Abstract

In this candidate notice of review (CNOR), we, the U.S. Fish and Wildlife Service (Service or FWS), present an updated list of plant and animal species that we regard as candidates for or have proposed for addition to the Lists of Endangered and Threatened Wildlife and Plants under the Endangered Species Act of 1973, as amended. This document also includes our findings on resubmitted petitions and describes our progress in revising the Lists of Endangered and Threatened Wildlife and Plants (Lists) during the period October 1, 2022, through September 30, 2024. Combined with other decisions for individual species that were published separately from this CNOR in the past two years, the current number of species that are candidates for listing or uplisting is 16 (as of September 30, 2024). Identification of candidate species can assist environmental planning efforts by providing advance notice of potential listings, and by allowing landowners, resource managers, States, Tribes, range countries, and other stakeholders to take actions to alleviate threats and thereby possibly remove the need to list species as endangered or threatened. Even if we subsequently list a candidate species, the early notice provided here could result in more options for species management and recovery by prompting earlier candidate conservation measures to alleviate threats to the species.

ACTION: Notification of review.

-----------------------------------------------------------------------

SUMMARY: In this candidate notice of review (CNOR), we, the U.S. Fish 
and Wildlife Service (Service or FWS), present an updated list of plant 
and animal species that we regard as candidates for or have proposed 
for addition to the Lists of Endangered and Threatened Wildlife and 
Plants under the Endangered Species Act of 1973, as amended. This 
document also includes our findings on resubmitted petitions and 
describes our progress in revising the Lists of Endangered and 
Threatened Wildlife and Plants (Lists) during the period October 1, 
2022, through September 30, 2024. Combined with other decisions for 
individual species that were published separately from this CNOR in the 
past two years, the current number of species that are candidates for 
listing or uplisting is 16 (as of September 30, 2024). Identification 
of candidate species can assist environmental planning efforts by 
providing advance notice of potential listings, and by allowing 
landowners, resource managers, States, Tribes, range countries, and 
other stakeholders to take actions to alleviate threats and thereby 
possibly remove the need to list species as endangered or threatened. 
Even if we subsequently list a candidate species, the early notice 
provided here could result in more options for species management and 
recovery by prompting earlier candidate conservation measures to 
alleviate threats to the species.

DATES: We are publishing this document on October 31, 2025. We will 
accept information on any of the species in this document at any time.

SUPPLEMENTARY INFORMATION:

Background

    The Endangered Species Act of 1973 (Act; 16 U.S.C. 1531 et seq.), 
as amended, requires that we identify species of wildlife and plants 
that are endangered or threatened based solely on the best scientific 
and commercial data available. As defined in section 3 of the Act, an 
endangered species is any species that is in danger of extinction 
throughout all or a significant portion of its range, and a threatened 
species is any species that is likely to become an endangered species 
within the foreseeable future throughout all or a significant portion 
of its range. Through the Federal rulemaking process, we add species 
that meet these definitions to the List of Endangered and Threatened 
Wildlife in title 50 of the Code of Federal Regulations (CFR) at Sec.  
17.11 (50 CFR 17.11) or the List of Endangered and Threatened Plants at 
50 CFR 17.12. As part of this process, we maintain a list of species 
that we regard as candidates for listing. A candidate species is one 
for which we have on file sufficient information on biological 
vulnerability and threats to support a proposal for listing as 
endangered or threatened, but for which preparation and publication of 
a proposal is precluded by higher priority listing actions. We may 
identify a species as a candidate for listing after we have conducted 
an evaluation of its status--either on our own initiative, or in 
response to a petition we have received. If we have made a finding on a 
petition to list a species and have found that listing is warranted but 
precluded by other higher priority listing actions, we will add the 
species to our list of candidates.
    We maintain this list of candidates for a variety of reasons: (1) 
To notify the public that these species are facing threats to their 
survival; (2) to provide advance knowledge of potential listings that 
could affect decisions of environmental planners and developers; (3) to 
provide information that may stimulate and guide conservation efforts 
that will remove or reduce threats to these species and possibly make 
listing unnecessary; (4) to request input from interested parties to 
help us identify those candidate species that may not require 
protection under the Act, as well as additional species that may 
require the Act's protections; and (5) to request necessary information 
for setting priorities for preparing listing proposals. We encourage 
collaborative conservation efforts for candidate species and offer 
technical and financial assistance to facilitate such efforts. For 
additional information regarding such

assistance, please contact the appropriate Office listed under Request 
for Information, below, or visit our website at: <a href="https://www.fws.gov/program/endangered-species/what-we-do">https://www.fws.gov/program/endangered-species/what-we-do</a>.

Previous CNORs

    We have been publishing CNORs since 1975. The most recent was 
published on June 27, 2023 (88 FR 41560). CNORs published since 1994 
are available on our website at <a href="https://www.fws.gov/library/collections/candidate-notice-review">https://www.fws.gov/library/collections/candidate-notice-review</a>. For copies of CNORs published 
prior to 1994, please contact the Branch of Delisting and Foreign 
Species or the Branch of Domestic Listing (see FOR FURTHER INFORMATION 
CONTACT, above).
    On September 21, 1983, we published guidance for assigning a 
listing priority number (LPN) for each candidate species (48 FR 43098). 
Using this guidance, we assign each candidate an LPN of 1 to 12, 
depending on the magnitude of threats, immediacy of threats, and 
taxonomic status; the lower the LPN, the higher the listing priority 
(that is, a species with an LPN of 1 would have the highest listing 
priority). Section 4(h)(3) of the Act (16 U.S.C. 1533(h)(3)) requires 
the Secretary to establish guidelines for such a priority-ranking 
system. As explained below, in using this system, we first categorize 
based on the magnitude of the threat(s), then by the immediacy of the 
threat(s), and finally by taxonomic status.
    Under this priority-ranking system, magnitude of threat can be 
either ``high'' or ``moderate to low.'' This criterion helps ensure 
that the species facing the greatest threats to their continued 
existence receive the highest listing priority. All candidate species 
face threats to their continued existence, so the magnitude of threats 
is in relative terms. For all candidate species, the threats are of 
sufficiently high magnitude to put them in danger of extinction or make 
them likely to become in danger of extinction in the foreseeable 
future. However, for species with higher magnitude threats, the threats 
have a greater likelihood of bringing about extinction or are expected 
to bring about extinction on a shorter timescale (once the threats are 
imminent) than for species with lower magnitude threats. Because we do 
not routinely quantify how likely or how soon extinction would be 
expected to occur absent listing, we must evaluate factors that 
contribute to the likelihood and time scale for extinction. We, 
therefore, consider information such as: (1) The number of populations 
or extent of range of the species affected by the threat(s), or both; 
(2) the biological significance of the affected population(s), taking 
into consideration the life-history characteristics of the species and 
its current abundance and distribution; (3) whether the threats affect 
the species in only a portion of its range, and, if so, the likelihood 
of persistence of the species in the unaffected portions; (4) the 
severity of the effects and the rapidity with which they have caused or 
are likely to cause mortality to individuals and accompanying declines 
in population levels; (5) whether the effects are likely to be 
permanent; and (6) the extent to which any ongoing conservation efforts 
reduce the severity of the threat(s).
    As used in our priority-ranking system, immediacy of threat is 
categorized as either ``imminent'' or ``nonimminent,'' and is based on 
when the threats will begin. If a threat is currently occurring or 
likely to occur in the very near future, we classify the threat as 
imminent. Determining the immediacy of threats helps ensure that 
species facing actual, identifiable threats are given priority for 
listing proposals over species for which threats are only potential or 
species that are intrinsically vulnerable to certain types of threats 
but are not known to be presently facing such threats.
    Our priority-ranking system has three categories for taxonomic 
status: Species that are the sole members of a genus; full species (in 
genera that have more than one species); and subspecies and distinct 
population segments of vertebrate species (DPSs).
    The result of the ranking system is that we assign each candidate 
an LPN of 1 to 12. For example, if the threats are of high magnitude, 
with immediacy classified as imminent, the listable entity is assigned 
an LPN of 1, 2, or 3 based on its taxonomic status (i.e., a species 
that is the only member of its genus would be assigned to the LPN 1 
category, a full species to LPN 2, and a subspecies or DPS would be 
assigned to LPN 3). In summary, the LPN ranking system provides a basis 
for making decisions about the relative priority for preparing a 
proposed rule to list a given species. No matter which LPN we assign to 
a species, each species included in this document as a candidate is one 
for which we have concluded that we have sufficient information to 
prepare a proposed rule for listing because it is in danger of 
extinction or likely to become endangered within the foreseeable future 
throughout all or a significant portion of its range.
    For more information on the process and standards used in assigning 
LPNs, a copy of the 1983 guidance is available at: <a href="https://www.govinfo.gov/content/pkg/FR-2016-07-27/pdf/2016-17818.pdf">https://www.govinfo.gov/content/pkg/FR-2016-07-27/pdf/2016-17818.pdf</a>. The 
species assessment and listing priority assignment form for each 
candidate contains the LPN chart and a more-detailed explanation--
including citations to, and more-detailed analyses of, the best 
scientific and commercial data available--for our determination of the 
magnitude and immediacy of threat(s) and assignment of the LPN; these 
forms are available for review on the website provided above in 
ADDRESSES.

Summary of This CNOR

    Since publication of the previous CNOR on June 27, 2023 (88 FR 
41560), we reviewed the available information on candidate species to 
ensure that a proposed listing is justified for each species, and 
reevaluated the relative LPN assigned to each species. We also 
evaluated the need to emergency list any of these species, particularly 
species with higher priorities (i.e., species with LPNs of 1, 2, or 3). 
This review and reevaluation ensures that we focus conservation efforts 
on those species at greatest risk.
    In addition to reviewing candidate species since publication of the 
last CNOR, we have worked on findings in response to petitions to list 
species, on proposed rules to list species under the Act, and on final 
listing determinations. Some of these findings and determinations have 
been completed and published in the Federal Register, while work on 
others is still under way (see Preclusion and Expeditious Progress, 
below, for details).
    Combined with other findings and determinations published 
separately from this CNOR, as of September 30, 2024, 16 candidate 
species are awaiting preparation of a proposed listing rule or ``not-
warranted'' finding. Table 5 (below) identifies these 16 candidate 
species, along with the 56 species proposed for listing (including one 
species proposed for listing due to similarity of appearance) as of 
September 30, 2024.
    Table 6 (below) lists the changes for species identified in the 
previous CNOR and includes 48 species identified in the previous CNOR 
as either proposed for listing or classified as candidates that are no 
longer in those categories because we have published a final listing 
rule.

