    SUMMARY *
    Environmental Law
    In a case in which intervenor Rosemont Copper
    Company challenges the U.S. Fish and Wildlife Services’s
    (FWS) designation of certain areas in southern Arizona as
    critical habitat for jaguar under the Endangered Species Act
    (ESA), the panel affirmed the district court’s vacatur of the
    FWS’s designation of the challenged area as occupied
    critical habitat; reversed the district court’s grant of
    summary judgment in favor of the FWS regarding its
    designation of that same area and of Subunit 4b as
    unoccupied critical habitat; vacated the grant of summary
    judgment in favor of the Center for Biological Diversity
    (Center); and remanded with directions that the case be
    returned to the agency for further proceedings.
    This litigation was initiated by the Center after the FWS
    concluded that Rosemont’s proposed mine project would not
    destroy or adversely modify the designated critical
    habitat. Rosemont intervened and filed crossclaims against

    the FWS, arguing that certain of its critical-habitat
    designations for the jaguar violated the Administrative
    Procedures Act (APA) and the ESA. This case concerns
    only Unit 3, which covers 351,501 acres and spans several
    counties and mountain ranges, including the Santa Rita
    Mountains; and Subunit 4b, which covers 12,710 acres and
    is a corridor connecting the Whetstone Mountains and the
    Santa Rita Mountains.
    The FWS argued that the district court erred in rejecting
    the FWS’s designation of Unit 3 as occupied critical habitat,
    and Rosewood argued that the district court erred in
    upholding the FWS’s designation of Unit 3 and Subunit 4b
    as unoccupied critical habitat because the standard the FWS
    used was something less demanding than essential for the
    conservation of species. First, the panel held that the only
    plausible construction of “essential” in the ESA’s definition
    of “critical habitat” is area that is indispensable or necessary
    to conservation, not merely beneficial to such
    efforts. Second, the panel considered whether the FWS’s
    critical habitat designations of Unit 3 and Subunit 4b were
    proper. Because the FWS designated the northern Santa Rita
    Mountains as occupied critical habitat based on irrelevant
    photographs from decades after the jaguar was listed as
    endangered and a single timely sighting from a different
    mountain range, the panel affirmed the district court’s
    conclusion that the FWS’s challenged occupied critical-
    habitat designation was arbitrary and capricious.
    Next, the panel addressed Rosemont’s argument that the
    FWS failed to follow its regulation governing unoccupied
    critical-habitat designations. This court discussed the
    operative version of 
    50 C.F.R. § 424.12
    (e) in Bear Valley
    Mut. Water Co. v. Jewell, 
    790 F.3d 977
     (9th Cir. 2015). The
    FWS and the Center argued that Bear Valley foreclosed
    4          CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    Rosemont’s argument that the FWS erred by not sequentially
    considering both adequacy and essentiality. The panel held
    that imposing a sequential analysis to determine whether
    designation of unoccupied critical habitat is proper does not
    violate Bear Valley, which acknowledged both the
    inadequacy-of-occupied-habitat        and     essentiality-of-
    unoccupied-habitat requirements and upheld the FWS’s
    challenged designation where these requirements were both
    met. Because the panel concluded that Bear Valley did not
    displace the agency’s interpretation of Section 424.12(e), the
    panel considered whether the FWS’s designation of Unit 3
    and Subunit 4b as unoccupied critical habitat complied with
    Section 424.12, as interpreted by the agency.
    The panel held that because the FSW did not comply
    with Section 424.12(e) by addressing whether designated
    occupied critical habitat was adequate to address
    conservation goals, its designation of Unit 3 and Subunit 4b
    as unoccupied critical habitat was arbitrary and
    capricious. The panel rejected the dissent’s position that the
    FWS could properly consider the adequacy of areas
    occupied at the time of designation not just the time of listing
    in deciding whether designation of unoccupied areas was
    essential. The panel agreed with the Tenth Circuit that the
    governing version of Section 424.12 required the FWS to
    consider a species range at the time of listing because any
    other reasoning would be inconsistent with the ESA. The
    panel held further that even if the FWS should consider
    whether areas occupied at the time of designation, rather
    than listing, were inadequate to conserve the species, the
    FWS’s analysis still fell short because it did not explain why
    the areas that it found were occupied when it made its
    unoccupied critical habitat designations were inadequate to
    conserve the jaguar. The panel concluded that the FWS did
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS          5
    not provide a rational connection between the facts found
    and the choice made, or articulate a satisfactory explanation
    to justify its designations of Unit 3 and Subunit 4b as
    unoccupied critical habitat.
    Finally, Rosemont challenged the district court’s refusal
    to remand for reconsideration of the FWS’s economic-
    impact analysis. The panel held that Rosemont had not
    waived this issue. Rosemont’s argument that the FWS
    needed to revisit its economic-impact analysis became
    relevant only after the district court concluded that the FWS
    used the wrong standard in determining that Rosemont’s
    Mine would not adversely affect the designated critical
    habitat and remanded for the FWS to reconsider that
    issue. Thus, it was not improper for Rosemont to raise the
    argument for the first time on appeal. The panel held,
    however, that directing the FWS to reconsider its economic-
    impact analysis was premature at this point.
    The panel concluded that it need not reach whether the
    FWS violated the APA in concluding that Rosemont’s Mine
    would not adversely modify the Unit 3 and Subunit 4b
    critical-habitat designations, which the Center argued in its
    motion for summary judgment.
    Concurring in part and dissenting in part, Judge H.A.
    Thomas agreed with the majority that the district court
    correctly vacated the FWS’s designation of Unit 3 as
    occupied critical habitat. She also agreed it would be
    premature to vacate the FWS’s economic-impact
    analysis. She dissented from the majority’s holding that the
    district court erred in upholding the FWS’s designation of
    Unit 3 and Subunit 4b as unoccupied critical habitat. She
    would hold that, when considered as a whole, the record
    amply supported the FWS’s determination that habitat
    6          CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    within the United States—and the designated units in
    particular—were critical to the conservation of the jaguar as
    it faces threats elsewhere in its range.

    OPINION
    FORREST, Circuit Judge:
    Rosemont Copper Company (Rosemont) challenges the
    U.S. Fish and Wildlife Service’s (FWS) designation of
    certain areas in southern Arizona as critical habitat for jaguar
    under the Endangered Species Act (ESA). Rosemont seeks
    to develop a copper mine and related processing facilities in
    the area within and adjacent to the critical-habitat
    designations. This litigation was initiated by the Center for
    Biological Diversity (Center) after the FWS concluded that
    Rosemont’s proposed mine project would not destroy or
    adversely modify the designated critical habitat. The Center
    alleged that the FWS and the United States Forest Service
    violated the Administrative Procedures Act (APA) in
    approving Rosemont’s proposed mining project. Rosemont
    intervened and filed crossclaims against the FWS, arguing
    that certain of its critical-habitat designations for the jaguar
    violated the APA and the ESA. All parties moved for
    summary judgment.
    The district court concluded that the FWS erred in
    designating occupied critical habitat in the northern Santa
    Rita Mountains because the record did not establish that
    jaguar occupied this area when this species was listed as
    endangered in 1972. Ctr. for Biological Diversity v. U.S.
    Fish & Wildlife Serv., 
    441 F. Supp. 3d 843
    , 872 (D. Ariz.
    2020). But it upheld the FWS’s designation of this same area
    and an adjacent area as unoccupied critical habitat. 
    Id.
     at
    872–73. The district court also granted summary judgment
    in favor of the Center on its claim that the FWS violated the
    APA by improperly using a heightened standard in
    determining that Rosemont’s mining project was not likely
    8             CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    to destroy or adversely modify designated critical habitat for
    the jaguar and remanded for the FWS to conduct a proper
    analysis. 
    Id.
     at 855–57. Rosemont argues that if this case is
    remanded, the FWS should be instructed to reconsider its
    economic-impact analysis that was part of the basis for its
    critical-habitat designation. We conclude that the district
    court correctly vacated the FWS’s occupied critical-habitat
    designation but erred in upholding the FWS’s unoccupied
    critical-habitat designations. Therefore, we reverse the grant
    of summary judgment in favor of the FWS, vacate the grant
    of summary judgment in favor of the Center, remand with
    instructions for the district court to vacate the FWS’s
    critical-habitat designations, and remand to the agency for
    further proceedings consistent with this opinion.
    I. BACKGROUND
    A. The Endangered Species Act
    The ESA is “the most comprehensive legislation for the
    preservation of endangered species ever enacted by any
    nation.” Tennessee Valley Auth. v. Hill, 
    437 U.S. 153
    , 180
    (1978). It directs the Secretary of the Interior to “determine
    whether any species is an endangered species or a threatened
    species.” 1 
    16 U.S.C. § 1533
    (a)(1). The Secretary publishes
    in the Federal Register “a list of all species determined . . .
    to be endangered species and a list of all species determined
    1
    A “species” includes “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.” 
    16 U.S.C. § 1532
    (16). An
    “endangered species” is “any species which is in danger of extinction
    throughout all or a significant portion of its range,” and a “threatened
    species” is “any species which is likely to become an endangered species
    within the foreseeable future throughout all or a significant portion of its
    range.” 
    Id.
     § 1532(6), (20).
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS                    9
    . . . to be threatened species.” Id. § 1533(c)(1). Upon listing
    a species as endangered or threatened, the Secretary is
    required to “concurrently . . . designate any habitat of such
    species which is then considered to be critical habitat.” Id.
    § 1533(a)(3)(A)(i). Critical habitat designations must be
    based on the conditions that existed at the time of listing, id.
    § 1532(5)(A), and “the best scientific data available and after
    taking into consideration the economic impact, . . . national
    security, and any other relevant impact, of specifying any
    particular area as critical habitat.” Id. § 1533(b)(2).
    B. The Jaguar
    The jaguar (Panthera onca) is a large felid found in
    South America, Central America, Mexico, and the
    southwestern United States. The jaguar’s total range spans
    over 3 million square miles. The portion of this range in the
    United States is less than one percent. Although “[t]he
    probability of long-term survival of the jaguar is considered
    high in 70 percent of the currently occupied range,” the
    population is decreasing because of many biological
    challenges, including the jaguar’s “large spatial
    requirements.”
    More than 30,000 jaguars likely still live in the wild.
    About 600 of those are found in northwestern Mexico. No
    breeding pair of jaguars has been documented in the relevant
    area of the United States. There are only three undisputed
    records of female jaguars with cubs in the United States––
    the most recent being in 1910. 2 There is a single record of a

