Endangered and Threatened Wildlife and Plants; Removing 
Bradshaw's Lomatium (Bradshaw's lomatium) From the Federal List of 
Endangered and Threatened Plants

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Proposed rule

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

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), propose to 
remove Bradshaw's lomatium (Bradshaw's lomatium, also known as 
Bradshaw's desert parsley), a plant found in western Oregon and 
southwestern Washington, from the Federal List of Endangered and 
Threatened Plants due to recovery. Our review of the best available 
scientific and commercial data indicates that the threats to Bradshaw's 
lomatium have been eliminated or reduced to the point that the species 
no longer meets the definition of an endangered or threatened species 
under the Endangered Species Act of 1973, as amended (Act). We request 
information and comments from the public regarding this proposed rule 
and the draft post-delisting monitoring plan for Bradshaw's lomatium.

Information Requested

Public Comments

    Any final action resulting from this proposed rule will be based on 
the best scientific and commercial data available and be as accurate as 
possible. Therefore, we request comments or information from other 
concerned governmental agencies, Tribes, the scientific community, 
industry, or other interested parties concerning this proposed rule. 
The comments that will be most useful and likely to influence our 
decisions are those supported by data or peer-reviewed studies and 
those that include citations to, and analyses of, applicable laws and 
regulations. Please make your comments as specific as possible and 
explain the basis for them. In addition, please include sufficient 
information (such as scientific journal articles or other publications) 
with your comments to allow us to authenticate any scientific or 
commercial data you reference or provide. In particular, we seek 
comments concerning the following:
    (1) Reasons why we should or should not remove Bradshaw's lomatium 
from the Federal List of Endangered and Threatened Plants (i.e., 
``delist'' the species under the Act, 16 U.S.C. 1531 et seq.).
    (2) New biological or other relevant data concerning any threat (or 
lack thereof) to Bradshaw's lomatium and any existing regulations that 
may be addressing these or any of the stressors to the species 
discussed here.
    (3) New information concerning the population size or trends of 
Bradshaw's lomatium.
    (4) New information on the current or planned activities within the 
range of Bradshaw's lomatium that may either adversely affect or 
benefit the plant.

this proposal, if requested, and announce the date, time, and place of 
the hearing, as well as how to obtain reasonable accommodations, in the 
Federal Register and local newspapers at least 15 days before the 
hearing.

Peer Review

    In accordance with our joint policy on peer review published in the 
Federal Register on July 1, 1994 (59 FR 34270), we sought the expert 
opinions of four appropriate and independent specialists with knowledge 
of the biology and ecology of Bradshaw's lomatium regarding the species 
status assessment report (Service 2018; see Status Assessment for 
Bradshaw's lomatium, below) that forms the basis for our 5-year review 
and this proposed rule. The purpose of peer review is to ensure that 
our determination regarding the status of the species under the Act is 
based on scientifically sound data, assumptions, and analyses. We 
received feedback from three of the four peer reviewers contacted; 
their comments and corrections have been incorporated into the species 
status assessment report, as appropriate.

Background

Status Assessment for Bradshaw's Lomatium

    A thorough review of the taxonomy, life history, and ecology of 
Bradshaw's lomatium is presented in the document ``Species Status 
Assessment Report for Bradshaw's lomatium (Lomatium bradshawii (Rose 
ex. Math.) Mathias & Constance) Version 1.0'' (hereafter ``species 
status report''; Service 2018), which is available at https://www.regulations.gov in Docket No. FWS-R1-ES-2019-0013, under Supporting 
Documents. The species status report documents the results of our 
comprehensive biological status review for Bradshaw's lomatium, and has 
undergone peer review. The species status report does not represent any 
decision by the Service regarding the status of Bradshaw's lomatium 
under the Act. It does, however, provide the scientific basis that 
informed our most recent 5-year review, which resulted in a 
recommendation that the species should be removed from the List. The 
species status report also serves as one of the bases for this proposed 
rule and our regulatory decision, which involves the further 
application of standards within the Act and its implementing 
regulations and policies.
    In this proposed rule, we present only a summary of the key results 
and conclusions from the species status report; the full report is 
available at https://www.regulations.gov, as referenced above.

Summary of the Biology of the Species

    Bradshaw's lomatium is a perennial herb in the carrot or parsley 
family (Apiaceae) that is endemic to wet prairie habitats in western 
Oregon's Willamette Valley and adjacent southwestern Washington. These 
seasonally wet habitats may be flooded in the spring, or have soils 
saturated at or near the surface due to factors such as heavy 
precipitation in winter and spring, flooding, and poor drainage. A high 
light environment is important for Bradshaw's lomatium to complete its 
life cycle and reproduce, as reduced sunlight is associated with lower 
flower and seed production (Alverson 1993, unpublished data). This 
species is often associated with tufted hairgrass (Deschampsia 
cespitosa), and frequently occurs on and around the small mounds 
created by senescent tufted hairgrass plants. In wetter areas, 
Bradshaw's lomatium occurs on the edges of tufted hairgrass or sedges 
in patches of bare or open soil. In drier areas, it is found in low 
areas, such as small depressions, trails, or seasonal channels, with 
open, exposed soils. Self-fertilization is rare in Bradshaw's lomatium 
(Kaye and Kirkland 1994, p. 8), indicating that pollinator-mediated 
outcrossing is required for reproduction. Over 30 species of solitary 
bees, flies, wasps, and beetles have been observed visiting the flowers 
(Kaye 1992, p. 3; Kaye and Kirkland 1994, p. 9; Jackson 1996, pp. 72-
76). Bradshaw's lomatium does not reproduce asexually and depends 
exclusively on seeds for reproduction (Kaye 1992, p. 2), but does not 
maintain a persistent seed bank in the soil. Although some fruit 
survives in the soil for 1 year, the seeds are not viable (Kaye et al. 
2001, p. 1376). Further information on the basic biology and ecology of 
Bradshaw's lomatium is summarized in the species status report (Service 
2018, entire).

