with common usage”). Defendants also argue
    that the size of a species’ range generally grows and contracts over time; as a result, pinpointing
    one fixed historic range would be an inherently arbitrary exercise. See Defs.’ Reply at 8 (noting
    that one study identified the Trout’s historic range as the habitat occupied 11,000 years ago,
    while another looked to the habitat occupied two centuries ago).
    Several environmental groups, such as plaintiffs, have expressed concern that a
    focus on the current range will lead to reduced protections for at-risk species, contrary to the
    ESA’s purpose. See Pls’ Mot. Summ. at 47-48. Plaintiffs raise the possibility, for example, that
    the interpretation of range as current range could “‘create incentives that could work against
    fundamental goals of the ESA’ because ‘regulators might be inclined to delay listing decisions in
    the hope that critically endangered populations would disappear, allowing the current range of
    the species to be recalibrated downwards.’” Pls.’ Mot. Summ. at 47-48 (citing Robin S. Waples
    et al., Legal Viability, Societal Values, and SPOIR: Response to D’Elia et al., 22 Conservation
    Biology 1075, 1077 (2008), (Dkt. No. 38, Exh. 22)). Plaintiffs also assert that the ESA expressly
    instructs the agency to consider range or habitat that has recently been lost. Pls.’ Mot. Summ. at
    16; see 
    16 U.S.C. § 1533
    (a)(1) (requiring consideration of the “present or threatened destruction,
    modification, or curtailment of [the species’] habitat or range”).
    The Court acknowledges this tension but finds that the Ninth Circuit’s approach
    provides an instructive way to address it. In Defenders of Wildlife v. Norton, 
    258 F.3d 1136
     (9th
    Cir. 2001), the Ninth Circuit examined the Secretary of the Interior’s decision not to designate
    the flat-tailed horned lizard as threatened under the ESA, despite a loss of 34 percent of the
    13
    lizard’s historic range over the twentieth century. 
    Id. at 1141
    . The court did not rule on whether
    “range” should be equivalent to historic range or current range, nor did it lay out a definition for
    the term “significant”. It did find, however, that the FWS was required to explain its reasons for
    finding that the lost range was not significant:
    [A] species can be extinct ‘throughout . . . a significant portion of
    its range’ if there are major geographical areas in which it is no
    longer viable but once was . . . The Secretary necessarily has a
    wide degree of discretion in delineating ‘a significant portion of its
    range,’ since the term is not defined in the statute. But where, as
    here, it is on the record apparent that the area in which the lizard is
    expected to survive is much smaller than its historical range, the
    Secretary must at least explain her conclusion that the area in
    which the species can no longer live is not a ‘significant portion of
    its range.
    
    Id.
     at 1145 (citing Asarco, Inc. v. EPA, 
    616 F.2d 1153
    , 1159 (9th Cir. 1980)) (emphasis added).
    The Ninth Circuit revisited the case of the flat-tailed horned lizard in Tucson
    Herpetological Soc’y v. Salazar, 
    566 F.3d 870
    , 876 (9th Cir. 2009). In reviewing the FWS’s
    decision not to list the lizard as threatened, the Ninth Circuit found that the Secretary had
    “analyze[d] the lizard’s lost habitat in a site-specific manner” and had reasonably concluded that
    the lost portions of the range “[did] not provide any unique or critical function for the well-being
    of the species[.]” 
    Id. at 877
    . The Ninth Circuit also found persuasive the Secretary’s observation
    that much of the lost range had been converted to other uses decades before and generally was
    not recoverable, and was “thus of limited significance to the lizard’s long-term survival.” Id. at
    868. Because the FWS had explained its conclusion that the lost range was not a “significant
    portion of its range”, and in light of the deferential standard of review, the court upheld the
    agency’s decision.
    14
    Other judges in this District have adopted the Ninth Circuit’s approach of
    requiring that the FWS provide some reasoning for why a historical contraction in range does not
    reflect a “risk of extinction throughout . . . a significant portion of its range[.]” 
    16 U.S.C. § 1532
    (6). See Defenders of Wildlife v. Norton, 
    239 F. Supp. 2d 9
    , 20 (D.D.C. 2002) (Kessler,
    J.), vacated in part on other grounds, 
    89 Fed. Appx. 273
     (D.C. Cir. 2004) (vacating and
    remanding finding in part because FWS failed to explain its conclusion that three out of four
    discrete geographic areas historically inhabited by Canada Lynx were not “significant”);
    WildEarth Guardians v. Salazar, 
    741 F. Supp. 2d at 98-101
     (Kollar-Kotelly, J.) (vacating and
    remanding finding where FWS failed to explain why a 50 to 87 percent reduction in Utah prairie
    dog’s range was not significant).
