Endangered and Threatened Wildlife
and Plants; Threatened Status for the
Suwannee Alligator Snapping Turtle
with a Section 4(d) Rule
Fish and Wildlife Service,
Interior.
ACTION: Final rule.
AGENCY:
We, the U.S. Fish and
Wildlife Service (Service), determine
threatened species status under the
Endangered Species Act of 1973 (Act),
as amended, for the Suwannee alligator
snapping turtle (Macrochelids
suwanniensis), a large, freshwater turtle
species from the Suwannee River basin
in Florida and Georgia. This rule adds
the species to the List of Endangered
and Threatened Wildlife. We also
finalize a rule issued under the
authority of section 4(d) of the Act that
provides measures that are necessary
and advisable to provide for the
conservation of this species. We have
determined that designating critical
habitat for the Suwannee alligator
snapping turtle is not prudent.
DATES: This rule is effective July 29,
2024.
SUMMARY:
This final rule is available
on the internet at https://
www.regulations.gov under Docket No.

SUPPLEMENTARY INFORMATION:
Executive Summary
Why we need to publish a rule. Under
the Act, a species warrants listing if it
meets the definition of an endangered
species (in danger of extinction
throughout all or a significant portion of
its range) or a threatened species (likely
to become an endangered species within
the foreseeable future throughout all or
a significant portion of its range). If we
determine that a species warrants
listing, we must list the species
promptly and designate the species’
critical habitat to the maximum extent
prudent and determinable.We have
determined that the Suwannee alligator
snapping turtle meets the Act’s
definition of a threatened species;
therefore, we are listing it as such.
Listing a species as an endangered or
threatened species can be completed
only by issuing a rule through the
Administrative Procedure Act
rulemaking process (5 U.S.C. 551 et
seq.).
What this document does. This rule
lists the Suwannee alligator snapping
turtle (Macrochelys suwanniensis) as a
threatened species and finalizes the rule
issued under the authority of section
4(d) of the Act (the ‘‘4(d) rule’’) that
provides measures that are necessary
and advisable to provide for the
conservation of this species.
The basis for our action. Under the
Act, we may determine that a species is
an endangered or threatened species
based on any of five factors: (A) The
present or threatened destruction,
modification, or curtailment of its
habitat or range; (B) overutilization for
commercial, recreational, scientific, or
educational purposes; (C) disease or
predation; (D) the inadequacy of
existing regulatory mechanisms; or (E)
other natural or manmade factors

affecting its continued existence. We
have determined that the primary
threats acting on the Suwannee alligator
snapping turtle include illegal harvest
and collection (Factor B), nest predation
(Factor C), and hook ingestion and
entanglement due to bycatch associated
with freshwater fishing (Factor E).
Previous Federal Actions
Please refer to the April 7, 2021,
proposed rule (86 FR 18014) for a
detailed description of previous Federal
actions concerning the Suwannee
alligator snapping turtle.
Peer Review
A species status assessment (SSA)
team prepared an SSA report, version
1.0, for the Suwannee alligator snapping
turtle (Service 2020, entire). The SSA
team was composed of Service
biologists, in consultation with other
species experts. The SSA report
represents a compilation of the best
scientific and commercial data available
concerning the status of the species,
including the impacts of past, present,
and future factors (both negative and
beneficial) affecting the species.
In accordance with our joint policy on
peer review published in the Federal
Register on July 1, 1994 (59 FR 34270),
and our August 22, 2016, memorandum
updating and clarifying the role of peer
review of listing actions under the Act,
we sought peer review of the SSA report
version 1.0 (Service 2020, entire). As
discussed in the proposed rule, we sent
the SSA report to four independent peer
reviewers and received responses from
one reviewer. The peer review can be
viewed at https://www.regulations.gov
and at our Florida Ecological Services
Field Office (see FOR FURTHER
INFORMATION CONTACT). In preparing the
proposed rule, we incorporated the
results of this review, as appropriate,
into the SSA report, which was the
foundation for the proposed rule and
this final rule. A summary of the peer
review comments and our responses can
be found in in the Summary of
Comments and Recommendations
below.
Summary of Changes From the
Proposed Rule
In preparing this final rule, we
reviewed and fully considered
comments we received on our April 7,
2021, proposed rule to list the
Suwannee alligator snapping turtle as a
threatened species with a 4(d) rule. We
updated the Suwannee alligator
snapping turtle SSA report (to version
1.2 (Service 2022, entire) based on
comments and additional information
provided during the proposed rule’s
E:\FR\FM\27JNR1.SGM
27JNR1
lotter on DSK11XQN23PROD with RULES1
53508
Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
comment period. Those updates are
reflected in this final rule, as follows:
1. We update the description of the
species’ representation and redundancy
and clarify these conservation
principles to provide a better
understanding of the species’ current
and future viability.
2. We include new information
provided during the comment period
regarding the effectiveness of best
management practices (BMPs)
associated with forest management
practices. We added a discussion on
ways in which the implementation of
such BMPs provides conservation
benefits to the species.
3. For the 4(d) rule, we are not
including the exception from
prohibitions associated with Federal
and State captive-breeding programs to
support conservation efforts for wild
populations. We determined this
provision is redundant with the
exception under 50 CFR 17.31(b), which
is already included in the 4(d) rule.
4. For the 4(d) rule, we are not
including the exception from the
prohibitions regarding incidental take
resulting from herbicide/pesticide use
from this final rule. We do not have
enough information about the types or
amounts of pesticides that may be
applied in areas where Suwannee
alligator snapping turtle occurs to be
able assess the future impacts to the
species. The additional materials
provided during the public comment
period indicate impacts to other turtle
species from pesticide use occurs
(Bishop et al. 1991, entire; Sparling et
al. 2006, entire; Kittle et al. 2018,
entire). Therefore, including this
exception to incidental take may not
provide for the conservation of the
species. Further, we note that the
Environmental Protection Agency (EPA)
has not consulted on most pesticide
registrations to date, so excepting take
solely based on user compliance with
label directions and State and local
regulations EPA has not consulted on
most pesticide registrations to date and
is not appropriate in this situation.
Retaining this exception in the absence
of consultation on a specific pesticide
registration may create confusion
regarding the consideration of these
impacts and whether Federal regulatory
processes apply to these activities. It
was not our intent to supersede the
consultation on the pesticide
registration nor other Federal activities.
5. For the 4(d) rule, we revise the text
of the exception from incidental take
prohibition resulting from forestry
management practices. We remove the
terms ‘‘silviculture and silvicultural
practices’’ and replace them with ‘‘forest
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
management practices’’ to clarify the
exception to incidental take
prohibitions, as this is more appropriate
for the intent and purpose of the rule.
6. For the 4(d) rule, we are not
including the exception from incidental
take prohibition resulting from
construction, operation, and
maintenance activities that occur near
and in a stream. We determined this
exception is too vague to meaningfully
provide conservation benefits to the
species. In addition, this exception
could have caused confusion regarding
whether Federal or State regulatory
processes apply to these activities.
Many activities occurring near or in a
stream require permits or project review
by Federal or State agencies, and
including this exception could have
been interpreted as removing these
requirements, which was not our
intention.
7. For the 4(d) rule, we are not
including the exception from incidental
take prohibition resulting from
maintenance dredging activities that
occur in the previously disturbed
portion of a maintained channel. We
determined this exception is too vague
to meaningfully provide conservation
benefits to the species. In addition,
dredging activities to promote river
traffic can cause temporary turbidity,
leading to decreased ability to see and
ambush prey species; the removal of
underwater snags, which could reduce
prey availability by eliminating areas
where prey is found (e.g., congregation
areas, nursery areas, feeding areas); and
the filling of scour areas used to ambush
prey. In addition, this exception could
have caused confusion regarding
whether Federal or State regulatory
processes apply to these activities. All
in-water work, including dredging in
previously dredged area, requires
appropriate State and Federal permits,
so including this exception could have
been interpreted as removing this
requirement, which was not our
intention.
8. For the 4(d) rule, we are not
including the exception from
prohibitions for Tribal employees and
State-licensed wildlife rehabilitation
facilities. A provision under 50 CFR
17.31(b)(1) now extends to federally
recognized Tribes the exceptions to
prohibitions for threatened wildlife to
aid, salvage, or dispose of threatened
wildlife and is already included in this
4(d) rule. We also are not including the
exception from prohibitions for Statelicensed wildlife rehabilitation facilities
because it is redundant with the
provision at 50 CFR 17.21(c)(3), which
allows take of endangered wildlife
without a permit if such action is
PO 00000
Frm 00028
Fmt 4700
Sfmt 4700
necessary to aid a sick, injured, or
orphaned specimen without additional
authorization, which is also already
included in the 4(d) rule.
9. We update information to reflect
that the alligator snapping turtle
(Macrochelys temminckii) was
transferred from Appendix III of CITES
to Appendix II (CITES 2023, pp. 45–46).
10. We make minor, nonsubstantive
editorial corrections and revisions for
clarity and consistency throughout this
document.
The information we received during
the comment period on our April 7,
2021, proposed rule did not change our
determination that the Suwannee
alligator snapping turtle meets the Act’s
definition of a threatened species. The
information provided through the
comment period also did not cause us
to revise our determination that
designation of critical habitat for the
Suwannee alligator snapping turtle is
not prudent.
Summary of Comments and
Recommendations
In the proposed rule published on
April 7, 2021 (86 FR 18014), we
requested that all interested parties
submit written comments on the
proposal by June 7, 2021. We also
contacted appropriate Federal and State
agencies, scientific experts and
organizations, and other interested
parties and invited them to comment on
the proposed listing determination and
proposed 4(d) rule. A newspaper notice
inviting general public comment was
published in the Gainesville Sun on
April 21, 2021. We did not receive any
requests for a public hearing. All
substantive information provided
during the comment period either has
been incorporated directly into the final
rule or is addressed below.
As discussed in Peer Review above,
we received a response from one peer
reviewer on the draft SSA report. As
discussed above, because we conducted
this peer review prior to the publication
of our proposed rule, we had already
incorporated all applicable peer review
comments into version 1.1 of the SSA
report, which was the foundation for the
proposed rule and this final rule and
ultimately into the latest version of the
SSA report, version 1.2 (Service 2022,
entire). The peer reviewer generally
concurred with our methods and
conclusions and provided additional
information regarding seed dispersal by
the common snapping turtle (Chelydra
sepentina). We added the information
provided by the peer reviewer into the
SSA report, version 1.1 (Service 2021,
entire) as appropriate.

Public Comments
We received 34 public comments in
response to our April 7, 2021, proposed
rule. We reviewed all comments we
received during the public comment
period for substantive issues and new
information regarding the proposed
rule. Seventeen comments provided
substantive comments or new
information concerning the proposed
listing of the species’ status, proposed
4(d) rule, and prudency determination
for critical habitat for the Suwannee
alligator snapping turtle. Below, we
provide a summary of public comments
we received; however, comments that
we incorporated as changes into the
final rule, comments outside the scope
of the proposed rule, and those without
supporting information did not warrant
an explicit response and, thus, are not
presented here. Identical or similar
comments have been consolidated and a
single response provided.

Comments From States
(1) Comment: The Georgia
Department of Natural Resources
(GDNR), Wildlife Resources Division
commented that occasional observations
by biologists and anglers indicate that
ensnarement and/or hook ingestion by
Suwannee alligator snapping turtle may
occur as a result of legal fishing
methods in Georgia, and research is
needed to further quantify population
impacts of incidental take on this
species. The GDNR also recommended
the rule place greater emphasis on
promoting practices and regulations to
reduce impacts to the Suwannee
alligator snapping turtle from
abandoned fishing gear.
Our Response: We plan to work with
both GDNR and the Florida Fish and
Wildlife Conservation Commission
(FWC) to better understand impacts
from legal and abandoned fishing gear.
As discussed in our April 7, 2021,
proposed rule, turtle bycatch from legal
recreational and commercial fishing
with hoop nets and trot lines (and
varieties including jug lines, bush
hooks, and limb lines) is a concern for
the conservation of the species due to its
effects on species abundance,
particularly in light of the species’ lifehistory traits. It is important to ensure
that fishing activities take into
consideration the need to prevent
accidental turtle deaths from the use of
such fishing gear, and we will work
with our State partners to identify
measures and revisions to existing State
fishing regulations to reduce bycatch of
Suwannee alligator snapping turtle.
Given we did not receive information
during the comment period for bycatch
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
reduction techniques, we did not
include an exception for incidental take
of the Suwannee alligator snapping
turtle resulting from bycatch from
otherwise lawful recreational and
commercial fishing in our final 4(d)
rule. Therefore, take of the species
resulting from bycatch activities is
prohibited in the 4(d) rule.
Public Comments Categorized by Topic
Species’ Status
(2) Comment: One commenter stated
their view that the Suwannee alligator
snapping turtle should be listed as an
endangered species rather than a
threatened species.
Our Response: An endangered species
is one that is in danger of extinction
throughout all or a significant portion of
its range. Based on the best available
information as described in the SSA
report (Service 2022, entire), we do not
find that the Suwannee alligator
snapping turtle is currently in danger of
extinction throughout all or a significant
portion of its range. The current
condition of the species provides for
sufficient resiliency, redundancy, and
representation such that it is not
currently in danger of extinction (see
Determination of Suwannee Alligator
Snapping Turtle Status in the proposed
listing rule (86 FR 18014, April 7, 2021,
at pp. 18026–18028) and below in this
final rule). When evaluating the species’
status based on the threats and the
species’ response to the threats in the
future, the species meets the Act’s
definition of a threatened species
because it is at risk of becoming an
endangered species within the
foreseeable future throughout all of its
range. The commenters did not provide
any new information regarding threats
to the Suwannee alligator snapping
turtle or its current status that was not
already considered in the SSA report
(Service 2021, entire) or our April 7,
2021, proposed rule. With no new
information to consider, our conclusion
regarding the status of the Suwannee
alligator snapping turtle remains the
same.
(3) Comment: A commenter suggested
we list the common snapping turtle (C.
serpentina) under the Act based on
similarity of appearance (see 16 U.S.C.
1533(e)) to help curb the threat of
incidental captures of Suwannee
alligator snapping turtles by trappers
that are targeting common snapping
turtles.
Our Response: Under section 4(e) of
the Act (16 U.S.C. 1533(e)), a species
may be listed as endangered or
threatened due to similarity of
appearance of a listed species if the
PO 00000
Frm 00029
Fmt 4700
Sfmt 4700
53509
species so closely resemble one another
that it is difficult to tell them apart and
if this similarity is a threat to the species
that is warranted for listing. The
likelihood of incidental capture from
legal common snapping turtle harvest is
anticipated to be low due to the
disparity between the preferred habitat
types used by the common snapping
turtle and the Suwannee alligator
snapping turtle. Common snapping
turtle habitat typically includes
impoundments such as lakes, ponds,
and oxbows. The Suwannee alligator
snapping turtle prefers more riverine
systems. While there may be some
overlap between these habitat types and
their ranges, the Suwannee alligator
snapping turtle can be distinguished
from the common snapping turtle based
on certain physical characteristics. The
common snapping turtle shares some
similar features to the Suwannee
alligator snapping turtle, but there are
distinctive characteristics that can aid in
differentiation of the two species. The
Suwannee alligator snapping turtle’s
carapace has three keeled ridges and a
curved, hooked, beak-like projection at
the mouth, while the common snapping
turtle lacks these features. Because of
the physical characteristics that are
unique to each species that facilitate
identification, we have determined that
listing the common snapping turtle due
to similarity of appearance is not
necessary or appropriate.
(4) Comment: One commenter noted
the Service’s analysis of redundancy
and representation for the Suwannee
alligator snapping turtle in the SSA
report was contrary to the agency’s SSA
framework and commented that we did
not describe representation in a
meaningful way.
Our Response: Our analysis of the
Suwannee alligator snapping turtle’s
redundancy and representation adheres
to the definitions presented in the SSA
framework. Representation is the ability
of the species to adapt to both near-term
and long-term changes in its physical
and biological environment, and
redundancy is the ability of the species
to withstand catastrophic events. At the
time of our April 7, 2021, proposed rule,
the best available scientific information
regarding the Suwannee alligator
snapping turtle indicated there was no
genetic or environmental condition
variation across the species’ range. We
assessed representation, which
measures a species’ adaptive potential
in the face of natural or anthropogenic
changes, as inherently low for this
species, because the best available
information at that time showed it
lacked significant genetic variation
within its single population. Based on
E:\FR\FM\27JNR1.SGM

53510
Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
lotter on DSK11XQN23PROD with RULES1
the public comments and new literature
related to assessing adaptive capacity
(Thurman et al. 2020, entire), in this
final rule and our revised SSA report,
version 1.2 (Service 2022, entire), we
updated our discussion of
representation by describing the
Suwannee alligator snapping turtle’s
adaptive capacity in terms of its genetic,
biological, and ecological traits
necessary to understand the species’
plasticity to changing conditions over
time. Adaptive capacity reflects the
amount of tolerance for change based on
genotypic and phenotypic attributes.
Change can include impacts from
climate change (e.g., higher air and
water temperatures, saltwater intrusion,
etc.) and humans (e.g., water
withdrawal, fishing gear, habitat
alterations, etc.). We assessed the
Suwannee alligator snapping turtle to
have low to moderate adaptive capacity
in the life-history and demography traits
and moderate to high adaptive capacity
in the distribution, movement,
evolutionary potential, ecological role,
and abiotic niche traits. Further
information on how we describe the
species in terms of its adaptive capacity
with its ability to acclimate to
environmental stressors can be found in
our SSA report, version 1.2 (Service
2022, pp. 37–39).
For redundancy, in our proposed and
this final rule, we assessed current
redundancy as limited, as the species is
considered a single population with no
physical barriers to movement. While
there is only a single population, it is
widely distributed across the historical
range. We assessed the chance of a
catastrophic event affecting the entire
species as very low. However, given the
Suwannee alligator snapping turtle is
currently assessed as a single
population with an estimated
abundance of 2,000 turtles across the
species’ historical range, we determined
redundancy to be naturally limited,
given the species’ distribution is limited
to the Suwannee River basin.
4(d) Rule
(5) Comment: One commenter
inquired why the Service did not apply
the blanket 4(d) rule to this species.
Our Response: Prior to August 27,
2019, the prohibitions for endangered
species under section 9 of the Act were
generally extended to threatened species
(referred to as the ‘‘blanket 4(d) rule’’)
unless we adopted a species-specific
4(d) rule for a particular species. On
August 27, 2019, we published a final
rule (84 FR 44753) removing the blanket
4(d) rule for threatened species. That
2019 final rule was in effect when we
published our April 7, 2021, proposed
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
rule for the Suwannee alligator
snapping turtle and is still in effect. On
May 6, 2024, a rule became effective
that re-instated the blanket 4(d) rule (89
FR 23919). The updated regulations
extend the majority of the protections
(all of the prohibitions that apply to
endangered species under section 9
with certain exceptions to those
prohibitions) to threatened species,
unless we issue an alternative rule
under section 4(d) of the Act for a
particular species (i.e., a species-specific
4(d) rule). For species with a speciesspecific 4(d) rule, that rule contains all
of the protective regulations for that
species. We exercised our authority
under section 4(d) of the Act and
developed a proposed species-specific
4(d) rule to address the specific threats
and conservation needs of the
Suwannee alligator snapping turtle. The
4(d) rule is necessary and advisable to
provide for the conservation of the
Suwannee alligator snapping turtle. For
the species-specific 4(d) rule, we
determined that it is not necessary to
apply all of the Act’s section 9
prohibitions to the Suwannee alligator
snapping turtle; the provisions of the
species-specific 4(d) rule are described
below under Provisions of the 4(d) Rule
and set forth below under Regulation
Promulgation.
(6) Comment: One commenter
expressed concern that the Service’s
description of the exceptions for
construction, operation, and
maintenance in the 4(d) rule is too
broad and vague to determine when the
exception applies.
Our Response: We agree that it is
difficult to understand and identify
specific situations when the exception
to incidental take resulting for
construction, operation, and
maintenance activities would apply.
Accordingly, as stated above under
Summary of Changes from the Proposed
Rule, we are not including an exception
to the incidental take prohibitions in the
4(d) rule for the Suwannee alligator
snapping turtle because it is too vague
to meaningfully provide conservation
benefits to the species. In addition,
many activities occurring near or in a
stream require permits or project review
by Federal or State agencies, and, if
retained, this exception would have
caused confusion with respect to the
requirements that must be met when
undertaking these activities.
(7) Comment: One commenter
expressed concern about an exception
for silviculture and forestry BMPs, given
the implementation of less effective
silviculture and forestry BMPs for
riparian areas and potential negative
impacts to the species.
PO 00000
Frm 00030
Fmt 4700
Sfmt 4700
Our Response: State-approved BMPs
for silviculture and forestry maintain
riparian buffers, resulting in reduced
sedimentation into the stream from
upland sources, reduced water
temperature, increased dissolved
oxygen, and more material for in-water
woody debris. These attributes promote
aquatic diversity and are required for
healthy habitats.
Implementing BMPs that avoid or
minimize the effects of habitat
alterations in areas that support
Suwannee alligator snapping turtles will
provide additional measures for
conserving the species by reducing
indirect effects to the species. We
recognize that silvicultural operations
are widely implemented in accordance
with State-approved forestry BMPs (as
reviewed by Cristan et al. 2018, entire),
which provide more stringent riparian
protections, and the adherence to these
BMPs broadly protects water quality,
particularly related to sedimentation (as
reviewed by Cristan et al. 2016, entire;
Warrington et al. 2017, entire; and
Schilling et al. 2021, entire). For
example, Florida’s State silviculture
BMPs for designated outstanding
Florida waters, such as the Suwannee
and Santa Fe Rivers, require a 300-foot
buffer on each side of the river. Forestry
and silvicultural activities that
implement State-approved BMPs will
have a de minimis impact on the
species, and we have determined that
this exception to the incidental take
prohibitions in the 4(d) rule will be
beneficial to the species. If forestry and
silvicultural activities do not implement
or improperly implement BMPs, then
this exception will not apply.
(8) Comment: One commenter
suggested that current regulatory
mechanisms are inadequate to address
the threat of incidental bycatch to the
Suwannee alligator snapping turtle, and
a 4(d) rule that excepts take incidental
to recreational fishing activities would
only be appropriate if the methods of
fishing that incidentally capture turtles
were prohibited or significantly
modified to prevent incidental capture.
Our Response: In the proposed rule,
we requested information regarding
ideas for the design of a turtle escape or
exclusion device and modified trot line
techniques that would effectively
eliminate or significantly reduce
bycatch of alligator snapping turtles
from recreational fishing; however, we
did not receive any comments to inform
fishing gear modifications to reduce
bycatch of Suwannee alligator snapping
turtles. Recreational fishing activities
are regulated by State natural resource
and fish and game agencies, and these
agencies issue permits for these

activities in accordance with their
regulations. We will coordinate with
State agencies to better understand the
impacts of permitted recreational
fishing on Suwannee alligator snapping
turtles. In addition, we will work with
the State to reduce the risk of bycatch,
which may include modifying fishing
mechanisms based on the best available
science related to reducing fishing
impacts through research and
development on innovative fishing
technologies and methodologies.
Additionally, we will continue
coordinating with State agencies on the
development of public awareness
programs regarding identification and
conservation of the Suwannee alligator
snapping turtle. Further, since we did
not receive information during the
comment period for bycatch reduction
techniques, we do not include in the
4(d) rule an exception to incidental take
of the Suwannee alligator snapping
turtle resulting from bycatch from
otherwise lawful recreational and
commercial fishing using techniques to
reduce bycatch. Therefore, take of the
species resulting from bycatch is
prohibited by the 4(d) rule.
(9) Comment: One commenter
expressed concern about the 4(d) rule’s
exception to the take prohibition for
pesticide and herbicide use. The
commenter stated that the exception is
arbitrary and not supported by the best
available scientific and commercial
data. The commenter stated that
exposure to pesticides and herbicides is
harmful to turtle species and provided
several citations to support the
comment (such as, Bishop et al. 1991,
entire; Sparling et al. 2006, entire; Kittle
et al. 2018, entire))
Our Response: After review of the
comments to the proposed rule and
revisiting the best available scientific
and commercial information, we are not
including the pesticide and herbicide
use exception from the incidental take
prohibitions in the final 4(d) rule. In the
proposed rule and this final rule, we
describe the primary threats to the
Suwannee alligator snapping turtle as
illegal harvest and collection, nest
predation, and hook ingestion and
entanglement due to bycatch associated
with freshwater fishing. And although
nest predation is a primary threat to the
species, the most common nest
predators identified are raccoons
(Procyon lotor). Nonnative, invasive
species, such as feral pigs (Sus scrofa)
and red imported fire ants (Solenopsis
invicta), occur across the species’ range,
but to date, nest predation by these
nonnative species has not been
documented. In the preamble of our
proposed 4(d) rule, we proposed an
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
exception to incidental take
prohibitions resulting from invasive
species removal activities using
pesticides and herbicides as these types
of activities could be considered
beneficial to the native ecosystem and
are likely to improve habitat conditions
for the species. However, we do not
have enough information about the
types or amounts of pesticides that may
be applied in areas where Suwannee
alligator snapping turtle occurs to be
able assess the future impacts to the
species.
The additional materials provided
during the public comment period do
not indicate Suwannee alligator
snapping turtle is impacted greatly from
pesticides used to reduce impacts from
nonnative, invasive species; however,
the information provided does indicate
impacts to other turtle species from
pesticide use (Bishop et al. 1991, entire;
Sparling et al. 2006, entire; Kittle et al.
2018, entire). As documented in other
turtle species from the literature
provided by the commenter, we
assessed that there is the potential of
indirect effects from pesticides on the
Suwannee alligator snapping turtle, and
therefore, including this exception to
incidental take may not provide for the
conservation of the species.
Further, we note that the
Environmental Protection Agency (EPA)
has not consulted on most pesticide
registrations to date, so excepting take
solely based on users complying with
labels is not appropriate in this
situation. Thus, we are not including
the exception from the prohibitions
regarding incidental take resulting from
herbicide/pesticide use from this final
rule.
(10) Comment: One commenter
suggested modifying the 4(d) rule to
except captive breeding for turtles held
in captivity prior to the effective date of
the listing to allow for appropriate
captive-breeding programs to contribute
to the conservation of the species.
Our Response: We recognize the
contribution of permitted captive
breeding to the conservation of species.
However, there are currently no captivebreeding efforts occurring for the
Suwannee alligator snapping turtle;
therefore, there are no existing captivebreeding programs that we could except
prior to the effective date of this final
rule (see DATES, above). There are
programs underway for M. temminckii
that include captive rearing, head-start
programs, and reintroductions that are
successful. Similar programs may be
implemented in the future to conserve
the Suwannee alligator snapping turtle.
In our proposed 4(d) rule, we included
a provision allowing incidental take
PO 00000
Frm 00031
Fmt 4700
Sfmt 4700
53511
associated with Federal and State
captive-breeding programs to support
conservation efforts for wild
populations. However, we determined
this provision is duplicative of an
exception under 50 CFR 17.31(b), which
we also included in the proposed 4(d)
rule and retain in this final 4(d) rule.
Therefore, this final 4(d) rule does not
include a separate captive-breeding
exception from the incidental take
prohibitions.
Critical Habitat
(11) Comment: A commenter claimed
that the Service did not provide
sufficient support for the not-prudent
finding for critical habitat designation
regarding the threat of illegal collection
of the Suwannee alligator snapping
turtle. The commenter also indicates the
location data and maps are already
available to the public in published
reports.
Our Response: We recognize that
designation of critical habitat can
provide benefits to listed species;
however, for the Suwannee alligator
snapping turtle, increased threats
caused by the designation outweigh the
benefits (for further discussion, see 86
FR 18014, April 7, 2021, at p. 18032).
We do not dispute the claim that
publicly available reports identify
specific location data for the species,
including locations of where the species
occurs from trapping efforts. We
acknowledge that general location
information is provided within the
proposed rule and this final rule, and
some specific location information can
be found through other sources.
However, because the critical habitat
designation process includes identifying
the physical or biological features for
the species and specific areas occupied
by the species, the designation of
critical habitat would describe and
disclose areas of higher quality habitat
that supports more turtles, which may
allow collectors to better focus their
efforts in these areas, thereby
exacerbating the threat of collection or
other harm from humans.
I. Final Listing Determination
Background
Please refer to the April 7, 2021,
proposed rule (86 FR 18014) and the
SSA report, version 1.2 (Service 2022,
pp. 4–14) for a full summary of species’
information. Both are available on our
ECOS website for the species at https://

Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
the Suwannee alligator snapping turtle
(Macrochelys suwanniensis) is
presented in the SSA report version 1.2
(Service 2022, pp. 13–22); however,
much of this information is based on the
Macrochelys genus as a whole and
describes the Suwannee alligator
snapping turtle using the best available
information.
Turtles in the genus Macrochelys are
the largest species of freshwater turtle in
North America, are highly aquatic, and
are somewhat secretive. The genus
includes two distinct species, M.
temminckii and M. suwanniensis.
Macrochelys turtles are characterized as
having a large head, long tail, and an
upper jaw with a strongly hooked beak.
They have three raised keels with
posterior elevations on the scutes of the
carapace (upper shell), which is dark
brown and often has algal growth that
adds to their camouflage. Their eyes are
positioned on the side of the head and
are surrounded by small, fleshy, pointed
projections that are unique to the genus.
Suwannee alligator snapping turtles
are primarily freshwater turtles endemic
to the Suwannee River basin and found
more abundantly in the middle reaches
of the Suwannee River where freshwater
springs contribute to an increase in
productivity of the aquatic system (Enge
et al. 2014, p. 36). These turtles are
typically bottom-dwelling, but surface
periodically to breathe (Thomas 2014, p.
60). While the species is typically found
in fresh water, it can tolerate some
salinity and brackish waters, as
barnacles have been found on the
carapace of some turtles. The species is
found in a variety of habitats across its
range, but all life stages rely on
submerged material (i.e., deadhead logs
and vegetation) as important structure
for resting, foraging, and cover from
predators (Enge et al. 2014, p. 39).
The Suwannee River basin
encompasses parts of southern Georgia
and northern Florida. Main water bodies
that currently or historically supported
the Suwannee alligator snapping turtle
include the Suwannee River, Santa Fe
River, New River, Alapaha River, Little
River, and Withlacoochee River.
Individuals occupy main river channels
and tributaries where habitat is present.
Throughout this document, we
provide descriptions of the Suwannee
alligator snapping turtle where the
information is available specific to the
species. We describe the Suwannee
alligator snapping turtle as Macrochelys
suwanniensis or Suwannee alligator
snapping turtle. We reference
Macrochelys when describing the genus
and Macrochelys temminckii
(abbreviated as M. temminckii) when
referring to the second species of the
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
genus, alligator snapping turtle. Since
the taxonomic distinction of the two
Macrochelys spp. is relatively recent, we
may refer to the genus, or alligator
snapping turtles in general, to describe
life-history traits.
The general life stages of Macrochelys
spp. can be described as egg, hatchling
(first year), juvenile (second year until
age of sexual maturity), and adult (age
of sexual maturity through death). Each
life stage has specific requirements in
order to contribute to the productivity of
the next life stage. They excavate nests
in sandy soils or other dry substrate
near freshwater sources that are within
8 to 656 feet (ft) (2.5 to 200 meters (m))
from the shore. The incubation period
for Suwannee alligator snapping turtle
is between 105 to 110 days (Ernst and
Lovich 2009, p. 145).
Males achieve sexual maturity in 11–
21 years and females in 13–21 years
(Ernst and Lovich 2009, p. 144; Reed et
al. 2002, p. 4). The age of sexual
maturity can be influenced by the size
of the turtle, as size increases are greater
when food resources and other
environmental conditions are more
favorable. Adult Suwannee alligator
snapping turtles require streams and
rivers with submerged logs and
undercut banks, clean water, and ample
prey.
Female alligator snapping turtles may
produce a single clutch once a year or
every other year at most even if the
conditions are good (Reed et al. 2002, p.
4). Clutch size may vary across the
species’ range to between 9 and 61 eggs,
with a mean clutch size of 27 eggs (Ernst
and Lovich 2009, p. 145). Most nesting
occurs from May to July (Reed et al.
2002, p. 4).
Suwannee alligator snapping turtles
are long-lived species; provided suitable
conditions, adults can reach carapace
lengths of up to 29 inches and 249
pounds for males, while females can
reach lengths of 22 inches and 62
pounds. The oldest documented
Macrochelys turtle in captivity survived
to at least 80 years of age, but in the
wild, the species may live longer (Ernst
and Lovich 2009, p. 147). The
generation time for the species is around
31 years (range = 28.6–34.0 years, 95
percent confidence interval, Folt et al.
2016, p. 27).
Regulatory and Analytical Framework
Regulatory Framework
Section 4 of the Act (16 U.S.C. 1533)
and the implementing regulations in
title 50 of the Code of Federal
Regulations set forth the procedures for
determining whether a species is an
endangered species or a threatened
PO 00000
Frm 00032
Fmt 4700
Sfmt 4700
species, issuing protective regulations
for threatened species, and designating
critical habitat for endangered and
threatened species. On April 5, 2024,
jointly with the National Marine
Fisheries Service, the Service issued a
final rule that revised the regulations in
50 CFR part 424 regarding how we add,
remove, and reclassify endangered and
threatened species and what criteria we
apply when designating listed species’
critical habitat (89 FR 24300). On the
same day, the Service published a final
rule revising our protections for
endangered species and threatened
species at 50 CFR part 17 (89 FR 23919).
These final rules are now in effect and
are incorporated into the current
regulations. Our analysis for this final
decision applied our current
regulations. Given that we proposed
listing for this species under our prior
regulations (revised in 2019), we have
also undertaken an analysis of whether
our decision would be different if we
had continued to apply the 2019
regulations; we concluded that the
decision would be the same. The
analyses under both the regulations
currently in effect as of May 6, 2024,
and the 2019 regulations are available
on https://www.regulations.gov.
The Act defines an ‘‘endangered
species’’ as a species that is in danger
of extinction throughout all or a
significant portion of its range, and a
‘‘threatened species’’ as a species that is
likely to become an endangered species
within the foreseeable future throughout
all or a significant portion of its range.
The Act requires that we determine
whether any species is an endangered
species or a threatened species because
of any of the following factors:
(A) The present or threatened
destruction, modification, or
curtailment of its habitat or range;
(B) Overutilization for commercial,
recreational, scientific, or educational
purposes;
(C) Disease or predation;
(D) The inadequacy of existing
regulatory mechanisms; or
(E) Other natural or manmade factors
affecting its continued existence.
These factors represent broad
categories of natural or human-caused
actions or conditions that could have an
effect on a species’ continued existence.
In evaluating these actions and
conditions, we look for those that may
have a negative effect on individuals of
the species, as well as other actions or
conditions that may ameliorate any
negative effects or may have positive
effects.
We use the term ‘‘threat’’ to refer in
general to actions or conditions that are
known to or are reasonably likely to
E:\FR\FM\27JNR1.SGM
27JNR1
lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
negatively affect individuals of a
species. The term ‘‘threat’’ includes
actions or conditions that have a direct
impact on individuals (direct impacts),
as well as those that affect individuals
through alteration of their habitat or
required resources (stressors). The term
‘‘threat’’ may encompass—either
together or separately—the source of the
action or condition or the action or
condition itself.
However, the mere identification of
any threat(s) does not necessarily mean
that the species meets the statutory
definition of an ‘‘endangered species’’ or
a ‘‘threatened species.’’ In determining
whether a species meets either
definition, we must evaluate all
identified threats by considering the
species’ expected response and the
effects of the threats—in light of those
actions and conditions that will
ameliorate the threats—on an
individual, population, and species
level. We evaluate each threat and its
expected effects on the species, then
analyze the cumulative effect of all of
the threats on the species as a whole.
We also consider the cumulative effect
of the threats in light of those actions
and conditions that will have positive
effects on the species, such as any
existing regulatory mechanisms or
conservation efforts. The Secretary
determines whether the species meets
the definition of an ‘‘endangered
species’’ or a ‘‘threatened species’’ only
after conducting this cumulative
analysis and describing the expected
effect on the species now and in the
foreseeable future.
The Act does not define the term
‘‘foreseeable future,’’ which appears in
the statutory definition of ‘‘threatened
species.’’ Our implementing regulations
at 50 CFR 424.11(d) set forth a
framework for evaluating the foreseeable
future on a case-by-case basis which is
further described in the 2009
Memorandum Opinion on the
foreseeable future from the Department
of the Interior, Office of the Solicitor
(M–37021, January 16, 2009; ‘‘MOpinion,’’ available online at https://
www.doi.gov/sites/
doi.opengov.ibmcloud.com/files/
uploads/M-37021.pdf). The foreseeable
future extends as far into the future as
the U.S. Fish and Wildlife Service and
National Marine Fisheries Service
(hereafter, the Services) can make
reasonably reliable predictions about
the threats to the species and the
species’ responses to those threats. We
need not identify the foreseeable future
in terms of a specific period of time. We
will describe the foreseeable future on a
case-by-case basis, using the best
available data and taking into account
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
considerations such as the species’ lifehistory characteristics, threat-projection
timeframes, and environmental
variability. In other words, the
foreseeable future is the period of time
over which we can make reasonably
reliable predictions. ‘‘Reliable’’ does not
mean ‘‘certain’’; it means sufficient to
provide a reasonable degree of
confidence in the prediction, in light of
the conservation purposes of the Act.
Analytical Framework
The SSA report documents the results
of our comprehensive biological review
of the best scientific and commercial
data regarding the status of the species,
including an assessment of the potential
threats to the species. The SSA report
does not represent our decision on
whether the species should be listed as
an endangered or threatened species
under the Act. However, it does provide
the scientific basis that informs our
regulatory decisions, which involve the
further application of standards within
the Act and its implementing
regulations and policies.
To assess Suwannee alligator
snapping turtle’s viability, we used the
three conservation biology principles of
resiliency, redundancy, and
representation (Shaffer and Stein 2000,
pp. 306–310). Briefly, resiliency is the
ability of the species to withstand
environmental and demographic
stochasticity (for example, wet or dry,
warm or cold years); redundancy is the
ability of the species to withstand
catastrophic events (for example,
droughts, large pollution events); and
representation is the ability of the
species to adapt to both near-term and
long-term changes in its physical and
biological environment (for example,
climate conditions, pathogens). In
general, species viability will increase
with increases in resiliency,
redundancy, and representation (Smith
et al. 2018, p. 306). Using these
principles, we identified the species’
ecological requirements for survival and
reproduction at the individual,
population, and species levels, and
described the beneficial and risk factors
influencing the species’ viability.
The SSA process can be categorized
into three sequential stages. During the
first stage, we evaluated the individual
species’ life-history needs. The next
stage involved an assessment of the
historical and current condition of the
species’ demographics and habitat
characteristics, including an
explanation of how the species arrived
at its current condition. The final stage
of the SSA involved making predictions
about the species’ responses to positive
and negative environmental and
PO 00000
Frm 00033
Fmt 4700
Sfmt 4700
53513
anthropogenic influences. Throughout
all of these stages, we used the best
available information to characterize
viability as the ability of a species to
sustain populations in the wild over
time. We use this information to inform
our regulatory decision. The following
is a summary of the key results and
conclusions from the SSA report; the
full SSA report can be found at Docket
FWS–R4–ES–2021–0007 on https://
www.regulations.gov.
Summary of Biological Status and
Threats
In this discussion, we review the
biological condition of the species and
its resources, and the threats that
influence the species’ current and future
condition, in order to assess the species’
overall viability and the risks to that
viability.
The Suwannee alligator snapping
turtle is found in the Suwannee River
basin in Georgia and Florida. The
species is mostly aquatic and uses a
variety of habitat types including deeper
water of large rivers and their major
tributaries; however, they are also found
in a wide variety of habitats, including
small streams, springs, bayous, canals,
swamps, lakes, reservoirs, and ponds.
This large turtle species is an
opportunistic feeder and consumes a
variety of foods. Fish comprise a
significant portion of its diet; however,
crayfish, mollusks, smaller turtles,
insects, snakes, birds, and vegetation
(including acorns) have also been
reported (Elsey 2006, pp. 448–489;
Elbers and Moll 2011, entire).
Additional information regarding the
species’ needs is provided in the SSA
report (Service 2022, pp. 4–14) and the
proposed listing rule (86 FR 18014;
April 7, 2021).
Threats
We provide information regarding
past, present, and future influences,
including both positive and negative
influences, on the Suwannee alligator
snapping turtle’s current and future
viability, including illegal harvest
(Factor B), bycatch (Factor E), habitat
loss and degradation (Factor A), nest
predation (Factor C), climate change
(Factor E), and conservation measures.
The existing regulatory mechanisms
(Factor D) have not been adequate to
arrest the decline of the species.
Additional threats such as historical
commercial and recreational harvest
targeting the species, disease, parasitic
insects, boating, and contaminants are
described in the SSA report (Service
2022, pp. 15–22); these additional
threats may negatively affect individuals
of the species or have historically

affected the species, particularly when
compounded with other ongoing
stressors or threats, but they do not
impact the species’ overall current or
future viability.
Harvest (Commercial and Poaching)
Commercial and recreational turtle
harvesting practices in the last century
resulted in a decline of the Suwannee
alligator snapping turtle across its range
(Enge et al. 2014, p. 4). Commercial
harvest of both species of alligator
snapping turtles reached its peak in the
late 1960s and 1970s, when the meat
was used for commercial turtle soup
products and sold in large quantities for
public consumption. In addition, many
restaurants served turtle soup and
purchased large quantities of alligator
snapping turtles from trappers in the
southeastern States (Reed et al. 2002, p.
5). In the 1970s, the demand for turtle
meat was so high that as much as three
to four tons of alligator snapping turtles
(M. temminckii) were harvested from
the Flint River in Georgia per day
(Pritchard 1989, p. 76). The Florida
Game and Fresh Water Fish
Commission (now the Florida Fish and
Wildlife Conservation Commission
(FWC)) reported significant numbers of
turtles being taken from the
Apalachicola and Ochlocknee Rivers to
presumably be sent to restaurants in
New Orleans and other destinations
(Pritchard 1989, pp. 74–75). While such
large-scale removal of Macrochelys
turtles occurred across the range of the
genus, the population demographics of
Suwannee alligator snapping turtles in
Florida indicate there was likely less
commercial harvesting activities in the
Suwannee River drainage than
elsewhere (Enge et al. 2017, p. 6; Enge
et al. 2014, entire; Johnston et al. 2015,
entire).
Florida prohibited the commercial
harvest of all Macrochelys spp. in 1972,
and recreational or personal harvest in
2009; Georgia prohibited all harvest in
1992 (Service 2022, pp. 27–29). Despite
the prohibitions on commercial and
recreational harvest for the species, the
historical removal of large turtles
continues to affect the species due to
their low fecundity, low juvenile
survival, long lifespan, and delayed
maturity. Commercial harvest is not
currently a threat to the Suwannee
alligator snapping turtle, but the effect
of historical, large-scale removal of large
turtles is ongoing.
Although both Florida and Georgia
have prohibited recreational harvest,
there is an international and domestic
demand for turtles for consumption and
for herpetofauna enthusiasts who collect
turtle species for pets (Stanford et al.
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
2020, entire). The Suwannee alligator
snapping turtle is no exception; farmed,
hatchling alligator snapping turtles may
be sold for up to 400 U.S. dollars per
turtle (Lejeune et al. 2020, p. 8;
MorphMarket 2024, unpaginated).
Illegal harvest, or poaching, of
Suwannee alligator snapping turtles
may occur anywhere within the species’
range for both the pet trade and turtle
meat trade. The best available
information regarding potential pressure
from poaching comes from documented
reports by law enforcement agencies
and court cases involving the
congeneric (species within the same
genus) alligator snapping turtle. In 2017,
three men were convicted of violating
the Lacey Act (16 U.S.C. 3371–3378; 18
U.S.C. 42) because they collected 60
large alligator snapping turtles (M.
temminckii) in a single year in Texas
and transported them across State lines
(see United States v. Travis Leger et al.,
No. 1:17–CR–00040 (E.D. Tex.)). We
expect that illegal harvest is affecting
Suwannee alligator snapping turtles,
given it has been documented on many
occasions for the heterospecific alligator
snapping turtle. Illegal harvest is an
ongoing threat to the Suwannee alligator
snapping turtle because removing adult
female turtles from the population
lowers the viability of the species by
reducing reproductive potential; in
addition, the species is long-lived, slow
to mature, and juvenile survival is very
low, making it more difficult for the
historically over-harvested population
to recover.
Aside from the local and domestic use
of turtles, the global demand for pet
turtles and turtle meat continues to
increase. Many species of turtles are
collected from the wild as well as bred
in captivity and are sold domestically
and exported internationally.
Macrochelys spp. are regularly exported
out of the United States, typically as
hatchlings or juveniles, to initiate brood
stock for overseas turtle farms and for
turtle collectors. According to the
Service’s Law Enforcement Management
Information System (LEMIS), which
provides reports about the legal
international wildlife trade, most
shipments of live alligator snapping
turtles exported from 2005 to 2018
consisted of small turtles destined
mostly for Hong Kong and China
(Service 2018, entire). Prior to 2006, up
to 23,780 M. temminckii per year were
exported from the United States (70 FR
74700; December 16, 2005). Since the
time of the proposed listing, the species
has been uplisted to CITES Appendix II
that may provide additional protections
to the species. See the section below for
PO 00000
Frm 00034

additional information, Conservation
Efforts and Regulatory Mechanisms.
Impacts of Harvest
Because of the Suwannee alligator
snapping turtle’s delayed maturity, long
generation times, and relatively low
reproductive output, the species cannot
sustain collection from the wild,
especially of adult females, over any
length of time (Reed et al. 2002, pp. 8–
12). Adult turtles do not reach sexual
maturity until 11 to 21 years of age. A
mature female typically produces only
one clutch per year consisting of 8–52
eggs (Ernst and Barbour 1989, p. 133).
These turtles are characterized by low
survivorship in early life stages, but
surviving individuals may live many
decades once they reach maturity. The
life-history traits of the species (low
fecundity, late age of maturity, and low
survival of nests and juveniles)
contribute to the population’s slow
response rebound after historical overexploitation. Therefore, population
growth rates are extremely sensitive to
the harvest of adult females. Adult
female survivorship of less than 98
percent per year is considered
unsustainable, and a further reduction
of this adult survivorship will generally
result in significant local population
declines (Reed et al. 2002, p. 9),
although dynamics likely vary across
the species’ range. These data
underscore how influential adult female
mortality is on the ability of the species
to maintain viability.
Although regulatory harvest
restrictions have decreased the number
of Suwannee alligator snapping turtles
harvested, populations have not
necessarily increased in response. This
lag in population response is likely due
to the demography of the species—
specifically delayed maturity, long
generation times, and relatively low
reproductive output. The Suwannee
alligator snapping turtle population
remains low despite commercial and
recreational harvest prohibitions
(Florida Fish and Wildlife Conservation
Commission 2017, p. 6). Through expert
elicitation, the magnitude of the threat
of illegal harvest or poaching across the
basin ranges from 20–55 percent of the
species’ range may be affected (Service
2022, p. 28).
Bycatch
Suwannee alligator snapping turtles
can be killed or harmed incidentally
during fishing and other recreational
activities. Some of these threats include
fishhook ingestion; drowning when
hooked on trotlines (a fishing line
strung across a stream with multiple
hooks set at intervals), limb lines, bush

lotter on DSK11XQN23PROD with RULES1

hooks (single hooks hung from
branches), or jug lines (line with a hook
affixed to a floating jug); and injuries or
drowning when entangled in various
types of fishing line. The magnitude of
the threat due to incidental hooking
(i.e., recreational trot and limb lines,
fishing tackle, etc.) as provided though
expert elicitation describes the impact
to the species as affecting between
30–75 percent of the species’ range
(Service 2022, p. 28).
Hoop nets are also used to capture
catfish and baitfish and are made up of
a series of hoops with netting and
funnels where fish enter but are unable
to escape through the narrow entry
point. The nets are left submerged and
may entrap small Suwannee alligator
snapping turtles that enter the traps and
are unable to escape. Actively used or
discarded fishing line and hooks pose
harm to Suwannee alligator snapping
turtles. They can ingest baited fishhooks
and attached fishing line and depending
on where ingested hooks and line lodge
in the digestive tract, they can cause
harm or death (Enge et al. 2014, pp. 40–
41). For example, hooks and line can
cause gastrointestinal tract blockages,
and the hooks can puncture the
digestive organs, leading to mortality
(Enge et al. 2014, pp. 40–41). Fishhooks
have been found in the gastrointestinal
tracts of radiographed Suwannee
alligator snapping turtles (Enge et al.
2014, entire; Thomas 2014, pp. 42–43).
Trotlines also negatively affect
Suwannee alligator snapping turtles.
Trotlines are a series of submerged lines
with hooks off a longer line. Trotline
fishing involves leaving the lines
unattended for extended periods, before
returning to check them. Limblines and
bush hooks are similar to trot lines in
that they are typically set and left
unattended; however, they only use a
single hook. The turtles can become
entangled in the lines and drown, as
well as ingest trotline hooks and lines,
also causing drowning or internal
injuries. Bycatch from trotlines that
resulted in mortality of Macrochelys
turtles has been well documented. Dead
turtles have been found on lines that
had seemingly been abandoned (Moore
et al. 2013, p. 145). The lines and hooks
may also become dislodged from their
place of attachment when left
unattended, becoming aquatic debris
that remains in the waterway for
extended periods of time and may
continue to be an entanglement hazard
for many species, including Suwannee
alligator snapping turtles.
Habitat Alteration and Degradation
The Suwannee alligator snapping
turtle’s aquatic and nesting habitats

Jkt 262001
have been altered by anthropogenic
disturbances. Changes in the riparian or
nearshore areas affect the amount of
suitable soils for nesting sites because
the species constructs nests on land
near the water. Riparian cover is
important as it moderates in-stream
water temperatures and dissolved
oxygen levels. In addition to affecting
the distribution and abundance of
alligator snapping turtle prey species,
these microhabitat conditions affect the
snapping turtles directly. Moderate
temperatures and sufficient dissolved
oxygen levels allow the turtles to remain
stationary on the stream bottom for
longer periods, increasing the ambush
foraging opportunities. Changes in the
riparian structure may affect the
microclimate and conditions of the
associated water body, directly affecting
the foraging success of the turtles.
Activities and processes that can alter
habitat include dredging, deadhead
logging (removal of submerged or
partially submerged snags, woody
debris, and other large vegetation for
wood salvage), removal of riparian
cover, channelization, stream bank
erosion, siltation, and land use adjacent
to rivers (e.g., clearing land for
agriculture). These activities negatively
influence habitat suitability for
Suwannee alligator snapping turtles.
Erosion can change the stream bank
structure, affecting the substrate that
may be suitable for nesting or accessing
nesting sites. Siltation affects water
quality and may reduce the health and
availability of prey species.
Channelization destroys the natural
benthic habitat and also affects the
water depth and normal flow.
Submerged obstacles may be removed
during the channelization, which affects
the microhabitat dynamics within the
waterway and removes important
structures for alligator snapping turtles
to use for resting, foraging, and cover
from predators. While channelization
within the species’ range does not
regularly occur, it is not prohibited.
Deadhead logs and fallen riparian
woody debris, where present, provide
refugia during low-water periods and
resting areas for all life stages and
support important feeding areas for
hatchlings and juveniles (Enge et al.
2014, p. 40; Ewert et al. 2006, p. 62).
Suwannee alligator snapping turtle
habitat is also influenced by water
availability and quantity, as well as
water quality, across the species’ range.
Ground water withdrawals in the
Florida portion of the species’ range are
managed by the Suwannee River Water
Management District (SRWMD);
withdrawals increased by 64 percent
between 1975 and 2000, mostly for
PO 00000
Frm 00035
Fmt 4700
Sfmt 4700
53515
irrigation. Most withdrawals in the
basin occur in agricultural areas along
the Suwannee River during the spring
(March through May) (Thom et al. 2015,
p. 2). Water withdrawals may reduce
flow in some streams, effectively
isolating some turtles from the rest of
the population or making immature
turtles more vulnerable to predators.
Additionally, reduced water levels may
impact prey abundance and distribution
through restricting habitat connectivity,
reducing dissolved oxygen levels, and
increasing water temperatures.
Water quality may also be a factor for
Suwannee alligator snapping turtles as
contaminants enter the aquatic systems
through runoff. The Lower Suwannee
River’s middle and lower basins are
directly impacted by nutrients,
including nitrates. Agricultural
practices are the main source of nitrates,
which specifically come from fertilizers
and in some cases from manure and
other waste products. They introduce
nitrates to the river and groundwater
(i.e., springs) through surface runoff and
groundwater seepage. Groundwater
seepage transports nitrates to the
aquifer, which then reemerge through
springs and other groundwater
discharge, especially during low-flow
periods (Pittman et al. 1997, entire; Katz
et al. 1999, entire; Thom et al. 2015, p.
2).
The direct effects of water quality and
water quantity on the Suwannee
alligator snapping turtle have not been
quantified; however, as the human
population that relies on water systems
in the species’ range continues to
increase, the indirect effects across the
entire range, coupled with other
stressors, is likely to further reduce the
species’ viability. Underscoring the
potential severity of this threat,
Florida’s human population is
anticipated to grow from nearly 21.5
million in 2019 to more than 24.0
million by 2030 (Rayer and Wang 2020,
p. 9). The public water supply demand
will increase with increased human
population growth. All counties within
the species’ range in Florida (Alachua,
Bradford, Columbia, Dixie, Gilchrist,
Hamilton, Lafayette, Levy, Madison,
Suwannee, and Union Counties) are part
of the SRWMD supply area and are
projected to increase the public water
supply demand by an average of 11.29
percent in millions of gallons of water
per day from 2010 to 2035 (SRWMD
2015, p. 42). In addition, the human
population in these counties will
experience an average of 17.25 percent
population growth from the year 2010 to
2035 (SRWMD 2015, p. 43). As the
human population increases, other
threats to the species and its habitat are

likely to increase. For example,
recreational use of the Suwannee River
will more than likely continue to rise,
which will increase human encounters
with Suwannee alligator snapping
turtles through incidental bycatch. Also,
more development may result in an
increase in contaminated runoff and
declines in water quality.

Nest Predation
Nest predation rates for Macrochelys
spp. are high. Raccoons (Procyon lotor)
are common nest predators, but ninebanded armadillos (Dasypus
novemcinctus), Virginia opossums
(Didelphis virginiana), bobcats (Lynx
rufus), and river otters (Lontra
canadensis) may also depredate nests
(Ernst and Lovich 2009, p. 149; Ewert et
al. 2006, p. 67; Holcomb and Carr 2013,
p. 482). Additional nonnative species
found within the species’ range that
may depredate nests include feral pigs
(Sus scrofa) and invasive red imported
fire ants (Solenopsis invicta) (Pritchard
1989, p. 69). Although not documented
in Suwannee alligator snapping turtle
nests, fire ants are prevalent across the
species’ range, and predation by fire
ants was the suspected culprit in the
failure of alligator snapping turtle (M.
temminckii) nests in Louisiana
(Holcomb 2010, p. 51). Beyond nest
failure, some hatchlings endured
wounds inflicted by fire ants that led to
the loss of a limb or tail, which reduced
their mobility and their chance of
survival (Holcomb 2010, p. 72). The
recovery of the species from historical
overharvest depends on successful
reproduction and survival of young. The
currently low population size does not
allow for absorbing the impact of
elevated nest predation. The degree of
added threat from the newer, introduced
nest predators is unknown, but we can
conclude that the overall threat from
nest predation is greater than it was in
the past because of introduced predators
such as feral hogs, and fire ants. The
magnitude of nest predation by native
and exotic species affected between 5–
10 percent of the spatial extent of the
species’ range, as provided through
expert elicitation (Service 2022, p. 28).
Coupled with other threats, nest
predation will continue to negatively
affect the species’ overall viability.
Climate Change
Climate change may also affect the
Suwannee alligator snapping turtle to
varying degrees, but the extent of impact
is influenced by certain geographical
factors, including proximity to the coast
and latitudinal thermogradients.
Climate change may affect the
Suwannee alligator snapping turtle in
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
several ways. First, the effects of
decreased precipitation due to climate
change will cause an increase in water
withdrawal for human use (i.e., potable
water and agriculture irrigation).
Additionally, reduced precipitation may
directly and indirectly impact habitat,
food, and water availability throughout
the Suwannee River basin. Available
water will be reduced as evaporation
increases with continued warming
temperatures. Furthermore, increased
temperatures may have physiological
impacts on sex ratios because these
turtles have temperature-dependent sex
determination, and higher temperatures
may skew the sex ratio.
In the southeastern United States,
temperatures are predicted to warm by
4 to 8 degrees Fahrenheit (°F) (2.2 to 4.4
degrees Celsius (°C)) by 2100 (Carter et
al. 2014, p. 399). Temperature
determines the sex of the Macrochelys
developing embryos; certain nest
temperatures result in primarily male
hatchlings with females produced at
temperatures of the two extremes of the
intermediate male-producing
temperatures. Females are produced
when the nest temperatures are either
cooler or warmer than the temperature
threshold for male development. In
order to develop mixed ratios of both
sexes, fluctuating temperatures near the
intermediate and extremes are ideal. In
addition to temperature effects on sex
ratio, temperature has been associated
with nest viability, with highest
viability in nests with intermediate sex
ratios (produced at the male-producing
intermediate temperature range with
fluctuations of warmer or cooler
temperatures for female-producing
temperatures during the incubation
period) and lowest in nests with femalebiased sex ratios (Ewert and Jackson
1994, pp. 28–29). Thus, warming
temperatures might lead to Suwannee
alligator snapping turtle nests with
strongly female-biased sex ratios. These
skewed sex ratios may result in
declining viability as mating behaviors
are altered and other issues with
unbalanced populations arise.
Collectively, these impacts from
reduced precipitation and increased
temperature would reduce the quality or
availability of suitable habitat for the
Suwannee alligator snapping turtle
(Thom et al. 2015, p. 126). Climate
change impacts on the Suwannee
alligator snapping turtle will likely act
in concert with, and exacerbate, the
impacts of other threats and stressors.
Other Stressors
Other stressors that may affect
Suwannee alligator snapping turtles
include disease, nest parasites,
PO 00000
Frm 00036
Fmt 4700
Sfmt 4700
contaminants from urban and
agricultural runoff, and historical
recreational harvest, but none of these
stressors are having species-level
impacts on the Suwannee alligator
snapping turtle. These stressors may act
on individuals or have highly localized
impacts. While each is relatively
uncommon, these stressors may
exacerbate the effects of other ongoing
threats.
Additional information on these
stressors acting on the species is
available in the species’ SSA report
under ‘‘Factors Influencing Viability’’
(Service 2022, pp. 23–29). This
information includes historical and
current threats that have caused and are
causing a decline in the species’
viability. The primary threats currently
acting on the species include illegal
harvest, nest predation, and hook
ingestion and entanglement due to
bycatch associated with freshwater
fishing. These primary threats are not
only affecting the species now but are
expected to continue impacting the
species and were included in the
species’ future condition projections in
the SSA report (Service 2022, pp. 41–
56).
Conservation Efforts and Regulatory
Mechanisms
Clean Water Act
Section 401 of the Federal Clean
Water Act (CWA; 33 U.S.C. 1251 et seq.)
requires that an applicant for a Federal
license or permit provide a certification
that any discharges from the facility will
not degrade water quality or violate
water-quality standards, including
State-established water quality standard
requirements. Section 404 of the CWA
establishes programs to regulate the
discharge of dredged and fill material
into waters of the United States.
Nationwide, regional general, or
individual permits are issued by the
Florida Department of Environmental
Protection or U.S. Army Corps of
Engineers to fill wetlands; to install,
replace, or remove culverts; to install,
repair, replace, or remove bridges; or to
realign streams or water features. These
permit types are summarized below.
• Nationwide permits are for ‘‘minor’’
impacts to streams and wetlands, and
do not require an intense review
process. The impacts allowed under
nationwide permits usually include
projects affecting stream reaches less
than 150 ft (45.72 m) in length, and
wetland fill projects up to 0.50 acres
(0.2 hectares). Mitigation is usually
provided for the same type of wetland
or stream impacted and is usually at a
2:1 ratio to offset losses.

Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
lotter on DSK11XQN23PROD with RULES1
• Regional general permits are for
various specific types of impacts that
are common to a particular region; these
permits will vary based on location in
a certain region or State.
• Individual permits are for the
larger, higher impact, and more complex
projects. These require a complex
permit process with multi-agency input
and involvement. Impacts in these types
of permits are reviewed individually,
and the compensatory mitigation chosen
may vary depending on the project and
types of impacts.
The CWA regulations, set forth in title
40 of the Code of Federal Regulations
(CFR) for the Environmental Protection
Agency and in title 33 of the CFR for the
U.S. Army Corps of Engineers, ensure
proper mitigation measures are applied
to minimize the impact of activities
occurring in streams and wetlands
where the species occurs. These
regulations contribute to the
conservation of the species by
minimizing or mitigating the effects of
certain activities on Suwannee alligator
snapping turtles and their habitat.
Convention on International Trade in
Endangered Species of Wild Fauna and
Flora (CITES)
Suwannee alligator snapping turtle is
included in the CITES Appendices
under Macrochelys temminckii, based
on the CITES standard nomenclature
reference for turtles (Fritz & Havaš 2007,
p. 172), which recognizes M. temminckii
as the only taxon in the genus
Macrochelys. This species was
originally included in CITES Appendix
III in 2006, when the genus was
recognized as a single species, described
as Macroclemys and synonymous with
Macrochelys (70 FR 74700; December
16, 2005). At the 19th Conference of the
Parties (November 2022), Macrochelys
temminckii was transferred from
Appendix III of CITES to Appendix II
(CITES 2023, pp. 45–46). Because CITES
only recognizes a single species of
Macrochelys (M. temminckii), both taxa,
the alligator snapping turtle and the
Suwannee alligator snapping turtle, are
protected under CITES Appendix II
regulations.
CITES requires permits for exports of
Appendix II species, which are only
issued when: (1) the Scientific
Authority has advised that the export
will not be detrimental to the survival
of the species; (2) the Management
Authority is satisfied that the
specimen(s) were legally acquired; and
(3) the Management Authority is
satisfied that any living specimens will
be prepared and shipped so as to
minimize the risk of injury, damage to
health, or cruel treatment. Export

numbers are also monitored by U.S.
CITES Authorities and reported to
CITES annually. Whenever a Scientific
Authority determines that the export of
specimens of any such species should
be limited in order to maintain that
species throughout its range at a level
consistent with its role in the
ecosystems in which it occurs and well
above the level at which that species
might become eligible for inclusion in
Appendix I, the Scientific Authority
shall advise the appropriate
Management Authority of suitable
measures to be taken to limit the grant
of export permits for specimens of that
species.These requirements help
regulate and document legal,
international trade; they further ensure
that specimens entering international
trade are acquired legally, and that the
trade of the species is biologically
sustainable for, and will not be
detrimental to the survival of, the
species. Thus, Appendix II regulations
complement and lend additional
support to State wildlife agencies in
their efforts to regulate and manage
these species, improve data gathering to
increase knowledge of trade in the
species, and strengthen State and
Federal wildlife enforcement activities
to prevent poaching and illegal trade.
When this taxon was included in
CITES Appendix III, reporting of annual
exports was also required. While CITES
reporting indicates the number of turtles
exported with other relevant data, in the
past, the information required for the
export reports has not always accurately
identified the source stock of the
exported turtle(s). Most alligator
snapping turtles that were exported
between 2005 and 2018 were identified
as ‘‘wild’’ individuals; however, many
were likely from farmed parental stock
(Service 2018, entire). The discrepancy
in reporting the actual source of the
internationally exported turtles has not
allowed us to easily evaluate the impact
of export on Suwannee alligator
snapping turtles. Inclusion in Appendix
II, unlike Appendix III, requires an
evaluation that the export will not be
detrimental to the survival of the
species, which will help better assess
the impact of export.
National Wildlife Refuges
Approximately 5 percent of the
Suwannee alligator snapping turtle’s
range includes areas within two
National Wildlife Refuges (NWR),
Okefenokee in Georgia and Lower
Suwannee in Florida. These NWRs are
managed by the Service to conserve
native wildlife species and their habitats
and are protected from future
development. Both NWRs have
PO 00000
Frm 00037
Fmt 4700
Sfmt 4700
53517
comprehensive conservation plans
(CCP) that ensure each NWR is managed
to fulfill the purpose(s) for which it was
established.
Okefenokee NWR is at the
northernmost proximity of the species’
range and is a freshwater wetland. There
are only a few anecdotal reports of the
species occurring within Okefenokee
NWR. There have been no systematic
surveys conducted within the swamp,
so the extent of use by the species of
that area has not yet been documented.
However, the paucity of documented
and anecdotal records from the
surrounding areas would indicate that
the species is not common or
widespread at this location.
The Okefenokee NWR CCP includes a
strategy within the wildlife management
goal to ‘‘develop and implement surveys
to determine distribution and
population status of amphibians and
reptiles, particularly those species that
are threatened, endangered, or species
of special concern.’’ The CCP also
includes an objective to ‘‘identify factors
influencing declines in the refuge’s
fishery by examining water chemistry,
groundwater withdrawals, water
quality, pH levels, invertebrate
populations, and the physical
environment’’ (Service 2006, pp. 84–86).
This knowledge would clearly benefit
management of the Suwannee alligator
snapping turtle.
The Lower Suwannee NWR is at the
mouth of the Suwannee River where it
feeds into the Gulf of Mexico. Twenty
miles of the Suwannee River is within
the refuge and is suitable habitat for
Suwannee alligator snapping turtles,
albeit less so as salinity increases the
closer the river gets to the Gulf of
Mexico. The species is considered
common within the refuge, and nesting
has been confirmed; however, the
species is not commonly seen (due to
their ability to burrow into the river or
creek banks, or to sit on the bottom of
the river and stay submerged until
surfacing for air is needed), and cryptic
coloration when submerged makes
detection of the species very difficult
(Woodward 2021, pers. comm.). The
Lower Suwannee NWR CCP includes
management actions that may benefit
the species and provides goals for
wildlife, habitat, and landscape
management. The CCP’s objectives and
strategies provide that the refuge
monitor and manage wildlife
populations, manage the habitats for
endangered and threatened species and
species of special concern in the State
of Florida, and promote interagency and
private landowner cooperation (Service
2001, pp. 11–22). The Lower Suwannee
River NWR provides logistical,

Department of Defense—Moody Air
Force Base
Moody Air Force Base (Base) is near
Valdosta, Georgia, and has many
freshwater ponds and a large lake,
Mission Lake, that drains into the Grand
Bay system. Suwannee alligator
snapping turtles do not commonly occur
on the Base, but they are occasionally
found. The Base’s integrated natural
resources management plan (INRMP)
describes Macrochelys as occurring on
the Base; however, there are no
management activities described
directly for the species in the INRMP.
The Department of Defense ensures
INRMPs are consistent with the Sikes
Act Improvement Act of 1997, as
amended through 2010 (16 U.S.C. 670 et
seq.), which requires the preparation,
implementation, update, and review of
an INRMP for each military installation
in the United States and its territories
with significant natural resources.
State Protections
The Suwannee alligator snapping
turtle is protected by State law in both
Florida and Georgia as a threatened
species. Florida Administrative Code
rule 68A–27.003 makes it illegal to take,
possess, or sell (except as specifically
permitted or authorized) species listed
as federally designated endangered or
threatened species and State-designated
threatened species; this includes the
species’ parts, their nests, and their
eggs. Since the original 2011 biological
status review for the Suwannee alligator
snapping turtle (FWC 2011, entire), two
species of alligator snapping turtle were
differentiated based upon genetic and
skeletal differences (Thomas 2014,
entire), necessitating new biological
status reviews of both species. During
FWC’s 2017 biological assessment of
Macrochelys, the biological review
group determined that M. suwanniensis
was distinct and warranted designation
as State-threatened based upon
International Union for Conservation of
Nature (IUCN) Red List criteria (Enge et
al. 2017. p. 3).
Florida developed a species action
plan (SAP) that includes all
Macrochelys spp. due to their similarity
in appearance, vulnerability to
deliberate human take, incidental take
with fishing gear, pollution, riverine
habitat alteration, and nest predation
(FWC 2018, p. iii). The objectives of the
SAP include habitat conservation and
management, population management,
monitoring and research, rule and
VerDate Sep<11>2014

permitting intent, law enforcement,
incentives and influencing, education
and outreach, and coordination with
other entities (FWC 2018, pp. 10–27).
Implementation of the Macrochelys spp.
SAP is ongoing (FWC 2018, entire).
FWC has established a team of biologists
who continue to study the species to
better understand the species and
population trends.
Both Macrochelys suwanniensis and
M. temminckii are found in Georgia, but
their ranges do not overlap. Georgia
listed M. temminckii as threatened in
1992, which at the time included both
species, and continues to cover both
species as threatened. State law protects
threatened animal species by
prohibiting their harassment, capture,
killing, sale, and purchase, as well as
the destruction of their habitat on public
lands (Georgia Administrative Code,
rule 391–4–10–.06). In the State’s
wildlife action plan, the Department of
Natural Resources indicates they intend
to conduct genetic, taxonomic, and
reproductive studies of high-priority
species (GDNR 2015, p. D–5). Current
State regulations are intended to
minimize the impact of poaching and
also contribute to the conservation of
the species through public outreach.
State and Federal Stream Protections
(Deadhead Logging)
Structural features within the water
are important components of the habitat
for Suwannee alligator snapping turtles.
Submerged and partially submerged
vegetation provide feeding and
sheltering areas for all age classes. The
structural diversity and channel
stabilization created by instream woody
debris provides essential habitat for
spawning and rearing aquatic species
(Bilby 1984, p. 609; Bisson et al. 1987,
p. 143). Snag or woody habitat was
reported as the major stable substrate in
southeastern Coastal Plain sandy-bottom
streams and a site of high invertebrate
diversity and productivity (Wallace and
Benke 1984, p. 1651). Wood enhances
the ability of a river or stream ecosystem
to use the nutrient and energy inputs
and has a major influence on the
hydrodynamic behavior of the river
(Wallace and Benke 1984, p. 1643). One
component of this woody habitat is
deadhead logs, which are sunken
timbers from historical logging
operations. Deadhead logging is the
removal of submerged cut timber from
a river or creek bed and banks.
However, current State regulations
minimize the impact of deadhead
logging on the Suwannee alligator
snapping turtle. Florida allows
deadhead logging only with proper
permits from the Florida Department of
PO 00000
Frm 00038

Environmental Protection; this State
agency assesses the proposed activity’s
impacts on wildlife before issuing a
permit. Further, the State of Florida
prohibits deadhead logging in some of

Georgia is not currently processing
permits; therefore, deadhead logging is
not currently being permitted in any of
Georgia’s waterways.
State and Federal Stream Protections
(Buffers and Permits)
A buffer such as a strip of trees,
plants, or grass along a stream or
wetland naturally filters out dirt and
pollution from rainwater runoff before it
enters rivers, streams, wetlands, and
marshes. This vegetation not only serves
as a filter for the aquatic system, but the
riparian cover influences microhabitat
conditions such as in-stream water
temperature and dissolved oxygen
levels. These habitat conditions not only
influence the distribution and
abundance of alligator snapping turtle
prey species but also directly affect
Suwannee alligator snapping turtles.
Moderate temperatures and sufficient
dissolved oxygen levels allow the turtles
to remain stationary on the stream
bottom for longer periods, increasing
their ambush foraging opportunities.
Loss of riparian vegetation and canopy
cover result in increased solar radiation,
elevation of stream temperatures, loss of
allochthonous (organic material
originating from outside the channel)
food material, and removal of
submerged root systems that provide
habitat for alligator snapping turtle prey
species (Allan 2004, pp. 266–267).
The Georgia Erosion and Sediment
Control Act of 1975 restricts disturbance
and trimming of vegetation within a 25ft (7.62-m) buffer adjacent to creeks,
streams, rivers, saltwater marshes, and
most lakes and ponds, and the Georgia
Planning Act of 1989 requires some
local governments to adopt a 100-ft
(30.48-m) buffer. Georgia also has a nonpoint water pollution source
management program under which the
State established and updates a
nonpoint source management plan; this
plan sets long-term goals and short-term
activities for the State, partners, and
stakeholders to address non-point
source pollution. Although not focused
on buffers per se, the Florida Surface
Water Improvement and Management
Act of 1987 addresses Statewide nonpoint source pollution impacts to
waterbodies on a landscape scale and
partners with Federal, State, and local
governments, and the private sector to
restore damaged ecosystems and
prevent pollution from storm water
runoff. These State laws provide

Suwannee River Water Management
District (SRWMD)
Water conservation measures
restricting lawn and landscaping
irrigation can benefit the Suwannee
alligator snapping turtle by limiting
water withdrawal, which directly
benefits the turtle through maintaining
available habitat and supporting habitat
for prey species, and by reducing runoff
of fertilizers and other turf management
chemicals that could disrupt or alter
water chemistry in the streams. The
SRWMD manages the water and other
related resources within the range of the
Suwannee alligator snapping turtle
including the Suwannee,
Withlacoochee, Alapaha, Santa Fe, and
Ichetucknee Rivers within Florida. The
agency monitors the water quantity and
quality by regular testing and reporting.
It also implements water-use restrictions
to conserve freshwater resources of
springs and rivers within the SRWMD.
Unnecessary water use is discouraged,
and landscape irrigation restrictions are
implemented as needed, such as
limiting watering to twice per week
based on district water conservation
measures that apply to residential
landscaping, public or commercial
recreation areas, and businesses that are
not regulated by a district-issued water
use permit (SRWMD 2021,
unpaginated). Landscape irrigation
accounts for the largest percentage of
household water use in the State of
Florida. Mandatory lawn and landscape
watering measures are in effect
throughout the SRWMD. These
restrictions contribute to maintaining
healthy groundwater level and flows.
Current Condition
The current condition for the
Suwannee alligator snapping turtle
considers the current abundance,
current threats, and current
conservation actions in the context of
what is known about the species’
historical range. In order to determine
species-specific population and habitat
factors along with threats and
conservation actions influencing the
species, expert elicitation was used in
the absence of available related
information. To describe Suwannee
alligator snapping turtle’s current
resiliency, redundancy, and
representation, we assessed the species
as a single population, because there is
evidence that the turtles may move
between the mouths of the Suwannee
and Santa Fe Rivers in Florida. The
VerDate Sep<11>2014

Jkt 262001
entire species is estimated to have an
abundance of 2,000 turtles across its
entire range in Georgia and Florida
(Service 2022, p. 34).
The primary threats currently acting
on the species include illegal harvest,
nest predation, and hook ingestion and
entanglement due to bycatch associated
with freshwater fishing. Other stressors
acting on the species include historical
commercial and recreational harvest,
habitat alteration and degradation, and
the effects of climate change. The
species is State-listed as threatened in
both Florida and Georgia. When
evaluating range expansion or
constriction, recent surveys have
confirmed minimal change in the
known, limited historical range.
The resiliency of the single Suwannee
alligator snapping turtle population is
described according to its abundance,
threats, and range expansion or
contraction. Current resilience was
assessed as current abundance, along
with information about current threats,
conservation actions, and distribution
serving as auxiliary information about
the causes and effects of current versus
historical abundances. There is little
information with which to make
rigorous comparisons between current
and historical abundances; however,
population depletions historically
occurred for consumption and
cumulated through the 1970s, when
turtles and turtle meat were exported
regionally for commercial use.
Information about the magnitude of the
changes in abundance over time comes
from anecdotal observations by trappers
(Pritchard 1989, pp. 74, 76, 80, 83). The
historical large-scale removal of large,
reproductive turtles from the population
for commercial harvest continues to
affect the species and its ability to
rebound. The species is described as a
single population with an estimated
abundance of 2,000 turtles across most
of its historical range. As a result of the
impacts from historical and ongoing
threats, as described above, the
population size has been reduced from
historical levels. This decline has
impacted the current ability of the
species to withstand environmental
stochasticity. Additional information
regarding current condition descriptions
is included in the SSA report (Service
2022, pp. 30–40).
The home range for Suwannee
alligator snapping turtles has been
reported between 780 ft (243 m) and
6,604 ft (2,013 m) (Thomas 2014, pp.
41–42). Turtles are not confined to any
part of their range as long as there are
no physical barriers; while this species
is aquatic with the exception of nesting,
these turtles are capable of moving

Frm 00039
Fmt 4700

across land if necessary, as conditions
become unsuitable or resources are
diminished. When describing the
species’ representation, for the purposes
of the SSA in evaluating the species’
current and future viability, the species
consists of a single representative unit.
Representation is used to describe the
species’ ability to withstand
environmental changes over time, or the
species’ adaptive capacity. We describe
the species in terms of its adaptive
capacity with its ability to acclimate to
environmental stressors (Service 2022,
pp. 37–39). We considered life-history
attributes and assessed the species’
propensity to respond to chronic
environmental influences (Thurman et
al. 2020, entire). The species has a type
3 survivorship curve, meaning only a
few individuals reach maturity with
adults usually having a long life span.
This type of survivorship limits the
Suwannee alligator snapping turtle to an
overall low to moderate adaptive
capacity in the life-history and
demographic attributes. The high rating
of its fecundity and parity is
overshadowed by the low rate of
hatchling survivorship to maturity. The
low level of parental investment allows
females to nest and resume feeding and
sheltering activities with minimal
impacts to their health, thus allowing
for a high adaptive capacity for this
attribute. The species has a moderate to
high adaptive capacity in the
distribution, movement, evolutionary
potential, ecological role, and abiotic
niche attributes. The life history and
demographic attributes used in
determining the species’ adaptive
capacity have the greatest influence on
the species’ ability to respond to
changes in its physical and biological
environments over time. Therefore,
representation will continue to be low
to moderate.
The best available science regarding
the species indicates there is no genetic
variation within the species’ single
population across the species’ range that
would allow for delineating additional
representative units.
The Suwannee alligator snapping
turtle’s redundancy is likewise limited
to the single population, with an
estimated abundance of 2,000 turtles,
across its range. Redundancy is related
to a species’ response to a catastrophic
event. While there is only a single
population, it is widely distributed
across the historical range; therefore, the
chance of a catastrophic event affecting
the entire species is very low.
In summary, the overall current
condition of the species’ viability is
affected by the residual effects of
historical overharvest, historical and
E:\FR\FM\27JNR1.SGM
27JNR1
53520
Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
ongoing impacts from recreational
fishing, including incidental limb line/
bush hook take and bycatch, and from
hook ingestion, illegal harvest, habitat
alteration, nest predation, and the
species’ life history (i.e., low annual
recruitment and delayed sexual
maturity). Because of these threats, and
particularly the legacy effects of
historical harvest, the overall current
condition is a single population with an
estimated abundance of 2,000 turtles
across most of the species’ historical
range. The species’ resiliency is likely
lower than it was historically as a result
of the loss of reproductive females and
the species’ life history (long-lived, late
age to sexual maturity, low intrinsic
growth rate). However, the species was
not well-studied historically, so there is
little information (anecdotal
observations) with which to make
comparisons between historical and
current abundance estimates.
Redundancy and representation are
limited, respectively, since the species
is considered a single population with
little genetic variability and there are no
physical barriers to movement.
Future Condition
The future condition of the Suwannee
alligator snapping turtle is described in
detail in the SSA report (Service 2022,
pp. 41–56). When evaluating the
species’ future viability, we consider the
current condition of the species and the
threats acting on the species to develop
a model to determine future trends of
species’ estimated abundance. We
applied six plausible scenarios that
factored in the estimated abundance and
threats acting on the species to project
the future resiliency of the Suwannee
alligator snapping turtle (see table,
below). Three scenarios consider
conservation actions to be applied,
while the remaining three scenarios
project conditions with no conservation
actions. Conservation actions that could
decrease the spatial extent of habitat
threats include but are not limited to:
increased enforcement of state laws or
law enforcement presence to reduce
poaching or bycatch on illegally set trot
or limb lines, prohibited recreational
fishing or certain gear (e.g., trotlines,
hoopnets) in the Suwanee River basin,
and management actions that reduce the
densities of nest predators. In addition
to habitat modification, long term
female population augmentation can be
implemented by head-starting and
captive breeding programs by Federal,
State, and non-governmental
organizations. The actual amount that
any of these actions would influence the
prevalence of threats will depend on
factors like the time, money, personnel,
and conservation partners available, but
we selected a 25 percent reduction in
the spatial extent of threats to explore
how much a change of that amount
affected future population dynamics
(Service 2022, pp. 37–38).
To assess future conditions and the
viability of the Suwannee alligator
snapping turtle, we constructed a
female-only, stage-structured matrix
population model to project the
population dynamics over 50 years to
encompass a two-generation period for
the species and the reliability in
predicting the response to the threats in
that time frame. Species experts
identified five primary threats that were
likely to reduce stage-specific survival
probabilities: commercial fishing
bycatch (includes entanglement,
drowning, or otherwise dying from
interaction with fishing gear;
influencing hatchling, juvenile, and
adult survival), recreational fishing
bycatch (has the same impacts as
commercial fishing bycatch; influenced
juvenile and adult survival), hook
ingestion (surviving a bycatch event but
enduring the lingering effects of an
ingested hook; influenced juvenile and
adult survival), illegal collection (i.e.,
poaching; influenced hatchling,
juvenile, and adult survival), and
subsidized nest predators (influenced
nest survival) with two having the
greatest impact (illegal harvest and nest
predation). The subsidized nest predator
threat reflects additional nest
depredation beyond what would be
expected from common nest
mesopredators (e.g., raccoons and
opossums), with fire ants (Solenopsis
spp.) being the primary nest predator.
We used the best available
information from the literature to
provide values for the population matrix
and elicited data from species experts to
quantify stage-specific initial
abundance, the spatial extent of threats,
and threat-specific percent reductions to
survival. To account for potential
uncertainty in the effects of each threat,
the six future scenarios were divided
along a spectrum: threat-induced
reductions to survival were decreased
by 25 percent, were unaltered, or were
increased by 25 percent. To simulate
conservation actions, the spatial extent
of each threat was either left the same
or reduced by 25 percent (see table,
below). The 25 percent was selected
using expert input and included a
logical extent in which we would expect
to see evident impacts to the
population. We used a fully stochastic
projection model that accounts for
uncertainty in demographic parameters
to predict future conditions of the
Suwannee alligator snapping turtle
units under the six different scenarios.
We then used the model output to
predict the probability of extinction and
quasi-extinction. In the model, quasiextinction is defined as the point in
time at which the Suwannee alligator
snapping turtle population declined to
less than 5 percent of the starting
abundance (females only). Time to
quasi-extinction varied across scenarios,
but in general, the Suwannee River
basin is likely to reach this in 32–42
years (Service 2022, p. 46).

Suwannee alligator snapping turtle
abundance was predicted to decline
over the next 50 years in all six
scenarios. The single population’s
resiliency measure also declined as
abundance declined. Given the high
uncertainties parameterized in the
model, the species does not have a high
likelihood of extinction in the basin
within 50 years, however the loss of 95
percent of the adult female abundance
is expected to occur (quasi-extinction)
Resiliency continues to decline in all
scenarios.
Future representation for Suwannee
alligator snapping turtle is expected to
decline as the adaptive capacity for the
distribution, movement, evolutionary
potential, ecological role, and abiotic
ecological attributes may not provide
the species with the capacity to offset
the low to moderate life history and
demography complexes. These two
attribute categories directly impact
reproduction and the ability to maintain
or to grow the population.
Representation is further reduced by the
continued impacts of human activities
(e.g., unattended fishing gear and
reduced water flow) and the probability
of low numbers of adult females within
the population. (Service 2022, p. 48).
Future redundancy for Suwannee
alligator snapping turtle is expected to
decline over the next 50 years. Where
the species persists in the future, they
are predicted to be rare and not found
in resilient groupings. The addition of
conservation actions, or different
assumptions about the impact of threats
on the species’ demography may alter
the time to quasi- extinction by about a
decade at most, typically less. No
scenarios resulted in stable or increasing
population within the Suwannee River
basin (Service 2022, p. 48).
We note that, by using the SSA
framework to guide our analysis of the
scientific information documented in
the SSA report, we have analyzed the
cumulative effects of identified threats
and conservation actions on the species.
To assess the current and future
condition of the species, we evaluate the
effects of all the relevant factors that
may be influencing the species,
including threats and conservation
efforts. Because the SSA framework
considers not just the presence of the
factors, but to what degree they
collectively influence risk to the entire
species, our assessment integrates the
cumulative effects of the factors and
replaces a standalone cumulative effects
analysis.

Determination of Suwannee Alligator
Snapping Turtle Status
Section 4 of the Act (16 U.S.C. 1533)
and its implementing regulations (50
CFR part 424) set forth the procedures
for determining whether a species meets
the definition of an endangered species
or a threatened species. The Act defines
an ‘‘endangered species’’ as a species in
danger of extinction throughout all or a
significant portion of its range, and a
‘‘threatened species’’ as a species likely
to become an endangered species within
the foreseeable future throughout all or
a significant portion of its range. The
Act requires that we determine whether
a species meets the definition of
endangered species or threatened
species because of any of the following
factors: (A) The present or threatened
destruction, modification, or
curtailment of its habitat or range; (B)
overutilization for commercial,
recreational, scientific, or educational
purposes; (C) disease or predation; (D)
the inadequacy of existing regulatory
mechanisms; or (E) other natural or
manmade factors affecting its continued
existence.
Status Throughout All of Its Range
After evaluating threats to the
Suwannee alligator snapping turtle and
assessing the cumulative effect of the
threats under the Act’s section 4(a)(1)
factors, we determined that the
historical and ongoing threats that are
acting on the Suwannee alligator
snapping turtle include illegal harvest
and collection (Factor B), nest predation
(Factor C), and hook ingestion and
entanglement due to bycatch associated
with freshwater fishing (Factor E).
While historical activities that included
removal of turtles for consumption
through recreational and commercial
harvest (Factor B) continue to suppress
the viability of the species despite
current harvest prohibitions, the species
is currently well-distributed across most
of its historical range. There are
currently about 2,000 individuals
distributed throughout the entire
species’ range across southern Georgia
and northern Florida in the Suwannee
River basin (Service 2022, p. 27).
The magnitude of the threats acting
on the species were obtained through
expert elicitation. Incidental hooking
(i.e., recreational trot and limb lines,
fishing tackle, etc.) affects between 30–
75 percent of the species. Illegal harvest
or poaching across the basin ranges from
20–55 percent. Nest predation by native
and exotic species affected between 5–
10 percent of the spatial extent of the
species’ range (Service 2022, p. 28). Due
to the delayed age of sexual maturity
PO 00000
Frm 00041
Fmt 4700
Sfmt 4700
53521
and a generation time of about 28 years,
the species is slow to recover from
historical harvest pressures that reduced
the species’ viability. As the genus was
recently split, the specific impact of
large-scale harvest on Suwannee
alligator snapping turtles is unknown;
however, for Macrochelys temminckii,
22 years after M. temminckii
commercial harvest ended in Georgia,
surveys conducted during 2014 and
2015 in Georgia’s Flint River revealed
no significant change in abundance
since 1989 (King et al. 2016, entire). We
expect commercial harvest had a similar
impact on the Suwannee alligator
snapping turtle as it did on the alligator
snapping turtle. Thus, despite
prohibition of legal harvest of the
Suwannee alligator snapping turtle in
Georgia and Florida, the Suwannee
alligator snapping turtle population will
similarly be slow to recover.
Alligator snapping turtle populations
experienced severe depletion in the past
when these turtles were heavily
harvested, primarily for consumption,
prior to prohibitions (Factor B). This
past large-scale removal of large, adult
turtles continues to affect the current
demographics because the species has a
relatively long lifespan, late age to
maturity, and low fecundity with
production of a single clutch every 1 to
2 years. The current recruitment rate has
declined because of past commercial
harvest practices, which caused the
large-scale loss of adult females that
have the highest reproductive potential;
however, successful reproduction is
occurring. The species is not currently
impacted by commercial harvest;
however, the species’ resiliency is lower
than it was historically as a result of the
loss of reproductive females, low
juvenile survival, and the species’ lifehistory traits (long-lived, late age to
sexual maturity, low intrinsic growth
rate). The current estimated population
size of 2,000 turtles provides sufficient
contribution to the species’ current
viability through successful
reproduction, albeit at a lower
recruitment rate than historically. Thus,
after assessing the best available
information, we conclude that the
Suwannee alligator snapping turtle is
not currently in danger of extinction
throughout all of its range.
When evaluating the future viability
of the species to determine whether the
species may become an endangered
species within the foreseeable future
throughout its range, we found that the
threats currently acting on the species
are expected to continue across its range
into the future, resulting in greater
reduction of the number and
distribution of reproductive individuals.

53522
Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
We determined the appropriate
timeframe for assessing whether this
species is likely to become in danger of
extinction in the foreseeable future is 50
years. Based on our knowledge of the
species’ life history and the threats
acting on the species, this 50-year
timeframe provides a period for which
we can make reasonably reliable
predictions about the threats to the
species and the species’ response to
those threats. Additional information
regarding the model and future
scenarios is available under ‘‘Future
Conditions’’ in the SSA report (Service
2022, pp. 51–56).
This species is highly dependent
upon adult female survival to maintain
viable populations. Existing and
ongoing threats affecting adult female
survival are projected to reduce
recruitment to an extent that the single
population will continue to decline in
the foreseeable future. While there is
uncertainty regarding the rate at which
population declines will occur, these
threats are projected to drive the species
towards extinction unless reduced.
A key statutory difference between a
threatened and an endangered species is
the timing of when a species may be in
danger of extinction. As described
above, the Suwannee alligator snapping
turtle is not in danger of extinction
throughout its range at this time.
However, the best available information
shows that the species’ viability is
expected to decline with quasiextinction projected to occur within the
next 50 years under all modeled future
scenarios (Service 2022, p. 41). Based on
modeling results, which address
uncertainty regarding the extent and
severity of threats, resiliency is expected
to decline under all scenarios.
Regardless of the scenario, the projected
loss of resiliency with limited
representation and redundancy, across
the range of the species will place the
Suwannee alligator snapping turtle at
risk of extinction across all of its range
due to the inability of this species to
maintain a viable population in the
foreseeable future.
Recreational harvest of Macrochelys
spp. was prohibited in Georgia and
Florida, in 1992 and 2009, respectively,
and State-listed as threatened in Georgia
(in 1992) and Florida (in 2018). Based
on the projection of future conditions,
these threats will cause about a 20-year
shift in the species’ resiliency,
indicating these factors will act faster on
the generations in the foreseeable future.
Despite the implementation of the
conservation actions described earlier in
this final rule, the lag in the species’
response to historical over-harvesting
indicates other factors may be acting on

the species or additional conservation
actions are needed. The future
conditions projections, which include
three conservation-based scenarios,
based on the female-only matrix
population model indicates a 95 percent
decline in less than 50 years under the
most optimistic scenario. Therefore,
given the future projections in the
model, the species is likely to become
in danger of extinction within the
foreseeable future. Thus, after assessing
the best available information, we
conclude that Suwannee alligator
snapping turtle is likely to become an
endangered species within the
foreseeable future throughout all of its
range.
Status Throughout a Significant Portion
of Its Range
Under the Act and our implementing
regulations, a species may warrant
listing if it is in danger of extinction or
likely to become so within the
foreseeable future throughout all or a
significant portion of its range. The
court in Center for Biological Diversity
v. Everson, 435 F. Supp. 3d 69 (D.D.C.
2020) (Everson), vacated the provision
of the Final Policy on Interpretation of
the Phrase ‘‘Significant Portion of Its
Range’’ in the Endangered Species Act’s
Definitions of ‘‘Endangered Species’’
and ‘‘Threatened Species’’ (Final Policy;
79 FR 37578; July 1, 2014) that provided
if the Services determine that a species
is threatened throughout all of its range,
the Services will not analyze whether
the species is endangered in a
significant portion of its range.
Therefore, we proceed to evaluating
whether the species is endangered in a
significant portion of its range—that is,
whether there is any portion of the
species’ range for which both (1) the
portion is significant; and (2) the species
is in danger of extinction in that
portion. Depending on the case, it might
be more efficient for us to address the
‘‘significance’’ question or the ‘‘status’’
question first. We can choose to address
either question first. Regardless of
which question we address first, if we
reach a negative answer with respect to
the first question that we address, we do
not need to evaluate the other question
for that portion of the species’ range.
Following the court’s holding in
Everson, we now consider whether there
are any significant portions of the
species’ range where the species is in
danger of extinction now (i.e.,
endangered). In undertaking this
analysis for the Suwannee alligator
snapping turtle, we choose to address
the status question first. We consider
information pertaining to the
geographical distribution of both the
PO 00000
Frm 00042
Fmt 4700
Sfmt 4700
species and the threats that the species
faces to identify any portions of the
range where the species is endangered.
We evaluated the range of the
Suwannee alligator snapping turtle to
determine if the species is in danger of
extinction now in any portion of its
range.The range of a species can
theoretically be divided into portions in
an infinite number of ways. We focused
our analysis on portions of the species’
range that may meet the Act’s definition
of an endangered species. For the
Suwannee alligator snapping turtle, we
considered whether the threats to or
their effects on the species are greater in
any biologically meaningful portion of
the species’ range than in other portions
such that the species is in danger of
extinction now in that portion.
We examined the following threats:
illegal harvest (poaching), bycatch,
habitat alteration, nest predation, and
climate change, including cumulative
threats. We also considered the
cumulative effects acting on the species
with additional stressors such as
disease, parasites, and contaminants.
Due to the species’ low population size
due to historical overharvest and
limited redundancy and representation,
we find that additional stressors such as
disease, parasites, and contaminants
would add to the ongoing impacts to the
species from ongoing threats further
negatively affecting the species’
viability.
In the current condition analysis, as
described in the SSA report, expert
elicitation values were provided to
better understand the occurrence of the
threats and the collective amount of the
species’ range affected (Service 2022,
pp. 33–35). The impact of the threats
was estimated as a proxy for the
magnitude of the threats in terms of the
amount of the entire species’ range
affected; these estimates do not indicate
the spatial distribution of the threats.
Rather, they estimate the percentages of
the total amount of the species’ range
affected by each threat noted. Bycatch
from incidental hooking affects 30–75
percent of the species’ range, illegal
harvest affects 20–55 percent of the
species’ range, and nest predation
affects 5–10 percent of the species’
range; however, the impact of each
threat is spread out and not
concentrated in a manner that is causing
more significant declines in any
particular portion such that any portion
is likely to have a different status.
Therefore, we found no portion of the
Suwannee alligator snapping turtle’s
range where threats are impacting
individuals differently from how they
are affecting the species elsewhere in its
range, or where the biological condition
E:\FR\FM\27JNR1.SGM
27JNR1
Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
of the species differs from its condition
elsewhere in its range such that the
status of the species in that portion
differs from any other portion of the
species’ range.
Therefore, no portion of the species’
range provides a basis for determining
that the species is in danger of
extinction in a significant portion of its
range, and we determine that the
species is likely to become in danger of
extinction within the foreseeable future
throughout all of its range. This does not
conflict with the courts’ holdings in
Desert Survivors v. U.S. Department of
the Interior, 321 F. Supp. 3d 1011,
1070–74 (N.D. Cal. 2018) and Center for
Biological Diversity v. Jewell, 248 F.
Supp. 3d 946, 959 (D. Ariz. 2017)
because, in reaching this conclusion, we
did not apply the aspects of the Final
Policy, including the definition of
‘‘significant’’ that those court decisions
held to be invalid.