Petition Findings

    The Act provides two mechanisms for considering species for 
listing. One method allows the Secretary, on the Secretary's own 
initiative, to identify species for listing under the standards of 
section 4(a)(1). The second method

[[Page 48914]]

provides a mechanism for the public to petition us to add a species to 
the Lists. As described further in the paragraphs that follow, the CNOR 
serves several purposes as part of the petition process: (1) In some 
instances (in particular, for petitions to list species that the 
Service has already identified as candidates on its own initiative), it 
serves as the initial petition finding; (2) for candidate species for 
which the Service has made a warranted-but-precluded petition finding, 
it serves as a ``resubmitted'' petition finding that the Act requires 
the Service to make each year; and (3) it documents the Service's 
compliance with the statutory requirement to monitor the status of 
species for which listing is warranted but precluded, and to ascertain 
if they need emergency listing.
    First, the CNOR serves as an initial 12-month finding in some 
instances. Under section 4(b)(3)(A) of the Act, when we receive a 
petition to list a species, we must determine within 90 days, to the 
maximum extent practicable, whether the petition presents substantial 
information indicating that listing may be warranted (a ``90-day 
finding''). If we make a positive 90-day finding, we must promptly 
commence a status review of the species under section 4(b)(3)(A), and 
then, in accordance with section 4(b)(3)(B), we must make, within 12 
months of the receipt of the petition, one of the following three 
possible findings (a ``12-month finding''):
    (1) The petitioned action is not warranted, in which case we must 
promptly publish the finding in the Federal Register;
    (2) The petitioned action is warranted (in which case we must 
promptly publish a proposed regulation to implement the petitioned 
action; once we publish a proposed rule for a species, sections 4(b)(5) 
and 4(b)(6) of the Act govern further procedures, regardless of whether 
or not we issued the proposal in response to a petition); or
    (3) The petitioned action is warranted, but (a) the immediate 
proposal of a regulation and final promulgation of a regulation 
implementing the petitioned action is precluded by pending proposals to 
determine whether any species is endangered or threatened, and (b) 
expeditious progress is being made to add qualified species to the 
Lists and to remove from the Lists species for which the protections of 
the Act are no longer necessary. We refer to this third option as a 
``warranted-but-precluded finding,'' and after making such a finding, 
we must promptly publish it in the Federal Register.
    We define ``candidate species'' to mean those species for which the 
Service has on file sufficient information on biological vulnerability 
and threats to support issuance of a proposed rule to list, but for 
which issuance of the proposed rule is precluded by higher priority 
listing actions (61 FR 64481; December 5, 1996). The standard for 
making a species a candidate through our own initiative is identical to 
the standard for making a warranted-but-precluded 12-month petition 
finding on a petition to list.
    Therefore, all candidate species identified through our own 
initiative already have received the equivalent of substantial 90-day 
and warranted-but-precluded 12-month findings. Nevertheless, if we 
receive a petition to list a species that we have already identified as 
a candidate, we review the status of the newly petitioned candidate 
species and in a CNOR publish specific section 4(b)(3) findings (i.e., 
substantial 90-day and warranted-but-precluded 12-month findings) in 
response to the petitions to list these candidate species. We publish 
these findings as part of the first CNOR following receipt of the 
petition.
    Second, the CNOR serves as a ``resubmitted'' petition finding. 
Section 4(b)(3)(C)(i) of the Act requires that when we make a 
warranted-but-precluded finding on a petition, we treat the petition as 
one that is resubmitted on the date of the finding. Thus, we must make 
a 12-month petition finding for each such species at least once a year 
in compliance with section 4(b)(3)(B) of the Act, until we publish a 
proposal to list the species or make a final not-warranted finding. We 
make these annual resubmitted petition findings through the CNOR. To 
the extent these annual findings differ from the initial 12-month 
warranted-but-precluded finding or any of the resubmitted petition 
findings in previous CNORs, they supersede the earlier findings, 
although all previous findings are part of the administrative record 
for the new finding, and in the new finding, we may rely upon them or 
include them by reference as appropriate, in addition to explaining why 
the finding has changed. We have identified the candidate species for 
which we received petitions and made a continued warranted-but-
precluded finding on a resubmitted petition by the code ``C'' in the 
category column on the left side of table 5, below.
    Third, through undertaking the analysis required to complete the 
CNOR, the Service determines if any candidate species needs emergency 
listing. Section 4(b)(3)(C)(iii) of the Act requires us to implement a 
system to monitor effectively the status of all species for which we 
have made a warranted-but-precluded 12-month finding and to make prompt 
use of the emergency listing authority under section 4(b)(7) to prevent 
a significant risk to the well-being of any such species. The CNOR 
plays a crucial role in the monitoring system that we have implemented 
for all candidate species by providing notice that we are actively 
seeking information regarding the status of those species. We review 
all new information on candidate species as it becomes available, 
prepare an annual species assessment form that reflects monitoring 
results and other new information, and identify any species for which 
emergency listing may be appropriate. If we determine that emergency 
listing is appropriate for any candidate, we will make prompt use of 
the emergency listing authority under section 4(b)(7) of the Act.
    A number of court decisions have elaborated on the nature and 
specificity of information that we must consider in making and 
describing the petition findings in the CNOR. The CNOR that published 
on November 9, 2009 (74 FR 57804), describes these court decisions in 
further detail. As with previous CNORs, we continue to incorporate 
information of the nature and specificity required by the courts. For 
example, we include a description of the reasons why the listing of 
every petitioned candidate species is both warranted and precluded at 
this time. We make our determinations of preclusion on a nationwide 
basis to ensure that the species most in need of listing will be 
addressed first and also because we allocate our listing budget on a 
nationwide basis. Our preclusion determinations are further based upon 
our budget for listing activities for non-listed species only, and we 
explain the priority system and why the work we have accomplished has 
precluded action on listing candidate species.
    In preparing this CNOR, we reviewed the current status of, and 
threats to, the 14 candidate species for which we have received a 
petition to list where we found the action warranted but precluded and 
2 species for which we continue to find uplisting warranted but 
precluded. We find that the immediate issuance of a proposed rule and 
timely promulgation of a final rule for each of these species has been, 
for the preceding months, and continues to be, precluded by higher 
priority listing actions. Summaries for the monarch butterfly and Rio 
Grande cutthroat trout are not included in this CNOR, as a proposed

[[Page 48915]]

listing rule (89 FR 100662) and 12-month finding (89 FR 99207), 
respectively, have been published prior to the publication of this 
document.
    The immediate publication of proposed rules to list or uplist these 
species was precluded by our work on higher priority listing actions, 
listed below, during the period from October 1, 2022, through September 
30, 2024. Below, we describe the actions that continue to preclude the 
immediate proposal and final promulgation of a regulation implementing 
each of the petitioned actions for which we have made a warranted-but-
precluded finding, and we describe the expeditious progress we are 
making to add qualified species to, and remove species from, the Lists. 
We will continue to monitor the status of all candidate species, 
including petitioned species, as new information becomes available to 
determine if a change in status is warranted, including the need to 
emergency list a species under section 4(b)(7) of the Act. As described 
above, under section 4 of the Act, we identify and propose species for 
listing based on the factors identified in section 4(a)(1)--either on 
our own initiative or through the mechanism that section 4 provides for 
the public to petition us to add species to the Lists of Endangered or 
Threatened Wildlife and Plants.

Preclusion and Expeditious Progress

    To make a finding that a particular action is warranted but 
precluded, the Service must make two determinations: (1) That the 
immediate proposal and timely promulgation of a final regulation is 
precluded by pending proposals to determine whether any species is 
endangered or threatened; and (2) that expeditious progress is being 
made to add qualified species to either of the Lists and to remove 
species from the Lists (16 U.S.C. 1533(b)(3)(B)(iii)).

Preclusion

    A listing proposal is precluded if the Service does not have 
sufficient resources available to complete the proposal because there 
are competing demands for those resources and the relative priority of 
those competing demands is higher. Thus, in any given fiscal year (FY), 
multiple factors dictate whether it will be possible to undertake work 
on a proposed listing regulation or whether promulgation of a proposal 
is precluded by higher priority listing actions--(1) the amount of 
resources available for completing the listing-related function; (2) 
the estimated cost of completing the proposed listing regulation; and 
(3) the Service's workload, along with the Service's prioritization of 
the proposed listing regulation, in relation to other actions in its 
workload.
Available Resources
    The resources available for listing-related actions are determined 
through the annual congressional appropriations process. In FY 1998 and 
for each fiscal year since then, Congress has placed a statutory cap on 
funds that may be expended for the Listing Program (spending cap). This 
spending cap was designed to prevent the listing function from 
depleting funds needed for other functions under the Act (for example, 
recovery functions, such as removing species from the Lists), or for 
other Service programs (see House Report 105-163, 105th Congress, 1st 
Session, July 1, 1997). The funds within the spending cap are available 
to support work involving the following listing actions: Proposed and 
final rules to add species to the Lists or to change the status of 
species from threatened to endangered; 90-day and 12-month findings on 
petitions to add species to the Lists or to change the status of a 
species from threatened to endangered; annual ``resubmitted'' petition 
findings on prior warranted-but-precluded petition findings as required 
under section 4(b)(3)(C)(i) of the Act; critical habitat petition 
findings; proposed rules designating critical habitat or final critical 
habitat determinations; and litigation-related, administrative, and 
program-management functions (including preparing and allocating 
budgets, responding to Congressional and public inquiries, and 
conducting public outreach regarding listing and critical habitat).
    For more than two decades, the size and cost of the workload in 
these categories of actions have far exceeded the amount of funding 
available to the Service under the spending cap for completing listing 
and critical habitat actions under the Act. As we cannot exceed the 
spending cap without violating the Anti-Deficiency Act (see 31 U.S.C. 
1341(a)(1)(A)), each year we have been compelled to determine that work 
on at least some actions was precluded by work on higher priority 
actions. We make our determinations of preclusion on a nationwide basis 
to ensure that the species most in need of listing will be addressed 
first, and because we allocate our listing budget on a nationwide 
basis. Through the listing cap and the amount of funds needed to 
complete court-mandated actions within the cap, Congress and the courts 
have in effect determined the amount of money remaining (after 
completing court-mandated actions) for listing activities nationwide. 
Therefore, the funds that remain within the listing cap--after paying 
for work needed to comply with court orders or court-approved 
settlement agreements--set the framework within which we make our 
determinations of preclusion and expeditious progress.
    For FY 2023, through the Consolidated Appropriations Act, 2023 
(Pub. L. 117-328, December 29, 2022), Congress appropriated $23,398,000 
for all domestic and foreign listing work. For FY 2024, through the 
Further Consolidated Appropriations Act, 2024 (Pub. L. 118-42, March 9, 
2024), Congress appropriated $22,000,000 for all domestic and foreign 
listing work. The amount of funding Congress will appropriate in future 
years is uncertain.
Costs of Listing Actions
    The work involved in preparing various listing documents can be 
extensive, and may include, but is not limited to: gathering and 
assessing the best scientific and commercial data available and 
conducting analyses used as the basis for our decisions; requesting 
peer and partner review on our analyses that support listing decisions 
and incorporating those comments, as appropriate; writing and 
publishing documents; and obtaining, reviewing, and evaluating public 
comments on proposed rules and incorporating relevant information from 
those comments into final rules. The number of listing actions that we 
can undertake in a given year also is influenced by the complexity of 
those listing actions; that is, more complex actions generally are more 
costly. Our practice of proposing to designate critical habitat 
concurrently with listing domestic species requires additional 
coordination and an analysis of the economic impacts of the 
designation, and thus adds to the complexity and cost of our work. 
Completing all of the outstanding listing and critical habitat actions 
has for so long required more funding than is available within the 
spending cap that the Service has developed several ways to prioritize 
its workload actions under the Act and to identify the work it can 
complete with the available funding for listing and critical habitat 
actions each year.
Prioritizing Listing Actions
    The Service's Listing Program workload is broadly composed of four 
types of actions, which the Service prioritizes as follows: (1) 
Compliance with court orders and court-approved settlement agreements 
requiring that petition findings or listing determinations or critical 
habitat

[[Page 48916]]

designations be completed by a specific date; (2) essential litigation-
related, administrative, and listing program-management functions; (3) 
section 4 (of the Act) listing and critical habitat actions with 
absolute statutory deadlines; and (4) section 4 listing actions that do 
not have absolute statutory deadlines.
    In previous years, the Service received many new petitions, 
including multiple petitions to list numerous species--in one example, 
a single petition sought to list 404 domestic species. The emphasis 
that petitioners placed on seeking listing for hundreds of species at a 
time through the petition process significantly increased the number of 
actions within the third category of our workload--actions that have 
absolute statutory deadlines for making findings on those petitions. In 
addition, the necessity of dedicating all of the Listing Program 
funding towards determining the status of 251 candidate species and 
complying with other court-ordered requirements between 2011 and 2016 
added to the number of petition findings awaiting action. Because we 
are not able to work on all of these actions at once, the Service's 
most recent effort to prioritize its workload focuses on addressing the 
backlog in petition findings that has resulted from the influx of large 
multi-species petitions and the 5-year period in which the Service was 
compelled to suspend making 12-month findings for most of those 
petitions. The number of petitions awaiting status reviews and 
accompanying 12-month findings illustrates the considerable extent of 
this backlog. As a result of the outstanding petitions to list hundreds 
of species, and our efforts to make initial petition findings within 90 
days of receiving the petition to the maximum extent practicable, at 
the beginning of FY 2024 we had 289 12-month petition findings yet to 
be completed.
    To determine the relative priorities of the outstanding 12-month 
petition findings, the Service developed a prioritization methodology 
(methodology) (81 FR 49248; July 27, 2016), after providing the public 
with notice and an opportunity to comment on the draft methodology (81 
FR 2229; January 15, 2016). Under the methodology, we assign each 12-
month finding to one of five priority bins: (1) The species is 
critically imperiled; (2) strong data are already available about the 
status of the species; (3) new science is underway that would inform 
key uncertainties about the status of the species; (4) conservation 
efforts are in development or underway and likely to address the status 
of the species; or (5) the available data on the species are limited. 
As a general matter, 12-month findings with a lower bin number have a 
higher priority than, and are scheduled before, 12-month findings with 
a higher bin number. However, we make some limited exceptions--for 
example, we may schedule a lower priority finding earlier if batching 
it with a higher priority finding would generate efficiencies. We may 
also consider whether there are any special circumstances whereby an 
action should be moved up (or down) in scheduling. For example, one 
limitation that might result in divergence from priority order is when 
the current highest priorities are clustered in a geographic area, such 
that our scientific expertise at the field office level is fully 
occupied with their existing workload. We recognize that the geographic 
distribution of our scientific expertise will in some cases require us 
to balance workload across geographic areas. Since before Congress 
first established the spending cap for the Listing Program in 1998, the 
Listing Program workload has required considerably more resources than 
the amount of funds Congress has allowed for the Listing Program. 
Therefore, it is important that we be as efficient as possible in our 
listing process.
    After finalizing the prioritization methodology, we then applied 
that methodology to develop multiyear workplans for domestic and 
foreign species for completing the outstanding status assessments and 
accompanying 12-month findings, along with other outstanding work such 
as designating critical habitat and acting on the status of candidate 
species.

