    Appeals from the United States District Court
    for the Eastern District of Louisiana
    Before REAVLEY, OWEN, and HIGGINSON, Circuit Judges.
    STEPHEN A. HIGGINSON, Circuit Judge:
    This appeal requires us to consider the United States Fish and Wildlife
    Service’s inclusion of private land in a critical-habitat designation under the
    Endangered Species Act. Misconceptions exist about how critical-habitat
    designations impact private property. Critical-habitat designations do not
    transform private land into wildlife refuges. A designation does not authorize
    the government or the public to access private lands. Following designation,
    the Fish and Wildlife Service cannot force private landowners to introduce
    endangered species onto their land or to make modifications to their land. In
    short, a critical-habitat designation alone does not require private landowners
    to participate in the conservation of an endangered species. In a thorough
    opinion, District Judge Martin L. C. Feldman held that the Fish and Wildlife
    Service properly applied the Endangered Species Act to private land in St.
    Tammany Parish, Louisiana. As we discuss below, we AFFIRM Judge
    Feldman’s judgment upholding this critical-habitat designation.
    FACTS AND PROCEEDINGS
    This case is about a frog—the Rana sevosa—commonly known as the
    dusky gopher frog. 1 These frogs spend most of their lives underground in open-
    1 See Designation of Critical Habitat for Mississippi Gopher Frog, 76 Fed. Reg. 59,774,
    59,775 (proposed Sept. 27, 2011) (to be codified at 50 C.F.R. pt. 17) [hereinafter Revised
    Proposal]. The frog was previously known as the Mississippi gopher frog, but further
    taxonomic research indicated that the dusky gopher frog is different from other gopher frogs,
    warranting acceptance as its own species: the Rana sevosa or the dusky gopher frog. 
    Id. We will
    refer to the frog as the dusky gopher frog.

    canopied pine forests. 2 They migrate to isolated, ephemeral ponds to breed.
    Final Designation, 77 Fed. Reg. at 35,129. Ephemeral ponds are only
    seasonally flooded, leaving them to dry out cyclically and making it impossible
    for predatory fish to survive. See 
    id. at 35,129,
    35,131. After the frogs are
    finished breeding, they return to their underground habitats, followed by their
    offspring. 
    Id. at 35,129.
    When the dusky gopher frog was listed as an
    endangered species, there were only about 100 adult frogs known to exist in
    the wild. 3 Although, historically, the frog was found in parts of Louisiana,
    Mississippi, and Alabama, today, the frog exists only in Mississippi. Final
    Rule, 66 Fed. Reg. at 62,993–94; Final Designation, 77 Fed. Reg. at 35,132. The
    primary threat to the frog is habitat degradation. Final Rule, 66 Fed. Reg. at
    62,994.
    In 2010, under the Endangered Species Act (“ESA”), 16 U.S.C. §§ 1531–
    1544, the United States Fish and Wildlife Service (“the Service”) 4 published a
    proposed rule to designate 1,957 acres in Mississippi as “critical habitat” for
    the dusky gopher frog. 5 In response to concerns raised during the peer-review
    2  Designation of Critical Habitat for Dusky Gopher Frog (Previously Mississippi
    Gopher Frog), 77 Fed. Reg. 35,118, 35,129 (June 12, 2012) (to be codified at 50 C.F.R. pt. 17)
    [hereinafter Final Designation]. It appears that the frogs are not accustomed to human
    interaction. If you pick up a gopher frog and hold it, the frog will play dead and even cover
    its eyes; if you hold the frog long enough, it will peak at you and then pretend to be dead
    again.

    Dusky Gopher Frog as Endangered, 66 Fed. Reg. 62,993, 62,993, 62,995, 63,000 (Dec. 4, 2001)
    (to be codified at 50 C.F.R. pt. 17) [hereinafter Final Rule].
    4 The Secretary of the Department of the Interior and the Secretary of the Department
    of Commerce are jointly charged with administering the ESA. See 16 U.S.C. § 1532(15). The
    Secretary of the Interior administers the ESA through the Fish and Wildlife Service. We refer
    to both the Secretary and the agency as the “Service.”

    process about the sufficiency of this original proposal, the Service’s final
    designation of critical habitat expanded the area to 6,477 acres in four counties
    in Mississippi and one parish in Louisiana. See Revised Proposal, 76 Fed. Reg.
    at 59,776; Final Designation, 77 Fed. Reg. at 35,118–19. The designated area
    in Louisiana (“Unit 1”) consists of 1,544 acres in St. Tammany Parish. Final
    Designation, 77 Fed. Reg. at 35,118. Although the dusky gopher frog has not
    occupied Unit 1 for decades, the land contains historic breeding sites and five
    closely clustered ephemeral ponds. See Revised Proposal, 76 Fed. Reg. at
    59,783; Final Designation, 77 Fed. Reg. at 35,123–24, 35,133, 35,135. The final
    critical-habitat designation was the culmination of two proposed rules,
    economic analysis, two rounds of notice and comment, a scientific peer-review
    process including responses from six experts, and a public hearing. See Final
    Designation, 77 Fed. Reg. at 35,119.
    Together, Plaintiffs–Appellants Markle Interests, L.L.C., P&F Lumber
    Company 2000, L.L.C., PF Monroe Properties, L.L.C., and Weyerhaeuser
    Company (collectively, “the Landowners”) own all of Unit 1. Weyerhaeuser
    Company holds a long-term timber lease on all of the land that does not expire
    until 2043. The Landowners intend to use the land for residential and
    commercial development and timber operations. Through consolidated suits,
    all of the Landowners filed actions for declaratory judgment and injunctive
    relief against the Service, its director, the Department of the Interior, and the
    Secretary of the Interior. The Landowners challenged only the Service’s
    designation of Unit 1 as critical habitat, not the designation of land in
    Mississippi.
    The district court allowed the Center for Biological Diversity and the
    Gulf Restoration Network (collectively, “the Intervenors”) to intervene as
    defendants in support of the Service’s final designation. All parties filed cross-

    summary judgment in favor of the Service on the merits. See Markle Interests,

    1992) (noting that the court of appeals reviews the administrative record de
    novo when the district court reviewed an agency’s decision by way of a motion
    for summary judgment). Our review of the Service’s administration of the ESA
    is governed by the Administrative Procedure Act (“APA”). See Bennett v. Spear,
    
    520 U.S. 154
    , 171–75 (1997) (holding that a claim challenging the Service’s
    alleged “maladministration of the ESA” is not reviewable under the citizen-
    suit provisions of the ESA, but is reviewable under the APA); see also 5 U.S.C.
    §§ 702, 704. When reviewing agency action under the APA, this court must “set
    aside agency action, findings, and conclusions found to be—(A) arbitrary,
    capricious, an abuse of discretion, or otherwise not in accordance with
    law; (B) contrary to constitutional right, power, privilege, or immunity; [or]
    (C) in excess of statutory jurisdiction, authority, or limitations.” 5 U.S.C.
    § 706(2).

    Under the arbitrary-and-capricious standard,
    we will not vacate an agency’s decision unless it has relied on
    factors which Congress had not intended it to consider, entirely
    failed to consider an important aspect of the problem, offered an

    DISCUSSION
    The Landowners raise three challenges to the Service’s designation of
    Unit 1 as critical habitat for the dusky gopher frog. They argue that the
    designation (1) violates the ESA and the APA, (2) exceeds the Service’s
    constitutional authority under the Commerce Clause, U.S. Const. art. I, § 8, cl.
    3, and (3) violates the National Environmental Policy Act (“NEPA”), 42 U.S.C.
    § 4321 et seq. As we discuss below, each of their arguments fails.
    I.    Endangered Species Act
    Congress enacted the ESA “to provide a means whereby the ecosystems
    upon which endangered species . . . depend may be conserved” and “to provide
    6
    Case: 14-31008       Document: 00513573768          Page: 7     Date Filed: 06/30/2016
    No. 14-31008
    Cons w/ No. 14-31021
    a program for the conservation of such endangered species.” 16 U.S.C.
    § 1531(b). The ESA broadly defines “conservation.” It includes “the use of all
    methods and procedures which are necessary to bring any endangered
    species . . . to the point at which the measures provided [by the ESA] are no
    longer necessary.” 
    Id. § 1532(3).
    In other words, “the objective of the ESA is to
    enable [endangered] species not merely to survive, but to recover from their
    endangered or threatened status.” Sierra Club v. U.S. Fish & Wildlife Serv.,
    
    245 F.3d 434
    , 438 (5th Cir. 2001); see also Tenn. Valley Auth. v. Hill, 
    437 U.S. 153
    , 184 (1978) (“The plain intent of Congress in enacting this statute was to
    halt and reverse the trend toward species extinction, whatever the cost. This
    is reflected not only in the stated policies of the Act, but in literally every
    section of the statute.”).
    To achieve this objective, the ESA requires the Service to first identify
    and list endangered and threatened species. See 16 U.S.C. § 1533(a)(1). Listing
    a species as endangered or threatened then triggers the Service’s statutory
    duty to designate critical habitat “to the maximum extent prudent and
    determinable.” See 
    id. § 1533(a)(3)(A)(i).
    6 “Critical habitat designation
    primarily benefits listed species through the ESA’s [Section 7] consultation
    mechanism.” Sierra 
    Club, 245 F.3d at 439
    ; see 16 U.S.C. § 1536 (describing the
    6  The Service typically is required to designate critical habitat at the same time that
    it lists a species as endangered or threatened. 16 U.S.C. § 1533(a)(3)(A)(i). But if critical
    habitat is not “determinable” at the time of listing, the Service can extend the deadline for
    making a critical-habitat designation. See 
    id. § 1533(b)(6)(A)(ii),
    (b)(6)(C)(ii). Although the
    Service listed the dusky gopher frog as endangered in 2001, it declined to designate critical
    habitat at that time because of budget limitations. See Final Rule, 66 Fed. Reg. at 63,000. Six
    years later, in 2007, the Service still had not designated critical habitat for the frog. The
    Center for Biological Diversity therefore sued the Service for failing to timely designate
    critical habitat. That lawsuit resulted in a court-approved settlement agreement that set
    deadlines for the Service to designate critical habitat for the dusky gopher frog. The Service’s
    resulting designations under this agreement, including the designation of Unit 1, prompted
    the lawsuit that we are considering on appeal.

    Section 7 consultation process). Under this section, once habitat is designated
    as critical, federal agencies are prohibited from authorizing, funding, or
    carrying out any action that is likely to result in “the destruction or adverse
    modification” of that critical habitat without receiving a special exemption. 7 16
    U.S.C. § 1536(a)(2). To satisfy the requirements of Section 7, federal agencies
    must consult with the Service before taking any action that might negatively
    affect critical habitat. 8 Only federal agencies—not private parties—must
    engage in this Section 7 consultation process. See id.; 50 C.F.R. § 402.14(a).
    Thus, as Judge Feldman explained, “absent a federal nexus, [the Service]
    cannot compel a private landowner to make changes to restore his designated
    property into optimal habitat.” Markle 
    Interests, 40 F. Supp. 3d at 750
    .
    A. Standing
    Before addressing the merits of the Service’s critical-habitat designation,
    we first address whether the Landowners have standing to challenge the
    designation. “The question of standing involves both constitutional limitations
    on federal-court jurisdiction and prudential limitations on its exercise.”
    
    Bennett, 520 U.S. at 162
    (internal quotation marks omitted). In particular, to
    establish standing under the APA, in addition to Article III standing, a plaintiff
    must show that “the interest sought to be protected by the [plaintiff] is
    arguably within the zone of interests to be protected or regulated by the statute
    or constitutional guarantee in question.” 
    Id. at 175
    (quoting Ass’n of Data
    7 Section 7 consultation is also required whenever any federal action will “jeopardize
    the continued existence” of an endangered species, regardless of whether the Service has
    designated critical habitat. 16 U.S.C. § 1536(a)(2); see Sierra 
    Club, 245 F.3d at 439
    .
    8 If the Service determines that a contemplated action—the issuance of a permit, for
    example—is likely to adversely modify critical habitat, the Service must suggest “reasonable
    and prudent alternatives” that the consulting agency could take to avoid adverse
    modification. See 50 C.F.R. § 402.14(h)(3). These alternatives must be “economically and
    technologically feasible.” 
    Id. § 402.02.
                                                 8

    Processing Serv. Orgs., Inc. v. Camp, 
    397 U.S. 150
    , 153 (1970)). Although the
    district court correctly held that the APA provided the proper vehicle for the
    Landowners to challenge the Service’s administration of the ESA, the district
    court did not address the APA’s zone-of-interests test; instead, it held only that
    the Landowners have standing under Article III. On appeal, the Service did
    not brief the zone-of-interests issue or challenge the district court’s conclusion
    that the Landowners have Article III standing.
    Even though the Service did not appeal the district court’s standing
    conclusion, we must independently assess the Landowners’ Article III
    standing. 9 See Hang On, Inc. v. City of Arlington, 
    65 F.3d 1248
    , 1251 (5th Cir.
    1995) (“The federal courts are under an independent obligation to examine
    their own jurisdiction, and standing is perhaps the most important of the
    jurisdictional doctrines.” (alterations and internal quotation marks omitted)).
    “Article III of the Constitution limits federal courts’ jurisdiction to certain
    ‘Cases’ and ‘Controversies.’” Clapper v. Amnesty Int’l USA, 
    133 S. Ct. 1138
    ,
    1147 (2013). “To satisfy the ‘case’ or ‘controversy’ requirement of Article III,
    which is the ‘irreducible constitutional minimum’ of standing, a plaintiff
    must . . . demonstrate that he has suffered ‘injury in fact,’ that the injury is
    ‘fairly traceable’ to the actions of the defendant, and that the injury will likely
    be redressed by a favorable decision.” 
    Bennett, 520 U.S. at 162
    (quoting Lujan
    v. Defenders of Wildlife, 
    504 U.S. 555
    , 560–61 (1992)). The injury must be
    concrete and particularized, as well as actual or imminent.

