Endangered and Threatened Wildlife
and Plants; Threatened Species Status
With Section 4(d) Rule for the Upper
Coosa River Distinct Population
Segment of Frecklebelly Madtom and
Designation of Critical Habitat
Fish and Wildlife Service,
Interior.
ACTION: Proposed rule.
AGENCY:
We, the U.S. Fish and
Wildlife Service (Service), announce a
12-month finding on a petition to list
the frecklebelly madtom (Noturus
munitus), a fish species from Louisiana,
Mississippi, Alabama, Georgia, and
Tennessee, as an endangered or
threatened species and designate critical
habitat under the Endangered Species
Act of 1973, as amended (Act). After a
review of the best available scientific
and commercial information, we find
that listing the frecklebelly madtom as
an endangered or a threatened species
throughout all of its range is not
warranted. However, we determined
that listing is warranted for a distinct
population segment (DPS) of the
frecklebelly madtom in the Upper Coosa
River in Georgia and Tennessee.
Accordingly, we propose to list the
Upper Coosa River DPS of the
frecklebelly madtom as a threatened
species with a rule issued under section
4(d) of the Act (‘‘4(d) rule’’). If we
finalize this rule as proposed, it would
add this DPS to the List of Endangered
and Threatened Wildlife and extend the
Act’s protections to the DPS. We also
propose to designate critical habitat for
the Upper Coosa River DPS under the
Act. In total, approximately 134 river
miles (216 kilometers) in Georgia and
Tennessee fall within the boundaries of
the proposed critical habitat
designation. We also announce the
availability of a draft economic analysis
(DEA) of the proposed designation of
critical habitat for the Upper Coosa
River DPS.
DATES: We will accept comments
received or postmarked on or before
January 19, 2021. Comments submitted
electronically using the Federal
eRulemaking Portal (see ADDRESSES,

Executive Summary
Why we need to publish a rule. Under
the Act, if we determine that a species
may be an endangered or threatened
species throughout all or a significant
portion of its range, we are required to
promptly publish a proposal in the
Federal Register and make a
determination on our proposal within 1
year. To the maximum extent prudent
and determinable, we must designate
critical habitat for any species that we
determine to be an endangered or
threatened species under the Act.
Listing a species as an endangered or
threatened species and designation of
critical habitat can only be completed
by issuing a rule.
What this document does. This rule
proposes the listing of the Upper Coosa
River distinct population segment (DPS)
of frecklebelly madtom as a threatened
species with a rule under section 4(d) of
the Act and proposes the designation of
critical habitat for the DPS.
The basis for our action. Under the
Act, we may determine that a species is
an endangered or threatened species
because of 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 factors driving
the status of the Upper Coosa River DPS
are habitat destruction and degradation
caused by agriculture and developed
land uses resulting in poor water quality
(Factor A).
Section 4(a)(3) of the Act requires the
Secretary of the Interior (Secretary) to
designate critical habitat concurrent
with listing to the maximum extent
prudent and determinable. Section
3(5)(A) of the Act defines critical habitat
as (i) the specific areas within the
geographical area occupied by the
species, at the time it is listed, on which
are found those physical or biological
features (I) essential to the conservation
of the species and (II) which may
require special management
considerations or protections; and (ii)
specific areas outside the geographical
area occupied by the species at the time
it is listed, upon a determination by the
Secretary that such areas are essential
for the conservation of the species.
Section 4(b)(2) of the Act states that the
Secretary must make the designation on
the basis of the best scientific data
available and after taking into
consideration the economic impact, the
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
impact on national security, and any
other relevant impacts of specifying any
particular area as critical habitat.
Peer review. 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 the expert
opinions of 10 appropriate specialists
regarding the SSA report. We received
responses from two specialists, and
their input informed this proposed rule.
The purpose of peer review is to ensure
that our listing determinations, critical
habitat designations, and 4(d) rules are
based on scientifically sound data,
assumptions, and analyses. The peer
reviewers have expertise in the biology,
habitat, and threats to the species.
Because we will consider all
comments and information we receive
during the comment period, our final
determinations may differ from this
proposal. Based on the new information
we receive (and any comments on that
new information), we may conclude that
the Upper Coosa River DPS is
endangered instead of threatened, or we
may conclude that the DPS does not
warrant listing. Such final decisions
would be a logical outgrowth of this
proposal, as long as we: (1) Base the
decisions on the best scientific and
commercial data available after
considering all of the relevant factors;
(2) do not rely on factors Congress has
not intended us to consider; and (3)
articulate a rational connection between
the facts found and the conclusions
made, including why we changed our
conclusion.
Information Requested
We intend that any final action
resulting from this proposed rule will be
based on the best scientific and
commercial data available and be as
accurate and as effective as possible.
Therefore, we request comments or
information from other concerned
governmental agencies, Native
American Tribes, the scientific
community, industry, or any other
interested parties concerning this
proposed rule.
We particularly seek comments
concerning:
(1) The frecklebelly madtom’s biology,
range, distribution, and population
trends, particularly in the upper Coosa
River watershed in Georgia and
Tennessee, including:
(a) Biological or ecological
requirements of the frecklebelly
madtom, including habitat requirements
for feeding, breeding, and sheltering;
(b) Genetics and taxonomy;
VerDate Sep<11>2014

Jkt 253001
(c) Historical and current range,
including distribution patterns;
(d) Historical and current population
levels, and current and projected trends;
and
(e) Past and ongoing conservation
measures for the frecklebelly madtom,
its habitat, or both.
(2) Factors that may affect the
continued existence of the frecklebelly
madtom, which may include habitat
modification or destruction,
overutilization, disease, predation, the
inadequacy of existing regulatory
mechanisms, or other natural or
manmade factors.
(3) Biological, commercial trade, or
other relevant data concerning any
threats (or lack thereof) to the
frecklebelly madtom and existing
regulations that may be addressing those
threats.
(4) Additional information concerning
the historical and current status, range,
distribution, and population size of the
frecklebelly madtom, and specifically
the Upper Coosa River DPS, including
the locations of any additional
populations of the frecklebelly madtom.
(5) Information on regulations that are
necessary and advisable to provide for
the conservation of the Upper Coosa
River DPS of frecklebelly madtom and
that the Service can consider in
developing a 4(d) rule for the DPS,
including information concerning the
extent to which we should include any
of the section 9 prohibitions in the 4(d)
rule or whether any other forms of take
should be excepted from the
prohibitions in the 4(d) rule. We
particularly seek comments concerning:
(a) Whether we should add a
provision to except incidental take
resulting from silvicultural practices
and forest management activities that
implement State-approved best
management practices and comply with
forest practice guidelines related to
water quality standards.
(b) Whether there are additional
provisions the Service may wish to
consider for the section 4(d) rule in
order to conserve, recover, and manage
the Upper Coosa River DPS.
(6) The reasons why we should or
should not designate habitat as ‘‘critical
habitat’’ under section 4 of the Act (16
U.S.C. 1531 et seq.), including
information to inform the following
factors that the regulations identify as
reasons why designation of critical
habitat may be not prudent:
(a) 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;
PO 00000
Frm 00003
Fmt 4701
Sfmt 4702
74051
(b) The present or threatened
destruction, modification, or
curtailment of a species’ habitat or range
is not a threat to the species, or threats
to the species’ habitat stem solely from
causes that cannot be addressed through
management actions resulting from
consultations under section 7(a)(2) of
the Act; or
(c) No areas meet the definition of
critical habitat.
(7) Specific information on:
(a) The amount and distribution of
Upper Coosa River DPS habitat;
(b) Information on the physical or
biological features essential to the
conservation of the DPS;
(c) What areas, that were occupied at
the time of listing and that contain the
physical or biological features essential
to the conservation of the DPS, such as
the Coosawattee River in Georgia,
should be included in the critical
habitat designation and why;
(d) The methods we used, particularly
the use of environmental DNA, to
identify occupied critical habitat for
each of the units;
(e) Special management
considerations or protection that may be
needed in critical habitat areas we are
proposing, including managing for the
potential effects of climate change; and
(f) What areas not occupied at the
time of listing are essential for the
conservation of the DPS and should be
included as critical habitat and why. We
particularly seek comments:
(i) Regarding whether occupied areas
are adequate for the conservation of the
DPS; and
(ii) Providing specific information
regarding whether or not unoccupied
areas would, with reasonable certainty,
contribute to the conservation of the
DPS and contain at least one physical or
biological feature essential to the
conservation of the DPS.
(8) Land use designations and current
or planned activities in the subject areas
and their possible impacts on proposed
critical habitat.
(9) Any probable economic, national
security, or other relevant impacts of
designating any area that may be
included in the final designation, and
the related benefits of including or
excluding specific areas.
(10) Information on the extent to
which the description of probable
economic impacts in the draft economic
analysis is a reasonable estimate of the
likely economic impacts.
(11) Whether any specific areas we are
proposing for critical habitat
designation should be considered for
exclusion under section 4(b)(2) of the
Act, and whether the benefits of
potentially excluding any specific area
E:\FR\FM\19NOP2.SGM
19NOP2
74052
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
outweigh the benefits of including that
area under section 4(b)(2) of the Act.
(12) Whether we could improve or
modify our approach to designating
critical habitat in any way to provide for
greater public participation and
understanding, or to better
accommodate public concerns and
comments.

Previous Federal Actions
On April 20, 2010, we were petitioned
by the Center for Biological Diversity
and others to list 404 aquatic species in
the southeastern United States,
including the frecklebelly madtom,
under the Act. In response to the
petition, we completed a partial 90-day
finding on September 27, 2011 (76 FR
59836), in which we announced our
finding that the petition contained
substantial information indicating that
listing may be warranted for numerous
species, including the frecklebelly
madtom. On April 15, 2015, the Center
for Biological Diversity amended a
complaint against the Service for failure
to complete a 12-month finding for the
frecklebelly madtom in accordance with
statutory deadlines. On September 9,
2015, the Service and the Center for
Biological Diversity filed stipulated
settlements in the District of Columbia,
agreeing that the Service would submit
to the Federal Register a 12-month
finding for the frecklebelly madtom no
later than September 30, 2020 (Center
for Biological Diversity v. Jewell, case
1:15–CV–00229–EGS). This document
constitutes our concurrent 12-month
warranted petition finding, proposed
listing rule, and proposed critical
habitat rule.
Supporting Documents
An SSA team prepared an SSA report
for the frecklebelly madtom. 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. The
Service sent the SSA report to 10
independent peer reviewers and
received 2 responses. The Service also
sent the SSA report for review to 13
partners, including scientists with
expertise in fish biology, stream and
riverine ecology, and factors negatively
and positively affecting the species. We
received review from two partners,
Mississippi Museum of Natural Science
and Georgia Department of Natural
Resources.
I. Proposed Listing Determination
Background
A thorough review of the taxonomy,
life history, and ecology of the
frecklebelly madtom (Noturus munitus)
is presented in the SSA report (version
PO 00000
Frm 00004
Fmt 4701
Sfmt 4702
1.2; Service 2020, pp. 5–15; available at
https://www.fws.gov/southeast/ and at
https://www.regulations.gov under
Docket No. FWS–R4–ES–2020–0058).
The frecklebelly madtom is a catfish
species that inhabits the main channels
and larger tributaries of large river
systems in Louisiana, Mississippi,
Alabama, Georgia, and Tennessee. The
species has a broad but disjunct
distribution across the Pearl River
watershed and Mobile River Basin, with
populations in the Pearl River and
Bogue Chitto River in the Pearl River
watershed and the Upper Tombigbee,
Alabama, Cahaba, Etowah, and
Conasauga river systems in the Mobile
River Basin (Piller et al. 2004, p. 1004;
Bennett et al. 2010, pp. 507–508).
Throughout its range, the frecklebelly
madtom primarily occupies streams and
rivers within the Gulf Coastal Plain
physiographic province; however, it
also occurs in the Ridge and Valley
physiographic province in the
Conasauga River and Piedmont Upland
physiographic province in the Etowah
River (Mettee et al. 1996, pp. 408–409).
The frecklebelly madtom is a small,
stout catfish reaching 99 millimeters
(mm) (3.9 inches (in)) in length (Etnier
and Starnes 1993, p. 324) and
distinctively marked with dark saddles
(Suttkus and Taylor 1965, p. 171). The
color of the frecklebelly madtom is a
mixture of light yellows with brownish
patches and a combination of many
scattered specks or freckles on the
underside, which provides camouflage
in its preferred habitats and inspired its
common name (Suttkus and Taylor
1965, p. 176; Vincent 2019,
unpaginated). The fins’ colors are
typically mottled or blotched (Etnier
and Starnes 1993, p. 324). The
frecklebelly madtom is armed with
venomous pectoral and dorsal spines
used to defend against predation and
has barbels around the mouth that act as
sensory organs.
The species belongs in the family
Ictaluridae, and all species in the genus
Noturus, referred to as madtoms, are
diminutive and possess long and low
adipose fins (i.e., found on the back
behind the dorsal fin) (Page and Burr
2011, p. 207). The currently recognized
taxon is Noturus munitus (Suttkus and
Taylor 1965, entire; Rhode 1978, p.
465). Since the time of description,
uncertainty regarding the taxonomic
status of some populations of
frecklebelly madtom has arisen. In 1998,
the name ‘‘Coosa madtom’’ (Noturus sp.
cf. N. munitus) was coined to describe
the madtoms, previously identified as
frecklebelly madtom, in the Conasauga
and Etowah Rivers that were
morphologically distinct from the
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
frecklebelly madtom found elsewhere
(Boschung and Mayden 2004, p. 347;
Neely 2018, p. 1). However, a recent
analysis of the existing morphological
and genetic datasets documented
substantial genetic divergence between
all populations from distinct
watersheds. The Pearl and Mobile basin
populations exhibited the strongest
genetic divergence, followed by
Tombigbee and Alabama River (Cahaba
and Coosa) populations (Neely 2018,
entire). The Cahaba and Coosa
populations exhibited the lowest genetic
differentiation and could not be reliably
diagnosed based on morphology.
Therefore, because the data indicate
divergence between populations but do
not support the description of distinct
subspecies or species, we consider each
population of frecklebelly madtom to be
a separate evolutionary significant unit
(ESU) (Neely 2018, p. 10) for purposes
of this determination. ESUs are partially
defined as a population that ‘‘represents
an important component in the
evolutionary legacy of a species’’
(Waples 1991, p. 12). Because evolution
is a continual process, elements that
represent a species’ evolutionary legacy
are also important elements of a species’
adaptive capacity. Therefore, the ESUs
recommended by Neely (2018, entire)
were used to inform our analysis on the
frecklebelly madtom’s representation,
an attribute of the species’ viability
(Service 2020, pp. 3, 35–37).
For the frecklebelly madtom to
survive and reproduce, individuals need
suitable habitat that supports essential
life functions at all life stages. Three
elements appear to be essential to the
survival and reproduction of
individuals: Flowing water, stable
substrate, and aquatic vegetation. The
frecklebelly madtom typically occurs
over firm gravel substrates, such as
shoals and riffles, in small to large swiftflowing streams often associated with
large rivers and their tributaries (Suttkus
and Taylor 1965, pp. 177–178; Mettee et
al. 1996, p. 409; Vincent 2019,
unpaginated). However, the species will
use streams dominated with sand
substrates if suitable cover such as large
woody debris is present (Wagner 2019,
pers. comm.). Cover is an important
habitat factor for the species, as it
provides for concealment against
predators (Vincent 2019, unpaginated),
foraging habitat, and nesting habitat. In
some rivers where the species is found,
the frecklebelly madtom is often
associated with aquatic vegetation, such
as river weed (Podostemum), and under
large, flat rocks (Mettee et al. 1996, p.
409, Freeman et al. 2003, p. iii). In the
upper Etowah and Conasauga Rivers,
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
the frecklebelly madtom has been
collected in moderate to swift currents
over boulders, rubble, cobble, and
coarse gravel and around concentrations
of river weed.
The frecklebelly madtom is likely
nocturnal and most active at night. The
species has a lifespan of approximately
5 years (Mettee et al. 1996, pp. 408–409)
and is reproductively mature in the
second summer after birth, similar to
other madtom species (Burr and
Stoeckel 1999, p. 65). In the wild,
reproduction is thought to occur
between June and July (Trauth et al.
1981, p. 66). At the Private John Allen
National Fish Hatchery in Tupelo, MS,
frecklebelly madtoms have been
observed spawning between the end of
May to mid-August (Schwarz 2020,
unpublished report). The female
produces 50 to 70 eggs, which are
released all at one time (Trauth et al.
1981, p. 66). Fecundity in madtoms is
among the lowest for North American
freshwater fishes due to their small size,
relatively large egg size, and high level
of parental care given to the fertilized
eggs (embryos) and larvae (Dinkins and
Shute 1996, pp. 58–60; Burr and
Stoeckel 1999, pp. 66–67). However, the
frecklebelly madtom is considered
highly fecund for a madtom and among
the highest fecundity known for its
subgenus, Rabida (Bennett et al. 2010,
p. 507).
Nesting sites for madtoms are
typically cavities under natural material
(rocks, logs, empty mussel shells) or
human litter (inside cans or bottles,
under boards). Madtoms construct
cavities on the bottoms of streams by
moving substrate using their heads to
push gravel or their mouths to carry and
transport gravel and pebbles (Vincent
2019, unpaginated). Both males and
females may construct nesting cavities
(Burr and Stoeckel 1999, p. 69).
The species is an opportunistic
insectivore feeding on a variety of
aquatic insects and larvae, including
caddisflies, mayflies, blackflies, and
midges (Miller 1984, p. 9). There appear
to be seasonal shifts in food preference
between the sexes, with males typically
preferring caddisflies in the fall months,
and the females preferring midges
during the same time (Miller 1984, p.
10).
Regulatory and Analytical Framework
Regulatory Framework
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 is an
‘‘endangered species’’ or a ‘‘threatened
species.’’ The Act defines an
PO 00000
Frm 00005
Fmt 4701
Sfmt 4702
74053
‘‘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
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
expected response by the species, 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. The term
‘‘foreseeable future’’ extends only so far
into the future as the Service can
reasonably determine that both the
future threats and the species’ responses
to those threats are likely. In other
words, the foreseeable future is the
period of time in which we can make
reliable predictions. ‘‘Reliable’’ does not
mean ‘‘certain’’; it means sufficient to
provide a reasonable degree of
confidence in the prediction. Thus, a
prediction is reliable if it is reasonable
to depend on it when making decisions.
It is not always possible or necessary
to define foreseeable future as a
particular number of years. Analysis of
the foreseeable future uses the best
scientific and commercial data available
and should consider the timeframes
applicable to the relevant threats and to
the species’ likely responses to those
threats in view of its life-history
characteristics. Data that are typically
relevant to assessing the species’
biological response include speciesspecific factors such as lifespan,
reproductive rates or productivity,
certain behaviors, and other
demographic factors.
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 a decision by the
Service on whether the species should
be proposed for listing as an endangered
or threatened species under the Act. It
does, however, 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. The following is a summary of
the key results and conclusions from the
SSA report; the full SSA report can be

To assess frecklebelly madtom
viability, we used the three conservation
biology principles of resiliency,
redundancy, and representation (Shaffer
and Stein 2000, pp. 306–310). Briefly,
resiliency supports the ability of the
species to withstand environmental and
demographic stochasticity (for example,
wet or dry, warm or cold years),
redundancy supports the ability of the
species to withstand catastrophic events
(for example, droughts, large pollution
events), and representation supports the
ability of the species to adapt over time
to long-term changes in the environment
(for example, climate changes). In
general, the more resilient and
redundant a species is and the more
representation it has, the more likely it
is to sustain populations over time, even
under changing environmental
conditions. 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.
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. For frecklebelly madtom
populations to be resilient, the needs of
individuals (flowing water, substrate,
and aquatic vegetation) must be met at
a large scale. Stream reaches with
suitable habitat must be large enough to
support an appropriate number of
individuals to avoid issues associated
with small population sizes, such as
inbreeding depression. At the species
level, the frecklebelly madtom needs a
sufficient number and distribution of
PO 00000
Frm 00006
Fmt 4701
Sfmt 4702
healthy populations to withstand
environmental stochasticity (resiliency)
and catastrophes (redundancy) and to
adapt to biological and physical changes
in its environment (representation). To
evaluate the current and future viability
of the frecklebelly madtom, we assessed
a range of conditions to allow us to
consider the current and future effects
on resiliency, representation, and
redundancy.
Delineating Representation and
Resilience Units
We delineated representation and
resilience units for the frecklebelly
madtom. Representation units were
delineated to describe the breadth of
known genetic, phenotypic, and
ecological diversity within the species.
There is evidence of differentiation in
habitat use, morphology, and genetics
for areas that the frecklebelly madtom
occupies, which are disconnected
spatially across the landscape.
Resilience units were delineated to
describe at a local scale how the species
withstands stochastic events. These
resilience units are not meant to
represent individual populations as they
may represent multiple or portions of
groups of demographically linked
interbreeding individuals.
In total, we identified six
representation units for the frecklebelly
madtom: Pearl River (A), upper
Tombigbee River (B), lower Tombigbee/
Alabama Rivers (C), Alabama River (D),
Cahaba River (E), and upper Coosa River
(F) (see table 1, below). Four
representation units (Pearl River (A),
upper Tombigbee River (B), Cahaba
River (E), and upper Coosa River (F)) are
the ESUs based on the evaluation of
morphometric and genetic datasets
(Neely 2018, entire). Morphometric and
genetic data from the remaining two
representation units (lower Tombigbee/
Alabama Rivers (C) and Alabama River
(D)) were not available to be analyzed in
the 2018 study (Neely 2018, entire) and,
therefore, were not identified as ESUs in
that study.
The lower Tombigbee/Alabama Rivers
(C) and Alabama River (D)
representation units reflect occurrences
of the species in the Mobile River Basin
that are the farthest downstream and
within a large river habitat type that is
distinct from the remainder of the units
in the Mobile River Basin. Furthermore,
these reaches are disconnected from the
nearest adjacent representation units by
dams that act as dispersal barriers for
the species. Therefore, these reaches are
assessed as two individual
representation units. The Alabama River
(D) representation unit consists of a
single HUC 10 watershed that is isolated
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
from other representation units by
dams. The remaining unit, lower
Tombigbee/Alabama Rivers (C), is
disconnected from the upper Tombigbee
River and Alabama River units by dams.
Resilience units were delineated as
aggregations of adjacent U.S. Geological
Survey Hydrological Unit Code (HUC)
10 watershed boundaries that contain a
frecklebelly madtom observation and
are not disconnected by dams or other
major habitat alterations that may
present a barrier to movement. While
resiliency is typically assessed at the
scale of a population, there was little
information to delineate populations of
the frecklebelly madtom. By using HUC
10 watersheds, we are able to delineate
resilience units that can be measured
74055
and evaluated at a local scale similar to
that we would expect for a population.
We determined this to be the most
appropriate scale for measuring
resiliency. We identified 16 resilience
units consisting of 66 HUC10
watersheds across the range of the
frecklebelly madtom (see table 1,
below).

Methods To Assess Current Condition
We assessed the current resiliency
(ability of populations to withstand
stochastic events) of frecklebelly
madtom resilience units by considering
occurrence data throughout the species’
range. We used occurrence data to
estimate range extent and range
geometry (i.e., number of named streams
with occurrences). These metrics can be
useful for evaluating resiliency, as larger
areas of occupied habitat and multiple
occupied streams (more complex
ranges) are more robust to stochastic
events (i.e., a single more localized
event would be unlikely to negatively
affect the entire population or unit if
many and larger reaches of streams were
occupied). Occurrence data for the
frecklebelly madtom are only available
for five of the six representation units:
The Pearl River (A), upper Tombigbee
River (B), Alabama River (D), Cahaba
River (E), and upper Coosa River (F).
Therefore, we conducted our assessment
of occurrences only on resilience units
within those representation units, and
we categorized current resiliency into
high, moderate, low, or likely extirpated
conditions, based on our evaluation of
total number of occurrences, the number
of occupied stream reaches, the length
of discrete stream reaches, and the
maximum occupied stream reach

estimate and available literature
(Service 2020, pp. 34–53). The Lower
Tombigbee/Alabama Rivers (C)
representation unit was categorized to
have unknown resiliency (see
discussion below regarding
environmental DNA).
Environmental DNA (eDNA, which is
DNA that is shed into the environment
by an organism during its life) belonging
to the frecklebelly madtom was
collected in the Conasauga River (F1),
Coosawattee River (F2), Etowah River
(F3), and portions of the lower Alabama
River (C2) and lower Tombigbee River
(C1) (Freeman and Bumpers 2018,
entire; Janosik and Whittaker 2018,
entire). Within the Coosawattee River
(F2), the lower Alabama River (C2), and
the lower Tombigbee River (C1), eDNA
is the only evidence of the species’
presence within the period of record
(1950–2019). Collecting and analyzing
water samples for eDNA provides a
means of rapidly surveying aquatic
habitats to help identify potentially
occupied sites for a species. However,
uncertainty of these data revolves
around the origin and fate of the
individuals that shed the DNA and the
length of time the eDNA persists in the
environment. For the purposes of this
analysis, we used eDNA data as
evidence to support our conclusion that
PO 00000
Frm 00007
Fmt 4701
Sfmt 4702
the probability of the species being
present in a particular unit is greater
than zero. As described above, we used
occurrence data to assess resiliency. If
units are known only from eDNA data,
an unknown resiliency was determined
since we have no occurrence
information.
We assessed representation for the
frecklebelly madtom as the number of
resilient populations within a
representation unit. Finally, we assessed
frecklebelly madtom redundancy
(ability of species to withstand
catastrophic events) by evaluating the
number and distribution of resilient
populations throughout the species’
range.
Current Condition of Frecklebelly
Madtom
The historical range for the
frecklebelly madtom includes two large
river basins that enter into the Gulf of
Mexico: The Pearl River Basin and the
Mobile River Basin. The Pearl River
Basin is in eastern Louisiana and
southern Mississippi (identified as Pearl
River (A) representation unit in the
SSA). The Mobile River Basin consists
of the Tombigbee River in eastern
Mississippi and western Alabama
(Upper Tombigbee (B) representation
unit); the upper Alabama (Alabama

River (D) representation unit) and
Cahaba Rivers (Cahaba River (E)
representation unit) in central Alabama;
the Etowah River (part of the Upper
Coosa River (F) representation unit) in
northern Georgia; and the Conasauga
River (part of the Upper Coosa River (F)
representation unit) in northern Georgia
and southeastern Tennessee.
Historically, the species was likely more
widespread in the Mobile Bay drainage
but was extirpated from large river
habitats after the creation of numerous
impoundments, and thus, the species’
current representation has been reduced
from historical levels. Currently, the
species is known to be extant in four
(Pearl River (A), Upper Tombigbee River
(B), Cahaba River (E), and Upper Coosa
River (F)) of the six representation units.
Within the Pearl River (A)
representation unit, there are two
resilience units (Bogue Chitto River (A1)
and Pearl River (A2)) assessed to have
high resiliency to stochastic events
based on stable populations and
complex range geometry with 15
occupied streams in the Pearl River. In
addition, recent surveys (2009–2019)
observed frecklebelly madtom at 83
percent of known historical sites (i.e.,
any site in which the species was
previously observed) (Wagner et al.
2018, entire; Service 2020, p. 59).
Within the Upper Tombigbee River
(B) representation unit, there is one
resilience unit (Buttahatchee River (B4))
assessed to have high resiliency, three
(East Fork Tombigbee River (B1), Sipsey
River (B2), and Luxapallila Creek (B3))
have moderate resiliency, and two are
likely extirpated (Upper Tombigbee
River (B6) and Bull Mountain Creek
(B5)). The Buttahatchee River (B4) unit
has been identified as a stronghold of
the species where it has consistently
been collected in higher numbers
(Shepard et al. 1997, p. 23, Bennett et
al. 2008, p. 470). For the East Fork of the
Tombigbee River (B1) unit, the species
has recent (2009–2019) collections of
more than 100 individuals per survey
event (i.e., occurrence) of frecklebelly
madtom. However, there has been a loss
of habitat, altered water quality, and
loss of connectivity in the East Fork
with numerous structures installed for
the Tennessee-Tombigbee Waterway
(Tenn-Tom Waterway) (Millican et al.
2006, p. 3–4). Within the Sipsey River
(B2) unit, experts have indicated that
the habitat is excellent with few threats
and the populations appear stable, albeit
few records for them exist (Shepard et
al. 1997, pp. 9, 23). Frecklebelly
madtom persists in Luxapallila Creek
(B3) with stable populations and recent
(2009–2019) collections of almost 100
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
individuals per survey event (i.e.,
occurrence).
Historically, the mainstem of the
upper Tombigbee River (mainstem, B6)
unit was considered to support robust
populations of the frecklebelly madtom
with some sites producing single
collections of over 300 individuals
during the assessment period from
1950–1987 (Bennet et al. 2008, p. 466;
Service 2020, p. 49). However, the
construction of the Tenn-Tom
Waterway, a canal system that connects
the Tombigbee River to the Tennessee
River for commercial navigation,
eliminated the suitable gravel-cobble
habitat for the species (Shepard et al.
1997, p. 4). Despite fish assemblage
surveys undertaken since the
construction of the waterway (e.g.,
Millican et al. 2006, entire),
observations of the species cease in the
mainstem of the upper Tombigbee River
(B6) after 1980 (Bennett et al. 2008, p.
466), thus supporting the species’ likely
extirpation from this formerly occupied
habitat. The frecklebelly madtom has
not been observed in the Bull Mountain
Creek (B5) unit since 1978–1987
assessment period; this unit was also
drastically altered by the construction of
the Tenn-Tom Waterway and is
currently bisected by the canal system
(Millican et al. 2006, p. 3). The habitat
lost from this major construction and
engineering activity has likely caused
the extirpation of the frecklebelly
madtom in the upper Tombigbee River
(B6) (Millican et al. 2006 p. 84; Shepard
2004, p. 221; Bennett et al. 2008, p. 467)
and Bull Mountain Creek (B5) (Shepard
2004, p. 221) resilience units.
Within the Lower Tombigbee/
Alabama Rivers (C) representation unit,
there are two resilience units (Lower
Tombigbee River (C1) and Lower
Alabama River (C2)) assessed to have
unknown resiliency. There are no
traditional occurrence data of this
species for either resilience unit;
however, eDNA of frecklebelly madtom
was found in both units (Janosik and
Whittaker 2018, p. 7).
Within the Alabama River (D)
representation unit, there is one
resilience unit (Alabama River (D1))
assessed to be likely extirpated.
Following the construction of the
Miller’s Ferry Lock and Dam and
Claiborne Dam in the late 1960s, there
have been no occurrences of this species
in the Alabama River (D1) unit, despite
efforts to locate the species (Shepherd et
al. 1997, p. 18).
Within the Cahaba River (E)
representation unit, one resilience unit
(Cahaba River (E1)) was estimated to
have moderate resiliency to stochastic
events. The Cahaba River system is
PO 00000
Frm 00008
Fmt 4701
Sfmt 4702
believed to be a stronghold for the
species (Neely 2018, p. 11) where it
appears to be abundant (Bennet et al.
2008, p. 467). The Alabama River-Big
Swamp Creek (E2) resilience unit is
likely extirpated; no observations have
been made of this species in the unit
since the late 1960s after the
construction of Miller’s Ferry Lock and
Dam and Claiborne Dam despite efforts
to locate the species (Shepherd et al.
1997, p. 18; Bennet et al. 2008, p. 464).
Within the Coosa River (F)
representation unit, one resilience unit
(Conasauga River (F1)) was estimated to
have low resiliency, one with moderate
resiliency (Etowah River (F3)), and one
with unknown resiliency (Coosawattee
River (F2)). In the Conasauga River (F1),
fish assemblage and abundance from the
1990s–2000s documented declines in
several fish species, including the
frecklebelly madtom, and after 2000, the
frecklebelly madtom was no longer
detected in fish surveys (Freeman et al.
2003, pp. 569–570; Bennett et al. 2008
p. 466). These surveys indicate a
reduced resiliency in the Conasauga
River (F1), because the best available
occurrence data present a transition
from a measurable population of the
frecklebelly madtom to an
unmeasurable one. Despite a 20-year
lapse since the last observation of the
frecklebelly madtom, the current
presence of the species in the Conasauga
River (F1) is supported by eDNA that
was collected in 2017 and 2018
(Freeman and Bumper 2018, entire), as
described above. Furthermore, the
Conasauga River (F1) has not
experienced the same type of habitat
modifications as other rivers that have
caused localized extirpation of the
species (dams, impoundments, and
channelization), and the species has
been observed more recently in river
surveys than in river sections where it
is considered extirpated. Therefore, we
determined that the species remains
present in the Conasauga River but with
low resiliency to stochastic events, as
estimated from the occurrence data.
Within the Etowah River (F3),
frecklebelly madtom populations appear
stable, albeit at lower levels of
abundance, as the patterns of
occurrence in the most recent time
period is similar to time periods prior to
1998. There are no historical occurrence
data or direct observations of the species
from the Coosawattee River (F2)
resilience unit. Environmental DNA for
the frecklebelly madtom was found in
portions of this unit (Freeman and
Bumpers 2018, p. 9); therefore, we
assessed this unit as having an
unknown resiliency.
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
Overall, the frecklebelly madtom was
assessed to have three units with high
resiliency, five units with moderate
resiliency, one unit with low resiliency,
three units with unknown resiliency
(eDNA only), and four units that are
likely extirpated.
For species’ redundancy, we assessed
the number and distribution of resilient
populations across the frecklebelly
madtom’s range, and we considered
catastrophic events that could impact
frecklebelly madtom. Catastrophic
events may include chemical spills,
large and rapid changes in upstream
land use that alter stream characteristics
and water quality downstream, new
impoundments or other engineered
devices that alter natural hydrological
processes, and potential effects of
climate change, such as drought and
increases in occurrence of flash flooding
events. Given the broad distribution of
extant resilience units and several units
assessed as having moderate to high
resiliency, it is unlikely that a
catastrophic event would impact the
entire species’ range. Therefore, the
frecklebelly madtom exhibits a
moderate to high degree of redundancy
and that level of redundancy has
remained relatively stable over time.
Risk Factors for Frecklebelly Madtom
We reviewed the potential risk factors
(see discussion of section 4(a)(1) of the
Act, above) that are affecting the
frecklebelly madtom now and are
expected to affect it into the future. We
have determined that habitat
destruction and degradation caused by
agriculture and development resulting
in poor water quality (Factor A) pose the
largest risk to the current and future
viability of the frecklebelly madtom.
Other potential stressors to the species
are habitat degradation resulting from
channelization, dams, and
impoundments (Factor A) and climate
change (Factor E). We find the species
does not face significant threats from
overutilization (Factor B), disease or
predation (Factor C), or invasive species
(Factor E). We also reviewed the
conservation efforts being undertaken
for the habitat in which the frecklebelly
madtom occurs. A brief summary of
relevant stressors is presented below; for
a full description, refer to chapter 4 of
the SSA report (Service 2020, entire).
Water Quality
The frecklebelly madtom, like other
benthic aquatic species, is sensitive to
poor water quality (Warren et al. 1997,
p. 125) and needs clean, flowing water
to survive; thus water quality
degradation is considered a threat to the
species. Changes in water chemistry and
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
flow patterns, resulting in a decrease in
water quality and quantity have
detrimental effects on madtoms, because
they can render aquatic habitat
unsuitable for occupancy.
Inputs of point (discharge from
particular pipes) and nonpoint (diffuse
land surface runoff) source pollution
across the frecklebelly madtom range
are numerous and widespread. Point
source pollution can be generated from
inadequately treated effluent from
industrial plants, sanitary landfills,
sewage treatment plants, active surface
mining, drain fields from individual
private homes, and others (Service 2000,
pp. 14–15). Nonpoint pollution
originates from agricultural activities,
poultry and cattle feedlots, abandoned
mine runoff, construction, failing septic
tanks, and contaminated runoff from
urban areas (Deutsch et al. 1990, entire;
Service 2000, pp. 14–15). These sources
contribute pollution to streams via
sediments, heavy metals, fertilizers,
herbicides, pesticides, animal wastes,
septic tank and gray water leakage, and
oils and greases. Water quality and
native aquatic fauna decline as a result
of this pollution through nitrification,
decreases in dissolved oxygen
concentration, increases in acidity and
conductivity, or direct introduction of
toxicants. These alterations likely have
direct (e.g., decreased survival and/or
reproduction) and indirect (e.g., loss,
degradation, and fragmentation of
habitat) effects. For some aquatic
species, including the frecklebelly
madtom, submergent vegetation
provides critical spawning habitat for
adults, refugia from predators, and
habitat for prey of all life stages (Jude
and Pappas 1992, pp. 666–667, Freeman
et al. 2003, p. 54). Degraded water
quality and the high algal biomass that
result from pollutant inputs cause loss
of these critical submergent plant
species (Chow–Fraser et al.1998, pp.
38–39) that are vital habitat for the
frecklebelly madtom.
The frecklebelly madtom is intolerant
to sedimentation (Shepard 2004, p. 221;
MMNS 2014, p. 35), and sedimentation
is a concern throughout the species’
range. Researchers have documented a
negative relationship between
occurrence of the frecklebelly madtom
and human-induced increases of
sediment within the upper Tombigbee
River (mainstem), Alabama River,
Cahaba River, Luxapallila Creek,
Etowah River, and Conasauga River
(Burkhead et al. 1997, pp. 406–413;
Shepherd et al. 1997, pp. 15–19;
Freeman et al. 2002, pp. 18–19;
Freemen et al. 2017, pp. 429–430).
Human-induced increases in sediment
are likely a factor in local declines of the
PO 00000
Frm 00009
Fmt 4701
Sfmt 4702
74057
species. In addition, the frecklebelly
madtom’s habitat requirements make it
vulnerable to activities that disturb
substrate integrity. The species is
restricted to habitat with pea-sized
gravel, cobble, or slab-rock substrates
not embedded in large amounts of silt
(Bennett et al. 2008, p. 467; Bennett and
Kuhajda. 2010, p. 510), although it has
also been found to occupy some stable
streams with a sandy yet stable
substrate. Degradation from
sedimentation, physical habitat
disturbance, and contaminants threaten
the habitat and water quality on which
the frecklebelly madtom depends.
Sedimentation from an array of land
uses (e.g., urbanization, agriculture,
channel maintenance activities) could
negatively affect the species by reducing
growth rates, disease tolerance, and gill
function; reducing spawning habitat,
reproductive success, and egg (embryo),
larva, and juvenile development;
reducing food availability through
reductions in prey; reducing foraging
efficiency; and reducing shelter.
A wide range of current activities and
land uses, including agricultural
practices, construction, stormwater
runoff, unpaved roads, poor forest
management, utility crossings, and
mining, can lead to excessive
sedimentation within streams. Fine
sediments not only smother streams
during current ongoing activities,
historical land use practices may have
substantially altered hydrological and
geological processes such that
sediments continue to be input into
streams for several decades after those
activities cease (Harding et al. 1998, p.
14846).
Water quality for frecklebelly madtom
is particularly impacted by three
processes: Channel modification (i.e.,
dredging and channelization),
agriculture, and development, which are
further discussed below.
Channel Modification
Dredging and channelization have led
to loss of aquatic habitat in the
Southeast (Neves et al. 1997, p. 71).
Dredging and channelization projects
are extensive throughout the region for
flood control, navigation, sand and
gravel mining, and conversion of
wetlands into croplands (Neves et al.
1997, p. 71; Herrig and Shute 2002, pp.
542–543). Dredging and channelization
modify and destroy habitat for aquatic
species by destabilizing the substrate,
increasing erosion and siltation,
removing woody debris, decreasing
habitat heterogeneity, and stirring up
contaminants that settle onto the
substrate (Williams et al. 1993, pp. 7–8;
Buckner et al. 2002, entire; Bennett et
E:\FR\FM\19NOP2.SGM
19NOP2
74058
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
al. 2008, pp. 467–468). Channelization
can also lead to head cutting (an
erosional process in a stream channel
with a vertical cut or drop that migrates
upstream over time), which causes
further erosion and sedimentation
(Hartfield 1993, pp. 131–141). Dredging
can involve snagging (the removal of
woody debris from the channel), which
not only contributes to destabilization of
the channel but also removes the woody
debris that provides important cover
and nest locations for many fish species,
including the frecklebelly madtom
(Bennett et al. 2008, pp. 467–468).
The frecklebelly madtom was
eliminated from much of the mainstem
of the Tombigbee River after the
construction of the Tenn-Tom
Waterway. Tributaries to the upper
Tombigbee River have also been affected
by channel modification of the TennTom Waterway due to head cutting and
other geomorphic and flow
modifications (Raborn and Schramm
2003, pp. 289–301; Roberts et al. 2007,
pp. 250–256; Tipton et al. 2004, pp. 49–
61), and fewer tributaries currently
maintain the habitat needed by the
frecklebelly madtom in this system
(Millican et al. 2006, p. 84; Shepard
2004, pp. 220–222; Shepard et al. 1997,
pp. 3–4). Similarly, channel
geomorphology and substrate are likely
being affected by head cutting due to
impoundment of the Alabama River
(Bennett et al. 2008, p. 468).
Alternatively, frecklebelly madtom
abundances have remained stable in the
Cahaba River throughout the
modification periods that affected
surrounding drainages. The Cahaba
River, Conasauga River, and some
tributaries to the upper Tombigbee River
are the only remaining waters within
the range of the frecklebelly madtom
that have escaped large-scale human
modification through damming or
channelization (Bennet et al. 2008, p.
468).
Agriculture
Agricultural practices such as
traditional farming, feedlot operations,
and associated land use practices can
contribute pollutants to rivers. These
practices can also degrade habitat by
eroding stream banks, which results in
alterations to stream hydrology and
geomorphology. Nutrients, bacteria,
pesticides, and other organic
compounds are generally found in
higher concentrations in agricultural
areas rather than forested areas.
Contaminants associated with
agriculture (e.g., fertilizers, pesticides,
herbicides, and animal waste) can
degrade water quality and negatively
impact instream habitats by causing
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
oxygen deficiencies, excess
nutrification, and excessive algal
growths, which can have a direct impact
on fish community composition
(Petersen et al. 1999, p. 6).
Areas within the current range of the
frecklebelly madtom, which are
predominantly agricultural, are
impacted by nonpoint source sediment
and agrochemical discharges altering
the physical and chemical
characteristics of its habitat, thus
potentially impeding its ability to feed,
seek shelter from predators, and
successfully reproduce. A negative
relationship between the species and
nonpoint source stressors attributed to
agriculture has been described
particularly within the Conasauga River
(Freeman et al. 2017, pp. 429–430).
Over the past two decades, an increase
in the use of agricultural chemicals and
practices, such as use of glyphosatebased herbicides for weed control and
land dispersion of animal waste for soil
amendment, has corresponded with
marked declines in populations of fish
and mussel species in the Upper
Conasauga River watershed in Georgia
and Tennessee (Freeman et al. 2017, p.
429). Nutrient enrichment of streams
was found to be widespread with high
levels of nitrate and phosphorus
(reported at over 5 milligrams per liter
and over 300 micrograms per liter,
respectively, within the Conasauga
River) likely associated with
eutrophication, and hormone
concentrations in sediments were often
above those shown to cause endocrine
disruption in fish, which was possibly
related to the widespread application of
poultry litter and manure (Lasier et al.
2016, entire). Estrogens, a hormone and
type of endocrine disruptor that can be
found in poultry litter, also have been
identified as a threat to aquatic fauna in
the Conasauga River system (Jacobs
2015, entire). Increased levels of
estrogens can lead to decreases in
spawning success and potentially
population collapse within short
timeframes (Kidd et al. 2007, p. 8899).
Aquatic species declines observed in the
Conasauga watershed may be at least
partially due to hormones, as well as
excess nutrients, herbicides, and
surfactants (Freeman et al. 2017, p. 429).
The amount (acreage) of agricultural
land is declining across the eastern
United States with a net loss of 6.5
percent between 1973 and 2000 (Sayler
et al. 2016, p. 12). As discussed below
under Future Scenarios, within the
watersheds in which frecklebelly
madtom occurs, the declining trend of
agricultural land is consistent with
broader trends in the eastern United
States showing agricultural land
PO 00000
Frm 00010
Fmt 4701
Sfmt 4702
declines with time (Sayler et al. 2016, p.
12). These agricultural lands are mostly
being converted to developed and
forested lands (Sayler et al. 2016, p. 12).
Despite the declining trend, agricultural
practices leading to poor water quality
conditions currently influence and will
continue to influence the viability of
frecklebelly madtom across its range.
Development
Development is a significant source of
water quality degradation that can
reduce the survival of aquatic
organisms, including the frecklebelly
madtom. Urban development can stress
aquatic systems in a variety of ways,
including increasing the frequency and
magnitude of high flows in streams;
increasing sedimentation and nutrient
loads; increasing contaminants and
toxicity; decreasing the diversity of fish,
aquatic insects, plants, and amphibians;
and changing stream morphology and
water chemistry (Coles et al. 2012,
entire; CWP 2003; entire). Sources and
risks of an acute or catastrophic
contamination event, such as a leak
from an underground storage tank or a
hazardous materials spill on a highway,
increase as urbanization increases.
Urbanization has also been shown to
impair stream quality by impacting
riparian health (Diamond et al. 2002, p.
1150). Riparian impairment resulting
from urbanization or agricultural land
use can amplify negative effects of
nonpoint source pollution within the
watershed as well as impact stream
quality independent of land use within
the watershed. Impacts from impervious
cover can be mitigated through riparian
forest cover and good riparian health
(Roy et al. 2005, p. 2318; Walsh et al.
2007, entire); however, the benefit of the
riparian cover diminishes when
impervious cover (i.e., urban cover)
exceeds approximately 10 percent
within the watershed (Booth and
Jackson 1997, p. 1084; Goetz et al. 2003,
p. 205).
Currently, larger population centers,
such as the cities of Atlanta, Georgia,
Jackson, Mississippi, and Birmingham,
Alabama, contribute substantial runoff
to the watersheds occupied by the
frecklebelly madtom. In the future,
urbanization is predicted to increase in
several areas across the range of the
frecklebelly madtom (see below under
Future Scenarios). All watersheds, but
especially the Etowah River watershed,
upstream of Lake Allatoona in Georgia
are expected to experience additional
urbanization (Albanese et al. 2018, p.
39). Conservation concerns in the
Etowah River watershed have focused
on potential effects of this predicted
urban growth on imperiled fishes
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
(Burkhead et al. 1997, pp. 959–968;
Wenger et al. 2010, pp. 11–21), and
previous analyses show negative
correlations between occurrence of
native fishes and increases in
impervious cover associated with urban
development (Wenger et al. 2008, p.
1260). In the Etowah Basin in Georgia,
models indicated that urbanization
lowered fish species richness and
density and led to predictable changes
in species composition. Darters, sculpin,
minnows, and endemic species declined
along the urban gradient, whereas
sunfishes persisted and became the
dominant group (Walters et al. 2005, pp.
10–11). In the future, we anticipate
increased development to amplify as a
population-level factor influencing the
viability of frecklebelly madtom.
Impoundments
Impoundment of rivers is a stressor to
aquatic species in the southeast (Benz
and Collins 1997, pp. 22–23, 63, 91,
205, 273, 291, 397, 399, 401–406, 446;
Buckner et al. 2002, pp. 10–11). Dams
modify habitat conditions and aquatic
communities both upstream and
downstream of an impoundment
(Winston et al. 1991, pp. 103–104;
Mulholland and Lenat 1992, pp. 193–
231; Soballe et al. 1992, pp. 421–474).
Upstream of dams, habitat is flooded
and in-channel conditions change from
flowing to still water, with increased
depth, decreased levels of dissolved
oxygen, and increased sedimentation.
Sedimentation alters substrate
conditions by filling in interstitial
spaces between rocks, which provide
habitat for many species (Neves et al.
1997, pp. 63–64), including the
frecklebelly madtom. Downstream of
dams, flow regime fluctuates with
resulting fluctuations in water
temperature and dissolved oxygen
levels, the substrate is scoured, and
downstream tributaries are eroded
(Neves et al. 1997, pp. 63–64; Schuster
1997, p. 273; Buckner et al. 2002, p. 11).
Negative ‘‘tailwater’’ effects on habitat
can extend many kilometers
downstream (Neves et al. 1997, p. 63).
Dams fragment habitat for aquatic
species by blocking corridors for
migration and dispersal, resulting in
population isolation and heightened
susceptibility to extinction (Neves et al.
1997, p. 63). Dams also preclude the
ability of aquatic organisms to escape
from polluted waters and accidental
spills (Buckner et al. 2002, p. 10).
Damming of streams and springs is
also extensive throughout the Southeast
and occurs within the large river
habitats of the frecklebelly madtom
(Etnier 1997, pp. 88–89; Morse et al.
1997, pp. 22–23; Shute et al. 1997, pp.
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
458–459, Bennett et al. 2008, p. 467).
Many streams have both small ponds in
their headwaters and large reservoirs in
their lower reaches (Morse et al. 1997,
p. 23). Small streams on private lands
are regularly dammed to create ponds
for cattle, irrigation, recreation, and
fishing, with significant ecological
effects due to the sheer abundance of
these structures (Morse et al. 1997, pp.
22–23). In addition, small headwater
streams are increasingly being dammed
in the Southeast to supply water for
municipalities (Buckner et al. 2002, p.
11).
Dams are known to have caused the
extirpation and extinction of many
southeastern species, and existing and
proposed dams pose an ongoing threat
to many aquatic species (Folkerts 1997,
p. 11; Neves et al. 1997, p. 63; Riciarddi
and Rasmussen 1999, p. 1222; Service
2000, p. 15; Buckner et al. 2002, p. 11,
Olden 2016, pp. 112–122), including the
frecklebelly madtom. The construction
of 10 lock and dam structures on the
Tenn-Tom Waterway, which artificially
connects the Tennessee River to the
Gulf of Mexico, led to the extirpation of
many species, including the frecklebelly
madtom, from the main river channel
(Bennett et al. 2008, p. 467). The
frecklebelly madtom is considered
extirpated from the Alabama River,
likely due to the construction of three
dams in the late 1960s and early 1970s
(Bennett et al. 2008, p. 467). In addition,
the construction of one dam on the
Etowah River may have affected the
frecklebelly madtom, since the species
is dependent on large-river gravel shoal
substrate (Bennett et al. 2008, p. 470).
As discussed above in Current
Condition of Frecklebelly Madtom, four
resilience units are likely extirpated as
a result of dam construction and large
scale river modifications.
Climate Change
In the southeastern United States,
several climate change models have
projected more frequent drought, more
extreme heat (resulting in increases in
air and water temperatures), increased
heavy precipitation events (e.g.,
flooding), more intense storms (e.g.,
frequency of major hurricanes
increases), and rising sea level and
accompanying storm surge (IPCC 2013,
entire). When taking into account future
climate projections for temperature and
precipitation where the frecklebelly
madtom occurs, warming is expected to
be greatest in the summer, which is
predicted to increase drought frequency.
Nevertheless, annual mean precipitation
is expected to increase slightly, leading
to a slight increase in flooding events
(Alder and Hostetler 2013, unpaginated;
PO 00000
Frm 00011
Fmt 4701
Sfmt 4702
74059
IPCC 2013, entire; USGS 2020,
unpaginated). Changes in climate may
affect ecosystem processes and
communities by altering the abiotic
conditions experienced by biotic
assemblages, resulting in potential
effects on community composition and
individual species interactions (DeWan
et al. 2010, p. 7).
The frequency, duration, and
intensity of droughts are likely to
increase in the southeastern United
States as a result of global climate
change (Konrad et al. 2013, p. 34),
which could negatively affect stream
flows in the region. Stream flow is
strongly correlated with important
physical and chemical parameters that
limit the distribution and abundance of
riverine species (Power et al. 1995,
entire; Resh et al. 1988, pp. 438–439)
and regulates the ecological integrity of
flowing water systems (Poff et al. 1997,
p. 770).
To understand how climate change is
projected to affect where frecklebelly
madtom occurs, we used the National
Climate Change Viewer (NCCV), a
climate-visualization tool developed by
the U.S. Geological Survey (USGS), to
generate future climate projections
across the range of the species. The
NCCV is a web-based tool for
visualizing and assessing projected
changes in climate and water balance at
watershed, State, and county scales
(USGS 2020, unpaginated). To evaluate
the effects of climate change in the
future, we used projections from
Representative Concentration Pathway
(RCP) 4.5 and RCP 8.5 to characterize
projected future changes in climate and
water resources, averaged for the SouthAtlantic Gulf Region encompassing the
range of the frecklebelly madtom
(Service 2020, pp. 27–31). The
projections estimate changes in mean
annual values for maximum air
temperature, minimum air temperature,
monthly precipitation, and monthly
runoff, among other factors, from
historical (1981–2010) to future (2050–
2074) time series.
Within the range of the frecklebelly
madtom, the NCCV projects that, under
the RCP 4.5 scenario, maximum air
temperature will increase by 1.9 degrees
Celsius (°C) (3.4 degrees Fahrenheit
(°F)), minimum air temperature will
increase by 1.8 °C (3.2 °F), precipitation
will increase by 5.36 millimeters (0.2
inches) per month, and runoff will
remain the same in the 2050–2074 time
period (USGS 2020, unpaginated).
Under the more extreme RCP 8.5
scenario, the NCCV projects that
maximum air temperature will increase
by 2.8 degrees Celsius (°C) (5 degrees
Fahrenheit (°F)), minimum air
E:\FR\FM\19NOP2.SGM
19NOP2
74060
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
temperature will increase by 2.7 °C
(4.9 °F), precipitation will increase by
5.36 millimeter (0.2 inches) per month,
and runoff will remain the same in the
2050–2074 time period (USGS 2020,
unpaginated). These estimates indicate
that, despite projected minimal
increases in annual precipitation,
anticipated increases in maximum and
minimum air temperatures will likely
offset those gains. Based on these
projections, the frecklebelly madtom
will on average be exposed to increased
air temperatures across its range, despite
limited increases in precipitation;
however, these projections are not a
one-to-one air to stream water
temperature comparison.
Despite the recognition of climate
effects on ecosystem processes, there is
uncertainty within each model and
model ensembles about what the exact
climate future will be, and there is
uncertainty in how the ecosystems and
species will respond. Although there are
several potential risks associated with
long-term climate change as described
above, there is uncertainty regarding
how the frecklebelly madtom will
respond to these risks. The species
occupies some tributaries throughout its
range, but the frecklebelly madtom has
a preference for habitat in larger rivers
and this may provide a buffer to changes
induced by climate change, particularly
from issues associated with drought.
Therefore, we do not consider climate
change to be a primary risk factor for the
species at this time.
Conservation Efforts
The frecklebelly madtom is
recognized as a species of concern in all
States where it occurs and is protected
by State statute in four States where it
occurs. This species is listed as
endangered by the State of Georgia
(GADNR 2015, p. 74), endangered by the
State of Mississippi (Mississippi
Museum of Natural Science 2015, p. 36),
and threatened by the State of
Tennessee (TWRA 2015, Appendix C).
In Alabama, the frecklebelly madtom is
designated as a protected nongame
species under Alabama Code 220–2–.92.
In general, the protections accorded to
the frecklebelly madtom by Mississippi,
Alabama, Georgia, and Tennessee
prohibit direct exploitation of the
species without a permit within those
States.
Beginning in 2017, the Private John
Allen National Fish Hatchery partnered
with the Mississippi Department of
Wildlife Fisheries and Parks to collect
individuals of the frecklebelly madtom
within that State to study marking
techniques, establish captive husbandry
methods, and conduct life-history
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
studies. This effort has led to successful
propagation of the species, documented
important components of the species’
life history, and collected data that can
be used to develop long-term, captivepropagation efforts, although no
individuals have been released.
Throughout the range of the species,
portions of occupied rivers and
surrounding lands are owned and
managed by State and Federal entities
that prioritize conservation as a
management objective. Generally, these
entities help to maintain the natural
ecosystem functioning of a river by
managing terrestrial areas in a more
natural state and limiting disturbance
adjacent to rivers. However, properties
managed by the Service, U.S. Forest
Service, and the Dawson Forest Wildlife
Management Area (WMA) managed by
the Georgia Department of Natural
Resources, are known to specifically
consider and manage for the
conservation of aquatic species and
their habitats. It is expected that the
frecklebelly madtom will be positively
affected by management on these lands.
These conservation lands and the
adjacent rivers occupied by the
frecklebelly madtom include: Portions
of the Bogue Chitto and Pearl Rivers
within the Bogue Chitto National
Wildlife Refuge (NWR, Service) in
Louisiana; portions of the Bogue Chitto
River within Bogue Chitto State Park
(Louisiana Department of Culture,
Recreation, and Tourism) in Louisiana;
portions of the Pearl River within the
Pearl River WMA (Louisiana
Department of Wildlife and Fisheries) in
Louisiana; portions of the Cahaba River
within the Cahaba NWR (Service) in
Alabama; portions of the Conasauga
River within the Cherokee National
Forest (U.S. Department of Agriculture
(USDA) U.S. Forest Service) in Georgia;
and portions of the Etowah River within
the Dawson Forest WMA (Georgia
Department of Natural Resources) in
Georgia. In addition, the Etowah River
catchment area upstream of habitat
occupied by the frecklebelly madtom
and managed by the ChattahoocheeOconee National Forest (USDA U.S.
Forest Service) is expected to benefit the
species by providing good water quality
to lower river reaches.
The Natural Resources Conservation
Service (NRCS), USDA, designated the
Conasauga River as a Working Lands for
Wildlife (WLFW) landscape in 2017
(USDA 2020, unpaginated) and will
provide additional funds and humanpower to improve water quality and
aquatic habitat in the watershed. The
project will provide technical and
financial assistance to help landowners
improve water quality and help

