    SUMMARY **
    Environmental Law
    The panel affirmed the district court’s summary
    judgment in favor of the U.S. Fish and Wildlife Service in
    an action brought by an environmental group challenging the
    Service’s “barred owl removal experiment,” which was
    designed to protect the northern spotted owl, a threatened
    species under the Endangered Species Act (“ESA”).
    Barred owls have encroached on the spotted owl’s
    habitat. The barred owl removal experiment is a proposed
    lethal removal of barred owls from certain areas to measure
    their environmental and demographic effect on northern
    spotted owls. To complete the experiment, the Service
    issued permits and entered into Safe Harbor Agreements
    with four non-federal landowners within the Oregon coast
    ranges study area.
    Plaintiff alleged that the ESA prohibited the government
    from taking action that may incidentally harm spotted owls
    or their habitat unless it provided a “net conservation
    benefit,” and the barred owl removal experiment will not
    yield a net conservation benefit because it does not likely
    lead to the recovery of the spotted owl population or its
    habitat.
    Affirming the district court, the panel held that the barred
    owl removal experiment will produce a “net conservation
    benefit” under the ESA’s implementing regulations because

    it allowed the agency to obtain critical information to craft a
    policy to protect threatened or endangered species. The
    panel also held that the Service reasonably described
    baseline conditions/“resident” owl survey data. In addition,
    the panel held that the Service adequately analyzed the small
    portion of critical habitat affected by the Oregon permit/Safe
    Harbor Agreements.
    The panel held that the Service complied with the
    National Environmental Policy Act (“NEPA”), and did not
    have to conduct a supplemental environmental impact
    statement under NEPA because it had adequately
    contemplated this experiment in its earlier analysis. In
    addition, the permits and the experiment need not be
    analyzed in a single environmental impact statement because
    they were not “connected actions.”

    OPINION
    LEE, Circuit Judge:
    This case is a tale of two owls. For the northern spotted
    owl, it has been the worst of times: It remains a threatened
    species, and its population continues to dwindle in the
    Pacific Northwest and Northern California. But it has been
    the best of times for the barred owl: Its abundant population
    burgeoning, the barred owl has expanded westward and
    encroached on the spotted owl’s habitat. And barred owls
    have even been spotted attacking their brethren bird.
    Trying to usher in a spring of hope for the northern
    spotted owls, the United States Fish and Wildlife Service
    (FWS) introduced a “barred owl removal experiment.” It
    proposed lethally removing barred owls from certain areas
    to measure their environmental and demographic effect on
    the northern spotted owls. Friends of Animals (“Friends”),
    an environmental group, sued the FWS, claiming that this
    experiment violates the Endangered Species Act (ESA) and
    the National Environmental Policy Act (NEPA). Friends
    mainly argues that the ESA prohibits the government from
    taking action that may incidentally harm spotted owls or
    their habitat unless it provided a “net conservation benefit.”
    On top of harming some spotted owls as scientists enter their
    habitat, the experiment will not yield a “net conservation
    benefit” because it does not directly lead to the recovery of
    the spotted owl population or its habitat, according to
    Friends.
    We affirm the district court’s grant of summary
    judgment for FWS. We hold that this experiment will
    produce a “net conservation benefit” under the plain
    language of the ESA’s implementing regulations because it
    allows the agency to obtain critical information to craft a
    policy to protect threatened or endangered species. We also
    FRIENDS OF ANIMALS V. USFWS                    5
    hold that FWS did not have to conduct a supplemental
    environmental impact statement under NEPA because it had
    adequately contemplated this experiment in its earlier
    analysis.
    BACKGROUND
    I. Background
    a. The barred owl threatens the northern spotted
    owl.
    The northern spotted owl is one of three subspecies of
    spotted owls (Northern, California, and Mexican). The
    species generally lives in mature and old-growth forests
    around southwest British Columbia through the Cascade
    Mountains and coastal ranges in Washington, Oregon, and
    Northern California. Since 1990, FWS has listed the
    northern spotted owl as a threatened species under the ESA.
    The barred owl, in contrast, is an abundant species native
    to eastern North America. Over the past century, the barred
    owl has moved west, expanding its range across the
    continent to the west coast. And in the process, the barred
    owl has encroached on the northern spotted owl’s range,
    becoming an invasive species. The barred owl’s and spotted
    owl’s ranges now completely overlap, and the two species’
    food needs and habitats share significant similarities as well.
    In its most recent 2011 Recovery Plan for the northern
    spotted owl, FWS stated that “[s]trong evidence indicates
    that barred owls negatively affect spotted owls and their
    populations” by displacing spotted owls from their habitat
    and reducing spotted owl survival and reproduction. Barred
    owls have also sometimes attacked the northern spotted owl.
    6             FRIENDS OF ANIMALS V. USFWS
    b. FWS designs a barred owl removal experiment.
    FWS identified “barred owl management” as one of the
    four basic steps to protect the northern spotted owl. The
    2011 Recovery Plan noted that while evidence suggests that
    “barred owls compete with spotted owls for nesting sites,
    roosting sites, and food, and possibly predate spotted owls,”
    there are still “substantial information gaps.” To fill these
    informational gaps, the Recovery Plan called for FWS to
    “[d]esign and implement large-scale control experiments to
    assess the effects of barred owl removal on spotted owl site
    occupancy, reproduction, and survival.”