    The FWS followed a classification protocol for reports of jaguar present
    in the United States based on the degree of certainty or validity of the
    report. For example, a “Class I record” is substantiated by physical
    10           CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    female jaguar in the United States in 1963, but it is disputed.
    There have been no confirmed sightings of female jaguar in
    the United States since 1963. The FWS identified undisputed
    Class I records of eight or nine unique jaguars (all males)
    within the United States between 1962 and 2013. One of
    these included a jaguar that was shot in southern Arizona in
    1965. “Jaguars in the United States are understood to be
    individuals dispersing north from Mexico . . . where the
    closest breeding population occurs about 210 km (130 mi)
    south of the U.S.-Mexico border.”
    The FWS first listed the jaguar as endangered in 1972.
    The average lifespan of a jaguar is approximately ten years.
    “[T]he jaguar was included only on the foreign species list”
    because the jaguar was believed to be extinct in the United
    States. 3 90-Day Finding on a Petition to Revise Critical
    Habitat for the Jaguar, 
    86 Fed. Reg. 49985
    -01, 49986 (Sept.
    7, 2021). The FWS issued a proposed rule in 1980 to list the
    jaguar as a domestic endangered species, but the proposed
    rule was withdrawn in 1982. The FWS did not list the jaguar
    as an endangered species in the United States until 1997.
    Despite the later designation of the jaguar as a domestic
    evidence (e.g., a skin, skull, or photograph) and considered “‘verified’ or
    ‘highly probable.’” A Class II record has “detailed information of the
    observation,” but no physical evidence and is considered “‘probable’ or
    ‘possible.’” Disputed records include those where “the validity of the[]
    location[] is questionable because of the suspicion that the[] [observed]
    animals were released for ‘canned hunts.’”
    3
    The categorization of the jaguar as an endangered species on the foreign
    species list was in accordance with the Endangered Species Conservation
    Act of 1969 (ESCA), a precursor to the Endangered Species Act of 1973,
    which maintained separate listings for foreign species and species native
    to the United States. See 90-Day Finding on a Petition to Revise Critical
    Habitat for the Jaguar, 
    86 Fed. Reg. 49985
    -01, 49986 (Sept. 7, 2021).
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS        11
    endangered species, the FWS treats its 1972 listing as the
    jaguar’s listing date within the United States because “it was
    always [FWS’s] intent . . . to consider the jaguar endangered
    throughout its entire range when it was listed as endangered
    in 1972.” 4
    The FWS did not designate critical habitat for the jaguar
    when it listed the jaguar as a domestic endangered species in
    1997. The FWS concluded that a critical habitat designation
    in the United States was “not prudent” because “the primary
    threat to [jaguars] in the United States is direct taking rather
    than habitat destruction,” and the “[p]ublication of detailed
    critical habitat maps and descriptions in the Federal Register
    would” be counterproductive. In 2006, the FWS
    reconsidered its decision not to designate critical habitat and
    again decided against making such a designation.
    The FWS changed course on designating critical habitat
    for the jaguar in 2009. That year, the FWS’s 2006
    determination not to designate critical habitat for the jaguar
    was vacated by a federal court. See Ctr. for Biological
    Diversity v. Kempthorne, 
    607 F. Supp. 2d 1078
    , 1094 (D.
    Ariz. 2009). On remand in that litigation, the FWS
    concluded that “the designation of critical habitat for the
    jaguar would be beneficial” to conservation of the species.
    Based on this changed position, the FWS “convened a
    binational Jaguar Recovery Team in 2010.” The team was
    tasked with “synthesiz[ing] information on the jaguar,
    focusing on [a]n area comprising jaguars in the northernmost
    portion of their range.”
    In April 2012, the Jaguar Recovery Team issued a
    “Recovery Outline for the Jaguar.” The Recovery Outline
    4
    Rosemont does not dispute 1972 as the time of listing.
    12         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    divided the jaguar’s range into two “recovery units”: the
    Northwestern Recovery Unit (NRU) and the Pan American
    Recovery Unit. Each unit has “core areas” with “persistent
    verified records of jaguar occurrence over time and recent
    evidence of reproduction.” They also have “secondary
    areas” that “contain jaguar habitat with historical and/or
    recent records of jaguar presence [but] with no recent record
    or very few records of reproduction.” Secondary areas “are
    of particular interest when they occur between core areas and
    can be used as transit areas through which dispersing
    individuals can move, reach adjacent core areas, and
    potentially breed.”
    The Recovery Outline focused on the NRU, which
    contains two core areas and secondary areas.           The
    northernmost section of the NRU—a secondary area that
    extends into Arizona and New Mexico—is the area at issue
    in this case. This section of the NRU does not connect two
    core areas. The area that extends into the United States
    contains approximately 12,386 square miles, which is
    roughly 0.36% of the jaguar’s current range. A map of the
    NRU is included as Appendix 1.
    The Recovery Outline stated that “jaguars in the U.S. are
    thought to be part of a population, or populations, that occur
    largely in Mexico.” And based on the evidence available,
    “any conclusions about the conservation importance of the
    habitat types in which jaguars have occurred or might occur
    in Arizona and New Mexico are preliminary and can vary
    widely.” However, “the region to the south of Arizona and
    New Mexico is especially critical for the recovery of the
    jaguar in the southwestern U.S. because the source
    population is likely in central Sonora[, Mexico].”
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS                  13
    Relying on the Recovery Outline, the FWS published a
    proposed rule in 2012 designating approximately 838,000
    acres in southern Arizona and New Mexico as critical habitat
    for the jaguar. The FWS revised its initial proposal and
    sought additional public comment in 2013. The Arizona
    Game and Fish Department (Arizona) objected to critical
    habitat being designated for the jaguar within that state.
    Specifically, Arizona argued that “designating critical
    habitat for the less than 1% of historic jaguar range which
    occurs in the U.S. would jeopardize the credibility and long-
    term viability of the ESA,” and that “recovery of jaguar is
    entirely reliant on conservation action in the 99+% of its
    habitat found south of the international border.” Rosemont
    also submitted comments that the area within its proposed
    mining project should be excluded from the FWS’s critical-
    habitat designations.
    The FWS published its Final Rule on March 5, 2014
    (Final Rule). See Endangered and Threatened Wildlife and
    Plants; Designation of Critical Habitat for Jaguar, 
    79 Fed. 12572
    , 12573 (Mar. 5, 2014). The Final Rule designated
    764,207 acres in southern Arizona and southwestern New
    Mexico as critical habitat. 
    Id. at 12572
    . The designated area
    includes six units, four located in Arizona (Units 1–4), one
    that straddles the Arizona/New Mexico border (Unit 5), and
    one located in New Mexico (Unit 6). 5

    The Tenth Circuit addressed challenges to the FWS’s designation of
    Units 5 and 6 as critical habitat in New Mexico Farm & Livestock Bureau
    v. United States Department of Interior, 
    952 F.3d 1216
     (10th Cir. 2020).

    Subunit 4b covers 12,710 acres and is a corridor connecting
    the Whetstone Mountains and the Santa Rita Mountains. 
    Id. at 12593
    . A map of Units 1 through 4 is included as
    Appendix 2.
    The FWS explained that in determining the occupancy
    of the jaguar at the time of listing, it was considering
    evidence from 1962 through 1982 (10 years before and after
    the listing date) because the “consensus” is that the average
    lifespan of a jaguar is 10 years. 
    Id. at 12581
    . The FWS
    considered areas in which jaguars had been reported from
    1982 to the present to be occupied given “it is likely those
    areas were occupied at the time of the original listing, but
    jaguars had not been detected because of their rarity, the
    difficulty in detecting them, and a lack of surveys for the
    species.” 
    Id.
     The FWS then determined that Unit 3 was
    “occupied” by jaguar in 1972 and designated this area
    occupied critical habitat. 
    Id. at 12593
    . The FWS based this
    determination on an undisputed Class I record of a jaguar in
    1965, photos of a male jaguar in the Santa Rita Mountains in
    2012 and 2013, and its finding that the mountain ranges
    within Unit 3 contained all the “primary constituent
    elements” (PCEs) for jaguars. 
    Id.

    elements of the physical or biological features that provide
    for a species’ life history processes and are essential to the
    conservation of the species.” 
    Id. at 12587
    . Acknowledging
    uncertainty in its conclusion that Unit 3 was “occupied” at
    listing, the FWS also analyzed whether Unit 3 was properly
    designated as “unoccupied” critical habitat.

    The FWS found that it was because there was evidence of
    recent occupancy in Unit 3, the area contained features that
    constitute jaguar habitat, and the area contributed to the

    C. Rosemont’s Mining Project
    Rosemont’s proposed copper mine and related mineral-
    processing facilities (Mine) are located in the northern Santa
    Rita Mountains in Pima County, Arizona. Applying for the
    necessary federal authorizations and permits for its Mine,
    Rosemont consulted twice with federal agencies on
    endangered-species issues and requirements under the ESA.
    During both consultations, the FWS considered whether
    Rosemont’s Mine was likely to destroy or adversely modify
    the jaguar’s critical habitat that the FWS had designated. The
    FWS issued a biological opinion after each consultation
    (2013 and 2016 Biological Opinion) and concluded both
    times that the Mine was “not likely [to] destroy or adversely
    modify” critical habitat for the jaguar. Accordingly, the FWS
    declined to exclude Rosemont’s project area from its critical-
    habitat designation because “the construction and operation
    of the Rosemont Mine would not . . . adversely modify
    designated critical habitat” and the resulting economic costs
    from the designation, if any, would be limited.
    D. Procedural Background
    In September 2017, the Center sued the FWS, alleging
    that it violated the APA in issuing its 2016 Biological
    Opinion and approving Rosemont’s Mine. Rosemont
    intervened as a defendant and crossclaimed, arguing that the
    FWS violated the ESA and the APA by designating Unit 3
    16           CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    and Subunit 4b as critical habitat for the jaguar. The parties
    cross-moved for summary judgment.
    The district court granted the FWS’s and the Center’s
    motions for summary judgment and denied Rosemont’s
    motion. Ctr. for Biological Diversity, 441 F. Supp. 3d at
    871–75. The district court agreed with Rosemont that the
    FWS erred in determining that Unit 3 was occupied by the
    jaguar when it was listed, but it held that the FWS properly
    designated Unit 3 and Subunit 4b as unoccupied critical
    habitat. Id. at 872–74. The district court also granted
    summary judgment to the Center on its claim that the FWS’s
    2016 Biological Opinion improperly used a heightened
    standard in determining that Rosemont’s Mine was not likely
    to destroy or adversely modify critical habitat for the jaguar.
    Id. at 855–57.
    Rosemont timely appealed. Thereafter, Rosemont
    petitioned the FWS to revise its critical-habitat designations
    to exclude the area where the Mine is located in the northern
    Santa Rita Mountains. 6 We stayed Rosemont’s appeal
    pending the FWS’s ruling on Rosemont’s petition. In
    September 2021, the FWS denied Rosemont’s petition,
    finding that it “does not present substantial scientific or
    commercial information indicating that [the northern portion
    of Unit 3 and Subunit 4b] are not essential for the
    conservation of the species.” 90-Day Finding on a Petition

    Rosemont’s motion requesting that we take judicial notice of its
    Petition to Revise the Critical Habitat for the Jaguar Species, filed with
    the FWS on November 11, 2020, is granted. See Anderson v. Holder, 
    673 F.3d 1089

    II. DISCUSSION
    We review the district court’s summary judgment rulings
    de novo to determine whether the FWS’s challenged actions
    were “arbitrary, capricious, an abuse of discretion, or
    otherwise not in accordance with law.” 
    5 U.S.C. § 706
    (2)(A); Ariz. Cattle Growers’ Ass’n v. Salazar, 
    606 F.3d 1160
    , 1163 (9th Cir. 2010). Agency action is arbitrary and
    capricious when the agency “relie[s] on factors which
    Congress has not intended it to consider, entirely fail[s] to
    consider an important aspect of the problem, [or] offer[s] an
    explanation for its decision that runs counter to the evidence
    before the agency.” Motor Vehicle Mfrs. Ass’n v. State Farm
    Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983); see also
    Michigan v. EPA, 
    576 U.S. 743
    , 750 (2015) (“Not only must
    an agency’s decreed result be within the scope of its lawful
    authority, but the process by which it reaches that result must
    be logical and rational.” (quoting Allentown Mack Sales &
    Serv., Inc. v. NLRB, 
    522 U.S. 359
    , 374 (1998))).
    The first issue for decision is whether the FWS’s
    designations of Unit 3 and Subunit 4b as critical habitat were
    proper. Because we conclude that they were not, we do not
    reach whether the FWS correctly determined that
    Rosemont’s Mine would not adversely affect those
    designated critical habitats, the subject of the Center’s
    motion for summary judgment. We also reject Rosemont’s
    argument that the district court erred by not requiring the
    FWS on remand to reconsider its economic-impact analysis
    related to its critical-habitat designations because that issue
    is premature.

