SUPPLEMENTARY INFORMATION:
Executive Summary
Why we need to publish a rule. Under
the Act, if we determine a plant species
no longer meets the definition of an
endangered or threatened species, we
remove it from the Federal List of
Endangered and Threatened Plants (i.e.,
we ‘‘delist’’ it). Delisting a species can
be completed only by issuing a rule
through the Administrative Procedure
Act rulemaking process.
What this document does. This rule
removes (delists) the golden paintbrush
from the Federal List of Endangered and
Threatened Plants because it no longer
meets the Act’s definition of either a
threatened species or an endangered
species.
The basis for our action. Under the
Act, we may determine that a species is
an endangered or threatened species
because of any of the following 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
PO 00000

Sfmt 4700
existence. The determination to delist a
species must be based on an analysis of
the same factors. Based on an
assessment of the best available
information regarding the status of and
threats to the golden paintbrush, we
have determined that the species no
longer meets the definition of a
threatened species or an endangered
species under the Act.
We have determined that golden
paintbrush is not in danger of extinction
now nor likely to become so in the
foreseeable future based on a
comprehensive review of its status and
listing factors. Specifically, our recent
review indicated: (1) An increase in the
known number of occurrences of the
species within its geographic range, and
increased abundance in many
populations; (2) resiliency of the species
to existing and potential threats; (3) 45
of 48 sites with golden paintbrush are in
either public ownership; are owned by
a conservation-oriented,
nongovernmental organization; or are
under conservation easement; and (4)
the implementation of beneficial
management practices for the species.
Accordingly, the golden paintbrush no
longer meets the definition of a
threatened species or an endangered
species under the Act.
Peer review and public comment. The
purpose of peer review is to ensure that
our determination regarding the status
of the species under the Act is based on
scientifically sound data, assumptions,
and analyses. We prepared a species
biological report (SBR) for golden
paintbrush (Service 2019) and sought
peer review on the report 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 sent the report to four appropriate
and independent specialists with
knowledge of the biology and ecology of
the golden paintbrush and received
three responses. The comments and
recommendations of the peer reviewers
have been incorporated into the SBR as
appropriate, and they informed the
proposed rule. We posted the peer
reviews on https://www.regulations.gov
under Docket No. FWS–R1–ES–2020–
0060. Furthermore, in our June 30, 2021,
proposed rule (86 FR 34695), we
requested that all interested parties
submit written comments on the
proposal by August 30, 2021. We
received 10 public comments in
response to the proposed rule as
discussed below in Summary of
Comments and Recommendations.

Staff at the Washington Fish and
Wildlife Office (WFWO), in consultation
with other species experts, prepared the
SBR for golden paintbrush (Service
2019). The report represents a
compilation of the best scientific and
commercial data available concerning
the status of the species, including the
impacts of past and present factors (both
negative and beneficial) affecting the
species. The report formed the scientific
basis for our 5-year status review and
this final rule. The report is posted on

Previous Federal Actions
On May 10, 1994, we published in the
Federal Register (59 FR 24106) a
proposed rule to list the golden
paintbrush as a threatened species
under the Act (16 U.S.C. 1531 et seq.).
On June 11, 1997, we published in the
Federal Register (62 FR 31740) a final
rule to list the species as a threatened
species under the Act. The final rule
included a determination that the
designation of critical habitat for the
golden paintbrush was not prudent.
In August 2000, we finalized a
recovery plan for the species (Service
2000, entire), which we supplemented
in May 2010 with the final recovery
plan for the prairie species of western
Oregon and southwestern Washington
(Service 2010, entire).
On July 6, 2005, we initiated 5-year
reviews for 33 plant and animal species,
including the golden paintbrush, under
section 4(c)(2) of the Act, and requested
information on the species’ status (see
70 FR 38972). The 5-year status review,
completed in September 2007 (Service
2007, entire), resulted in a
recommendation to maintain the status
of the golden paintbrush as threatened.
The 2007 5-year status review is
available on the Service’s website at
https://ecos.fws.gov/docs/five_year_
review/doc1764.pdf.
On January 22, 2018, we initiated 5year status reviews for 18 plant and
animal species, including the golden
paintbrush, under section 4(c)(2) of the
Act, and requested information on the
species’ status (see 83 FR 3014). In 2019,
we completed our SBR (Service 2019).
On June 30, 2021, we published in the
Federal Register (86 FR 34695) a
proposed rule to remove golden
paintbrush from the List, and we made
available our draft post-delisting
monitoring plan for public review and
comment. Our proposed rule followed
from the recommendation of the most
recent 5-year review for the golden
paintbrush, as well as the data and

analysis contained in the SBR (Service
2019).
Summary of Changes From the
Proposed Rule
In preparing this final rule, we
reviewed and fully considered
comments from the public on the June
30, 2021, proposed rule (86 FR 34695)
and the draft post-delisting monitoring
plan. We updated information presented
in the proposed rule based on comments
and additional information provided as
follows:
(1) We included updated survey
information provided to the Service.
(2) We incorporated additional
information regarding stressors and
potential threats to the species.
(3) We made many small,
nonsubstantive clarifications and
corrections throughout this rule,
including under Summary of Biological
Status and Threats, below, in order to
ensure better consistency, clarify some
information, and update or add new
references.
We considered whether this
additional information altered our
analysis of the magnitude or severity of
threats facing the species. We conclude
that the information we received during
the comment period for the proposed
rule did not change our previous
analysis of the magnitude or severity of
threats facing the species or our
determination that golden paintbrush is
no longer a threatened species and
warrants delisting.
Background
Below, we summarize information for
the golden paintbrush directly relevant
to this final rule. For more information

Species Description and Habitat
Information
The golden paintbrush is native to the
northwestern United States and
southwestern British Columbia. It has
been historically reported from more
than 30 sites from Vancouver Island,
British Columbia, to the Willamette
Valley of Oregon (Hitchcock et al. 1959,
entire; Sheehan and Sprague 1984, p. 5;
PO 00000
Frm 00043
Fmt 4700
Sfmt 4700
46089
Gamon 1995, pp. 5–7). The taxonomy of
the golden paintbrush as a full species
is widely accepted as valid by the
scientific community (Integrated
Taxonomic Information System (ITIS)
2020, entire).
The golden paintbrush is a short-lived
perennial herb formerly included in the
figwort or snapdragon family
(Scrophulariaceae), with current
classification in the Orobanchaceae
family. The genus Castilleja is
hemiparasitic, with roots of
paintbrushes capable of forming
parasitic connections to roots of other
plants; however, paintbrush plants are
probably not host-specific (Mills and
Kummerow 1988, entire) and can grow
successfully, though not as well, even
without a host. Golden paintbrush has
superior performance (survival, height,
number of flowering stems, number of
fruiting stems, number of seed capsules)
where it co-occurs with certain prairie
species, including several perennial
native forbs (e.g., common woolly
sunflower or Oregon sunshine
(Eriophyllum lanatum) and common
yarrow (Achillea millefolium)), as well
as species in other functional groups,
including grasses (e.g., Roemer’s fescue
(Festuca roemeri) and California
oatgrass (Danthonia californica)) and
shrubs (e.g., snowberry
(Symphoricarpos albus)) (Schmidt 2016,
pp. 10–17). Anecdotal observations
suggest that golden paintbrush grows
poorly when associated with annual
grasses (Gamon 1995, p. 17).
Individual golden paintbrush plants
have a median survival of 1 to 5 years,
but some plants can survive for more
than a decade (Service 2019, p. 7).
Plants are up to 30 centimeters (cm) (12
inches (in)) tall and are covered with
soft, somewhat sticky hairs. Stems may
be erect or spreading, in the latter case
giving the appearance of being several
plants, especially when in tall grass.
The lower leaves are broader, with one
to three pairs of short lateral lobes. The
bracts are softly hairy and sticky, golden
yellow, and about the same width as the
upper leaves.
Golden paintbrush plants typically
emerge in early March, with flowering
generally beginning the last week in
April and continuing until early June.
Most plants complete flowering by early
to mid-June, although occasionally
plants flower throughout the summer
and into October. Based on historical
collections and observations, flowering
seems to occur at about the same time
throughout the species’ range.
Individual plants of golden paintbrush
typically need pollinators to set seed.
Bumble bee species (Bombus) appear to
be the most common pollinators visiting

golden paintbrush (Wentworth 1994, p.
5; Kolar and Fessler 2006, in litt.;
Waters 2018, in litt.; Kaye 2019, in litt.),
although sweat bees (Halictidae), miner
bee (Andrena chlorogaster), syrphid fly
(Eristalis hirta), and bee fly (Bombylius
major) have also been observed visiting
golden paintbrush plants (Kolar and
Fessler 2006, in litt.; Waters 2018, in
litt.).
Fruits typically mature from late June
through July, with seed capsules
beginning to open and disperse seed in
August. By mid-July, plants at most sites
are in senescence (the process of
deterioration with age), although this
can vary considerably depending on
available moisture. Capsules persist on
the plants well into the winter, and
often retain seed into the following
spring. Seeds are likely shaken from the
seed capsules by wind, with most
falling a short distance from the parent
plant (Godt et al. 2005, p. 88). The seeds
are light (approximately 8,000 seeds per
gram) and could possibly be dispersed
short distances by wind (Kaye et al.
2012, p. 7). Additionally, there is at
least one reported instance of shortdistance movement of seeds via vole
activity (Kolar and Fessler 2006, in litt.).
Therefore, natural colonization of new
sites would likely occur only over short
distances as plants disperse from
established sites. Germination tests in
different years with seed from various
populations suggest that germination
rates can vary extremely widely both
between sites and between years
(Wentworth 1994, entire). Germination
tests also revealed that seeds likely
remain viable in the wild for several
years (Wentworth 1994, p. 17).
Individuals of the golden paintbrush
require open prairie soils, near-bedrock
soils, or clayey alluvial soils with
suitable host plants. These suitable
habitats occur from zero to 100 meters
(330 feet) above sea level (Service 2000,
p. 5). The golden paintbrush may have
historically grown in deeper soils, but
nearly all of these soils within the
known range of the species have been
converted to agriculture (Lawrence and
Kaye 2006, p. 150; Dunwiddie and
Martin 2016, p. 1). Reintroduction
efforts have targeted sites or microsites,
with features such as mounds or swales
and deeper soils where these efforts
were more likely to be effective
(Dunwiddie and Martin 2016, p. 15).
Populations currently occur on the
mainland in the States of Washington
and Oregon, and on islands in the State
of Washington and in British Columbia,
Canada. Mainland and island
populations form two broad categories
of populations that can vary slightly in
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
habitat setting. Individuals in mainland
populations are found in open,
undulating remnant prairies dominated
by Roemer’s fescue and red fescue
(Festuca rubra) on gravelly or clayey
glacial outwash. Individuals in island
populations are often on the upper
slopes or rims of steep, southwest- or
west-facing, sandy bluffs that are
exposed to salt spray. Individuals in
island populations may also occur on
remnant coastal prairie flats on glacial
deposits of sandy loam. Island prairies
may have historically been dominated
by forbs and foothill sedge (Carex
tumulicola) rather than grasses
(Washington Department of Natural
Resources (WDNR) 2004b, pp. 11, 17);
however, many island sites are now
dominated by red fescue or weedy forbs.
All golden paintbrush sites are subject
to encroachment by woody vegetation if
not managed.
Historically, fire was significant in
maintaining open prairie conditions in
parts of the range of the golden
paintbrush (Boyd 1986, p. 82; Gamon
1995, p. 14; Dunwiddie et al. 2001, p.
162). The golden paintbrush is a poor
competitor, intolerant of shade cast by
encroaching tall nonnatives and litter
duff in fire-suppressed prairies. Native
perennial communities are likely to
support more host species appropriate
for the golden paintbrush than those
dominated by nonnative annuals
(Lawrence and Kaye 2011, p. 173).
Thus, habitats with low presence of
nonnative annuals and high presence of
a diverse assemblage of perennial,
native prairie species are more likely to
provide the best conditions for survival
of golden paintbrush plants year-to-year
(Dunwiddie and Martin 2016, p. 1).
Range, Distribution, Abundance, and
Trends of Golden Paintbrush
The golden paintbrush is endemic to
the Pacific Northwest, historically
occurring from southeastern Vancouver
Island and adjacent islands in British
Columbia, Canada, to the San Juan
Islands and Puget Trough in western
Washington and into the Willamette
Valley of western Oregon (Fertig 2021,
pp. 33–34).
Currently, the species occurs within
British Columbia, Washington, and
Oregon, representing, generally, four
geographic areas (British Columbia,
North Puget Sound, South Puget Sound,
and the Willamette Valley). The species’
historical distribution—before European
settlement and modern development in
the Pacific Northwest—is unknown.
However, the species’ current
distribution is generally representative
PO 00000
Frm 00044
Fmt 4700
Sfmt 4700
of the areas where we suspect the
species occurred historically.
Since its Federal listing in 1997, only
one new population of golden
paintbrush that was likely extant at the
time of listing has been discovered
across the species’ range (Service 2007,
p. 6). All other new populations across
the range are the result of
reintroductions through outplanting or
direct seeding. Seeds used to grow plugs
for outplanting, and plant stock for seed
production, were derived from
populations that were extant at the time
of listing (referred to as ‘‘wild sites’’ in
the SBR and other documents) (Service
2019, p. 5). Please note that in previous
Service documents (Service 2000,
Service 2007, Service 2019), the terms
‘‘site’’ and ‘‘population’’ were used
interchangeably. For the purpose of this
document, we will use ‘‘population’’ to
be more consistent with how the data
have been reported over time (Fertig
2019, pp. 11–38).
At the time of listing (see 62 FR
31740; June 11, 1997), there were 10
known golden paintbrush populations:
8 in Washington and 2 in British
Columbia. No golden paintbrush
populations were known from Oregon at
the time of listing (Sheehan and Sprague
1984, pp. 8–9; WDNR 2004b, p. 2).
Despite its limited geographic range and
isolation of populations, the golden
paintbrush retained exceptionally high
levels of genetic diversity, possibly
because there were several large
populations that remained (Godt et al.
2005, p. 87).
Since its Federal listing, the
distribution and abundance of golden
paintbrush have increased significantly
as a result of outplanting (seeding or
plugging). During the last rangewide
assessment, a minimum of 48
populations were documented (Service
2019, pp. 11–14). Based on these data,
in Washington, there are 19
populations: 5 in the South Puget Sound
prairie landscape, 6 in the San Juan
Islands, 7 on Whidbey Island, and 1
near Dungeness Bay in the Strait of Juan
de Fuca. In Oregon, there are 26 extant
populations within the Willamette
Valley. In British Columbia, there are
three extant populations, each located
on a separate island. Of these 48
populations, only 3 are on private
property (Service 2019, p. 12). The
remaining 45 golden paintbrush
populations are in either public
ownership; are owned by a
conservation-oriented, nongovernmental
organization; or are under conservation
easement.

Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
flowering plants declined to 325,320
(Fertig 2021, p. 22). Although this
appears to be a drop in abundance, we
attribute the rapid increase in
abundance in 2018 to the development
of direct seeding techniques for
establishing new populations, as
opposed to outplanting individual
plants (or plugs) grown in greenhouses.
Most of the populations in Washington
and Oregon’s Willamette Valley were
established by incorporating direct
seeding. The 2018 rangewide
population abundance was not
necessarily reflective of the eventual
long-term population level at a site. A
number of reestablished populations
have been going through a period of
prairie development/progression and
species succession. For example, at
some reestablished populations,
abundance initially increased over
several years then dropped to about 15–
20 percent of the peak abundance
(Fertig 2021, pp. 23–27). Drops in
abundance are somewhat expected as
the populations experience variability
after direct seeding, and we anticipate
that long-term population levels at these
reestablished sites will meet recovery
criteria.
In 2020, there was a reduction of
survey effort due to limitations related
to the COVID pandemic, and while the
majority of populations were surveyed
consistently in Washington, 25
populations in Oregon were not
surveyed. The last 4 years of monitoring
rangewide (2017–2020) represent the 4
years with greatest abundance, even
without data from the 25 sites in Oregon
that were not monitored in 2020 (Fertig
2021, p. 14). The year 2020 also
represents the second highest
abundance of golden paintbrush in the
State of Washington at 202,208
flowering plants, which was a 47.8
percent increase from 136,846 in 2019
(Fertig 2021, p. 11).
In contrast to the newly established
golden paintbrush populations (referred
to as ‘‘outplantings’’), there has been a
steady decline in overall abundance of
the populations extant at the time of
listing since 2012. Abundance at these
populations dropped from just over
15,500 flowering plants in 2012, to
2,223 flowering plants in 2020 (Fertig
2021, p. 11).
The Service considers the
demographics and site conditions of all
golden paintbrush populations across
the species’ range when determining the
status of the species, including
populations extant at the time of listing,
as well as new populations outplanted
since the time of listing. In past Service
documents, the sites with populations
extant at the time of listing have often
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
been referred to as ‘‘wild’’ sites, and
trends of abundance have been tracked
separately from outplanted populations
(see Fertig 2021, p. 14, and Service
2019, p. 30). Because seed from many of
the populations extant at the time of
listing was used to establish populations
across the range, all outplanted
populations have representation from
original source populations, though the
outplanted populations have increased
genetic diversity from their source
populations due to mixed-source
production beds (St. Clair et al. 2020,
p. 590). While declines in abundance
have been occurring steadily in the
populations extant at the time of listing,
we do not believe these sites should be
considered ‘‘wild’’ or different from
outplanted populations, as many have
been managed and/or augmented over
time and many share genetics with the
outplanted populations. Success of
golden paintbrush outplantings has
been associated with microsites with
deeper soils and high richness of native
perennial forbs (Dunwiddie and Martin
2016, p. 1); these microsites were likely
where golden paintbrush persisted
historically, but many of these were
tilled for agricultural purposes or
developed. Many of the golden
paintbrush populations extant at the
time of listing may represent marginal
or less optimal remnant habitats or sites
that were not suitable for other uses
(Dunwiddie et al. 2016, pp. 207–209).
For the purposes of assessing recovery
of the species across its range, the
Service acknowledges that individual
populations will vary in viability, and
these differences between populations
have been accounted for in our current
condition analysis within the SBR
(Service 2019, entire) and in our
evaluation of the species’ overall
resiliency, redundancy, and
representation.
Recovery Criteria
Section 4(f) of the Act directs us to
develop and implement recovery plans
for the conservation and survival of
endangered and threatened species
unless we determine that such a plan
will not promote the conservation of the
species. Under section 4(f)(1)(B)(ii),
recovery plans must, to the maximum
extent practicable, include objective,
measurable criteria which, when met,
would result in a determination, in
accordance with the provisions of
section 4 of the Act, that the species be
removed from the Lists of Endangered
and Threatened Wildlife and Plants.
Recovery plans provide a roadmap for
us and our partners on methods of
enhancing conservation and minimizing
threats to listed species, as well as
PO 00000
Frm 00046
Fmt 4700
Sfmt 4700
measurable criteria against which to
evaluate progress towards recovery and
assess the species’ likely future
condition. However, they are not
regulatory documents and do not
substitute for the determinations and
promulgation of regulations required
under section 4(a)(1) of the Act. A
decision to revise the status of a species,
or to delist a species, is ultimately based
on an analysis of the best scientific and
commercial data available to determine
whether a species is no longer an
endangered species or a threatened
species, regardless of whether that
information differs from the recovery
plan.
There are many paths to
accomplishing recovery of a species,
and recovery may be achieved without
all of the criteria in a recovery plan
being fully met. For example, one or
more criteria may be exceeded while
other criteria may not yet be
accomplished. In that instance, we may
determine that the threats are
minimized sufficiently and that the
species is robust enough that it no
longer meets the Act’s definition of an
endangered species or a threatened
species. In other cases, we may discover
new recovery opportunities after having
finalized the recovery plan. Parties
seeking to conserve the species may use
these opportunities instead of methods
identified in the recovery plan.
Likewise, we may learn new
information about the species after we
finalize the recovery plan. The new
information may change the extent to
which existing criteria are appropriate
for identifying recovery of the species.
The recovery of a species is a dynamic
process requiring adaptive management
that may, or may not, follow all of the
guidance provided in a recovery plan.
Here, we provide a summary of
progress made toward achieving the
recovery criteria for the golden
paintbrush. More detailed information
related to conservation efforts can be
found below under Summary of
Biological Status and Threats. We
completed a final recovery plan for the
golden paintbrush in 2000 (Service
2000, entire), and later supplemented
the plan for part of the species’ range in
2010 (Service 2010, entire). The 2000
plan includes objective, measurable
criteria for delisting; however, the plan
has not been updated for more than 20
years, so some aspects of the plan may
no longer reflect the best scientific
information available for the golden
paintbrush.
Since about 2012, a significant
increase in the number of new
populations has occurred, because of
direct seeding within the species’
E:\FR\FM\19JYR1.SGM
19JYR1
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
ddrumheller on DSK120RN23PROD with RULES1
historical range in Washington and
Oregon, with perhaps the most
significant being the reestablishment of
the golden paintbrush at a number of
sites in Oregon’s Willamette Valley,
where the species was once extirpated.
In addition to improved propagation
techniques, substantial research has
been conducted on the population
biology, fire ecology, and restoration of
the golden paintbrush (Dunwiddie et al.
2001, entire; Gamon 2001, entire; Kaye
and Lawrence 2003, entire; Swenerton
2003, entire; Wayne 2004, entire; WDNR
2004b, entire; Lawrence 2005, entire;
Dunwiddie and Martin 2016, entire;
Lawrence 2015, entire; Schmidt 2016,
entire).
The results of these studies have been
used to guide management of the
species at sites being managed for native
prairie and grassland ecosystems. Active
management to promote the golden
paintbrush is being done to varying
degrees (from targeted to infrequent)
across prairie and grassland sites. An
active seed production program has
been maintained to provide golden
paintbrush seeds and other native
prairie plant seeds to land managers for
population augmentation and
restoration projects across the species’
range in Washington and Oregon.
Additionally, as recommended by the
recovery plan for the golden paintbrush
(Service 2000, p. 31), the State of
Washington prepared a reintroduction
plan for the Service as both internal and
external guidance (WDNR 2004a,
entire).
Below are the delisting criteria
described in the 2000 golden paintbrush
recovery plan (Service 2000, p. 24), as
supplemented in 2010, and the progress
made to date in achieving each
criterion.
Criterion 1 for Delisting
Criterion 1 is that there are at least 20
stable populations distributed
throughout the historical range of the
species. To be deemed stable, a
population must maintain a 5-year
running average population size of at
least 1,000 individuals, where the actual
count never falls below 1,000
individuals in any year. The golden
paintbrush technical team
recommended in the 2007 5-year status
review that this criterion should be
modified. Because it is impractical to
count individual vegetative plants, the
team recommended that the criterion
should be modified to specifically
account for a recovered population as
equal to 1,000 flowering individuals and
known to be stable or increasing as
evidenced by population trends (Service
2007, p. 3). While we did not officially
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
amend or make an addendum to the
recovery plan to incorporate this
recommendation, we accepted this as
the best way to count population
abundance, since monitoring has
consistently counted flowering plants,
following a standardized methodology
set by the Washington Department of
Natural Resources Natural Heritage
Program (WNHP) (Arnett and
Birkhauser 2008, entire; Arnett 2011,
entire).
The Service supplemented this
criterion in its 2010 recovery plan for
the prairie species of western Oregon
and southwestern Washington by
identifying locations for golden
paintbrush reintroductions, specifically
to establish five additional populations
distributed across at least three of the
following recovery zones: Southwest
Washington, Portland, Salem East,
Salem West, Corvallis East, Corvallis
West, Eugene East, and Eugene West.
Priority was given to reestablishing
populations in zones with historical
records of golden paintbrush (Southwest
Washington, Portland, Salem East,
Corvallis East) (Service 2010, p. IV–37).
Progress on Criterion 1
At the time of the proposed rule (data
through 2018), 23 populations averaged
at least 1,000 individuals per year over
the 5-year period, with 8 populations
with a 5-year running average of at least
1,000 individuals. As of 2020, 17
populations averaged at least 1,000
individual plants per year over the 5year period with most recent data from
2016 to 2020 (2015 to 2019 for sites with
no data in 2020). Of these 17
populations, 7 had a 5-year running
average of at least 1,000 individuals,
and an additional 6 populations had a
3-year running average of at least 1,000
individuals (Gray 2022, in litt.). As
noted above, we only count flowering
plants during monitoring, so in most
years a proportion of individual plants
may not be represented in annual
counts because they are not flowering
during surveys. While the most recent
data do not meet the recovery criteria (of
20 such populations), we find that many
of the species’ populations are
sufficiently resilient to make up for the
smaller number of populations based on
the following analysis.
Eight populations currently number
in the tens of thousands of individuals,
the largest totaling 82,692 flowering
plants (Glacial Heritage) (Fertig 2021,
pp. 16–20). Prior to listing, the largest
known population totaled just over
15,000 individuals (Rocky Prairie
Natural Area Preserve) (62 FR 31740;
June 11, 1997). Abundance at these
eight populations is greater
PO 00000
Frm 00047
Fmt 4700
Sfmt 4700
46093
(approximately 10,000 or more
flowering plants) than the 1,000individual threshold established at the
time of the drafting of the recovery plan
for this species (Service 2019, pp. 12–
13). These large populations are
distributed across the species’ range in
both Oregon and Washington,
contributing to the species’ ability to
withstand stochastic or catastrophic
events. Although it is likely that a
number of the more recently established
populations are still experiencing
variability and may experience an initial
peak in abundance followed by a
decline to a lower abundance level,
these larger populations are more likely
to be self-sustaining in the wild over
time, are more able to withstand
stochastic disturbance, have higher
viability, and face an overall lower risk
of extirpation than populations at or just
above the threshold of 1,000
individuals.
In addition, there are now a minimum
of 26 golden paintbrush populations in
western Oregon’s Willamette Valley,
and these populations are distributed
across 4 (Corvallis West, Salem West,
Portland, Eugene West) of the recovery
zones (Kaye 2019, pp. 11–23) identified
in the 2010 supplement to the species’
recovery plan (Service 2010, pp. IV–4,
IV–37). In summary, we conclude that
significant progress has been made
toward achieving this criterion, and for
some populations, the progress is well
beyond numerical levels that were
anticipated at the time of recovery
criteria development. Although we
acknowledge annual variability of
abundance across sites, at least eight
sites across Washington and Oregon
number in the tens of thousands of
individuals (Fertig 2021, pp. 16–20),
which significantly surpasses the
minimum 1,000-individual threshold.
This number of individuals increases
our confidence that the overall viability
of the species is secured, despite having
fewer than 20 populations with a 5-year
running average of at least 1,000
individuals. In addition, new
populations can now be more quickly
established through direct seeding and
there are multiple sites where the
species has recently been seeded. There
are also plans to add new outplantings
into the future (Fertig 2021, p. 11).
Criterion 2 for Delisting
Criterion 2 is that at least 15
populations over 1,000 individuals are
located on protected sites. In order for
a site to be deemed protected, it must be
either owned or managed by a
government agency or private
conservation organization that identifies
maintenance of the species as the
E:\FR\FM\19JYR1.SGM
19JYR1
46094
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
primary management objective for the
site, or the site must be protected by a
permanent conservation easement or
covenant that commits present and
future landowners to the conservation of
the species.
ddrumheller on DSK120RN23PROD with RULES1
Progress on Criterion 2
This recovery criterion has not been
met as phrased in the recovery plan,
because the primary management
objective of the protected sites is not
always to protect only golden
paintbrush. However, we find that the
goal of the criterion, a significant
number of populations under
conservation ownership protective of
the species that are likely to be selfsustaining over time, has been greatly
exceeded. Forty-five of the 48 golden
paintbrush sites are in either public
ownership; are owned by a
conservation-oriented, nongovernmental
organization; or are under conservation
easement (Service 2019, p. 62). Such
ownership is expected to protect sites
from development and land use that
would have long-term, wide-ranging
deleterious effects on this species.
Additionally, 37 sites currently have
management practices that at least
preserve essential characteristics of
golden paintbrush habitat, and 24 sites
have management plans and resources
for their implementation for multiple
years (Service 2019, pp. 40, 42–44). In
addition, at least two of the five
conservation easement sites are also
enrolled in the Service’s Partners for
Fish and Wildlife Program, which
provides technical and financial
assistance to private landowners to
restore, enhance, and manage private
land to improve native habitat. At least
3 sites in Washington and 14 sites in
Oregon also support other prairiedependent species currently listed as
endangered or threatened species under
the Act, and another 5 are part of
designated critical habitat for one of
these species. Therefore, we anticipate
prairie management or maintenance will
be ongoing at these golden paintbrush
sites for the foreseeable future. Two of
the three extant sites in British
Columbia that are managed by Parks
Canada are also located within
designated ‘‘ecological reserves’’
(Service 2019, p. 14). The level of
management specific to golden
paintbrush varies at each site, but all
sites are generally being managed to
conserve or restore native prairie or
grassland habitats. For additional detail
on species management status at sites,
see the discussion under Summary of
Biological Status and Threats, below.
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
Criterion 3 for Delisting
Criterion 3 is that genetic material, in
the form of seeds adequately
representing the geographic distribution
or genetic diversity within the species,
is stored in a facility approved by the
Center for Plant Conservation.
Progress on Criterion 3
This recovery criterion is met. Seeds
are being stored at two approved
facilities, the Rae Selling Berry Seed
Bank at Portland State University and
the Miller Seed Vault at the University
of Washington Botanic Garden. In
addition, the active seed production
programs at the Center for Natural
Lands Management in the South Puget
Sound, Washington, and two smaller
nurseries in the North Puget Sound,
Washington, continue to provide golden
paintbrush seeds to land managers for
population augmentation and prairie
restoration projects. Production
programs were started using seeds from
nearly all the populations extant at the
time of listing to maintain existing
genetic diversity across the species’
historical range and to allow for the
greatest opportunity for local adaptation
at reintroduction sites.
Criterion 4 for Delisting
Criterion 4 is that post-delisting
monitoring of the condition of the
species and the status of all individual
populations is ready to begin.
Progress on Criterion 4
We have developed a post-delisting
monitoring plan in cooperation with our
lead State partners in Washington
(Washington Department of Natural
Resources (WDNR)) and in Oregon
(Oregon Department of Agriculture
(ODA)). The final post-delisting
monitoring plan is available for public
review on https://www.regulations.gov
under Docket No. FWS–R1–ES–2020–
0060. We anticipate that the WDNR’s
WNHP and ODA will coordinate future
monitoring. In the post-delisting
monitoring plan, we include the
monitoring of, at a minimum, all
populations established and counted in
2018 that were identified in the SBR
(Service 2019, pp. 12–13). These
populations will be monitored every
other year after final delisting for a 5year period (i.e., three times, in years 1,
3, and 5, after this final rule is effective).
Several key prairie conservation
partners may choose to monitor these
golden paintbrush sites more frequently
and may also choose to monitor
additional golden paintbrush sites as
more become established across the
species’ range in Oregon and
Washington. Parks Canada oversees
PO 00000
Frm 00048
Fmt 4700
Sfmt 4700
periodic monitoring of the three extant
populations within British Columbia,
Canada. Therefore, this recovery
criterion is met.
Criterion 5 for Delisting
Criterion 5 is that post-delisting
procedures for the ecological
management of habitats for all
populations of golden paintbrush have
been initiated.
Progress on Criterion 5
This criterion has not been met as
phrased in the recovery plan, as
procedures for ecological management
for all populations are not in place.
However, we find that the intent of this
criterion has been met because a
substantial proportion of known golden
paintbrush sites, i.e., 37 out of 48,—
more than the 20 populations originally
envisioned for these recovery criteria—
meet this criterion. At least 24 of the 48
golden paintbrush sites have had prairie
or grassland management plans in place
for multiple years. An additional 13
sites that lack a long-term management
plan for the golden paintbrush receive
basic maintenance to preserve the
prairie characteristics of golden
paintbrush habitat (Service 2019, pp.
42–44). As described earlier, significant
strides have been made in the ecological
management techniques for restoration
and maintenance of prairie landscapes
and the reintroduction and management
of golden paintbrush at these and other
sites. The current level of management
varies across extant sites, influenced by
need, conservation partner capacity, and
funding availability. We anticipate
ongoing management at a minimum of
37 of these sites, although the level of
management will continue to vary
across sites based on these same factors
(Service 2019, pp. 40, 42–44) (see
additional discussion regarding ongoing
site management under Summary of
Biological Status and Threats, below).
The most actively managed sites may
include plantings, fencing, prescribed
fire, herbicide use for weed control,
mowing, and controlled public use. As
described above under Criterion 2 for
Delisting, at least 17 sites currently
contain multiple, prairie-dependent
species and an additional 5 sites are
designated critical habitat for another
prairie-dependent species. Those golden
paintbrush sites that support multiple,
prairie-dependent species listed under
the Act are anticipated to receive the
most consistent ecological management
into the future. While this recovery
criterion has not been fully achieved
(i.e., not all populations have postdelisting management procedures in
place), ecological management of habitat
E:\FR\FM\19JYR1.SGM
19JYR1
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
is expected to occur on the vast majority
of the known sites and management will
occur on far more than the originally
projected 15 sites identified above
under Criterion 2 for Delisting.
With the more recently identified
threat of hybridization from harsh
paintbrush (Castilleja hispida),
additional measures are being
implemented and refined to address the
impacts to golden paintbrush on
contaminated sites and prevent the
spread of harsh paintbrush to
uncontaminated golden paintbrush sites
in the South Puget Sound geographic
area in Washington. The Service has
developed a strategy and guidance
document for securing golden
paintbrush sites and outlining solutions
necessary for the long-term protection of
golden paintbrush from hybridization
(Service et al. 2021, entire). In addition,
the Service has signed a memorandum
of understanding (MOU) with our State
conservation partners to ensure
hybridization is contained and the
conservation strategy is followed to
benefit golden paintbrush while
supporting recovery of other sympatric
(occurring within the same geographical
area) prairie species listed under the Act
(Service et al. 2020, entire). We provide
more information and discussion on the
hybridization conservation strategy and
how it fits into the conservation of
golden paintbrush in Summary of
Biological Status and Threats, and our
response to (15) Comment, below.
Regulatory and Analytical Framework
ddrumheller on DSK120RN23PROD with RULES1
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
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
(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
species’ expected response and the
effects of the threats—in light of those
actions and conditions that will
ameliorate the threats—on an
individual, population, and species
level. We evaluate each threat and its
expected effects on the species, then
analyze the cumulative effect of all of
the threats on the species as a whole.
We also consider the cumulative effect
of the threats in light of those actions
and conditions that will have positive
effects on the species, such as any
existing regulatory mechanisms or
conservation efforts. The Secretary
determines whether the species meets
the definition of an ‘‘endangered
species’’ or a ‘‘threatened species’’ only
after conducting this cumulative
analysis and describing the expected
effect on the species now and in the
foreseeable future.
The Act does not define the term
‘‘foreseeable future,’’ which appears in
the statutory definition of ‘‘threatened
species.’’ Our implementing regulations
at 50 CFR 424.11(d) set forth a
framework for evaluating the foreseeable
future on a case-by-case basis. The term
foreseeable future extends only so far
into the future as we can reasonably
determine that both the future threats
and the species’ responses to those
threats are likely. In other words, the
PO 00000
Frm 00049
Fmt 4700
Sfmt 4700
46095
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 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.
For species that are already listed as
endangered or threatened species, this
analysis of threats is an evaluation of
both the threats currently facing the
species and the threats that are
reasonably likely to affect the species in
the foreseeable future following the
downlisting or delisting and the
removal of the Act’s protections. A
recovered species is one that no longer
meets the Act’s definition of an
endangered species or a threatened
species. For the golden paintbrush, we
consider 30 years to be a reasonable
period of time within which reliable
predictions can be made for stressors
and species’ response. This time period
includes multiple generations of the
golden paintbrush, generally includes
the term of and likely period of response
to many of the management plans for
the species and/or its habitat, and
encompasses planning horizons for
prairie habitat conservation efforts (e.g.,
Dunwiddie and Bakker 2011, pp. 86–88;
Service 2011, entire; Altman et al. 2017,
pp. 6, 20); additionally, various global
climate models and emission scenarios
provide consistent predictions within
that timeframe (Intergovernmental Panel
on Climate Change (IPCC) 2014, p. 11).
We consider 30 years a relatively
conservative timeframe in view of the
long-term protection afforded to 93
percent of the species’ occupied
populations (45 of 48), which occur on
conserved/protected lands (Service
2019, p. 62).
Analytical Framework
The SBR documents the results of our
comprehensive biological review of the
best scientific and commercial data
regarding the status of the species. The
report does not represent our decision
E:\FR\FM\19JYR1.SGM
19JYR1
46096
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
ddrumheller on DSK120RN23PROD with RULES1
on whether the species should be
delisted 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 report, which can
be found at Docket FWS–R1–ES–2020–
0060 on https://www.regulations.gov.
To assess golden paintbrush 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. We
use this information to inform our
regulatory decision.
Summary of Biological Status and
Threats
Below, we review the biological
condition of the species and its
resources, and the threats that influence
the species’ condition in order to assess
the species’ overall viability and the
risks to that viability. In addition, the
SBR (Service 2019, entire) documents
our comprehensive biological status
review for the species, including an
assessment of the potential threats to the
species. The following potential threats
were identified for this species at the
time of listing: (1) Succession of prairie
and grassland habitats to shrub and
forest lands (due to fire suppression,
interspecific competition, and invasive
species); (2) development of property for
commercial, residential, and
agricultural use; (3) low potential for
expansion and refugia due to
constriction of habitat (from
surrounding development or land use);
(4) recreational picking (including
associated trampling); and (5) herbivory
(predation on plants and seeds) (62 FR
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
31740; June 11, 1997). For our analysis,
we assessed the influence of these
potential threats on the current status of
the species, as well as the influence of
two potential threats not considered at
the time of listing: hybridization of
golden paintbrush with harsh
paintbrush, and the impacts of climate
change. We also assessed current
voluntary and regulatory conservation
mechanisms relative to how they reduce
or ameliorate existing threats to golden
paintbrush.
Habitat Loss
At the time of listing, the principal
cause of ongoing habitat loss was
succession of prairie and grassland
habitats to shrub and forest due to fire
suppression, interspecific competition,
and invasive species (62 FR 31740; June
11, 1997). The potential for
development at, or surrounding, extant
sites for commercial, residential, and
agricultural purposes also posed a threat
to the golden paintbrush at the time of
listing. Both of these threat factors were
preventing or limiting extant
populations from expanding and
recruiting into new or adjacent areas
and afforded no refugia for the species
in the case of catastrophic events.
Currently, ongoing prairie or
grassland management or maintenance
occurs at the majority of extant golden
paintbrush sites. This management
includes removal or suppression of trees
and both native and nonnative woody
shrubs, as well as control of nonnative,
invasive grassland plant species through
a number of different approaches (e.g.,
mowing, prescribed fire, mechanical
removal, selective-herbicide
application, restoration reseeding, etc.).
Most golden paintbrush sites have either
had prairie or grassland management
plans in place for multiple years or
receive basic maintenance to preserve
the prairie characteristics of golden
paintbrush habitat (Service 2019, pp.
42–44). Three golden paintbrush sites in
Washington also currently support other
prairie- or grassland-dependent species
listed under the Act—the endangered
Taylor’s checkerspot butterfly
(Euphydryas editha taylori) and three
threatened subspecies of Mazama
pocket gopher (Thomomys mazama
spp.) (Olympia pocket gopher
(Thomomys mazama pugetensis),
Tenino pocket gopher (Thomomys
mazama tumuli), and Yelm pocket
gopher (Thomomys mazama
yelmensis))—while an additional five
sites in Washington are included in
designated critical habitat for the
Taylor’s checkerspot butterfly.
Although these five critical habitat
sites are currently unoccupied by the
PO 00000
Frm 00050
Fmt 4700
Sfmt 4700
Taylor’s checkerspot butterfly, they
were designated because they were
found to be essential for the
conservation of the butterfly (78 FR
61506; October 3, 2013). Harsh
paintbrush (Castilleja hispida) is a host
plant for Taylor’s checkerspot butterfly
in the South Puget Sound geographic
area in Washington. As we discuss
further below (see Hybridization),
golden paintbrush generally cannot cooccur with harsh paintbrush due to the
threat of hybridization. However, as we
continue to work with our conservation
partners to follow the hybridization
strategy and guidance document to
prioritize sites for both golden
paintbrush and Taylor’s checkerspot
butterfly we also continue to explore
opportunities to conserve both species
on individual sites where appropriate.
In addition, at least 14 golden
paintbrush sites in Oregon’s Willamette
Valley currently support one or more
other prairie- or grassland-dependent
species listed under the Act that do not
present the threat of hybridization—the
endangered Fender’s blue butterfly
(Icaricia icarioides fenderi), endangered
Willamette daisy (Erigeron decumbens),
threatened Kincaid’s lupine (Lupinus
oreganus var. kincaidii, listed as
Lupinus sulphureus ssp. kincaidii), and
threatened Nelson’s checker-mallow
(Sidalcea nelsoniana) (Institute for
Applied Ecology 2019, in litt.).
We expect a number of golden
paintbrush sites in both Washington and
Oregon to continue to be managed in a
way that supports the recovery of other
prairie- or grassland-dependent species
in addition to the long-term
conservation of the golden paintbrush.
As long as periodic management or
maintenance continues to occur at
golden paintbrush sites across the
species’ range, the threat of prairie or
grassland succession is expected to
remain adequately addressed into the
foreseeable future. State and Federal
management plans include specific
objectives to continue to protect and
conserve the golden paintbrush at a
number of sites. States, Federal
agencies, and conservation
organizations have invested significant
resources into golden paintbrush
recovery, as well as general prairie and
grassland restoration and conservation
for a variety of at-risk, prairie-dependent
species. We do not anticipate habitat for
these prairie-dependent species to
contract further given the limited
amount of remaining prairie habitat and
the long-term investments conservation
partners have made, and continue to
make, to restore, rebuild, maintain, and
conserve these relatively rare regional