Previous Federal Actions

    Section 12 of the Act directed the Secretary of the Smithsonian 
Institution to prepare a report on those plants considered to be 
endangered, threatened, or extinct. This report, designated as House 
Document No. 94-51, was presented to Congress on January 9, 1975. On 
July 1, 1975, the Service published a notice in the Federal Register 
(40 FR 27823) of its acceptance of the report of the Smithsonian 
Institution as a petition within the context of former section 4(c)(2) 
of the Act (petition acceptance is now governed by section 4(b)(3) of 
the Act), and of its intention to review the status of the plant taxa 
named within. On June 16, 1976, the Service published a proposed rule 
in the Federal Register (41 FR 24523) to determine approximately 1,700 
vascular plant species to be endangered species pursuant to section 4 
of the Act. This list of 1,700 plant taxa was assembled on the basis of 
comments and data received by the Smithsonian Institution and the 
Service in response to House Document No. 94-51 and the July 1, 1975, 
Federal Register publication. Bradshaw's lomatium was included in the 
July 1, 1975, notice of review and in the June 16, 1976, proposal.
    The Amendments of 1978 to the Act (Pub L. 95-632, November 10, 
1978) required that all proposals over 2 years old be withdrawn. A 1-
year grace period was established for proposals already over 2 years 
old. On December 10, 1979, the Service published a document in the 
Federal Register (44 FR 70796) withdrawing the still-pending portion of 
the June 16, 1976, proposal, along with four other proposals that had 
expired. The withdrawal of the proposal to list Bradshaw's lomatium was 
not based on biological considerations, but instead

[[Page 65069]]

was the result of the administrative requirements of the Act prior to 
the 1982 Amendments.
    An updated notice of review, published on December 15, 1980 (45 FR 
82480), listed Bradshaw's lomatium in Category 1, which comprised taxa 
for which sufficient information was available to support the proposal 
of listing as endangered or threatened. On February 15, 1983, the 
Service published notice (48 FR 6752) of its finding that the 
petitioned listing of Bradshaw's lomatium may be warranted, in 
accordance with section 4(b)(3)(A) of the Act, as amended in 1982. On 
October 13, 1983, October 12, 1984, and again on October 11, 1985, the 
petition finding was made that listing of this taxon was warranted, but 
precluded by other pending listing actions, in accordance with section 
4(b)(3)(B)(iii) of the Act (see 51 FR 42117; November 21, 1986). Such a 
finding requires that the petition be treated as a petition that is 
resubmitted, pursuant to section 4(b)(3)(C)(i) of the Act. Therefore, a 
new finding was made; the Service found that the petitioned action was 
warranted, and on November 21, 1986, published a proposal to list the 
species as endangered (51 FR 42116). Bradshaw's lomatium was added to 
the Federal List of Endangered and Threatened Plants (50 CFR 17.12) as 
an endangered species with the publication of a final rule in the 
Federal Register on September 30, 1988 (53 FR 38448)
    A recovery plan for Bradshaw's lomatium (Service 1993, entire) was 
first made available to the public on April 8, 1993 (58 FR 18139, pp. 
18225-18226). Subsequently, a new recovery plan was developed for 
Bradshaw's lomatium in conjunction with several other plant and animal 
species found in prairie ecosystems of western Oregon and southwestern 
Washington. The Recovery Plan for the Prairie Species of Western Oregon 
and Southwest Washington, hereafter referred to as ``the recovery 
plan,'' constitutes the revised recovery plan for Bradshaw's lomatium, 
and was made available to the public on June 29, 2010 (75 FR 37460).
    On July 6, 2005, we published a notice (70 FR 38972) announcing 
that we were conducting a 5-year review of the status of Bradshaw's 
lomatium under section 4(c)(2)(A) of the Act. The 5-year review, 
completed on September 24, 2009 (Service 2009, entire), resulted in a 
recommendation that Bradshaw's lomatium remain listed as an endangered 
species.
    On February 13, 2015, we published a notice (80 FR 8100) announcing 
that we were conducting a new 5-year review of the status of Bradshaw's 
lomatium, and requested that the public provide us any new information 
concerning this species. We developed the species status report for the 
purposes of conducting this 5-year review. This most recent assessment 
of the status of the species led us to recommend that Bradshaw's 
lomatium be removed from the List, because the species is considered to 
be recovered. Because it is our conclusion that Bradshaw's lomatium 
does not now meet the definition of either an endangered or a 
threatened species, as summarized here, we are proposing to remove 
Bradshaw's lomatium from the Federal List of Endangered and Threatened 
Plants (50 CFR 17.12).

