ACTION: 90-Day petition finding, request
for information, and initiation of status
review.
We, NMFS, announce a 90day finding on a petition to list as
threatened or endangered the Upper
Klamath-Trinity Rivers (UKTR) Chinook
salmon Evolutionarily Significant Unit
(ESU) (Oncorhynchus tshawytscha) or,
alternatively, create a new ESU to
describe Klamath Spring Chinook
salmon and list the new ESU as
threatened or endangered under the
Endangered Species Act (ESA). The
petition also requests that we designate
critical habitat concurrently with the
listing. We find that the petition
presents substantial scientific
information indicating the petitioned
actions may be warranted. We will
conduct a status review of the Chinook
salmon in the UKTR Basin to determine
if the petitioned actions are warranted.
To ensure that the status review is
comprehensive, we are soliciting
scientific and commercial information
pertaining to this species from any
interested party.
DATES: Scientific and commercial
information pertinent to the petitioned
action must be received by April 30,
2018.

SUPPLEMENTARY INFORMATION:
Background
On November 2, 2017, the Secretary
of Commerce received a petition from
the Karuk Tribe and Salmon River
Restoration Council (hereafter, the
Petitioners) to list as threatened or
endangered the UKTR Chinook salmon
ESU or, alternatively, create and list a
new ESU to describe Klamath Spring
Chinook salmon. In their petition, the
Petitioners used various phrases as well
as ‘‘Klamath Spring Chinook’’ to
describe the area in which they are
requesting that we create a new ESU for
spring-run Chinook salmon. Because
their request is generally made in
reference to the spring-run Chinook
salmon component of the UKTR ESU of
Chinook salmon, we will use the
description of the currently defined ESU
to describe the area in which the
Petitioners are requesting that we create
a new spring-run Chinook salmon ESU.
We will hereinafter refer to that area as
the UKTR Basin. We described all
Klamath River Basin populations of
Chinook salmon from the Trinity River
and Klamath River upstream from the
confluence of the Trinity River as the
UKTR ESU, which includes both springrun and fall-run fish (63 FR 11482;
March 9, 1998). The Petitioners also
request designation of critical habitat
concurrently with the listing. Copies of
the petition are available as described
above (see FOR FURTHER INFORMATION
CONTACT).
ESA Statutory, Regulatory, Policy
Provisions, and Evaluation Framework
Section 4(b)(3)(A) of the ESA of 1973,
as amended (16 U.S.C. 1531 et seq.),
requires, to the maximum extent
practicable, that within 90 days of
receipt of a petition to list a species as
threatened or endangered, the Secretary
of Commerce make a finding on whether
that petition presents substantial
scientific or commercial information
indicating that the petitioned action
may be warranted, and to promptly
publish such finding in the Federal
Register (16 U.S.C. 1533(b)(3)(A)). When
it is found that substantial scientific or
commercial information in a petition
PO 00000
Frm 00021
Fmt 4702
Sfmt 4702
8411
indicates the petitioned action may be
warranted (a ‘‘positive 90-day finding’’),
we are required to promptly commence
a review of the status of the species
concerned during which we will
conduct a comprehensive review of the
best available scientific and commercial
information. In such cases, we conclude
the review with a finding as to whether,
in fact, the petitioned action is
warranted within 12 months of receipt
of the petition. Because the finding at
the 12-month stage is based on a more
thorough review of the available
information, as compared to the narrow
scope of review at the 90-day stage, a
‘‘may be warranted’’ finding does not
prejudge the outcome of the status
review.
Under the ESA, a listing
determination may address a species,
which is defined to also include
subspecies and, for any vertebrate
species, any distinct population
segment (DPS) that interbreeds when
mature (16 U.S.C. 1532(16)). In 1991, we
issued the Policy on Applying the
Definition of Species Under the
Endangered Species Act to Pacific
Salmon (ESU Policy; 56 FR 58612;
November 20, 1991), which explains
that a Pacific salmon population will be
considered a DPS, and hence a
‘‘species’’ under the ESA, if it represents
an ‘‘evolutionarily significant unit’’ of
the biological species. The two criteria
for delineating an ESU are: (1) It is
substantially reproductively isolated
from other conspecific populations, and
(2) it represents an important
component in the evolutionary legacy of
the species. The ESU Policy was used to
define the UKTR Chinook salmon ESU
in 1998 (63 FR 11482; March 9, 1998),
and we use it exclusively for defining
distinct population segments of Pacific
salmon. A joint NMFS–U.S. Fish and
Wildlife Service (USFWS) (jointly, ‘‘the
Services’’) policy clarifies the Services’
interpretation of the phrase ‘‘distinct
population segment’’ for the purposes of
listing, delisting, and reclassifying a
species under the ESA (DPS Policy; 61
FR 4722; February 7, 1996). In
announcing this policy, the Services
indicated that the ESU Policy for Pacific
salmon was consistent with the DPS
Policy and that NMFS would continue
to use the ESU Policy for Pacific
salmon.
A species, subspecies, DPS, or ESU is
‘‘endangered’’ if it is in danger of
extinction throughout all or a significant
portion of its range, and ‘‘threatened’’ if
it is likely to become endangered within
the foreseeable future throughout all or
a significant portion of its range (ESA
sections 3(6) and 3(20), respectively, 16
U.S.C. 1532(6) and (20)). Pursuant to the

daltland on DSKBBV9HB2PROD with PROPOSALS
8412
Federal Register / Vol. 83, No. 39 / Tuesday, February 27, 2018 / Proposed Rules
ESA and our implementing regulations,
we determine whether species are
threatened or endangered based on any
one or a combination of the following
five ESA section 4(a)(1) factors: The
present or threatened destruction,
modification, or curtailment of habitat
or range; overutilization for commercial,
recreational, scientific, or educational
purposes; disease or predation;
inadequacy of existing regulatory
mechanisms to address identified
threats; or any other natural or
manmade factors affecting the species’
existence (16 U.S.C. 1533(a)(1), 50 CFR
424.11(c)).