ecosystems (Dunwiddie and Bakker
2011, entire; Center for Natural Lands
Management 2012, in litt., entire; The
News Tribune 2014, in litt.; Altman et
al. 2017, entire; The Nature
Conservancy 2019, in litt., entire).
Golden paintbrush now occurs within
48 separate populations as a result of
the numerous reintroduction efforts
implemented to recover this species.
Only three of these populations are on
lands possibly subject to future
development. The remaining 45
populations are all under some type of
public or conservation ownership
(Service 2019, pp. 11–14). Of the 48
extant populations, at least 81 percent
(n=39) are on land with some known
level of protected status (at a minimum,
formally protected as a natural area or
other such designation, although not all
of these designations are permanent)
(Service 2019, pp. 42–44). In addition,
of the 39 populations with some
protected land status, 19 also include
stipulations for, or statements of specific
protection of, perpetual management of
the golden paintbrush.
Although the total area occupied by
the golden paintbrush at 19 of the 48
sites is relatively small (less than 0.4
hectare (ha) (1 acre (ac)), 14 of the 48
sites have between 0.4 to 1.6 occupied
ha (1 to 3.9 ac), and another 14 of the
48 sites have from between 2 to 18.6
occupied ha (5 to 46 ac). We lack this
information at one site (Service 2019,
pp. 37–38). All but 4 of the 48 sites have
available land for future golden
paintbrush population expansion or
shifts in distribution. Of the 33 sites
with less than 2 ha (5 ac) of occupied
habitat, 10 have an estimated range of
0.8 to 2 ha (2 to 5 ac) of additional
habitat for expansion, and at least 13
have an estimated range of 2 to 6 ha (5
to 15 ac) of additional habitat for future
expansion (Service 2019, pp. 37–38). In
addition, the species is much less
reliant on expanding site-use and
refugia than at the time of listing, when
only 10 extant populations of the golden
paintbrush remained. The
reintroduction and seed production
techniques developed for golden
paintbrush recovery have provided the
means to more easily establish or
reestablish populations at prairie
restoration sites than were previously
possible. Many of these sites have been
specifically acquired for their potential
overall size, conservation value, and
conservation status. The golden
paintbrush has been reintroduced and
established at prairie restoration sites
that are well-distributed across the
species’ historical range, well beyond
the 10 extant sites at the time of listing.
As a result of these conditions, we do
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
not anticipate development in or around
these sites to become a threat to the
golden paintbrush in the foreseeable
future.
Recreational Picking and Trampling
At the time of listing, we considered
overutilization from recreational picking
(flowers) to be a threat (62 FR 31740;
June 11, 1997). Our concern with
recreational picking or collection of
flowers was that it would reduce overall
potential seed-set at a population.
Concern has also been noted regarding
the direct harvesting of seed capsules
(Dunwiddie 2018, in litt.). Although
there is evidence of occasional
recreational or possible commercial
collection of capsules that reduced the
amount of seed available on a site,
collection is no longer considered a
significant stressor to the species across
its range (Service 2019, p. 47). In
addition, the current number of
established and protected golden
paintbrush populations, many with
limited or restricted access, largely
ameliorates this previously identified
threat. We acknowledge that the golden
paintbrush is likely a desirable species
for some gardeners or plant collectors.
However, when delisted (see DATES,
above), golden paintbrush seeds or
plants are likely to become available
through controlled sale to the public
from regional prairie conservation
partners and/or regional native plant
nurseries, similar to what occurs with
other non-listed prairie plant species.
For these reasons, we do not expect the
possible collection of golden paintbrush
flowers or seeds to become a threat to
the species in the foreseeable future.
At the time of listing, we identified
trampling of golden paintbrush plants
by recreationalists as impacting the
species at some sites with high levels of
public use, especially where and when
associated with recreational picking of
golden paintbrush flowers. Although
some risk of trampling to plants will
always be present across public sites
(e.g., State parks, national wildlife
refuges), most sites often have some
level of restricted access when golden
paintbrush plants are in bloom (e.g.,
fenced from deer or inaccessible to the
public) or there are defined walking or
viewing areas. Therefore, when
compared with the potential impact of
trampling at the time of listing, the
current impact is likely insignificant,
due to the number of reestablished
golden paintbrush populations, the large
size of many of these sites, and
considerable abundance of golden
paintbrush plants at some of these sites.
For the above reasons, we also do not
PO 00000
Frm 00051
Fmt 4700
Sfmt 4700
46097
anticipate that trampling will become a
threat in the foreseeable future.
Herbivory
At the time of listing, we considered
predation (herbivory) on the golden
paintbrush by native (voles and deer)
and introduced (rabbits) species to be a
threat to the plant (62 FR 31740; June
11, 1997); however, the best available
information does not indicate it is a
current or future threat. Although deer
and elk exhibit herbivory on the golden
paintbrush at some sites, there is annual
and site-specific variability in the
overall level of herbivory (Service 2019,
p. 48; Martin 2021, p. 9). Herbivory
impacts from rabbits and voles on the
golden paintbrush have not been
broadly or consistently observed and
also appear to be variable across sites
and years. Where herbivory by deer or
rabbits or both has been significant,
control with fencing has been
successfully implemented, but
controlling herbivory through fencing
over large areas is limited by cost
(Service 2019, p. 48). In addition,
encouraging localized reduction of deer
populations through lethal removal near
some sites (Washington Department of
Fish and Wildlife 2019, in litt.; Pelant
2019, in litt.) and installing raptor perch
poles to control rodents and rabbits at
some sites are also being implemented
to reduce impacts of herbivory on the
golden paintbrush (Service 2019, p. 48).
As a consequence of the significant
increase in the number of golden
paintbrush populations that have been
successfully established across the
species’ range since it was listed, and
because the impact of herbivory is being
adequately managed in at least a portion
of those sites where noted as significant
(potential site- or population-level
effect), we conclude predation
(herbivory) no longer has a significant
impact across the majority of the golden
paintbrush’s 48 sites/populations, nor at
the species level, and it is unlikely to
become a threat to the species in the
foreseeable future.
Hybridization
As noted above, a potential threat to
the golden paintbrush identified after
the species was listed in 1997 was the
impact of hybridization with the harsh
paintbrush. The harsh paintbrush is one
of the host plants introduced to prairie
sites targeted for endangered Taylor’s
checkerspot butterfly recovery efforts.
Our 2007 5-year status review
recommended, ‘‘the evaluation of the
potential for genetic contamination of
golden paintbrush populations by
hybridization with other species of
Castilleja’’ (Service 2007, p. 15). After
E:\FR\FM\19JYR1.SGM
19JYR1
ddrumheller on DSK120RN23PROD with RULES1
46098
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
initial evaluation, the potential risk of
hybridization was considered relatively
low and manageable (Kaye and
Blakeley-Smith 2008, p. 13). However,
after further evaluation and additional
observations in the field, hybridization
with the harsh paintbrush has now been
identified as a significant potential
threat to golden paintbrush populations
where the two species occur together or
in close proximity (Clark 2015, entire;
Sandlin 2018, entire). Three former
golden paintbrush recovery sites have
now been discounted by the Service for
the purposes of recovery due to the level
of hybridization at these sites (Service
2019, p. 15). At least one other site is
currently vulnerable to the effects of
hybridization, but management efforts
to date (removal of plants that exhibit
hybrid characteristics and creation of a
zone of separation between harsh
paintbrush and golden paintbrush areas
at the site) have maintained this golden
paintbrush population. Currently,
hybridization appears to be confined to
those areas located in the South Puget
Sound prairie region where both species
of Castilleja were used at some of the
same habitat restoration sites. The only
known incident of hybridization outside
of this region was at Steigerwald Lake
National Wildlife Refuge in
southwestern Washington, where we
unknowingly used a seed mix that
included the harsh paintbrush. This site
has since been eradicated of both
Castilleja species, but we anticipate
reintroducing the golden paintbrush to
the site in the future (Ridgefield
National Wildlife Refuge Complex 2019,
in litt., entire).
As a response to this emerging threat,
efforts were implemented, and are
ongoing, to reduce or eliminate the risk
of hybridization to the golden
paintbrush. These include efforts such
as maintaining isolated growing areas
for the golden paintbrush and harsh
paintbrush at native seed production
facilities used in prairie restoration
efforts, maintaining buffers between
golden paintbrush and harsh paintbrush
patches at sites where both species are
currently present, and delineating
which of the two species will be used
at current and future prairie
conservation or restoration sites. We
recently developed a strategy and
guidance document for securing golden
paintbrush sites to address containment
of hybridization at existing
contaminated sites and prevention of
unintentional spread of hybridization to
other regions within the golden
paintbrush’s range, specifically north
Puget Sound and the Willamette Valley
(Service et al. 2021, entire). We have
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
also entered into an associated MOU
with the Washington Department of
Fish and Wildlife (WDFW) and WDNR
to ensure the strategy is implemented as
agreed to by all prairie conservation
partners in the range of the golden
paintbrush (Service et al. 2020, entire).
The three agencies have authority over
these species and will oversee most
prairie restoration efforts in
Washington, particularly in South Puget
Sound. This MOU is expected to
facilitate awareness and compliance
with the hybridization strategy and
guidance by our prairie conservation
partners across the range of the golden
paintbrush. The formal adoption and
implementation of the hybridization
strategy and guidance is expected to
prevent hybridization from becoming a
threat to the golden paintbrush in the
foreseeable future. Please see our
response to (12) Comment, below, for
additional discussion regarding
hybridization.
Climate Change
At the time of listing, the potential
impacts of climate change on the golden
paintbrush were not discussed. The
term ‘‘climate’’ refers to the mean and
variability of relevant quantities (i.e.,
temperature, precipitation, wind) over
time (IPCC 2014, pp. 119–120). The
term ‘‘climate change’’ thus refers to a
change in the mean or variability of one
or more measures of climate (e.g.,
temperature or precipitation) that
persists for an extended period,
typically decades or longer, whether the
change is due to internal processes or
anthropogenic changes (IPCC 2014, p.
120).
Scientific measurements spanning
several decades demonstrate that
changes in climate are occurring. In
particular, warming of the climate
system is unequivocal, and many of the
observed changes in the last 60 years are
unprecedented over decades to
millennia (IPCC 2014, p. 2). The current
rate of climate change may be as fast as
any extended warming period over the
past 65 million years and is projected to
accelerate over the next 30 to 80 years
(National Research Council 2013, p. 5).
Thus, rapid climate change is adding to
other sources of extinction pressures,
such as land use and invasive species,
which will likely place extinction rates
in this era among just a handful of the
severe biodiversity crises observed in
Earth’s geological record (American
Association for the Advancement of
Science (AAAS) 2014, p. 7).
Global climate projections are
informative, and in some cases, the only
or the best scientific information
available for us to use. However,
PO 00000
Frm 00052
Fmt 4700
Sfmt 4700
projected changes in climate at the
global scale and related impacts can
vary substantially across and within
different regions of the world (e.g., IPCC
2013 and 2014, entire) and within the
United States (Melillo et al. 2014,
entire). Therefore, we use ‘‘downscaled’’
projections when they are available and
have been developed through
appropriate scientific procedures,
because such projections provide higher
resolution information that is more
relevant to spatial scales used for
analyses of a given species (see Glick et
al. 2011, pp. 58–61, for a discussion of
downscaling).
Climate change trends predicted for
the Pacific Northwest (Oregon,
Washington, Idaho, and Montana)
broadly consist of an increase in annual
average temperature; an increase in
extreme precipitation events; and, with
less certainty, variability in annual
precipitation (Bachelet et al. 2011, p.
413; Dalton et al. 2013, pp. 31–38, figure
1.1; Snover et al. 2013, pp. 5–1–5–4).
Based on a 2014 climate change
vulnerability assessment, the golden
paintbrush was considered ‘‘presumed
stable’’ (Gamon 2014, entire). After the
completion of the SBR (Service 2019,
entire), a new assessment was
conducted on sites in Washington,
which evaluated only the populations
extant at the time of listing (11 extant
and 11 populations that were extirpated;
none of the 10 outplanted sites in
Washington); this new assessment
considered golden paintbrush as
‘‘highly vulnerable’’ to climate change
(Young et al. 2016, entire; Kleinknecht
et al. 2019, entire). Please see our
response to (10) Comment, below, for
more discussion regarding this new
information.
Prolonged or more intense summer
droughts are likely to increase in the
Pacific Northwest due to climate change
(Snover et al. 2013, p. 2–1). Regional
climate change literature suggests that
prairie ecosystems were established
under warmer and drier conditions and
are unlikely to be disadvantaged from
future increased summer drought
(Bachelet et al. 2011, p. 417). However,
although the golden paintbrush senesces
as the prairies dry out in the summer,
increased intensity or length of drought
conditions will likely stress plants and
increase mortality, resulting in reduced
numbers of individuals in populations
at less-than-optimal sites (Kaye 2018, in
litt.).
As is the case with all stressors we
assess, even if we conclude that a
species is currently affected or is likely
to be affected in a negative way by one
or more climate-related impacts, it does
not necessarily follow that the species
E:\FR\FM\19JYR1.SGM
19JYR1
ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
meets the definition of an ‘‘endangered
species’’ or a ‘‘threatened species’’
under the Act.
Predicted environmental changes
resulting from climate change may have
both positive and negative effects on the
golden paintbrush, depending on the
extent and type of impact and
depending on site-specific conditions
within each habitat type. The primary
predicted negative effect includes
drought conditions resulting in
inconsistent growing seasons. Likewise,
future temperature changes may
influence the timing of native prairie
plant phenology, which could lead to
asynchronies with pollinators (Reed et
al. 2019, entire). This effect will likely
be buffered by the ability of the golden
paintbrush to survive in a range of soil
conditions, as is evident by its
establishment on a wide variety of sites
across its 300-mile geographic range,
with a number of different host plants,
and under a range of precipitation
levels. We have not identified any
predicted environmental effects from
climate change that may be positive for
the golden paintbrush at this time.
Climate change could result in a decline
or change in bumble bee diversity
within the range of the golden
paintbrush (Soroye et al. 2020, entire);
the bumble bee is an important
pollinator for the golden paintbrush
(Service 2019, pp. 6–7). However, there
are limited data at this time to indicate
the potential loss of bumble bee
diversity is a specific and present threat
to the golden paintbrush. Also,
observations of reduced seed production
at some Washington sites in recent years
(2019–2021) could be the result of
recent drought events, although it
remains unclear how these observations
translate to population abundance and
trends over time. Golden paintbrush
populations can experience high
variability in abundance between years
(Fertig 2021, pp. 24–27), and while
climate change is a stressor, given the
species’ high abundance and
distribution across the 300-mile range
from British Columbia to Oregon, we
expect the golden paintbrush has
sufficient resiliency and redundancy to
remain viable into the foreseeable
future. Establishing plant populations
such as the golden paintbrush across the
full geographic and climatic range of
Pacific Northwest prairies has been
identified as a ‘‘climate-smart’’ strategy
given the extensive north-south range
encompassing variable temperature and
precipitation patterns (Bachelet et al.
2011, p. 420). The species appears to
have sufficient resiliency and
redundancy across its range to maintain
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
sufficient viability during drought years.
As evidence, the last 4 years of
monitoring (2017–2020) represent the 4
years with greatest abundance
rangewide despite extreme drought
experienced between 2015 and 2016 in
Oregon and Washington (Fertig 2021, p.
30; National Oceanic and Atmospheric
Administration National Integrated
Drought Information System (NOAA
NIDIS) 2022, entire). In addition, the
year 2020 also represents the secondhighest abundance of golden paintbrush
in the State of Washington at 202,208
flowering plants, which was a 47.8
percent increase from 136,846 in 2019.
Additionally, several outplantings have
been initiated at new locations since
2018 in Washington, and we are
continuing to work with our partners to
plan new outplantings across the
species’ range that will further add to
the species’ resiliency and redundancy.
In summary, climate change is
affecting, and will continue to affect,
temperature and precipitation events
within the range of the golden
paintbrush. The extent, duration, and
impact of those changes are unknown,
but could potentially increase or
decrease precipitation in some areas and
increase temperatures found within the
range of the golden paintbrush. Golden
paintbrush may experience climate
change-related effects in the future,
most likely at the individual or local
population scale; however, we
anticipate the species will remain
viable, because: (1) It is more resilient
than at the time of listing as a result of
increased abundance, number of sites,
and geographic distribution in a variety
of ecological settings, contributing to the
species’ resiliency, redundancy, and
representation; (2) available information
indicates the golden paintbrush is
somewhat adaptable to some level of
future variation in climate conditions
(Service 2019, pp. 22–25, 45); (3) there
are ongoing efforts to expand the golden
paintbrush to additional suitable sites
across the species’ range; and (4) we
now have the technical ability to
effectively and more readily establish
populations, which could help to
mitigate future population losses.
Therefore, based upon the best available
scientific and commercial information,
we conclude that climate change does
not currently pose a threat to the golden
paintbrush, nor is it likely to become a
threat to the golden paintbrush in the
foreseeable future (next 30 years).
Voluntary and Regulatory Conservation
Mechanisms
For current federally listed species,
we consider existing regulatory
mechanisms relative to how they reduce
PO 00000
Frm 00053
Fmt 4700
Sfmt 4700
46099
or ameliorate threats to the species
absent the protections of the Act.
Therefore, we examine whether other
regulatory mechanisms would remain in
place if the species were delisted, and
the extent to which those mechanisms
will continue to help ensure that future
threats will be reduced or eliminated. In
the final listing rule (62 FR 31740; June
11, 1997), we noted that habitat
management for the golden paintbrush
was not assured, despite the fact that
most populations occurred in areas
designated as reserves or parks that
typically afforded the golden paintbrush
and its habitat some level of protection
through those designations. As
discussed in our SBR (Service 2019, pp.
47–52), the threat of habitat loss from
potential residential or commercial
development has decreased since the
time of listing due to the establishment
of new golden paintbrush populations
on protected sites. Although a few
privately owned sites are still at some
potential risk, development is no longer
considered a significant threat to the
viability of the golden paintbrush due to
the number of sites largely provided
protection from development (Service
2019, pp. 12–14).
Federal
Sikes Act—The Sikes Act (16 U.S.C.
670 et seq.) provides the authority and
defines the responsibilities to facilitate
effectual planning, development,
maintenance, and coordination of
wildlife, fish, and game conservation
and rehabilitation on military
installations. The Sikes Act requires that
conservation goals are cooperatively
developed and recorded in a planning
document called an integrated natural
resources management plant (INRMP).
One golden paintbrush population
currently occurs on a Federal military
installation (Forbes Point, Naval Air
Station Whidbey Island in Island
County, Washington) and is managed
under an INRMP (U.S. Department of
Defense (USDOD) 2013, pp. 3–7)
authorized by the Sikes Act. Special
management and protection
requirements for golden paintbrush
habitat in the INRMP include
maintenance of a 10-ac management
area for the species, including:
maintaining and improving a fence
around the population to exclude both
people and herbivores; posting signs
that state the area is accessible to
‘‘authorized personnel only’’; mowing
and hand-cutting competing shrubs in
the area; outplanting nursery-grown
plants from seeds previously collected
onsite; and implementing additional
habitat management actions, such as
controlled burns or herbicide control of