Domestic Species Workplan

    The purpose of the National Listing Workplan (Workplan) is to 
provide transparency and predictability to the public about when the 
Service anticipates completing specific 12-month findings for domestic 
species while allowing for flexibility to update the Workplan when new 
information changes the priorities. In April 2023 and May 2024, the 
Service released updated Workplans for addressing the Act's domestic 
listing and critical habitat decisions over the subsequent 5 years. The 
updated May 2024 Workplan identified the Service's schedule for 
addressing the two domestic species on the candidate list and 
conducting 225 status reviews and accompanying 12-month findings by FY 
2028 for domestic species that have been petitioned for Federal 
protections under the Act. The National Listing Workplan is available 
online at: <a href="https://www.fws.gov/project/national-listing-workplan">https://www.fws.gov/project/national-listing-workplan</a>.

Foreign Species Workplan

    Similar to the National Listing Workplan, the Foreign Species 
Workplan provides the Service's multiyear schedule for addressing our 
foreign species listing workload. The Foreign Species Workplan provides 
transparency and predictability to the public about when the Service 
anticipates completing specific 12-month findings and candidate species 
while allowing for flexibility to update the Foreign Species Workplan 
when new information changes the priorities. In June 2023, the Service 
released its Foreign Species Workplan for addressing the Act's foreign 
listing decisions over the subsequent 5 years. A more recent Foreign 
Species Workplan was published in November 2024; however, this CNOR 
addresses the time period of October 1, 2022, through September 30, 
2024, so for the purposes of this CNOR, we reference the June 2023 
version. The Foreign Species Workplan identifies the Service's 
prioritization for addressing the 14 foreign species on the candidate 
list and 48 status reviews and accompanying 12-month findings for 
petitioned species, and it identifies which actions we plan to complete 
by FY 2029. As we implement our Foreign Species Workplan and work on 
12-month findings and proposed rules for the highest priority species, 
we increase efficiency by preparing multi-species proposals when 
appropriate, and these may include species with lower priority if they 
overlap geographically or have the same threats as one of the highest 
priority species. The Foreign Species Workplan is available online at: 
<a href="https://www.fws.gov/project/foreign-species-listing-workplan">https://www.fws.gov/project/foreign-species-listing-workplan</a>.
    For the 12-month findings, consistent with our prioritization 
methodology, within the five priority bins we determine the relative 
timing of foreign species actions using sub-ranking considerations, 
i.e., as tie-breakers for determining relative timing within each of 
the five bins (see the August 9, 2021, CNOR (86 FR 43474-43476) for a 
detailed description of tie-breakers). We consider the extent to which 
the protections of the Act would be able to improve conditions for that 
species and its habitat relative to the other species within the same 
bin, and in doing so, we give weight to the following considerations, 
in order from greater weight to lesser weight.
    1. FWS Office of Law Enforcement (OLE) enforcement capacity;

[[Page 48917]]

    2. Species in trade to or from the United States;
    3. Species in trade through U.S. ports (i.e., in-transit or 
transshipment);
    4. Within the United States, interstate trade;
    5. Status under the Convention on International Trade in Endangered 
Species of Wild Fauna and Flora (CITES); and
    6. International Union for Conservation of Nature (IUCN) Red List 
status.

Prioritization of Domestic and Foreign Species

    An additional way in which we determine relative priorities of 
outstanding actions for species in the section 4 program is application 
of the listing priority guidelines (48 FR 43098; September 21, 1983; 
see Previous CNORs, above). Proposed rules for listing foreign species, 
including foreign candidate species, are generally lower in priority 
than domestic listings because we generally have more resources and 
authorities to achieve higher conservation outcomes when listing 
domestic species. The Service has a responsibility to conserve both 
domestic and foreign species; however, our choice to dedicate the bulk 
of our funding cap to domestic actions is a rational one given the 
likelihood of obtaining better conservation outcomes for domestic 
species versus foreign species under the Act.
    The Act makes no distinction between foreign species and domestic 
species in listing species as endangered or threatened. The protections 
of the Act generally apply to both listed foreign species and domestic 
species, and section 8 of the Act provides authorities for 
international cooperation on foreign species. However, some significant 
differences in the Service's authorities result in differences in our 
ability to affect conservation for foreign and domestic species under 
the Act. The major differences are that the Service has no regulatory 
jurisdiction over take of a listed species in a foreign country, or of 
trade in listed species outside the United States by persons not 
subject to the jurisdiction of the United States (see 50 CFR 17.21). 
The Service also does not designate critical habitat within foreign 
countries or in other areas outside of the jurisdiction of the United 
States (50 CFR 424.12(g)).
    Additionally, section 7 of the Act in part requires Federal 
agencies to ensure that activities they authorize, fund, or carry out 
are not likely to jeopardize the continued existence of the species or 
destroy or adversely modify its critical habitat, and to enter into 
consultation with the Service if a Federal action may affect a listed 
species or its critical habitat. An ``action'' that is subject to the 
consultation provisions of section 7(a)(2) is defined in our 
implementing regulations at 50 CFR 402.02 as all activities or programs 
of any kind authorized, funded, or carried out, in whole or in part, by 
Federal agencies in the United States or upon the high seas. In view of 
this regulatory definition, foreign species are rarely subject to 
section 7 consultation, apart from consultations for permits issued 
under the Act. This differs from the considerable benefits section 7 
affords to domestic species whose life cycle occurs in whole or in part 
in the United States, and for which we do designate critical habitat, 
which are routinely subject to section 7 consultations and the 
conservation benefits that result from those.
    These differences in the Service's authorities for foreign and 
domestic species under the Act, including relating to take, critical 
habitat, and section 7 consultation, mean that listing foreign species 
is likely to have relatively less conservation effect than for domestic 
species. The protections of the Act through listing are likely to have 
their greatest conservation effect for foreign species that are in 
trade to, from, through, or within the United States. The majority 
(likely 12 out of the 14) of current foreign candidate species are not 
known to be in trade. Therefore, we made a rational decision to 
dedicate more resources to listing domestic species.
    Additionally, proposed rules for reclassification of threatened 
species status to endangered species status (uplisting) are generally 
lower in priority because, as listed species, they are already afforded 
the protections of the Act and implementing regulations. However, for 
efficiency reasons, we may choose to work on a proposed rule to 
reclassify a species to endangered species status if we can combine 
this action with higher priority work.

Listing Program Workload

    The National Listing Workplan that the Service released in 2024 
outlined work for domestic species over the period from FY 2024 to FY 
2028. The Foreign Species Workplan that the Service released in 2023 
outlined work for foreign species over the period from FY 2024 to FY 
2029. Tables 1 and 2 under Expeditious Progress, below, identify the 
higher priority listing actions that we completed through FY 2024 
(September 30, 2024), as well as those we have been working on in FY 
2024 but have not yet completed. For FY 2023 and FY 2024, our workload 
includes 48 12-month findings or proposed listing actions that are at 
various stages of completion at the time of this finding. In addition 
to the actions scheduled in the National Listing Workplan and the 
Foreign Species Workplan (``Workplans''), the overall Listing Program 
workload also includes development and revision of regulations required 
by new court orders or settlement agreements to address the 
repercussions of any new court decisions, and proposed and final 
critical habitat designations or revisions for species that have 
already been listed. The Service's highest priorities for spending its 
funding in FY 2023 and FY 2024 were actions included in the Workplans 
and actions required to address court decisions.

Expeditious Progress

    As explained above, a determination that listing is warranted but 
precluded must also demonstrate that expeditious progress is being made 
to add and remove qualified species to and from the Lists. Please note 
that in the Code of Federal Regulations, the ``Lists'' are grouped as 
one list of endangered and threatened wildlife (see 50 CFR 17.11(h)) 
and one list of endangered and threatened plants (see 50 CFR 17.12(h)). 
However, the ``Lists'' referred to in the Act mean one list of 
endangered species (wildlife and plants) and one list of threatened 
species (wildlife and plants). For the purposes of evaluating our 
expeditious progress, when we refer to the ``Lists,'' we mean this 
latter grouping of one list of endangered species and one list of 
threatened species.
    As with our ``precluded'' finding, the evaluation of whether 
expeditious progress is being made is a function of the resources 
available and the competing demands for those funds. As discussed 
earlier, the FY 2023 appropriations law appropriated $23,398,000 for 
all domestic and foreign listing activities, and the FY 2024 
appropriations law appropriated $22,000,000 for all domestic and 
foreign listing activities.
    As discussed below, given the limited resources available for 
listing, the competing demands for those funds, and the completed work 
catalogued in the tables below, we find that we are making expeditious 
progress to add qualified species to the Lists and to remove from the 
Lists species for which the protections of the Act are no longer 
necessary.
    The work of the Service's domestic listing and foreign listing 
programs in FY 2023 and FY 2024 (as of September

[[Page 48918]]

30, 2024) included all three of the steps necessary for adding species 
to the Lists: (1) Identifying species that may warrant listing 
(including 90-day petition findings); (2) undertaking an evaluation of 
the best available scientific data about those species and the threats 
they face to determine whether or not listing is warranted (a status 
review and, for petitioned species, an accompanying 12-month finding); 
and (3) adding qualified species to the Lists (by publishing proposed 
and final listing rules). We explain in more detail how we are making 
expeditious progress in all three of the steps necessary for adding 
qualified species to the Lists (identifying, evaluating, and adding 
species). Subsequent to discussing our expeditious progress in adding 
qualified species to the Lists, we explain our expeditious progress in 
removing from the Lists species that no longer require the protections 
of the Act.
    First, we are making expeditious progress in identifying species 
that may warrant listing. In FY 2023 and FY 2024 (as of September 30, 
2024), we completed 90-day findings on petitions to list 21 domestic 
species and 5 foreign species.
    Second, we are making expeditious progress in evaluating the best 
scientific and commercial data available about species and threats they 
face (status reviews) to determine whether or not listing is warranted. 
In FY 2023 and FY 2024 (as of September 30, 2024), we completed 12-
month findings for 99 domestic species and 1 foreign species. In 
addition, we initiated 12-month findings for 89 domestic species, 23 
foreign species, and 2 candidates. Although we did not complete all of 
those actions during FY 2023 or FY 2024 (as of September 30, 2024), we 
made expeditious progress towards doing so by initiating and making 
progress on the status reviews to determine whether adding these 
species to the Lists is warranted.
    Third, we are making expeditious progress in adding qualified 
species to the Lists. In FY 2023 and FY 2024 (as of September 30, 
2024), we published final listing rules for 48 domestic species and 5 
foreign species, including final critical habitat designations for 22 
of those domestic species and final protective regulations under the 
Act's section 4(d) for 33 of those domestic species and 2 foreign 
species. In addition, we published proposed rules to list an additional 
45 domestic species and 6 foreign species (including concurrent 
proposed critical habitat designations for 24 domestic species and 
concurrent protective regulations under the Act's section 4(d) for 15 
domestic species and 1 foreign species).
    Fourth, we are also making expeditious progress in removing 
(delisting) species, as well as reclassifying endangered species to 
threatened species status (downlisting). Delisting and downlisting 
actions are funded through the recovery line item in the budget of the 
Endangered Species Program. Thus, delisting and downlisting actions do 
not factor into our assessment of preclusion; that is, work on recovery 
actions does not preclude the availability of resources for completing 
new listing work. However, work on recovery actions does count towards 
our assessment of making expeditious progress because the Act states 
that expeditious progress includes both adding qualified species to, 
and removing qualified species from, the Lists of Endangered and 
Threatened Wildlife and Plants. In FY 2023 and FY 2024 (as of September 
30, 2024), we finalized downlisting rules for 6 domestic species with 
concurrent final protective regulations under the Act's section 4(d), 
finalized delisting rules for 34 domestic species, proposed delisting 
rules for 9 domestic species, and completed a 90-day finding for 1 
domestic species.