ESA-implementing regulations issued
jointly by NMFS and USFWS (50 CFR
424.14(h)(1)(i)) define substantial
scientific or commercial information in
the context of reviewing a petition to
list, delist, or reclassify a species as
credible scientific or commercial
information in support of the petition’s
claims such that a reasonable person
conducting an impartial scientific
review would conclude that the action
proposed in the petition may be
warranted. Conclusions drawn in the
petition without the support of credible
scientific or commercial information
will not be considered ‘‘substantial
information.’’ In reaching the initial (90day) finding on the petition, we will
consider the information described in
sections 50 CFR 424.14(c), (d), and (g)
(if applicable).
Our determination as to whether the
petition provides substantial scientific
or commercial information indicating
that the petitioned action may be
warranted will depend in part on the
degree to which the petition includes
the following types of information: (1)
Information on current population
status and trends and estimates of
current population sizes and
distributions, both in captivity and the
wild, if available; (2) identification of
the factors under section 4(a)(1) of the
ESA that may affect the species and
where these factors are acting upon the
species; (3) whether and to what extent
any or all of the factors alone or in
combination identified in section 4(a)(1)
of the ESA may cause the species to be
an endangered species or threatened
species (i.e., the species is currently in
danger of extinction or is likely to
become so within the foreseeable
future), and, if so, how high in
magnitude and how imminent the
threats to the species and its habitat are;
(4) information on adequacy of
regulatory protections and effectiveness
of conservation activities by States as
well as other parties, that have been
initiated or that are ongoing, that may
protect the species or its habitat; and (5)
VerDate Sep<11>2014

Jkt 244001
a complete, balanced representation of
the relevant facts, including information
that may contradict claims in the
petition. See 50 CFR 424.14(d).
If the petitioner provides
supplemental information before the
initial finding is made and states that it
is part of the petition, the new
information, along with the previously
submitted information, is treated as a
new petition that supersedes the
original petition, and the statutory
timeframes will begin when such
supplemental information is received.
See 50 CFR 424.14(g).
We may also consider information
readily available at the time the
determination is made. We are not
required to consider any supporting
materials cited by the petitioner if the
petitioner does not provide electronic or
hard copies, to the extent permitted by
U.S. copyright law, or appropriate
excerpts or quotations from those
materials (e.g., publications, maps,
reports, letters from authorities). See 50
CFR 424.14(c)(6).
The ‘‘substantial scientific or
commercial information’’ standard must
be applied in light of any prior reviews
or findings we have made on the listing
status of the species that is the subject
of the petition. Where we have already
conducted a finding on, or review of,
the listing status of that species
(whether in response to a petition or on
our own initiative), we will evaluate any
petition received thereafter seeking to
list, delist, or reclassify that species to
determine whether a reasonable person
conducting an impartial scientific
review would conclude that the action
proposed in the petition may be
warranted despite the previous review
or finding. Where the prior review
resulted in a final agency action—such
as a final listing determination, 90-day
not-substantial finding, or 12-month
not-warranted finding—a petitioned
action will generally not be considered
to present substantial scientific and
commercial information indicating that
the action may be warranted unless the
petition provides new information or
analyses not previously considered.
At the 90-day finding stage, we do not
conduct additional research, and we do
not solicit information from parties
outside the agency to help us in
evaluating the petition. We will accept
the petitioners’ sources and
characterizations of the information
presented if they appear to be based on
accepted scientific principles, unless we
have specific information in our files
that indicates the petition’s information
is incorrect, unreliable, obsolete, or
otherwise irrelevant to the requested
action. Information that is susceptible to
PO 00000
Frm 00022
Fmt 4702
Sfmt 4702
more than one interpretation or that is
contradicted by other available
information will not be dismissed at the
90-day finding stage, so long as it is
reliable and a reasonable person
conducting an impartial scientific
review would conclude it supports the
petitioners’ assertions. In other words,
conclusive information indicating the
species may meet the ESA’s
requirements for listing is not required
to make a positive 90-day finding. We
will not conclude that a lack of specific
information alone necessitates a
negative 90-day finding if a reasonable
person conducting an impartial
scientific review would conclude that
the unknown information itself suggests
the species may be at risk of extinction
presently or within the foreseeable
future.
To make a 90-day finding on a
petition to list a species, we evaluate
whether the petition presents
substantial scientific or commercial
information indicating the subject
species may be either threatened or
endangered, as defined by the ESA.
First, we evaluate whether the
information presented in the petition, in
light of the information readily available
in our files, indicates that the petitioned
entity constitutes a ‘‘species’’ eligible for
listing under the ESA. Next, we evaluate
whether the information indicates that
the species faces an extinction risk such
that listing, delisting, or reclassification
may be warranted; this may be indicated
in information expressly discussing the
species’ status and trends, or in
information describing impacts and
threats to the species. We evaluate any
information on specific demographic
factors pertinent to evaluating
extinction risk for the species (e.g.,
population abundance and trends,
productivity, spatial structure, age
structure, sex ratio, diversity, current
and historical range, habitat integrity or
fragmentation), and the potential
contribution of identified demographic
risks to extinction risk for the species.