    FWS then issued a Record of Decision in 2013
    authorizing the lethal barred owl removal experiment. FWS
    expected the experiment to provide “needed information”
    such as “the effects of barred owls on spotted owl vital rates
    of occupancy, survival, reproduction, and population trend”;
    the “feasibility of removing barred owls from an area”; the
    “level of effort required to maintain reduced barred owl
    population levels”; the “cost of barred owl removal”; and the
    overall utility of barred owl removal for “management of
    barred owls.”
    FWS’ experiment designated four study areas spread
    across the northern spotted owl’s range. Relevant here is the
    Oregon Coast Ranges study area, which covers just over
    500,000 acres. Within the study area, FWS designated
    “treatment areas” from which about 3,600 barred owls
    would be removed. FWS expected removal to be completed
    in four years, though the overall experiment, including
    conducting surveys and gathering data, could last up to ten
    years.
    FWS also issued an Environmental Impact Statement
    (EIS) in 2013 for the experiment, as required by NEPA.
    FRIENDS OF ANIMALS V. USFWS                              7
    NEPA is “a procedural statute intended to ensure Federal
    agencies consider the environmental impacts of their actions
    in the decision-making process.” 
    40 C.F.R. § 1500.1
    . 1 For
    major actions that will significantly affect the environment,
    NEPA requires federal agencies to inform the public of their
    analysis in an EIS. See 
    42 U.S.C. § 4332
    (C); 
    40 C.F.R. § 1502.4
    (a). Additionally, an agency may need to issue a
    supplemental       environmental        impact      statement
    (Supplemental EIS) to augment a prior EIS if the agency
    makes “substantial changes” to the action, or “significant
    new circumstances or information” arises. 
    40 C.F.R. §1502.9
    (d)(1). 2
    The EIS for the barred owl removal experiment
    concluded that it would have a negligible effect on the barred
    owl population, given the species’ abundance. The EIS also
    acknowledged that the northern spotted owl could
    experience “minor and short-term negative effects” because
    of the intrusions by scientists into its habitat. But the main
    anticipated effect would be a potential “positive change in
    1
    In the time between the filing of the lawsuit and our decision today,
    NEPA’s regulations were updated. See Update to the Regulations
    Implementing the Procedural Provisions of the National Environmental
    Policy Act, 
    85 Fed. Reg. 43,304
     (July 16, 2020) (to be codified at 
    40 C.F.R. §§ 1500
    –1508, 1515–1518). We cite the current version of the
    regulations throughout our decision. The old and new versions of the
    cited regulations are substantively the same.

    If the proposed action on its face does not appear to have a
    significant impact, an agency may prepare a less-intensive
    environmental assessment (EA) to determine whether the action’s effects
    would be significant. See 
    40 C.F.R. § 1501.5
    (a)–(c). If the agency
    concludes in its EA that the proposed action will not significantly affect
    the human environment, the agency may issue a “finding of no
    significant impact” (FONSI) rather than produce a full-scale EIS.

    spotted owl demographic performance” because of
    decreased competition from the barred owl. More broadly,
    the major benefit of the experiment would be obtaining data
    necessary to craft long-term recovery strategies for the
    northern spotted owl.
    c. Endangered Species Act bars actions that harm
    threatened or endangered species and their
    habitats unless they provide a “net conservation
    benefit.”
    Before FWS could begin this experiment, it had to
    comply with the ESA’s many requirements. Section 7(a)(2)
    of the ESA requires each federal agency to consult an expert
    wildlife agency to ensure “that any action authorized,
    funded, or carried out . . . is not likely to jeopardize the
    continued existence of any endangered species or threatened
    species or result in the destruction or adverse modification”
    of the critical habitat. 
    16 U.S.C. § 1536
    (a)(2).
    Section 7 and its implementing regulations detail the
    consultation process for determining the biological impacts
    of a proposed action, leading to a Biological Opinion
    (BiOp). 
    Id.
     § 1536(b)(3)(A); 
    50 C.F.R. § 402.14
    (h). In the
    Biological Opinion, the expert agency (here, FWS) renders
    its opinion whether the proposed action will likely
    “jeopardize the continued existence of a listed species or
    result in the destruction or adverse modification of critical
    habitat.” 
    50 C.F.R. § 402.14
    (g)(4).
    Along with requiring cross-agency consultation, the
    ESA broadly prohibits the “take” of any endangered or
    threatened species in the United States. 
    16 U.S.C. § 1538
    .
    “Take” means “to harass, harm, pursue, hunt, shoot, wound,
    kill, trap, capture, or collect, or to attempt to engage in any
    such conduct.” 
    Id.
     § 1532(19). The ESA’s implementing
    FRIENDS OF ANIMALS V. USFWS                   9
    regulations also define “harm” in the definition of “take” to
    include “significant habitat modification or degradation
    where it actually kills or injures wildlife by significantly
    impairing essential behavioral patterns, including breeding,
    feeding or sheltering.” 
    50 C.F.R. § 17.3
    (c)(3).
    Despite this general prohibition on take, the ESA
    provides a few exceptions. Relevant here, FWS may issue
    “Enhancement of Survival Permits” that authorize take “for
    scientific purposes or to enhance the propagation or survival
    of the affected species . . . .” 
    16 U.S.C. § 1539
    (a)(1)(A).