Determination of Status
Our review of the best scientific and
commercial data available indicates that
the Suwannee alligator snapping turtle
meets the Act’s definition of a
threatened species. Therefore, we are
listing the Suwannee alligator snapping
turtle as a threatened species in
accordance with sections 3(20) and
4(a)(1) of the Act.
Available Conservation Measures
Conservation measures provided to
species listed as endangered or
threatened species under the Act
include recognition as a listed species,
planning and implementation of
recovery actions, requirements for
Federal protection, and prohibitions
against certain practices. Recognition
through listing results in public
awareness, and conservation by Federal,
State, Tribal, and local agencies, foreign
governments, private organizations, and
individuals. The Act encourages
cooperation with the States and other
countries and calls for recovery actions
to be carried out for listed species. The
protection required by Federal agencies,
including the Service, and the
prohibitions against certain activities
are discussed, in part, below.
The primary purpose of the Act is the
conservation of endangered and
threatened species and the ecosystems
upon which they depend. The ultimate
goal of such conservation efforts is the
recovery of listed species, so that they
no longer need the protective measures
of the Act. Section 4(f) of the Act calls
for the Service to develop and
implement recovery plans for the
conservation of endangered and
threatened species. The goal of this
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
process is to restore listed species to a
point where they are secure, selfsustaining, and functioning components
of their ecosystems.
The recovery planning process begins
with development of a recovery outline
made available to the public soon after
a final listing determination. The
recovery outline guides the immediate
implementation of urgent recovery
actions while a recovery plan is being
developed. Recovery teams (composed
of species experts, Federal and State
agencies, nongovernmental
organizations, and stakeholders) may be
established to develop and implement
recovery plans. The recovery planning
process involves the identification of
actions that are necessary to halt and
reverse the species’ decline by
addressing the threats to its survival and
recovery. The recovery plan identifies
recovery criteria for review of when a
species may be ready for reclassification
from endangered to threatened
(‘‘downlisting’’) or removal from
protected status (‘‘delisting’’), and
methods for monitoring recovery
progress. Recovery plans also establish
a framework for agencies to coordinate
their recovery efforts and provide
estimates of the cost of implementing
recovery tasks. Revisions of the plan
may be done to address continuing or
new threats to the species, as new
substantive information becomes
available. When completed, the
recovery outline, draft recovery plan,
and the final recovery plan will be
available on our website (https://
ecos.fws.gov/ecp/species/10891), or
from our Florida Ecological Services
Field Office (see FOR FURTHER
INFORMATION CONTACT).
Implementation of recovery actions
generally requires the participation of a
broad range of partners, including other
Federal agencies, States, Tribes,
nongovernmental organizations,
businesses, and private landowners.
Examples of recovery actions include
habitat restoration of native vegetation,
research, captive propagation and
reintroduction, and outreach and
education. The recovery of many listed
species cannot be accomplished solely
on Federal lands because their range
may occur primarily or solely on nonFederal lands. To achieve recovery of
these species requires cooperative
conservation efforts on private, State,
and Tribal lands.
Once this species is listed, funding for
recovery actions will be available from
a variety of sources, including Federal
budgets, State programs, and cost share
grants for non-Federal landowners, the
academic community, and
nongovernmental organizations. In
PO 00000
Frm 00043

addition, pursuant to section 6 of the
Act, the States of Florida and Georgia
will be eligible for Federal funds to
implement management actions that
promote the protection or recovery of
the Suwannee alligator snapping turtle.
Information on our grant programs that
are available to aid species recovery can
be found at https://www.fws.gov/
service/financial-assistance.
Please let us know if you are
interested in participating in recovery
efforts for the Suwannee alligator
snapping turtle. Additionally, we invite
you to submit any new information on
this species whenever it becomes
available and any information you may
have for recovery planning purposes
(see FOR FURTHER INFORMATION CONTACT).
Section 7 of the Act is titled
Interagency Cooperation and mandates
all Federal action agencies to use their
existing authorities to further the
conservation purposes of the Act and to
ensure that their actions are not likely
to jeopardize the continued existence of
listed species or adversely modify
critical habitat. Regulations
implementing section 7 are codified at
50 CFR part 402.
Section 7(a)(2) states that each Federal
action agency shall, in consultation with
the Secretary, ensure that any action
they authorize, fund, or carry out is not
likely to jeopardize the continued
existence of a listed species or result in
the destruction or adverse modification
of designated critical habitat. Each
Federal agency shall review its action at
the earliest possible time to determine
whether it may affect listed species or
critical habitat. If a determination is
made that the action may affect listed
species or critical habitat, formal
consultation is required (50 CFR
402.14(a)), unless the Service concurs in
writing that the action is not likely to
adversely affect listed species or critical
habitat. At the end of a formal
consultation, the Service issues a
biological opinion, containing its
determination of whether the Federal
action is likely to result in jeopardy or
adverse modification.
Examples of discretionary actions for
the Suwannee alligator snapping turtle
that may be subject to consultation
procedures under section 7 are land
management or other landscape-altering
activities on Federal lands administered
by the Service, U.S. Forest Service, and
Department of Defense (Moody Air
Force Base) as well as actions on State,
Tribal, local, or private lands that
require a Federal permit (such as a
permit from the U.S. Army Corps of
Engineers under section 404 of the
Clean Water Act (33 U.S.C. 1251 et seq.)
or a permit from the Service under
E:\FR\FM\27JNR1.SGM
27JNR1
53524
Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
section 10 of the Act) or that involve
some other Federal action (such as
funding from the Federal Highway
Administration, Federal Aviation
Administration, or the Federal
Emergency Management Agency).
Federal actions not affecting listed
species or critical habitat—and actions
on State, Tribal, local, or private lands
that are not federally funded,
authorized, or carried out by a Federal
agency—do not require section 7
consultation. Federal agencies should
coordinate with the local Service Field
Office (see FOR FURTHER INFORMATION
CONTACT) with any specific questions on
section 7 consultation and conference
requirements.
It is the policy of the Services, as
published in the Federal Register on
July 1, 1994 (59 FR 34272), to identify
to the extent known at the time a
species is listed, specific activities that
will not be considered likely to result in
violation of section 9 of the Act. To the
extent possible, activities that will be
considered likely to result in violation
will also be identified in as specific a
manner as possible. The intent of this
policy is to increase public awareness of
the effect of a listing on proposed and
ongoing activities within the range of
the species. Although most of the
prohibitions in section 9 of the Act
apply to endangered species, sections
9(a)(1)(G) and 9(a)(2)(E) of the Act
prohibit the violation of any regulation
under section 4(d) pertaining to any
threatened species of fish or wildlife, or
threatened species of plant,
respectively. Section 4(d) of the Act
directs the Secretary to promulgate
protective regulations that are necessary
and advisable for the conservation of
threatened species. As a result, we
interpret our policy to mean that, when
we list a species as a threatened species,
to the extent possible, we identify
activities that will or will not be
considered likely to result in violation
of the protective regulations under
section 4(d) for that species.
Questions regarding whether specific
activities would constitute a violation of
section 9 of the Act should be directed
to the Florida Ecological Services Field
Office (see FOR FURTHER INFORMATION
CONTACT).

II. Protective Regulations Under
Section 4(d) of the Act
Background
Section 4(d) of the Act contains two
sentences. The first sentence states that
the Secretary shall issue such
regulations as she deems necessary and
advisable to provide for the
conservation of species listed as
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
threatened species. Conservation is
defined in the Act to mean the use of
all methods and procedures which are
necessary to bring any endangered
species or threatened species to the
point at which the measures provided
pursuant to the Act are no longer
necessary. Additionally, the second
sentence of section 4(d) of the Act states
that the Secretary may by regulation
prohibit with respect to any threatened
species any act prohibited under section
9(a)(1), in the case of fish or wildlife, or
section 9(a)(2), in the case of plants.
With these two sentences in section
4(d), Congress delegated broad authority
to the Secretary to determine what
protections would be necessary and
advisable to provide for the
conservation of threatened species, and
even broader authority to put in place
any of the section 9 prohibitions, for a
given species.
The courts have recognized the extent
of the Secretary’s discretion under this
standard to develop rules that are
appropriate for the conservation of a
species. For example, courts have
upheld, as a valid exercise of agency
authority, rules developed under section
4(d) that included limited prohibitions
against takings (see Alsea Valley
Alliance v. Lautenbacher, 2007 WL
2344927 (D. Or. 2007); Washington
Environmental Council v. National
Marine Fisheries Service, 2002 WL
511479 (W.D. Wash. 2002)). Courts have
also upheld 4(d) rules that do not
address all of the threats a species faces
(see State of Louisiana v. Verity, 853
F.2d 322 (5th Cir. 1988)). As noted in
the legislative history when the Act was
initially enacted, ‘‘once an animal is on
the threatened list, the Secretary has an
almost infinite number of options
available to [her] with regard to the
permitted activities for those species.
[She] may, for example, permit taking,
but not importation of such species, or
[s]he may choose to forbid both taking
and importation but allow the
transportation of such species’’ (H.R.
Rep. No. 412, 93rd Cong., 1st Sess.
1973).
The provisions of this species’
protective regulations under section 4(d)
of the Act are one of many tools that we
will use to promote the conservation of
the Suwannee alligator snapping turtle.
Nothing in 4(d) rules change in any way
the recovery planning provisions of
section 4(f) of the Act, the consultation
requirements under section 7 of the Act,
or the ability of the Service to enter into
partnerships for the management and
protection of the Suwannee alligator
snapping turtle. As mentioned
previously in Available Conservation
Measures, Section 7(a)(2) of the Act
PO 00000
Frm 00044
Fmt 4700
Sfmt 4700
requires Federal agencies, including the
Service, to ensure that any action they
authorize, fund, or carry out is not likely
to jeopardize the continued existence of
any endangered species or threatened
species or result in the destruction or
adverse modification of designated
critical habitat of such species. These
requirements are the same for a
threatened species regardless of what is
included in its 4(d) rule.
Section 7 consultation is required for
Federal actions that ‘‘may affect’’ a
listed species regardless of whether take
caused by the activity is prohibited or
excepted by a 4(d) rule (‘‘blanket rule’’
or species-specific 4(d) rule). A 4(d) rule
does not change the process and criteria
for informal or formal consultations and
does not alter the analytical process
used for biological opinions or
concurrence letters. For example, as
with an endangered species, if a Federal
agency determines that an action is ‘‘not
likely to adversely affect’’ a threatened
species, this will require the Service’s
written concurrence (50 CFR 402.13(c).
Similarly, if a Federal agency
determines that an action is ‘‘likely to
adversely affect’’ a threatened species,
the action will require formal
consultation and the formulation of a
biological opinion (50 CFR 402.14(a)).
Because consultation obligations and
processes are unaffected by 4(d) rules,
we may consider developing tools to
streamline future intra-Service and
inter-Agency consultations for actions
that result in forms of take that are not
prohibited by the 4(d) rule (but that still
require consultation). These tools may
include consultation guidance,
Information for Planning and
Consultation (IPaC) effects
determination keys, template language
for biological opinions, or programmatic
consultations.
Provisions of the 4(d) Rule
Exercising the Secretary’s authority
under section 4(d) of the Act, we have
developed a rule that is designed to
address the Suwannee alligator
snapping turtle’s conservation needs. As
discussed previously in Summary of
Biological Status and Threats, we have
concluded that the Suwannee alligator
snapping turtle is likely to become in
danger of extinction within the
foreseeable future primarily due to
illegal harvest (poaching), nest
predation, and bycatch-related incidents
of hook ingestion and entanglement due
recreational fishing of freshwater fish.
There are other activities that could
affect the species and its habitat if they
occur in areas occupied by the species,
such as impacts to water quality and
quantity.

27JNR1
lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
Due to the life-history characteristics
of the Suwannee alligator snapping
turtle, specifically delayed maturity,
long generation times, and relatively
low reproductive output, this species
cannot sustain significant collection
from the wild, especially of adult
females (Reed et al. 2002, pp. 8–12). An
adult female harvest rate of more than
2 percent per year is considered
unsustainable, and harvest of this
magnitude or greater will result in
significant local population declines
(Reed et al. 2002, p. 9). Although both
Florida and Georgia prohibit
commercial and recreational harvest of
Suwannee alligator snapping turtles,
due to the species’ demography, the
overall population has not recovered
from prior extensive loss of individuals
due to past over-exploitation.
Habitat alteration is also a concern for
the Suwannee alligator snapping turtle,
as the species is endemic to the
Suwannee River basin and its river
ecosystems, including tributary
waterbodies and associated wetland
habitats (e.g., swamps, lakes, reservoirs,
etc.), where structure (e.g., tree root
masses, stumps, submerged trees, etc.)
and a high percentage of canopy cover
is more often selected over open water
(Howey and Dinkelacker 2009, p. 589).
Suwannee alligator snapping turtles
spend the majority of their time in
aquatic habitat; overland movements are
generally restricted to nesting females
and juveniles moving from the nest to
water (Reed et al. 2002, p. 5). The
primary causes for habitat alteration
include actions that change hydrologic
conditions to the extent that dispersal
and genetic interchange are impeded.
Some examples of activities that may
alter the habitat include dredging,
deadhead logging, clearing and
snagging, removal of riparian cover,
channelization, in-stream activities that
result in stream bank erosion and
siltation (e.g., stream crossings, bridge
replacements, flood control structures,
etc.), and changes in land use within the
riparian zone of waterbodies (e.g.,
clearing land for agriculture). Deadhead
logs and fallen riparian woody debris
provide refugia during low-water
periods (Enge et al. 2014, p. 40), resting
areas for all life stages (Ewert et al. 2006,
p. 62), and important feeding areas for
hatchlings and juveniles. The species’
habitat needs concentrate around a
freshwater ecosystem that supplies both
shallower water for hatchlings and
juveniles and deeper water for adults,
with associated forested habitat that is
free from inundation for nesting and
that provides structure within the
waterbody.

Jkt 262001
Regulating certain activities and take
associated with other activities under
this 4(d) rule will prevent continued
declines in population abundance, and
decrease synergistic, negative effects
from other threats.
Section 4(d) requires the Secretary to
issue such regulations as she deems
necessary and advisable to provide for
the conservation of each threatened
species and authorizes the Secretary to
include among those protective
regulations any of the prohibitions that
section 9(a)(1) of the Act prescribes for
endangered species. We are not required
to make a ‘‘necessary and advisable’’
determination when we apply or do not
apply specific section 9 prohibitions to
a threatened species (In re: Polar Bear
Endangered Species Act Listing and 4(d)
Rule Litigation, 818 F. Supp. 2d 214,
228 (D.D.C. 2011) (citing Sweet Home
Chapter of Cmtys. for a Great Or. v.
Babbitt, 1 F.3d 1, 8 (D.C. Cir. 1993),
rev’d on other grounds, 515 U.S. 687
(1995))). Nevertheless, even though we
are not required to make such a
determination, we have chosen to be as
transparent as possible and explain
below why we find that the protections,
prohibitions, and exceptions in this rule
as a whole satisfy the requirement in
section 4(d) of the Act to issue
regulations deemed necessary and
advisable to provide for the
conservation of the Suwannee alligator
snapping turtle.
The protective regulations for
Suwannee alligator snapping turtle
incorporate prohibitions from section
9(a)(1) to address the threats to the
species. The prohibitions of section
9(a)(1) of the Act, and implementing
regulations codified at 50 CFR 17.21,
make it illegal for any person subject to
the jurisdiction of the United States to
commit, to attempt to commit, to solicit
another to commit or to cause to be
committed any of the following acts
with regard to any endangered wildlife:
(1) import into, or export from, the
United States; (2) take (which includes
harass, harm, pursue, hunt, shoot,
wound, kill, trap, capture, or collect)
within the United States, within the
territorial sea of the United States, or on
the high seas; (3) possess, sell, deliver,
carry, transport, or ship, by any means
whatsoever, any such wildlife that has
been taken illegally; (4) deliver, receive,
carry, transport, or ship in interstate or
foreign commerce, by any means
whatsoever and in the course of
commercial activity; or (5) sell or offer
for sale in interstate or foreign
commerce. This protective regulation
includes all of these prohibitions
because the Suwannee alligator
snapping turtle is at risk of extinction in
PO 00000
Frm 00045
Fmt 4700
Sfmt 4700
53525
the foreseeable future and putting these
prohibitions in place will help to
prevent further declines, preserve the
species’ remaining population, slow its
rate of decline, and decrease synergistic,
negative effects from other ongoing or
future threats.
In particular, this 4(d) rule will
provide for the conservation of the
Suwannee alligator snapping turtle by
prohibiting the following activities,
unless they fall within specific
exceptions or are otherwise authorized
or permitted: importing or exporting;
take; possession and other acts with
unlawfully taken specimens; delivering,
receiving, carrying, transporting, or
shipping in interstate or foreign
commerce in the course of commercial
activity; or selling or offering for sale in
interstate or foreign commerce.
Under the Act, ‘‘take’’ means to
harass, harm, pursue, hunt, shoot,
wound, kill, trap, capture, or collect, or
to attempt to engage in any such
conduct. Some of these provisions have
been further defined in regulation at 50
CFR 17.3. Take can result knowingly or
otherwise, by direct and indirect
impacts, intentionally or incidentally.
Regulating take of the species resulting
from activities including, but not
limited to, illegal harvest (poaching),
hook ingestions and entanglement due
to bycatch associated with irresponsible
commercial and recreational fishing of
some species of freshwater fish
(particularly as a result of unlawful
activities or abandonment of
equipment), and habitat alteration will
provide for the conservation of the
species. Therefore, we are prohibiting
take of the Suwannee alligator snapping
turtle, except for take resulting from
those actions and activities specifically
excepted by the 4(d) rule. Exceptions to
the prohibition on take include the
general exceptions to the prohibition on
take of endangered wildlife, as set forth
in 50 CFR 17.21 and additional
exceptions, as described below.
Despite these prohibitions regarding
threatened species, we may under
certain circumstances issue permits to
carry out one or more otherwise
prohibited activities, including those
described above. The regulations that
govern permits for threatened wildlife
state that the Director may issue a
permit authorizing any activity
otherwise prohibited with regard to
threatened species. These include
permits issued for the following
purposes: for scientific purposes, to
enhance propagation or survival, for
economic hardship, for zoological
exhibition, for educational purposes, for
incidental taking, or for special
purposes consistent with the purposes
E:\FR\FM\27JNR1.SGM

53526
Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
of the Act (50 CFR 17.32). The statute
also contains certain exemptions from
the prohibitions, which are found in
sections 9 and 10 of the Act.
In addition, to further the
conservation of the species, any
employee or agent of the Service, any
other Federal land management agency,
the National Marine Fisheries Service, a
State conservation agency, or a federally
recognized Tribe, who is designated by
their agency or Tribe for such purposes,
may, when acting in the course of their
official duties, take threatened wildlife
without a permit if such action is
necessary to: (i) Aid a sick, injured, or
orphaned specimen; or (ii) Dispose of a
dead specimen; or (iii) Salvage a dead
specimen that may be useful for
scientific study; or (iv) Remove
specimens that constitute a
demonstrable but nonimmediate threat
to human safety, provided that the
taking is done in a humane manner; the
taking may involve killing or injuring
only if it has not been reasonably
possible to eliminate such threat by live
capturing and releasing the specimen
unharmed, in an appropriate area.
We recognize the special and unique
relationship that we have with our State
natural resource agency partners in
contributing to conservation of listed
species. State agencies often possess
scientific data and valuable expertise on
the status and distribution of
endangered, threatened, and candidate
species of wildlife and plants. State
agencies, because of their authorities
and their close working relationships
with local governments and
landowners, are in a unique position to
assist us in implementing all aspects of
the Act. In this regard, section 6 of the
Act provides that we must cooperate to
the maximum extent practicable with
the States in carrying out programs
authorized by the Act. Therefore, any
qualified employee or agent of a State
conservation agency that is a party to a
cooperative agreement with us in
accordance with section 6(c) of the Act,
who is designated by his or her agency
for such purposes, will be able to
conduct activities designed to conserve
the Suwannee alligator snapping turtle
that may result in otherwise prohibited
take without additional authorization.
The 4(d) rule will also provide for the
conservation of the species by allowing
exceptions that incentivize conservation
actions or that, while they may have
some minimal level of take of the
Suwannee alligator snapping turtle, are
not expected to rise to the level that
would have a negative impact (i.e.,
would have only de minimis impacts)
on the species’ conservation. The
exceptions to these prohibitions include
VerDate Sep<11>2014
15:47 Jun 26, 2024
Jkt 262001
take resulting from the following
activities forest management practices
that use State-approved best
management practices (described below)
that are expected to have negligible
impacts to the Suwannee alligator
snapping turtle and its habitat.
Pesticide and Herbicide Use: Pesticide
and herbicide application was included
as an exception in the proposed 4(d)
rule and after further consideration, we
are removing this exception. When
considering pesticide use, we note that
the EPA has not consulted on most
pesticide registrations to date, so
excepting take solely based on user
compliance with label directions and
State and local regulations is not
appropriate in all situations. The
Service will continue to coordinate with
EPA on further pesticide consultation
and registration efforts. We have
reviewed comments provided during
the public comment period on the
exception to the prohibition of take
related to pesticide use and the impact
of pesticide use on the Suwannee
alligator snapping turtle. We have
determined that the exception for
pesticide use described in the preamble
of the proposed rule was not necessary
and advisable for the conservation of the
species and have therefore not included
that exception in this final rule.
Forest Management Practices: Forest
management practices that implement
State-approved BMPs designed to
protect water quality and stream and
riparian habitat will avoid or minimize
the effects of habitat alterations in areas
that support Suwannee alligator
snapping turtles. We considered that
forest management activities may result
in removal of riparian cover or forested
habitat, changes in land use within the
riparian zone, or stream bank erosion
and/or siltation. We recognize that
forest management practices are widely
implemented in accordance with Stateapproved BMPs (as reviewed by Cristan
et al. 2018, entire), and the adherence to
these BMPs broadly protects water
quality, particularly related to
sedimentation (as reviewed by Cristan et
al. 2016, entire; Warrington et al. 2017,
entire; and Schilling et al. 2021, entire),
to an extent that does not impair the
species’ conservation. Forest
landowners who properly implement
those BMPs are helping conserve the
Suwannee alligator snapping turtle, and
this 4(d) rule is an incentive for all
landowners to properly implement
applicable State-approved BMPs to
avoid any take implications. Further,
those forest landowners who are thirdparty-certified (attesting to the
sustainable management of a working
forest) to a credible forest management
PO 00000
Frm 00046
Fmt 4700
Sfmt 4700
standard are providing audited certainty
that BMP implementation is taking
place across the landscape.
Summary: Thus, under this final 4(d)
rule, incidental take associated with
forest management practices that use
State-approved BMPs to protect water
quality and stream and riparian habitat
is excepted from the prohibitions.
III. Critical Habitat
Background
Section 4(a)(3) of the Act requires
that, to the maximum extent prudent
and determinable, we designate a
species’ critical habitat concurrently
with listing the species. Critical habitat
is defined in section 3 of the Act as:
(1) The specific areas within the
geographical area occupied by the
species, at the time it is listed in
accordance with the Act, on which are
found those physical or biological
features
(a) Essential to the conservation of the
species, and
(b) Which may require special
management considerations or
protection; and
(2) Specific areas outside the
geographical area occupied by the
species at the time it is listed, upon a
determination that such areas are
essential for the conservation of the
species.
Our regulations at 50 CFR 424.02
define the geographical area occupied
by the species as an area that may
generally be delineated around species’
occurrences, as determined by the
Secretary (i.e., range). Such areas may
include those areas used throughout all
or part of the species’ life cycle, even if
not used on a regular basis (e.g.,
migratory corridors, seasonal habitats,
and habitats used periodically, but not
solely by vagrant individuals).
Conservation, as defined under
section 3 of the Act, means to use and
the use of all methods and procedures
that are necessary to bring an
endangered or threatened species to the
point at which the measures provided
pursuant to the Act are no longer
necessary. Such methods and
procedures include, but are not limited
to, all activities associated with
scientific resources management such as
research, census, law enforcement,
habitat acquisition and maintenance,
propagation, live trapping, and
transplantation, and, in the
extraordinary case where population
pressures within a given ecosystem
cannot be otherwise relieved, may
include regulated taking.
Critical habitat receives protection

Federal Register / Vol. 89, No. 124 / Thursday, June 27, 2024 / Rules and Regulations
requirement that Federal agencies
ensure, in consultation with the Service,
that any action they authorize, fund, or
carry out is not likely to result in the
destruction or adverse modification of
critical habitat. The designation of
critical habitat does not affect land
ownership or establish a refuge,
wilderness, reserve, preserve, or other
conservation area. Such designation also
does not allow the government or public
to access private lands. Such
designation does not require
implementation of restoration, recovery,
or enhancement measures by nonFederal landowners. Rather, designation
requires that, where a landowner
requests Federal agency funding or
authorization for an action that may
affect an area designated as critical
habitat, the Federal agency consult with
the Service under section 7(a)(2) of the
Act. If the action may affect the listed
species itself (such as for occupied
critical habitat), the Federal action
agency would have already been
required to consult with the Service
even absent the critical habitat
designation because of the requirement
to ensure that the action is not likely to
jeopardize the continued existence of
the species. Even if the Service were to
conclude after consultation that the
proposed activity is likely to result in
destruction or adverse modification of
the critical habitat, the Federal action
agency and the landowner are not
required to abandon the proposed
activity, or to restore or recover the
species; instead, they must implement
‘‘reasonable and prudent alternatives’’
to avoid destruction or adverse
modification of critical habitat.
Under the first prong of the Act’s
definition of critical habitat, areas
within the geographical area occupied
by the species at the time it was listed
are included in a critical habitat
designation if they contain physical or
biological features (1) which are
essential to the conservation of the
species and (2) which may require
special management considerations or
protection. For these areas, critical
habitat designations identify, to the
extent known using the best scientific
data available, those physical or
biological features that are essential to
the conservation of the species (such as
space, food, cover, and protected
habitat).
Under the second prong of the Act’s
definition of critical habitat, we can
designate critical habitat in areas
outside the geographical area occupied
by the species at the time it is listed,
upon a determination that such areas
are essential for the conservation of the
species.