    beyond its purpose, which is to ensure that the alleged injury is not too
    speculative for Article III purposes—that the injury is certainly impending.”).
    “The party invoking federal jurisdiction bears the burden of establishing these
    elements.” 
    Lujan, 504 U.S. at 561
    .
    Here, the Landowners assert two alleged injuries: lost future
    development and lost property value. The first—loss of future development—
    is too speculative to support Article III standing. Although “[a]n increased
    regulatory burden typically satisfies the injury in fact requirement,” Contender
    Farms, L.L.P. v. U.S. Dep’t of Agric., 
    779 F.3d 258
    , 266 (5th Cir. 2015), any
    regulatory burden on Unit 1 is purely speculative at this point. As the Service
    emphasized in the designation, if future development occurring on Unit 1
    avoids impacting jurisdictional wetlands, no federal permit would be required
    and the ESA’s Section 7 consultation process would not be triggered. See Final
    Designation, 77 Fed. Reg. at 35,126 (noting that the range of possible economic
    impact to Unit 1 of $0 to $33.9 million “reflects uncertainty regarding future
    land use”); 
    id. at 35,140
    (observing that “considerable uncertainty exists
    regarding the likelihood of a Federal nexus for development activities [in Unit
    1]”); see also 16 U.S.C. § 1536(a)(2); 50 C.F.R. § 402.14(a). Judge Feldman
    similarly stressed this point, explaining that, “if a private party’s action has no
    federal nexus (if it is not authorized, funded, or carried out by a federal agency),
    no affirmative obligations are triggered by the critical habitat designation.”
    Markle 
    Interests, 40 F. Supp. 3d at 750
    .
    Because the Landowners have not provided evidence that specific
    development projects are likely to be impacted by Section 7 consultation, 10 lost
    10  To the contrary, the record reflects that, at the time Unit 1 was designated,
    development plans had already been delayed because of the recession and the mortgage

    identified specific, ongoing development projects that would be delayed

    The Landowners’ assertion of lost property value, by contrast, is a
    concrete and particularized injury that supports standing. See Sabine River
    
    Auth., 951 F.2d at 674
    (recognizing that injury in fact includes economic
    injury). The Landowners assert that their land has already lost value as a
    result of the critical-habitat designation. Indeed, as the Service recognized in
    its Final Economic Analysis, given the “stigma” attached to critical-habitat
    designations, “[p]ublic attitudes about the limits or restrictions that critical
    injury, but also highlights that any injury, however speculative, is not fairly traceable to the
    critical-habitat designation. Moreover, the long-term timber lease running on the land until
    2043 also suggests that development may not occur on Unit 1 in the foreseeable future.
    Although the Landowners suggest that they could renegotiate the timber lease as conditions
    change, they have not demonstrated that they have concrete plans to do so.

    habitat may impose can cause real economic effects to property owners,
    regardless of whether such limits are actually imposed.” As a result, “a
    property that is designated as critical habitat may have a lower market value
    than an identical property that is not within the boundaries of critical habitat
    due to perceived limitations or restrictions.” The Service further assumed that
    “any reduction in land value due to the designation of critical habitat will
    happen immediately at the time of the designation.”
    Causation and redressability flow naturally from this injury. If a
    plaintiff—or, here, the plaintiffs’ land—is the object of government action,
    “there is ordinarily little question that the action . . . has caused him injury,
    and that a judgment preventing . . . the action will redress it.” 
    Lujan, 504 U.S. at 561
    –62. We conclude that the Landowners’ decreased property value is fairly
    traceable to the Service’s critical-habitat designation and that this injury
    would likely be redressed by a favorable decision. Thus, the Landowners have
    established Article III standing based on lost property value.
    The question nevertheless remains whether the Landowners satisfy the
    APA’s zone-of-interests requirement. See 
    Bennett, 520 U.S. at 175
    –77. The
    Service, however, has not argued—either in the district court or this court—
    that the Landowners’ interests fall outside the zone of interests that the ESA
    is designed to protect. “Unlike constitutional standing, prudential standing
    arguments may be waived.” Bd. of Miss. Levee Comm’rs v. EPA, 
    674 F.3d 409

    11 We are mindful that the Supreme Court has recently clarified that “‘prudential

    Solid Waste Mgmt. Auth., 
    389 F.3d 491
    , 498 (5th Cir. 2004), we decline to do
    so here. Because the Service failed to raise this argument, we hold that the
    Service has forfeited a challenge to the Landowners’ standing under the zone-
    of-interests test. We thus conclude that the Landowners have standing to
    challenge the Service’s critical-habitat designation.
    B. Critical-Habitat Designation
    The ESA expressly envisions two types of critical habitat: areas occupied
    by the endangered species at the time it is listed as endangered and areas not
    occupied by the species at the time of listing. See 16 U.S.C. § 1532(5)(A)(i)–(ii).
    To designate an occupied area as critical habitat, the Service must
    demonstrate that the area contains “those physical or biological features . . .
    essential to the conservation of the species.” 12 
    Id. § 1532(5)(A)(i).
    To designate
    unoccupied areas, the Service must determine that the designated areas are
    “essential for the conservation of the species.” 
    Id. § 1532(5)(A)(ii).
    As Judge
    Feldman noted below, “Congress did not define ‘essential’ but, rather,
    delegated to the Secretary the authority to make that determination.” Markle
    
    Interests, 40 F. Supp. 3d at 760
    . Thus, when the Service promulgates, in a
    formal rule, a determination that an unoccupied area is “essential for the
    conservation” of an endangered species, Chevron deference is appropriate. See
    
    id. (citing Chevron,
    U.S.A., Inc. v. Natural Res. Def. Council, Inc., 
    467 U.S. 837
    ,
    843 n.9 (1984)); Knapp v. U.S. Dep’t of Agric., 
    796 F.3d 445
    , 454 (5th Cir. 2015)
    12Under the regulations in place at the time of the critical-habitat designation at issue
    here, the Service referred to these “physical or biological features” as “primary constituent
    elements” or “PCEs.” 50 C.F.R. § 424.12(b) (2012). The primary constituent elements that
    make up the dusky gopher frog’s habitat are (1) ephemeral ponds used for breeding,
    (2) upland, open-canopy forests “adjacent to and accessible to and from breeding ponds,” and
    (3) upland connectivity habitat to allow the frog to move between breeding and nonbreeding
    habitats. Final Designation, 77 Fed. Reg. at 35,131.

    (“[A]dministrative implementation of a particular statutory provision qualifies
    for Chevron deference when it appears [(1)] that Congress delegated authority
    to the agency generally to make rules carrying the force of law, and [(2)] that
    the agency interpretation claiming deference was promulgated in the exercise
    of that authority.” (alterations in original)).
    The Service must designate critical habitat “on the basis of the best
    scientific data available and after taking into consideration the economic
    impact, the impact on national security, and any other relevant impact, of
    specifying any particular area as critical habitat.” 
    Id. § 1533(b)(2).
    “When
    examining this kind of scientific determination, as opposed to simple findings
    of fact, a reviewing court must generally be at its most deferential.” Balt. Gas

    , 699 (5th Cir.
    2010) (“Where an agency’s particular technical expertise is involved, we are at
    our most deferential in reviewing the agency’s findings.”).
    In addition, under the regulations in place at the time of the critical-
    habitat designation at issue here, before the Service could designate
    unoccupied land as critical habitat, it first had to make a finding that “a
    designation limited to [a species’] present range would be inadequate to ensure
    the conservation of the species.” 50 C.F.R. § 424.12(e) (2012) (emphasis added).
    Unit 1 is unoccupied. Thus, under its own regulations, the Service first had to
    make an inadequacy determination. The Service’s first proposed designation
    included only land in Mississippi and did not include Unit 1. See Original
    Proposal, 75 Fed. Reg. at 31,395–99 (identifying eleven units in Mississippi).
    During the peer-review and comment process on this original proposal, the
    expert reviewers expressed that the designated habitat in the proposal was
    inadequate to ensure the conservation of the frog. The experts therefore urged
    14
    Case: 14-31008        Document: 00513573768           Page: 15     Date Filed: 06/30/2016

    the Service to expand the designation to Louisiana or Alabama, the two other
    states in the frog’s historical range. See Revised Proposal, 76 Fed. Reg. at
    59,776; Final Designation, 77 Fed. Reg. at 35,119, 35,121, 35,123–24.
    The Service adopted this consensus expert conclusion, finding that
    designating the occupied land in Mississippi was “not sufficient to conserve the
    species.” Final Designation, 77 Fed. Reg. at 35,123. The Service explained that
    “[r]ecovery of the dusky gopher frog will not be possible without the
    establishment of additional breeding populations of the species,” and it
    emphasized that it was necessary to designate critical habitat outside of
    Mississippi to protect against potential local events, such as drought and other
    environmental disasters. 
    Id. at 35,124–25.
    The Service therefore determined
    that “[a]dditional areas that were not known to be occupied at the time of
    listing are essential for the conservation of the species.” 
    Id. at 35,123.
    In sum,
    all of the experts agreed that designating occupied land alone would not be
    sufficient to conserve the dusky gopher frog. Thus, the Service’s prerequisite
    inadequacy finding—a finding that the Landowners did not challenge 13—was
    not arbitrary and capricious.
    Having satisfied this preliminary requirement, the Service was next
    required to limit the critical-habitat designation to unoccupied areas that are
    “essential for the conservation of the species.” 16 U.S.C. § 1532(5)(A)(ii). The
    13 Amici supporting the Landowners do challenge this finding, and the Landowners
    asserted at oral argument that they would contest this finding. The Landowners, however,
    did not challenge this finding in either of their briefs on appeal. We therefore will not consider
    it. See World Wide St. Preachers Fellowship v. Town of Columbia, 
    591 F.3d 747
    , 752 n.3 (5th
    Cir. 2009) (“It is well-settled in this circuit that an amicus curiae generally cannot expand

    Service focused its resources on locating additional ephemeral ponds. It
    explained that it prioritized ephemeral ponds because of their rarity and great
    importance for breeding, and because they are very difficult to replicate
    artificially. See Final Designation, 77 Fed. Reg. at 35,123–24. The Service
    further explained that additional breeding populations are necessary for the
    frog’s recovery and to prevent excessive inbreeding. See 
    id. at 35,121,
    35,123–
    24. Although the Service has created one artificial ephemeral pond in the
    DeSoto National Forest in Mississippi, this artificial pond took ten years to
    construct, and it is still unclear whether it will be successful as a breeding site.
    See 
    id. at 35,123.
    In contrast, as an expert explained at the public hearing on
    the Revised Proposal, it is “much easier to restore a terrestrial habitat for the
    gopher frog than to restore or build breeding ponds.” See also 
    id. at 35123
    (“Isolated, ephemeral ponds that can be used as the focal point for establishing
    these populations are rare, and this is a limiting factor in dusky gopher frog
    recovery.”). As the Service explained in the Final Designation, “[a]lthough
    [DeSoto] is crucial to the survival of the frog because the majority of the
    remaining frogs occur there, recovery of the species will require populations of
    dusky gopher frog distributed across a broader portion of the species’ historic
    distribution.” 
    Id. at 35,125.
          The Service therefore searched for isolated, ephemeral ponds within the
    historical range of the frog in Alabama and Louisiana. See Final Designation,
    77 Fed. Reg. at 35,124. The area in Alabama where the frog once lived has
    since been replaced by a residential development. See 
    id. The Service
    noted
    that it was unable to find any breeding sites that the frog might use in the
    future in Alabama. See 
    id. In contrast,
    the Service explained that Unit 1’s five
    ephemeral ponds are “intact and of remarkable quality.” 
    Id. at 35,133.
    It noted
    that the ponds in Unit 1 “are in close proximity to each other, which would
    16

    Cons w/ No. 14-31021
    allow movement of adult gopher frogs between them” and would “provide
    metapopulation structure that supports long-term survival and population
    resiliency.” 
    Id. “Based on
    the best scientific information available to the
    Service,” the Service concluded that “the five ponds in Unit 1 provide breeding
    habitat that in its totality is not known to be present elsewhere within the
    historic range of the dusky gopher frog.” 
    Id. at 35,124.
          Finally, in addition to ephemeral ponds, dusky gopher frogs also require
    upland forested habitat and connected corridors that allow them to move
    between their breeding and nonbreeding habitats. See 
    id. at 35,131–32.
    Looking to the upland terrestrial habitat surrounding Unit 1’s ephemeral
    ponds, the Service relied on scientific measurements and data to draw a
    boundary around Unit 1. The Service used digital aerial photography to map
    the ponds and then to delineate critical-habitat units by demarcating a buffer
    zone around the ponds by a radius of 621 meters (or 2,037 feet). 
    Id. at 35,134.
    This value, which was based on data collected during multiple gopher frog
    studies, represented the median farthest distance that frogs had traveled from
    breeding sites (571 meters or 1,873 feet) plus an extra 50 meters (or 164 feet)
    “to minimize the edge effects of the surrounding land use.” 
    Id. The Service
    finally used aerial imagery to connect critical-habitat areas that were within
    1,000 meters (or 3,281 feet) of each other “to create routes for gene flow
    between breeding sites and metapopulation structure.” 
    Id. Altogether, the
    Service concluded:
    Unit 1 is essential to the conservation of the dusky gopher frog
    because it provides: (1) Breeding habitat for the dusky gopher frog
    in a landscape where the rarity of that habitat is a primary threat
    to the species; (2) a framework of breeding ponds that supports
    metapopulation structure important to the long-term survival of
    the dusky gopher frog; and (3) geographic distance from extant
    17

    dusky gopher frog populations, which likely provides protection
    from environmental stochasticity.
    