producers plan and implement a variety
of conservation activities or practices
that benefit aquatic species. The
frecklebelly madtom will likely benefit
from water quality improvements in
portions of the Conasauga River that are
affected by agricultural practices
implemented through the WLFW
project.
Synergistic and Cumulative Effects
We note that, by using the SSA
framework to guide our analysis of the
scientific information documented in
the SSA report, we have not only
analyzed individual effects on the
species, but we have also analyzed their
potential cumulative effects. We
incorporate the cumulative effects into
our SSA analysis when we characterize
the current and future condition of the
species. Our assessment of the current
and future conditions encompasses and
incorporates the threats individually
and primary threats cumulatively. Our
current and future condition (see below)
assessment is iterative, because it
accumulates and evaluates the effects of
all the 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.
In addition to impacting frecklebelly
madtom individually, it is possible that
several of the above summarized risk
factors are acting synergistically or
cumulatively on the species. The
combined impact of multiple stressors is
likely more harmful than a single
stressor acting alone. The dual stressors
of climate change and direct human
impact have the potential to affect
aquatic ecosystems by altering stream
flows and nutrient cycles, eliminating
habitats, and changing community
structure (Moore et al. 1997, p. 942).
Increased water temperatures and a
reduction in stream flow are the climate
change effects that are most likely to
affect stream communities (Poff 1997,
entire), and each of these variables is
strongly influenced by land use
patterns. For example, in agricultural
areas, lower precipitation may trigger
increased irrigation resulting in reduced
stream flow (Backlund et al. 2008, pp.
42–43). In forested areas, trees influence
instream temperatures through the
direct effects of shading. Reductions in
temperature by vegetative cover may be
particularly important in low-order
streams, where canopy vegetation
significantly reduces the magnitude and
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
variation of the stream temperature
compared with that of clear-cut areas
(Ringler and Hall, 1975, pp. 111–121).
Future Scenarios
To evaluate the future viability of the
frecklebelly madtom and address
uncertainty associated with the degree
and extent of potential future stressors
and their impacts to the madtom, we
analyzed three future scenarios and
assessed the resiliency, representation,
and redundancy of the madtom for each
scenario. We devised these scenarios by
identifying information on the following
primary threats that are anticipated to
affect the frecklebelly madtom in the
future: Agriculture and developed land
use. We considered projected changes in
agricultural and developed land uses in
assessing future resiliency of each
resilience unit for frecklebelly madtom.
We assessed these land uses to
understand the future impacts to habitat
degradation and destruction resulting
from poor water quality, a primary
threat to frecklebelly madtom. The three
scenarios capture the range of variability
in the changing human population
footprint on the landscape and how
frecklebelly madtom populations will
respond to these changing conditions.
All three scenarios were projected out to
the year 2050 (i.e., 30 years), because we
were reasonably certain we could
forecast patterns in land-use change and
understand how these land uses will
interact with the frecklebelly madtom
and its habitat over this time period
given the species’ life span.
In our development of future
scenarios, we used projected trends in
land use change from two models, the
National Land Cover Database (NLCD)
and the Slope, Land use, Excluded,
Urban, Transportation and Hillshade
(SLEUTH) model (Jantz et al. 2010,
entire). Future projections for
agricultural land use were developed
from NLCD data by calculating a 15-year
trend in agricultural land use change
between 2001 and 2016 for each
resilience unit and converting that to an
annual rate of agricultural land use
change for each resilience unit. We used
the annual rate of agricultural land use
change to project changes to 30 years
from the present. The annual rate of
agricultural land use change was held
constant for each resilience unit across
all scenarios; however, the rate of
change in agricultural area varied
among the resilience units we evaluated
in our analysis. With the exception of
the Alabama River resilience unit,
which has an increase in the amount of
agricultural land use over time, we
found an overall decline in the amount
of land used for agriculture. This result
is consistent with broader trends that
show the amount of agricultural land is
declining with time in the eastern
United States (Sayler et al. 2016, p. 12).
For our future developed land use
projections, we used the SLEUTH
datasets from the year 2050 (closest to
30 years in the future) and examined
development across resilience units. We
then developed three scenarios that
varied development probabilities: (1)
Low development, (2) moderate
74061
development, and (3) high development.
For the low development scenario, we
considered all areas predicted to be
developed at a greater than 90 percent
probability (i.e., only including areas
that are almost certain to be developed);
the moderate development scenario
considered all areas to be developed at
a greater than 50 percent probability;
and the high development scenario
considered all areas to be developed at
a greater than 10 percent probability
(i.e., including the majority of areas with
any potential to be developed). The
results of the future projections for
agriculture and developed land use
were used to estimate a composite land
use score, and then using a rule set, we
categorized future resiliency into high,
moderate, low, unknown, or likely
extirpated conditions.
In the low development scenario, the
frecklebelly madtom was projected to
have one unit with high resiliency,
seven units with moderate resiliency,
one unit with low resiliency, and four
units that are likely extirpated (see table
2, below). In terms of projected change
from current condition, the
Buttahatchee River (B4) and Pearl River
(A2) resilience units are projected to
decrease in resiliency from high to
moderate. The Etowah River (F3)
resilience unit is projected to become
more developed, although the percent of
developed land does not reach a point
where a change in resiliency is
anticipated. All other units are projected
to retain their current resiliency under
the low development scenario.

determined as unknown since units are known only from eDNA data.
In the moderate development
scenario, the frecklebelly madtom was
projected to have one unit with high
resiliency, six units with moderate
resiliency, two units with low
resiliency, and four units that are likely
extirpated (see table 2, above). In terms
VerDate Sep<11>2014

Jkt 253001
of projected change from current
condition, the Buttahatchee River (B4)
and Pearl River (A2) resilience units are
projected to decrease in resiliency from
high to moderate. The Etowah River (F3)
resilience unit is projected to become
substantially more developed under this

scenario, and, therefore, this unit is
projected to decrease in resiliency from
moderate to low. All other units are
projected to retain their current
resiliency.
In the high development scenario, the
frecklebelly madtom was projected to
E:\FR\FM\19NOP2.SGM
19NOP2
74062
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
have one unit with high resiliency, six
units with moderate resiliency, one unit
with low resiliency, and five units that
are likely extirpated (see table 2, above).
In terms of projected change from
current condition, the Buttahatchee
River (B4) and Pearl River (A2)
resilience units are projected to decrease
in resiliency from high to moderate. The
Etowah River (F3) resilience unit is
projected to become substantially more
developed under this scenario;
therefore, this unit is projected to
decrease in resiliency from moderate to
low. The Conasauga River (F1)
resilience unit is projected to decrease
in resiliency from low to being likely
extirpated as a result of high levels of
both agriculture and developed land
uses. All other units are projected to
retain their current resiliency.
In summary, the resiliency of
frecklebelly madtom resilience units are
projected to remain similar to the
current condition with eight units
having moderate to high resiliency
under the low development scenario
(Service 2020, entire). In the moderate
and high development scenarios, seven
units are projected to have moderate to
high resiliency; two units are projected
to have low resiliency (one unit is low
under current condition) in the
moderate development scenario and one
additional unit is projected to be likely
extirpated (total of five units) in the
high development scenario. The Pearl
River (A) representation unit continues
to be the stronghold for the species, as
resiliency is projected to remain high in
the Bogue Chitto (A1) resilience unit
across all scenarios and the Pearl River
(A2) resilience unit is projected to have
moderate resiliency across all scenarios.
All extant resilience units in the Upper
Tombigbee (B) representation unit are
projected to have moderate resiliency.
The Cahaba River (E1) resilience unit is
projected to maintain moderate
resiliency into the future.
Within the Upper Coosa River (F)
representation unit, the Etowah River
(F3) resilience unit is projected to
become more developed by 2050 under
all scenarios; therefore, in the moderate
and high development scenarios, the
resiliency is projected to decrease from
moderate to low, making the unit more
vulnerable to stochastic events. The
high level of development projected
within riparian areas of the Etowah
River (F3) unit will lead to an increase
in impervious area, which could lead to
further decreases in water quality and
impact the persistence of frecklebelly
madtom. In addition, although the
agricultural trend projects a decrease,
the amount of land in agricultural use
is still projected to remain relatively
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
high. High levels of agriculture and
developed land use projections in this
unit drive the projected low resiliency
by the year 2050. In the Conasauga River
(F1) resilience unit, developed land use
under the high development scenario is
projected to increase, and agriculture
and developed land use are projected to
be at relatively high levels by 2050.
However, the Conasauga River (F1)
resilience unit currently has low
resiliency, and this projected increase in
development is anticipated to further
impact resiliency, resulting in likely
extirpation of the frecklebelly madtom
from this unit.
Finally, the presence of frecklebelly
madtom in the Lower Tombigbee River
(C1), Lower Alabama River (C2), and
Coosawattee River (F2) resilience units
is based on recent positive eDNA
samples, and these units have been
assessed as having an unknown
resiliency. Based on our assessment of
future land use, threat levels from
agriculture and developed land use are
projected to be relatively low in the
Lower Tombigbee (C1) and Lower
Alabama (C2) resilience units. Thus, if
the species is present, there is no
projected increase in threats related to
agriculture or developed land use. In the
Coosawattee River (F2) resilience unit,
there is projected to be relatively high
amounts of agricultural and developed
land. If the species is present there, this
land use pattern could represent a threat
to the individuals occupying the unit.
Future species’ representation is
projected to maintain current levels in
the low development scenario, as the
only projected changes in resiliency are
two units decreasing from high to
moderate resiliency. Under the
moderate and high development
scenarios, the Etowah River (F3) and
Conasauga River (F1) units are projected
to decrease in resiliency. Therefore, the
Upper Coosa River (F) representation
unit is projected to be vulnerable to
extirpation, resulting in a loss of
species’ representation. Given this unit
occurs in a unique physiographic
province and has populations
considered as an evolutionary
significant unit (Neely 2018, pp. 7–10),
the projected loss of this unit would
result in a lower level of representation
for the species.
Species redundancy is projected to
maintain current levels into the future
under the low and moderate
development scenarios, as no additional
resilience units are projected to become
extirpated. In the Upper Coosa River (F)
representation unit, two resilience units
are projected to decrease in resiliency
under the moderate and high scenarios.
Therefore, frecklebelly madtom in these
PO 00000
Frm 00014
Fmt 4701
Sfmt 4702
units are at an increased risk of
extirpation from a catastrophic event.
Given the broad distribution of
moderate to high resilience units, it is
unlikely that a catastrophic event would
impact the entire species’ range.
Determination of Frecklebelly
Madtom’s 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 ‘‘endangered species’’
or ‘‘threatened species.’’ 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 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
We have carefully assessed the best
scientific and commercial information
available regarding the past, present,
and future threats to the frecklebelly
madtom. We considered whether the
frecklebelly madtom is presently in
danger of extinction. Our review of the
best available information indicates
there are 16 resilience units of
frecklebelly madtom within 6
representation units across the known
historical range in Louisiana,
Mississippi, Alabama, Georgia, and
Tennessee. The species was likely more
widespread historically in the Mobile
Bay drainage but was extirpated from
large river habitats after the creation of
numerous impoundments. Currently,
eight resilience units (62 percent) of
frecklebelly madtom have moderate to
high resiliency and are contributing to
the viability of the species; impacts from
habitat destruction and modification do
not appear to be affecting the
frecklebelly madtom at the populationlevel for these resilience units. Five
units (38 percent) have low resiliency or
are likely extirpated due to habitat
destruction and degradation resulting
from channelization, dams, and
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
impoundments, and these units are not
currently contributing to the
frecklebelly madtom’s viability. Three
units have unknown resiliency as these
units have no direct observations of the
species and are known only from eDNA
presence surveys. The species is
currently extant in four of the six
representation units with at least one
resilience unit having moderate to high
resiliency in each of the four
representation units. Given the broad
distribution of the species and eight
units across the range having moderate
to high resiliency, a single catastrophic
event is not likely to impact the species
as a whole. Therefore, the frecklebelly
madtom across its range is currently at
a low risk of extinction from habitat
destruction and other stressors. Thus,
we determine that proposing an
endangered status for the species is not
appropriate.
We forecasted the viability of the
frecklebelly madtom under three
plausible scenarios 30 years into the
future (summarized above in Future
Scenarios). We assessed relevant risk
factors that may be acting on the
frecklebelly madtom in the future and
whether we could make reliable
predictions about these factors and how
they may impact the viability of the
species. We assessed how agriculture
and developed land use is projected to
influence the viability of the
frecklebelly madtom 30 years in the
future (2050). Based on the modeling
and scenarios evaluated, we considered
our ability to make reliable predictions
in the future and the uncertainty in how
and to what degree the species could
respond to those risk factors in this
timeframe. Based on this information,
we determine the appropriate timeframe
for assessing whether this species is
likely to become in danger of extinction
in the foreseeable future is 30 years.
Taking into account the impacts of the
primary factors influencing the species
in the future (habitat destruction and
degradation caused by agriculture and
developed land uses resulting in poor
water quality) and the potential impacts
to the species’ needs, we project the
frecklebelly madtom will continue to
remain resilient to stochastic events
across much of its range. We project that
numerous resilience units will have
moderate to high resiliency over the
next 30 years across the broad
geographic range of the species,
including within the four currently
extant representation units, depending
on scenario. Although two of our
scenarios indicated a decline in the
number of resilience units contributing
to viability of the frecklebelly madtom,
eight units in the low development
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
scenario and seven units in the
moderate and high development
scenarios are projected to remain viable
through 2050. With the projected lower
resiliency from habitat destruction and
degradation within the Upper Coosa
River (F) representation unit, the
species’ representation and redundancy
is lower than current levels. However,
the geographically wide distribution of
resilience and representation units
guards against catastrophic losses
rangewide. We find the multiple
resilience units across multiple
representation units provide resiliency,
representation, and redundancy levels
that are likely sufficient to sustain the
species into the foreseeable future.
Therefore, we find that the risk of
extinction of the frecklebelly madtom is
sufficiently low that it is unlikely to
become endangered within the
foreseeable future, i.e., within the next
30 years.
After evaluating threats to the species
and assessing the cumulative effect of
the threats under the section 4(a)(1)
factors, we conclude that the risk factors
acting on the frecklebelly madtom and
its habitat, either singly or in
combination, are not of sufficient
imminence, scope, or magnitude to rise
to the level to indicate that the species
is in danger of extinction now (an
endangered species), or likely to become
endangered within the foreseeable
future (a threatened species), 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. Having
determined that the frecklebelly
madtom is not in danger of extinction or
likely to become so in the foreseeable
future throughout all of its range, we
now consider whether it may be in
danger of extinction or likely to become
so in the foreseeable future in a
significant portion of its range—that is,
whether there is any portion of the
species’ range for which it is true that
both (1) the portion is significant; and
(2) the species is in danger of extinction
now or likely to become so in the
foreseeable future 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
PO 00000
Frm 00015
Fmt 4701
Sfmt 4702
74063
not need to evaluate the other question
for that portion of the species’ range.
In undertaking this analysis for the
frecklebelly madtom, we chose to
address the status question first—we
consider information pertaining to the
geographic distribution of both the
species and the threats that the species
faces to identify any portions of the
range where the species is endangered
or threatened. We considered whether
any of the threats acting on the
frecklebelly madtom are geographically
concentrated in any portion of the range
at a biologically meaningful scale.
We identified two portions of the
species’ range that may be experiencing
a concentration of threats. First, the
Upper Tombigbee River (B)
representation unit of the frecklebelly
madtom may be experiencing elevated
threats resulting from construction of
the Tenn-Tom Waterway (Factor A). The
construction of the Tenn-Tom Waterway
for commercial navigation eliminated
suitable habitat for the frecklebelly
madtom and has caused the likely
extirpation of two of six resilience units
in the Upper Tombigbee River (B)
representation unit: Upper Tombigbee
River (B6) and Bull Mountain Creek
(B5). We evaluated current status
information and concluded that the
species is effectively extirpated from
these two resilience units. Because we
considered these extirpated units to be
lost historical range, they cannot be
considered as a significant portion of
the range. However, we considered the
effects that the loss of these two units
have on the current and future viability
of the frecklebelly madtom in the Upper
Tombigbee River (B) representation
unit. We then considered the current
status of the remaining four resilience
units in the Upper Tombigbee River
representation unit (B), which currently
have moderate to high resiliency,
including the Buttahatchee River (B4)—
considered a stronghold for the species.
In addition, the East Fork Tombigbee
River (B1) resilience unit has moderate
resiliency with recent collections of
over 100 individuals despite some
habitat impacts from the Tenn-Tom
Waterway. These four units are
projected to have continued moderate
resiliency into the foreseeable future.
Based on these facts, we conclude that
the impacts from the Tenn-Tom
Waterway are not having any
biologically meaningful effect on the
remaining four resilience units in the
Upper Tombigbee River representation
unit (B), which indicates the species
does not have a different status in that
portion of its range. Therefore, even if
the Upper Tombigbee River (B)
representation unit was found to
E:\FR\FM\19NOP2.SGM
19NOP2
74064
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
comprise a significant portion of the
frecklebelly madtom’s range, we
conclude that the species is not in
danger of extinction or likely to become
so in the foreseeable future in that
portion.
We identified another portion, the
Upper Coosa River (F) representation
unit, of the frecklebelly madtom’s range
that is experiencing a concentration of
the following threat, but at a biologically
meaningful scale: Habitat destruction
and degradation from agriculture and
developed land uses resulting in poor
water quality (Factor A). Currently,
within the Upper Coosa River (F)
representation unit, two resilience units
(Conasauga River (F1) and Etowah River
(F3)) have low and moderate resiliency,
respectively; the Coosawattee (F2)
resilience unit was determined to have
an unknown resiliency as the species
was not historically known to occur in
this river, but eDNA for the frecklebelly
madtom was found in portions of this
unit in 2018. Declines from historical
condition in frecklebelly madtom
occurrences have been apparent in the
Conasauga River (F1) resilience unit,
while occurrence records in the Etowah
River (F3) resilience unit are fairly
widespread and considered similar to
historical occurrence records. Given the
current resiliency of units within the
Upper Coosa River (F) representation
unit, it is not likely a single catastrophic
event would result in the extirpation of
the species from this portion.
In the foreseeable future, we project
the Upper Coosa River (F)
representation unit will have declines in
resiliency for both the Conasauga River
(F1) and Etowah River (F3) resilience
units due to habitat destruction and
degradation from agriculture and
developed land use. Although this
threat is not unique to the Upper Coosa
River (F) representation unit, the threat
in this portion is great enough to project
a reduction in resiliency for both of
these resilience units, and, therefore, the
entire representation unit is expected to
decline. In the Etowah River (F3)
resilience unit, urbanization under the
low, moderate, and high development
scenarios is projected to increase and
comprise 35, 38, and 42 percent of the
watershed, respectively, as compared to
14 percent of the watershed currently.
Within the Conasauga River (F1)
resilience unit, urbanization is projected
to increase and comprise 13, 15, and 17
percent of the watershed under the low,
moderate, and high development
scenarios, as compared to 8 percent of
the watershed currently. This projected
urbanization coupled with continued
agricultural activities will continue to
impair, and potentially further decrease,
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
stream habitat and water quality in the
Conasauga River (F1) resilience unit,
which already has elevated nitrogen,
phosphorus, turbidity, and
concentrations of bioavailable estrogen
(Freemen et al. 2017, pp. 429–430). In
addition, the future scenarios project the
Etowah River (F3) and Conasauga River
(F1) units to have low resiliency (under
the moderate development scenario)
and to have low resiliency and be likely
extirpated, respectively (under the high
development scenario), by the year
2050. This would significantly increase
the risk of extirpation of the Upper
Coosa (F) representation unit from a
catastrophic or stochastic event. Our
examination leads us to find that there
is substantial information that the
Upper Coosa River (F) representation
unit is likely to become in danger of
extinction within the foreseeable future.
We then proceeded to consider
whether this portion of the range (i.e.,
the Upper Coosa River (F)
representation unit) is significant. For
the purposes of this analysis, the
Service is considering significant
portions of the range by applying any
reasonable definition of ‘‘significant.’’
We asked whether any portions of the
range may be biologically meaningful in
terms of the resiliency, redundancy, or
representation of the entity being
evaluated. This approach is consistent
with the Act, our implementing
regulations, our policies, and case law.
We evaluated the available
information about the portion of the
species that occupies the Upper Coosa
River representation unit, assessing its
significance. Throughout most of its
range, the frecklebelly madtom occurs
in rivers within the Gulf Coastal Plain
physiographic province, which is an
area comprising the former continental
shelf and is currently above sea level
(Fennemann 1928, p. 280). The Upper
Coosa River (F) representation unit
occurs in the Ridge and Valley
(Conasauga River (F1) and Coosawattee
River (F2) resilience units) and
Piedmont Upland (Etowah River (F3)
resilience unit) physiographic
provinces. Physiographic provinces are
regions divided into distinctive
geographic areas based on physical
geography, such as topography, soil
type, and geologic history (Fenneman
1928, pp. 266–272), where areas with
similar characteristics are grouped into
a province. The Piedmont province
contains lowlands (plains) and
highlands (plateaus) with isolated
mountains, and in Georgia, the elevation
reaches up to 480 meters (1,500 feet)
(Fennemann 1928, p. 293); the Ridge
and Valley province contain a
longitudinal series of valleys (lowlands)
PO 00000
Frm 00016
Fmt 4701
Sfmt 4702
and ridges (mountains) through the
Appalachians (Fennemann 1928, p.
296). Given the Upper Coosa River (F)
representation unit occurs in different
physiographic provinces with a
distinctive physical geography from the
rest of the range, frecklebelly madtoms
in this unit may experience
environmental conditions, such as soils,
water chemistry, hydrological regimes,
and nutrient cycling, that are different
from the rest of the range. These rivers
in the Upper Coosa River (F)
representation unit, flowing through
unique physiographic provinces, are
also removed from the nearest Coastal
Plain physiographic province resilience
units by approximately 418 river miles
(673 river kilometers) and represent the
most eastern and northern resilience
units of the frecklebelly madtom.
Historically and currently, the Upper
Coosa River (F) representation unit
represents a small portion (less than 15
percent based on current occurrences
and occupied stream reaches; less than
24 percent based on historical
occurrences) of the frecklebelly
madtom’s range. If the Upper Coosa
River (F) representation unit was
extirpated, the frecklebelly madtom
would lose some representation and
redundancy, but the loss of this portion
of the species’ range would still leave
sufficient resiliency (populations with
moderate to high resiliency),
redundancy, and representation in the
remainder of the species’ range such
that it would not notably reduce the
viability of the species. Therefore,
despite the Upper Coosa River (F)
representation unit occurring in
different physiographic provinces and
being disjunct from the remainder of the
range, this unit only represents a small
portion of the frecklebelly madtom’s
historical and current range and does
not represent a significant portion of the
frecklebelly madtom’s range. We
conclude that the frecklebelly madtom
is not in danger of extinction or likely
to become so in the foreseeable future in
a significant portion of its range. Our
approach is consistent with the courts’
holdings in Desert Survivors v.
Department of the Interior, 321 F. Supp.
3d 1011 (N.D. Cal. 2018), and Center for
Biological Diversity v. Jewell, 248 F.
Supp. 3d, 946, 959 (D. Ariz. 2017).
We have carefully assessed the best
scientific and commercial information
available regarding the past, present,
and future threats to the frecklebelly
madtom. Because the species is neither
in danger of extinction now nor likely
to become so in the foreseeable future
throughout all or any significant portion
of its range, the frecklebelly madtom
does not meet the definition of an
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
endangered species or threatened
species. Therefore, we find that listing
the frecklebelly madtom as an
endangered or threatened species under
the Act is not warranted at this time.
This constitutes the conclusion of the
Service’s 12-month finding on the 2010
petition to list the frecklebelly madtom
as an endangered or threatened species.
A detailed discussion of the basis for
this finding can be found in the SSA
report and other supporting documents
(available on the internet at https://
www.regulations.gov under Docket No.
FWS–R4–ES–2020–0058).
We ask the public to submit to us any
new information that becomes available
concerning the taxonomy, biology,
ecology, or status of the frecklebelly
madtom, or stressors to the frecklebelly
madtom, whenever it becomes available.
Please submit any new information,

Distinct Population Segment (DPS)
Analysis
Under the Act, we have the authority
to consider for listing any species,
subspecies, or, for vertebrates, any
distinct population segment (DPS) of
these taxa if there is sufficient
information to indicate that such action
may be warranted. To guide the
implementation of the DPS provisions
of the Act, we and the National Marine
Fisheries Service (National Oceanic and
Atmospheric Administration—
Fisheries), published the Policy
Regarding the Recognition of Distinct
Vertebrate Population Segments Under
the Endangered Species Act (DPS
Policy) in the Federal Register on
February 7, 1996 (61 FR 4722). Under
our DPS Policy, we use two elements to
assess whether a population segment
under consideration for listing may be
recognized as a DPS: (1) The population
segment’s discreteness from the
remainder of the species to which it
belongs, and (2) the significance of the
population segment to the species to
which it belongs. If we determine that

for listing is a DPS, then the population
segment’s conservation status is
evaluated based on the five listing
factors established by the Act to
determine if listing it as either
endangered or threatened is warranted.
The Upper Coosa River (F)
representation unit consists of the
Conasauga River, Coosawattee River,
Etowah River, and their tributaries and
watersheds (see figure 1, below). The
Coosawattee River joins the Conasauga
River to form the Oostanaula River, and
the Etowah River joins the Oostanaula
River to form the Coosa River. Within
this proposed rule, we refer to the
Upper Coosa River (F) representation
unit as including all rivers and streams
in the upper Coosa River basin that join
to form the Coosa River; in other words,
the entire watershed upstream from the
confluence of the Oostanaula and
Etowah Rivers. Below, we evaluated the
Upper Coosa River representation unit
of the frecklebelly madtom’s range to
determine whether it meets the
definition of a DPS under our DPS
Policy.

Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
The Upper Coosa River (F)
representation unit of the frecklebelly
madtom is markedly separate from other
representation and resilience units of
the species both genetically and
geographically. In terms of morphology
and genetics, the frecklebelly madtom
has exhibited some morphological and
genetic differences across representation
units. Preliminary data suggested there
was considerable morphological
variation across the species’ range, and
the populations in the Coosa River
drainage were the most distinctive
population (Neely 2018, p. 1). Given
this information, it was thought that
frecklebelly madtoms in the Conasauga
and Etowah Rivers may be distinct from
frecklebelly madtoms found elsewhere.
Through a reanalysis of existing
morphological and genetic data,
frecklebelly madtoms collected from the
Coosa River drainage were found to
have shorter snout to barbel midpoint
distance measurements than madtoms
collected from other drainages, but this
difference was not diagnostic of this
population as there is overlap in the
range of measurements among
populations (Neely 2018, p. 7). In terms
of genetic variation, considerable
genetic differentiation was observed
among the Pearl, Tombigbee, Cahaba,
and Coosa Rivers populations; however,
morphological variation was
incongruent with genetic variation
(Neely 2018, p. 10). These results ‘‘do
not allow clear diagnosis of distinct
species within Noturus munitus’’ (Neely
2018, p. 10). Because the data do not
support the description of a distinct
subspecies or species, each population
of frecklebelly madtom is recommended
to be considered as a separate
evolutionary significant unit or ESU of
the frecklebelly madtom (Neely 2018, p.
10). Therefore, the Upper Coosa River
(F) representation unit is considered an
ESU of the frecklebelly madtom, which
provides key representation for the
frecklebelly madtom as a whole.
The Upper Coosa River (F)
representation unit also consists of
separate and distinct physiographic
provinces as compared to the majority
of the species’ range, as discussed above
under Status Throughout a Significant
Portion of Its Range. In terms of physical
or geographic separation, the resilience
units in the Upper Coosa River (F)
representation unit are disjunct from
other units of the frecklebelly madtom
across the species’ range. The distance
of the geographic separation from other
frecklebelly madtom representation and
resilience units is approximately 418
river miles (673 river kilometers)
upstream with seven dams (Weiss, H.