    In this case, the FWS explicitly defined the term “range” as signifying the Trout’s
    current range of approximately 3022 miles. See Not Warranted Finding, 72 Fed. Reg. at 32,599-
    600. Despite plaintiffs’ contentions, however, the FWS also provided an adequate analysis of the
    Trout’s historic range and discussed why the historic contraction of its range does not render the
    Trout vulnerable in any significant portion of its currently occupied habitat. 72 Fed. Reg. at
    32,590. Although the Trout’s current distribution is “approximately 14 percent of probable
    historically occupied stream miles” the FWS explained that the Trout are well-distributed
    throughout this area. Id. The FWS further explained that the loss in population over the last 200
    years occurred primarily in the late nineteenth and early twentieth centuries, as a result of
    nonnative sport fish stocking. Id. at 32,597-99. The FWS did not find evidence of recent
    declines in the overall distribution or abundance of the Trout, but rather found evidence that the
    number of known populations is increasing. Id. at 32,599. Plaintiffs argue that the FWS may not
    15
    simply “point to one area or class of areas where [Trout] populations persist to support a finding
    that threats to the species elsewhere are not significant; the ESA requires a more thorough
    explanation.” Pls’ Mot. Summ. at 17 (quoting Tucson Herpetological Soc’y v. Salazar, 
    566 F.3d at 876
    ). This Court concludes, however, that the FWS, in analyzing the distribution of the
    Trout’s current range, identifying recent population trends, and detailing the cessation of the
    primary cause of past reduction, has provided that more thorough explanation.
    b. Failure to Consider Unoccupied Portions of the Trout’s Current Range
    Even if “range” is restricted to the Trout’s current range of 3022 miles, plaintiffs
    take issue with the FWS’s conclusion that the Trout are not threatened within a “significant
    portion” of this area. Where a species or subspecies is unlikely to survive in a sizeable portion of
    its current habitat, the agency must provide some explanation as to why this portion is not “a
    significant portion of its range[.]” Defenders of Wildlife v. Norton, 
    239 F. Supp. 2d at
    21 (citing
    Defenders of Wildlife v. Norton, 
    258 F.3d at 1145
    ); see Southwest Center for Biological
    Diversity v. Norton, 98-cv-0934 (D.D.C. May 24, 2004) (instructing FWS to reconsider and
    explain whether an island constituting one-third of species’ range was “significant”). Plaintiffs
    point to the 1226 miles throughout the current range that lack populations of genetically pure (or
    close-to-pure) Trout and argue that the FWS “failed to evaluate the significance of the fact that
    almost half of its remaining range is unoccupied.” Pls.’ Mot. Summ. at 1.
    Although the FWS did not state explicitly that it found these 1226 miles not to be
    a “significant portion” of the range, the FWS clearly articulated how it evaluated significance
    throughout the Finding and in a subsection entitled “significant portion of the range”. The FWS
    explained that it had identified fish populations that met a 90 percent threshold of Trout genetic
    16
    content, such that the populations were unquestionably Trout on a genetic and morphological
    level. Not Warranted Finding, 72 Fed. Reg. at 32,591.4 The 285 Trout populations that met this
    standard were considered “Conservation Populations”. Id.5 The FWS then evaluated the threats
    facing these Conservation Populations in each of the eight major watershed-based regions within
    the range, otherwise known as Geographical Management Units, or “GMUs”. Finding that at
    least some number of Conservation Populations were likely to survive in each GMU, the agency
    concluded that the Trout was not endangered or threatened within “a significant portion of the
    range[.]” Id. at 32,600.
    Each GMU contains large areas – in the aggregate, approximately 1226 miles or
    41 percent of the total range – occupied by cutthroat trout sport fish populations. These sport
    fish populations have the morphological characteristics of the Trout, but they generally contain
    greater than 10 percent genetic material from other subspecies. Not Warranted Finding, 72 Fed.
    Reg. at 32,591. The FWS noted that several state agencies include these sport fish populations in
    their conservation and management plans for the Trout. Id. at 32,598. Because of their relatively
    high level of nonnative genetic material, however, the FWS does not consider the sport fish
    populations to be predictive of the survival of the Trout in its genetically pure form. Id. (“Sport
    fish populations . . . conform morphologically . . . to the scientific taxonomic description of [the
    Trout], but do not meet the additional criteria of “conservation” or “core” populations and hence
    4
    Morphology “refers to the general aspects of biological form and arrangement of
    the parts of a plant or an animal.” Encyclopœdia Britannica Online Academic Edition. (Oct. 12,
    2012), http://www.britannica.com/EBchecked/topic/392797/morphology.
    5
    A subset of Conservation Populations were “Core Conservation Populations”,
    which had greater than 99 percent Trout genes.