    Id. As Judge
    Feldman reasoned below, “[the Service’s] finding that the unique
    ponds located on Unit 1 are essential for the frog’s recovery is supported by the
    ESA and by the record; it therefore must be upheld in law as a permissible
    interpretation of the ESA.” Markle 
    Interests, 40 F. Supp. 3d at 761
    (applying
    Chevron deference).
    On appeal, the Landowners do not dispute the scientific or factual
    support for the Service’s determination that Unit 1 is essential. 14 Instead, they
    argue that the Service “exceeded its statutory authority” under the ESA and
    acted arbitrarily and capriciously when it designated Unit 1 as critical habitat
    because Unit 1 is not currently habitable, nor “currently supporting the
    conservation of the species in any way,” nor reasonably likely to support the
    conservation of the species in the “foreseeable future.” They contend that such
    land cannot rationally be called “essential for the conservation of the species,”
    because if it can be, then the Service would have “nearly limitless authority to
    burden private lands with a critical habitat designation.”
    As Judge Feldman noted, Congress has not defined the word “essential”
    in the ESA. Hence the Service has the authority to interpret the term. See
    Sierra 
    Club, 245 F.3d at 438
    (“Once a species has been listed as endangered . . .
    the ESA states that the Secretary ‘shall’ designate a critical habitat ‘to the
    maximum extent prudent or determinable.’ The ESA leaves to the Secretary
    the task of defining ‘prudent’ and ‘determinable.’” (quoting 16 U.S.C.
    § 1533(h))). To issue a formal rule designating critical habitat for the frog, the
    Amici do challenge the scope of the Unit 1 designation, but we will not consider this
    14
    argument because the Landowners did not raise it on appeal. See World Wide St. Preachers

    Service necessarily had to interpret and apply the applicable ESA provisions,
    including the word “essential.” See Nat'l R.R. Passenger Corp. v. Boston &
    Maine Corp., 
    503 U.S. 407
    , 420 (1992) (“[W]e defer to an interpretation which
    was a necessary presupposition of the [agency]’s decision.”); cf. S.D. ex rel.
    Dickson v. Hood, 
    391 F.3d 581
    , 596 & n.13 (5th Cir. 2004) (explaining that,
    when the Centers for Medicare and Medicaid Services are charged with
    reviewing and approving state Medicaid plans to ensure that the plans conform
    to the Act, the agency implicitly interprets the Act when granting approvals).
    The Service issued the designation as a formal agency rule after two rounds of
    notice and comment. Thus, the Service’s interpretation of the term “essential”
    is entitled to Chevron deference. See Home 
    Builders, 551 U.S. at 665
    (applying
    Chevron deference in the context of the ESA); 
    Chevron, 467 U.S. at 842
    –44.
    When, as here, “an agency’s decision qualifies for Chevron deference, we
    will accept the agency’s reasonable construction of an ambiguous statute that
    the agency is charged with administering.” 
    Knapp, 796 F.3d at 455
    . The
    question presented, then, is whether the Landowners have demonstrated that
    the Service interpreted the ESA unreasonably when it deemed Unit 1
    “essential” for the conservation of the dusky gopher frog. Although the
    Landowners acknowledge that “the Service undoubtedly has some discretion
    in interpreting the statutory language of the ESA,” they contend that the
    Service “does not have the authority to apply the term ‘essential’ in a way that
    is contrary to its plain meaning.” The Landowners do not explain what they
    think the “plain meaning” of essential is, however, save to argue, circularly,
    that we must “insist[ ]” that “‘essential’ must truly mean essential.” 15
    15The dissent instead introduces two alternative definitions of “essential” from Black’s
    Law Dictionary: “2. Of the utmost importance; basic and necessary. 3. Having real existence,
    actual.” Dissent at 5. The dissent then goes on to cite MCI Telecommunications Corp. v. Am.

    We consider first their argument that it is an unreasonable
    interpretation of the ESA to describe Unit 1 as essential for the conservation
    of the dusky gopher frog when Unit 1 is not currently habitable by the frog.
    The statute does not support this argument. There is no habitability
    requirement in the text of the ESA or the implementing regulations. The
    statute requires the Service to designate “essential” areas, without further
    defining “essential” to mean “habitable.” See Bear Valley Mut. Water Co. v.
    Jewell, 
    790 F.3d 977
    , 994 (9th Cir. 2015) (upholding the designation of
    unoccupied critical habitat, even though the area was not habitable by the
    endangered species). The Landowners’ proposed extra-textual limit on the
    designation of unoccupied land—habitability—effectively conflates the
    standard for designating unoccupied land with the standard for designating
    occupied land. See Dep’t of Homeland Sec. v. MacLean, 
    135 S. Ct. 913
    , 919
    (2015) (“Congress generally acts intentionally when it uses particular language
    in one section of a statute but omits it in another.”). As Judge Feldman
    insightfully observed, “[their position] is . . . contrary to the ESA; [the
    Landowners] equate what Congress plainly differentiates: the ESA defines two
    distinct types of critical habitat, occupied and unoccupied; only occupied
    habitat must contain all of the relevant [physical or biological features].”
    Markle 
    Interests, 40 F. Supp. 3d at 761
    . Thus, the plain text of the ESA does
    not require Unit 1 to be habitable. “[R]ather,” as Judge Feldman elaborated,
    Tel. & Tel. Co., 
    512 U.S. 218
    , 229 (1994), for the proposition that “an agency's interpretation
    of a statute is not entitled to deference when it goes beyond the meaning that the statute can
    bear.” Dissent at 7. The dissent’s own alternative definitions distinguish MCI from this case.
    In MCI, the agency advanced an interpretation of the word “modify” that flatly contradicted
    the definition provided by “[v]irtually every dictionary [the Court] was aware of.” 
    Id. at 225.
    Here, in contrast, one of the dissent’s own definitions of essential—“of the utmost importance;
    basic and necessary”—describes well a close system of ephemeral ponds, per the scientific
    consensus that the Service relied upon. See infra note 20.

    the conservation of the species.’” 
    Id. at 762
    (quoting 50 C.F.R. § 424.12(e)).
    Here, the Service provided scientific data to support its finding that Unit 1 is
    essential, and as Judge Feldman held, “[the Landowners] have not
    demonstrated that [the Service’s] findings are implausible.” 
    Id. Thus, the
    Landowners have not shown that the Service employed an unreasonable
    interpretation of the ESA when it found that the currently uninhabitable Unit
    1 was essential for the conservation of the dusky gopher frog and designated
    the land as critical habitat.
    We consider next the argument that it is an unreasonable interpretation
    of the ESA to describe Unit 1 as essential for the conservation of the dusky
    gopher frog when Unit 1 “is not currently supporting the conservation of the
    species in any way and the Service has no reasonable basis to believe that it
    will do so at any point in the foreseeable future.” Like their proposed
    habitability requirement, the Landowners’ proposed temporal requirement—
    considering whether the frog can live on the land “currently” or in the
    “foreseeable future”—also lacks legal support and is undermined by the ESA’s
    text. The ESA’s critical-habitat provisions do not require the Service to know
    when a protected species will be conserved as a result of the designation. The
    Service is required to designate unoccupied areas as critical habitat if these
    areas are “essential for the conservation of the species.” 16 U.S.C.
    § 1532(5)(A)(ii). The statute defines “conservation” as “the use of all methods
    and procedures which are necessary to bring any endangered species . . . to the
    point at which the measures provided . . . are no longer necessary.”

    when a viable population of dusky gopher frogs will be achieved, as indifferent
    and overreaching by the government as it appears, does not serve to invalidate
    its finding that Unit 1 was part of the minimum required habitat for the frog’s
    conservation.” Markle 
    Interests, 40 F. Supp. 3d at 762
    –63. We also note that,
    in contrast to the habitat-designation provision at issue here, the ESA’s
    recovery-plan provisions do require the Service to estimate when a species will
    be conserved. See 16 U.S.C. § 1533(f)(1)(B)(iii). Congress’s inclusion of a
    conservation-timeline requirement for recovery plans, but omission of it for
    critical-habitat designations, further underscores the weakness of the
    Landowners’ argument. See 
    MacLean, 135 S. Ct. at 919
    . 16
    Moreover, we observe that the Landowners’ proposed temporal
    requirement could effectively exclude all private land not currently occupied
    16We further note that it was logical for Congress to require the Service to estimate a
    timeline for achieving its conservation goals in a recovery plan but not to impose that
    requirement for critical-habitat designations because there is no deadline for creating a
    recovery plan, but there is a one-year deadline for designating critical habitat. See 16 U.S.C.

    by the species from critical-habitat designations. By the Landowners’ logic,
    private landowners could trump the Service’s scientific determination that
    unoccupied habitat is essential for the conservation of a species so long as they
    declare that they are not currently willing to modify habitat to make it
    habitable and that they will not be willing to make modifications in the
    foreseeable future. Their logic would also seem to allow landowners whose land
    is immediately habitable to block a critical-habitat designation merely by
    declaring that they will not—now or ever—permit the reintroduction of the
    species to their land. The Landowners’ focus on private-party cooperation as
    part of the definition of “essential” finds no support in the text of the ESA.
    Nothing in the ESA requires that private landowners be willing to participate
    in species conservation. 17 Summing up the Landowners’ arguments on this
    point, Judge Feldman observed that the Landowners “effectively ask the Court
    to endorse—contrary to the express terms and scope of the statute—a private
    landowner exemption from unoccupied critical-habitat designations. This, the
    Third Branch, is the wrong audience for addressing this matter of policy.”
    17 The statute requires the Service to base its decision on “the best scientific data
    available.” 16 U.S.C. § 1533(b)(2). Here, the Service followed that command and made an
    objective feasibility determination that the uplands surrounding the ephemeral ponds,
    although currently lacking “the essential physical or biological features of critical habitat,”
    are “restorable with reasonable effort.” Final Designation, 77 Fed. Reg. at 35,135. We find no
    basis in the text of the statute for the “reasonable probability” test introduced by the dissent,
    which looks to “many factors” including “whether a reasonable landowner would be likely to
    undertake the necessary modifications.” Dissent at 13. Although a “reasonable landowner”
    test has the sound of an objective test, the dissent does not make clear how such a test would
    be applied in practice, nor how it would avoid taking into account the subjective intentions of
    specific landowners. For example, the dissent says that in a scenario in which a
    “landowner . . . enter[s] into an agreement to modify land so that it might be used as habitat,
    there would be nothing ‘subjective’ in concluding that it is reasonably probable that the land
    will actually be used at habitat.” Dissent at 13. A test that can come out differently depending
    on the actual plans of specific landowners is, by definition, subjective.

    n.40. We agree. Thus, the Landowners
    have not shown that the Service employed an unreasonable interpretation of
    the ESA when it found that Unit 1 was essential for the conservation of the
    dusky gopher frog without first establishing that Unit 1 currently supports, or
    in the “foreseeable future” will support, the conservation of the dusky gopher
    frog.
    We next consider the argument that that the Service has interpreted the
    word “essential” unreasonably because its interpretation fails to place
    “meaningful limits” on the Service’s power under the ESA. Thus, we consider
    whether, in designating Unit 1, the Service abided the meaningful limits that
    the ESA and the agency’s implementing regulations set on the Service’s
    authority to designate unoccupied areas as critical habitat. Under the
    regulations in effect at the time that Unit 1 was designated, the Service had to
    find that the species’s occupied habitat was inadequate before it could even
    consider designating unoccupied habitat as critical. 50 C.F.R. § 424.12(e). In
    part, this preliminary determination provided a limit to the term “essential”
    as it relates to unoccupied areas. Unoccupied areas could be essential only if
    occupied areas were found to be inadequate for conserving the species. See Bear
    Valley Mut. Water 
    Co., 790 F.3d at 994
    (recognizing that the inadequacy and
    essentiality requirements overlap). Here, the Service made that threshold
    inadequacy determination—a determination that the Landowners do not
    challenge.
    Next, under the ESA itself, the Service can designate unoccupied land
    only if it is “essential for the conservation of the species.” 16 U.S.C.
    § 1532(5)(A)(ii). “Conservation” is defined as “the use of all methods and
    procedures which are necessary to bring any endangered species . . . to the
    point at which the measures provided . . . are no longer necessary.” 
    Id. 24 Case:

    § 1532(3) (emphasis added). In light of this definition, we find implausible the
    Landowners’ parade of horribles in which they suggest that, if the Service can
    designate an area like Unit 1 as critical habitat, it could designate “much of
    the land in the United States” as well. They contend that “[b]ecause any land
    may conceivably be turned into suitable habitat with enough time, effort, and
    resources, th[e] [Service’s] interpretation gives the Service nearly limitless
    authority to burden private lands with a critical habitat designation.” But we
    find it hard to see how the Service would be able to satisfactorily explain why
    randomly chosen land—whether an empty field or, as the Landowners suggest,
    land covered in “buildings” and “pavement”—would be any more “necessary”
    to a given species’ recovery than any other arbitrarily chosen empty field or
    paved lot. 18 Here, the Service confirmed through peer review and two rounds
    of notice and comment a scientific consensus as to the presence and rarity of a
    critical (and difficult to reproduce) feature—the ephemeral ponds—which
    18  Nor do we see how the Service could justify designating land that objectively—that
    is, for scientific reasons—could never contribute to the conservation of a species—say, for
    example, if the ephemeral ponds were located within a toxic spill zone that scientists
    concluded could not be remediated. Where we differ critically from the dissent is on the
    question whether the ESA provides any basis for taking into account subjective third-party
    intentions when determining whether land could contribute to the conservation of a species.
    We hold that it does not. Under our approach, it would still be arbitrary and capricious for
    the Service to label as essential land that is objectively impossible to use for conservation. See

    justified its finding that Unit 1 was essential for the conservation of the dusky
    gopher frog. 19
    In addition, the ESA requires the Service to base its finding of
    essentiality on “the best scientific data available.” 
    Id. § 1533(b)(2).
    This
    requirement further cabins the Service’s power to make critical-habitat
    designations. Here, the Final Designation was based on the scientific expertise
    of the agency’s biologists and outside gopher frog specialists. If this scientific
    support were not in the record, the designation could not stand. 20 But that is
    19  We fail to see how the Service would be able to similarly justify as rational an
    essentiality finding as to arbitrarily chosen land. In contrast, the dissent, similar to the
    Landowners, contends that “[i]t is easily conceivable that ‘the best scientific data available’
    would lead scientists to conclude that an empty field that is not currently habitable could be
    altered to become habitat for an endangered species.” Dissent at 13-14. Even assuming that
    to be true, it does not follow that scientists or the Service would or could then reasonably call
    an empty field essential for the conservation of a species. If the field in question were no
    different than any other empty field, what would make it essential? Presumably, if the field
    could be modified into suitable habitat, so could any of the one hundred or one thousand other
    similar fields. If the fields are fungible, it would be arbitrary for the Service to label any
    single one “essential” to the conservation of a species. It is only by overlooking this point that
    the dissent can maintain that our approval of the Service’s reading of “essential” will “mean[ ]
    that virtually any part of the United States could be designated as ‘critical habitat’ for any
    given endangered species so long as the property could be modified in a way that would
    support introduction and subsequent conservation of the species on it.” Dissent at 6
    (emphasis added).
    20 The dissent also takes aim at our acceptance of the Service’s scientifically grounded
    essentiality finding in this case, contending that, under our decision, the Service can
    designate any land as critical habitat whenever it contains a single one of the “physical or
    biological features” essential to the conservation of the species at issue. 16 U.S.C.
    § 1532(5)(A)(i). Dissent at 14-15. We create no such generalized rule. We hold only that in
    this case, substantial, consensus, scientific evidence in the record supports the Service’s
    conclusion that the ephemeral ponds present on Unit 1 are essential for the conservation of
    the dusky gopher frog. See, e.g., Final Designation, 77 Fed. Reg. at 35123 (summarizing the
    scientific consensus that the rarity of isolated, ephemeral ponds “is a limiting factor in dusky
    gopher frog recovery”). The ponds cannot be separated from the land that contains them.
    Thus, if the ponds are essential, then Unit 1, which contains the ponds, is essential for the
    conservation of the dusky gopher frog. In general, the dissent seeks to decouple the Service’s
    “essentiality” finding from its scientific determination process, turning it into a purely legal
    standard. We decline to do so, with the good reason that the ESA specifically requires that
    critical habitat determinations be based on “scientific data.” See 16 U.S.C. § 1533(b)(2).

    Case: 14-31008       Document: 00513573768         Page: 27     Date Filed: 06/30/2016

    Cons w/ No. 14-31021
    not the situation here, and the Landowners do not challenge the consensus
    scientific data on which the Service relied. The Landowners have not shown
    that the Service employed an interpretation of the ESA that is inconsistent
    with the meaningful limits that the ESA and the agency’s implementing
    regulations set on the Service’s authority to designate unoccupied areas as
    critical habitat. 21
    In sum, the Landowners have not established that the Service
    interpreted the ESA unreasonably—and was thus undeserving of Chevron
    deference—when it found that Unit 1 was essential for the conservation of the
    dusky gopher frog. Likewise, the Landowners have not shown that the
    Service’s essentiality finding failed to “satisfy minimum standards of
    rationality,” 10 Ring 
    Precision, 722 F.3d at 723
    , which means that they have
    not shown that the Service acted arbitrarily or capriciously, either.
    Finally, the Landowners contend that it is improper to protect Unit 1
    with a critical-habitat designation when there are other ways to ensure that
    Unit 1 will assist with the conservation of the gopher frog. It is true that the
    Service could manage Unit 1 by purchasing the land. See 16 U.S.C. § 1534(a).
    But the legal availability of other statutory conservation mechanisms, some
    arguably more intrusive of private property interests, does not undercut the
    Service’s separate statutory duty to designate as critical habitat unoccupied
    areas that are essential for the conservation of the species. See 
    id. 21In response
    to the dissent’s policy concerns about ever-expanding designations, we
    also note that the ESA limits critical-habitat designations on the back end as well, because
    successful conservation through critical-habitat designation ultimately works towards
    undesignation. See, e.g., Removal of the Louisiana Black Bear From the Federal List of
    Endangered and Threatened Wildlife and Removal of Similarity-of-Appearance Protections
    for the American Black Bear, 81 Fed. Reg. 13,124, 13,171 (March 11, 2016) (to be codified at
    50 C.F.R. pt. 17) (final rule removing Louisiana black bear from endangered species list and,
    accordingly, “removing the designated critical habitat for the Louisiana black bear”).

    In sum, the designation of Unit 1 as critical habitat was not arbitrary
    and capricious nor based upon an unreasonable interpretation of the ESA. The
    Service reasonably determined (1) that designating occupied habitat alone
    would be inadequate to ensure the conservation of the dusky gopher frog and
    (2) that Unit 1 is essential for the conservation of the frog. We thus agree with
    Judge Feldman: “the law authorizes such action and . . . the government has
    acted within the law.” Markle 
    Interests, 40 F. Supp. 3d at 759
    –60.
    C. Decision Not to Exclude Unit 1
    In addition to attacking the Service’s conclusion that Unit 1 is essential
    for the conservation of the dusky gopher frog, the Landowners also challenge
    the Service’s conclusion that the economic impacts on Unit 1 are not
    disproportionate. See Final Designation, 77 Fed. Reg. at 35,141. The
    Landowners argue that because the benefits of excluding Unit 1 from the
    designation clearly outweigh the benefits of including it in the designation, the
    Service’s decision is arbitrary and capricious. The Landowners contend that
    because Unit 1 is not currently habitable by the dusky gopher frog, the land
    provides no biological benefit to the frog. They emphasize that Unit 1, by
    contrast, bears a potential loss of development value of up to $33.9 million over
    twenty years.
    The ESA mandates that the Service “tak[e] into consideration the
    economic impact . . . of specifying any particular area as critical habitat.” 16
    U.S.C. § 1533(b)(2). After it takes this impact into consideration, the Service
    may exclude any area from critical habitat if [it] determines that
    the benefits of such exclusion outweigh the benefits of specifying
    28

    such area as part of the critical habitat, unless [it] determines,

    the failure to designate such area as critical habitat will result in
    the extinction of the species concerned.
    
    Id. (emphasis added).
    The Service argues that once it has fulfilled its statutory
    obligation to consider economic impacts, a decision to not exclude an area is
    discretionary and thus not reviewable in court. The Service is correct. Under
    the APA, decisions “committed to agency discretion by law” are not reviewable
    in federal court. 5 U.S.C. § 701(a)(2). An action is committed to agency
    discretion when there is “no meaningful standard against which to judge the
    agency’s exercise of discretion.” Heckler v. Chaney, 
    470 U.S. 821
    , 830 (1985).
    “[I]f no judicially manageable standards are available for judging how and
    when an agency should exercise its discretion, then it is impossible to evaluate
    agency action for ‘abuse of discretion.’” 
    Id. The only
    other circuit court that has confronted this issue has recognized
    that there are no manageable standards for reviewing the Service’s decision
    not to exercise its discretionary authority to exclude an area from a critical-
    habitat designation. See Bear Valley Mut. Water 
    Co., 790 F.3d at 989
    –90. It
    therefore held that the decision not to exclude is unreviewable. Id.; see also

    (N.D. Cal. Nov. 30, 2012). Similarly, every district court that has
    addressed this issue has also held that the decision not to exclude is not subject
    to judicial review. See Aina Nui Corp. v. Jewell,

    substantive standards by which to review the [agency’s] decisions not to
    exclude certain tracts based on economic or other considerations, and those

    We see no reason to chart a new path on this issue in concluding that we
    cannot review the Service’s decision not to exercise its discretion to exclude
    Unit 1 from the critical-habitat designation. Section 1533(b)(2) articulates a
    standard for reviewing the Service’s decision to exclude an area. But the
    statute is silent on a standard for reviewing the Service’s decision to not
    exclude an area. Put another way, the section establishes a discretionary
    process by which the Service may exclude areas from designation, but it does
    not articulate any standard governing when the Service must exclude an area
    from designation. See Bear Valley Mut. Water 
    Co., 790 F.3d at 989
    (“[W]here a
    statute is written in the permissive, an agency’s decision not to act is
    considered presumptively unreviewable because courts lack ‘a focus for judicial
    review . . . to determine whether the agency exceeded its statutory powers.’”
    (quoting 
    Heckler, 470 U.S. at 832
    )). Thus, even were we to assume that the
    Landowners are correct that the economic benefits of exclusion outweigh the
    conservation benefits of designation, the Service is still not obligated to exclude
    Unit 1. That decision is committed to the agency’s discretion and is not
    reviewable.
    The Supreme Court’s recent decision in Michigan v. EPA, 
    135 S. Ct. 2699
    (2015), does not compel a contrary conclusion. In Michigan, the Environmental
    Protection Agency (“EPA”) had interpreted a provision of the Clean Air Act to
    not require the consideration of costs when deciding whether to regulate
    30

    that it was not requiring the agency “to conduct a formal cost-benefit analysis
    in which each advantage and disadvantage is assigned a monetary value.” 
    Id. at 2711.
    The Court further explained that “[i]t will be up to the Agency to
    decide (as always, within the limits of reasonable interpretation) how to

    Id. Unlike the
    provision of the Clean Air Act at issue in Michigan, the ESA

    requirement by commissioning an economic report by Industrial Economics,

    refine that analysis, it included three impact scenarios. The report noted that
    Unit 1 bears a potential loss of development value ranging from $0 to $33.9
    million over twenty years. See Final Designation, 77 Fed. Reg. at 35,140–41;
    This potential loss depends on a number of contingencies that may or may not
    arise, including future development projects, the nature of federal agency
    approval that is required for those projects, and possible limits that are
    imposed after any consultation that accompanies federal agency action. As has
    been recently recognized, the statute does not require a particular methodology
    for considering economic impact. See Bldg. Indus. Ass’n of Bay Area, 
    2015 WL 4080761
    , at *5–6. And here on appeal, the Landowners do not challenge the
    methodology that the Service used when analyzing the economic impact on
    Unit 1; instead, the Landowners challenge the Service’s bottom-line conclusion
    not to exclude Unit 1 on the basis of that economic impact. That conclusion is
    not reviewable.