Neely Henry, Logan Martin, Lay,
Mitchell, Jordan, and R.F. Henry) and
impoundments disrupting the
connectivity and creating barriers to
movement to the rest of the range.
Therefore, frecklebelly madtoms in the
Upper Coosa River (F) representation
unit currently do not, and will likely
never, naturally interact with
individuals or populations in the
remaining part of the range. In addition,
if this portion becomes extirpated,
frecklebelly madtoms located within the
Coastal Plain physiographic province
may be unable to recolonize the Upper
Coosa River (F) representation unit, not
only due to the lack of connectivity, but
also because they may lack the needed
adaptive traits to survive in these
different physical geographies. Based on
our review of the available information,
we conclude that the Upper Coosa River
representation unit of the frecklebelly
madtom is markedly separate from other
representation and resilience units of
the species due to genetic separation
and geographic (physical) isolation from
frecklebelly madtoms in the remainder
of the range. Therefore, we have
determined that the Upper Coosa River
representation unit of the frecklebelly
madtom meets the condition for
discreteness under our DPS Policy.
Significance
Under our DPS Policy, once we have
determined that a population segment is
discrete, we consider its biological and
ecological significance to the larger
taxon to which it belongs. This
consideration may include, but is not
limited to: (1) Evidence of the
persistence of the discrete population
segment in an ecological setting that is
unusual or unique for the taxon, (2)
evidence that loss of the population
segment would result in a significant
gap in the range of the taxon, (3)
evidence that the population segment
represents the only surviving natural
occurrence of a taxon that may be more
abundant elsewhere as an introduced
population outside its historical range,
or (4) evidence that the discrete
population segment differs markedly
from other populations of the species in
its genetic characteristics. Of particular
note, as we explained in our draft (76
FR 76987, December 9, 2011, p. 76998)
and final (79 FR 37577, July 1, 2014, pp.
79 FR 37579, 37585) Policy on
Interpretation of the Phrase ‘‘Significant
Portion of Its Range’’ in the Endangered
Species Act’s Definitions of
‘‘Endangered Species’’ and ‘‘Threatened
Species’’ (SPR Policy), the definition of
‘‘significant’’ for the purpose of
significant portion of the range analysis
differs from the definition of
PO 00000
Frm 00019
Fmt 4701
Sfmt 4702
74067
‘‘significant’’ found in our DPS Policy
and used for DPS analysis. Although
there are similarities in the definition of
‘‘significant’’ under the SPR Policy and
the definition of ‘‘significance’’ in the
DPS Policy, there are important
differences between the two. The DPS
Policy requires that for a vertebrate
population to meet the Act’s definition
of ‘‘species,’’ it must be discrete from
other populations and must be
significant to the taxon as a whole. The
significance criterion under the DPS
Policy is necessarily broad and could be
met under a wider variety of
circumstances even if it could not be
met under the SPR Policy. In this case,
we determine (see below) that the Upper
Coosa River (F) representation unit is
‘‘significant’’ for the purposes of DPS,
and we did not, as discussed above,
conclude that it constituted a
‘‘significant’’ portion of the frecklebelly
madtom’s range.
Currently, the Upper Coosa River (F)
representation unit is one of four known
extant units within the species. We
determined that loss of this unit
(population segment) would result in a
significant gap in the species’ range. The
Upper Coosa River (F) representation
unit in Georgia and Tennessee
represents the eastern and northernmost
portion of the frecklebelly madtom’s
range, with the remainder of the range
occurring in Louisiana, Mississippi, and
Alabama. As discussed previously, this
unit also occurs in different
physiographic provinces (Ridge and
Valley province and Piedmont Upland
province) associated with different
environmental and physical conditions.
Lastly, the Upper Coosa River (F)
representation unit is approximately
418 river miles (673 kilometers) from
the nearest resilience units in the
Coastal Plain province. Therefore, the
loss of this unit would result in the
species’ range shifting south and west
approximately 418 miles (673
kilometers).
As with other representation units,
the Upper Coosa River (F)
representation unit of the frecklebelly
madtom differs markedly from other
populations of the species in its genetic
characteristics. As discussed above,
considerable genetic differentiation has
been observed among populations of
frecklebelly madtom (Neely 2018, p. 10),
and these populations are considered
evolutionary significant units of
frecklebelly madtom. In addition, the
Upper Coosa River (F) representation
unit of the frecklebelly madtom persists
in different physiographic provinces
than the remainder of the range. The
Upper Coosa River (F) representation
unit occurs in the Ridge and Valley
E:\FR\FM\19NOP2.SGM
19NOP2
74068
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
(Conasauga River (F1) and Coosawattee
River (F2) resilience units) and
Piedmont Upland (Etowah River (F3)
resilience unit) physiographic
provinces, while the rest of the range
occurs in rivers within the Gulf Coastal
Plain physiographic province. Having
persisted over time in areas with
distinctive physical geography,
frecklebelly madtoms in the Upper
Coosa River (F) representation unit have
likely adapted to environmental
conditions, such as soils, water
chemistry, hydrological regimes, and
nutrient cycling, differently, as
demonstrated by the divergent genetics
described by Neely (2018, entire), and
have likely contributed to the adaptive
capacity of the species. The adaptations
of frecklebelly madtoms are an
important and unique component of the
species’ representation, which is
evidence of it differing markedly from
other populations of the species in its
genetics. Therefore, we have substantial
evidence that the Upper Coosa River (F)
representation unit of the frecklebelly
madtom differs markedly in its genetic
characteristics, as it is considered an
evolutionary significant unit, and loss of
this genetic diversity would likely
impact the species’ adaptive capacity.
However, although the loss of the Upper
Coosa River (F) representation unit
would likely result in a reduction in
species’ redundancy, and, therefore, the
species’ adaptive capacity, it would not
notably reduce the viability of the
species across the range (see above
under Status Throughout a Significant
Portion of Its Range).
Given the evidence that the Upper
Coosa River (F) representation unit of
the frecklebelly madtom would result in
a significant gap in the range if lost, and
that the unit differs markedly from other
populations of the species, we consider
this unit to be significant to the species
as a whole. Thus, the Upper Coosa River
(F) representation unit of the
frecklebelly madtom meets the criteria
for significance under our DPS Policy.
DPS Conclusion for the Upper Coosa
River Representation Unit of the
Frecklebelly Madtom
Our DPS Policy directs us to evaluate
the significance of a discrete population
in the context of its biological and
ecological significance to the remainder
of the species to which it belongs. Based
on an analysis of the best available
scientific and commercial data, we
conclude that the Upper Coosa River (F)
representation unit of the frecklebelly
madtom is discrete due to genetic
separation and geographic (physical)
isolation from the remainder of the
taxon. Furthermore, we conclude that
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
the Upper Coosa River representation
unit of the frecklebelly madtom is
significant, as described above.
Therefore, we conclude that the Upper
Coosa River (F) representation unit of
the frecklebelly madtom is both discrete
and significant under our DPS Policy
and is, therefore, a listable entity under
the Act.
Based on our DPS Policy (61 FR 4722;
February 7, 1996), if a population
segment of a vertebrate species is both
discrete and significant relative to the
taxon as a whole (i.e., it is a distinct
population segment), its evaluation for
endangered or threatened status will be
based on the Act’s definition of those
terms and a review of the factors
enumerated in section 4(a) of the Act.
Having found that the Upper Coosa
River (F) representation unit of the
frecklebelly madtom meets the
definition of a distinct population
segment, we now evaluate the status of
this DPS to determine whether it meets
the definition of an endangered or
threatened species under the Act.
Status Throughout All of the DPS’s
Range
In the analysis above for the
frecklebelly madtom as a whole, we
have carefully assessed the best
scientific and commercial information
available regarding the past, present,
and future threats to the Upper Coosa
River DPS of the species. We considered
whether the Upper Coosa River DPS of
the frecklebelly madtom is presently in
danger of extinction throughout all of its
range. The Upper Coosa River
representation unit faces ongoing and
future threats from habitat destruction
and degradation caused by agriculture
and developed land uses resulting in
poor water quality. As discussed above
under Status Throughout a Significant
Portion of Its Range, occurrence records
in the Etowah River (F3) resilience unit
are considered similar to historical
occurrence records, whereas there have
been declines from historical conditions
in frecklebelly madtom occurrences in
the Conasauga River (F1) resilience unit.
Evidence of the frecklebelly madtom
presence was first reported from the
Coosawattee River (F2) from eDNA
collected in 2018. Until eDNA for the
species was recorded from this river, the
frecklebelly madtom was not expected
occur there, given that the history of
physical modification to improve
navigation, as well as hydropeaking at
Carters Dam, upstream has negatively
affected small-bodied, riffle-dwelling
fish species (Freeman et al. 2011, pp.
10–11). However, given the current
resiliency of units within the Upper
Coosa River (F) representation unit, it is
PO 00000
Frm 00020
Fmt 4701
Sfmt 4702
not likely that the current threats, or the
cumulative effects of those threats, will
result in the extirpation of the DPS.
Therefore, the DPS is not currently in
danger of extinction throughout its
range.
In the future, projected urbanization
and continued agricultural activities
will continue to impact the Upper Coosa
River DPS and its habitat by negatively
affecting water quality (Factor A). Our
future scenarios project the Etowah
River (F3) and Conasauga River (F1)
units in the Upper Coosa River (F)
representation unit to have low
resiliency or to become extirpated by
the year 2050, and this would
significantly increase the risk of
extirpation of the Upper Coosa River (F)
representation unit from the
aforementioned threats, as well as a
catastrophic or stochastic event, within
the foreseeable future. In our
consideration of foreseeable future, we
evaluated how far into the future we
could reliably predict the threats to this
unit, as well as the madtom’s response
to those threats. Based on the modeling
and scenarios (agriculture and
developed land use projections to 2050)
evaluated, we considered our ability to
make reliable predictions in the future
and the uncertainty in how and to what
degree the unit could respond to those
risk factors in this timeframe. We
determined a foreseeable future of 30
years for the Upper Coosa River
representation unit. Based on this
information, we find the Upper Coosa
River DPS of the frecklebelly madtom is
likely to become endangered within the
foreseeable future throughout all of its
range. Therefore, we consider the Upper
Coosa River DPS to be threatened
throughout all of its range.
Status Throughout a Significant Portion
of the DPS’s 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 in the foreseeable
future throughout all or a significant
portion of its range. The court in Center
for Biological Diversity v. Everson, 2020
WL 437289 (D.D.C. Jan. 28, 2020)
(Center for Biological Diversity), vacated
the aspect of the SPR Policy (79 FR
37577; July 1, 2014) that provided that
the Service does not undertake an
analysis of significant portions of a
species’ range if the species warrants
listing as threatened throughout all of its
range. Therefore, we proceed to
evaluating whether the species (DPS) 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
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
(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
Center for Biological Diversity, 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 Upper
Coosa River DPS of the frecklebelly
madtom, we chose to address the status
question first—we consider information
pertaining to the geographic 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 considered whether
the threats acting on the Upper Coosa
River DPS are geographically
concentrated in any portion of the range
at a biologically meaningful scale. We
examine the following threats that were
considered to be primary factors driving
current resiliency of the Upper Coosa
River DPS: Habitat destruction and
degradation caused by agriculture and
developed land uses resulting in poor
water quality (Factor A).
Habitat destruction and degradation
from agriculture and developed land
uses resulting in poor water quality is
occurring throughout the range of the
Upper Coosa River DPS. In the
Conasauga River (F1) resilience unit,
current development and agriculture
comprises 8.0 percent and 21.3 percent
of the watershed, respectively (Service
2020, pp. 66–69). In the Coosawattee
River (F2) resilience unit, current
development and agriculture comprises
6.6 percent and 27.2 percent of the
watershed, respectively (Service 2020,
pp. 66–69). Lastly, current development
and agriculture comprises 14.8 percent
and 10.4 percent of the Etowah River
(F3) resilience unit (Service 2020, pp.
66–69). For the three resilience units
assessed within the DPS, approximately
25 to 33 percent of each unit is currently
impacted by agricultural and developed
land uses. Therefore, we found no
concentration of threats in any portion
of the Upper Coosa River DPS’s range at
a biologically meaningful scale.
However, we identified one portion, the
Conasauga River (F1) resilience unit,
which currently has low resiliency and
where the frecklebelly madtom has not
been observed, despite repeated
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
surveys, in at least 20 years.
Environmental DNA surveys have
detected the frecklebelly madtom in the
Conasauga River (F1) resilience unit,
leading us to determine the species
remains present there. However, the
lack of recent occurrence data coupled
with projections that this unit will
become extirpated within the
foreseeable future led us to find there is
substantial information that the
Conasauga River (F1) resilience unit
may be endangered.
We then proceeded to consider
whether this portion of the range (i.e.,
the Conasauga River (F1) resilience unit)
is significant. For purposes of this
analysis, the Service is examining for
significant portions of the range by
applying any reasonable definition of
‘‘significant.’’ We asked whether any
portions of the range may be
biologically meaningful in terms of the
resiliency, redundancy, or
representation of the entity being
evaluated. This approach is consistent
with the Act, our implementing
regulations, our policies, and case law.
The Upper Coosa River (F)
representation unit occurs in the Ridge
and Valley (Conasauga River (F1)
resilience unit) and Piedmont Upland
(Etowah River (F3) resilience unit)
physiographic provinces. As discussed
above under Status Throughout a
Significant Portion of Its Range for the
frecklebelly madtom as a whole,
physiographic provinces are geographic
areas divided based on physical
geography and grouped by similar
characteristics (Fenneman 1928, pp.
266–272). The Conasauga River (F1)
resilience unit occurs in the Ridge and
Valley province, which contains a series
of valleys (lowlands) and ridges
(mountains) through the Appalachians
(Fennemann 1928, p. 296). The Etowah
River (F3) resilience unit occurs in the
Piedmont province, which contains
lowlands (plains) and highlands
(plateaus) with isolated mountains
(Fennemann 1928, p. 293). These two
resilience units may occur in two
physiographic provinces; however, the
geography in both represents
environmental and physical conditions
of lowlands and highlands associated
with higher elevations than the
remainder of the species’ range in the
Coastal Plain province. Frecklebelly
madtoms collected in both the
Conasauga River (F1) and Etowah River
(F3) resilience units are strongly
associated with river weed
(Podostemum spp.) used for cover and
shelter. Neither unit acts as a refugia or
an important spawning ground for the
DPS. In addition, the Conasauga River
(1) resilience unit watershed is
PO 00000
Frm 00021
Fmt 4701
Sfmt 4702
74069
experiencing similar impacts from
development and agricultural land-use
to the Etowah River (F3) resilience unit.
Since the Upper Coosa River DPS of the
frecklebelly madtom occurs in rivers
with similar physical and
environmental conditions, and the
Conasauga River (F1) resilience unit
portion is experiencing similar water
quality impacts as the remainder of the
DPS’s range, there is no unique
observable environmental usage or
behavioral characteristics attributable to
just this portion that would make it a
significant portion of the range of the
Upper Coosa River DPS.
Overall, there is little evidence to
suggest that the Conasauga River (F1)
portion of the range has higher quality
or higher value habitat or any other
special importance to the species’ life
history in the Upper Coosa River DPS.
We considered if the Conasauga River
(F1) portion contributes to biological
significance in any way listed above and
did not find this portion to be
prominent or noteworthy in a manner
that would suggest it is a significant
portion of the DPS’s range. Thus, based
on the best available information, we
find that this portion of the DPS’s range
is not biologically significant. Therefore,
no portion of the Upper Coosa River
DPS’s range provides a basis for
determining that it is in danger of
extinction in a significant portion of its
range. This is consistent with the courts’
holdings in Desert Survivors v.
Department of the Interior, No. 16–cv–
01165–JCS, 2018 WL 4053447 (N.D. Cal.
Aug. 24, 2018), and Center for Biological
Diversity v. Jewell, 248 F. Supp. 3d, 946,
959 (D. Ariz. 2017).
Determination of Status
We evaluated threats to the
frecklebelly madtom and assessed the
cumulative effect of the threats under
the Act’s section 4(a)(1) factors and
conclude the species, viewed across its
entire range, experiences a low risk of
extinction. Based on the best available
scientific and commercial information
as presented in the SSA report and this
finding, we do not find that the
frecklebelly madtom is currently in
danger of extinction throughout all or a
significant portion of its range, nor is it
likely to become so in the foreseeable
future. However, we did find the Upper
Coosa River representation unit is a
valid DPS, and this DPS of the
frecklebelly madtom is likely to become
endangered within the foreseeable
future throughout all of its range.
Therefore, we propose to list the Upper
Coosa River DPS of the frecklebelly
madtom as a threatened species
throughout all of its range in accordance
E:\FR\FM\19NOP2.SGM
19NOP2
74070
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
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, 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, 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
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 these 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 recovery
planning process involves the
identification of actions that are
necessary to halt or reverse the species’
decline by addressing the threats to its
survival and recovery. The goal of this
process is to restore listed species to a
point where they are secure, selfsustaining, and functioning components
of their ecosystems.
Recovery planning consists of
preparing draft and final recovery plans,
beginning with the development of a
recovery outline and making it available
to the public within 30 days of a final
listing determination. The recovery
outline guides the immediate
implementation of urgent recovery
actions and describes the process to be
used to develop a recovery plan.
Revisions of the plan may be done to
address continuing or new threats to the
species, as new substantive information
becomes available. The recovery plan
also 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. Recovery teams
(composed of species experts, Federal
and State agencies, nongovernmental
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
organizations, and stakeholders) are
often established to develop recovery
plans. When completed, the recovery
outline, draft recovery plan, and the
final recovery plan will be available on
our website (https://www.fws.gov/
endangered), or from our Alabama
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 (e.g., 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.
If 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 Georgia and Tennessee
would be eligible for Federal funds to
implement management actions that
promote the protection or recovery of
the Upper Coosa River DPS of the
frecklebelly madtom. Information on
our grant programs that are available to
aid species recovery can be found at:
https://www.fws.gov/grants.
Although the Upper Coosa River DPS
of the frecklebelly madtom is only
proposed for listing under the Act at
this time, please let us know if you are
interested in participating in recovery
efforts for this species. 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(a) of the Act requires
Federal agencies to evaluate their
actions with respect to any species that
is proposed or listed as an endangered
or threatened species and with respect
to its critical habitat, if any is
designated. Regulations implementing
this interagency cooperation provision
of the Act are codified at 50 CFR part
402. Section 7(a)(4) of the Act requires
Federal agencies to confer with the
Service on any action that is likely to
jeopardize the continued existence of a
PO 00000
Frm 00022
Fmt 4701
Sfmt 4702
species proposed for listing or result in
destruction or adverse modification of
proposed critical habitat. If a species is
listed subsequently, section 7(a)(2) of
the Act requires Federal agencies to
ensure that activities they authorize,
fund, or carry out are not likely to
jeopardize the continued existence of
the species or destroy or adversely
modify its critical habitat. If a Federal
action may affect a listed species or its
critical habitat, the responsible Federal
agency must enter into consultation
with the Service.
Federal agency actions within the
species’ habitat that may require
conference or consultation or both as
described in the preceding paragraph
include management and any other
landscape-altering activities on Federal
lands administered, or on private lands
seeking funding by Federal agencies,
which may include, but are not limited
to, the USDA U.S. Forest Service, USDA
Farm Service Agency, USDA Natural
Resources Conservation Service, and
Federal Emergency Disaster Service;
issuance of section 404 Clean Water Act
(33 U.S.C. 1251 et seq.) permits by the
U.S. Army Corps of Engineers; and
construction and maintenance of roads
or highways by the Federal Highway
Administration.
It is our policy, as published in the
Federal Register on July 1, 1994 (59 FR
34272), to identify to the maximum
extent practicable at the time a species
is listed, those activities that would or
would not constitute a violation of
section 9 of the Act. The intent of this
policy is to increase public awareness of
the effect of a proposed listing on
proposed and ongoing activities within
the range of the species proposed for
listing. The discussion below regarding
protective regulations under section 4(d)
of the Act complies with our policy.
II. Proposed Rule Issued 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 he deems necessary and
advisable to provide for the
conservation of species listed as
threatened. The U.S. Supreme Court has
noted that statutory language like
‘‘necessary and advisable’’ demonstrates
a large degree of deference to the agency
(see Webster v. Doe, 486 U.S. 592
(1988)). 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
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
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. Thus, the combination of the
two sentences of section 4(d) provides
the Secretary with wide latitude of
discretion to select and promulgate
appropriate regulations tailored to the
specific conservation needs of the
threatened species. The second sentence
grants particularly broad discretion to
the Service when adopting the
prohibitions under section 9.
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 rules developed under section
4(d) as a valid exercise of agency
authority where they prohibited take of
threatened wildlife or include a limited
taking prohibition (see Alsea Valley
Alliance v. Lautenbacher, 2007 U.S.
Dist. Lexis 60203 (D. Or. 2007);
Washington Environmental Council v.
National Marine Fisheries Service, 2002
U.S. Dist. Lexis 5432 (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 him with regard to the
permitted activities for those species. He
may, for example, permit taking, but not
importation of such species, or 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).
Exercising our authority under section
4(d), we have developed a proposed rule
that is designed to address the specific
threats and conservation needs for the
Upper Coosa River DPS of the
frecklebelly madtom. Although the
statute does not require us to make a
‘‘necessary and advisable’’ finding with
respect to the adoption of specific
prohibitions under section 9, we find
that this rule as a whole satisfies the
requirement in section 4(d) of the Act to
issue regulations deemed necessary and
advisable to provide for the
conservation of the Upper Coosa River
DPS of frecklebelly madtom. As
discussed above under Summary of
Biological Status and Threats, we have
concluded that the Upper Coosa River
DPS is likely to become in danger of
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
extinction within the foreseeable future
primarily due to habitat destruction and
degradation from agriculture and
developed land uses resulting in poor
water quality. The provisions of this
proposed 4(d) rule would promote
conservation of the Upper Coosa River
DPS by encouraging management of the
landscape in ways that meet both
watershed and riparian management
purposes and the conservation needs of
the Upper Coosa River DPS. The
provisions of this proposed rule are one
of many tools that we would use to
promote the conservation of the Upper
Coosa River DPS. This proposed 4(d)
rule would apply only if and when we
make final the listing of the Upper
Coosa River DPS as a threatened
species.
Provisions of the Proposed 4(d) Rule
This proposed 4(d) rule would
provide for the conservation of the
Upper Coosa River DPS by prohibiting
the following activities, except as
otherwise authorized or permitted:
Import or export (see proposed
§ 17.44(ee)(1)(i)); take (see proposed
§ 17.44(ee)(1)(ii)); possession and other
acts with unlawfully taken specimens
(see proposed § 17.44(ee)(1)(iii));
delivery, receipt, transport, or shipment
in interstate or foreign commerce in the
course of commercial activity (see
proposed § 17.44(ee)(1)(iv)); and sale or
offer for sale in interstate or foreign
commerce (see proposed
§ 17.44(ee)(1)(v)). We also include
several exceptions to these prohibitions,
which along with the prohibitions are
set forth under Proposed Regulation
Promulgation, below.
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, unintentionally,
or incidentally. Protecting the Upper
Coosa River DPS of the frecklebelly
madtom from direct forms of take, such
as physical injury or killing, whether
incidental or intentional, will help
preserve and recover the remaining
populations of the DPS. Therefore, we
prohibit intentional take of frecklebelly
madtom, including, but not limited to,
capturing, handling, trapping,
collecting, or other activities (see
proposed § 17.44(ee)(1)(ii)). Also, as
discussed above under Summary of
Biological Status and Threats, habitat
destruction and degradation from
agriculture and developed land uses are
affecting the status of the Upper Coosa
PO 00000
Frm 00023
Fmt 4701
Sfmt 4702
74071
River DPS. Across the DPS’s range,
stream and water quality have been
degraded physically by sedimentation,
pollution, contaminants,
impoundments, channelization,
destruction of riparian habitat, and loss
of riparian vegetation due to agriculture
activities and development within the
watershed and riparian areas. Other
habitat or hydrological alteration, such
as ditching, draining, stream diversion,
or diversion or alteration of surface or
ground water flow, into or out of the
stream will impact the habitat of the
DPS. Therefore, we prohibit actions that
result in the incidental take of the
Upper Coosa River DPS by destroying,
altering, or degrading the habitat in the
manner described above (see proposed
§ 17.44(ee)(1)(ii)). Regulating these
activities would help preserve the DPS’s
remaining populations, slow the rate of
population decline, and decrease
synergistic, negative effects from other
stressors.
Exceptions to Prohibitions
In addition to certain statutory
exceptions from prohibitions, which are
found in sections 9 and 10 of the Act,
the proposed 4(d) rule includes the
following exceptions to the
prohibitions:
Permitted Activities
We may issue permits to carry out
otherwise prohibited activities,
including those described above,
involving threatened wildlife under
certain circumstances (see proposed
§ 17.44(ee)(2)(i)). Regulations governing
permits are codified at 50 CFR 17.32.
With regard to threatened wildlife, a
permit may be 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 Act. There
are also certain statutory exemptions
from the prohibitions, which are found
in sections 9 and 10 of the Act.
Activities Not Requiring a Permit
We recognize the special and unique
relationship 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 the Service in
implementing all aspects of the Act. In
E:\FR\FM\19NOP2.SGM
19NOP2
74072
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
this regard, section 6 of the Act provides
that the Service shall 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 the Service
in accordance with section 6(c) of the
Act, who is designated by his or her
agency for such purposes, would be able
to conduct activities designed to
conserve the Upper Coosa River DPS
that may result in otherwise prohibited
take without additional authorization
(see proposed § 17.44(ee)(2)(iii)).
We may allow take of the individuals
of the Upper Coosa River DPS without
a permit by any employee or agent of
the Service or a State conservation
agency designated by his agency for
such purposes and when acting in the
course of his official duties if such
action is necessary to aid a sick, injured
or orphaned specimen; dispose of a
dead specimen; or salvage a dead
specimen which may be useful for
scientific study (see proposed
§ 17.44(ee)(2)(ii)). In addition, Federal
and State law enforcement officers may
possess, deliver, carry, transport, or ship
specimens taken in violation of the Act
as necessary (see proposed
§ 17.44(ee)(2)(v)).
Channel Restoration, Streambank
Stabilization, and Other Activities
Channel restoration is used as a
technique to restore degraded,
physically unstable streams back to
natural, physically stable, ecologically
functioning streams. When done
correctly, these projects reduce,
ameliorate, or fix unnatural erosion,
head cutting, and/or sedimentation.
Thus, channel restoration projects result
in geomorphically stable stream
channels that maintain the appropriate
lateral dimensions, longitudinal
profiles, and sinuosity patterns over
time without an aggrading or degrading
bed elevation and include stable rifflerun-pool complexes that consist of siltfree gravel, coarse sand, cobble,
boulders, woody structure, and river
weed (Podostemum spp.). This
provision of the proposed 4(d) rule for
channel restoration would promote
conservation of the Upper Coosa River
DPS by excepting incidental take
resulting from activities that would
improve channel conditions and restore
degraded, physically unstable streams
or stream segments (see proposed
§ 17.44(ee)(2)(iv)(A)). We anticipate
these activities will advance ecological
conditions within a watershed to a more
natural state that will benefit the
frecklebelly madtom.
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
Streambank stabilization is used as a
habitat restoration technique to restore
degraded and eroded streambanks back
to natively vegetated, stable
streambanks. When done correctly,
these projects reduce bank erosion and
instream sedimentation, resulting in
improved habitat conditions for aquatic
species. Therefore, we would allow
streambanks to be stabilized using the
following bioengineering methods: Live
stakes (live, vegetative cuttings inserted
or tamped into the ground in a manner
that allows the stake to take root and
grow), live fascines (live branch
cuttings, usually willows, bound
together into long, cigar-shaped
bundles), planting of bare-root seedlings
or brush layering (cuttings or branches
of easily rooted tree species layered
between successive lifts of soil fill). All
methods should use plant species native
to the region where the project is being
conducted. These methods would not
include the sole use of quarried rock
(rip-rap) or the use of rock baskets or
gabion structures, but could be used in
conjunction with the above
bioengineering methods. This provision
of the proposed 4(d) rule for streambank
stabilization would promote
conservation of the Upper Coosa River
DPS by excepting from the prohibition
incidental take resulting from activities
that would improve habitat conditions
by reducing bank erosion and instream
sedimentation (see proposed
§ 17.44(ee)(2)(iv)(B)).
Improving watershed, riparian, and
habitat conditions within the range of
the Upper Coosa River DPS would
provide for the conservation of the DPS
and would likely increase resiliency in
the Etowah River and Conasauga River
resilience units. Activities carried out
under the Working Lands for Wildlife
(WLFW) program of the Natural
Resources Conservation Service (NRCS),
U.S. Department of Agriculture, or
similar projects, which may include
projects funded by the Service’s
Partners for Fish and Wildlife Program
or the Environmental Protection
Agency’s 319 grant program, would
benefit the DPS if they do not alter
habitats known to be used by the DPS
beyond its tolerances and are
implemented with a primary objective
of improving environmental conditions
to support the aquatic biodiversity of
flowing water habitats. This provision of
the proposed 4(d) rule for other
activities would promote conservation
of the Upper Coosa River DPS by
excepting from the prohibition
incidental take resulting from activities
as described above (see proposed
§ 17.44(ee)(2)(iv)(C)).

Relation of 4(d) Rule to Available
Conservation Measures
Nothing in this proposed 4(d) rule
would 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 Upper Coosa River DPS. However,
interagency cooperation may be further
streamlined through planned
programmatic consultations for the
species between Federal agencies and
the Service, where appropriate. We ask
the public, particularly State agencies
and other interested stakeholders that
may be affected by the proposed 4(d)
rule, to provide comments and
suggestions regarding additional
guidance and methods that the Service
could provide or use, respectively, to
streamline the implementation of this
proposed 4(d) rule (see Information
Requested, above).
Since we are proposing a threatened
status for the Upper Coosa River DPS of
the frecklebelly madtom and this
proposed rule outlines the protections
in section 9(a)(1) of the Act for the DPS,
we are identifying those activities that
would or would not constitute a
violation of either section 9(a)(1) or this
proposed 4(d) rule. Based on the best
available information, at this time,
activities identified as discussed above
under Exceptions to Prohibitions would
not be considered to result in a violation
of section 9 of the Act. On the other
hand, based on the best available
information, the following actions may
potentially result in a violation of
section 9 of the Act if we adopt this
proposed rule; this list is not
comprehensive:
(1) Unauthorized handling, collecting,
possessing, selling, delivering, carrying,
or transporting of the frecklebelly
madtom, including interstate
transportation across State lines and
import or export across international
boundaries.
(2) Destruction/alteration of the
species’ habitat by discharge of fill
material, draining, ditching, tiling, pond
construction, stream channelization or
diversion, or diversion or alteration of
surface or ground water flow into or out
of the stream (i.e., due to roads,
impoundments, discharge pipes,
stormwater detention basins, etc.).
(3) Introduction of nonnative species
that compete with or prey upon the
frecklebelly madtom.
(4) Discharge of chemicals or fill
material into any waters in which the
frecklebelly madtom is known to occur.

III. Critical Habitat
Background
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
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
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
ownership or establish a refuge,
wilderness, reserve, preserve, or other
conservation area. Designation also does
not allow the government or public to
access private lands, nor does
designation require implementation of
restoration, recovery, or enhancement
measures by non-Federal landowners.
Where a landowner requests Federal
agency funding or authorization for an
action that may affect a listed species or
critical habitat, the Federal agency
would be required to consult with the
Service under section 7(a)(2) of the Act.
However, even if the Service were to
conclude that the proposed activity
would 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
and commercial data available, those
physical or biological features that are
essential to the conservation of the
species (such as space, food, cover, and
protected habitat). In identifying those
physical or biological features that occur
in specific occupied areas, we focus on
the specific features that are essential to
support the life-history needs of the
species, including, but not limited to,
water characteristics, soil type,
geological features, prey, vegetation,
symbiotic species, or other features. A
feature may be a single habitat
characteristic or a more complex
combination of habitat characteristics.
Features may include habitat
characteristics that support ephemeral
or dynamic habitat conditions. Features
may also be expressed in terms relating
to principles of conservation biology,
such as patch size, distribution
distances, and connectivity.
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. When designating critical
PO 00000
Frm 00025
Fmt 4701
Sfmt 4702
74073
habitat, the Secretary will first evaluate
areas occupied by the species. The
Secretary will only consider unoccupied
areas to be essential where a critical
habitat designation limited to
geographical areas occupied by the
species would be inadequate to ensure
the conservation of the species. In
addition, for an unoccupied area to be
considered essential, the Secretary must
determine that there is a reasonable
certainty both that the area will
contribute to the conservation of the
species and that the area contains one
or more of those physical or biological
features essential to 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.
When we are determining which areas
should be designated as critical habitat,
our primary source of information is
generally the information from the SSA
report and information developed
during the listing process for the
species. Additional information sources
may include any generalized
conservation strategy, criteria, or outline
that may have been developed for the
species; the recovery plan for the
species; articles in peer-reviewed
journals; conservation plans developed
by States and counties; scientific status
surveys and studies; biological
assessments; other unpublished
materials; or experts’ opinions or
personal knowledge.
Habitat is dynamic, and species may
move from one area to another over
time. We recognize that critical habitat
designated at a particular point in time
may not include all of the habitat areas
that we may later determine are
necessary for the recovery of the
species. For these reasons, a critical
habitat designation does not signal that
habitat outside the designated area is
unimportant or may not be needed for
E:\FR\FM\19NOP2.SGM
19NOP2
74074
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
recovery of the species. Areas that are
important to the conservation of the
species, both inside and outside the
critical habitat designation, will
continue to be subject to: (1)
Conservation actions implemented
under section 7(a)(1) of the Act; (2)
regulatory protections afforded by the
requirement in section 7(a)(2) of the Act
for Federal agencies to ensure their
actions are not likely to jeopardize the
continued existence of any endangered
or threatened species; and (3) section 9
of the Act’s prohibitions on taking any
individual of the species, including
taking caused by actions that affect
habitat. Federally funded or permitted
projects affecting listed species outside
their designated critical habitat areas
may still result in jeopardy findings in
some cases. These protections and
conservation tools will continue to
contribute to recovery of this species.
Similarly, critical habitat designations
made on the basis of the best available
information at the time of designation
will not control the direction and
substance of future recovery plans,
habitat conservation plans (HCPs), or
other species conservation planning
efforts if new information available at
the time of these planning efforts calls
for a different outcome.
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 or threatened species. Our
regulations (50 CFR 424.12(a)(1)) state
that the Secretary may, but is not
required to, determine that a
designation would not be prudent in the
following circumstances:
(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, or threats
to the species’ habitat stem solely from
causes that cannot be addressed through
management actions resulting from
consultations under section 7(a)(2) of
the Act;
(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;
(iv) No areas meet the definition of
critical habitat; or
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
(v) The Secretary otherwise
determines that designation of critical
habitat would not be prudent based on
the best scientific data available.
As discussed earlier in this document,
there is currently no imminent threat of
take attributed to collection or
vandalism identified under Factor B for
this species, and identification and
mapping of critical habitat is not
expected to initiate any such threat. In
our SSA and proposed listing
determination for the Upper Coosa River
DPS of the frecklebelly madtom, we
determined that the present or
threatened destruction, modification, or
curtailment of habitat or range is a
threat to the Upper Coosa River DPS and
that those threats in some way can be
addressed by section 7(a)(2)
consultation measures. The species
occurs wholly in the jurisdiction of the
United States, and we are able to
identify areas that meet the definition of
critical habitat. Therefore, because none
of the circumstances enumerated in our
regulations at 50 CFR 424.12(a)(1) have
been met and because there are no other
circumstances the Secretary has
identified for which this designation of
critical habitat would be not prudent,
we have determined that the
designation of critical habitat is prudent
for the Upper Coosa River DPS.
Critical Habitat Determinability
Having determined that designation is
prudent, under section 4(a)(3) of the Act
we must find whether critical habitat for
the Upper Coosa River DPS of the
frecklebelly madtom is determinable.
Our regulations at 50 CFR 424.12(a)(2)
state that critical habitat is not
determinable when one or both of the
following situations exist:
(i) Data sufficient to perform required
analyses are lacking, or
(ii) The biological needs of the species
are not sufficiently well known to
identify any area that meets the
definition of ‘‘critical habitat.’’ When
critical habitat is not determinable, the
Act allows the Service an additional
year to publish a critical habitat
designation (16 U.S.C. 1533(b)(6)(C)(ii)).
We reviewed the available
information pertaining to the biological
needs of the Upper Coosa River DPS and
habitat characteristics where this DPS is
located. This and other information
represent the best scientific data
available and led us to conclude that the
designation of critical habitat is
determinable for the Upper Coosa River
DPS.

In accordance with section 3(5)(A)(i)
of the Act and regulations at 50 CFR
424.12(b), in determining which areas
we will designate as critical habitat from
within the geographical area occupied
by the species at the time of listing, we
consider the physical or biological
features that are essential to the
conservation of the species and that may
require special management
considerations or protection. The
regulations at 50 CFR 424.02 define
‘‘physical or biological features essential
to the conservation of the species’’ as
the features that occur in specific areas
and that are essential to support the lifehistory needs of the species, including,
but not limited to, water characteristics,
soil type, geological features, sites, prey,
vegetation, symbiotic species, or other
features. A feature may be a single
habitat characteristic or a more complex
combination of habitat characteristics.
Features may include habitat
characteristics that support ephemeral
or dynamic habitat conditions. Features
may also be expressed in terms relating
to principles of conservation biology,
such as patch size, distribution
distances, and connectivity. For
example, physical features essential to
the conservation of the species might
include gravel of a particular size
required for spawning, alkali soil for
seed germination, protective cover for
migration, or susceptibility to flooding
or fire that maintains necessary earlysuccessional habitat characteristics.
Biological features might include prey
species, forage grasses, specific kinds or
ages of trees for roosting or nesting,
symbiotic fungi, or a particular level of
nonnative species consistent with
conservation needs of the listed species.
The features may also be combinations
of habitat characteristics and may
encompass the relationship between
characteristics or the necessary amount
of a characteristic essential to support
the life history of the species.
In considering whether features are
essential to the conservation of the
species, we may consider an appropriate
quality, quantity, and spatial and
temporal arrangement of habitat
characteristics in the context of the lifehistory needs, condition, and status of
the species. These characteristics
include, but are not limited to, space for
individual and population growth and
for normal behavior; food, water, air,
light, minerals, or other nutritional or
physiological requirements; cover or
shelter; sites for breeding, reproduction,
or rearing (or development) of offspring;

and habitats that are protected from
disturbance.
The Upper Coosa River DPS is a
population segment of the frecklebelly
madtom and occurs in the upper Coosa
River system in the Piedmont Upland
physiographic province in Georgia and
the Ridge and Valley physiographic
province in Georgia and Tennessee. The
primary habitat features that influence
the resiliency of the Upper Coosa River
DPS include flowing water, suitable
water quality, substrate, cover, and
habitat connectivity. These features are
essential to the survival and
reproduction of individuals at all life
stages.
As stated above, the frecklebelly
madtom occurs in small to large, swiftflowing rivers consisting of stable rifflerun pool complexes and with a substrate
that consists of silt-free gravel, coarse
sand, cobble, and boulders. The species
needs unimpounded flowing water to
successfully reproduce and maintain
populations. In addition, streams must
have an adequate flow to maintain
instream habitats and connectivity of
streams with the floodplain, which is
important to allow nutrient and
sediment exchange for habitat
maintenance. Stream reaches with
suitable habitat must be large enough
and have connectivity to support
enough frecklebelly madtoms to ensure
individuals can find a mate and
reproduce (Service 2020, p. 17). Cover is
an important component of suitable
habitat for the frecklebelly madtom and
provides shelter from predators, space
to forage, and space to nest. The species
is often found in or near aquatic
vegetation, such as river weed
(Podostemum spp.), woody structures,
and under large, flat rocks. In addition,
nesting sites for madtoms are typically
cavities under natural material (rocks,
logs, empty mussel shells). Thus, small
to large flowing rivers with appropriate
substrate, cover, and connectivity are
important for the growth, reproduction,
and survival of the frecklebelly madtom.
The frecklebelly madtom, like other
benthic species, is sensitive to poor
water quality (Warren et al. 1997, p.
125) and needs clean, flowing water to
survive. Changes in water chemistry and
flow patterns, resulting in a decrease in
water quality and quantity, have
detrimental effects on madtom ecology,
because they can render aquatic habitat
unsuitable for occupancy. In addition,
the frecklebelly madtom is intolerant of
excessive sedimentation (Shepard 2004,
p. 221). The minimum and maximum
standards of water quality and quantity
74075
conditions that are conducive to the
presence of frecklebelly madtom is not
well known. However, muddy
waterways, lentic streams (still water),
and poor water quality conditions are
not desirable for maintaining suitable
habitat for the species. Therefore,
appropriate water and sediment quality
are necessary to sustain growth,
reproduction, and viability of the
frecklebelly madtom and are essential to
the conservation of the species.
The species is an opportunistic
insectivore feeding on a variety of
aquatic insects and larvae, including
caddisflies, mayflies, blackflies, and
midges (Miller 1984, p. 9). Seasonal
changes found in diet probably reflect
differences in prey availability (Miller
1984, p. 11). Therefore, a diverse and
available aquatic macroinvertebrate
assemblage is important to the growth
and survival of the frecklebelly madtom.
More detail of the habitat and life
history needs are summarized above
under Background, and a thorough
review is available in the SSA report
(Service 2020, entire; available on
https://www.regulations.gov under
Docket No. FWS–R4–ES–2020–0058). A

Summary of Essential Physical or
Biological Features
We derive the specific physical or
biological features essential to the
conservation of Upper Coosa River DPS
of the frecklebelly madtom from studies
of the species’ habitat, ecology, and life
history as described above. Additional
information can be found in the SSA
report (Service 2020, entire; available on
https://www.regulations.gov under
Docket No. FWS–R4–ES–2020–0058).
We have determined that the following
physical or biological features are
essential to the conservation of Upper
Coosa River DPS of the frecklebelly
madtom:
(1) Geomorphically stable, medium to
large streams with:
VerDate Sep<11>2014

Jkt 253001
(a) Stable stream channels that
maintain lateral dimensions,
longitudinal profiles, and sinuosity
patterns over time without an aggrading
or degrading bed elevation; and
(b) Banks with intact riparian cover to
maintain stream morphology and reduce
erosion and sediment inputs.
(2) Connected instream habitats that:
(a) Include stable riffle-run pool
complexes;
(b) Consist of silt-free gravel, coarse
sand, cobble, boulders, woody structure,
and river weed (Podostemum spp.); and
(c) Have abundant cobble, boulders,
woody structure, or other suitable cover
used for nesting.
(3) Adequate flows, or a hydrologic
flow regime (which includes the
severity, frequency, duration, and
seasonality of discharge over time),

necessary to maintain instream habitats
and to maintain connectivity of streams
with the floodplain, allowing the
exchange of nutrients and sediment for
maintenance of the fish’s habitat, food
availability, and ample oxygenated flow
for spawning and nesting habitat.
(4) Appropriate water and sediment
quality (including, but not limited to,
conductivity; hardness; turbidity;
temperature; pH; ammonia; heavy
metals; pesticides; animal waste
products; and nitrogen, phosphorus,
and potassium fertilizers) necessary to
sustain natural physiological processes
for normal behavior, growth, and
viability of all life stages.
(5) Diversity and availability of
aquatic macroinvertebrate prey items,
which include larval midges, mayflies,
caddisflies, dragonflies, and beetles.

