Endangered and Threatened Wildlife and Plants; Withdrawal of the 
Proposed Rules To List Graham's Beardtongue (Penstemon grahamii) and 
White River Beardtongue (Penstemon scariosus var. albifluvis) as 
Threatened Species and To Designate Critical Habitat

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Proposed rule; withdrawal.

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

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), are 
withdrawing our August 6, 2013, proposed rules to list Graham's 
beardtongue (Penstemon grahamii) and White River beardtongue (Penstemon 
scariosus var. albifluvis) as threatened species throughout their 
ranges and to designate critical habitat for these two plant species 
under the Endangered Species Act of 1973, as amended (Act). These 
withdrawals are based on our conclusion that the stressors affecting 
the species as identified in the proposed listing rule are not as 
significant as previously understood at the time of publication of that 
proposed rule, such that the species do not meet the Act's definition 
of an ``endangered species'' or of a ``threatened species.'' Our 
conclusion is informed by an updated analysis of new and previous 
information concerning current and future stressors to the species and 
conservation efforts for them.

DATES: The U.S. Fish and Wildlife Service is withdrawing proposed rules 
published on August 6, 2013 (78 FR 47590 and 47832), as of January 13, 
2022.

ADDRESSES: Relevant documents used in the preparation of this 
withdrawal are available on the internet at https://www.regulations.gov 
at Docket No. FWS-R6-ES-2019-0029.

Executive Summary

    Why we need to publish this document. Under the Act, a species may 
warrant protection through listing if it is endangered or threatened 
throughout all or a significant portion of its range. In 2013, we 
issued proposed rules to list the Graham's beardtongue and White River 
beardtongue (beardtongues) and to designate critical habitat for the 
beardtongues. This document withdraws the proposed listing rule because 
we have now determined that the factors affecting the beardtongues as 
identified in that proposed rule are not as significant as previously 
understood in 2013, such that listing is not warranted for these 
species. Because we are withdrawing the proposed listing rule for the 
beardtongues, we also withdraw the proposed critical habitat 
designation for these species.
    The basis for our action. 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. Under the Act, we may determine that a species is an endangered 
or threatened species because of any of five factors: (A) The present 
or threatened destruction, modification, or curtailment of its habitat 
or range; (B) overutilization for commercial, recreational, scientific, 
or educational purposes; (C) disease or predation; (D) the inadequacy 
of existing regulatory mechanisms; or (E) other natural or manmade 
factors affecting its continued existence (16 U.S.C. 1533(a)(1)). We 
have determined that the stressors affecting the beardtongues as 
identified in the proposed listing rule (energy development, cumulative 
impacts from livestock grazing, invasive weeds, small population size, 
and climate change) are not as significant as previously understood at 
the time of publication of the proposed rule (i.e., in 2013).

Previous Federal Actions

    On August 6, 2013, we published a proposed rule to list Graham's 
beardtongue and White River beardtongue as threatened species (78 FR 
47590) under the Act (16 U.S.C. 1531 et seq.). Please refer to that 
proposed rule for a detailed description of previous Federal actions 
concerning Graham's beardtongue and White River beardtongue prior to 
2013. On August 6, 2013, we also published a proposed rule to designate 
critical habitat for both species (78 FR 47832). Following publication 
of our August 6, 2013, proposed rules, the same parties (Bureau of Land 
Management (BLM); U.S. Fish and Wildlife Service (Service); Utah 
Department of Natural Resources (DNR); State of Utah School and 
Institutional Trust Lands Administration (SITLA); Uintah County, Utah) 
that had drafted a 2007 conservation agreement (CA) for Graham's 
beardtongue and White River beardtongue reconvened to evaluate species' 
surveys and distribution information and to reassess the conservation 
needs of both Graham's and White River beardtongues. Based on this 
evaluation, the parties completed a new conservation agreement (2014 
CA, entire) that specifically addressed the threats identified in our 
August 6, 2013, proposed listing rule (78 FR 47590). Additional 
signatories to the 2014 CA included the Utah Public Lands Policy 
Coordination Office (PLPCO) and Rio Blanco County, Colorado. While 
private landowners were not signatories to the 2014 CA, some private 
lands are designated as conservation areas under the 2014 CA, and 
Uintah County coordinates with and represents the interests of affected 
landowners.
    In the 2014 CA, the parties committed to conservation actions 
including establishing 44,373 acres (ac) (17,957 hectares (ha)) of 
occupied and unoccupied suitable habitat as protected conservation 
areas with limited surface disturbance and avoidance of Graham's and 
White River beardtongue plants by 300 feet (ft) (91.4 meters (m)). 
Additionally, BLM agreed to avoid surface disturbances within 300 ft 
(91.4 m) of Graham's and White River beardtongue plants within and 
outside of conservation areas on BLM land. The parties also developed 
conservation measures to address the cumulative impacts from livestock 
grazing, invasive weeds, small population size, and climate change by 
continuing species monitoring, monitoring climate, reducing impacts 
from grazing when and where detected, and controlling invasive weeds.
    On May 6, 2014, we announced the reopening of the public comment 
period on our August 6, 2013, proposed listing and proposed designation 
of critical habitat rules until July 7, 2014 (79 FR 25806). In that 
document, we also announced the availability of a draft economic 
analysis (DEA), draft environmental assessment (EA), draft 2014 CA, and 
amended required determinations section of the critical habitat 
proposal. We also announced the availability of 2013 survey results for 
Graham's and White River beardtongue plants and our intent to hold a 
public information meeting and public hearing.
    On August 6, 2014, we withdrew the proposed rule to list Graham's 
beardtongue and White River beardtongue as threatened species (79 FR 
46042). That withdrawal was based on our conclusion that the threats to 
the species as identified in the August 6, 2013, proposed listing rule 
were no longer as significant as we previously determined, such that 
the species did not meet the Act's definitions of an ``endangered 
species'' or of a ``threatened species.'' We based this conclusion on 
our analysis of new information concerning current and future threats 
to the species and conservation efforts. As a result, we also withdrew 
our associated August 6, 2013, proposed rule to designate critical 
habitat for these species.
    On March 26, 2015, a complaint was filed in the District Court for 
the District of Colorado by Rocky Mountain Wild, Center for Biological 
Diversity, Utah Native Plant Society, Southern Utah Wilderness 
Alliance, Grand Canyon Trust, Western Resource Advocates, and Western 
Watersheds Project challenging the withdrawal of the proposal to list 
Graham's beardtongue and White River beardtongue (Rocky Mountain Wild 
v. Walsh, No. 15-615 (D. Colo. filed Mar. 26, 2015)). The State of 
Utah, SITLA and PLPCO, and Uintah County, Utah, intervened in the 
litigation (Mot. to Intervene, ECF No. 10). On October 25, 2016, the 
court found that the withdrawal was contrary to the Act because (1) we 
concluded that yet-to-be-enacted regulatory and non-regulatory measures 
mandated by the 2014 CA were ``existing regulatory mechanisms''; (2) we 
failed to account for the 2014 CA's expiration when determining whether 
the beardtongues face material threats in the ``foreseeable future''; 
and (3) we took into account economic considerations when imposing a 
300-ft (91.4-m) buffer zone around each beardtongue (Order Vacating 
Admin. Action and Req. Meet-and-Confer Between the Parties, ECF No. 
59).
    However, before entering final judgment, the court ordered that the 
parties meet to discuss whether the 2014 CA could be modified in a 
manner satisfactory to plaintiffs. Those meetings occurred, but in a 
December 15, 2017, Joint Status Report to the court, the parties 
reported that they were unsuccessful at reaching agreement. Therefore, 
on December 18, 2017, the court entered final judgment, vacating our 
August 6, 2014, withdrawal, and reinstating the proposed listing and 
critical habitat rules. As a result, the August 6, 2013, proposed 
listing and

[[Page 2109]]

critical habitat rules (collectively referred to as the 2013 proposed 
rules) for Graham's beardtongue and White River beardtongue were 
reinstated, and both species once again became proposed for listing 
under the Act. The court did not establish a firm deadline for us to 
reach a new final listing determination but provided that plaintiffs 
could return to the court to seek such a deadline if the Service did 
not publish a new final determination by September 30, 2019. The 
plaintiffs have not yet done so.
    On September 12, 2019, we reopened the comment periods on the 2013 
proposed rules for 30 days, ending October 15, 2019 (84 FR 48090). We 
also announced that we would reevaluate the status of both species to 
determine whether they meet the Act's definition of an ``endangered 
species'' or of a ``threatened species,'' or whether they are not 
warranted for listing. We invited the public to comment on the 2013 
proposed rules, and we requested new information regarding Graham's 
beardtongue and White River beardtongue that had become available since 
the publication of the 2013 proposed rules to inform our evaluation. We 
also announced the availability of new survey and monitoring 
information that had become available since the publication of our 2013 
proposed rules, and we announced the availability of the final 2014 CA, 
a 2018 addendum to the 2014 CA, and modified conservation areas under 
the 2014 CA.

Supporting Documents

    We prepared two Biological Reports for Graham's beardtongue and 
White River beardtongue (Service 2021a, Service 2021b) (hereafter 
referred to as the Biological Reports), using concepts from the 
Service's species status assessment (SSA) framework (Smith et al. 2018, 
entire). The first Biological Report (Service 2021a, entire) represents 
a compilation of the best scientific and commercial data available 
concerning the current condition of the two species, including the 
impacts of past and present influences (both negative and beneficial) 
on the beardtongues, as well as a discussion of our recommendations for 
avoidance buffers and surface disturbance caps. The second Biological 
Report (Service 2021b, entire) represents a compilation of the best 
scientific and commercial data available concerning the projected 
future condition of the two species, including the impacts of 
influences (both negative and beneficial) that are anticipated to 
affect the beardtongues into the future. In accordance with our joint 
policy on peer review published in the Federal Register on July 1, 1994 
(59 FR 34270), and our August 22, 2016, memorandum updating and 
clarifying the role of peer review of listing actions under the Act, we 
sought the expert opinions of three appropriate subject matter 
specialists regarding our Biological Report of Current Condition and 
five appropriate subject matter specialists regarding our Biological 
Report of Future Condition for the two beardtongues. We received 
responses from three specialists on our Biological Report of Current 
Condition and from four specialists on our Biological Report of Future 
Condition, which informed the underlying analysis and scientific basis 
for this document. (Some peer reviewers reviewed both biological 
reports). In preparing this listing determination, we incorporated the 
results of these reviews into our final biological reports, as 
appropriate.
    We also sent the Biological Reports to partners, including the 
signatories to the 2014 CA (BLM; Utah DNR; SITLA; PLPCO; Uintah County, 
Utah; Rio Blanco County, Colorado). The Biological Reports and other 
materials relating to this listing determination can be found on the 
Mountain-Prairie Region website at https://www.fws.gov/mountain-prairie/es/GrahamsAndWhiteRiverBeardtongue.php and at https://www.regulations.gov under Docket No. FWS-R6-ES-2019-0029.

Summary of Comments and Recommendations

    As stated above under Previous Federal Actions, on August 6, 2013, 
we published proposed rules to list Graham's beardtongue and White 
River beardtongue as threatened species and to designate critical 
habitat (78 FR 47590 and 47832). These proposed rules each had a 60-day 
comment period, ending October 7, 2013. We also contacted appropriate 
Federal and State agencies, scientific experts and organizations, and 
other interested parties and invited them to comment on the proposals. 
Newspaper notices inviting general public comment and announcing our 
informational meeting and public hearing were published in the Salt 
Lake Tribune, Deseret News, and Uintah Basin Standard. On May 6, 2014, 
we announced the reopening of the public comment period on our 2013 
proposed listing and proposed designation of critical habitat rules 
until July 7, 2014 (79 FR 25806). We received requests for a public 
hearing, which was held in Vernal, Utah, on May 28, 2014.
    Subsequently, we withdrew the 2013 proposed rules and then later 
reinstated them following litigation. As a result, on September 12, 
2019, we again reopened the comment period on the 2013 proposed rules 
for 30 days (84 FR 48090). We then developed two Biological Reports 
regarding the two species' current and future conditions (Service 
2021a, 2021b), each of which underwent peer review. Responses to 
comments we received during the comment period for our September 12, 
2019, document and from peer reviews of the Biological Reports are 
provided below. For additional responses to comments for which there is 
no updated information since 2014, please see the August 6, 2014, 
withdrawal of the 2013 proposed rules (79 FR 46042). All substantive 
information provided during all peer reviews and all comment periods 
has either been incorporated directly into this final determination or 
our Biological Reports as appropriate or is addressed below. Comments 
related to our 2013 proposed critical habitat designation are not 
addressed here; given the decision to withdraw the listing proposal, no 
further assessment of the proposed critical habitat designation is 
necessary at this time.