Section 4 of the Act requires that we
designate critical habitat on the basis of
the best scientific data available.
Further, our Policy on Information
Standards Under the Endangered
Species Act (published in the Federal
Register on July 1, 1994 (59 FR 34271)),
the Information Quality Act (section 515
of the Treasury and General
Government Appropriations Act for
Fiscal Year 2001 (Pub. L. 106–554; H.R.
5658)), and our associated Information
Quality Guidelines provide criteria,
establish procedures, and provide
guidance to ensure that our decisions
are based on the best scientific data
available. They require our biologists, to
the extent consistent with the Act and
with the use of the best scientific data
available, to use primary and original
sources of information as the basis for
recommendations to designate critical
habitat.
Prudency Determination
Section 4(a)(3) of the Act, as
amended, and implementing regulations
(50 CFR 424.12) require that, to the
maximum extent prudent and
determinable, the Secretary shall
designate critical habitat at the time the
species is determined to be an
endangered species or a threatened
species. On April 5, 2024, we published
a final rule that revised our regulations
at 50 CFR part 424 to further clarify
when designation of critical habitat may
not be prudent (89 FR 24300). Our
regulations (50 CFR424.12(a)(1)) state
that designation of critical habitat may
not be prudent in circumstances such
as, but not limited to, the following:
(i) The species is threatened by taking
or other human activity and
identification of critical habitat can be
expected to increase the degree of such
threat to the species;
(ii) The present or threatened
destruction, modification, or
curtailment of a species’ habitat or range
is not a threat to the species;
(iii) Areas within the jurisdiction of
the United States provide no more than
negligible conservation value, if any, for
a species occurring primarily outside
the jurisdiction of the United States; or
(iv) No areas meet the definition of
critical habitat.
In the April 7, 2021, proposed rule (86
FR 18014), we determined that
designation of critical habitat would not
be prudent. However, we invited public
comment and requested information on
the factors that the regulations identify
as reasons why designation of critical
habitat may be not prudent, and the
extent to which designation might
increase threats to the species, as well
as the possible benefits of critical
PO 00000

53527
habitat designation to the Suwannee
alligator snapping turtle.
During the comment period, we did
not receive any comments that caused
us to change the not-prudent
determination or our rationale for it.
The not-prudent determination for the
proposed rule was based on increasing
the threat of collection as described in
50 CFR 424.12(a)(1)(i). This component
of the latest regulatory language has not
changed from the regulatory language
used in the proposed rule. The nonprudent determination for this final rule
is the same as the proposed because the
threat of collection is one of the factors
in determining prudency that remained
consistent in the previous regulations
and the current regulations
Therefore, after review and
consideration of the comments we
received, we now make a final
determination that the designation of
critical habitat is not prudent, in
accordance with 50 CFR 424.12(a)(1),
because the Suwannee alligator
snapping turtle faces the threat of
poaching, and designation can
reasonably be expected to increase the
degree of this threat to the species by
making location information more
readily available.
Required Determinations
National Environmental Policy Act (42
U.S.C. 4321 et seq.)
Regulations adopted pursuant to
section 4(a) of the Act are exempt from
the National Environmental Policy Act
(NEPA; 42 U.S.C. 4321 et seq.) and do
not require an environmental analysis
under NEPA. We published a notice
outlining our reasons for this
determination in the Federal Register
on October 25, 1983 (48 FR 49244). This
includes listing, delisting, and
reclassification rules, as well as critical
habitat designations and speciesspecific protective regulations
promulgated concurrently with a
decision to list or reclassify a species as
threatened. The courts have upheld this
position (e.g., Douglas County v.
Babbitt, 48 F.3d 1495 (9th Cir. 1995)
(critical habitat); Center for Biological
Diversity v. U.S. Fish and Wildlife
Service, 2005 WL 2000928 (N.D. Cal.
Aug. 19, 2005) (concurrent 4(d) rule)).

Governments), and the Department of
the Interior’s manual at 512 DM 2, we
readily acknowledge our responsibility
to communicate meaningfully with
federally recognized Tribes on a
government-to-government basis. In
accordance with Secretary’s Order 3206
of June 5, 1997 (American Indian Tribal
Rights, Federal-Tribal Trust
Responsibilities, and the Endangered
Species Act), we readily acknowledge
our responsibilities to work directly
with Tribes in developing programs for
healthy ecosystems, to acknowledge that
Tribal lands are not subject to the same
controls as Federal public lands, to
remain sensitive to Indian culture, and
to make information available to Tribes.
Upon the initiation of the SSA
process, we contacted Tribes within the
range of Suwannee alligator snapping
turtle and additional Tribes of interest
to inform them of our intent to complete
an SSA for the species that would
inform the species’ 12-month finding.

Endangered and Threatened Wildlife and Plants; Threatened Status
for the Suwannee Alligator Snapping Turtle with a Section 4(d) Rule
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), determine
threatened species status under the Endangered Species Act of 1973
(Act), as amended, for the Suwannee alligator snapping turtle
(Macrochelids suwanniensis), a large, freshwater turtle species from
the Suwannee River basin in Florida and Georgia. This rule adds the
species to the List of Endangered and Threatened Wildlife. We also
finalize a rule issued under the authority of section 4(d) of the Act
that provides measures that are necessary and advisable to provide for
the conservation of this species. We have determined that designating
critical habitat for the Suwannee alligator snapping turtle is not
prudent.
DATES: This rule is effective July 29, 2024.
ADDRESSES: This final rule is available on the internet at https://www.regulations.gov under Docket No. FWS-R4-ES-2021-0007 and on the
Service's Environmental Conservation Online System (ECOS) species page