Special Management Considerations or
Protection
When designating critical habitat, we
assess whether the specific areas within
the geographical area occupied by the
species at the time of listing contain
features which are essential to the
conservation of the species and which
may require special management
considerations or protection. The
features essential to the conservation of
the Upper Coosa River DPS may require
special management considerations or
protections to reduce the following
threats: (1) Urbanization of the
landscape, including (but not limited to)
land conversion for urban and
commercial use, infrastructure (roads,
bridges, utilities), and urban water uses
(water supply reservoirs, wastewater
treatment); (2) nutrient pollution from
agricultural activities that impact water
quantity and quality; (3) significant
alteration of water quality; (4) culvert
and pipe installation that creates
barriers to movement; (5) other
watershed and floodplain disturbances
that release sediments or nutrients into
the water or fill suitable spawning
habitat; and (6) creation of reservoirs
that convert permanently flowing
streams and/or streams that hold water
into lake or pond-like (lentic)
environments.
Management activities that could
ameliorate these threats include, but are
not limited to, use of best management
practices (BMPs) designed to reduce
sedimentation, erosion, and bank-side
destruction; protection of riparian
corridors and suitable spawning habitat;
retention of sufficient canopy cover
along banks; moderation of surface and
ground water withdrawals to maintain
natural flow regimes; increased use of
stormwater management and reduction
of stormwater flows into the stream
systems; placement of culverts or
bridges that accommodate fish passage;
and reduction of other watershed and
floodplain disturbances that release
sediments, pollutants, or nutrients into
the water.
Criteria Used To Identify Critical
Habitat
As required by section 4(b)(2) of the
Act, we use the best scientific data
available to designate critical habitat. In
accordance with the Act and our
implementing regulations at 50 CFR
424.12(b), we review available
information pertaining to the habitat
requirements of the species and identify
specific areas within the geographical
area occupied by the species at the time
of listing and any specific areas outside
the geographical area occupied by the
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
species to be considered for designation
as critical habitat. To determine and
select appropriate occupied areas that
contain the physical or biological
features essential to the conservation of
the species or areas otherwise essential
for the conservation of the Upper Coosa
River DPS of the frecklebelly madtom,
we developed a conservation strategy
for the DPS. The goal of the
conservation strategy for the Upper
Coosa River DPS of the frecklebelly
madtom is to recover the DPS to the
point where the protections of the Act
are no longer necessary. The role of
critical habitat in achieving this
conservation goal is to identify the
specific areas within the Upper Coosa
River DPS’s range that provide essential
physical or biological features, without
which range-wide resiliency,
redundancy, and representation could
not be achieved. We anticipate that
recovery will require continued
protection of existing resilience units
and habitats that contribute to the
viability of the DPS, as well as ensuring
there are adequate numbers of fish in
stable units and that at least one viable
unit occurs in each of the physiographic
provinces (Piedmont Upland and Ridge
and Valley). This will help to ensure
that catastrophic events, such as floods,
cannot simultaneously affect all known
resilience units of the DPS. Recovery
considerations, such as maintaining
existing genetic diversity and striving
for representation of both physiographic
provinces in the DPS’s current range,
were considered in formulating this
proposal.
In developing our conservation
strategy for determining which areas to
include as critical habitat for the Upper
Coosa River DPS, we focused on the
existing resilience units and habitats
that are presently contributing to the
viability or historical units in which
resiliency can be improved such that
they contribute to viability of the
species. In summary, we identified
streams and rivers that are both: (1)
Currently occupied streams and rivers
within the known historical range of the
Upper Coosa River DPS, and (2) those
areas that have retained the physical or
biological features identified earlier that
will allow for the maintenance and
expansion of existing populations. For
the purposes of the proposed critical
habitat designation, and for areas within
the geographic area occupied by the
species at the time of listing, we
determined a unit to be occupied if it
contains a recent (i.e., observed in the
past 11 years (since 2009)) observation
(collection) or eDNA record that
supports the presence of the species.
PO 00000
Frm 00028
Fmt 4701
Sfmt 4702
Within those areas, we delineated
critical-habitat-unit boundaries using
the following process:
We evaluated habitat suitability of
stream and river channels within the
geographical area occupied at the time
of listing, and retained for further
consideration those streams that contain
one or more of the physical and
biological features to support lifehistory functions essential to
conservation of the Upper Coosa River
DPS. We determined the end points of
river units by evaluating the presence or
absence of appropriate physical and
biological features. Our upstream cutoff
points for each stream are located
approximately where the physiographic
province that the frecklebelly madtom
occupies begins (where the Conasauga
River flows out of the Blue Ridge and
into the Ridge and Valley physiographic
province and where the Etowah River
flows out of the Blue Ridge and into the
Piedmont Upland physiographic
province) and selected downstream
cutoff points that omit areas where
habitat conditions are less favorable for
the species (i.e., do not contain the
physical or biological features essential
to the conservation of the DPS).
Based on this analysis, the following
rivers meet criteria for areas occupied
by the species at the time of listing:
Conasauga River, Coosawattee River,
and Etowah River. These areas include
the two rivers, Conasauga River and
Etowah River, known to have been
occupied by the DPS historically.
Environmental DNA of the frecklebelly
madtom was detected in the Conasauga
River in 2017 and 2018, which meets
the criteria for consideration as an area
occupied by the species at the time of
listing. In the Etowah River, occurrence
data and eDNA records from 2018 are
available. These two areas meet our
conservation strategy for the frecklebelly
madtom. Designating critical habitat of
streams in these two occupied resilience
units of the DPS, which occur in both
physiographic provinces and currently
contribute to (or are historical units in
which resiliency can be improved to
contribute to) the species’ viability, will
sufficiently lead to the protection, and
eventual reduction in risk of extirpation,
of the DPS. Improving the resiliency of
the resilience units in these two
currently occupied streams will likely
increase viability to the point that the
protections of the Act are no longer
necessary.
The proposed designation does not
include the Coosawattee River, which is
not part of the known historical range of
the species. Environmental DNA of the
frecklebelly madtom was detected in the
Coosawattee River in 2018, which meets
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
the criteria for consideration as an area
occupied by the species at the time of
listing. However, since the Coosawattee
River is not part of the known historical
range of the frecklebelly madtom, this
area does not meet our conservation
strategy for designating critical habitat
for the species. The conservation
strategy focused on areas within the
historical known range of the species. In
addition, since the species has never
been directly observed in this river
despite multiple surveys over time,
using the best available information, we
determined this area is not a historical
unit in which resiliency can be
improved to contribute to the species’
viability. Lastly, we determined that
sufficient areas (Conasauga River and
Etowah River) already have been
identified within this proposed
designation. Should we receive
information during the public comment
period that supports designating as
critical habitat areas not included in the
proposed units (see Proposed Critical
Habitat Designation, below), we will
reevaluate our current proposal.
We are not currently proposing to
designate any areas outside the
geographical area occupied by the
Upper Coosa River DPS, because we
have not identified any unoccupied
areas that are essential for the
conservation of the species. The
protection of the Conasauga River and
Etowah River would sufficiently reduce
the risk of extinction, and improving the
resiliency of these currently occupied
streams of the DPS would increase
viability to the point that the protections
of the Act are no longer necessary.
Sources of data for this proposed
designation of critical habitat include
multiple databases maintained by
universities and State agencies in
Tennessee and Georgia, as well as
numerous survey reports on streams
throughout the DPS’s range. Other
sources of available information on
habitat requirements for this species
include studies conducted at occupied
sites and published in peer-reviewed
articles, agency reports, and data
collected during monitoring efforts
(Shepard et al. 1997, entire; Bennet et
al. 2008, entire; Bennet and Kuhajda
2010, entire; Albanese et al. 2018,
entire; Service 2020, entire).
Observation and eDNA records were
compiled and provided to us by State
partners during the SSA analysis.
When determining proposed critical
habitat boundaries, we made every
effort to avoid including developed
areas such as lands covered by
buildings, pavement, and other
structures because such lands lack
physical or biological features necessary
for the Upper Coosa River DPS. The
scale of the maps we prepared under the
parameters for publication within the
Code of Federal Regulations may not
reflect the exclusion of such developed
lands. Any such lands inadvertently left
inside critical habitat boundaries shown
on the maps of this proposed rule have
been excluded by text in the proposed
rule and are not proposed for
designation as critical habitat.
Therefore, if the critical habitat is
finalized as proposed, a Federal action
involving these lands would not trigger
section 7 consultation with respect to
critical habitat and the requirement of
no adverse modification unless the
specific action would affect the physical
or biological features in the adjacent
critical habitat.
We propose to designate as critical
habitat lands that we have determined
are occupied at the time of listing (i.e.,
currently occupied) and that contain
one or more of the physical or biological
features that are essential to support
life-history processes of the species.
Units are proposed for designation
based on one or more of the physical or
biological features being present to
support the Upper Coosa River DPS’s
life-history processes. Some units
contain all of the identified physical or
biological features and support multiple
life-history processes. Unit 1 contains
only some of the physical or biological
features necessary to support the Upper
Coosa River DPS’s particular use of that
habitat. Unit 2 contains all of the
74077
identified physical or biological features
and supports multiple life-history
processes.
The critical habitat designation is
defined by the map or maps, as
modified by any accompanying
regulatory text, presented at the end of
this document under Proposed
Regulation Promulgation. We include
more detailed information on the
boundaries of the critical habitat
designation in the preamble of this
document. We will make the
coordinates or plot points or both on
which each map is based available to
the public on https://
www.regulations.gov at Docket No.
FWS–R4–ES–2020–0058 and on our
internet site at https://www.fws.gov/
southeast/.
Proposed Critical Habitat Designation
We are proposing to designate
approximately 134 river miles (mi) (216
river kilometers (km)) in two units as
critical habitat for the Upper Coosa
River DPS of the frecklebelly madtom.
The critical habitat areas we describe
below constitute our current best
assessment of areas that meet the
definition of critical habitat for the
Upper Coosa River DPS. The two units
are: (1) Conasauga River Unit and (2)
Etowah River Unit. Table 4, below,
shows the proposed critical habitat
units, land ownership, and the
approximate river miles of each unit.
Per State regulations (Tennessee Code
Annotated section 69–1–101 and
Georgia Code section 52–1–31),
navigable waters are considered public
rights-of-way. Lands beneath the
navigable waters included in this
proposed rule are owned by the States
of Tennessee or Georgia. Ownership of
lands beneath nonnavigable waters
included in this rule are determined by
riparian land ownership. The riparian
land adjacent to the proposed critical
habitat is 85 percent private, 6 percent
local, 5 percent State, and 4 percent
Federal lands.

We present brief descriptions of all
units, and reasons why they meet the
definition of critical habitat for the
Upper Coosa River DPS, below.
Unit 1: Conasauga River
Unit 1 consists of approximately 51.5
river mi (83 km) of the Conasauga River
beginning at the mouth of Coahulla
Creek in Whitfield and Murray
Counties, Georgia, and continuing
upstream through Bradley County,
Tennessee, to the mouth of Graham
Branch in Polk County, Tennessee. Unit
1 includes river habitat up to bank full
height. Frecklebelly madtom occupies
all river reaches in this unit. Unit 1
contains some of the physical or
biological features necessary for the
conservation of the DPS. Unit 1
possesses those characteristics, as
described above under Summary of
Essential Physical or Biological
Features, of essential physical or
biological features (1), (2), (3), and (5).
Essential physical or biological feature
(4) is degraded in this unit, but with
appropriate management and restoration
actions, this physical or biological
feature can be restored.
Special management considerations
or protection may be required within
Unit 1 to alleviate impacts from
stressors that have led to the
degradation of the habitat, including
sedimentation, pollutant input, excess
nutrient input, development, and
unstable stream banks. Surrounding
land-use practices, including
agricultural runoff, agricultural
ditching, and erosion have led to high
levels of sedimentation, siltation,
contamination, and nutrient-loading, as
well as destabilized stream banks.
Special management considerations
related to agricultural and developed
areas that will benefit the habitat in this
unit include, but are not limited to,
riparian buffer restoration, reduced
surface and groundwater withdrawals,
increased open space in the watershed,
and treating wastewater to the highest
level practicable.
Unit 2: Etowah River
Unit 2 consists of approximately 82.5
river mi (133 km) of the Etowah River
beginning at its confluence with Shoal
Creek in Cherokee County, Georgia, and
continuing upstream through Forsyth
and Dawson Counties to approximately
0.5 miles upstream of the Jay Bridge
Road crossing over the Etowah River in
Lumpkin County, Georgia. Unit 2
includes river habitat up to bank full
height. Frecklebelly madtom occupies
all river reaches in this unit. Unit 2
contains all of the physical or biological
VerDate Sep<11>2014

Jkt 253001
features necessary for the conservation
of the DPS.
Special management considerations
or protection may be required within
Unit 2 to alleviate impacts from
stressors that are anticipated to amplify
degradation of the habitat, including
sedimentation, pollutant input, excess
nutrient input, development, and
unstable stream banks. Increased
development, including urban
development and runoff, dam
construction and use, and paved and
unpaved roads, in the surrounding
watershed and riparian area have led to
higher levels of sedimentation, siltation,
contamination, and nutrient-loading, as
well as destabilized stream banks.
Special management considerations
related to agricultural and developed
areas that will benefit the habitat in this
unit include, but are not limited to,
riparian buffer restoration, reduced
surface and groundwater withdrawals,
increased open space in the watershed,
and implementing highest levels of
treatment of wastewater practicable.
Effects of Critical Habitat Designation
Section 7 Consultation
Section 7(a)(2) of the Act requires
Federal agencies, including the Service,
to ensure that any action they fund,
authorize, 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. In
addition, section 7(a)(4) of the Act
requires Federal agencies to confer with
the Service on any agency action which
is likely to jeopardize the continued
existence of any species proposed to be
listed under the Act or result in the
destruction or adverse modification of
proposed critical habitat.
We published a final rule revising the
definition of destruction or adverse
modification on August 27, 2019 (84 FR
44976). Destruction or adverse
modification means a direct or indirect
alteration that appreciably diminishes
the value of critical habitat as a whole
for the conservation of a listed species.
If a Federal action may affect a listed
species or its critical habitat, the
responsible Federal agency (action
agency) must enter into consultation
with us. Examples of actions that are
subject to the section 7 consultation
process are 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 section 10 of the Act) or
PO 00000
Frm 00030
Fmt 4701
Sfmt 4702
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.
Compliance with the requirements of
section 7(a)(2) is documented through
our issuance of:
(1) A concurrence letter for Federal
actions that may affect, but are not
likely to adversely affect, listed species
or critical habitat; or
(2) A biological opinion for Federal
actions that may affect, and are likely to
adversely affect, listed species or critical
habitat.
When we issue a biological opinion
concluding that a project is likely to
jeopardize the continued existence of a
listed species and/or destroy or
adversely modify critical habitat, we
provide reasonable and prudent
alternatives to the project, if any are
identifiable, that would avoid the
likelihood of jeopardy and/or
destruction or adverse modification of
critical habitat. We define ‘‘reasonable
and prudent alternatives’’ (at 50 CFR
402.02) as alternative actions identified
during consultation that:
(1) Can be implemented in a manner
consistent with the intended purpose of
the action,
(2) Can be implemented consistent
with the scope of the Federal agency’s
legal authority and jurisdiction,
(3) Are economically and
technologically feasible, and
(4) Would, in the Service Director’s
opinion, avoid the likelihood of
jeopardizing the continued existence of
the listed species and/or avoid the
likelihood of destroying or adversely
modifying critical habitat.
Reasonable and prudent alternatives
can vary from slight project
modifications to extensive redesign or
relocation of the project. Costs
associated with implementing a
reasonable and prudent alternative are
similarly variable.
Regulations at 50 CFR 402.16 set forth
requirements for Federal agencies to
reinitiate formal consultation on
previously reviewed actions. These
requirements apply when the Federal
agency has retained discretionary
involvement or control over the action
(or the agency’s discretionary
involvement or control is authorized by
law) and, subsequent to the previous
consultation, we have listed a new
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
species or designated critical habitat
that may be affected by the Federal
action, or the action has been modified
in a manner that affects the species or
critical habitat in a way not considered
in the previous consultation. In such
situations, Federal agencies sometimes
may need to request reinitiation of
consultation with us, but the regulations
also specify some exceptions to the
requirement to reinitiate consultation on
specific land management plans after
subsequently listing a new species or
designating new critical habitat. See the
regulations for a description of those
exceptions.
Application of the ‘‘Destruction or
Adverse Modification’’ Standard
The key factor related to the
destruction or adverse modification
determination is whether
implementation of the proposed Federal
action directly or indirectly alters the
designated critical habitat in a way that
appreciably diminishes the value of the
critical habitat as a whole for the
conservation of the listed species. As
discussed above, the role of critical
habitat is to support physical or
biological features essential to the
conservation of a listed species and
provide for the conservation of the
species.
Section 4(b)(8) of the Act requires us
to briefly evaluate and describe, in any
proposed or final regulation that
designates critical habitat, activities
involving a Federal action that may
violate section 7(a)(2) of the Act by
destroying or adversely modifying such
habitat, or that may be affected by such
designation.
Activities that the Service may,
during a consultation under section
7(a)(2) of the Act, find are likely to
destroy or adversely modify critical
habitat include, but are not limited to:
(1) Actions that would alter the
minimum flow or existing flow regime.
Such activities could include, but are
not limited to, impoundment,
channelization, water diversion, water
withdrawal, hydropower generation,
and flood control. These activities could
eliminate or reduce the habitat
necessary for the growth and
reproduction of the Upper Coosa River
DPS by altering flows to levels that
would adversely affect the Upper Coosa
River DPS’s ability to complete its life
cycle.
(2) Actions that would significantly
alter water chemistry or quality. Such
activities could include, but are not
limited to, release of chemicals or
biological pollutants into the surface
water or connected groundwater at a
point source or by dispersed release

Jkt 253001
(non-point source). These activities
could alter water conditions to levels
that are beyond the tolerances of the
Upper Coosa River DPS and result in
direct or cumulative adverse effects to
individuals and their life cycles.
(3) Actions that would significantly
increase sediment deposition within the
stream channel. Such activities could
include, but are not limited to, excessive
sedimentation from livestock grazing,
road construction, channel alteration,
and other watershed and floodplain
disturbances. These activities could
eliminate or reduce the habitat
necessary for the growth and
reproduction of the Upper Coosa River
DPS by increasing the sediment
deposition to levels that would
adversely affect the DPS’s ability to
complete its life cycle.
(4) Actions that would significantly
increase eutrophication (the addition of
excessive nutrients that are typically
limited in aquatic environments, such
as nitrogen and phosphorus that cause
phytoplankton to proliferate). Such
activities could include, but are not
limited to, release of excessive nutrients
into the surface water or connected
groundwater at a point source or by
dispersed release (non-point source).
These activities could result in
excessive nutrients and algae filling
streams and reducing habitat, degrading
water quality from excessive nutrients
and algae decay, and decreasing oxygen
levels below the tolerances of the DPS.
(5) Actions that would significantly
alter channel morphology or geometry,
or decrease connectivity. Such activities
could include, but are not limited to,
channelization, impoundment, road and
bridge construction, mining, dredging,
and destruction of riparian vegetation.
These activities may lead to changes in
water flows and levels that would
degrade or eliminate the Upper Coosa
River DPS and its habitats. These
actions could also lead to increased
sedimentation and degradation in water
quality to levels beyond the tolerances
of the DPS.
(6) Actions that result in the
introduction, spread, or augmentation of
nonnative aquatic species in occupied
stream segments, or in stream segments
that are hydrologically connected to
occupied stream segments, or
introduction of other species that
compete with or prey on the Upper
Coosa River DPS. Possible actions could
include, but are not limited to, stocking
of nonnative fishes and crayfishes, or
other related actions. These activities
could introduce parasites or disease;
result in direct predation or direct
competition; or affect the growth,
reproduction, and survival of the DPS.

Exemptions
Application of Section 4(a)(3) of the Act
Section 4(a)(3)(B)(i) of the Act (16
U.S.C. 1533(a)(3)(B)(i)) provides that the
Secretary shall not designate as critical
habitat any lands or other geographical
areas owned or controlled by the
Department of Defense, or designated
for its use, that are subject to an
integrated natural resources
management plan (INRMP) prepared
under section 101 of the Sikes Act (16
U.S.C. 670a), if the Secretary determines
in writing that such plan provides a
benefit to the species for which critical
habitat is proposed for designation.
There are no Department of Defense
(DoD) lands within the proposed critical
habitat designation.
Consideration of Impacts Under Section
4(b)(2) of the Act
Section 4(b)(2) of the Act states that
the Secretary shall designate and make
revisions to critical habitat on the basis
of the best available scientific data after
taking into consideration the economic
impact, national security impact, and
any other relevant impact of specifying
any particular area as critical habitat.
The Secretary may exclude an area from
critical habitat if he determines that the
benefits of such exclusion outweigh the
benefits of specifying such area as part
of the critical habitat, unless he
determines, based on the best scientific
data available, that the failure to
designate such area as critical habitat
will result in the extinction of the
species. In making the determination to
exclude a particular area, the statute on
its face, as well as the legislative history,
are clear that the Secretary has broad
discretion regarding which factor(s) to
use and how much weight to give to any
factor.
The first sentence in section 4(b)(2) of
the Act requires that we take into
consideration the economic, national
security, or other relevant impacts of
designating any particular area as
critical habitat. We describe below the
process that we undertook for taking
into consideration each category of
impacts and our analyses of the relevant
impacts.
Consideration of Economic Impacts
Section 4(b)(2) of the Act and its
implementing regulations require that
we consider the economic impact that
may result from a designation of critical
habitat. To assess the probable
economic impacts of a designation, we
must first evaluate specific land uses or
activities and projects that may occur in
the area of the critical habitat. We then
must evaluate the impacts that a specific
E:\FR\FM\19NOP2.SGM
19NOP2
74080
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
critical habitat designation may have on
restricting or modifying specific land
uses or activities for the benefit of the
species and its habitat within the areas
proposed. We then identify which
conservation efforts may be the result of
the species being listed under the Act
versus those attributed solely to the
designation of critical habitat for this
particular species. The probable
economic impact of a proposed critical
habitat designation is analyzed by
comparing scenarios both ‘‘with critical
habitat’’ and ‘‘without critical habitat.’’
The ‘‘without critical habitat’’
scenario represents the baseline for the
analysis, which includes the existing
regulatory and socio-economic burden
imposed on landowners, managers, or
other resource users potentially affected
by the designation of critical habitat
(e.g., under the Federal listing as well as
other Federal, State, and local
regulations). The baseline, therefore,
represents the costs of all efforts
attributable to the listing of the species
under the Act (i.e., conservation of the
species and its habitat incurred
regardless of whether critical habitat is
designated). The ‘‘with critical habitat’’
scenario describes the incremental
impacts associated specifically with the
designation of critical habitat for the
species. The incremental conservation
efforts and associated impacts would
not be expected without the designation
of critical habitat for the species. In
other words, the incremental costs are
those attributable solely to the
designation of critical habitat, above and
beyond the baseline costs. These are the
costs we use when evaluating the
benefits of inclusion and exclusion of
particular areas from the final
designation of critical habitat should we
choose to conduct a discretionary
4(b)(2) exclusion analysis.
For this designation, we developed an
incremental effects memorandum (IEM)
considering the probable incremental
economic impacts that may result from
the proposed designation. The
information contained in our IEM was
then used to develop a screening
analysis of the probable effects of the
designation (IEc 2020, entire). The
purpose of the screening analysis is to
filter out particular geographic areas of
critical habitat that are already subject
to such protections and are, therefore,
unlikely to incur incremental economic
impacts. In particular, the screening
analysis considers baseline costs (i.e.,
absent critical habitat designation) and
includes probable economic impacts
where land and water use may be
subject to conservation plans, land
management plans, best management
practices, or regulations that protect the
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
habitat area as a result of the Federal
listing status of the Upper Coosa River
DPS. Ultimately, the screening analysis
allows us to focus on evaluating the
specific areas or sectors that may incur
probable incremental economic impacts
as a result of the designation. This
screening analysis, combined with the
information contained in our IEM,
comprises our draft economic analysis
(DEA) of the proposed critical habitat
designation for the Upper Coosa River
DPS of the frecklebelly madtom; our
DEA is summarized in the narrative
below.
Executive Orders (E.O.s) 12866 and
13563 direct Federal agencies to assess
the costs and benefits of available
regulatory alternatives in quantitative
(to the extent feasible) and qualitative
terms. Consistent with the E.O.
regulatory analysis requirements, our
effects analysis under the Act may take
into consideration impacts to both
directly and indirectly affected entities,
where practicable and reasonable. If
sufficient data are available, we assess
to the extent practicable the probable
impacts to both directly and indirectly
affected entities. As part of our
screening analysis, we considered the
types of economic activities that are
likely to occur within the areas likely
affected by the critical habitat
designation. In our evaluation of the
probable incremental economic impacts
that may result from the proposed
designation of critical habitat for the
Upper Coosa River DPS, first we
identified, in the IEM dated June 23,
2020, probable incremental economic
impacts associated with the following
categories of activities: (1) Federal lands
management (U.S. Forest Service and
U.S. Army Corps of Engineers); (2)
agriculture; (3) development; (4)
roadway and bridgeway construction;
(5) dredging, dams, and diversions; (6)
flood control and hydropower; (7)
wastewater and chemical discharge; (8)
pesticide use; (9) recreation; (10)
conservation and restoration; and (11)
transportation and utilities. We
considered each industry or category
individually. Additionally, we
considered whether these activities have
any Federal involvement. Critical
habitat designation generally will not
affect activities that do not have any
Federal involvement; under the Act,
designation of critical habitat only
affects activities conducted, funded,
permitted, or authorized by Federal
agencies. In areas where individuals
from the Upper Coosa River DPS are
found, Federal agencies already are
required to ensure that their actions are
not likely to jeopardize the continued
PO 00000
Frm 00032
Fmt 4701
Sfmt 4702
existence of the DPS under section 7
consultation procedures. If we finalize
this proposed critical habitat
designation, consultations to avoid the
destruction or adverse modification of
critical habitat would be incorporated
into the existing consultation process.
In our IEM, we attempted to clarify
the distinction between the effects that
will result from the species being listed
and those attributable to the critical
habitat designation (i.e., difference
between the jeopardy and adverse
modification standards) for the Upper
Coosa River DPS’s critical habitat.
Because the designation of critical
habitat for the Upper Coosa River DPS
was proposed concurrently with the
listing, it has been our experience that
it is more difficult to discern which
conservation efforts are attributable to
the species being listed and those which
will result solely from the designation of
critical habitat. However, the following
specific circumstances in this case help
to inform our evaluation: (1) The
essential physical or biological features
identified for critical habitat are the
same features essential for the life
requisites of the species, and (2) any
actions that would result in sufficient
harm or harassment to constitute
jeopardy to the Upper Coosa River DPS
would also likely adversely affect the
essential physical or biological features
of critical habitat. The IEM outlines our
rationale concerning this limited
distinction between baseline
conservation efforts and incremental
impacts of the designation of critical
habitat for this species. This evaluation
of the incremental effects has been used
as the basis to evaluate the probable
incremental economic impacts of this
proposed designation of critical habitat.
The proposed critical habitat
designation for the Upper Coosa River
DPS totals approximately 134 river
miles (mi) (216 river kilometers (km)) in
two occupied units in Georgia and
Tennessee. In these areas, any actions
that may affect the species would also
affect proposed critical habitat because
all designated habitat is occupied. Thus,
it is unlikely that any additional
conservation efforts would be
recommended to address the adverse
modification standard over and above
those recommended as necessary to
avoid jeopardizing the continued
existence of the Upper Coosa River DPS.
Therefore, the only additional costs that
are expected in all of the proposed
critical habitat designation are
administrative costs. These costs are
due to additional consultation analysis
requiring time and resources by both the
Federal action agency and the Service.
However, these costs are not expected to
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
reach the threshold of ‘‘significant’’
under E.O. 12866. We anticipate a
maximum of 10 section 7 consultations
annually at a total incremental cost of
less than $11,000 per year.
We are soliciting data and comments
from the public on the DEA discussed
above, as well as all aspects of this
proposed rule and our required
determinations. During the development
of a final designation, we will consider
the information presented in the DEA
and any additional information on
economic impacts received during the
public comment period to determine
whether any specific areas should be
excluded from the final critical habitat
designation under authority of section
4(b)(2) and our implementing
regulations at 50 CFR 424.19. In
particular, we may exclude an area from
critical habitat if we determine that the
benefits of excluding the area outweigh
the benefits of including the area,
provided the exclusion will not result in
the extinction of this species.
The final decision on whether to
exclude any areas will be based on the
best scientific data available at the time
of the final designation, including
information we obtain during the public
comment period and information about
the economic impact of designation.
Accordingly, we have prepared a draft
economic analysis concerning the
proposed critical habitat designation,
which is available for review and
comment (see ADDRESSES).
Consideration of National Security
Impacts
In preparing this proposal, we have
determined that the lands within the
proposed designation of critical habitat
for the Upper Coosa River DPS are not
owned, managed, or used by the DoD or
DHS where a national security or
homeland security impact might exist,
and, therefore, we anticipate no impact
on national security or homeland
security. However, during the
development of a final designation, we
will consider any additional
information received through the public
comment period on the impacts of the
proposed designation on national
security or homeland security to
determine whether any specific areas
should be excluded from the final
critical habitat designation under
authority of section 4(b)(2) and our
implementing regulations at 50 CFR
424.19.
Consideration of Other Relevant
Impacts
We consider a number of factors,
including whether there are permitted
conservation plans covering the species
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
in the area such as HCPs, safe harbor
agreements (SHAs), or candidate
conservation agreements with
assurances (CCAAs), or whether there
are non-permitted conservation
agreements and partnerships that would
be encouraged by designation of, or
exclusion from, critical habitat. In
addition, we look at the existence of
Tribal conservation plans and
partnerships and consider the
government-to-government relationship
of the United States with Tribal entities.
We also consider any social impacts that
might occur because of the designation.
In preparing this proposal, we have
determined that there are currently no
draft or final HCPs or other management
plans for the Upper Coosa River DPS,
and the proposed designation does not
include any Tribal lands or trust
resources.
As discussed above, we anticipate no
impacts on national security, economic,
or any other relevant impacts as a result
of this designation. Accordingly, at this
time, we do not propose to exclude any
particular areas from the critical habitat
designation. However, during the
development of a final designation, we
will consider any additional
information we receive through the
public comment period regarding other
relevant impacts to determine whether
any specific areas should be excluded
from the final critical habitat
designation under authority of section
4(b)(2) and our implementing
regulations at 50 CFR 424.19.
Required Determinations
Clarity of the Rule
We are required by Executive Orders
12866 and 12988 and by the
Presidential Memorandum of June 1,
1998, to write all rules in plain
language. This means that each rule we
publish must:
(1) Be logically organized;
(2) Use the active voice to address
readers directly;
(3) Use clear language rather than
jargon;
(4) Be divided into short sections and
sentences; and
(5) Use lists and tables wherever
possible.
If you feel that we have not met these
requirements, send us comments by one
of the methods listed in ADDRESSES. To
better help us revise the rule, your
comments should be as specific as
possible. For example, you should tell
us the numbers of the sections or
paragraphs that are unclearly written,
which sections or sentences are too
long, the sections where you feel lists or
tables would be useful, etc.

Regulatory Planning and Review
(Executive Orders 12866 and 13563)
Executive Order 12866 provides that
the Office of Information and Regulatory
Affairs (OIRA) in the Office of
Management and Budget will review all
significant rules. OIRA has determined
that this rule is not significant.
Executive Order 13563 reaffirms the
principles of E.O. 12866 while calling
for improvements in the nation’s
regulatory system to promote
predictability, to reduce uncertainty,
and to use the best, most innovative,
and least burdensome tools for
achieving regulatory ends. The
executive order directs agencies to
consider regulatory approaches that
reduce burdens and maintain flexibility
and freedom of choice for the public
where these approaches are relevant,
feasible, and consistent with regulatory
objectives. E.O. 13563 emphasizes
further that regulations must be based
on the best available science and that
the rulemaking process must allow for
public participation and an open
exchange of ideas. We have developed
this proposed rule in a manner
consistent with these requirements.
Regulatory Flexibility Act (5 U.S.C. 601
et seq.)
Under the Regulatory Flexibility Act
(RFA; 5 U.S.C. 601 et seq.), as amended
by the Small Business Regulatory
Enforcement Fairness Act of 1996
(SBREFA; 5 U.S.C. 801 et seq.),
whenever an agency is required to
publish a notice of rulemaking for any
proposed or final rule, it must prepare
and make available for public comment
a regulatory flexibility analysis that
describes the effects of the rule on small
entities (i.e., small businesses, small
organizations, and small government
jurisdictions). However, no regulatory
flexibility analysis is required if the
head of the agency certifies the rule will
not have a significant economic impact
on a substantial number of small
entities. The SBREFA amended the RFA
to require Federal agencies to provide a
certification statement of the factual
basis for certifying that the rule will not
have a significant economic impact on
a substantial number of small entities.
According to the Small Business
Administration, small entities include
small organizations such as
independent nonprofit organizations;
small governmental jurisdictions,
including school boards and city and
town governments that serve fewer than
50,000 residents; and small businesses
(13 CFR 121.201). Small businesses
include manufacturing and mining
concerns with fewer than 500
E:\FR\FM\19NOP2.SGM
19NOP2
74082
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
employees, wholesale trade entities
with fewer than 100 employees, retail
and service businesses with less than $5
million in annual sales, general and
heavy construction businesses with less
than $27.5 million in annual business,
special trade contractors doing less than
$11.5 million in annual business, and
agricultural businesses with annual
sales less than $750,000. To determine
whether potential economic impacts to
these small entities are significant, we
considered the types of activities that
might trigger regulatory impacts under
this designation as well as types of
project modifications that may result. In
general, the term ‘‘significant economic
impact’’ is meant to apply to a typical
small business firm’s business
operations.
Under the RFA, as amended, and as
understood in the light of recent court
decisions, Federal agencies are required
to evaluate the potential incremental
impacts of rulemaking only on those
entities directly regulated by the
rulemaking itself and, therefore, are not
required to evaluate the potential
impacts to indirectly regulated entities.
The regulatory mechanism through
which critical habitat protections are
realized is section 7 of the Act, which
requires Federal agencies, in
consultation with the Service, to ensure
that any action authorized, funded, or
carried out by the agency is not likely
to destroy or adversely modify critical
habitat. Therefore, under section 7, only
Federal action agencies are directly
subject to the specific regulatory
requirement (avoiding destruction and
adverse modification) imposed by
critical habitat designation.
Consequently, it is our position that
only Federal action agencies would be
directly regulated if we adopt the
proposed critical habitat designation.
There is no requirement under the RFA
to evaluate the potential impacts to
entities not directly regulated.
Moreover, Federal agencies are not
small entities. Therefore, because no
small entities would be directly
regulated by this rulemaking, the
Service certifies that, if made final as
proposed, the proposed critical habitat
designation will not have a significant
economic impact on a substantial
number of small entities.
In summary, we have considered
whether the proposed designation
would result in a significant economic
impact on a substantial number of small
entities. For the above reasons and
based on currently available
information, we certify that, if made
final, the proposed critical habitat
designation will not have a significant
economic impact on a substantial
VerDate Sep<11>2014
21:38 Nov 18, 2020
Jkt 253001
number of small business entities.
Therefore, an initial regulatory
flexibility analysis is not required.
Executive Order 13771
This proposed rule is not a regulatory
action subject to Executive Order (E.O.)
13771 (‘‘Reducing Regulation and
Controlling Regulatory Costs’’) (82 FR
9339, February 3, 2017) regulatory
action because this rule is not
significant under E.O. 12866.
Energy Supply, Distribution, or Use—
Executive Order 13211
Executive Order 13211 (Actions
Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use) requires agencies
to prepare Statements of Energy Effects
when undertaking certain actions. The
Office of Management and Budget
(OMB) provides guidance for
implementing this Executive Order,
outlining nine outcomes (criteria) that
may constitute ‘‘a significant adverse
effect’’ when compared with the
regulatory action under consideration.
The economic analysis finds that none
of these criteria are relevant to this
analysis, and therefore, we did not find
that this proposed critical habitat
designation would significantly affect
energy supplies, distribution, or use.
Therefore, this action is not a significant
energy action, and no Statement of
Energy Effects is required.
Unfunded Mandates Reform Act (2
U.S.C. 1501 et seq.)
In accordance with the Unfunded
Mandates Reform Act (2 U.S.C. 1501 et
seq.), we make the following finding:
(1) This proposed rule would not
produce a Federal mandate. In general,
a Federal mandate is a provision in
legislation, statute, or regulation that
would impose an enforceable duty upon
State, local, or Tribal governments, or
the private sector, and includes both
‘‘Federal intergovernmental mandates’’
and ‘‘Federal private sector mandates.’’
These terms are defined in 2 U.S.C.
658(5)–(7). ‘‘Federal intergovernmental
mandate’’ includes a regulation that
‘‘would impose an enforceable duty
upon State, local, or tribal governments’’
with two exceptions. It excludes ‘‘a
condition of Federal assistance.’’ It also
excludes ‘‘a duty arising from
participation in a voluntary Federal
program,’’ unless the regulation ‘‘relates
to a then-existing Federal program
under which $500,000,000 or more is
provided annually to State, local, and
tribal governments under entitlement
authority,’’ if the provision would
‘‘increase the stringency of conditions of
assistance’’ or ‘‘place caps upon, or
PO 00000
Frm 00034
Fmt 4701
Sfmt 4702
otherwise decrease, the Federal
Government’s responsibility to provide
funding,’’ and the State, local, or Tribal
governments ‘‘lack authority’’ to adjust
accordingly. At the time of enactment,
these entitlement programs were:
Medicaid; Aid to Families with
Dependent Children work programs;
Child Nutrition; Food Stamps; Social
Services Block Grants; Vocational
Rehabilitation State Grants; Foster Care,
Adoption Assistance, and Independent
Living; Family Support Welfare
Services; and Child Support
Enforcement. ‘‘Federal private sector
mandate’’ includes a regulation that
‘‘would impose an enforceable duty
upon the private sector, except (i) a
condition of Federal assistance or (ii) a
duty arising from participation in a
voluntary Federal program.’’
The designation of critical habitat
does not impose a legally binding duty
on non-Federal Government entities or
private parties. Under the Act, the only
regulatory effect is that Federal agencies
must ensure that their actions do not
destroy or adversely modify critical
habitat under section 7. While nonFederal entities that receive Federal
funding, assistance, or permits, or that
otherwise require approval or
authorization from a Federal agency for
an action, may be indirectly impacted
by the designation of critical habitat, the
legally binding duty to avoid
destruction or adverse modification of
critical habitat rests squarely on the
Federal agency. Furthermore, to the
extent that non-Federal entities are
indirectly impacted because they
receive Federal assistance or participate
in a voluntary Federal aid program, the
Unfunded Mandates Reform Act would
not apply, nor would critical habitat
shift the costs of the large entitlement
programs listed above onto State
governments.
(2) We do not believe that this rule
would significantly or uniquely affect
small governments, because it will not
produce a Federal mandate of $100
million or greater in any year, that is, it
is not a ‘‘significant regulatory action’’
under the Unfunded Mandates Reform
Act. The designation of critical habitat
imposes no obligations on State or local
governments and, as such, a Small
Government Agency Plan is not
required.
Takings—Executive Order 12630
In accordance with E.O. 12630
(Government Actions and Interference
with Constitutionally Protected Private
Property Rights), we have analyzed the
potential takings implications of
designating critical habitat for Upper
Coosa River DPS in a takings
E:\FR\FM\19NOP2.SGM
19NOP2
Federal Register / Vol. 85, No. 224 / Thursday, November 19, 2020 / Proposed Rules
implications assessment. The Act does
not authorize the Service to regulate
private actions on private lands or
confiscate private property as a result of
critical habitat designation. Designation
of critical habitat does not affect land
ownership, or establish any closures, or
restrictions on use of or access to the
designated areas. Furthermore, the
designation of critical habitat does not
affect landowner actions that do not
require Federal funding or permits, nor
does it preclude development of habitat
conservation programs or issuance of
incidental take permits to permit actions
that do require Federal funding or
permits to go forward. However, Federal
agencies are prohibited from carrying
out, funding, or authorizing actions that
would destroy or adversely modify
critical habitat. A takings implications
assessment has been completed for the
proposed designation of critical habitat
for Upper Coosa River DPS, and it
concludes that, if adopted, this
designation of critical habitat does not
pose significant takings implications for
lands within or affected by the
designation.
Federalism—Executive Order 13132
In accordance with E.O. 13132
(Federalism), this proposed rule does
not have significant Federalism effects.
A federalism summary impact statement
is not required. In keeping with
Department of the Interior and
Department of Commerce policy, we
requested information from, and
coordinated development of this
proposed critical habitat designation
with, appropriate State resource
agencies. From a federalism perspective,
the designation of critical habitat
directly affects only the responsibilities
of Federal agencies. The Act imposes no
other duties with respect to critical
habitat, either for States and local
governments, or for anyone else. As a
result, the proposed rule does not have
substantial direct effects either on the
States, or on the relationship between
the national government and the States,
or on the distribution of powers and
responsibilities among the various
levels of government. The proposed
designation may have some benefit to
these governments because the areas
that contain the features essential to the
conservation of the species are more
clearly defined, and the physical or
biological features of the habitat
necessary for the conservation of the
species are specifically identified. This
information does not alter where and
what federally sponsored activities may

wait for case-by-case section 7
consultations to occur.
Where State and local governments
require approval or authorization from a
Federal agency for actions that may
affect critical habitat, consultation
under section 7(a)(2) of the Act would
be required. While non-Federal entities
that receive Federal funding, assistance,
or permits, or that otherwise require
approval or authorization from a Federal
agency for an action, may be indirectly
impacted by the designation of critical
habitat, the legally binding duty to
avoid destruction or adverse
modification of critical habitat rests
squarely on the Federal agency.
Civil Justice Reform—Executive Order
12988
In accordance with Executive Order
12988 (Civil Justice Reform), the Office
of the Solicitor has determined that the
rule would not unduly burden the
judicial system and that it meets the
requirements of sections 3(a) and 3(b)(2)
of the Order. We have proposed
designating critical habitat in
accordance with the provisions of the
Act. To assist the public in
understanding the habitat needs of the
species, this proposed rule identifies the
elements of physical or biological
features essential to the conservation of
the species. The proposed areas of
designated critical habitat are presented
on maps, and the proposed rule
provides several options for the
interested public to obtain more
detailed location information, if desired.
Paperwork Reduction Act of 1995 (44
U.S.C. 3501 et seq.)
This rule does not contain
information collection requirements,
and a submission to the Office of
Management and Budget (OMB) under
the Paperwork Reduction Act of 1995
(44 U.S.C. 3501 et seq.) is not required.
We may not conduct or sponsor, and
you are not required to respond to, a
collection of information unless it
displays a currently valid OMB control
number.
National Environmental Policy Act (42
U.S.C. 4321 et seq.)
We have determined that
environmental assessments and
environmental impact statements, as
defined under the authority of the
National Environmental Policy Act
(NEPA), need not be prepared in
connection with listing a species as an
endangered or threatened species under
the Act. We published a notice outlining
our reasons for this determination in the
Federal Register on October 25, 1983
(48 FR 49244).