Recovery Planning and Recovery Criteria

    Section 4(f) of the Act directs us to develop and implement 
recovery plans for the conservation and survival of endangered and 
threatened species unless we determine that such a plan will not 
promote the conservation of the species. Under section 4(f)(1)(B)(ii), 
recovery plans must, to the maximum extent practicable, include 
objective, measurable criteria which, when met, would result in a 
determination, in accordance with the provisions of section 4 of the 
Act, that the species be removed from the List. However, revisions to 
the List (adding, removing, or reclassifying a species) must reflect 
determinations made in accordance with sections 4(a)(1) and 4(b) of the 
Act. Section 4(a)(1) requires that the Secretary determine whether a 
species is endangered or threatened (or not) because of one or more of 
five threat factors. Section 4(b) of the Act requires that the 
determination be made ``solely on the basis of the best scientific and 
commercial data available.''
    While recovery plans provide important guidance to the Service, 
States, and other partners on methods of minimizing threats to listed 
species and measurable objectives against which to measure progress 
towards recovery, they are not regulatory documents and cannot 
substitute for the determinations and promulgation of regulations 
required under section 4(a)(1) of the Act. A decision to revise the 
status of a species or remove a species from the Federal List of 
Endangered and Threatened Plants (50 CFR 17.12) is ultimately based on 
an analysis of the best scientific and commercial data then available 
to determine whether a species is no longer an endangered species or a 
threatened species, regardless of whether that information differs from 
the recovery plan.
    Recovery plans may be revised to address continuing or new threats 
to the species as new substantive information becomes available. The 
recovery plan recommends site-specific management actions that will 
help recover the species, identifies measurable criteria that set a 
trigger for eventual review of the species' listing status (e.g., under 
a 5-year review conducted by the Service), and methods for monitoring 
recovery progress. Recovery plans are intended to establish goals for 
long-term conservation of listed species and define criteria that are 
designed to indicate when the threats facing a species have been 
removed or reduced to such an extent that the species may no longer 
need the protections of the Act.
    There are many paths to accomplishing recovery of a species, and 
recovery may be achieved without all criteria being fully met. For 
example, one or more criteria may be exceeded while other criteria may 
not yet be met. In that instance, we may determine that the threats are 
minimized sufficiently to delist. In other cases, recovery 
opportunities may be discovered that were not known when the recovery 
plan was finalized. These opportunities may be used instead of methods 
identified in the recovery plan. Likewise, information on the species 
may be learned that was not known at the time the recovery plan was 
finalized. The new information may change the extent that criteria need 
to be met for recognizing recovery of the species. Recovery of a 
species is a dynamic process requiring adaptive management that may, or 
may not, fully follow the guidance provided in a recovery plan.
    In 2010, we finalized the revised recovery plan for Bradshaw's 
lomatium (Service 2010). The recovery plan states that Bradshaw's 
lomatium could be considered for downlisting to threatened status when 
there are 12 populations and 60,000 plants distributed in such a way as 
to reflect the species' historical geographic distribution, when the 
number of individuals in the populations have been stable or increasing 
over a period of 10 years, when sites are managed to meet established 
habitat quality guidelines, when a substantial portion of the species' 
habitat is protected for conservation, and when populations are managed 
to ensure maintenance of habitat and to control threats. To achieve 
desired habitat quality, the recovery plan provides guidelines for a 
variety of prairie habitat metrics. These metrics include:
    (1) Sites with populations of target species should have 50 percent 
or more relative cover of native vegetation;

[[Page 65070]]

    (2) Woody vegetation should make up no more than 15 percent of the 
absolute vegetative cover, and woody species of concern should make up 
no more than 5 percent;
    (3) Native prairie species richness should exceed 10 species, with 
at least 7 forbs and 1 bunchgrass; and
    (4) No single nonnative should have more than 50 percent cover, and 
nonnative species of particular concern should have no greater than 5 
percent cover.
    The recovery plan states that Bradshaw's lomatium could be 
considered for delisting when there are 20 populations and 100,000 
plants properly distributed, in addition to the criteria described 
above. To reflect the historical distribution of Bradshaw's lomatium, 
the species' range was divided into eight recovery zones (called 
Southwest Washington, Portland, Salem West, Salem East, Corvallis West, 
Corvallis East, Eugene West, and Eugene East), and targets for number 
of populations and number of plants for each zone were established 
based on historical presence (Service 2010, pp. IV-1-IV-6, IV-31-IV-
34).
    Two of the recovery zones (Portland and Salem West) are within the 
range of Bradshaw's lomatium, but do not have population targets for 
the species based on a lack of historical occurrence data. These 
recovery zones were nonetheless retained because if any populations of 
Bradshaw's lomatium were to be discovered or introduced within these 
zones, they could be considered as contributing to the recovery 
criteria for the species (under the category ``additional 
populations'').
    The expression of recovery criteria in terms of population 
abundance, numbers of populations, and distribution across recovery 
zones reflects a foundational principle of conservation biology: That 
there is a positive relationship between the relative viability of a 
species over time and the resiliency, redundancy, and representation of 
its constituent populations (Shaffer and Stein 2000, pp. 307-310; Wolf 
et al. 2015, entire). To look at it another way, extinction risk is 
generally reduced as a function of increased population abundance 
(resiliency), numbers of populations (redundancy), and distribution or 
geographic or genetic diversity (representation). The recovery criteria 
laid out in the recovery plan for Bradshaw's lomatium were, therefore, 
informative for our review of the status of the species, as that 
analysis leans upon these measures of viability to assess the current 
and future status of the species (Service 2018, pp. 1-2).
    The downlisting criteria for number and distribution of populations 
and numbers of plants were intended to help identify the point at which 
imminent threats to the plant had been ameliorated so that the 
populations were no longer in immediate risk of extirpation; the 
delisting criteria for number and distribution of populations and 
numbers of plants were intended to identify the point at which the 
species was unlikely to become in danger of extinction. The estimated 
abundance of individuals in all populations has increased over time, 
from approximately 25,000 to 30,000 individuals in 11 populations at 
listing in 1988, to an estimated 11,277,614 individuals in at least 24 
known populations at present (Service 2018, p. 39, updated based on 
Wilderman 2018, entire). These 24 populations occur on 71 distinct 
sites that are owned by a mix of Federal, State, and local governments; 
nongovernmental organizations (NGOs); and private citizens. Multiple 
sites are considered to be part of the same population when those sites 
are within a defined pollinator flight distance of 3 kilometers (km) (2 
miles (mi)) of each other. The current population estimate is the 
combined count data from all sites; for some sites the plant count was 
the result of a full census (54 sites), while for others it was derived 
by visual estimate or calculated from count subsamples that were then 
extrapolated over the total area of the site (17 sites). The increase 
in known populations and number of plants over time is due to a 
combination of population augmentation and introductions, improved 
habitat management, and increased survey effort across the range of the 
species. Bradshaw's lomatium has been the focus of concentrated 
recovery efforts since it was listed in 1988. We now believe there are 
likely more than the recent grand total count of an estimated 
11,277,614 individuals across the range of Bradshaw's lomatium because 
not all areas of suitable habitat within the range of the species have 
been surveyed, and recent visits to previously unsurveyed areas have 
resulted in the identification of formerly unknown populations (e.g., 
Service 2018, p. 10).
    In our species status report, we evaluated and ranked the 
resiliency of each population of Bradshaw's lomatium using the 
following criteria: (1) Population size, (2) current habitat 
conditions, (3) protection of the site from development, and (4) site 
management to restore and maintain appropriate habitat condition. Using 
these criteria, each population was given a rank of high, moderate, or 
low condition (Service 2018, pp. 26-30). The resiliency score for each 
population incorporates the degree to which the primary threats to the 
species have been addressed at each site as well as recovery criteria 
(population size and habitat quality), site protection (addressing 
habitat loss), and site management (addressing woody encroachment and 
invasive species). For details on evaluation and ranking of population 
condition, see the species status report (Service 2018, pp. 26-43).
    The table below summarizes our current knowledge of the abundance 
and distribution of Bradshaw's lomatium relative to the downlisting and 
delisting criteria presented in the recovery plan for the species (from 
Service 2018, p. 39, updated based on Wilderman 2018, entire). Because 
the table below summarizes only the abundance and distribution data for 
the species, the information in the table must be considered in 
conjunction with the five-factor analysis of threats to arrive at the 
status determination for Bradshaw's lomatium.