    A. Critical Habitat Designations
    As previously stated, when a species is listed as
    endangered or threatened, the Secretary of the Interior must
    “concurrently . . . designate any habitat of such species
    which is then considered to be critical habitat.” 
    16 U.S.C. § 1533
    (a)(3)(A)(i). Habitat may be designated as critical if it
    is “essential” to the “conservation of the species.” 
    Id.
    § 1532(5)(A). The ESA identifies two types of critical
    habitat: occupied and unoccupied. Id. An area may be
    designated as “occupied” critical habitat if the species is
    present in the area when the species is listed, and the area
    has the “physical or biological features (I) essential to the
    conservation of the species and (II) which may require
    special management considerations or protection.” Id.
    § 1532(5)(A)(i). The species need not be physically present
    permanently for an area to be designated as occupied; the
    area simply must “contain” the species. Ariz. Cattle
    Growers’ Ass’n, 606 F.3d at 1165. Stated another way, an
    area is occupied if the species “uses [it] with sufficient
    regularity that [the species] is likely to be present during any
    reasonable span of time.” Id. Unoccupied areas, or areas
    where the species is not present at listing, can be designated
    as critical habitat only if the Secretary determines “that such
    areas are essential for the conservation of the species.” 
    16 U.S.C. § 1532
    (5)(A)(ii).
    While the ESA requires that both occupied and
    unoccupied areas be “essential” to conservation before they
    can be designated as critical habitat, 
    id.
     § 1532(5)(A)(i)–(ii),
    the standard for designating unoccupied critical habitat is
    “more demanding” than the standard for designating
    occupied critical habitat. Home Builders Ass’n of N. Cal. v.
    U.S. Fish & Wildlife Serv., 
    616 F.3d 983
    , 990 (9th Cir.
    2010). When the FWS made the designations challenged in
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS              19
    this case, its governing regulations instructed that “[t]he
    Secretary shall designate as critical habitat areas outside the
    geographical area presently occupied by a species only when
    a designation limited to its present range would be
    inadequate to ensure the conservation of the species.” 
    50 C.F.R. § 424.12
    (e) (2012) (emphasis added). 7
    The FWS argues that the district court erred in rejecting
    the FWS’s designation of Unit 3 as occupied critical habitat.
    Rosemont argues that the district court erred in upholding
    the FWS’s designation of Unit 3 and Subunit 4b as
    unoccupied critical habitat because the standard the FWS
    used was something less demanding than “essential for the
    conservation of the species.”
    1. Definitions
    Congress did not define “essential” as used in the ESA’s
    “critical habitat” definition. Therefore, we begin by
    identifying its “ordinary or natural meaning.” HollyFrontier
    Cheyenne Ref., LLC v. Renewable Fuels Ass’n, 
    141 S. Ct. 2172
    , 2176 (2021) (citation omitted). There is significant
    agreement about the ordinary meaning of “essential”: it
    refers to something that is indispensable or necessary. See
    American Heritage Dictionary of the English Language
    (1970) (“Of the greatest importance; indispensable”);
    Webster’s New World Dictionary, Second College Edition
    (1970) (“Absolutely necessary; indispensable; requisite”);
    Webster’s Third New International Dictionary (1971)
    (“Necessary, indispensable”); see also Black’s Law
    Dictionary (4th ed. 1968) (“Indispensably necessary;
    important in the highest degree; requisite.”). Where

    In 2016, the agency amended the regulation and recodified it at 
    50 C.F.R. § 424.12
    (b)(2). See 
    50 C.F.R. § 424.12
    (b)(2) (2019).
    20         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    “[v]irtually every dictionary we are aware of” from the time
    the ESA was enacted references the same basic meaning,
    “[w]e have not the slightest doubt that is the meaning that
    the statute intended.” MCI Telecomms. Corp. v. AT&T Co.,
    
    512 U.S. 218
    , 225, 228 (1994).
    This interpretation of “essential” also is bolstered by the
    surrounding statutory text. See, e.g., Weyerhaeuser Co. v.
    U.S. Fish & Wildlife Serv., 
    139 S. Ct. 361
    , 368 (2018)
    (“Statutory language cannot be construed in a vacuum.”
    (alteration and citation omitted)); Yates v. United States, 
    574 U.S. 528
    , 543 (2015) (“[A] word is known by the company
    it keeps . . . .”). Congress used “essential” in defining
    “critical habitat” as geographic areas that are “essential to”
    or “essential for” the “conservation of the species.” 
    16 U.S.C. § 1532
    (5)(A)(i)–(ii). “Critical” means “important or
    essential for determining” and refers to a “state on which the
    issue of things depends.” Webster’s New Twentieth Century
    Dictionary (2d edition 1971); see also Webster’s New World
    Dictionary, Second College Edition (1970) (“[O]f or
    forming a crisis or turning point; decisive”); Webster’s Third
    New International Dictionary (1971) (“[I]ndispensable for
    the weathering, the solution, or the overcoming of a crisis”).
    “Conservation”—the concept that “essential” is
    connected to—is defined in the ESA. 
    16 U.S.C. § 1532
    (3).
    It is “the use of all methods and procedures which are
    necessary to bring any endangered species or threatened
    species to the point at which the measures provided pursuant
    to this Act are no longer necessary.” 
    Id.
     (emphasis added).
    “Necessary” also means “indispensable.” See Webster’s
    New World Dictionary, Second College Edition (1970)
    (“[T]hat cannot be dispensed with; essential;
    indispensable.”); American Heritage Dictionary of the
    English Language (1970) (“Needed to achieve a certain
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS            21
    result; requisite”). Taken together, both the accepted plain
    meaning of “essential” and the relevant surrounding
    statutory terms in the ESA unambiguously establish that for
    an area to be “essential” for conservation of a species, it must
    be more than beneficial; rather, the agency must determine
    that the species cannot be brought “to the point at which the
    measures provided pursuant to [the ESA] are no longer
    necessary” without the critical habitat designation. 
    16 U.S.C. § 1532
    (3).
    Caselaw also supports this interpretation. In
    Weyerhaeuser, the Supreme Court construed the ESA’s
    definition of “critical habitat”—whether occupied or
    unoccupied—as including only “areas that are indispensable
    to the conservation of the endangered species.” 
    139 S. Ct. at
    368–69 (emphasis added). And we previously indicated that
    “essential” means indispensable when we affirmed a district
    court’s conclusion that “[i]f certain habitat is essential, it
    stands to reason that if the [FWS] did not designate this
    habitat, whatever the [FWS] otherwise designated would be
    inadequate,” Bear Valley Mut. Water Co. v. Salazar,

    Indeed, while the parties disputed the meaning of
    “essential” in the district court, Ctr. for Biological Diversity,
    441 F. Supp. 3d at 872–74, they seem to now agree that it
    means “indispensable,” “necessary,” and “something more
    than convenient or helpful.” But that is where their
    agreement ends. The FWS and the Center argue that
    “essential” is nonetheless a “broad standard” because it is
    used in reference to “conservation,” which is a broad
    concept. And Rosemont argues that the FWS’s and the
    Center’s proposed interpretation is a “watered-down
    standard that contravenes the plain meaning of the ESA.”
    The FWS and the Center rely on our prior decisions
    recognizing that “the purpose of establishing ‘critical
    habitat’ is for the government to carve out territory that is
    not only necessary for the species’ survival but also essential
    for the species’ recovery.” Gifford Pinchot Task Force v.

    The district court relied on this statement in Home Builders Association

    Home Builders Ass’n of N. Cal., 
    616 F.3d at 989
    ). In Home Builders
    Association, the plaintiff made the “perverse” argument that our
    statement in Gifford Pinchot that “the purpose of establishing critical
    habitat is . . . to carve out territory that is not only necessary for the
    species’ survival but also essential for the species’ recovery” required
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS                  23
    Center argue that Unit 3 and Subunit 4b are “essential for
    jaguar conservation” because “protecting these areas
    through the ESA’s consultation process will promote jaguar
    recovery.”
    This argument is unpersuasive. While “conservation”
    encompasses both ensuring species’ survival and recovery,
    the ESA nonetheless requires the agency to show that
    designation of critical habitat is “necessary” or
    “indispensable” in accomplishing these objectives, not
    merely “beneficial” to or capable of “promoting” survival or
    recovery. Congress not only limited “conservation” to
    include those “methods and procedures which are necessary
    to bring any endangered species or threatened species to the
    point at which the measures provided pursuant to this Act
    are no longer necessary,” 
    16 U.S.C. § 1532
    (3) (emphasis

    habitat areas for protection to only “critical habitat,” which
    it defined as areas “essential” for conservation. 
    Id.
     §
    1532(5)(A). The “extremely broad[]” construction that the
    FWS, the Center, and the dissent advance reads out of the
    statute Congress’ limiting words: “critical,” “essential,” and
    “necessary.” See 
    16 U.S.C. § 1532
    (3), (5)(A). But our
    obligation is to give effect to all the terms of the statute.

    616 F.3d at
    988–89 (quoting Gifford Pinchot,
    378 F.3d at 1070). In responding to this argument, we explained that
    Gifford Pinchot emphasized the dual survival and recovery purposes of
    critical-habitat designations, which “requires FWS to be more generous”
    in defining critical habitat, as opposed to more restrictive. Id. This
    context makes clear that we were not opining about the meaning of
    “essential” or suggesting that nonessential areas could be designated as
    critical habitat for accomplishing the dual purposes of designating
    critical habitat.