We then evaluate the potential links
between these demographic risks and
the causative impacts and threats
identified in section 4(a)(1) of the ESA.
Information presented on impacts or
threats should be specific to the species
and should reasonably suggest that one
or more of these factors may be
operative threats that act or have acted
on the species to the point that it may
warrant protection under the ESA.
Broad statements about generalized
threats to the species, or identification
of factors that could negatively impact
a species, do not constitute substantial
information indicating that listing may
be warranted. We look for information
E:\FR\FM\27FEP1.SGM
27FEP1
Federal Register / Vol. 83, No. 39 / Tuesday, February 27, 2018 / Proposed Rules
indicating that not only is the particular
species exposed to a factor, but that the
species may be responding in a negative
fashion; then we assess the potential
significance of that negative response.

UKTR Chinook Salmon ESU
We completed the first status review
for UKTR Basin Chinook salmon in
1998 (Myers et al., 1998). Myers et al.
(1998) defined the UKTR Chinook
salmon ESU as including all spring-run
and fall-run populations from the
Trinity River and Klamath River
upstream from the confluence of the
Trinity River. Based on the information
in the status review, we determined that
the UKTR Chinook salmon ESU was not
at a significant risk of extinction, nor
was it likely to become endangered in
the foreseeable future, and therefore did
not warrant listing under the ESA (63
FR 11482; March 9, 1998). On January
28, 2011, the Secretary of Commerce
received a petition from the Center for
Biological Diversity (CBD), Oregon
Wild, Environmental Protection
Information Center, and The Larch
Company, to list UKTR Chinook salmon
under the ESA and designate critical
habitat. We made a positive 90-day
finding, conducted a status review, and
made a 12-month not warranted finding
on the petitioned actions (77 FR 19597;
April 2, 2012). In reaching our not
warranted conclusion, we confirmed
our earlier finding that spring-run and
fall-run Chinook salmon in the UKTR
Basin constitute a single ESU and,
consistent with our earlier finding,
concluded that the overall extinction
risk of the ESU was considered to be
low over the subsequent 100 years.
Evaluation of Petition and Information
Readily Available in NMFS Files
The petition contains information and
arguments in support of listing Chinook
salmon under the two alternatives
requested by the Petitioners. Under the
first listing alternative, the Petitioners
request that we list as threatened or
endangered the UKTR Chinook salmon
ESU, in contrast to our previous finding
in 2012 that listing this ESU was not
warranted (77 FR 19597; April 2, 2012).
In support of their request, the
Petitioners present information about
recent trends in abundance of the
spring-run component of the UKTR
Chinook salmon ESU, arguing that those
trends indicate that the ESU should be
listed. The Petitioners state that the total
number of naturally spawning springrun Chinook salmon since 1990 has
averaged 9,983 spawners (range: 2,133
to 35,827); however, in recent years, the
abundance of spring-run Chinook has
declined. In fact, three out of the six
VerDate Sep<11>2014
19:03 Feb 26, 2018
Jkt 244001
worst years on record were in the past
decade, with 4,215 spawners in 2014,
2,638 in 2015, and 2,133 in 2016. The
Petitioners note that 2017 was likely to
be even lower and that this trend places
the ESU at risk of extinction. In our
previous not warranted finding (77 FR
19597; April 2, 2012) we found that
recent abundance estimates were low
relative to historical abundance
estimates and that this was most evident
in two of the three spring-run
populations units evaluated.
Specifically, the Biological Review
Team (BRT) that was asked to review
the status of the UKTR Chinook salmon
in 2011 noted concerns about the low
numbers of spawners within the springrun populations and while they
concluded that these low numbers did
not pose an immediate risk of extinction
to the ESU, they were concerned that
appropriate habitat and conditions that
allow for the expression of the springrun life history were limited (Williams
et al. 2011). Given the new information
presented by the Petitioners, which
show a continued decline in spring-run
spawners since the 2011 review, we find
that a reasonable person would
conclude that low spawner abundance
may be impacting overall genetic
diversity of the ESU to the point where
the petitioned action may be warranted,
and that further evaluation is necessary.
The Petitioners also present
information on the threats facing the
spring-run component of the UKTR
Chinook salmon ESU. The Petitioners
argue that all five ESA section 4(a)(1)
factors contribute to the need to list the
species. However, we find that they
have only provided support for two of
the factors: Disease and the inadequacy
of existing regulatory mechanisms. The
Petitioners claim that recent
observations indicate high rates of
disease in juvenile Chinook salmon. In
2014, 81 percent of juvenile Chinook
salmon sampled were infected with the
lethal parasite Ceratonova shasta. In
2015, this percentage rose to 90 percent
of sampled juvenile Chinook salmon.
These high rates of infection were
purportedly the result of poor water
quality, low flows, and prolonged
absence of flushing flows necessary to
scour the river bed (Hillemeier et al.
2017). While we do not have additional
information in our files on disease risks
to Chinook salmon, we consider
infection from C. shasta to pose a
significant risk to coho salmon in the
Klamath River basin (NMFS 2013). In
the latest 5-year review of the
threatened Southern Oregon/Northern
California Coast Coho Salmon ESU, we
found that severe infection of juvenile
PO 00000
Frm 00023
Fmt 4702

8413
coho salmon by C. shasta may
contribute to declining adult coho
salmon returns in the Klamath basin.
Risk of mortality from infection
(referred to as ceratomyxosis) was
greatest at higher temperatures, and
given the drought conditions that have
persisted for the last four years and
associated high water temperatures, we
concluded that the risk from
ceratomyxosis has likely been higher in
the last five years than in the previous
five years (NMFS 2016). Based on the
information from the Petitioners,
infection and associated mortality from
ceratomyxosis may also be a significant
threat to Chinook salmon in the
Klamath, particularly given these two
species’ similar life histories.