    17
    are managed for their value as a sport fish population rather than their value to the conservation
    of the subspecies.”).
    Plaintiffs argue that the FWS failed to explain why these regions containing sport
    fish populations do not constitute “a significant portion of its range[.]” The Court agrees that the
    FWS was often unclear as to whether it considered these sport fish populations to constitute
    Trout at all.6 It is established, however, that a court should “uphold a decision of less than ideal
    clarity if the agency’s path may reasonably be discerned,” as it may be here. Building Industry
    Assn of Superior Cal. v. Babbitt, 
    979 F. Supp. 893
    , 898 (D.D.C. 1997) (citing Motor Vehicles
    Mfrs. Assn v. State Farm Mutual Auto Ins. Co., 
    463 U.S. 29
    , 43 (1983)). This Court finds that
    the FWS’s explicit discussion of how it evaluated significance, accompanied by its explanation
    of those areas of the range occupied by Trout sport fish populations, renders discernible the
    FWS’s reasoning with respect to its evaluation of a significant portion of the Trout’s range.
    Plaintiffs also allege that the FWS failed to explain adequately its use of “GMUs”
    as the analytic tool for determining whether the Trout is threatened in a significant portion of its
    range. Pls.’ Mot. Summ. at 21. The FWS, however, provided a reasonable basis for its selected
    methodology, explaining that the eight GMUs correspond to the major watersheds within the
    range, and that “standardized fish monitoring methods are watershed based.” Not Warranted
    Finding, 72 Fed. Reg. at 32,600; see also id. at 32,593 (noting that under Wyoming agency plan,
    biologists manipulate habitat on a watershed scale). The FWS noted that the eight GMUs
    encompass the entire current and historical range, and Conservation Populations are located in
    6
    Defendants concede that the inclusion of sport fish populations in the current
    range leads to analytic confusion when evaluating Trout sustainability within the range. See
    Defs.’ Reply Mot. at 12.
    18
    every GMU. Id. at 32,600. The FWS also explained that “[n]o significant ecological differences
    exist at levels smaller than the GMUs to affect representation of the subspecies.” Id. The FWS
    concluded that a sufficient number of GMUs existed in order to ensure Trout redundancy and
    resiliency. Id. Although the plaintiffs raise plausible criticisms of the methodology chosen by
    the FWS, an agency’s choice of methodology need only be reasonable to be upheld. See Nat’l
    Envtl. Dev. Assn’s Clean Air Project v. E.P.A., 
    686 F.3d 803
    , 810 (D.C. Cir. 2012) (“[W]e do
    not look at the decisions as would a scientist, but ‘as a reviewing court exercising our narrowly
    defined duty of holding agencies to certain minimal standards of rationality.’”). This Court
    concludes that the FWS’s use of GMUs, and its explanation for their use, pass this test.
    2. Failure to Address Threats in Combination
    Under its regulations, the FWS must consider threats posed by “any one or a
    combination” of the five factors listed in the ESA. 
    16 U.S.C. § 1533
    (a)(1)(A)-(E); see 
    50 C.F.R. § 424.11
    (c); Carlton v. Babbitt, 
    900 F. Supp. 526
    , 530 (D.D.C. 1995). These factors are:
    (A) the present or threatened destruction, modification, or
    curtailment of its habitat or range;
    (B) overutilization for commercial, recreational, scientific, or
    educational purposes;
    (C) disease or predation;
    (D) the inadequacy of existing regulatory mechanisms; or
    (E) other natural or manmade factors affecting its continued
    existence.
    
    16 U.S.C. § 1533
    (a)(1).
    19
    Plaintiffs claim that the FWS violated the ESA’s requirement to consider the
    listing factors in combination. Indeed, in most of its Finding, the FWS considers each of the
    listing factors one by one and determines that the threats do not rise to the level requiring listing.
    See, e.g., Not Warranted Finding, 72 Fed. Reg. at 32,594 (“[W]e conclude . . . that present or
    threatened destruction, modification, or curtailment of habitat or range has not affected the status
    of [Trout] to the extent that listing under the Act as a threatened or endangered species is
    warranted at this time.”); id. at 32,594 (“[I]t does not appear that predation affects the status of
    [the Trout] to the extent that listing under the Act as threatened or endangered is warranted at this
    time.”); id. at 32,596 (“[W]e conclude . . . that any identified inadequacies of existing regulatory
    mechanisms have not affected the status of [the Trout] to the extent that listing under the Act as a
    threatened or endangered species is warranted.”). Plaintiffs assert that the Finding resembles the
    finding vacated and remanded by Judge Kollar-Kotelly in WildEarth Guardians v. Salazar,
    741 F. Supp. 2d at 102
    , because, as in that case, the finding here does not “explicitly indicate that [the
    FWS] analyzed the listing factors’ cumulative effect.” Pls.’ Mot. Summ. at 28-29. Defendants
    maintain, by contrast, that in this case the FWS did in fact consider threats in combination, but
    did so in its discussion of the individual factors, rather than in a separate cumulative effects
    section. Defs.’ Mot. Summ. at 31-32.