    Ysleta Del Sur Pueblo v. Texas, 
    142 S. Ct. 1929

    (2022). And doing so here means that the only plausible
    construction of “essential” in the ESA’s definition of
    “critical habitat” is area that is indispensable or necessary to
    conservation, not merely beneficial to such efforts.
    2. FWS’s Designations
    We now turn to whether the FWS’s critical habitat
    designations of Unit 3 9 and Subunit 4b were proper.
    a. Occupied Critical Habitat
    The district court concluded that the FWS’s designation
    of Unit 3 was arbitrary and capricious because the FWS
    considered evidence of occupancy outside the timeframe of
    1962–1982, which was counter to Congress’s intention that
    the agency consider occupancy at the time of listing. Ctr. for
    Biological Diversity, 441 F. Supp. 3d at 872. The FWS
    contends that this was error.
    For land to be classified as occupied critical habitat, it
    must be “within the geographical area occupied by the
    species, at the time [the species] is listed.” 
    16 U.S.C. § 1532
    (5)(A)(i). Although the ESA and its implementing
    regulations do not define “occupied,” we have previously
    construed this term to refer to when a species “uses [the area]
    with sufficient regularity that it is likely to be present during
    any reasonable span of time.” Ariz. Cattle Growers’ Ass’n,
    606 F.3d at 1165. This is a “highly contextual and fact-
    dependent inquiry.” Id. at 1164.
    9
    Rosemont contests the occupancy determination only as to the northern
    Santa Rita Mountains area of Unit 3—roughly 50,000 of the total
    300,000 acres within Unit 3—and we limit our analysis to only this
    disputed portion.
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS          25
    The FWS designated Unit 3 as “occupied” based on a
    Class I sighting in the Patagonia Mountains in 1965 and
    photographs of a single male jaguar in the Santa Rita
    Mountains taken in 2012 and 2013. Final Rule, 79 Fed. Reg.
    at12593. Because the jaguar was listed as endangered in
    1972 and the average lifespan of a jaguar is ten years, it was
    reasonable for the FWS to consider sightings between 1962
    and 1982, including the Class I sighting from 1965.
    However, we agree with the district court that the FWS’s
    reliance on the 2012 and 2013 photographs was “counter to
    Congress’ intention that the agency consider occupancy at
    the time of listing, not at the time of designation or some
    undefined period.” Ctr. for Biological Diversity, 441 F.
    Supp. 3d at 872.
    The ESA makes clear that the FWS must designate
    critical habitat based on the occupancy status “at the time
    [the species] is listed.” 
    16 U.S.C. § 1532
    (5)(A)(i) (emphasis
    added). Thus, by relying on the 2012 and 2013 photographs,
    taken decades after listing, in designating Unit 3 as occupied
    critical habitat, the FWS “relied on factors which Congress
    has not intended it to consider.” See Motor Vehicle Mfrs.
    Ass’n, 
    463 U.S. at 43
    . Our limited role under arbitrary and
    capricious review does not extinguish our duty to “ensure
    that agency decisions are founded on a reasoned evaluation
    of the relevant factors.” Marsh v. Or. Nat. Res. Council, 
    490 U.S. 360
    , 378 (1989) (internal quotation marks omitted).
    Where the ESA expressly instructs the FWS to focus its
    inquiry on the time of a species’ listing, evidence falling
    outside a reasonable definition of that timeframe is not a
    “relevant factor.” 
    Id.
    Without the 2012 and 2013 photographs, the only
    evidence underlying the FWS’s occupancy determination is
    the Class I sighting from 1965. The FWS argues this alone
    26         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    was enough to establish occupancy and that the district court
    did not adequately consider this evidence. We disagree. The
    district court considered the 1965 sighting and found it an
    “insufficient” basis to conclude that the jaguar occupied the
    northern Santa Rita Mountains, the only portion of the Unit
    3 critical-habitat designation that Rosemont contests. Ctr.
    for Biological Diversity, 441 F. Supp. 3d at 872. The 1965
    sighting was in the Patagonia Mountains. The district court
    was correct that this single sighting in a different mountain
    range has limited relevance to whether the area where
    Rosemont’s Mine is located was occupied by the jaguar in
    1972. Id. This evidence alone does not support the finding
    that the jaguar used the challenged area “with sufficient
    regularity that it is likely to be present during any reasonable
    span of time.” Ariz. Cattle Growers’ Ass’n, 606 F.3d at 1165;
    Turtle Island Restoration Network v. U.S. Dep’t of Com.,
    
    878 F.3d 725
    , 732 (9th Cir. 2017) (holding that agency
    action is arbitrary and capricious when the agency’s
    “explanation for its decision . . . runs counter to the evidence
    before the agency” (citation omitted)).
    The FWS attempts to justify this occupied critical-
    habitat designation based on the circumstances surrounding
    its decision, including the difficulty of detecting jaguars
    during the 1970s and the presence of PCEs in Unit 3. But
    detection difficulties and the existence of favorable
    “physical or biological features” do not speak to whether
    jaguars occupied the disputed area in 1972. See N.M. Farm
    & Livestock Bureau, 952 F.3d at 1227. While jaguars are
    difficult to detect, without a Class I report or some other
    compelling evidence from the relevant period in the relevant
    place, much of the FWS’s decision rests on speculation. See
    id. (“[T]he Service’s reliance on sightings in 1995, 1996, and
    2006 to support a conclusion of occupation in 1972 is not
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS          27
    based on expert opinion and is purely speculative.”). This is
    particularly true where the record otherwise establishes only
    minimal presence of the jaguar in the American Southwest
    generally.
    In sum, because the FWS designated the northern Santa
    Rita Mountains as occupied critical habitat based on
    irrelevant photographs from decades after the jaguar was
    listed as endangered and a single timely sighting from a
    different mountain range, we affirm the district court’s
    conclusion that the FWS’s challenged occupied critical-
    habitat designation was arbitrary and capricious.
    b. Unoccupied Critical Habitat
    The FWS designated Unit 3 and Subunit 4b as
    unoccupied critical habitat. Before turning to the merits of
    these designations, we address Rosemont’s argument that
    the FWS failed to follow its regulation governing
    unoccupied critical-habitat designations.
    i.
    When the FWS issued the Final Rule that included its
    challenged critical-habitat designations, its governing
    regulation provided: “The Secretary shall designate as
    critical habitat areas outside the geographical area presently
    occupied by a species only when a designation limited to its
    present range would be inadequate to ensure the
    conservation of the species.” 
    50 C.F.R. § 424.12
    (e) (2012).
    Rosemont argues that this regulation imposes a two-step
    analysis. First, the FWS must determine that any occupied
    critical habitat is inadequate to conserve the jaguar. And
    second, the FWS must determine that designation of
    unoccupied critical habitat is essential for conservation.
    28         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    The history of Section 424.12(e) is relevant to
    Rosemont’s argument. Section 424.12 was first promulgated
    in 1980. See 
    45 Fed. Reg. 13010
    -01, 13023 (Feb. 27, 1980).
    Up until 2016, including when the FWS issued the 2014
    Final Rule, subsection (e) of the regulation read as just
    quoted—unoccupied critical habitat designations were
    allowed only when occupied critical habitat “would be
    inadequate to ensure the conservation of the species.” 
    50 C.F.R. § 424.12
    (e) (2012); see Final Rule, 79 Fed. Reg. at
    12590. But the agency removed subsection (e) in 2016. 
    81 Fed. 7414
    -01, 7439–40 (Feb. 11, 2016). In the preamble to
    this regulatory amendment, the FWS explained that it was
    stepping away from a “rigid” two-step analysis, “i.e., first
    designating all occupied areas that meet the definition of
    ‘critical habitat’ (assuming that no unoccupied habitat is
    designated) and then, only if that is not enough, designating
    essential unoccupied habitat” because that “may not be the
    best conservation strategy for the species.” 
    Id. at 7415
    . Then
    in 2019, the FWS restored the language previously contained
    in subsection (e). 
    84 Fed. Reg. 45020
    , 45053 (Aug. 27,
    2019). Noting that the 2016 amendment “eliminat[ed] the
    sequenced approach to considering occupied habitat before
    unoccupied habitat,” the FWS stated that it was “restoring
    the requirement that the Secretary will first evaluate areas
    occupied by the species.” 
    Id. at 45043
    .
    We discussed the operative version of Section 424.12 in
    Bear Valley. 
    790 F.3d at 993
    . There, the plaintiffs argued
    that the FWS failed to consider both whether occupied
    habitat areas were adequate for conservation and whether
    unoccupied habitat areas were essential for conservation. 
    Id. at 994
    . At issue there was conservation of sucker fish and the
    FWS’s designation as unoccupied critical habitat upstream
    areas that were “the primary sources of high quality course
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS           29
    sediment for the downstream occupied portions” of the river.
    
    Id.
     The FWS found that the upstream unoccupied sediment
    areas were essential because they provided spawning and
    feeding grounds and helped maintain water quality and
    temperature. 
    Id.
     In rejecting the plaintiffs’ argument that the
    FWS failed to consider the adequacy of the occupied areas
    in meeting conservation objectives, we reasoned that the
    regulation’s reference to adequacy was just the ESA’s
    requirement that an area be “essential” to conservation,
    stated “in a different way.” 
    Id.
     We further explained that in
    that case the FWS’s “Final Rule sufficiently explained why
    the designation of unoccupied habitat . . . was essential, and
    conversely, why designation of solely occupied habitat was
    inadequate for the conservation of the species.” 
    Id.
    The FWS and the Center argue that Bear Valley
    forecloses Rosemont’s argument that the FWS erred by not
    sequentially considering both adequacy and essentiality.
    Rosemont contends that we are not constrained by Bear
    Valley because the agency’s later amendments to Section
    424.12 establish that the 2012 version of the regulation
    mandated a “rigid step-wise approach,” see 81 Fed. Reg. at
    7415; 84 Fed. Reg. at 45043, and that interpretation
    supersedes Bear Valley under National Cable &
    Telecommunications Association v. Brand X Internet
    Services. 
    545 U.S. 967
     (2005).
    Under Brand X, “[a] court’s prior judicial construction
    of a statute trumps an agency construction otherwise entitled
    to Chevron deference only if the prior court decision holds
    that its construction follows from the unambiguous terms of
    the statute and thus leaves no room for agency discretion.”
    
    Id. at 982
    . We conclude that Brand X is not implicated here
    because our decision in Bear Valley does not conflict with
    the FWS’s interpretation of Section 424.12(e). See Medina-
    30         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    Nunez v. Lynch, 
    788 F.3d 1103
    , 1105 (9th Cir. 2015) (noting
    that Brand X is implicated where “we confront a conflict
    between our own precedent and [an agency’s] later
    published precedent to the contrary.”). In Bear Valley, we
    did not reject the requirement that occupied habitat areas
    must be inadequate for conservation before an unoccupied
    critical-habitat designation is proper. Rather, we upheld the
    FWS’s unoccupied critical-habitat designation because the
    FWS “sufficiently explained why the designation of
    unoccupied habitat . . . was essential, and conversely, why
    designation of solely occupied habitat was inadequate for the
    conservation of the species.” 
    790 F.3d at 994
    . That is, we
    recognized the function and necessity of both inquiries. See
    
    id.
     If occupied critical habitat is adequate to conserve a
    protected species, then unoccupied areas necessarily are not
    essential to conservation. But if occupied critical habitat is
    inadequate for conservation, then designation of unoccupied
    critical habitat may be essential.
    That we construed these analyses as closely related—
    particularly given the ecological facts at issue in Bear
    Valley—does not conflict with the agency’s interpretation
    that Section 424.12 requires both inquiries to be separately
    and sequentially considered. 
    Id.
     Stated another way,
    imposing a sequential analysis to determine whether
    designation of unoccupied critical habitat is proper does not
    violate Bear Valley, which acknowledged both the
    inadequacy-of-occupied-habitat       and      essentiality-of-
    unoccupied-habitat requirements and upheld the FWS’s
    challenged designation where these requirements were both
    met. Id.; cf., e.g., Lambert v. Saul, 
    980 F.3d 1266
    , 1268,
    1275–76 (9th Cir. 2020) (applying Brand X where agency’s