Considering the information indicating
a declining abundance of spring-run
spawners, we find that a reasonable
person would conclude that additional
mortality of UKTR chinook salmon from
disease indicates that the petitioned
action may be warranted.
The Petitioners also claim that current
hatchery practices and harvest
management are inadequate, with
current exploitation rates of the species
leading to the observed decline in the
ESU. In support of their argument, the
petitioners claim that the majority of the
naturally spawning Chinook salmon in
the Trinity basin are of hatchery origin.
The Petitioners state that the high
proportion of hatchery fish further
supports their argument about the low
number of returning spring-run Chinook
salmon. The Petitioners also provide
information on the inadequacy of
harvest management. The Petitioners
describe how fisheries managers have
expressed the need to manage springrun Chinook salmon. In 2003, the
Klamath Fisheries Management Council
reported to the Pacific Fisheries
Management Council that they intended
to develop management
recommendations aimed at the
conservation of spring-run Chinook
salmon while preserving meaningful
harvest opportunities for both ocean and
river fisheries. The Petitioners claim
that harvest management objectives
were never set. We also do not have any
information in our files to show that
current regulatory mechanisms
adequately address the threats identified
above for spring-run Chinook salmon.
Therefore, we find that a reasonable
person would conclude that the
inadequacy of existing regulatory
measures to address threats of
overutilization or disease of the UKTR
Chinook salmon ESU indicate that the
petitioned action may be warranted.
Under the second recommended
listing alternative, the Petitioners

daltland on DSKBBV9HB2PROD with PROPOSALS
present new genetic evidence to suggest
the spring-run Chinook salmon
populations in the UKTR Basin may
qualify as a separate ESU from the fallrun populations and request this new
ESU to be listed based on the threats
identified above. Based on biological,
genetic, and ecological information
compiled and reviewed as part of the
status review for Chinook salmon
(Myers et al., 1998), we included all
spring-run and fall-run Chinook salmon
populations in the Klamath River Basin
upstream from the confluence of the
Klamath and Trinity rivers in the UKTR
Chinook salmon ESU (63 FR 11482;
March 9, 1998). In our 2012 not
warranted decision (77 FR 19597; April
2, 2012), we reconfirmed the
configuration of the UKTR Chinook
salmon ESU. In both cases, we found
that spring-run and fall-run Chinook
salmon populations in the UKTR Basin
were genetically very similar and not
reproductively isolated from each other.
The Petitioners contend the findings
from a recently published article on the
evolutionary basis of premature
migration in Pacific salmon (Prince et
al. 2017) indicate that spring-run
Chinook salmon in the UKTR Basin
should be considered a separate ESU,
and therefore eligible to be listed as
threatened or endangered. Prince et al.
(2017) suggest that their results indicate
that premature migration (e.g. springrun Chinook salmon) arose from a single
evolutionary event within the species
and, if lost, are not likely to re-evolve
in time frames relevant to conservation
planning. Therefore, the Petitioners
contend that the new genetic
information indicates that spring-run
Chinook salmon in the UKTR Basin
satisfy the criteria for a species to be
considered an ESU because: (1) They are
substantially reproductively isolated,
and (2) they represent an important
component in the evolutionary legacy of
the species. We have reviewed the new
genetic information and find that a
reasonable person may conclude that
spring-run Chinook salmon in the UKTR
Basin would qualify as an ESU pursuant
to our ESU Policy.
Petition Finding
After reviewing the information
contained in the petition, as well as
information readily available in our
files, we conclude the petition presents
substantial scientific information
indicating the petitioned actions to list
as threatened or endangered the UKTR
Chinook salmon ESU or, alternatively,
to create a new ESU to describe springrun Chinook salmon in the UKTR Basin
and list the new ESU as threatened or
endangered may be warranted.

Therefore, in accordance with section
4(b)(3)(A) of the ESA and NMFS’
implementing regulations (50 CFR
424.14(h)(2)), we will commence a
status review of the UKTR Chinook
salmon ESU. During our status review,
we will first consider the request to
designate a new ESU to describe springrun Chinook salmon in the UKTR Basin
in light of our ESU Policy (56 FR 58612;
November 20, 1991). If we determine
that the spring-run component qualifies
as a separate ESU, then we will evaluate
its status to determine whether it is in
danger of extinction or likely to become
so within the foreseeable future
throughout all or a significant portion of
its range. Otherwise, we will evaluate
the status of the existing UKTR Chinook
salmon ESU to determine if it warrants
listing. As required by section 4(b)(3)(B)
of the ESA, we will publish a finding as
to whether listing an ESU as endangered
or threatened is warranted.
information concerning the impacts of
environmental variability and climate
change on survival, recruitment,
distribution, and/or extinction risk.
We are also requesting information on
areas that may qualify as critical habitat
for Chinook salmon in the UKTR Basin.
Please identify: Physical and biological
features essential to the conservation of
the species that may require special
management considerations; areas
occupied by the species containing
those physical and biological features;
and unoccupied areas essential for
conservation of the species (16 U.S.C.
1533(a)(3)(A); 50 CFR 424.12).
We request that all information be
accompanied by: (1) Supporting
documentation such as maps,
bibliographic references, or reprints of
pertinent publications; and (2) the
submitter’s name, address, and any
association, institution, or business that
the person represents.