    The FWS’s analysis of how the listing factors interact is cited throughout the
    Finding in a somewhat haphazard fashion, but the analysis of how they combine together
    nevertheless is apparent. For example, under the subsection discussing Factor E (other natural or
    manmade factors affecting the Trout’s continued existence), the FWS considered a general
    population health evaluation for each Conservation Population. Not Warranted Finding, 
    72 Fed. 20
    Reg. at 32,596-97. This population health evaluation considered population size, temporal
    variability, population connectivity and production potential, which was based on estimates of
    “habitat quality, presence of nonnative fishes, disease, and land-use impacts[.]” Id.; see also
    Christine L. Hirsch, Shannon E. Albeke, and Thomas P. Nesler, Range-Wide Status of Colorado
    River Cutthroat Trout (March 2006) (“2006 Range-Wide Status Report” or “Report”), A.R. at
    1429 (discussing formulation of population health evaluation). This metric thus considers Factor
    A (present or threatened destruction of habitat or range) in combination with Factor C (disease or
    predation) and Factor E (other factors, such as connectivity issues). In addition, the FWS
    considered the interaction of habitat fragmentation (Factor A) with the exchange of genetic
    information (Factor E). 72 Fed. Reg. at 32,596. The FWS also discussed how the Trout’s
    widespread populations (Factor A) are more vulnerable to threats like fire, flood, and drought
    (Factor E), as well as how this fragmentation protects the Trout from such threats as disease and
    overfishing (Factors B and C). 72 Fed. Reg. at 32,593-94, 32,596.
    The FWS certainly could have been more explicit in articulating the manner in
    which it considered how factors might combine together to intensify or mitigate threats to the
    Trout by outlining its analysis of combined effects in a separate section. Nevertheless, the
    agency’s reasoning can be reasonably discerned here. See Building Industry Assn of Superior
    Cal. v. Babbitt, 
    979 F. Supp. at 898
    . The FWS’s findings – particularly those relating to the
    general population health evaluations – adequately demonstrate a consideration of the listing
    factors in combination, and therefore must be upheld.
    21
    3. Failure to Address Climate Change Effects
    Plaintiffs contend that the FWS should have considered the impact of climate
    change in its assessment. Plaintiffs argue that “climate change will cause significant additional
    reductions in suitable habitat and will especially impact the majority of the Conservation
    Populations because of their small size.” Pls.’ Mot. Summ. at 30.
    Although the ESA does not expressly require consideration of climate change
    effects, it does direct the agency to address “natural or manmade factors affecting [a species’]
    continued existence.” 
    16 U.S.C. § 1533
    (a)(1)(E). As scientific assessments increasingly
    incorporate in-depth analyses of climate change effects, explicit consideration of climate change-
    related threats may become a necessary component of the status review. The record in this case,
    however, contains only occasional references to climate change-related threats. There is no
    statutory requirement that the FWS discuss climate change in its listing decisions, and the Court
    is reluctant to impose a judicially-created requirement where, as here, climate change is not
    discussed at length in the record, where the issue was not raised by plaintiffs in their comments
    to the FWS, and where the record is ambivalent as to its effects. Compare 2006 Range-Wide
    Status Report at 16 (“If global climate change results in shrinkage of [Trout] habitat to higher
    elevations . . . there may be opportunity to establish new self-sustaining populations in lakes and
    streams that were previously too cold for trout recruitment”), with M.K. Young, Colorado River
    Cutthroat Trout: A Technical Conservation Assessment (2006), A.R. at 9397 (describing climate
    change as “greatest future threat to the persistence of this species” because of effects on stream
    movement).
    22
    4. Improper Consideration of Regulatory Management Plans
    Plaintiffs next assert that the FWS improperly relied on the voluntary Colorado
    River Cutthroat Trout Conservation Strategy (“Conservation Strategy”) undertaken by the FWS
    in conjunction with Colorado, Utah, and Wyoming. See Conservation Strategy for Colorado
    River Cutthroat (June 2006), A.R. at 1100; Conservation Agreement and Strategy for Colorado
    River Cutthroat (Apr. 2001), A.R. at 1124. The Conservation Strategy, first initiated in 1997 and
    adopted in 2001, operates to eliminate and reduce “[t]hreats that warrant [Trout] listing as a
    special status species by state and federal agencies and might lead to listing under the
    Endangered Species Act.” Conservation Strategy for Colorado River Cutthroat (June 2006) at 3,
    A.R. at 1102. Much of the increase in Trout populations observed in the Not Warranted Finding
    appears to have occurred after this strategy was put into place. See Not Warranted Finding, 72
    Fed. Reg. at 32,599 (citing 2006 Range-Wide Status Report for “evidence of a substantial
    increase in the number of known populations”); 2006 Range-Wide Status Report at 62 (showing
    dramatic increases in numbers and miles/acres of Conservation Populations between July 1998
    and July 2003).