[[Page 65071]]

    Based on the most recent count, the grand total number of known 
plants is 11,277,614 (this total includes plants from populations with 
fewer than 200 individuals, which we did not count as contributing 
toward recovery). Of this total, an estimated 10,790,658 occur in a 
single population in southwestern Washington. The other approximately 
486,956 plants are within 23 populations in Oregon. Considering only 
the populations in moderate or high condition, and with more than 200 
plants (i.e., those we are counting toward recovery and presented in 
the table above), we estimate there are 485,595 plants within the 23 
populations in Oregon. These populations are distributed from southeast 
of Salem, Oregon south to Creswell, Oregon, both east and west of the 
Willamette River. The greatest density of populations occurs in the 
southern portion of the Willamette Valley near Eugene, Oregon.
    Therefore, the most recent counts of Bradshaw's lomatium identify 
nearly 500,000 individuals in 23 known populations distributed across 
the historical range of the species in Oregon, and distributed among 69 
known sites under various types of land ownership. We considered the 
abundance and distribution of Bradshaw's lomatium without the roughly 
10.8 million individuals concentrated in a single population (made up 
of 2 sites) in southwestern Washington to ensure our evaluation 
considered the abundance and distribution of the species across its 
entire range and to ensure our evaluation was not unduly influenced by 
the single large population in southwestern Washington. Of the 71 known 
sites, 51 are in public ownership, are within a public right-of-way, or 
are owned by a conservation-oriented NGO. Of the 20 remaining sites, 9 
are under conservation easement or are enrolled in the Service's 
Partners for Fish and Wildlife Program (Service 2018, pp. 30-35, 36, 
38, Appendix A). The remaining 11 sites are on private

[[Page 65072]]

lands and are not currently under any formal protection agreements.
    The figure below shows the results of this assessment across the 
range of the species. Of the 24 known populations, 4 are in low 
condition, 9 are in moderate condition, 10 are in high condition, and 1 
is in unknown condition due to the lack of data (Service 2018, pp. 36-
39). Populations occur in all recovery zones that have population 
goals. As noted above, the Portland and Salem West Recovery Zones 
contain no known current populations, were not assigned specific 
targets by the Recovery Team, and have no documented historical 
occurrences of the species within them.

    Based on this information, we conclude Bradshaw's lomatium is much 
more numerous than at the time of listing and is distributed throughout 
its known historical range. Across the 23 populations in Oregon, 
greater than 99 percent of known Bradshaw's lomatium plants are found 
on sites receiving some degree of protection from development

[[Page 65074]]

such as public lands, conservancy lands, or private lands with 
conservation easements (Service 2018, Appendix A). The single largest 
population of the species occurs in southwestern Washington, and is 
composed of individuals from two sites. The vast majority of plants in 
the southwestern Washington population occur on private property that 
is not under some type of protection, but the site is consistently 
managed in a manner conducive to supporting Bradshaw's lomatium. The 
other portion of the population in southwestern Washington contains 
approximately 658 plants, and this site is owned by the Washington 
Department of Natural Resources (WDNR). The WDNR has been actively 
protecting, managing, and augmenting this smaller portion of the 
southwestern Washington population, and they are currently working to 
further expand protection at this site. Furthermore, WDNR is working to 
conserve the sizeable Bradshaw's lomatium site that is on private land.
    Due to ongoing threats from woody encroachment and the spread of 
nonnative invasive plants, sites containing Bradshaw's lomatium require 
regular management to maintain the open prairie conditions that support 
robust populations. Management activities may include, but are not 
limited to, herbicide application, mowing, and prescribed fire. 
Although guarantee of management into perpetuity exceeds the 
requirements of the Act in evaluating whether a species meets the 
statutory definition of endangered or threatened, it is necessary to 
evaluate whether current and expected future management is sufficient 
to maintain resilient populations of Bradshaw's lomatium into the 
foreseeable future. Across the range of Bradshaw's lomatium, 53 of 71 
sites (75 percent) receive some form of management as described above, 
accounting for greater than 99 percent of known Bradshaw's lomatium 
plants. Of the sites with some form of management, 41 sites (58 percent 
of total sites) have a management plan with goals for the conservation 
of Bradshaw's lomatium, or with goals for maintenance of the wet 
prairie habitat upon which this species depends. Sites with management 
plans include those owned by the U.S. Army Corps of Engineers, Bureau 
of Land Management, U.S. Fish and Wildlife Service, The Nature 
Conservancy, and privately owned sites covered by the Natural Resources 
Conservation Service's Wetland Reserve Program (Service 2018, pp. 30-
35, Appendix A).
    These and other data that we analyzed indicate that most threats 
identified at listing and in the recovery plan are reduced in areas 
occupied by Bradshaw's lomatium. The status of the species has improved 
primarily due to: (1) Discovery of previously unknown populations; (2) 
reestablishment and augmentation of populations over the 30 years since 
the species was listed; (3) improvement in habitat management; and (4) 
an increase in protection from development.