Information Solicited
To ensure that our status review is
informed by the best available scientific
and commercial information, we are
opening a 60-day public comment
period to solicit information on Chinook
salmon in the UKTR Basin. We also
solicited information on Chinook
salmon in the UKTR Basin with our 90day finding on the previous petition (76
FR 20302; April 12, 2011). Therefore,
please do not re-submit information
submitted in response to that previous
finding. We request information from
the public, concerned governmental
agencies, Native American tribes, the
scientific community, agricultural and
forestry groups, conservation groups,
fishing groups, industry, or any other
interested parties concerning the current
and/or historical status of Chinook
salmon in the UKTR Basin. Specifically,
we request information regarding: (1)
Species abundance; (2) species
productivity; (3) species distribution or
population spatial structure; (4) patterns
of phenotypic, genotypic, and life
history diversity; (5) habitat conditions
and associated limiting factors and
threats; (6) ongoing or planned efforts to
protect and restore the species and their
habitats; (7) information on the
adequacy of existing regulatory
mechanisms, whether protections are
being implemented, and whether they
are proving effective in conserving the
species; (8) data concerning the status
and trends of identified limiting factors
or threats; (9) information on targeted
harvest (commercial and recreational)
and bycatch of the species; (10) other
new information, data, or corrections
including, but not limited to, taxonomic
or nomenclatural changes; and (11)

SUPPLEMENTARY INFORMATION:
Background
On November 2, 2017, the Secretary of Commerce received a petition
from the Karuk Tribe and Salmon River Restoration Council (hereafter,
the Petitioners) to list as threatened or endangered the UKTR Chinook
salmon ESU or, alternatively, create and list a new ESU to describe
Klamath Spring Chinook salmon. In their petition, the Petitioners used
various phrases as well as ``Klamath Spring Chinook'' to describe the
area in which they are requesting that we create a new ESU for spring-
run Chinook salmon. Because their request is generally made in
reference to the spring-run Chinook salmon component of the UKTR ESU of
Chinook salmon, we will use the description of the currently defined
ESU to describe the area in which the Petitioners are requesting that
we create a new spring-run Chinook salmon ESU. We will hereinafter
refer to that area as the UKTR Basin. We described all Klamath River
Basin populations of Chinook salmon from the Trinity River and Klamath
River upstream from the confluence of the Trinity River as the UKTR
ESU, which includes both spring-run and fall-run fish (63 FR 11482;
March 9, 1998). The Petitioners also request designation of critical
habitat concurrently with the listing. Copies of the petition are
available as described above (see FOR FURTHER INFORMATION CONTACT).
ESA Statutory, Regulatory, Policy Provisions, and Evaluation Framework
Section 4(b)(3)(A) of the ESA of 1973, as amended (16 U.S.C. 1531
et seq.), requires, to the maximum extent practicable, that within 90
days of receipt of a petition to list a species as threatened or
endangered, the Secretary of Commerce make a finding on whether that
petition presents substantial scientific or commercial information
indicating that the petitioned action may be warranted, and to promptly
publish such finding in the Federal Register (16 U.S.C. 1533(b)(3)(A)).
When it is found that substantial scientific or commercial information
in a petition indicates the petitioned action may be warranted (a
``positive 90-day finding''), we are required to promptly commence a
review of the status of the species concerned during which we will
conduct a comprehensive review of the best available scientific and
commercial information. In such cases, we conclude the review with a
finding as to whether, in fact, the petitioned action is warranted
within 12 months of receipt of the petition. Because the finding at the
12-month stage is based on a more thorough review of the available
information, as compared to the narrow scope of review at the 90-day
stage, a ``may be warranted'' finding does not prejudge the outcome of
the status review.
Under the ESA, a listing determination may address a species, which
is defined to also include subspecies and, for any vertebrate species,
any distinct population segment (DPS) that interbreeds when mature (16
U.S.C. 1532(16)). In 1991, we issued the Policy on Applying the
Definition of Species Under the Endangered Species Act to Pacific
Salmon (ESU Policy; 56 FR 58612; November 20, 1991), which explains
that a Pacific salmon population will be considered a DPS, and hence a
``species'' under the ESA, if it represents an ``evolutionarily
significant unit'' of the biological species. The two criteria for
delineating an ESU are: (1) It is substantially reproductively isolated
from other conspecific populations, and (2) it represents an important
component in the evolutionary legacy of the species. The ESU Policy was
used to define the UKTR Chinook salmon ESU in 1998 (63 FR 11482; March
9, 1998), and we use it exclusively for defining distinct population
segments of Pacific salmon. A joint NMFS-U.S. Fish and Wildlife Service
(USFWS) (jointly, ``the Services'') policy clarifies the Services'
interpretation of the phrase ``distinct population segment'' for the
purposes of listing, delisting, and reclassifying a species under the
ESA (DPS Policy; 61 FR 4722; February 7, 1996). In announcing this
policy, the Services indicated that the ESU Policy for Pacific salmon
was consistent with the DPS Policy and that NMFS would continue to use
the ESU Policy for Pacific salmon.
A species, subspecies, DPS, or ESU is ``endangered'' if it is in
danger of extinction throughout all or a significant portion of its
range, and ``threatened'' if it is likely to become endangered within
the foreseeable future throughout all or a significant portion of its
range (ESA sections 3(6) and 3(20), respectively, 16 U.S.C. 1532(6) and
(20)). Pursuant to the
[[Page 8412]]
ESA and our implementing regulations, we determine whether species are
threatened or endangered based on any one or a combination of the
following five ESA section 4(a)(1) factors: The present or threatened
destruction, modification, or curtailment of habitat or range;
overutilization for commercial, recreational, scientific, or
educational purposes; disease or predation; inadequacy of existing
regulatory mechanisms to address identified threats; or any other
natural or manmade factors affecting the species' existence (16 U.S.C.