    In its Not Warranted Finding, the FWS noted that the voluntary agreements under
    the Conservation Strategy “do not qualify as a regulatory mechanism” and that the FWS could
    not base its finding on a “promised or anticipated result of conservation actions[.]” Not
    Warranted Finding, 72 Fed. Reg. at 32,596. Plaintiffs accuse the FWS of relying on the
    Conservation Strategy indirectly, however, and cite a Forest Service report that observes that its
    specific Trout management plans “have largely been superseded by [the Conservation Strategy.]”
    Pls.’ Mot. Summ. at 10-11 (citing M.K. Young, Colorado River Cutthroat Trout: A Technical
    23
    Conservation Assessment 14 (2006), A.R. 9407). But plaintiffs have pointed to no evidence
    showing that the legal classification of the Trout as a “sensitive species” or “species of concern”
    by regulatory agencies has been altered by the Conservation Strategy, which suggests that these
    agencies remain obligated to provide monitoring and protection for the Trout. And while the
    FWS cannot rely on promised and unenforceable conservation agreements in evaluating existing
    regulatory mechanisms, see Biodiversity Legal Found. v. Babbitt, 
    943 F. Supp. 23
    , 26 (D.D.C.
    1996), its consideration of the Conservation Strategy as part of its overall assessment of ongoing
    management practices is not inappropriate. See Not Warranted Finding, 72 Fed. Reg. at 32,597
    (noting, in its discussion of Factor E, that state resource agency programs that prohibit sport fish
    stocking and actively remove sport fish contribute to the maintenance of current Trout habitat).
    5. Failure to Use Best Science Available
    Plaintiffs contend that the FWS violated the ESA’s mandate to make a listing
    decision based on “the best scientific and commercial data available[.]” See 
    16 U.S.C. § 1533
    (b)(1)(A). Plaintiffs take issue with certain methodologies used in the 2006 Range-Wide
    Status Report, which was conducted by a team of biologists from the FWS, U.S. Bureau of Land
    Management, U.S. Forest Service, Wyoming Game and Fish Department, Utah Division of
    Wildlife Resources, and Colorado Division of Wildlife. Plaintiffs first criticize the Report for
    lacking “a threats analysis” specific to the 285 Conservation Populations. Pls.’ Mot. Summ. at
    22. Because this analysis is absent from the Report, plaintiffs assert that the FWS was required
    to undertake its own analysis on this issue.
    The D.C. Circuit distinguishes “best scientific data available” from “best scientific
    data possible.” Building Industry Assn of Superior Cal. v. Norton, 
    247 F.3d 1241
    , 1246 (D.C.
    24
    Cir. 2001). “The [FWS] may not base its listings on speculations or surmise or disregard
    superior data,” but “occasional imperfections do not violate [the ESA].” 
    Id. at 1246-47
    . The
    requirement to use the best available data “makes it clear that the Secretary has no obligation to
    conduct independent studies.” Am. Wildlands v. Kempthorne, 
    530 F.3d at 998
     (quoting
    Southwest Center for Biological Diversity v. Babbitt, 
    215 F.3d 58
    , 60 (D.C. Cir. 2000)).
    Although an individual threats assessment of each Conservation Population would
    certainly have been useful, it is not required under the statute. See 
    16 U.S.C. § 1533
    (a)(1)(A)
    (directing the Secretary to analyze threats to species’ habitat or range, but not mandating a
    particular approach or methodology). The FWS instead relied upon the best data available,
    including the 2006 Range-Wide Status Report, which was peer reviewed in 2006. See Pls.’ Mot.
    Summ. at 10 (citing A.R. at 8692). The Court finds that the FWS met its statutory requirement
    to make a listing decision based on “the best scientific and commercial data available.”
    Plaintiffs next contend that the FWS improperly relied on a “persistence” analysis
    to assess threats to the species’ survival, contrary to its obligation to use the best available
    science.7 Plaintiffs claim that Trout “persistence” does not indicate future survival and therefore
    cannot provide the appropriate metric to determine whether a species is “in danger of extinction.”

    16 U.S.C. § 1532

    “persisted” when that persistence was at a level near extinction). Plaintiffs argue that the FWS
    was obligated to perform a viability assessment similar to that performed for the Rio Grande
    cutthroat trout.