competing vegetation, that are identified
in the future to enhance the golden
paintbrush population (USDOD 2013,
pp. 3–7). These protections are effective
in protecting the golden paintbrush on
this site and are expected to continue in
the absence of protections under the Act
because the Sikes Act mandates the
Department of Defense to conserve and
rehabilitate wildlife, fish, and game on
military installations.
National Wildlife Refuge System
Improvement Act—Ten golden
paintbrush populations currently occur
on National Wildlife Refuge (NWR)
lands (Dungeness NWR in Washington;
and Ankeny, William L. Finley,
Tualatin River, and Baskett Slough
NWRs in Oregon). As directed by the
National Wildlife Refuge System
Improvement Act of 1997 (Pub. L. 105–
57), refuge managers have the authority
and responsibility to protect native
ecosystems, fulfill the purposes for
which an individual refuge was
founded, and implement strategies to
achieve the goals and objectives stated
in management plans. For example,
William L. Finley NWR (Benton County,
Oregon) includes extensive habitat for
the golden paintbrush, including four
known populations, while a number of
additional NWRs in Oregon (Ankeny
NWR, Marion County; Tualatin River
NWR, Washington County; and Baskett
Slough NWR, Polk County) and
Washington (Dungeness NWR, Clallam
County) each also support at least one
golden paintbrush population.
The Willamette Valley comprehensive
conservation plan (CCP) for William L.
Finley, Ankeny, and Baskett Slough
NWRs is a land management plan
finalized in 2011 with a 15-year term
that directs maintenance, protection,
and restoration of the species and its
habitat and identifies specific objectives
related to establishment of populations
and monitoring, as well as related
habitat maintenance/management
(Service 2011, pp. 2–45–2–46, 2–66–2–
70). Given the 15-year timeframe of
CCPs, these protections would remain
in place until at least 2026, regardless of
the golden paintbrush’s Federal listing
status.
Tualatin River NWR finalized a CCP
in 2013 (Service 2013a, entire), and
although it does not have conservation
actions specific to the golden paintbrush
identified in the plan, it does have
maintenance and management activities
for oak savanna habitat on the NWR,
which supports the golden paintbrush
(Service 2013a, pp. 4–9–4–10). These
activities include various methods (e.g.,
mechanical and chemical) for reducing
encroachment of woody species,
controlling nonnative and invasive

plant species, and reestablishing native
grasses and forbs. Given the 15-year
timeframe of CCPs, protections outlined
in the Tualatin River NWR CCP are
expected to remain in place until at
least 2028, regardless of the golden
paintbrush’s Federal listing status.
Dungeness NWR also finalized a CCP
in 2013 (Service 2013b, entire). The CCP
does not have any conservation actions
specific to the golden paintbrush
identified; however, it does identify
general actions taken to control
nonnative and invasive plant species
that invade habitats on the refuge,
including those inhabited by the golden
paintbrush (Service 2013b, pp. 4–44–4–
45). The golden paintbrush population
at this NWR’s headquarters continues to
be maintained and protected.
In addition to specific protections for
the golden paintbrush provided under
CCPs, the species is permanently
protected by the mission of all NWRs to
manage their lands and waters for the
conservation of fish, wildlife, and plant
resources and their habitats.
National Park Service Organic Act—
One golden paintbrush site currently
occurs on National Park Service (NPS)
lands (American Camp, San Juan Island
National Historical Park, Washington).
The NPS Organic Act of 1916 (54 U.S.C.
100101 et seq.), as amended, states the
NPS will promote and regulate the use
of the National Park system to conserve
the scenery, natural and historic objects,
and wildlife therein, to provide for the
enjoyment of the same in such manner
and by such means as will leave them
unimpaired for the enjoyment of future
generations (54 U.S.C. 100101(a)).
Further, in title 36 of the Code of
Federal Regulations (CFR) at
§ 2.1(a)(1)(ii), NPS regulations
specifically prohibit possessing,
destroying, injuring, defacing, removing,
digging, or disturbing from their natural
state plants, or the parts or products
thereof, on lands under NPS
jurisdiction. This prohibition extends to
the golden paintbrush where it exists on
NPS-managed lands. In addition, the
General Management Plan for the San
Juan Island National Historical Park
includes the NPS’s goal of restoring a
prairie community that support
functions and values of native habitat,
including habitat for native wildlife and
rare species, such as the golden
paintbrush (NPS 2008, p. 249).
Endangered Species Act—The golden
paintbrush often co-occurs with other
plant and animal species that are listed
under the Act, such as the endangered
Willamette daisy and endangered
Taylor’s checkerspot butterfly.
Therefore, some of the general habitat
protections (e.g., section 7 consultation
PO 00000
Frm 00054
Fmt 4700
Sfmt 4700
and ongoing recovery implementation
efforts, including prairie habitat
restoration, maintenance, and
protection) for these other prairiedependent, listed species will indirectly
extend to some golden paintbrush sites
when we delist the golden paintbrush.
We acknowledge that some sites that
support Taylor’s checkerspot butterfly
will not be available for golden
paintbrush due to the threat of
hybridization between golden and harsh
paintbrush; however, given that
hybridization has only impacted
populations in the South Puget Sound
area of Washington, and the extensive
range of golden paintbrush in other
areas where hybridization is currently
not a threat, we assume that
management for prairie-dependent
species across the range will benefit
golden paintbrush beyond delisting.
Likewise, the hybridization strategy and
guidance document and our partnership
with State agencies in Washington will
ensure that hybridization is minimized
or avoided into the future (Service et al.
2020, entire; Service et al. 2021, entire).
Protections in Canada—The golden
paintbrush in Canada is currently
federally listed as ‘‘endangered’’ under
the Species at Risk Act (SARA)
(COSEWIC 2007, entire). SARA
regulations protect species from harm,
possession, collection, buying, selling,
or trading (Statutes of Canada 2002, c.
29). SARA also prohibits damage to or
destroying the habitat of a species that
is listed as an endangered species. The
population at Trial Island is on
Canadian federal lands protected under
SARA (COSEWIC 2011, in litt., p. 5).
The golden paintbrush is not currently
protected under any provincial
legislation in British Columbia.
However, the golden paintbrush occurs
in the ecological reserves that include
Trial Island and Alpha Islet, which are
protected under the British Columbia
Park Act (COSEWIC 2011, in litt., p. 5).
The British Columbia Park Act allows
lands identified under the Ecological
Reserve Act to be regulated to restrict or
prohibit any use, development, or
occupation of the land or any use or
development of the natural resources in
an ecological reserve (Revised Statutes
of British Columbia 1996, c. 103). This
includes particular areas where rare or
endangered native plants and animals in
their natural habitat may be preserved.
State
Washington Natural Heritage Plan—
Washington State’s Natural Heritage
Plan identifies priorities for preserving
natural diversity in Washington State
(WDNR 2018, entire). The plan aids
WDNR in conserving key habitats that
E:\FR\FM\19JYR1.SGM

ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
are currently imperiled, or are expected
to be imperiled in the future. The
prioritization of conservation efforts
provided by this plan is expected to
remain in place if we delist the golden
paintbrush. The golden paintbrush is
currently identified as a priority 2
species (species likely to become
endangered across their range or in
Washington within the foreseeable
future) in the State’s 2018 plan (WDNR
2018a, in litt., p. 4), which is a recent
change from the species’ priority 1
designation (species are in danger of
extinction across their range, including
Washington) in 2011 (WDNR 2018b, in
litt., p. 2). The State’s conservation
status is not necessarily impacted by
Federal delisting and is ultimately at the
discretion of WDNR. We anticipate that
WDNR will continue to monitor the
species where it occurs on their own
lands and more broadly as a partner in
the post-delisting monitoring plan. We
also anticipate that WDNR will continue
to actively manage their golden
paintbrush sites because these areas are
not only important to the long-term
conservation of golden paintbrush, but
also to other at-risk prairie species.
Washington State Park Regulations
and Management—In Washington, State
park regulations, in general, require an
evaluation of any activity conducted on
a park that has the potential to damage
park resources, and require mitigation
as appropriate (see title 352 of the
Washington Administrative Code).
Wildlife, plants, all park buildings,
signs, tables, and other structures are
protected; removal or damage of any
kind is prohibited (Washington State
Parks and Recreation Commission 2019,
in litt., p. 2). One golden paintbrush site
currently exists on Fort Casey Historical
State Park. One of the objectives for
natural resources on Fort Casey
Historical State Park under the Central
Whidbey State Parks Management Plan
is to protect and participate in the
recovery of the golden paintbrush,
including protecting native plant
communities, managing vegetative
succession, and removing weeds
through integrated pest management
(Washington State Parks and Recreation
Commission 2008, p. 15). The plan
further states that areas where the
golden paintbrush occurs will be
classified as ‘‘heritage affording a high
degree of protection,’’ and the Nass
Natural Area Preserve (also known as
Admiralty Inlet Natural Area Preserve)
is included in the long-term park
boundary to also assure continued
preservation of the golden paintbrush in
this area (Washington State Parks and
Recreation Commission 2008, p. 26).

Oregon Revised Statutes (ORS),
Chapter 564—Oregon Revised Statutes,
chapter 564, ‘‘Wildflowers; Threatened
or Endangered Plants,’’ requires State
agencies to protect State-listed plant
species found on their lands. Any land
action on Oregon land owned or leased
by the State, for which the State holds
a recorded easement, and which results,
or might result, in the taking of an
endangered or threatened plant species,
requires consultation with Oregon
Department of Agriculture staff (see
ORS section 564.115). The golden
paintbrush is currently State-listed as
endangered in Oregon. At this time, no
populations of the golden paintbrush
are known to occur on State lands in
Oregon. However, should populations of
the golden paintbrush occur on Oregon
State lands in the future, the removal of
Federal protections for the golden
paintbrush would not affect State
protection of the species under this
statute.
In summary, conservation measures
and existing regulatory mechanisms
have minimized, and are continuing to
address, the previously identified
threats to the golden paintbrush,
including habitat succession of prairie
and grassland habitats to shrub and
forest lands; development of property
for commercial, residential, and
agricultural use; recreational picking
(including associated trampling); and
herbivory (on plants and seeds). As
indicated above, we anticipate the
majority of these mechanisms will
remain in place regardless of the
species’ Federal listing status.
Cumulative Impacts
When multiple stressors co-occur, one
may exacerbate the effects of the other,
leading to effects not accounted for
when each stressor is analyzed
individually. The full impact of these
synergistic effects may be observed
within a short period of time, or may
take many years before it is noticeable.
For example, high levels of predation
(herbivory) on the golden paintbrush by
deer could cause large temporary losses
in seed production in a population, but
are not generally considered to be a
significant threat to long-term viability,
as populations that are relatively large
and well-distributed should be able to
withstand such naturally occurring
events. However, the relative impact of
predation (herbivory) by deer may be
intensified when it occurs in
conjunction with other factors that may
lessen the resiliency of golden
paintbrush populations, such as
prolonged woody species encroachment
(prairie succession); extensive
nonnative, invasive plant infestations;
PO 00000
Frm 00055
Fmt 4700
Sfmt 4700

or possible increased plant mortality
resulting from the effects of climate
change (i.e., prolonged drought).
Although the types, magnitude, or
extent of potential cumulative impacts
are difficult to predict, we are not aware
of any combination of factors that is
likely to co-occur resulting in significant
negative consequences for the species.
We anticipate that any negative
consequence of co-occurring threats will
be successfully addressed through the
same active management actions that
have contributed to the ongoing
recovery of the golden paintbrush and
the conservation of regional prairie
ecosystems that are expected to
continue into the future.
Summary of Biological Status
To assess golden paintbrush viability,
we evaluated the three conservation
biology principles of resiliency,
redundancy, and representation (Shaffer
and Stein 2000, pp. 306–310). We
assessed the current resiliency of golden
paintbrush sites (Service 2019, pp. 52–
63) by scoring each site’s management
level, site condition, threats addressed,
site abundance of plants, and site
protection, resulting in a high,
moderate, or low condition ranking.
One-third of sites were determined to
have a high condition ranking, one-third
a moderate condition ranking, and onethird a low condition ranking (Service
2019, p. 63). This represents 32 sites in
a moderate or higher condition based on
those important factors directly
informing resiliency of individual sites
or populations within the SBR (Service
2019, p. 63). This number of sites
exceeds the 15 to 20 populations in
stable condition on protected lands that
the recovery criteria identified as
needed to achieve recovery; this
therefore provides sufficient resiliency
for the species.
Golden paintbrush sites are welldistributed across the species’ historical
range and provide representation across
the four geographic areas within that
range (British Columbia, North Puget
Sound, South Puget Sound, and the
Willamette Valley). Multiple sites or
populations exist within each of these
geographic areas, providing a relatively
secure level of redundancy across the
historical range, with the lowest relative
level of redundancy within British
Columbia. The resiliency of the golden
paintbrush is variable across the
historical range given differences in site
or population abundance, level of
management at a site, and site
condition. The best scientific and
commercial data available indicate that
the golden paintbrush is composed of
multiple populations, primarily in
E:\FR\FM\19JYR1.SGM

Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
moderate to high condition (Service
2019, p. 63), which are sufficiently
resilient, well-distributed (redundancy
and representation), mostly in protected
areas, and managed such that they will
be relatively robust or resilient to any
potential cumulative effects to which
they may be exposed.

Summary of Comments and
Recommendations
In our June 30, 2021, proposed rule
(86 FR 34695), we requested that all
interested parties submit written
comments on the proposal by August
30, 2021. We also contacted appropriate
Federal and State agencies, scientific
experts and organizations, and other
interested parties and invited them to
comment on the proposed rule.
Newspaper notices inviting general
public comment were published in The
Oregonian on July 11, 2021, and the
Seattle Times on July 9 through July 13,
2021. We did not receive any requests
for a public hearing. All substantive
information provided during the
comment period either has been
incorporated directly into this final rule
or is addressed below.
Public Comments
We received 10 public comments in
response to the proposed rule. We
reviewed all comments we received
during the public comment period for
substantive issues and new information
regarding the proposed rule. Eight
commenters provided substantive
comments or new information
concerning the proposed delisting for
golden paintbrush. Below, we provide a
summary of the substantive issues
raised in the public comments we
received; however, comments outside
the scope of the proposed rule, and
those without supporting information,
do not warrant an explicit response and,
thus, are not presented here. Identical or
similar comments have been
consolidated into responses based on
comment theme.
(1) Comment: We received multiple
comments from WDNR and others
stating that golden paintbrush has not
met all the recovery criteria specified in
the recovery plan.
Response: Recovery plans provide
roadmaps to species recovery but are
not required in order to achieve
recovery of a species, or to evaluate it
for delisting. In addition, recovery plans
are also nonbinding documents that rely
on voluntary participation from
landowners, land managers, and other
recovery partners. A determination of
whether a valid, extant species should
be delisted is made solely on the
question of whether it meets the Act’s
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
definitions of an ‘‘endangered species’’
or a ‘‘threatened species.’’ Recovery
criteria and objectives are developed
based on the information known at that
time, and much is learned about a
species between the time the recovery
plan is developed and the time we
reassess whether it meets the Act’s
definition of endangered or threatened.
Based on the best available information,
we have determined that golden
paintbrush no longer meets either of
these definitions.
(2) Comment: We received several
comments from WDNR and others
questioning the metric in recovery
criterion 1 to evaluate a stable
population, suggesting it was no longer
based on the best available science and
providing examples of populations that
have declined. A comment from WDNR
also presented updated information on
progress towards meeting this criterion
from 2018–2020.
Response: We updated this final rule
to reflect the most up-to-date progress
toward this criterion (see discussion
under Criterion 1 for Delisting, above).
As discussed earlier in this document,
that criterion states that to be deemed
stable, a population must maintain a 5year running average population size of
at least 1,000 individuals, where the
actual count never falls below 1,000
individuals in any year. The 2007 5-year
review recommended counting only
flowering individuals and incorporating
a stable or increasing population trend
as based on a zero or positive overall
trend over 5 years (Service 2007, p. 3).
While we did not officially amend or
make an addendum to the recovery
plan, we accepted that the most
practical way to determine population
abundance was to count flowering
plants. The recommendation to evaluate
populations based on stable or
increasing trends in abundance was not
formally incorporated into an amended
recovery plan. However, in addition to
evaluating progress toward the recovery
criteria, we also evaluated in the SBR
(Service 2019, entire) the resiliency,
redundancy, and representation across
the species’ range in relation to the
potential threats to the species. In the
SBR, we evaluated the current condition
of the species at sites using various
parameters, including the level of
management, site condition, threats
addressed, abundance, and site
protection status. We elicited the advice
of experts to evaluate sites based on
these parameters. Populations were also
separately evaluated in the SBR with a
site viability index that took into
account population stability and trend.
All of this information was considered
when evaluating and making our
PO 00000
Frm 00056
Fmt 4700
Sfmt 4700
determination as to whether delisting is
warranted.
Some populations that once
maintained higher levels of abundance
have declined, and that abundance can
vary markedly across populations and
annually within populations (Fertig
2021, p. 23). Despite this variability in
abundance, the species has sufficient
resiliency and redundancy across its
range to maintain viability. In the
current condition analysis of the SBR,
16 sites were ranked as high condition,
with 9 of these sites in Oregon and 7 in
Washington. This distribution of high
condition sites across the range of the
species contributes to the redundancy of
golden paintbrush. We developed a
post-delisting monitoring plan that will
help verify that golden paintbrush
remains secure into the future without
the protections of the Act.
(3) Comment: The WDNR stated
opposition to the proposed delisting
rule. Despite improvements in species
condition from the time of listing, the
WDNR stated that delisting was
premature based on concerns regarding
uncertainties related to golden
paintbrush’s long-term abundance and
viability. The WDNR and other
commenters expressed concern about
the funding available for continued
management and monitoring once
delisted.
Response: Our review of the best
available scientific and commercial data
indicates that the threats to the golden
paintbrush have been eliminated or
reduced to the point that the species no
longer meets the definition of an
endangered or threatened species under
the Act (see Determination of Golden
Paintbrush’s Status, below). Individual
sites may experience variability in
abundance, and while some have
declined, others have increased in
recent years (see Range, Distribution,
Abundance, and Trends of Golden
Paintbrush, above). Despite variability
in abundance, the successful
establishment of outplanted golden
paintbrush populations, primarily in
moderate to high condition, and mostly
in protected areas with management
help to increase the resiliency,
redundancy, and representation of the
species and contribute to its viability.
For more discussion of golden
paintbrush’s population trends and
viability, see Range, Distribution,
Abundance, and Trends of Golden
Paintbrush Summary of Biological
Status and Threats, and Recovery
Criteria, above.
Golden paintbrush is a managementdependent species, and even with
sufficient resources, populations can
decline due to various factors. Although
E:\FR\FM\19JYR1.SGM
19JYR1
ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
the majority of populations are under
conservation ownership that includes
management practices to preserve
essential characteristics of golden
paintbrush habitat, declines can still
occur. Conservation management will
continue in these habitats, but not
necessarily to the same degree at all
locations due to variations in capacity,
need, or constraints. As part of the
current condition analysis in the SBR,
the management level was assessed for
each site based on expert elicitation and
the best available information (see
Service 2019, pp. 40–44). This analysis
indicated that the majority of the sites
will receive, at minimum, maintenance
to preserve essential characteristics of
golden paintbrush habitat, with several
sites operating under long-term
management plans with committed
resources for management (see Service
2019, pp. 40–44). The number of and
distribution of populations established
across the range contributes to the
resiliency and redundancy of the
species, and its ability to maintain
sufficient viability despite some
variability in management. Management
will also continue to adapt over time to
address future challenges in
maintaining and restoring prairie
ecosystems. Funding for some
management activities will likely
decline post-delisting as some funding
sources are focused on the recovery of
listed species; however, the
commitments of our partners to golden
paintbrush conservation, as well as the
number of sites sharing similar habitat
and conservation objectives for other
prairie species of concern, will help
ensure continued management of the
species into the future. Additionally,
our post-delisting monitoring plan will
assess abundance as well as site
management and protection over a
minimum 5-year period after delisting.
Regarding continued monitoring by
WNHP, golden paintbrush is currently
State-listed as priority 2 in the
Washington State Natural Heritage Plan,
and State listing and prioritization is
ultimately at the discretion of the State.
Like many State-listed plant species and
other plant species of State concern, we
anticipate that the WDNR through its
WNHP and ODA will continue to
monitor golden paintbrush in
Washington and Oregon, respectively,
although monitoring efforts may not
occur as often as they have in the past.
(4) Comment: Several commenters
stated concern over the likelihood for
post-delisting management to continue
and be effective. Comments included
site-specific examples such as Forbes
Point, American Camp, Rocky Prairie,
and Glacial Heritage where decline in
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
golden paintbrush abundance due to
invasion by exotic grasses or other
unknown factors occurred despite
support or management for the species.
Response: As we describe above in
our response to Comment (3)
management will also continue to adapt
over time to address future challenges in
maintaining and restoring prairie
ecosystems and the PDM plan will
assess abundance as well as site
management and protection over a
minimum 5-year period after delisting.
Please see our response to Comment (3),
above, for a discussion of variation in
abundance and management for the
species and our response to Comment
(5), below, about declines in abundance
in some populations.
Regarding the site-specific examples
provided by commenters, the Forbes
Points and American Camp sites are in
low condition, the Rocky Prairie site is
in moderate condition and the Glacial
Heritage site is in high condition based
on our current condition analysis in the
SBR which considered management
level among other factors that can
impact site condition including habitat
condition, threats, abundance, and site
protection status (Service 2019, p. 54).
(5) Comment: We received comments
from WDNR and others providing
updated survey data from 2019 and
2020 for outplanted populations,
describing the variable survey effort and
an overall decline in abundance from
2018.
Response: WDNR and others provided
updated abundance information for
outplanted populations since 2018,
which we considered and incorporated
into this Final Rule (see Range,
Distribution, Abundance, and Trends of
Golden Paintbrush, above). As described
in their comments, outplanted
populations reached their highest peak
to date in 2018 at 562,726 flowering
plants and declined to 325,320 plants in
2019. In 2020, there was a reduction of
survey effort, and 25 populations in
Oregon were not surveyed due to
COVID restrictions. If 2019 data were
substituted for the 25 populations in
Oregon that were not surveyed in 2020,
it is assumed, based on extrapolation,
that the estimated 2020 rangewide
abundance would be greater than
370,000 plants (Fertig 2021, p. 22). Even
without the 25 sites that were not
monitored in 2020, the last 4 years of
monitoring (2017–2020) represent the 4
years with greatest abundance
rangewide. The year 2020 also
represents the second-highest
abundance of golden paintbrush in
Washington State at 202,208, which was
a 47.8 percent increase from 136,846 in
2019. Several new outplantings have
PO 00000
Frm 00057
Fmt 4700
Sfmt 4700
46103
been initiated since 2018, and we are
continuing to work with our partners to
plan new outplantings in Oregon and
Washington. Individual sites may
experience variability, and while some
have declined, others have increased in
recent years (Service 2019, pp. 27–29;
Fertig 2021, pp. 11–29). The species
appears to have sufficient resiliency and
redundancy across its range to maintain
sufficient viability, despite variability in
abundance.
(6) Comment: We received a comment
from WDNR and several other
commenters highlighting concerns over
population declines since 2012 in the
populations extant at the time of listing.
Response: At the time of listing in
1997, there were 10 known golden
paintbrush populations in Washington
and British Columbia, and the species
was considered extirpated from Oregon.
The SBR identified 48 populations
established across the range of the
species in 2018, including 26
populations established in Oregon
(Service 2019, p. 11). The ten
populations extant at the time of listing
make up a small proportion of the
current total abundance of this species
established across its range. While many
of the historical populations across the
range of the species were likely
extirpated due to land-use changes,
such as development and agriculture,
along with encroachment of trees and
other woody plants, the persistence of
these ten extant populations may be due
to their protected locations that are not
available for conversion for agriculture
or development. Studies suggest that
like other rare species, golden
paintbrush may have been eliminated
from the most suitable sites with the
remaining extant populations relegated
to marginal sites that did not provide
optimal habitat at the time of listing
(Falk et al. 1996, p. 472; Dunwiddie and
Martin 2016, p. 12). Sites with deeper
soils and more moisture availability,
along with a more diverse native plant
community are more likely to support
the species (Dunwiddie and Martin
2016, entire), and successful
reintroduction to prairies in former
agriculture lands with deeper soils have
had great success (Delvin 2013, p. 7).
Thirty-seven outplanted populations of
golden paintbrush have been
established and represent the majority
of the abundance of the species across
its historical range, including 26
populations in Oregon where the
species was previously extirpated.
These outplanted populations help to
increase the resiliency, redundancy, and
representation of the species and
contribute to its viability. While the 10
sites extant at the time of listing remain
E:\FR\FM\19JYR1.SGM
19JYR1
ddrumheller on DSK120RN23PROD with RULES1
46104
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
and continue to contribute to the
species’ recovery, these sites likely do
not represent the ideal site
characteristics for the species. Although
the 10 populations at the time of listing
have exhibited decline, the efforts at
outplanted sites across the range
represent the recovery of golden
paintbrush. For more information, see
the discussion above on populations
extant at the time of listing under
Range, Distribution, Abundance, and
Trends of Golden Paintbrush.
(7) Comment: We received several
comments addressing the difficulties of
establishing new populations, and
highlighting the variability in seeding
success, even on sites with established
populations.
Response: We identified the
difficulties in establishing new
populations and the variability in
seeding success in the SBR for golden
paintbrush (Service 2019, p. 51) and
took this into account in our
determination. It is not uncommon to
have failed reintroduction or
introduction attempts for any species.
For golden paintbrush, despite some
outplanting failures, outplanted
populations have been largely
successful and represent the majority of
the abundance of golden paintbrush
across the range. Furthermore, in
Oregon, where the species was
previously extirpated, 26 populations
have been established due to
outplanting. Golden paintbrush
continues to be outplanted by our
partners at other conservation sites with
the expectation of establishing even
more populations across the species’
range in the future.
(8) Comment: The WDNR and several
other commenters disagreed that direct
seeded populations may initially
undergo a period of rapid growth
followed by a period of decline to a
more stabilized number. The
commenters stated that it is unknown if
population stabilization will occur.
Response: While there may be an
initial period of rapid growth following
an establishment period, population
trends following a peak appear to vary
greatly by site (Fertig 2021 pp. 24–27).
After some large declines, several sites
rangewide increased from 2019 to 2020,
although not to the level of the initial
spike in abundance. While some
populations show a boom-bust
population trend as was documented at
some outplanted sites in Oregon (Kaye
2019, pp. 26–27), not all populations
across the range are experiencing
consistent decline. Rangewide
abundance from 2017–2020 represent
the four greatest abundances across all
of the years monitored, including 25

sites that were not monitored in Oregon
in 2020 (Fertig 2021, p. 22). As some
commenters mentioned, the addition of
seed to some of these populations
complicates the assessment of
population trends over time.
Furthermore, population variability
seen following the initial peak could be
attributed to other impacts to the
species from other stressors such as
drought, herbivory, or competition from
invasive species at the site level. Taken
together, we find that the available
information supports that while golden
paintbrush populations may peak in
abundance following initial
establishment and may decline to lower
levels, the pattern does not suggest a
species-level decline overall rangewide.
We will continue to monitor
populations over 5 years using the postdelisting monitoring plan, which will
contribute data and increase our
understanding of population dynamics
and persistence over those years.
(9) Comment: The WDNR commented
that there was no mention of the
viability index developed by Dr. Tom
Kaye for golden paintbrush in the
proposed rule. In addition to providing
us with 2019 and 2020 golden
paintbrush survey data and their
updated viability index for the species,
the WDNR stated that as of 2020, 9 of
52 populations had a viability index
score of 3, indicative of populations
with positive growth over time,
relatively stable numbers, and greater
than 1,000 flowering individuals
averaged over 5 years.
Response: The Service considered the
viability index developed by Dr. Tom
Kaye and summarized this information
in the SBR which provides the best
available information to inform our
listing decision under the Act. In
addition, in response to the information
submitted by the WDNR, we recalculated the viability index with data
that include the most-recent survey year
(either 2019 or 2020), since many sites
were not surveyed in 2020. This
resulted in 10 out of 46 populations
having a score of three, an increase from
the 6 out of 43 populations with a score
of 3 identified in the SBR, indicating
there are now more populations with
high viability than what we identified in
2018. As we mentioned in the SBR,
indices of this type are useful for
synthesizing several pieces of
information, but they can simplify or
oversimplify available information. This
index was intended to provide a broad
evaluation of the species’ population
size and stability, and while these data
were taken into consideration, they
were considered along with the current
condition analysis in the SBR.