1533(a)(1), 50 CFR 424.11(c)).
ESA-implementing regulations issued jointly by NMFS and USFWS (50
CFR 424.14(h)(1)(i)) define substantial scientific or commercial
information in the context of reviewing a petition to list, delist, or
reclassify a species as credible scientific or commercial information
in support of the petition's claims such that a reasonable person
conducting an impartial scientific review would conclude that the
action proposed in the petition may be warranted. Conclusions drawn in
the petition without the support of credible scientific or commercial
information will not be considered ``substantial information.'' In
reaching the initial (90-day) finding on the petition, we will consider
the information described in sections 50 CFR 424.14(c), (d), and (g)
(if applicable).
Our determination as to whether the petition provides substantial
scientific or commercial information indicating that the petitioned
action may be warranted will depend in part on the degree to which the
petition includes the following types of information: (1) Information
on current population status and trends and estimates of current
population sizes and distributions, both in captivity and the wild, if
available; (2) identification of the factors under section 4(a)(1) of
the ESA that may affect the species and where these factors are acting
upon the species; (3) whether and to what extent any or all of the
factors alone or in combination identified in section 4(a)(1) of the
ESA may cause the species to be an endangered species or threatened
species (i.e., the species is currently in danger of extinction or is
likely to become so within the foreseeable future), and, if so, how
high in magnitude and how imminent the threats to the species and its
habitat are; (4) information on adequacy of regulatory protections and
effectiveness of conservation activities by States as well as other
parties, that have been initiated or that are ongoing, that may protect
the species or its habitat; and (5) a complete, balanced representation
of the relevant facts, including information that may contradict claims
in the petition. See 50 CFR 424.14(d).
If the petitioner provides supplemental information before the
initial finding is made and states that it is part of the petition, the
new information, along with the previously submitted information, is
treated as a new petition that supersedes the original petition, and
the statutory timeframes will begin when such supplemental information
is received. See 50 CFR 424.14(g).
We may also consider information readily available at the time the
determination is made. We are not required to consider any supporting
materials cited by the petitioner if the petitioner does not provide
electronic or hard copies, to the extent permitted by U.S. copyright
law, or appropriate excerpts or quotations from those materials (e.g.,
publications, maps, reports, letters from authorities). See 50 CFR
424.14(c)(6).
The ``substantial scientific or commercial information'' standard
must be applied in light of any prior reviews or findings we have made
on the listing status of the species that is the subject of the
petition. Where we have already conducted a finding on, or review of,
the listing status of that species (whether in response to a petition
or on our own initiative), we will evaluate any petition received
thereafter seeking to list, delist, or reclassify that species to
determine whether a reasonable person conducting an impartial
scientific review would conclude that the action proposed in the
petition may be warranted despite the previous review or finding. Where
the prior review resulted in a final agency action--such as a final
listing determination, 90-day not-substantial finding, or 12-month not-
warranted finding--a petitioned action will generally not be considered
to present substantial scientific and commercial information indicating
that the action may be warranted unless the petition provides new
information or analyses not previously considered.
At the 90-day finding stage, we do not conduct additional research,
and we do not solicit information from parties outside the agency to
help us in evaluating the petition. We will accept the petitioners'
sources and characterizations of the information presented if they
appear to be based on accepted scientific principles, unless we have
specific information in our files that indicates the petition's
information is incorrect, unreliable, obsolete, or otherwise irrelevant
to the requested action. Information that is susceptible to more than
one interpretation or that is contradicted by other available
information will not be dismissed at the 90-day finding stage, so long
as it is reliable and a reasonable person conducting an impartial
scientific review would conclude it supports the petitioners'
assertions. In other words, conclusive information indicating the
species may meet the ESA's requirements for listing is not required to
make a positive 90-day finding. We will not conclude that a lack of
specific information alone necessitates a negative 90-day finding if a
reasonable person conducting an impartial scientific review would
conclude that the unknown information itself suggests the species may
be at risk of extinction presently or within the foreseeable future.
To make a 90-day finding on a petition to list a species, we
evaluate whether the petition presents substantial scientific or
commercial information indicating the subject species may be either
threatened or endangered, as defined by the ESA. First, we evaluate
whether the information presented in the petition, in light of the
information readily available in our files, indicates that the
petitioned entity constitutes a ``species'' eligible for listing under
the ESA. Next, we evaluate whether the information indicates that the
species faces an extinction risk such that listing, delisting, or
reclassification may be warranted; this may be indicated in information
expressly discussing the species' status and trends, or in information
describing impacts and threats to the species. We evaluate any
information on specific demographic factors pertinent to evaluating
extinction risk for the species (e.g., population abundance and trends,
productivity, spatial structure, age structure, sex ratio, diversity,
current and historical range, habitat integrity or fragmentation), and
the potential contribution of identified demographic risks to
extinction risk for the species. We then evaluate the potential links
between these demographic risks and the causative impacts and threats
identified in section 4(a)(1) of the ESA.
Information presented on impacts or threats should be specific to
the species and should reasonably suggest that one or more of these
factors may be operative threats that act or have acted on the species
to the point that it may warrant protection under the ESA. Broad
statements about generalized threats to the species, or identification
of factors that could negatively impact a species, do not constitute
substantial information indicating that listing may be warranted. We
look for information
[[Page 8413]]
indicating that not only is the particular species exposed to a factor,
but that the species may be responding in a negative fashion; then we
assess the potential significance of that negative response.