It is also our position that, outside the

for the Tenth Circuit, we do not need to
prepare environmental analyses
pursuant to the NEPA in connection
with designating critical habitat under
the Act. We published a notice outlining
our reasons for this determination in the
Federal Register on October 25, 1983
(48 FR 49244). This position was upheld
by the U.S. Court of Appeals for the
Ninth Circuit (Douglas County v.

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
Governments), and the Department of
the Interior’s manual at 512 DM 2, we
readily acknowledge our responsibility
to communicate meaningfully with
recognized Federal Tribes on a
government-to-government basis. In
accordance with Secretarial 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.
We have identified no Tribal interests
that would be affected by this proposed
listing. We have also determined that no
Tribal lands fall within the boundaries
of the proposed critical habitat for the
Upper Coosa River DPS, so no Tribal
lands would be affected by the proposed
designation.

projects can be accomplished using a
variety of methods, but the desired
outcome is a natural channel with
geomorphically stable stream channels
that maintain the appropriate lateral

sinuosity patterns over time without an
aggrading or degrading bed elevation
and include stable riffle-run-pool
complexes that consist of silt-free
gravel, coarse sand, cobble, boulders,
woody structure, and river weed
(Podostemum spp.).
(B) Streambank stabilization projects
that use bioengineering methods to
replace pre-existing, bare, eroding
stream banks with natively vegetated,
stable stream banks, thereby reducing
bank erosion and instream
sedimentation and improving habitat
conditions for the DPS. Stream banks
may be stabilized using live stakes (live,
vegetative cuttings inserted or tamped
into the ground in a manner that allows
the stake to take root and grow), live
fascines (live branch cuttings, usually
willows, bound together into long, cigarshaped bundles), or brush layering
(cuttings or branches of easily rooted
tree species layered between successive
lifts of soil fill). Stream banks must not
be stabilized solely through the use of
quarried rock (rip-rap) or the use of rock
baskets or gabion structures.

Population Segment of Frecklebelly Madtom and Designation of Critical
Habitat
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce a
12-month finding on a petition to list the frecklebelly madtom (Noturus
munitus), a fish species from Louisiana, Mississippi, Alabama, Georgia,
and Tennessee, as an endangered or threatened species and designate
critical habitat under the Endangered Species Act of 1973, as amended
(Act). After a review of the best available scientific and commercial
information, we find that listing the frecklebelly madtom as an
endangered or a threatened species throughout all of its range is not
warranted. However, we determined that listing is warranted for a
distinct population segment (DPS) of the frecklebelly madtom in the
Upper Coosa River in Georgia and Tennessee. Accordingly, we propose to
list the Upper Coosa River DPS of the frecklebelly madtom as a
threatened species with a rule issued under section 4(d) of the Act
(``4(d) rule''). If we finalize this rule as proposed, it would add
this DPS to the List of Endangered and Threatened Wildlife and extend
the Act's protections to the DPS. We also propose to designate critical
habitat for the Upper Coosa River DPS under the Act. In total,
approximately 134 river miles (216 kilometers) in Georgia and Tennessee
fall within the boundaries of the proposed critical habitat
designation. We also announce the availability of a draft economic
analysis (DEA) of the proposed designation of critical habitat for the
Upper Coosa River DPS.
DATES: We will accept comments received or postmarked on or before
January 19, 2021. Comments submitted electronically using the Federal

SUPPLEMENTARY INFORMATION:
Executive Summary
Why we need to publish a rule. Under the Act, if we determine that
a species may be an endangered or threatened species throughout all or
a significant portion of its range, we are required to promptly publish
a proposal in the Federal Register and make a determination on our
proposal within 1 year. To the maximum extent prudent and determinable,
we must designate critical habitat for any species that we determine to
be an endangered or threatened species under the Act. Listing a species
as an endangered or threatened species and designation of critical
habitat can only be completed by issuing a rule.
What this document does. This rule proposes the listing of the
Upper Coosa River distinct population segment (DPS) of frecklebelly
madtom as a threatened species with a rule under section 4(d) of the
Act and proposes the designation of critical habitat for the DPS.
The basis for our action. Under the Act, we may determine that a
species is an endangered or threatened species because of 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 factors driving the
status of the Upper Coosa River DPS are habitat destruction and
degradation caused by agriculture and developed land uses resulting in
poor water quality (Factor A).
Section 4(a)(3) of the Act requires the Secretary of the Interior
(Secretary) to designate critical habitat concurrent with listing to
the maximum extent prudent and determinable. Section 3(5)(A) of the Act
defines critical habitat as (i) the specific areas within the
geographical area occupied by the species, at the time it is listed, on
which are found those physical or biological features (I) essential to
the conservation of the species and (II) which may require special
management considerations or protections; and (ii) specific areas
outside the geographical area occupied by the species at the time it is
listed, upon a determination by the Secretary that such areas are
essential for the conservation of the species. Section 4(b)(2) of the
Act states that the Secretary must make the designation on the basis of
the best scientific data available and after taking into consideration
the economic impact, the
[[Page 74051]]
impact on national security, and any other relevant impacts of
specifying any particular area as critical habitat.
Peer review. 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 the expert
opinions of 10 appropriate specialists regarding the SSA report. We
received responses from two specialists, and their input informed this
proposed rule. The purpose of peer review is to ensure that our listing
determinations, critical habitat designations, and 4(d) rules are based
on scientifically sound data, assumptions, and analyses. The peer
reviewers have expertise in the biology, habitat, and threats to the
species.
Because we will consider all comments and information we receive
during the comment period, our final determinations may differ from
this proposal. Based on the new information we receive (and any
comments on that new information), we may conclude that the Upper Coosa
River DPS is endangered instead of threatened, or we may conclude that
the DPS does not warrant listing. Such final decisions would be a
logical outgrowth of this proposal, as long as we: (1) Base the
decisions on the best scientific and commercial data available after
considering all of the relevant factors; (2) do not rely on factors
Congress has not intended us to consider; and (3) articulate a rational
connection between the facts found and the conclusions made, including
why we changed our conclusion.
Information Requested
We intend that any final action resulting from this proposed rule
will be based on the best scientific and commercial data available and
be as accurate and as effective as possible. Therefore, we request
comments or information from other concerned governmental agencies,
Native American Tribes, the scientific community, industry, or any
other interested parties concerning this proposed rule.
We particularly seek comments concerning:
(1) The frecklebelly madtom's biology, range, distribution, and
population trends, particularly in the upper Coosa River watershed in
Georgia and Tennessee, including:
(a) Biological or ecological requirements of the frecklebelly
madtom, including habitat requirements for feeding, breeding, and
sheltering;
(b) Genetics and taxonomy;
(c) Historical and current range, including distribution patterns;
(d) Historical and current population levels, and current and
projected trends; and
(e) Past and ongoing conservation measures for the frecklebelly
madtom, its habitat, or both.
(2) Factors that may affect the continued existence of the
frecklebelly madtom, which may include habitat modification or
destruction, overutilization, disease, predation, the inadequacy of
existing regulatory mechanisms, or other natural or manmade factors.
(3) Biological, commercial trade, or other relevant data concerning
any threats (or lack thereof) to the frecklebelly madtom and existing
regulations that may be addressing those threats.
(4) Additional information concerning the historical and current
status, range, distribution, and population size of the frecklebelly
madtom, and specifically the Upper Coosa River DPS, including the
locations of any additional populations of the frecklebelly madtom.
(5) Information on regulations that are necessary and advisable to
provide for the conservation of the Upper Coosa River DPS of
frecklebelly madtom and that the Service can consider in developing a
4(d) rule for the DPS, including information concerning the extent to
which we should include any of the section 9 prohibitions in the 4(d)
rule or whether any other forms of take should be excepted from the
prohibitions in the 4(d) rule. We particularly seek comments
concerning:
(a) Whether we should add a provision to except incidental take
resulting from silvicultural practices and forest management activities
that implement State-approved best management practices and comply with
forest practice guidelines related to water quality standards.
(b) Whether there are additional provisions the Service may wish to
consider for the section 4(d) rule in order to conserve, recover, and
manage the Upper Coosa River DPS.
(6) The reasons why we should or should not designate habitat as
``critical habitat'' under section 4 of the Act (16 U.S.C. 1531 et
seq.), including information to inform the following factors that the
regulations identify as reasons why designation of critical habitat may
be not prudent:
(a) 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;
(b) The present or threatened destruction, modification, or
curtailment of a species' habitat or range is not a threat to the
species, or threats to the species' habitat stem solely from causes
that cannot be addressed through management actions resulting from
consultations under section 7(a)(2) of the Act; or
(c) No areas meet the definition of critical habitat.
(7) Specific information on:
(a) The amount and distribution of Upper Coosa River DPS habitat;
(b) Information on the physical or biological features essential to
the conservation of the DPS;
(c) What areas, that were occupied at the time of listing and that
contain the physical or biological features essential to the
conservation of the DPS, such as the Coosawattee River in Georgia,
should be included in the critical habitat designation and why;
(d) The methods we used, particularly the use of environmental DNA,
to identify occupied critical habitat for each of the units;
(e) Special management considerations or protection that may be
needed in critical habitat areas we are proposing, including managing
for the potential effects of climate change; and
(f) What areas not occupied at the time of listing are essential
for the conservation of the DPS and should be included as critical
habitat and why. We particularly seek comments:
(i) Regarding whether occupied areas are adequate for the
conservation of the DPS; and
(ii) Providing specific information regarding whether or not
unoccupied areas would, with reasonable certainty, contribute to the
conservation of the DPS and contain at least one physical or biological
feature essential to the conservation of the DPS.
(8) Land use designations and current or planned activities in the
subject areas and their possible impacts on proposed critical habitat.

(10) Information on the extent to which the description of probable
economic impacts in the draft economic analysis is a reasonable
estimate of the likely economic impacts.
(11) Whether any specific areas we are proposing for critical

Previous Federal Actions
On April 20, 2010, we were petitioned by the Center for Biological
Diversity and others to list 404 aquatic species in the southeastern
United States, including the frecklebelly madtom, under the Act. In
response to the petition, we completed a partial 90-day finding on
September 27, 2011 (76 FR 59836), in which we announced our finding
that the petition contained substantial information indicating that
listing may be warranted for numerous species, including the
frecklebelly madtom. On April 15, 2015, the Center for Biological
Diversity amended a complaint against the Service for failure to
complete a 12-month finding for the frecklebelly madtom in accordance
with statutory deadlines. On September 9, 2015, the Service and the
Center for Biological Diversity filed stipulated settlements in the
District of Columbia, agreeing that the Service would submit to the
Federal Register a 12-month finding for the frecklebelly madtom no
later than September 30, 2020 (Center for Biological Diversity v.
Jewell, case 1:15-CV-00229-EGS). This document constitutes our
concurrent 12-month warranted petition finding, proposed listing rule,
and proposed critical habitat rule.
Supporting Documents
An SSA team prepared an SSA report for the frecklebelly madtom. 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. The Service sent
the SSA report to 10 independent peer reviewers and received 2
responses. The Service also sent the SSA report for review to 13
partners, including scientists with expertise in fish biology, stream
and riverine ecology, and factors negatively and positively affecting
the species. We received review from two partners, Mississippi Museum
of Natural Science and Georgia Department of Natural Resources.
I. Proposed Listing Determination
Background
A thorough review of the taxonomy, life history, and ecology of the
frecklebelly madtom (Noturus munitus) is presented in the SSA report
(version 1.2; Service 2020, pp. 5-15; available at https://www.fws.gov/southeast/ and at https://www.regulations.gov under Docket No. FWS-R4-
ES-2020-0058).
The frecklebelly madtom is a catfish species that inhabits the main
channels and larger tributaries of large river systems in Louisiana,
Mississippi, Alabama, Georgia, and Tennessee. The species has a broad
but disjunct distribution across the Pearl River watershed and Mobile
River Basin, with populations in the Pearl River and Bogue Chitto River
in the Pearl River watershed and the Upper Tombigbee, Alabama, Cahaba,
Etowah, and Conasauga river systems in the Mobile River Basin (Piller
et al. 2004, p. 1004; Bennett et al. 2010, pp. 507-508). Throughout its
range, the frecklebelly madtom primarily occupies streams and rivers
within the Gulf Coastal Plain physiographic province; however, it also
occurs in the Ridge and Valley physiographic province in the Conasauga
River and Piedmont Upland physiographic province in the Etowah River
(Mettee et al. 1996, pp. 408-409).
The frecklebelly madtom is a small, stout catfish reaching 99
millimeters (mm) (3.9 inches (in)) in length (Etnier and Starnes 1993,
p. 324) and distinctively marked with dark saddles (Suttkus and Taylor
1965, p. 171). The color of the frecklebelly madtom is a mixture of
light yellows with brownish patches and a combination of many scattered
specks or freckles on the underside, which provides camouflage in its
preferred habitats and inspired its common name (Suttkus and Taylor
1965, p. 176; Vincent 2019, unpaginated). The fins' colors are
typically mottled or blotched (Etnier and Starnes 1993, p. 324). The
frecklebelly madtom is armed with venomous pectoral and dorsal spines
used to defend against predation and has barbels around the mouth that
act as sensory organs.
The species belongs in the family Ictaluridae, and all species in
the genus Noturus, referred to as madtoms, are diminutive and possess
long and low adipose fins (i.e., found on the back behind the dorsal
fin) (Page and Burr 2011, p. 207). The currently recognized taxon is
Noturus munitus (Suttkus and Taylor 1965, entire; Rhode 1978, p. 465).
Since the time of description, uncertainty regarding the taxonomic
status of some populations of frecklebelly madtom has arisen. In 1998,
the name ``Coosa madtom'' (Noturus sp. cf. N. munitus) was coined to
describe the madtoms, previously identified as frecklebelly madtom, in
the Conasauga and Etowah Rivers that were morphologically distinct from
the
[[Page 74053]]
frecklebelly madtom found elsewhere (Boschung and Mayden 2004, p. 347;
Neely 2018, p. 1). However, a recent analysis of the existing
morphological and genetic datasets documented substantial genetic
divergence between all populations from distinct watersheds. The Pearl
and Mobile basin populations exhibited the strongest genetic
divergence, followed by Tombigbee and Alabama River (Cahaba and Coosa)
populations (Neely 2018, entire). The Cahaba and Coosa populations
exhibited the lowest genetic differentiation and could not be reliably
diagnosed based on morphology. Therefore, because the data indicate
divergence between populations but do not support the description of
distinct subspecies or species, we consider each population of
frecklebelly madtom to be a separate evolutionary significant unit
(ESU) (Neely 2018, p. 10) for purposes of this determination. ESUs are
partially defined as a population that ``represents an important
component in the evolutionary legacy of a species'' (Waples 1991, p.
12). Because evolution is a continual process, elements that represent
a species' evolutionary legacy are also important elements of a
species' adaptive capacity. Therefore, the ESUs recommended by Neely
(2018, entire) were used to inform our analysis on the frecklebelly
madtom's representation, an attribute of the species' viability
(Service 2020, pp. 3, 35-37).
For the frecklebelly madtom to survive and reproduce, individuals
need suitable habitat that supports essential life functions at all
life stages. Three elements appear to be essential to the survival and
reproduction of individuals: Flowing water, stable substrate, and
aquatic vegetation. The frecklebelly madtom typically occurs over firm
gravel substrates, such as shoals and riffles, in small to large swift-
flowing streams often associated with large rivers and their
tributaries (Suttkus and Taylor 1965, pp. 177-178; Mettee et al. 1996,
p. 409; Vincent 2019, unpaginated). However, the species will use
streams dominated with sand substrates if suitable cover such as large
woody debris is present (Wagner 2019, pers. comm.). Cover is an
important habitat factor for the species, as it provides for
concealment against predators (Vincent 2019, unpaginated), foraging
habitat, and nesting habitat. In some rivers where the species is
found, the frecklebelly madtom is often associated with aquatic
vegetation, such as river weed (Podostemum), and under large, flat
rocks (Mettee et al. 1996, p. 409, Freeman et al. 2003, p. iii). In the
upper Etowah and Conasauga Rivers, the frecklebelly madtom has been
collected in moderate to swift currents over boulders, rubble, cobble,
and coarse gravel and around concentrations of river weed.
The frecklebelly madtom is likely nocturnal and most active at
night. The species has a lifespan of approximately 5 years (Mettee et
al. 1996, pp. 408-409) and is reproductively mature in the second
summer after birth, similar to other madtom species (Burr and Stoeckel
1999, p. 65). In the wild, reproduction is thought to occur between
June and July (Trauth et al. 1981, p. 66). At the Private John Allen
National Fish Hatchery in Tupelo, MS, frecklebelly madtoms have been
observed spawning between the end of May to mid-August (Schwarz 2020,
unpublished report). The female produces 50 to 70 eggs, which are
released all at one time (Trauth et al. 1981, p. 66). Fecundity in
madtoms is among the lowest for North American freshwater fishes due to
their small size, relatively large egg size, and high level of parental
care given to the fertilized eggs (embryos) and larvae (Dinkins and
Shute 1996, pp. 58-60; Burr and Stoeckel 1999, pp. 66-67). However, the
frecklebelly madtom is considered highly fecund for a madtom and among
the highest fecundity known for its subgenus, Rabida (Bennett et al.
2010, p. 507).
Nesting sites for madtoms are typically cavities under natural
material (rocks, logs, empty mussel shells) or human litter (inside
cans or bottles, under boards). Madtoms construct cavities on the
bottoms of streams by moving substrate using their heads to push gravel
or their mouths to carry and transport gravel and pebbles (Vincent
2019, unpaginated). Both males and females may construct nesting
cavities (Burr and Stoeckel 1999, p. 69).
The species is an opportunistic insectivore feeding on a variety of
aquatic insects and larvae, including caddisflies, mayflies,
blackflies, and midges (Miller 1984, p. 9). There appear to be seasonal
shifts in food preference between the sexes, with males typically
preferring caddisflies in the fall months, and the females preferring
midges during the same time (Miller 1984, p. 10).
Regulatory and Analytical Framework
Regulatory Framework
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 is an ``endangered species'' or a ``threatened
species.'' 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 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 expected response by the species,
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
[[Page 74054]]
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. The term
``foreseeable future'' extends only so far into the future as the
Service can reasonably determine that both the future threats and the
species' responses to those threats are likely. In other words, the
foreseeable future is the period of time in which we can make reliable
predictions. ``Reliable'' does not mean ``certain''; it means
sufficient to provide a reasonable degree of confidence in the
prediction. Thus, a prediction is reliable if it is reasonable to
depend on it when making decisions.
It is not always possible or necessary to define foreseeable future
as a particular number of years. Analysis of the foreseeable future
uses the best scientific and commercial data available and should
consider the timeframes applicable to the relevant threats and to the
species' likely responses to those threats in view of its life-history
characteristics. Data that are typically relevant to assessing the
species' biological response include species-specific factors such as
lifespan, reproductive rates or productivity, certain behaviors, and
other demographic factors.
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 a decision by
the Service on whether the species should be proposed for listing as an
endangered or threatened species under the Act. It does, however,
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. The following is a summary
of the key results and conclusions from the SSA report; the full SSA
report can be found at https://www.fws.gov/southeast/ and at https://www.regulations.gov under Docket No. FWS-R4-ES-2020-0058.
To assess frecklebelly madtom viability, we used the three
conservation biology principles of resiliency, redundancy, and
representation (Shaffer and Stein 2000, pp. 306-310). Briefly,
resiliency supports the ability of the species to withstand
environmental and demographic stochasticity (for example, wet or dry,
warm or cold years), redundancy supports the ability of the species to
withstand catastrophic events (for example, droughts, large pollution
events), and representation supports the ability of the species to
adapt over time to long-term changes in the environment (for example,
climate changes). In general, the more resilient and redundant a
species is and the more representation it has, the more likely it is to
sustain populations over time, even under changing environmental
conditions. 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.
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. For frecklebelly madtom
populations to be resilient, the needs of individuals (flowing water,
substrate, and aquatic vegetation) must be met at a large scale. Stream
reaches with suitable habitat must be large enough to support an
appropriate number of individuals to avoid issues associated with small
population sizes, such as inbreeding depression. At the species level,
the frecklebelly madtom needs a sufficient number and distribution of
healthy populations to withstand environmental stochasticity
(resiliency) and catastrophes (redundancy) and to adapt to biological
and physical changes in its environment (representation). To evaluate
the current and future viability of the frecklebelly madtom, we
assessed a range of conditions to allow us to consider the current and
future effects on resiliency, representation, and redundancy.
Delineating Representation and Resilience Units
We delineated representation and resilience units for the
frecklebelly madtom. Representation units were delineated to describe
the breadth of known genetic, phenotypic, and ecological diversity
within the species. There is evidence of differentiation in habitat
use, morphology, and genetics for areas that the frecklebelly madtom
occupies, which are disconnected spatially across the landscape.
Resilience units were delineated to describe at a local scale how the
species withstands stochastic events. These resilience units are not
meant to represent individual populations as they may represent
multiple or portions of groups of demographically linked interbreeding
individuals.
In total, we identified six representation units for the
frecklebelly madtom: Pearl River (A), upper Tombigbee River (B), lower
Tombigbee/Alabama Rivers (C), Alabama River (D), Cahaba River (E), and
upper Coosa River (F) (see table 1, below). Four representation units
(Pearl River (A), upper Tombigbee River (B), Cahaba River (E), and
upper Coosa River (F)) are the ESUs based on the evaluation of
morphometric and genetic datasets (Neely 2018, entire). Morphometric
and genetic data from the remaining two representation units (lower
Tombigbee/Alabama Rivers (C) and Alabama River (D)) were not available
to be analyzed in the 2018 study (Neely 2018, entire) and, therefore,
were not identified as ESUs in that study.
The lower Tombigbee/Alabama Rivers (C) and Alabama River (D)
representation units reflect occurrences of the species in the Mobile
River Basin that are the farthest downstream and within a large river
habitat type that is distinct from the remainder of the units in the
Mobile River Basin. Furthermore, these reaches are disconnected from
the nearest adjacent representation units by dams that act as dispersal
barriers for the species. Therefore, these reaches are assessed as two
individual representation units. The Alabama River (D) representation
unit consists of a single HUC 10 watershed that is isolated
[[Page 74055]]
from other representation units by dams. The remaining unit, lower
Tombigbee/Alabama Rivers (C), is disconnected from the upper Tombigbee
River and Alabama River units by dams.
Resilience units were delineated as aggregations of adjacent U.S.
Geological Survey Hydrological Unit Code (HUC) 10 watershed boundaries
that contain a frecklebelly madtom observation and are not disconnected
by dams or other major habitat alterations that may present a barrier
to movement. While resiliency is typically assessed at the scale of a
population, there was little information to delineate populations of
the frecklebelly madtom. By using HUC 10 watersheds, we are able to
delineate resilience units that can be measured and evaluated at a
local scale similar to that we would expect for a population. We
determined this to be the most appropriate scale for measuring
resiliency. We identified 16 resilience units consisting of 66 HUC10
watersheds across the range of the frecklebelly madtom (see table 1,
below).

Methods To Assess Current Condition
We assessed the current resiliency (ability of populations to
withstand stochastic events) of frecklebelly madtom resilience units by
considering occurrence data throughout the species' range. We used
occurrence data to estimate range extent and range geometry (i.e.,
number of named streams with occurrences). These metrics can be useful
for evaluating resiliency, as larger areas of occupied habitat and
multiple occupied streams (more complex ranges) are more robust to
stochastic events (i.e., a single more localized event would be
unlikely to negatively affect the entire population or unit if many and
larger reaches of streams were occupied). Occurrence data for the
frecklebelly madtom are only available for five of the six
representation units: The Pearl River (A), upper Tombigbee River (B),
Alabama River (D), Cahaba River (E), and upper Coosa River (F).
Therefore, we conducted our assessment of occurrences only on
resilience units within those representation units, and we categorized
current resiliency into high, moderate, low, or likely extirpated
conditions, based on our evaluation of total number of occurrences, the
number of occupied stream reaches, the length of discrete stream
reaches, and the maximum occupied stream reach estimate and available
literature (Service 2020, pp. 34-53). The Lower Tombigbee/Alabama
Rivers (C) representation unit was categorized to have unknown
resiliency (see discussion below regarding environmental DNA).
Environmental DNA (eDNA, which is DNA that is shed into the
environment by an organism during its life) belonging to the
frecklebelly madtom was collected in the Conasauga River (F1),
Coosawattee River (F2), Etowah River (F3), and portions of the lower
Alabama River (C2) and lower Tombigbee River (C1) (Freeman and Bumpers
2018, entire; Janosik and Whittaker 2018, entire). Within the
Coosawattee River (F2), the lower Alabama River (C2), and the lower
Tombigbee River (C1), eDNA is the only evidence of the species'
presence within the period of record (1950-2019). Collecting and
analyzing water samples for eDNA provides a means of rapidly surveying
aquatic habitats to help identify potentially occupied sites for a
species. However, uncertainty of these data revolves around the origin
and fate of the individuals that shed the DNA and the length of time
the eDNA persists in the environment. For the purposes of this
analysis, we used eDNA data as evidence to support our conclusion that
the probability of the species being present in a particular unit is
greater than zero. As described above, we used occurrence data to
assess resiliency. If units are known only from eDNA data, an unknown
resiliency was determined since we have no occurrence information.
We assessed representation for the frecklebelly madtom as the
number of resilient populations within a representation unit. Finally,
we assessed frecklebelly madtom redundancy (ability of species to
withstand catastrophic events) by evaluating the number and
distribution of resilient populations throughout the species' range.
Current Condition of Frecklebelly Madtom
The historical range for the frecklebelly madtom includes two large
river basins that enter into the Gulf of Mexico: The Pearl River Basin
and the Mobile River Basin. The Pearl River Basin is in eastern
Louisiana and southern Mississippi (identified as Pearl River (A)
representation unit in the SSA). The Mobile River Basin consists of the
Tombigbee River in eastern Mississippi and western Alabama (Upper
Tombigbee (B) representation unit); the upper Alabama (Alabama
[[Page 74056]]
River (D) representation unit) and Cahaba Rivers (Cahaba River (E)
representation unit) in central Alabama; the Etowah River (part of the
Upper Coosa River (F) representation unit) in northern Georgia; and the
Conasauga River (part of the Upper Coosa River (F) representation unit)
in northern Georgia and southeastern Tennessee. Historically, the
species was likely more widespread in the Mobile Bay drainage but was
extirpated from large river habitats after the creation of numerous
impoundments, and thus, the species' current representation has been
reduced from historical levels. Currently, the species is known to be
extant in four (Pearl River (A), Upper Tombigbee River (B), Cahaba
River (E), and Upper Coosa River (F)) of the six representation units.
Within the Pearl River (A) representation unit, there are two
resilience units (Bogue Chitto River (A1) and Pearl River (A2))
assessed to have high resiliency to stochastic events based on stable
populations and complex range geometry with 15 occupied streams in the
Pearl River. In addition, recent surveys (2009-2019) observed
frecklebelly madtom at 83 percent of known historical sites (i.e., any
site in which the species was previously observed) (Wagner et al. 2018,
entire; Service 2020, p. 59).
Within the Upper Tombigbee River (B) representation unit, there is
one resilience unit (Buttahatchee River (B4)) assessed to have high
resiliency, three (East Fork Tombigbee River (B1), Sipsey River (B2),
and Luxapallila Creek (B3)) have moderate resiliency, and two are
likely extirpated (Upper Tombigbee River (B6) and Bull Mountain Creek
(B5)). The Buttahatchee River (B4) unit has been identified as a
stronghold of the species where it has consistently been collected in
higher numbers (Shepard et al. 1997, p. 23, Bennett et al. 2008, p.
470). For the East Fork of the Tombigbee River (B1) unit, the species
has recent (2009-2019) collections of more than 100 individuals per
survey event (i.e., occurrence) of frecklebelly madtom. However, there
has been a loss of habitat, altered water quality, and loss of
connectivity in the East Fork with numerous structures installed for
the Tennessee-Tombigbee Waterway (Tenn-Tom Waterway) (Millican et al.
2006, p. 3-4). Within the Sipsey River (B2) unit, experts have
indicated that the habitat is excellent with few threats and the
populations appear stable, albeit few records for them exist (Shepard
et al. 1997, pp. 9, 23). Frecklebelly madtom persists in Luxapallila
Creek (B3) with stable populations and recent (2009-2019) collections
of almost 100 individuals per survey event (i.e., occurrence).
Historically, the mainstem of the upper Tombigbee River (mainstem,
B6) unit was considered to support robust populations of the
frecklebelly madtom with some sites producing single collections of
over 300 individuals during the assessment period from 1950-1987
(Bennet et al. 2008, p. 466; Service 2020, p. 49). However, the
construction of the Tenn-Tom Waterway, a canal system that connects the
Tombigbee River to the Tennessee River for commercial navigation,
eliminated the suitable gravel-cobble habitat for the species (Shepard
et al. 1997, p. 4). Despite fish assemblage surveys undertaken since
the construction of the waterway (e.g., Millican et al. 2006, entire),
observations of the species cease in the mainstem of the upper
Tombigbee River (B6) after 1980 (Bennett et al. 2008, p. 466), thus
supporting the species' likely extirpation from this formerly occupied
habitat. The frecklebelly madtom has not been observed in the Bull
Mountain Creek (B5) unit since 1978-1987 assessment period; this unit
was also drastically altered by the construction of the Tenn-Tom
Waterway and is currently bisected by the canal system (Millican et al.
2006, p. 3). The habitat lost from this major construction and
engineering activity has likely caused the extirpation of the
frecklebelly madtom in the upper Tombigbee River (B6) (Millican et al.
2006 p. 84; Shepard 2004, p. 221; Bennett et al. 2008, p. 467) and Bull
Mountain Creek (B5) (Shepard 2004, p. 221) resilience units.
Within the Lower Tombigbee/Alabama Rivers (C) representation unit,
there are two resilience units (Lower Tombigbee River (C1) and Lower
Alabama River (C2)) assessed to have unknown resiliency. There are no
traditional occurrence data of this species for either resilience unit;
however, eDNA of frecklebelly madtom was found in both units (Janosik
and Whittaker 2018, p. 7).
Within the Alabama River (D) representation unit, there is one
resilience unit (Alabama River (D1)) assessed to be likely extirpated.
Following the construction of the Miller's Ferry Lock and Dam and
Claiborne Dam in the late 1960s, there have been no occurrences of this
species in the Alabama River (D1) unit, despite efforts to locate the
species (Shepherd et al. 1997, p. 18).
Within the Cahaba River (E) representation unit, one resilience
unit (Cahaba River (E1)) was estimated to have moderate resiliency to
stochastic events. The Cahaba River system is believed to be a
stronghold for the species (Neely 2018, p. 11) where it appears to be
abundant (Bennet et al. 2008, p. 467). The Alabama River-Big Swamp
Creek (E2) resilience unit is likely extirpated; no observations have
been made of this species in the unit since the late 1960s after the
construction of Miller's Ferry Lock and Dam and Claiborne Dam despite
efforts to locate the species (Shepherd et al. 1997, p. 18; Bennet et
al. 2008, p. 464).
Within the Coosa River (F) representation unit, one resilience unit
(Conasauga River (F1)) was estimated to have low resiliency, one with
moderate resiliency (Etowah River (F3)), and one with unknown
resiliency (Coosawattee River (F2)). In the Conasauga River (F1), fish
assemblage and abundance from the 1990s-2000s documented declines in
several fish species, including the frecklebelly madtom, and after
2000, the frecklebelly madtom was no longer detected in fish surveys
(Freeman et al. 2003, pp. 569-570; Bennett et al. 2008 p. 466). These
surveys indicate a reduced resiliency in the Conasauga River (F1),
because the best available occurrence data present a transition from a
measurable population of the frecklebelly madtom to an unmeasurable
one. Despite a 20-year lapse since the last observation of the
frecklebelly madtom, the current presence of the species in the
Conasauga River (F1) is supported by eDNA that was collected in 2017
and 2018 (Freeman and Bumper 2018, entire), as described above.
Furthermore, the Conasauga River (F1) has not experienced the same type
of habitat modifications as other rivers that have caused localized
extirpation of the species (dams, impoundments, and channelization),
and the species has been observed more recently in river surveys than
in river sections where it is considered extirpated. Therefore, we
determined that the species remains present in the Conasauga River but
with low resiliency to stochastic events, as estimated from the
occurrence data. Within the Etowah River (F3), frecklebelly madtom
populations appear stable, albeit at lower levels of abundance, as the
patterns of occurrence in the most recent time period is similar to
time periods prior to 1998. There are no historical occurrence data or
direct observations of the species from the Coosawattee River (F2)
resilience unit. Environmental DNA for the frecklebelly madtom was
found in portions of this unit (Freeman and Bumpers 2018, p. 9);
therefore, we assessed this unit as having an unknown resiliency.
[[Page 74057]]
Overall, the frecklebelly madtom was assessed to have three units
with high resiliency, five units with moderate resiliency, one unit
with low resiliency, three units with unknown resiliency (eDNA only),
and four units that are likely extirpated.
For species' redundancy, we assessed the number and distribution of
resilient populations across the frecklebelly madtom's range, and we
considered catastrophic events that could impact frecklebelly madtom.
Catastrophic events may include chemical spills, large and rapid
changes in upstream land use that alter stream characteristics and
water quality downstream, new impoundments or other engineered devices
that alter natural hydrological processes, and potential effects of
climate change, such as drought and increases in occurrence of flash
flooding events. Given the broad distribution of extant resilience
units and several units assessed as having moderate to high resiliency,
it is unlikely that a catastrophic event would impact the entire
species' range. Therefore, the frecklebelly madtom exhibits a moderate
to high degree of redundancy and that level of redundancy has remained
relatively stable over time.
Risk Factors for Frecklebelly Madtom
We reviewed the potential risk factors (see discussion of section
4(a)(1) of the Act, above) that are affecting the frecklebelly madtom
now and are expected to affect it into the future. We have determined
that habitat destruction and degradation caused by agriculture and
development resulting in poor water quality (Factor A) pose the largest
risk to the current and future viability of the frecklebelly madtom.
Other potential stressors to the species are habitat degradation
resulting from channelization, dams, and impoundments (Factor A) and
climate change (Factor E). We find the species does not face
significant threats from overutilization (Factor B), disease or
predation (Factor C), or invasive species (Factor E). We also reviewed
the conservation efforts being undertaken for the habitat in which the
frecklebelly madtom occurs. A brief summary of relevant stressors is
presented below; for a full description, refer to chapter 4 of the SSA
report (Service 2020, entire).
Water Quality
The frecklebelly madtom, like other benthic aquatic species, is
sensitive to poor water quality (Warren et al. 1997, p. 125) and needs
clean, flowing water to survive; thus water quality degradation is
considered a threat to the species. Changes in water chemistry and flow
patterns, resulting in a decrease in water quality and quantity have
detrimental effects on madtoms, because they can render aquatic habitat
unsuitable for occupancy.
Inputs of point (discharge from particular pipes) and nonpoint
(diffuse land surface runoff) source pollution across the frecklebelly
madtom range are numerous and widespread. Point source pollution can be
generated from inadequately treated effluent from industrial plants,
sanitary landfills, sewage treatment plants, active surface mining,
drain fields from individual private homes, and others (Service 2000,
pp. 14-15). Nonpoint pollution originates from agricultural activities,
poultry and cattle feedlots, abandoned mine runoff, construction,
failing septic tanks, and contaminated runoff from urban areas (Deutsch
et al. 1990, entire; Service 2000, pp. 14-15). These sources contribute
pollution to streams via sediments, heavy metals, fertilizers,
herbicides, pesticides, animal wastes, septic tank and gray water
leakage, and oils and greases. Water quality and native aquatic fauna
decline as a result of this pollution through nitrification, decreases
in dissolved oxygen concentration, increases in acidity and
conductivity, or direct introduction of toxicants. These alterations
likely have direct (e.g., decreased survival and/or reproduction) and
indirect (e.g., loss, degradation, and fragmentation of habitat)
effects. For some aquatic species, including the frecklebelly madtom,
submergent vegetation provides critical spawning habitat for adults,
refugia from predators, and habitat for prey of all life stages (Jude
and Pappas 1992, pp. 666-667, Freeman et al. 2003, p. 54). Degraded
water quality and the high algal biomass that result from pollutant
inputs cause loss of these critical submergent plant species (Chow-
Fraser et al.1998, pp. 38-39) that are vital habitat for the
frecklebelly madtom.
The frecklebelly madtom is intolerant to sedimentation (Shepard
2004, p. 221; MMNS 2014, p. 35), and sedimentation is a concern
throughout the species' range. Researchers have documented a negative
relationship between occurrence of the frecklebelly madtom and human-
induced increases of sediment within the upper Tombigbee River
(mainstem), Alabama River, Cahaba River, Luxapallila Creek, Etowah
River, and Conasauga River (Burkhead et al. 1997, pp. 406-413; Shepherd
et al. 1997, pp. 15-19; Freeman et al. 2002, pp. 18-19; Freemen et al.
2017, pp. 429-430). Human-induced increases in sediment are likely a
factor in local declines of the species. In addition, the frecklebelly
madtom's habitat requirements make it vulnerable to activities that
disturb substrate integrity. The species is restricted to habitat with
pea-sized gravel, cobble, or slab-rock substrates not embedded in large
amounts of silt (Bennett et al. 2008, p. 467; Bennett and Kuhajda.
2010, p. 510), although it has also been found to occupy some stable
streams with a sandy yet stable substrate. Degradation from
sedimentation, physical habitat disturbance, and contaminants threaten
the habitat and water quality on which the frecklebelly madtom depends.
Sedimentation from an array of land uses (e.g., urbanization,
agriculture, channel maintenance activities) could negatively affect
the species by reducing growth rates, disease tolerance, and gill
function; reducing spawning habitat, reproductive success, and egg
(embryo), larva, and juvenile development; reducing food availability
through reductions in prey; reducing foraging efficiency; and reducing
shelter.
A wide range of current activities and land uses, including
agricultural practices, construction, stormwater runoff, unpaved roads,
poor forest management, utility crossings, and mining, can lead to
excessive sedimentation within streams. Fine sediments not only smother
streams during current ongoing activities, historical land use
practices may have substantially altered hydrological and geological
processes such that sediments continue to be input into streams for
several decades after those activities cease (Harding et al. 1998, p.
14846).
Water quality for frecklebelly madtom is particularly impacted by
three processes: Channel modification (i.e., dredging and
channelization), agriculture, and development, which are further
discussed below.
Channel Modification
Dredging and channelization have led to loss of aquatic habitat in
the Southeast (Neves et al. 1997, p. 71). Dredging and channelization
projects are extensive throughout the region for flood control,
navigation, sand and gravel mining, and conversion of wetlands into
croplands (Neves et al. 1997, p. 71; Herrig and Shute 2002, pp. 542-
543). Dredging and channelization modify and destroy habitat for
aquatic species by destabilizing the substrate, increasing erosion and
siltation, removing woody debris, decreasing habitat heterogeneity, and
stirring up contaminants that settle onto the substrate (Williams et
al. 1993, pp. 7-8; Buckner et al. 2002, entire; Bennett et
[[Page 74058]]
al. 2008, pp. 467-468). Channelization can also lead to head cutting
(an erosional process in a stream channel with a vertical cut or drop
that migrates upstream over time), which causes further erosion and
sedimentation (Hartfield 1993, pp. 131-141). Dredging can involve
snagging (the removal of woody debris from the channel), which not only
contributes to destabilization of the channel but also removes the
woody debris that provides important cover and nest locations for many
fish species, including the frecklebelly madtom (Bennett et al. 2008,
pp. 467-468).
The frecklebelly madtom was eliminated from much of the mainstem of
the Tombigbee River after the construction of the Tenn-Tom Waterway.
Tributaries to the upper Tombigbee River have also been affected by
channel modification of the Tenn-Tom Waterway due to head cutting and
other geomorphic and flow modifications (Raborn and Schramm 2003, pp.
289-301; Roberts et al. 2007, pp. 250-256; Tipton et al. 2004, pp. 49-
61), and fewer tributaries currently maintain the habitat needed by the
frecklebelly madtom in this system (Millican et al. 2006, p. 84;
Shepard 2004, pp. 220-222; Shepard et al. 1997, pp. 3-4). Similarly,
channel geomorphology and substrate are likely being affected by head
cutting due to impoundment of the Alabama River (Bennett et al. 2008,
p. 468).
Alternatively, frecklebelly madtom abundances have remained stable
in the Cahaba River throughout the modification periods that affected
surrounding drainages. The Cahaba River, Conasauga River, and some
tributaries to the upper Tombigbee River are the only remaining waters
within the range of the frecklebelly madtom that have escaped large-
scale human modification through damming or channelization (Bennet et
al. 2008, p. 468).
Agriculture
Agricultural practices such as traditional farming, feedlot
operations, and associated land use practices can contribute pollutants
to rivers. These practices can also degrade habitat by eroding stream
banks, which results in alterations to stream hydrology and
geomorphology. Nutrients, bacteria, pesticides, and other organic
compounds are generally found in higher concentrations in agricultural
areas rather than forested areas. Contaminants associated with
agriculture (e.g., fertilizers, pesticides, herbicides, and animal
waste) can degrade water quality and negatively impact instream
habitats by causing oxygen deficiencies, excess nutrification, and
excessive algal growths, which can have a direct impact on fish
community composition (Petersen et al. 1999, p. 6).
Areas within the current range of the frecklebelly madtom, which
are predominantly agricultural, are impacted by nonpoint source
sediment and agrochemical discharges altering the physical and chemical
characteristics of its habitat, thus potentially impeding its ability
to feed, seek shelter from predators, and successfully reproduce. A
negative relationship between the species and nonpoint source stressors
attributed to agriculture has been described particularly within the
Conasauga River (Freeman et al. 2017, pp. 429-430). Over the past two
decades, an increase in the use of agricultural chemicals and
practices, such as use of glyphosate-based herbicides for weed control
and land dispersion of animal waste for soil amendment, has
corresponded with marked declines in populations of fish and mussel
species in the Upper Conasauga River watershed in Georgia and Tennessee
(Freeman et al. 2017, p. 429). Nutrient enrichment of streams was found
to be widespread with high levels of nitrate and phosphorus (reported
at over 5 milligrams per liter and over 300 micrograms per liter,
respectively, within the Conasauga River) likely associated with
eutrophication, and hormone concentrations in sediments were often
above those shown to cause endocrine disruption in fish, which was
possibly related to the widespread application of poultry litter and
manure (Lasier et al. 2016, entire). Estrogens, a hormone and type of
endocrine disruptor that can be found in poultry litter, also have been
identified as a threat to aquatic fauna in the Conasauga River system
(Jacobs 2015, entire). Increased levels of estrogens can lead to
decreases in spawning success and potentially population collapse
within short timeframes (Kidd et al. 2007, p. 8899). Aquatic species
declines observed in the Conasauga watershed may be at least partially
due to hormones, as well as excess nutrients, herbicides, and
surfactants (Freeman et al. 2017, p. 429).
The amount (acreage) of agricultural land is declining across the
eastern United States with a net loss of 6.5 percent between 1973 and
2000 (Sayler et al. 2016, p. 12). As discussed below under Future
Scenarios, within the watersheds in which frecklebelly madtom occurs,
the declining trend of agricultural land is consistent with broader
trends in the eastern United States showing agricultural land declines
with time (Sayler et al. 2016, p. 12). These agricultural lands are
mostly being converted to developed and forested lands (Sayler et al.
2016, p. 12). Despite the declining trend, agricultural practices
leading to poor water quality conditions currently influence and will
continue to influence the viability of frecklebelly madtom across its
range.
Development
Development is a significant source of water quality degradation
that can reduce the survival of aquatic organisms, including the
frecklebelly madtom. Urban development can stress aquatic systems in a
variety of ways, including increasing the frequency and magnitude of
high flows in streams; increasing sedimentation and nutrient loads;
increasing contaminants and toxicity; decreasing the diversity of fish,
aquatic insects, plants, and amphibians; and changing stream morphology
and water chemistry (Coles et al. 2012, entire; CWP 2003; entire).
Sources and risks of an acute or catastrophic contamination event, such
as a leak from an underground storage tank or a hazardous materials
spill on a highway, increase as urbanization increases.
Urbanization has also been shown to impair stream quality by
impacting riparian health (Diamond et al. 2002, p. 1150). Riparian
impairment resulting from urbanization or agricultural land use can
amplify negative effects of nonpoint source pollution within the
watershed as well as impact stream quality independent of land use
within the watershed. Impacts from impervious cover can be mitigated
through riparian forest cover and good riparian health (Roy et al.
2005, p. 2318; Walsh et al. 2007, entire); however, the benefit of the
riparian cover diminishes when impervious cover (i.e., urban cover)
exceeds approximately 10 percent within the watershed (Booth and
Jackson 1997, p. 1084; Goetz et al. 2003, p. 205).
Currently, larger population centers, such as the cities of
Atlanta, Georgia, Jackson, Mississippi, and Birmingham, Alabama,
contribute substantial runoff to the watersheds occupied by the
frecklebelly madtom. In the future, urbanization is predicted to
increase in several areas across the range of the frecklebelly madtom
(see below under Future Scenarios). All watersheds, but especially the
Etowah River watershed, upstream of Lake Allatoona in Georgia are
expected to experience additional urbanization (Albanese et al. 2018,
p. 39). Conservation concerns in the Etowah River watershed have
focused on potential effects of this predicted urban growth on
imperiled fishes
[[Page 74059]]
(Burkhead et al. 1997, pp. 959-968; Wenger et al. 2010, pp. 11-21), and
previous analyses show negative correlations between occurrence of
native fishes and increases in impervious cover associated with urban
development (Wenger et al. 2008, p. 1260). In the Etowah Basin in
Georgia, models indicated that urbanization lowered fish species
richness and density and led to predictable changes in species
composition. Darters, sculpin, minnows, and endemic species declined
along the urban gradient, whereas sunfishes persisted and became the
dominant group (Walters et al. 2005, pp. 10-11). In the future, we
anticipate increased development to amplify as a population-level
factor influencing the viability of frecklebelly madtom.
Impoundments
Impoundment of rivers is a stressor to aquatic species in the
southeast (Benz and Collins 1997, pp. 22-23, 63, 91, 205, 273, 291,
397, 399, 401-406, 446; Buckner et al. 2002, pp. 10-11). Dams modify
habitat conditions and aquatic communities both upstream and downstream
of an impoundment (Winston et al. 1991, pp. 103-104; Mulholland and
Lenat 1992, pp. 193-231; Soballe et al. 1992, pp. 421-474). Upstream of
dams, habitat is flooded and in-channel conditions change from flowing
to still water, with increased depth, decreased levels of dissolved
oxygen, and increased sedimentation. Sedimentation alters substrate
conditions by filling in interstitial spaces between rocks, which
provide habitat for many species (Neves et al. 1997, pp. 63-64),
including the frecklebelly madtom. Downstream of dams, flow regime
fluctuates with resulting fluctuations in water temperature and
dissolved oxygen levels, the substrate is scoured, and downstream
tributaries are eroded (Neves et al. 1997, pp. 63-64; Schuster 1997, p.
273; Buckner et al. 2002, p. 11). Negative ``tailwater'' effects on
habitat can extend many kilometers downstream (Neves et al. 1997, p.
63). Dams fragment habitat for aquatic species by blocking corridors
for migration and dispersal, resulting in population isolation and
heightened susceptibility to extinction (Neves et al. 1997, p. 63).
Dams also preclude the ability of aquatic organisms to escape from
polluted waters and accidental spills (Buckner et al. 2002, p. 10).
Damming of streams and springs is also extensive throughout the
Southeast and occurs within the large river habitats of the
frecklebelly madtom (Etnier 1997, pp. 88-89; Morse et al. 1997, pp. 22-
23; Shute et al. 1997, pp. 458-459, Bennett et al. 2008, p. 467). Many
streams have both small ponds in their headwaters and large reservoirs
in their lower reaches (Morse et al. 1997, p. 23). Small streams on
private lands are regularly dammed to create ponds for cattle,
irrigation, recreation, and fishing, with significant ecological
effects due to the sheer abundance of these structures (Morse et al.
1997, pp. 22-23). In addition, small headwater streams are increasingly
being dammed in the Southeast to supply water for municipalities
(Buckner et al. 2002, p. 11).
Dams are known to have caused the extirpation and extinction of
many southeastern species, and existing and proposed dams pose an
ongoing threat to many aquatic species (Folkerts 1997, p. 11; Neves et
al. 1997, p. 63; Riciarddi and Rasmussen 1999, p. 1222; Service 2000,
p. 15; Buckner et al. 2002, p. 11, Olden 2016, pp. 112-122), including
the frecklebelly madtom. The construction of 10 lock and dam structures
on the Tenn-Tom Waterway, which artificially connects the Tennessee
River to the Gulf of Mexico, led to the extirpation of many species,
including the frecklebelly madtom, from the main river channel (Bennett
et al. 2008, p. 467). The frecklebelly madtom is considered extirpated
from the Alabama River, likely due to the construction of three dams in
the late 1960s and early 1970s (Bennett et al. 2008, p. 467). In
addition, the construction of one dam on the Etowah River may have
affected the frecklebelly madtom, since the species is dependent on
large-river gravel shoal substrate (Bennett et al. 2008, p. 470). As
discussed above in Current Condition of Frecklebelly Madtom, four
resilience units are likely extirpated as a result of dam construction
and large scale river modifications.
Climate Change
In the southeastern United States, several climate change models
have projected more frequent drought, more extreme heat (resulting in
increases in air and water temperatures), increased heavy precipitation
events (e.g., flooding), more intense storms (e.g., frequency of major
hurricanes increases), and rising sea level and accompanying storm
surge (IPCC 2013, entire). When taking into account future climate
projections for temperature and precipitation where the frecklebelly
madtom occurs, warming is expected to be greatest in the summer, which
is predicted to increase drought frequency. Nevertheless, annual mean
precipitation is expected to increase slightly, leading to a slight
increase in flooding events (Alder and Hostetler 2013, unpaginated;
IPCC 2013, entire; USGS 2020, unpaginated). Changes in climate may
affect ecosystem processes and communities by altering the abiotic
conditions experienced by biotic assemblages, resulting in potential
effects on community composition and individual species interactions
(DeWan et al. 2010, p. 7).
The frequency, duration, and intensity of droughts are likely to
increase in the southeastern United States as a result of global
climate change (Konrad et al. 2013, p. 34), which could negatively
affect stream flows in the region. Stream flow is strongly correlated
with important physical and chemical parameters that limit the
distribution and abundance of riverine species (Power et al. 1995,
entire; Resh et al. 1988, pp. 438-439) and regulates the ecological
integrity of flowing water systems (Poff et al. 1997, p. 770).
To understand how climate change is projected to affect where
frecklebelly madtom occurs, we used the National Climate Change Viewer
(NCCV), a climate-visualization tool developed by the U.S. Geological
Survey (USGS), to generate future climate projections across the range
of the species. The NCCV is a web-based tool for visualizing and
assessing projected changes in climate and water balance at watershed,
State, and county scales (USGS 2020, unpaginated). To evaluate the
effects of climate change in the future, we used projections from
Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 to
characterize projected future changes in climate and water resources,
averaged for the South-Atlantic Gulf Region encompassing the range of
the frecklebelly madtom (Service 2020, pp. 27-31). The projections
estimate changes in mean annual values for maximum air temperature,
minimum air temperature, monthly precipitation, and monthly runoff,
among other factors, from historical (1981-2010) to future (2050-2074)
time series.
Within the range of the frecklebelly madtom, the NCCV projects
that, under the RCP 4.5 scenario, maximum air temperature will increase
by 1.9 degrees Celsius ([deg]C) (3.4 degrees Fahrenheit ([deg]F)),
minimum air temperature will increase by 1.8 [deg]C (3.2 [deg]F),
precipitation will increase by 5.36 millimeters (0.2 inches) per month,
and runoff will remain the same in the 2050-2074 time period (USGS
2020, unpaginated). Under the more extreme RCP 8.5 scenario, the NCCV
projects that maximum air temperature will increase by 2.8 degrees
Celsius ([deg]C) (5 degrees Fahrenheit ([deg]F)), minimum air
[[Page 74060]]
temperature will increase by 2.7 [deg]C (4.9 [deg]F), precipitation
will increase by 5.36 millimeter (0.2 inches) per month, and runoff
will remain the same in the 2050-2074 time period (USGS 2020,
unpaginated). These estimates indicate that, despite projected minimal
increases in annual precipitation, anticipated increases in maximum and
minimum air temperatures will likely offset those gains. Based on these
projections, the frecklebelly madtom will on average be exposed to
increased air temperatures across its range, despite limited increases
in precipitation; however, these projections are not a one-to-one air
to stream water temperature comparison.
Despite the recognition of climate effects on ecosystem processes,
there is uncertainty within each model and model ensembles about what
the exact climate future will be, and there is uncertainty in how the
ecosystems and species will respond. Although there are several
potential risks associated with long-term climate change as described
above, there is uncertainty regarding how the frecklebelly madtom will
respond to these risks. The species occupies some tributaries
throughout its range, but the frecklebelly madtom has a preference for
habitat in larger rivers and this may provide a buffer to changes
induced by climate change, particularly from issues associated with
drought. Therefore, we do not consider climate change to be a primary
risk factor for the species at this time.
Conservation Efforts
The frecklebelly madtom is recognized as a species of concern in
all States where it occurs and is protected by State statute in four
States where it occurs. This species is listed as endangered by the
State of Georgia (GADNR 2015, p. 74), endangered by the State of
Mississippi (Mississippi Museum of Natural Science 2015, p. 36), and
threatened by the State of Tennessee (TWRA 2015, Appendix C). In
Alabama, the frecklebelly madtom is designated as a protected nongame
species under Alabama Code 220-2-.92. In general, the protections
accorded to the frecklebelly madtom by Mississippi, Alabama, Georgia,
and Tennessee prohibit direct exploitation of the species without a
permit within those States.
Beginning in 2017, the Private John Allen National Fish Hatchery
partnered with the Mississippi Department of Wildlife Fisheries and
Parks to collect individuals of the frecklebelly madtom within that
State to study marking techniques, establish captive husbandry methods,
and conduct life-history studies. This effort has led to successful
propagation of the species, documented important components of the
species' life history, and collected data that can be used to develop
long-term, captive-propagation efforts, although no individuals have
been released.
Throughout the range of the species, portions of occupied rivers
and surrounding lands are owned and managed by State and Federal
entities that prioritize conservation as a management objective.
Generally, these entities help to maintain the natural ecosystem
functioning of a river by managing terrestrial areas in a more natural
state and limiting disturbance adjacent to rivers. However, properties
managed by the Service, U.S. Forest Service, and the Dawson Forest
Wildlife Management Area (WMA) managed by the Georgia Department of
Natural Resources, are known to specifically consider and manage for
the conservation of aquatic species and their habitats. It is expected
that the frecklebelly madtom will be positively affected by management
on these lands. These conservation lands and the adjacent rivers
occupied by the frecklebelly madtom include: Portions of the Bogue
Chitto and Pearl Rivers within the Bogue Chitto National Wildlife
Refuge (NWR, Service) in Louisiana; portions of the Bogue Chitto River
within Bogue Chitto State Park (Louisiana Department of Culture,
Recreation, and Tourism) in Louisiana; portions of the Pearl River
within the Pearl River WMA (Louisiana Department of Wildlife and
Fisheries) in Louisiana; portions of the Cahaba River within the Cahaba
NWR (Service) in Alabama; portions of the Conasauga River within the
Cherokee National Forest (U.S. Department of Agriculture (USDA) U.S.
Forest Service) in Georgia; and portions of the Etowah River within the
Dawson Forest WMA (Georgia Department of Natural Resources) in Georgia.
In addition, the Etowah River catchment area upstream of habitat
occupied by the frecklebelly madtom and managed by the Chattahoochee-
Oconee National Forest (USDA U.S. Forest Service) is expected to
benefit the species by providing good water quality to lower river
reaches.
The Natural Resources Conservation Service (NRCS), USDA, designated
the Conasauga River as a Working Lands for Wildlife (WLFW) landscape in
2017 (USDA 2020, unpaginated) and will provide additional funds and
human-power to improve water quality and aquatic habitat in the
watershed. The project will provide technical and financial assistance
to help landowners improve water quality and help producers plan and
implement a variety of conservation activities or practices that
benefit aquatic species. The frecklebelly madtom will likely benefit
from water quality improvements in portions of the Conasauga River that
are affected by agricultural practices implemented through the WLFW
project.
Synergistic and Cumulative Effects
We note that, by using the SSA framework to guide our analysis of
the scientific information documented in the SSA report, we have not
only analyzed individual effects on the species, but we have also
analyzed their potential cumulative effects. We incorporate the
cumulative effects into our SSA analysis when we characterize the
current and future condition of the species. Our assessment of the
current and future conditions encompasses and incorporates the threats
individually and primary threats cumulatively. Our current and future
condition (see below) assessment is iterative, because it accumulates
and evaluates the effects of all the 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.
In addition to impacting frecklebelly madtom individually, it is
possible that several of the above summarized risk factors are acting
synergistically or cumulatively on the species. The combined impact of
multiple stressors is likely more harmful than a single stressor acting
alone. The dual stressors of climate change and direct human impact
have the potential to affect aquatic ecosystems by altering stream
flows and nutrient cycles, eliminating habitats, and changing community
structure (Moore et al. 1997, p. 942). Increased water temperatures and
a reduction in stream flow are the climate change effects that are most
likely to affect stream communities (Poff 1997, entire), and each of
these variables is strongly influenced by land use patterns. For
example, in agricultural areas, lower precipitation may trigger
increased irrigation resulting in reduced stream flow (Backlund et al.
2008, pp. 42-43). In forested areas, trees influence instream
temperatures through the direct effects of shading. Reductions in
temperature by vegetative cover may be particularly important in low-
order streams, where canopy vegetation significantly reduces the
magnitude and
[[Page 74061]]
variation of the stream temperature compared with that of clear-cut
areas (Ringler and Hall, 1975, pp. 111-121).
Future Scenarios
To evaluate the future viability of the frecklebelly madtom and
address uncertainty associated with the degree and extent of potential
future stressors and their impacts to the madtom, we analyzed three
future scenarios and assessed the resiliency, representation, and
redundancy of the madtom for each scenario. We devised these scenarios
by identifying information on the following primary threats that are
anticipated to affect the frecklebelly madtom in the future:
Agriculture and developed land use. We considered projected changes in
agricultural and developed land uses in assessing future resiliency of
each resilience unit for frecklebelly madtom. We assessed these land
uses to understand the future impacts to habitat degradation and
destruction resulting from poor water quality, a primary threat to
frecklebelly madtom. The three scenarios capture the range of
variability in the changing human population footprint on the landscape
and how frecklebelly madtom populations will respond to these changing
conditions. All three scenarios were projected out to the year 2050
(i.e., 30 years), because we were reasonably certain we could forecast
patterns in land-use change and understand how these land uses will
interact with the frecklebelly madtom and its habitat over this time
period given the species' life span.
In our development of future scenarios, we used projected trends in
land use change from two models, the National Land Cover Database
(NLCD) and the Slope, Land use, Excluded, Urban, Transportation and
Hillshade (SLEUTH) model (Jantz et al. 2010, entire). Future
projections for agricultural land use were developed from NLCD data by
calculating a 15-year trend in agricultural land use change between
2001 and 2016 for each resilience unit and converting that to an annual
rate of agricultural land use change for each resilience unit. We used
the annual rate of agricultural land use change to project changes to
30 years from the present. The annual rate of agricultural land use
change was held constant for each resilience unit across all scenarios;
however, the rate of change in agricultural area varied among the
resilience units we evaluated in our analysis. With the exception of
the Alabama River resilience unit, which has an increase in the amount
of agricultural land use over time, we found an overall decline in the
amount of land used for agriculture. This result is consistent with
broader trends that show the amount of agricultural land is declining
with time in the eastern United States (Sayler et al. 2016, p. 12).
For our future developed land use projections, we used the SLEUTH
datasets from the year 2050 (closest to 30 years in the future) and
examined development across resilience units. We then developed three
scenarios that varied development probabilities: (1) Low development,
(2) moderate development, and (3) high development. For the low
development scenario, we considered all areas predicted to be developed
at a greater than 90 percent probability (i.e., only including areas
that are almost certain to be developed); the moderate development
scenario considered all areas to be developed at a greater than 50
percent probability; and the high development scenario considered all
areas to be developed at a greater than 10 percent probability (i.e.,
including the majority of areas with any potential to be developed).
The results of the future projections for agriculture and developed
land use were used to estimate a composite land use score, and then
using a rule set, we categorized future resiliency into high, moderate,
low, unknown, or likely extirpated conditions.
In the low development scenario, the frecklebelly madtom was
projected to have one unit with high resiliency, seven units with
moderate resiliency, one unit with low resiliency, and four units that
are likely extirpated (see table 2, below). In terms of projected
change from current condition, the Buttahatchee River (B4) and Pearl
River (A2) resilience units are projected to decrease in resiliency
from high to moderate. The Etowah River (F3) resilience unit is
projected to become more developed, although the percent of developed
land does not reach a point where a change in resiliency is
anticipated. All other units are projected to retain their current
resiliency under the low development scenario.