    (applying Brand X because adopting the agency’s
    interpretation would “conflict” with the court’s prior
    holding).
    Because we conclude that Bear Valley does not displace
    the agency’s interpretation of Section 424.12(e), we consider
    whether the FWS’s designation of Unit 3 and Subunit 4b as
    unoccupied critical habitat complies with Section 424.12, as
    interpreted by the agency. In doing so, we note that two of
    our sister circuits have likewise applied the FWS’s
    interpretation of Section 424.12, including the Tenth Circuit
    in its review of the FWS’s designations of Units 5 and 6
    under the same Final Rule at issue here. See N.M. Farm &
    Livestock Bureau, 952 F.3d at 1228–29; Markle Interests,
    L.L.C., 
    827 F.3d at 470
     (“Under the regulations in effect at

    ii.
    a.
    Turning to the merits of the FWS’s designation of Unit
    3 and Subunit 4b as unoccupied critical habitat, the FWS did
    not address whether “the designation of areas occupied by
    jaguars in 1972 would be inadequate to ensure the
    conservation of the species.” See N.M. Farm & Livestock,
    952 F.3d at 1231. Perhaps this was because the FWS made
    its unoccupied designations after hedging on its occupied
    designations 10 because it recognized that, based on the
    evidence of record, “an argument could be made that no
    areas in the United States were occupied by [jaguars] at the
    time it was listed.” Final Rule, 79 Fed. at 12582; see also id.
    at 12588 (“[S]ome expert opinions . . . suggest that jaguars
    in the United States had declined to such an extent by
    [listing] as to be effectively eliminated.”). But all we can do
    is speculate because the agency did not address Section
    424.12’s adequacy requirement other than to recite it. See id.
    at 12578; cf. Ctr. for Biological Diversity v. Haaland, 
    998 F.3d 1061
    , 1068 (9th Cir. 2021) (noting that our review is
    “limited to the reasons given by the agency for its action.”).
    It is well established that “an agency is to be held to the
    terms of its regulations.” United States v. Coleman, 
    478 F.2d 1371
    , 1374 (9th Cir. 1973) (citing Service v. Dulles, 
    354 U.S. 363
    , 372 (1957)). Because the FSW did not comply with
    Section 424.12(e) by addressing whether designated
    occupied critical habitat was adequate to address
    conservation goals, its designation of Unit 3 and Subunit 4b
    as unoccupied critical habitat was arbitrary and capricious.
    10
    The FWS designated as occupied critical habitat Units 1a, 3, 4a, 5, and
    6. Final Rule, 79 Fed. Reg. at 12591–92.
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS           33
    See N.M. Farm & Livestock Bureau, 952 F.3d at 1231
    (“Because [the FWS] did not follow its own regulations or
    provide a rational explanation for failing to do so, its
    designation of Units 5 and 6 as critical habitat was arbitrary
    and capricious.”).
    The dissent argues that we misconstrue the governing
    regulation as limiting the FWS to determining whether
    occupied critical habitat (necessarily based on occupancy at
    listing) is adequate to conserve the species before
    designating unoccupied critical habitat. Dissent at 58–59.
    Relying on the regulation’s instruction that the agency
    consider the adequacy of any “geographical area presently
    occupied by a species,” the dissent argues that the FWS may
    properly consider the adequacy of areas occupied at the time
    of designation not just the time of listing in deciding whether
    designation of unoccupied areas is essential. Dissent at 59
    (emphasis added) (quoting 
    50 C.F.R. § 424.12
    (e) (2012)).
    We do not find this argument persuasive. This reading of
    Section 424.12(e) contravenes Congress’s express
    requirement that the agency designate areas “outside the
    geographical area occupied by the species at the time it is
    listed” only where it finds “that such areas are essential for
    the conservation of the species.” See 
    16 U.S.C. § 1532
    (5)(A)(ii). We agree with the Tenth Circuit that the
    governing version of Section 424.12 “require[d] the [FWS]
    to consider a species’ range at the time of listing,” because
    any other reading “would be inconsistent with the [ESA].”
    N.M. Farm & Livestock, 952 F.3d at 1228 n.12 (quoting 
    16 U.S.C. § 1532
    (5)(A)(ii)).
    The agency’s conduct further supports our conclusion.
    The agency has not advanced or adopted the dissent’s
    interpretation. In commentary to the 2016 amendment, the
    FWS explained that the language in the 2012 version that
    34         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    “unoccupied habitat can be considered only if a
    determination is made that the [FWS] cannot recover the
    species with the inclusion of only the ‘geographical area
    presently occupied’ by the species . . . is generally
    understood to refer to habitat occupied at the time of
    listing.” Listing Endangered and Threatened Species and

    81 Fed. Reg. 7414
    , 7415 (Feb. 11, 2016) (emphasis added) (citation
    omitted). The amendment commentary further evidences
    that the agency has not and does not adopt the dissent’s
    interpretation by acknowledging that the 2012 version of the
    regulation “confusingly references present range, while the
    two parts of the statutory definition refer to the area occupied
    at the time of listing” and explaining that the amendment
    sought to “reduce confusion to change the regulations to
    track the statutory distinction.” 
    Id. at 7434
    . That is, the 2016
    amendment clarified—it did not establish—that the agency
    may consider only the “geographical area occupied by the
    species at the time of listing” in assessing whether
    designation of unoccupied areas is essential to conservation.
    
    50 C.F.R. § 424.12
    (b)(1)(i), (2019) (emphasis added); see
    also 
    id.
     § 424.12(b)(2).
    b.
    Even if the dissent were correct that the 2012 regulation
    directs the FWS to consider whether areas occupied at the
    time of designation, rather than listing, are inadequate to
    conserve the species, the FWS’s analysis still falls short
    because it did not explain why the areas that it found were
    occupied when it made its unoccupied critical habitat
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS                   35
    designations were inadequate to conserve the jaguar. 11 The
    FWS did, however, address whether designating Unit 3 and
    Subunit 4b as unoccupied critical habitat was “essential to
    the conservation of the [jaguar].” See Final Rule, 79 Fed.
    Reg. at 12582, 12594 (emphasis added). We conclude that
    none of the FWS’s justifications for finding these areas
    essential—individually or collectively—satisfy the ESA
    and, therefore, the FWS acted arbitrarily and capriciously in
    designating these areas as unoccupied critical habitat.
    The FWS determined that Unit 3 was essential because
    “(1) [this area has] demonstrated recent (since 1996)
    occupancy by jaguars; (2) [it] contain[s] features that
    comprise suitable jaguar habitat; and (3) [it] contribute[s] to
    the species’ persistence in the United States by allowing the
    normal demographic function and possible range expansion
    of the proposed Northwestern Recovery Unit, which is
    essential to the conservation of the species . . . .” See Final
    Rule, 79 Fed. Reg. at 12582. The FWS determined that
    jaguars were present because of the 1965 sighting along with
    “multiple sightings of a male jaguar from October 2012
    through September 11, 2013, in the Santa Rita Mountains.”
    Id. at 12627. Regarding suitable habitat, the FWS
    determined that Unit 3 contains favorable “[e]xpansive open
    spaces in the southwestern United States with adequate
    connectivity to Mexico that contain a sufficient native prey
    base and available surface water, have suitable vegetative
    cover and rugged topography to provide sites for resting, are
    11
    The dissent asserts that the FWS was “justified in concluding that the
    designation of other areas alone would be inadequate to ensure the
    species’ conservation,” but it does not identify where in the Final Rule
    the agency made this determination. Dissent at 60. Thus, under the
    dissent’s view, it seems the appropriate outcome would be a remand, not
    affirmance of the agency’s unoccupied critical habitat designations.

    below 2,000 m (6,582 feet (ft)) and have minimal human
    impact.” Id. at 12583. Specifically, the Santa Rita
    Mountains, where Rosemont’s Mine would be located,
    “contain all elements of the physical or biological feature
    essential to the conservation of the jaguar.” Id. at 12593.
    Finally, the FWS determined that Unit 3 is a “secondary
    area” that provides “a recovery function benefitting the
    overall recovery unit.” Id. at 12574.
    First, it cannot be disputed that the evidence of jaguars
    present within Unit 3 is thin. The 2012 and 2013 jaguar
    sightings were of a single transient male. As previously
    discussed, the FWS also relied on these sightings in
    concluding that Unit 3 was “occupied” by jaguar. Id. at
    12582. Cf. Otay Mesa Prop., L.P. v. U.S. Dep’t of Interior,
    
    344 F. Supp. 3d 355
    , 376 (D.D.C. 2018) (Jackson, J.)
    (finding that the FWS acted arbitrarily and capriciously
    when “its ‘unoccupied critical habitat’ designation relied on
    the same methodology the agency had used to determine that
    [the area designated] qualifies as occupied critical habitat”).
    And these 2012 and 2013 sightings follow a long history of
    minimal presence of the jaguar generally. The FWS reported
    in its Final Rule that “some expert opinions . . . suggest that
    jaguars in the United States had declined to such an extent
    by [listing] as to be effectively eliminated.” Final Rule, 79
    Fed. Reg. at 12588.
    Second, whether Unit 3 contains the “features that
    comprise jaguar habitat” is not determinative. Id. at 12582.
    As now-Justice Jackson has explained, “the language of the
    [ESA] does not permit reliance on the mere presence of
    pertinent biological features (PCEs) to determine that an area
    qualifies as unoccupied critical habitat” where “Congress
    has quite clearly decided that the touchstone of unoccupied
    critical habitat (in contrast to occupied critical habitat) is

    species.” Otay Mesa Prop., L.P., 344 F. Supp. 3d at 376; see
    also Ariz. Cattle Growers’ Ass’n, 606 F.3d at 1163
    (recognizing that the ESA “differentiates between
    ‘occupied’ and ‘unoccupied’ areas, imposing a more onerous
    procedure on the designation of unoccupied areas by
    requiring the Secretary to make a showing that unoccupied
    areas are essential for the conservation of the species”); see
    also Markle Interests, L.L.C. v. U.S. Fish and Wildlife Serv.,

    the denial of rehearing en banc) (“For occupied habitat, the
    relevant specific areas contain physical or biological
    features essential to the conservation of a species. For
    unoccupied habitat, the specific areas themselves must be
    essential for the species’ conservation.”).
    The dissent disputes that Unit 3 was designated as
    unoccupied critical habitat “based on the presence of PCEs
    alone,” discussing that the agency (1) also relied on 2012 and
    2013 photographs of the jaguar in Unit 3, and (2) only
    designated areas “providing at least 100 square kilometers of
    habitat.” Dissent at 56. That an area provides at least 100
    square kilometers of habitat is itself a PCE. See Final Rule,
    79 Fed. Reg. at 12587 (“[W]e determine that the primary
    constituent elements specific to jaguars are: Expansive open
    spaces in the southwestern United States of at least 100 km
    in size”). So even under the dissent’s view, the FWS’s Unit
    3 unoccupied critical habitat designation was based only on
    minimal evidence of the presence of jaguars and the
    presence of PCEs.
    This is the standard for designating occupied critical
    habitat, not unoccupied. See Otay Mesa Property, L.P., 344
    F. Supp. 3d at 374 (“[T]he designation of ‘occupied critical
    habitat’ under the ESA turns on the identification of the areas
    38         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    that the species occupies and where the PCEs exist within
    those areas.”); see also Markle Interests, L.L.C., 
    848 F.3d at 646
     (Jones, J., dissenting from the denial of rehearing en
    banc) (“The ESA’s text dictates that the unoccupied critical
    habitat designation is different and more demanding than
    occupied critical habitat designation.”). As previously
    discussed, while the FWS may consider the presence of the
    PCEs when designating unoccupied areas, it may not
    designate unoccupied critical habitat solely on that basis. See
    Otay Mesa Prop., L.P., 344 F. Supp. 3d at 376; see also Cape
    Hatteras Access Pres. All. v. U.S. Dep’t of Interior, 
    344 F. Supp. 2d 108
    , 119 (D.D.C. 2004) (“[W]ith unoccupied areas,
    it is not enough that the area’s features be essential to
    conservation, the area itself must be essential.”). The
    dissent’s approach would allow the agency to designate
    areas that are not occupied by the relevant species within the
    meaning of the ESA so long as they contain PCEs—this
    would flip the standard by making it easier for the FWS to
    designate unoccupied rather than occupied critical habitat.