Summary of Factors Affecting Bradshaw's Lomatium

    Section 4 of the Act and its implementing regulations (50 CFR part 
424) set forth the procedures for listing species, reclassifying 
species, or removing species from listed status. The term ``species'' 
includes ``any subspecies of fish or wildlife or plants, and any 
distinct population segment [DPS] of any species of vertebrate fish or 
wildlife which interbreeds when mature'' (16 U.S.C. 1532(16)). As 
previously stated, a species may be determined to be an endangered 
species or threatened species because of any one or a combination of 
the five factors described in section 4(a)(1) of the Act. We may 
consider listing a species due to one or more of the following: (A) The 
present or threatened destruction, modification, or curtailment of its 
habitat or range; (B) overutilization for commercial, recreational, 
scientific, or educational purposes; (C) disease or predation; (D) the 
inadequacy of existing regulatory mechanisms; or (E) other natural or 
manmade factors affecting its continued existence. We must consider 
these same five factors in delisting (removal from the Federal Lists of 
Endangered and Threatened Wildlife and Plants) or downlisting 
(reclassification from endangered to threatened) a species.
    For species that are already listed as endangered or threatened, 
this analysis of threats is an evaluation of both the threats currently 
facing the species and the threats that are reasonably likely to affect 
the species in the foreseeable future following the delisting or 
downlisting and the removal of the Act's protections. A recovered 
species is one that no longer meets the Act's definition of endangered 
or threatened. A species is ``endangered'' for purposes of the Act if 
it is in danger of extinction throughout all or a ``significant portion 
of its range'' and is ``threatened'' if it is likely to become an 
endangered species within the foreseeable future throughout all or a 
``significant portion of its range.'' The word ``range'' in the 
``significant portion of its range'' phrase refers to the range in 
which the species currently exists. For the purposes of this analysis, 
we first evaluate the status of Bradshaw's lomatium throughout all of 
its range, then consider whether this plant is in danger of extinction 
or likely to become so in any significant portion of its range within 
the foreseeable future.
    The Act does not define the term ``foreseeable future.'' Our 
implementing regulations at 50 CFR 424.11(d) set forth a framework 
within which we evaluate 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. We consider 25 
to 50 years to be a reasonable period of time within which reliable 
predictions can be made for potential stressors and responses for 
Bradshaw's lomatium. This period of time is sufficient to observe 
population trends for the species and captures the terms of many of the 
management plans that are in effect at Bradshaw's lomatium sites; it 
also provides a reasonable timeframe for the assessment of the effects 
of climate change. Although information exists regarding potential 
impacts from climate change beyond a 50-year timeframe, the projections 
depend on an increasing number of assumptions, and thus become more 
uncertain with increasingly long timeframes. We, therefore, use a 
maximum timeframe of 50 years to provide the best balance of scope of 
impacts considered versus the certainty of those impacts being 
realized.
    In considering what factors might constitute threats, we must look 
beyond the exposure of the species to a particular factor to evaluate 
whether the species may respond to the factor in a way that causes 
actual impacts to the species. If there is exposure to a factor and the 
species responds negatively, the factor may be a threat, and during the 
status review, we attempt to determine the significance of a threat. 
The threat is significant if it drives or contributes to the risk of 
extinction of the species, such that the species warrants listing as 
endangered or threatened as those terms are defined by the Act. 
However, the identification of factors that could impact a species 
negatively may not be sufficient to compel a finding that the species 
warrants listing. The information must include evidence sufficient to 
suggest that the potential threat is likely to materialize and that it 
has the capacity (i.e., it should be of sufficient magnitude and 
extent) to affect the species' status such that it

[[Page 65075]]