    FWS may issue these permits and enter into corresponding
    Safe Harbor Agreements with non-federal landowners
    whose lands that the agency seeks to use for conservation
    efforts. See 
    50 C.F.R. § 17.32
    (c)(1). The Safe Harbor
    Agreements set the terms of the permits and try to
    incentivize non-federal property owners to voluntarily
    undertake conservation activities on their property. 
    Id.
     In
    exchange, FWS assures property owners that it will “not
    require additional or different management activities” and
    will allow the property to return to its previous condition at
    the agreement’s conclusion. 
    Id.
     § 17.32(c)(5).
    To issue a permit, FWS must find that:
    “The implementation of the terms of the Safe
    Harbor Agreement is reasonably expected to
    provide a net conservation benefit to the
    affected listed species by contributing to the
    recovery of [the] listed species included in
    the permit, and the Safe Harbor Agreement
    otherwise complies with the Safe Harbor
    policy available from the Service.”
    Id. § 17.32(c)(2) (emphasis added). In 1999, FWS issued its
    Safe Harbor Policy that fleshed out the requirements for
    10              FRIENDS OF ANIMALS V. USFWS
    issuing permits. See Announcement of Final Safe Harbor
    Policy, 
    64 Fed. Reg. 32,717
     (June 17, 1999) (the Policy).
    d. FWS issues Enhancement of Survival Permits
    and enters into Safe Harbor Agreements with
    four non-federal landowners.
    The Oregon Coast Ranges study area is a checkerboard
    of federal, state, and private land. To create contiguous areas
    for the experiment, FWS sought cooperation from non-
    federal landowners to gain access to their lands. Though not
    strictly necessary to complete the experiment, such access
    would help FWS complete the experiment in the most
    efficient and complete manner. Failure to gain such access
    could reduce the ability to detect changes in the spotted owl
    population caused by barred owl removal.
    To that end, FWS issued permits and entered into Safe
    Harbor Agreements with four non-federal landowners
    within the Oregon Coast Ranges study area: Roseburg
    Resource Company (Roseburg), Weyerhaeuser Company
    (Weyerhaeuser), Oxbow Timber I, LLC (Oxbow), and the
    Oregon Department of Forestry (Oregon). 3
    Each permittee agreed to allow FWS to access their
    property and roads to remove barred owls and agreed to
    conduct or support spotted owl surveys on their lands. In
    exchange, the permittees may keep harvesting timber on
    their property in areas where no northern spotted owls
    resided when the parties entered into the Safe Harbor
    Agreements (“non-baseline sites”) without incurring
    3
    After FWS issued the permits, Roseburg acquired Oxbow. Because
    of this acquisition, there are now only three permits for the Oregon Coast
    Ranges study area that are being challenged (Roseburg-Oxbow,
    Weyerhaeuser, and Oregon).
    FRIENDS OF ANIMALS V. USFWS                  11
    liability for incidentally taking any spotted owls that later
    reoccupy those locations. The permittees, however, receive
    no liability protection for any incidental take in areas where
    the owls already resided (“baseline sites”).
    FWS used survey data to designate any site in which a
    “resident” northern spotted owl had been detected in the
    previous three to five years as a baseline site. Thus, the
    permits authorized incidental take only in non-baseline sites
    (i.e., areas where no “resident” northern spotted owls have
    been observed in the past three to five years). And even in
    those non-baseline sites, the permits restricted the land
    during nesting and rearing season.
    As required by the ESA’s implementing regulations,
    FWS determined that each permit was “reasonably expected
    to provide a net conservation benefit” to the northern spotted
    owl. See 
    50 C.F.R. § 17.32
    (c)(2). Although FWS
    acknowledged that there was potential for “take of spotted
    owls on the temporarily reoccupied” non-baseline sites,
    FWS concluded such take would be “more than offset by the
    value of the information gained from the Experiment and
    potential contribution to long-term barred owl management
    strategy.”
    e. FWS prepares Biological Opinions and EAs to
    comply with the ESA and NEPA, respectively.
    As required by the ESA, FWS issued a series of
    Biological Opinions simultaneously with the permits and
    Safe Harbor Agreements.          The Biological Opinions
    determined that the Roseburg, Oxbow, and Weyerhaeuser
    permits would neither jeopardize the northern spotted owl
    nor adversely modify its critical habitat. Given each
    permit’s small effect on spotted owl habitat, FWS concluded
    that the potential harm caused by the experiment would
    12            FRIENDS OF ANIMALS V. USFWS
    likely be offset by the information gained if the experiment
    succeeded.
    FWS’ analysis differed slightly for the Oregon permit
    because of its potential effect on a small portion of critical
    habitat. In total, the Oregon permit authorized up to 3,345
    acres of critical habitat loss. This represented less than 0.04
    percent of total range-wide spotted owl critical habitat. FWS
    still believed that such habitat destruction was justified
    because it would aid the barred owl removal experiment.
    FWS thus concluded that the Oregon permit was unlikely to
    jeopardize the northern spotted owl or its critical habitat.
    And as required by NEPA, FWS also prepared an
    Environmental Assessment for each permit.               Each
    Environmental Assessment made a Finding of No
    Significant Impact, concluding that the permit is “not likely
    to have a significant impact on the spotted owl.” The permits
    only authorized incidental take in non-baseline sites that do
    not currently have spotted owls and are unlikely to be
    recolonized without barred owl removal. Thus, northern
    spotted owls would be taken only if the experiment
    facilitated spotted owl recolonization in previously
    unoccupied areas.
    f. Friends sues FWS, alleging violations of the ESA
    and NEPA.