    616 F.3d at 990
     (explaining
    that the standard for designating unoccupied critical habitat
    is “more demanding” than the standard for designating
    occupied critical habitat). Finally, and most important, the
    FWS has conceded there is nothing in the Final Rule
    establishing that the jaguar will be unable to recover or
    survive if Unit 3 is not designated as critical habitat. And the
    Jaguar Recovery Outline, on which the FWS relied and
    which was prepared by experts from both the United States
    and Mexico, indicates that any impact to the jaguar related
    to Unit 3 will be minimal:
    Because such a small portion of the jaguar’s
    range occurs in the U.S., it is anticipated that
    recovery of the species will rely primarily on
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS                    39
    actions that occur outside the U.S. Activities
    that may adversely or beneficially affect
    jaguars in the U.S. are less likely to affect
    recovery than activities in core areas of their
    range.
    Final Rule, 79 Fed. Reg. at 12574 (citing Jaguar
    Recovery Outline) (emphasis added). Not only that, these
    experts concluded that while “the region to the south of
    Arizona and New Mexico is especially critical for the
    recovery of the jaguar in the southwestern U.S.,” based on
    the available evidence, “any conclusions about the
    conservation importance of the habitat types in which
    jaguars have occurred or might occur in Arizona and New
    Mexico are preliminary and can vary widely.” Given this
    record, the FWS has not explained how “the best scientific
    data available” establishes that designation of Unit 3 is
    essential for conservation of the jaguar where the importance
    of this area is uncertain and this designation is “less likely”
    to impact the jaguar’s recovery. 
    16 U.S.C. § 1533
    (b)(2). 12
    Accordingly, we find that the FWS’s designation of Unit
    3 as unoccupied critical habitat was arbitrary and capricious
    because the FWS failed to provide a “reasoned evaluation of
    the relevant factors,” Marsh, 
    490 U.S. at 378
     (internal
    12
    The dissent argues that the record sufficiently establishes that Unit 3
    is essential because, as a peripheral habitat, it “provide[s] for possible
    range expansion and genetic exchange” and could “help[] the jaguar
    return to the territory it occupied before it became endangered.” Dissent
    at 54. We do not dispute that these functions would benefit the jaguar.
    But the repeated assertion that conservation is a “broad concept” that
    encompasses survival and recovery does not overcome Congress’s
    express requirement that an area itself be essential to serving these
    objectives.

    quotation marks omitted), and its designation “is without
    substantial basis in fact,” Arizona Cattle Growers’ Ass’n,
    606 F.3d at 1163.
    We find some of the same deficiencies in the FWS’s
    designation of Subunit 4b as unoccupied critical habitat. The
    FWS determined that Subunit 4b “provides connectivity
    from the Whetstone Mountains to Mexico . . . [and] is
    essential to the conservation of the jaguar because it
    contributes to the species’ persistence by providing
    connectivity to occupied areas.” Final Rule, 79 Fed. Reg. at
    12594. The FWS also noted that Subunit 4b contains “a
    combination of low human influence and either or both
    canopy cover and ruggedness such that they represent areas
    through which a jaguar may travel between the United States
    and Mexico.” Id. at 12611. Rosemount challenges this
    designation on two grounds. First, it argues that Subunit 4b
    cannot be essential because merely connecting members of
    the species in the United States and Mexico is “not essential
    to the conservation of the species.” See All. for the Wild
    Rockies v. Lyder, 
    728 F. Supp. 2d 1126
    , 1140 (D. Mont.
    2010). Second, it argues that Subunit 4c, which was also
    designated critical habitat, provides an alternate corridor
    between the United States to Mexico.
    We agree that Subunit 4b’s connectivity function and
    preferred ecological characteristics do not establish that its
    designation as critical habitat is “necessary” or
    “indispensable” for conservation of the jaguar. To be clear,
    we do not adopt Rosemont’s position that travel corridors
    linking population units are not “essential” under the
    meaning of the ESA as a general matter. Rather, we conclude
    that the FWS’s designation of Subunit 4b as an essential
    travel corridor is not supported by the record in this case—
    including that the FWS has designated a separate corridor
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS           41
    that provides the same connectivity function as Subunit 4b
    and the complete absence of evidence that jaguars have ever
    used Subunit 4b to travel between the United States and
    Mexico or for any other purpose.
    The FWS’s unexplained assertion that Subunit 4b is
    essential to jaguar persistence because it connects the
    mountains in the United States to Mexico does not make it
    so. Final Rule, 79 Fed. Reg. at 12594; see State Farm Mut.

    between the jaguar in the United States and Mexico can aid
    conservation, but that is not the ESA’s standard. See 
    16 U.S.C. § 1532
    (5)(A)(ii); see also N.M. Farm and Livestock
    Bureau, 952 F.3d at 1233 (Hartz, J., concurring) (expressing
    concern that the FWS “defined essential to mean merely
    convenient or helpful” when designating unoccupied critical
    habitat for the jaguar). The FWS must demonstrate that the
    specific travel corridor it designated—Subunit 4b—is
    essential to conservation. See Markle Interests, L.L.C., 
    848 F.3d at 638
    , 646–47 (Jones, J., dissenting from the denial of

    344 F. Supp. 2d at 119
     (noting that the unoccupied area
    “itself must be essential”). Yet, nowhere does the FWS
    42          CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    reference any information indicating what impact not
    protecting Subunit 4b would have on the jaguar. Again, this
    is particularly problematic where the experts who studied
    recovery of the jaguar concluded that any actions taken in
    the United States are “less likely to affect recovery.” Final
    Rule, 79 Fed. Reg. at 12624.
    Our decision in Alaska Oil & Gas Association v. Jewell
    does not compel a contrary result. 
    815 F.3d 544
    , 556 (9th
    Cir. 2016). There, we rejected the argument that the FWS
    could designate as critical habitat only areas containing
    actual polar bear den sites but not areas containing habitat
    suitable for denning where there was no evidence of current
    use of these areas by the species. 
    Id. at 555
    . To start, there is
    a material difference between that case and this one. There,
    we were reviewing the FWS’s designation of occupied
    critical habitat. 
    Id.
     Here, we are reviewing the FWS’s
    designation of unoccupied critical habitat. The designation
    of unoccupied critical habitat is governed by a different and
    more stringent standard. See 
    16 U.S.C. § 1532
    (5)(A); see
    also Home Builders Ass’n of N. Cal., 
    616 F.3d at 990
    ; Ariz.
    Cattle Growers’ Ass’n, 606 F.3d at 1165.
    Additionally, Alaska Oil does not displace the limitation
    that the FWS may designate as critical habitat only those
    areas shown to be “necessary to species recovery [and
    survival].” 
    815 F.3d at 556
     (emphasis added). The FWS met
    this requirement in Alaska Oil because the record there
    established “that many barrier islands provide denning
    habitat, as historically evidenced by denning polar bears”;
    that “polar bears regularly move across the barrier islands in
    search of denning, food, and rest;” and “that polar bears use
    barrier islands as migration corridors, moving between
    them.” 
    Id. at 561
    . With that evidence, we rejected that “only
    such specific areas, which the bears could be shown to utilize
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS             43
    at the present time, could be designated as [occupied] critical
    habitat,” and we upheld the FWS’s designation as critical
    habitat of “all barrier islands along the Alaska coast and their
    associated spits.” 
    Id.
     at 560–61.
    But here, the record does not support the FWS’s finding
    that Subunit 4b is essential to conservation. The Final Rule
    acknowledges that “[e]ither Subunit 4b or 4c may be used
    by the jaguar” to travel to Mexico, and that Subunit 4c is the
    more direct route. Indeed, the 2013 Biological Opinion
    seemingly concedes that designation of Subunit 4b is not
    essential, noting “it is difficult . . . to determine whether
    Subunit 4b is so important to jaguar movement that loss of
    this connectivity would lead to an adverse modification
    conclusion,” particularly given the existence of “other
    connections between Units 3 and 4 within Subunit 4c.” See
    also Final Rule, 79 Fed. Reg. at 12591 (noting that Subunit
    1b “provide[s] the jaguar connectivity with Mexico within
    the [NRU]”). This is particularly problematic where “there
    is no evidence that jaguars ever have used [Subunit 4b] for
    travel and [the FWS] cannot speculate whether they will use
    this area for travel in the future.” This is a material difference
    from the evidence of the polar bears’ presence in and use of
    the barrier islands at issue in Alaska Oil. 
    815 F.3d at 561
    .
    The FWS and the dissent nonetheless contend that
    Subunit 4b is “necessary” and “indispensable” because
    “secondary areas that provide connectivity between core
    areas . . . could allow for range expansion and genetic
    exchange,” and jaguars might use Subunit 4b to travel
    between Mexico and the United States at some point in the
    future. Dissent at 49, 56–58. Indeed, the FWS contends that
    without Subunit 4b, “50% of the connectivity to Mexico
    from the Whetstones would likely be lost.” But again, this
    necessarily is speculation, and the 2013 Biological Opinion
    44          CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    concedes that “either or both subunits [4b and 4c] may (or
    may not) be important to the conservation of jaguars in the
    NRU.” If jaguars do not use Subunit 4b to travel between
    Mexico and the United States, then it is no percentage of
    connectivity for the jaguar. Cf. N.M. Farm & Livestock
    Bureau, 952 F.3d at 1227 (finding the FWS’s critical-habitat
    designation arbitrary and capricious where it relied on
    “speculative” findings that were “not based on substantial
    evidence”). And the potential benefit of connectivity is
    immaterial if the FWS cannot establish that Subunit 4b is
    needed to achieve that benefit. See MCI Telecomm. Corp.,
    
    512 U.S. at 229
     (explaining that “an agency’s interpretation
    . . . is not entitled to deference when it goes beyond the
    meaning that the statute can bear”).
    For all these reasons, the FWS’s conclusion that it had
    “no reason not to include [Subunit 4b] as critical habitat”
    falls flat. Final Rule, 79 Fed. Reg. at 12611. See generally
    Garcia v. Holder, 
    659 F.3d 1261
    , 1267 (9th Cir. 2011)
    (granting “only limited deference” where agency decision is
    “conclusory or lacks meaningful analysis”). The dissent’s
    assertion that we are rejecting the FWS’s designation of
    Subunit 4b simply because there is no “direct evidence that
    jaguars use Subunit 4b to travel to Mexico, as opposed to
    Subunit 4c” is incorrect. Dissent at 57. Nor are we faulting
    the agency for failing to “identify . . . the precise spots where
    the species can be found.” Dissent at 57 (citing Alaska Oil,
    