    II.   Commerce Clause
    Having concluded that the Service’s designation of Unit 1 as critical
    habitat was not arbitrary and capricious, we must next consider the
    Landowners’ alternative argument that the ESA exceeds Congress’s powers
    under the Commerce Clause. The Commerce Clause gives Congress the power
    “[t]o regulate Commerce . . . among the several States.” U.S. Const. art. I, § 8,
    cl. 3. In United States v. Lopez, the Supreme Court defined three broad
    categories of federal legislation that are consistent with this power. 
    514 U.S. 549
    , 558 (1995). This case concerns the third Lopez category—that is, whether
    the federal action “substantially affect[s] interstate commerce.” 
    Id. at 558–59
    (citations omitted).
    The Landowners concede that, “properly limited and confined to the
    statutory definition,” the critical-habitat provision of the ESA is a
    constitutional exercise of Congress’s Commerce Clause authority. They
    maintain, however, that the designation of Unit 1 as critical habitat for the
    dusky gopher frog exceeds the scope of an otherwise constitutional power.
    Viewed this narrowly, the designation of Unit 1 is intrastate (not interstate)
    activity. The Landowners further argue that “[t]here is simply no rational basis
    to conclude that the use of Unit 1 will substantially affect interstate
    commerce.” In support of this narrow framing of the issue, the Landowners
    imply that it is inappropriate to aggregate the effect of designating Unit 1 with
    the effect of all other critical-habitat designations nationwide. Instead, the
    Landowners argue that we should analyze the commercial impact of the Unit
    1 designation independent of all other designations. But as Judge Feldman
    explained, “each application of the ESA is not itself subject to the same tests
    for determining whether the underlying statute is a constitutional exercise of
    the Commerce Clause.” Markle 
    Interests, 40 F. Supp. 3d at 758
    . We agree with

    Cons w/ No. 14-31021
    Judge Feldman that “the [Landowners’] constitutional claim is foreclosed by
    binding precedent.” 
    Id. The Supreme
    Court has outlined four considerations that are relevant
    when analyzing whether Congress can regulate purely intrastate activities
    under the third Lopez prong. See United States v. Morrison, 
    529 U.S. 598
    , 609–
    12 (2000). First, courts should consider whether the intrastate activity “in
    question has been some sort of economic endeavor.” 
    Id. at 611.
    Second, courts
    should consider whether there is an “express jurisdictional element” in the
    statute that might limit its application to instances that “have an explicit
    connection with or effect on interstate commerce.” 
    Id. at 611–12.
    The next
    consideration that should inform the analysis is legislative history and
    congressional findings on the effect that the subject of the legislation has on
    interstate commerce. 
    Id. at 612.
    Finally, courts should evaluate whether the
    link between the intrastate activity and its effect on interstate commerce is
    attenuated. 
    Id. The Landowners’
    constitutional challenge can be distilled to
    the question of whether we can properly analyze the Unit 1 designation
    aggregated with all other critical-habitat designations nationwide. This
    question falls under the first consideration articulated in Morrison. Because
    the Landowners concede that the critical-habitat provision of the ESA is
    “within the legitimate powers of Congress,” we need focus on only the first
    consideration if we find that aggregation is appropriate.
    The first consideration is whether the regulated intrastate activity is
    economic or commercial in nature. 
    Id. at 611.
    The question thus arises: what
    is the regulated activity that we must analyze? See GDF Realty Invs., Ltd. v.
    Norton, 
    326 F.3d 622
    , 633 (5th Cir. 2003). In GDF Realty, where we examined
    33
    Case: 14-31008        Document: 00513573768           Page: 34      Date Filed: 06/30/2016
    No. 14-31008
    Cons w/ No. 14-31021
    the “take” provision 22 of the ESA, we emphasized that we had to analyze the
    regulation of endangered species takes, not the commercial motivations of the
    plaintiff–developers who were challenging the statute. 
    Id. at 636.
    Applying
    GDF Realty here, the regulated activity in question is the designation of Unit
    1 as critical habitat, not the Landowners’ long-term development plans.
    The next issue is whether the designation of Unit 1 as critical habitat is
    economic or commercial in nature. “[W]hether an activity is economic or
    commercial is to be given a broad reading in this context.” 
    Id. at 638.
    In certain
    cases, an intrastate activity may have a direct relationship to commerce and
    therefore the intrastate activity alone may substantially affect interstate
    commerce. Alternatively, “the regulation can reach intrastate commercial
    activity that by itself is too trivial to have a substantial effect on interstate
    commerce but which, when aggregated with similar and related activity, can
    substantially affect interstate commerce.” United States v. Ho, 
    311 F.3d 589
    ,
    599 (5th Cir. 2002).
    The designation of Unit 1 alone may not have a direct relationship to
    commerce, but under the aggregation principle, the designation of Unit 1
    survives constitutional muster. Under this principle, the intrastate activity
    can be regulated if it is “an essential part of a larger regulation of economic
    activity, in which the regulatory scheme could be undercut unless the
    intrastate activity were regulated.” Gonzales v. Raich, 
    545 U.S. 1
    , 36 (2005)
    (quoting 
    Lopez, 514 U.S. at 561
    ). Thus, there are two factors we must consider:
    (1) whether the provision mandating the designation of critical habitat is part
    22See 16 U.S.C. § 1532(19) (“The term ‘take’ means to harass, harm, pursue, hunt,
    shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct.”); 
    id. § 1538(a)(1)(B)
    (making it unlawful to “take” an endangered species).
    34

    No. 14-31008
    Cons w/ No. 14-31021
    of an economic regulatory scheme, and (2) whether designation is essential to
    that scheme.
    We have already concluded that the ESA is an economic regulatory
    scheme. See GDF 
    Realty, 326 F.3d at 639
    (“ESA’s protection of endangered
    species is economic in nature.”); 
    id. at 640
    (“ESA is an economic regulatory
    scheme . . . .”). Congress enacted the ESA to curb species extinction “as a
    consequence of economic growth and development untempered by adequate
    concern and conservation.” 16 U.S.C. § 1531(a)(1). Because the ESA’s drafters
    sought to protect the “incalculable” value of biodiversity, the ESA prohibits
    interstate   and     foreign   commerce      in   endangered     species.   See   
    id. § 1538(a)(1)(E)–(F);
    GDF 
    Realty, 326 F.3d at 639
    (citation omitted). Finally,
    habitat protection and management—which often intersect with commercial
    development—underscore the economic nature of the ESA and its critical-
    habitat provision. See 16 U.S.C. § 1533(f)(1)(A) (requiring that the Secretary
    prioritize implementing recovery plans for “those species that are, or may be,
    in conflict with construction or other development projects or other forms of
    economic activity”); see also 
    id. § 1533(a)(1)(B)
    (listing the “overutilization [of
    a species] for commercial . . . purposes” as one of the factors endangering or
    threatening species).
    But it is not sufficient that the ESA is an economic regulatory scheme.
    The critical-habitat provision must also be an essential component of the ESA.
    If the process of designating critical habitat is “an essential part of a larger
    regulation of economic activity,” then whether that process—designation—
    “ensnares some purely intrastate activity is of no moment.” 
    Raich, 545 U.S. at 22
    . “[T]he de minimis character of individual instances arising under that
    statute is of no consequence.” 
    Id. at 17
    (citations and internal quotation marks
    omitted). When Congress has regulated a class of activities, we “have no power
    35
    Case: 14-31008     Document: 00513573768     Page: 36    Date Filed: 06/30/2016

    Cons w/ No. 14-31021
    to excise, as trivial, individual instances of the class.” 
    Id. at 23
    (citation and
    internal quotation marks omitted). We conclude that designating critical
    habitat is an essential part of the ESA’s economic regulatory scheme.
    This conclusion is consistent with our analysis of the ESA’s “take”
    provision in GDF Realty. There, we held that “takes” of an endangered species
    that lived only in Texas could be aggregated with takes of other endangered
    species nationwide to survive a Commerce Clause challenge. GDF 
    Realty, 326 F.3d at 640
    –41. That case concerned the Service’s regulation of takes of six
    subterranean endangered species (“the Cave Species”) located solely in two
    counties in Texas. 
    Id. at 625.
    Similar to the Landowners here, the owners of
    some of the land under which these species lived wanted to develop the land
    into a commercial and residential area; they sued the government, claiming
    that the take provision of the ESA, as applied to the Cave Species, exceeded
    the boundaries of the Commerce Clause. 
    Id. at 624,
    626. Addressing this claim,
    we upheld the take provision. We explained that, in the aggregate, takes of all
    endangered species have a substantial effect on interstate commerce. See 
    id. at 638–40.
    Because of the “interdependence of [all] species,” we held that
    regulating the takes of the Cave Species was an essential part of the larger
    regulatory scheme of the ESA, in that, without this regulation, the regulatory
    scheme could be undercut by piecemeal extinctions. 
    Id. at 639–40.
    Every other
    circuit court that has addressed similar challenges has also upheld the ESA as
    a valid exercise of Congress’s Commerce Clause power. See Gibbs v. Babbitt,

    , 1049–57 (D.C. Cir. 1997). The Landowners have not
    identified any federal court of appeals that has held otherwise.
    This caselaw compels the same conclusion here. For one, we see no basis
    to distinguish the ESA’s prohibition on “takes” from the ESA’s mandate to
    designate critical habitat. As Congress recognized, one of the primary factors
    causing a species to become endangered is “the present or threatened
    destruction, modification, or curtailment of its habitat or range.” 16 U.S.C.
    § 1533(a)(1)(A). Because of the link between species survival and habitat
    preservation, the statute imposes a mandatory duty on the Service to designate
    critical habitat for endangered species “to the maximum extent prudent and
    determinable.” 
    Id. § 1533(a)(3)(A).
    Indeed, the ESA includes an express
    purpose of conserving “the ecosystems upon which endangered species . . .
    depend.” 
    Id. § 1531(b);
    see also GDF 
    Realty, 326 F.3d at 640
    (“In fact, according
    to Congress, the ‘essential purpose’ of the ESA is ‘to protect the ecosystems
    upon which we and other species depend.’” (quoting H.R. Rep. No. 93–412, at
    10)). Allowing a particular critical habitat—one that the Service has already
    found to be essential for the conservation of the species—to escape designation
    would undercut the ESA’s scheme by leading to piecemeal destruction of
    critical habitat. We therefore conclude that the critical-habitat provision is an
    essential part of the ESA, without which the ESA’s regulatory scheme would
    be undercut. Cf. Ala.–Tombigbee Rivers 
    Coal., 477 F.3d at 1274
    (holding that
    “the ‘comprehensive scheme’ of species protection contained in the Endangered
    Species Act has a substantial effect on interstate commerce” and that the
    process of listing species as endangered or threatened is “an essential part of
    that larger regulation of economic activity” (citation and internal quotation
    marks omitted)).

    No. 14-31008
    Cons w/ No. 14-31021
    Given this conclusion, the designation of Unit 1 may be aggregated with
    all other critical-habitat designations. As Judge Feldman correctly observed,
    “[w]here the class of activities is regulated and that class is within the reach
    of federal power, the courts have no power to excise, as trivial, individual
    instances of the class.” Markle 
    Interests, 40 F. Supp. 3d at 759
    (alteration in
    original) (quoting 
    Raich, 545 U.S. at 23
    ) (internal quotation marks omitted).
    “[W]hen a general regulatory statute bears a substantial relation to commerce,
    the de minimis character of individual instances arising under that statute is
    of no consequence.” 
    Raich, 545 U.S. at 17
    (citations and internal quotation
    marks omitted). We therefore will not look at the designation of Unit 1 in
    isolation, but instead we consider it aggregated with all other critical-habitat
    designations. Judge Feldman reached the same conclusion, explaining that,
    “[a]ggregating the regulation of activities that adversely modify the frog’s
    critical habitat”—including the isolated designation of Unit 1—“with the
    regulation of activities that affect other listed species’ habitat, the designation
    of critical habitat by the [Service] is a constitutionally valid application of a
    constitutionally valid Commerce Clause regulatory scheme.” Markle 
    Interests, 40 F. Supp. 3d at 759
    . Because the Landowners concede that the critical-
    habitat provision of the ESA is a valid exercise of Congress’s Commerce Clause
    authority, we can likewise conclude that the application of the ESA’s critical-
    habitat provision to Unit 1 is a constitutional exercise of the Commerce Clause
    power. 23
    23 Although the Landowners’ concession truncates our analysis, we observe that the
    other three considerations articulated in Morrison also weigh in favor of concluding that the
    critical-habitat provision of the ESA is constitutional as applied to the dusky gopher frog.
    Although there is no jurisdictional element in the statute limiting its application to instances
    affecting interstate commerce, the “interdependence of species” underscores that critical-
    habitat designations affect interstate commerce. GDF 
    Realty, 326 F.3d at 640
    . In this sense,

    III.    National Environmental Policy Act
    Finally, the Landowners contend that the Service violated NEPA by
    failing to prepare an environmental impact statement before designating Unit
    1 as critical habitat. If proposed federal action will “significantly affect[ ] the
    quality of the human environment,” NEPA requires the relevant federal
    agency to provide an environmental impact statement for the proposed action.
    42 U.S.C. § 4332(2)(C). In Sabine River Authority, we explained that an
    environmental impact statement “is not required for non major action or a
    major action which does not have significant impact on the 
    environment.” 951 F.2d at 677
    (citation and internal quotation marks omitted). This standard
    the ESA’s critical-habitat provision “is limited to instances which ‘have an explicit connection
    with or effect on interstate commerce.’” 
    Id. (quoting Morrison,
    529 U.S. at 611–12).
    Next, the congressional findings, legislative history, and statutory provisions indicate
    that the regulated activity has an effect on interstate commerce. See 16 U.S.C. § 1531(a)(1)
    (“The Congress finds and declares that . . . various species of fish, wildlife, and plants in the
    United States have been rendered extinct as a consequence of economic growth and
    development untempered by adequate concern and conservation . . . .”); 
    id. § 1533(a)(1)(A)–
    (B) (acknowledging “the present or threatened destruction, modification, or curtailment of [a
    species’s] habitat or its range” and the “overutilization [of species] for commercial . . .
    purposes” as factors leading to species endangerment); Tenn. Valley 
    Auth., 437 U.S. at 177
    –
    78 (summarizing the legislative history of the ESA); 
    Gibbs, 214 F.3d at 495
    (discussing the
    legislative history of the ESA and the possibility of renewing a commercial market in a
    species once it is no longer endangered or threatened (citing S. Rep. No. 91-526, at 3 (1969)));
    see also San Luis & Delta–Mendota Water 
    Auth., 638 F.3d at 1176
    .
    Finally, the link between critical-habitat designation and its effect on interstate
    commerce is not too attenuated. The ESA is economic in nature, and Congress has made
    critical-habitat designation a mandatory component of the regime. See 16 U.S.C.
    § 1533(a)(3)(A)(i) (stating that the Service “shall . . . designate any habitat of [an endangered]
    species which is then considered to be critical habitat” (emphasis added)). Moreover, as this
    case highlights, any future regulation of Unit 1 or other critical habitat would occur if the
    Landowners’ commercial development plans triggered Section 7 consultation. Thus, the link
    to interstate commerce is not too attenuated for purposes of Commerce Clause analysis. See
    