meets the definition of endangered or threatened under the Act.
    At the time of listing, the primary threats to Bradshaw's lomatium 
were habitat loss due to land use conversion for agriculture or 
urbanization and the invasion of prairie vegetation by various woody 
plant species (Factor A) (53 FR 38449-38450; September 30, 1988). The 
listing rule did not find that overutilization for commercial, 
recreational, scientific, or educational purposes (Factor B) posed a 
threat to Bradshaw's lomatium. The listing rule did note that several 
parasitic organisms (a fungus, spittle bug, and two aphids) could 
potentially have negative effects on smaller, stressed populations of 
the plant (but not the species as a whole; Factor C) and questioned 
whether inbreeding depression might pose a threat to the species since 
the populations known at the time appeared to be small and isolated 
from one another (Factor E). The rule noted that further study was 
required to determine the significance of these putative threat 
factors. Finally, the listing rule noted that State and Federal 
regulations existing at the time did not adequately protect the plant 
from habitat loss or other potential threats (Factor D) (53 FR 38450; 
September 30, 1988). By the time the recovery plan was developed in 
1993, these same threats were still considered relevant (Service 1993, 
p. 12). There are three potential threats that were not known or 
considered at the time of listing: (1) Competition from nonnative, 
invasive plant species (Factor A); (2) potential impacts resulting from 
the effects of climate change (Factor E); and (3) predation by voles 
(Microtus spp.) (Factor C), which has been observed within Bradshaw's 
lomatium sites. Subsequently, we have conducted a 5-year status review 
based on the species status report for Bradshaw's lomatium that 
includes an analysis of all factors known to affect the viability of 
the species (Service 2018, entire).
    As discussed in our 2018 species status report, the threat of 
habitat loss from land conversion for agriculture and urbanization 
(Factor A) has decreased since the time of listing due to land 
protection efforts. Although a few privately owned sites are still at 
risk, land use conversion is no longer considered a significant threat 
to the viability of Bradshaw's lomatium due to the number of sites now 
receiving some degree of protection from development (Service 2018, pp. 
36-39, Appendix A). As described above, in Oregon, which supports 23 of 
the 24 known populations of the species, greater than 99 percent of 
known Bradshaw's lomatium plants occur on sites protected through 
public or NGO ownership, through designation as a right-of-way, or by 
conservation easements on private lands. In Washington, one of two 
sites that support Bradshaw's lomatium is owned by WDNR, and the State 
is actively working toward the conservation of the very large adjacent 
site that supports the majority of known individuals of the species. As 
the threat posed to Bradshaw's lomatium from habitat loss is no longer 
considered significant, we additionally no longer consider State or 
Federal protections to be inadequate to address this threat (Factor D).
    The present threat to Bradshaw's lomatium from modification of 
habitat due to invasion of prairies by nonnative, invasive plants and 
by woody species (Factor A) has been reduced in many populations due to 
active habitat management using herbicides, mowing, and prescribed 
fire, but ongoing habitat management is required to maintain these 
improvements. As noted above, across the range of Bradshaw's lomatium, 
75 percent of the known sites receive active management that benefits 
the species, and 58 percent of total sites have a management plan in 
place with goals for the conservation of Bradshaw's lomatium, or for 
maintenance of the wet prairie habitat upon which it depends (Service 
2018, pp. 36-39, Appendix A). Based on the high proportion of sites 
protected or managed, the history of positive management observed to 
date, and ongoing efforts to further restore and protect wet prairie 
habitats, we have confidence that management of Bradshaw's lomatium 
sites will continue to provide adequate protection to the species in 
the long term. We found no evidence that negative impacts due to 
parasitic organisms (Factor C) constitute a threat to the viability of 
the Bradshaw's lomatium. Predation by voles (Factor C) appears to vary 
year to year, and can substantially reduce aboveground biomass and 
reproduction in years when vole abundance is high. However, the effect 
on populations is believed to be minimal over time as long as there is 
sufficient time for Bradshaw's lomatium to regenerate taproot reserves 
between vole outbreaks (Drew 2000, pp. 54-55), and no consistent long-
term declines attributable to vole predation have been reported 
(Service 2018, p. 20).
    Concerns over the possibility of inbreeding depression (Factor E) 
expressed at the time of listing are now reduced due to a subsequent 
study indicating that overall genetic diversity in Bradshaw's lomatium 
is relatively high for a rare species (Gitzendanner and Soltis 2001, 
pp. 352-353), and is greater than that found in other rare Lomatium 
species (Gitzendanner and Soltis 2000, p. 787), though the most 
disjunct population in southwestern Washington showed relatively lower 
genetic diversity than less geographically isolated populations 
(Gitzendanner and Soltis 2001, p. 353). The threat of inbreeding 
depression is further considered reduced since we now understand 
Bradshaw's lomatium to be primarily an outcrossing species (which 
promotes increased genetic diversity), rather than an obligate self-
pollinating species as was believed at the time of listing (Service 
2018, pp. 7, 20).
    The potential threat posed to Bradshaw's lomatium from the effects 
of climate change (Factor E) is difficult to predict. The primary 
threat to the species from the effects of climate change is likely 
reduced moisture availability due to warmer temperatures and 
alterations to precipitation patterns resulting in increased 
evapotranspiration. The vulnerability of Bradshaw's lomatium to the 
effects of climate change, assessed over a range of potential future 
emissions scenarios, has been ranked as anywhere from low to moderate 
(Steel et al. 2011, pp. 25, 89) to highly vulnerable (Kaye et al. 2013, 
p. 20). Possible effects of climate change on Bradshaw's lomatium 
include a shift toward life cycle completion earlier in the growing 
season in response to warmer temperatures and earlier drying, and 
reduced population sizes due to some portions of habitat drying too 
much to support Bradshaw's lomatium populations. We assessed the 
potential impacts of climate change on Bradshaw's lomatium projected 
out over a period up to 50 years in the future. Published assessments 
provide only qualitative appraisals of the potential response of 
Bradshaw's lomatium to the effects of climate change; therefore, to be 
conservative in our analysis, we evaluated a ``worst case'' future 
scenario in which all populations would be reduced in size by 50 
percent. Even in the face of such a severe population reduction, the 
species is anticipated to remain viable as indicated by appreciable 
levels of resiliency, redundancy, and representation. We estimated that 
populations currently in low condition or with very low abundance may 
be extirpated due to the combined effects of climate change impacts and 
stochastic events; this translated to an estimated loss of up to five 
small populations, with other populations reduced in size. However, 
even with a presumed 50 percent

[[Page 65076]]

reduction in abundance, at least 14 to 16 populations of Bradshaw's 
lomatium in moderate or high condition are expected to persist on the 
landscape with ongoing management. We do not anticipate any significant 
effect on representation, that is, the ability of the species to adapt 
to changing environmental conditions over time (Service 2018, pp. 42-
46).