    815 F.3d at
    555–57). We conclude that the agency
    designation of Subunit 4b was arbitrary and capricious based
    on the entirety of the record, including that the FWS
    designated as critical habitat a separate area that provides the
    same connectivity function as Subunit 4b (Subunit 4c) and
    failed to explain why designation of Subunit 4b was also
    essential, see Final Rule, 79 Fed. Reg. at 12611; there is no
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS           45
    evidence of jaguar using Subunit 4b at any point, for any
    purpose; and the FWS conceded that it cannot even
    “speculate whether [jaguar] will use [Subunit 4b] for travel
    in the future.” Habitat that “may (or may not) be important
    to the conservation of jaguars” definitionally is not essential
    to conservation. To conclude otherwise would render
    meaningless Congress’s limitations on the government’s
    authority to designate land as unoccupied critical habitat. See
    Alaska Oil, 
    815 F.3d at 562
    .
    In sum, the FWS has not provided a “rational connection
    between the facts found and the choice made” or
    “articulate[d] a satisfactory explanation” to justify its
    designations of Unit 3 and Subunit 4b as unoccupied critical
    habitat. State Farm Mut. Auto. Ins. Co., 
    463 U.S. at 43
    (citation omitted).
    B. Economic-Impact Analysis
    Finally, Rosemont challenges the district court’s refusal
    to remand for reconsideration of the FWS’s economic-
    impact analysis. Section 4(b)(2) of the ESA requires the
    Secretary to consider the economic impact of designating a
    particular area as critical habitat in making any such
    designation. 
    16 U.S.C. § 1533
    (b)(2). Where the Secretary
    concludes that the harms of a particular designation
    outweigh its benefits, the area may be excluded from a
    critical-habitat designation. 
    Id.
     Here, the FWS determined
    that Rosemont’s Mine “would not jeopardize the jaguar nor
    adversely modify designated critical habitat” and, therefore,
    the critical habitat designation would not cause any
    disproportionate economic impacts on Rosemont. Final
    Rule, 79 Fed. Reg. at 12626. Largely based on this
    economic-impact analysis, the FWS “did not find it to be
    reasonable or appropriate . . . to enter into the discretionary
    46         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    exclusion analysis about whether to exclude the mine from
    the final designation.” Id. at 12620.
    The district court held that the FWS applied the incorrect
    standard in determining that Rosemont’s Mine would not
    adversely modify critical habitat and remanded for the FWS
    to “reconsider” this conclusion under the proper standard of
    review. Ctr. for Biological Diversity, 441 F. Supp. 3d at 857.
    Accordingly, Rosemont claims that vacatur and remand is
    required because the predicate assumption upon which the
    Final Rule’s economic-impact analysis relied—that
    Rosemont’s Mine would not adversely modify designated
    critical habitat—was extinguished by the district court.
    Rosemont argues the agency’s economic-impact decision is
    rendered arbitrary and capricious because it rests on a
    “flawed premise [that] is fundamental to [the agency’s]
    determination.” Safe Air for Everyone v. EPA, 
    488 F.3d 1088
    , 1101 (9th Cir. 2007). The FWS and the Center contend
    that this argument is (1) waived because Rosemont did not
    raise the argument before the district court and (2)
    premature.
    We disagree that Rosemont waived this issue. We have
    discretion to address arguments that “could not have [been]
    raised” sooner and were “promptly raised . . . once the
    decision on which it was based was issued.” Randle v.
    Crawford, 
    604 F.3d 1047
    , 1056 (9th Cir. 2010); see also In
    re Eashai, 
    87 F.3d 1082
    , 1085 n.2 (9th Cir. 1996) (“[T]he
    rule of waiver is one of discretion rather than appellate
    jurisdiction.”). Here, Rosemont’s argument that the FWS
    needs to revisit its economic-impact analysis became
    relevant only after the district court concluded that the FWS
    used the wrong standard in determining that Rosemont’s
    Mine would not adversely affect the designated critical
    habitat and remanded for the FWS to reconsider that issue.
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS        47
    See Ctr. for Biological Diversity, 441 F. Supp. 3d at 857.
    Thus, it was not improper for Rosemont to raise this
    argument for the first time in its appeal of the district court’s
    decision.
    However, we agree that directing the FWS to reconsider
    its economic-impact analysis is premature at this point. We
    have concluded that the critical-habitat designations that
    Rosemont challenges must be vacated. Thus, it is unclear
    what, if any, economic-impact analysis is needed as relates
    to Rosemont’s interests. See Texas v. United States, 
    523 U.S. 296
    , 300 (1998) (“A claim is not ripe for adjudication if it
    rests upon contingent future events that may not occur as
    anticipated, or indeed may not occur at all.” (internal
    quotation marks and citations omitted)).
    III. CONCLUSION
    We affirm the district court’s vacatur of the FWS’s
    designation of the challenged area of Unit 3 as occupied
    critical habitat, and we reverse the district court’s grant of
    summary judgment to the FWS regarding its designation of
    that same area and of Subunit 4b as unoccupied critical
    habitat. As a result, we need not reach whether the FWS
    violated the APA in concluding that Rosemont’s Mine
    would not adversely modify the Unit 3 and Subunit 4b
    critical-habitat designations, which the Center argued in its
    motion for summary judgment. We remand this case with
    direction that it be returned to the agency for further
    proceedings consistent with this opinion.

    H.A. THOMAS, Circuit Judge, concurring in part and
    dissenting in part:
    I agree with the majority that the district court correctly
    vacated the Fish and Wildlife Service’s (FWS) designation
    of Unit 3 as occupied critical habitat. I also agree that it
    would be premature to vacate the FWS’s economic-impact
    analysis. But I respectfully dissent from the majority’s
    holding that the district court erred in upholding the FWS’s
    designation of Unit 3 and Subunit 4b as unoccupied critical
    habitat. When considered as a whole, the record amply
    supports the FWS’s determination that habitat within the
    United States—and the designated units in particular—are
    critical to the conservation of the jaguar as it faces threats
    elsewhere in its range.
    I.
    The jaguar is the largest felid in the Americas. It
    historically ranged from Argentina to the southern United
    States, with habitats from California to Texas. But human
    activity in the past century has driven the jaguar out of nearly
    all of its range in the United States. The decline in the
    domestic jaguar population was sufficiently severe that,
    when the FWS listed the jaguar as an endangered species in
    1972, it believed the jaguar to be extinct in the United States.
    The FWS therefore designated no critical habitat for the
    jaguar for decades after its listing.
    Things began to change for the jaguar in 1997. That year,
    recognizing that the jaguar had some presence within the
    United States, the FWS classified the jaguar as a native
    endangered species. Then, in 2009, a district court ordered
    the FWS to reconsider its decision not to designate any
    critical habitat for the jaguar. Ctr. for Biological Diversity v.
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS            49
    Kempthorne, 
    607 F. Supp. 2d 1078
    , 1094–95 (D. Ariz.
    2009). In response to that 2009 order, the FWS convened the
    Jaguar Recovery Team, a group of experts and stakeholders
    from the United States and Mexico, to gather information
    about the northernmost portion of the jaguar’s habitat.
    In 2012, the Jaguar Recovery Team issued its findings in
    the Recovery Outline for the Jaguar (Recovery Outline). The
    Recovery Team divided the area it studied into two units: the
    Northwestern Recovery Unit (NRU) and the Pan American
    Recovery Unit. The NRU stretched from Sinaloa, Mexico to
    southern Arizona and New Mexico. The Recovery Team
    divided the NRU into “core areas,” i.e., areas with reliable
    and recent evidence of jaguar habitat and reproduction, and
    “secondary areas,” i.e., areas with more sporadic evidence of
    jaguar populations and likely lower population densities.
    The portions of the NRU within the United States were
    classified as secondary.
    These secondary areas were still vital for the recovery of
    the jaguar population. As the Recovery Team explained, “the
    long-term recovery needs for the jaguar” depended not only
    on the core areas, but also upon “the maintenance of
    secondary areas that provide connectivity between core
    areas and that could allow for range expansion and genetic
    exchange.” Indeed, the Recovery Team concluded that
    “[r]ange expansion and natural movement of the jaguar may
    be of increased importance in the face of climate change and
    increased habitat fragmentation.”
    Following the Recovery Team’s report, the FWS
    designated certain areas in southern Arizona and New
    Mexico as critical habitat for the jaguar. To determine the
    jaguar’s critical habitat, the FWS identified areas that (i) are
    occupied by the jaguar, (ii) are greater than 100 square
    50         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    kilometers, and (iii) contain all of the “physical or biological
    features essential to the conservation” of the jaguar.

    79 Fed. Reg. 12572
    , 12587 (Mar. 5, 2014) (Final Rule). These areas:
    (1) Provide connectivity to Mexico; (2)
    Contain adequate levels of native prey
    species . . . (3) Include surface water sources
    available within 20 km (12.4 mi) of each

    by minimal to no human population density,
    no major roads, or no stable nighttime
    lighting.
    
    Id.
     The FWS also designated as critical habitat certain areas
    providing connectivity to the jaguar’s habitat in Mexico.
    Two areas are relevant here: Unit 3, which includes areas
    in the Santa Rita, Patagonia, Empire, and Huachuca
    Mountains; and Subunit 4b, which includes areas in the
    Whetstone Mountains connecting Unit 3 to Subunit 4a. The
    FWS found that Unit 3 contained each of the physical and
    biological features essential to jaguar conservation (also
    referred to as primary constituent elements, or PCEs), and
    that recent photographs of a jaguar in the area provided
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS                51
    evidence of jaguar occupation. 1 The FWS also designated
    Subunit 4b as unoccupied critical habitat, explaining that it
    provided connectivity between occupied areas in Unit 4 and
    Mexico.
    In making its designation, the FWS considered
    comments arguing that no areas within the United States
    should be considered critical habitat for the jaguar. The FWS
    disagreed, explaining that populations “at the edge of a
    species’ range play a role in maintaining the total genetic
    diversity of a species; in some cases, these peripheral
    populations persist the longest as fragmentation and habitat
    loss impact the total range.” 
    Id. at 12574
    . Accordingly, the
    FWS found that critical habitat within the United States
    contributed to “the jaguar’s persistence and recovery across
    the species’ entire range” and provided “areas for cyclic
    expansion and contraction” of the population in the nearby
    core areas of the NRU. 
    Id. at 12605
    . In making this
    determination, the FWS referenced the work of the Recovery
    Team, emphasizing the Recovery Team’s habitat modeling
    and its findings regarding the features essential for jaguar
    conservation.

    of any endangered species or threatened species or result in

    critical habitat may either be occupied or unoccupied by the
    species in question. Id. § 1532(5)(A). An area may be
    designated as occupied critical habitat if it contains “those
    physical or biological features (I) essential to the
    conservation of the species and (II) which may require
    special management considerations or protection.” Id.
    § 1532(5)(A)(i). To be designated as unoccupied critical
    habitat, however, the area must be “essential for the
    conservation of the species.” Id. § 1532(5)(A)(ii). In other
    words, the designation of occupied critical habitat focuses
    on the features found in the area, while the designation of
    unoccupied critical habitat requires that the habitat itself be
    essential to the species’ conservation. See id. § 1532(5)(A).
    Under the Administrative Procedure Act, the FWS’s

    The majority discusses at length the meaning of the word
    “essential” in the ESA’s definition of critical habitat,
    explaining that the term is used as a synonym for
    “necessary” or “indispensable.” But this discussion does
    little to resolve the dispute in this case. The parties do not
    disagree on the definition of the term “essential.” And the
    ESA does not require that critical habitat be “essential” in
    the abstract. Rather, it requires that critical habitat be
    “essential for the conservation of the species.” 
    16 U.S.C. § 1532
    (5)(A)(ii).
    Conservation is a broad concept, including “all methods
    that can be employed to ‘bring any endangered species or

    provided pursuant to [the ESA] are no longer necessary.’”