Additionally, we used updated survey
data to evaluate the status relative to the
recovery criteria (see Recovery Criteria,
above).
(10) Comment: We received several
comments (from WDNR and others)
expressing concern over potential
impacts of climate change on the
species. We also received several
comments from WDNR and others
highlighting WDNR’s 2019 report
updating an earlier climate change
vulnerability assessment of golden
paintbrush.
Response: In this final rule, we have
incorporated the new information from
the climate change vulnerability
assessment (Kleinknecht et al. 2019,
entire) and have added to our
discussion on climate change. The
Service reviews the best scientific and
commercial information available when
conducting a threats analysis. In
considering what factors might
constitute a threat, we look beyond the
mere exposure of the species to the
factor to determine whether the
exposure causes actual impacts to the
species. The mere identification of
factors that could impact a species
negatively is not sufficient to compel a
finding that listing (or maintaining a
currently listed species) on the Federal
Lists of Endangered or Threatened
Wildlife and Plants is appropriate. In
determining whether a species meets
the definition of a threatened or
endangered species, we must evaluate
all identified threats by considering the
species’ expected response and the
effects of the threats—in light of those
actions and conditions that will
ameliorate the threats—on an
individual, population, and species
level, as well as the cumulative effect of
the threats.
Drought, particularly in the spring
and summer, likely impacts golden
paintbrush populations, with
potentially larger impacts on
populations with low viability. Research
conducted on microsite needs for the
species suggested that deeper soils with
high richness of native perennial forbs
were more likely to support the species
(Dunwiddie and Martin 2016, entire).
Establishing populations can be
difficult, particularly with annual
variability in climate and drought seen
in recent years, and as a result, multiple
outplantings have failed. Despite this,
seven new outplantings have been
initiated since 2018 in Washington,
including one on Protection Island.
While it is difficult to assess the success
of these outplantings due to variable
monitoring efforts in recent years, two
have been noted as likely unsuccessful
due to presence of nonnative weedy

annuals, but the others show promise
(Martin 2021, pp. 10, 23–25).
On a rangewide scale, the species
demonstrates sufficient resiliency and
representation to adapt to projected
changes in climate. We have established
17 populations with a 5-year average of
greater than 1,000 individuals over the
species’ range from British Columbia to
Oregon, on sites representing
environmental diversity consisting of
wet and dry prairie, and valley foothills
(Kaye 2019, p. 10). Total abundance was
greater than 325,320 flowering plants
across the range in 2019, and 288,699 in
2020 (excluding 25 populations that
were not surveyed due to COVID
restrictions); substituting 2019 data for
populations not surveyed in 2020 yields
an estimated abundance of greater than
370,000 flowering plants rangewide
(Fertig 2021, p. 22). Despite drought
seen in recent years, abundance of
populations extant at the time of listing
increased in 2020, and Washington
populations reached their secondhighest total abundance of 202,208
flowering plants, a 47.8 percent increase
from 2019 (Fertig 2021, p. 11). Despite
evidence of the potential effects of
drought on golden paintbrush
abundance in recent years (see Fertig
2021, p. 30; Martin 2021, p. 6), periods
of drought have not been documented to
consistently impact abundance across
populations.
Regional climate change literature
suggests that prairie ecosystems were
established under warmer and drier
conditions and are unlikely to be
disadvantaged from future increased
summer drought (Bachelet et al. 2011, p.
417). Golden paintbrush populations
can experience high variability in
abundance between years (Fertig 2021,
pp. 24–27), and while climate change is
a stressor, given the species’ high
abundance and distribution across the
range from British Columbia to Oregon,
golden paintbrush should have
sufficient resiliency and redundancy to
remain viable into the future.
Establishing plant species such as the
golden paintbrush to populate the full
geographic and climatic range of Pacific
Northwest prairies has been identified
as a ‘‘climate-smart’’ strategy (Bachelet
et al. 2011, p. 420). The post-delisting
monitoring plan will facilitate the
evaluation of the species beyond
delisting and detect unanticipated levels
and/or extent of declines in abundance.
Since the publication of the proposed
rule (86 FR 34695; June 30, 2021), we
received an updated climate change
vulnerability index (CCVI) report from
our State partners at the WDNR’s
Washington Natural Heritage Program
(Kleinknecht et al. 2019, entire). This
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
report was provided as a comment from
WDNR. We evaluated the report and
compared it to a similar assessment that
was conducted in 2014 (Gamon 2014,
entire). The CCVI was conducted using
a NatureServe protocol, which relies on
a species’ natural history, distribution,
and landscape to inform whether and to
what degree it will be impacted by
climate change (Young et al. 2016,
entire). In the 2019 report, golden
paintbrush was ranked as ‘‘Highly
Vulnerable’’ to climate change, a change
from the 2014 report which ranked it as
‘‘Presumed Stable’’ (Kleinknecht et al.
2019, entire; Gamon 2014, entire).
While this 2019 CCVI report has
helped inform our decision, it does not
change our final determination. The
2019 assessment looked only at a small
proportion of the species’ range. It
assessed only a subset of sites from
Washington, based on 22 native
occurrences (11 extant and 11 extirpated
or historical), not including the 10
outplanted sites in Washington or any of
the populations in Oregon. The
distribution of points used in the
assessment were primarily in North
Puget Sound, and given that half of
these represent sites that have already
undergone extirpation, this report is not
necessarily representative of the
potential impact on golden paintbrush
across its currently occupied range.
Additionally, the guidelines for the
CCVI describe that it works best for the
scale from the size of a National Park to
a State, and at larger scales may mask
the vulnerability of local populations to
climate change (Young et al. 2016, p. 9).
Based on the larger scale of golden
paintbrush’s range, from Oregon to
British Columbia, the CCVI method is
not likely to be appropriate to assess
climate change vulnerability.
(11) Comment: We received a
comment from WDNR and several
others expressing concern about the
impacts of herbivory on golden
paintbrush’s viability. Commenters
provided examples of impacts at
specific sites, the difficulties in
managing herbivory, and the potential
impacts to seed production.
Response: Herbivory was noted as a
threat at the time of listing in 1997,
especially due to the limited number
(10) of extant populations. Despite
having a potential impact on
abundance, a total of 48 golden
paintbrush populations are now
represented across the species’ range in
a variety of habitats and constitute a
large geographic distribution
contributing to the species’ resiliency
and redundancy, and to the species’
ability to withstand stochastic events,
including herbivory. Active, targeted

management may be important in
curtailing significant impacts, but it is
not likely to occur across all sites at the
same level, and it is not intended to
result in the complete elimination of
herbivory impacts on this species.
Despite the recent examples of
herbivory provided in the comments
and anecdotal observations for specific
sites and years, there are no consistent
data linking herbivory to population
declines, especially at the rangewide
scale. Herbivory can vary by site, year,
frequency, and level of impacts.
Populations of the species will likely
retain moderate to high levels of
viability given the species’ established
redundancy across its range and the
suitable condition of the habitat despite
variable herbivory impacts; however,
the post-delisting monitoring plan is
designed to help track site-specific
management and potential impacts to
species abundance for at least 5 years
following delisting. For more
information, please see the discussion of
herbivory under Summary of Biological
Status and Threats, above.
(12) Comment: We received a
comment from WDNR and others
expressing concern over potential
impacts of hybridization to golden
paintbrush, as well as expressing
concern that the hybridization strategy
and guidance document was not
available for review during the June 30,
2021, proposed rule’s public comment
period.
Response: Hybridization is a potential
threat to golden paintbrush that must
continue to be managed, and we
continue to work collaboratively with
our partners to find solutions and
management for sites that are already
impacted by hybridization. Although a
public commenter noted two sites on
Whidbey Island as having potential
hybridization impacts given a previous
experimental study that seeded both
paintbrush species, given low
recruitment of harsh paintbrush at these
sites, hybridization has never been
identified by experts as a concern in
those sites.
While the details of the hybridization
strategy and guidance were not available
during the June 30, 2021, proposed
rule’s public comment period, when the
document was finalized, we organized a
public roll-out where we presented
details of the hybridization strategy and
guidance, answered questions, and
highlighted to our conservation partners
that comments would be accepted to
inform the next iteration of the
document to make further
improvements to the strategy. The
document was posted on our website,
and no comments were received.

Solutions presented in the hybridization
strategy and guidance document
include, but are not limited to,
preventing hybridization in other
geographic areas, implementing a
decision-making framework for new
sites under consideration for paintbrush
plantings, actively managing sites that
are hybridized, and mapping the
distribution of both golden and harsh
paintbrush. Through the MOU and
hybridization strategy and guidance
document, we and our State agency
partners are committed to managing
hybridization and working
collaboratively with our other prairie
conservation partners to ensure this
potential threat is adequately managed
after the delisting of golden paintbrush.
(13) Comment: We received a
comment from WDNR and several
others noting the lack of seed
production at some populations in
recent years (2019–2021), emphasizing
the potential for declines given the
species’ short-lived seed bank and the
species’ reliance on bumble bees for
pollination.
Response: Although we agree with the
need to track and better understand the
magnitude and extent of possible
impacts of reduced seed production,
based on the best available information,
the observed reduced seed production at
some sites does not appear to be
resulting in notable demographic
changes impacting the resiliency of
golden paintbrush populations. Any
decline in seed production could
negatively impact a golden paintbrush
population given its short-lived
seedbank, and there are many
unknowns associated with the potential
effects of climate change on both golden
paintbrush and pollinator communities.
To date, however, there are
uncertainties regarding the frequency,
distribution, and scale of the lack of
seed production, and uncertainty
whether these represent short-term,
isolated events or a large-scale change.
Likewise, while golden paintbrush is
reliant on bumble bees as its primary
pollinator, it is unknown if pollinator
decline is occurring across the range of
golden paintbrush. Two bumble bees
identified at the species level in the
SBR, Bombus vosnesenskii and B.
bifarius, were assessed as stable in the
Pacific Northwest, and one bumble bee,
B. californicus (sometimes recognized as
B. fervidus), is less common in the
Pacific Northwest than historically
(Hatfield et al. 2021, pp. 15, 32, 72–73).
However, the status and trends of these
and other pollinators have not been
evaluated in golden paintbrush
populations. These anecdotal
observations present important
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
information, yet it remains unclear how
they translate to trends in population
abundance over time and the scope of
the impact across the species’ range. We
do not have information to conclude
that these concerns are impacting the
species to a degree that would result in
the species meeting the Act’s definition
of either an endangered species or a
threatened species. Post-delisting
monitoring will enable us to monitor
population abundance for at least 5
years after the species has been delisted.
(14) Comment: We received a
comment from WDNR and several
others expressing concern over the
number of small populations (fewer
than 100 individuals) and the small size
of habitat occupied by golden
paintbrush at some sites (less than 1
acre), suggesting that small populations
and small patches of habitat should be
eliminated from consideration regarding
contribution towards recovery.
Response: We describe in the SBR
that larger sites are likely better for
population viability, as they allow for
the development of larger populations
and greater genetic diversity (Service
2019, pp. 35–36); however, there is no
basis to remove populations existing on
less than 1 acre or those with abundance
of fewer than 100 individuals from our
assessment of sites contributing to
recovery. While small populations may
inherently have a greater relative risk of
extirpation than larger populations, that
does not mean they cannot or do not
contribute to species recovery. Site
abundance is an important
consideration with regard to the
potential for the species to persist over
time, and we used site abundance as
part of our analysis of current condition
in the SBR (Service 2019, p. 27). These
data were incorporated into a
population viability index as well as an
assessment of current condition, which
were both considered when evaluating
whether the species needs protections
under the Act. Habitat patch size was
discussed in the SBR (Service 2019, pp.
35–38), and as noted, there are
uncertainties regarding the importance
of habitat patch size for populations of
golden paintbrush. The number of sites
with more than 1,000 individuals and
the wide distribution across the species’
historical range will likely provide
sufficient resiliency and redundancy to
protect the species from stochastic
events.
(15) Comment: We received multiple
comments disagreeing with our
evaluation of progress toward recovery
criterion 2 and our assessment of the
level of protection based on land
ownership.
PO 00000
Frm 00060
Fmt 4700
Sfmt 4700
Response: In this final rule, we note
that this criterion was not precisely met
as stated in the recovery plan (see
Criterion 2 for Delisting, above).
However, a significantly greater number
of populations under conservationfocused ownership provide protection
to either the species or its habitat
compared to the minimum number
identified in the criterion; this will help
the species retain sufficient viability
into the future. Forty-five of the 48
golden paintbrush populations are in
either public ownership; are owned by
a conservation-oriented,
nongovernmental organization; or are
under conservation easement (Service
2019, p. 62). This number is much
higher than the number (15) required to
provide protection in the recovery
plan’s criterion 2. Such ownership is
expected to protect sites from
development and land use that would
have long-term, wide-ranging
deleterious effects on this species.
Prairies are management-dependent
habitats, and while habitat management
will likely continue to occur across the
majority of the sites, it will not
necessarily occur to the same degree
due to variations in capacity, need, or
constraints across sites. We have
developed a post-delisting monitoring
plan to monitor abundance, site
management, and the protection status
of populations over at least 5 years
following delisting.
(16) Comment: We received multiple
comments expressing concern regarding
the potential of recovery sites being
shared between golden paintbrush and
Taylor’s checkerspot butterfly, given the
threat of hybridization between golden
paintbrush and harsh paintbrush, the
latter a common host plant for Taylor’s
checkerspot butterfly.
Response: Sites that support Taylor’s
checkerspot butterfly with harsh
paintbrush will not be available to
support golden paintbrush. However,
there may be opportunities for Taylor’s
checkerspot butterfly and golden
paintbrush to share sites, particularly if
other hosts plants (in addition to golden
paintbrush) are used, including English
plantain (Plantago lanceolata).
Likewise, sites in Oregon that have
golden paintbrush and other host plants
do support populations of Taylor’s
checkerspot butterfly. In this final rule,
we address the fact that hybridization
with harsh paintbrush has led to the
abandonment of three recovery sites for
golden paintbrush. Hybridization is a
serious potential threat, and we have
entered into an MOU concerning
hybridization with our State partners
(WDFW and WDNR) and created a
hybridization strategy and guidance
E:\FR\FM\19JYR1.SGM
19JYR1
ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
document to ensure the threat of
hybridization with harsh paintbrush is
managed and coordinated between
partners into the future.
(17) Comment: We received several
comments providing information on
recent difficulties with seed availability
at some sites, the potential impacts to
nursery seed production, and challenges
with seed production.
Response: These observations are
concerning given the short-lived
seedbank of the species; however, it
remains unclear if the local, episodic
events (due to herbivory or drought)
represent a new long-term scenario with
consistent impacts across the range of
the species. Our post-delisting
monitoring plan will direct efforts to
track populations to help determine if
these observations continue and
whether or not there are broader
impacts to golden paintbrush.
If populations of golden paintbrush
decline below a certain threshold, seed
collection from certain sites could prove
difficult or inadvisable, and seed
production for this species could be
affected. Seed production efforts might
need to be supplemented by some
outplanted populations that originated
from the populations extant at the time
of listing and could incorporate
increased genetic diversity into nursery
production (St. Clair et al. 2020, pp.
587–590). While a comment highlighted
past difficulties in seed production for
the species at a seed farm in
Washington, seed production efforts
across the range have been sufficient to
support numerous outplantings that
have contributed to the recovery of the
species across its range. Currently, there
are seed production programs at the
Center for Natural Lands Management,
along with smaller scale operations in
North Puget Sound representing seed
collected from the populations extant at
the time of listing on Whidbey Island,
the San Juan Islands, and South Puget
Sound. New mixed-source beds for
golden paintbrush have been recently
established at the Center for Natural
Lands Management and the Pacific Rim
Institute, and we will continue to work
with our partners to ensure that seed
sources for this species remain available
as long as considered necessary. These
combined seed production efforts will
continue to support ongoing
establishment of new populations and
augmentation of existing populations
throughout the range of the species.
(18) Comment: We received a few
comments describing historical habitat
loss of Pacific Northwest prairies. We
also received a comment discussing the
importance of these rare habitats to
VerDate Sep<11>2014
16:28 Jul 18, 2023
Jkt 259001
Tribes from a public commenter
unaffiliated with any Tribe.
Response: The rarity of prairies on the
landscape presents challenges to
conservation of prairie-dependent
species, including golden paintbrush.
Pacific Northwest prairies have
experienced significant declines from
their historical distribution due to
habitat loss from development and
agriculture, as well as changes in
disturbance regimes and the
maintenance provided by indigenous
Tribes for thousands of years. While
these comments were not submitted by
a Tribe, we know the success of prairiedependent species conservation is tied
directly to the habitats that support the
species and to the extensive network of
partners, including Tribes, working to
restore and maintain prairies across the
species’ range;. These partnerships will
continue to focus on restoration and
maintenance of golden paintbrush and
other species that rely on these rare
prairie communities into the future. For
more information, please see the
discussion of habitat loss under
Summary of Biological Status and
Threats, above.
(19) Comment: We received a
comment that disagrees with the
information presented on genetic
diversity in the June 30, 2021, proposed
rule, stating that golden paintbrush has
reduced genetic diversity because seed
used to establish populations was
sourced from seed from the populations
extant at the time of listing.
Response: Genetic studies have
indicated that despite its limited
geographic range and isolation of its
populations, golden paintbrush has high
levels of diversity (Godt et al. 2005, p.
87; Lawrence and Kaye 2011, p. 173).
Additionally, a recent study indicates
that genetic diversity has increased in
reintroduced populations relative to
extant populations as a result of
multiple source populations propagated
together in a nursery production setting
(St. Clair et al. 2020, pp. 589–591).
Establishing populations across the
species’ range and in a variety of
ecological settings will further
contribute to the genetic diversity and
representation of the species.
(20) Comment: We received a
comment disagreeing with the
established methodology of counting
flowering plants to determine
abundance estimates, The commenter
stated that survey information could be
unreliable due to the lack of nonflowering plant information.
Response: We developed the
abundance estimate methodology in
coordination with the golden paintbrush
technical team to provide a consistent
PO 00000
Frm 00061
Fmt 4700
Sfmt 4700
46107
and reliable measure of adult plant
abundance within populations to track
population status (Service 2007, p. 3).
We and the technical team determined
it was impractical to count nonflowering golden paintbrush plants, and
recommended modifying Recovery
Criterion 1 to specify a flowering plant
metric (Service 2007, p. 3). Although
counting flowering plants could mean
that populations might actually be
undercounted, because vegetative plants
are not counted, flowering plant
abundance better informs the number of
individuals most likely to
reproductively contribute to the
population, and may also be the best
method to estimate a reasonable
minimum population size.
(21) Comment: We received multiple
comments highlighting potential
impacts on the golden paintbrush and
its habitat from invasive plant species
given projected warmer temperatures.
Response: Habitat loss has been
considered a threat to the species since
the time of listing (1997), and part of
that consideration is focused on
invasive species. While invasive species
will always be a potential threat that
will need adequate management, given
the ongoing invasive species
management commitments across the
species’ range, golden paintbrush is
expected to maintain moderate to high
viability. Many of the exotic species in
the Pacific Northwest have wide
distributions and are likely adaptable to
climate change (Bachelet et al. 2011, p.
417). As commenters mentioned, there
are ongoing studies focused on how to
manage Vulpia ssp. (a winter annual
grass) in South Puget Sound prairie
communities that will provide valuable
information on how to control this
nonnative species within golden
paintbrush habitat across its range.
Management techniques are constantly
evolving as new challenges arise from
invasive species, climate change, and
unforeseen circumstances. This
progression in management will likely
continue into the future; however, the
level of success is not always certain.
We developed a post-delisting
monitoring plan to track population
status, site-specific management actions,
and the presence of invasive species
that will continue for at least 5 years
following delisting.
(22) Comment: We received multiple
comments expressing concern over the
adequacy of the post-delisting
monitoring plan to track the species’
condition over the 5-year timeframe.
The commenters suggest that estimating
population size into categories (more
than 1,000 flowering plants and more
than 10,000 flowering plants) would be
E:\FR\FM\19JYR1.SGM

46108
Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations
ddrumheller on DSK120RN23PROD with RULES1
inadequate to detect changes in size and
population trend and reduces the ability
to understand why changes are
occurring.
Response: The population size
categories referenced in the postdelisting monitoring plan are not meant
to be a population target but rather a
threshold at which to review
significance, methods, and potential
threats with States and other
collaborators before numbers might fall
below the recovery objective. These
thresholds are also consistent with those
used in the SBR current condition
analysis. Following delisting, the Act
requires us to monitor effectively for not
less than 5 years the status of the
species in cooperation with the States
that are within the range of the species
(16 U.S.C. 1533(g)(1)). We developed a
draft post-delisting monitoring plan for
the golden paintbrush, coordinated
review of the plan with State agencies
in Washington and Oregon, and made
the draft plan available for public
review and comment. Sustaining postdelisting monitoring efforts can be
challenging and subject to competing
priorities for available resources.
Nonetheless, we designed the postdelisting monitoring assuming limited
resources. We are coordinating with
State agencies in Washington and
Oregon to find funding to support postdelisting monitoring efforts, but we fully
anticipate some of the conservation
landowners will continue to monitor
populations on their own because of
their ongoing interest in and
commitment to conserving this species
and others. We will continue to work
with our conservation partners to ensure
implementation of an effective and
feasible post-delisting monitoring plan
for the golden paintbrush.
Determination of Golden Paintbrush’s
Status

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 an
endangered species or a threatened
species because of any of the following
factors: (A) The present or threatened
destruction, modification, or
VerDate Sep<11>2014

curtailment of its habitat or range; (B)
overutilization for commercial,
recreational, scientific, or educational
purposes; (C) disease or predation; (D)
the inadequacy of existing regulatory
mechanisms; or (E) other natural or
manmade factors affecting its continued
existence.
Status Throughout All of Its Range
After evaluating threats to the species
and assessing the cumulative effect of
the threats under the Act’s section
4(a)(1) factors, we find, based on the
best available information, and as
described in our analysis above,
stressors identified at the time of listing
and several additional potential
stressors analyzed for this assessment
do not affect golden paintbrush to a
degree that causes it to be in danger of
extinction either now or in the
foreseeable future. Development of
property for commercial, residential,
and agricultural use (Factor A) has not
occurred to the extent anticipated at the
time of listing and is adequately
managed; existing information indicates
this condition is unlikely to change in
the foreseeable future. Potential
constriction of habitat for expansion and
refugia (Factor A) also has not occurred
to the extent anticipated at the time of
listing, and existing information
indicates this condition is unlikely to
change in the foreseeable future. Habitat
modification through succession of
prairie and grassland habitats to shrub
and forest lands (Factor A) is adequately
managed, and existing information
indicates this condition is unlikely to
change in the foreseeable future.
Recreational picking and associated
trampling (Factor B) has not occurred to
the extent anticipated at the time of
listing; the species appears to tolerate
current levels of this activity, and
existing information indicates that this
condition is unlikely to change in the
foreseeable future. Herbivory on plants
and seeds (Factor C) has not occurred to
the extent anticipated at the time of
listing; the species appears to tolerate
current levels of herbivory, and existing
information indicates that this condition
is unlikely to change in the foreseeable
future. Hybridization with the harsh
paintbrush (Factor E) is adequately
managed, and existing information
indicates this condition is unlikely to
change in the foreseeable future.
Finally, golden paintbrush appears to
adequately tolerate the effects of climate
change (Factor E), and existing
information indicates that this tolerance
is unlikely to substantially change in the
foreseeable future. In addition, there are
means to help further mitigate for those
effects of climate change (e.g., continued
PO 00000
Frm 00062
Fmt 4700
Sfmt 4700
outplanting across varied site
conditions). The existing regulatory
mechanisms (Factor D) are sufficient to
ensure protection of the species at the
reduced levels of threat that remain.
Thus, after assessing the best available
information, we determine that golden
paintbrush is not in danger of
extinction, nor likely to become so in
the foreseeable future, throughout all of
its range.
Status Throughout a Significant Portion
of Its Range
Under the Act and our implementing
regulations, a species may warrant
listing if it is in danger of extinction or
likely to become so in the foreseeable
future throughout all or a significant
portion of its range. Having determined
that the golden paintbrush 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 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
golden paintbrush, we choose to
evaluate the status question first. We
began by identifying portions of the
range where the biological status of the
species may be different from its
biological status elsewhere in its range.
For this purpose, we considered
information pertaining to the geographic
distribution of (a) individuals of the
species, (b) the threats that the species
faces, and (c) the resiliency condition of
populations.
For the golden paintbrush, we
considered whether the threats or their
effects on the species are greater in any
biologically meaningful portion of the
species’ range such that the species is in
danger of extinction now or likely to
become so in the foreseeable future in
that portion. We examined the following
threats: (1) Habitat succession of prairie
and grassland habitats to shrub and
forest due to fire suppression,
interspecific competition, and invasive
species; (2) development of property for

ddrumheller on DSK120RN23PROD with RULES1
commercial, residential, and
agricultural use; (3) low potential for
expansion and refugia due to
constriction of habitat by surrounding
development or land use; (4)
recreational picking (including
associated trampling); (5) herbivory (on
plants and seeds); (6) hybridization with
harsh paintbrush; and (7) the effects of
climate change, including cumulative
effects. Although the impact of
hybridization with the harsh paintbrush
is most evident in the South Puget
Sound region of the species’ range, this
impact was due to the unintended
consequences of seeding harsh
paintbrush in aid of another species, so
as a potential stressor, it is being
addressed throughout the species’ range
with the hybridization strategy and
guidance. We found no biologically
meaningful portion of the golden
paintbrush’ range where threats are
impacting individuals differently from
how they are affecting the species
elsewhere in its range, or where the
condition of the species differs from its
condition elsewhere in its range such
that the status of the species in that
portion differs from its status in any
other portion of the species’ range.
Therefore, we find that the species is
not in danger of extinction now or likely
to become so in the foreseeable future in
any significant portion of its range. This
does not conflict with the courts’
holdings in Desert Survivors v.
Department of the Interior, 336 F. Supp.
3d 1131 (N.D. Cal. 2018), and Center for
Biological Diversity v. Jewell, 248 F.
Supp. 3d. 946, 959 (D. Ariz. 2017)
because, in reaching this conclusion, we
did not apply the aspects of the Final
Policy on Interpretation of the Phrase
‘‘Significant Portion of Its Range’’ in the
Endangered Species Act’s Definitions of
‘‘Endangered Species’’ and ‘‘Threatened
Species’’ (79 FR 37578; July 1, 2014),
including the definition of ‘‘significant’’
that those court decisions held to be
invalid.
Determination of Status
Our review of the best available
scientific and commercial information
indicates that the golden paintbrush
does not meet the definition of an
endangered species or a threatened
species in accordance with sections 3(6)
and 3(20) of the Act. Therefore, we
remove the golden paintbrush from the
List of Endangered and Threatened
Plants.
Effects of the Rule
This final rule revises 50 CFR 17.12(h)
by removing the golden paintbrush from
the List of Endangered and Threatened
Plants. On the effective date of this rule
VerDate Sep<11>2014

(see DATES, above), the prohibitions and
conservation measures provided by the
Act, particularly through sections 7 and
9, no longer apply to the golden
paintbrush. Federal agencies will not be
required to consult with the Service
under section 7 of the Act in the event
that activities they authorize, fund, or
carry out may affect the golden
paintbrush. There is no critical habitat
designated for this species, so there is
no effect to 50 CFR 17.96.
10,000 flowering individuals as opposed
to an actual count or calculated estimate
of flowering plants. This modification
should streamline monitoring efforts. It
is our intent to work with our partners
to maintain the recovered status of
golden paintbrush. The final PDM plan
can be found at https://
www.regulations.gov under Docket No.
FWS–R1–ES–2020–0060.
Post-Delisting Monitoring
Section 4(g)(1) of the Act requires us,
in cooperation with the States, to
implement a system to monitor
effectively, for not less than 5 years, all
species that have been recovered and
delisted. Post-delisting monitoring
(PDM) refers to activities undertaken to
verify that a species delisted due to
recovery remains secure from the risk of
extinction after the protections of the
Act no longer apply. The primary goal
of PDM is to monitor the species to
ensure that its status does not
deteriorate, and if a decline is detected,
to take measures to halt the decline so
that proposing it as endangered or
threatened again is not needed. The
monitoring is designed to detect the
failure of any delisted species to sustain
itself without the protective measures
provided by the Act. If, at any time
during the monitoring period, data
indicate that the protective status under
the Act should be reinstated, we can
initiate listing procedures, including, if
appropriate, emergency listing under
section 4(b)(7) of the Act. Section 4(g) of
the Act explicitly requires us to
cooperate with the States in
development and implementation of
post-delisting monitoring programs, but
we remain responsible for compliance
with section 4(g) and, therefore, must
remain actively engaged in all phases of
post-delisting monitoring. We also seek
active participation of other entities that
are expected to assume responsibilities
for the species’ conservation postdelisting.
We prepared a PDM plan that
describes the methods for monitoring
the species after its delisting.
Monitoring of flowering plants at each
golden paintbrush site extant in 2018
will take place every other year, over a
minimum of 5 years, beginning the first
spring after the effective date of this
final delisting rule (see DATES, above).
Monitoring efforts will be slightly
modified from prior protocols, by only
requiring a visual estimation of
population size when the population
clearly exceeds 1,000 flowering
individuals but is fewer than 10,000, or
when a population clearly exceeds

Required Determinations
It is our position that, outside the
jurisdiction of the U.S. Court of Appeals
for the Tenth Circuit, environmental
analyses pursuant to the National
Environmental Policy Act of 1969
(NEPA; 42 U.S.C. 4321 et seq.) need not
be prepared in connection with
determining a species’ listing status
under the Endangered Species 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

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
acknowledge our responsibility to
communicate meaningfully with
recognized Federal Tribes on a
government-to-government basis. In
accordance with Secretary’s Order 3206
of June 5, 1997 (American Indian Tribal
Rights, Federal-Tribal Trust
Responsibilities, and the Endangered
Species Act), we 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 Native American
culture, and to make information
available to Tribes.
We do not believe that any Tribes will
be affected by this rule, and we did not
receive any comments on our June 30,
2021, proposed rule from a Tribe. There
are currently no golden paintbrush sites
on Tribal lands, although some sites
may lie within the usual and
accustomed places for Tribal collection
and gathering of resources.