\*\ Resiliency determined as unknown since units are known only from eDNA data.
In the moderate development scenario, the frecklebelly madtom was
projected to have one unit with high resiliency, six units with
moderate resiliency, two units with low resiliency, and four units that
are likely extirpated (see table 2, above). In terms of projected
change from current condition, the Buttahatchee River (B4) and Pearl
River (A2) resilience units are projected to decrease in resiliency
from high to moderate. The Etowah River (F3) resilience unit is
projected to become substantially more developed under this scenario,
and, therefore, this unit is projected to decrease in resiliency from
moderate to low. All other units are projected to retain their current
resiliency.
In the high development scenario, the frecklebelly madtom was
projected to
[[Page 74062]]
have one unit with high resiliency, six units with moderate resiliency,
one unit with low resiliency, and five units that are likely extirpated
(see table 2, above). In terms of projected change from current
condition, the Buttahatchee River (B4) and Pearl River (A2) resilience
units are projected to decrease in resiliency from high to moderate.
The Etowah River (F3) resilience unit is projected to become
substantially more developed under this scenario; therefore, this unit
is projected to decrease in resiliency from moderate to low. The
Conasauga River (F1) resilience unit is projected to decrease in
resiliency from low to being likely extirpated as a result of high
levels of both agriculture and developed land uses. All other units are
projected to retain their current resiliency.
In summary, the resiliency of frecklebelly madtom resilience units
are projected to remain similar to the current condition with eight
units having moderate to high resiliency under the low development
scenario (Service 2020, entire). In the moderate and high development
scenarios, seven units are projected to have moderate to high
resiliency; two units are projected to have low resiliency (one unit is
low under current condition) in the moderate development scenario and
one additional unit is projected to be likely extirpated (total of five
units) in the high development scenario. The Pearl River (A)
representation unit continues to be the stronghold for the species, as
resiliency is projected to remain high in the Bogue Chitto (A1)
resilience unit across all scenarios and the Pearl River (A2)
resilience unit is projected to have moderate resiliency across all
scenarios. All extant resilience units in the Upper Tombigbee (B)
representation unit are projected to have moderate resiliency. The
Cahaba River (E1) resilience unit is projected to maintain moderate
resiliency into the future.
Within the Upper Coosa River (F) representation unit, the Etowah
River (F3) resilience unit is projected to become more developed by
2050 under all scenarios; therefore, in the moderate and high
development scenarios, the resiliency is projected to decrease from
moderate to low, making the unit more vulnerable to stochastic events.
The high level of development projected within riparian areas of the
Etowah River (F3) unit will lead to an increase in impervious area,
which could lead to further decreases in water quality and impact the
persistence of frecklebelly madtom. In addition, although the
agricultural trend projects a decrease, the amount of land in
agricultural use is still projected to remain relatively high. High
levels of agriculture and developed land use projections in this unit
drive the projected low resiliency by the year 2050. In the Conasauga
River (F1) resilience unit, developed land use under the high
development scenario is projected to increase, and agriculture and
developed land use are projected to be at relatively high levels by
2050. However, the Conasauga River (F1) resilience unit currently has
low resiliency, and this projected increase in development is
anticipated to further impact resiliency, resulting in likely
extirpation of the frecklebelly madtom from this unit.
Finally, the presence of frecklebelly madtom in the Lower Tombigbee
River (C1), Lower Alabama River (C2), and Coosawattee River (F2)
resilience units is based on recent positive eDNA samples, and these
units have been assessed as having an unknown resiliency. Based on our
assessment of future land use, threat levels from agriculture and
developed land use are projected to be relatively low in the Lower
Tombigbee (C1) and Lower Alabama (C2) resilience units. Thus, if the
species is present, there is no projected increase in threats related
to agriculture or developed land use. In the Coosawattee River (F2)
resilience unit, there is projected to be relatively high amounts of
agricultural and developed land. If the species is present there, this
land use pattern could represent a threat to the individuals occupying
the unit.
Future species' representation is projected to maintain current
levels in the low development scenario, as the only projected changes
in resiliency are two units decreasing from high to moderate
resiliency. Under the moderate and high development scenarios, the
Etowah River (F3) and Conasauga River (F1) units are projected to
decrease in resiliency. Therefore, the Upper Coosa River (F)
representation unit is projected to be vulnerable to extirpation,
resulting in a loss of species' representation. Given this unit occurs
in a unique physiographic province and has populations considered as an
evolutionary significant unit (Neely 2018, pp. 7-10), the projected
loss of this unit would result in a lower level of representation for
the species.
Species redundancy is projected to maintain current levels into the
future under the low and moderate development scenarios, as no
additional resilience units are projected to become extirpated. In the
Upper Coosa River (F) representation unit, two resilience units are
projected to decrease in resiliency under the moderate and high
scenarios. Therefore, frecklebelly madtom in these units are at an
increased risk of extirpation from a catastrophic event. Given the
broad distribution of moderate to high resilience units, it is unlikely
that a catastrophic event would impact the entire species' range.
Determination of Frecklebelly Madtom's 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 ``endangered species'' or
``threatened species.'' 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 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
We have carefully assessed the best scientific and commercial
information available regarding the past, present, and future threats
to the frecklebelly madtom. We considered whether the frecklebelly
madtom is presently in danger of extinction. Our review of the best
available information indicates there are 16 resilience units of
frecklebelly madtom within 6 representation units across the known
historical range in Louisiana, Mississippi, Alabama, Georgia, and
Tennessee. The species was likely more widespread historically in the
Mobile Bay drainage but was extirpated from large river habitats after
the creation of numerous impoundments. Currently, eight resilience
units (62 percent) of frecklebelly madtom have moderate to high
resiliency and are contributing to the viability of the species;
impacts from habitat destruction and modification do not appear to be
affecting the frecklebelly madtom at the population-level for these
resilience units. Five units (38 percent) have low resiliency or are
likely extirpated due to habitat destruction and degradation resulting
from channelization, dams, and
[[Page 74063]]
impoundments, and these units are not currently contributing to the
frecklebelly madtom's viability. Three units have unknown resiliency as
these units have no direct observations of the species and are known
only from eDNA presence surveys. The species is currently extant in
four of the six representation units with at least one resilience unit
having moderate to high resiliency in each of the four representation
units. Given the broad distribution of the species and eight units
across the range having moderate to high resiliency, a single
catastrophic event is not likely to impact the species as a whole.
Therefore, the frecklebelly madtom across its range is currently at a
low risk of extinction from habitat destruction and other stressors.
Thus, we determine that proposing an endangered status for the species
is not appropriate.
We forecasted the viability of the frecklebelly madtom under three
plausible scenarios 30 years into the future (summarized above in
Future Scenarios). We assessed relevant risk factors that may be acting
on the frecklebelly madtom in the future and whether we could make
reliable predictions about these factors and how they may impact the
viability of the species. We assessed how agriculture and developed
land use is projected to influence the viability of the frecklebelly
madtom 30 years in the future (2050). Based on the modeling and
scenarios evaluated, we considered our ability to make reliable
predictions in the future and the uncertainty in how and to what degree
the species could respond to those risk factors in this timeframe.
Based on this information, we determine the appropriate timeframe for
assessing whether this species is likely to become in danger of
extinction in the foreseeable future is 30 years.
Taking into account the impacts of the primary factors influencing
the species in the future (habitat destruction and degradation caused
by agriculture and developed land uses resulting in poor water quality)
and the potential impacts to the species' needs, we project the
frecklebelly madtom will continue to remain resilient to stochastic
events across much of its range. We project that numerous resilience
units will have moderate to high resiliency over the next 30 years
across the broad geographic range of the species, including within the
four currently extant representation units, depending on scenario.
Although two of our scenarios indicated a decline in the number of
resilience units contributing to viability of the frecklebelly madtom,
eight units in the low development scenario and seven units in the
moderate and high development scenarios are projected to remain viable
through 2050. With the projected lower resiliency from habitat
destruction and degradation within the Upper Coosa River (F)
representation unit, the species' representation and redundancy is
lower than current levels. However, the geographically wide
distribution of resilience and representation units guards against
catastrophic losses rangewide. We find the multiple resilience units
across multiple representation units provide resiliency,
representation, and redundancy levels that are likely sufficient to
sustain the species into the foreseeable future. Therefore, we find
that the risk of extinction of the frecklebelly madtom is sufficiently
low that it is unlikely to become endangered within the foreseeable
future, i.e., within the next 30 years.
After evaluating threats to the species and assessing the
cumulative effect of the threats under the section 4(a)(1) factors, we
conclude that the risk factors acting on the frecklebelly madtom and
its habitat, either singly or in combination, are not of sufficient
imminence, scope, or magnitude to rise to the level to indicate that
the species is in danger of extinction now (an endangered species), or
likely to become endangered within the foreseeable future (a threatened
species), 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. Having determined that the frecklebelly madtom is not in
danger of extinction or likely to become so in the foreseeable future
throughout all of its range, we now consider whether it may be in
danger of extinction or likely to become so in the foreseeable future
in a significant portion of its range--that is, whether there is any
portion of the species' range for which it is true that both (1) the
portion is significant; and (2) the species is in danger of extinction
now or likely to become so in the foreseeable future 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.
In undertaking this analysis for the frecklebelly madtom, we chose
to address the status question first--we consider information
pertaining to the geographic distribution of both the species and the
threats that the species faces to identify any portions of the range
where the species is endangered or threatened. We considered whether
any of the threats acting on the frecklebelly madtom are geographically
concentrated in any portion of the range at a biologically meaningful
scale.
We identified two portions of the species' range that may be
experiencing a concentration of threats. First, the Upper Tombigbee
River (B) representation unit of the frecklebelly madtom may be
experiencing elevated threats resulting from construction of the Tenn-
Tom Waterway (Factor A). The construction of the Tenn-Tom Waterway for
commercial navigation eliminated suitable habitat for the frecklebelly
madtom and has caused the likely extirpation of two of six resilience
units in the Upper Tombigbee River (B) representation unit: Upper
Tombigbee River (B6) and Bull Mountain Creek (B5). We evaluated current
status information and concluded that the species is effectively
extirpated from these two resilience units. Because we considered these
extirpated units to be lost historical range, they cannot be considered
as a significant portion of the range. However, we considered the
effects that the loss of these two units have on the current and future
viability of the frecklebelly madtom in the Upper Tombigbee River (B)
representation unit. We then considered the current status of the
remaining four resilience units in the Upper Tombigbee River
representation unit (B), which currently have moderate to high
resiliency, including the Buttahatchee River (B4)--considered a
stronghold for the species. In addition, the East Fork Tombigbee River
(B1) resilience unit has moderate resiliency with recent collections of
over 100 individuals despite some habitat impacts from the Tenn-Tom
Waterway. These four units are projected to have continued moderate
resiliency into the foreseeable future. Based on these facts, we
conclude that the impacts from the Tenn-Tom Waterway are not having any
biologically meaningful effect on the remaining four resilience units
in the Upper Tombigbee River representation unit (B), which indicates
the species does not have a different status in that portion of its
range. Therefore, even if the Upper Tombigbee River (B) representation
unit was found to
[[Page 74064]]
comprise a significant portion of the frecklebelly madtom's range, we
conclude that the species is not in danger of extinction or likely to
become so in the foreseeable future in that portion.
We identified another portion, the Upper Coosa River (F)
representation unit, of the frecklebelly madtom's range that is
experiencing a concentration of the following threat, but at a
biologically meaningful scale: Habitat destruction and degradation from
agriculture and developed land uses resulting in poor water quality
(Factor A). Currently, within the Upper Coosa River (F) representation
unit, two resilience units (Conasauga River (F1) and Etowah River (F3))
have low and moderate resiliency, respectively; the Coosawattee (F2)
resilience unit was determined to have an unknown resiliency as the
species was not historically known to occur in this river, but eDNA for
the frecklebelly madtom was found in portions of this unit in 2018.
Declines from historical condition in frecklebelly madtom occurrences
have been apparent in the Conasauga River (F1) resilience unit, while
occurrence records in the Etowah River (F3) resilience unit are fairly
widespread and considered similar to historical occurrence records.
Given the current resiliency of units within the Upper Coosa River (F)
representation unit, it is not likely a single catastrophic event would
result in the extirpation of the species from this portion.
In the foreseeable future, we project the Upper Coosa River (F)
representation unit will have declines in resiliency for both the
Conasauga River (F1) and Etowah River (F3) resilience units due to
habitat destruction and degradation from agriculture and developed land
use. Although this threat is not unique to the Upper Coosa River (F)
representation unit, the threat in this portion is great enough to
project a reduction in resiliency for both of these resilience units,
and, therefore, the entire representation unit is expected to decline.
In the Etowah River (F3) resilience unit, urbanization under the low,
moderate, and high development scenarios is projected to increase and
comprise 35, 38, and 42 percent of the watershed, respectively, as
compared to 14 percent of the watershed currently. Within the Conasauga
River (F1) resilience unit, urbanization is projected to increase and
comprise 13, 15, and 17 percent of the watershed under the low,
moderate, and high development scenarios, as compared to 8 percent of
the watershed currently. This projected urbanization coupled with
continued agricultural activities will continue to impair, and
potentially further decrease, stream habitat and water quality in the
Conasauga River (F1) resilience unit, which already has elevated
nitrogen, phosphorus, turbidity, and concentrations of bioavailable
estrogen (Freemen et al. 2017, pp. 429-430). In addition, the future
scenarios project the Etowah River (F3) and Conasauga River (F1) units
to have low resiliency (under the moderate development scenario) and to
have low resiliency and be likely extirpated, respectively (under the
high development scenario), by the year 2050. This would significantly
increase the risk of extirpation of the Upper Coosa (F) representation
unit from a catastrophic or stochastic event. Our examination leads us
to find that there is substantial information that the Upper Coosa
River (F) representation unit is likely to become in danger of
extinction within the foreseeable future.
We then proceeded to consider whether this portion of the range
(i.e., the Upper Coosa River (F) representation unit) is significant.
For the purposes of this analysis, the Service is considering
significant portions of the range by applying any reasonable definition
of ``significant.'' We asked whether any portions of the range may be
biologically meaningful in terms of the resiliency, redundancy, or
representation of the entity being evaluated. This approach is
consistent with the Act, our implementing regulations, our policies,
and case law.
We evaluated the available information about the portion of the
species that occupies the Upper Coosa River representation unit,
assessing its significance. Throughout most of its range, the
frecklebelly madtom occurs in rivers within the Gulf Coastal Plain
physiographic province, which is an area comprising the former
continental shelf and is currently above sea level (Fennemann 1928, p.
280). The Upper Coosa River (F) representation unit occurs in the Ridge
and Valley (Conasauga River (F1) and Coosawattee River (F2) resilience
units) and Piedmont Upland (Etowah River (F3) resilience unit)
physiographic provinces. Physiographic provinces are regions divided
into distinctive geographic areas based on physical geography, such as
topography, soil type, and geologic history (Fenneman 1928, pp. 266-
272), where areas with similar characteristics are grouped into a
province. The Piedmont province contains lowlands (plains) and
highlands (plateaus) with isolated mountains, and in Georgia, the
elevation reaches up to 480 meters (1,500 feet) (Fennemann 1928, p.
293); the Ridge and Valley province contain a longitudinal series of
valleys (lowlands) and ridges (mountains) through the Appalachians
(Fennemann 1928, p. 296). Given the Upper Coosa River (F)
representation unit occurs in different physiographic provinces with a
distinctive physical geography from the rest of the range, frecklebelly
madtoms in this unit may experience environmental conditions, such as
soils, water chemistry, hydrological regimes, and nutrient cycling,
that are different from the rest of the range. These rivers in the
Upper Coosa River (F) representation unit, flowing through unique
physiographic provinces, are also removed from the nearest Coastal
Plain physiographic province resilience units by approximately 418
river miles (673 river kilometers) and represent the most eastern and
northern resilience units of the frecklebelly madtom.
Historically and currently, the Upper Coosa River (F)
representation unit represents a small portion (less than 15 percent
based on current occurrences and occupied stream reaches; less than 24
percent based on historical occurrences) of the frecklebelly madtom's
range. If the Upper Coosa River (F) representation unit was extirpated,
the frecklebelly madtom would lose some representation and redundancy,
but the loss of this portion of the species' range would still leave
sufficient resiliency (populations with moderate to high resiliency),
redundancy, and representation in the remainder of the species' range
such that it would not notably reduce the viability of the species.
Therefore, despite the Upper Coosa River (F) representation unit
occurring in different physiographic provinces and being disjunct from
the remainder of the range, this unit only represents a small portion
of the frecklebelly madtom's historical and current range and does not
represent a significant portion of the frecklebelly madtom's range. We
conclude that the frecklebelly madtom is not in danger of extinction or
likely to become so in the foreseeable future in a significant portion
of its range. Our approach is consistent with the courts' holdings in
Desert Survivors v. Department of the Interior, 321 F. Supp. 3d 1011
(N.D. Cal. 2018), and Center for Biological Diversity v. Jewell, 248 F.
Supp. 3d, 946, 959 (D. Ariz. 2017).
We have carefully assessed the best scientific and commercial
information available regarding the past, present, and future threats
to the frecklebelly madtom. Because the species is neither in danger of
extinction now nor likely to become so in the foreseeable future
throughout all or any significant portion of its range, the
frecklebelly madtom does not meet the definition of an
[[Page 74065]]
endangered species or threatened species. Therefore, we find that
listing the frecklebelly madtom as an endangered or threatened species
under the Act is not warranted at this time. This constitutes the
conclusion of the Service's 12-month finding on the 2010 petition to
list the frecklebelly madtom as an endangered or threatened species. A
detailed discussion of the basis for this finding can be found in the
SSA report and other supporting documents (available on the internet at
https://www.regulations.gov under Docket No. FWS-R4-ES-2020-0058).
We ask the public to submit to us any new information that becomes
available concerning the taxonomy, biology, ecology, or status of the
frecklebelly madtom, or stressors to the frecklebelly madtom, whenever
it becomes available. Please submit any new information, materials,
comments, or questions concerning this finding to the Alabama
Ecological Services Field Office (see FOR FURTHER INFORMATION CONTACT).
Distinct Population Segment (DPS) Analysis
Under the Act, we have the authority to consider for listing any
species, subspecies, or, for vertebrates, any distinct population
segment (DPS) of these taxa if there is sufficient information to
indicate that such action may be warranted. To guide the implementation
of the DPS provisions of the Act, we and the National Marine Fisheries
Service (National Oceanic and Atmospheric Administration--Fisheries),
published the Policy Regarding the Recognition of Distinct Vertebrate
Population Segments Under the Endangered Species Act (DPS Policy) in
the Federal Register on February 7, 1996 (61 FR 4722). Under our DPS
Policy, we use two elements to assess whether a population segment
under consideration for listing may be recognized as a DPS: (1) The
population segment's discreteness from the remainder of the species to
which it belongs, and (2) the significance of the population segment to
the species to which it belongs. If we determine that a population
segment being considered for listing is a DPS, then the population
segment's conservation status is evaluated based on the five listing
factors established by the Act to determine if listing it as either
endangered or threatened is warranted.
The Upper Coosa River (F) representation unit consists of the
Conasauga River, Coosawattee River, Etowah River, and their tributaries
and watersheds (see figure 1, below). The Coosawattee River joins the
Conasauga River to form the Oostanaula River, and the Etowah River
joins the Oostanaula River to form the Coosa River. Within this
proposed rule, we refer to the Upper Coosa River (F) representation
unit as including all rivers and streams in the upper Coosa River basin
that join to form the Coosa River; in other words, the entire watershed
upstream from the confluence of the Oostanaula and Etowah Rivers.
Below, we evaluated the Upper Coosa River representation unit of the
frecklebelly madtom's range to determine whether it meets the
definition of a DPS under our DPS Policy.