    In June 2017, Friends sued FWS, challenging the
    issuance of the Enhancement of Survival permits and Safe
    Harbor Agreements in the Oregon Coast Ranges and
    Klamath study areas. The district court held that Friends
    lacked standing to bring either claim. See Friends of
    Animals v. Sheehan, 
    2018 WL 6531676
    , *5 (D. Or. Dec. 11,
    2018). This court reversed in part, holding that Friends had
    standing to challenge permits issued in the Oregon Coast
    FRIENDS OF ANIMALS V. USFWS                13
    Ranges, but not the Klamath, study area. Friends of Animals
    v. U.S. Fish & Wildlife Serv., 789 F. App’x 599, 600–01 (9th
    Cir. 2020).
    On remand, the district court considered the merits and
    granted summary judgment for FWS. Friends of Animals v.
    Sheehan, 
    2021 WL 150011
    , *1 (D. Or. Jan. 15, 2021).
    Friends alleged FWS violated the ESA by “(1) issuing a
    permit that fails to achieve a ‘net conservation benefit,’ (2)
    failing to use the best biological and habitat information in
    forming baseline conditions, and (3) failing to analyze the
    SHA’s effect on critical habitat.” 
    Id. at *3
    . Additionally,
    Friends claimed FWS violated NEPA because it (1) failed to
    conduct a Supplemental EIS after issuing the permits, and
    (2) failed to discuss the experiment and permits in a single
    EIS as required for “connected actions.” 
    Id. at *13
    .
    For the first ESA claim, the district court determined that
    the regulation specifying that a Safe Harbor Agreement
    should be “reasonably expected to provide a net
    conservation benefit,” see 
    50 C.F.R. § 17.32
    (c)(2), was
    ambiguous. 
    Id. at *3
    . Because the district court found that
    the Safe Harbor Policy referenced by § 17.32 did not carry
    the force of law, it held that the Safe Harbor Policy—which
    elaborates on the meaning of “net conservation benefit”—
    could not be used to resolve the ambiguity. Id. at *5.
    Because § 17.32 was ambiguous, the district court applied
    Auer 4 deference to FWS’ interpretation that “information”
    may constitute a “net conservation benefit” and found the
    agency’s interpretation reasonable. Id. at *3, *6. The district
    court also noted that the Policy supported FWS’
    interpretation. See id. at *6–7.
    4
    See Auer v. Robbins, 
    519 U.S. 452
     (1997).
    14            FRIENDS OF ANIMALS V. USFWS
    The district court next held that FWS reasonably defined
    baseline conditions as suggested in the Safe Harbor Policy
    because the agency used the best techniques and information
    available. Id. at *8. The district court held that FWS’
    reliance on “resident” owl populations, rather than “floater”
    (i.e., young and displaced) owls, tracked the Safe Harbor
    Policy. Id. at *10. The district court also rejected Friends’
    argument that FWS’ survey data could not establish that
    non-baseline sites were “abandoned” because neither the
    Safe Harbor Policy nor other agency guidance requires
    baseline conditions to be designated based on
    “abandonment.” Id. at *11.
    Lastly, the district court found that FWS adequately
    considered impacts to critical habitat affected by the Oregon
    permit in the issued Biological Opinions. Id. at *12. The
    court rejected Friends’ argument that the Biological
    Opinions insufficiently analyzed important subsets of
    critical habitat because the Biological Opinions did
    “consider and assess[] the foraging, transience, and
    colonization value of the affected critical habitat . . . .” Id.
    The district court then turned to Friends’ NEPA claims.
    The district court held that FWS did not have to conduct a
    Supplemental EIS because the “2013 EIS accounted for the
    possibility that nonfederal lands could be included in the
    experiment” and the authorization of incidental take in non-
    baseline sites did “not constitute a substantial change
    relevant to environmental concerns.” Id. at *13. The district
    court also held that FWS did not have to analyze the
    experiment and permits in a single EIS. Id. at *14. Because
    “each action could exist without the other,” the experiment
    and the permits were not “connected actions.” Id.
    On appeal, Friends presses the same ESA and NEPA
    claims.

    ANALYSIS
    I. FWS complied with the ESA.
    Friends renews its same ESA arguments rejected by the
    district court. We reject them and conclude that FWS
    complied with the ESA.
    a. The “informational benefit” from the experiment
    may constitute a “net conservation benefit” under
    ESA regulations.
    As noted above, the ESA generally bars anyone—
    including the federal government—from “taking”
    endangered or threatened species or making significant
    modifications to their habitat that kill or injure wildlife. 
    16 U.S.C. § 1538
     (prohibiting the “take” of threatened or
    endangered species); 
    50 C.F.R. § 17.3
    (c)(3) (defining
    16           FRIENDS OF ANIMALS V. USFWS
    “harm” under the “take” definition to include significant
    modification of habitat).
    The ESA, however, carves out a few exceptions.
    Relevant here, FWS can issue a permit allowing someone to
    “take” an endangered or threatened species if it is “for
    scientific purposes or to enhance the propagation or survival
    of the affected species . . . .” 