Preclusion and Expeditious Progress

    The tables below catalog the Service's progress in FY 2023 and FY 
2024 (as of September 30, 2024) as it pertains to our evaluation of 
preclusion and expeditious progress. Table 1 includes completed and 
published domestic and foreign listing actions. Table 2 includes 
domestic and foreign listing actions funded and initiated in previous 
fiscal years and in FY 2023 and FY 2024 that were not yet complete as 
of September 30, 2024. Table 3 includes completed and published 
proposed and final downlisting and delisting actions for domestic and 
foreign species.

    Another way that we have been expeditious in making progress in 
adding and removing qualified species to and from the Lists is that we 
have made our actions as efficient and timely as possible, given the 
requirements of the Act and regulations and constraints relating to 
workload and personnel. We are continually seeking ways to streamline 
processes or achieve economies of scale, such as batching related 
actions together for publication. Given our limited budget for 
implementing section 4 of the Act, these efforts also contribute toward 
our expeditious progress in adding and removing qualified species to 
and from the Lists.

Findings for Petitioned Candidate Species

    For all 14 candidates, we continue to find that listing is 
warranted but precluded as of the date of publication of this document. 
In the course of preparing proposed listing rules or not-warranted 
petition findings, we continue to monitor new information about these 
species' status so that we can make prompt use of our authority under 
section 4(b)(7) of the Act in the case of an emergency posing a 
significant risk to any of these species.
    Below are updated summaries for 14 of the petitioned candidates for 
which we published findings under section 4(b)(3)(B) of the Act and did 
not change the LPN. We note that species-specific discussions below are 
summaries. More detailed information is available in the associated 
species assessment forms, including information on relevant

[[Page 48924]]

developments with respect to the species since publication of the last 
CNOR, which are available on <a href="https://www.regulations.gov">https://www.regulations.gov</a> under docket 
number FWS-HQ-ES-2023-0246.
    In accordance with section 4(b)(3)(C)(i), we treat any petitions 
for which we made warranted-but-precluded 12-month findings within the 
past year as having been resubmitted on the date of the warranted-but-
precluded finding. We are making continued warranted-but-precluded 12-
month findings on the petitions for these species.

Jamaican Kite Swallowtail

    The Jamaican kite swallowtail (Protographium (Eurytides) 
marcellinus) is a small blue-green and black butterfly endemic to 
Jamaica. This butterfly is regarded as Jamaica's most endangered 
butterfly. On January 10, 1994, we received a petition from Ms. Dee E. 
Warenycia to list seven foreign swallowtail butterflies, including the 
Jamaican kite swallowtail (Protographium (Eurytides) marcellinus), 
under the Act. On May 10, 1994, we published in the Federal Register 
(59 FR 24117) a 90-day finding in which we announced that the petition 
to add the seven species of foreign swallowtail butterflies contained 
substantial information indicating that listing may be warranted for 
all species. On December 7, 2004, we published in the Federal Register 
(69 FR 70580) our finding that listing the species was warranted but 
precluded by higher priority actions, and we added the entity to our 
list of candidate species.
    The Jamaican kite swallowtail is restricted to limestone forests; 
breeding populations only occur in rare, dense stands of its only known 
larval host plant, black lancewood (Oxandra lanceolata). Five known 
sites have supported colonies of the Jamaican kite swallowtail. Two of 
the sites may be extirpated, the status of one site is uncertain, and 
two sites are viable with strong numbers in some years. There is no 
known estimate of population size, and numbers of mature adults are low 
in most years; however, occasionally there are strong flight seasons in 
which adult densities are relatively higher.
    The primary threat to the Jamaican kite swallowtail is habitat loss 
and fragmentation. Forests were cleared for agriculture and timber 
extraction, and more recently for sapling cutting for yam sticks, fish 
pots, or charcoal. Additional threats include mining for limestone that 
is used for roadbuilding and bauxite production that is an important 
economic activity, and charcoal-making also carries the risk of fire. 
Only around 8 percent of the total land area of Jamaica is natural 
forest with minimal human disturbance. Collection and trade of the 
species occurred in the past. Currently, however, this threat may be 
negligible because of heavy fines under the Jamaican Wildlife 
Protection Act. Predation from native predators, including spiders, the 
Jamaican tody (Todus todus), and praying mantis (Mantis religiosa), may 
be adversely affecting the Jamaican kite swallowtail, especially in the 
smaller subpopulations. In years with large populations of spiders, 
very few swallowtail larvae survive. Additionally, this species may be 
at greater risk of extinction due to natural events such as hurricanes.
    Since 2001, the Jamaican kite swallowtail has been protected under 
the Jamaican Wildlife Protection Act. The species is also included in 
their National Strategy and Action Plan on Biological Diversity. The 
two strongest subpopulations occur in protected areas, although habitat 
destruction within these areas continues. Since 1985, the Jamaican kite 
swallowtail has been categorized on IUCN's Red List as vulnerable, but 
the assessment is marked as ``needs updating.'' This species is not 
included in the Appendices to CITES or the European Union Wildlife 
Trade Regulations.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the Jamaican kite swallowtail was assigned an 
LPN of 2. After reevaluating the factors affecting the Jamaican kite 
swallowtail for this CNOR, we have determined that no change in LPN is 
warranted. Only five small subpopulations of the species are known, and 
as few as two of these subpopulations may presently be viable. 
Therefore, an LPN of 2 remains valid to reflect imminent threats of 
high magnitude.

Kaiser-i-Hind Swallowtail

    Kaiser-i-Hind swallowtail (Teinopalpus imperialis) is a large, 
ornate, and colorful swallowtail butterfly that displays sexual 
dimorphism (sexes differ in size and coloration). The species is native 
to the Himalayan regions of Bhutan, China, India, Laos, Myanmar, Nepal, 
Thailand, and Vietnam. On January 10, 1994, we received a petition from 
Ms. Dee E. Warenycia to list seven different butterfly species, 
including the Kaiser-i-Hind swallowtail butterfly, under the Act. On 
May 10, 1994, we published in the Federal Register (59 FR 24117) a 90-
day finding in which we announced that the petition to add the seven 
species of foreign butterflies contained substantial information 
indicating that listing may be warranted for all species. On December 
7, 2004, we published in the Federal Register (69 FR 70580) our finding 
that listing the species was warranted but precluded by higher priority 
actions, and we added the entity to our list of candidate species.
    The Kaiser-i-Hind swallowtail has a large range and was likely more 
widespread historically; however, it is currently restricted to higher 
elevations, 1,500 to 3,000 meters (m) (4,900 to 10,000 feet (ft)) above 
sea level, in the foothills of the Himalayan Mountains and other 
mountainous regions farther east. The species prefers undisturbed 
(primary) broad-leaved-evergreen forests or montane deciduous forests. 
Specific details on locations or population status are not readily 
available, and despite widespread distribution, populations are 
described as being local and never abundant.
    Habitat destruction negatively affects this species. Comprehensive 
information on the rate of degradation of Himalayan forests containing 
the Kaiser-i-Hind swallowtail is not available, but ongoing habitat 
loss is consistently reported as one of the primary threats to the 
species. In China and India, the Kaiser-i-Hind swallowtail populations 
are affected by habitat modification and destruction due to commercial 
and illegal logging, as well as clearing for agriculture in India. In 
Nepal, the species is affected by habitat disturbance and destruction 
resulting from mining, wood collection for use as fuel, deforestation, 
collection of fodders and fiber plants, forest fires, invasion of 
bamboo species into the oak forests, agriculture, and grazing animals. 
In Vietnam, the forest habitat is reportedly declining. Additionally, 
collection for commercial trade is also regarded as a threat to the 
species. The Kaiser-i-Hind swallowtail is highly valued and has been 
collected and traded despite various prohibitions. Although it is 
difficult to assess the potential impacts from collection, the removal 
of individuals from the wild in combination with other stressors 
contributes to local extirpations.
    In China, the species is protected by the Law of the People's 
Republic of China on the Protection of Wildlife. In India, the species 
is listed on Schedule II of the Indian Wildlife Protection Act. In 
Thailand, all butterflies in the genus Teinopalpus, including the 
Kaiser-i-Hind swallowtail, are listed under Thailand's Wild Animal 
Reservation and Protection Act. In Vietnam, the species is listed as 
``vulnerable'' in the 2007 Vietnam Red Data Book and is

[[Page 48925]]

reported to be the most valuable of all butterflies in Vietnam. In 
2006, the species was listed on Vietnam's Schedule IIB of Decree No. 32 
on management of endangered, precious, and rare forest plants and 
animals. Since 1996, the Kaiser-i-Hind swallowtail has been categorized 
on the IUCN Red List as lower risk/near threatened, but IUCN indicates 
that this assessment needs updating. The Kaiser-i-Hind swallowtail has 
been included in CITES Appendix II since 1987. Additionally, the 
Kaiser-i-Hind swallowtail is listed on Annex B of the European Union 
Wildlife Trade Regulations; species listed on Annex B require an import 
permit.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the Kaiser-i-Hind swallowtail was assigned an 
LPN of 8. After reevaluating the threats to this species for this CNOR, 
we have determined that no change in its LPN of 8 is warranted. The 
species has a wide distribution, although populations are local and 
never abundant. Habitat loss and collection are expected to continue in 
the future. Therefore, an LPN of 8 remains valid to reflect imminent 
threats of moderate magnitude.

Black-Backed Tanager

    The black-backed tanager (Tangara peruviana) is a vibrant and 
patterned bird endemic to the coastal Atlantic Forest region of 
southeastern Brazil. The species is known to historically occur in the 
coastal states of Rio de Janeiro, S[atilde]o Paulo, Paran[agrave], and 
Santa Catarina, Brazil. On May 6, 1991, we received a petition from the 
International Council for Bird Preservation (ICBP) to list 53 different 
bird species, including the black-backed tanager, under the Act. On 
December 16, 1991, we published in the Federal Register (56 FR 65207) a 
90-day finding in which we announced that the petition to add 53 
species of foreign birds contained substantial information indicating 
that listing may be warranted for all species. On May 21, 2004, we 
published in the Federal Register (69 FR 29354) our resubmitted 
petition findings that listing the species was warranted but precluded 
by higher priority actions, and we added the entity to our list of 
candidate species.
    The black-backed tanager is generally restricted in range and is 
associated with sand forest ``restinga'' habitat, which is a coastal 
component habitat of the greater Atlantic Forest complex of Brazil. The 
black-backed tanager is generally considered not rare within suitable 
habitat, with periodic local fluctuations in numbers owing to seasonal 
movements. The species is described as a regional migrant and is one of 
just a few tanagers known to migrate seasonally within the coastal 
Atlantic Forest region of Brazil. The best available information 
indicates the range is severely fragmented, consisting of approximately 
316,000 square kilometers (km\2\) (122,000 square miles (mi\2\)) of 
breeding range with a slightly larger nonbreeding range of 377,000 
km\2\ (146,000 mi\2\). The population size is estimated between 2,500 
and 10,000 mature adults. Both the habitat and species population are 
decreasing.
    The primary factor affecting this species is the rapid and 
widespread loss and fragmentation of habitat, mainly due to urban 
expansion and beachfront development. Much of the species' suitable 
habitat in Rio de Janeiro and Paran[aacute] has been destroyed. As much 
as 88 to 95 percent of the area historically covered by tropical 
forests within the Atlantic Forest biome has been lost or severely 
degraded as the result of human activities. Intact lowland forest, 
restinga, and mangrove habitat used by resident black-backed tanagers 
on the northern part of Santa Catarina Island (in the state of Santa 
Catarina) is unprotected, making the species vulnerable to extirpation 
on the island as development looms. Sea-level rise may alter the 
regional vegetation and structure and exacerbate the threat of habitat 
loss from ongoing coastal development.
    The black-backed tanager is classified as vulnerable by the IUCN. 
The species is also listed as vulnerable in Brazil and protected by 
law. It is not included in the Appendices to CITES, although it has 
infrequently been illegally sold in the pet trade.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), we assigned the black-backed tanager an LPN 
of 8. After reevaluating the available information for this CNOR, we 
have determined that no change to an LPN is warranted. The magnitude of 
threats to the black-backed tanager is moderate, based on its likely 
decreasing population size and widespread and ongoing habitat loss, 
although a recent evaluation of its population size is lacking. Small 
portions of the species' range occur in six protected areas, but these 
areas are not effectively protected. Therefore, an LPN of 8 remains 
valid for this species to reflect imminent threats of moderate 
magnitude.