Peer Review Comments

    We reviewed all comments on the Biological Reports that we received 
from the peer reviewers for substantive issues and new information 
regarding the beardtongues. One peer reviewer provided favorable 
support of the metrics used to evaluate the beardtongues' current and 
future condition and provided no edits to the documents. Three peer 
reviewers provided additional information, clarifications, and 
suggestions, which we have either incorporated into the Biological 
Reports or addressed below.
    (1) Comment: One reviewer stated that it does not seem logical that 
large Graham's beardtongue populations contain such a wide range of 
plant abundance (between 171 and 19,735 plants). The reviewer 
recommended that we provide different delineations of small, medium, 
and large population sizes for the beardtongues, and they suggested the 
following categories: Small population size between 0 and 100 plants; 
medium population size between 101 and 1,000 plants; and large 
population size greater than 1,000 plants.
    Our Response: The recommendation may be appropriate for species 
that do not have a population viability analysis (PVA), or a peer-
reviewed PVA. However, we delineated the population size categories 
based on a peer-reviewed PVA for the beardtongues. We calculated the 
extinction risk of each beardtongue population and considered large 
Graham's beardtongue populations to have an extinction risk of less 
than

[[Page 2110]]

five percent over a 50 year period (USFWS 2021a, pp. 59-61). Large 
Graham's beardtongue populations must have a minimum of 131 plants and 
the largest population with 19,735 plants (population 27) has a much 
lower extinction risk (less than one percent) compared to another 
population with 171 plants (between four and five percent). Our large 
population delineation identifies a lower threshold than what the 
reviewer suggested since it is based on a species-specific evaluation 
rather than generalized categories that do not take into account a 
species' life history or demography. We considered the PVA results to 
provide the best available information to delineate the beardtongues' 
population size categories, and as such did not make any changes in 
response to this comment.
    (2) Comment: One reviewer recommended that our 300-ft (91.4-m) 
avoidance buffer incorporate pollinator foraging distances for the 
primary pollinators to ensure adequate beardtongue pollination and 
reproduction.
    Our Response: We considered the effects to individual plants, 
populations, and pollinators when developing our avoidance buffer and 
surface disturbance cap recommendations. Our recommended 300-ft (91.4-
m) avoidance buffer protects individual beardtongue plants from 
occupied habitat loss and effects from fugitive dust and invasive 
weeds. Our recommended surface disturbance caps limit pollinator 
habitat loss and were designed to be used in tandem with the avoidance 
buffer to maintain population-level processes such as visitation and 
gene flow by pollinators as well as the condition of the beardtongues' 
populations. We evaluated pollinators and their needs at the 
beardtongue population level to support gene flow between plants and 
population-level reproduction rather than at an individual plant level. 
We incorporated pollinator foraging distances into our surface 
disturbance cap recommendation to restrict the amount of habitat loss 
and fragmentation within a beardtongue population's pollinator habitat. 
We delineated a population's pollinator habitat based on the foraging 
distance of the beardtongues' largest pollinators: 2,297 ft (700 m) for 
Graham's beardtongue and 1,640 ft (500 m) for White River beardtongue. 
Based on our review of the best available information and current 
habitat loss within pollinator habitat of beardtongue populations, the 
needs of pollinators and beardtongue reproduction can be supported even 
with some loss of pollinator habitat that occurs outside of the 300-ft 
(91.4-m) plant avoidance buffer (USFWS 2021a, Appendix E). Current 
levels of habitat loss within the pollinator habitat of long-term 
monitoring plots are low, ranging from zero to five percent, with no 
statistically significant negative effects to pollinator visitation or 
beardtongue reproduction (USFWS 2021a Appendix E). Published literature 
indicates that these negative effects are realized after considerable 
habitat loss has occurred for other species and habitats (USFWS 2021a 
Appendix E). Our recommendations are consistent with supporting the 
needs of pollinators and population-level gene flow within relatively 
intact habitat conditions. Together, the avoidance buffer and surface 
disturbance caps within conservation areas should conserve beardtongue 
plants and their pollinators from stressors at two different scales.
    (3) Comment: One reviewer commented that our knowledge of the 
beardtongues' current distribution is incomplete due to lack of surveys 
on Tribal lands and the State of Utah Department of Wildlife Resources 
lands in Range Unit 2. Surveys are needed in these areas.
    Our Response: We acknowledge the lack of surveys in these areas in 
our Biological Reports. Our determinations on listing the two species 
are based on the best available scientific information.
    (4) Comment: One reviewer commented that we omitted review surveys, 
impacts, and new information for the beardtongues from the Questar 
Mainline 103 pipeline replacement project. White River beardtongue 
plants had established in a roadside berm that was created by the 
initial disturbance between 2009 and 2012. Field observations indicate 
that White River beardtongue plants were able to establish or 
reestablish in roadcuts and other disturbance areas.
    Our Response: We reviewed the 2012 environmental assessment 
prepared by the Federal Energy Regulatory Commission (FERC) for this 
project, and pre-construction surveys were performed for the 
beardtongues; however, no beardtongue plants were located within the 
project right-of-way. We mention in the Biological Reports that White 
River beardtongue occupies some disturbance areas and exhibits some 
tolerance to habitat disturbance.
    (5) Comment: One reviewer commented that it may be worth noting 
that sparsely vegetated shale barren habitat on ridgelines that are 
considered potential habitat for the beardtongues are attractive off-
road vehicle (OHV) routes.
    Our Response: We mention the potential for OHV use to occur in the 
beardtongues' habitat in the Biological Reports. However, the best 
available information does not indicate that OHV use is occurring there 
or impacting plants or populations. Therefore, we did not consider OHV 
use as a stressor in our analysis.
    (6) Comment: One reviewer commented that the beardtongues' survey 
results in the Red Leaf lease area on State lands may not be included 
in the population estimates or maps provided in the draft Biological 
Report.
    Our Response: We reviewed our dataset and confirmed that the 
beardtongues' survey results for this area are included in the 
population estimates and maps provided in the Biological Report.
    (7) Comment: One reviewer recommended that we include the 2020 
beardtongues' survey results in Colorado in the Biological Reports.
    Our Response: We added the 2020 survey results to the Biological 
Reports and considered them in our evaluation of the beardtongues' 
current and future condition. These survey results increased the number 
of Graham's beardtongue plants in population 22 by 565 plants and 
reduced the number of White River beardtongue plants in population 10 
by 1,039 plants.
    (8) Comment: One reviewer questioned whether the high energy 
development scenario is plausible over the next 10 years because of the 
lack of oil shale commercial development in the Uinta Basin and the 
checkerboard pattern of landownership that would add complexity, time, 
and uncertainty to the development of these lands.
    Our Response: We intended the high energy development scenario to 
illustrate the worst-case impacts from energy development. We also 
recognize that this scenario, while plausible, may be less likely to 
occur than other scenarios, and that actual future impacts may range 
anywhere between that scenario and the current condition.

Public Comments

    (9) Comment: Several commenters stated that the Service should 
complete an updated threat assessment and provide the public with an 
opportunity to comment prior to making a final listing determination 
and critical habitat designation. Commenters believe that threats 
documented in the 2013 proposed listing rule are still present and oil 
spills from pipeline ruptures are a new threat associated with energy 
development that was not previously addressed. Commenters stated that 
White River beardtongue should be

[[Page 2111]]

listed as an endangered species, not a threatened species, due to 
imminent threats. One commenter mentioned the landscape surrounding 
beardtongue populations in Colorado has been heavily fragmented by 
existing energy development infrastructure; if completed, a proposed 
rail line in the Uinta Basin could increase energy development impacts 
to the beardtongues.
    Our Response: We completed a new threat assessment that is 
presented in our Biological Reports (Service 2021a, entire; 2021b, 
entire), and summarized in this document. We evaluated stressors to the 
beardtongues and considered new information, including current and 
projected future levels of habitat loss and fragmentation within the 
beardtongues' pollinator habitat and planned projects including the 
proposed Uinta Basin rail line. The best available information does not 
indicate that negative impacts to the beardtongues have occurred or are 
expected to occur from oil spills.
    (10) Comment: Multiple commenters mentioned the need for improved 
surface disturbance caps and buffers to protect the plants from 
negative impacts from development. The 300-ft (91.4-m) buffer from 
surface-disturbing activities as outlined in the 2014 CA is less than 
the 2,297-ft (700-m) proposed critical habitat area surrounding known 
occurrences; buffers of at least 650 ft (200 m) are needed to conserve 
pollinators until the research by Barlow and Pavlik is completed to 
determine minimum habitat areas for populations.
    Our Response: We evaluated the best available information to inform 
our recommended avoidance buffer and surface disturbance caps in our 
Biological Report of current condition (Service 2021a, pp. 81-82). For 
more information refer to our response to Comment 2, above. We did not 
rely on the Barlow and Pavlik road impact evaluation to inform our 
avoidance buffer recommendation, because we and a peer reviewer 
identified concerns regarding their assumption that roads were major 
drivers of the beardtongues' plant size and reproductive effort, and 
the lack of evidence supporting this assumption from published 
literature (Barlow and Pavlik 2020, entire; McNellis 2021a and 2021b, 
entire; Service 2021a, p. 41). We considered the Barlow and Pavlik road 
impact evaluation to be an exploratory model where the results are 
predictions to be tested and do not demonstrate causation (Service 
2021a, p. 41).
    (11) Comment: Multiple commenters were concerned that the 
conservation areas in the 2014 CA protect less acreage (44,373 ac) than 
the amount of area that was proposed for critical habitat (67,959 ac 
(27,502 ha)). The 2014 CA protects only 78 percent of the population of 
Graham's beardtongue and 59 percent of the population of White River 
beardtongue; the conservation areas do not include all White River 
beardtongue plants and habitat in the Book Cliffs, which the commenters 
believed was insufficient. They recommend expanding conservation areas 
on Federal and State lands to avoid listing both species as threatened 
under the Act. Multiple commenters stated that critical habitat should 
include all plants identified in surveys to-date. Three commenters 
stated that research on White River beardtongue identified the taxon 
has small and isolated populations with low levels of genetic diversity 
(Rodriguez-Pe[ntilde]a et al. 2018), and it is important to protect 
habitat for as many populations as possible to ensure future genetic 
viability.
    Our Response: There are many ways to achieve conservation of the 
beardtongues. The proposed critical habitat designation identified all 
populations known in 2013, with the understanding that critical habitat 
alone would not convey or guarantee conservation, because critical 
habitat protections for plants do not apply on non-Federal lands 
without a Federal action. The proposed critical habitat designations 
for the two beardtongue species overlapped and totaled 75,846 ac 
(30,694 ha). Proposed critical habitat on Federal lands alone would 
apply to only 38 percent of the population of Graham's beardtongue 
(21,301 plants) on 41,668 ac (16,862 ha), and 27 percent of the 
population for White River beardtongue (7,942 plants) on 5,758 ac 
(2,330 ha) (Service 2021a, Appendix B, p. 86). The 2014 CA conserves a 
smaller amount of habitat in designated conservation areas (42,993 ac 
(17,399 ha)) than we proposed as critical habitat but provides 
protections to a similar percentage of the Graham's beardtongue 
population and a much larger percentage of the White River beardtongue 
population than afforded by proposed critical habitat on Federal lands. 
The 2014 CA protects 41 percent of Graham's beardtongue plants (23,333 
plants) and 66 percent (19,710 plants) of White River beardtongue 
plants on Federal and non-Federal lands (Service 2021b, pp. 44-45). The 
2014 CA conservation areas support 1,094 White River beardtongue plants 
in the Book Cliffs population to maintain a large population size with 
a low risk of extinction (less than 5 percent risk of extinction over a 
50-year period). In addition, the conservation areas are strategically 
placed to provide habitat connectivity, thereby conserving the 
resiliency, redundancy, and representation (e.g., genetic diversity) of 
the beardtongues across their ranges (Service 2021a, pp. 42-45; 
Penstemon Conservation Team 2014, entire; Penstemon Conservation Team 
2018b, 2018c, entire).
    (12) Comment: Multiple commenters expressed concern that the 
private parties will end their participation in the 2014 CA in 2029.
    Our Response: The duration of the 2014 CA is 20 years (until 2034) 
for Federal, State, and county parties, and 15 years (until 2029) for 
private parties. During this time, we hope that information regarding 
the likelihood of energy development beyond 2030 becomes available. We 
committed to assess the status of the beardtongues by December 31, 
2028, prior to the private parties leaving the agreement. If, during or 
after this timeframe, either species meets the Act's definition of an 
``endangered species'' or a ``threatened species,'' we can act to 
protect the species through the listing process. If the beardtongues 
are listed under the Act, the 2014 CA expires to avoid a situation 
where the parties are bound to both the commitments in the agreement 
and the requirements of the Act. This conservation framework provides a 
consistent regulatory framework for landowners or managers who may be 
affected, while still protecting the beardtongues under either 
scenario.
    (13) Comment: Commenters expressed concern that the voluntary 
nature of the 2014 CA by private parties is inadequate and will lead to 
inconsistent management of the beardtongues. The Federal agencies do 
not have regulatory mechanisms in place to enforce the conservation 
measures in the 2014 CA on Federal land, and there are no regulatory 
mechanisms in place that provide the necessary landscape-level 
protections to the beardtongues from the threats identified in the 2013 
proposed rules. The results of livestock monitoring and assessments 
were not made available to the public; commenters questioned whether 
monitoring was conducted according to the schedule identified in the 
livestock grazing plan.
    Our Response: The 2014 CA was developed by county, State, and 
Federal entities that have the authority to regulate and permit 
activities on lands within their jurisdiction that overlap with the 
beardtongues' habitat. These parties are implementing the voluntary 
agreement and providing protections to the beardtongues that we 
considered in