    Morrison, 529 U.S. at 611
    (explaining that the statutes challenged in Lopez and Morrison fell
    outside Congress’s Commerce Clause authority because “neither the actors nor their conduct
    ha[d] a commercial character, and neither the purposes nor the design of the statute ha[d]
    an evident commercial nexus” (citation and internal quotation marks omitted)). For these
    additional reasons, the application of the ESA’s critical-habitat provision is constitutional as
    applied to the dusky gopher frog.

    necessarily means that if federal action will not result in any change to the
    environment, then the action does not trigger NEPA’s impact-statement
    requirement. See 
    id. at 679
    (noting that federal action “did not effectuate any
    change to the environment which would otherwise trigger the need to prepare
    an [environmental impact statement]”); see also Metro. Edison Co. v. People
    Against Nuclear Energy, 
    460 U.S. 766
    , 774 (1983) (explaining that no
    environmental impact statement is required if health damage stemming from
    federal action “would not be proximately related to a change in the physical
    environment”); City of Dallas, Tex. v. Hall, 
    562 F.3d 712
    , 723 (5th Cir. 2009)
    (holding that an environmental impact statement was not required when the
    federal action “[did] not effect a change in the use or character of land or in the
    physical environment”).
    Judge Feldman correctly held that the designation of Unit 1 does not
    trigger NEPA’s impact-statement requirement because the designation “does
    not effect changes to the physical environment.” Markle Interests, 
    40 F. Supp. 3d
    at 768. The designation also does not require the Landowners to take action
    as a result of the designation. As Judge Feldman correctly observed, “the ESA
    statutory scheme makes clear that [the Service] has no authority to force
    private landowners to maintain or improve the habitat existing on their land.”
    
    Id. (footnote and
    citation omitted). We agree that the Service was not required
    to complete an environmental impact statement before designating Unit 1 as
    critical habitat for the dusky gopher frog.
    Alternatively, this claim is resolved on the threshold issue of the
    Landowners’ standing to raise this NEPA claim. A plaintiff bringing a claim
    under NEPA must not only have Article III standing to pursue the claim, but
    also fall within the zone of interests sought to be protected under the statute.
    See Lujan v. Nat’l Wildlife Fed’n, 
    497 U.S. 871
    , 883 (1990); Sabine River Auth.,
    40

    Cons w/ No. 
    14-31021 951 F.2d at 675
    (recognizing that the zone-of-interests test applies to
    challenges under NEPA). Other circuit courts have held that “a plaintiff who
    asserts purely economic injuries does not have standing to challenge an agency
    action under NEPA.” Nev. Land Action Ass’n v. U.S. Forest Serv., 
    8 F.3d 713
    ,
    716 (9th Cir. 1993) (citing cases from the Fourth, Eighth, Ninth, and D.C.
    Circuits). Consistent with this conclusion, we have observed in dicta that a
    “disappointed contractor” who was injured by an easement that prevented
    development opportunities would not have standing under the zone-of-
    interests test because “NEPA was not designed to protect contractors’ rights:
    it was designed to protect the environment.” Sabine River 
    Auth., 951 F.2d at 676
    . The Landowners’ asserted injuries here are similarly economic, not
    environmental: lost future development and lost property value. These
    economic injuries do not fall within the zone of interests protected by NEPA,
    and the Landowners therefore lack standing to sue to enforce NEPA’s impact-
    statement requirement.
    CONCLUSION
    For the reasons stated above, we AFFIRM the judgment of the district

    PRISCILLA R. OWEN, Circuit Judge, dissenting:
    There is a gap in the reasoning of the majority opinion that cannot be
    bridged. The area at issue is not presently “essential for the conservation of
    the [endangered] species” 1 because it plays no part in the conservation of that
    species. Its biological and physical characteristics will not support a dusky
    gopher frog population. There is no evidence of a reasonable probability (or
    any probability for that matter) that it will become “essential” to the
    conservation of the species because there is no evidence that the substantial
    alterations and maintenance necessary to transform the area into habitat
    suitable for the endangered species will, or are likely to, occur. Land that is
    not “essential” for conservation does not meet the statutory criteria for “critical
    habitat.” 2
    The majority opinion interprets the Endangered Species Act 3 to allow
    the Government to impose restrictions on private land use even though the
    land: is not occupied by the endangered species and has not been for more than
    fifty years; is not near areas inhabited by the species; cannot sustain the
    species without substantial alterations and future annual maintenance,
    neither of which the Government has the authority to effectuate, as it concedes;
    and does not play any supporting role in the existence of current habitat for
    the species. If the Endangered Species Act permitted the actions taken by the
    Government in this case, then vast portions of the United States could be
    1   16 U.S.C. § 1532(5)(A)(ii) (“The term ‘critical habitat’ for a threatened species
    means . . . specific areas outside the geographical area occupied by the species at the time it
    is listed [as endangered], upon a determination by the Secretary that such areas are essential
    for the conservation of the species.”).

    designated as “critical habitat” because it is theoretically possible, even if not
    probable, that land could be modified to sustain the introduction or
    reintroduction of an endangered species.
    The majority opinion upholds the governmental action here on nothing
    more than the Government’s hope or speculation that the landowners and
    lessors of the 1,544 acres at issue will pay for removal of the currently existing
    pine trees used in commercial timber operations and replace them with
    another tree variety suitable for dusky gopher frog habitat, and perform other
    modifications as well as future annual maintenance, that might then support
    the species if, with the landowners’ cooperation, it is reintroduced to the area.
    The language of the Endangered Species Act does not permit such an expansive
    interpretation and consequent overreach by the Government.
    Undoubtedly, the ephemeral ponds on the property at issue are
    somewhat rare. But it is undisputed that the ponds cannot themselves sustain
    a dusky gopher frog population. It is only with significant transformation and
    then, annual maintenance, each dependent on the assent and financial
    contribution of private landowners, that the area, including the ponds, might
    play a role in conservation. The Endangered Species Act does not permit the
    Government to designate an area as “critical habitat,” and therefore use that
    designation as leverage against the landowners, based on one feature of an
    area when that one feature cannot support the existence of the species and
    significant alterations to the area as a whole would be required.
    The majority opinion’s holding is unprecedented and sweeping.

    A Final Rule 4 of the United States Fish and Wildlife Service (the
    “Service”) designated 12 units of land encompassing 6,477 acres as “critical
    habitat” 5 for the dusky gopher frog. Eleven of those units, totaling 4,933 acres,
    are in four counties in Mississippi, 6 and they are not at issue in this appeal. It
    is only the owners and lessors of the twelfth unit, comprised of 1,544 acres in
    Louisiana and denominated Unit 1 by the Service, 7 that have appealed the
    designation. The dusky gopher frog species was last seen in Louisiana in 1965
    in one small pond located on Unit 1. 8
    The Service specifically found in its Final Rule that Unit 1 contains only
    one of the physical or biological features and habitat characteristics required
    to sustain the species’ life-history processes. 9         That characteristic is the
    existence of five ephemeral ponds on the Louisiana property. The Service
    acknowledged that the other necessary characteristics were lacking, finding,
    among its other conclusions, that “the surrounding uplands are poor-quality
    terrestrial habitat for dusky gopher frogs.” 10 While the Service was of the
    opinion that “[a]lthough the uplands associated with the ponds do not currently
    contain the essential physical or biological features of critical habitat, we
    believe them to be restorable with reasonable effort” 11 to permit habitation, the

    Service candidly recognized in the Final Rule that it could not undertake any
    efforts to change the current features of the land or to move frogs onto the land
    without the permission and cooperation of the owners of the land. 12 It cited no
    evidence, and there is none, that “reasonable efforts” would in fact be made to
    restore “the essential physical or biological features of critical habitat” on Unit
    1. The Service cited only its “hope” that such alterations would be taken by
    the landowners. 13
    In particular, the Service found that an open-canopied longleaf pine
    ecosystem is necessary for the habitat of this species of frog. 14 Approximately
    ninety percent of the property is currently covered with closed-canopy loblolly
    pine plantations. These trees would have to be removed or burned and then
    replaced with another tree variety to allow the establishment of the habitat
    that the Service has concluded is necessary for the breeding and sustaining of
    a dusky gopher frog population. It is undisputed that the land is subject to a
    timber lease until 2043, timber operations are ongoing, and neither the owner
    of the property nor the timber lessee is willing to permit the substantial
    alterations that the Service concluded would be necessary to restore the
    potentiality of the ponds and surrounding area as habitat for this species of
    frog.

    Review of the Service’s decisions under the Endangered Species Act is
    governed by the Administrative Procedure Act (APA). 15                       The Service’s
    designation of the land at issue as “critical habitat” was “not in accordance
    with law” and was “in excess of statutory . . . authority” within the meaning of
    the APA. 16
    The Endangered Species Act defines “critical habitat” as:
    (i) the specific areas within the geographical area occupied
    by the species, at the time it is listed in accordance with the
    provisions of section 1533 of this title, on which are found those
    physical or biological features (I) essential to the conservation of
    the species and (II) which may require special management
    considerations or protection; and
    (ii) specific areas outside the geographical area occupied by
    the species at the time it is listed in accordance with the provisions
    of section 1533 of this title, upon a determination by the Secretary
    that such areas are essential for the conservation of the species. 17
    The Final Rule reflects that “Unit 1 is not currently occupied nor was it
    occupied at the time the dusky gopher frog was listed [as an endangered
    species].” 18 Accordingly, the authority of the Service to designate this area as
    “critical habitat” is governed by subsection (ii). The statute requires that Unit

    that a claim of the Service’s “maladministration of the ESA” is not reviewable under 16
    U.S.C. § 1540(g)(1)(A) or (C) (citizen-suit provisions of the ESA) but is reviewable under the
    APA); 5 U.S.C. § 702 (“A person suffering legal wrong because of agency action, or adversely

    1 must be “essential for the conservation of the species” or else it cannot be
    designated as “critical habitat.”
    The word “essential” means more than desirable.                       Black’s Law
    Dictionary defines “essential” as “2. Of the utmost importance; basic and
    necessary. 3. Having real existence, actual.” 19 The Service’s conclusion that
    Unit 1 is “essential” for the conservation of the dusky gopher frog contravenes
    these definitions. Unit 1 is not “actual[ly]” playing any part in the conservation
    of the endangered frog species. Nor is land “basic and necessary” for the
    conservation of a species when it cannot support the existence of the
    endangered species unless the physical characteristics of the land are
    significantly modified. This is particularly the case when the Government is
    powerless to effectuate the desired transformation unless it takes (condemns)
    the property and funds these efforts.              There is no evidence that the
    modifications and maintenance necessary to transform Unit 1 into habitat will
    be undertaken by anyone.
    The Government’s, and the majority opinion’s, interpretation of
    “essential” means that virtually any part of the United States could be
    designated as “critical habitat” for any given endangered species so long as the
    property could be modified in a way that would support introduction and
    subsequent conservation of the species on it.              This is not a reasonable
    construction of § 1532(5)(A)(2).
    We are not presented with a case in which land, though unoccupied by
    an endangered species, provides elements to neighboring or downstream
    property that are essential to the survival of the species in the areas that it

    does occupy. For example, the Ninth Circuit concluded that certain areas,
    though unoccupied, were “essential” to an endangered species (the Santa Ana
    sucker, a small fish) because the designated areas were “the primary sources
    of high quality coarse sediment for the downstream occupied portions of the
    Santa Ana River,” and that “coarse sediment was essential to the sucker
    because [it] provided a spawning ground as well as a feeding ground from
    which the sucker obtained algae, insects, and detritus.” 20 In the present case,
    Unit 1 does not support, in any way, the existence of the dusky gopher frog or
    its habitat. Our analysis therefore concerns only whether the property is
    “essential for the conservation of the species” as an area that might be capable
    of occupation by the dusky gopher frog if the area were physically altered.
    The majority opinion cites the Ninth Circuit’s decision regarding the
    Santa Ana sucker as support for the majority opinion’s assertion that “[t]here
    is no habitability requirement in the text of the ESA or the implementing
    regulations. The statute requires the Service to designate ‘essential’ areas,
    without further defining ‘essential’ to mean ‘habitable.’” 21 I agree with that
    statement—up to a point. Land can be “essential” even though uninhabitable
    if it provides elements to the species’ habitat that are essential to sustain it, as
    was the case regarding the Santa Ana sucker. The majority opinion says
    instead that land can be designated as “critical habitat” even if it is not
    habitable and does not play any role in sustaining the species. The Ninth
    Circuit did not announce such a sweeping interpretation of the Endangered
    Species Act. That court held only that land not occupied by the species could