Bogot[aacute] Rail

    The Bogot[aacute] rail (Rallus semiplumbeus) is a medium-sized, 
nonmigratory bird that occurs in the eastern Andean mountain range of 
Colombia at elevations from 2,500-4,000 m (8,200-13,000 ft) above sea 
level. On May 6, 1991, we received a petition from the ICBP to list 53 
foreign bird species, including the Bogot[aacute] rail, as endangered 
or threatened species under the Act. On December 16, 1991, we published 
in the Federal Register (56 FR 65207) a 90-day finding in which we 
announced that the petition to add 53 species of foreign birds 
contained substantial information indicating that listing may be 
warranted for all species. On May 21, 2004, we published in the Federal 
Register (69 FR 29354) our resubmitted petition findings that listing 
the species was warranted but precluded by higher priority actions, and 
we added the entity to our list of candidate species.
    The rail is found in savanna and p[aacute]ramo (high-elevation 
habitats above tree line) marshes surrounding Bogot[aacute], Colombia, 
on the Ubat[eacute]-Bogot[aacute] Plateau. The species relies on 
specific vegetation in wetland and lakeshore habitats at high 
elevations in the eastern flank of the eastern Andean mountain range of 
Colombia. The bird requires vegetation associated with these habitats 
for breeding and foraging. As of 2016, the population was estimated 
between 1,000 and 2,500 individuals, and the estimated extent of the 
resident/breeding habitat was 11,200 km\2\ (4,300 mi\2\) and shrinking.
    The primary threat to the rail is habitat loss and degradation of 
wetlands. Suitable habitat for the Bogot[aacute] rail occurs around the 
most populated area in Colombia with approximately 11 million people in 
the greater Bogot[aacute] metropolitan area. Wetlands in the area cover 
only approximately 3 percent of their historical extent. Although 
portions of the Bogot[aacute] rail's range occur in protected areas 
such as Chingaza National Park and Carpanta Biological Reserve, most 
savanna wetlands are virtually unprotected. Ongoing threats to 
remaining major wetlands include encroachment of human infrastructure 
and agriculture that causes loss of habitat and altered water levels, 
soil erosion, eutrophication caused by untreated effluent and 
agrochemicals, hunting, wildfire, and incidental spread of invasive 
species.
    The Bogot[aacute] rail is listed as endangered by IUCN. The species 
is not known to be in international trade and is not included in the 
Appendices to CITES.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the Bogot[aacute] rail was assigned an LPN of 
2. After reevaluating the threats to this species for this CNOR, we 
have determined that

[[Page 48926]]

no change in the LPN for the species is warranted. The species' range 
is very small, fragmented, and rapidly contracting because of ongoing 
widespread habitat loss and degradation of wetlands. Therefore, an LPN 
of 2 remains valid for this species to reflect imminent threats of high 
magnitude.

Bras[iacute]lia Tapaculo

    The Bras[iacute]lia tapaculo (Scytalopus novacapitalis) is a small, 
gray, ground-dwelling bird with limited flight ability. It is endemic 
to the Cerrado in Brazil, the largest tropical savanna in the world 
with a mosaic of habitats composed mostly of savannas and patches of 
dry forests. On May 6, 1991, we received a petition from the ICBP to 
list 53 different bird species, including the Bras[iacute]lia tapaculo, 
as endangered or threatened species under the Act. On December 16, 
1991, we published in the Federal Register (56 FR 65207) a 90-day 
finding in which we announced that the petition to add 53 species of 
foreign birds contained substantial information indicating that listing 
may be warranted for all species. On May 21, 2004, we published in the 
Federal Register (69 FR 29354) our resubmitted petition findings that 
listing the species was warranted but precluded by higher priority 
actions, and we added the entity to our list of candidate species.
    The Bras[iacute]lia tapaculo's core habitat is dense, narrow strips 
of swampy gallery forests at elevations of approximately 800-1,000 m 
(2,600-3,300 ft). The species' range is located within six protected 
areas within the Cerrado and is not found outside protected areas. The 
Bras[iacute]lia tapaculo is described as rare, and the population size 
is unknown. However, the population is assumed to be declining because 
of the ongoing decline of the species' gallery forest habitat.
    The primary threat to the Bras[iacute]lia tapaculo is ongoing 
habitat loss and fragmentation from agricultural activities. The 
Cerrado is the largest, most diverse, and possibly most threatened 
tropical savanna in the world. Land is converted for intensive grazing 
and mechanized agriculture, mostly for soybean production. Agriculture 
causes direct effects to gallery forests from wetland drainage and 
diversion of water for irrigation, as well as burning to create space. 
The species' habitat has been less directly affected by clearing for 
agriculture than the surrounding Cerrado. However, it is unclear how 
much core gallery forest has been destroyed because of habitat 
conversion for agriculture. Additionally, changes in precipitation and 
temperature patterns may also be negatively altering the Cerrado and 
reducing the amount of specialized habitat for the species.
    The IUCN lists the species as endangered, and the Brazilian Red 
List assessed the species as endangered, because the species' small, 
fragmented range is continuing to decline in area and quality. 
International trade is not a significant threat to the species, and the 
species is not included in the Appendices to CITES.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), we assigned the Bras[iacute]lia tapaculo an 
LPN of 2. After reevaluating the available information for this CNOR, 
we have determined that no change to an LPN is warranted. The species 
occurs in only a handful of small, protected areas, and is reported as 
rare. Habitat conversion is ongoing. Therefore, an LPN of 2 remains 
valid for this species to reflect imminent threats of high magnitude.

Chatham Islands Oystercatcher

    The Chatham Islands oystercatcher (Haematopus chathamensis; 
formerly referred to as the Chatham oystercatcher) is the rarest 
oystercatcher in the world, endemic to the four islands of the Chatham 
Island group 860 km (530 mi) east of mainland New Zealand. On November 
28, 1980, we received a petition from the ICBP to list 79 bird species, 
of which 19 were species on U.S. territory and 60 were foreign species, 
including Chatham Islands oystercatcher, as endangered or threatened 
species under the Act. On May 12, 1981, we published in the Federal 
Register (46 FR 26464) a 90-day finding in which we announced that the 
petition contained substantial information indicating that listing may 
be warranted for 77 of the 79 bird species, including the Chatham 
Islands oystercatcher. On May 21, 2004, we published in the Federal 
Register (69 FR 29354) our resubmitted petition findings that listing 
the species was warranted but precluded by higher priority actions, and 
we added the entity to our list of candidate species.
    Chatham Islands oystercatchers are restricted to the coasts, mainly 
occurring along rocky shores, including wide volcanic rock platforms, 
and occasionally on sandy or gravelly beaches. Humans inhabit the two 
largest islands, Chatham and Pitt Islands, while South East and Mangere 
Islands are uninhabited nature reserves. Isolated pairs may also breed 
on other smaller islands in the archipelago. The population of the 
species is approximately 250 mature individuals. The Chatham Islands 
oystercatcher uses its long, sturdy bill to hammer open mollusks from 
rocky shores and to probe and peck for worms and other small 
invertebrates in sand, gravel, or tidal debris. Pairs occupy their 
breeding and feeding territories all year, and females lay clutches of 
one to three eggs in scrape nests (shallow-rimmed depressions in soil 
or vegetation) on sandy beaches, or among rocks above the shoreline. 
Mean longevity has been estimated at 7.7 years, and the oldest banded 
bird lived more than 30 years.
    Predation of eggs and chicks (and to a lesser extent, predation of 
adults) is likely the primary threat to the Chatham Islands 
oystercatcher. Mangere and South East Islands are free of all mammalian 
predators; nonnative mammalian predators inhabit Chatham and Pitt 
Islands. Feral cats are the most common predator of oystercatcher eggs. 
Trampling of nests by livestock (sheep and cattle) and humans has been 
noted on beaches. Additionally, nonnative Marram grass (Ammophila 
arenaria) has altered the sand dunes and leaves few open nesting sites. 
Consequently, the Chatham Islands oystercatcher is forced to nest 
closer to shore where nests are vulnerable to high tides and storm 
surges. Up to 50 percent of eggs have been lost because of storms or 
high tides. Projected rise in sea level associated with climate change 
will likely increase storm frequency and severity, putting at risk most 
shorelines that the Chatham Islands oystercatcher relies on for nesting 
habitat.
    The species has experienced a three-fold increase in its population 
since the first reliable census was conducted in 1987. Most of this 
increase occurred during a period of intensive management, especially 
predator control, from 1998 through 2004. Some of these efforts 
continue at a reduced level because of a lack of resources but are 
still effective at reducing trampling, predation, and loss of nests/
eggs. The Chatham Island Oystercatcher Recovery Plan guides 
conservation actions for the species. The New Zealand Department of 
Conservation lists the Chatham Islands oystercatcher as nationally 
critical, and it is protected under New Zealand's Wildlife Act. It is 
classified as endangered on the IUCN Red List, and the species is not 
included in the Appendices to CITES and not known to be in 
international trade.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the Chatham Islands oystercatcher was 
assigned an LPN of 8. After reevaluating the available information for 
this CNOR, we have determined that no change in the LPN is warranted. 
Although the

[[Page 48927]]

population appears to have stabilized, it remains very small 
(approximately 250 mature individuals), and occupied breeding habitat 
is also small (fewer than 800 hectares (2,000 acres)). Active 
management has been instrumental in maintaining stable population 
levels, but the species continues to face threats to its nests and 
habitat. Therefore, an LPN of 8 is valid for this species to reflect 
imminent threats of moderate magnitude.