[[Page 2112]]

this listing determination. We summarize the regulatory mechanisms 
implemented by each party, the accomplishments of the 2014 CA, 
livestock monitoring, and corrective actions in our 2021 Biological 
Reports (Service 2021a, pp. 42-45, 54-56; 2021b, pp. 43-48).
    (14) Comment: Multiple commenters stated the beardtongues continue 
to be at risk of extinction due to small population size and isolation. 
The 2018 population size is misleading and unknown because: (a) Surveys 
were performed inconsistently and haphazardly across the beardtongues' 
ranges and were not derived from annual censuses or a scientifically 
robust sampling design; (b) plants counted in one year may have been 
counted in subsequent years; and (c) the Service's assumptions that no 
previously documented plants have died of natural or human causes or 
that all previously documented plants have been replaced by new plants 
are incorrect, and there is no data to support them. One commenter 
noted that some beardtongue species tend to form an extended 
underground root system and that the beardtongues' total population 
sizes could be much smaller than our population estimates.
    Our Response: We stated in our 2021 Biological Reports and past 
rulemakings that the total known number of beardtongues has increased 
over time based on new survey information rather than increasing 
population trends. Our 2018 population estimates were based on long-
term demographic monitoring information that indicate adult beardtongue 
plants are long-lived (30 years or more) and maintain high survival 
rates, and populations are generally stable (Pavlik et al. 2015, 
entire). Therefore, it is reasonable to assume that plants continue to 
persist on the landscape unless there is human modification of the 
habitat, or there are high-intensity sheep grazing incidents. We and 
our partners reviewed all survey information and removed duplicate 
records to minimize the double-counting of individual plants. There is 
no indication that the beardtongues form extended underground root 
systems based on past excavations and translocations of individual 
plants.
    (15) Comment: Multiple commenters requested an extension of the 
public comment period and the release of survey results and livestock 
monitoring data that became available after the publication of the 2013 
proposed rules.
    Our Response: We have held three comment periods on the proposed 
rules. We held our first comment period for 60 days, from August 6 to 
October 7, 2013 (see 78 FR 47590 and 47832); our second comment period 
for 60 days, from May 6 to July 7, 2014 (see 79 FR 25806), during which 
we also held a public information meeting and public hearing on May 28, 
2014; and our third comment period for 30 days, from September 12 to 
October 15, 2019 (see 84 FR 48090). Therefore, we have provided 
sufficient opportunities for the public to comment on the proposals. 
During each of the three comment periods, we made available any survey 
and livestock monitoring data that we had at that time. Specifically, 
during our third public comment period in 2019, we announced the 
availability of the latest survey results and other information that 
had become available since 2013.
    (16) Comment: One commenter stated that incompatible livestock 
grazing is occurring on Federal lands, all beardtongue sites within 
Federal conservation areas should meet BLM Rangeland Health Standards, 
and monitoring should continue to assess habitat conditions and inform 
management decisions.
    Our Response: Livestock grazing appears to be compatible with 
conservation of the beardtongues except for intensive sheep grazing 
events that occur in localized areas (USFWS 2021a, pp. 54-56). The BLM 
is addressing livestock impacts to the beardtongues on Federal lands as 
per the 2014 CA. The 2014 CA states that BLM will monitor beardtongues' 
impacts from grazing and will adjust grazing regimes accordingly to 
reduce associated impacts. For example, BLM implemented corrective 
actions that were successful in removing grazing impacts to Graham's 
beardtongue in the Raven Ridge Area of Critical Environmental Concern 
(ACEC) in Colorado, and BLM continues to monitor livestock impacts to 
the beardtongues and evaluate rangeland health (Service 2021a, p. 55). 
BLM is required to manage rangelands as per the requirements of 43 CFR 
part 4100, subpart 4180 (``Fundamentals of Rangeland Health and 
Standards and Guidelines for Grazing Administration'' (Rangeland 
Health)) and implement the agency's policy guidelines identified in the 
Standards for Rangeland Health.
    (17) Comment: A commenter stated that surface disturbance of all 
kinds affects the beardtongues' pollinators; cattle trampling results 
in greater impacts to the ground surface than other herbivores.
    Our Response: The best available information indicates that the 
beardtongues maintain a diverse pollinator assemblage and adequate 
reproduction under permitted grazing regimes. Monitored populations of 
the beardtongues that overlap active grazing allotments reproduce by 
seed on an annual basis and demonstrate reproductive rates that are not 
pollinator-limited (Barlow and Pavlik 2020, p. 5).
    (18) Comment: A commenter stated that monitoring reports indicate 
that herbivory from many sources may impact the beardtongues' ability 
to successfully replenish the seedbank. Herbivory resulted in high 
levels of stress to Graham's beardtongue in 2014, and low seedling 
survivorship.
    Our Response: Herbivory to the beardtongues appears to be a natural 
stressor to beardtongue individuals and is primarily attributed to 
native grazers (e.g., rodents, rabbits), rather than livestock (Service 
2021a, p. 54). Monitored populations of both species continue to remain 
stable despite the regular frequency, and occasional high levels, of 
herbivory.
    (19) Comment: The State of Utah provided information that the 
number of new oil and gas wells dropped by 67 percent between 2014 and 
2015, due to the drop in crude oil and natural gas prices; should 
prices rebound, the increasing use of horizontal well drilling could 
reduce the amount of future surface disturbance. Should the market 
demand for oil shale increase to an economically favorable price, 
development of this resource may be focused on the richer Piceance 
Basin in Colorado rather than on the Uinta Basin in Utah. Because of 
the low likelihood of development from oil and gas in the foreseeable 
future, the Service should not list the beardtongues. Another commenter 
stated that a determination to list a species as a threatened species 
under the Act requires a determination as to the likelihood rather than 
the mere prospect that a species will or will not become endangered in 
the foreseeable future. The likely threshold of Graham's and White 
River beardtongues to become an endangered species in the foreseeable 
future was suspect in the August 6, 2013, proposed listing rule (78 FR 
47590); was mitigated by the 2014 CA; and is better stated as unlikely 
with the discoveries of new populations, the species' range expansion, 
and the success in research resulting from the 2014 CA.
    Our Response: We note that the Act defines 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 term ``foreseeable future'' extends only so far into the 
future as the Service can reasonably

[[Page 2113]]

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. See the 
Regulatory Framework section below for further information on how we 
make determinations on whether to list a species under the Act.
    We evaluated the likelihood and location of future energy 
development (oil shale, tar sands, traditional oil and gas development) 
within the beardtongues' ranges in our Biological Reports based on the 
best available information, expert opinion, and peer review (Service 
20201a, pp. 45-54; Service 20201b, pp. 15-38, Appendix). Our analysis 
of projected future energy development evaluates worst-case impacts 
under the moderate and high energy development scenarios until 2030, 
which is the date through which reliable predictions can be made based 
on current information.
    (20) Comment: Commenters including the State of Utah stated that 
the rangewide population estimates for the beardtongues have greatly 
increased since 2013. The known population of Graham's beardtongue 
increased by 177 percent, and the known population of White River 
beardtongue increased by 284 percent.
    Our Response: As stated by the commenters, the rangewide population 
estimates for the beardtongues have greatly increased since 2013, based 
on new survey information and a genetic evaluation of White River 
beardtongue. Although we want to emphasize that the increase in 
population size does not mean the total population is increasing. 
Rather, additional survey results provide a more complete picture of 
how many beardtongue plants exist across their ranges (USFWS 2021a, pp. 
21, 28). Monitoring indicates the beardtongue populations are stable in 
size.
    (21) Comment: The State of Utah and other commenters expressed 
support for the 2014 CA as an appropriate regulatory mechanism to 
promote research, surveys, and stakeholder engagement. Uintah County, 
Utah, enacted a zoning ordinance for a 15-year period until 2029, to 
apply surface disturbance caps and implement a 300-ft (91.4-m) 
avoidance buffer for 2014 CA conservation areas on private lands. The 
signatories to the 2014 CA have provided considerable staff time and 
funding to implement the agreement; successfully implemented surveys, 
research, monitoring, and planning commitments; expanded conservation 
areas; committed to providing a summary report of accomplishments every 
5 years; and extended the 2014 CA protections on State and Federal 
lands for a total of 20 years until July 25, 2034. Uintah County 
expressed their commitment to the conservation of the beardtongues and 
stated the goal of the 2014 CA is to ensure the beardtongues thrive 
long after the expiration of the agreement.
    Our Response: The signatories are implementing the 2014 CA, and 
their many contributions were summarized by State members of the 
agreement (Sheppard and Wheeler 2020, entire). New commitments made by 
signatories were summarized in the 2014 CA's 2018 addendum, which 
includes the Service's commitment to assess the beardtongues' status by 
December 31, 2028. We have considered the 2014 CA and its 2018 addendum 
in this listing determination.

Background

    A comprehensive review of the taxonomy and morphology, habitat, 
life history and resource needs, population distribution and status, 
and pollinator information for both Graham's beardtongue and White 
River beardtongue is presented in our Biological Report of current 
condition (Service 2021a, pp. 13-41) and is briefly summarized here.
    Graham's and White River beardtongues are endemic plants found in 
northeastern Utah and northwestern Colorado. Graham's beardtongue 
occurs in 27 populations, with a total population of 56,385 
individuals, across the Uinta Basin in Duchesne and Uintah Counties in 
Utah and Rio Blanco County in Colorado (Service 2021a, pp. 21-27). 
White River beardtongue occurs in 17 populations, with a total 
population of 29,902 individuals across the Uinta Basin and at an 
isolated location in the Book Cliffs in Grand and Uintah Counties in 
Utah and Rio Blanco County in Colorado (Service 2021a, pp. 28-33). For 
the purposes of our analysis, we grouped the populations for each 
species into five range units (i.e., metapopulation areas). The two 
species overlap with each other in four of their range units in the 
central and eastern portion of their ranges in Utah and Colorado. The 
occupied habitat area for Graham's and White River beardtongues is 
9,585 ac and 3,462 ac of habitat, respectively. Their pollinator 
habitat area includes beardtongue occupied habitat and a larger 
pollinator foraging area, which collectively comprise 91,232 ac and 
29,476 ac for Graham's beardtongue and White River beardtongue, 
respectively.
    Graham's and White River beardtongues have highly specific soil 
requirements and occupy exposed oil shale strata of the Green River 
geologic formation. The beardtongues are long-lived perennial plant 
species that flower in the spring and summer months, and both species 
require pollinators for maximum plant reproduction. Plant survival and 
successful recruitment require suitable soils with microsites for 
establishment and growth. The sparse canopy coverage of associated 
vegetation likely results in low competition from other plants, and the 
beardtongues appear to be poor competitors with weeds. Reproductive 
success and maintenance of genetic diversity of these two beardtongues 
require habitat that supports generalist and specialist pollinators, 
primarily bees and a specialist wasp. For more detailed information 
about the biology of both beardtongue species, see our Biological 
Report of current condition (Service 2021a, pp. 13-41).

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 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.
    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

[[Page 2114]]

known to or are reasonably likely to negatively affect individuals of a 
species. The term ``threat'' includes actions or conditions that have a 
direct impact on individuals (direct impacts), as well as those that 
affect individuals through alteration of their habitat or required 
resources (stressors). The term ``threat'' may encompass--either 
together or separately--the source of the action or condition or the 
action or condition itself.
    However, the mere identification of any threat(s) does not 
necessarily mean that the species meets the statutory definition of an 
``endangered species'' or a ``threatened species.'' In determining 
whether a species meets either definition, we must evaluate all 
identified threats by considering the expected response by the species, 
and the effects of the threats--in light of those actions and 
conditions that will ameliorate the threats--on an individual, 
population, and species level. We evaluate each threat and its expected 
effects on the species, then analyze the cumulative effect of all of 
the threats on the species as a whole. We also consider the cumulative 
effect of the threats in light of those actions and conditions that 
will have positive effects on the species, such as any existing 
regulatory mechanisms or conservation efforts. The Secretary determines 
whether the species meets the definition of an ``endangered species'' 
or a ``threatened species'' only after conducting this cumulative 
analysis and describing the expected effect on the species now and in 
the foreseeable future.
    The Act does not define the term ``foreseeable future,'' which 
appears in the statutory definition of ``threatened species.'' Our 
implementing regulations at 50 CFR 424.11(d) set forth a framework for 
evaluating the foreseeable future on a case-by-case basis. The term 
``foreseeable future'' extends only so far into the future as the 
Service can reasonably determine that both the future threats and the 
species' responses to those threats are likely. In other words, the 
foreseeable future is the period of time in which we can make reliable 
predictions. ``Reliable'' does not mean ``certain''; it means 
sufficient to provide a reasonable degree of confidence in the 
prediction. Thus, a prediction is reliable if it is reasonable to 
depend on it when making decisions.
    It is not always possible or necessary to define foreseeable future 
as a particular number of years. Analysis of the foreseeable future 
uses the best scientific and commercial data available and should 
consider the timeframes applicable to the relevant threats and to the 
species' likely responses to those threats in view of its life-history 
characteristics. Data that are typically relevant to assessing the 
species' biological response include species-specific factors such as 
lifespan, reproductive rates or productivity, certain behaviors, and 
other demographic factors.