NMFS closed directed fishing for POP
in the Bering Sea subarea of the BSAI
under § 679.20(d)(1)(iii) (88 FR 14926,
March 10, 2023) and as corrected (88 FR
18258, March 28, 2023).
NMFS has determined that
approximately 4,500 metric tons of POP
remain in the directed fishing
allowance. Therefore, in accordance
with § 679.25(a)(1)(i), (a)(2)(i)(C), and
(a)(2)(iii)(D), and to fully utilize the
2023 total allowable catch of POP in the
Bering Sea subarea of the BSAI, NMFS
is terminating the previous closure and
is opening directed fishing for POP in

1200 hrs, A.l.t., July 15, 2023, through
2400 hrs, A.l.t., December 31, 2023. This
will enhance the socioeconomic wellbeing of harvesters dependent on POP
in this area.
The Administrator, Alaska Region
considered the following factors in
reaching this decision: (1) the current
catch of POP in the BSAI and, (2) the
harvest capacity and stated intent on
future harvesting patterns of vessels
participating in this fishery.
Classification
NMFS issues this action pursuant to

Pursuant to 5 U.S.C. 553(b)(B), there
is good cause to waive prior notice and
an opportunity for public comment on
this action, as notice and comment
would be impracticable and contrary to
the public interest, as it would prevent
NMFS from responding to the most
recent fisheries data in a timely fashion
and would delay the opening of directed
fishing for POP in the Bering Sea
subarea of the BSAI. NMFS was unable
to publish a notification providing time
for public comment because the most
recent, relevant data only became

The Assistant Administrator for
Fisheries, NOAA also finds good cause
to waive the 30-day delay in the
effective date of this action under 5
U.S.C. 553(d)(3). This finding is based
upon the reasons provided above for
waiver of prior notice and opportunity
for public comment.
Without this inseason adjustment,
NMFS could not allow the fishery for

Endangered and Threatened Wildlife and Plants; Removing Golden
Paintbrush From the Federal List of Endangered and Threatened Plants
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), remove the
golden paintbrush (Castilleja levisecta) from the Federal List of
Endangered and Threatened Plants as it no longer meets the definition
of an endangered or threatened species under the Endangered Species Act
of 1973, as amended (Act). The golden paintbrush is a flowering plant
native to southwestern British Columbia, western Washington, and
western Oregon. Our review of the best available scientific and
commercial data indicates threats to the golden paintbrush have been
eliminated or reduced to the point that the species no longer meets the
definition of an endangered or threatened species under the Act.
DATES: This rule is effective August 18, 2023.