Ghizo White-Eye

    The Ghizo white-eye (Zosterops luteirostris) is a passerine 
(perching) bird described as ``warbler-like.'' It is endemic to the 
small island of Ghizo within the Solomon Islands in the South Pacific 
Ocean, east of Papua New Guinea. On November 28, 1980, we received a 
petition from the ICBP to list 79 bird species, of which 19 were 
species on U.S. territory and 60 were foreign species, including the 
Ghizo white-eye, as endangered or threatened species under the Act. On 
May 12, 1981, we published in the Federal Register (46 FR 26464) a 90-
day finding in which we announced that the petition contained 
substantial information indicating that listing may be warranted for 77 
of the 79 bird species, including the Ghizo white-eye. On May 21, 2004, 
we published in the Federal Register (69 FR 29354) our resubmitted 
petition findings that listing the species was warranted but precluded 
by higher priority actions, and we added the entity to our list of 
candidate species.
    The Ghizo white-eye prefers old-growth forest patches that cover 
approximately 1 km\2\ (0.4 mi\2\) of Ghizo Island. The species has been 
observed in forest edge, regrowth, and mature secondary forest. Limited 
information is available to determine whether sustainable populations 
can exist outside of forested habitats. The population size of the 
Ghizo white-eye is approximately 250 to 999 mature individuals in an 
estimated area of 35 km\2\ (14 mi\2\).
    Habitat loss is the primary threat to the species. Logging, 
conversion of forest for agricultural purposes, and local resource 
extraction for firewood are the main causes for loss of old-growth and 
secondary-growth forests. Human population growth in the Solomon 
Islands has contributed to development on Ghizo Island, such as 
construction of temporary housing. Additionally, catastrophic events, 
such as the 2007 tsunami, degraded forested areas that were found less 
likely to support the species even 5 years later in 2012. Sea-level 
rise in the future and an increase in storms could result in coastal 
flooding and erosion, saltwater intrusion, and damage to inland 
habitats.
    The IUCN Red List classifies this species as endangered. It is not 
included in the Appendices to CITES, and this species is not known to 
be in international trade.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the Ghizo white-eye was assigned an LPN of 2. 
After reevaluating the available information for this CNOR, we find 
that no change in the LPN is warranted. The species has a small 
population size, and suitable habitat is declining. Therefore, an LPN 
of 2 remains valid for this species to reflect imminent threats of high 
magnitude.

Helmeted Woodpecker

    The helmeted woodpecker (Celeus galeatus) is a small, nonmigratory 
woodpecker native to regions of southern Brazil, eastern Paraguay, and 
northeastern Argentina. It is one of the rarest woodpeckers in the 
Americas. On May 6, 1991, we received a petition from ICBP requesting 
the addition of 53 foreign bird species, including helmeted woodpecker, 
as endangered or threatened species under the Act. On December 16, 
1991, we published in the Federal Register (56 FR 65207) a 90-day 
finding in which we announced that the petition contained substantial 
information indicating that listing may be warranted for the 53 bird 
species, including the helmeted woodpecker. On May 21, 2004, we 
published in the Federal Register (69 FR 29354) our resubmitted 
petition findings that listing the species was warranted but precluded 
by higher priority actions, and we added the entity to our list of 
candidate species. At the time of the petition, the helmeted woodpecker 
was classified as Drycopus galeatus. We recognized the helmeted 
woodpecker in the genus Celeus in 2021 (as reflected in our May 3, 
2022, CNOR (87 FR 26152)), and we recognize the species as C. galeatus 
and treat D. galeatus and Hylatomus galeatus as synonyms.
    Helmeted woodpeckers prefer mature trees in old-growth tropical and 
subtropical semi-deciduous forests as well as in mixed deciduous-
coniferous forests in the southern Atlantic Forest up to elevations of 
1,000 m (3,280 ft). The species typically forages in the midstory of 
the tree canopy, pecking at wet bark and rotten wood. Its diet is not 
well known, but it has been observed eating insect larvae, ants, 
berries, and small fruit. The species seems to favor nesting cavities 
in dead or decaying trees. A portion of the nest cavities used by 
helmeted woodpeckers have partly covered openings that may help to 
conceal the cavities from predators.
    The primary threat to the species is habitat loss, degradation, and 
fragmentation, which includes loss of nesting cavities. The Atlantic 
Forest biome has lost 88 to 95 percent of the tropical forests to human 
activities. Currently, less than 1 percent of the remaining Atlantic 
Forest is primary forest preferred by the helmeted woodpecker. The 
species occurs in 17 protected areas throughout its range, although 
selective logging and other activities continue to degrade the habitat.
    The helmeted woodpecker is listed as endangered in Brazil and as 
vulnerable by the IUCN. The species is not included in the Appendices 
to CITES and not known to be in international trade.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), we assigned the helmeted woodpecker an LPN of 
8. After reevaluating the available information for this CNOR, we find 
that no change in the LPN for the species is warranted. The species is 
rare, and although the species may have a wider distribution, loss of 
primary Atlantic Forest habitat is ongoing. Therefore, an LPN of 8 
remains valid to reflect imminent threats of moderate magnitude.

Lord Howe Island Pied Currawong

    The Lord Howe Island pied currawong (Strepera graculina crissalis) 
is a large, crow-like bird that is endemic to Lord Howe Island, off the 
coast of New South Wales, Australia. On November 28, 1980, we received 
a petition from the ICBP to list 79 bird species, of which 19 were 
occurring on U.S. territory and 60 were foreign species, including Lord 
Howe Island pied currawong, as endangered or threatened species under 
the Act. On May 12, 1981, we published in the Federal Register (46 FR 
26464) a 90-day finding in which we announced that the petition 
contained substantial information indicating that listing may be 
warranted for 77 of the 79 bird species, including the Lord Howe Island 
pied currawong. On May 21, 2004, we published in the Federal Register 
(69 FR 29354) our resubmitted petition findings that listing the 
species was warranted but precluded by higher priority actions, and we 
added the entity to our list of candidate species.
    The Lord Howe Island pied currawong is a subspecies of the pied 
currawong, and occurs throughout the island, although it is most 
numerous in

[[Page 48928]]

mountainous regions. The subspecies breeds in rainforests and palm 
forests, particularly along streams, and descends to forage in 
lowlands. It is omnivorous, eating fruits, seeds, snails, insects, and 
small vertebrates such as rats and mice, small birds, and bird eggs and 
nestlings. Lord Howe Island pied currawongs are bold and inquisitive 
birds that readily adapt to the presence of humans and can occupy areas 
around human settlements, in addition to natural habitats. They are 
territorial during the breeding season, with some territories defended 
in the nonbreeding seasons. The average territory size is between 4.4 
to 7.3 hectares (11 to 18 acres).
    The primary threats to the subspecies are the introduction of 
nonnative rodents to the island ecosystem and the effects of climate 
change. The Lord Howe Island pied currawong has persisted among 
invasive black rats (Rattus rattus). However, because currawongs often 
prey on small rodents and are naturally curious, they were subject to 
nontarget poisoning during an islandwide rat-baiting program. Around 
half the population was taken into captivity to protect them during the 
rodent eradication efforts, and they have subsequently been released 
back into the wild. Additionally, the effects of climate change may 
affect the cloud layer on the island's mountaintops, resulting in 
drying of the forest where the subspecies procures roughly half its 
food. The small, isolated population of currawongs on Lord Howe Island 
is at risk from loss of genetic diversity and stochastic (random) 
environmental events. However, this population may have always been 
small and may not have the capacity for additional growth.
    The Australian Government owns Lord Howe Island. Approximately 75 
percent of the island, plus all outlying islets and rocks within the 
Lord Howe Island group, is protected under the Permanent Park Preserve. 
The Lord Howe Island Biodiversity Management Plan is the formal 
recovery plan for threatened species and communities of the Lord Howe 
Island Group. Following the removal of poison bait traps in 2020, 
monitoring is underway across the island to see if it has become 
rodent-free. The New South Wales Threatened Species Conservation Act of 
1995 lists the Lord Howe Island pied currawong as vulnerable, as does 
Australia's Environment Protection and Biodiversity Conservation Act 
List of Threatened Fauna. The subspecies is not listed on the IUCN Red 
List, is not included in the Appendices to CITES, and is not known to 
be in international trade.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the Lord Howe Island pied currawong was 
assigned an LPN of 6. After reevaluating the threats to the Lord Howe 
Island pied currawong for this CNOR, we have determined that no change 
in the LPN for the subspecies is warranted. The small population faces 
risks from nontarget poisoning from rodent control, although 
significant conservation efforts have been implemented. Therefore, 
based on the best information available, an LPN of 6 remains valid to 
reflect nonimminent threats of high magnitude.

Okinawa Woodpecker

    The Okinawa woodpecker (Dendrocopos noguchii) is a relatively large 
woodpecker endemic to Okinawa Island, Japan, and one of the world's 
rarest woodpecker species. Much of the mature forest that supports the 
species is located within the Jungle Warfare Training Center (formerly 
known as the Northern Training Area or Camp Gonsalves), part of the 
U.S. Marine Corps installation on Okinawa Island. On November 28, 1980, 
we received a petition from the ICBP to list 79 bird species, of which 
19 were occurring on U.S. territory and 60 were foreign species, 
including the Okinawa woodpecker, as endangered or threatened species 
under the Act. On May 12, 1981, we published in the Federal Register 
(46 FR 26464) a 90-day finding in which we announced that the petition 
contained substantial information indicating that listing may be 
warranted for 77 of the 79 bird species, including the Okinawa 
woodpecker. On May 21, 2004, we published in the Federal Register (69 
FR 29354) our resubmitted petition findings that listing the species 
was warranted but precluded by higher priority actions, and we added 
the entity to our list of candidate species. At the time of the 
petition, the Okinawa woodpecker (Dendrocopos noguchii) was classified 
as Sapheopipo noguchii. We recognized the Okinawa woodpecker in the 
genus Dendrocopos in 2009, and we recognize the species as D. noguchii 
and treat S. noguchii as a synonym (74 FR 40540, August 12, 2009, p. 
40548).
    The Okinawa woodpecker's main breeding areas lie in the northern 
part of Okinawa Island, including well-forested areas of Yambaru, a 
region of approximately 300 km\2\ (116 mi\2\). Population surveys have 
found that the number of Okinawa woodpeckers detected at Yambaru sites 
increases as the area of hardwood forest increases. The species feeds 
on large arthropods, notably beetle larvae, spiders, moths, and 
centipedes, as well as fruit, berries, seeds, acorns, and other nuts. 
Both males and females search dead and live tree trunks and bamboo in 
old-growth forests, but males also forage on the ground, sweeping away 
leaf-litter and probing for soil-dwelling prey. The Okinawa woodpecker 
nests in the decaying heartwood of large trees that are at least 25 
centimeters (9.8 inches) in diameter and 3 to 10 m (9.8 to 33 ft) off 
the ground, which are typically found in mature forests that are at 
least 30 years old.
    The primary threats to the Okinawa woodpecker are deforestation in 
the Yambaru region and introduced predators such as feral dogs and 
cats, small Indian mongoose (Urva auropunctata), and Japanese weasel 
(Mustela itatsi). As of the mid 1990s, only 40 km\2\ (15 mi\2\) of 
suitable habitat was available for the Okinawa woodpecker, mostly in 
the Jungle Warfare Training Center, which is relatively undisturbed. 
Much of the remaining old-growth forest in Yambaru is protected by 
Japanese legislation, and forests have been regrowing following a 
reduction in logging in recent decades. While forest regrowth is 
reaching ages that meet minimum suitability requirements for Okinawa 
woodpeckers and protected areas have improved the habitat, suitable 
habitat for the species remains fragmented and old-growth forest is 
scarce within the species' range. Mongoose control fences were erected 
in 2005 and 2006, and efforts to eradicate mongoose from the Yambura 
forest are ongoing and appear to be effective. Complete eradication of 
mongooses from the Yambaru region is targeted for 2027. Efforts to 
control feral cats have been less successful.
    The Japanese Government established Yambaru National Park in 2016. 
In July 2021, the United Nations Educational, Scientific, and Cultural 
Organization (UNESCO) added Amami-Oshima Island; Tokunoshima Island; 
the northern part of the main Okinawa Island, which contains Yambaru 
National Park; and Iriomote Island to the list of natural World 
Heritage sites. The species is listed as critically endangered in the 
Red List of Threatened Birds in Japan and is protected from acquisition 
and transfer under Japan's wildlife protection system. The Okinawa 
woodpecker is not included in the Appendices to CITES and is not known 
to be in international trade.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the Okinawa woodpecker was assigned an LPN of 
2.

[[Page 48929]]

After reevaluating the best available information for this CNOR, we 
have determined that no change in LPN for the species is warranted. The 
population is very small, and threats to its old-growth habitat and 
predation by nonnative mammals are ongoing. The Japanese Government is 
actively taking steps to address the threats of habitat loss and 
predation, but the threats remain high in magnitude due to the species' 
restricted range, small population size, and historical habitat loss. 
Therefore, an LPN of 2 remains valid for this species to reflect 
imminent threats of high magnitude.