Cumulative Impacts

    When multiple stressors co-occur, one may exacerbate the effects of 
the other, leading to effects not accounted for when each stressor is 
analyzed individually. The full impact of these synergistic effects may 
be observed within a short period of time, or may take many years 
before they are noticeable. For example, high levels of predation on 
Bradshaw's lomatium during vole outbreaks can cause large temporary 
population declines, but are not generally considered a significant 
threat to long-term viability; populations that are relatively large 
and well distributed should be able to withstand such naturally 
occurring events. However, the relative impact of predation by voles 
may be intensified when outbreaks occur in conjunction with other 
factors that may lessen the resiliency of Bradshaw's lomatium 
populations, such as prolonged woody species encroachment; extensive 
nonnative, invasive plant infestations; or possible hydrological 
alterations resulting from the effects of climate change.
    Although the types, magnitude, or extent of potential cumulative 
impacts are difficult to predict, we are not aware of any combination 
of factors that are likely to co-occur with significant negative 
consequences for the species. We anticipate that any negative 
consequence of co-occurring threats will be successfully addressed 
through the same active management actions that have contributed to the 
ongoing recovery of Bradshaw's lomatium and that are expected to 
continue into the future. The best scientific and commercial data 
available indicate that Bradshaw's lomatium is composed of multiple 
populations, primarily in moderate to high condition, which are 
sufficiently resilient, well distributed, protected, and managed such 
that they will be robust to any potential cumulative effects to which 
they may be exposed.
    Overall, we conclude that under current conditions, most 
populations of Bradshaw's lomatium are resilient, because they have 
abundant numbers of individuals. There are redundant populations of 
Bradshaw's lomatium, meaning that multiple populations occur in most 
recovery zones, indicating that the species has the ability to minimize 
potential loss from catastrophic events. The concern at the time of 
listing about a possible genetic bottleneck has been alleviated by 
genetic studies demonstrating that Bradshaw's lomatium has relatively 
high genetic diversity for a rare species. Also, with populations 
distributed across the known historical range of the species (Service 
2018, p. 40), Bradshaw's lomatium has likely retained much of its 
adaptive capacity (i.e., representation). We also considered the 
potential future conditions of Bradshaw's lomatium, taking into account 
the current condition and additional stressors not considered at the 
time of recovery plan development (e.g., the effects of climate 
change). Projecting 25 to 50 years into the future, under a 
conservative estimate that conditions could potentially worsen such 
that all existing populations are reduced by half, the species would 
retain its resiliency and redundancy. With an estimated 14 to 16 
populations in moderate or high condition expected to persist on the 
landscape with ongoing management; representation was not anticipated 
to be affected (Service 2018, p. 44). As noted earlier, the degree to 
which threats to the species have been successfully addressed is 
incorporated into the evaluation of population resiliency at each site 
(i.e., site protection and management actions were considered in the 
scoring of each population's current condition; Service 2018, p. 28). 
The continuation of these conservation measures was an assumption of 
our projection.
    See the species status report (Service 2018, entire) for a more 
detailed discussion of our evaluation of the biological status of the 
Bradshaw's lomatium and the influences that may affect its continued 
existence. Our conclusions are based upon the best available scientific 
and commercial data and the expert opinions of the species status 
assessment team members.

Determination of Bradshaw's Lomatium 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 ``endangered species'' or 
``threatened species.'' The Act defines an ``endangered species'' as a 
species that is ``in danger of extinction throughout all or a 
significant portion of its range,'' and a ``threatened species'' as a 
species that is ``likely to become an endangered species within the 
foreseeable future throughout all or a significant portion of its 
range.'' The Act requires that we determine whether a species meets the 
definition of ``endangered species'' or ``threatened species'' because 
of any of the following factors: (A) The present or threatened 
destruction, modification, or curtailment of its habitat or range; (B) 
overutilization for commercial, recreational, scientific, or 
educational purposes; (C) disease or predation; (D) the inadequacy of 
existing regulatory mechanisms; or (E) other natural or manmade factors 
affecting its continued existence.

Status Throughout All of Its Range

    After evaluating threats to the species under the section 4(a)(1) 
factors, we found that the known range of Bradshaw's lomatium was 
considered dramatically reduced when we listed it as an endangered 
species in 1988, and we estimated that there were 11 small populations 
that included a total of roughly 25,000 to 30,000 individuals. In 
addition, the species faced threats from habitat loss due to land 
conversion for agriculture and urbanization, as well as natural 
succession to woody species dominance due to loss of historical 
disturbance regimes. As such, it was perceived to be upon the brink of 
extinction. Bradshaw's lomatium has been the subject of intensive 
recovery efforts since it was listed under the Act 30 years ago, and 
the discovery of new, previously unknown populations; success in 
augmentation and habitat restoration and management efforts; and the 
protection of Bradshaw's lomatium populations and habitats on public 
lands and on private lands through conservation easements and 
management agreements with NGOs and other parties have led to a 
significant reduction in threats and improvement in the status of the 
species since that time.
    Recovery goals for delisting Bradshaw's lomatium were set at a 
minimum of 20 populations with a total of 100,000 individual plants 
distributed across its historical range. Under current conditions, 
there are 24 known populations of Bradshaw's lomatium distributed 
throughout the species' historical range; if we consider only those 
populations in high or moderate condition and containing at least 200 
individuals as contributing to recovery, there are 17 such populations 
throughout the range of the species (see table above). Considering only 
those 17 populations in high or moderate condition and with greater 
than 200 plants, the most recent counts demonstrate there are an 
estimated

[[Page 65077]]