    constitute critical habitat because of the “essential” role it played in the
    survival of species as the primary source of sediment necessary for the
    spawning of the species. 22 The majority opinion has not cited any decision from
    the Supreme Court or a Court of Appeals which has construed the Endangered
    Species Act to allow designation of land that is unoccupied by the species,
    cannot be occupied by the species unless the land is significantly altered, and
    does not play any supporting role in sustaining habitat for the species.
    The meaning of the word “essential” undoubtedly vests the Service with
    significant discretion in determining if an area is “essential” to the
    conservation of a species, but there are limits to a word’s meaning and hence
    the Service’s discretion.      The Service’s interpretation of “essential for the
    conservation of the species” 23 in the present case goes beyond the boundaries
    of what “essential” can reasonably be interpreted to mean. As the Supreme
    Court has explained, “an agency’s interpretation of a statute is not entitled to
    deference when it goes beyond the meaning that the statute can bear.” 24
    In MCI Telecommunications Corp. v. AT&T Co., 23 U.S.C. § 203(a)
    required long-distance communications common carriers to file tariffs with the
    Federal Communications Commission (FCC). 25 The FCC was authorized under
    23 U.S.C. § 203(b)(2) to “‘modify any requirement made by or under the
    authority of this section either in particular instances or by general order
    applicable to special circumstances or conditions.’” 26              In a rulemaking

    proceeding, the FCC made rate tariff filings optional for all non-dominant long-
    distance carriers. 27 In subsequent proceedings, AT&T challenged the FCC’s
    statutory authority to do so, and the FCC took the position that its authority
    was derived from the “modify any requirement” provision in § 203(b). The
    Supreme Court determined that “modify” “connotes moderate change,” 28 and
    examined extensively other provisions of the Communications Act. 29            The
    Supreme Court concluded that eliminating tariff rate filings for a segment of
    the industry was “much too extensive to be considered a ‘modification.’” 30 The
    Court observed, “[w]hat we have here, in reality, is a fundamental revision of
    the statute, changing it from a scheme of rate regulation in long-distance
    common-carrier communications to a scheme of rate regulation only where
    effective competition does not exist. That may be a good idea, but it was not
    the idea Congress enacted into law in 1934.” 31 The same can be said of the
    Service’s, and the majority opinion’s, construction of the Endangered Species
    Act in the present case. It may be a good idea to permit the Service to designate
    any land as “critical habitat” if it is theoretically possible to transform land
    that is uninhabitable into an area that could become habitat. But that is not
    what Congress did.

    bear.’” 32 That court was fully cognizant of Chevron’s 33 teaching that “‘if the
    statute is silent or ambiguous with respect to the specific issue, the question
    for the court is whether the agency’s answer is based on a permissible
    construction of the statute.’” 34 In Southwestern Bell, the FCC contended that
    because the term “schedules” was not defined in the Federal Communications
    Act, the FCC could permit carriers to file ranges of rates rather than specific
    rates. 35 The District of Columbia Circuit disagreed, concluding that “[s]ection
    203(a) . . . lays out what kind of filing the statute requires: ‘schedules showing
    all charges.’ This language connotes a specific list of discernable rates; it does
    not admit the concept of ranges.” 36
    The majority opinion says that MCI Telecommunications Corp. is
    distinguishable because in that case, the agency’s interpretation of “modify”
    “flatly contradicted the definition provided by ‘virtually every dictionary [the
    Court] was aware of.’” 37 The majority opinion then observes that one definition
    of “essential” is “of the utmost importance; basic and necessary,” and concludes
    that this definition “describes well a close system of ephemeral ponds, per the
    scientific consensus that the Service relied upon.” 38                   This highlights the
    opinion’s misdirected focus and frames the question that is at the heart of this
    case.    That question is whether the Endangered Species Act permits the

    Service to designate land as critical habitat when the land has only one
    physical or biological feature that would be necessary to support a population
    of the endangered species but lacks the other primary physical or biological
    features that are also necessary for habitat. It is undisputed that ephemeral
    ponds alone cannot support a dusky gopher frog population. All likewise agree
    that Unit 1 lacks the other two primary constituent elements, which are
    upland forested nonbreeding habitat dominated by longleaf pine maintained
    by fires, and upland habitat between breeding and nonbreeding habitat with
    specific characteristics including an open canopy, native herbaceous species,
    and subservice structures.               Unit 1 is not “essential [i.e., of the utmost
    importance; basic and necessary] for the conservation of the species” 39 because
    it cannot serve as habitat unless the forests in the areas upland from the ponds
    are destroyed and the requisite vegetation (including a new forest) is planted
    and maintained. Because there is no reasonable probability that Unit 1 will
    be altered in this way, it is not “essential.”
    The Service’s implicit construction of the meaning of “essential for the
    conservation of the species” is not entitled to deference because it exceeds the
    boundaries of the latitude given to an agency in construing a statute to which
    Chevron deference is applicable. The term “essential” cannot reasonably be
    construed to encompass land that is not in fact “essential for the conservation
    of the species.” When the only possible basis for designating an area as “critical
    habitat” is its potential use as actual habitat, an area cannot be “essential for
    the conservation of the species” if it is uninhabitable by the species and there
    is no reasonable probability that it will become habitable by the species. Even

    if scientists agree that an area could be modified to sustain a species, there
    must be some basis for concluding that it is likely that the area will be so
    modified. Otherwise, the area could not and will not be used for conservation
    of the species and therefore cannot be “essential” to the conservation of the
    species.
    With great respect, at other junctures, the majority opinion misdirects
    the inquiry as to the proper meaning of “essential for the conservation of the
    species.” The opinion examines an irrelevant question in arguing that there is
    no “temporal requirement” in the text of the Endangered Species Act. For
    example, the opinion states that the Service is not required “to know when a
    protected species will be conserved as a result of a designation.” 40 Similarly,
    the majority opinion observes that the Act does not “set[] a deadline for
    achieving this ultimate conservation goal.” 41 I agree. The Act does not require
    the Service to speculate whether or when an endangered species will no longer

    habitat.” But in designating an area as “critical habitat,” the question is not
    when the species will be conserved, which is the question that the majority
    opinion raises and then dismisses. Nor is it a question of when the area will
    be essential. Rather, the pertinent inquiry is whether the area is essential for
    conservation.     An area cannot be essential for use as habitat if it is
    uninhabitable and there is no reasonable probability that it could actually be
    used for conservation.

    The majority opinion fails to discern the meaningful boundary that the
    term “essential” places on the Service in designating “critical habitat.” The
    opinion fails to appreciate the distinction between land that, because of its
    physical and biological features, cannot be used for conservation without
    significant alteration and land that is actually habitable but not occupied by
    the species. 42 The majority opinion posits that “[the Landowners’ logic] would
    also seem to allow landowners whose land is immediately habitable to block a
    critical-habitat designation merely by declaring that they will not—now or
    ever—permit the reintroduction of the species to their land.” 43 The fact that a
    landowner is unwilling to permit the reintroduction of a species does not have
    a bearing on whether the physical and biological features of the land make it
    suitable as habitat. Land that is habitable but unoccupied by the species may
    be “essential” if the areas that a species currently occupies are inadequate for
    its survival. Even if the landowner asserts that it will not allow introduction
    of the species, the Service may designate the land as “critical habitat” because
    it is in fact habitable, and the consultation and permitting provisions of the Act
    may be used to attempt to persuade the owner to not destroy the features that
    make the area habitable and to allow the species to be reintroduced. However,
    when land would have to be significantly modified to either serve as habitat or
    to serve as a source of something necessary to another area that is habitat
    (such as the sediment in the Santa Ana sucker case), then whether there is a
    probability that the land will be so modified must be part of the equation of
    whether the area is “essential.” Unless the land is modified, it is useless to the

    species and therefore cannot be “essential.” Under such circumstances, the
    Service cannot designate land as “critical habitat” unless there is an objective
    basis for concluding that modifications will occur because otherwise, the land
    cannot play a role in the species’ survival.
    The majority opinion rejects the logical limits of the word “essential” in
    concluding that requiring either actual use for conservation or a reasonable
    probability of use for conservation to satisfy the “essential for the conservation
    of the species” requirement in the statute would be reliant on the subjective
    intentions of landowners. 44 Whether there is a reasonable probability that
    land will be modified so that it is suitable as habitat is an objective inquiry
    that would consider many factors. Those factors might well (and in most
    instances probably would) include economic considerations such as the values
    of various uses of the land.         The inquiry would be whether a reasonable
    landowner would be likely to undertake the necessary modifications. In some
    cases, a landowner might have entered into an agreement to modify land so
    that it may be used as habitat, and in such a case, there would be nothing
    “subjective” in concluding that it is reasonably probable that the land will
    actually be used as habitat and therefore “essential” for the conservation of the
    species.
    The majority opinion’s interpretation of the Endangered Species Act is
    illogical, inconsistent, and depends entirely on adding words to the Act that
    are not there. Those words are “a critical feature.” 45 On one hand, the majority

    opinion says that “we find it hard to see how the Service would be able to
    satisfactorily explain” the designation of an empty field as habitat.” 46 Yet, in
    the next paragraph, the opinion says that because the designation in this case
    “was based on the scientific expertise of the agency’s biologists and outside
    gopher frog specialists,” this court is required to affirm the “critical habitat”
    designation. 47 It is easily conceivable that “the best scientific data available” 48
    would lead scientists to conclude that an empty field that is not currently
    habitable could be altered to become habitat for an endangered species.
    Apparently recognizing that unless cabined in some way, the majority
    opinion’s holding would give the Service unfettered discretion to designate land
    as “critical habitat” so long as scientists agree that uninhabitable land can be
    transformed into habitat, the majority opinion asserts that at least one
    “physical or biological feature[] . . . essential to the conservation of the
    species” 49 must be present to permit the Service to declare land that is
    uninhabitable by the species to be “critical habitat.” It must be emphasized
    that this is the linchpin to the majority’s holding. When the only potential use
    of an area for conservation is use as habitat, the Service cannot designate
    uninhabitable land as “critical habitat,” the majority opinion concedes, even if

    opinion says, if, as in the present case, there is at least one physical or
    biological feature essential to the conservation of the species (also denominated
    by the Service as a primary constituent element, as explained in footnote 12 of
    the majority opinion), the presence of one, and only one, of three indispensable
    physical or biological features required for habitat is sufficient to allow the
    Service to designate uninhabitable land as “critical habitat.” The opinion says:
    Here, the Service confirmed through peer review and two rounds
    of notice and comment a scientific consensus as to the presence and
    rarity of a critical (and difficult to reproduce) feature—the
    ephemeral ponds—which justified its finding that Unit 1 was
    essential for the conservation of the dusky gopher frog. 51
    This re-writes the Endangered Species Act. It permits the Service to
    designate an area as “critical habitat” if it has “a critical feature” even though
    the area is uninhabitable and does not play a supporting role to an area that
    is habitat. Neither the words “a critical feature” nor such a concept appear in
    the Act. The touchstone chosen by Congress was “essential.” The existence of
    a single, even if rare, physical characteristic does not render an area “essential”
    when the area cannot support the species because of the lack of other necessary
    physical characteristics.
    The       majority     opinion’s   reasoning   also   suffers   from   internal
    inconsistency. The opinion asserts that, unlike land that is occupied by the
    species, there is no requirement under the Endangered Species Act that

    features]” 52 that are “essential to the conservation of the species” 53 before the
    Secretary may designate it as critical habitat. 54 This clearly implies, if not
    states, that the Secretary can designate unoccupied land as critical habitat
    even if the land has no primary constituent physical or biological element (to
    use the Service’s vernacular) essential to the conservation of the species. 55 If
    land can be “essential for the conservation of the species” even when it has no
    physical or biological features essential to the conservation of the species, then
    what, exactly, is it about the land that permits the Service to find it “essential”?
    The majority opinion does not answer this question. Instead, a few pages after
    making the assertion that unoccupied land can be designated even when it has
    no features essential to the conservation of the species, the opinion rejects this
    proposition. 56    The majority opinion says (in attempting to counter the
    argument that its holding would permit the Service to designate an empty field
    as critical habitat even though not habitable) that it would be arbitrary and
    capricious for the Service to find an empty field “essential” if there were other
    similar fields. 57 The opinion concludes that if land that is uninhabitable could
    be modified to become habitat, the Service could not deem the land “essential”
    if there were other parcels of land similar to it that could also be modified:
    We fail to see how the Service would be able to similarly justify as
    rational an essentiality finding as to arbitrarily chosen land. In
    contrast, the dissent, similar to the Landowners, contends that

    would lead scientists to conclude that an empty field that is not
    currently habitable could be altered to become habitat for an
    endangered species.” Even assuming that to be true, it does not
    follow that scientists or the Service would or could then reasonably
    call an empty field essential for the conservation of a species. If
    the field in question were no different than any other empty field,
    what would make it essential? Presumably, if the field could be
    modified into suitable habitat, so could any of the one hundred or
    one thousand other similar fields. If the fields are fungible, it
    would be arbitrary for the Service to label any single one
    “essential” to the conservation of a species. It is only by
    overlooking this point that the dissent can maintain that our
    approval of the Service’s reading of “essential” will “mean[] that
    virtually any part of the United States could be designated as
    ‘critical habitat’ for any given endangered species so long as the
    property could be modified in a way that would support
    introduction and subsequent conservation of the species on it.” 58
    I have difficulty with this reasoning. There is undeniably a textual
    difference in the Endangered Species Act between the sections dealing with an
    area occupied by the species and an area unoccupied by that species.                If
    Congress did in fact intend to authorize the Service to designate unoccupied
    land as “critical habitat” even if it had no “physical or biological features . . .
    essential to the conservation of the species” but could be modified to become
    habitat, then it would not seem to be arbitrary or capricious for the Service to
    designate any particular parcel of land as critical habitat, even if there were
    other similar lands.          The intent of Congress would be that land can be
    designated if the survival of the species depends on creating habitat for it. If
    this were in fact the intent of Congress, it would not be reasonable to say that
    because there is an abundance of land that could be modified to save the