Analytical Framework

    The Biological Reports document the results of our comprehensive 
biological review of the best scientific and commercial data regarding 
the status of the two species, including an assessment of the potential 
threats to the species. The Biological Reports do not represent a 
decision by the Service on whether these species should be listed as 
endangered or threatened species under the Act. However, they do 
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 discussions 
provide summaries of the key results and conclusions from the 
Biological Reports; the full Biological Reports can be found on the 
Mountain-Prairie Region website at https://www.fws.gov/mountain-prairie/es/GrahamsAndWhiteRiverBeardtongue.php and at https://www.regulations.gov under Docket No. FWS-R6-ES-2019-0029.
    To assess Graham's beardtongue and White River beardtongue 
viability, we used the three conservation biology principles of 
resiliency, redundancy, and representation (Shaffer and Stein 2000, pp. 
306-310; Smith et al. 2018, p. 304) (hereafter referred to as the 3Rs). 
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.
    Our Biological Reports used many of the concepts of the Service's 
SSA framework (Smith et al. 2018, entire) and followed sequential 
stages to characterize the viability of the Graham's and White River 
beardtongues. In our Biological Report of current condition (Service 
2021a), we first evaluated the individual species' life-history needs. 
The next stage involved an assessment of the historical and current 
condition of the species' demographics and habitat characteristics, 
including an explanation of how each species arrived at its current 
condition. In our Biological Report of future condition (Service 
2021b), the final stage involved making predictions about the species' 
responses to positive and negative environmental and anthropogenic 
influences. Throughout all of these stages, we used the best available 
information to characterize viability as the ability of a species to 
sustain populations in the wild over time. We use this information to 
inform our regulatory decisions.

Summary of Biological Status and Threats

    In preparing the Biological Reports for Graham's and White River 
beardtongues, we reviewed available reports and peer-reviewed 
literature, we incorporated survey information, and we sought 
information from experts regarding the species' primary stressors to 
further refine our analysis. We identified uncertainties and data gaps 
in our assessment of the current and future status of both species. In 
this discussion, we briefly summarize the biological condition of both 
species and their resources, the influence of those conditions on the 
species' overall viability, and the risks to that viability. For a full 
description of our analysis of each species' biological status, current 
condition, and projected future condition, see our Biological Reports 
(Service 2021a, 2021b).

Life-History Needs

    At the individual level, both Graham's beardtongue and White River 
beardtongue need suitable soils (shallow soils with virtually no soil 
horizon development with a surface usually mixed with fragmented 
shale), suitable precipitation (6 to 12 inches annually), and suitable 
temperatures (including a minimum of 45 consecutive days less than 40 
degrees Fahrenheit ([deg]F) in the winter months) to support plant 
growth (Service 2021a, pp. 17, 20). To support plant reproduction, the 
plants need visitation and pollination by bee and wasp pollinators, and 
floral resources for pollinators provided by the associated plant 
community, including

[[Page 2115]]

the presence of other beardtongue species (Service 2021a, pp. 17, 20). 
Suitable microsites that provide cover or shelter for seed germination, 
establishment, and growth are also needed to support both species 
(Service 2021a, pp. 17, 20).
    For Graham's and White River beardtongues to maintain viability, 
their populations or some portion of their populations must be 
sufficiently resilient (i.e., able to sustain populations in the face 
of environmental variation). At the population level, important habitat 
needs for the beardtongues include: (1) Suitable soil substrate to 
maximize recruitment and survival within the population (soil and 
microsite quality); (2) sufficient floral resources to ensure 
pollinator visitation and maximize adult reproductive output; (3) 
suitable climate conditions (temperature, moisture) within species' 
physiological tolerances to maximize population growth and size; and 
(4) sufficient seed dispersal and contribution to the seed bank to 
support population stability or growth. If these habitat factors occur 
over an area of sufficient size to support a sufficient population size 
and the demographic needs of the species, we anticipate plant 
populations will retain sufficient resiliency to withstand natural 
stochastic events (Service 2021a, pp. 33-34).
    Based on their population demographics, we expect that survival of 
established plants (i.e., vegetative and adult (reproductive) plants) 
and high reproductive output are the most important factors 
contributing to the growth rate and size of populations (Service 2021a, 
pp. 34-35). Lastly, resiliency of populations is also influenced by the 
degree of connectivity among populations (Service 2021a, p. 35).
    At the species level, Graham's and White River beardtongues each 
need multiple, sufficiently resilient, connected populations that 
represent the range of ecological and genetic diversity across their 
ranges (Service 2021a, p. 35). Populations that are connected allow for 
immigration and emigration across the landscape and ensure gene flow 
and recolonization following extirpation of individual sites or 
populations (Auffret et al. 2017, pp. 1-3). In order to adapt to 
changing physical and biological conditions, each species needs to 
maintain its genetic and ecological diversity (representation) and an 
adequate number and distribution of sufficiently resilient populations 
across its range (redundancy).
    Because the beardtongues rely on pollinators to maximize seed 
production and genetic diversity of plant populations, we also note 
that the persistence of the pollinator assemblage for Graham's and 
White River beardtongues depends on maintaining nesting sites and 
floral resources to support pollinator needs (Service 2021a, pp. 35-
36). Broadly, the needs of Graham's and White River beardtongue 
pollinators include intact habitat conditions and an abundance of 
floral resources throughout the growing season. For an in-depth 
discussion of the beardtongues' pollinator assemblage, pollinator life 
history, and the needs of pollinators, see our Biological Report on 
current condition (Service 2021a, pp. 35-41).

Summary of Factors Influencing Viability

    As mentioned above in Regulatory Framework, a species may be 
determined to be an endangered or threatened species due to one or more 
of the five factors described in section 4(a)(1) of the Act: (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. Potential stressors 
we evaluated for Graham's and White River beardtongue in our Biological 
Reports included: Three types of energy exploration and development: 
Oil shale, tar sands, and traditional oil and gas drilling (Factor A); 
road construction (Factor A); herbivory (Factor C); invasive weeds 
(Factor A); small population size (Factor E); and climate change 
(Factors A and E). We also evaluated how existing regulatory mechanisms 
(Factor D) or other conservation measures (primarily the 2014 CA and 
2018 addendum) may lessen the impacts of these stressors. The best 
available information does not indicate that overutilization (Factor B) 
is a threat to either beardtongue species. A brief summary of the 
potential factors affecting Graham's and White River beardtongues is 
presented below; for a full description of our evaluation of the 
effects of these stressors and conservation efforts, refer to the 
Biological Reports (Service 2021a, pp. 41-63; Service 2021b, pp. 15-
48).
Conservation Agreement
    Following publication of our August 6, 2013, proposed rules (78 FR 
47590 and 47832), we entered into a 2014 CA with the following parties: 
BLM; Utah DNR; SITLA; Uintah County, Utah; the Utah PLPCO; and Rio 
Blanco County, Colorado (Penstemon Conservation Team 2014, entire). The 
2014 CA was designed to specifically address the threats identified in 
our August 6, 2013, proposed rule to list the two species (78 FR 
47590), and expand the protections afforded to the beardtongues on 
Federal lands. The 2014 CA also provides the species protections on 
certain non-Federal lands.
    The parties committed to a number of conservation actions, 
including the establishment of 44,373 ac (17,957 ha) of occupied and 
suitable habitat as protected conservation areas on Federal and non-
Federal lands. Within the designated conservation areas, surface 
disturbance caps are applied to limit the loss and fragmentation of 
habitat from development, in conjunction with a 300-ft (91.4-m) 
avoidance buffer between disturbance and beardtongue plants. Uintah 
County enacted an ordinance to enforce the surface disturbance caps and 
avoidance buffer within conservation areas on private lands (Penstemon 
Conservation Team 2014, pp. 28, 35). Additionally, BLM implements a 
minimum 300-ft (91.4-m) avoidance buffer wherever beardtongue plants 
occur on Federal lands, as identified in BLM's resource management 
plans. The parties also developed monitoring plans that include 
adaptive management to address the cumulative impacts from livestock 
grazing, invasive weeds, small population size, and climate change by 
continuing species monitoring, monitoring climate, reducing impacts 
from grazing when and where detected, and controlling invasive weeds.
    Today, the 2014 CA remains in place, and in 2018, the parties added 
2,339 ac (947 ha) as new conservation areas for White River beardtongue 
habitat on Federal and State (SITLA) lands and removed 115 ac (47 ha) 
of low priority conservation areas (Penstemon Conservation Team 2018b 
and 2018c, entire). The parties also signed an addendum (Penstemon 
Conservation Team 2018d, entire) to extend the term of the 2014 CA by 
an additional 5 years, until 2034, for the Federal, State (SITLA, DNR), 
and county parties. The private lands in Utah will be released from the 
2014 CA when the original term ends in 2029. For the purposes of our 
analysis, we considered only the 2014 CA protections that are afforded 
to the beardtongues until 2034. Additional conservation areas under the 
2014 CA were designated as ``interim'' and only provide shorter-term 
protections. However, we did not consider plants in

[[Page 2116]]