SUPPLEMENTARY INFORMATION:
Executive Summary
Why we need to publish a rule. Under the Act, if we determine a
plant species no longer meets the definition of an endangered or
threatened species, we remove it from the Federal List of Endangered
and Threatened Plants (i.e., we ``delist'' it). Delisting a species can
be completed only by issuing a rule through the Administrative
Procedure Act rulemaking process.
What this document does. This rule removes (delists) the golden
paintbrush from the Federal List of Endangered and Threatened Plants
because it no longer meets the Act's definition of either a threatened
species or an endangered species.
The basis for our action. Under the Act, we may determine that a
species is an endangered or threatened species because of any of the
following 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. The determination to delist a
species must be based on an analysis of the same factors. Based on an
assessment of the best available information regarding the status of
and threats to the golden paintbrush, we have determined that the
species no longer meets the definition of a threatened species or an
endangered species under the Act.
We have determined that golden paintbrush is not in danger of
extinction now nor likely to become so in the foreseeable future based
on a comprehensive review of its status and listing factors.
Specifically, our recent review indicated: (1) An increase in the known
number of occurrences of the species within its geographic range, and
increased abundance in many populations; (2) resiliency of the species
to existing and potential threats; (3) 45 of 48 sites with golden
paintbrush are in either public ownership; are owned by a conservation-
oriented, nongovernmental organization; or are under conservation
easement; and (4) the implementation of beneficial management practices
for the species. Accordingly, the golden paintbrush no longer meets the
definition of a threatened species or an endangered species under the
Act.
Peer review and public comment. The purpose of peer review is to
ensure that our determination regarding the status of the species under
the Act is based on scientifically sound data, assumptions, and
analyses. We prepared a species biological report (SBR) for golden
paintbrush (Service 2019) and sought peer review on the report 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 sent the report to four appropriate
and independent specialists with knowledge of the biology and ecology
of the golden paintbrush and received three responses. The comments and
recommendations of the peer reviewers have been incorporated into the
SBR as appropriate, and they informed the proposed rule. We posted the
peer reviews on https://www.regulations.gov under Docket No. FWS-R1-ES-
2020-0060. Furthermore, in our June 30, 2021, proposed rule (86 FR
34695), we requested that all interested parties submit written
comments on the proposal by August 30, 2021. We received 10 public
comments in response to the proposed rule as discussed below in Summary
of Comments and Recommendations.
[[Page 46089]]
Supporting Documents
Staff at the Washington Fish and Wildlife Office (WFWO), in
consultation with other species experts, prepared the SBR for golden
paintbrush (Service 2019). The report represents a compilation of the
best scientific and commercial data available concerning the status of
the species, including the impacts of past and present factors (both
negative and beneficial) affecting the species. The report formed the
scientific basis for our 5-year status review and this final rule. The
report is posted on https://www.regulations.gov under Docket No. FWS-
R1-ES-2020-0060.
Previous Federal Actions
On May 10, 1994, we published in the Federal Register (59 FR 24106)
a proposed rule to list the golden paintbrush as a threatened species
under the Act (16 U.S.C. 1531 et seq.). On June 11, 1997, we published
in the Federal Register (62 FR 31740) a final rule to list the species
as a threatened species under the Act. The final rule included a
determination that the designation of critical habitat for the golden
paintbrush was not prudent.
In August 2000, we finalized a recovery plan for the species
(Service 2000, entire), which we supplemented in May 2010 with the
final recovery plan for the prairie species of western Oregon and
southwestern Washington (Service 2010, entire).
On July 6, 2005, we initiated 5-year reviews for 33 plant and
animal species, including the golden paintbrush, under section 4(c)(2)
of the Act, and requested information on the species' status (see 70 FR
38972). The 5-year status review, completed in September 2007 (Service
2007, entire), resulted in a recommendation to maintain the status of
the golden paintbrush as threatened. The 2007 5-year status review is
available on the Service's website at https://ecos.fws.gov/docs/five_year_review/doc1764.pdf.
On January 22, 2018, we initiated 5-year status reviews for 18
plant and animal species, including the golden paintbrush, under
section 4(c)(2) of the Act, and requested information on the species'
status (see 83 FR 3014). In 2019, we completed our SBR (Service 2019).
On June 30, 2021, we published in the Federal Register (86 FR
34695) a proposed rule to remove golden paintbrush from the List, and
we made available our draft post-delisting monitoring plan for public
review and comment. Our proposed rule followed from the recommendation
of the most recent 5-year review for the golden paintbrush, as well as
the data and analysis contained in the SBR (Service 2019).
Summary of Changes From the Proposed Rule
In preparing this final rule, we reviewed and fully considered
comments from the public on the June 30, 2021, proposed rule (86 FR
34695) and the draft post-delisting monitoring plan. We updated
information presented in the proposed rule based on comments and
additional information provided as follows:
(1) We included updated survey information provided to the Service.
(2) We incorporated additional information regarding stressors and
potential threats to the species.
(3) We made many small, nonsubstantive clarifications and
corrections throughout this rule, including under Summary of Biological
Status and Threats, below, in order to ensure better consistency,
clarify some information, and update or add new references.
We considered whether this additional information altered our
analysis of the magnitude or severity of threats facing the species. We
conclude that the information we received during the comment period for
the proposed rule did not change our previous analysis of the magnitude
or severity of threats facing the species or our determination that
golden paintbrush is no longer a threatened species and warrants
delisting.
Background
Below, we summarize information for the golden paintbrush directly
relevant to this final rule. For more information on the description,
biology, ecology, and habitat of the golden paintbrush, please refer to
the SBR for golden paintbrush (Castilleja levisecta), completed in June
2019 (Service 2019, entire). The SBR is available under Supporting
Documents on https://www.regulations.gov in Docket No. FWS-R1-ES-2020-
0060. The SBR and other relevant supporting documents are available on
the golden paintbrush's species profile page on the Environmental
Conservation Online System (ECOS) at https://ecos.fws.gov/ecp/species/7706.
Species Description and Habitat Information
The golden paintbrush is native to the northwestern United States
and southwestern British Columbia. It has been historically reported
from more than 30 sites from Vancouver Island, British Columbia, to the
Willamette Valley of Oregon (Hitchcock et al. 1959, entire; Sheehan and
Sprague 1984, p. 5; Gamon 1995, pp. 5-7). The taxonomy of the golden
paintbrush as a full species is widely accepted as valid by the
scientific community (Integrated Taxonomic Information System (ITIS)
2020, entire).
The golden paintbrush is a short-lived perennial herb formerly
included in the figwort or snapdragon family (Scrophulariaceae), with
current classification in the Orobanchaceae family. The genus
Castilleja is hemiparasitic, with roots of paintbrushes capable of
forming parasitic connections to roots of other plants; however,
paintbrush plants are probably not host-specific (Mills and Kummerow
1988, entire) and can grow successfully, though not as well, even
without a host. Golden paintbrush has superior performance (survival,
height, number of flowering stems, number of fruiting stems, number of
seed capsules) where it co-occurs with certain prairie species,
including several perennial native forbs (e.g., common woolly sunflower
or Oregon sunshine (Eriophyllum lanatum) and common yarrow (Achillea
millefolium)), as well as species in other functional groups, including
grasses (e.g., Roemer's fescue (Festuca roemeri) and California
oatgrass (Danthonia californica)) and shrubs (e.g., snowberry
(Symphoricarpos albus)) (Schmidt 2016, pp. 10-17). Anecdotal
observations suggest that golden paintbrush grows poorly when
associated with annual grasses (Gamon 1995, p. 17).
Individual golden paintbrush plants have a median survival of 1 to
5 years, but some plants can survive for more than a decade (Service
2019, p. 7). Plants are up to 30 centimeters (cm) (12 inches (in)) tall
and are covered with soft, somewhat sticky hairs. Stems may be erect or
spreading, in the latter case giving the appearance of being several
plants, especially when in tall grass. The lower leaves are broader,
with one to three pairs of short lateral lobes. The bracts are softly
hairy and sticky, golden yellow, and about the same width as the upper
leaves.
Golden paintbrush plants typically emerge in early March, with
flowering generally beginning the last week in April and continuing
until early June. Most plants complete flowering by early to mid-June,
although occasionally plants flower throughout the summer and into
October. Based on historical collections and observations, flowering
seems to occur at about the same time throughout the species' range.
Individual plants of golden paintbrush typically need pollinators to
set seed. Bumble bee species (Bombus) appear to be the most common
pollinators visiting
[[Page 46090]]
golden paintbrush (Wentworth 1994, p. 5; Kolar and Fessler 2006, in
litt.; Waters 2018, in litt.; Kaye 2019, in litt.), although sweat bees
(Halictidae), miner bee (Andrena chlorogaster), syrphid fly (Eristalis
hirta), and bee fly (Bombylius major) have also been observed visiting
golden paintbrush plants (Kolar and Fessler 2006, in litt.; Waters
2018, in litt.).
Fruits typically mature from late June through July, with seed
capsules beginning to open and disperse seed in August. By mid-July,
plants at most sites are in senescence (the process of deterioration
with age), although this can vary considerably depending on available
moisture. Capsules persist on the plants well into the winter, and
often retain seed into the following spring. Seeds are likely shaken
from the seed capsules by wind, with most falling a short distance from
the parent plant (Godt et al. 2005, p. 88). The seeds are light
(approximately 8,000 seeds per gram) and could possibly be dispersed
short distances by wind (Kaye et al. 2012, p. 7). Additionally, there
is at least one reported instance of short-distance movement of seeds
via vole activity (Kolar and Fessler 2006, in litt.). Therefore,
natural colonization of new sites would likely occur only over short
distances as plants disperse from established sites. Germination tests
in different years with seed from various populations suggest that
germination rates can vary extremely widely both between sites and
between years (Wentworth 1994, entire). Germination tests also revealed
that seeds likely remain viable in the wild for several years
(Wentworth 1994, p. 17).
Individuals of the golden paintbrush require open prairie soils,
near-bedrock soils, or clayey alluvial soils with suitable host plants.
These suitable habitats occur from zero to 100 meters (330 feet) above
sea level (Service 2000, p. 5). The golden paintbrush may have
historically grown in deeper soils, but nearly all of these soils
within the known range of the species have been converted to
agriculture (Lawrence and Kaye 2006, p. 150; Dunwiddie and Martin 2016,
p. 1). Reintroduction efforts have targeted sites or microsites, with
features such as mounds or swales and deeper soils where these efforts
were more likely to be effective (Dunwiddie and Martin 2016, p. 15).
Populations currently occur on the mainland in the States of
Washington and Oregon, and on islands in the State of Washington and in
British Columbia, Canada. Mainland and island populations form two
broad categories of populations that can vary slightly in habitat
setting. Individuals in mainland populations are found in open,
undulating remnant prairies dominated by Roemer's fescue and red fescue
(Festuca rubra) on gravelly or clayey glacial outwash. Individuals in
island populations are often on the upper slopes or rims of steep,
southwest- or west-facing, sandy bluffs that are exposed to salt spray.
Individuals in island populations may also occur on remnant coastal
prairie flats on glacial deposits of sandy loam. Island prairies may
have historically been dominated by forbs and foothill sedge (Carex
tumulicola) rather than grasses (Washington Department of Natural
Resources (WDNR) 2004b, pp. 11, 17); however, many island sites are now
dominated by red fescue or weedy forbs. All golden paintbrush sites are
subject to encroachment by woody vegetation if not managed.
Historically, fire was significant in maintaining open prairie
conditions in parts of the range of the golden paintbrush (Boyd 1986,
p. 82; Gamon 1995, p. 14; Dunwiddie et al. 2001, p. 162). The golden
paintbrush is a poor competitor, intolerant of shade cast by
encroaching tall nonnatives and litter duff in fire-suppressed
prairies. Native perennial communities are likely to support more host
species appropriate for the golden paintbrush than those dominated by
nonnative annuals (Lawrence and Kaye 2011, p. 173). Thus, habitats with
low presence of nonnative annuals and high presence of a diverse
assemblage of perennial, native prairie species are more likely to
provide the best conditions for survival of golden paintbrush plants
year-to-year (Dunwiddie and Martin 2016, p. 1).
Range, Distribution, Abundance, and Trends of Golden Paintbrush
The golden paintbrush is endemic to the Pacific Northwest,
historically occurring from southeastern Vancouver Island and adjacent
islands in British Columbia, Canada, to the San Juan Islands and Puget
Trough in western Washington and into the Willamette Valley of western
Oregon (Fertig 2021, pp. 33-34).
Currently, the species occurs within British Columbia, Washington,
and Oregon, representing, generally, four geographic areas (British
Columbia, North Puget Sound, South Puget Sound, and the Willamette
Valley). The species' historical distribution--before European
settlement and modern development in the Pacific Northwest--is unknown.
However, the species' current distribution is generally representative
of the areas where we suspect the species occurred historically.
Since its Federal listing in 1997, only one new population of
golden paintbrush that was likely extant at the time of listing has
been discovered across the species' range (Service 2007, p. 6). All
other new populations across the range are the result of
reintroductions through outplanting or direct seeding. Seeds used to
grow plugs for outplanting, and plant stock for seed production, were
derived from populations that were extant at the time of listing
(referred to as ``wild sites'' in the SBR and other documents) (Service
2019, p. 5). Please note that in previous Service documents (Service
2000, Service 2007, Service 2019), the terms ``site'' and
``population'' were used interchangeably. For the purpose of this
document, we will use ``population'' to be more consistent with how the
data have been reported over time (Fertig 2019, pp. 11-38).
At the time of listing (see 62 FR 31740; June 11, 1997), there were
10 known golden paintbrush populations: 8 in Washington and 2 in
British Columbia. No golden paintbrush populations were known from
Oregon at the time of listing (Sheehan and Sprague 1984, pp. 8-9; WDNR
2004b, p. 2). Despite its limited geographic range and isolation of
populations, the golden paintbrush retained exceptionally high levels
of genetic diversity, possibly because there were several large
populations that remained (Godt et al. 2005, p. 87).
Since its Federal listing, the distribution and abundance of golden
paintbrush have increased significantly as a result of outplanting
(seeding or plugging). During the last rangewide assessment, a minimum
of 48 populations were documented (Service 2019, pp. 11-14). Based on
these data, in Washington, there are 19 populations: 5 in the South
Puget Sound prairie landscape, 6 in the San Juan Islands, 7 on Whidbey
Island, and 1 near Dungeness Bay in the Strait of Juan de Fuca. In
Oregon, there are 26 extant populations within the Willamette Valley.
In British Columbia, there are three extant populations, each located
on a separate island. Of these 48 populations, only 3 are on private
property (Service 2019, p. 12). The remaining 45 golden paintbrush
populations are in either public ownership; are owned by a
conservation-oriented, nongovernmental organization; or are under
conservation easement.
BILLING CODE 4333-15-P
[[Page 46091]]
[GRAPHIC] [TIFF OMITTED] TR19JY23.160
BILLING CODE 433-15-C
Trends in abundance for the golden paintbrush have been
consistently monitored since 2004 (Fertig 2021, pp. 11-38), with
refinements to monitoring protocols made in 2008 and 2011 (Arnett 2011,
entire). Rangewide abundance has substantially increased from
approximately 11,500 flowering plants in 2011, to more than 560,000
flowering plants counted in 2018 (Fertig 2021, p. 22). In 2019, the
number of
[[Page 46092]]
flowering plants declined to 325,320 (Fertig 2021, p. 22). Although
this appears to be a drop in abundance, we attribute the rapid increase
in abundance in 2018 to the development of direct seeding techniques
for establishing new populations, as opposed to outplanting individual
plants (or plugs) grown in greenhouses. Most of the populations in
Washington and Oregon's Willamette Valley were established by
incorporating direct seeding. The 2018 rangewide population abundance
was not necessarily reflective of the eventual long-term population
level at a site. A number of reestablished populations have been going
through a period of prairie development/progression and species
succession. For example, at some reestablished populations, abundance
initially increased over several years then dropped to about 15-20
percent of the peak abundance (Fertig 2021, pp. 23-27). Drops in
abundance are somewhat expected as the populations experience
variability after direct seeding, and we anticipate that long-term
population levels at these reestablished sites will meet recovery
criteria.
In 2020, there was a reduction of survey effort due to limitations
related to the COVID pandemic, and while the majority of populations
were surveyed consistently in Washington, 25 populations in Oregon were
not surveyed. The last 4 years of monitoring rangewide (2017-2020)
represent the 4 years with greatest abundance, even without data from
the 25 sites in Oregon that were not monitored in 2020 (Fertig 2021, p.
14). The year 2020 also represents the second highest abundance of
golden paintbrush in the State of Washington at 202,208 flowering
plants, which was a 47.8 percent increase from 136,846 in 2019 (Fertig
2021, p. 11).
In contrast to the newly established golden paintbrush populations
(referred to as ``outplantings''), there has been a steady decline in
overall abundance of the populations extant at the time of listing
since 2012. Abundance at these populations dropped from just over
15,500 flowering plants in 2012, to 2,223 flowering plants in 2020
(Fertig 2021, p. 11).
The Service considers the demographics and site conditions of all
golden paintbrush populations across the species' range when
determining the status of the species, including populations extant at
the time of listing, as well as new populations outplanted since the
time of listing. In past Service documents, the sites with populations
extant at the time of listing have often been referred to as ``wild''
sites, and trends of abundance have been tracked separately from
outplanted populations (see Fertig 2021, p. 14, and Service 2019, p.
30). Because seed from many of the populations extant at the time of
listing was used to establish populations across the range, all
outplanted populations have representation from original source
populations, though the outplanted populations have increased genetic
diversity from their source populations due to mixed-source production
beds (St. Clair et al. 2020, p. 590). While declines in abundance have
been occurring steadily in the populations extant at the time of
listing, we do not believe these sites should be considered ``wild'' or
different from outplanted populations, as many have been managed and/or
augmented over time and many share genetics with the outplanted
populations. Success of golden paintbrush outplantings has been
associated with microsites with deeper soils and high richness of
native perennial forbs (Dunwiddie and Martin 2016, p. 1); these
microsites were likely where golden paintbrush persisted historically,
but many of these were tilled for agricultural purposes or developed.
Many of the golden paintbrush populations extant at the time of listing
may represent marginal or less optimal remnant habitats or sites that
were not suitable for other uses (Dunwiddie et al. 2016, pp. 207-209).
For the purposes of assessing recovery of the species across its range,
the Service acknowledges that individual populations will vary in
viability, and these differences between populations have been
accounted for in our current condition analysis within the SBR (Service
2019, entire) and in our evaluation of the species' overall resiliency,
redundancy, and representation.
Recovery Criteria
Section 4(f) of the Act directs us to develop and implement
recovery plans for the conservation and survival of endangered and
threatened species unless we determine that such a plan will not
promote the conservation of the species. Under section 4(f)(1)(B)(ii),
recovery plans must, to the maximum extent practicable, include
objective, measurable criteria which, when met, would result in a
determination, in accordance with the provisions of section 4 of the
Act, that the species be removed from the Lists of Endangered and
Threatened Wildlife and Plants.
Recovery plans provide a roadmap for us and our partners on methods
of enhancing conservation and minimizing threats to listed species, as
well as measurable criteria against which to evaluate progress towards
recovery and assess the species' likely future condition. However, they
are not regulatory documents and do not substitute for the
determinations and promulgation of regulations required under section
4(a)(1) of the Act. A decision to revise the status of a species, or to
delist a species, is ultimately based on an analysis of the best
scientific and commercial data available to determine whether a species
is no longer an endangered species or a threatened species, regardless
of whether that information differs from the recovery plan.
There are many paths to accomplishing recovery of a species, and
recovery may be achieved without all of the criteria in a recovery plan
being fully met. For example, one or more criteria may be exceeded
while other criteria may not yet be accomplished. In that instance, we
may determine that the threats are minimized sufficiently and that the
species is robust enough that it no longer meets the Act's definition
of an endangered species or a threatened species. In other cases, we
may discover new recovery opportunities after having finalized the
recovery plan. Parties seeking to conserve the species may use these
opportunities instead of methods identified in the recovery plan.
Likewise, we may learn new information about the species after we
finalize the recovery plan. The new information may change the extent
to which existing criteria are appropriate for identifying recovery of
the species. The recovery of a species is a dynamic process requiring
adaptive management that may, or may not, follow all of the guidance
provided in a recovery plan.
Here, we provide a summary of progress made toward achieving the
recovery criteria for the golden paintbrush. More detailed information
related to conservation efforts can be found below under Summary of
Biological Status and Threats. We completed a final recovery plan for
the golden paintbrush in 2000 (Service 2000, entire), and later
supplemented the plan for part of the species' range in 2010 (Service
2010, entire). The 2000 plan includes objective, measurable criteria
for delisting; however, the plan has not been updated for more than 20
years, so some aspects of the plan may no longer reflect the best
scientific information available for the golden paintbrush.
Since about 2012, a significant increase in the number of new
populations has occurred, because of direct seeding within the species'
[[Page 46093]]
historical range in Washington and Oregon, with perhaps the most
significant being the reestablishment of the golden paintbrush at a
number of sites in Oregon's Willamette Valley, where the species was
once extirpated. In addition to improved propagation techniques,
substantial research has been conducted on the population biology, fire
ecology, and restoration of the golden paintbrush (Dunwiddie et al.
2001, entire; Gamon 2001, entire; Kaye and Lawrence 2003, entire;
Swenerton 2003, entire; Wayne 2004, entire; WDNR 2004b, entire;
Lawrence 2005, entire; Dunwiddie and Martin 2016, entire; Lawrence
2015, entire; Schmidt 2016, entire).
The results of these studies have been used to guide management of
the species at sites being managed for native prairie and grassland
ecosystems. Active management to promote the golden paintbrush is being
done to varying degrees (from targeted to infrequent) across prairie
and grassland sites. An active seed production program has been
maintained to provide golden paintbrush seeds and other native prairie
plant seeds to land managers for population augmentation and
restoration projects across the species' range in Washington and
Oregon. Additionally, as recommended by the recovery plan for the
golden paintbrush (Service 2000, p. 31), the State of Washington
prepared a reintroduction plan for the Service as both internal and
external guidance (WDNR 2004a, entire).
Below are the delisting criteria described in the 2000 golden
paintbrush recovery plan (Service 2000, p. 24), as supplemented in
2010, and the progress made to date in achieving each criterion.
Criterion 1 for Delisting
Criterion 1 is that there are at least 20 stable populations
distributed throughout the historical range of the species. To be
deemed stable, a population must maintain a 5-year running average
population size of at least 1,000 individuals, where the actual count
never falls below 1,000 individuals in any year. The golden paintbrush
technical team recommended in the 2007 5-year status review that this
criterion should be modified. Because it is impractical to count
individual vegetative plants, the team recommended that the criterion
should be modified to specifically account for a recovered population
as equal to 1,000 flowering individuals and known to be stable or
increasing as evidenced by population trends (Service 2007, p. 3).
While we did not officially amend or make an addendum to the recovery
plan to incorporate this recommendation, we accepted this as the best
way to count population abundance, since monitoring has consistently
counted flowering plants, following a standardized methodology set by
the Washington Department of Natural Resources Natural Heritage Program
(WNHP) (Arnett and Birkhauser 2008, entire; Arnett 2011, entire).
The Service supplemented this criterion in its 2010 recovery plan
for the prairie species of western Oregon and southwestern Washington
by identifying locations for golden paintbrush reintroductions,
specifically to establish five additional populations distributed
across at least three of the following recovery zones: Southwest
Washington, Portland, Salem East, Salem West, Corvallis East, Corvallis
West, Eugene East, and Eugene West. Priority was given to
reestablishing populations in zones with historical records of golden
paintbrush (Southwest Washington, Portland, Salem East, Corvallis East)
(Service 2010, p. IV-37).
Progress on Criterion 1
At the time of the proposed rule (data through 2018), 23
populations averaged at least 1,000 individuals per year over the 5-
year period, with 8 populations with a 5-year running average of at
least 1,000 individuals. As of 2020, 17 populations averaged at least
1,000 individual plants per year over the 5-year period with most
recent data from 2016 to 2020 (2015 to 2019 for sites with no data in
2020). Of these 17 populations, 7 had a 5-year running average of at
least 1,000 individuals, and an additional 6 populations had a 3-year
running average of at least 1,000 individuals (Gray 2022, in litt.). As
noted above, we only count flowering plants during monitoring, so in
most years a proportion of individual plants may not be represented in
annual counts because they are not flowering during surveys. While the
most recent data do not meet the recovery criteria (of 20 such
populations), we find that many of the species' populations are
sufficiently resilient to make up for the smaller number of populations
based on the following analysis.
Eight populations currently number in the tens of thousands of
individuals, the largest totaling 82,692 flowering plants (Glacial
Heritage) (Fertig 2021, pp. 16-20). Prior to listing, the largest known
population totaled just over 15,000 individuals (Rocky Prairie Natural
Area Preserve) (62 FR 31740; June 11, 1997). Abundance at these eight
populations is greater (approximately 10,000 or more flowering plants)
than the 1,000-individual threshold established at the time of the
drafting of the recovery plan for this species (Service 2019, pp. 12-
13). These large populations are distributed across the species' range
in both Oregon and Washington, contributing to the species' ability to
withstand stochastic or catastrophic events. Although it is likely that
a number of the more recently established populations are still
experiencing variability and may experience an initial peak in
abundance followed by a decline to a lower abundance level, these
larger populations are more likely to be self-sustaining in the wild
over time, are more able to withstand stochastic disturbance, have
higher viability, and face an overall lower risk of extirpation than
populations at or just above the threshold of 1,000 individuals.
In addition, there are now a minimum of 26 golden paintbrush
populations in western Oregon's Willamette Valley, and these
populations are distributed across 4 (Corvallis West, Salem West,
Portland, Eugene West) of the recovery zones (Kaye 2019, pp. 11-23)
identified in the 2010 supplement to the species' recovery plan
(Service 2010, pp. IV-4, IV-37). In summary, we conclude that
significant progress has been made toward achieving this criterion, and
for some populations, the progress is well beyond numerical levels that
were anticipated at the time of recovery criteria development. Although
we acknowledge annual variability of abundance across sites, at least
eight sites across Washington and Oregon number in the tens of
thousands of individuals (Fertig 2021, pp. 16-20), which significantly
surpasses the minimum 1,000-individual threshold. This number of
individuals increases our confidence that the overall viability of the
species is secured, despite having fewer than 20 populations with a 5-
year running average of at least 1,000 individuals. In addition, new
populations can now be more quickly established through direct seeding
and there are multiple sites where the species has recently been
seeded. There are also plans to add new outplantings into the future
(Fertig 2021, p. 11).
Criterion 2 for Delisting
Criterion 2 is that at least 15 populations over 1,000 individuals
are located on protected sites. In order for a site to be deemed
protected, it must be either owned or managed by a government agency or
private conservation organization that identifies maintenance of the
species as the
[[Page 46094]]
primary management objective for the site, or the site must be
protected by a permanent conservation easement or covenant that commits
present and future landowners to the conservation of the species.
Progress on Criterion 2
This recovery criterion has not been met as phrased in the recovery
plan, because the primary management objective of the protected sites
is not always to protect only golden paintbrush. However, we find that
the goal of the criterion, a significant number of populations under
conservation ownership protective of the species that are likely to be
self-sustaining over time, has been greatly exceeded. Forty-five of the
48 golden paintbrush sites are in either public ownership; are owned by
a conservation-oriented, nongovernmental organization; or are under
conservation easement (Service 2019, p. 62). Such ownership is expected
to protect sites from development and land use that would have long-
term, wide-ranging deleterious effects on this species. Additionally,
37 sites currently have management practices that at least preserve
essential characteristics of golden paintbrush habitat, and 24 sites
have management plans and resources for their implementation for
multiple years (Service 2019, pp. 40, 42-44). In addition, at least two
of the five conservation easement sites are also enrolled in the
Service's Partners for Fish and Wildlife Program, which provides
technical and financial assistance to private landowners to restore,
enhance, and manage private land to improve native habitat. At least 3
sites in Washington and 14 sites in Oregon also support other prairie-
dependent species currently listed as endangered or threatened species
under the Act, and another 5 are part of designated critical habitat
for one of these species. Therefore, we anticipate prairie management
or maintenance will be ongoing at these golden paintbrush sites for the
foreseeable future. Two of the three extant sites in British Columbia
that are managed by Parks Canada are also located within designated
``ecological reserves'' (Service 2019, p. 14). The level of management
specific to golden paintbrush varies at each site, but all sites are
generally being managed to conserve or restore native prairie or
grassland habitats. For additional detail on species management status
at sites, see the discussion under Summary of Biological Status and
Threats, below.
Criterion 3 for Delisting
Criterion 3 is that genetic material, in the form of seeds
adequately representing the geographic distribution or genetic
diversity within the species, is stored in a facility approved by the
Center for Plant Conservation.
Progress on Criterion 3
This recovery criterion is met. Seeds are being stored at two
approved facilities, the Rae Selling Berry Seed Bank at Portland State
University and the Miller Seed Vault at the University of Washington
Botanic Garden. In addition, the active seed production programs at the
Center for Natural Lands Management in the South Puget Sound,
Washington, and two smaller nurseries in the North Puget Sound,
Washington, continue to provide golden paintbrush seeds to land
managers for population augmentation and prairie restoration projects.
Production programs were started using seeds from nearly all the
populations extant at the time of listing to maintain existing genetic
diversity across the species' historical range and to allow for the
greatest opportunity for local adaptation at reintroduction sites.
Criterion 4 for Delisting
Criterion 4 is that post-delisting monitoring of the condition of
the species and the status of all individual populations is ready to
begin.
Progress on Criterion 4
We have developed a post-delisting monitoring plan in cooperation
with our lead State partners in Washington (Washington Department of
Natural Resources (WDNR)) and in Oregon (Oregon Department of
Agriculture (ODA)). The final post-delisting monitoring plan is
available for public review on https://www.regulations.gov under Docket
No. FWS-R1-ES-2020-0060. We anticipate that the WDNR's WNHP and ODA
will coordinate future monitoring. In the post-delisting monitoring
plan, we include the monitoring of, at a minimum, all populations
established and counted in 2018 that were identified in the SBR
(Service 2019, pp. 12-13). These populations will be monitored every
other year after final delisting for a 5-year period (i.e., three
times, in years 1, 3, and 5, after this final rule is effective).
Several key prairie conservation partners may choose to monitor these
golden paintbrush sites more frequently and may also choose to monitor
additional golden paintbrush sites as more become established across
the species' range in Oregon and Washington. Parks Canada oversees
periodic monitoring of the three extant populations within British
Columbia, Canada. Therefore, this recovery criterion is met.
Criterion 5 for Delisting
Criterion 5 is that post-delisting procedures for the ecological
management of habitats for all populations of golden paintbrush have
been initiated.
Progress on Criterion 5
This criterion has not been met as phrased in the recovery plan, as
procedures for ecological management for all populations are not in
place. However, we find that the intent of this criterion has been met
because a substantial proportion of known golden paintbrush sites,
i.e., 37 out of 48,--more than the 20 populations originally envisioned
for these recovery criteria--meet this criterion. At least 24 of the 48
golden paintbrush sites have had prairie or grassland management plans
in place for multiple years. An additional 13 sites that lack a long-
term management plan for the golden paintbrush receive basic
maintenance to preserve the prairie characteristics of golden
paintbrush habitat (Service 2019, pp. 42-44). As described earlier,
significant strides have been made in the ecological management
techniques for restoration and maintenance of prairie landscapes and
the reintroduction and management of golden paintbrush at these and
other sites. The current level of management varies across extant
sites, influenced by need, conservation partner capacity, and funding
availability. We anticipate ongoing management at a minimum of 37 of
these sites, although the level of management will continue to vary
across sites based on these same factors (Service 2019, pp. 40, 42-44)
(see additional discussion regarding ongoing site management under
Summary of Biological Status and Threats, below). The most actively
managed sites may include plantings, fencing, prescribed fire,
herbicide use for weed control, mowing, and controlled public use. As
described above under Criterion 2 for Delisting, at least 17 sites
currently contain multiple, prairie-dependent species and an additional
5 sites are designated critical habitat for another prairie-dependent
species. Those golden paintbrush sites that support multiple, prairie-
dependent species listed under the Act are anticipated to receive the
most consistent ecological management into the future. While this
recovery criterion has not been fully achieved (i.e., not all
populations have post-delisting management procedures in place),
ecological management of habitat
[[Page 46095]]
is expected to occur on the vast majority of the known sites and
management will occur on far more than the originally projected 15
sites identified above under Criterion 2 for Delisting.
With the more recently identified threat of hybridization from
harsh paintbrush (Castilleja hispida), additional measures are being
implemented and refined to address the impacts to golden paintbrush on
contaminated sites and prevent the spread of harsh paintbrush to
uncontaminated golden paintbrush sites in the South Puget Sound
geographic area in Washington. The Service has developed a strategy and
guidance document for securing golden paintbrush sites and outlining
solutions necessary for the long-term protection of golden paintbrush
from hybridization (Service et al. 2021, entire). In addition, the
Service has signed a memorandum of understanding (MOU) with our State
conservation partners to ensure hybridization is contained and the
conservation strategy is followed to benefit golden paintbrush while
supporting recovery of other sympatric (occurring within the same
geographical area) prairie species listed under the Act (Service et al.
2020, entire). We provide more information and discussion on the
hybridization conservation strategy and how it fits into the
conservation of golden paintbrush in Summary of Biological Status and
Threats, and our response to (15) Comment, below.
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 species' expected response and
the effects of the threats--in light of those actions and conditions
that will ameliorate the threats--on an individual, population, and
species level. We evaluate each threat and its expected effects on the
species, then analyze the cumulative effect of all of the threats on
the species as a whole. We also consider the cumulative effect of the
threats in light of those actions and conditions that will have
positive effects on the species, such as any existing regulatory
mechanisms or conservation efforts. The Secretary determines whether
the species meets the definition of an ``endangered species'' or a
``threatened species'' only after conducting this cumulative analysis
and describing the expected effect on the species now and in the
foreseeable future.
The Act does not define the term ``foreseeable future,'' which
appears in the statutory definition of ``threatened species.'' Our
implementing regulations at 50 CFR 424.11(d) set forth a framework for
evaluating the foreseeable future on a case-by-case basis. The term
foreseeable future extends only so far into the future as we 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 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.
For species that are already listed as endangered or threatened
species, this analysis of threats is an evaluation of both the threats
currently facing the species and the threats that are reasonably likely
to affect the species in the foreseeable future following the
downlisting or delisting and the removal of the Act's protections. A
recovered species is one that no longer meets the Act's definition of
an endangered species or a threatened species. For the golden
paintbrush, we consider 30 years to be a reasonable period of time
within which reliable predictions can be made for stressors and
species' response. This time period includes multiple generations of
the golden paintbrush, generally includes the term of and likely period
of response to many of the management plans for the species and/or its
habitat, and encompasses planning horizons for prairie habitat
conservation efforts (e.g., Dunwiddie and Bakker 2011, pp. 86-88;
Service 2011, entire; Altman et al. 2017, pp. 6, 20); additionally,
various global climate models and emission scenarios provide consistent
predictions within that timeframe (Intergovernmental Panel on Climate
Change (IPCC) 2014, p. 11). We consider 30 years a relatively
conservative timeframe in view of the long-term protection afforded to
93 percent of the species' occupied populations (45 of 48), which occur
on conserved/protected lands (Service 2019, p. 62).
Analytical Framework
The SBR documents the results of our comprehensive biological
review of the best scientific and commercial data regarding the status
of the species. The report does not represent our decision
[[Page 46096]]
on whether the species should be delisted 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 report, which can
be found at Docket FWS-R1-ES-2020-0060 on https://www.regulations.gov.
To assess golden paintbrush 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. We use
this information to inform our regulatory decision.
Summary of Biological Status and Threats
Below, we review the biological condition of the species and its
resources, and the threats that influence the species' condition in
order to assess the species' overall viability and the risks to that
viability. In addition, the SBR (Service 2019, entire) documents our
comprehensive biological status review for the species, including an
assessment of the potential threats to the species. The following
potential threats were identified for this species at the time of
listing: (1) Succession of prairie and grassland habitats to shrub and
forest lands (due to fire suppression, interspecific competition, and
invasive species); (2) development of property for commercial,
residential, and agricultural use; (3) low potential for expansion and
refugia due to constriction of habitat (from surrounding development or
land use); (4) recreational picking (including associated trampling);
and (5) herbivory (predation on plants and seeds) (62 FR 31740; June
11, 1997). For our analysis, we assessed the influence of these
potential threats on the current status of the species, as well as the
influence of two potential threats not considered at the time of
listing: hybridization of golden paintbrush with harsh paintbrush, and
the impacts of climate change. We also assessed current voluntary and
regulatory conservation mechanisms relative to how they reduce or
ameliorate existing threats to golden paintbrush.
Habitat Loss
At the time of listing, the principal cause of ongoing habitat loss
was succession of prairie and grassland habitats to shrub and forest
due to fire suppression, interspecific competition, and invasive
species (62 FR 31740; June 11, 1997). The potential for development at,
or surrounding, extant sites for commercial, residential, and
agricultural purposes also posed a threat to the golden paintbrush at
the time of listing. Both of these threat factors were preventing or
limiting extant populations from expanding and recruiting into new or
adjacent areas and afforded no refugia for the species in the case of
catastrophic events.
Currently, ongoing prairie or grassland management or maintenance
occurs at the majority of extant golden paintbrush sites. This
management includes removal or suppression of trees and both native and
nonnative woody shrubs, as well as control of nonnative, invasive
grassland plant species through a number of different approaches (e.g.,
mowing, prescribed fire, mechanical removal, selective-herbicide
application, restoration reseeding, etc.). Most golden paintbrush sites
have either had prairie or grassland management plans in place for
multiple years or receive basic maintenance to preserve the prairie
characteristics of golden paintbrush habitat (Service 2019, pp. 42-44).
Three golden paintbrush sites in Washington also currently support
other prairie- or grassland-dependent species listed under the Act--the
endangered Taylor's checkerspot butterfly (Euphydryas editha taylori)
and three threatened subspecies of Mazama pocket gopher (Thomomys
mazama spp.) (Olympia pocket gopher (Thomomys mazama pugetensis),
Tenino pocket gopher (Thomomys mazama tumuli), and Yelm pocket gopher
(Thomomys mazama yelmensis))--while an additional five sites in
Washington are included in designated critical habitat for the Taylor's
checkerspot butterfly.
Although these five critical habitat sites are currently unoccupied
by the Taylor's checkerspot butterfly, they were designated because
they were found to be essential for the conservation of the butterfly
(78 FR 61506; October 3, 2013). Harsh paintbrush (Castilleja hispida)
is a host plant for Taylor's checkerspot butterfly in the South Puget
Sound geographic area in Washington. As we discuss further below (see