Orange-Fronted Parakeet

    The orange-fronted parakeet (Cyanoramphus malherbi) is the rarest 
parakeet in New Zealand and the remaining naturally occurring colonies 
are restricted to three valleys on the South Island in the Canterbury 
Mountains. Captive-bred orange-fronted parakeets have been translocated 
to four predator-free islands, as well as Brook Waim[amacr]rama 
Sanctuary on the South Island. On November 28, 1980, we received a 
petition from the ICBP to list 79 bird species, of which 19 were 
occurring on U.S. territory and 60 were foreign species, including 
orange-fronted parakeet, as endangered or threatened species under the 
Act. On May 12, 1981, we published in the Federal Register (46 FR 
26464) a 90-day finding in which we announced that the petition 
contained substantial information indicating that listing may be 
warranted for 77 of the 79 bird species, including the orange-fronted 
parakeet. On May 21, 2004, we published in the Federal Register (69 FR 
29354) our resubmitted petition findings that listing the species was 
warranted but precluded by higher priority actions, and we added the 
entity to our list of candidate species.
    Orange-fronted parakeet populations on New Zealand's South Island 
inhabit subalpine mature beech forests (Nothofagus spp.), making their 
nests within natural cavities of these trees. Orange-fronted parakeets 
rely heavily on beech seeds as a major component of their diet, but 
also feed on a range of plant material including buds, sprouts, fruits, 
blossoms, leaves, ferns, and grasses; they also eat invertebrates such 
as aphids and caterpillars. Breeding is linked with the irregular 
seeding of beech trees. During mast years, in which seed production 
levels are high, parakeet numbers can increase substantially.
    The primary threats affecting the species on the mainland are 
predation by nonnative mammals (rats and stoats (Mustela erminea)), as 
well as habitat destruction due to deforestation. Numbers of nonnative 
mammals spike during mast years, due to abundant food sources, and thus 
orange-fronted parakeets are particularly vulnerable to predation in 
those years. Habitat loss and degradation has historically affected 
large areas of native forest on the mainland. Removal of mature beech 
trees with nest cavities has increased competition with other native 
parakeets for nest sites. Trade of this species is not known to be a 
threat.
    The New Zealand Department of Conservation (NZDOC) initiated a 
captive-breeding program and established small populations on four 
predator-free islands, one of which is self-sustaining. Another 
population has been introduced to a predator-free wildlife sanctuary 
with suitable beech forest habitat on the South Island. The species was 
uplisted from nationally endangered to nationally critical by the NZDOC 
in 2016; it is protected under New Zealand's Wildlife Act and is listed 
as critically endangered on the IUCN's Red List. The orange-fronted 
parakeet is included in Appendix II to CITES.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the orange-fronted parakeet was assigned an 
LPN of 8. After reevaluating the threats to the orange-fronted parakeet 
for this CNOR, we have determined that no change in LPN for the species 
is warranted. The current population is small, and the species' 
distribution is limited. Nonnative predators and loss of suitable 
habitat continue to threaten the species. The NZDOC is actively aiding 
the recovery of the species. Therefore, an LPN of 8 remains valid to 
reflect imminent threats of moderate magnitude.

Takah[emacr]

    The takah[emacr] (Porphyrio hochstetteri) is the largest extant 
rail in the world. The species is flightless, native to the South 
Island of New Zealand, and present on the North Island, other offshore 
islands, and Kahurangi National Park due to reintroduction and 
conservation efforts. On November 28, 1980, we received a petition from 
the ICBP to list 79 bird species, of which 19 were occurring on U.S. 
territory and 60 were foreign species, including the takah[emacr], as 
endangered or threatened species under the Act. On May 12, 1981, we 
published in the Federal Register (46 FR 26464) a 90-day finding in 
which we announced that the petition contained substantial information 
indicating that listing may be warranted for 77 of the 79 bird species, 
including the takah[emacr]. On May 21, 2004, we published in the 
Federal Register (69 FR 29354) our resubmitted petition findings that 
listing the species was warranted but precluded by higher priority 
actions, and we added the entity to our list of candidate species.
    The takah[emacr] was once widespread in the forest and grassland 
ecosystems of the South Island. Since the mid-1990s, the species 
remains present in only a relatively small area of the Murchison 
Mountains. In their relict range, takah[emacr] are largely herbivorous, 
feeding on tussocks (clumps of long grass that are thicker and longer 
than the grass growing around them). In the winter, the birds move into 
forested valleys, where their major food source is the rhizomes of 
thousand-leaved ferns (Hypolepis millefolium). In introduced 
populations at secure sites, takah[emacr] exhibit more generalist 
behavior, eating fallen fruits, small reptiles, and chicks of other 
bird species. The species is largely solitary and will not form dense 
colonies, even in optimal habitat, and will aggressively defend their 
territories, which can be up to 100 hectares (247 acres).
    Primary threats to the takah[emacr] include hunting, competition 
from nonnative species, disease outbreaks in the captive population, 
and nonnative predators such as stoats and weasels. Stoats and weasels 
appear to be the most significant predator to takah[emacr]. The NZDOC 
is actively managing populations through conservation efforts that 
include captive-rearing and reintroductions, predator control, 
management of grassland habitats, and adaptive research. The 
conservation efforts have slowly increased the number of populations 
and the species' overall population size.
    New Zealand considers the takah[emacr] a nationally vulnerable 
species, and it is protected under New Zealand's Wildlife Act. The 
takah[emacr] is listed as endangered on the IUCN Red List. The species 
is not known to be in international trade, and the species is not 
included in the Appendices to CITES.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the takah[emacr] was assigned an LPN of 8. 
After reevaluating the threats to the takah[emacr] for this CNOR, we 
have determined that no change in LPN for the species is warranted. The 
takah[emacr] has a small population size and limited range. The NZDOC 
is actively managing threats to aid in the recovery of the species. 
Therefore, the LPN remains at 8 to reflect imminent threats of low to 
moderate magnitude.

Yellow-Browed Toucanet

    The yellow-browed toucanet (Aulacorhynchus huallagae) is a member 
of the toucan family that occurs in the Andes Mountains in Peru. On May 
6, 1991, we received a petition from the ICBP to list 53 different bird 
species, including the yellow-browed toucanet, under the Act. On 
December 16, 1991, we published in the Federal Register (56 FR 65207) a 
90-day finding in which we announced that the petition to add 53 
species of foreign birds contained substantial information indicating 
that listing may be warranted for all species. On May 21, 2004, we 
published in the Federal Register (69 FR 29354) our resubmitted 
petition findings that listing the species was warranted but precluded 
by higher priority actions, and we added the entity to our list of 
candidate species.
    The yellow-browed toucanet relies on humid montane forests on the 
eastern slope of the Andes in north-central Peru, at elevations of 
2,000-2,600 m (6,562-8,530 ft). The species currently occupies three 
small locations. Habitat is dominated by tall Clusia (Clusia spp.) 
trees, where the species forages in the canopy for fruit and seeds and 
uses cavities in the trees to nest. The species is most frequently seen 
in pairs but is occasionally found in small groups of three to four 
individuals.
    Deforestation for livestock, agriculture, timber, and gold mining 
appears to be the primary threat to the viability of the yellow-browed 
toucanet. Habitat loss and destruction from deforestation for 
agriculture have been widespread in the region. Given the inherent 
threats to small populations (e.g., loss of genetic diversity via 
genetic drift, stochastic environmental events), continued habitat loss 
and degradation will exacerbate the risk to the species.
    The species is listed as endangered in the IUCN Red List. The 
species is not included in the Appendices of CITES and is not known to 
be in international trade.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the yellow-browed toucanet was assigned an 
LPN of 2. After reevaluating the available information for this CNOR, 
we find that no change in the LPN is warranted. The estimated 
population is small within a restricted range. The magnitude of threats 
to the habitat remains high, and its population is likely declining. 
Therefore, an LPN of 2 remains valid for this species to reflect 
imminent threats of high magnitude.

Colorado Delta Clam

    The Colorado Delta clam (Mulinia modesta; junior synonym = M. 
coloradoensis) is a relatively large, light-colored estuarine bivalve 
that was once very abundant at the head of the Gulf of California in 
the Colorado River estuary. The species currently occurs in the upper, 
northern, and central portions of the Gulf of California, and is 
capable of living in salinities ranging from brackish (mixture of salt 
and fresh water) to full seawater. In March 2012, the Colorado Delta 
clam became a candidate species through the Arizona Ecological Services 
field office (FWS 2012, entire). A 12-month finding published in the 
Federal Register on April 25, 2013 (78 FR 24604), determined that the 
species warrants protection, but was precluded from listing at the 
time.
    The species inhabits shallow, muddy waters of the coast and 
requires adequate substrate and water salinity to successfully breed 
and develop. The range of the species is relatively large, although 
densities are significantly lower than they were historically.
    We are not aware of any estimates of the total population for the 
entire range of the species. The historical population of the Colorado 
Delta clam in the upper Gulf of California was estimated to be at least 
5 billion individuals, accounting for 84-95 percent of all bivalve 
mollusks in the upper Gulf. However, after decades of dam building on 
the Colorado River and its tributaries, the Colorado Delta clam is 
estimated to have lost 94% of its population in the upper Gulf since 
dam construction began. Environmental changes to the estuary associated 
with reduced river flow include increased salinity, decreased sediment 
load, decreased input of naturally derived nutrients, and elimination 
of the spring/summer flood. From the 1990s until 2017, 0 percent of the 
Colorado River flowed into the Gulf. Since 2017, 2 percent of the river 
flow has reached the Gulf of California. Low flows are expected to 
continue or worsen if anticipated drought reduces river flow.
    A binational agreement with Mexico requires the United States to 
invest in water conservation, habitat restoration, and scientific 
monitoring projects in the delta and release approximately 2 percent of 
natural flow through 2026. The clam will likely benefit from ongoing 
efforts to conserve other species and their habitats within the greater 
Gulf of California, e.g., the totoaba (Totoaba macdonaldi) and the 
vaquita porpoise (Phocoena sinus). Portions of the species' range occur 
within two protected areas that are part of the UNESCO Biosphere 
Reserve Program and are owned and managed by the Mexican Government.
    In the May 3, 2022, CNOR (87 FR 26152), and again in the June 27, 
2023, CNOR (88 FR 41560), the Colorado Delta clam was assigned an LPN 
of 8. After reevaluating the threats to this species for this CNOR, we 
have determined that no change in its LPN of 8 is warranted. The threat 
of habitat loss and degradation in the Colorado Delta region is 
ongoing. However, this threat appears to be affecting the clam in the 
upper Gulf of California and not throughout remainder of its range. 
Therefore, an LPN of 8 remains valid to reflect imminent threats of 
moderate magnitude.

Petitions To Reclassify Species Already Listed

    We previously made warranted-but-precluded findings on petitions 
seeking to reclassify threatened species to endangered status for delta 
smelt (Hypomesus transpacificus) and northern spotted owl (Strix 
occidentalis caurina). Because these species are already listed under 
the Act, they are not candidates for listing and are not included in 
table 5, below. Below, we provide updated summaries for these species 
previously found to be warranted but precluded for uplisting.
    This document and associated species assessment forms constitute 
the findings for the resubmitted petitions to reclassify the delta 
smelt and northern spotted owl. Summaries of our updated assessments 
for these species are provided below. We find that reclassification to 
endangered status for the delta smelt and northern spotted owl are 
currently warranted but precluded by work identified above (see 
Findings for Petitioned Candidate Species, above). One of the primary 
reasons that the work identified above is considered to have higher 
priority is that these species are currently listed as threatened and, 
therefore, already receive certain protections under the Act. For the 
delta smelt and northern spotted owl, those protections are set forth 
in our regulations at 50 CFR 17.31 and, by reference, 50 CFR 17.21. It 
is therefore unlawful for any person, among other prohibited acts, to 
take (i.e., to harass, harm, pursue, hunt, shoot, wound, kill, trap, 
capture, or collect, or attempt to engage in such activity) a delta 
smelt or northern spotted owl, subject to applicable exceptions.
    Other protections that currently apply to these threatened species 
include those under section 7(a)(2) of the Act, whereby Federal 
agencies must insure

[[Page 48931]]

that any action they authorize, fund, or carry out is not likely to 
jeopardize the continued existence of any endangered or threatened 
species.