these interim areas as protected for the purposes of our analysis. We 
are uncertain of the likelihood of 2014 CA protections continuing 
beyond 2034 when the CA expires; however, it may be possible to renew 
the CA with willing partners. As part of the CA, the Service committed 
to assess the status of the beardtongues in 2028, prior to the 
expiration of protections on private lands. For additional discussion 
and details on the 2014 CA and its accomplishments, see our Biological 
Reports (Service 2021a, pp. 42-45; Service 2021b, pp. 43-48).
Other Regulatory Mechanisms
    While the 2014 CA is a voluntary agreement, the State of Utah 
(SITLA and PLPCO), Uintah County (Utah), and Rio Blanco County 
(Colorado) used their regulatory authority to implement specific 
protections as outlined in the 2014 CA (Penstemon Conservation Team 
2014, and 2018 a, b, c, entire; Service 2021, pp. 39-43). Utah State 
law protects the beardtongues on State (SITLA) designated conservation 
areas and enforces the restrictions identified in the 2014 CA (see 
title 53C of the Utah Code, at chapter 2, part 2, section 202 (53C-2-
202), and the Utah Administrative Code, School and Institutional Trust 
Lands, at title 850, rule 150 (R850-150)). Uintah County enacted a 
zoning ordinance to enforce the surface disturbance caps and an 
avoidance buffer within conservation areas on private lands until 2029 
(Penstemon Conservation Team 2014, pp. 28, 35; Uintah County 2018, 
entire; Penstemon Conservation Team 2019, Appendix A). No other 
regulatory mechanisms provide protections to the beardtongues on 
private or State lands in Utah and Colorado.
    Other regulatory mechanisms provide protections to Graham's 
beardtongue and White River beardtongue on Federal (BLM) lands. 
Graham's and White River beardtongues are BLM sensitive plant species 
in Utah and Colorado, and are afforded protections at least comparable 
to (if not greater than) species that are candidates for Federal 
listing (BLM 2008a, p. 43). In Utah, the BLM Vernal Field Office's 
resource management plan (RMP), as amended, is the regulatory framework 
for BLM land management where the beardtongues occur (BLM 2008b, 
entire). In Colorado, the BLM White River Field Office's RMP, as 
amended, is the regulatory framework for BLM land management where the 
beardtongues occur (BLM 1997, entire; BLM 2015, entire). The 
protections in these RMPs include a 300-ft (91.4-m) avoidance buffer, 
surface disturbance restrictions on steep slopes, areas that are 
unavailable for leasing and that have no surface occupancy (NSO) 
stipulations, and ACECs. For additional detail on all of these 
regulatory mechanisms, see our Biological Report of future condition 
(Service 2021b, pp. 46-48).
Oil Shale
    Oil shale exploration (e.g., research, exploration, and 
development) activities occur on State and private lands within the 
range of the beardtongues. Oil shale exploration and development 
activities have the potential to destroy beardtongue habitat, plants, 
and populations. Currently, no exploration activities take place on BLM 
lands and no plans for commercial-scale development of oil shale exist 
within the range of both species in Utah and Colorado (BLM 2013, 
entire; Service 2019d, entire; Service 2021a and b, entire). To date, 
two oil shale exploration projects have resulted in the loss of 276 ac 
(112 ha) of Graham's beardtongue pollinator habitat and 246 Graham's 
beardtongue individuals in Population 13 on State lands (Red Leaf 
Resources 2013, entire; Red Leaf Resources 2014, entire; The Oil Mining 
Company 2014, entire; Service 2021a, pp. 45-48).
    There are 10,334 ac (4,182 ha) and 1,997 ac (808 ha) of Graham's 
and White River beardtongue pollinator habitat, respectively, under 
lease or that have a Utah Division of Oil, Gas and Mining mine permit 
(includes exploration, small and large mine permits) for oil shale 
(Service 2021a, pp. 45-48). These areas contain 35 percent (19,476 
plants) and 13 percent (4,314 plants) of Graham's and White River 
beardtongue total populations, respectively. Within oil shale lease and 
permit areas, conservation areas under the 2014 CA afford protections 
to 561 Graham's beardtongue plants and 1,678 White River plants with 
caps on new development and use of an avoidance buffer. The majority of 
beardtongue habitat within oil shale lease areas has not been impacted 
by oil shale exploration activities. Aside from the loss of Graham's 
beardtongue habitat reported above, the disturbance within lease and 
permit areas is the result of existing roads. We do not anticipate oil 
shale exploration and development activities to occur within designated 
conservation areas because of the caps on surface disturbance in the 
2014 CA.
    Based on past and current exploration and commercial development 
activities, expert opinion, and the best available information, we 
consider exploration of oil shale from 2020-2030 to be likely on State 
and private lands with high economic potential within the beardtongues' 
ranges (Service 2021b, pp. 15-17). However, we consider commercial 
development of oil shale to be about as likely as not on State and 
private lands, and unlikely on Federal lands within the beardtongues' 
ranges (Service 2021b, pp. 15-17).
Tar Sands
    Tar sands exploration and development activities are occurring on 
private, State, and BLM lands outside of Graham's and White River 
beardtongues habitat in the Uinta Basin (Service 2021a, pp. 48-49). Tar 
sands exploration and development activities have the potential to 
destroy beardtongue habitat, plants, and populations. To date, tar sand 
exploration and development activities have not resulted in the loss of 
beardtongue habitat or plants. One tar sands lease area overlaps the 
Book Cliffs population of White River beardtongue; however, no White 
River beardtongue plants or habitat within this lease area have been 
impacted by tar sand exploration activities. The 2014 CA affords 
protections to 306 plants and 97 ac (39 ha) within the State lands 
portion of the lease area and we do not anticipate tar sand exploration 
and development activities to occur within designated conservation 
areas because of the caps on surface disturbance. There are no tar sand 
leases within Graham's beardtongue habitat.
    Based on past and current exploration and commercial development 
activities, expert opinion, and the best available information, we 
consider exploration of tar sands from 2020-2030 to be likely on State 
and private lands including the PR Springs South area (Service 2021b, 
pp. 24-26). However, we consider commercial development of tar sands to 
be about as likely as not on State and private lands including the PR 
Springs South area, and unlikely on Federal lands (Service 2021b, pp. 
24-28) within the species ranges.
Traditional Oil and Gas
    Traditional oil and gas exploration and development activities are 
occurring on private, State, and BLM lands within Graham's and White 
River beardtongues habitat (Service 2021a, pp. 49-53). Traditional oil 
and gas exploration and development activities have the potential to 
destroy beardtongue habitat, plants, and populations. The best 
available information indicates that no loss of beardtongue plants from 
these activities has occurred. However, traditional oil and gas 
exploration and development activities have resulted in the loss of

[[Page 2117]]

less than one percent of the total pollinator habitat area for both 
species (Federal Energy Regulatory Commission 2012, pp. 24, 25; 
Lewinsohn 2019, entire; Moore 2019, entire). Approximately 56 percent 
of Graham's beardtongue pollinator habitat and 39 percent of White 
River beardtongue pollinator habitat on State and BLM lands are leased 
for traditional oil and gas development. Within traditional oil and gas 
lease areas, conservation areas under the 2014 CA afford protections to 
34 percent and 42 percent of the Graham's beardtongue habitat and 
plants under lease, and 36 percent and 32 percent of the White River 
beardtongue habitat and plants under lease. Overall, traditional oil 
and gas exploration and development have resulted in a low amount of 
habitat loss for the two beardtongues to date. The majority of 
beardtongue pollinator habitat within lease areas is relatively intact 
and undisturbed.
    Based on past and current exploration and commercial development 
activities, expert opinion, and the best available information, we 
consider exploration of traditional oil from 2020-2030 to be likely on 
Federal, State, and private lands within Uintah County in a Mancos 
shale deposit (the Mancos B play), and do not expect exploration of 
natural gas to occur, as it is already complete (Service 2021b, pp. 32-
33). However, we consider commercial development of natural gas to be 
likely on Federal, State, and private lands, and commercial development 
of oil to be unlikely within the species' ranges (Service 2021b, pp. 
32-34).
Road Construction and Maintenance
    Many unpaved county roads cross through Graham's and White River 
beardtongue habitat, and most of these roads have existed for decades 
(Service 2021a, pp. 53-54). Road construction and maintenance 
activities have the potential to destroy beardtongue habitat, plants, 
and populations. Plants and populations located near development 
activities are prone to the effects of dust, weed encroachment, habitat 
fragmentation, and pollinator disturbance. To date, existing roads and 
road construction have been the cause of the majority of the loss of 
beardtongue pollinator habitat. Approximately 1 percent and 1.5 percent 
of the total pollinator habitat for Graham's and White River 
beardtongue, respectively, have been lost to road construction. Road 
construction and paving projects occur infrequently, and we are not 
aware of other road construction or maintenance projects that are 
proposed to occur in areas where they would impact Graham's beardtongue 
or White River beardtongue (Baldwin 2019, entire; Federal Highway 
Administration (FHWA) 2020, entire; UDOT 2020, entire).
Herbivory
    Invertebrates, wildlife, and livestock graze individuals of 
Graham's and White River beardtongues (Sibul and Yates 2006, p. 9; 
Dodge and Yates 2010, p. 9; 2011, pp. 9, 12; UNHP 2012, entire; 78 FR 
47590, August 6, 2013; 79 FR 46042, August 6, 2014; Penstemon 
Conservation Team 2015b, entire). Herbivory is primarily due to native 
grazers rather than livestock (Penstemon Conservation Team 2019a, p. 
8). Presumably, beardtongues are adapted to herbivory by native 
grazers, which may explain why monitored populations continue to remain 
stable despite occasional high levels of herbivory by native grazers. 
Most of the Graham's and White River beardtongue populations (99 
percent) occur within BLM livestock grazing allotments, except for 
where the two species occur on private lands (Service 2021a, p. 55). As 
part of the 2014 CA, the conservation team developed a livestock 
grazing management plan (Penstemon Conservation Team 2015b, entire), 
and BLM is monitoring and implementing corrective actions (Service 
2021a, pp. 55-56). For example, following a heavy sheep grazing 
incident at Raven Ridge in Colorado, BLM conducted a site visit with 
the permittee, reviewed maps of avoidance areas for sheep trailing and 
bedding, and repaired a fence at the Raven Ridge ACEC boundary. These 
actions appear to be effective, and sheep grazing has not been detected 
within the ACEC since 2014 (Service 2021a, p. 56).
    Overall, herbivory and livestock grazing are not primary drivers of 
the beardtongues' current and future condition. The best available 
information does not indicate that future herbivory impacts would 
result in any negative population-level impact to the beardtongues. 
There is the potential for herbivory impacts to increase in populations 
on non-Federal lands that may be impacted by energy development, 
because herbivory from native grazers and livestock may increase where 
available forage is reduced as a result of energy development (Service 
2021b, pp. 38-39). We expect future herbivory impacts would be 
addressed by land management actions and would not increase in 
beardtongues' populations on Federal lands, where the BLM has committed 
to take corrective actions. However, there is no commitment to take 
corrective actions within beardtongue populations affected by 
development on non-Federal lands if future herbivory impacts increase 
(Service 2021b, pp. 38-39).
Invasive Weeds and Wildfire
    Invasive weeds are present but not extensive across most of the 
beardtongues' pollinator habitat, and the primary weed is cheatgrass. 
Invasive weeds have the potential to negatively impact seedling 
recruitment, plant abundance, and population trends of the beardtongues 
and other native plants through competitive exclusion, niche 
displacement, and changes in insect predation. Beardtongue populations 
with high cheatgrass cover (i.e., introduced annual grasslands greater 
than 20 percent of habitat area) may be at risk of an altered wildfire 
regime (Link et al. 2006, p. 116). Based on our review of the existing 
vegetation types, most beardtongue populations contain low amounts of 
cheatgrass (less than 5 percent of habitat area), which is consistent 
with monitoring reports for both species (Service 2021a, pp. 13-20, 57-
59; SWCA Environmental Consultants 2014, p. 16). We expect weed levels 
to remain low in intact beardtongue occupied habitat and increase in 
disturbed occupied habitat (Service 2021a, pp. 57-59; Service 2021a, 
pp. 8-11, Appendix B). The effects of invasive weeds may increase in 
populations that overlap with energy development (Service 2021b, p. 
39). As part of the 2014 CA, the conservation team developed a weed 
management plan. To date, BLM and Uintah County have surveyed for weeds 
along roads in conservation areas, but no new occurrences of noxious 
weed species have been detected (Penstemon Conservation Team 2017, p. 
1; Penstemon Conservation Team 2018a, p. 1; Sheppard and Wheeler 2020, 
p. 6).
    The best available information does not provide evidence of an 
altered wildfire regime within the beardtongues' ranges, although 
decades of fire suppression have increased the risk of high severity, 
stand-replacing wildfires (BLM 2008b, pp. 3-21). We also considered the 
exposure and impacts of wildfire to the beardtongues. One recent 
wildfire (Wolf Den Fire) occurred within the beardtongues' ranges. 
Overall, the wildfire appeared to have a low or minor negative impact 
to Graham's beardtongue, while White River beardtongue plants and 
habitat were not affected (Brunson 2012, entire). To address wildfire, 
the 2014 CA provides that the Penstemon Conservation Team will 
coordinate with land managers regarding wildfire and post-wildfire 
management activities and

[[Page 2118]]