    Plaintiffs’ argument fails on several counts. First, our court of appeals recently
    held that use of data on a species’ “persistence” is not inconsistent with the FWS’ obligation to
    use the “best . . . data available.” See Friends of Blackwater v. Salazar, — F.3d —, 
    2012 WL 3538236
    , at *5 (D.C. Cir. Aug. 17, 2012) (rejecting plaintiffs’ contention that FWS was required
    to use population-based criterion instead of persistence data in delisting decision). Furthermore,
    the Court finds that the FWS, in fact, did not rely exclusively on data relating to the Trout’s
    persistence, but instead used various metrics to assess threats to the Trout, including general
    population health. See Not Warranted Finding, 72 Fed. Reg at 32,596. Finally, the FWS
    addressed in the Not Warranted Finding why it declined to undertake a viability analysis here.
    
    Id. at 32,592
     (stating that the 2006 Range-Wide Status Report was more comprehensive than the
    viability criteria developed to evaluate Rio Grande cutthroat trout).
    Because the FWS has provided a reasoned explanation of its methodology, the
    Court will not second-guess its decision to forego a Rio Grande cutthroat trout-style viability
    analysis. “Judicial ‘deference to the agency is greatest when reviewing technical matters within
    its area of expertise, particularly its choice of scientific data and statistical methodology.’” Fund
    for Animals v. Babbitt, 
    903 F. Supp. 96
    , 114 (D.D.C. 1995) amended, 
    967 F. Supp. 6
     (D.D.C.
    1997) (quoting State of Louisiana ex rel. Guste v. Verity, 
    853 F.2d 322
    , 329 (5th Cir. 1988)).
    Although the plaintiffs may disagree with the science or the methodology the FWS elects to use,
    absent a statutory mandate that requires a particular methodology, the agency’s choice of
    26
    methodology need only be “reasonable” to be upheld. See Am. Wildlands v. Kempthorne, 
    530 F.3d at 998-99
    .
    Finally, plaintiffs claim that the FWS failed to follow its own peer review
    procedures, contrary to the ESA’s requirement to rely on the best available science. Plaintiffs
    point to the FWS’s Peer Review Policy, which provides that the FWS will solicit “[i]ndependent
    peer review . . . on listing recommendations.” Pls.’ Mot. Summ. at 33 (citing Notice of
    Interagency Cooperative Policy for Peer Review in Endangered Species Act Activities, 
    59 Fed. Reg. 34,270
    , 34,270 (July 1, 1994)). Although the 2006 Range-Wide Status Report was peer-
    reviewed, plaintiffs argue that this does not satisfy the FWS’s obligation to conduct an
    independent peer review of the Finding itself. As this Court has previously found, however, the
    FWS’s peer review policy “is not an APA promulgated regulation of the sort held to be
    enforceable against an agency.” Building Industry of Superior California v. Babbitt, 
    979 F. Supp. at 905
    . The FWS’s listing decision “cannot be overturned based on the FWS’s alleged
    noncompliance with its own, nonbinding policy statements.” Id.
    6. Erroneous Analysis of the Evidence in the Record
    Plaintiffs’ remaining arguments go the FWS’s scientific conclusions about the
    state of the Trout. The Supreme Court has made clear that where a determination “requires a
    high level of technical expertise, [a court] must defer to the informed discretion of the
    responsible federal agencies.” Marsh v. Oregon Natural Res. Council, 
    490 U.S. at
    377 (citing
    Kleppe v. Sierra Club, 
    427 U.S. 390
    , 412 (1976)). Nonetheless, “the presumption of agency
    expertise may be rebutted if its decisions, even though based on scientific expertise, are not
    27
    reasoned.” Defenders of Wildlife v. Babbitt, 958 F. Supp. at 679 (citing ALLTEL Corp. v. FCC,
    
    838 F.2d 551
    , 562 (D.C. Cir. 1988)).
    Plaintiffs assert that the FWS’s analysis of the listing factors is contradicted by the
    record and therefore is arbitrary and capricious. In particular, plaintiffs focus on the negative
    effects of various land use activities and the habitat quality rankings, and the FWS’s “improper”
    assessment of the “seriousness of small population size and isolation.” Pls.’ Mot. Summ. at
    25-26.