Northern Spotted Owl

    The northern spotted owl is the largest of three subspecies of 
spotted owls. The historical range of the northern spotted owl included 
most mature forests or stands throughout the Pacific Northwest, from 
southwestern British Columbia to as far south as Marin County, 
California. The current range of the northern spotted owl is smaller 
than the historical range as the northern spotted owl is extirpated or 
very uncommon in certain areas such as southwestern Washington and 
British Columbia.
    The northern spotted owl is relatively long-lived, has a long 
reproductive life span, invests significantly in parental care, and 
exhibits high adult survivorship relative to other North American owls. 
Nesting and roosting habitat characteristics are usually found in older 
forests and include moderate to high canopy cover; multiple canopy 
layers; large trees with deformities such as large cavities, broken 
tops, or mistletoe infections; large snags and fallen trees; and space 
beneath the canopy for flight. Foraging habitat varies greatly across 
the range, as does diet, and may coincide with or differ from nesting 
and roosting habitat. Landscapes supporting dispersal typically include 
a high proportion of the area in forested cover with trees larger than 
11 inches (28 centimeters) in diameter at breast height and more than 
30 to 40 percent canopy cover. Northern spotted owls can be found in 
younger forest stands that have the structural characteristics of older 
forests or retained structural elements from the previous forest, 
especially in redwood forests and mixed conifer-hardwood forests along 
the coast of northwestern California. We have carefully assessed the 
best scientific and commercial information available regarding the 
past, present, and future threats to the northern spotted owl, and we 
evaluated all relevant factors under the five listing factors, 
including any regulatory mechanisms and conservation measures 
addressing these stressors. The incursion of the nonnative barred owl 
(Strix varia) is currently the stressor with the largest negative 
impact on northern spotted owls.
    On Federal lands, the Northwest Forest Plan has reduced habitat 
loss and allowed for the development of new northern spotted owl 
habitat, and the 2016 revised Resource Management Plans for the Bureau 
of Land Management lands in western Oregon are expected to do the same; 
however, forest ecosystem processes continue to change, and the 
expansion of barred owl populations is altering the capacity of intact 
habitat to support northern spotted owls. Therefore, we find that 
reclassification of the northern spotted owl as an endangered species 
under the Act is warranted.
    Because the northern spotted owl's current classification as 
threatened and the blanket section 4(d) rule that has prescribed 
protections for the species since it was listed (see 50 CFR 17.31(a)) 
already provide the species the full protections afforded by the Act, 
uplisting the species to endangered status would not substantively 
increase protections for the northern spotted owl but would more 
accurately classify the species given its current status. The listing 
priority number for the northern spotted owl is 3, reflecting the high 
magnitude of the threats, which are causing steep population declines. 
It also reflects the immediacy of the threats. Competition with barred 
owls is depressing demographic rates in nearly all populations 
throughout the northern spotted owl's range. Finally, the listing 
priority number reflects the status of the northern spotted owl as a 
subspecies.
    A detailed discussion of the basis for this finding can be found in 
our northern spotted owl species assessment form (see ADDRESSES, 
above), as well as in our 12-month finding published in the Federal 
Register on December 15, 2020 (85 FR 81144), in which we found that 
reclassification of the northern spotted owl from threatened to 
endangered was warranted but precluded by higher-priority actions.

Delta Smelt

    Delta smelt are slender-bodied fish, translucent with a steely blue 
sheen to their sides and are generally about 60 to 70 millimeters (2.36 
to 2.75 inches) long. They consist of a single population that 
primarily occupies open-water habitats in Suisun Bay and marsh and the 
Sacramento-San Joaquin Delta.
    The delta smelt is primarily an annual species, meaning that it 
completes its life cycle in one year. It occupies pelagic, cool, 
turbid, low-salinity and freshwater habitats. It feeds on small, 
planktonic crustaceans, especially calanoid copepods, at all stages of 
its life. Adults spawn on sandy or hard substrate. As a small fish, 
delta smelt shift vertically and longitudinally within the water column 
with the tidal currents to stay where food is available and to 
distribute throughout the delta to spawn. The species needs clean, 
contaminant-free water; abundant zooplankton prey; water channels free 
from invasive vegetation; and hydrologic conditions that place their 
low-salinity habitat in locations that both maximize the volume of 
habitat and minimize the fish's risk of entrainment into both poor 
habitat conditions and water export facilities.
    The primary known threats cited in the April 7, 2010, 12-month 
finding for reclassifying the delta smelt from threatened to endangered 
(75 FR 17667) are entrainment by water export facilities, increases in 
salinity due to reductions in freshwater flow and summer and fall 
increases in water clarity, effects from introduced species, 
contaminant exposure, and small population size. The 2021 California 
Department of Fish and Wildlife and Service adult abundance estimates 
are the lowest ever recorded. Although conservation measures are in 
place to protect the species, including the 2019 biological opinion, 
experimental release, and supplementation, these measures have not been 
sufficient to halt the decline of the species. Therefore, based on a 
review of the best scientific and commercial information available, we 
find that the delta smelt still meets the definition of an endangered 
species under the Act, and that it warrants reclassification from 
threatened to endangered. However, at this time, the promulgation of a 
formal rulemaking to reclassify delta smelt is precluded by higher 
priority actions. Because the delta smelt's current classification as 
threatened and the blanket section 4(d) rule that has prescribed 
protections for the species since it was listed (see 50 CFR 17.31(a)) 
already provide the species the full protections afforded by the Act, 
uplisting the species to endangered status would not substantively 
increase protections for the delta smelt but would more accurately 
classify the species given its current status. In addition, although 
the identified threats are imminent and substantial, emergency 
uplisting would provide no additional benefit to the species.
    In our 12-month finding published in the Federal Register on April 
7, 2010 (75 FR 17667), the delta smelt was assigned an LPN of 2. For 
this update, there is no change in its LPN. The majority of threats 
identified in 2010 remain. Therefore, the LPN is valid for this species 
to reflect imminent threats of moderate magnitude.

Current Notice of Review

    We gather data on plants and animals, both native and foreign to 
the United States, that appear to merit consideration for addition to 
the Lists of

[[Page 48932]]

Endangered and Threatened Wildlife and Plants (Lists). This document 
identifies those species that we currently regard as candidates for 
addition to the Lists. These candidates include species and subspecies 
of fish, wildlife, or plants, and DPSs of vertebrate animals. This 
compilation relies on information from status surveys conducted for 
candidate assessment and on information from Tribes, State Natural 
Heritage Programs, other State and Federal agencies, foreign countries, 
knowledgeable scientists, public and private natural resource 
interests, and comments received in response to previous CNORs.
    Tables 5 and 6, below, list animals arranged alphabetically by 
common names under the major group headings, and list plants 
alphabetically by names of genera, species, and relevant subspecies and 
varieties. Animals are grouped by class or order. Useful synonyms and 
subgeneric scientific names appear in parentheses with the synonyms 
preceded by an ``equals'' sign. We sort plants by scientific name due 
to the inconsistencies in common names, the inclusion of vernacular and 
composite subspecific names, and the fact that many plants still lack a 
standardized common name.
    Table 5 lists all candidate species, plus species currently 
proposed for listing under the Act (as of September 30, 2024). We 
emphasize that in this document that we are not proposing to list any 
of the candidate species; rather, we will develop and publish proposed 
listing rules for these species in the future. We encourage Tribes, 
State agencies, other Federal agencies, foreign countries, and other 
parties to consider these species in environmental planning.
    In table 5, the ``category'' column on the left side of the table 
identifies the status of each species according to the following codes:
    PE--Species proposed for listing as endangered. This category, as 
well as PT and PSAT (below), does not include species for which we have 
withdrawn or finalized the proposed rule.
    PT--Species proposed for listing as threatened.
    PSAT--Species proposed for listing as threatened due to similarity 
of appearance.
    C--Candidates: Species for which we have on file sufficient 
information on biological vulnerability and threats to support 
proposals to list them as endangered or threatened. Issuance of 
proposed rules for these species is precluded at present by other 
higher priority actions. This category includes species for which we 
made a 12-month warranted-but-precluded finding on a petition to list. 
Our analysis for this document included making new findings on all 
petitions for which we previously made ``warranted-but-precluded'' 
findings. We identify the species for which we made a continued 
warranted-but-precluded finding on a resubmitted petition by the code 
``C'' in the category column (see Findings for Petitioned Candidate 
Species, above, for additional information).
    The ``Priority'' column indicates the LPN for each candidate 
species, which we use to determine the most appropriate use of our 
available resources. Lower numbers have higher priority. We assign LPNs 
based on the immediacy and magnitude of threats, as well as on 
taxonomic status. We published a complete description of our listing 
priority system in the Federal Register (48 FR 43098; September 21, 
1983).
    Following the scientific name (third column) and the family 
designation (fourth column) is the common name (fifth column). The 
sixth column provides the known historical range for the species or 
vertebrate population (for vertebrate populations, this is the 
historical range for the entire species or subspecies and not just the 
historical range for the distinct population segment), indicated by 
postal code abbreviations for States and U.S. territories or by country 
for foreign species. Many species no longer occur in all of the areas 
listed.
    Species in table 6 of this document are those species that we 
included either as proposed species or as candidates in the previous 
CNOR (88 FR 41560; June 27, 2023) that are no longer proposed species 
or candidates for listing (as of September 30, 2024). In FY 2023 and FY 
2024 (or after; please see note to table 6, below), we listed 52 
species. The first column indicates the present status of each species, 
using the following codes:
    E--Species we listed as endangered.
    T--Species we listed as threatened.
    SAT--Species we listed as threatened due to similarity of 
appearance.
    Rc--Species we removed from the candidate list or is no longer 
proposed for listing, because currently available information does not 
support a proposed listing.
    Rp--Species we removed from the candidate list or is no longer 
proposed for listing, because we have withdrawn the proposed listing.
    The second column indicates why the species is no longer a 
candidate species or proposed for listing, using the following codes 
(not all of these codes may have been used in this CNOR):
    A--Species that are more abundant or widespread than previously 
believed and species that are not subject to the degree of threats 
sufficient that the species is a candidate for listing (for reasons 
other than that conservation efforts have removed or reduced the 
threats to the species).
    I--Species for which the best available information on biological 
vulnerability and threats is insufficient to support a conclusion that 
the species is an endangered species or a threatened species.
    L--Species we added to the Lists of Endangered and Threatened 
Wildlife and Plants.
    M--Species we mistakenly included as candidates or proposed species 
in the last notice of review.
    N--Species that are not listable entities based on the Act's 
definition of ``species'' and current taxonomic understanding.
    U--Species that are not subject to the degree of threats sufficient 
to warrant issuance of a proposed listing and therefore are not 
candidates for listing, due, in part or totally, to conservation 
efforts that remove or reduce the threats to the species.
    X--Species we believe to be extinct.
    The columns describing scientific name, family, common name, and 
historical range include information as previously described for table 
5.

Request for Information

    We request additional status information that may be available for 
any of the candidate species identified in this CNOR. We will consider 
this information to monitor changes in the status or LPN of candidate 
species and to manage candidates as we prepare listing documents and 
future revisions to the CNOR. We also request information on additional 
species to consider including as candidates as we prepare future 
updates of this CNOR.
    We request you submit any further information on the species named 
in this document as soon as possible or whenever it becomes available. 
We are particularly interested in any information:
    (1) Indicating that we should add a species to the list of 
candidate species;
    (2) Indicating that we should remove a species from candidate 
status;
    (3) Recommending areas that we should designate as critical 
habitat, or indicating that designation of critical habitat would not 
be prudent;
    (4) Documenting threats to any of the included species;
    (5) Describing the immediacy or magnitude of threats facing 
candidate species;

[[Page 48933]]

    (6) Pointing out taxonomic or nomenclature changes for any of the 
species;
    (7) Suggesting appropriate common names; and
    (8) Noting any mistakes, such as errors in the indicated historical 
ranges.
    We will consider all information provided in response to this CNOR 
in deciding whether to propose species for listing and when to 
undertake necessary listing actions (including whether emergency 
listing under section 4(b)(7) of the Act is appropriate).
    Submit information, materials, or comments regarding the species to 
the person identified as having the lead responsibility for the species 
in table 4, below.