mitigation for impacts in conservation areas. For our analysis, we 
assumed that wildfire frequency and extent in beardtongue populations 
would generally not change from current levels over the next 10 years.
Small Population Size
    Based on results of a PVA, for Graham's and White River 
beardtongues, we consider small populations to be those that have 
greater than 10 percent extinction risk (see Service 2021a, pp. 59-62). 
This threshold is equivalent to Graham's beardtongue populations with 
fewer than 67 plants and White River beardtongue populations with fewer 
than 200 individuals. Graham's beardtongue has a lower threshold than 
White River beardtongue because its populations were more stable over 
the monitoring period that informed the PVA. Populations in this size 
category are more prone to extinction from stochastic events than 
larger populations based on their life-history characteristics and 
stable demographic pattern (McCaffery 2013b, p. 1). We considered large 
populations of Graham's and White River beardtongues to be those with 
low (less than 5 percent) extinction risk, and medium populations to be 
those with moderate (6-10 percent) extinction risk. Large populations 
of Graham's beardtongue have more than 130 plants, and large White 
River beardtongue populations have more than 370 plants (Service 2021a, 
pp. 59-62; Service 2021a, p. 7, Appendix A). Graham's beardtongue has 
12 small populations and 15 large populations distributed across its 
range, and the small populations comprise less than one percent of all 
known individuals. White River beardtongue has 6 small populations and 
11 large populations distributed across its range, and the small 
populations comprise less than one percent of all known individuals. As 
part of the 2014 CA, the Penstemon Conservation Team developed 
designated conservation areas to protect large populations of Graham's 
and White River beardtongues as well as moderate and small populations 
across both species' ranges to support population connectivity. While 
not a primary driver of either species' current or future condition, we 
considered the potential cumulative impacts of small population size 
with other stressors in our analysis.
Climate Change
    Climate change has the potential to impact Graham's and White River 
beardtongues (78 FR 47590, August 6, 2013; 79 FR 46042, August 6, 
2014). We do not have a clear understanding of how Graham's and White 
River beardtongues have responded to precipitation changes, although 
plant numbers have been documented as remaining fairly stable during 
drought years. There is also no association between regional 
precipitation patterns and population demographics for either species 
(McCaffrey 2013a, p. 16). As part of the 2014 CA, BLM recently 
installed weather monitoring equipment adjacent to eight monitoring 
sites to collect local climate data in Range Units 1-5 (McCulley and 
Hornbeck 2017, p. 2; Penstemon Conservation Team 2019a, p. 8; Sheppard 
and Wheeler 2020, pp. 17-22). The data collected from weather 
monitoring can be correlated with demography data to determine basic 
species responses to climate patterns.
    Because we are not aware of a downscaled climate model for the 
range of Graham's and White River beardtongues, we used climate change 
data from the Multivariate Adaptive Constructed Analogs (MACA) website. 
We used two different emission scenarios, a stabilization emission 
scenario using Representative Concentration Pathway (RCP) 4.5 and a 
rising greenhouse gas emissions scenario using RPC 8.5 developed by the 
Intergovernmental Panel on Climate Change. The results of our 
``downscaled'' climate evaluation indicate future climate conditions 
will be warmer in all seasons under both emission scenarios (Lindstrom 
2019, entire). The difference in temperature increase between the two 
scenarios is within 3.2 [deg]F through 2070. Precipitation for all 
seasons is expected to increase under both scenarios. In order to 
evaluate a more integrated measure of the combined effect of increased 
temperature and precipitation levels, we considered a measure of 
evaporative deficit instead of precipitation alone for our predictions 
of drought conditions (Lindstrom 2019, entire), using the U.S. 
Geological Survey (USGS) National Climate Change Viewer. Both scenarios 
indicate the range of Graham's and White River beardtongues may be 
drier in the future (through 2070) compared to historical conditions 
(Service 2021b, pp. 40-41).
    Overall, climate change presents substantial uncertainty regarding 
the future environmental conditions in the range of Graham's and White 
River beardtongues, but it may place an added stress on the species and 
its habitat, particularly where other stressors are present. When we 
considered characteristics that contribute to vulnerability to climate 
change such as dispersal ability, highly specific habitat requirements, 
and ability to shift distribution in response to environmental 
conditions, Graham's and White River beardtongues would likely rank 
moderate or high on the vulnerability index at the species level (Young 
et al. 2012, pp. 133-139). Despite characteristics that make the two 
species vulnerable to climate change, our climate evaluation is too 
speculative to determine the severity of this stressor to Graham's and 
White River beardtongues at the population level. Long-lived perennial 
plants exhibit a range of drought and temperature sensitivities based 
on physiological, morphological, and inherent genetic variability 
(Warwell and Shaw 2017, p. 1205), which all contribute to a species' 
tolerance (Hoover et al. 2015, pp. 7-11). Additional information 
regarding each species' drought and temperature tolerance is needed for 
us to be able to assess the species' responses to future climate 
changes. For our analysis, we assumed that climate conditions would 
generally not change over the next 10 years from current levels in 
beardtongue populations, but may contribute to stronger effects of 
herbivory and invasive weeds to all beardtongue populations. Over a 
longer timeframe (through 2070), we expect temperatures and drought 
conditions to increase, but there is substantial uncertainty regarding 
their impact to the beardtongues.
Stressors Considered but Not Carried Forward
    We considered the potential impacts from off-highway vehicle use, 
disease, and collection. The best available information indicates that 
these are low-level stressors and do not impact the beardtongues either 
by themselves, or cumulatively with any other stressors (Service 2021a, 
p. 63).
Summary of Factors Influencing Viability
    Overall, we consider the primary drivers of the status of Graham's 
beardtongue and White River beardtongue to be energy development and 
the protections provided by the 2014 CA and other regulatory mechanisms 
on Federal and State lands. Energy development activities, including 
oil shale, tar sands, and traditional oil and gas, have collectively 
had minimal impacts to both species to date but have the greatest 
potential of the stressors we evaluated for future impacts. Other 
stressors are not expected to have population- or species-level impacts 
by themselves but may have the potential for cumulative

[[Page 2119]]

impacts on the species when considered together with energy development 
and other stressors. The protections provided by the 2014 CA and other 
regulatory mechanisms are expected to reduce the negative effect of 
energy development on the beardtongues' population resiliency.

Summary of Current Condition

    In our Biological Report of current condition (Service 2021a, 
entire), we describe Graham's and White River beardtongues' viability 
by characterizing their current condition in terms of the 3Rs. We 
evaluate resiliency at the population level, and redundancy and 
representation at the species level. This analysis is described in 
detail in the Biological Report (Service 2021a, entire), and is briefly 
summarized here.
    We evaluated the current resiliency of each beardtongue population 
by scoring relevant demographic (population size) and habitat factors 
for the species for which information is available (Service 2021a, pp. 
66-70). For population size, we incorporated two factors, population 
extinction risk (based on a PVA) and the presence of high-density 
clusters of plants within populations, into our calculation. For 
habitat, we incorporated three factors, pollinator habitat quality 
(measured as percent nonnative plant cover), pollinator habitat area, 
and pollinator habitat loss, into our calculation. We included 
pollinator habitat area because this factor is associated with plant 
abundance and biodiversity (Krauss et al. 2004, entire) and may change 
in a predictable way to estimate future population size. Each 
population's overall resiliency score is the average of all individual 
factor scores, which translates to an overall current condition 
category of low, moderate, or good.

Graham's Beardtongue

    Fourteen Graham's beardtongue populations are in good current 
condition (i.e., the most resilient) due to their large population size 
and habitat quality ranks (Service 2021a, pp. 68-69). These factors 
likely provide Graham's beardtongue the ability to withstand stochastic 
events such as drought or wildfire. The remaining 13 populations are in 
moderate condition based on the habitat and demographic factors 
contributing to resiliency (Service 2021a, pp. 68-69). The moderate 
condition of these populations may result in a lower ability to 
withstand stochastic events than the populations in good condition. The 
low levels of habitat loss to date have not changed the overall current 
condition of any population. Only one population (population 11) had a 
reduction in the overall condition because of higher weed presence; the 
remaining populations retain the same condition as they did 
historically (Service 2021a, pp. 68-69).
    Unlike many other narrow endemic species, the redundancy of 
Graham's beardtongue is quite high despite its limited geographical 
range. The species' 27 populations are spread across the Uinta Basin on 
different topographic features, which likely provides the ability to 
withstand more localized catastrophic events (e.g., wildfire), and may 
provide a limited ability to withstand rangewide catastrophic events 
(e.g., drought) (Service 2021a, pp. 70-72). Maintaining redundancy to 
reduce the risk from catastrophic events is dependent upon maintaining 
sufficiently resilient populations of Graham's beardtongue in 
topographically diverse habitat conditions.
    We do not have meaningful information on the genetic diversity of 
Graham's beardtongue. Therefore, we considered other types of 
representative diversity, such as population size and ecological 
settings, that could indicate some ability to adapt to change within 
the species' range (Service 2021a, pp. 72-77). Graham's beardtongue has 
15 large populations distributed across its range with at least 1 large 
population within each of the five range units. There are three medium 
populations within the two western-most range units; the remaining nine 
populations are small. We assume the 15 large populations contain the 
majority of genetic variation within the total population because they 
contain 99.5 percent of all individuals (Service 2021a, p. 73). 
Graham's beardtongue populations and metapopulations occur in a high 
diversity of ecological settings, suggesting a high level of genetic 
variation within each range unit (Service 2021a, p. 76). In addition, 
the species exhibits a gradient of morphological and phenological 
differences across its range. Preserving the species' representation 
requires maintaining medium and large populations, connectivity between 
populations, and a diversity of ecological settings across its range. 
The current distribution is the same as the historical distribution, 
and the best available information does not indicate that a reduction 
in genetic diversity or connectivity among populations has occurred.
    Overall, Graham's beardtongue exhibits high levels of resiliency, 
redundancy, and representation that have allowed populations to persist 
throughout the species' range. The species contains a high number of 
populations in good or moderate condition, and levels of redundancy and 
representation are similar to its historical condition. Graham's 
beardtongue is stable despite localized weed encroachment and some loss 
of occupied habitat and pollinator habitat. The current condition of 
Graham's beardtongue populations is a direct result of the low levels 
of habitat loss and degradation to date and habitat protections 
afforded to the species under the 2014 CA. For further explanation of 
our analysis of the current condition of Graham's beardtongue, see our 
Biological Report (Service 2021a, pp. 63-80).

White River Beardtongue

    Seven White River beardtongue populations are in good current 
condition (i.e., the most resilient) due to their large population size 
and habitat factors (Service 2021a, pp. 68-70). These factors likely 
provide White River beardtongue the ability to withstand stochastic 
events such as drought or wildfire. There are nine populations in 
moderate condition based on the habitat factors (habitat area and 
quality) contributing to resiliency (Service 2021a, pp. 68-70). The 
moderate condition of these populations may result in a lower ability 
to withstand stochastic events compared to populations in good 
condition. One population (Population 8) is in low condition and is the 
least likely to withstand stochastic events (Service 2021a, pp. 68-70).
    The low overall level of pollinator habitat loss for all 
populations to date does not change the overall current condition of 
any population because habitat loss does not exceed the low habitat 
loss condition threshold of five percent habitat loss, and effects to 
populations remain small and localized. Two populations (Populations 8 
and 13) had a reduction in their overall condition because of higher 
weed presence; the remaining 15 populations retain the same condition 
as they did historically (Service 2021a, pp. 68-70).
    Unlike many other narrow endemic species, the redundancy of White 
River beardtongue is fairly high despite its limited geographical range 
(Service 2021a, pp. 70-72). The species includes 17 populations spread 
across the Uinta Basin on different topographic features, which likely 
provides the ability to withstand more localized catastrophic events 
(e.g., wildfire) and may provide a limited ability to withstand 
rangewide catastrophic events (e.g., drought).

[[Page 2120]]

Maintaining redundancy to reduce the risk of catastrophic events is 
dependent upon maintaining sufficiently resilient populations of White 
River beardtongue in topographically diverse habitat conditions.
    We considered population size and ecological settings that could 
indicate some ability to adapt to change within the species' range 
(Service 2021a, pp. 72-77). White River beardtongue has 11 large 
populations distributed across its range with at least 1 large 
population within each of the five range units. The remaining six 
populations are small. We assume these 11 large populations contain the 
majority of genetic variation within the total population, because they 
contain 99.7 percent of all individuals (Service 2021a, p. 76). There 
is a high diversity of ecological settings within White River 
beardtongue metapopulations, suggesting a high level of genetic 
variation within each range unit. One White River beardtongue range 
unit has a distinctly different composition of vegetation types than 
the other range units, which we consider a different ecological setting 
for the species (Service 2021a, p. 76). We assume this is an indication 
that this range unit has a slightly different genetic composition than 
the other range units. The preliminary genetic information and opinions 
from our expert panel support this assumption (Stevens 2019, 
attachments a, b, c; Service 2017a, p. 4). Preserving the species' 
representation requires maintaining large populations, connectivity 
between populations, and a diversity of ecological settings across its 
range. The current distribution is the same as the historical 
distribution, and the best available information does not indicate that 
a reduction in genetic diversity or connectivity among populations has 
occurred.
    Overall, White River beardtongue exhibits high levels of 
resiliency, redundancy, and representation, which have allowed 
populations to persist throughout the species' range. The species 
contains a high number of populations in good or moderate condition, 
and levels of redundancy and representation are similar to its 
historical condition. White River beardtongue is stable despite 
localized weed encroachment and some loss of pollinator habitat. The 
current condition of White River beardtongue populations is a direct 
result of the low levels of habitat loss and degradation to date and 
habitat protections afforded to the species under the 2014 CA. For 
further explanation of our analysis of the current condition of White 
River beardtongue, see our Biological Report (Service 2021a, pp. 63-
80).