    In the Not Warranted Finding, however, the FWS provided a lengthy analysis of
    “Fragmentation and Isolation of Small [Trout] Populations in Headwater Areas” under Factor E,
    finding that the problems associated with small isolated populations (“increased risk of
    extirpation by catastrophic events and the loss of genetic exchange”) were mitigated by the
    Trout’s “widespread geographic distribution.” Not Warranted Finding, 72 Fed. Reg at 32,596;
    see also id. at 32,587 (discussing the benefits of isolated populations, which are “less susceptible
    to introgression and competition from nonnative fish”). The FWS addressed the threat of land
    use activities on Trout survival through its examination of habitat quality for currently occupied
    habitat, id. at 32,592, and reasonably noted that “the mere presence of an activity within a stream
    segment that hosts a conservation population is not sufficient evidence to conclude that the
    population is threatened.” 72 Fed. Reg at 32,593. The Service also observed that other factors
    “such as distribution and abundance, and recent trends” must be considered when determining
    the vulnerability of a population. Id. (“Otherwise, logic would dictate that every species that
    comes into contact with managed landscapes is threatened by those human influences.”).
    28
    In light of the FWS’s reasoned explanation, its support in the Administrative
    Record, and the deference afforded to the agency’s scientific findings, the Court cannot say that
    the agency’s conclusions about the threats facing the Trout are unreasonable or contradicted by
    the record.
    *    *   *
    In sum, the plaintiffs have not shown that the FWS acted in an arbitrary and
    capricious manner, abused its discretion, or otherwise acted in violation of the statute, in finding
    that listing the Colorado River cutthroat trout as “threatened” or “endangered” under the
    Endangered Species Act is not warranted at this time. The Court finds that the FWS has adopted
    a reasonable interpretation of the statute and provided adequate explanations for its decision, and
    that the record does not contradict the agency’s factual findings or methodological choices.
    B. Claim 2: Legal Memorandum from the Solicitor of the Department of the Interior
    Plaintiffs’ second claim presents a facial challenge to the Solicitor’s
    Memorandum analyzing the meaning of the phrase “significant portion of its range” in the
    Endangered Species Act, which plaintiffs contend heavily influenced the Not Warranted Finding
    challenged in the first claim. Plaintiffs allege that the Solicitor’s Memorandum violated the plain
    meaning of the ESA, and that it was issued in violation of the ESA’s notice and comment
    procedures.
    The FWS initially filed a motion to dismiss the second claim for failure to state a
    claim, arguing that the memorandum was not a final agency action and therefore was not
    judicially reviewable. On May 5, 2011, however, the current Solicitor of the Interior formally
    withdrew the Memorandum in its entirety. See Federal Defendants’ Notice Regarding
    29
    Withdrawal of Solicitor’s Opinion [Docket No. 37].8 The Solicitor announced that the FWS
    intended to develop new guidance on how to apply the “significant portion of its range” phrase in
    its listing decisions, id., and it initiated the process by which to do so in December 2011.9 The
    briefing on defendants’ motion to dismiss was incorporated into the summary judgment briefing,
    in which the plaintiffs argued that this Court retained jurisdiction to review the Memorandum’s
    legality, and defendants argued that plaintiffs’ second claim should be dismissed as moot.
    The Court agrees with defendants and finds that it must dismiss as moot the
    plaintiffs’ challenge to the withdrawn Solicitor’s Memorandum, as this Court cannot order any
    relief that the agency has not already provided.
    Federal courts only have jurisdiction over “cases” and “controversies.” U.S.
    Const. art. III, § 2, cl. 1. Consequently, they can resolve only “real and substantial
    controvers[ies] admitting of specific relief through a decree of a conclusive character[.]”
    Pharmachemie B.V. v. Barr Labs., Inc., 
    276 F.3d 627
    , 631 (D.C. Cir. 2002) (alterations in
    original) (quoting Lewis v. Cont’l Bank Corp., 
    494 U.S. 472
    , 477 (1990)). A federal court must
    dismiss a claim as moot whenever “events have so transpired that the decision will neither
    presently affect the parties’ rights nor have a more-than-speculative chance of affecting them in
    the future.” 
    Id.
     (quoting Clarke v. United States, 
    915 F.2d 699
    , 701 (D.C. Cir. 1990)).
    8
    The withdrawal occurred after at least two district courts rejected an application,
    not relevant here, of the Solicitor’s interpretation. See Defenders of Wildlife v. Salazar, 
    729 F. Supp. 2d 1207
     (D. Mont. 2010) (rejecting FWS’s listing of wolves only in one state); WildEarth
    Guardians v. Salazar, CV-09-0574, 
    2010 WL 3895682
     (D. Ariz. 2010) (rejecting FWS’s
    conclusion that prairie dog species warranted listing only through specific region).
    9
    The Department of the Interior has proposed a new rule through notice-and-
    comment rulemaking procedures. See Draft Policy on Interpretation of the Phrase “Significant
    Portion of Its Range” in the Endangered Species Act’s Definitions of “Endangered Species” and
    “Threatened Species”. 
    76 Fed. Reg. 76,987
     (Dec. 9, 2011).