    16 U.S.C. § 1539
    (a)(1)(A).
    And ESA regulations permit the agency to enter into Safe
    Harbor Agreements with non-federal landowners whose
    lands the agency wants to use for conservation efforts if the
    proposed actions are “reasonably expected to provide a net
    conservation benefit to the affected listed species” and
    “otherwise compl[y] with the Safe Harbor policy.” See 
    50 C.F.R. § 17.32
    (c)(1); (c)(2)(ii) (emphasis added).
    FWS designed its barred owl removal experiment
    relying on its authority to issue these permits and to enter
    into Safe Harbor Agreements. But Friends argues FWS
    cannot authorize this experiment because it does not provide
    a “net conservation benefit.” Their argument proceeds as
    follows: Because the ESA regulation does not define “net
    conservation benefit,” that term is ambiguous. The Safe
    Harbor Policy, however, defines “net conservation benefit.”
    64 Fed. Reg. at 32,722. And according to Friends, that
    definition of “net conservation benefit” in the Safe Harbor
    Policy supposedly requires direct recovery of the species,
    and thus does not include the “informational benefit” that
    FWS expects from its experiment.
    We disagree with Friends’ reading of “net conservation
    benefit.” For starters, “net conservation benefit” is not
    ambiguous—at least on whether that term includes
    informational benefit. The ESA defines “conservation” as
    “all methods and procedures” necessary for the recovery of
    the species, which “include, but are not limited to, all
    FRIENDS OF ANIMALS V. USFWS                  17
    activities associated with scientific resources management
    such as research.” 
    16 U.S.C. § 1532
    (3) (emphasis added).
    “Research” means “the collecting of information about a
    particular subject.”         Merriam-Webster Dictionary,
    https://www.merriam-webster.com/dictionary/research.
    And we generally assume that a word in an implementing
    regulation tracks the meaning of that same word in the
    authorizing statute. See Decker v. Nw. Envtl. Def. Ctr., 
    568 U.S. 597
    , 609 (2013) (regulations must be interpreted
    consistently with statute they implement).
    So the definition of “conservation” in the ESA—and, by
    extension, in the ESA regulation at issue—includes
    activities aimed at collecting information (such as the
    efficacy of barred owl removal as a conservation strategy).
    And thus “net conservation benefit” includes informational
    and research benefit contemplated by the barred owl removal
    experiment. Whether this informational benefit outweighs
    the harm done from any incidental take is an expert judgment
    that we generally defer to the agency. San Luis & Delta-
    Mendota Water Auth. v. Locke, 
    776 F.3d 971
    , 994 (9th Cir.
    2014).
    Ignoring the definition of “conservation” in the ESA,
    Friends insists that we should look at the definition of “net
    conservation benefit” in the agency’s Safe Harbor Policy:
    “the cumulative benefits of the management
    activities identified in a Safe Harbor
    Agreement that provide for an increase in a
    species’ population and/or the enhancement,
    restoration, or maintenance of the covered
    species’ suitable habitat within the enrolled
    property, taking into account the length of the
    Agreement and any off-setting adverse
    effects attributable to the incidental taking
    18            FRIENDS OF ANIMALS V. USFWS
    allowed by the enhancement of survival
    permit. Net conservation benefits must be
    sufficient to contribute, either directly or
    indirectly, to the recovery of the covered
    species.”
    64 Fed. Reg. at 32,722. According to Friends, the Policy’s
    definition requires that the permits directly cause an
    “increase” in either the northern spotted owl’s population or
    its suitable habitat. And because the information from the
    experiment does neither on its own, Friends argues that the
    experiment cannot qualify as a “net conservation benefit.”
    But even if we assume that the Safe Harbor Policy has
    the force of law, Friends’ reading of “net conservation
    benefit” remains unconvincing. 5 See W. Radio Servs. Co.,
    Inc., v. Espy, 
    79 F.3d 896
    , 900 (9th Cir. 1996) (“[W]e will
    review an agency’s alleged noncompliance with an agency
    pronouncement only if that pronouncement actually has the
    force and effect of law.”). To begin, the last sentence of the
    Policy’s definition states that “net conservation benefit”
    must “directly or indirectly” contribute to the recovery of the
    species. Id. at 32,722 (emphasis added). The experiment
    here “indirectly” aids the recovery of the northern spotted
    owl.
    Other parts of the Safe Harbor Policy also undermine
    Friends’ cramped reading of “net conservation benefit.”
    Much like we review an entire statute to determine a specific
    provision’s meaning under traditional canons of statutory
    interpretation, we must examine the entire Policy to discern
    the meaning of “net conservation benefit.” Cf. U.S. Nat’l
    5
    While the Safer Harbor Policy underwent a notice-and-comment
    process, it was not codified in the Code of Federal Regulations.
    FRIENDS OF ANIMALS V. USFWS                           19
    Bank of Or. v. Indep. Ins. Agents of America, Inc., 
    508 U.S. 439
    , 455 (1993) (When “expounding a statute, we must not
    be guided by a single sentence or member of a sentence, but
    look to the provisions of the whole law, and to its object and
    policy.”) (internal quotation marks omitted). And in
    responding to public comments asking to clarify the meaning
    of “net conservation benefit,” FWS stated three times that
    “net conservation benefits may result from . . . creating areas
    for testing and implementing new conservation strategies.”