UKTR Chinook Salmon ESU
We completed the first status review for UKTR Basin Chinook salmon
in 1998 (Myers et al., 1998). Myers et al. (1998) defined the UKTR
Chinook salmon ESU as including all spring-run and fall-run populations
from the Trinity River and Klamath River upstream from the confluence
of the Trinity River. Based on the information in the status review, we
determined that the UKTR Chinook salmon ESU was not at a significant
risk of extinction, nor was it likely to become endangered in the
foreseeable future, and therefore did not warrant listing under the ESA
(63 FR 11482; March 9, 1998). On January 28, 2011, the Secretary of
Commerce received a petition from the Center for Biological Diversity
(CBD), Oregon Wild, Environmental Protection Information Center, and
The Larch Company, to list UKTR Chinook salmon under the ESA and
designate critical habitat. We made a positive 90-day finding,
conducted a status review, and made a 12-month not warranted finding on
the petitioned actions (77 FR 19597; April 2, 2012). In reaching our
not warranted conclusion, we confirmed our earlier finding that spring-
run and fall-run Chinook salmon in the UKTR Basin constitute a single
ESU and, consistent with our earlier finding, concluded that the
overall extinction risk of the ESU was considered to be low over the
subsequent 100 years.
Evaluation of Petition and Information Readily Available in NMFS Files
The petition contains information and arguments in support of
listing Chinook salmon under the two alternatives requested by the
Petitioners. Under the first listing alternative, the Petitioners
request that we list as threatened or endangered the UKTR Chinook
salmon ESU, in contrast to our previous finding in 2012 that listing
this ESU was not warranted (77 FR 19597; April 2, 2012). In support of
their request, the Petitioners present information about recent trends
in abundance of the spring-run component of the UKTR Chinook salmon
ESU, arguing that those trends indicate that the ESU should be listed.
The Petitioners state that the total number of naturally spawning
spring-run Chinook salmon since 1990 has averaged 9,983 spawners
(range: 2,133 to 35,827); however, in recent years, the abundance of
spring-run Chinook has declined. In fact, three out of the six worst
years on record were in the past decade, with 4,215 spawners in 2014,
2,638 in 2015, and 2,133 in 2016. The Petitioners note that 2017 was
likely to be even lower and that this trend places the ESU at risk of
extinction. In our previous not warranted finding (77 FR 19597; April
2, 2012) we found that recent abundance estimates were low relative to
historical abundance estimates and that this was most evident in two of
the three spring-run populations units evaluated. Specifically, the
Biological Review Team (BRT) that was asked to review the status of the
UKTR Chinook salmon in 2011 noted concerns about the low numbers of
spawners within the spring-run populations and while they concluded
that these low numbers did not pose an immediate risk of extinction to
the ESU, they were concerned that appropriate habitat and conditions
that allow for the expression of the spring-run life history were
limited (Williams et al. 2011). Given the new information presented by
the Petitioners, which show a continued decline in spring-run spawners
since the 2011 review, we find that a reasonable person would conclude
that low spawner abundance may be impacting overall genetic diversity
of the ESU to the point where the petitioned action may be warranted,
and that further evaluation is necessary.
The Petitioners also present information on the threats facing the
spring-run component of the UKTR Chinook salmon ESU. The Petitioners
argue that all five ESA section 4(a)(1) factors contribute to the need
to list the species. However, we find that they have only provided
support for two of the factors: Disease and the inadequacy of existing
regulatory mechanisms. The Petitioners claim that recent observations
indicate high rates of disease in juvenile Chinook salmon. In 2014, 81
percent of juvenile Chinook salmon sampled were infected with the
lethal parasite Ceratonova shasta. In 2015, this percentage rose to 90
percent of sampled juvenile Chinook salmon. These high rates of
infection were purportedly the result of poor water quality, low flows,
and prolonged absence of flushing flows necessary to scour the river
bed (Hillemeier et al. 2017). While we do not have additional
information in our files on disease risks to Chinook salmon, we
consider infection from C. shasta to pose a significant risk to coho
salmon in the Klamath River basin (NMFS 2013). In the latest 5-year
review of the threatened Southern Oregon/Northern California Coast Coho
Salmon ESU, we found that severe infection of juvenile coho salmon by
C. shasta may contribute to declining adult coho salmon returns in the
Klamath basin. Risk of mortality from infection (referred to as
ceratomyxosis) was greatest at higher temperatures, and given the
drought conditions that have persisted for the last four years and
associated high water temperatures, we concluded that the risk from
ceratomyxosis has likely been higher in the last five years than in the
previous five years (NMFS 2016). Based on the information from the
Petitioners, infection and associated mortality from ceratomyxosis may
also be a significant threat to Chinook salmon in the Klamath,
particularly given these two species' similar life histories.
Considering the information indicating a declining abundance of spring-
run spawners, we find that a reasonable person would conclude that
additional mortality of UKTR chinook salmon from disease indicates that
the petitioned action may be warranted.
The Petitioners also claim that current hatchery practices and
harvest management are inadequate, with current exploitation rates of
the species leading to the observed decline in the ESU. In support of
their argument, the petitioners claim that the majority of the
naturally spawning Chinook salmon in the Trinity basin are of hatchery
origin. The Petitioners state that the high proportion of hatchery fish
further supports their argument about the low number of returning
spring-run Chinook salmon. The Petitioners also provide information on
the inadequacy of harvest management. The Petitioners describe how
fisheries managers have expressed the need to manage spring-run Chinook
salmon. In 2003, the Klamath Fisheries Management Council reported to
the Pacific Fisheries Management Council that they intended to develop
management recommendations aimed at the conservation of spring-run
Chinook salmon while preserving meaningful harvest opportunities for
both ocean and river fisheries. The Petitioners claim that harvest
management objectives were never set. We also do not have any
information in our files to show that current regulatory mechanisms
adequately address the threats identified above for spring-run Chinook
salmon. Therefore, we find that a reasonable person would conclude that
the inadequacy of existing regulatory measures to address threats of
overutilization or disease of the UKTR Chinook salmon ESU indicate that
the petitioned action may be warranted.