SUPPLEMENTARY INFORMATION:
Executive Summary
Why we need to publish a rule. Under the Act, a species warrants
listing if it meets the definition of an endangered species (in danger
of extinction throughout all or a significant portion of its range) or
a threatened species (likely to become an endangered species within the
foreseeable future throughout all or a significant portion of its
range). If we determine that a species warrants listing, we must list
the species promptly and designate the species' critical habitat to the
maximum extent prudent and determinable.We have determined that the
Suwannee alligator snapping turtle meets the Act's definition of a
threatened species; therefore, we are listing it as such. Listing a
species as an endangered or threatened species can be completed only by
issuing a rule through the Administrative Procedure Act rulemaking
process (5 U.S.C. 551 et seq.).
What this document does. This rule lists the Suwannee alligator
snapping turtle (Macrochelys suwanniensis) as a threatened species and
finalizes the rule issued under the authority of section 4(d) of the
Act (the ``4(d) rule'') that provides measures that are necessary and
advisable to provide for the conservation of this species.
The basis for our action. Under the Act, we may determine that a
species is an endangered or threatened species based on any of five
factors: (A) The present or threatened destruction, modification, or
curtailment of its habitat or range; (B) overutilization for
commercial, recreational, scientific, or educational purposes; (C)
disease or predation; (D) the inadequacy of existing regulatory
mechanisms; or (E) other natural or manmade factors affecting its
continued existence. We have determined that the primary threats acting
on the Suwannee alligator snapping turtle include illegal harvest and
collection (Factor B), nest predation (Factor C), and hook ingestion
and entanglement due to bycatch associated with freshwater fishing
(Factor E).
Previous Federal Actions
Please refer to the April 7, 2021, proposed rule (86 FR 18014) for
a detailed description of previous Federal actions concerning the
Suwannee alligator snapping turtle.
Peer Review
A species status assessment (SSA) team prepared an SSA report,
version 1.0, for the Suwannee alligator snapping turtle (Service 2020,
entire). The SSA team was composed of Service biologists, in
consultation with other species experts. The SSA report represents a
compilation of the best scientific and commercial data available
concerning the status of the species, including the impacts of past,
present, and future factors (both negative and beneficial) affecting
the species.
In accordance with our joint policy on peer review published in the
Federal Register on July 1, 1994 (59 FR 34270), and our August 22,
2016, memorandum updating and clarifying the role of peer review of
listing actions under the Act, we sought peer review of the SSA report
version 1.0 (Service 2020, entire). As discussed in the proposed rule,
we sent the SSA report to four independent peer reviewers and received
responses from one reviewer. The peer review can be viewed at https://www.regulations.gov and at our Florida Ecological Services Field Office
(see FOR FURTHER INFORMATION CONTACT). In preparing the proposed rule,
we incorporated the results of this review, as appropriate, into the
SSA report, which was the foundation for the proposed rule and this
final rule. A summary of the peer review comments and our responses can
be found in in the Summary of Comments and Recommendations below.
Summary of Changes From the Proposed Rule
In preparing this final rule, we reviewed and fully considered
comments we received on our April 7, 2021, proposed rule to list the
Suwannee alligator snapping turtle as a threatened species with a 4(d)
rule. We updated the Suwannee alligator snapping turtle SSA report (to
version 1.2 (Service 2022, entire) based on comments and additional
information provided during the proposed rule's
[[Page 53508]]
comment period. Those updates are reflected in this final rule, as
follows:
1. We update the description of the species' representation and
redundancy and clarify these conservation principles to provide a
better understanding of the species' current and future viability.
2. We include new information provided during the comment period
regarding the effectiveness of best management practices (BMPs)
associated with forest management practices. We added a discussion on
ways in which the implementation of such BMPs provides conservation
benefits to the species.
3. For the 4(d) rule, we are not including the exception from
prohibitions associated with Federal and State captive-breeding
programs to support conservation efforts for wild populations. We
determined this provision is redundant with the exception under 50 CFR
17.31(b), which is already included in the 4(d) rule.
4. For the 4(d) rule, we are not including the exception from the
prohibitions regarding incidental take resulting from herbicide/
pesticide use from this final rule. We do not have enough information
about the types or amounts of pesticides that may be applied in areas
where Suwannee alligator snapping turtle occurs to be able assess the
future impacts to the species. The additional materials provided during
the public comment period indicate impacts to other turtle species from
pesticide use occurs (Bishop et al. 1991, entire; Sparling et al. 2006,
entire; Kittle et al. 2018, entire). Therefore, including this
exception to incidental take may not provide for the conservation of
the species. Further, we note that the Environmental Protection Agency
(EPA) has not consulted on most pesticide registrations to date, so
excepting take solely based on user compliance with label directions
and State and local regulations EPA has not consulted on most pesticide
registrations to date and is not appropriate in this situation.
Retaining this exception in the absence of consultation on a specific
pesticide registration may create confusion regarding the consideration
of these impacts and whether Federal regulatory processes apply to
these activities. It was not our intent to supersede the consultation
on the pesticide registration nor other Federal activities.
5. For the 4(d) rule, we revise the text of the exception from
incidental take prohibition resulting from forestry management
practices. We remove the terms ``silviculture and silvicultural
practices'' and replace them with ``forest management practices'' to
clarify the exception to incidental take prohibitions, as this is more
appropriate for the intent and purpose of the rule.
6. For the 4(d) rule, we are not including the exception from
incidental take prohibition resulting from construction, operation, and
maintenance activities that occur near and in a stream. We determined
this exception is too vague to meaningfully provide conservation
benefits to the species. In addition, this exception could have caused
confusion regarding whether Federal or State regulatory processes apply
to these activities. Many activities occurring near or in a stream
require permits or project review by Federal or State agencies, and
including this exception could have been interpreted as removing these
requirements, which was not our intention.
7. For the 4(d) rule, we are not including the exception from
incidental take prohibition resulting from maintenance dredging
activities that occur in the previously disturbed portion of a
maintained channel. We determined this exception is too vague to
meaningfully provide conservation benefits to the species. In addition,
dredging activities to promote river traffic can cause temporary
turbidity, leading to decreased ability to see and ambush prey species;
the removal of underwater snags, which could reduce prey availability
by eliminating areas where prey is found (e.g., congregation areas,
nursery areas, feeding areas); and the filling of scour areas used to
ambush prey. In addition, this exception could have caused confusion
regarding whether Federal or State regulatory processes apply to these
activities. All in-water work, including dredging in previously dredged
area, requires appropriate State and Federal permits, so including this
exception could have been interpreted as removing this requirement,
which was not our intention.
8. For the 4(d) rule, we are not including the exception from
prohibitions for Tribal employees and State-licensed wildlife
rehabilitation facilities. A provision under 50 CFR 17.31(b)(1) now
extends to federally recognized Tribes the exceptions to prohibitions
for threatened wildlife to aid, salvage, or dispose of threatened
wildlife and is already included in this 4(d) rule. We also are not
including the exception from prohibitions for State-licensed wildlife
rehabilitation facilities because it is redundant with the provision at
50 CFR 17.21(c)(3), which allows take of endangered wildlife without a
permit if such action is necessary to aid a sick, injured, or orphaned
specimen without additional authorization, which is also already
included in the 4(d) rule.
9. We update information to reflect that the alligator snapping
turtle (Macrochelys temminckii) was transferred from Appendix III of
CITES to Appendix II (CITES 2023, pp. 45-46).
10. We make minor, nonsubstantive editorial corrections and
revisions for clarity and consistency throughout this document.
The information we received during the comment period on our April
7, 2021, proposed rule did not change our determination that the
Suwannee alligator snapping turtle meets the Act's definition of a
threatened species. The information provided through the comment period
also did not cause us to revise our determination that designation of
critical habitat for the Suwannee alligator snapping turtle is not
prudent.
Summary of Comments and Recommendations
In the proposed rule published on April 7, 2021 (86 FR 18014), we
requested that all interested parties submit written comments on the
proposal by June 7, 2021. We also contacted appropriate Federal and
State agencies, scientific experts and organizations, and other
interested parties and invited them to comment on the proposed listing
determination and proposed 4(d) rule. A newspaper notice inviting
general public comment was published in the Gainesville Sun on April
21, 2021. We did not receive any requests for a public hearing. All
substantive information provided during the comment period either has
been incorporated directly into the final rule or is addressed below.
As discussed in Peer Review above, we received a response from one
peer reviewer on the draft SSA report. As discussed above, because we
conducted this peer review prior to the publication of our proposed
rule, we had already incorporated all applicable peer review comments
into version 1.1 of the SSA report, which was the foundation for the
proposed rule and this final rule and ultimately into the latest
version of the SSA report, version 1.2 (Service 2022, entire). The peer
reviewer generally concurred with our methods and conclusions and
provided additional information regarding seed dispersal by the common
snapping turtle (Chelydra sepentina). We added the information provided
by the peer reviewer into the SSA report, version 1.1 (Service 2021,
entire) as appropriate.
[[Page 53509]]
Public Comments
We received 34 public comments in response to our April 7, 2021,
proposed rule. We reviewed all comments we received during the public
comment period for substantive issues and new information regarding the
proposed rule. Seventeen comments provided substantive comments or new
information concerning the proposed listing of the species' status,
proposed 4(d) rule, and prudency determination for critical habitat for
the Suwannee alligator snapping turtle. Below, we provide a summary of
public comments we received; however, comments that we incorporated as
changes into the final rule, comments outside the scope of the proposed
rule, and those without supporting information did not warrant an
explicit response and, thus, are not presented here. Identical or
similar comments have been consolidated and a single response provided.
Comments From States
(1) Comment: The Georgia Department of Natural Resources (GDNR),
Wildlife Resources Division commented that occasional observations by
biologists and anglers indicate that ensnarement and/or hook ingestion
by Suwannee alligator snapping turtle may occur as a result of legal
fishing methods in Georgia, and research is needed to further quantify
population impacts of incidental take on this species. The GDNR also
recommended the rule place greater emphasis on promoting practices and
regulations to reduce impacts to the Suwannee alligator snapping turtle
from abandoned fishing gear.
Our Response: We plan to work with both GDNR and the Florida Fish
and Wildlife Conservation Commission (FWC) to better understand impacts
from legal and abandoned fishing gear. As discussed in our April 7,
2021, proposed rule, turtle bycatch from legal recreational and
commercial fishing with hoop nets and trot lines (and varieties
including jug lines, bush hooks, and limb lines) is a concern for the
conservation of the species due to its effects on species abundance,
particularly in light of the species' life-history traits. It is
important to ensure that fishing activities take into consideration the
need to prevent accidental turtle deaths from the use of such fishing
gear, and we will work with our State partners to identify measures and
revisions to existing State fishing regulations to reduce bycatch of
Suwannee alligator snapping turtle. Given we did not receive
information during the comment period for bycatch reduction techniques,
we did not include an exception for incidental take of the Suwannee
alligator snapping turtle resulting from bycatch from otherwise lawful
recreational and commercial fishing in our final 4(d) rule. Therefore,
take of the species resulting from bycatch activities is prohibited in
the 4(d) rule.
Public Comments Categorized by Topic
Species' Status
(2) Comment: One commenter stated their view that the Suwannee
alligator snapping turtle should be listed as an endangered species
rather than a threatened species.
Our Response: An endangered species is one that is in danger of
extinction throughout all or a significant portion of its range. Based
on the best available information as described in the SSA report
(Service 2022, entire), we do not find that the Suwannee alligator
snapping turtle is currently in danger of extinction throughout all or
a significant portion of its range. The current condition of the
species provides for sufficient resiliency, redundancy, and
representation such that it is not currently in danger of extinction
(see Determination of Suwannee Alligator Snapping Turtle Status in the
proposed listing rule (86 FR 18014, April 7, 2021, at pp. 18026-18028)
and below in this final rule). When evaluating the species' status
based on the threats and the species' response to the threats in the
future, the species meets the Act's definition of a threatened species
because it is at risk of becoming an endangered species within the
foreseeable future throughout all of its range. The commenters did not
provide any new information regarding threats to the Suwannee alligator
snapping turtle or its current status that was not already considered
in the SSA report (Service 2021, entire) or our April 7, 2021, proposed
rule. With no new information to consider, our conclusion regarding the
status of the Suwannee alligator snapping turtle remains the same.
(3) Comment: A commenter suggested we list the common snapping
turtle (C. serpentina) under the Act based on similarity of appearance
(see 16 U.S.C. 1533(e)) to help curb the threat of incidental captures
of Suwannee alligator snapping turtles by trappers that are targeting
common snapping turtles.
Our Response: Under section 4(e) of the Act (16 U.S.C. 1533(e)), a
species may be listed as endangered or threatened due to similarity of
appearance of a listed species if the species so closely resemble one
another that it is difficult to tell them apart and if this similarity
is a threat to the species that is warranted for listing. The
likelihood of incidental capture from legal common snapping turtle
harvest is anticipated to be low due to the disparity between the
preferred habitat types used by the common snapping turtle and the
Suwannee alligator snapping turtle. Common snapping turtle habitat
typically includes impoundments such as lakes, ponds, and oxbows. The
Suwannee alligator snapping turtle prefers more riverine systems. While
there may be some overlap between these habitat types and their ranges,
the Suwannee alligator snapping turtle can be distinguished from the
common snapping turtle based on certain physical characteristics. The
common snapping turtle shares some similar features to the Suwannee
alligator snapping turtle, but there are distinctive characteristics
that can aid in differentiation of the two species. The Suwannee
alligator snapping turtle's carapace has three keeled ridges and a
curved, hooked, beak-like projection at the mouth, while the common
snapping turtle lacks these features. Because of the physical
characteristics that are unique to each species that facilitate
identification, we have determined that listing the common snapping
turtle due to similarity of appearance is not necessary or appropriate.
(4) Comment: One commenter noted the Service's analysis of
redundancy and representation for the Suwannee alligator snapping
turtle in the SSA report was contrary to the agency's SSA framework and
commented that we did not describe representation in a meaningful way.
Our Response: Our analysis of the Suwannee alligator snapping
turtle's redundancy and representation adheres to the definitions
presented in the SSA framework. Representation is the ability of the
species to adapt to both near-term and long-term changes in its
physical and biological environment, and redundancy is the ability of
the species to withstand catastrophic events. At the time of our April
7, 2021, proposed rule, the best available scientific information
regarding the Suwannee alligator snapping turtle indicated there was no
genetic or environmental condition variation across the species' range.
We assessed representation, which measures a species' adaptive
potential in the face of natural or anthropogenic changes, as
inherently low for this species, because the best available information
at that time showed it lacked significant genetic variation within its
single population. Based on
[[Page 53510]]
the public comments and new literature related to assessing adaptive
capacity (Thurman et al. 2020, entire), in this final rule and our
revised SSA report, version 1.2 (Service 2022, entire), we updated our
discussion of representation by describing the Suwannee alligator
snapping turtle's adaptive capacity in terms of its genetic,
biological, and ecological traits necessary to understand the species'
plasticity to changing conditions over time. Adaptive capacity reflects
the amount of tolerance for change based on genotypic and phenotypic
attributes. Change can include impacts from climate change (e.g.,
higher air and water temperatures, saltwater intrusion, etc.) and
humans (e.g., water withdrawal, fishing gear, habitat alterations,
etc.). We assessed the Suwannee alligator snapping turtle to have low
to moderate adaptive capacity in the life-history and demography traits
and moderate to high adaptive capacity in the distribution, movement,
evolutionary potential, ecological role, and abiotic niche traits.
Further information on how we describe the species in terms of its
adaptive capacity with its ability to acclimate to environmental
stressors can be found in our SSA report, version 1.2 (Service 2022,
pp. 37-39).
For redundancy, in our proposed and this final rule, we assessed
current redundancy as limited, as the species is considered a single
population with no physical barriers to movement. While there is only a
single population, it is widely distributed across the historical
range. We assessed the chance of a catastrophic event affecting the
entire species as very low. However, given the Suwannee alligator
snapping turtle is currently assessed as a single population with an
estimated abundance of 2,000 turtles across the species' historical
range, we determined redundancy to be naturally limited, given the
species' distribution is limited to the Suwannee River basin.
4(d) Rule
(5) Comment: One commenter inquired why the Service did not apply
the blanket 4(d) rule to this species.
Our Response: Prior to August 27, 2019, the prohibitions for
endangered species under section 9 of the Act were generally extended
to threatened species (referred to as the ``blanket 4(d) rule'') unless
we adopted a species-specific 4(d) rule for a particular species. On
August 27, 2019, we published a final rule (84 FR 44753) removing the
blanket 4(d) rule for threatened species. That 2019 final rule was in
effect when we published our April 7, 2021, proposed rule for the
Suwannee alligator snapping turtle and is still in effect. On May 6,
2024, a rule became effective that re-instated the blanket 4(d) rule
(89 FR 23919). The updated regulations extend the majority of the
protections (all of the prohibitions that apply to endangered species
under section 9 with certain exceptions to those prohibitions) to
threatened species, unless we issue an alternative rule under section
4(d) of the Act for a particular species (i.e., a species-specific 4(d)
rule). For species with a species-specific 4(d) rule, that rule
contains all of the protective regulations for that species. We
exercised our authority under section 4(d) of the Act and developed a
proposed species-specific 4(d) rule to address the specific threats and
conservation needs of the Suwannee alligator snapping turtle. The 4(d)
rule is necessary and advisable to provide for the conservation of the
Suwannee alligator snapping turtle. For the species-specific 4(d) rule,
we determined that it is not necessary to apply all of the Act's
section 9 prohibitions to the Suwannee alligator snapping turtle; the
provisions of the species-specific 4(d) rule are described below under
Provisions of the 4(d) Rule and set forth below under Regulation
Promulgation.
(6) Comment: One commenter expressed concern that the Service's
description of the exceptions for construction, operation, and
maintenance in the 4(d) rule is too broad and vague to determine when
the exception applies.
Our Response: We agree that it is difficult to understand and
identify specific situations when the exception to incidental take
resulting for construction, operation, and maintenance activities would
apply. Accordingly, as stated above under Summary of Changes from the
Proposed Rule, we are not including an exception to the incidental take
prohibitions in the 4(d) rule for the Suwannee alligator snapping
turtle because it is too vague to meaningfully provide conservation
benefits to the species. In addition, many activities occurring near or
in a stream require permits or project review by Federal or State
agencies, and, if retained, this exception would have caused confusion
with respect to the requirements that must be met when undertaking
these activities.
(7) Comment: One commenter expressed concern about an exception for
silviculture and forestry BMPs, given the implementation of less
effective silviculture and forestry BMPs for riparian areas and
potential negative impacts to the species.
Our Response: State-approved BMPs for silviculture and forestry
maintain riparian buffers, resulting in reduced sedimentation into the
stream from upland sources, reduced water temperature, increased
dissolved oxygen, and more material for in-water woody debris. These
attributes promote aquatic diversity and are required for healthy
habitats.
Implementing BMPs that avoid or minimize the effects of habitat
alterations in areas that support Suwannee alligator snapping turtles
will provide additional measures for conserving the species by reducing
indirect effects to the species. We recognize that silvicultural
operations are widely implemented in accordance with State-approved
forestry BMPs (as reviewed by Cristan et al. 2018, entire), which
provide more stringent riparian protections, and the adherence to these
BMPs broadly protects water quality, particularly related to
sedimentation (as reviewed by Cristan et al. 2016, entire; Warrington
et al. 2017, entire; and Schilling et al. 2021, entire). For example,
Florida's State silviculture BMPs for designated outstanding Florida
waters, such as the Suwannee and Santa Fe Rivers, require a 300-foot
buffer on each side of the river. Forestry and silvicultural activities
that implement State-approved BMPs will have a de minimis impact on the
species, and we have determined that this exception to the incidental
take prohibitions in the 4(d) rule will be beneficial to the species.
If forestry and silvicultural activities do not implement or improperly
implement BMPs, then this exception will not apply.
(8) Comment: One commenter suggested that current regulatory
mechanisms are inadequate to address the threat of incidental bycatch
to the Suwannee alligator snapping turtle, and a 4(d) rule that excepts
take incidental to recreational fishing activities would only be
appropriate if the methods of fishing that incidentally capture turtles
were prohibited or significantly modified to prevent incidental
capture.
Our Response: In the proposed rule, we requested information
regarding ideas for the design of a turtle escape or exclusion device
and modified trot line techniques that would effectively eliminate or
significantly reduce bycatch of alligator snapping turtles from
recreational fishing; however, we did not receive any comments to
inform fishing gear modifications to reduce bycatch of Suwannee
alligator snapping turtles. Recreational fishing activities are
regulated by State natural resource and fish and game agencies, and
these agencies issue permits for these
[[Page 53511]]
activities in accordance with their regulations. We will coordinate
with State agencies to better understand the impacts of permitted
recreational fishing on Suwannee alligator snapping turtles. In
addition, we will work with the State to reduce the risk of bycatch,
which may include modifying fishing mechanisms based on the best
available science related to reducing fishing impacts through research
and development on innovative fishing technologies and methodologies.
Additionally, we will continue coordinating with State agencies on the
development of public awareness programs regarding identification and
conservation of the Suwannee alligator snapping turtle. Further, since
we did not receive information during the comment period for bycatch
reduction techniques, we do not include in the 4(d) rule an exception
to incidental take of the Suwannee alligator snapping turtle resulting
from bycatch from otherwise lawful recreational and commercial fishing
using techniques to reduce bycatch. Therefore, take of the species
resulting from bycatch is prohibited by the 4(d) rule.
(9) Comment: One commenter expressed concern about the 4(d) rule's
exception to the take prohibition for pesticide and herbicide use. The
commenter stated that the exception is arbitrary and not supported by
the best available scientific and commercial data. The commenter stated
that exposure to pesticides and herbicides is harmful to turtle species
and provided several citations to support the comment (such as, Bishop
et al. 1991, entire; Sparling et al. 2006, entire; Kittle et al. 2018,
entire))
Our Response: After review of the comments to the proposed rule and
revisiting the best available scientific and commercial information, we
are not including the pesticide and herbicide use exception from the
incidental take prohibitions in the final 4(d) rule. In the proposed
rule and this final rule, we describe the primary threats to the
Suwannee alligator snapping turtle as illegal harvest and collection,
nest predation, and hook ingestion and entanglement due to bycatch
associated with freshwater fishing. And although nest predation is a
primary threat to the species, the most common nest predators
identified are raccoons (Procyon lotor). Nonnative, invasive species,
such as feral pigs (Sus scrofa) and red imported fire ants (Solenopsis
invicta), occur across the species' range, but to date, nest predation
by these nonnative species has not been documented. In the preamble of
our proposed 4(d) rule, we proposed an exception to incidental take
prohibitions resulting from invasive species removal activities using
pesticides and herbicides as these types of activities could be
considered beneficial to the native ecosystem and are likely to improve
habitat conditions for the species. However, we do not have enough
information about the types or amounts of pesticides that may be
applied in areas where Suwannee alligator snapping turtle occurs to be
able assess the future impacts to the species.
The additional materials provided during the public comment period
do not indicate Suwannee alligator snapping turtle is impacted greatly
from pesticides used to reduce impacts from nonnative, invasive
species; however, the information provided does indicate impacts to
other turtle species from pesticide use (Bishop et al. 1991, entire;
Sparling et al. 2006, entire; Kittle et al. 2018, entire). As
documented in other turtle species from the literature provided by the
commenter, we assessed that there is the potential of indirect effects
from pesticides on the Suwannee alligator snapping turtle, and
therefore, including this exception to incidental take may not provide
for the conservation of the species.
Further, we note that the Environmental Protection Agency (EPA) has
not consulted on most pesticide registrations to date, so excepting
take solely based on users complying with labels is not appropriate in
this situation. Thus, we are not including the exception from the
prohibitions regarding incidental take resulting from herbicide/
pesticide use from this final rule.
(10) Comment: One commenter suggested modifying the 4(d) rule to
except captive breeding for turtles held in captivity prior to the
effective date of the listing to allow for appropriate captive-breeding
programs to contribute to the conservation of the species.
Our Response: We recognize the contribution of permitted captive
breeding to the conservation of species. However, there are currently
no captive-breeding efforts occurring for the Suwannee alligator
snapping turtle; therefore, there are no existing captive-breeding
programs that we could except prior to the effective date of this final
rule (see DATES, above). There are programs underway for M. temminckii
that include captive rearing, head-start programs, and reintroductions
that are successful. Similar programs may be implemented in the future
to conserve the Suwannee alligator snapping turtle. In our proposed
4(d) rule, we included a provision allowing incidental take associated
with Federal and State captive-breeding programs to support
conservation efforts for wild populations. However, we determined this
provision is duplicative of an exception under 50 CFR 17.31(b), which
we also included in the proposed 4(d) rule and retain in this final
4(d) rule. Therefore, this final 4(d) rule does not include a separate
captive-breeding exception from the incidental take prohibitions.
Critical Habitat
(11) Comment: A commenter claimed that the Service did not provide
sufficient support for the not-prudent finding for critical habitat
designation regarding the threat of illegal collection of the Suwannee
alligator snapping turtle. The commenter also indicates the location
data and maps are already available to the public in published reports.
Our Response: We recognize that designation of critical habitat can
provide benefits to listed species; however, for the Suwannee alligator
snapping turtle, increased threats caused by the designation outweigh
the benefits (for further discussion, see 86 FR 18014, April 7, 2021,
at p. 18032). We do not dispute the claim that publicly available
reports identify specific location data for the species, including
locations of where the species occurs from trapping efforts. We
acknowledge that general location information is provided within the
proposed rule and this final rule, and some specific location
information can be found through other sources. However, because the
critical habitat designation process includes identifying the physical
or biological features for the species and specific areas occupied by
the species, the designation of critical habitat would describe and
disclose areas of higher quality habitat that supports more turtles,
which may allow collectors to better focus their efforts in these
areas, thereby exacerbating the threat of collection or other harm from
humans.
I. Final Listing Determination
Background
Please refer to the April 7, 2021, proposed rule (86 FR 18014) and
the SSA report, version 1.2 (Service 2022, pp. 4-14) for a full summary
of species' information. Both are available on our ECOS website for the
species at https://ecos.fws.gov/ecp/species/10891 and at https://www.regulations.gov under Docket No. FWS-R4-ES-2021-0007.
A thorough review of the taxonomy, distribution, life history, and
ecology of
[[Page 53512]]
the Suwannee alligator snapping turtle (Macrochelys suwanniensis) is
presented in the SSA report version 1.2 (Service 2022, pp. 13-22);
however, much of this information is based on the Macrochelys genus as
a whole and describes the Suwannee alligator snapping turtle using the
best available information.
Turtles in the genus Macrochelys are the largest species of
freshwater turtle in North America, are highly aquatic, and are
somewhat secretive. The genus includes two distinct species, M.
temminckii and M. suwanniensis. Macrochelys turtles are characterized
as having a large head, long tail, and an upper jaw with a strongly
hooked beak. They have three raised keels with posterior elevations on
the scutes of the carapace (upper shell), which is dark brown and often
has algal growth that adds to their camouflage. Their eyes are
positioned on the side of the head and are surrounded by small, fleshy,
pointed projections that are unique to the genus.
Suwannee alligator snapping turtles are primarily freshwater
turtles endemic to the Suwannee River basin and found more abundantly
in the middle reaches of the Suwannee River where freshwater springs
contribute to an increase in productivity of the aquatic system (Enge
et al. 2014, p. 36). These turtles are typically bottom-dwelling, but
surface periodically to breathe (Thomas 2014, p. 60). While the species
is typically found in fresh water, it can tolerate some salinity and
brackish waters, as barnacles have been found on the carapace of some
turtles. The species is found in a variety of habitats across its
range, but all life stages rely on submerged material (i.e., deadhead
logs and vegetation) as important structure for resting, foraging, and
cover from predators (Enge et al. 2014, p. 39).
The Suwannee River basin encompasses parts of southern Georgia and
northern Florida. Main water bodies that currently or historically
supported the Suwannee alligator snapping turtle include the Suwannee
River, Santa Fe River, New River, Alapaha River, Little River, and
Withlacoochee River. Individuals occupy main river channels and
tributaries where habitat is present.
Throughout this document, we provide descriptions of the Suwannee
alligator snapping turtle where the information is available specific
to the species. We describe the Suwannee alligator snapping turtle as
Macrochelys suwanniensis or Suwannee alligator snapping turtle. We
reference Macrochelys when describing the genus and Macrochelys
temminckii (abbreviated as M. temminckii) when referring to the second
species of the genus, alligator snapping turtle. Since the taxonomic
distinction of the two Macrochelys spp. is relatively recent, we may
refer to the genus, or alligator snapping turtles in general, to
describe life-history traits.
The general life stages of Macrochelys spp. can be described as
egg, hatchling (first year), juvenile (second year until age of sexual
maturity), and adult (age of sexual maturity through death). Each life
stage has specific requirements in order to contribute to the
productivity of the next life stage. They excavate nests in sandy soils
or other dry substrate near freshwater sources that are within 8 to 656
feet (ft) (2.5 to 200 meters (m)) from the shore. The incubation period
for Suwannee alligator snapping turtle is between 105 to 110 days
(Ernst and Lovich 2009, p. 145).
Males achieve sexual maturity in 11-21 years and females in 13-21
years (Ernst and Lovich 2009, p. 144; Reed et al. 2002, p. 4). The age
of sexual maturity can be influenced by the size of the turtle, as size
increases are greater when food resources and other environmental
conditions are more favorable. Adult Suwannee alligator snapping
turtles require streams and rivers with submerged logs and undercut
banks, clean water, and ample prey.
Female alligator snapping turtles may produce a single clutch once
a year or every other year at most even if the conditions are good
(Reed et al. 2002, p. 4). Clutch size may vary across the species'
range to between 9 and 61 eggs, with a mean clutch size of 27 eggs
(Ernst and Lovich 2009, p. 145). Most nesting occurs from May to July
(Reed et al. 2002, p. 4).
Suwannee alligator snapping turtles are long-lived species;
provided suitable conditions, adults can reach carapace lengths of up
to 29 inches and 249 pounds for males, while females can reach lengths
of 22 inches and 62 pounds. The oldest documented Macrochelys turtle in
captivity survived to at least 80 years of age, but in the wild, the
species may live longer (Ernst and Lovich 2009, p. 147). The generation
time for the species is around 31 years (range = 28.6-34.0 years, 95
percent confidence interval, Folt et al. 2016, p. 27).
Regulatory and Analytical Framework
Regulatory Framework
Section 4 of the Act (16 U.S.C. 1533) and the implementing
regulations in title 50 of the Code of Federal Regulations set forth
the procedures for determining whether a species is an endangered
species or a threatened species, issuing protective regulations for
threatened species, and designating critical habitat for endangered and
threatened species. On April 5, 2024, jointly with the National Marine
Fisheries Service, the Service issued a final rule that revised the
regulations in 50 CFR part 424 regarding how we add, remove, and
reclassify endangered and threatened species and what criteria we apply
when designating listed species' critical habitat (89 FR 24300). On the
same day, the Service published a final rule revising our protections
for endangered species and threatened species at 50 CFR part 17 (89 FR
23919). These final rules are now in effect and are incorporated into
the current regulations. Our analysis for this final decision applied
our current regulations. Given that we proposed listing for this
species under our prior regulations (revised in 2019), we have also
undertaken an analysis of whether our decision would be different if we
had continued to apply the 2019 regulations; we concluded that the
decision would be the same. The analyses under both the regulations
currently in effect as of May 6, 2024, and the 2019 regulations are
available on https://www.regulations.gov.
The Act defines an ``endangered species'' as a species that is in
danger of extinction throughout all or a significant portion of its
range, and a ``threatened species'' as a species that is likely to
become an endangered species within the foreseeable future throughout
all or a significant portion of its range. The Act requires that we
determine whether any species is an endangered species or a threatened
species because of any of the following factors:
(A) The present or threatened destruction, modification, or
curtailment of its habitat or range;
(B) Overutilization for commercial, recreational, scientific, or
educational purposes;
(C) Disease or predation;
(D) The inadequacy of existing regulatory mechanisms; or
(E) Other natural or manmade factors affecting its continued
existence.
These factors represent broad categories of natural or human-caused
actions or conditions that could have an effect on a species' continued
existence. In evaluating these actions and conditions, we look for
those that may have a negative effect on individuals of the species, as
well as other actions or conditions that may ameliorate any negative
effects or may have positive effects.
We use the term ``threat'' to refer in general to actions or
conditions that are known to or are reasonably likely to
[[Page 53513]]
negatively affect individuals of a species. The term ``threat''
includes actions or conditions that have a direct impact on individuals
(direct impacts), as well as those that affect individuals through
alteration of their habitat or required resources (stressors). The term
``threat'' may encompass--either together or separately--the source of
the action or condition or the action or condition itself.
However, the mere identification of any threat(s) does not
necessarily mean that the species meets the statutory definition of an
``endangered species'' or a ``threatened species.'' In determining
whether a species meets either definition, we must evaluate all
identified threats by considering the species' expected response and
the effects of the threats--in light of those actions and conditions
that will ameliorate the threats--on an individual, population, and
species level. We evaluate each threat and its expected effects on the
species, then analyze the cumulative effect of all of the threats on
the species as a whole. We also consider the cumulative effect of the
threats in light of those actions and conditions that will have
positive effects on the species, such as any existing regulatory
mechanisms or conservation efforts. The Secretary determines whether
the species meets the definition of an ``endangered species'' or a
``threatened species'' only after conducting this cumulative analysis
and describing the expected effect on the species now and in the
foreseeable future.
The Act does not define the term ``foreseeable future,'' which
appears in the statutory definition of ``threatened species.'' Our
implementing regulations at 50 CFR 424.11(d) set forth a framework for
evaluating the foreseeable future on a case-by-case basis which is
further described in the 2009 Memorandum Opinion on the foreseeable
future from the Department of the Interior, Office of the Solicitor (M-
37021, January 16, 2009; ``M- Opinion,'' available online at https://www.doi.gov/sites/doi.opengov.ibmcloud.com/files/uploads/M-37021.pdf).
The foreseeable future extends as far into the future as the U.S. Fish
and Wildlife Service and National Marine Fisheries Service (hereafter,
the Services) can make reasonably reliable predictions about the
threats to the species and the species' responses to those threats. We
need not identify the foreseeable future in terms of a specific period
of time. We will describe the foreseeable future on a case-by-case
basis, using the best available data and taking into account
considerations such as the species' life-history characteristics,
threat-projection timeframes, and environmental variability. In other
words, the foreseeable future is the period of time over which we can
make reasonably reliable predictions. ``Reliable'' does not mean
``certain''; it means sufficient to provide a reasonable degree of
confidence in the prediction, in light of the conservation purposes of
the Act.
Analytical Framework
The SSA report documents the results of our comprehensive
biological review of the best scientific and commercial data regarding
the status of the species, including an assessment of the potential
threats to the species. The SSA report does not represent our decision
on whether the species should be listed as an endangered or threatened
species under the Act. However, it does provide the scientific basis
that informs our regulatory decisions, which involve the further
application of standards within the Act and its implementing
regulations and policies.
To assess Suwannee alligator snapping turtle's viability, we used
the three conservation biology principles of resiliency, redundancy,
and representation (Shaffer and Stein 2000, pp. 306-310). Briefly,
resiliency is the ability of the species to withstand environmental and
demographic stochasticity (for example, wet or dry, warm or cold
years); redundancy is the ability of the species to withstand
catastrophic events (for example, droughts, large pollution events);
and representation is the ability of the species to adapt to both near-
term and long-term changes in its physical and biological environment
(for example, climate conditions, pathogens). In general, species
viability will increase with increases in resiliency, redundancy, and
representation (Smith et al. 2018, p. 306). Using these principles, we
identified the species' ecological requirements for survival and
reproduction at the individual, population, and species levels, and
described the beneficial and risk factors influencing the species'
viability.
The SSA process can be categorized into three sequential stages.
During the first stage, we evaluated the individual species' life-
history needs. The next stage involved an assessment of the historical
and current condition of the species' demographics and habitat
characteristics, including an explanation of how the species arrived at
its current condition. The final stage of the SSA involved making
predictions about the species' responses to positive and negative
environmental and anthropogenic influences. Throughout all of these
stages, we used the best available information to characterize
viability as the ability of a species to sustain populations in the
wild over time. We use this information to inform our regulatory
decision. The following is a summary of the key results and conclusions
from the SSA report; the full SSA report can be found at Docket FWS-R4-
ES-2021-0007 on https://www.regulations.gov.
Summary of Biological Status and Threats
In this discussion, we review the biological condition of the
species and its resources, and the threats that influence the species'
current and future condition, in order to assess the species' overall
viability and the risks to that viability.
The Suwannee alligator snapping turtle is found in the Suwannee
River basin in Georgia and Florida. The species is mostly aquatic and
uses a variety of habitat types including deeper water of large rivers
and their major tributaries; however, they are also found in a wide
variety of habitats, including small streams, springs, bayous, canals,
swamps, lakes, reservoirs, and ponds. This large turtle species is an
opportunistic feeder and consumes a variety of foods. Fish comprise a
significant portion of its diet; however, crayfish, mollusks, smaller
turtles, insects, snakes, birds, and vegetation (including acorns) have
also been reported (Elsey 2006, pp. 448-489; Elbers and Moll 2011,
entire). Additional information regarding the species' needs is
provided in the SSA report (Service 2022, pp. 4-14) and the proposed
listing rule (86 FR 18014; April 7, 2021).
Threats
We provide information regarding past, present, and future
influences, including both positive and negative influences, on the
Suwannee alligator snapping turtle's current and future viability,
including illegal harvest (Factor B), bycatch (Factor E), habitat loss
and degradation (Factor A), nest predation (Factor C), climate change
(Factor E), and conservation measures. The existing regulatory
mechanisms (Factor D) have not been adequate to arrest the decline of
the species. Additional threats such as historical commercial and
recreational harvest targeting the species, disease, parasitic insects,
boating, and contaminants are described in the SSA report (Service
2022, pp. 15-22); these additional threats may negatively affect
individuals of the species or have historically
[[Page 53514]]
affected the species, particularly when compounded with other ongoing
stressors or threats, but they do not impact the species' overall
current or future viability.
Harvest (Commercial and Poaching)
Commercial and recreational turtle harvesting practices in the last
century resulted in a decline of the Suwannee alligator snapping turtle
across its range (Enge et al. 2014, p. 4). Commercial harvest of both
species of alligator snapping turtles reached its peak in the late
1960s and 1970s, when the meat was used for commercial turtle soup
products and sold in large quantities for public consumption. In
addition, many restaurants served turtle soup and purchased large
quantities of alligator snapping turtles from trappers in the
southeastern States (Reed et al. 2002, p. 5). In the 1970s, the demand