    64 Fed. Reg. at 32,719 (Response 5), 32,720 (Response 11),
    32,722 (Purpose of the Policy) (emphasis added). FWS here
    is testing new conservation strategies by conducting the
    barred owl removal experiment.
    In short, we hold that “net conservation benefit” as used
    in the ESA regulation includes informational benefit
    provided by the barred owl removal experiment. 6
    b. FWS reasonably described baseline conditions
    using “resident” owl survey data.
    Friends also claims that FWS improperly defined
    baseline sites where it cannot remove the barred owls. 7 The
    6
    It does not necessarily mean that the agency can justify an
    incidental take of a threatened or endangered species based on
    speculative or questionable research. That issue goes to the “net
    conservation benefit”—i.e., whether the research data outweighs the
    harm caused by the take. Friends, however, does not appear to challenge
    FWS’ determination that the experiment will provide useful data.
    7
    As with its “net conservation benefit” argument, Friends’ “baseline
    conditions” claim presumes non-compliance with the Safe Harbor Policy
    and other agency guidance. We do not review claims of non-compliance
    with an agency’s own pronouncement unless that pronouncement carries
    the force of law. See W. Radio, 
    79 F.3d at 900
    . Here, we need not decide
    20             FRIENDS OF ANIMALS V. USFWS
    Safe Harbor Policy requires that each Safe Harbor
    Agreement fully describe “the agreed upon baseline
    conditions” for the covered species within the property. 64
    Fed. Reg. at 32,723. “Baseline conditions” are the
    “population estimates and distribution and/or habitat
    characteristics and determined area of the enrolled property
    that sustain seasonal or permanent use by the covered
    species . . . .” Id. at 32,722.
    For the Roseburg, Oxbow, and Weyerhaeuser Safe
    Harbor Agreements, FWS designated a site as “baseline”—
    and thus not subject to the permits’ incidental take
    authorizations—whenever a single resident spotted owl had
    been spotted on that site in annual surveys from 2013 to
    2015. For the Oregon Safe Harbor Agreement, FWS used
    the same methodology but relied on surveys from 2011 to
    2015.
    Friends argues that FWS’ methodology suffered two
    flaws. First, Friends claims that FWS determined that
    baseline sites were “effectively abandoned” but that the
    agency’s own policy statements show three to five years of
    survey data cannot establish “abandonment.”           This
    “abandonment” argument is a red herring. There is simply
    no requirement—in either the Safe Harbor Policy or the
    agency’s other guidance—that FWS designate baseline
    conditions based on “abandonment.” The Safe Harbor
    Policy does not mention “abandonment” in its discussion of
    baseline conditions. See 64 Fed. Reg. at 32,722–24. And
    the Safe Harbor Agreements make no such finding either.
    Each Safe Harbor Agreement determined that baseline sites
    were “unoccupied,” not “abandoned.” The guidance relied
    whether the Policy and other guidance carry the force of law because
    FWS in any event complied with both.
    FRIENDS OF ANIMALS V. USFWS                   21
    on by Friends explicitly distinguishes between “unoccupied”
    and “abandoned” sites.          The guidance states that
    “[o]ccupancy is an annual rate and is not equivalent to
    ‘abandoned,’ which is a permanent status.” And the
    guidance says unoccupied sites should be determined by
    using at least “3 years of survey.” FWS complied with this
    methodology by using three to five years of surveys in
    designating the Safe Harbor Agreements’ baseline
    conditions.
    Second, because the Safe Harbor Policy defines
    “baseline conditions” as including areas that sustain
    “seasonal” use, Friends alleges FWS erred in limiting
    baseline sites to only those areas where a “resident” spotted
    owl was detected and not considering “floaters” (young and
    displaced spotted owls). The Safe Harbor Policy instructs
    that determination of baseline conditions should be flexible
    and based on agreement between FWS and the landowner.
    64 Fed. Reg. at 32,719. Given the flexibility granted to the
    parties, we cannot say exclusion of “floater” owls violates
    the Safe Harbor Policy. As FWS explained, there is “no
    evidence that floaters (young and displaced territorial
    spotted owls) successfully breed unless they first become
    established on a territory” and are thus unlikely to contribute
    to the recovery of the species. It was reasonable for FWS
    and the parties to set baseline sites based on “resident” owls
    that are of primary conservation importance. Moreover, the
    Safe Harbor Agreements include special protections during
    nesting and roosting seasons in non-baseline areas, requiring
    permittees to “refrain from removal or alteration of habitat”
    within the core area containing nesting trees.
    22            FRIENDS OF ANIMALS V. USFWS
    c. FWS adequately analyzed the small portion of
    critical habitat affected by the Oregon permit.
    The ESA requires federal agencies to ensure that their
    actions will not destroy or adversely modify a species’
    designated critical habitat. 
    16 U.S.C. § 1536
    (a)(2). To this
    end, FWS issued a Biological Opinion for each permit. Each
    Biological Opinion concluded that the permit was unlikely
    to destroy or adversely modify the northern spotted owl’s
    critical habitat. 
    50 C.F.R. § 402.14
    (h)(iv)(A)–(B).
    Friends objects to the Biological Opinions for two
    reasons. First, Friends claims that the permits at issue
    “overlap with critical habitat on state lands” and that FWS
    failed to analyze this fact in the Biological Opinions. But
    Friends cannot point to anything in the administrative record
    showing that FWS failed to analyze affected critical habitat.