Summary of Future Condition

    Using the 3Rs, we evaluated the future viability of the 
beardtongues based on the presence of multiple (redundancy), self-
sustaining (resiliency) populations distributed across the range of the 
species, and their contributions to adaptive capacity (representation) 
in the face of changing environmental conditions. We relied on our 
characterization of each species' current condition, stressors, and 
effects of stressors as the baseline from which to evaluate future 
changes to those factors considered important to the beardtongues 
(Service 2021a, entire). Our analysis of the projected future condition 
of Graham's and White River beardtongues is described in detail in our 
Biological Report of future condition (Service 2021b, entire), and is 
briefly summarized here.
    Based on input received from Federal and State agencies, private 
industry, and the best available information, we developed two 
plausible future scenarios--moderate and high energy development 
(Service 2021b, pp. 48-56). We used reliable projections of future 
events and the future locations of stressors based on the best 
available information and expert opinion. Published literature 
evaluates energy development at a coarser scale (e.g., the Uintah 
Basin, State of Utah, or county-level) than what we needed for our 
analysis within the beardtongues' ranges. Therefore, we relied on 
expert opinion to evaluate energy development specifically within the 
ranges of the two species and assign likelihoods to future exploration 
and development activities (Service 2021b, pp. 12, 13).
    Based on this information, our two scenarios considered impacts to 
the beardtongues through 2030, because we have sufficient information 
to project out to 10 years for energy development (oil shale, tar 
sands, and oil and gas development), which is the primary future 
stressor for the beardtongues (Service 2021b, p. 49). Beyond 10 years, 
there is too much uncertainty about the fluctuating market price of oil 
and gas, the possibility of future technological advances that could 
lower extraction costs and favor certain industries, and the results of 
planned oil exploration to project the level or distribution of energy 
development within the beardtongues' populations and ranges, such that 
projections would become speculative (Service 2019, entire; Service 
2020, entire). Expert panel likelihood estimates and the best available 
information from published literature and technical reports informed 
our 10-year energy development (oil shale, tar sands, and oil and gas 
development) projection timeframe. Our 10-year energy development 
timeframe is generally consistent with long-term economic forecasts for 
oil shale, tar sands, and traditional oil and gas that are based on the 
market price of oil and natural gas (Service 2021b, pp. 17, 25, 33, 
34). In addition, future oil exploration and development within the 
beardtongues' ranges will depend of the results of planned exploration 
within Uintah County (Service 2021b, pp. 32--35). We note that we do 
have certainty through 2034 that the protections of the 2014 CA will 
remain in place, which will limit where energy development could occur. 
For more information on how these projection timeframes relate to our 
evaluation of the ``foreseeable future'', see Consideration of 
Foreseeable Future below.
    In the locations where energy stressors occurred for the two 
scenarios, our analysis included the following assumptions: Commercial 
development activities for oil shale and tar sands will occur in the 
next 10 years on non-Federal (private and state) lands within each 
forecast; and a total loss of plants and habitat will occur where oil 
shale and tar sands development are projected (Service 2021b, pp. 15-
31; 49-56). These assumptions allowed us to evaluate potential worst-
case impacts from energy development in combination with other 
stressors, to bracket the full range of impacts to the beardtongues 
that may occur, because actual future impacts may range anywhere from 
their current condition to the future scenarios evaluated here, or may 
fall in between. We did not develop a scenario that considered 
``exploration-only'' activities for oil shale and tar sands, with a 
smaller surface disturbance extent, even though this would also be a 
plausible future forecast for oil shale and tar sands, because the 
impacts under an exploration-only scenario would fall in between the 
current condition and the energy development scenarios we developed. 
Our evaluation of effects from energy development accounted for the 
protections afforded to the beardtongues from the 2014 CA that are in 
place through 2034.
    For the two future scenarios, we forecasted the species' biological 
condition based on conservation efforts and the following stressors: 
Oil shale, tar sands, and traditional oil and gas exploration and 
development activities; road construction and maintenance; herbivory; 
invasive weeds; small

[[Page 2121]]

population size; and climate change. Our future scenarios varied based 
on two forecasts for oil shale (moderate, high). For each of the other 
stressors (tar sands, traditional oil and gas, road construction and 
maintenance, herbivory, invasive weeds, small population size, and 
climate change) we developed only one future forecast (these forecasts 
were used in both future scenarios) because their future, plausible 
extents are not expected to vary much within the beardtongues' ranges 
independent of the oil shale stressor (Service 2021b, pp. 49-56).
    In the moderate energy development scenario (Scenario 1), we 
projected that oil shale exploration and commercial development would 
occur on lands identified as having a high potential for both 
activities (Service 2021b, pp. 49-52). The effects of herbivory and 
invasive weeds may increase in populations that overlap with energy 
development. Climate change may increase the effects from herbivory and 
invasive weeds to all beardtongue populations. In the high energy 
development scenario (Scenario 2), we projected that oil shale 
exploration and commercial development would occur over a larger area 
that included the same lands as the moderate scenario, plus other lands 
identified as likely or about as likely as not to support these 
activities (Service 2021b, pp. 52-55). The potential effects of the 
other stressors to all beardtongue populations remained the same as 
evaluated for the moderate energy development scenario.
    Under each of these future scenarios, we assessed future resiliency 
by evaluating relevant habitat and demographic factors to calculate an 
overall condition score for each plant population. We evaluated 
population size, habitat area, habitat quality, and habitat loss to 
project the future resiliency of each population. Based on the results 
of these evaluations, we rated population condition as good, moderate, 
low, or extirpated. To assess future redundancy, we evaluated the 
projected number and distribution of populations within the species' 
range relative to the current condition. To assess future 
representation, we evaluated the projected demographic (population 
size) and ecological (ecological settings) surrogates of genetic 
diversity relative to the current condition. For more detailed 
information on our methodology for evaluating future conditions, see 
the Biological Report (Service 2021b, pp. 49-56).

Graham's Beardtongue

    Under the moderate energy development scenario, oil shale and 
traditional oil and gas are the main stressors for Graham's 
beardtongue, and these stressors are projected to result in loss of 
individual plants and habitat in the center of the species' range 
(Service 2021b, Figure 11, pp. 50, 56). In this scenario, there is a 
projected loss of 34 percent of the total number of plants from energy 
development, with a remaining total population size of 37,350 
individuals in 24 populations (Service 2021b, p. 57). Remaining 
occupied habitat and pollinator habitat are projected to be 7,642 ac 
(3,093 ha) and 72,455 ac (29,321 ha), respectively. The main stressors 
result in the extirpation of three populations and a decline in the 
condition of four populations compared to their current condition. The 
current population condition is maintained in the other 20 populations. 
The species continues to occupy the extent of its current range, and 
all five range units continue to support populations in good or 
moderate condition. Fourteen populations in good and moderate condition 
are large in size and have a low extinction risk (Service 2021b, pp. 
57-58).
    Despite the extirpation of some populations under the moderate 
energy development scenario, levels of redundancy remain high, with 
Graham's beardtongue maintaining 24 populations (Service 2021b, p. 60). 
Our evaluation of representation under this scenario indicates that 
Graham's beardtongue maintains a level of ecological diversity within 
the 24 remaining populations that is similar to its current condition 
and should have the adaptive capacity to tolerate projected, future 
climate and habitat conditions (Service 2021b, p. 60). The best 
available information does not indicate that the projected loss of the 
three Graham's beardtongue populations and projected plant loss in 
other populations would result in significant impacts to Graham's 
beardtongue's representation.
    Under the high energy development scenario, the main stressors 
remain the same for Graham's beardtongue, but oil shale impacts result 
in more extensive plant and habitat loss in the center of the species' 
range than in the moderate energy development scenario (Service 2021b, 
Figure 13, pp. 53, 60-62). In this scenario, there is a projected loss 
of 45 percent of the total number of plants from energy development, 
with a remaining total population size of 30,794 individuals in 24 
populations. Remaining occupied habitat and pollinator habitat are 
projected to be 6,037 ac (2,443 ha) and 63,580 ac (25,730 ha), 
respectively. The main stressors result in the extirpation of three 
populations and a decline in the condition of six populations compared 
to their current condition. The current population condition is 
maintained in the other 18 populations. Fourteen populations in good 
and moderate condition are large in size and have a low extinction 
risk. The species continues to occupy the extent of its current range, 
and all five range units continue to support populations in good or 
moderate condition (Service 2021b, pp. 60-62).
    Despite the extirpation of populations, levels of redundancy remain 
high with Graham's beardtongue maintaining 24 populations (Service 
2021b, p. 64). Our evaluation of representation indicates that Graham's 
beardtongue maintains a level of ecological diversity within the 24 
remaining populations that is similar to its current condition and 
should have the adaptive capacity to tolerate future climate and 
habitat conditions (Service 2021b, p. 64). The best available 
information does not indicate that the projected loss of the three 
Graham's beardtongue populations and projected plant loss in other 
populations would result in significant impacts to Graham's 
beardtongues' representation.

White River Beardtongue

    Under the moderate energy development scenario, oil shale is the 
main stressor for White River beardtongue, and this stressor is 
projected to result in loss of individual plants and habitat in the 
center of the species' range (Service 2021b, Figure 12, pp. 51, 57-59). 
In this scenario, there is a projected loss of 1 percent of the total 
number of plants from energy development, with a remaining total 
population size of 29,686 individuals in 16 remaining populations. 
Remaining occupied habitat and pollinator habitat are projected to be 
3,218 ac (1,302 ha) and 26,959 ac (10,910 ha), respectively (Service 
2021b, pp. 57-59). The main stressor results in the extirpation of one 
population and a decline in the condition of one population compared to 
their current condition. The current population condition is maintained 
in the other 15 populations. The species continues to occupy the extent 
of its current range, and all five range units continue to support 
populations in good or moderate condition. Eleven populations in good 
and moderate condition are large in size and have a low extinction risk 
(Service 2021b, pp. 57-59).
    Despite the extirpation of one population under the moderate energy 
development scenario, levels of redundancy remain high with White

[[Page 2122]]

River beardtongue maintaining 16 populations (Service 2021b, p. 60). 
Our evaluation of representation indicates that White River beardtongue 
maintains a level of ecological diversity within the 16 remaining 
populations that is similar to its current condition and should have 
the adaptive capacity to tolerate future climate and habitat conditions 
(Service 2021b, p. 60). The best available information does not 
indicate that the projected loss of the one White River beardtongue 
population and projected plant loss in other populations would result 
in significant impacts to White River beardtongue's representation.
    Under the high energy development scenario, the main stressor 
remains the same for White River beardtongue, but oil shale impacts 
result in more extensive plant and habitat loss in the center of the 
species' range than in the moderate energy development scenario 
(Service 2021b, Figure 14, pp. 54, 61-63). In this scenario, there is a 
projected loss of 24 percent of the total population from energy 
development, with a remaining total population size of 22,695 
individuals in 15 populations. Remaining occupied habitat and 
pollinator habitat are projected to be 2,317 ac (938 ha) and 20,099 ac 
(8,134 ha), respectively (Service 2021b, pp. 61-63). The main stressor 
results in the extirpation of two populations and a decline in the 
condition of two populations compared to their current condition. The 
current population condition is maintained in the other 13 populations. 
Nine populations in good and moderate condition are large in size and 
have a low extinction risk. The species continues to occupy the extent 
of its current range, and all five range units continue to support 
populations in good or moderate condition (Service 2021b, pp. 61-63).
    Despite the extirpation of populations, levels of redundancy remain 
high with White River beardtongue maintaining 15 populations (Service 
2021b, p. 64). Our evaluation of representation indicates that White 
River beardtongue maintains a level of ecological diversity within the 
15 remaining populations that is similar to its current condition and 
should have the adaptive capacity to tolerate future climate and 
habitat conditions (Service 2021b, p. 64). The best available 
information does not indicate that the projected loss of the two White 
River beardtongue populations and projected plant loss in other 
populations would result in significant impacts to White River 
beardtongue's representation.
    The 2014 CA provides protections for the beardtongues on Federal 
and State lands until 2034. During this time, the beardtongues are 
afforded the same level of protections on Federal and State lands 
within designated conservation areas. The 2014 CA identifies 42,993 ac 
(17,399 ha) of designated conservation areas that protect 41 percent of 
the Graham's beardtongue population in 13 populations, and 66 percent 
of the White River beardtongue population in 11 populations (Service 
2021b, pp. 43-46). Within designated conservation areas, protections 
include an avoidance buffer of 300 ft (91.4 m) between disturbance and 
beardtongue plants, as well as surface disturbance caps to restrict 
development. Surface disturbance caps would allow a limited amount of 
new construction for roads and traditional oil and gas development but 
would prohibit future oil shale and tar sand exploration and 
development (Service 2021b, pp. 43-46).
    The beardtongues are also afforded protections on Federal lands 
outside of designated conservation areas, including a 300-ft (91.4-m) 
avoidance buffer, surface disturbance restrictions on steep slopes, 
areas that are unavailable for leasing or have NSO stipulations, and 
designated ACECs (Service 2021b, pp. 47-48). In total, the 2014 CA 
designated conservation areas and other conservation measures on 
Federal lands provide protections to 51 percent and 76 percent of the 
Graham's beardtongue and White River beardtongue total population, 
respectively (Service 2021b, p. 48).

Determination of Species Status

    Section 4 of the Act (16 U.S.C. 1533) and its implementing 
regulations (50 CFR part 424) set forth the procedures for determining 
whether a species meets the definition of an endangered species or a 
threatened species. The Act defines an endangered species as a species 
that is ``in danger of extinction throughout all or a significant 
portion of its range,'' and a threatened species as a species that is 
``likely to become an endangered species within the foreseeable future 
throughout all or a significant portion of its range.'' The Act 
requires that we determine whether a species meets the definition of 
endangered species or threatened species because of any of the 
following 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.
    Since the publication of the August 6, 2013, proposed listing rule 
(78 FR 47590), and the subsequent reinstatement of that proposed rule 
following litigation, we prepared a comprehensive assessment of the 
current and future status of Graham's beardtongue and White River 
beardtongue as presented in the Biological Reports (Service 2021a, 
entire; 2021b, entire). The Biological Reports reexamined the threats 
identified in the 2013 proposed listing rule (energy exploration and 
development, as well as the cumulative impacts of livestock grazing, 
invasive weeds, small populations sizes, and climate change) using 
concepts from the Service's SSA framework (Service 2016, entire; Smith 
et al. 2018, entire). The Biological Reports also incorporate new 
information into our analysis that has become available since 2013, 
including updated monitoring information and the final 2014 CA and its 
2018 addendum.
    We have carefully assessed the best scientific and commercial 
information available regarding the past, present, and future threats 
to Graham's and White River beardtongues, including: Energy exploration 
and development: Oil shale, tar sands, and traditional oil and gas 
drilling (Factor A); road construction (Factor A); herbivory (Factor 
C); invasive weeds (Factor A); small population size (Factor E); and 
climate change (Factors A and E). We also evaluated how existing 
regulatory mechanisms (Factor D) and other conservation measures 
(primarily the 2014 CA and 2018 addendum) may lessen the impacts of 
these stressors. The best available information does not indicate that 
overutilization (Factor B) is a threat to either beardtongue species.