    species, none of it can be designated. But the majority opinion is unwilling to
    construe the Act in such a manner, because, as the opinion explains, Congress
    used the word “essential” as a meaningful limit on the authority of the Service
    to designate “critical habitat.” The opinion reasons, “[i]f the fields [that could
    be modified] are fungible, it would be arbitrary for the Service to label any
    single one ‘essential’ to the conservation of the species.” 59 Acknowledging that
    land lacking any features necessary for habitat cannot be “essential” to the
    conservation of the species, the opinion finds it necessary to construct a
    tortured interpretation of the Act to affirm what the Service has done in this
    case. That interpretation is as follows: land with no physical or biological
    features essential to the conservation of the species that is not occupied by the
    species but could be modified to become habitable can be deemed “essential”
    and designated as critical habitat, but only if there are virtually no other tracts
    similar to it, or land that is uninhabitable by the species but that has at least
    one physical or biological feature can be designated as critical habitat if the
    land can be modified to create all the other physical or biological features
    necessary to transform it into habitat for the species. I do not think that the
    word “essential” can bear the weight that the majority opinion places upon it
    in arriving at its interpretation of the Act.
    The majority opinion strenuously denies that its holding allows the
    Service to “designate any land as critical habitat whenever it contains a single
    one of the ‘physical or biological features’ essential to the conservation of the
    species at issue.” 60 But the opinion’s ensuing explanation illustrates that is

    precisely the import of its holding: “if the ponds are essential, then Unit 1,
    which contains the ponds, is essential for the conservation of the dusky gopher
    frog.” 61 The Service itself found, based on scientific data, that the ponds are
    only one of three “primary constituent elements” that are “essential to the
    conservation of the species.” 62 The other two primary constituent elements are
    not present on Unit 1 and would require substantial modification of Unit 1 to
    create them. 63
    The Service’s construction of the Endangered Species Act is not entitled
    to any deference because it goes beyond what the meaning of “essential” can
    encompass. The Service’s construction of the Act is impermissible, and the
    Service exceeded its statutory authority.

    The majority opinion quotes a Supreme Court decision, which
    says: “[w]hen examining this kind of scientific determination, as opposed to
    simple findings of fact, a reviewing court must generally be at its most
    deferential.” 64 However, the panel’s majority opinion does not identify any
    finding by the Service as being “this kind of scientific determination.” Instead,
    the opinion appears to address the proper interpretation of “essential for the
    conservation of the species,” as applied to the point of contention in this case,
    as a question of law based on the words Congress chose.

    The fact that scientific evidence was a part of the proceedings leading to
    the Final Rule 65 does not mean that all determinations in the Final Rule are
    subject to deference by a reviewing court. No one disputes that reputable
    scientists made valid determinations in the administrative proceedings
    undertaken by the Service. However, the scientific evidence and conclusions
    have no bearing on the issue of statutory construction about which the parties
    in this case disagree: Did Congress intend to permit the designation of land as
    “critical habitat” when the land is not occupied by an endangered species and
    would have to be substantially modified then periodically maintained in order
    to be used as habitat, and when there is no indication that the land will in fact
    be modified or maintained in such a manner?
    IV
    The phrase “essential for the conservation of the species” requires more
    than a theoretical possibility that an area designated as “critical habitat” will
    be transformed such that its physical characteristics are essential to the
    conservation of the species. There is no evidence that it is probable that Unit
    1 will be physically modified in the manner that the scientists uniformly agree
    would be necessary to sustain a dusky gopher frog population. The conclusion
    by the Service that Unit 1 is “essential for the conservation of the species” is
    therefore not supported by substantial evidence, and the designation of Unit 1
    as “critical habitat” should be vacated under the APA.
    The Service recognized in the Final Rule that under the Endangered
    Species Act and regulations implementing it, the Service is “required to
    65See 16 U.S.C. § 1533(b)(2) (“The Secretary shall designate critical habitat, and make

    identify the physical or biological features essential to the conservation of the
    dusky gopher frog in areas occupied at the time of listing, focusing on the
    features’ primary constituent elements.” 66 The Service explained that “[w]e
    consider primary constituent elements to be the elements of physical or
    biological features that, when laid out in the appropriate quantity and spatial
    arrangement to provide for a species’ life-history processes, are essential to the
    conservation of the species.” 67 The Service identified three primary constituent
    elements, briefly summarized as ephemeral wetland habitat with an open
    canopy (with certain specific characteristics), upland forested nonbreeding
    habitat dominated by longleaf pine maintained by fires frequent enough to
    support an open canopy and abundant herbaceous ground cover, and upland
    habitat between breeding and nonbreeding habitat that is characterized by an
    open canopy, abundant native herbaceous species, and a subsurface structure
    that provides shelter for dusky gopher frogs during seasonal movements. 68
    The other eleven units designated in the Final Rule had all three
    constituent elements. 69 However, the Service found that Unit 1 has only one
    of the three primary constituent elements detailed in the Final Rule—the
    ephemeral ponds. 70 Isolated wetlands, like the ephemeral ponds that exist on
    Unit 1, are necessary to sustain a population of the species as a breeding
    ground. 71 But frogs do not spend most of their lives breeding in ponds, and the
    existence of the ponds will not alone provide the necessary habitat. “Both

    forested uplands and isolated wetlands . . . are needed to provide space for

    found that dusky gopher frogs “spend most of their lives underground in
    forested habitat consisting of fire-maintained, open-canopied, pine woodlands
    historically dominated by longleaf pine.” 73 Unit 1 is covered with a closed-
    canopy forest of loblolly pines.
    The Service also identified the alterations and special management that
    would be required within the areas designated as critical habit, including Unit
    1, to sustain a dusky gopher frog population. 74 The Service found with regard
    to Unit 1 that “[a]lthough the uplands associated with the ponds do not
    currently contain the essential physical or biological features of critical
    habitat, we believe them to be restorable with reasonable effort.” 75                   This
    finding is insufficient to sustain the conclusion that Unit 1 is “essential for the
    conservation of the species” for at least two reasons. First, finding that the
    uplands are “restorable” is not a finding that the areas will be “restored.”

    activities that could ameliorate these threats include (but are not limited
    to): (1) Maintaining critical habitat areas as forested pine habitat (preferably
    longleaf pine); (2) conducting forestry management using prescribed burning,
    avoiding the use of beds when planting trees, and reducing planting densities
    to create or maintain an open canopied forest with abundant herbaceous
    ground cover; (3) maintaining forest underground structure such as gopher
    tortoise burrows, small mammal burrows, and stump holes; (4) and protecting
    ephemeral wetland breeding sites from chemical and physical changes to the

    Unless the uplands are restored, they cannot be and are not essential for the
    conservation of the frog. Second, the Service does not explain who will expend
    the “reasonable effort” necessary to restore the uplands.           In sum, the
    designation of Unit 1 as critical habitat is not supported by substantial
    evidence because there is no evidence that Unit 1 will be modified in such a
    way that it can serve as habitat for the frog.
    In fact, the Service itself concluded that it is entirely speculative as to
    whether Unit 1 will be transformed from its current use for commercial timber
    operations into dusky gopher frog habitat by removing the loblolly pines and
    replacing them with longleaf pines, and by the other activities necessary to
    create frog habitat. The Service was required by the Endangered Species Act
    to assess the economic impact of designating critical habitat. 76 The Service
    recognized that as to Unit 1, the economic impact depended on the extent to
    which it might be developed, 77 and accordingly, whether section 7 consultation
    would be required because of a federal nexus. 78 Section 7 consultation would
    provide at least some potential that the owners of the land would be required
    to take measures to create habitat for the dusky gopher frog in order to obtain
    federal permits that would allow development. But the Service specifically
    found that “considerable uncertainty exists regarding the likelihood of a
    Federal nexus for development activities” on Unit 1, 79 and that only the
    “potential exists for the Service to recommend conservation measures if
    consultation were to occur.” 80 This does not constitute substantial, or even any,

    evidence that Unit 1 is now or will become suitable habitat for the dusky
    gopher frog, which is the only basis on which the Service has ever posited that
    Unit 1 is “essential for the conservation of the species.” 81 (As discussed above,
    the Service has never contended that Unit 1 is essential because of support
    that it provides to another area that is occupied by the frog.)
    The Service described three different scenarios to assess the potential
    economic impact of the Final Rule. 82 In the first scenario, “no conservation
    measures are implemented for the species.” 83              The Service reasoned that
    development on Unit 1 might avoid any federal nexus and therefore no
    consultation would be required, and no conservation of the species would occur.
    The Service therefore expressly recognized that Unit 1 may never play any role
    in the “conservation of the species.”
    In the Service’s second scenario, the Service assumes that development
    is sought by the owners, 84 section 7 consultation occurs that results in
    81 16 U.S.C. § 1532(5)(A)(ii).

    (emphasis added). The Service explained:
    Under scenario 1, development occurring in Unit 1 avoids impacts to
    jurisdictional wetlands and as such, there is no Federal nexus (no Federal
    permit is required) triggering section 7 consultation regarding dusky gopher
    frog critical habitat. Absent consultation, no conservation measures are
    implemented for the species, and critical habitat designation of Unit 1 does not
    result in any incremental economic impact.

    According to scenarios 2 and 3, the vast majority of the incremental
    impacts would stem from the lost development value of land in Unit 1. Under
    scenarios 2 and 3, less than one percent of the incremental impacts stem from
    the administrative costs of future section 7 consultations. Under scenario 2,
    the analysis assumes the proposed development of Unit 1 requires a Section
    404 permit from the Corps due to the presence of jurisdictional wetlands. The
    development would therefore be subject to section 7 consultation considering
    critical habitat for the dusky gopher frog. This scenario further assumes that

    development on 40% of Unit 1, and the remaining 60% is managed as dusky
    gopher frog habitat. 85 (The Service estimates that the landowners would suffer
    a loss of $20.4 million due to the loss of the option to develop 60% of the area.) 86
    This is the only scenario, in the entirety of the Final Rule, that explains how,
    at least theoretically, Unit 1’s landscape would be altered so that it could be
    used as dusky gopher frog habitat. But the Service made no findings that this
    scenario was likely or probable.
    Under Scenario 3, the Service assumes that the owners desire to develop
    Unit 1, section 7 consultation occurs, but no development is permitted on Unit
    1 by the Government “due to the importance of the unit in the conservation
    and recovery of the species. 87 (The Service estimates that the loss of the option
    to develop 100% of Unit 1 would result in a loss of $33.9 million to the
    the Service works with the landowner to establish conservation areas for the
    dusky gopher frog within the unit. The Service anticipates that approximately
    40 percent of the unit may be developed and 60 percent is managed for dusky
    gopher frog conservation and recovery. According to this scenario, present
    value incremental impacts of critical habitat designation due to the lost option
    for developing 60 percent of Unit 1 lands are $20.4 million. Total present value
    incremental impacts of critical habitat designation across all units are
    therefore $20.5 million ($1.93 million in annualized impacts), applying a 7
    percent discount rate.
    Scenario 3 again assumes that the proposed development of Unit 1
    requires a Section 404 permit and therefore is subject to section 7 consultation.
    This scenario further assumes that, due to the importance of the unit in the
    conservation and recovery of the species, the Service recommends that no
    development occur within the unit. According to this scenario, present value
    impacts of the lost option for development in 100 percent of the unit are $33.9
    million.     Total present value incremental impacts of critical habitat
    designation across all units are therefore $34.0 million ($3.21 million in
    annualized impacts), applying a 7 percent discount rate.

    owners.) 88 Significantly, the Service does not posit that any of Unit 1 would
    actually be used as dusky gopher frog habitat under Scenario 3, in spite of its
    alleged “importance” to conservation. Undoubtedly, that is because if the
    federal government would not permit the landowners to develop any part of
    Unit 1, why would the owners undertake to modify Unit 1 so that it could be
    used as frog habitat? The Government has no plans to pay for the creation of
    habitat on Unit 1. Habitat will only be created, and therefore conservation will
    only occur, if the owners decide to modify their property. The only evidence in
    the record is that the owners do not plan to do so and there is no evidence that
    the economic or other considerations would lead a reasonable landowner to
    create frog habitat on Unit 1.
    Scenario 3 shows, in the starkest of terms, why the Service’s position
    that Unit 1 is “essential for the conservation of the species” is illogical on its
    face. Even if the Government does not allow any development on Unit 1
    because of the existence of the ephemeral ponds, the Government is aware that
    Unit 1 cannot be used for the conservation of the dusky gopher frog because
    someone or some entity would have to significantly modify Unit 1 to make it
    suitable for frog habitat.       Unsuitable habitat is not essential for the
    conservation of the species.

    I would vacate the Final Rule’s designation of Unit 1 as critical habitat,
    and I therefore dissent.