Hybridization), golden paintbrush generally cannot co-occur with harsh
paintbrush due to the threat of hybridization. However, as we continue
to work with our conservation partners to follow the hybridization
strategy and guidance document to prioritize sites for both golden
paintbrush and Taylor's checkerspot butterfly we also continue to
explore opportunities to conserve both species on individual sites
where appropriate. In addition, at least 14 golden paintbrush sites in
Oregon's Willamette Valley currently support one or more other prairie-
or grassland-dependent species listed under the Act that do not present
the threat of hybridization--the endangered Fender's blue butterfly
(Icaricia icarioides fenderi), endangered Willamette daisy (Erigeron
decumbens), threatened Kincaid's lupine (Lupinus oreganus var.
kincaidii, listed as Lupinus sulphureus ssp. kincaidii), and threatened
Nelson's checker-mallow (Sidalcea nelsoniana) (Institute for Applied
Ecology 2019, in litt.).
We expect a number of golden paintbrush sites in both Washington
and Oregon to continue to be managed in a way that supports the
recovery of other prairie- or grassland-dependent species in addition
to the long-term conservation of the golden paintbrush. As long as
periodic management or maintenance continues to occur at golden
paintbrush sites across the species' range, the threat of prairie or
grassland succession is expected to remain adequately addressed into
the foreseeable future. State and Federal management plans include
specific objectives to continue to protect and conserve the golden
paintbrush at a number of sites. States, Federal agencies, and
conservation organizations have invested significant resources into
golden paintbrush recovery, as well as general prairie and grassland
restoration and conservation for a variety of at-risk, prairie-
dependent species. We do not anticipate habitat for these prairie-
dependent species to contract further given the limited amount of
remaining prairie habitat and the long-term investments conservation
partners have made, and continue to make, to restore, rebuild,
maintain, and conserve these relatively rare regional
[[Page 46097]]
ecosystems (Dunwiddie and Bakker 2011, entire; Center for Natural Lands
Management 2012, in litt., entire; The News Tribune 2014, in litt.;
Altman et al. 2017, entire; The Nature Conservancy 2019, in litt.,
entire).
Golden paintbrush now occurs within 48 separate populations as a
result of the numerous reintroduction efforts implemented to recover
this species. Only three of these populations are on lands possibly
subject to future development. The remaining 45 populations are all
under some type of public or conservation ownership (Service 2019, pp.
11-14). Of the 48 extant populations, at least 81 percent (n=39) are on
land with some known level of protected status (at a minimum, formally
protected as a natural area or other such designation, although not all
of these designations are permanent) (Service 2019, pp. 42-44). In
addition, of the 39 populations with some protected land status, 19
also include stipulations for, or statements of specific protection of,
perpetual management of the golden paintbrush.
Although the total area occupied by the golden paintbrush at 19 of
the 48 sites is relatively small (less than 0.4 hectare (ha) (1 acre
(ac)), 14 of the 48 sites have between 0.4 to 1.6 occupied ha (1 to 3.9
ac), and another 14 of the 48 sites have from between 2 to 18.6
occupied ha (5 to 46 ac). We lack this information at one site (Service
2019, pp. 37-38). All but 4 of the 48 sites have available land for
future golden paintbrush population expansion or shifts in
distribution. Of the 33 sites with less than 2 ha (5 ac) of occupied
habitat, 10 have an estimated range of 0.8 to 2 ha (2 to 5 ac) of
additional habitat for expansion, and at least 13 have an estimated
range of 2 to 6 ha (5 to 15 ac) of additional habitat for future
expansion (Service 2019, pp. 37-38). In addition, the species is much
less reliant on expanding site-use and refugia than at the time of
listing, when only 10 extant populations of the golden paintbrush
remained. The reintroduction and seed production techniques developed
for golden paintbrush recovery have provided the means to more easily
establish or reestablish populations at prairie restoration sites than
were previously possible. Many of these sites have been specifically
acquired for their potential overall size, conservation value, and
conservation status. The golden paintbrush has been reintroduced and
established at prairie restoration sites that are well-distributed
across the species' historical range, well beyond the 10 extant sites
at the time of listing. As a result of these conditions, we do not
anticipate development in or around these sites to become a threat to
the golden paintbrush in the foreseeable future.
Recreational Picking and Trampling
At the time of listing, we considered overutilization from
recreational picking (flowers) to be a threat (62 FR 31740; June 11,
1997). Our concern with recreational picking or collection of flowers
was that it would reduce overall potential seed-set at a population.
Concern has also been noted regarding the direct harvesting of seed
capsules (Dunwiddie 2018, in litt.). Although there is evidence of
occasional recreational or possible commercial collection of capsules
that reduced the amount of seed available on a site, collection is no
longer considered a significant stressor to the species across its
range (Service 2019, p. 47). In addition, the current number of
established and protected golden paintbrush populations, many with
limited or restricted access, largely ameliorates this previously
identified threat. We acknowledge that the golden paintbrush is likely
a desirable species for some gardeners or plant collectors. However,
when delisted (see DATES, above), golden paintbrush seeds or plants are
likely to become available through controlled sale to the public from
regional prairie conservation partners and/or regional native plant
nurseries, similar to what occurs with other non-listed prairie plant
species. For these reasons, we do not expect the possible collection of
golden paintbrush flowers or seeds to become a threat to the species in
the foreseeable future.
At the time of listing, we identified trampling of golden
paintbrush plants by recreationalists as impacting the species at some
sites with high levels of public use, especially where and when
associated with recreational picking of golden paintbrush flowers.
Although some risk of trampling to plants will always be present across
public sites (e.g., State parks, national wildlife refuges), most sites
often have some level of restricted access when golden paintbrush
plants are in bloom (e.g., fenced from deer or inaccessible to the
public) or there are defined walking or viewing areas. Therefore, when
compared with the potential impact of trampling at the time of listing,
the current impact is likely insignificant, due to the number of
reestablished golden paintbrush populations, the large size of many of
these sites, and considerable abundance of golden paintbrush plants at
some of these sites. For the above reasons, we also do not anticipate
that trampling will become a threat in the foreseeable future.
Herbivory
At the time of listing, we considered predation (herbivory) on the
golden paintbrush by native (voles and deer) and introduced (rabbits)
species to be a threat to the plant (62 FR 31740; June 11, 1997);
however, the best available information does not indicate it is a
current or future threat. Although deer and elk exhibit herbivory on
the golden paintbrush at some sites, there is annual and site-specific
variability in the overall level of herbivory (Service 2019, p. 48;
Martin 2021, p. 9). Herbivory impacts from rabbits and voles on the
golden paintbrush have not been broadly or consistently observed and
also appear to be variable across sites and years. Where herbivory by
deer or rabbits or both has been significant, control with fencing has
been successfully implemented, but controlling herbivory through
fencing over large areas is limited by cost (Service 2019, p. 48). In
addition, encouraging localized reduction of deer populations through
lethal removal near some sites (Washington Department of Fish and
Wildlife 2019, in litt.; Pelant 2019, in litt.) and installing raptor
perch poles to control rodents and rabbits at some sites are also being
implemented to reduce impacts of herbivory on the golden paintbrush
(Service 2019, p. 48). As a consequence of the significant increase in
the number of golden paintbrush populations that have been successfully
established across the species' range since it was listed, and because
the impact of herbivory is being adequately managed in at least a
portion of those sites where noted as significant (potential site- or
population-level effect), we conclude predation (herbivory) no longer
has a significant impact across the majority of the golden paintbrush's
48 sites/populations, nor at the species level, and it is unlikely to
become a threat to the species in the foreseeable future.
Hybridization
As noted above, a potential threat to the golden paintbrush
identified after the species was listed in 1997 was the impact of
hybridization with the harsh paintbrush. The harsh paintbrush is one of
the host plants introduced to prairie sites targeted for endangered
Taylor's checkerspot butterfly recovery efforts. Our 2007 5-year status
review recommended, ``the evaluation of the potential for genetic
contamination of golden paintbrush populations by hybridization with
other species of Castilleja'' (Service 2007, p. 15). After
[[Page 46098]]
initial evaluation, the potential risk of hybridization was considered
relatively low and manageable (Kaye and Blakeley-Smith 2008, p. 13).
However, after further evaluation and additional observations in the
field, hybridization with the harsh paintbrush has now been identified
as a significant potential threat to golden paintbrush populations
where the two species occur together or in close proximity (Clark 2015,
entire; Sandlin 2018, entire). Three former golden paintbrush recovery
sites have now been discounted by the Service for the purposes of
recovery due to the level of hybridization at these sites (Service
2019, p. 15). At least one other site is currently vulnerable to the
effects of hybridization, but management efforts to date (removal of
plants that exhibit hybrid characteristics and creation of a zone of
separation between harsh paintbrush and golden paintbrush areas at the
site) have maintained this golden paintbrush population. Currently,
hybridization appears to be confined to those areas located in the
South Puget Sound prairie region where both species of Castilleja were
used at some of the same habitat restoration sites. The only known
incident of hybridization outside of this region was at Steigerwald
Lake National Wildlife Refuge in southwestern Washington, where we
unknowingly used a seed mix that included the harsh paintbrush. This
site has since been eradicated of both Castilleja species, but we
anticipate reintroducing the golden paintbrush to the site in the
future (Ridgefield National Wildlife Refuge Complex 2019, in litt.,
entire).
As a response to this emerging threat, efforts were implemented,
and are ongoing, to reduce or eliminate the risk of hybridization to
the golden paintbrush. These include efforts such as maintaining
isolated growing areas for the golden paintbrush and harsh paintbrush
at native seed production facilities used in prairie restoration
efforts, maintaining buffers between golden paintbrush and harsh
paintbrush patches at sites where both species are currently present,
and delineating which of the two species will be used at current and
future prairie conservation or restoration sites. We recently developed
a strategy and guidance document for securing golden paintbrush sites
to address containment of hybridization at existing contaminated sites
and prevention of unintentional spread of hybridization to other
regions within the golden paintbrush's range, specifically north Puget
Sound and the Willamette Valley (Service et al. 2021, entire). We have
also entered into an associated MOU with the Washington Department of
Fish and Wildlife (WDFW) and WDNR to ensure the strategy is implemented
as agreed to by all prairie conservation partners in the range of the
golden paintbrush (Service et al. 2020, entire). The three agencies
have authority over these species and will oversee most prairie
restoration efforts in Washington, particularly in South Puget Sound.
This MOU is expected to facilitate awareness and compliance with the
hybridization strategy and guidance by our prairie conservation
partners across the range of the golden paintbrush. The formal adoption
and implementation of the hybridization strategy and guidance is
expected to prevent hybridization from becoming a threat to the golden
paintbrush in the foreseeable future. Please see our response to (12)
Comment, below, for additional discussion regarding hybridization.
Climate Change
At the time of listing, the potential impacts of climate change on
the golden paintbrush were not discussed. The term ``climate'' refers
to the mean and variability of relevant quantities (i.e., temperature,
precipitation, wind) over time (IPCC 2014, pp. 119-120). The term
``climate change'' thus refers to a change in the mean or variability
of one or more measures of climate (e.g., temperature or precipitation)
that persists for an extended period, typically decades or longer,
whether the change is due to internal processes or anthropogenic
changes (IPCC 2014, p. 120).
Scientific measurements spanning several decades demonstrate that
changes in climate are occurring. In particular, warming of the climate
system is unequivocal, and many of the observed changes in the last 60
years are unprecedented over decades to millennia (IPCC 2014, p. 2).
The current rate of climate change may be as fast as any extended
warming period over the past 65 million years and is projected to
accelerate over the next 30 to 80 years (National Research Council
2013, p. 5). Thus, rapid climate change is adding to other sources of
extinction pressures, such as land use and invasive species, which will
likely place extinction rates in this era among just a handful of the
severe biodiversity crises observed in Earth's geological record
(American Association for the Advancement of Science (AAAS) 2014, p.
7).
Global climate projections are informative, and in some cases, the
only or the best scientific information available for us to use.
However, projected changes in climate at the global scale and related
impacts can vary substantially across and within different regions of
the world (e.g., IPCC 2013 and 2014, entire) and within the United
States (Melillo et al. 2014, entire). Therefore, we use ``downscaled''
projections when they are available and have been developed through
appropriate scientific procedures, because such projections provide
higher resolution information that is more relevant to spatial scales
used for analyses of a given species (see Glick et al. 2011, pp. 58-61,
for a discussion of downscaling).
Climate change trends predicted for the Pacific Northwest (Oregon,
Washington, Idaho, and Montana) broadly consist of an increase in
annual average temperature; an increase in extreme precipitation
events; and, with less certainty, variability in annual precipitation
(Bachelet et al. 2011, p. 413; Dalton et al. 2013, pp. 31-38, figure
1.1; Snover et al. 2013, pp. 5-1-5-4).
Based on a 2014 climate change vulnerability assessment, the golden
paintbrush was considered ``presumed stable'' (Gamon 2014, entire).
After the completion of the SBR (Service 2019, entire), a new
assessment was conducted on sites in Washington, which evaluated only
the populations extant at the time of listing (11 extant and 11
populations that were extirpated; none of the 10 outplanted sites in
Washington); this new assessment considered golden paintbrush as
``highly vulnerable'' to climate change (Young et al. 2016, entire;
Kleinknecht et al. 2019, entire). Please see our response to (10)
Comment, below, for more discussion regarding this new information.
Prolonged or more intense summer droughts are likely to increase in
the Pacific Northwest due to climate change (Snover et al. 2013, p. 2-
1). Regional climate change literature suggests that prairie ecosystems
were established under warmer and drier conditions and are unlikely to
be disadvantaged from future increased summer drought (Bachelet et al.
2011, p. 417). However, although the golden paintbrush senesces as the
prairies dry out in the summer, increased intensity or length of
drought conditions will likely stress plants and increase mortality,
resulting in reduced numbers of individuals in populations at less-
than-optimal sites (Kaye 2018, in litt.).
As is the case with all stressors we assess, even if we conclude
that a species is currently affected or is likely to be affected in a
negative way by one or more climate-related impacts, it does not
necessarily follow that the species
[[Page 46099]]
meets the definition of an ``endangered species'' or a ``threatened
species'' under the Act.
Predicted environmental changes resulting from climate change may
have both positive and negative effects on the golden paintbrush,
depending on the extent and type of impact and depending on site-
specific conditions within each habitat type. The primary predicted
negative effect includes drought conditions resulting in inconsistent
growing seasons. Likewise, future temperature changes may influence the
timing of native prairie plant phenology, which could lead to
asynchronies with pollinators (Reed et al. 2019, entire). This effect
will likely be buffered by the ability of the golden paintbrush to
survive in a range of soil conditions, as is evident by its
establishment on a wide variety of sites across its 300-mile geographic
range, with a number of different host plants, and under a range of
precipitation levels. We have not identified any predicted
environmental effects from climate change that may be positive for the
golden paintbrush at this time. Climate change could result in a
decline or change in bumble bee diversity within the range of the
golden paintbrush (Soroye et al. 2020, entire); the bumble bee is an
important pollinator for the golden paintbrush (Service 2019, pp. 6-7).
However, there are limited data at this time to indicate the potential
loss of bumble bee diversity is a specific and present threat to the
golden paintbrush. Also, observations of reduced seed production at
some Washington sites in recent years (2019-2021) could be the result
of recent drought events, although it remains unclear how these
observations translate to population abundance and trends over time.
Golden paintbrush populations can experience high variability in
abundance between years (Fertig 2021, pp. 24-27), and while climate
change is a stressor, given the species' high abundance and
distribution across the 300-mile range from British Columbia to Oregon,
we expect the golden paintbrush has sufficient resiliency and
redundancy to remain viable into the foreseeable future. Establishing
plant populations such as the golden paintbrush across the full
geographic and climatic range of Pacific Northwest prairies has been
identified as a ``climate-smart'' strategy given the extensive north-
south range encompassing variable temperature and precipitation
patterns (Bachelet et al. 2011, p. 420). The species appears to have
sufficient resiliency and redundancy across its range to maintain
sufficient viability during drought years. As evidence, the last 4
years of monitoring (2017-2020) represent the 4 years with greatest
abundance rangewide despite extreme drought experienced between 2015
and 2016 in Oregon and Washington (Fertig 2021, p. 30; National Oceanic
and Atmospheric Administration National Integrated Drought Information
System (NOAA NIDIS) 2022, entire). In addition, the year 2020 also
represents the second-highest abundance of golden paintbrush in the
State of Washington at 202,208 flowering plants, which was a 47.8
percent increase from 136,846 in 2019. Additionally, several
outplantings have been initiated at new locations since 2018 in
Washington, and we are continuing to work with our partners to plan new
outplantings across the species' range that will further add to the
species' resiliency and redundancy.
In summary, climate change is affecting, and will continue to
affect, temperature and precipitation events within the range of the
golden paintbrush. The extent, duration, and impact of those changes
are unknown, but could potentially increase or decrease precipitation
in some areas and increase temperatures found within the range of the
golden paintbrush. Golden paintbrush may experience climate change-
related effects in the future, most likely at the individual or local
population scale; however, we anticipate the species will remain
viable, because: (1) It is more resilient than at the time of listing
as a result of increased abundance, number of sites, and geographic
distribution in a variety of ecological settings, contributing to the
species' resiliency, redundancy, and representation; (2) available
information indicates the golden paintbrush is somewhat adaptable to
some level of future variation in climate conditions (Service 2019, pp.
22-25, 45); (3) there are ongoing efforts to expand the golden
paintbrush to additional suitable sites across the species' range; and
(4) we now have the technical ability to effectively and more readily
establish populations, which could help to mitigate future population
losses. Therefore, based upon the best available scientific and
commercial information, we conclude that climate change does not
currently pose a threat to the golden paintbrush, nor is it likely to
become a threat to the golden paintbrush in the foreseeable future
(next 30 years).
Voluntary and Regulatory Conservation Mechanisms
For current federally listed species, we consider existing
regulatory mechanisms relative to how they reduce or ameliorate threats
to the species absent the protections of the Act. Therefore, we examine
whether other regulatory mechanisms would remain in place if the
species were delisted, and the extent to which those mechanisms will
continue to help ensure that future threats will be reduced or
eliminated. In the final listing rule (62 FR 31740; June 11, 1997), we
noted that habitat management for the golden paintbrush was not
assured, despite the fact that most populations occurred in areas
designated as reserves or parks that typically afforded the golden
paintbrush and its habitat some level of protection through those
designations. As discussed in our SBR (Service 2019, pp. 47-52), the
threat of habitat loss from potential residential or commercial
development has decreased since the time of listing due to the
establishment of new golden paintbrush populations on protected sites.
Although a few privately owned sites are still at some potential risk,
development is no longer considered a significant threat to the
viability of the golden paintbrush due to the number of sites largely
provided protection from development (Service 2019, pp. 12-14).
Federal
Sikes Act--The Sikes Act (16 U.S.C. 670 et seq.) provides the
authority and defines the responsibilities to facilitate effectual
planning, development, maintenance, and coordination of wildlife, fish,
and game conservation and rehabilitation on military installations. The
Sikes Act requires that conservation goals are cooperatively developed
and recorded in a planning document called an integrated natural
resources management plant (INRMP). One golden paintbrush population
currently occurs on a Federal military installation (Forbes Point,
Naval Air Station Whidbey Island in Island County, Washington) and is
managed under an INRMP (U.S. Department of Defense (USDOD) 2013, pp. 3-
7) authorized by the Sikes Act. Special management and protection
requirements for golden paintbrush habitat in the INRMP include
maintenance of a 10-ac management area for the species, including:
maintaining and improving a fence around the population to exclude both
people and herbivores; posting signs that state the area is accessible
to ``authorized personnel only''; mowing and hand-cutting competing
shrubs in the area; outplanting nursery-grown plants from seeds
previously collected onsite; and implementing additional habitat
management actions, such as controlled burns or herbicide control of
[[Page 46100]]
competing vegetation, that are identified in the future to enhance the
golden paintbrush population (USDOD 2013, pp. 3-7). These protections
are effective in protecting the golden paintbrush on this site and are
expected to continue in the absence of protections under the Act
because the Sikes Act mandates the Department of Defense to conserve
and rehabilitate wildlife, fish, and game on military installations.
National Wildlife Refuge System Improvement Act--Ten golden
paintbrush populations currently occur on National Wildlife Refuge
(NWR) lands (Dungeness NWR in Washington; and Ankeny, William L.
Finley, Tualatin River, and Baskett Slough NWRs in Oregon). As directed
by the National Wildlife Refuge System Improvement Act of 1997 (Pub. L.
105-57), refuge managers have the authority and responsibility to
protect native ecosystems, fulfill the purposes for which an individual
refuge was founded, and implement strategies to achieve the goals and
objectives stated in management plans. For example, William L. Finley
NWR (Benton County, Oregon) includes extensive habitat for the golden
paintbrush, including four known populations, while a number of
additional NWRs in Oregon (Ankeny NWR, Marion County; Tualatin River
NWR, Washington County; and Baskett Slough NWR, Polk County) and
Washington (Dungeness NWR, Clallam County) each also support at least
one golden paintbrush population.
The Willamette Valley comprehensive conservation plan (CCP) for
William L. Finley, Ankeny, and Baskett Slough NWRs is a land management
plan finalized in 2011 with a 15-year term that directs maintenance,
protection, and restoration of the species and its habitat and
identifies specific objectives related to establishment of populations
and monitoring, as well as related habitat maintenance/management
(Service 2011, pp. 2-45-2-46, 2-66-2-70). Given the 15-year timeframe
of CCPs, these protections would remain in place until at least 2026,
regardless of the golden paintbrush's Federal listing status.
Tualatin River NWR finalized a CCP in 2013 (Service 2013a, entire),
and although it does not have conservation actions specific to the
golden paintbrush identified in the plan, it does have maintenance and
management activities for oak savanna habitat on the NWR, which
supports the golden paintbrush (Service 2013a, pp. 4-9-4-10). These
activities include various methods (e.g., mechanical and chemical) for
reducing encroachment of woody species, controlling nonnative and
invasive plant species, and reestablishing native grasses and forbs.
Given the 15-year timeframe of CCPs, protections outlined in the
Tualatin River NWR CCP are expected to remain in place until at least
2028, regardless of the golden paintbrush's Federal listing status.
Dungeness NWR also finalized a CCP in 2013 (Service 2013b, entire).
The CCP does not have any conservation actions specific to the golden
paintbrush identified; however, it does identify general actions taken
to control nonnative and invasive plant species that invade habitats on
the refuge, including those inhabited by the golden paintbrush (Service
2013b, pp. 4-44-4-45). The golden paintbrush population at this NWR's
headquarters continues to be maintained and protected.
In addition to specific protections for the golden paintbrush
provided under CCPs, the species is permanently protected by the
mission of all NWRs to manage their lands and waters for the
conservation of fish, wildlife, and plant resources and their habitats.
National Park Service Organic Act--One golden paintbrush site
currently occurs on National Park Service (NPS) lands (American Camp,
San Juan Island National Historical Park, Washington). The NPS Organic
Act of 1916 (54 U.S.C. 100101 et seq.), as amended, states the NPS will
promote and regulate the use of the National Park system to conserve
the scenery, natural and historic objects, and wildlife therein, to
provide for the enjoyment of the same in such manner and by such means
as will leave them unimpaired for the enjoyment of future generations
(54 U.S.C. 100101(a)). Further, in title 36 of the Code of Federal
Regulations (CFR) at Sec. 2.1(a)(1)(ii), NPS regulations specifically
prohibit possessing, destroying, injuring, defacing, removing, digging,
or disturbing from their natural state plants, or the parts or products
thereof, on lands under NPS jurisdiction. This prohibition extends to
the golden paintbrush where it exists on NPS-managed lands. In
addition, the General Management Plan for the San Juan Island National
Historical Park includes the NPS's goal of restoring a prairie
community that support functions and values of native habitat,
including habitat for native wildlife and rare species, such as the
golden paintbrush (NPS 2008, p. 249).
Endangered Species Act--The golden paintbrush often co-occurs with
other plant and animal species that are listed under the Act, such as
the endangered Willamette daisy and endangered Taylor's checkerspot
butterfly. Therefore, some of the general habitat protections (e.g.,
section 7 consultation and ongoing recovery implementation efforts,
including prairie habitat restoration, maintenance, and protection) for
these other prairie-dependent, listed species will indirectly extend to
some golden paintbrush sites when we delist the golden paintbrush. We
acknowledge that some sites that support Taylor's checkerspot butterfly
will not be available for golden paintbrush due to the threat of
hybridization between golden and harsh paintbrush; however, given that
hybridization has only impacted populations in the South Puget Sound
area of Washington, and the extensive range of golden paintbrush in
other areas where hybridization is currently not a threat, we assume
that management for prairie-dependent species across the range will
benefit golden paintbrush beyond delisting. Likewise, the hybridization
strategy and guidance document and our partnership with State agencies
in Washington will ensure that hybridization is minimized or avoided
into the future (Service et al. 2020, entire; Service et al. 2021,
entire).
Protections in Canada--The golden paintbrush in Canada is currently
federally listed as ``endangered'' under the Species at Risk Act (SARA)
(COSEWIC 2007, entire). SARA regulations protect species from harm,
possession, collection, buying, selling, or trading (Statutes of Canada
2002, c. 29). SARA also prohibits damage to or destroying the habitat
of a species that is listed as an endangered species. The population at
Trial Island is on Canadian federal lands protected under SARA (COSEWIC
2011, in litt., p. 5). The golden paintbrush is not currently protected
under any provincial legislation in British Columbia. However, the
golden paintbrush occurs in the ecological reserves that include Trial
Island and Alpha Islet, which are protected under the British Columbia
Park Act (COSEWIC 2011, in litt., p. 5). The British Columbia Park Act
allows lands identified under the Ecological Reserve Act to be
regulated to restrict or prohibit any use, development, or occupation
of the land or any use or development of the natural resources in an
ecological reserve (Revised Statutes of British Columbia 1996, c. 103).
This includes particular areas where rare or endangered native plants
and animals in their natural habitat may be preserved.
State
Washington Natural Heritage Plan--Washington State's Natural
Heritage Plan identifies priorities for preserving natural diversity in
Washington State (WDNR 2018, entire). The plan aids WDNR in conserving
key habitats that
[[Page 46101]]
are currently imperiled, or are expected to be imperiled in the future.
The prioritization of conservation efforts provided by this plan is
expected to remain in place if we delist the golden paintbrush. The
golden paintbrush is currently identified as a priority 2 species
(species likely to become endangered across their range or in
Washington within the foreseeable future) in the State's 2018 plan
(WDNR 2018a, in litt., p. 4), which is a recent change from the
species' priority 1 designation (species are in danger of extinction
across their range, including Washington) in 2011 (WDNR 2018b, in
litt., p. 2). The State's conservation status is not necessarily
impacted by Federal delisting and is ultimately at the discretion of
WDNR. We anticipate that WDNR will continue to monitor the species
where it occurs on their own lands and more broadly as a partner in the
post-delisting monitoring plan. We also anticipate that WDNR will
continue to actively manage their golden paintbrush sites because these
areas are not only important to the long-term conservation of golden
paintbrush, but also to other at-risk prairie species.
Washington State Park Regulations and Management--In Washington,
State park regulations, in general, require an evaluation of any
activity conducted on a park that has the potential to damage park
resources, and require mitigation as appropriate (see title 352 of the
Washington Administrative Code). Wildlife, plants, all park buildings,
signs, tables, and other structures are protected; removal or damage of
any kind is prohibited (Washington State Parks and Recreation
Commission 2019, in litt., p. 2). One golden paintbrush site currently
exists on Fort Casey Historical State Park. One of the objectives for
natural resources on Fort Casey Historical State Park under the Central
Whidbey State Parks Management Plan is to protect and participate in
the recovery of the golden paintbrush, including protecting native
plant communities, managing vegetative succession, and removing weeds
through integrated pest management (Washington State Parks and
Recreation Commission 2008, p. 15). The plan further states that areas
where the golden paintbrush occurs will be classified as ``heritage
affording a high degree of protection,'' and the Nass Natural Area
Preserve (also known as Admiralty Inlet Natural Area Preserve) is
included in the long-term park boundary to also assure continued
preservation of the golden paintbrush in this area (Washington State
Parks and Recreation Commission 2008, p. 26).
Oregon Revised Statutes (ORS), Chapter 564--Oregon Revised
Statutes, chapter 564, ``Wildflowers; Threatened or Endangered
Plants,'' requires State agencies to protect State-listed plant species
found on their lands. Any land action on Oregon land owned or leased by
the State, for which the State holds a recorded easement, and which
results, or might result, in the taking of an endangered or threatened
plant species, requires consultation with Oregon Department of
Agriculture staff (see ORS section 564.115). The golden paintbrush is
currently State-listed as endangered in Oregon. At this time, no
populations of the golden paintbrush are known to occur on State lands
in Oregon. However, should populations of the golden paintbrush occur
on Oregon State lands in the future, the removal of Federal protections
for the golden paintbrush would not affect State protection of the
species under this statute.
In summary, conservation measures and existing regulatory
mechanisms have minimized, and are continuing to address, the
previously identified threats to the golden paintbrush, including
habitat succession of prairie and grassland habitats to shrub and
forest lands; development of property for commercial, residential, and
agricultural use; recreational picking (including associated
trampling); and herbivory (on plants and seeds). As indicated above, we
anticipate the majority of these mechanisms will remain in place
regardless of the species' Federal listing status.
Cumulative Impacts
When multiple stressors co-occur, one may exacerbate the effects of
the other, leading to effects not accounted for when each stressor is
analyzed individually. The full impact of these synergistic effects may
be observed within a short period of time, or may take many years
before it is noticeable. For example, high levels of predation
(herbivory) on the golden paintbrush by deer could cause large
temporary losses in seed production in a population, but are not
generally considered to be a significant threat to long-term viability,
as populations that are relatively large and well-distributed should be
able to withstand such naturally occurring events. However, the
relative impact of predation (herbivory) by deer may be intensified
when it occurs in conjunction with other factors that may lessen the
resiliency of golden paintbrush populations, such as prolonged woody
species encroachment (prairie succession); extensive nonnative,
invasive plant infestations; or possible increased plant mortality
resulting from the effects of climate change (i.e., prolonged drought).
Although the types, magnitude, or extent of potential cumulative
impacts are difficult to predict, we are not aware of any combination
of factors that is likely to co-occur resulting in significant negative
consequences for the species. We anticipate that any negative
consequence of co-occurring threats will be successfully addressed
through the same active management actions that have contributed to the
ongoing recovery of the golden paintbrush and the conservation of
regional prairie ecosystems that are expected to continue into the
future.
Summary of Biological Status
To assess golden paintbrush viability, we evaluated the three
conservation biology principles of resiliency, redundancy, and
representation (Shaffer and Stein 2000, pp. 306-310). We assessed the
current resiliency of golden paintbrush sites (Service 2019, pp. 52-63)
by scoring each site's management level, site condition, threats
addressed, site abundance of plants, and site protection, resulting in
a high, moderate, or low condition ranking. One-third of sites were
determined to have a high condition ranking, one-third a moderate
condition ranking, and one-third a low condition ranking (Service 2019,
p. 63). This represents 32 sites in a moderate or higher condition
based on those important factors directly informing resiliency of
individual sites or populations within the SBR (Service 2019, p. 63).
This number of sites exceeds the 15 to 20 populations in stable
condition on protected lands that the recovery criteria identified as
needed to achieve recovery; this therefore provides sufficient
resiliency for the species.
Golden paintbrush sites are well-distributed across the species'
historical range and provide representation across the four geographic
areas within that range (British Columbia, North Puget Sound, South
Puget Sound, and the Willamette Valley). Multiple sites or populations
exist within each of these geographic areas, providing a relatively
secure level of redundancy across the historical range, with the lowest
relative level of redundancy within British Columbia. The resiliency of
the golden paintbrush is variable across the historical range given
differences in site or population abundance, level of management at a
site, and site condition. The best scientific and commercial data
available indicate that the golden paintbrush is composed of multiple
populations, primarily in
[[Page 46102]]
moderate to high condition (Service 2019, p. 63), which are
sufficiently resilient, well-distributed (redundancy and
representation), mostly in protected areas, and managed such that they
will be relatively robust or resilient to any potential cumulative
effects to which they may be exposed.
Summary of Comments and Recommendations
In our June 30, 2021, proposed rule (86 FR 34695), we requested
that all interested parties submit written comments on the proposal by
August 30, 2021. We also contacted appropriate Federal and State
agencies, scientific experts and organizations, and other interested
parties and invited them to comment on the proposed rule. Newspaper
notices inviting general public comment were published in The Oregonian
on July 11, 2021, and the Seattle Times on July 9 through July 13,
2021. We did not receive any requests for a public hearing. All
substantive information provided during the comment period either has
been incorporated directly into this final rule or is addressed below.
Public Comments
We received 10 public comments in response to the proposed rule. We
reviewed all comments we received during the public comment period for
substantive issues and new information regarding the proposed rule.
Eight commenters provided substantive comments or new information
concerning the proposed delisting for golden paintbrush. Below, we
provide a summary of the substantive issues raised in the public
comments we received; however, comments outside the scope of the
proposed rule, and those without supporting information, do not warrant
an explicit response and, thus, are not presented here. Identical or
similar comments have been consolidated into responses based on comment
theme.
(1) Comment: We received multiple comments from WDNR and others
stating that golden paintbrush has not met all the recovery criteria
specified in the recovery plan.
Response: Recovery plans provide roadmaps to species recovery but
are not required in order to achieve recovery of a species, or to
evaluate it for delisting. In addition, recovery plans are also
nonbinding documents that rely on voluntary participation from
landowners, land managers, and other recovery partners. A determination
of whether a valid, extant species should be delisted is made solely on
the question of whether it meets the Act's definitions of an
``endangered species'' or a ``threatened species.'' Recovery criteria
and objectives are developed based on the information known at that
time, and much is learned about a species between the time the recovery
plan is developed and the time we reassess whether it meets the Act's
definition of endangered or threatened. Based on the best available
information, we have determined that golden paintbrush no longer meets
either of these definitions.
(2) Comment: We received several comments from WDNR and others
questioning the metric in recovery criterion 1 to evaluate a stable
population, suggesting it was no longer based on the best available
science and providing examples of populations that have declined. A
comment from WDNR also presented updated information on progress
towards meeting this criterion from 2018-2020.
Response: We updated this final rule to reflect the most up-to-date
progress toward this criterion (see discussion under Criterion 1 for
Delisting, above). As discussed earlier in this document, that
criterion states that to be deemed stable, a population must maintain a
5-year running average population size of at least 1,000 individuals,
where the actual count never falls below 1,000 individuals in any year.
The 2007 5-year review recommended counting only flowering individuals
and incorporating a stable or increasing population trend as based on a
zero or positive overall trend over 5 years (Service 2007, p. 3). While
we did not officially amend or make an addendum to the recovery plan,
we accepted that the most practical way to determine population
abundance was to count flowering plants. The recommendation to evaluate
populations based on stable or increasing trends in abundance was not
formally incorporated into an amended recovery plan. However, in
addition to evaluating progress toward the recovery criteria, we also
evaluated in the SBR (Service 2019, entire) the resiliency, redundancy,
and representation across the species' range in relation to the
potential threats to the species. In the SBR, we evaluated the current
condition of the species at sites using various parameters, including
the level of management, site condition, threats addressed, abundance,
and site protection status. We elicited the advice of experts to
evaluate sites based on these parameters. Populations were also
separately evaluated in the SBR with a site viability index that took
into account population stability and trend. All of this information
was considered when evaluating and making our determination as to
whether delisting is warranted.
Some populations that once maintained higher levels of abundance
have declined, and that abundance can vary markedly across populations
and annually within populations (Fertig 2021, p. 23). Despite this
variability in abundance, the species has sufficient resiliency and
redundancy across its range to maintain viability. In the current
condition analysis of the SBR, 16 sites were ranked as high condition,
with 9 of these sites in Oregon and 7 in Washington. This distribution
of high condition sites across the range of the species contributes to
the redundancy of golden paintbrush. We developed a post-delisting
monitoring plan that will help verify that golden paintbrush remains
secure into the future without the protections of the Act.
(3) Comment: The WDNR stated opposition to the proposed delisting
rule. Despite improvements in species condition from the time of
listing, the WDNR stated that delisting was premature based on concerns
regarding uncertainties related to golden paintbrush's long-term
abundance and viability. The WDNR and other commenters expressed
concern about the funding available for continued management and
monitoring once delisted.
Response: Our review of the best available scientific and
commercial data indicates that the threats to the golden paintbrush
have been eliminated or reduced to the point that the species no longer
meets the definition of an endangered or threatened species under the
Act (see Determination of Golden Paintbrush's Status, below).
Individual sites may experience variability in abundance, and while
some have declined, others have increased in recent years (see Range,
Distribution, Abundance, and Trends of Golden Paintbrush, above).
Despite variability in abundance, the successful establishment of
outplanted golden paintbrush populations, primarily in moderate to high
condition, and mostly in protected areas with management help to
increase the resiliency, redundancy, and representation of the species
and contribute to its viability. For more discussion of golden
paintbrush's population trends and viability, see Range, Distribution,
Abundance, and Trends of Golden Paintbrush Summary of Biological Status
and Threats, and Recovery Criteria, above.
Golden paintbrush is a management-dependent species, and even with
sufficient resources, populations can decline due to various factors.
Although
[[Page 46103]]
the majority of populations are under conservation ownership that
includes management practices to preserve essential characteristics of
golden paintbrush habitat, declines can still occur. Conservation
management will continue in these habitats, but not necessarily to the
same degree at all locations due to variations in capacity, need, or
constraints. As part of the current condition analysis in the SBR, the
management level was assessed for each site based on expert elicitation
and the best available information (see Service 2019, pp. 40-44). This
analysis indicated that the majority of the sites will receive, at
minimum, maintenance to preserve essential characteristics of golden
paintbrush habitat, with several sites operating under long-term
management plans with committed resources for management (see Service
2019, pp. 40-44). The number of and distribution of populations
established across the range contributes to the resiliency and
redundancy of the species, and its ability to maintain sufficient
viability despite some variability in management. Management will also
continue to adapt over time to address future challenges in maintaining
and restoring prairie ecosystems. Funding for some management
activities will likely decline post-delisting as some funding sources