    The FWS found that the jaguar’s recovery would “rely
    primarily on actions that occur outside the U.S.” Final Rule,
    79 Fed. Reg. at 12574. It further found that “[a]ctivities that
    may . . . affect jaguars in the U.S. are less likely to affect
    recovery than activities in core areas of their range.” Id.
    Contrary to the conclusion reached by the majority, there is
    no conflict between these findings and a designation of
    critical habitat within the United States. Whenever the
    United States contains only a minority of a species’ critical
    habitat, it is likely that conservation efforts in other countries
    will be more important than those here. We have previously
    rejected the notion that “designation is only necessary where
    it would protect the majority of species habitat.” See Nat.
    Res. Def. Council v. U.S. Dep’t of the Interior, 
    113 F.3d 1121
    , 1126 (9th Cir. 1997). The ESA, moreover, defines
    conservation broadly, and certain habitat may be “essential
    for the conservation of the species” even if other habitat is
    more important. 
    16 U.S.C. § 1532
    (5)(A)(ii).
    Here, the FWS adequately justified its determination that
    habitat within the United States is essential to the jaguar’s
    conservation, even though the jaguar’s core habitat is found
    elsewhere. As the FWS explained, threats to the jaguar at the
    core of its range increase the value of habitat at the
    periphery. These peripheral habitats not only provide for
    possible range expansion and genetic exchange but also have
    the potential to outlast core areas as threats to the species
    increase. The jaguar’s range in 1972, when it was listed as
    an endangered species, was already much smaller than its
    historical range, which extended well into the United States.
    The designation of habitat within the United States therefore
    helps the jaguar return to territory it occupied before it
    became endangered. Indeed, “[s]ince the point of the ESA is
    to ensure the species’ recovery, it makes little sense to limit

    B.
    Having determined that habitat within the United States
    is essential to the jaguar’s conservation, the FWS reasonably
    designated Unit 3 and Subunit 4b as critical habitat.
    i.
    The majority contends that the designation of Unit 3 was
    improper because the presence of PCEs alone cannot be
    determinative in designating an area as unoccupied critical
    habitat. But the FWS properly applied the appropriate
    standard: that the designated habitat be “essential to the
    conservation of the species.” 
    16 U.S.C. § 1532
    (5)(a)(ii).
    The FWS designated Unit 3 as critical habitat because it
    contained evidence of recent jaguar habitation, featured
    every one of the PCEs identified by the Recovery Team to
    be essential to the jaguar’s recovery, and provided for the
    species’ persistence in the United States and possible
    expansion to a new range. This designation was based on the
    Recovery Team’s findings, which employed scientific
    modeling to determine which habitat features were essential
    to the jaguar. It was justified also by the Recovery Team’s
    determination that areas at the edge of the jaguar’s range
    play an important role in supporting the jaguar’s recovery
    and survival—particularly toward the northwest of the
    species’ range, where opportunities for expansion are
    necessary to preserve the genetic health of the NRU’s jaguar
    population.
    The FWS determined that Unit 3 did not contain just
    some but rather all PCEs “essential to the conservation” of
    56           CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    the jaguar. Final Rule, 79 Fed. Reg. at 12587. This
    determination exceeds the standard necessary for
    designation of occupied critical habitat. See Home Builders
    Ass’n of N. Cal., 
    616 F.3d at
    988–89. Nothing in the ESA
    prevents the FWS from designating unoccupied habitat on
    the basis that the presence of certain PCEs makes the habitat
    “essential for the conservation of the species.” See 
    16 U.S.C. § 1532
    (5)(A)(ii). We have, in fact, upheld such designations
    in the past. See Bear Valley Mut. Water Co., 
    790 F.3d at 994
    .
    Nor was the designation of Unit 3 based on the presence
    of PCEs alone. Because the jaguar is a territorial animal
    requiring an expansive range, the FWS designated only areas
    providing at least 100 square kilometers of habitat. The FWS
    also pointed to multiple undisputed records of jaguars within
    the designated habitat, including photographs in 2012 and
    2013 of a male jaguar in Unit 3. 2 Taken together, these
    explanations satisfy the FWS’s obligation to “articulate[] a
    rational connection between the facts found and the
    conclusions made.” 
    Id. at 986
     (internal quotation mark
    omitted).
    ii.
    The FWS also properly designated Subunit 4b as
    unoccupied critical habitat. As the FWS explained, Subunit
    4b provides connectivity between Unit 4 and the jaguar’s
    habitat in Mexico, and includes features conducive to the
    jaguar’s travel, such as canopy cover, ruggedness, and low
    human influence. The agency’s determination was supported
    by the Recovery Outline, in which the Recovery Team
    2
    Even if these photographs were too recent to show that Unit 3 was
    occupied at the time of listing in 1972, the FWS was not precluded from
    considering them to determine that the area was essential to the
    conservation of the jaguar at the time of designation in 2014.
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS          57
    explained that connectivity between jaguar populations was
    critical to the species’ genetic health and to its ability to
    expand toward the edge of its range. It was also supported
    by a 2013 draft biological opinion regarding the Rosemont
    Copper Mine, which found that disruptions to the
    connectivity provided by Subunit 4b would reduce the
    conservation value of the designated habitat as a whole.
    The majority finds the designation of Subunit 4b
    arbitrary and capricious because the FWS did not provide
    direct evidence that jaguars use Subunit 4b to travel to
    Mexico, as opposed to Subunit 4c (another unoccupied
    subunit connecting Subunit 4a to Mexico through Unit 3).
    But contrary to the majority’s suggestion, this designation
    was not merely speculative. The FWS recognized that, to
    reach the jaguar population in Subunit 4a, jaguars would
    need the ability to travel through at least one of Subunit 4b
    and Subunit 4c—if not both. And the FWS determined that
    Subunit 4b contained features conducive to this purpose.
    These findings are sufficient to satisfy the FWS’s
    burden. As we explained in Alaska Oil, an area may be
    designated even as occupied critical habitat without direct
    evidence of a species’ presence. 
    815 F.3d at
    555–56. Nor is
    the FWS required to identify the specific location of the
    features justifying its designation or the precise spots where
    the species can be found. 
    Id.
     at 555–57. The FWS need only
    “dr[a]w rational conclusions from the best available
    scientific data.” 
    Id. at 562
    . The FWS has satisfied that
    standard here.
    The majority attempts to distinguish Alaska Oil because
    it involved a designation of occupied rather than unoccupied
    critical habitat. But that fact simply explains why our
    decision in Alaska Oil focused on the locations of PCEs, the
    58         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    presence of which is required for a designation of occupied
    critical habitat. See 
    id. at 556
    ; 
    16 U.S.C. § 1532
    (5)(A)(i). It
    does not, however, distinguish Alaska Oil’s holding that the
    FWS need not identify the specific locations of species or
    features when designating critical habitat. That holding is
    derived from the rule that the ESA “requires use of the best
    available technology, not perfection”—a rule applicable to
    both designations of occupied and unoccupied critical
    habitat. 
    Id. at 555
    ; 
    16 U.S.C. § 1533
    (b)(2).
    The majority’s approach risks prohibiting any
    designation of connective critical habitat in the absence of
    direct evidence that a species traverses through a specific
    designated route. Unless the FWS were certain which
    specific route or routes a species takes between areas of its
    habitat, the majority’s approach would preclude the FWS
    from protecting any connective habitat at all. The ESA does
    not require this level of granularity. See Alaska Oil, 
    815 F.3d at
    557–58 (upholding a critical habitat designation specified
    in five-mile increments). Here, the FWS reasonably
    determined that the jaguar would require connectivity
    between its core population in Mexico and its critical habitat
    in the United States, and that Subunit 4b was well-suited for
    this purpose.
    C.
    Finally, the majority finds that the FWS violated its own
    regulation, because it designated unoccupied habitat without
    first determining that designation of only occupied habitat
    would be inadequate to ensure the conservation of the jaguar.
    As an initial matter, the majority misconstrues the applicable
    regulation. The majority faults the FWS for failing to
    consider whether it would have been enough to designate
    only habitat occupied by the jaguar “in 1972.” Majority Op.
    CTR. FOR BIOLOGICAL DIVERSITY V. USFWS                     59
    at 32. At the time the designation was issued, however, the
    FWS’s regulation required the agency to determine whether
    the “geographical area presently occupied by a species . . .
    would be inadequate to ensure the conservation of the
    species” before designating unoccupied critical habitat. 
    50 C.F.R. § 424.12
    (e) (2012). In other words, the regulation
    directed the agency to consider the species’ present range,
    rather than its range at the time of listing. 3
    This distinction matters. Even if the evidence on the
    record was insufficient to support a finding that the jaguar
    occupied Unit 3 in 1972, the FWS was justified in
    determining that Unit 3 comprised part of the jaguar’s
    present range due to recent uncontroverted evidence of
    jaguar habitation, as well as the presence of every PCE. See
    Final Rule, 79 Fed. Reg. at 12578–79; cf. Alaska Oil, 
    815 F.3d at
    556–57 (upholding a designation of occupied critical
    habitat due to the presence of PCEs, even without
    geographically precise evidence of the species’ presence in
    the habitat). Accordingly, the FWS’s regulation did not
    require it to make a separate finding that the designation of
    occupied areas other than Unit 3 would have been sufficient
    to ensure the jaguar’s conservation.
    In any event, the FWS adequately explained why
    designating critical habitat within the United States was
    essential to the conservation of the jaguar—and why leaving
    3
    The majority points to a statement from the FWS’s rule repealing this
    provision in 2016 which asserts that the reference to “‘geographical area
    presently occupied’ by the species . . . is generally understood to refer to
    habitat occupied at the time of listing.” Listing Endangered and
    Threatened Species and Designating Critical Habitat; Implementing
    Changes to the Regulations for Designating Critical Habitat, 
    81 Fed. Reg. 7414
    , 7415 (Feb. 11, 2016). But this interpretation of the regulation
    is contrary to its plain language. See 
    50 C.F.R. § 424.12
    (e) (2012).
    60         CTR. FOR BIOLOGICAL DIVERSITY V. USFWS
    conservation efforts entirely to other countries
    encompassing the core of the jaguar’s range would not be
    enough. Because humans have killed jaguars or damaged
    their habitat, the jaguar’s range has diminished significantly
    over the last century. As the Recovery Team found, the
    jaguar continues to face threats to its survival in much of its
    range. Accordingly, areas at the periphery of the jaguar’s
    range play an important role in ensuring that the jaguar can
    not only survive but also recover.
    For the reasons discussed above, these determinations
    justified the designation of critical habitat in Unit 3 and
    Subunit 4b. Unit 3 not only provides every one of the PCEs
    essential to the jaguar but also contains recent evidence of
    jaguar habitation. And Subunit 4b provides critical
    connectivity to Mexico, without which the jaguar may not
    be able to move between periphery and core populations.
    The FWS was therefore justified in concluding that the
    designation of other areas alone would be inadequate to
    ensure the species’ conservation. See Final Rule, 79 Fed.
    Reg. at 12590.
    *       *       *
    The FWS reasonably determined that habitat within the
    United States was critical for the jaguar’s conservation and
    recovery. This determination was supported by factual
    assessments lying at the core of the agency’s expertise.
    Accordingly, I would uphold the FWS’s designation of
    critical habitat for the jaguar.