Discreteness
Under our DPS Policy, a population segment of a vertebrate taxon
may be considered discrete if it satisfies either one of the following
conditions: (1) It is markedly separated from other populations of the
same taxon as a consequence of physical, physiological, ecological, or
behavioral factors. Quantitative measures of genetic or morphological
discontinuity may provide evidence of this separation; or (2) it is
delimited by international governmental boundaries within which
differences in control of exploitation, management of habitat,
conservation status, or regulatory mechanisms exist that are
significant in light of section 4(a)(1)(D) of the Act.
[[Page 74067]]
The Upper Coosa River (F) representation unit of the frecklebelly
madtom is markedly separate from other representation and resilience
units of the species both genetically and geographically. In terms of
morphology and genetics, the frecklebelly madtom has exhibited some
morphological and genetic differences across representation units.
Preliminary data suggested there was considerable morphological
variation across the species' range, and the populations in the Coosa
River drainage were the most distinctive population (Neely 2018, p. 1).
Given this information, it was thought that frecklebelly madtoms in the
Conasauga and Etowah Rivers may be distinct from frecklebelly madtoms
found elsewhere. Through a reanalysis of existing morphological and
genetic data, frecklebelly madtoms collected from the Coosa River
drainage were found to have shorter snout to barbel midpoint distance
measurements than madtoms collected from other drainages, but this
difference was not diagnostic of this population as there is overlap in
the range of measurements among populations (Neely 2018, p. 7). In
terms of genetic variation, considerable genetic differentiation was
observed among the Pearl, Tombigbee, Cahaba, and Coosa Rivers
populations; however, morphological variation was incongruent with
genetic variation (Neely 2018, p. 10). These results ``do not allow
clear diagnosis of distinct species within Noturus munitus'' (Neely
2018, p. 10). Because the data do not support the description of a
distinct subspecies or species, each population of frecklebelly madtom
is recommended to be considered as a separate evolutionary significant
unit or ESU of the frecklebelly madtom (Neely 2018, p. 10). Therefore,
the Upper Coosa River (F) representation unit is considered an ESU of
the frecklebelly madtom, which provides key representation for the
frecklebelly madtom as a whole.
The Upper Coosa River (F) representation unit also consists of
separate and distinct physiographic provinces as compared to the
majority of the species' range, as discussed above under Status
Throughout a Significant Portion of Its Range. In terms of physical or
geographic separation, the resilience units in the Upper Coosa River
(F) representation unit are disjunct from other units of the
frecklebelly madtom across the species' range. The distance of the
geographic separation from other frecklebelly madtom representation and
resilience units is approximately 418 river miles (673 river
kilometers) upstream with seven dams (Weiss, H. Neely Henry, Logan
Martin, Lay, Mitchell, Jordan, and R.F. Henry) and impoundments
disrupting the connectivity and creating barriers to movement to the
rest of the range. Therefore, frecklebelly madtoms in the Upper Coosa
River (F) representation unit currently do not, and will likely never,
naturally interact with individuals or populations in the remaining
part of the range. In addition, if this portion becomes extirpated,
frecklebelly madtoms located within the Coastal Plain physiographic
province may be unable to recolonize the Upper Coosa River (F)
representation unit, not only due to the lack of connectivity, but also
because they may lack the needed adaptive traits to survive in these
different physical geographies. Based on our review of the available
information, we conclude that the Upper Coosa River representation unit
of the frecklebelly madtom is markedly separate from other
representation and resilience units of the species due to genetic
separation and geographic (physical) isolation from frecklebelly
madtoms in the remainder of the range. Therefore, we have determined
that the Upper Coosa River representation unit of the frecklebelly
madtom meets the condition for discreteness under our DPS Policy.
Significance
Under our DPS Policy, once we have determined that a population
segment is discrete, we consider its biological and ecological
significance to the larger taxon to which it belongs. This
consideration may include, but is not limited to: (1) Evidence of the
persistence of the discrete population segment in an ecological setting
that is unusual or unique for the taxon, (2) evidence that loss of the
population segment would result in a significant gap in the range of
the taxon, (3) evidence that the population segment represents the only
surviving natural occurrence of a taxon that may be more abundant
elsewhere as an introduced population outside its historical range, or
(4) evidence that the discrete population segment differs markedly from
other populations of the species in its genetic characteristics. Of
particular note, as we explained in our draft (76 FR 76987, December 9,
2011, p. 76998) and final (79 FR 37577, July 1, 2014, pp. 79 FR 37579,
37585) Policy on Interpretation of the Phrase ``Significant Portion of
Its Range'' in the Endangered Species Act's Definitions of ``Endangered
Species'' and ``Threatened Species'' (SPR Policy), the definition of
``significant'' for the purpose of significant portion of the range
analysis differs from the definition of ``significant'' found in our
DPS Policy and used for DPS analysis. Although there are similarities
in the definition of ``significant'' under the SPR Policy and the
definition of ``significance'' in the DPS Policy, there are important
differences between the two. The DPS Policy requires that for a
vertebrate population to meet the Act's definition of ``species,'' it
must be discrete from other populations and must be significant to the
taxon as a whole. The significance criterion under the DPS Policy is
necessarily broad and could be met under a wider variety of
circumstances even if it could not be met under the SPR Policy. In this
case, we determine (see below) that the Upper Coosa River (F)
representation unit is ``significant'' for the purposes of DPS, and we
did not, as discussed above, conclude that it constituted a
``significant'' portion of the frecklebelly madtom's range.
Currently, the Upper Coosa River (F) representation unit is one of
four known extant units within the species. We determined that loss of
this unit (population segment) would result in a significant gap in the
species' range. The Upper Coosa River (F) representation unit in
Georgia and Tennessee represents the eastern and northernmost portion
of the frecklebelly madtom's range, with the remainder of the range
occurring in Louisiana, Mississippi, and Alabama. As discussed
previously, this unit also occurs in different physiographic provinces
(Ridge and Valley province and Piedmont Upland province) associated
with different environmental and physical conditions. Lastly, the Upper
Coosa River (F) representation unit is approximately 418 river miles
(673 kilometers) from the nearest resilience units in the Coastal Plain
province. Therefore, the loss of this unit would result in the species'
range shifting south and west approximately 418 miles (673 kilometers).
As with other representation units, the Upper Coosa River (F)
representation unit of the frecklebelly madtom differs markedly from
other populations of the species in its genetic characteristics. As
discussed above, considerable genetic differentiation has been observed
among populations of frecklebelly madtom (Neely 2018, p. 10), and these
populations are considered evolutionary significant units of
frecklebelly madtom. In addition, the Upper Coosa River (F)
representation unit of the frecklebelly madtom persists in different
physiographic provinces than the remainder of the range. The Upper
Coosa River (F) representation unit occurs in the Ridge and Valley
[[Page 74068]]
(Conasauga River (F1) and Coosawattee River (F2) resilience units) and
Piedmont Upland (Etowah River (F3) resilience unit) physiographic
provinces, while the rest of the range occurs in rivers within the Gulf
Coastal Plain physiographic province. Having persisted over time in
areas with distinctive physical geography, frecklebelly madtoms in the
Upper Coosa River (F) representation unit have likely adapted to
environmental conditions, such as soils, water chemistry, hydrological
regimes, and nutrient cycling, differently, as demonstrated by the
divergent genetics described by Neely (2018, entire), and have likely
contributed to the adaptive capacity of the species. The adaptations of
frecklebelly madtoms are an important and unique component of the
species' representation, which is evidence of it differing markedly
from other populations of the species in its genetics. Therefore, we
have substantial evidence that the Upper Coosa River (F) representation
unit of the frecklebelly madtom differs markedly in its genetic
characteristics, as it is considered an evolutionary significant unit,
and loss of this genetic diversity would likely impact the species'
adaptive capacity. However, although the loss of the Upper Coosa River
(F) representation unit would likely result in a reduction in species'
redundancy, and, therefore, the species' adaptive capacity, it would
not notably reduce the viability of the species across the range (see
above under Status Throughout a Significant Portion of Its Range).
Given the evidence that the Upper Coosa River (F) representation
unit of the frecklebelly madtom would result in a significant gap in
the range if lost, and that the unit differs markedly from other
populations of the species, we consider this unit to be significant to
the species as a whole. Thus, the Upper Coosa River (F) representation
unit of the frecklebelly madtom meets the criteria for significance
under our DPS Policy.
DPS Conclusion for the Upper Coosa River Representation Unit of the
Frecklebelly Madtom
Our DPS Policy directs us to evaluate the significance of a
discrete population in the context of its biological and ecological
significance to the remainder of the species to which it belongs. Based
on an analysis of the best available scientific and commercial data, we
conclude that the Upper Coosa River (F) representation unit of the
frecklebelly madtom is discrete due to genetic separation and
geographic (physical) isolation from the remainder of the taxon.
Furthermore, we conclude that the Upper Coosa River representation unit
of the frecklebelly madtom is significant, as described above.
Therefore, we conclude that the Upper Coosa River (F) representation
unit of the frecklebelly madtom is both discrete and significant under
our DPS Policy and is, therefore, a listable entity under the Act.
Based on our DPS Policy (61 FR 4722; February 7, 1996), if a
population segment of a vertebrate species is both discrete and
significant relative to the taxon as a whole (i.e., it is a distinct
population segment), its evaluation for endangered or threatened status
will be based on the Act's definition of those terms and a review of
the factors enumerated in section 4(a) of the Act. Having found that
the Upper Coosa River (F) representation unit of the frecklebelly
madtom meets the definition of a distinct population segment, we now
evaluate the status of this DPS to determine whether it meets the
definition of an endangered or threatened species under the Act.
Status Throughout All of the DPS's Range
In the analysis above for the frecklebelly madtom as a whole, we
have carefully assessed the best scientific and commercial information
available regarding the past, present, and future threats to the Upper
Coosa River DPS of the species. We considered whether the Upper Coosa
River DPS of the frecklebelly madtom is presently in danger of
extinction throughout all of its range. The Upper Coosa River
representation unit faces ongoing and future threats from habitat
destruction and degradation caused by agriculture and developed land
uses resulting in poor water quality. As discussed above under Status
Throughout a Significant Portion of Its Range, occurrence records in
the Etowah River (F3) resilience unit are considered similar to
historical occurrence records, whereas there have been declines from
historical conditions in frecklebelly madtom occurrences in the
Conasauga River (F1) resilience unit. Evidence of the frecklebelly
madtom presence was first reported from the Coosawattee River (F2) from
eDNA collected in 2018. Until eDNA for the species was recorded from
this river, the frecklebelly madtom was not expected occur there, given
that the history of physical modification to improve navigation, as
well as hydropeaking at Carters Dam, upstream has negatively affected
small-bodied, riffle-dwelling fish species (Freeman et al. 2011, pp.
10-11). However, given the current resiliency of units within the Upper
Coosa River (F) representation unit, it is not likely that the current
threats, or the cumulative effects of those threats, will result in the
extirpation of the DPS. Therefore, the DPS is not currently in danger
of extinction throughout its range.
In the future, projected urbanization and continued agricultural
activities will continue to impact the Upper Coosa River DPS and its
habitat by negatively affecting water quality (Factor A). Our future
scenarios project the Etowah River (F3) and Conasauga River (F1) units
in the Upper Coosa River (F) representation unit to have low resiliency
or to become extirpated by the year 2050, and this would significantly
increase the risk of extirpation of the Upper Coosa River (F)
representation unit from the aforementioned threats, as well as a
catastrophic or stochastic event, within the foreseeable future. In our
consideration of foreseeable future, we evaluated how far into the
future we could reliably predict the threats to this unit, as well as
the madtom's response to those threats. Based on the modeling and
scenarios (agriculture and developed land use projections to 2050)
evaluated, we considered our ability to make reliable predictions in
the future and the uncertainty in how and to what degree the unit could
respond to those risk factors in this timeframe. We determined a
foreseeable future of 30 years for the Upper Coosa River representation
unit. Based on this information, we find the Upper Coosa River DPS of
the frecklebelly madtom is likely to become endangered within the
foreseeable future throughout all of its range. Therefore, we consider
the Upper Coosa River DPS to be threatened throughout all of its range.
Status Throughout a Significant Portion of the DPS's 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
in the foreseeable future throughout all or a significant portion of
its range. The court in Center for Biological Diversity v. Everson,
2020 WL 437289 (D.D.C. Jan. 28, 2020) (Center for Biological
Diversity), vacated the aspect of the SPR Policy (79 FR 37577; July 1,
2014) that provided that the Service does not undertake an analysis of
significant portions of a species' range if the species warrants
listing as threatened throughout all of its range. Therefore, we
proceed to evaluating whether the species (DPS) 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
[[Page 74069]]
(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 Center for Biological Diversity,
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 Upper Coosa River DPS
of the frecklebelly madtom, we chose to address the status question
first--we consider information pertaining to the geographic
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 considered whether the threats acting on the Upper Coosa River DPS
are geographically concentrated in any portion of the range at a
biologically meaningful scale. We examine the following threats that
were considered to be primary factors driving current resiliency of the
Upper Coosa River DPS: Habitat destruction and degradation caused by
agriculture and developed land uses resulting in poor water quality
(Factor A).
Habitat destruction and degradation from agriculture and developed
land uses resulting in poor water quality is occurring throughout the
range of the Upper Coosa River DPS. In the Conasauga River (F1)
resilience unit, current development and agriculture comprises 8.0
percent and 21.3 percent of the watershed, respectively (Service 2020,
pp. 66-69). In the Coosawattee River (F2) resilience unit, current
development and agriculture comprises 6.6 percent and 27.2 percent of
the watershed, respectively (Service 2020, pp. 66-69). Lastly, current
development and agriculture comprises 14.8 percent and 10.4 percent of
the Etowah River (F3) resilience unit (Service 2020, pp. 66-69). For
the three resilience units assessed within the DPS, approximately 25 to
33 percent of each unit is currently impacted by agricultural and
developed land uses. Therefore, we found no concentration of threats in
any portion of the Upper Coosa River DPS's range at a biologically
meaningful scale. However, we identified one portion, the Conasauga
River (F1) resilience unit, which currently has low resiliency and
where the frecklebelly madtom has not been observed, despite repeated
surveys, in at least 20 years. Environmental DNA surveys have detected
the frecklebelly madtom in the Conasauga River (F1) resilience unit,
leading us to determine the species remains present there. However, the
lack of recent occurrence data coupled with projections that this unit
will become extirpated within the foreseeable future led us to find
there is substantial information that the Conasauga River (F1)
resilience unit may be endangered.
We then proceeded to consider whether this portion of the range
(i.e., the Conasauga River (F1) resilience unit) is significant. For
purposes of this analysis, the Service is examining for significant
portions of the range by applying any reasonable definition of
``significant.'' We asked whether any portions of the range may be
biologically meaningful in terms of the resiliency, redundancy, or
representation of the entity being evaluated. This approach is
consistent with the Act, our implementing regulations, our policies,
and case law.
The Upper Coosa River (F) representation unit occurs in the Ridge
and Valley (Conasauga River (F1) resilience unit) and Piedmont Upland
(Etowah River (F3) resilience unit) physiographic provinces. As
discussed above under Status Throughout a Significant Portion of Its
Range for the frecklebelly madtom as a whole, physiographic provinces
are geographic areas divided based on physical geography and grouped by
similar characteristics (Fenneman 1928, pp. 266-272). The Conasauga
River (F1) resilience unit occurs in the Ridge and Valley province,
which contains a series of valleys (lowlands) and ridges (mountains)
through the Appalachians (Fennemann 1928, p. 296). The Etowah River
(F3) resilience unit occurs in the Piedmont province, which contains
lowlands (plains) and highlands (plateaus) with isolated mountains
(Fennemann 1928, p. 293). These two resilience units may occur in two
physiographic provinces; however, the geography in both represents
environmental and physical conditions of lowlands and highlands
associated with higher elevations than the remainder of the species'
range in the Coastal Plain province. Frecklebelly madtoms collected in
both the Conasauga River (F1) and Etowah River (F3) resilience units
are strongly associated with river weed (Podostemum spp.) used for
cover and shelter. Neither unit acts as a refugia or an important
spawning ground for the DPS. In addition, the Conasauga River (1)
resilience unit watershed is experiencing similar impacts from
development and agricultural land-use to the Etowah River (F3)
resilience unit. Since the Upper Coosa River DPS of the frecklebelly
madtom occurs in rivers with similar physical and environmental
conditions, and the Conasauga River (F1) resilience unit portion is
experiencing similar water quality impacts as the remainder of the
DPS's range, there is no unique observable environmental usage or
behavioral characteristics attributable to just this portion that would
make it a significant portion of the range of the Upper Coosa River
DPS.
Overall, there is little evidence to suggest that the Conasauga
River (F1) portion of the range has higher quality or higher value
habitat or any other special importance to the species' life history in
the Upper Coosa River DPS. We considered if the Conasauga River (F1)
portion contributes to biological significance in any way listed above
and did not find this portion to be prominent or noteworthy in a manner
that would suggest it is a significant portion of the DPS's range.
Thus, based on the best available information, we find that this
portion of the DPS's range is not biologically significant. Therefore,
no portion of the Upper Coosa River DPS's range provides a basis for
determining that it is in danger of extinction in a significant portion
of its range. This is consistent with the courts' holdings in Desert
Survivors v. Department of the Interior, No. 16-cv-01165-JCS, 2018 WL
4053447 (N.D. Cal. Aug. 24, 2018), and Center for Biological Diversity
v. Jewell, 248 F. Supp. 3d, 946, 959 (D. Ariz. 2017).
Determination of Status
We evaluated threats to the frecklebelly madtom and assessed the
cumulative effect of the threats under the Act's section 4(a)(1)
factors and conclude the species, viewed across its entire range,
experiences a low risk of extinction. Based on the best available
scientific and commercial information as presented in the SSA report
and this finding, we do not find that the frecklebelly madtom is
currently in danger of extinction throughout all or a significant
portion of its range, nor is it likely to become so in the foreseeable
future. However, we did find the Upper Coosa River representation unit
is a valid DPS, and this DPS of the frecklebelly madtom is likely to
become endangered within the foreseeable future throughout all of its
range. Therefore, we propose to list the Upper Coosa River DPS of the
frecklebelly madtom as a threatened species throughout all of its range
in accordance
[[Page 74070]]
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, 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, 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 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 these
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 recovery planning process involves the
identification of actions that are necessary to halt or reverse the
species' decline by addressing the threats to its survival and
recovery. 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.
Recovery planning consists of preparing draft and final recovery
plans, beginning with the development of a recovery outline and making
it available to the public within 30 days of a final listing
determination. The recovery outline guides the immediate implementation
of urgent recovery actions and describes the process to be used to
develop a recovery plan. Revisions of the plan may be done to address
continuing or new threats to the species, as new substantive
information becomes available. The recovery plan also 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. Recovery teams (composed of
species experts, Federal and State agencies, nongovernmental
organizations, and stakeholders) are often established to develop
recovery plans. When completed, the recovery outline, draft recovery
plan, and the final recovery plan will be available on our website
(https://www.fws.gov/endangered), or from our Alabama 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 (e.g., 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.
If 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 Georgia and Tennessee
would be eligible for Federal funds to implement management actions
that promote the protection or recovery of the Upper Coosa River DPS of
the frecklebelly madtom. Information on our grant programs that are
available to aid species recovery can be found at: https://www.fws.gov/grants.
Although the Upper Coosa River DPS of the frecklebelly madtom is
only proposed for listing under the Act at this time, please let us
know if you are interested in participating in recovery efforts for
this species. 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(a) of the Act requires Federal agencies to evaluate their
actions with respect to any species that is proposed or listed as an
endangered or threatened species and with respect to its critical
habitat, if any is designated. Regulations implementing this
interagency cooperation provision of the Act are codified at 50 CFR
part 402. Section 7(a)(4) of the Act requires Federal agencies to
confer with the Service on any action that is likely to jeopardize the
continued existence of a species proposed for listing or result in
destruction or adverse modification of proposed critical habitat. If a
species is listed subsequently, section 7(a)(2) of the Act requires
Federal agencies to ensure that activities they authorize, fund, or
carry out are not likely to jeopardize the continued existence of the
species or destroy or adversely modify its critical habitat. If a
Federal action may affect a listed species or its critical habitat, the
responsible Federal agency must enter into consultation with the
Service.
Federal agency actions within the species' habitat that may require
conference or consultation or both as described in the preceding
paragraph include management and any other landscape-altering
activities on Federal lands administered, or on private lands seeking
funding by Federal agencies, which may include, but are not limited to,
the USDA U.S. Forest Service, USDA Farm Service Agency, USDA Natural
Resources Conservation Service, and Federal Emergency Disaster Service;
issuance of section 404 Clean Water Act (33 U.S.C. 1251 et seq.)
permits by the U.S. Army Corps of Engineers; and construction and
maintenance of roads or highways by the Federal Highway Administration.
It is our policy, as published in the Federal Register on July 1,
1994 (59 FR 34272), to identify to the maximum extent practicable at
the time a species is listed, those activities that would or would not
constitute a violation of section 9 of the Act. The intent of this
policy is to increase public awareness of the effect of a proposed
listing on proposed and ongoing activities within the range of the
species proposed for listing. The discussion below regarding protective
regulations under section 4(d) of the Act complies with our policy.
II. Proposed Rule Issued 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 he deems
necessary and advisable to provide for the conservation of species
listed as threatened. The U.S. Supreme Court has noted that statutory
language like ``necessary and advisable'' demonstrates a large degree
of deference to the agency (see Webster v. Doe, 486 U.S. 592 (1988)).
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
[[Page 74071]]
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. Thus, the combination of the two sentences of section
4(d) provides the Secretary with wide latitude of discretion to select
and promulgate appropriate regulations tailored to the specific
conservation needs of the threatened species. The second sentence
grants particularly broad discretion to the Service when adopting the
prohibitions under section 9.
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 rules
developed under section 4(d) as a valid exercise of agency authority
where they prohibited take of threatened wildlife or include a limited
taking prohibition (see Alsea Valley Alliance v. Lautenbacher, 2007
U.S. Dist. Lexis 60203 (D. Or. 2007); Washington Environmental Council
v. National Marine Fisheries Service, 2002 U.S. Dist. Lexis 5432 (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 him with regard to the permitted activities for those species. He
may, for example, permit taking, but not importation of such species,
or 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).
Exercising our authority under section 4(d), we have developed a
proposed rule that is designed to address the specific threats and
conservation needs for the Upper Coosa River DPS of the frecklebelly
madtom. Although the statute does not require us to make a ``necessary
and advisable'' finding with respect to the adoption of specific
prohibitions under section 9, we find that this rule as a whole
satisfies the requirement in section 4(d) of the Act to issue
regulations deemed necessary and advisable to provide for the
conservation of the Upper Coosa River DPS of frecklebelly madtom. As
discussed above under Summary of Biological Status and Threats, we have
concluded that the Upper Coosa River DPS is likely to become in danger
of extinction within the foreseeable future primarily due to habitat
destruction and degradation from agriculture and developed land uses
resulting in poor water quality. The provisions of this proposed 4(d)
rule would promote conservation of the Upper Coosa River DPS by
encouraging management of the landscape in ways that meet both
watershed and riparian management purposes and the conservation needs
of the Upper Coosa River DPS. The provisions of this proposed rule are
one of many tools that we would use to promote the conservation of the
Upper Coosa River DPS. This proposed 4(d) rule would apply only if and
when we make final the listing of the Upper Coosa River DPS as a
threatened species.
Provisions of the Proposed 4(d) Rule
This proposed 4(d) rule would provide for the conservation of the
Upper Coosa River DPS by prohibiting the following activities, except
as otherwise authorized or permitted: Import or export (see proposed
Sec. 17.44(ee)(1)(i)); take (see proposed Sec. 17.44(ee)(1)(ii));
possession and other acts with unlawfully taken specimens (see proposed
Sec. 17.44(ee)(1)(iii)); delivery, receipt, transport, or shipment in
interstate or foreign commerce in the course of commercial activity
(see proposed Sec. 17.44(ee)(1)(iv)); and sale or offer for sale in
interstate or foreign commerce (see proposed Sec. 17.44(ee)(1)(v)). We
also include several exceptions to these prohibitions, which along with
the prohibitions are set forth under Proposed Regulation Promulgation,
below.
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, unintentionally, or
incidentally. Protecting the Upper Coosa River DPS of the frecklebelly
madtom from direct forms of take, such as physical injury or killing,
whether incidental or intentional, will help preserve and recover the
remaining populations of the DPS. Therefore, we prohibit intentional
take of frecklebelly madtom, including, but not limited to, capturing,
handling, trapping, collecting, or other activities (see proposed Sec.
17.44(ee)(1)(ii)). Also, as discussed above under Summary of Biological
Status and Threats, habitat destruction and degradation from
agriculture and developed land uses are affecting the status of the
Upper Coosa River DPS. Across the DPS's range, stream and water quality
have been degraded physically by sedimentation, pollution,
contaminants, impoundments, channelization, destruction of riparian
habitat, and loss of riparian vegetation due to agriculture activities
and development within the watershed and riparian areas. Other habitat
or hydrological alteration, such as ditching, draining, stream
diversion, or diversion or alteration of surface or ground water flow,
into or out of the stream will impact the habitat of the DPS.
Therefore, we prohibit actions that result in the incidental take of
the Upper Coosa River DPS by destroying, altering, or degrading the
habitat in the manner described above (see proposed Sec.
17.44(ee)(1)(ii)). Regulating these activities would help preserve the
DPS's remaining populations, slow the rate of population decline, and
decrease synergistic, negative effects from other stressors.
Exceptions to Prohibitions
In addition to certain statutory exceptions from prohibitions,
which are found in sections 9 and 10 of the Act, the proposed 4(d) rule
includes the following exceptions to the prohibitions:
Permitted Activities
We may issue permits to carry out otherwise prohibited activities,
including those described above, involving threatened wildlife under
certain circumstances (see proposed Sec. 17.44(ee)(2)(i)). Regulations
governing permits are codified at 50 CFR 17.32. With regard to
threatened wildlife, a permit may be 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 Act.
There are also certain statutory exemptions from the prohibitions,
which are found in sections 9 and 10 of the Act.
Activities Not Requiring a Permit
We recognize the special and unique relationship 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 the Service in implementing all aspects of the Act.
In
[[Page 74072]]
this regard, section 6 of the Act provides that the Service shall
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 the Service in accordance with section 6(c)
of the Act, who is designated by his or her agency for such purposes,
would be able to conduct activities designed to conserve the Upper
Coosa River DPS that may result in otherwise prohibited take without
additional authorization (see proposed Sec. 17.44(ee)(2)(iii)).
We may allow take of the individuals of the Upper Coosa River DPS
without a permit by any employee or agent of the Service or a State
conservation agency designated by his agency for such purposes and when
acting in the course of his official duties if such action is necessary
to aid a sick, injured or orphaned specimen; dispose of a dead
specimen; or salvage a dead specimen which may be useful for scientific
study (see proposed Sec. 17.44(ee)(2)(ii)). In addition, Federal and
State law enforcement officers may possess, deliver, carry, transport,
or ship specimens taken in violation of the Act as necessary (see
proposed Sec. 17.44(ee)(2)(v)).
Channel Restoration, Streambank Stabilization, and Other Activities
Channel restoration is used as a technique to restore degraded,
physically unstable streams back to natural, physically stable,
ecologically functioning streams. When done correctly, these projects
reduce, ameliorate, or fix unnatural erosion, head cutting, and/or
sedimentation. Thus, channel restoration projects result in
geomorphically stable stream channels that maintain the appropriate
lateral dimensions, longitudinal profiles, and sinuosity patterns over
time without an aggrading or degrading bed elevation and include stable
riffle-run-pool complexes that consist of silt-free gravel, coarse
sand, cobble, boulders, woody structure, and river weed (Podostemum
spp.). This provision of the proposed 4(d) rule for channel restoration
would promote conservation of the Upper Coosa River DPS by excepting
incidental take resulting from activities that would improve channel
conditions and restore degraded, physically unstable streams or stream
segments (see proposed Sec. 17.44(ee)(2)(iv)(A)). We anticipate these
activities will advance ecological conditions within a watershed to a
more natural state that will benefit the frecklebelly madtom.
Streambank stabilization is used as a habitat restoration technique
to restore degraded and eroded streambanks back to natively vegetated,
stable streambanks. When done correctly, these projects reduce bank
erosion and instream sedimentation, resulting in improved habitat
conditions for aquatic species. Therefore, we would allow streambanks
to be stabilized using the following bioengineering methods: Live
stakes (live, vegetative cuttings inserted or tamped into the ground in
a manner that allows the stake to take root and grow), live fascines
(live branch cuttings, usually willows, bound together into long,
cigar-shaped bundles), planting of bare-root seedlings or brush
layering (cuttings or branches of easily rooted tree species layered
between successive lifts of soil fill). All methods should use plant
species native to the region where the project is being conducted.
These methods would not include the sole use of quarried rock (rip-rap)
or the use of rock baskets or gabion structures, but could be used in
conjunction with the above bioengineering methods. This provision of
the proposed 4(d) rule for streambank stabilization would promote
conservation of the Upper Coosa River DPS by excepting from the
prohibition incidental take resulting from activities that would
improve habitat conditions by reducing bank erosion and instream
sedimentation (see proposed Sec. 17.44(ee)(2)(iv)(B)).
Improving watershed, riparian, and habitat conditions within the
range of the Upper Coosa River DPS would provide for the conservation
of the DPS and would likely increase resiliency in the Etowah River and
Conasauga River resilience units. Activities carried out under the
Working Lands for Wildlife (WLFW) program of the Natural Resources
Conservation Service (NRCS), U.S. Department of Agriculture, or similar
projects, which may include projects funded by the Service's Partners
for Fish and Wildlife Program or the Environmental Protection Agency's
319 grant program, would benefit the DPS if they do not alter habitats
known to be used by the DPS beyond its tolerances and are implemented
with a primary objective of improving environmental conditions to
support the aquatic biodiversity of flowing water habitats. This
provision of the proposed 4(d) rule for other activities would promote
conservation of the Upper Coosa River DPS by excepting from the
prohibition incidental take resulting from activities as described
above (see proposed Sec. 17.44(ee)(2)(iv)(C)).
Relation of 4(d) Rule to Available Conservation Measures
Nothing in this proposed 4(d) rule would 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 Upper Coosa River DPS. However, interagency
cooperation may be further streamlined through planned programmatic
consultations for the species between Federal agencies and the Service,
where appropriate. We ask the public, particularly State agencies and
other interested stakeholders that may be affected by the proposed 4(d)
rule, to provide comments and suggestions regarding additional guidance
and methods that the Service could provide or use, respectively, to
streamline the implementation of this proposed 4(d) rule (see
Information Requested, above).
Since we are proposing a threatened status for the Upper Coosa
River DPS of the frecklebelly madtom and this proposed rule outlines
the protections in section 9(a)(1) of the Act for the DPS, we are
identifying those activities that would or would not constitute a
violation of either section 9(a)(1) or this proposed 4(d) rule. Based
on the best available information, at this time, activities identified
as discussed above under Exceptions to Prohibitions would not be
considered to result in a violation of section 9 of the Act. On the
other hand, based on the best available information, the following
actions may potentially result in a violation of section 9 of the Act
if we adopt this proposed rule; this list is not comprehensive:
(1) Unauthorized handling, collecting, possessing, selling,
delivering, carrying, or transporting of the frecklebelly madtom,
including interstate transportation across State lines and import or
export across international boundaries.
(2) Destruction/alteration of the species' habitat by discharge of
fill material, draining, ditching, tiling, pond construction, stream
channelization or diversion, or diversion or alteration of surface or
ground water flow into or out of the stream (i.e., due to roads,
impoundments, discharge pipes, stormwater detention basins, etc.).
(3) Introduction of nonnative species that compete with or prey
upon the frecklebelly madtom.
(4) Discharge of chemicals or fill material into any waters in
which the frecklebelly madtom is known to occur.
[[Page 74073]]
Questions regarding whether specific activities would constitute a
violation of section 9 of the Act should be directed to the Alabama
Ecological Services Field Office (see FOR FURTHER INFORMATION CONTACT).
III. Critical Habitat
Background
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 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. Designation also does not allow the government
or public to access private lands, nor does designation require
implementation of restoration, recovery, or enhancement measures by
non-Federal landowners. Where a landowner requests Federal agency
funding or authorization for an action that may affect a listed species
or critical habitat, the Federal agency would be required to consult
with the Service under section 7(a)(2) of the Act. However, even if the
Service were to conclude that the proposed activity would 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 and commercial data available, those physical or biological
features that are essential to the conservation of the species (such as
space, food, cover, and protected habitat). In identifying those
physical or biological features that occur in specific occupied areas,
we focus on the specific features that are essential to support the
life-history needs of the species, including, but not limited to, water
characteristics, soil type, geological features, prey, vegetation,
symbiotic species, or other features. A feature may be a single habitat
characteristic or a more complex combination of habitat
characteristics. Features may include habitat characteristics that
support ephemeral or dynamic habitat conditions. Features may also be
expressed in terms relating to principles of conservation biology, such
as patch size, distribution distances, and connectivity.
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. When designating critical habitat, the Secretary will first
evaluate areas occupied by the species. The Secretary will only
consider unoccupied areas to be essential where a critical habitat
designation limited to geographical areas occupied by the species would
be inadequate to ensure the conservation of the species. In addition,
for an unoccupied area to be considered essential, the Secretary must
determine that there is a reasonable certainty both that the area will
contribute to the conservation of the species and that the area
contains one or more of those physical or biological features essential
to 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.
When we are determining which areas should be designated as
critical habitat, our primary source of information is generally the
information from the SSA report and information developed during the
listing process for the species. Additional information sources may
include any generalized conservation strategy, criteria, or outline
that may have been developed for the species; the recovery plan for the
species; articles in peer-reviewed journals; conservation plans
developed by States and counties; scientific status surveys and
studies; biological assessments; other unpublished materials; or
experts' opinions or personal knowledge.
Habitat is dynamic, and species may move from one area to another
over time. We recognize that critical habitat designated at a
particular point in time may not include all of the habitat areas that
we may later determine are necessary for the recovery of the species.
For these reasons, a critical habitat designation does not signal that
habitat outside the designated area is unimportant or may not be needed
for
[[Page 74074]]
recovery of the species. Areas that are important to the conservation
of the species, both inside and outside the critical habitat
designation, will continue to be subject to: (1) Conservation actions
implemented under section 7(a)(1) of the Act; (2) regulatory
protections afforded by the requirement in section 7(a)(2) of the Act
for Federal agencies to ensure their actions are not likely to
jeopardize the continued existence of any endangered or threatened
species; and (3) section 9 of the Act's prohibitions on taking any
individual of the species, including taking caused by actions that
affect habitat. Federally funded or permitted projects affecting listed
species outside their designated critical habitat areas may still
result in jeopardy findings in some cases. These protections and
conservation tools will continue to contribute to recovery of this
species. Similarly, critical habitat designations made on the basis of
the best available information at the time of designation will not
control the direction and substance of future recovery plans, habitat
conservation plans (HCPs), or other species conservation planning
efforts if new information available at the time of these planning
efforts calls for a different outcome.
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 or threatened
species. Our regulations (50 CFR 424.12(a)(1)) state that the Secretary
may, but is not required to, determine that a designation would not be
prudent in the following circumstances:
(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, or threats to the species' habitat stem solely from causes
that cannot be addressed through management actions resulting from
consultations under section 7(a)(2) of the Act;
(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;
(iv) No areas meet the definition of critical habitat; or
(v) The Secretary otherwise determines that designation of critical
habitat would not be prudent based on the best scientific data
available.
As discussed earlier in this document, there is currently no
imminent threat of take attributed to collection or vandalism
identified under Factor B for this species, and identification and
mapping of critical habitat is not expected to initiate any such
threat. In our SSA and proposed listing determination for the Upper
Coosa River DPS of the frecklebelly madtom, we determined that the
present or threatened destruction, modification, or curtailment of
habitat or range is a threat to the Upper Coosa River DPS and that
those threats in some way can be addressed by section 7(a)(2)
consultation measures. The species occurs wholly in the jurisdiction of
the United States, and we are able to identify areas that meet the
definition of critical habitat. Therefore, because none of the
circumstances enumerated in our regulations at 50 CFR 424.12(a)(1) have
been met and because there are no other circumstances the Secretary has
identified for which this designation of critical habitat would be not
prudent, we have determined that the designation of critical habitat is
prudent for the Upper Coosa River DPS.
Critical Habitat Determinability
Having determined that designation is prudent, under section
4(a)(3) of the Act we must find whether critical habitat for the Upper
Coosa River DPS of the frecklebelly madtom is determinable. Our
regulations at 50 CFR 424.12(a)(2) state that critical habitat is not
determinable when one or both of the following situations exist:
(i) Data sufficient to perform required analyses are lacking, or
(ii) The biological needs of the species are not sufficiently well
known to identify any area that meets the definition of ``critical
habitat.'' When critical habitat is not determinable, the Act allows
the Service an additional year to publish a critical habitat
designation (16 U.S.C. 1533(b)(6)(C)(ii)).
We reviewed the available information pertaining to the biological
needs of the Upper Coosa River DPS and habitat characteristics where
this DPS is located. This and other information represent the best
scientific data available and led us to conclude that the designation
of critical habitat is determinable for the Upper Coosa River DPS.
Physical or Biological Features Essential to the Conservation of the
Species
In accordance with section 3(5)(A)(i) of the Act and regulations at
50 CFR 424.12(b), in determining which areas we will designate as
critical habitat from within the geographical area occupied by the
species at the time of listing, we consider the physical or biological
features that are essential to the conservation of the species and that
may require special management considerations or protection. The
regulations at 50 CFR 424.02 define ``physical or biological features
essential to the conservation of the species'' as the features that
occur in specific areas and that are essential to support the life-
history needs of the species, including, but not limited to, water
characteristics, soil type, geological features, sites, prey,
vegetation, symbiotic species, or other features. A feature may be a
single habitat characteristic or a more complex combination of habitat
characteristics. Features may include habitat characteristics that
support ephemeral or dynamic habitat conditions. Features may also be
expressed in terms relating to principles of conservation biology, such
as patch size, distribution distances, and connectivity. For example,
physical features essential to the conservation of the species might
include gravel of a particular size required for spawning, alkali soil
for seed germination, protective cover for migration, or susceptibility
to flooding or fire that maintains necessary early-successional habitat
characteristics. Biological features might include prey species, forage
grasses, specific kinds or ages of trees for roosting or nesting,
symbiotic fungi, or a particular level of nonnative species consistent
with conservation needs of the listed species. The features may also be
combinations of habitat characteristics and may encompass the
relationship between characteristics or the necessary amount of a
characteristic essential to support the life history of the species.
In considering whether features are essential to the conservation
of the species, we may consider an appropriate quality, quantity, and
spatial and temporal arrangement of habitat characteristics in the
context of the life-history needs, condition, and status of the
species. These characteristics include, but are not limited to, space
for individual and population growth and for normal behavior; food,
water, air, light, minerals, or other nutritional or physiological
requirements; cover or shelter; sites for breeding, reproduction, or
rearing (or development) of offspring;
[[Page 74075]]
and habitats that are protected from disturbance.
The Upper Coosa River DPS is a population segment of the
frecklebelly madtom and occurs in the upper Coosa River system in the
Piedmont Upland physiographic province in Georgia and the Ridge and
Valley physiographic province in Georgia and Tennessee. The primary
habitat features that influence the resiliency of the Upper Coosa River
DPS include flowing water, suitable water quality, substrate, cover,
and habitat connectivity. These features are essential to the survival
and reproduction of individuals at all life stages.
As stated above, the frecklebelly madtom occurs in small to large,
swift-flowing rivers consisting of stable riffle-run pool complexes and
with a substrate that consists of silt-free gravel, coarse sand,
cobble, and boulders. The species needs unimpounded flowing water to
successfully reproduce and maintain populations. In addition, streams
must have an adequate flow to maintain instream habitats and
connectivity of streams with the floodplain, which is important to
allow nutrient and sediment exchange for habitat maintenance. Stream
reaches with suitable habitat must be large enough and have
connectivity to support enough frecklebelly madtoms to ensure
individuals can find a mate and reproduce (Service 2020, p. 17). Cover
is an important component of suitable habitat for the frecklebelly
madtom and provides shelter from predators, space to forage, and space
to nest. The species is often found in or near aquatic vegetation, such
as river weed (Podostemum spp.), woody structures, and under large,
flat rocks. In addition, nesting sites for madtoms are typically
cavities under natural material (rocks, logs, empty mussel shells).
Thus, small to large flowing rivers with appropriate substrate, cover,
and connectivity are important for the growth, reproduction, and
survival of the frecklebelly madtom.
The frecklebelly madtom, like other benthic species, is sensitive
to poor water quality (Warren et al. 1997, p. 125) and needs clean,
flowing water to survive. Changes in water chemistry and flow patterns,
resulting in a decrease in water quality and quantity, have detrimental
effects on madtom ecology, because they can render aquatic habitat
unsuitable for occupancy. In addition, the frecklebelly madtom is
intolerant of excessive sedimentation (Shepard 2004, p. 221). The
minimum and maximum standards of water quality and quantity conditions
that are conducive to the presence of frecklebelly madtom is not well
known. However, muddy waterways, lentic streams (still water), and poor
water quality conditions are not desirable for maintaining suitable
habitat for the species. Therefore, appropriate water and sediment
quality are necessary to sustain growth, reproduction, and viability of
the frecklebelly madtom and are essential to the conservation of the
species.
The species is an opportunistic insectivore feeding on a variety of
aquatic insects and larvae, including caddisflies, mayflies,
blackflies, and midges (Miller 1984, p. 9). Seasonal changes found in
diet probably reflect differences in prey availability (Miller 1984, p.
11). Therefore, a diverse and available aquatic macroinvertebrate
assemblage is important to the growth and survival of the frecklebelly
madtom.
More detail of the habitat and life history needs are summarized
above under Background, and a thorough review is available in the SSA
report (Service 2020, entire; available on https://www.regulations.gov
under Docket No. FWS-R4-ES-2020-0058). A summary of the resource needs
of the Upper Coosa River DPS is provided below in table 3.

Summary of Essential Physical or Biological Features
We derive the specific physical or biological features essential to
the conservation of Upper Coosa River DPS of the frecklebelly madtom
from studies of the species' habitat, ecology, and life history as
described above. Additional information can be found in the SSA report
(Service 2020, entire; available on https://www.regulations.gov under
Docket No. FWS-R4-ES-2020-0058). We have determined that the following
physical or biological features are essential to the conservation of
Upper Coosa River DPS of the frecklebelly madtom:
(1) Geomorphically stable, medium to large streams with:
(a) Stable stream channels that maintain lateral dimensions,
longitudinal profiles, and sinuosity patterns over time without an
aggrading or degrading bed elevation; and
(b) Banks with intact riparian cover to maintain stream morphology
and reduce erosion and sediment inputs.
(2) Connected instream habitats that:
(a) Include stable riffle-run pool complexes;
(b) Consist of silt-free gravel, coarse sand, cobble, boulders,
woody structure, and river weed (Podostemum spp.); and
(c) Have abundant cobble, boulders, woody structure, or other
suitable cover used for nesting.
(3) Adequate flows, or a hydrologic flow regime (which includes the
severity, frequency, duration, and seasonality of discharge over time),
necessary to maintain instream habitats and to maintain connectivity of
streams with the floodplain, allowing the exchange of nutrients and
sediment for maintenance of the fish's habitat, food availability, and
ample oxygenated flow for spawning and nesting habitat.
(4) Appropriate water and sediment quality (including, but not
limited to, conductivity; hardness; turbidity; temperature; pH;
ammonia; heavy metals; pesticides; animal waste products; and nitrogen,
phosphorus, and potassium fertilizers) necessary to sustain natural
physiological processes for normal behavior, growth, and viability of
all life stages.
(5) Diversity and availability of aquatic macroinvertebrate prey
items, which include larval midges, mayflies, caddisflies, dragonflies,
and beetles.