    Only the Oregon permit/Safe Harbor Agreement overlaps
    with critical habitat. Because the actual amount of critical
    habitat that would be destroyed by the experiment was
    unknown, FWS took a conservative approach, assuming the
    entire 3,345 acres of critical habitat in the Oregon lands
    would be removed.           Even under this conservative
    assumption, less than 0.04 percent of the spotted owl’s total
    critical habitat would be destroyed. FWS concluded such a
    “low level of potential loss would not impair the overall
    recovery of the spotted owl . . . .” We cannot say such a
    conclusion was erroneous.
    Second, Friends argues that the Biological Opinions
    were arbitrary and capricious because they analyze only one
    subset of designated critical habitat—nesting/roosting
    habitat—and ignore impacts to other subsets such as “habitat
    for foraging and/or transience or colonization stages of
    dispersal.” We agree with FWS that the Biological Opinions
    sufficiently analyzed the relevant subsets of critical habitat.
    FRIENDS OF ANIMALS V. USFWS                   23
    Contrary to Friends’ claim, the Oregon Biological Opinions
    did analyze the permit’s effect on foraging, transience, and
    colonization habitat, but still concluded that the effect would
    not appreciably reduce such subsets because of their
    “scattered nature” throughout the Oregon lands.
    But even without such an analysis, we would not
    consider the agency’s focus on nesting/roosting habitat to be
    arbitrary and capricious. FWS said in the Biological
    Opinion that nesting/roosting habitat is “likely the most
    important habitat in determining whether spotted owls can
    support themselves within a specific area.” Given its
    importance to spotted owl survival, we cannot say that the
    agency acted improperly by focusing its analysis on a vital
    habitat subset. See San Luis & Delta-Mendota, 776 F.3d at
    994 (agency’s scientific judgments owed great deference).
    We thus reject Friends’ critical habitat claims.
    II. FWS complied with NEPA.
    In 2013, FWS issued an Environmental Impact
    Statement (EIS) analyzing the experiment’s environmental
    impacts. Later, when FWS issued the permits and Safe
    Harbor Agreements, it conducted a less-intensive
    Environmental Assessment (EA) for each permit. All EAs
    concluded that the spotted owl would not be significantly
    affected. Friends contends FWS’ environmental analyses
    did not meet NEPA requirements in two ways. First,
    although FWS issued an initial EIS, Friends claims FWS had
    to issue a Supplemental Environmental Impact Statement
    (Supplemental EIS), instead of the lesser EAs, when it later
    issued the permits. Second, Friends argues FWS should
    have considered environmental effects of each permit with
    those from other permits and the broader experiment. We
    find FWS properly complied with its NEPA obligations.
    24           FRIENDS OF ANIMALS V. USFWS
    a. FWS did not have to conduct a Supplemental EIS
    when it issued the permits.
    NEPA does not expressly address when an agency must
    prepare a Supplemental EIS. Marsh v. Or. Nat. Res.
    Council, 
    490 U.S. 360
    , 370 (1989). But “NEPA cases have
    generally required agencies to file [a Supplemental EIS]
    when the remaining governmental action would be
    environmentally ‘significant.’” 
    Id. at 372
     (quoting Tenn.
    Valley Auth. v. Hill, 
    437 U.S. 153
    , 188 n.34 (1978)).
    Whether an action, such as issuing the permits at issue, has
    environmental significance is a “classic example of a factual
    dispute” that “implicates substantial agency expertise” to
    which “we must defer.” 
    Id.
     at 376–77.
    While NEPA does not squarely address Supplemental
    EIS obligations, the Council on Environmental Quality
    (CEQ) has issued regulations that “impose a duty on all
    federal agencies to prepare” a Supplemental EIS if “(i) the
    agency makes substantial changes to the proposed action that
    are relevant to environmental concerns; or (ii) there are
    significant new circumstances or information relevant to
    environmental concerns and bearing on the proposed action
    or its impacts.” Id. at 372; 
    40 C.F.R. § 1502.9
    (d)(1).
    CEQ has published more guidance, which our circuit has
    adopted as the proper framework for applying
    § 1502.9(d)(1). Russell Country Sportsmen v. U.S. Forest
    Serv., 
    668 F.3d 1037
    , 1045 (9th Cir. 2011) (citing Forty
    Most Asked Questions Concerning CEQ’s National
    Environmental Policy Act Regulations, 
    46 Fed. Reg. 18,026
    ,
    18,035 (Mar. 23, 1981)). Under this framework, a
    Supplemental EIS is not required if: “(1) the new alternative
    is a ‘minor variation of one of the alternatives discussed in
    the [original] EIS,’ and (2) the new alternative is
    FRIENDS OF ANIMALS V. USFWS                  25
    ‘qualitatively within the spectrum of alternatives that were
    discussed in the [original EIS].’” 
    Id.
    Friends argues that FWS had to issue a Supplemental
    EIS under either prong of § 1502.9(d)(1). First, Friends
    maintains that FWS made “substantial changes” to the
    “heart” of the barred owl removal experiment because the
    goal of the experiment was to conserve the northern spotted
    owl but the permits authorized the take of spotted owls.