are focused on the recovery of listed species; however, the commitments
of our partners to golden paintbrush conservation, as well as the
number of sites sharing similar habitat and conservation objectives for
other prairie species of concern, will help ensure continued management
of the species into the future. Additionally, our post-delisting
monitoring plan will assess abundance as well as site management and
protection over a minimum 5-year period after delisting.
Regarding continued monitoring by WNHP, golden paintbrush is
currently State-listed as priority 2 in the Washington State Natural
Heritage Plan, and State listing and prioritization is ultimately at
the discretion of the State. Like many State-listed plant species and
other plant species of State concern, we anticipate that the WDNR
through its WNHP and ODA will continue to monitor golden paintbrush in
Washington and Oregon, respectively, although monitoring efforts may
not occur as often as they have in the past.
(4) Comment: Several commenters stated concern over the likelihood
for post-delisting management to continue and be effective. Comments
included site-specific examples such as Forbes Point, American Camp,
Rocky Prairie, and Glacial Heritage where decline in golden paintbrush
abundance due to invasion by exotic grasses or other unknown factors
occurred despite support or management for the species.
Response: As we describe above in our response to Comment (3)
management will also continue to adapt over time to address future
challenges in maintaining and restoring prairie ecosystems and the PDM
plan will assess abundance as well as site management and protection
over a minimum 5-year period after delisting. Please see our response
to Comment (3), above, for a discussion of variation in abundance and
management for the species and our response to Comment (5), below,
about declines in abundance in some populations.
Regarding the site-specific examples provided by commenters, the
Forbes Points and American Camp sites are in low condition, the Rocky
Prairie site is in moderate condition and the Glacial Heritage site is
in high condition based on our current condition analysis in the SBR
which considered management level among other factors that can impact
site condition including habitat condition, threats, abundance, and
site protection status (Service 2019, p. 54).
(5) Comment: We received comments from WDNR and others providing
updated survey data from 2019 and 2020 for outplanted populations,
describing the variable survey effort and an overall decline in
abundance from 2018.
Response: WDNR and others provided updated abundance information
for outplanted populations since 2018, which we considered and
incorporated into this Final Rule (see Range, Distribution, Abundance,
and Trends of Golden Paintbrush, above). As described in their
comments, outplanted populations reached their highest peak to date in
2018 at 562,726 flowering plants and declined to 325,320 plants in
2019. In 2020, there was a reduction of survey effort, and 25
populations in Oregon were not surveyed due to COVID restrictions. If
2019 data were substituted for the 25 populations in Oregon that were
not surveyed in 2020, it is assumed, based on extrapolation, that the
estimated 2020 rangewide abundance would be greater than 370,000 plants
(Fertig 2021, p. 22). Even without the 25 sites that were not monitored
in 2020, the last 4 years of monitoring (2017-2020) represent the 4
years with greatest abundance rangewide. The year 2020 also represents
the second-highest abundance of golden paintbrush in Washington State
at 202,208, which was a 47.8 percent increase from 136,846 in 2019.
Several new outplantings have been initiated since 2018, and we are
continuing to work with our partners to plan new outplantings in Oregon
and Washington. Individual sites may experience variability, and while
some have declined, others have increased in recent years (Service
2019, pp. 27-29; Fertig 2021, pp. 11-29). The species appears to have
sufficient resiliency and redundancy across its range to maintain
sufficient viability, despite variability in abundance.
(6) Comment: We received a comment from WDNR and several other
commenters highlighting concerns over population declines since 2012 in
the populations extant at the time of listing.
Response: At the time of listing in 1997, there were 10 known
golden paintbrush populations in Washington and British Columbia, and
the species was considered extirpated from Oregon. The SBR identified
48 populations established across the range of the species in 2018,
including 26 populations established in Oregon (Service 2019, p. 11).
The ten populations extant at the time of listing make up a small
proportion of the current total abundance of this species established
across its range. While many of the historical populations across the
range of the species were likely extirpated due to land-use changes,
such as development and agriculture, along with encroachment of trees
and other woody plants, the persistence of these ten extant populations
may be due to their protected locations that are not available for
conversion for agriculture or development. Studies suggest that like
other rare species, golden paintbrush may have been eliminated from the
most suitable sites with the remaining extant populations relegated to
marginal sites that did not provide optimal habitat at the time of
listing (Falk et al. 1996, p. 472; Dunwiddie and Martin 2016, p. 12).
Sites with deeper soils and more moisture availability, along with a
more diverse native plant community are more likely to support the
species (Dunwiddie and Martin 2016, entire), and successful
reintroduction to prairies in former agriculture lands with deeper
soils have had great success (Delvin 2013, p. 7). Thirty-seven
outplanted populations of golden paintbrush have been established and
represent the majority of the abundance of the species across its
historical range, including 26 populations in Oregon where the species
was previously extirpated. These outplanted populations help to
increase the resiliency, redundancy, and representation of the species
and contribute to its viability. While the 10 sites extant at the time
of listing remain
[[Page 46104]]
and continue to contribute to the species' recovery, these sites likely
do not represent the ideal site characteristics for the species.
Although the 10 populations at the time of listing have exhibited
decline, the efforts at outplanted sites across the range represent the
recovery of golden paintbrush. For more information, see the discussion
above on populations extant at the time of listing under Range,
Distribution, Abundance, and Trends of Golden Paintbrush.
(7) Comment: We received several comments addressing the
difficulties of establishing new populations, and highlighting the
variability in seeding success, even on sites with established
populations.
Response: We identified the difficulties in establishing new
populations and the variability in seeding success in the SBR for
golden paintbrush (Service 2019, p. 51) and took this into account in
our determination. It is not uncommon to have failed reintroduction or
introduction attempts for any species. For golden paintbrush, despite
some outplanting failures, outplanted populations have been largely
successful and represent the majority of the abundance of golden
paintbrush across the range. Furthermore, in Oregon, where the species
was previously extirpated, 26 populations have been established due to
outplanting. Golden paintbrush continues to be outplanted by our
partners at other conservation sites with the expectation of
establishing even more populations across the species' range in the
future.
(8) Comment: The WDNR and several other commenters disagreed that
direct seeded populations may initially undergo a period of rapid
growth followed by a period of decline to a more stabilized number. The
commenters stated that it is unknown if population stabilization will
occur.
Response: While there may be an initial period of rapid growth
following an establishment period, population trends following a peak
appear to vary greatly by site (Fertig 2021 pp. 24-27). After some
large declines, several sites rangewide increased from 2019 to 2020,
although not to the level of the initial spike in abundance. While some
populations show a boom-bust population trend as was documented at some
outplanted sites in Oregon (Kaye 2019, pp. 26-27), not all populations
across the range are experiencing consistent decline. Rangewide
abundance from 2017-2020 represent the four greatest abundances across
all of the years monitored, including 25 sites that were not monitored
in Oregon in 2020 (Fertig 2021, p. 22). As some commenters mentioned,
the addition of seed to some of these populations complicates the
assessment of population trends over time. Furthermore, population
variability seen following the initial peak could be attributed to
other impacts to the species from other stressors such as drought,
herbivory, or competition from invasive species at the site level.
Taken together, we find that the available information supports that
while golden paintbrush populations may peak in abundance following
initial establishment and may decline to lower levels, the pattern does
not suggest a species-level decline overall rangewide. We will continue
to monitor populations over 5 years using the post-delisting monitoring
plan, which will contribute data and increase our understanding of
population dynamics and persistence over those years.
(9) Comment: The WDNR commented that there was no mention of the
viability index developed by Dr. Tom Kaye for golden paintbrush in the
proposed rule. In addition to providing us with 2019 and 2020 golden
paintbrush survey data and their updated viability index for the
species, the WDNR stated that as of 2020, 9 of 52 populations had a
viability index score of 3, indicative of populations with positive
growth over time, relatively stable numbers, and greater than 1,000
flowering individuals averaged over 5 years.
Response: The Service considered the viability index developed by
Dr. Tom Kaye and summarized this information in the SBR which provides
the best available information to inform our listing decision under the
Act. In addition, in response to the information submitted by the WDNR,
we re-calculated the viability index with data that include the most-
recent survey year (either 2019 or 2020), since many sites were not
surveyed in 2020. This resulted in 10 out of 46 populations having a
score of three, an increase from the 6 out of 43 populations with a
score of 3 identified in the SBR, indicating there are now more
populations with high viability than what we identified in 2018. As we
mentioned in the SBR, indices of this type are useful for synthesizing
several pieces of information, but they can simplify or oversimplify
available information. This index was intended to provide a broad
evaluation of the species' population size and stability, and while
these data were taken into consideration, they were considered along
with the current condition analysis in the SBR. Additionally, we used
updated survey data to evaluate the status relative to the recovery
criteria (see Recovery Criteria, above).
(10) Comment: We received several comments (from WDNR and others)
expressing concern over potential impacts of climate change on the
species. We also received several comments from WDNR and others
highlighting WDNR's 2019 report updating an earlier climate change
vulnerability assessment of golden paintbrush.
Response: In this final rule, we have incorporated the new
information from the climate change vulnerability assessment
(Kleinknecht et al. 2019, entire) and have added to our discussion on
climate change. The Service reviews the best scientific and commercial
information available when conducting a threats analysis. In
considering what factors might constitute a threat, we look beyond the
mere exposure of the species to the factor to determine whether the
exposure causes actual impacts to the species. The mere identification
of factors that could impact a species negatively is not sufficient to
compel a finding that listing (or maintaining a currently listed
species) on the Federal Lists of Endangered or Threatened Wildlife and
Plants is appropriate. In determining whether a species meets the
definition of a threatened or endangered species, we must evaluate all
identified threats by considering the species' expected response and
the effects of the threats--in light of those actions and conditions
that will ameliorate the threats--on an individual, population, and
species level, as well as the cumulative effect of the threats.
Drought, particularly in the spring and summer, likely impacts
golden paintbrush populations, with potentially larger impacts on
populations with low viability. Research conducted on microsite needs
for the species suggested that deeper soils with high richness of
native perennial forbs were more likely to support the species
(Dunwiddie and Martin 2016, entire). Establishing populations can be
difficult, particularly with annual variability in climate and drought
seen in recent years, and as a result, multiple outplantings have
failed. Despite this, seven new outplantings have been initiated since
2018 in Washington, including one on Protection Island. While it is
difficult to assess the success of these outplantings due to variable
monitoring efforts in recent years, two have been noted as likely
unsuccessful due to presence of nonnative weedy
[[Page 46105]]
annuals, but the others show promise (Martin 2021, pp. 10, 23-25).
On a rangewide scale, the species demonstrates sufficient
resiliency and representation to adapt to projected changes in climate.
We have established 17 populations with a 5-year average of greater
than 1,000 individuals over the species' range from British Columbia to
Oregon, on sites representing environmental diversity consisting of wet
and dry prairie, and valley foothills (Kaye 2019, p. 10). Total
abundance was greater than 325,320 flowering plants across the range in
2019, and 288,699 in 2020 (excluding 25 populations that were not
surveyed due to COVID restrictions); substituting 2019 data for
populations not surveyed in 2020 yields an estimated abundance of
greater than 370,000 flowering plants rangewide (Fertig 2021, p. 22).
Despite drought seen in recent years, abundance of populations extant
at the time of listing increased in 2020, and Washington populations
reached their second-highest total abundance of 202,208 flowering
plants, a 47.8 percent increase from 2019 (Fertig 2021, p. 11). Despite
evidence of the potential effects of drought on golden paintbrush
abundance in recent years (see Fertig 2021, p. 30; Martin 2021, p. 6),
periods of drought have not been documented to consistently impact
abundance across populations.
Regional climate change literature suggests that prairie ecosystems
were established under warmer and drier conditions and are unlikely to
be disadvantaged from future increased summer drought (Bachelet et al.
2011, p. 417). Golden paintbrush populations can experience high
variability in abundance between years (Fertig 2021, pp. 24-27), and
while climate change is a stressor, given the species' high abundance
and distribution across the range from British Columbia to Oregon,
golden paintbrush should have sufficient resiliency and redundancy to
remain viable into the future. Establishing plant species such as the
golden paintbrush to populate the full geographic and climatic range of
Pacific Northwest prairies has been identified as a ``climate-smart''
strategy (Bachelet et al. 2011, p. 420). The post-delisting monitoring
plan will facilitate the evaluation of the species beyond delisting and
detect unanticipated levels and/or extent of declines in abundance.
Since the publication of the proposed rule (86 FR 34695; June 30,
2021), we received an updated climate change vulnerability index (CCVI)
report from our State partners at the WDNR's Washington Natural
Heritage Program (Kleinknecht et al. 2019, entire). This report was
provided as a comment from WDNR. We evaluated the report and compared
it to a similar assessment that was conducted in 2014 (Gamon 2014,
entire). The CCVI was conducted using a NatureServe protocol, which
relies on a species' natural history, distribution, and landscape to
inform whether and to what degree it will be impacted by climate change
(Young et al. 2016, entire). In the 2019 report, golden paintbrush was
ranked as ``Highly Vulnerable'' to climate change, a change from the
2014 report which ranked it as ``Presumed Stable'' (Kleinknecht et al.
2019, entire; Gamon 2014, entire).
While this 2019 CCVI report has helped inform our decision, it does
not change our final determination. The 2019 assessment looked only at
a small proportion of the species' range. It assessed only a subset of
sites from Washington, based on 22 native occurrences (11 extant and 11
extirpated or historical), not including the 10 outplanted sites in
Washington or any of the populations in Oregon. The distribution of
points used in the assessment were primarily in North Puget Sound, and
given that half of these represent sites that have already undergone
extirpation, this report is not necessarily representative of the
potential impact on golden paintbrush across its currently occupied
range.
Additionally, the guidelines for the CCVI describe that it works
best for the scale from the size of a National Park to a State, and at
larger scales may mask the vulnerability of local populations to
climate change (Young et al. 2016, p. 9). Based on the larger scale of
golden paintbrush's range, from Oregon to British Columbia, the CCVI
method is not likely to be appropriate to assess climate change
vulnerability.
(11) Comment: We received a comment from WDNR and several others
expressing concern about the impacts of herbivory on golden
paintbrush's viability. Commenters provided examples of impacts at
specific sites, the difficulties in managing herbivory, and the
potential impacts to seed production.
Response: Herbivory was noted as a threat at the time of listing in
1997, especially due to the limited number (10) of extant populations.
Despite having a potential impact on abundance, a total of 48 golden
paintbrush populations are now represented across the species' range in
a variety of habitats and constitute a large geographic distribution
contributing to the species' resiliency and redundancy, and to the
species' ability to withstand stochastic events, including herbivory.
Active, targeted management may be important in curtailing significant
impacts, but it is not likely to occur across all sites at the same
level, and it is not intended to result in the complete elimination of
herbivory impacts on this species. Despite the recent examples of
herbivory provided in the comments and anecdotal observations for
specific sites and years, there are no consistent data linking
herbivory to population declines, especially at the rangewide scale.
Herbivory can vary by site, year, frequency, and level of impacts.
Populations of the species will likely retain moderate to high levels
of viability given the species' established redundancy across its range
and the suitable condition of the habitat despite variable herbivory
impacts; however, the post-delisting monitoring plan is designed to
help track site-specific management and potential impacts to species
abundance for at least 5 years following delisting. For more
information, please see the discussion of herbivory under Summary of
Biological Status and Threats, above.
(12) Comment: We received a comment from WDNR and others expressing
concern over potential impacts of hybridization to golden paintbrush,
as well as expressing concern that the hybridization strategy and
guidance document was not available for review during the June 30,
2021, proposed rule's public comment period.
Response: Hybridization is a potential threat to golden paintbrush
that must continue to be managed, and we continue to work
collaboratively with our partners to find solutions and management for
sites that are already impacted by hybridization. Although a public
commenter noted two sites on Whidbey Island as having potential
hybridization impacts given a previous experimental study that seeded
both paintbrush species, given low recruitment of harsh paintbrush at
these sites, hybridization has never been identified by experts as a
concern in those sites.
While the details of the hybridization strategy and guidance were
not available during the June 30, 2021, proposed rule's public comment
period, when the document was finalized, we organized a public roll-out
where we presented details of the hybridization strategy and guidance,
answered questions, and highlighted to our conservation partners that
comments would be accepted to inform the next iteration of the document
to make further improvements to the strategy. The document was posted
on our website, and no comments were received.
[[Page 46106]]
Solutions presented in the hybridization strategy and guidance document
include, but are not limited to, preventing hybridization in other
geographic areas, implementing a decision-making framework for new
sites under consideration for paintbrush plantings, actively managing
sites that are hybridized, and mapping the distribution of both golden
and harsh paintbrush. Through the MOU and hybridization strategy and
guidance document, we and our State agency partners are committed to
managing hybridization and working collaboratively with our other
prairie conservation partners to ensure this potential threat is
adequately managed after the delisting of golden paintbrush.
(13) Comment: We received a comment from WDNR and several others
noting the lack of seed production at some populations in recent years
(2019-2021), emphasizing the potential for declines given the species'
short-lived seed bank and the species' reliance on bumble bees for
pollination.
Response: Although we agree with the need to track and better
understand the magnitude and extent of possible impacts of reduced seed
production, based on the best available information, the observed
reduced seed production at some sites does not appear to be resulting
in notable demographic changes impacting the resiliency of golden
paintbrush populations. Any decline in seed production could negatively
impact a golden paintbrush population given its short-lived seedbank,
and there are many unknowns associated with the potential effects of
climate change on both golden paintbrush and pollinator communities. To
date, however, there are uncertainties regarding the frequency,
distribution, and scale of the lack of seed production, and uncertainty
whether these represent short-term, isolated events or a large-scale
change. Likewise, while golden paintbrush is reliant on bumble bees as
its primary pollinator, it is unknown if pollinator decline is
occurring across the range of golden paintbrush. Two bumble bees
identified at the species level in the SBR, Bombus vosnesenskii and B.
bifarius, were assessed as stable in the Pacific Northwest, and one
bumble bee, B. californicus (sometimes recognized as B. fervidus), is
less common in the Pacific Northwest than historically (Hatfield et al.
2021, pp. 15, 32, 72-73). However, the status and trends of these and
other pollinators have not been evaluated in golden paintbrush
populations. These anecdotal observations present important
information, yet it remains unclear how they translate to trends in
population abundance over time and the scope of the impact across the
species' range. We do not have information to conclude that these
concerns are impacting the species to a degree that would result in the
species meeting the Act's definition of either an endangered species or
a threatened species. Post-delisting monitoring will enable us to
monitor population abundance for at least 5 years after the species has
been delisted.
(14) Comment: We received a comment from WDNR and several others
expressing concern over the number of small populations (fewer than 100
individuals) and the small size of habitat occupied by golden
paintbrush at some sites (less than 1 acre), suggesting that small
populations and small patches of habitat should be eliminated from
consideration regarding contribution towards recovery.
Response: We describe in the SBR that larger sites are likely
better for population viability, as they allow for the development of
larger populations and greater genetic diversity (Service 2019, pp. 35-
36); however, there is no basis to remove populations existing on less
than 1 acre or those with abundance of fewer than 100 individuals from
our assessment of sites contributing to recovery. While small
populations may inherently have a greater relative risk of extirpation
than larger populations, that does not mean they cannot or do not
contribute to species recovery. Site abundance is an important
consideration with regard to the potential for the species to persist
over time, and we used site abundance as part of our analysis of
current condition in the SBR (Service 2019, p. 27). These data were
incorporated into a population viability index as well as an assessment
of current condition, which were both considered when evaluating
whether the species needs protections under the Act. Habitat patch size
was discussed in the SBR (Service 2019, pp. 35-38), and as noted, there
are uncertainties regarding the importance of habitat patch size for
populations of golden paintbrush. The number of sites with more than
1,000 individuals and the wide distribution across the species'
historical range will likely provide sufficient resiliency and
redundancy to protect the species from stochastic events.
(15) Comment: We received multiple comments disagreeing with our
evaluation of progress toward recovery criterion 2 and our assessment
of the level of protection based on land ownership.
Response: In this final rule, we note that this criterion was not
precisely met as stated in the recovery plan (see Criterion 2 for
Delisting, above). However, a significantly greater number of
populations under conservation-focused ownership provide protection to
either the species or its habitat compared to the minimum number
identified in the criterion; this will help the species retain
sufficient viability into the future. Forty-five of the 48 golden
paintbrush populations are in either public ownership; are owned by a
conservation-oriented, nongovernmental organization; or are under
conservation easement (Service 2019, p. 62). This number is much higher
than the number (15) required to provide protection in the recovery
plan's criterion 2. Such ownership is expected to protect sites from
development and land use that would have long-term, wide-ranging
deleterious effects on this species. Prairies are management-dependent
habitats, and while habitat management will likely continue to occur
across the majority of the sites, it will not necessarily occur to the
same degree due to variations in capacity, need, or constraints across
sites. We have developed a post-delisting monitoring plan to monitor
abundance, site management, and the protection status of populations
over at least 5 years following delisting.
(16) Comment: We received multiple comments expressing concern
regarding the potential of recovery sites being shared between golden
paintbrush and Taylor's checkerspot butterfly, given the threat of
hybridization between golden paintbrush and harsh paintbrush, the
latter a common host plant for Taylor's checkerspot butterfly.
Response: Sites that support Taylor's checkerspot butterfly with
harsh paintbrush will not be available to support golden paintbrush.
However, there may be opportunities for Taylor's checkerspot butterfly
and golden paintbrush to share sites, particularly if other hosts
plants (in addition to golden paintbrush) are used, including English
plantain (Plantago lanceolata). Likewise, sites in Oregon that have
golden paintbrush and other host plants do support populations of
Taylor's checkerspot butterfly. In this final rule, we address the fact
that hybridization with harsh paintbrush has led to the abandonment of
three recovery sites for golden paintbrush. Hybridization is a serious
potential threat, and we have entered into an MOU concerning
hybridization with our State partners (WDFW and WDNR) and created a
hybridization strategy and guidance
[[Page 46107]]
document to ensure the threat of hybridization with harsh paintbrush is
managed and coordinated between partners into the future.
(17) Comment: We received several comments providing information on
recent difficulties with seed availability at some sites, the potential
impacts to nursery seed production, and challenges with seed
production.
Response: These observations are concerning given the short-lived
seedbank of the species; however, it remains unclear if the local,
episodic events (due to herbivory or drought) represent a new long-term
scenario with consistent impacts across the range of the species. Our
post-delisting monitoring plan will direct efforts to track populations
to help determine if these observations continue and whether or not
there are broader impacts to golden paintbrush.
If populations of golden paintbrush decline below a certain
threshold, seed collection from certain sites could prove difficult or
inadvisable, and seed production for this species could be affected.
Seed production efforts might need to be supplemented by some
outplanted populations that originated from the populations extant at
the time of listing and could incorporate increased genetic diversity
into nursery production (St. Clair et al. 2020, pp. 587-590). While a
comment highlighted past difficulties in seed production for the
species at a seed farm in Washington, seed production efforts across
the range have been sufficient to support numerous outplantings that
have contributed to the recovery of the species across its range.
Currently, there are seed production programs at the Center for Natural
Lands Management, along with smaller scale operations in North Puget
Sound representing seed collected from the populations extant at the
time of listing on Whidbey Island, the San Juan Islands, and South
Puget Sound. New mixed-source beds for golden paintbrush have been
recently established at the Center for Natural Lands Management and the
Pacific Rim Institute, and we will continue to work with our partners
to ensure that seed sources for this species remain available as long
as considered necessary. These combined seed production efforts will
continue to support ongoing establishment of new populations and
augmentation of existing populations throughout the range of the
species.
(18) Comment: We received a few comments describing historical
habitat loss of Pacific Northwest prairies. We also received a comment
discussing the importance of these rare habitats to Tribes from a
public commenter unaffiliated with any Tribe.
Response: The rarity of prairies on the landscape presents
challenges to conservation of prairie-dependent species, including
golden paintbrush. Pacific Northwest prairies have experienced
significant declines from their historical distribution due to habitat
loss from development and agriculture, as well as changes in
disturbance regimes and the maintenance provided by indigenous Tribes
for thousands of years. While these comments were not submitted by a
Tribe, we know the success of prairie-dependent species conservation is
tied directly to the habitats that support the species and to the
extensive network of partners, including Tribes, working to restore and
maintain prairies across the species' range;. These partnerships will
continue to focus on restoration and maintenance of golden paintbrush
and other species that rely on these rare prairie communities into the
future. For more information, please see the discussion of habitat loss
under Summary of Biological Status and Threats, above.
(19) Comment: We received a comment that disagrees with the
information presented on genetic diversity in the June 30, 2021,
proposed rule, stating that golden paintbrush has reduced genetic
diversity because seed used to establish populations was sourced from
seed from the populations extant at the time of listing.
Response: Genetic studies have indicated that despite its limited
geographic range and isolation of its populations, golden paintbrush
has high levels of diversity (Godt et al. 2005, p. 87; Lawrence and
Kaye 2011, p. 173). Additionally, a recent study indicates that genetic
diversity has increased in reintroduced populations relative to extant
populations as a result of multiple source populations propagated
together in a nursery production setting (St. Clair et al. 2020, pp.
589-591). Establishing populations across the species' range and in a
variety of ecological settings will further contribute to the genetic
diversity and representation of the species.
(20) Comment: We received a comment disagreeing with the
established methodology of counting flowering plants to determine
abundance estimates, The commenter stated that survey information could
be unreliable due to the lack of non-flowering plant information.
Response: We developed the abundance estimate methodology in
coordination with the golden paintbrush technical team to provide a
consistent and reliable measure of adult plant abundance within
populations to track population status (Service 2007, p. 3). We and the
technical team determined it was impractical to count non-flowering
golden paintbrush plants, and recommended modifying Recovery Criterion
1 to specify a flowering plant metric (Service 2007, p. 3). Although
counting flowering plants could mean that populations might actually be
undercounted, because vegetative plants are not counted, flowering
plant abundance better informs the number of individuals most likely to
reproductively contribute to the population, and may also be the best
method to estimate a reasonable minimum population size.
(21) Comment: We received multiple comments highlighting potential
impacts on the golden paintbrush and its habitat from invasive plant
species given projected warmer temperatures.
Response: Habitat loss has been considered a threat to the species
since the time of listing (1997), and part of that consideration is
focused on invasive species. While invasive species will always be a
potential threat that will need adequate management, given the ongoing
invasive species management commitments across the species' range,
golden paintbrush is expected to maintain moderate to high viability.
Many of the exotic species in the Pacific Northwest have wide
distributions and are likely adaptable to climate change (Bachelet et
al. 2011, p. 417). As commenters mentioned, there are ongoing studies
focused on how to manage Vulpia ssp. (a winter annual grass) in South
Puget Sound prairie communities that will provide valuable information
on how to control this nonnative species within golden paintbrush
habitat across its range. Management techniques are constantly evolving
as new challenges arise from invasive species, climate change, and
unforeseen circumstances. This progression in management will likely
continue into the future; however, the level of success is not always
certain. We developed a post-delisting monitoring plan to track
population status, site-specific management actions, and the presence
of invasive species that will continue for at least 5 years following
delisting.
(22) Comment: We received multiple comments expressing concern over
the adequacy of the post-delisting monitoring plan to track the
species' condition over the 5-year timeframe. The commenters suggest
that estimating population size into categories (more than 1,000
flowering plants and more than 10,000 flowering plants) would be
[[Page 46108]]
inadequate to detect changes in size and population trend and reduces
the ability to understand why changes are occurring.
Response: The population size categories referenced in the post-
delisting monitoring plan are not meant to be a population target but
rather a threshold at which to review significance, methods, and
potential threats with States and other collaborators before numbers
might fall below the recovery objective. These thresholds are also
consistent with those used in the SBR current condition analysis.
Following delisting, the Act requires us to monitor effectively for not
less than 5 years the status of the species in cooperation with the
States that are within the range of the species (16 U.S.C. 1533(g)(1)).
We developed a draft post-delisting monitoring plan for the golden
paintbrush, coordinated review of the plan with State agencies in
Washington and Oregon, and made the draft plan available for public
review and comment. Sustaining post-delisting monitoring efforts can be
challenging and subject to competing priorities for available
resources. Nonetheless, we designed the post-delisting monitoring
assuming limited resources. We are coordinating with State agencies in
Washington and Oregon to find funding to support post-delisting
monitoring efforts, but we fully anticipate some of the conservation
landowners will continue to monitor populations on their own because of
their ongoing interest in and commitment to conserving this species and
others. We will continue to work with our conservation partners to
ensure implementation of an effective and feasible post-delisting
monitoring plan for the golden paintbrush.
Determination of Golden Paintbrush'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 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.
Status Throughout All of Its Range
After evaluating threats to the species and assessing the
cumulative effect of the threats under the Act's section 4(a)(1)
factors, we find, based on the best available information, and as
described in our analysis above, stressors identified at the time of
listing and several additional potential stressors analyzed for this
assessment do not affect golden paintbrush to a degree that causes it
to be in danger of extinction either now or in the foreseeable future.
Development of property for commercial, residential, and agricultural
use (Factor A) has not occurred to the extent anticipated at the time
of listing and is adequately managed; existing information indicates
this condition is unlikely to change in the foreseeable future.
Potential constriction of habitat for expansion and refugia (Factor A)
also has not occurred to the extent anticipated at the time of listing,
and existing information indicates this condition is unlikely to change
in the foreseeable future. Habitat modification through succession of
prairie and grassland habitats to shrub and forest lands (Factor A) is
adequately managed, and existing information indicates this condition
is unlikely to change in the foreseeable future. Recreational picking
and associated trampling (Factor B) has not occurred to the extent
anticipated at the time of listing; the species appears to tolerate
current levels of this activity, and existing information indicates
that this condition is unlikely to change in the foreseeable future.
Herbivory on plants and seeds (Factor C) has not occurred to the extent
anticipated at the time of listing; the species appears to tolerate
current levels of herbivory, and existing information indicates that
this condition is unlikely to change in the foreseeable future.
Hybridization with the harsh paintbrush (Factor E) is adequately
managed, and existing information indicates this condition is unlikely
to change in the foreseeable future. Finally, golden paintbrush appears
to adequately tolerate the effects of climate change (Factor E), and
existing information indicates that this tolerance is unlikely to
substantially change in the foreseeable future. In addition, there are
means to help further mitigate for those effects of climate change
(e.g., continued outplanting across varied site conditions). The
existing regulatory mechanisms (Factor D) are sufficient to ensure
protection of the species at the reduced levels of threat that remain.
Thus, after assessing the best available information, we determine
that golden paintbrush is not in danger of extinction, nor likely to
become so in the foreseeable future, throughout all of its range.
Status Throughout a Significant Portion of Its Range
Under the Act and our implementing regulations, a species may
warrant listing if it is in danger of extinction or likely to become so
in the foreseeable future throughout all or a significant portion of
its range. Having determined that the golden paintbrush 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 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 golden paintbrush, we choose
to evaluate the status question first. We began by identifying portions
of the range where the biological status of the species may be
different from its biological status elsewhere in its range. For this
purpose, we considered information pertaining to the geographic
distribution of (a) individuals of the species, (b) the threats that
the species faces, and (c) the resiliency condition of populations.
For the golden paintbrush, we considered whether the threats or
their effects on the species are greater in any biologically meaningful
portion of the species' range such that the species is in danger of
extinction now or likely to become so in the foreseeable future in that
portion. We examined the following threats: (1) Habitat succession of
prairie and grassland habitats to shrub and forest due to fire
suppression, interspecific competition, and invasive species; (2)
development of property for
[[Page 46109]]
commercial, residential, and agricultural use; (3) low potential for
expansion and refugia due to constriction of habitat by surrounding
development or land use; (4) recreational picking (including associated
trampling); (5) herbivory (on plants and seeds); (6) hybridization with
harsh paintbrush; and (7) the effects of climate change, including
cumulative effects. Although the impact of hybridization with the harsh
paintbrush is most evident in the South Puget Sound region of the
species' range, this impact was due to the unintended consequences of
seeding harsh paintbrush in aid of another species, so as a potential
stressor, it is being addressed throughout the species' range with the
hybridization strategy and guidance. We found no biologically
meaningful portion of the golden paintbrush' range where threats are
impacting individuals differently from how they are affecting the
species elsewhere in its range, or where the condition of the species
differs from its condition elsewhere in its range such that the status
of the species in that portion differs from its status in any other
portion of the species' range.
Therefore, we find that the species is not in danger of extinction
now or likely to become so in the foreseeable future in any significant
portion of its range. This does not conflict with the courts' holdings
in Desert Survivors v. Department of the Interior, 336 F. Supp. 3d 1131
(N.D. Cal. 2018), and Center for Biological Diversity v. Jewell, 248 F.
Supp. 3d. 946, 959 (D. Ariz. 2017) because, in reaching this
conclusion, we did not apply the aspects of the Final Policy on
Interpretation of the Phrase ``Significant Portion of Its Range'' in
the Endangered Species Act's Definitions of ``Endangered Species'' and
``Threatened Species'' (79 FR 37578; July 1, 2014), including the
definition of ``significant'' that those court decisions held to be
invalid.
Determination of Status
Our review of the best available scientific and commercial
information indicates that the golden paintbrush does not meet the
definition of an endangered species or a threatened species in
accordance with sections 3(6) and 3(20) of the Act. Therefore, we
remove the golden paintbrush from the List of Endangered and Threatened
Plants.
Effects of the Rule
This final rule revises 50 CFR 17.12(h) by removing the golden
paintbrush from the List of Endangered and Threatened Plants. On the
effective date of this rule (see DATES, above), the prohibitions and
conservation measures provided by the Act, particularly through
sections 7 and 9, no longer apply to the golden paintbrush. Federal
agencies will not be required to consult with the Service under section
7 of the Act in the event that activities they authorize, fund, or
carry out may affect the golden paintbrush. There is no critical
habitat designated for this species, so there is no effect to 50 CFR
17.96.
Post-Delisting Monitoring
Section 4(g)(1) of the Act requires us, in cooperation with the
States, to implement a system to monitor effectively, for not less than
5 years, all species that have been recovered and delisted. Post-
delisting monitoring (PDM) refers to activities undertaken to verify
that a species delisted due to recovery remains secure from the risk of
extinction after the protections of the Act no longer apply. The
primary goal of PDM is to monitor the species to ensure that its status
does not deteriorate, and if a decline is detected, to take measures to
halt the decline so that proposing it as endangered or threatened again
is not needed. The monitoring is designed to detect the failure of any
delisted species to sustain itself without the protective measures
provided by the Act. If, at any time during the monitoring period, data
indicate that the protective status under the Act should be reinstated,
we can initiate listing procedures, including, if appropriate,
emergency listing under section 4(b)(7) of the Act. Section 4(g) of the
Act explicitly requires us to cooperate with the States in development
and implementation of post-delisting monitoring programs, but we remain
responsible for compliance with section 4(g) and, therefore, must
remain actively engaged in all phases of post-delisting monitoring. We
also seek active participation of other entities that are expected to
assume responsibilities for the species' conservation post-delisting.
We prepared a PDM plan that describes the methods for monitoring
the species after its delisting. Monitoring of flowering plants at each
golden paintbrush site extant in 2018 will take place every other year,
over a minimum of 5 years, beginning the first spring after the
effective date of this final delisting rule (see DATES, above).
Monitoring efforts will be slightly modified from prior protocols, by
only requiring a visual estimation of population size when the
population clearly exceeds 1,000 flowering individuals but is fewer
than 10,000, or when a population clearly exceeds 10,000 flowering
individuals as opposed to an actual count or calculated estimate of
flowering plants. This modification should streamline monitoring
efforts. It is our intent to work with our partners to maintain the
recovered status of golden paintbrush. The final PDM plan can be found
at https://www.regulations.gov under Docket No. FWS-R1-ES-2020-0060.
Required Determinations
National Environmental Policy Act
It is our position that, outside the jurisdiction of the U.S. Court
of Appeals for the Tenth Circuit, environmental analyses pursuant to
the National Environmental Policy Act of 1969 (NEPA; 42 U.S.C. 4321 et
seq.) need not be prepared in connection with determining a species'
listing status under the Endangered Species 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 acknowledge our responsibility to
communicate meaningfully with recognized Federal Tribes on a
government-to-government basis. In accordance with Secretary's Order
3206 of June 5, 1997 (American Indian Tribal Rights, Federal-Tribal
Trust Responsibilities, and the Endangered Species Act), we 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 Native American culture, and to make information available
to Tribes.
We do not believe that any Tribes will be affected by this rule,
and we did not receive any comments on our June 30, 2021, proposed rule
from a Tribe. There are currently no golden paintbrush sites on Tribal
lands, although some sites may lie within the usual and accustomed
places for Tribal collection and gathering of resources.