Special Management Considerations or Protection
When designating critical habitat, we assess whether the specific
areas within the geographical area occupied by the species at the time
of listing contain features which are essential to the conservation of
the species and which may require special management considerations or
protection. The features essential to the conservation of the Upper
Coosa River DPS may require special management considerations or
protections to reduce the following threats: (1) Urbanization of the
landscape, including (but not limited to) land conversion for urban and
commercial use, infrastructure (roads, bridges, utilities), and urban
water uses (water supply reservoirs, wastewater treatment); (2)
nutrient pollution from agricultural activities that impact water
quantity and quality; (3) significant alteration of water quality; (4)
culvert and pipe installation that creates barriers to movement; (5)
other watershed and floodplain disturbances that release sediments or
nutrients into the water or fill suitable spawning habitat; and (6)
creation of reservoirs that convert permanently flowing streams and/or
streams that hold water into lake or pond-like (lentic) environments.
Management activities that could ameliorate these threats include,
but are not limited to, use of best management practices (BMPs)
designed to reduce sedimentation, erosion, and bank-side destruction;
protection of riparian corridors and suitable spawning habitat;
retention of sufficient canopy cover along banks; moderation of surface
and ground water withdrawals to maintain natural flow regimes;
increased use of stormwater management and reduction of stormwater
flows into the stream systems; placement of culverts or bridges that
accommodate fish passage; and reduction of other watershed and
floodplain disturbances that release sediments, pollutants, or
nutrients into the water.
Criteria Used To Identify Critical Habitat
As required by section 4(b)(2) of the Act, we use the best
scientific data available to designate critical habitat. In accordance
with the Act and our implementing regulations at 50 CFR 424.12(b), we
review available information pertaining to the habitat requirements of
the species and identify specific areas within the geographical area
occupied by the species at the time of listing and any specific areas
outside the geographical area occupied by the species to be considered
for designation as critical habitat. To determine and select
appropriate occupied areas that contain the physical or biological
features essential to the conservation of the species or areas
otherwise essential for the conservation of the Upper Coosa River DPS
of the frecklebelly madtom, we developed a conservation strategy for
the DPS. The goal of the conservation strategy for the Upper Coosa
River DPS of the frecklebelly madtom is to recover the DPS to the point
where the protections of the Act are no longer necessary. The role of
critical habitat in achieving this conservation goal is to identify the
specific areas within the Upper Coosa River DPS's range that provide
essential physical or biological features, without which range-wide
resiliency, redundancy, and representation could not be achieved. We
anticipate that recovery will require continued protection of existing
resilience units and habitats that contribute to the viability of the
DPS, as well as ensuring there are adequate numbers of fish in stable
units and that at least one viable unit occurs in each of the
physiographic provinces (Piedmont Upland and Ridge and Valley). This
will help to ensure that catastrophic events, such as floods, cannot
simultaneously affect all known resilience units of the DPS. Recovery
considerations, such as maintaining existing genetic diversity and
striving for representation of both physiographic provinces in the
DPS's current range, were considered in formulating this proposal.
In developing our conservation strategy for determining which areas
to include as critical habitat for the Upper Coosa River DPS, we
focused on the existing resilience units and habitats that are
presently contributing to the viability or historical units in which
resiliency can be improved such that they contribute to viability of
the species. In summary, we identified streams and rivers that are
both: (1) Currently occupied streams and rivers within the known
historical range of the Upper Coosa River DPS, and (2) those areas that
have retained the physical or biological features identified earlier
that will allow for the maintenance and expansion of existing
populations. For the purposes of the proposed critical habitat
designation, and for areas within the geographic area occupied by the
species at the time of listing, we determined a unit to be occupied if
it contains a recent (i.e., observed in the past 11 years (since 2009))
observation (collection) or eDNA record that supports the presence of
the species. Within those areas, we delineated critical-habitat-unit
boundaries using the following process:
We evaluated habitat suitability of stream and river channels
within the geographical area occupied at the time of listing, and
retained for further consideration those streams that contain one or
more of the physical and biological features to support life-history
functions essential to conservation of the Upper Coosa River DPS. We
determined the end points of river units by evaluating the presence or
absence of appropriate physical and biological features. Our upstream
cutoff points for each stream are located approximately where the
physiographic province that the frecklebelly madtom occupies begins
(where the Conasauga River flows out of the Blue Ridge and into the
Ridge and Valley physiographic province and where the Etowah River
flows out of the Blue Ridge and into the Piedmont Upland physiographic
province) and selected downstream cutoff points that omit areas where
habitat conditions are less favorable for the species (i.e., do not
contain the physical or biological features essential to the
conservation of the DPS).
Based on this analysis, the following rivers meet criteria for
areas occupied by the species at the time of listing: Conasauga River,
Coosawattee River, and Etowah River. These areas include the two
rivers, Conasauga River and Etowah River, known to have been occupied
by the DPS historically. Environmental DNA of the frecklebelly madtom
was detected in the Conasauga River in 2017 and 2018, which meets the
criteria for consideration as an area occupied by the species at the
time of listing. In the Etowah River, occurrence data and eDNA records
from 2018 are available. These two areas meet our conservation strategy
for the frecklebelly madtom. Designating critical habitat of streams in
these two occupied resilience units of the DPS, which occur in both
physiographic provinces and currently contribute to (or are historical
units in which resiliency can be improved to contribute to) the
species' viability, will sufficiently lead to the protection, and
eventual reduction in risk of extirpation, of the DPS. Improving the
resiliency of the resilience units in these two currently occupied
streams will likely increase viability to the point that the
protections of the Act are no longer necessary.
The proposed designation does not include the Coosawattee River,
which is not part of the known historical range of the species.
Environmental DNA of the frecklebelly madtom was detected in the
Coosawattee River in 2018, which meets
[[Page 74077]]
the criteria for consideration as an area occupied by the species at
the time of listing. However, since the Coosawattee River is not part
of the known historical range of the frecklebelly madtom, this area
does not meet our conservation strategy for designating critical
habitat for the species. The conservation strategy focused on areas
within the historical known range of the species. In addition, since
the species has never been directly observed in this river despite
multiple surveys over time, using the best available information, we
determined this area is not a historical unit in which resiliency can
be improved to contribute to the species' viability. Lastly, we
determined that sufficient areas (Conasauga River and Etowah River)
already have been identified within this proposed designation. Should
we receive information during the public comment period that supports
designating as critical habitat areas not included in the proposed
units (see Proposed Critical Habitat Designation, below), we will
reevaluate our current proposal.
We are not currently proposing to designate any areas outside the
geographical area occupied by the Upper Coosa River DPS, because we
have not identified any unoccupied areas that are essential for the
conservation of the species. The protection of the Conasauga River and
Etowah River would sufficiently reduce the risk of extinction, and
improving the resiliency of these currently occupied streams of the DPS
would increase viability to the point that the protections of the Act
are no longer necessary.
Sources of data for this proposed designation of critical habitat
include multiple databases maintained by universities and State
agencies in Tennessee and Georgia, as well as numerous survey reports
on streams throughout the DPS's range. Other sources of available
information on habitat requirements for this species include studies
conducted at occupied sites and published in peer-reviewed articles,
agency reports, and data collected during monitoring efforts (Shepard
et al. 1997, entire; Bennet et al. 2008, entire; Bennet and Kuhajda
2010, entire; Albanese et al. 2018, entire; Service 2020, entire).
Observation and eDNA records were compiled and provided to us by State
partners during the SSA analysis.
When determining proposed critical habitat boundaries, we made
every effort to avoid including developed areas such as lands covered
by buildings, pavement, and other structures because such lands lack
physical or biological features necessary for the Upper Coosa River
DPS. The scale of the maps we prepared under the parameters for
publication within the Code of Federal Regulations may not reflect the
exclusion of such developed lands. Any such lands inadvertently left
inside critical habitat boundaries shown on the maps of this proposed
rule have been excluded by text in the proposed rule and are not
proposed for designation as critical habitat. Therefore, if the
critical habitat is finalized as proposed, a Federal action involving
these lands would not trigger section 7 consultation with respect to
critical habitat and the requirement of no adverse modification unless
the specific action would affect the physical or biological features in
the adjacent critical habitat.
We propose to designate as critical habitat lands that we have
determined are occupied at the time of listing (i.e., currently
occupied) and that contain one or more of the physical or biological
features that are essential to support life-history processes of the
species. Units are proposed for designation based on one or more of the
physical or biological features being present to support the Upper
Coosa River DPS's life-history processes. Some units contain all of the
identified physical or biological features and support multiple life-
history processes. Unit 1 contains only some of the physical or
biological features necessary to support the Upper Coosa River DPS's
particular use of that habitat. Unit 2 contains all of the identified
physical or biological features and supports multiple life-history
processes.
The critical habitat designation is defined by the map or maps, as
modified by any accompanying regulatory text, presented at the end of
this document under Proposed Regulation Promulgation. We include more
detailed information on the boundaries of the critical habitat
designation in the preamble of this document. We will make the
coordinates or plot points or both on which each map is based available
to the public on https://www.regulations.gov at Docket No. FWS-R4-ES-
2020-0058 and on our internet site at https://www.fws.gov/southeast/.
Proposed Critical Habitat Designation
We are proposing to designate approximately 134 river miles (mi)
(216 river kilometers (km)) in two units as critical habitat for the
Upper Coosa River DPS of the frecklebelly madtom. The critical habitat
areas we describe below constitute our current best assessment of areas
that meet the definition of critical habitat for the Upper Coosa River
DPS. The two units are: (1) Conasauga River Unit and (2) Etowah River
Unit. Table 4, below, shows the proposed critical habitat units, land
ownership, and the approximate river miles of each unit. Per State
regulations (Tennessee Code Annotated section 69-1-101 and Georgia Code
section 52-1-31), navigable waters are considered public rights-of-way.
Lands beneath the navigable waters included in this proposed rule are
owned by the States of Tennessee or Georgia. Ownership of lands beneath
nonnavigable waters included in this rule are determined by riparian
land ownership. The riparian land adjacent to the proposed critical
habitat is 85 percent private, 6 percent local, 5 percent State, and 4
percent Federal lands.

[[Page 74078]]
We present brief descriptions of all units, and reasons why they
meet the definition of critical habitat for the Upper Coosa River DPS,
below.
Unit 1: Conasauga River
Unit 1 consists of approximately 51.5 river mi (83 km) of the
Conasauga River beginning at the mouth of Coahulla Creek in Whitfield
and Murray Counties, Georgia, and continuing upstream through Bradley
County, Tennessee, to the mouth of Graham Branch in Polk County,
Tennessee. Unit 1 includes river habitat up to bank full height.
Frecklebelly madtom occupies all river reaches in this unit. Unit 1
contains some of the physical or biological features necessary for the
conservation of the DPS. Unit 1 possesses those characteristics, as
described above under Summary of Essential Physical or Biological
Features, of essential physical or biological features (1), (2), (3),
and (5). Essential physical or biological feature (4) is degraded in
this unit, but with appropriate management and restoration actions,
this physical or biological feature can be restored.
Special management considerations or protection may be required
within Unit 1 to alleviate impacts from stressors that have led to the
degradation of the habitat, including sedimentation, pollutant input,
excess nutrient input, development, and unstable stream banks.
Surrounding land-use practices, including agricultural runoff,
agricultural ditching, and erosion have led to high levels of
sedimentation, siltation, contamination, and nutrient-loading, as well
as destabilized stream banks. Special management considerations related
to agricultural and developed areas that will benefit the habitat in
this unit include, but are not limited to, riparian buffer restoration,
reduced surface and groundwater withdrawals, increased open space in
the watershed, and treating wastewater to the highest level
practicable.
Unit 2: Etowah River
Unit 2 consists of approximately 82.5 river mi (133 km) of the
Etowah River beginning at its confluence with Shoal Creek in Cherokee
County, Georgia, and continuing upstream through Forsyth and Dawson
Counties to approximately 0.5 miles upstream of the Jay Bridge Road
crossing over the Etowah River in Lumpkin County, Georgia. Unit 2
includes river habitat up to bank full height. Frecklebelly madtom
occupies all river reaches in this unit. Unit 2 contains all of the
physical or biological features necessary for the conservation of the
DPS.
Special management considerations or protection may be required
within Unit 2 to alleviate impacts from stressors that are anticipated
to amplify degradation of the habitat, including sedimentation,
pollutant input, excess nutrient input, development, and unstable
stream banks. Increased development, including urban development and
runoff, dam construction and use, and paved and unpaved roads, in the
surrounding watershed and riparian area have led to higher levels of
sedimentation, siltation, contamination, and nutrient-loading, as well
as destabilized stream banks. Special management considerations related
to agricultural and developed areas that will benefit the habitat in
this unit include, but are not limited to, riparian buffer restoration,
reduced surface and groundwater withdrawals, increased open space in
the watershed, and implementing highest levels of treatment of
wastewater practicable.
Effects of Critical Habitat Designation
Section 7 Consultation
Section 7(a)(2) of the Act requires Federal agencies, including the
Service, to ensure that any action they fund, authorize, 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. In
addition, section 7(a)(4) of the Act requires Federal agencies to
confer with the Service on any agency action which is likely to
jeopardize the continued existence of any species proposed to be listed
under the Act or result in the destruction or adverse modification of
proposed critical habitat.
We published a final rule revising the definition of destruction or
adverse modification on August 27, 2019 (84 FR 44976). Destruction or
adverse modification means a direct or indirect alteration that
appreciably diminishes the value of critical habitat as a whole for the
conservation of a listed species.
If a Federal action may affect a listed species or its critical
habitat, the responsible Federal agency (action agency) must enter into
consultation with us. Examples of actions that are subject to the
section 7 consultation process are 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 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.
Compliance with the requirements of section 7(a)(2) is documented
through our issuance of:
(1) A concurrence letter for Federal actions that may affect, but
are not likely to adversely affect, listed species or critical habitat;
or
(2) A biological opinion for Federal actions that may affect, and
are likely to adversely affect, listed species or critical habitat.
When we issue a biological opinion concluding that a project is
likely to jeopardize the continued existence of a listed species and/or
destroy or adversely modify critical habitat, we provide reasonable and
prudent alternatives to the project, if any are identifiable, that
would avoid the likelihood of jeopardy and/or destruction or adverse
modification of critical habitat. We define ``reasonable and prudent
alternatives'' (at 50 CFR 402.02) as alternative actions identified
during consultation that:
(1) Can be implemented in a manner consistent with the intended
purpose of the action,
(2) Can be implemented consistent with the scope of the Federal
agency's legal authority and jurisdiction,
(3) Are economically and technologically feasible, and
(4) Would, in the Service Director's opinion, avoid the likelihood
of jeopardizing the continued existence of the listed species and/or
avoid the likelihood of destroying or adversely modifying critical
habitat.
Reasonable and prudent alternatives can vary from slight project
modifications to extensive redesign or relocation of the project. Costs
associated with implementing a reasonable and prudent alternative are
similarly variable.
Regulations at 50 CFR 402.16 set forth requirements for Federal
agencies to reinitiate formal consultation on previously reviewed
actions. These requirements apply when the Federal agency has retained
discretionary involvement or control over the action (or the agency's
discretionary involvement or control is authorized by law) and,
subsequent to the previous consultation, we have listed a new
[[Page 74079]]
species or designated critical habitat that may be affected by the
Federal action, or the action has been modified in a manner that
affects the species or critical habitat in a way not considered in the
previous consultation. In such situations, Federal agencies sometimes
may need to request reinitiation of consultation with us, but the
regulations also specify some exceptions to the requirement to
reinitiate consultation on specific land management plans after
subsequently listing a new species or designating new critical habitat.
See the regulations for a description of those exceptions.
Application of the ``Destruction or Adverse Modification'' Standard
The key factor related to the destruction or adverse modification
determination is whether implementation of the proposed Federal action
directly or indirectly alters the designated critical habitat in a way
that appreciably diminishes the value of the critical habitat as a
whole for the conservation of the listed species. As discussed above,
the role of critical habitat is to support physical or biological
features essential to the conservation of a listed species and provide
for the conservation of the species.
Section 4(b)(8) of the Act requires us to briefly evaluate and
describe, in any proposed or final regulation that designates critical
habitat, activities involving a Federal action that may violate section
7(a)(2) of the Act by destroying or adversely modifying such habitat,
or that may be affected by such designation.
Activities that the Service may, during a consultation under
section 7(a)(2) of the Act, find are likely to destroy or adversely
modify critical habitat include, but are not limited to:
(1) Actions that would alter the minimum flow or existing flow
regime. Such activities could include, but are not limited to,
impoundment, channelization, water diversion, water withdrawal,
hydropower generation, and flood control. These activities could
eliminate or reduce the habitat necessary for the growth and
reproduction of the Upper Coosa River DPS by altering flows to levels
that would adversely affect the Upper Coosa River DPS's ability to
complete its life cycle.
(2) Actions that would significantly alter water chemistry or
quality. Such activities could include, but are not limited to, release
of chemicals or biological pollutants into the surface water or
connected groundwater at a point source or by dispersed release (non-
point source). These activities could alter water conditions to levels
that are beyond the tolerances of the Upper Coosa River DPS and result
in direct or cumulative adverse effects to individuals and their life
cycles.
(3) Actions that would significantly increase sediment deposition
within the stream channel. Such activities could include, but are not
limited to, excessive sedimentation from livestock grazing, road
construction, channel alteration, and other watershed and floodplain
disturbances. These activities could eliminate or reduce the habitat
necessary for the growth and reproduction of the Upper Coosa River DPS
by increasing the sediment deposition to levels that would adversely
affect the DPS's ability to complete its life cycle.
(4) Actions that would significantly increase eutrophication (the
addition of excessive nutrients that are typically limited in aquatic
environments, such as nitrogen and phosphorus that cause phytoplankton
to proliferate). Such activities could include, but are not limited to,
release of excessive nutrients into the surface water or connected
groundwater at a point source or by dispersed release (non-point
source). These activities could result in excessive nutrients and algae
filling streams and reducing habitat, degrading water quality from
excessive nutrients and algae decay, and decreasing oxygen levels below
the tolerances of the DPS.
(5) Actions that would significantly alter channel morphology or
geometry, or decrease connectivity. Such activities could include, but
are not limited to, channelization, impoundment, road and bridge
construction, mining, dredging, and destruction of riparian vegetation.
These activities may lead to changes in water flows and levels that
would degrade or eliminate the Upper Coosa River DPS and its habitats.
These actions could also lead to increased sedimentation and
degradation in water quality to levels beyond the tolerances of the
DPS.
(6) Actions that result in the introduction, spread, or
augmentation of nonnative aquatic species in occupied stream segments,
or in stream segments that are hydrologically connected to occupied
stream segments, or introduction of other species that compete with or
prey on the Upper Coosa River DPS. Possible actions could include, but
are not limited to, stocking of nonnative fishes and crayfishes, or
other related actions. These activities could introduce parasites or
disease; result in direct predation or direct competition; or affect
the growth, reproduction, and survival of the DPS.
Exemptions
Application of Section 4(a)(3) of the Act
Section 4(a)(3)(B)(i) of the Act (16 U.S.C. 1533(a)(3)(B)(i))
provides that the Secretary shall not designate as critical habitat any
lands or other geographical areas owned or controlled by the Department
of Defense, or designated for its use, that are subject to an
integrated natural resources management plan (INRMP) prepared under
section 101 of the Sikes Act (16 U.S.C. 670a), if the Secretary
determines in writing that such plan provides a benefit to the species
for which critical habitat is proposed for designation. There are no
Department of Defense (DoD) lands within the proposed critical habitat
designation.
Consideration of Impacts Under Section 4(b)(2) of the Act
Section 4(b)(2) of the Act states that the Secretary shall
designate and make revisions to critical habitat on the basis of the
best available scientific data after taking into consideration the
economic impact, national security impact, and any other relevant
impact of specifying any particular area as critical habitat. The
Secretary may exclude an area from critical habitat if he determines
that the benefits of such exclusion outweigh the benefits of specifying
such area as part of the critical habitat, unless he determines, based
on the best scientific data available, that the failure to designate
such area as critical habitat will result in the extinction of the
species. In making the determination to exclude a particular area, the
statute on its face, as well as the legislative history, are clear that
the Secretary has broad discretion regarding which factor(s) to use and
how much weight to give to any factor.
The first sentence in section 4(b)(2) of the Act requires that we
take into consideration the economic, national security, or other
relevant impacts of designating any particular area as critical
habitat. We describe below the process that we undertook for taking
into consideration each category of impacts and our analyses of the
relevant impacts.
Consideration of Economic Impacts
Section 4(b)(2) of the Act and its implementing regulations require
that we consider the economic impact that may result from a designation
of critical habitat. To assess the probable economic impacts of a
designation, we must first evaluate specific land uses or activities
and projects that may occur in the area of the critical habitat. We
then must evaluate the impacts that a specific
[[Page 74080]]
critical habitat designation may have on restricting or modifying
specific land uses or activities for the benefit of the species and its
habitat within the areas proposed. We then identify which conservation
efforts may be the result of the species being listed under the Act
versus those attributed solely to the designation of critical habitat
for this particular species. The probable economic impact of a proposed
critical habitat designation is analyzed by comparing scenarios both
``with critical habitat'' and ``without critical habitat.''
The ``without critical habitat'' scenario represents the baseline
for the analysis, which includes the existing regulatory and socio-
economic burden imposed on landowners, managers, or other resource
users potentially affected by the designation of critical habitat
(e.g., under the Federal listing as well as other Federal, State, and
local regulations). The baseline, therefore, represents the costs of
all efforts attributable to the listing of the species under the Act
(i.e., conservation of the species and its habitat incurred regardless
of whether critical habitat is designated). The ``with critical
habitat'' scenario describes the incremental impacts associated
specifically with the designation of critical habitat for the species.
The incremental conservation efforts and associated impacts would not
be expected without the designation of critical habitat for the
species. In other words, the incremental costs are those attributable
solely to the designation of critical habitat, above and beyond the
baseline costs. These are the costs we use when evaluating the benefits
of inclusion and exclusion of particular areas from the final
designation of critical habitat should we choose to conduct a
discretionary 4(b)(2) exclusion analysis.
For this designation, we developed an incremental effects
memorandum (IEM) considering the probable incremental economic impacts
that may result from the proposed designation. The information
contained in our IEM was then used to develop a screening analysis of
the probable effects of the designation (IEc 2020, entire). The purpose
of the screening analysis is to filter out particular geographic areas
of critical habitat that are already subject to such protections and
are, therefore, unlikely to incur incremental economic impacts. In
particular, the screening analysis considers baseline costs (i.e.,
absent critical habitat designation) and includes probable economic
impacts where land and water use may be subject to conservation plans,
land management plans, best management practices, or regulations that
protect the habitat area as a result of the Federal listing status of
the Upper Coosa River DPS. Ultimately, the screening analysis allows us
to focus on evaluating the specific areas or sectors that may incur
probable incremental economic impacts as a result of the designation.
This screening analysis, combined with the information contained in our
IEM, comprises our draft economic analysis (DEA) of the proposed
critical habitat designation for the Upper Coosa River DPS of the
frecklebelly madtom; our DEA is summarized in the narrative below.
Executive Orders (E.O.s) 12866 and 13563 direct Federal agencies to
assess the costs and benefits of available regulatory alternatives in
quantitative (to the extent feasible) and qualitative terms. Consistent
with the E.O. regulatory analysis requirements, our effects analysis
under the Act may take into consideration impacts to both directly and
indirectly affected entities, where practicable and reasonable. If
sufficient data are available, we assess to the extent practicable the
probable impacts to both directly and indirectly affected entities. As
part of our screening analysis, we considered the types of economic
activities that are likely to occur within the areas likely affected by
the critical habitat designation. In our evaluation of the probable
incremental economic impacts that may result from the proposed
designation of critical habitat for the Upper Coosa River DPS, first we
identified, in the IEM dated June 23, 2020, probable incremental
economic impacts associated with the following categories of
activities: (1) Federal lands management (U.S. Forest Service and U.S.
Army Corps of Engineers); (2) agriculture; (3) development; (4) roadway
and bridgeway construction; (5) dredging, dams, and diversions; (6)
flood control and hydropower; (7) wastewater and chemical discharge;
(8) pesticide use; (9) recreation; (10) conservation and restoration;
and (11) transportation and utilities. We considered each industry or
category individually. Additionally, we considered whether these
activities have any Federal involvement. Critical habitat designation
generally will not affect activities that do not have any Federal
involvement; under the Act, designation of critical habitat only
affects activities conducted, funded, permitted, or authorized by
Federal agencies. In areas where individuals from the Upper Coosa River
DPS are found, Federal agencies already are required to ensure that
their actions are not likely to jeopardize the continued existence of
the DPS under section 7 consultation procedures. If we finalize this
proposed critical habitat designation, consultations to avoid the
destruction or adverse modification of critical habitat would be
incorporated into the existing consultation process.
In our IEM, we attempted to clarify the distinction between the
effects that will result from the species being listed and those
attributable to the critical habitat designation (i.e., difference
between the jeopardy and adverse modification standards) for the Upper
Coosa River DPS's critical habitat. Because the designation of critical
habitat for the Upper Coosa River DPS was proposed concurrently with
the listing, it has been our experience that it is more difficult to
discern which conservation efforts are attributable to the species
being listed and those which will result solely from the designation of
critical habitat. However, the following specific circumstances in this
case help to inform our evaluation: (1) The essential physical or
biological features identified for critical habitat are the same
features essential for the life requisites of the species, and (2) any
actions that would result in sufficient harm or harassment to
constitute jeopardy to the Upper Coosa River DPS would also likely
adversely affect the essential physical or biological features of
critical habitat. The IEM outlines our rationale concerning this
limited distinction between baseline conservation efforts and
incremental impacts of the designation of critical habitat for this
species. This evaluation of the incremental effects has been used as
the basis to evaluate the probable incremental economic impacts of this
proposed designation of critical habitat.
The proposed critical habitat designation for the Upper Coosa River
DPS totals approximately 134 river miles (mi) (216 river kilometers
(km)) in two occupied units in Georgia and Tennessee. In these areas,
any actions that may affect the species would also affect proposed
critical habitat because all designated habitat is occupied. Thus, it
is unlikely that any additional conservation efforts would be
recommended to address the adverse modification standard over and above
those recommended as necessary to avoid jeopardizing the continued
existence of the Upper Coosa River DPS. Therefore, the only additional
costs that are expected in all of the proposed critical habitat
designation are administrative costs. These costs are due to additional
consultation analysis requiring time and resources by both the Federal
action agency and the Service. However, these costs are not expected to
[[Page 74081]]
reach the threshold of ``significant'' under E.O. 12866. We anticipate
a maximum of 10 section 7 consultations annually at a total incremental
cost of less than $11,000 per year.
We are soliciting data and comments from the public on the DEA
discussed above, as well as all aspects of this proposed rule and our
required determinations. During the development of a final designation,
we will consider the information presented in the DEA and any
additional information on economic impacts received during the public
comment period to determine whether any specific areas should be
excluded from the final critical habitat designation under authority of
section 4(b)(2) and our implementing regulations at 50 CFR 424.19. In
particular, we may exclude an area from critical habitat if we
determine that the benefits of excluding the area outweigh the benefits
of including the area, provided the exclusion will not result in the
extinction of this species.
The final decision on whether to exclude any areas will be based on
the best scientific data available at the time of the final
designation, including information we obtain during the public comment
period and information about the economic impact of designation.
Accordingly, we have prepared a draft economic analysis concerning the
proposed critical habitat designation, which is available for review
and comment (see ADDRESSES).
Consideration of National Security Impacts
In preparing this proposal, we have determined that the lands
within the proposed designation of critical habitat for the Upper Coosa
River DPS are not owned, managed, or used by the DoD or DHS where a
national security or homeland security impact might exist, and,
therefore, we anticipate no impact on national security or homeland
security. However, during the development of a final designation, we
will consider any additional information received through the public
comment period on the impacts of the proposed designation on national
security or homeland security to determine whether any specific areas
should be excluded from the final critical habitat designation under
authority of section 4(b)(2) and our implementing regulations at 50 CFR
424.19.
Consideration of Other Relevant Impacts
We consider a number of factors, including whether there are
permitted conservation plans covering the species in the area such as
HCPs, safe harbor agreements (SHAs), or candidate conservation
agreements with assurances (CCAAs), or whether there are non-permitted
conservation agreements and partnerships that would be encouraged by
designation of, or exclusion from, critical habitat. In addition, we
look at the existence of Tribal conservation plans and partnerships and
consider the government-to-government relationship of the United States
with Tribal entities. We also consider any social impacts that might
occur because of the designation.
In preparing this proposal, we have determined that there are
currently no draft or final HCPs or other management plans for the
Upper Coosa River DPS, and the proposed designation does not include
any Tribal lands or trust resources.
As discussed above, we anticipate no impacts on national security,
economic, or any other relevant impacts as a result of this
designation. Accordingly, at this time, we do not propose to exclude
any particular areas from the critical habitat designation. However,
during the development of a final designation, we will consider any
additional information we receive through the public comment period
regarding other relevant impacts to determine whether any specific
areas should be excluded from the final critical habitat designation
under authority of section 4(b)(2) and our implementing regulations at
50 CFR 424.19.
Required Determinations
Clarity of the Rule
We are required by Executive Orders 12866 and 12988 and by the
Presidential Memorandum of June 1, 1998, to write all rules in plain
language. This means that each rule we publish must:
(1) Be logically organized;
(2) Use the active voice to address readers directly;
(3) Use clear language rather than jargon;
(4) Be divided into short sections and sentences; and
(5) Use lists and tables wherever possible.
If you feel that we have not met these requirements, send us
comments by one of the methods listed in ADDRESSES. To better help us
revise the rule, your comments should be as specific as possible. For
example, you should tell us the numbers of the sections or paragraphs
that are unclearly written, which sections or sentences are too long,
the sections where you feel lists or tables would be useful, etc.
Regulatory Planning and Review (Executive Orders 12866 and 13563)
Executive Order 12866 provides that the Office of Information and
Regulatory Affairs (OIRA) in the Office of Management and Budget will
review all significant rules. OIRA has determined that this rule is not
significant.
Executive Order 13563 reaffirms the principles of E.O. 12866 while
calling for improvements in the nation's regulatory system to promote
predictability, to reduce uncertainty, and to use the best, most
innovative, and least burdensome tools for achieving regulatory ends.
The executive order directs agencies to consider regulatory approaches
that reduce burdens and maintain flexibility and freedom of choice for
the public where these approaches are relevant, feasible, and
consistent with regulatory objectives. E.O. 13563 emphasizes further
that regulations must be based on the best available science and that
the rulemaking process must allow for public participation and an open
exchange of ideas. We have developed this proposed rule in a manner
consistent with these requirements.
Regulatory Flexibility Act (5 U.S.C. 601 et seq.)
Under the Regulatory Flexibility Act (RFA; 5 U.S.C. 601 et seq.),
as amended by the Small Business Regulatory Enforcement Fairness Act of
1996 (SBREFA; 5 U.S.C. 801 et seq.), whenever an agency is required to
publish a notice of rulemaking for any proposed or final rule, it must
prepare and make available for public comment a regulatory flexibility
analysis that describes the effects of the rule on small entities
(i.e., small businesses, small organizations, and small government
jurisdictions). However, no regulatory flexibility analysis is required
if the head of the agency certifies the rule will not have a
significant economic impact on a substantial number of small entities.
The SBREFA amended the RFA to require Federal agencies to provide a
certification statement of the factual basis for certifying that the
rule will not have a significant economic impact on a substantial
number of small entities.
According to the Small Business Administration, small entities
include small organizations such as independent nonprofit
organizations; small governmental jurisdictions, including school
boards and city and town governments that serve fewer than 50,000
residents; and small businesses (13 CFR 121.201). Small businesses
include manufacturing and mining concerns with fewer than 500
[[Page 74082]]
employees, wholesale trade entities with fewer than 100 employees,
retail and service businesses with less than $5 million in annual
sales, general and heavy construction businesses with less than $27.5
million in annual business, special trade contractors doing less than
$11.5 million in annual business, and agricultural businesses with
annual sales less than $750,000. To determine whether potential
economic impacts to these small entities are significant, we considered
the types of activities that might trigger regulatory impacts under
this designation as well as types of project modifications that may
result. In general, the term ``significant economic impact'' is meant
to apply to a typical small business firm's business operations.
Under the RFA, as amended, and as understood in the light of recent
court decisions, Federal agencies are required to evaluate the
potential incremental impacts of rulemaking only on those entities
directly regulated by the rulemaking itself and, therefore, are not
required to evaluate the potential impacts to indirectly regulated
entities. The regulatory mechanism through which critical habitat
protections are realized is section 7 of the Act, which requires
Federal agencies, in consultation with the Service, to ensure that any
action authorized, funded, or carried out by the agency is not likely
to destroy or adversely modify critical habitat. Therefore, under
section 7, only Federal action agencies are directly subject to the
specific regulatory requirement (avoiding destruction and adverse
modification) imposed by critical habitat designation. Consequently, it
is our position that only Federal action agencies would be directly
regulated if we adopt the proposed critical habitat designation. There
is no requirement under the RFA to evaluate the potential impacts to
entities not directly regulated. Moreover, Federal agencies are not
small entities. Therefore, because no small entities would be directly
regulated by this rulemaking, the Service certifies that, if made final
as proposed, the proposed critical habitat designation will not have a
significant economic impact on a substantial number of small entities.
In summary, we have considered whether the proposed designation
would result in a significant economic impact on a substantial number
of small entities. For the above reasons and based on currently
available information, we certify that, if made final, the proposed
critical habitat designation will not have a significant economic
impact on a substantial number of small business entities. Therefore,
an initial regulatory flexibility analysis is not required.
Executive Order 13771
This proposed rule is not a regulatory action subject to Executive
Order (E.O.) 13771 (``Reducing Regulation and Controlling Regulatory
Costs'') (82 FR 9339, February 3, 2017) regulatory action because this
rule is not significant under E.O. 12866.
Energy Supply, Distribution, or Use--Executive Order 13211
Executive Order 13211 (Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use) requires
agencies to prepare Statements of Energy Effects when undertaking
certain actions. The Office of Management and Budget (OMB) provides
guidance for implementing this Executive Order, outlining nine outcomes
(criteria) that may constitute ``a significant adverse effect'' when
compared with the regulatory action under consideration. The economic
analysis finds that none of these criteria are relevant to this
analysis, and therefore, we did not find that this proposed critical
habitat designation would significantly affect energy supplies,
distribution, or use. Therefore, this action is not a significant
energy action, and no Statement of Energy Effects is required.
Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.)
In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 1501
et seq.), we make the following finding:
(1) This proposed rule would not produce a Federal mandate. In
general, a Federal mandate is a provision in legislation, statute, or
regulation that would impose an enforceable duty upon State, local, or
Tribal governments, or the private sector, and includes both ``Federal
intergovernmental mandates'' and ``Federal private sector mandates.''
These terms are defined in 2 U.S.C. 658(5)-(7). ``Federal
intergovernmental mandate'' includes a regulation that ``would impose
an enforceable duty upon State, local, or tribal governments'' with two
exceptions. It excludes ``a condition of Federal assistance.'' It also
excludes ``a duty arising from participation in a voluntary Federal
program,'' unless the regulation ``relates to a then-existing Federal
program under which $500,000,000 or more is provided annually to State,
local, and tribal governments under entitlement authority,'' if the
provision would ``increase the stringency of conditions of assistance''
or ``place caps upon, or otherwise decrease, the Federal Government's
responsibility to provide funding,'' and the State, local, or Tribal
governments ``lack authority'' to adjust accordingly. At the time of
enactment, these entitlement programs were: Medicaid; Aid to Families
with Dependent Children work programs; Child Nutrition; Food Stamps;
Social Services Block Grants; Vocational Rehabilitation State Grants;
Foster Care, Adoption Assistance, and Independent Living; Family
Support Welfare Services; and Child Support Enforcement. ``Federal
private sector mandate'' includes a regulation that ``would impose an
enforceable duty upon the private sector, except (i) a condition of
Federal assistance or (ii) a duty arising from participation in a
voluntary Federal program.''
The designation of critical habitat does not impose a legally
binding duty on non-Federal Government entities or private parties.
Under the Act, the only regulatory effect is that Federal agencies must
ensure that their actions do not destroy or adversely modify critical
habitat under section 7. While non-Federal entities that receive
Federal funding, assistance, or permits, or that otherwise require
approval or authorization from a Federal agency for an action, may be
indirectly impacted by the designation of critical habitat, the legally
binding duty to avoid destruction or adverse modification of critical
habitat rests squarely on the Federal agency. Furthermore, to the
extent that non-Federal entities are indirectly impacted because they
receive Federal assistance or participate in a voluntary Federal aid
program, the Unfunded Mandates Reform Act would not apply, nor would
critical habitat shift the costs of the large entitlement programs
listed above onto State governments.
(2) We do not believe that this rule would significantly or
uniquely affect small governments, because it will not produce a
Federal mandate of $100 million or greater in any year, that is, it is
not a ``significant regulatory action'' under the Unfunded Mandates
Reform Act. The designation of critical habitat imposes no obligations
on State or local governments and, as such, a Small Government Agency
Plan is not required.
Takings--Executive Order 12630
In accordance with E.O. 12630 (Government Actions and Interference
with Constitutionally Protected Private Property Rights), we have
analyzed the potential takings implications of designating critical
habitat for Upper Coosa River DPS in a takings
[[Page 74083]]
implications assessment. The Act does not authorize the Service to
regulate private actions on private lands or confiscate private
property as a result of critical habitat designation. Designation of
critical habitat does not affect land ownership, or establish any
closures, or restrictions on use of or access to the designated areas.
Furthermore, the designation of critical habitat does not affect
landowner actions that do not require Federal funding or permits, nor
does it preclude development of habitat conservation programs or
issuance of incidental take permits to permit actions that do require
Federal funding or permits to go forward. However, Federal agencies are
prohibited from carrying out, funding, or authorizing actions that
would destroy or adversely modify critical habitat. A takings
implications assessment has been completed for the proposed designation
of critical habitat for Upper Coosa River DPS, and it concludes that,
if adopted, this designation of critical habitat does not pose
significant takings implications for lands within or affected by the
designation.
Federalism--Executive Order 13132
In accordance with E.O. 13132 (Federalism), this proposed rule does
not have significant Federalism effects. A federalism summary impact
statement is not required. In keeping with Department of the Interior
and Department of Commerce policy, we requested information from, and
coordinated development of this proposed critical habitat designation
with, appropriate State resource agencies. From a federalism
perspective, the designation of critical habitat directly affects only
the responsibilities of Federal agencies. The Act imposes no other
duties with respect to critical habitat, either for States and local
governments, or for anyone else. As a result, the proposed rule does
not have substantial direct effects either on the States, or on the
relationship between the national government and the States, or on the
distribution of powers and responsibilities among the various levels of
government. The proposed designation may have some benefit to these
governments because the areas that contain the features essential to
the conservation of the species are more clearly defined, and the
physical or biological features of the habitat necessary for the
conservation of the species are specifically identified. This
information does not alter where and what federally sponsored
activities may occur. However, it may assist State and local
governments in long-range planning because they no longer have to wait
for case-by-case section 7 consultations to occur.
Where State and local governments require approval or authorization
from a Federal agency for actions that may affect critical habitat,
consultation under section 7(a)(2) of the Act would be required. While
non-Federal entities that receive Federal funding, assistance, or
permits, or that otherwise require approval or authorization from a
Federal agency for an action, may be indirectly impacted by the
designation of critical habitat, the legally binding duty to avoid
destruction or adverse modification of critical habitat rests squarely
on the Federal agency.
Civil Justice Reform--Executive Order 12988
In accordance with Executive Order 12988 (Civil Justice Reform),
the Office of the Solicitor has determined that the rule would not
unduly burden the judicial system and that it meets the requirements of
sections 3(a) and 3(b)(2) of the Order. We have proposed designating
critical habitat in accordance with the provisions of the Act. To
assist the public in understanding the habitat needs of the species,
this proposed rule identifies the elements of physical or biological
features essential to the conservation of the species. The proposed
areas of designated critical habitat are presented on maps, and the
proposed rule provides several options for the interested public to
obtain more detailed location information, if desired.
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)
This rule does not contain information collection requirements, and
a submission to the Office of Management and Budget (OMB) under the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.) is not
required. We may not conduct or sponsor, and you are not required to
respond to, a collection of information unless it displays a currently
valid OMB control number.
National Environmental Policy Act (42 U.S.C. 4321 et seq.)
We have determined that environmental assessments and environmental
impact statements, as defined under the authority of the National
Environmental Policy Act (NEPA), need not be prepared in connection
with listing a species as an endangered or threatened species under the
Act. We published a notice outlining our reasons for this determination
in the Federal Register on October 25, 1983 (48 FR 49244).
It is also our position that, outside the jurisdiction of the U.S.
Court of Appeals for the Tenth Circuit, we do not need to prepare
environmental analyses pursuant to the NEPA in connection with
designating critical habitat under the Act. We published a notice
outlining our reasons for this determination in the Federal Register on
October 25, 1983 (48 FR 49244). This position was upheld by the U.S.
Court of Appeals for the Ninth Circuit (Douglas County v. Babbitt, 48
F.3d 1495 (9th Cir. 1995), cert. denied 516 U.S. 1042 (1996)).
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 Governments), and the Department of the
Interior's manual at 512 DM 2, we readily acknowledge our
responsibility to communicate meaningfully with recognized Federal
Tribes on a government-to-government basis. In accordance with
Secretarial 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. We have identified no Tribal interests
that would be affected by this proposed listing. We have also
determined that no Tribal lands fall within the boundaries of the
proposed critical habitat for the Upper Coosa River DPS, so no Tribal
lands would be affected by the proposed designation.

(1) Prohibitions. The following prohibitions that apply to
endangered wildlife also apply to the Upper Coosa River DPS. Except as
provided under paragraph (ee)(2) of this section and Sec. Sec. 17.4
and 17.5, it is unlawful for any person subject to the jurisdiction of
the United States to commit, to attempt to commit, to solicit another
to commit, or cause to be committed, any of the following acts in
regard to this DPS:
(i) Import or export, as set forth at Sec. 17.21(b) for endangered
wildlife.
(ii) Take, as set forth at Sec. 17.21(c)(1) for endangered
wildlife.
(iii) Possession and other acts with unlawfully taken specimens, as
set forth at Sec. 17.21(d)(1) for endangered wildlife.
(iv) Interstate or foreign commerce in the course of a commercial
activity, as set forth at Sec. 17.21(e) for endangered wildlife.
(v) Sale or offer for sale, as set forth at Sec. 17.21(f) for
endangered wildlife.
(2) Exceptions from prohibitions. In regard to this DPS, you may:
(i) Conduct activities as authorized by a permit under Sec. 17.32.
(ii) Take, as set forth at Sec. 17.21(c)(2) through (c)(4) for
endangered wildlife.
(iii) Take as set forth at Sec. 17.31(b).
(iv) Take incidental to an otherwise lawful activity caused by:
(A) Channel restoration projects that create natural, physically
stable, ecologically functioning streams. These projects can be
accomplished using a variety of methods, but the desired outcome is a
natural channel with geomorphically stable stream channels that
maintain the appropriate lateral dimensions, longitudinal profiles, and
sinuosity patterns over time without an aggrading or degrading bed
elevation and include stable riffle-run-pool complexes that consist of
silt-free gravel, coarse sand, cobble, boulders, woody structure, and
river weed (Podostemum spp.).
(B) Streambank stabilization projects that use bioengineering
methods to replace pre-existing, bare, eroding stream banks with
natively vegetated, stable stream banks, thereby reducing bank erosion
and instream sedimentation and improving habitat conditions for the
DPS. Stream banks may be stabilized using live stakes (live, vegetative
cuttings inserted or tamped into the ground in a manner that allows the
stake to take root and grow), live fascines (live branch cuttings,
usually willows, bound together into long, cigar-shaped bundles), or
brush layering (cuttings or branches of easily rooted tree species
layered between successive lifts of soil fill). Stream banks must not
be stabilized solely through the use of quarried rock (rip-rap) or the
use of rock baskets or gabion structures.
(C) Projects carried out in the DPS's range under the Working Lands
for Wildlife program of the Natural Resources Conservation Service,
U.S. Department of Agriculture, or similar projects conducted by the
U.S. Fish and Wildlife Service Partners for Fish and Wildlife Program
or the Environmental Protection Agency's 319 Grant Program, that are
implemented with a primary objective of improving environmental
conditions to support the native, aquatic biodiversity of flowing water
habitats.

(1) Critical habitat units are depicted for Bradley and Polk
Counties, Tennessee, and Cherokee, Dawson, Forsyth, Lumpkin, Murray,
and Whitfield Counties, Georgia, on the maps in this entry.
(2) Within these areas, the physical or biological features
essential to the conservation of the Upper Coosa River distinct
population segment (DPS) consist of the following components:
(i) Geomorphically stable, medium to large streams with:
(A) Stable stream channels that maintain lateral dimensions,
longitudinal profiles, and sinuosity
[[Page 74085]]
patterns over time without an aggrading or degrading bed elevation; and
(B) Banks with intact riparian cover to maintain stream morphology
and reduce erosion and sediment inputs.
(ii) Connected instream habitats that:
(A) Include stable riffle-run-pool complexes;
(B) Consist of silt-free gravel, coarse sand, cobble, boulders,
woody structure, and river weed (Podostemum spp.); and
(C) Have abundant cobble, boulders, woody structure, or other
suitable cover used for nesting.
(iii) Adequate flows, or a hydrologic flow regime (which includes
the severity, frequency, duration, and seasonality of discharge over
time), necessary to maintain instream habitats and to maintain
connectivity of streams with the floodplain, allowing the exchange of
nutrients and sediment for maintenance of the fish's habitat, food
availability, and ample oxygenated flow for spawning and nesting
habitat.
(iv) Appropriate water and sediment quality (including, but not
limited to, conductivity; hardness; turbidity; temperature; pH;
ammonia; heavy metals; pesticides; animal waste products; and nitrogen,
phosphorus, and potassium fertilizers) necessary to sustain natural
physiological processes for normal behavior, growth, and viability of
all life stages.
(v) Diversity and availability of aquatic macroinvertebrate prey
items, which include larval midges, mayflies, caddisflies, dragonflies,
and beetles.
(3) Critical habitat does not include manmade structures (such as
buildings, aqueducts, runways, roads, and other paved areas) and the
land on which they are located existing within the legal boundaries on
the effective date of the rule.
(4) Critical habitat map units. Data layers defining map units were
selected from the U.S. Geological Survey National Hydrological
Dataset--High Resolution (1:24,000 scale; Geographic Coordinate System
North American 1983 coordinates) using mapping software. The selected
river reaches were informed by species occurrence data. All layers use
Universal Transverse Mercator (UTM) Zone 16N coordinates. We also used
the mapping software to calculate the length of the units. The maps in
this entry, as modified by any accompanying regulatory text, establish
the boundaries of the critical habitat designation. The coordinates or
plot points on which each map is based are available to the public at
the Service's internet site at https://www.fws.gov/southeast/, at
https://www.regulations.gov at Docket No. FWS-R4-ES-2020-0058, and at
the field office responsible for this designation. You may obtain field
office location information by contacting one of the Service regional
offices, the addresses of which are listed at 50 CFR 2.2.