Under the second recommended listing alternative, the Petitioners
[[Page 8414]]
present new genetic evidence to suggest the spring-run Chinook salmon
populations in the UKTR Basin may qualify as a separate ESU from the
fall-run populations and request this new ESU to be listed based on the
threats identified above. Based on biological, genetic, and ecological
information compiled and reviewed as part of the status review for
Chinook salmon (Myers et al., 1998), we included all spring-run and
fall-run Chinook salmon populations in the Klamath River Basin upstream
from the confluence of the Klamath and Trinity rivers in the UKTR
Chinook salmon ESU (63 FR 11482; March 9, 1998). In our 2012 not
warranted decision (77 FR 19597; April 2, 2012), we reconfirmed the
configuration of the UKTR Chinook salmon ESU. In both cases, we found
that spring-run and fall-run Chinook salmon populations in the UKTR
Basin were genetically very similar and not reproductively isolated
from each other. The Petitioners contend the findings from a recently
published article on the evolutionary basis of premature migration in
Pacific salmon (Prince et al. 2017) indicate that spring-run Chinook
salmon in the UKTR Basin should be considered a separate ESU, and
therefore eligible to be listed as threatened or endangered. Prince et
al. (2017) suggest that their results indicate that premature migration
(e.g. spring-run Chinook salmon) arose from a single evolutionary event
within the species and, if lost, are not likely to re-evolve in time
frames relevant to conservation planning. Therefore, the Petitioners
contend that the new genetic information indicates that spring-run
Chinook salmon in the UKTR Basin satisfy the criteria for a species to
be considered an ESU because: (1) They are substantially reproductively
isolated, and (2) they represent an important component in the
evolutionary legacy of the species. We have reviewed the new genetic
information and find that a reasonable person may conclude that spring-
run Chinook salmon in the UKTR Basin would qualify as an ESU pursuant
to our ESU Policy.
Petition Finding
After reviewing the information contained in the petition, as well
as information readily available in our files, we conclude the petition
presents substantial scientific information indicating the petitioned
actions to list as threatened or endangered the UKTR Chinook salmon ESU
or, alternatively, to create a new ESU to describe spring-run Chinook
salmon in the UKTR Basin and list the new ESU as threatened or
endangered may be warranted. Therefore, in accordance with section
4(b)(3)(A) of the ESA and NMFS' implementing regulations (50 CFR
424.14(h)(2)), we will commence a status review of the UKTR Chinook
salmon ESU. During our status review, we will first consider the
request to designate a new ESU to describe spring-run Chinook salmon in
the UKTR Basin in light of our ESU Policy (56 FR 58612; November 20,
1991). If we determine that the spring-run component qualifies as a
separate ESU, then we will evaluate its status to determine whether it
is in danger of extinction or likely to become so within the
foreseeable future throughout all or a significant portion of its
range. Otherwise, we will evaluate the status of the existing UKTR
Chinook salmon ESU to determine if it warrants listing. As required by
section 4(b)(3)(B) of the ESA, we will publish a finding as to whether
listing an ESU as endangered or threatened is warranted.
Information Solicited
To ensure that our status review is informed by the best available
scientific and commercial information, we are opening a 60-day public
comment period to solicit information on Chinook salmon in the UKTR
Basin. We also solicited information on Chinook salmon in the UKTR
Basin with our 90-day finding on the previous petition (76 FR 20302;
April 12, 2011). Therefore, please do not re-submit information
submitted in response to that previous finding. We request information
from the public, concerned governmental agencies, Native American
tribes, the scientific community, agricultural and forestry groups,
conservation groups, fishing groups, industry, or any other interested
parties concerning the current and/or historical status of Chinook
salmon in the UKTR Basin. Specifically, we request information
regarding: (1) Species abundance; (2) species productivity; (3) species
distribution or population spatial structure; (4) patterns of
phenotypic, genotypic, and life history diversity; (5) habitat
conditions and associated limiting factors and threats; (6) ongoing or
planned efforts to protect and restore the species and their habitats;
(7) information on the adequacy of existing regulatory mechanisms,
whether protections are being implemented, and whether they are proving
effective in conserving the species; (8) data concerning the status and
trends of identified limiting factors or threats; (9) information on
targeted harvest (commercial and recreational) and bycatch of the
species; (10) other new information, data, or corrections including,
but not limited to, taxonomic or nomenclatural changes; and (11)
information concerning the impacts of environmental variability and
climate change on survival, recruitment, distribution, and/or
extinction risk.
We are also requesting information on areas that may qualify as
critical habitat for Chinook salmon in the UKTR Basin. Please identify:
Physical and biological features essential to the conservation of the
species that may require special management considerations; areas
occupied by the species containing those physical and biological
features; and unoccupied areas essential for conservation of the
species (16 U.S.C. 1533(a)(3)(A); 50 CFR 424.12).
We request that all information be accompanied by: (1) Supporting
documentation such as maps, bibliographic references, or reprints of
pertinent publications; and (2) the submitter's name, address, and any
association, institution, or business that the person represents.