    30
    Plaintiffs, citing the “voluntary cessation” exception to the mootness doctrine,
    claim that the Court should not dismiss this claim. “‘It is well settled that a defendant's voluntary
    cessation of a challenged practice does not deprive a federal court of its power to determine the
    legality of the practice[.]’” Fund for Animals, Inc. v. U.S. Bureau of Land Mgmt., 
    460 F.3d 13
    ,
    25-26 (D.C. Cir. 2006) (citing Worth v. Jackson, 
    451 F.3d 854
    , 860 (D.C. Cir. 2006)). A claim
    challenging a voluntarily ceased practice is only moot when “(1) there is no reasonable
    expectation that the conduct will recur and (2) interim relief or events have completely and
    irrevocably eradicated the effects of the alleged violation.” Qassim v. Bush, 
    466 F.3d 1073
    , 1075
    (D.C. Cir. 2006) (quoting Motor & Equip. Mfrs. Assn v. Nichols, 
    142 F.3d 449
    , 459 (D.C. Cir.
    1998)) (quotation marks omitted). Therefore, a claim challenging a ceased practice is not moot if
    the practice is likely to recur or if the relief sought remains available.
    As the Supreme Court has said, “a defendant claiming that its voluntary
    compliance moots a case bears the formidable burden of showing that it is absolutely clear the
    allegedly wrongful behavior could not reasonably be expected to recur.” Friends of the Earth,
    Inc. v. Laidlaw Envtl. Servs. (TOC), Inc., 
    528 U.S. 167
    , 190 (2000); see also Am. Bar Assn v.
    FTC., 
    636 F.3d 641
    , 648 (D.C. Cir. 2011). Nevertheless, there must be “some cognizable danger
    of recurrent violation, something more than the mere possibility which serves to keep the case
    alive.” Air Line Pilots Assn Intern. v. Northwest Airlines, Inc., 
    199 F.3d 477
    , 486 (D.C. Cir.
    1999) (quoting United States v. W.T. Grant Co., 345 U.S. at 632-33). Whether a practice is likely
    to recur is a factual matter. See Friends of the Earth, Inc. v. Laidlaw Envtl. Servs. (TOC), Inc.,
    
    528 U.S. at 193
    .
    31
    Plaintiffs assert that it is reasonably likely that the FWS’s new interpretation of
    “significant portion of its range” will be the same as the one stated in the withdrawn
    memorandum, but this assertion is not based on any actions or statements by the defendant. See
    Nat’l Assn of Home Builders v. Salazar, 
    827 F. Supp. 2d 1
    , 6 (D.D.C. 2011) (considering
    whether withdrawal mooted a home builders’ association’s facial challenge to the
    Memorandum’s validity and finding “no reasonable expectation that the conduct will recur”).
    The defendants here have not engaged in a pattern of illegal conduct or indicated that they will
    reinstate the challenged policy when litigation ends. Instead, they have announced their intention
    to develop a new policy in accordance with the ESA and initiated a transparent rulemaking
    process, which is not yet complete.10
    Plaintiffs incorrectly assert that injunctive and declaratory relief is still available.
    Although plaintiffs seek to have this Court vacate other listing decisions that relied on the
    Solicitor’s Memorandum, challenges to the FWS’s use of the legal interpretations in that
    memorandum are properly brought through individual actions seeking review of specific listing
    decisions, as the first claim was brought here. Plaintiffs also contend that this Court may issue
    declaratory relief by declaring incorrect the legal analysis contained in the Solicitor’s
    Memorandum. This Court, however, refuses to issue an impermissible advisory opinion, whose
    only effect would be to constrain the FWS’s reinterpretation of the phrase in the future. See Flast
    10
    Plaintiffs unpersuasively argue that this case is similar to Defenders of Wildlife v.
    Salazar, 
    842 F. Supp. 2d 181
     (D.D.C. 2012), in which Judge Kessler found that a challenge to
    agency regulations was not mooted by the cancellation of agency agreements made under that
    regulation. In that case, however, the challenged agency action (the regulations) remained in
    effect, whereas here the challenged agency action (the Solicitor’s Memorandum) has been
    withdrawn.
    32
    v. Cohen, 
    392 U.S. 83
    , 96 (1968) (“[T]he oldest and most consistent thread in the federal law of
    justiciability is that the federal courts will not give advisory opinions.”). Accordingly, plaintiffs’
    second claim is dismissed as moot.
    IV. CONCLUSION
    For the reasons set forth above, and in accordance with the Order issued
    September 28, 2012, the Court grants the defendants’ motion to dismiss plaintiffs’ second claim,
    albeit on different grounds than those first proposed in defendants’ motion, grants the
    defendants’ motion for summary judgment with respect to plaintiffs’ first claim, and denies
    plaintiffs’ motion for summary judgment.