for turtle meat was so high that as much as three to four tons of
alligator snapping turtles (M. temminckii) were harvested from the
Flint River in Georgia per day (Pritchard 1989, p. 76). The Florida
Game and Fresh Water Fish Commission (now the Florida Fish and Wildlife
Conservation Commission (FWC)) reported significant numbers of turtles
being taken from the Apalachicola and Ochlocknee Rivers to presumably
be sent to restaurants in New Orleans and other destinations (Pritchard
1989, pp. 74-75). While such large-scale removal of Macrochelys turtles
occurred across the range of the genus, the population demographics of
Suwannee alligator snapping turtles in Florida indicate there was
likely less commercial harvesting activities in the Suwannee River
drainage than elsewhere (Enge et al. 2017, p. 6; Enge et al. 2014,
entire; Johnston et al. 2015, entire).
Florida prohibited the commercial harvest of all Macrochelys spp.
in 1972, and recreational or personal harvest in 2009; Georgia
prohibited all harvest in 1992 (Service 2022, pp. 27-29). Despite the
prohibitions on commercial and recreational harvest for the species,
the historical removal of large turtles continues to affect the species
due to their low fecundity, low juvenile survival, long lifespan, and
delayed maturity. Commercial harvest is not currently a threat to the
Suwannee alligator snapping turtle, but the effect of historical,
large-scale removal of large turtles is ongoing.
Although both Florida and Georgia have prohibited recreational
harvest, there is an international and domestic demand for turtles for
consumption and for herpetofauna enthusiasts who collect turtle species
for pets (Stanford et al. 2020, entire). The Suwannee alligator
snapping turtle is no exception; farmed, hatchling alligator snapping
turtles may be sold for up to 400 U.S. dollars per turtle (Lejeune et
al. 2020, p. 8; MorphMarket 2024, unpaginated). Illegal harvest, or
poaching, of Suwannee alligator snapping turtles may occur anywhere
within the species' range for both the pet trade and turtle meat trade.
The best available information regarding potential pressure from
poaching comes from documented reports by law enforcement agencies and
court cases involving the congeneric (species within the same genus)
alligator snapping turtle. In 2017, three men were convicted of
violating the Lacey Act (16 U.S.C. 3371-3378; 18 U.S.C. 42) because
they collected 60 large alligator snapping turtles (M. temminckii) in a
single year in Texas and transported them across State lines (see
United States v. Travis Leger et al., No. 1:17-CR-00040 (E.D. Tex.)).
We expect that illegal harvest is affecting Suwannee alligator snapping
turtles, given it has been documented on many occasions for the
heterospecific alligator snapping turtle. Illegal harvest is an ongoing
threat to the Suwannee alligator snapping turtle because removing adult
female turtles from the population lowers the viability of the species
by reducing reproductive potential; in addition, the species is long-
lived, slow to mature, and juvenile survival is very low, making it
more difficult for the historically over-harvested population to
recover.
Aside from the local and domestic use of turtles, the global demand
for pet turtles and turtle meat continues to increase. Many species of
turtles are collected from the wild as well as bred in captivity and
are sold domestically and exported internationally. Macrochelys spp.
are regularly exported out of the United States, typically as
hatchlings or juveniles, to initiate brood stock for overseas turtle
farms and for turtle collectors. According to the Service's Law
Enforcement Management Information System (LEMIS), which provides
reports about the legal international wildlife trade, most shipments of
live alligator snapping turtles exported from 2005 to 2018 consisted of
small turtles destined mostly for Hong Kong and China (Service 2018,
entire). Prior to 2006, up to 23,780 M. temminckii per year were
exported from the United States (70 FR 74700; December 16, 2005). Since
the time of the proposed listing, the species has been uplisted to
CITES Appendix II that may provide additional protections to the
species. See the section below for additional information, Conservation
Efforts and Regulatory Mechanisms.
Impacts of Harvest
Because of the Suwannee alligator snapping turtle's delayed
maturity, long generation times, and relatively low reproductive
output, the species cannot sustain collection from the wild, especially
of adult females, over any length of time (Reed et al. 2002, pp. 8-12).
Adult turtles do not reach sexual maturity until 11 to 21 years of age.
A mature female typically produces only one clutch per year consisting
of 8-52 eggs (Ernst and Barbour 1989, p. 133). These turtles are
characterized by low survivorship in early life stages, but surviving
individuals may live many decades once they reach maturity. The life-
history traits of the species (low fecundity, late age of maturity, and
low survival of nests and juveniles) contribute to the population's
slow response rebound after historical over-exploitation. Therefore,
population growth rates are extremely sensitive to the harvest of adult
females. Adult female survivorship of less than 98 percent per year is
considered unsustainable, and a further reduction of this adult
survivorship will generally result in significant local population
declines (Reed et al. 2002, p. 9), although dynamics likely vary across
the species' range. These data underscore how influential adult female
mortality is on the ability of the species to maintain viability.
Although regulatory harvest restrictions have decreased the number
of Suwannee alligator snapping turtles harvested, populations have not
necessarily increased in response. This lag in population response is
likely due to the demography of the species--specifically delayed
maturity, long generation times, and relatively low reproductive
output. The Suwannee alligator snapping turtle population remains low
despite commercial and recreational harvest prohibitions (Florida Fish
and Wildlife Conservation Commission 2017, p. 6). Through expert
elicitation, the magnitude of the threat of illegal harvest or poaching
across the basin ranges from 20-55 percent of the species' range may be
affected (Service 2022, p. 28).
Bycatch
Suwannee alligator snapping turtles can be killed or harmed
incidentally during fishing and other recreational activities. Some of
these threats include fishhook ingestion; drowning when hooked on
trotlines (a fishing line strung across a stream with multiple hooks
set at intervals), limb lines, bush
[[Page 53515]]
hooks (single hooks hung from branches), or jug lines (line with a hook
affixed to a floating jug); and injuries or drowning when entangled in
various types of fishing line. The magnitude of the threat due to
incidental hooking (i.e., recreational trot and limb lines, fishing
tackle, etc.) as provided though expert elicitation describes the
impact to the species as affecting between 30-75 percent of the
species' range (Service 2022, p. 28).
Hoop nets are also used to capture catfish and baitfish and are
made up of a series of hoops with netting and funnels where fish enter
but are unable to escape through the narrow entry point. The nets are
left submerged and may entrap small Suwannee alligator snapping turtles
that enter the traps and are unable to escape. Actively used or
discarded fishing line and hooks pose harm to Suwannee alligator
snapping turtles. They can ingest baited fishhooks and attached fishing
line and depending on where ingested hooks and line lodge in the
digestive tract, they can cause harm or death (Enge et al. 2014, pp.
40-41). For example, hooks and line can cause gastrointestinal tract
blockages, and the hooks can puncture the digestive organs, leading to
mortality (Enge et al. 2014, pp. 40-41). Fishhooks have been found in
the gastrointestinal tracts of radiographed Suwannee alligator snapping
turtles (Enge et al. 2014, entire; Thomas 2014, pp. 42-43).
Trotlines also negatively affect Suwannee alligator snapping
turtles. Trotlines are a series of submerged lines with hooks off a
longer line. Trotline fishing involves leaving the lines unattended for
extended periods, before returning to check them. Limblines and bush
hooks are similar to trot lines in that they are typically set and left
unattended; however, they only use a single hook. The turtles can
become entangled in the lines and drown, as well as ingest trotline
hooks and lines, also causing drowning or internal injuries. Bycatch
from trotlines that resulted in mortality of Macrochelys turtles has
been well documented. Dead turtles have been found on lines that had
seemingly been abandoned (Moore et al. 2013, p. 145). The lines and
hooks may also become dislodged from their place of attachment when
left unattended, becoming aquatic debris that remains in the waterway
for extended periods of time and may continue to be an entanglement
hazard for many species, including Suwannee alligator snapping turtles.
Habitat Alteration and Degradation
The Suwannee alligator snapping turtle's aquatic and nesting
habitats have been altered by anthropogenic disturbances. Changes in
the riparian or nearshore areas affect the amount of suitable soils for
nesting sites because the species constructs nests on land near the
water. Riparian cover is important as it moderates in-stream water
temperatures and dissolved oxygen levels. In addition to affecting the
distribution and abundance of alligator snapping turtle prey species,
these microhabitat conditions affect the snapping turtles directly.
Moderate temperatures and sufficient dissolved oxygen levels allow the
turtles to remain stationary on the stream bottom for longer periods,
increasing the ambush foraging opportunities. Changes in the riparian
structure may affect the microclimate and conditions of the associated
water body, directly affecting the foraging success of the turtles.
Activities and processes that can alter habitat include dredging,
deadhead logging (removal of submerged or partially submerged snags,
woody debris, and other large vegetation for wood salvage), removal of
riparian cover, channelization, stream bank erosion, siltation, and
land use adjacent to rivers (e.g., clearing land for agriculture).
These activities negatively influence habitat suitability for Suwannee
alligator snapping turtles. Erosion can change the stream bank
structure, affecting the substrate that may be suitable for nesting or
accessing nesting sites. Siltation affects water quality and may reduce
the health and availability of prey species. Channelization destroys
the natural benthic habitat and also affects the water depth and normal
flow. Submerged obstacles may be removed during the channelization,
which affects the microhabitat dynamics within the waterway and removes
important structures for alligator snapping turtles to use for resting,
foraging, and cover from predators. While channelization within the
species' range does not regularly occur, it is not prohibited. Deadhead
logs and fallen riparian woody debris, where present, provide refugia
during low-water periods and resting areas for all life stages and
support important feeding areas for hatchlings and juveniles (Enge et
al. 2014, p. 40; Ewert et al. 2006, p. 62).
Suwannee alligator snapping turtle habitat is also influenced by
water availability and quantity, as well as water quality, across the
species' range. Ground water withdrawals in the Florida portion of the
species' range are managed by the Suwannee River Water Management
District (SRWMD); withdrawals increased by 64 percent between 1975 and
2000, mostly for irrigation. Most withdrawals in the basin occur in
agricultural areas along the Suwannee River during the spring (March
through May) (Thom et al. 2015, p. 2). Water withdrawals may reduce
flow in some streams, effectively isolating some turtles from the rest
of the population or making immature turtles more vulnerable to
predators. Additionally, reduced water levels may impact prey abundance
and distribution through restricting habitat connectivity, reducing
dissolved oxygen levels, and increasing water temperatures.
Water quality may also be a factor for Suwannee alligator snapping
turtles as contaminants enter the aquatic systems through runoff. The
Lower Suwannee River's middle and lower basins are directly impacted by
nutrients, including nitrates. Agricultural practices are the main
source of nitrates, which specifically come from fertilizers and in
some cases from manure and other waste products. They introduce
nitrates to the river and groundwater (i.e., springs) through surface
runoff and groundwater seepage. Groundwater seepage transports nitrates
to the aquifer, which then reemerge through springs and other
groundwater discharge, especially during low-flow periods (Pittman et
al. 1997, entire; Katz et al. 1999, entire; Thom et al. 2015, p. 2).
The direct effects of water quality and water quantity on the
Suwannee alligator snapping turtle have not been quantified; however,
as the human population that relies on water systems in the species'
range continues to increase, the indirect effects across the entire
range, coupled with other stressors, is likely to further reduce the
species' viability. Underscoring the potential severity of this threat,
Florida's human population is anticipated to grow from nearly 21.5
million in 2019 to more than 24.0 million by 2030 (Rayer and Wang 2020,
p. 9). The public water supply demand will increase with increased
human population growth. All counties within the species' range in
Florida (Alachua, Bradford, Columbia, Dixie, Gilchrist, Hamilton,
Lafayette, Levy, Madison, Suwannee, and Union Counties) are part of the
SRWMD supply area and are projected to increase the public water supply
demand by an average of 11.29 percent in millions of gallons of water
per day from 2010 to 2035 (SRWMD 2015, p. 42). In addition, the human
population in these counties will experience an average of 17.25
percent population growth from the year 2010 to 2035 (SRWMD 2015, p.
43). As the human population increases, other threats to the species
and its habitat are
[[Page 53516]]
likely to increase. For example, recreational use of the Suwannee River
will more than likely continue to rise, which will increase human
encounters with Suwannee alligator snapping turtles through incidental
bycatch. Also, more development may result in an increase in
contaminated runoff and declines in water quality.
Nest Predation
Nest predation rates for Macrochelys spp. are high. Raccoons
(Procyon lotor) are common nest predators, but nine-banded armadillos
(Dasypus novemcinctus), Virginia opossums (Didelphis virginiana),
bobcats (Lynx rufus), and river otters (Lontra canadensis) may also
depredate nests (Ernst and Lovich 2009, p. 149; Ewert et al. 2006, p.
67; Holcomb and Carr 2013, p. 482). Additional nonnative species found
within the species' range that may depredate nests include feral pigs
(Sus scrofa) and invasive red imported fire ants (Solenopsis invicta)
(Pritchard 1989, p. 69). Although not documented in Suwannee alligator
snapping turtle nests, fire ants are prevalent across the species'
range, and predation by fire ants was the suspected culprit in the
failure of alligator snapping turtle (M. temminckii) nests in Louisiana
(Holcomb 2010, p. 51). Beyond nest failure, some hatchlings endured
wounds inflicted by fire ants that led to the loss of a limb or tail,
which reduced their mobility and their chance of survival (Holcomb
2010, p. 72). The recovery of the species from historical overharvest
depends on successful reproduction and survival of young. The currently
low population size does not allow for absorbing the impact of elevated
nest predation. The degree of added threat from the newer, introduced
nest predators is unknown, but we can conclude that the overall threat
from nest predation is greater than it was in the past because of
introduced predators such as feral hogs, and fire ants. The magnitude
of nest predation by native and exotic species affected between 5-10
percent of the spatial extent of the species' range, as provided
through expert elicitation (Service 2022, p. 28). Coupled with other
threats, nest predation will continue to negatively affect the species'
overall viability.
Climate Change
Climate change may also affect the Suwannee alligator snapping
turtle to varying degrees, but the extent of impact is influenced by
certain geographical factors, including proximity to the coast and
latitudinal thermogradients. Climate change may affect the Suwannee
alligator snapping turtle in several ways. First, the effects of
decreased precipitation due to climate change will cause an increase in
water withdrawal for human use (i.e., potable water and agriculture
irrigation). Additionally, reduced precipitation may directly and
indirectly impact habitat, food, and water availability throughout the
Suwannee River basin. Available water will be reduced as evaporation
increases with continued warming temperatures. Furthermore, increased
temperatures may have physiological impacts on sex ratios because these
turtles have temperature-dependent sex determination, and higher
temperatures may skew the sex ratio.
In the southeastern United States, temperatures are predicted to
warm by 4 to 8 degrees Fahrenheit ([deg]F) (2.2 to 4.4 degrees Celsius
([deg]C)) by 2100 (Carter et al. 2014, p. 399). Temperature determines
the sex of the Macrochelys developing embryos; certain nest
temperatures result in primarily male hatchlings with females produced
at temperatures of the two extremes of the intermediate male-producing
temperatures. Females are produced when the nest temperatures are
either cooler or warmer than the temperature threshold for male
development. In order to develop mixed ratios of both sexes,
fluctuating temperatures near the intermediate and extremes are ideal.
In addition to temperature effects on sex ratio, temperature has been
associated with nest viability, with highest viability in nests with
intermediate sex ratios (produced at the male-producing intermediate
temperature range with fluctuations of warmer or cooler temperatures
for female-producing temperatures during the incubation period) and
lowest in nests with female-biased sex ratios (Ewert and Jackson 1994,
pp. 28-29). Thus, warming temperatures might lead to Suwannee alligator
snapping turtle nests with strongly female-biased sex ratios. These
skewed sex ratios may result in declining viability as mating behaviors
are altered and other issues with unbalanced populations arise.
Collectively, these impacts from reduced precipitation and
increased temperature would reduce the quality or availability of
suitable habitat for the Suwannee alligator snapping turtle (Thom et
al. 2015, p. 126). Climate change impacts on the Suwannee alligator
snapping turtle will likely act in concert with, and exacerbate, the
impacts of other threats and stressors.
Other Stressors
Other stressors that may affect Suwannee alligator snapping turtles
include disease, nest parasites, contaminants from urban and
agricultural runoff, and historical recreational harvest, but none of
these stressors are having species-level impacts on the Suwannee
alligator snapping turtle. These stressors may act on individuals or
have highly localized impacts. While each is relatively uncommon, these
stressors may exacerbate the effects of other ongoing threats.
Additional information on these stressors acting on the species is
available in the species' SSA report under ``Factors Influencing
Viability'' (Service 2022, pp. 23-29). This information includes
historical and current threats that have caused and are causing a
decline in the species' viability. The primary threats currently acting
on the species include illegal harvest, nest predation, and hook
ingestion and entanglement due to bycatch associated with freshwater
fishing. These primary threats are not only affecting the species now
but are expected to continue impacting the species and were included in
the species' future condition projections in the SSA report (Service
2022, pp. 41-56).
Conservation Efforts and Regulatory Mechanisms
Clean Water Act
Section 401 of the Federal Clean Water Act (CWA; 33 U.S.C. 1251 et
seq.) requires that an applicant for a Federal license or permit
provide a certification that any discharges from the facility will not
degrade water quality or violate water-quality standards, including
State-established water quality standard requirements. Section 404 of
the CWA establishes programs to regulate the discharge of dredged and
fill material into waters of the United States.
Nationwide, regional general, or individual permits are issued by
the Florida Department of Environmental Protection or U.S. Army Corps
of Engineers to fill wetlands; to install, replace, or remove culverts;
to install, repair, replace, or remove bridges; or to realign streams
or water features. These permit types are summarized below.
Nationwide permits are for ``minor'' impacts to streams
and wetlands, and do not require an intense review process. The impacts
allowed under nationwide permits usually include projects affecting
stream reaches less than 150 ft (45.72 m) in length, and wetland fill
projects up to 0.50 acres (0.2 hectares). Mitigation is usually
provided for the same type of wetland or stream impacted and is usually
at a 2:1 ratio to offset losses.
[[Page 53517]]
Regional general permits are for various specific types of
impacts that are common to a particular region; these permits will vary
based on location in a certain region or State.
Individual permits are for the larger, higher impact, and
more complex projects. These require a complex permit process with
multi-agency input and involvement. Impacts in these types of permits
are reviewed individually, and the compensatory mitigation chosen may
vary depending on the project and types of impacts.
The CWA regulations, set forth in title 40 of the Code of Federal
Regulations (CFR) for the Environmental Protection Agency and in title
33 of the CFR for the U.S. Army Corps of Engineers, ensure proper
mitigation measures are applied to minimize the impact of activities
occurring in streams and wetlands where the species occurs. These
regulations contribute to the conservation of the species by minimizing
or mitigating the effects of certain activities on Suwannee alligator
snapping turtles and their habitat.
Convention on International Trade in Endangered Species of Wild Fauna
and Flora (CITES)
Suwannee alligator snapping turtle is included in the CITES
Appendices under Macrochelys temminckii, based on the CITES standard
nomenclature reference for turtles (Fritz & Hava[scaron] 2007, p. 172),
which recognizes M. temminckii as the only taxon in the genus
Macrochelys. This species was originally included in CITES Appendix III
in 2006, when the genus was recognized as a single species, described
as Macroclemys and synonymous with Macrochelys (70 FR 74700; December
16, 2005). At the 19th Conference of the Parties (November 2022),
Macrochelys temminckii was transferred from Appendix III of CITES to
Appendix II (CITES 2023, pp. 45-46). Because CITES only recognizes a
single species of Macrochelys (M. temminckii), both taxa, the alligator
snapping turtle and the Suwannee alligator snapping turtle, are
protected under CITES Appendix II regulations.
CITES requires permits for exports of Appendix II species, which
are only issued when: (1) the Scientific Authority has advised that the
export will not be detrimental to the survival of the species; (2) the
Management Authority is satisfied that the specimen(s) were legally
acquired; and (3) the Management Authority is satisfied that any living
specimens will be prepared and shipped so as to minimize the risk of
injury, damage to health, or cruel treatment. Export numbers are also
monitored by U.S. CITES Authorities and reported to CITES annually.
Whenever a Scientific Authority determines that the export of specimens
of any such species should be limited in order to maintain that species
throughout its range at a level consistent with its role in the
ecosystems in which it occurs and well above the level at which that
species might become eligible for inclusion in Appendix I, the
Scientific Authority shall advise the appropriate Management Authority
of suitable measures to be taken to limit the grant of export permits
for specimens of that species.These requirements help regulate and
document legal, international trade; they further ensure that specimens
entering international trade are acquired legally, and that the trade
of the species is biologically sustainable for, and will not be
detrimental to the survival of, the species. Thus, Appendix II
regulations complement and lend additional support to State wildlife
agencies in their efforts to regulate and manage these species, improve
data gathering to increase knowledge of trade in the species, and
strengthen State and Federal wildlife enforcement activities to prevent
poaching and illegal trade.
When this taxon was included in CITES Appendix III, reporting of
annual exports was also required. While CITES reporting indicates the
number of turtles exported with other relevant data, in the past, the
information required for the export reports has not always accurately
identified the source stock of the exported turtle(s). Most alligator
snapping turtles that were exported between 2005 and 2018 were
identified as ``wild'' individuals; however, many were likely from
farmed parental stock (Service 2018, entire). The discrepancy in
reporting the actual source of the internationally exported turtles has
not allowed us to easily evaluate the impact of export on Suwannee
alligator snapping turtles. Inclusion in Appendix II, unlike Appendix
III, requires an evaluation that the export will not be detrimental to
the survival of the species, which will help better assess the impact
of export.
National Wildlife Refuges
Approximately 5 percent of the Suwannee alligator snapping turtle's
range includes areas within two National Wildlife Refuges (NWR),
Okefenokee in Georgia and Lower Suwannee in Florida. These NWRs are
managed by the Service to conserve native wildlife species and their
habitats and are protected from future development. Both NWRs have
comprehensive conservation plans (CCP) that ensure each NWR is managed
to fulfill the purpose(s) for which it was established.
Okefenokee NWR is at the northernmost proximity of the species'
range and is a freshwater wetland. There are only a few anecdotal
reports of the species occurring within Okefenokee NWR. There have been
no systematic surveys conducted within the swamp, so the extent of use
by the species of that area has not yet been documented. However, the
paucity of documented and anecdotal records from the surrounding areas
would indicate that the species is not common or widespread at this
location.
The Okefenokee NWR CCP includes a strategy within the wildlife
management goal to ``develop and implement surveys to determine
distribution and population status of amphibians and reptiles,
particularly those species that are threatened, endangered, or species
of special concern.'' The CCP also includes an objective to ``identify
factors influencing declines in the refuge's fishery by examining water
chemistry, groundwater withdrawals, water quality, pH levels,
invertebrate populations, and the physical environment'' (Service 2006,
pp. 84-86). This knowledge would clearly benefit management of the
Suwannee alligator snapping turtle.
The Lower Suwannee NWR is at the mouth of the Suwannee River where
it feeds into the Gulf of Mexico. Twenty miles of the Suwannee River is
within the refuge and is suitable habitat for Suwannee alligator
snapping turtles, albeit less so as salinity increases the closer the
river gets to the Gulf of Mexico. The species is considered common
within the refuge, and nesting has been confirmed; however, the species
is not commonly seen (due to their ability to burrow into the river or
creek banks, or to sit on the bottom of the river and stay submerged
until surfacing for air is needed), and cryptic coloration when
submerged makes detection of the species very difficult (Woodward 2021,
pers. comm.). The Lower Suwannee NWR CCP includes management actions
that may benefit the species and provides goals for wildlife, habitat,
and landscape management. The CCP's objectives and strategies provide
that the refuge monitor and manage wildlife populations, manage the
habitats for endangered and threatened species and species of special
concern in the State of Florida, and promote interagency and private
landowner cooperation (Service 2001, pp. 11-22). The Lower Suwannee
River NWR provides logistical,
[[Page 53518]]
operational, in-kind, and financial support to FWC's Suwannee alligator
snapping turtle team to conduct surveys on the refuge.
Department of Defense--Moody Air Force Base
Moody Air Force Base (Base) is near Valdosta, Georgia, and has many
freshwater ponds and a large lake, Mission Lake, that drains into the
Grand Bay system. Suwannee alligator snapping turtles do not commonly
occur on the Base, but they are occasionally found. The Base's
integrated natural resources management plan (INRMP) describes
Macrochelys as occurring on the Base; however, there are no management
activities described directly for the species in the INRMP. The
Department of Defense ensures INRMPs are consistent with the Sikes Act
Improvement Act of 1997, as amended through 2010 (16 U.S.C. 670 et
seq.), which requires the preparation, implementation, update, and
review of an INRMP for each military installation in the United States
and its territories with significant natural resources.
State Protections
The Suwannee alligator snapping turtle is protected by State law in
both Florida and Georgia as a threatened species. Florida
Administrative Code rule 68A-27.003 makes it illegal to take, possess,
or sell (except as specifically permitted or authorized) species listed
as federally designated endangered or threatened species and State-
designated threatened species; this includes the species' parts, their
nests, and their eggs. Since the original 2011 biological status review
for the Suwannee alligator snapping turtle (FWC 2011, entire), two
species of alligator snapping turtle were differentiated based upon
genetic and skeletal differences (Thomas 2014, entire), necessitating
new biological status reviews of both species. During FWC's 2017
biological assessment of Macrochelys, the biological review group
determined that M. suwanniensis was distinct and warranted designation
as State-threatened based upon International Union for Conservation of
Nature (IUCN) Red List criteria (Enge et al. 2017. p. 3).
Florida developed a species action plan (SAP) that includes all
Macrochelys spp. due to their similarity in appearance, vulnerability
to deliberate human take, incidental take with fishing gear, pollution,
riverine habitat alteration, and nest predation (FWC 2018, p. iii). The
objectives of the SAP include habitat conservation and management,
population management, monitoring and research, rule and permitting
intent, law enforcement, incentives and influencing, education and
outreach, and coordination with other entities (FWC 2018, pp. 10-27).
Implementation of the Macrochelys spp. SAP is ongoing (FWC 2018,
entire). FWC has established a team of biologists who continue to study
the species to better understand the species and population trends.
Both Macrochelys suwanniensis and M. temminckii are found in
Georgia, but their ranges do not overlap. Georgia listed M. temminckii
as threatened in 1992, which at the time included both species, and
continues to cover both species as threatened. State law protects
threatened animal species by prohibiting their harassment, capture,
killing, sale, and purchase, as well as the destruction of their
habitat on public lands (Georgia Administrative Code, rule 391-4-
10-.06). In the State's wildlife action plan, the Department of Natural
Resources indicates they intend to conduct genetic, taxonomic, and
reproductive studies of high-priority species (GDNR 2015, p. D-5).
Current State regulations are intended to minimize the impact of
poaching and also contribute to the conservation of the species through
public outreach.
State and Federal Stream Protections (Deadhead Logging)
Structural features within the water are important components of
the habitat for Suwannee alligator snapping turtles. Submerged and
partially submerged vegetation provide feeding and sheltering areas for
all age classes. The structural diversity and channel stabilization
created by instream woody debris provides essential habitat for
spawning and rearing aquatic species (Bilby 1984, p. 609; Bisson et al.
1987, p. 143). Snag or woody habitat was reported as the major stable
substrate in southeastern Coastal Plain sandy-bottom streams and a site
of high invertebrate diversity and productivity (Wallace and Benke
1984, p. 1651). Wood enhances the ability of a river or stream
ecosystem to use the nutrient and energy inputs and has a major
influence on the hydrodynamic behavior of the river (Wallace and Benke
1984, p. 1643). One component of this woody habitat is deadhead logs,
which are sunken timbers from historical logging operations. Deadhead
logging is the removal of submerged cut timber from a river or creek
bed and banks. However, current State regulations minimize the impact
of deadhead logging on the Suwannee alligator snapping turtle. Florida
allows deadhead logging only with proper permits from the Florida
Department of Environmental Protection; this State agency assesses the
proposed activity's impacts on wildlife before issuing a permit.
Further, the State of Florida prohibits deadhead logging in some of the
waterways in the species' range. Georgia is not currently processing
permits; therefore, deadhead logging is not currently being permitted
in any of Georgia's waterways.
State and Federal Stream Protections (Buffers and Permits)
A buffer such as a strip of trees, plants, or grass along a stream
or wetland naturally filters out dirt and pollution from rainwater
runoff before it enters rivers, streams, wetlands, and marshes. This
vegetation not only serves as a filter for the aquatic system, but the
riparian cover influences microhabitat conditions such as in-stream
water temperature and dissolved oxygen levels. These habitat conditions
not only influence the distribution and abundance of alligator snapping
turtle prey species but also directly affect Suwannee alligator
snapping turtles. Moderate temperatures and sufficient dissolved oxygen
levels allow the turtles to remain stationary on the stream bottom for
longer periods, increasing their ambush foraging opportunities. Loss of
riparian vegetation and canopy cover result in increased solar
radiation, elevation of stream temperatures, loss of allochthonous
(organic material originating from outside the channel) food material,
and removal of submerged root systems that provide habitat for
alligator snapping turtle prey species (Allan 2004, pp. 266-267).
The Georgia Erosion and Sediment Control Act of 1975 restricts
disturbance and trimming of vegetation within a 25-ft (7.62-m) buffer
adjacent to creeks, streams, rivers, saltwater marshes, and most lakes
and ponds, and the Georgia Planning Act of 1989 requires some local
governments to adopt a 100-ft (30.48-m) buffer. Georgia also has a non-
point water pollution source management program under which the State
established and updates a nonpoint source management plan; this plan
sets long-term goals and short-term activities for the State, partners,
and stakeholders to address non-point source pollution. Although not
focused on buffers per se, the Florida Surface Water Improvement and
Management Act of 1987 addresses Statewide non-point source pollution
impacts to waterbodies on a landscape scale and partners with Federal,
State, and local governments, and the private sector to restore damaged
ecosystems and prevent pollution from storm water runoff. These State
laws provide
[[Page 53519]]
riparian protections and promote water quality, which protect potential
nesting areas for the Suwannee alligator snapping turtle.
Suwannee River Water Management District (SRWMD)
Water conservation measures restricting lawn and landscaping
irrigation can benefit the Suwannee alligator snapping turtle by
limiting water withdrawal, which directly benefits the turtle through
maintaining available habitat and supporting habitat for prey species,
and by reducing runoff of fertilizers and other turf management
chemicals that could disrupt or alter water chemistry in the streams.
The SRWMD manages the water and other related resources within the
range of the Suwannee alligator snapping turtle including the Suwannee,
Withlacoochee, Alapaha, Santa Fe, and Ichetucknee Rivers within
Florida. The agency monitors the water quantity and quality by regular
testing and reporting. It also implements water-use restrictions to
conserve freshwater resources of springs and rivers within the SRWMD.
Unnecessary water use is discouraged, and landscape irrigation
restrictions are implemented as needed, such as limiting watering to
twice per week based on district water conservation measures that apply
to residential landscaping, public or commercial recreation areas, and
businesses that are not regulated by a district-issued water use permit
(SRWMD 2021, unpaginated). Landscape irrigation accounts for the
largest percentage of household water use in the State of Florida.
Mandatory lawn and landscape watering measures are in effect throughout
the SRWMD. These restrictions contribute to maintaining healthy
groundwater level and flows.
Current Condition
The current condition for the Suwannee alligator snapping turtle
considers the current abundance, current threats, and current
conservation actions in the context of what is known about the species'
historical range. In order to determine species-specific population and
habitat factors along with threats and conservation actions influencing
the species, expert elicitation was used in the absence of available
related information. To describe Suwannee alligator snapping turtle's
current resiliency, redundancy, and representation, we assessed the
species as a single population, because there is evidence that the
turtles may move between the mouths of the Suwannee and Santa Fe Rivers
in Florida. The entire species is estimated to have an abundance of
2,000 turtles across its entire range in Georgia and Florida (Service
2022, p. 34).
The primary threats currently acting on the species include illegal
harvest, nest predation, and hook ingestion and entanglement due to
bycatch associated with freshwater fishing. Other stressors acting on
the species include historical commercial and recreational harvest,
habitat alteration and degradation, and the effects of climate change.
The species is State-listed as threatened in both Florida and Georgia.
When evaluating range expansion or constriction, recent surveys have
confirmed minimal change in the known, limited historical range.
The resiliency of the single Suwannee alligator snapping turtle
population is described according to its abundance, threats, and range
expansion or contraction. Current resilience was assessed as current
abundance, along with information about current threats, conservation
actions, and distribution serving as auxiliary information about the
causes and effects of current versus historical abundances. There is
little information with which to make rigorous comparisons between
current and historical abundances; however, population depletions
historically occurred for consumption and cumulated through the 1970s,
when turtles and turtle meat were exported regionally for commercial
use. Information about the magnitude of the changes in abundance over
time comes from anecdotal observations by trappers (Pritchard 1989, pp.
74, 76, 80, 83). The historical large-scale removal of large,
reproductive turtles from the population for commercial harvest
continues to affect the species and its ability to rebound. The species
is described as a single population with an estimated abundance of
2,000 turtles across most of its historical range. As a result of the
impacts from historical and ongoing threats, as described above, the
population size has been reduced from historical levels. This decline
has impacted the current ability of the species to withstand
environmental stochasticity. Additional information regarding current
condition descriptions is included in the SSA report (Service 2022, pp.
30-40).
The home range for Suwannee alligator snapping turtles has been
reported between 780 ft (243 m) and 6,604 ft (2,013 m) (Thomas 2014,
pp. 41-42). Turtles are not confined to any part of their range as long
as there are no physical barriers; while this species is aquatic with
the exception of nesting, these turtles are capable of moving across
land if necessary, as conditions become unsuitable or resources are
diminished. When describing the species' representation, for the
purposes of the SSA in evaluating the species' current and future
viability, the species consists of a single representative unit.
Representation is used to describe the species' ability to withstand
environmental changes over time, or the species' adaptive capacity. We
describe the species in terms of its adaptive capacity with its ability
to acclimate to environmental stressors (Service 2022, pp. 37-39). We
considered life-history attributes and assessed the species' propensity
to respond to chronic environmental influences (Thurman et al. 2020,
entire). The species has a type 3 survivorship curve, meaning only a
few individuals reach maturity with adults usually having a long life
span. This type of survivorship limits the Suwannee alligator snapping
turtle to an overall low to moderate adaptive capacity in the life-
history and demographic attributes. The high rating of its fecundity
and parity is overshadowed by the low rate of hatchling survivorship to
maturity. The low level of parental investment allows females to nest
and resume feeding and sheltering activities with minimal impacts to
their health, thus allowing for a high adaptive capacity for this
attribute. The species has a moderate to high adaptive capacity in the
distribution, movement, evolutionary potential, ecological role, and
abiotic niche attributes. The life history and demographic attributes
used in determining the species' adaptive capacity have the greatest
influence on the species' ability to respond to changes in its physical
and biological environments over time. Therefore, representation will
continue to be low to moderate.
The best available science regarding the species indicates there is
no genetic variation within the species' single population across the
species' range that would allow for delineating additional
representative units.
The Suwannee alligator snapping turtle's redundancy is likewise
limited to the single population, with an estimated abundance of 2,000
turtles, across its range. Redundancy is related to a species' response
to a catastrophic event. While there is only a single population, it is
widely distributed across the historical range; therefore, the chance
of a catastrophic event affecting the entire species is very low.
In summary, the overall current condition of the species' viability
is affected by the residual effects of historical overharvest,
historical and
[[Page 53520]]
ongoing impacts from recreational fishing, including incidental limb
line/bush hook take and bycatch, and from hook ingestion, illegal
harvest, habitat alteration, nest predation, and the species' life
history (i.e., low annual recruitment and delayed sexual maturity).
Because of these threats, and particularly the legacy effects of
historical harvest, the overall current condition is a single
population with an estimated abundance of 2,000 turtles across most of
the species' historical range. The species' resiliency is likely lower
than it was historically as a result of the loss of reproductive
females and the species' life history (long-lived, late age to sexual
maturity, low intrinsic growth rate). However, the species was not
well-studied historically, so there is little information (anecdotal
observations) with which to make comparisons between historical and
current abundance estimates. Redundancy and representation are limited,
respectively, since the species is considered a single population with
little genetic variability and there are no physical barriers to
movement.
Future Condition
The future condition of the Suwannee alligator snapping turtle is
described in detail in the SSA report (Service 2022, pp. 41-56). When
evaluating the species' future viability, we consider the current
condition of the species and the threats acting on the species to
develop a model to determine future trends of species' estimated
abundance. We applied six plausible scenarios that factored in the
estimated abundance and threats acting on the species to project the
future resiliency of the Suwannee alligator snapping turtle (see table,
below). Three scenarios consider conservation actions to be applied,
while the remaining three scenarios project conditions with no
conservation actions. Conservation actions that could decrease the
spatial extent of habitat threats include but are not limited to:
increased enforcement of state laws or law enforcement presence to
reduce poaching or bycatch on illegally set trot or limb lines,
prohibited recreational fishing or certain gear (e.g., trotlines,
hoopnets) in the Suwanee River basin, and management actions that
reduce the densities of nest predators. In addition to habitat
modification, long term female population augmentation can be
implemented by head-starting and captive breeding programs by Federal,
State, and non-governmental organizations. The actual amount that any
of these actions would influence the prevalence of threats will depend
on factors like the time, money, personnel, and conservation partners
available, but we selected a 25 percent reduction in the spatial extent
of threats to explore how much a change of that amount affected future
population dynamics (Service 2022, pp. 37-38).
To assess future conditions and the viability of the Suwannee
alligator snapping turtle, we constructed a female-only, stage-
structured matrix population model to project the population dynamics
over 50 years to encompass a two-generation period for the species and
the reliability in predicting the response to the threats in that time
frame. Species experts identified five primary threats that were likely
to reduce stage-specific survival probabilities: commercial fishing
bycatch (includes entanglement, drowning, or otherwise dying from
interaction with fishing gear; influencing hatchling, juvenile, and
adult survival), recreational fishing bycatch (has the same impacts as
commercial fishing bycatch; influenced juvenile and adult survival),
hook ingestion (surviving a bycatch event but enduring the lingering
effects of an ingested hook; influenced juvenile and adult survival),
illegal collection (i.e., poaching; influenced hatchling, juvenile, and
adult survival), and subsidized nest predators (influenced nest
survival) with two having the greatest impact (illegal harvest and nest
predation). The subsidized nest predator threat reflects additional
nest depredation beyond what would be expected from common nest
mesopredators (e.g., raccoons and opossums), with fire ants (Solenopsis
spp.) being the primary nest predator.
We used the best available information from the literature to
provide values for the population matrix and elicited data from species
experts to quantify stage-specific initial abundance, the spatial
extent of threats, and threat-specific percent reductions to survival.
To account for potential uncertainty in the effects of each threat, the
six future scenarios were divided along a spectrum: threat-induced
reductions to survival were decreased by 25 percent, were unaltered, or
were increased by 25 percent. To simulate conservation actions, the
spatial extent of each threat was either left the same or reduced by 25
percent (see table, below). The 25 percent was selected using expert
input and included a logical extent in which we would expect to see
evident impacts to the population. We used a fully stochastic
projection model that accounts for uncertainty in demographic
parameters to predict future conditions of the Suwannee alligator
snapping turtle units under the six different scenarios. We then used
the model output to predict the probability of extinction and quasi-
extinction. In the model, quasi-extinction is defined as the point in
time at which the Suwannee alligator snapping turtle population
declined to less than 5 percent of the starting abundance (females
only). Time to quasi-extinction varied across scenarios, but in
general, the Suwannee River basin is likely to reach this in 32-42
years (Service 2022, p. 46).