Consideration of Cumulative Effects

    Threats can work in concert with one another to cumulatively create 
conditions that may impact the Graham's and White River beardtongues or 
their habitat beyond the scope of each individual threat. We note that 
by using concepts from the SSA framework to guide our analysis of the 
scientific information documented in the Biological Reports, we have 
not only analyzed individual effects on the species, but we have also 
analyzed their potential cumulative effects. We incorporate the 
cumulative effects into our analysis when we characterize the current 
and future condition of the species. To assess the current and future 
condition of the species, we undertake an iterative analysis that 
encompasses and incorporates the threats individually and then 
accumulates and evaluates the effects of all the factors

[[Page 2123]]

that may be influencing the species, including threats and conservation 
efforts. Because our analysis considers not just the presence of the 
factors, but to what degree they collectively influence risk to the 
entire species, our assessment integrates the cumulative effects of the 
factors and replaces a standalone cumulative effects analysis.

Consideration of Foreseeable Future

    In considering the foreseeable future for Graham's beardtongue and 
White River beardtongue, we considered the available data regarding the 
factors that may influence both species into the future, including 
stressors, and conservation efforts or regulatory mechanisms that may 
provide protections. The primary driver of both species' condition into 
the future is energy development. We are able to make reliable 
predictions about the range of plausible future impacts of oil shale, 
tar sands, and traditional oil and gas through approximately 2030. 
Beyond 2030, based on input from experts, the impacts of energy 
development become too speculative to predict. Other stressors, 
including roads, livestock grazing, invasive weeds, and small 
population size, exert a cumulative effect on the beardtongues where 
they occur with energy development, and, therefore, we are similarly 
able to reliably predict their impacts on the species through 
approximately 2030. Climate change has the potential to exacerbate the 
effect of other stressors, including livestock grazing and invasive 
weeds, where they are present on the landscape. We have information on 
climate change, including projected changes in temperature, 
precipitation, and evaporative deficit out to 2070. However, we are not 
able to make reliable predictions about the species' responses to these 
changes out to 2070, since the species' expected responses to these 
variables are uncertain, and will depend on the presence and impacts of 
other stressors.
    We also have information on various timescales to make reliable 
predictions about future protections that may be in place for both 
Graham's and White River beardtongues. The 2014 CA provides protections 
through designated conservation areas on Federal and State lands 
through 2034. Regulatory mechanisms are in place to provide for the 
State conservation areas (Utah Code 53C-2-202 and Utah Administrative 
Code R850-150) through 2034. Federal regulatory mechanisms, including a 
BLM sensitive species designation, and BLM RMP designations and 
stipulations, provide protections for the species through at least 
2038. The 2014 CA conservation areas on private lands are expected to 
expire sooner, in 2029. A Uintah County Ordinance that provides for 
those areas also expires in 2029. Therefore, we did not include these 
private land conservation areas in our analysis of future conditions.
    Overall, the primary drivers of the future status of Graham's 
beardtongue and White River beardtongue are energy development and the 
protections provided by the 2014 CA and other regulatory mechanisms on 
Federal and State lands. We have information to make reliable 
predictions about these factors, and the species' responses to them, 
through: 2030 for the threat of energy development, 2034 for the 
protections of the 2014 CA on Federal and State conservation areas, and 
2038 for regulatory mechanisms on BLM lands. Therefore, the foreseeable 
future for this determination ranges from approximately 2030 to 2034, 
for the stressors and 2014 CA protections included in our future 
scenarios, to approximately 2038 for BLM regulatory mechanisms.

Graham's Beardtongue: Determination of Status Throughout All of Its 
Range

    Our evaluation of the current condition of Graham's beardtongue 
found that there are currently tens of thousands of individual plants 
distributed across many populations that have good or moderate 
resilience to stochastic events. The species currently has a sufficient 
level of redundancy and representation to withstand catastrophic events 
and adapt to changes, with populations distributed across five range 
units. While some stressors have impacted individuals in localized 
areas, none are currently having population-level impacts individually 
or cumulatively. Therefore, we find that the species is not in danger 
of extinction throughout all of its range.
    Our evaluation of the projected future condition of Graham's 
beardtongue found that there is very high uncertainty about the future 
likelihood of oil shale development. The future condition of Graham's 
beardtongue in 2030 may range anywhere from its current condition to 
the impacts projected in the high energy development scenario. However, 
the impacts projected under the high energy development scenario 
represent a worst-case scenario, which we expect is less likely to 
occur than the impacts projected under the moderate energy development 
scenario, or a continuation of current conditions. Although unlikely, 
even if we assume the high energy development scenario were to occur, 
the impacts of the stressors on Graham's beardtongue would be limited 
to three range units. Those three impacted range units would still have 
several populations in good or moderate condition, and over 30,000 
individual plants would remain. In this scenario, Graham's beardtongue 
would also retain over 6,000 ac (2,428 ha) of occupied habitat and 
63,000 ac (25,495 ha) of pollinator habitat. The 2014 CA would cap the 
total level of habitat that could be impacted within the foreseeable 
future. Therefore, even in this worst-case scenario, we anticipate that 
Graham's beardtongue would retain sufficient levels of resiliency, 
redundancy, and representation in the foreseeable future. Thus, after 
assessing the best available information, we conclude that the Graham's 
beardtongue is not in danger of extinction throughout all of its range 
nor is it likely to become so in the foreseeable future.

Graham's Beardtongue: Determination of 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 Graham's beardtongue is not in 
danger of extinction or likely to become so in the foreseeable future 
throughout all of its range, we now consider whether it may be in 
danger of extinction or likely to become so in the foreseeable future 
in a significant portion of its range--that is, whether there is any 
portion of the species' range for which it is true that both (1) the 
portion is significant; and (2) the species is in danger of extinction 
now or likely to become so in the foreseeable future in that portion. 
Depending on the case, it might be more efficient for us to address the 
``significance'' question or the ``status'' question first. We can 
choose to address either question first. Regardless of which question 
we address first, if we reach a negative answer with respect to the 
first question that we address, we do not need to evaluate the other 
question for that portion of the species' range.
    In undertaking this analysis for the Graham's beardtongue, we 
choose to address the status question first--we consider information 
pertaining to the geographic distribution of both the species and the 
threats that the species faces to identify any portions of the range 
where the species is endangered or threatened. For the Graham's 
beardtongue, we considered whether the threats are geographically 
concentrated in any portion of the species' range at a biologically 
meaningful scale. We

[[Page 2124]]

examined the following threats: Energy development (oil shale, tar 
sands, and traditional oil and gas drilling) and the additional 
cumulative impacts of road construction, herbivory, invasive weeds, 
small population size, and climate change with energy development 
(Service 2021a, entire; 2021b, entire). We acknowledge that there are 
three range units (Units 2, 3, and 4) with potentially greater levels 
of impacts projected from oil shale in the foreseeable future, although 
the worst-case impacts of the high energy development scenario are less 
likely to occur than the impacts under the moderate energy development 
scenario or a continuation of current conditions. However, even if 
these worst-case projected impacts were to occur in Range Units 2, 3, 
and 4, several populations would remain in good or moderate condition 
in Range Units 2 and 3, and the one population in Range Unit 4 would 
remain in good condition. Based on the resiliency of these remaining 
populations, and their spread across these range units, we expect that 
adequate levels of resiliency, redundancy, and representation would 
remain in these units to protect again stochastic and catastrophic 
events and to adapt to future changes, and so, this portion of the 
range would not meet the definition of endangered or threatened. 
Therefore, no portion of the species' range can provide a basis for 
determining that the species is in danger of extinction now or likely 
to become so in the foreseeable future in a significant portion of its 
range, and we find 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 is consistent with the courts' holdings in

White River Beardtongue: Determination of Status Throughout All of Its 
Range

    Our evaluation of the current condition of White River beardtongue 
found that there are currently nearly 30,000 individual plants 
distributed across many populations that have good or moderate 
resilience to stochastic events. The species currently has a sufficient 
level of redundancy and representation to withstand catastrophic events 
and adapt to changes, with populations distributed across five range 
units. In addition, the recent discovery of a new population in the 
Book Cliffs has expanded the species' known range. While some stressors 
have impacted individuals and habitat in localized areas, none are 
currently having population-level impacts. Therefore, we find that the 
species is not in danger of extinction throughout all of its range.
    Our evaluation of the projected future condition of White River 
beardtongue found that there is very high uncertainty around the future 
of oil shale development. The future condition of White River 
beardtongue in 2030 may range anywhere from its current condition, to 
the impacts projected in the high energy development scenario. However, 
the impacts projected under the high energy development scenario 
represent a worst-case scenario, which we expect is less likely to 
occur than the impacts projected under the moderate energy development 
scenario, or a continuation of current conditions. Although unlikely, 
even if we assume the high energy development scenario were to occur, 
the impacts of the stressors on White River beardtongue are projected 
to be limited. Under this worst-case scenario, we expect that White 
River beardtongue would retain over 75 percent of individual plants and 
maintain the resiliency of the large populations. The 2014 CA is 
expected to protect the majority (66 percent) of plants across 11 
populations into the foreseeable future. We also expect sufficient 
levels of redundancy and representation to remain across the range 
units, even though 2 out of 17 populations could be lost. Therefore, 
even in this worst-case scenario, we anticipate that White River 
beardtongue would retain sufficient levels of resiliency, redundancy, 
and representation in the foreseeable future. Thus, after assessing the 
best available information, we conclude that White River beardtongue is 
not in danger of extinction throughout all of its range nor is it 
likely to become so in the foreseeable future.

White River Beardtongue: Determination of 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 White River beardtongue is not in 
danger of extinction or likely to become so in the foreseeable future 
throughout all of its range, we now consider whether it may be in 
danger of extinction or likely to become so in the foreseeable future 
in a significant portion of its range--that is, whether there is any 
portion of the species' range for which it is true that both (1) the 
portion is significant; and (2) the species is in danger of extinction 
now or likely to become so in the foreseeable future in that portion. 
Depending on the case, it might be more efficient for us to address the 
``significance'' question or the ``status'' question first. We can 
choose to address either question first. Regardless of which question 
we address first, if we reach a negative answer with respect to the 
first question that we address, we do not need to evaluate the other 
question for that portion of the species' range.
    In undertaking this analysis for the White River beardtongue, we 
choose to address the status question first--we consider information 
pertaining to the geographic distribution of both the species and the 
threats that the species faces to identify any portions of the range 
where the species is endangered or threatened. For the White River 
beardtongue, we considered whether the stressors are geographically 
concentrated in any portion of the species' range at a biologically 
meaningful scale. We examined the following stressors: Energy 
development (oil shale, tar sands, and traditional oil and gas 
drilling) and the additional cumulative impacts of road construction, 
herbivory, invasive weeds, small population size, and climate change 
with energy development (Service 2021a, entire; 2021b, entire). All of 
these potential stressors are relatively evenly distributed 
geographically throughout the range of the White River beardtongue. Our 
analysis projected that small areas of disturbance will occur within 
most range units but are expected to be spread throughout the range. We 
found no concentration of stressors in any portion of the White River 
beardtongue's range at a biologically meaningful scale. Therefore, no 
portion of the species' range can provide a basis for determining that 
the species is in danger of extinction now or likely to become so in 
the foreseeable future in a significant portion of its range, and we 
find 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 is consistent with the courts' holdings in Desert Survivors v. 
Department of the Interior, No. 16-cv-01165-JCS, 2018 WL 4053447 (N.D. 
Cal. Aug. 24, 2018), and Center for Biological Diversity v. Jewell, 248 
F. Supp. 3d 946, 959 (D. Ariz. 2017).

Determination of Status

    We have reviewed the best available scientific and commercial 
information

[[Page 2125]]

regarding the past, present, and future threats to the Graham's 
beardtongue and White River beardtongue, and we have determined that 
these species do not meet the definition of an ``endangered species'' 
or a ``threatened species'' in accordance with sections 3(6) and 3(20) 
of the Act. Because of this determination, we are withdrawing our 
August 6, 2013, proposed rule to list the Graham's beardtongue and 
White River beardtongue as threatened species (78 FR 47590). 
Accordingly, we are also withdrawing our August 6, 2013, proposed rule 
to designate critical habitat for the species (78 FR 47832).