    Second, Friends contends that the specifics of each permit
    and Safe Harbor Agreement constitute “significant new
    information” that was not considered in the initial EIS. We
    disagree on both points.
    First, the incidental take of northern spotted owls
    authorized by the permits is only a “minor variation” of the
    broader barred owl removal experiment analyzed in the
    original EIS. The central component of the action was and
    still is the removal of barred owls from treatment areas. The
    permits help the removal of barred owls. Though FWS
    stated that the permits would allow the experiment to
    proceed in the most efficient and complete manner, the
    experiment would still be possible without access to any
    non-federal lands. We thus agree with FWS that the permits
    were an ancillary aspect of the experiment and constitute a
    “minor variation.” See Russell, 
    668 F.3d at
    1048–49
    (holding supplementation not required where variation is a
    “secondary rather than primary” aspect of the action).
    Additionally, the permits and Safe Harbor Agreements
    were clearly “within the spectrum of alternatives” discussed
    in the 2013 EIS. 
    Id. at 1048
    . In the original EIS, FWS stated
    that “[w]here possible, we would seek cooperation from
    nonfederal landowners,” although “nonfederal lands would
    be included in the active experiment only if the landowners
    are willing.” Thus, the EIS adequately contemplated FWS’
    26            FRIENDS OF ANIMALS V. USFWS
    later issuance of the permits. And because issuance of the
    permits ultimately depended on the cooperation of non-
    federal parties, it “would be incongruous” with NEPA to
    conclude FWS was without power to proceed with the
    experiment until such specifics of the Safe Harbor
    Agreements were fully fleshed out and assessed in a
    Supplemental EIS. Cf. Robertson v. Methow Valley Citizens
    Council, 
    490 U.S. 332
    , 352–53 (1989).
    We are also satisfied that FWS conducted the required
    “hard look” review in determining that the permits were not
    environmentally significant. See Cal. ex rel. Imperial Cty.
    Air Pollution Control Dist. v. U.S. Dep’t of the Interior, 
    767 F.3d 781
    , 792 (9th Cir. 2014). FWS conducted an EA for
    each permit. Each EA determined the authorized incidental
    take of northern spotted owls was likely to be small because
    it would only occur if spotted owls repopulated non-baseline
    sites after barred owls were removed. In other words,
    spotted owls would be taken only if the experiment managed
    to increase the spotted owl’s population and range. And
    FWS concluded that such gains would be temporary, as
    barred owls would resume displacing the spotted owls after
    the experiment. In FWS’ opinion, the environmental effects
    of the experiment were the same with or without the permits.
    A Supplemental EIS is not required.
    b. The permits and the experiment need not be
    analyzed in a single EIS because they are not
    “connected actions.”
    An agency must discuss “connected actions” in a single
    EIS. 
    40 C.F.R. § 1501.9
    (e)(1). Friends claims that the
    broader experiment and the permits were “connected
    actions.” As Friends sees it, each permit and SHA depends
    on the experiment’s informational benefit to satisfy the “net
    conservation benefit” requirement. Friends thus claims that
    FRIENDS OF ANIMALS V. USFWS                    27
    FWS erred in analyzing the experiment separately from the
    permits and addressing each permit in isolation from the
    other permits.
    Actions are connected if they “[c]annot or will not
    proceed unless other actions are taken previously or
    simultaneously” or are “interdependent parts of a larger
    action and depend on the larger action for their justification.”
    
    Id.
     In applying § 1501.9(e)(1), we employ an “independent
    utility” test. Great Basin Mine Watch v. Hankins, 
    456 F.3d 955
    , 969 (9th Cir. 2006). “When one of the projects might
    reasonably have been completed without the existence of the
    other, the two projects have independent utility and are not
    ‘connected’ for NEPA’s purposes.” 
    Id.
     (citation omitted).
    The permits are not “connected” to the broader
    experiment because the experiment would proceed without
    the permits. Friends claims that each permit’s legality
    depends on the experiment. But access to any of the non-
    federal lands (let alone all of them) was not considered
    necessary by FWS to complete the experiment. While
    failure to gain access to non-federal lands could delay the
    result of the experiment, it would not altogether inhibit it.
    Put another way, “one of the projects”—the barred owl
    removal experiment—would be completed without the
    other, meaning the experiment and the permits have
    “independent utility” and are not “connected.” 
    Id.
     (emphasis
    added).
    The permits are also not “connected” to each other. Each
    permit has “independent utility” because the issuance of one
    permit did not depend on the issuance of any other permit.
    The EIS stated that each permit depended on “cooperation
    from nonfederal landowners” and “nonfederal lands would
    be included in the active experiment only if the landowners
    are willing.” FWS issued the permits individually to each
    28            FRIENDS OF ANIMALS V. USFWS
    landowner, and irrespective of whether the other permits
    would issue, so the permits are not “connected.” 
    Id.
    Because the permits and the experiment were not “connected
    actions,” FWS did not have to assess their environmental
    impacts together in a single document. 8
    CONCLUSION
    We hold that FWS complied with the ESA and NEPA in
    issuing the permits and Safe Harbor Agreements. We
    AFFIRM the district court’s grant of summary judgment for
    FWS.

    In the Roseburg-Oxbow final EA, FWS analyzed the cumulative
    effects of the Roseburg-Oxbow, Weyerhaeuser, and Oregon SHAs to
    “ensure a robust NEPA analysis.”