[[Page 53521]]
Suwannee alligator snapping turtle abundance was predicted to
decline over the next 50 years in all six scenarios. The single
population's resiliency measure also declined as abundance declined.
Given the high uncertainties parameterized in the model, the species
does not have a high likelihood of extinction in the basin within 50
years, however the loss of 95 percent of the adult female abundance is
expected to occur (quasi-extinction) Resiliency continues to decline in
all scenarios.
Future representation for Suwannee alligator snapping turtle is
expected to decline as the adaptive capacity for the distribution,
movement, evolutionary potential, ecological role, and abiotic
ecological attributes may not provide the species with the capacity to
offset the low to moderate life history and demography complexes. These
two attribute categories directly impact reproduction and the ability
to maintain or to grow the population. Representation is further
reduced by the continued impacts of human activities (e.g., unattended
fishing gear and reduced water flow) and the probability of low numbers
of adult females within the population. (Service 2022, p. 48).
Future redundancy for Suwannee alligator snapping turtle is
expected to decline over the next 50 years. Where the species persists
in the future, they are predicted to be rare and not found in resilient
groupings. The addition of conservation actions, or different
assumptions about the impact of threats on the species' demography may
alter the time to quasi- extinction by about a decade at most,
typically less. No scenarios resulted in stable or increasing
population within the Suwannee River basin (Service 2022, p. 48).
We note that, by using the SSA framework to guide our analysis of
the scientific information documented in the SSA report, we have
analyzed the cumulative effects of identified threats and conservation
actions on the species. To assess the current and future condition of
the species, we evaluate the effects of all the relevant factors that
may be influencing the species, including threats and conservation
efforts. Because the SSA framework considers not just the presence of
the factors, but to what degree they collectively influence risk to the
entire species, our assessment integrates the cumulative effects of the
factors and replaces a standalone cumulative effects analysis.
Determination of Suwannee Alligator Snapping Turtle Status
Section 4 of the Act (16 U.S.C. 1533) and its implementing
regulations (50 CFR part 424) set forth the procedures for determining
whether a species meets the definition of an endangered species or a
threatened species. The Act defines an ``endangered species'' as a
species in danger of extinction throughout all or a significant portion
of its range, and a ``threatened species'' as a species likely to
become an endangered species within the foreseeable future throughout
all or a significant portion of its range. The Act requires that we
determine whether a species meets the definition of endangered species
or threatened species because of any of the following factors: (A) The
present or threatened destruction, modification, or curtailment of its
habitat or range; (B) overutilization for commercial, recreational,
scientific, or educational purposes; (C) disease or predation; (D) the
inadequacy of existing regulatory mechanisms; or (E) other natural or
manmade factors affecting its continued existence.
Status Throughout All of Its Range
After evaluating threats to the Suwannee alligator snapping turtle
and assessing the cumulative effect of the threats under the Act's
section 4(a)(1) factors, we determined that the historical and ongoing
threats that are acting on the Suwannee alligator snapping turtle
include illegal harvest and collection (Factor B), nest predation
(Factor C), and hook ingestion and entanglement due to bycatch
associated with freshwater fishing (Factor E). While historical
activities that included removal of turtles for consumption through
recreational and commercial harvest (Factor B) continue to suppress the
viability of the species despite current harvest prohibitions, the
species is currently well-distributed across most of its historical
range. There are currently about 2,000 individuals distributed
throughout the entire species' range across southern Georgia and
northern Florida in the Suwannee River basin (Service 2022, p. 27).
The magnitude of the threats acting on the species were obtained
through expert elicitation. Incidental hooking (i.e., recreational trot
and limb lines, fishing tackle, etc.) affects between 30-75 percent of
the species. Illegal harvest or poaching across the basin ranges from
20-55 percent. Nest predation by native and exotic species affected
between 5-10 percent of the spatial extent of the species' range
(Service 2022, p. 28). Due to the delayed age of sexual maturity and a
generation time of about 28 years, the species is slow to recover from
historical harvest pressures that reduced the species' viability. As
the genus was recently split, the specific impact of large-scale
harvest on Suwannee alligator snapping turtles is unknown; however, for
Macrochelys temminckii, 22 years after M. temminckii commercial harvest
ended in Georgia, surveys conducted during 2014 and 2015 in Georgia's
Flint River revealed no significant change in abundance since 1989
(King et al. 2016, entire). We expect commercial harvest had a similar
impact on the Suwannee alligator snapping turtle as it did on the
alligator snapping turtle. Thus, despite prohibition of legal harvest
of the Suwannee alligator snapping turtle in Georgia and Florida, the
Suwannee alligator snapping turtle population will similarly be slow to
recover.
Alligator snapping turtle populations experienced severe depletion
in the past when these turtles were heavily harvested, primarily for
consumption, prior to prohibitions (Factor B). This past large-scale
removal of large, adult turtles continues to affect the current
demographics because the species has a relatively long lifespan, late
age to maturity, and low fecundity with production of a single clutch
every 1 to 2 years. The current recruitment rate has declined because
of past commercial harvest practices, which caused the large-scale loss
of adult females that have the highest reproductive potential; however,
successful reproduction is occurring. The species is not currently
impacted by commercial harvest; however, the species' resiliency is
lower than it was historically as a result of the loss of reproductive
females, low juvenile survival, and the species' life-history traits
(long-lived, late age to sexual maturity, low intrinsic growth rate).
The current estimated population size of 2,000 turtles provides
sufficient contribution to the species' current viability through
successful reproduction, albeit at a lower recruitment rate than
historically. Thus, after assessing the best available information, we
conclude that the Suwannee alligator snapping turtle is not currently
in danger of extinction throughout all of its range.
When evaluating the future viability of the species to determine
whether the species may become an endangered species within the
foreseeable future throughout its range, we found that the threats
currently acting on the species are expected to continue across its
range into the future, resulting in greater reduction of the number and
distribution of reproductive individuals.
[[Page 53522]]
We determined the appropriate timeframe for assessing whether this
species is likely to become in danger of extinction in the foreseeable
future is 50 years. Based on our knowledge of the species' life history
and the threats acting on the species, this 50-year timeframe provides
a period for which we can make reasonably reliable predictions about
the threats to the species and the species' response to those threats.
Additional information regarding the model and future scenarios is
available under ``Future Conditions'' in the SSA report (Service 2022,
pp. 51-56).
This species is highly dependent upon adult female survival to
maintain viable populations. Existing and ongoing threats affecting
adult female survival are projected to reduce recruitment to an extent
that the single population will continue to decline in the foreseeable
future. While there is uncertainty regarding the rate at which
population declines will occur, these threats are projected to drive
the species towards extinction unless reduced.
A key statutory difference between a threatened and an endangered
species is the timing of when a species may be in danger of extinction.
As described above, the Suwannee alligator snapping turtle is not in
danger of extinction throughout its range at this time. However, the
best available information shows that the species' viability is
expected to decline with quasi-extinction projected to occur within the
next 50 years under all modeled future scenarios (Service 2022, p. 41).
Based on modeling results, which address uncertainty regarding the
extent and severity of threats, resiliency is expected to decline under
all scenarios. Regardless of the scenario, the projected loss of
resiliency with limited representation and redundancy, across the range
of the species will place the Suwannee alligator snapping turtle at
risk of extinction across all of its range due to the inability of this
species to maintain a viable population in the foreseeable future.
Recreational harvest of Macrochelys spp. was prohibited in Georgia
and Florida, in 1992 and 2009, respectively, and State-listed as
threatened in Georgia (in 1992) and Florida (in 2018). Based on the
projection of future conditions, these threats will cause about a 20-
year shift in the species' resiliency, indicating these factors will
act faster on the generations in the foreseeable future.
Despite the implementation of the conservation actions described
earlier in this final rule, the lag in the species' response to
historical over-harvesting indicates other factors may be acting on the
species or additional conservation actions are needed. The future
conditions projections, which include three conservation-based
scenarios, based on the female-only matrix population model indicates a
95 percent decline in less than 50 years under the most optimistic
scenario. Therefore, given the future projections in the model, the
species is likely to become in danger of extinction within the
foreseeable future. Thus, after assessing the best available
information, we conclude that Suwannee alligator snapping turtle is
likely to become an endangered species within the foreseeable future
throughout all of its range.
Status Throughout a Significant Portion of Its Range
Under the Act and our implementing regulations, a species may
warrant listing if it is in danger of extinction or likely to become so
within the foreseeable future throughout all or a significant portion
of its range. The court in Center for Biological Diversity v. Everson,
435 F. Supp. 3d 69 (D.D.C. 2020) (Everson), vacated the provision of
the Final Policy on Interpretation of the Phrase ``Significant Portion
of Its Range'' in the Endangered Species Act's Definitions of
``Endangered Species'' and ``Threatened Species'' (Final Policy; 79 FR
37578; July 1, 2014) that provided if the Services determine that a
species is threatened throughout all of its range, the Services will
not analyze whether the species is endangered in a significant portion
of its range.
Therefore, we proceed to evaluating whether the species is
endangered in a significant portion of its range--that is, whether
there is any portion of the species' range for which both (1) the
portion is significant; and (2) the species is in danger of extinction
in that portion. Depending on the case, it might be more efficient for
us to address the ``significance'' question or the ``status'' question
first. We can choose to address either question first. Regardless of
which question we address first, if we reach a negative answer with
respect to the first question that we address, we do not need to
evaluate the other question for that portion of the species' range.
Following the court's holding in Everson, we now consider whether
there are any significant portions of the species' range where the
species is in danger of extinction now (i.e., endangered). In
undertaking this analysis for the Suwannee alligator snapping turtle,
we choose to address the status question first. We consider information
pertaining to the geographical distribution of both the species and the
threats that the species faces to identify any portions of the range
where the species is endangered.
We evaluated the range of the Suwannee alligator snapping turtle to
determine if the species is in danger of extinction now in any portion
of its range.The range of a species can theoretically be divided into
portions in an infinite number of ways. We focused our analysis on
portions of the species' range that may meet the Act's definition of an
endangered species. For the Suwannee alligator snapping turtle, we
considered whether the threats to or their effects on the species are
greater in any biologically meaningful portion of the species' range
than in other portions such that the species is in danger of extinction
now in that portion.
We examined the following threats: illegal harvest (poaching),
bycatch, habitat alteration, nest predation, and climate change,
including cumulative threats. We also considered the cumulative effects
acting on the species with additional stressors such as disease,
parasites, and contaminants. Due to the species' low population size
due to historical overharvest and limited redundancy and
representation, we find that additional stressors such as disease,
parasites, and contaminants would add to the ongoing impacts to the
species from ongoing threats further negatively affecting the species'
viability.
In the current condition analysis, as described in the SSA report,
expert elicitation values were provided to better understand the
occurrence of the threats and the collective amount of the species'
range affected (Service 2022, pp. 33-35). The impact of the threats was
estimated as a proxy for the magnitude of the threats in terms of the
amount of the entire species' range affected; these estimates do not
indicate the spatial distribution of the threats. Rather, they estimate
the percentages of the total amount of the species' range affected by
each threat noted. Bycatch from incidental hooking affects 30-75
percent of the species' range, illegal harvest affects 20-55 percent of
the species' range, and nest predation affects 5-10 percent of the
species' range; however, the impact of each threat is spread out and
not concentrated in a manner that is causing more significant declines
in any particular portion such that any portion is likely to have a
different status. Therefore, we found no portion of the Suwannee
alligator snapping turtle's range where threats are impacting
individuals differently from how they are affecting the species
elsewhere in its range, or where the biological condition
[[Page 53523]]
of the species differs from its condition elsewhere in its range such
that the status of the species in that portion differs from any other
portion of the species' range.
Therefore, no portion of the species' range provides a basis for
determining that the species is in danger of extinction in a
significant portion of its range, and we determine that the species is
likely to become in danger of extinction within the foreseeable future
throughout all of its range. This does not conflict with the courts'
holdings in Desert Survivors v. U.S. Department of the Interior, 321 F.
Supp. 3d 1011, 1070-74 (N.D. Cal. 2018) and Center for Biological
Diversity v. Jewell, 248 F. Supp. 3d 946, 959 (D. Ariz. 2017) because,
in reaching this conclusion, we did not apply the aspects of the Final
Policy, including the definition of ``significant'' that those court
decisions held to be invalid.
Determination of Status
Our review of the best scientific and commercial data available
indicates that the Suwannee alligator snapping turtle meets the Act's
definition of a threatened species. Therefore, we are listing the
Suwannee alligator snapping turtle as a threatened species in
accordance with sections 3(20) and 4(a)(1) of the Act.
Available Conservation Measures
Conservation measures provided to species listed as endangered or
threatened species under the Act include recognition as a listed
species, planning and implementation of recovery actions, requirements
for Federal protection, and prohibitions against certain practices.
Recognition through listing results in public awareness, and
conservation by Federal, State, Tribal, and local agencies, foreign
governments, private organizations, and individuals. The Act encourages
cooperation with the States and other countries and calls for recovery
actions to be carried out for listed species. The protection required
by Federal agencies, including the Service, and the prohibitions
against certain activities are discussed, in part, below.
The primary purpose of the Act is the conservation of endangered
and threatened species and the ecosystems upon which they depend. The
ultimate goal of such conservation efforts is the recovery of listed
species, so that they no longer need the protective measures of the
Act. Section 4(f) of the Act calls for the Service to develop and
implement recovery plans for the conservation of endangered and
threatened species. The goal of this process is to restore listed
species to a point where they are secure, self-sustaining, and
functioning components of their ecosystems.
The recovery planning process begins with development of a recovery
outline made available to the public soon after a final listing
determination. The recovery outline guides the immediate implementation
of urgent recovery actions while a recovery plan is being developed.
Recovery teams (composed of species experts, Federal and State
agencies, nongovernmental organizations, and stakeholders) may be
established to develop and implement recovery plans. The recovery
planning process involves the identification of actions that are
necessary to halt and reverse the species' decline by addressing the
threats to its survival and recovery. The recovery plan identifies
recovery criteria for review of when a species may be ready for
reclassification from endangered to threatened (``downlisting'') or
removal from protected status (``delisting''), and methods for
monitoring recovery progress. Recovery plans also establish a framework
for agencies to coordinate their recovery efforts and provide estimates
of the cost of implementing recovery tasks. Revisions of the plan may
be done to address continuing or new threats to the species, as new
substantive information becomes available. When completed, the recovery
outline, draft recovery plan, and the final recovery plan will be
available on our website (https://ecos.fws.gov/ecp/species/10891), or
from our Florida Ecological Services Field Office (see FOR FURTHER
INFORMATION CONTACT).
Implementation of recovery actions generally requires the
participation of a broad range of partners, including other Federal
agencies, States, Tribes, nongovernmental organizations, businesses,
and private landowners. Examples of recovery actions include habitat
restoration of native vegetation, research, captive propagation and
reintroduction, and outreach and education. The recovery of many listed
species cannot be accomplished solely on Federal lands because their
range may occur primarily or solely on non-Federal lands. To achieve
recovery of these species requires cooperative conservation efforts on
private, State, and Tribal lands.
Once this species is listed, funding for recovery actions will be
available from a variety of sources, including Federal budgets, State
programs, and cost share grants for non-Federal landowners, the
academic community, and nongovernmental organizations. In addition,
pursuant to section 6 of the Act, the States of Florida and Georgia
will be eligible for Federal funds to implement management actions that
promote the protection or recovery of the Suwannee alligator snapping
turtle. Information on our grant programs that are available to aid
species recovery can be found at https://www.fws.gov/service/financial-assistance.
Please let us know if you are interested in participating in
recovery efforts for the Suwannee alligator snapping turtle.
Additionally, we invite you to submit any new information on this
species whenever it becomes available and any information you may have
for recovery planning purposes (see FOR FURTHER INFORMATION CONTACT).
Section 7 of the Act is titled Interagency Cooperation and mandates
all Federal action agencies to use their existing authorities to
further the conservation purposes of the Act and to ensure that their
actions are not likely to jeopardize the continued existence of listed
species or adversely modify critical habitat. Regulations implementing
section 7 are codified at 50 CFR part 402.
Section 7(a)(2) states that each Federal action agency shall, in
consultation with the Secretary, ensure that any action they authorize,
fund, or carry out is not likely to jeopardize the continued existence
of a listed species or result in the destruction or adverse
modification of designated critical habitat. Each Federal agency shall
review its action at the earliest possible time to determine whether it
may affect listed species or critical habitat. If a determination is
made that the action may affect listed species or critical habitat,
formal consultation is required (50 CFR 402.14(a)), unless the Service
concurs in writing that the action is not likely to adversely affect
listed species or critical habitat. At the end of a formal
consultation, the Service issues a biological opinion, containing its
determination of whether the Federal action is likely to result in
jeopardy or adverse modification.
Examples of discretionary actions for the Suwannee alligator
snapping turtle that may be subject to consultation procedures under
section 7 are land management or other landscape-altering activities on
Federal lands administered by the Service, U.S. Forest Service, and
Department of Defense (Moody Air Force Base) as well as actions on
State, Tribal, local, or private lands that require a Federal permit
(such as a permit from the U.S. Army Corps of Engineers under section
404 of the Clean Water Act (33 U.S.C. 1251 et seq.) or a permit from
the Service under
[[Page 53524]]
section 10 of the Act) or that involve some other Federal action (such
as funding from the Federal Highway Administration, Federal Aviation
Administration, or the Federal Emergency Management Agency). Federal
actions not affecting listed species or critical habitat--and actions
on State, Tribal, local, or private lands that are not federally
funded, authorized, or carried out by a Federal agency--do not require
section 7 consultation. Federal agencies should coordinate with the
local Service Field Office (see FOR FURTHER INFORMATION CONTACT) with
any specific questions on section 7 consultation and conference
requirements.
It is the policy of the Services, as published in the Federal
Register on July 1, 1994 (59 FR 34272), to identify to the extent known
at the time a species is listed, specific activities that will not be
considered likely to result in violation of section 9 of the Act. To
the extent possible, activities that will be considered likely to
result in violation will also be identified in as specific a manner as
possible. The intent of this policy is to increase public awareness of
the effect of a listing on proposed and ongoing activities within the
range of the species. Although most of the prohibitions in section 9 of
the Act apply to endangered species, sections 9(a)(1)(G) and 9(a)(2)(E)
of the Act prohibit the violation of any regulation under section 4(d)
pertaining to any threatened species of fish or wildlife, or threatened
species of plant, respectively. Section 4(d) of the Act directs the
Secretary to promulgate protective regulations that are necessary and
advisable for the conservation of threatened species. As a result, we
interpret our policy to mean that, when we list a species as a
threatened species, to the extent possible, we identify activities that
will or will not be considered likely to result in violation of the
protective regulations under section 4(d) for that species.
Questions regarding whether specific activities would constitute a
violation of section 9 of the Act should be directed to the Florida
Ecological Services Field Office (see FOR FURTHER INFORMATION CONTACT).
II. Protective Regulations Under Section 4(d) of the Act
Background
Section 4(d) of the Act contains two sentences. The first sentence
states that the Secretary shall issue such regulations as she deems
necessary and advisable to provide for the conservation of species
listed as threatened species. Conservation is defined in the Act to
mean the use of all methods and procedures which are necessary to bring
any endangered species or threatened species to the point at which the
measures provided pursuant to the Act are no longer necessary.
Additionally, the second sentence of section 4(d) of the Act states
that the Secretary may by regulation prohibit with respect to any
threatened species any act prohibited under section 9(a)(1), in the
case of fish or wildlife, or section 9(a)(2), in the case of plants.
With these two sentences in section 4(d), Congress delegated broad
authority to the Secretary to determine what protections would be
necessary and advisable to provide for the conservation of threatened
species, and even broader authority to put in place any of the section
9 prohibitions, for a given species.
The courts have recognized the extent of the Secretary's discretion
under this standard to develop rules that are appropriate for the
conservation of a species. For example, courts have upheld, as a valid
exercise of agency authority, rules developed under section 4(d) that
included limited prohibitions against takings (see Alsea Valley
Alliance v. Lautenbacher, 2007 WL 2344927 (D. Or. 2007); Washington
Environmental Council v. National Marine Fisheries Service, 2002 WL
511479 (W.D. Wash. 2002)). Courts have also upheld 4(d) rules that do
not address all of the threats a species faces (see State of Louisiana
v. Verity, 853 F.2d 322 (5th Cir. 1988)). As noted in the legislative
history when the Act was initially enacted, ``once an animal is on the
threatened list, the Secretary has an almost infinite number of options
available to [her] with regard to the permitted activities for those
species. [She] may, for example, permit taking, but not importation of
such species, or [s]he may choose to forbid both taking and importation
but allow the transportation of such species'' (H.R. Rep. No. 412, 93rd
Cong., 1st Sess. 1973).
The provisions of this species' protective regulations under
section 4(d) of the Act are one of many tools that we will use to
promote the conservation of the Suwannee alligator snapping turtle.
Nothing in 4(d) rules change in any way the recovery planning
provisions of section 4(f) of the Act, the consultation requirements
under section 7 of the Act, or the ability of the Service to enter into
partnerships for the management and protection of the Suwannee
alligator snapping turtle. As mentioned previously in Available
Conservation Measures, Section 7(a)(2) of the Act requires Federal
agencies, including the Service, to ensure that any action they
authorize, fund, or carry out is not likely to jeopardize the continued
existence of any endangered species or threatened species or result in
the destruction or adverse modification of designated critical habitat
of such species. These requirements are the same for a threatened
species regardless of what is included in its 4(d) rule.
Section 7 consultation is required for Federal actions that ``may
affect'' a listed species regardless of whether take caused by the
activity is prohibited or excepted by a 4(d) rule (``blanket rule'' or
species-specific 4(d) rule). A 4(d) rule does not change the process
and criteria for informal or formal consultations and does not alter
the analytical process used for biological opinions or concurrence
letters. For example, as with an endangered species, if a Federal
agency determines that an action is ``not likely to adversely affect''
a threatened species, this will require the Service's written
concurrence (50 CFR 402.13(c). Similarly, if a Federal agency
determines that an action is ``likely to adversely affect'' a
threatened species, the action will require formal consultation and the
formulation of a biological opinion (50 CFR 402.14(a)). Because
consultation obligations and processes are unaffected by 4(d) rules, we
may consider developing tools to streamline future intra-Service and
inter-Agency consultations for actions that result in forms of take
that are not prohibited by the 4(d) rule (but that still require
consultation). These tools may include consultation guidance,
Information for Planning and Consultation (IPaC) effects determination
keys, template language for biological opinions, or programmatic
consultations.
Provisions of the 4(d) Rule
Exercising the Secretary's authority under section 4(d) of the Act,
we have developed a rule that is designed to address the Suwannee
alligator snapping turtle's conservation needs. As discussed previously
in Summary of Biological Status and Threats, we have concluded that the
Suwannee alligator snapping turtle is likely to become in danger of
extinction within the foreseeable future primarily due to illegal
harvest (poaching), nest predation, and bycatch-related incidents of
hook ingestion and entanglement due recreational fishing of freshwater
fish. There are other activities that could affect the species and its
habitat if they occur in areas occupied by the species, such as impacts
to water quality and quantity.
[[Page 53525]]
Due to the life-history characteristics of the Suwannee alligator
snapping turtle, specifically delayed maturity, long generation times,
and relatively low reproductive output, this species cannot sustain
significant collection from the wild, especially of adult females (Reed
et al. 2002, pp. 8-12). An adult female harvest rate of more than 2
percent per year is considered unsustainable, and harvest of this
magnitude or greater will result in significant local population
declines (Reed et al. 2002, p. 9). Although both Florida and Georgia
prohibit commercial and recreational harvest of Suwannee alligator
snapping turtles, due to the species' demography, the overall
population has not recovered from prior extensive loss of individuals
due to past over-exploitation.
Habitat alteration is also a concern for the Suwannee alligator
snapping turtle, as the species is endemic to the Suwannee River basin
and its river ecosystems, including tributary waterbodies and
associated wetland habitats (e.g., swamps, lakes, reservoirs, etc.),
where structure (e.g., tree root masses, stumps, submerged trees, etc.)
and a high percentage of canopy cover is more often selected over open
water (Howey and Dinkelacker 2009, p. 589). Suwannee alligator snapping
turtles spend the majority of their time in aquatic habitat; overland
movements are generally restricted to nesting females and juveniles
moving from the nest to water (Reed et al. 2002, p. 5). The primary
causes for habitat alteration include actions that change hydrologic
conditions to the extent that dispersal and genetic interchange are
impeded.
Some examples of activities that may alter the habitat include
dredging, deadhead logging, clearing and snagging, removal of riparian
cover, channelization, in-stream activities that result in stream bank
erosion and siltation (e.g., stream crossings, bridge replacements,
flood control structures, etc.), and changes in land use within the
riparian zone of waterbodies (e.g., clearing land for agriculture).
Deadhead logs and fallen riparian woody debris provide refugia during
low-water periods (Enge et al. 2014, p. 40), resting areas for all life
stages (Ewert et al. 2006, p. 62), and important feeding areas for
hatchlings and juveniles. The species' habitat needs concentrate around
a freshwater ecosystem that supplies both shallower water for
hatchlings and juveniles and deeper water for adults, with associated
forested habitat that is free from inundation for nesting and that
provides structure within the waterbody.
Regulating certain activities and take associated with other
activities under this 4(d) rule will prevent continued declines in
population abundance, and decrease synergistic, negative effects from
other threats.
Section 4(d) requires the Secretary to issue such regulations as
she deems necessary and advisable to provide for the conservation of
each threatened species and authorizes the Secretary to include among
those protective regulations any of the prohibitions that section
9(a)(1) of the Act prescribes for endangered species. We are not
required to make a ``necessary and advisable'' determination when we
apply or do not apply specific section 9 prohibitions to a threatened
species (In re: Polar Bear Endangered Species Act Listing and 4(d) Rule
Litigation, 818 F. Supp. 2d 214, 228 (D.D.C. 2011) (citing Sweet Home
Chapter of Cmtys. for a Great Or. v. Babbitt, 1 F.3d 1, 8 (D.C. Cir.
1993), rev'd on other grounds, 515 U.S. 687 (1995))). Nevertheless,
even though we are not required to make such a determination, we have
chosen to be as transparent as possible and explain below why we find
that the protections, prohibitions, and exceptions in this rule as a
whole satisfy the requirement in section 4(d) of the Act to issue
regulations deemed necessary and advisable to provide for the
conservation of the Suwannee alligator snapping turtle.
The protective regulations for Suwannee alligator snapping turtle
incorporate prohibitions from section 9(a)(1) to address the threats to
the species. The prohibitions of section 9(a)(1) of the Act, and
implementing regulations codified at 50 CFR 17.21, make it illegal for
any person subject to the jurisdiction of the United States to commit,
to attempt to commit, to solicit another to commit or to cause to be
committed any of the following acts with regard to any endangered
wildlife: (1) import into, or export from, the United States; (2) take
(which includes harass, harm, pursue, hunt, shoot, wound, kill, trap,
capture, or collect) within the United States, within the territorial
sea of the United States, or on the high seas; (3) possess, sell,
deliver, carry, transport, or ship, by any means whatsoever, any such
wildlife that has been taken illegally; (4) deliver, receive, carry,
transport, or ship in interstate or foreign commerce, by any means
whatsoever and in the course of commercial activity; or (5) sell or
offer for sale in interstate or foreign commerce. This protective
regulation includes all of these prohibitions because the Suwannee
alligator snapping turtle is at risk of extinction in the foreseeable
future and putting these prohibitions in place will help to prevent
further declines, preserve the species' remaining population, slow its
rate of decline, and decrease synergistic, negative effects from other
ongoing or future threats.
In particular, this 4(d) rule will provide for the conservation of
the Suwannee alligator snapping turtle by prohibiting the following
activities, unless they fall within specific exceptions or are
otherwise authorized or permitted: importing or exporting; take;
possession and other acts with unlawfully taken specimens; delivering,
receiving, carrying, transporting, or shipping in interstate or foreign
commerce in the course of commercial activity; or selling or offering
for sale in interstate or foreign commerce.
Under the Act, ``take'' means to harass, harm, pursue, hunt, shoot,
wound, kill, trap, capture, or collect, or to attempt to engage in any
such conduct. Some of these provisions have been further defined in
regulation at 50 CFR 17.3. Take can result knowingly or otherwise, by
direct and indirect impacts, intentionally or incidentally. Regulating
take of the species resulting from activities including, but not
limited to, illegal harvest (poaching), hook ingestions and
entanglement due to bycatch associated with irresponsible commercial
and recreational fishing of some species of freshwater fish
(particularly as a result of unlawful activities or abandonment of
equipment), and habitat alteration will provide for the conservation of
the species. Therefore, we are prohibiting take of the Suwannee
alligator snapping turtle, except for take resulting from those actions
and activities specifically excepted by the 4(d) rule. Exceptions to
the prohibition on take include the general exceptions to the
prohibition on take of endangered wildlife, as set forth in 50 CFR
17.21 and additional exceptions, as described below.
Despite these prohibitions regarding threatened species, we may
under certain circumstances issue permits to carry out one or more
otherwise prohibited activities, including those described above. The
regulations that govern permits for threatened wildlife state that the
Director may issue a permit authorizing any activity otherwise
prohibited with regard to threatened species. These include permits
issued for the following purposes: for scientific purposes, to enhance
propagation or survival, for economic hardship, for zoological
exhibition, for educational purposes, for incidental taking, or for
special purposes consistent with the purposes
[[Page 53526]]
of the Act (50 CFR 17.32). The statute also contains certain exemptions
from the prohibitions, which are found in sections 9 and 10 of the Act.
In addition, to further the conservation of the species, any
employee or agent of the Service, any other Federal land management
agency, the National Marine Fisheries Service, a State conservation
agency, or a federally recognized Tribe, who is designated by their
agency or Tribe for such purposes, may, when acting in the course of
their official duties, take threatened wildlife without a permit if
such action is necessary to: (i) Aid a sick, injured, or orphaned
specimen; or (ii) Dispose of a dead specimen; or (iii) Salvage a dead
specimen that may be useful for scientific study; or (iv) Remove
specimens that constitute a demonstrable but nonimmediate threat to
human safety, provided that the taking is done in a humane manner; the
taking may involve killing or injuring only if it has not been
reasonably possible to eliminate such threat by live capturing and
releasing the specimen unharmed, in an appropriate area.
We recognize the special and unique relationship that we have with
our State natural resource agency partners in contributing to
conservation of listed species. State agencies often possess scientific
data and valuable expertise on the status and distribution of
endangered, threatened, and candidate species of wildlife and plants.
State agencies, because of their authorities and their close working
relationships with local governments and landowners, are in a unique
position to assist us in implementing all aspects of the Act. In this
regard, section 6 of the Act provides that we must cooperate to the
maximum extent practicable with the States in carrying out programs
authorized by the Act. Therefore, any qualified employee or agent of a
State conservation agency that is a party to a cooperative agreement
with us in accordance with section 6(c) of the Act, who is designated
by his or her agency for such purposes, will be able to conduct
activities designed to conserve the Suwannee alligator snapping turtle
that may result in otherwise prohibited take without additional
authorization.
The 4(d) rule will also provide for the conservation of the species
by allowing exceptions that incentivize conservation actions or that,
while they may have some minimal level of take of the Suwannee
alligator snapping turtle, are not expected to rise to the level that
would have a negative impact (i.e., would have only de minimis impacts)
on the species' conservation. The exceptions to these prohibitions
include take resulting from the following activities forest management
practices that use State-approved best management practices (described
below) that are expected to have negligible impacts to the Suwannee
alligator snapping turtle and its habitat.
Pesticide and Herbicide Use: Pesticide and herbicide application
was included as an exception in the proposed 4(d) rule and after
further consideration, we are removing this exception. When considering
pesticide use, we note that the EPA has not consulted on most pesticide
registrations to date, so excepting take solely based on user
compliance with label directions and State and local regulations is not
appropriate in all situations. The Service will continue to coordinate
with EPA on further pesticide consultation and registration efforts. We
have reviewed comments provided during the public comment period on the
exception to the prohibition of take related to pesticide use and the
impact of pesticide use on the Suwannee alligator snapping turtle. We
have determined that the exception for pesticide use described in the
preamble of the proposed rule was not necessary and advisable for the
conservation of the species and have therefore not included that
exception in this final rule.
Forest Management Practices: Forest management practices that
implement State-approved BMPs designed to protect water quality and
stream and riparian habitat will avoid or minimize the effects of
habitat alterations in areas that support Suwannee alligator snapping
turtles. We considered that forest management activities may result in
removal of riparian cover or forested habitat, changes in land use
within the riparian zone, or stream bank erosion and/or siltation. We
recognize that forest management practices are widely implemented in
accordance with State-approved BMPs (as reviewed by Cristan et al.
2018, entire), and the adherence to these BMPs broadly protects water
quality, particularly related to sedimentation (as reviewed by Cristan
et al. 2016, entire; Warrington et al. 2017, entire; and Schilling et
al. 2021, entire), to an extent that does not impair the species'
conservation. Forest landowners who properly implement those BMPs are
helping conserve the Suwannee alligator snapping turtle, and this 4(d)
rule is an incentive for all landowners to properly implement
applicable State-approved BMPs to avoid any take implications. Further,
those forest landowners who are third-party-certified (attesting to the
sustainable management of a working forest) to a credible forest
management standard are providing audited certainty that BMP
implementation is taking place across the landscape.
Summary: Thus, under this final 4(d) rule, incidental take
associated with forest management practices that use State-approved
BMPs to protect water quality and stream and riparian habitat is
excepted from the prohibitions.
III. Critical Habitat
Background
Section 4(a)(3) of the Act requires that, to the maximum extent
prudent and determinable, we designate a species' critical habitat
concurrently with listing the species. Critical habitat is defined in
section 3 of the Act as:
(1) The specific areas within the geographical area occupied by the
species, at the time it is listed in accordance with the Act, on which
are found those physical or biological features
(a) Essential to the conservation of the species, and
(b) Which may require special management considerations or
protection; and
(2) Specific areas outside the geographical area occupied by the
species at the time it is listed, upon a determination that such areas
are essential for the conservation of the species.
Our regulations at 50 CFR 424.02 define the geographical area
occupied by the species as an area that may generally be delineated
around species' occurrences, as determined by the Secretary (i.e.,
range). Such areas may include those areas used throughout all or part
of the species' life cycle, even if not used on a regular basis (e.g.,
migratory corridors, seasonal habitats, and habitats used periodically,
but not solely by vagrant individuals).
Conservation, as defined under section 3 of the Act, means to use
and the use of all methods and procedures that are necessary to bring
an endangered or threatened species to the point at which the measures
provided pursuant to the Act are no longer necessary. Such methods and
procedures include, but are not limited to, all activities associated
with scientific resources management such as research, census, law
enforcement, habitat acquisition and maintenance, propagation, live
trapping, and transplantation, and, in the extraordinary case where
population pressures within a given ecosystem cannot be otherwise
relieved, may include regulated taking.
Critical habitat receives protection under section 7 of the Act
through the
[[Page 53527]]
requirement that Federal agencies ensure, in consultation with the
Service, that any action they authorize, fund, or carry out is not
likely to result in the destruction or adverse modification of critical
habitat. The designation of critical habitat does not affect land
ownership or establish a refuge, wilderness, reserve, preserve, or
other conservation area. Such designation also does not allow the
government or public to access private lands. Such designation does not
require implementation of restoration, recovery, or enhancement
measures by non-Federal landowners. Rather, designation requires that,
where a landowner requests Federal agency funding or authorization for
an action that may affect an area designated as critical habitat, the
Federal agency consult with the Service under section 7(a)(2) of the
Act. If the action may affect the listed species itself (such as for
occupied critical habitat), the Federal action agency would have
already been required to consult with the Service even absent the
critical habitat designation because of the requirement to ensure that
the action is not likely to jeopardize the continued existence of the
species. Even if the Service were to conclude after consultation that
the proposed activity is likely to result in destruction or adverse
modification of the critical habitat, the Federal action agency and the
landowner are not required to abandon the proposed activity, or to
restore or recover the species; instead, they must implement
``reasonable and prudent alternatives'' to avoid destruction or adverse
modification of critical habitat.
Under the first prong of the Act's definition of critical habitat,
areas within the geographical area occupied by the species at the time
it was listed are included in a critical habitat designation if they
contain physical or biological features (1) which are essential to the
conservation of the species and (2) which may require special
management considerations or protection. For these areas, critical
habitat designations identify, to the extent known using the best
scientific data available, those physical or biological features that
are essential to the conservation of the species (such as space, food,
cover, and protected habitat).
Under the second prong of the Act's definition of critical habitat,
we can designate critical habitat in areas outside the geographical
area occupied by the species at the time it is listed, upon a
determination that such areas are essential for the conservation of the
species.
Section 4 of the Act requires that we designate critical habitat on
the basis of the best scientific data available. Further, our Policy on
Information Standards Under the Endangered Species Act (published in
the Federal Register on July 1, 1994 (59 FR 34271)), the Information
Quality Act (section 515 of the Treasury and General Government
Appropriations Act for Fiscal Year 2001 (Pub. L. 106-554; H.R. 5658)),
and our associated Information Quality Guidelines provide criteria,
establish procedures, and provide guidance to ensure that our decisions
are based on the best scientific data available. They require our
biologists, to the extent consistent with the Act and with the use of
the best scientific data available, to use primary and original sources
of information as the basis for recommendations to designate critical
habitat.
Prudency Determination
Section 4(a)(3) of the Act, as amended, and implementing
regulations (50 CFR 424.12) require that, to the maximum extent prudent
and determinable, the Secretary shall designate critical habitat at the
time the species is determined to be an endangered species or a
threatened species. On April 5, 2024, we published a final rule that
revised our regulations at 50 CFR part 424 to further clarify when
designation of critical habitat may not be prudent (89 FR 24300). Our
regulations (50 CFR424.12(a)(1)) state that designation of critical
habitat may not be prudent in circumstances such as, but not limited
to, the following:
(i) The species is threatened by taking or other human activity and
identification of critical habitat can be expected to increase the
degree of such threat to the species;
(ii) The present or threatened destruction, modification, or
curtailment of a species' habitat or range is not a threat to the
species;
(iii) Areas within the jurisdiction of the United States provide no
more than negligible conservation value, if any, for a species
occurring primarily outside the jurisdiction of the United States; or
(iv) No areas meet the definition of critical habitat.
In the April 7, 2021, proposed rule (86 FR 18014), we determined
that designation of critical habitat would not be prudent. However, we
invited public comment and requested information on the factors that
the regulations identify as reasons why designation of critical habitat
may be not prudent, and the extent to which designation might increase
threats to the species, as well as the possible benefits of critical
habitat designation to the Suwannee alligator snapping turtle.
During the comment period, we did not receive any comments that
caused us to change the not-prudent determination or our rationale for
it. The not-prudent determination for the proposed rule was based on
increasing the threat of collection as described in 50 CFR
424.12(a)(1)(i). This component of the latest regulatory language has
not changed from the regulatory language used in the proposed rule. The
non-prudent determination for this final rule is the same as the
proposed because the threat of collection is one of the factors in
determining prudency that remained consistent in the previous
regulations and the current regulations
Therefore, after review and consideration of the comments we
received, we now make a final determination that the designation of
critical habitat is not prudent, in accordance with 50 CFR
424.12(a)(1), because the Suwannee alligator snapping turtle faces the
threat of poaching, and designation can reasonably be expected to
increase the degree of this threat to the species by making location
information more readily available.
Required Determinations
National Environmental Policy Act (42 U.S.C. 4321 et seq.)
Regulations adopted pursuant to section 4(a) of the Act are exempt
from the National Environmental Policy Act (NEPA; 42 U.S.C. 4321 et
seq.) and do not require an environmental analysis under NEPA. We
published a notice outlining our reasons for this determination in the
Federal Register on October 25, 1983 (48 FR 49244). This includes
listing, delisting, and reclassification rules, as well as critical
habitat designations and species-specific protective regulations
promulgated concurrently with a decision to list or reclassify a
species as threatened. The courts have upheld this position (e.g.,
Douglas County v. Babbitt, 48 F.3d 1495 (9th Cir. 1995) (critical
habitat); Center for Biological Diversity v. U.S. Fish and Wildlife
Service, 2005 WL 2000928 (N.D. Cal. Aug. 19, 2005) (concurrent 4(d)
rule)).
Government-to-Government Relationship With Tribes
In accordance with the President's memorandum of April 29, 1994
(Government-to-Government Relations with Native American Tribal
Governments; 59 FR 22951), Executive Order 13175 (Consultation and
Coordination with Indian Tribal
[[Page 53528]]
Governments), and the Department of the Interior's manual at 512 DM 2,
we readily acknowledge our responsibility to communicate meaningfully
with federally recognized Tribes on a government-to-government basis.
In accordance with Secretary's Order 3206 of June 5, 1997 (American
Indian Tribal Rights, Federal-Tribal Trust Responsibilities, and the
Endangered Species Act), we readily acknowledge our responsibilities to
work directly with Tribes in developing programs for healthy
ecosystems, to acknowledge that Tribal lands are not subject to the
same controls as Federal public lands, to remain sensitive to Indian
culture, and to make information available to Tribes.
Upon the initiation of the SSA process, we contacted Tribes within
the range of Suwannee alligator snapping turtle and additional Tribes
of interest to inform them of our intent to complete an SSA for the