486,253 individuals known distributed throughout the historical range 
of the species (our evaluation does not include the southwestern 
Washington population to ensure our evaluation considered the abundance 
and distribution of the species across its entire range and that it was 
not unduly influenced by this single large population). Our analysis of 
current population condition on the basis of plant abundance, habitat 
quality, management, and protection from development resulted in 
rankings of 10 populations in high condition overall, 9 populations in 
moderate condition, and 4 populations in low condition. Therefore, we 
are significantly less concerned about small population sizes or 
limited distribution of the species than we were at the time of 
listing. The increase in known populations is due in large part to 
increased survey efforts and incidental discovery of more occupied 
habitat, leaving open the potential of finding even more populations of 
Bradshaw's lomatium in the future. Acquisition by conservation NGOs, or 
enrollment into conservation easement programs, of sites containing 
Bradshaw's lomatium populations has substantially reduced the risk of 
habitat and population losses due to land use conversion (Factor A). In 
addition, population augmentation or introduction, combined with 
ongoing active management of woody encroachment and of nonnative, 
invasive plant infestations, has ameliorated the threat posed by these 
processes (Factor A) and increased the resilience of many Bradshaw's 
lomatium populations on protected sites. Other potential threats 
identified at the time of listing have either never materialized 
(parasitism by other organisms (Factor C) or negative effects of 
inbreeding depression (Factor E)) or have been addressed through other 
means (i.e., habitat protections and management, addressing Factor D).
    Since listing, we have become aware of the potential for the 
effects of climate change (Factor E) to affect organisms and 
ecosystems, including potentially Bradshaw's lomatium. We considered 
the potential consequences of climate change and evaluated a future 
scenario with up to a 50 percent reduction in the size of all known 
populations across the range of the species. Even in the face of such a 
severe population reduction, the species retained appreciable levels of 
resiliency, redundancy, and representation such that we did not 
consider the effects of climate change to pose a significant threat 
(Service 2018, pp. 42-46). To be conservative, our analysis of future 
conditions did not consider that ongoing efforts to improve population 
sizes and habitat quality have the potential to further increase the 
number of resilient populations of Bradshaw's lomatium. Many stressors 
to the species are being addressed through habitat management and 
population augmentation, but ongoing management is necessary to 
maintain resilient populations throughout the species' range.
    In sum, significant impacts at the time of listing such as habitat 
loss due to land use conversion and woody encroachment that could have 
resulted in the extirpation of all or parts of populations have been 
either eliminated or reduced since listing. An assessment of likely 
future conditions, including the status of known stressors, management 
trends, and possible impacts of climate change, finds that although 
populations may decline in abundance, at least 14 to 16 populations 
across the range of the species are expected to maintain high or 
moderate resiliency over a timeframe of 25 to 50 years into the future 
(Service 2018, pp. 42-46). We, therefore, conclude that the previously 
recognized impacts to Bradshaw's lomatium from present or threatened 
destruction, modification, or curtailment of its habitat or range 
(specifically, habitat development for agriculture or urbanization and 
invasion of prairie vegetation by various woody plant species) (Factor 
A); disease or predation (specifically, parasitism by insects and 
predation by voles) (Factor C); the inadequacy of existing regulatory 
mechanisms (Factor D); and other natural or manmade factors affecting 
its continued existence (specifically, genetic isolation, inbreeding 
depression, and the effects of climate change) (Factor E) do not rise 
to a level of significance, either individually or in combination, such 
that the species is in danger of extinction now or likely to become so 
within the foreseeable future. Overutilization for commercial, 
recreational, scientific, or educational purposes (Factor B) was not a 
factor in listing and based on the best available information, we 
conclude that it does not constitute a threat to the Bradshaw's 
lomatium now or in the foreseeable future. The Service recognizes that 
woody encroachment and nonnative, invasive plant species are stressors 
with ongoing impacts to Bradshaw's lomatium, but finds that current and 
expected trends in site protection and habitat management are 
sufficient to prevent these stressors from constituting a threat to the 
continued existence of the species. Thus, after assessing the best 
available information, we conclude that Bradshaw's lomatium is not in 
danger of extinction or likely to become so within the foreseeable 
future throughout all of its range.

Status Throughout a Significant Portion of Its Range

    Under the Act and our implementing regulations, a species may 
warrant listing if it is in danger of extinction or likely to become so 
in the foreseeable future throughout all or a significant portion of 
its range (SPR). Where the best available information allows the 
Services to determine a status for the species rangewide, that 
determination should be given conclusive weight because a rangewide 
determination of status more accurately reflects the species' degree of 
imperilment and better promotes the purposes of the Act. Under this 
reading, we should first consider whether the species warrants listing 
``throughout all'' of its range and proceed to conduct a ``significant 
portion of its range'' analysis if, and only if, a species does not 
qualify for listing as either an endangered or a threatened species 
according to the ``throughout all'' language.
    Having determined that Bradshaw's lomatium 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 an SPR. 
The range of a species can theoretically be divided into portions in an 
infinite number of ways, so we first screen the potential portions of 
the species' range to determine if there are any portions that warrant 
further consideration. To do the ``screening'' analysis, we ask whether 
there are portions of the species' range for which there is substantial 
information indicating that: (1) The portion may be significant; and, 
(2) the species may be, in that portion, either in danger of extinction 
or likely to become so in the foreseeable future. For a particular 
portion, if we cannot answer both questions in the affirmative, then 
that portion does not warrant further consideration and the species 
does not warrant listing because of its status in that portion of its 
range. We emphasize that answering both of these questions in the 
affirmative is not a determination that the species is in danger of 
extinction or likely to become so in the foreseeable future throughout 
a significant portion of its range--rather, it is a step in determining 
whether a more-detailed analysis of the issue is required.
    If we answer these questions in the affirmative, we then conduct a 
more

[[Page 65078]]

thorough analysis to determine whether the portion does indeed meet 
both of the SPR prongs: (1) The portion is significant and (2) the 
species is, in that portion, either in danger of extinction or likely 
to become so in the foreseeable future. Confirmation that a portion 
does indeed meet one of these prongs does not create a presumption, 
prejudgment, or other determination as to whether the species is an 
endangered species or threatened species. Rather, we must then 
undertake a more detailed analysis of the other prong to make that 
determination. Only if the portion does indeed meet both SPR prongs 
would the species warrant listing because of its status in a 
significant portion of its range.
    At both stages in this process--the stage of screening potential 
portions to identify any portions that warrant further consideration 
and the stage of undertaking the more detailed analysis of any portions 
that do warrant further consideration--it might be more efficient for 
us to address the ``significance'' question or the ``status'' question 
first. Our selection of which question to address first for a 
particular portion depends on the biology of the species, its range, 
and the threats it faces. 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 second question for 
that portion of the species' range.
    The Service's most-recent definition of ``significant'' has been 
invalidated by the courts (for example, Desert Survivors v. Dep't of 
the Interior, No. 16-cv-01165-JCS (N.D. Cal. Aug. 24, 2018)). 
Therefore, we determined whether the populations in Oregon and 
Washington could be significant under any reasonable definition of 
``significant.'' To do this, we evaluated whether these populations 
taken together may be biologically important in terms of the 
resiliency, redundancy, or representation of the species.
    We identified the population of Bradshaw's lomatium in southwestern 
Washington as a potential portion of the range warranting further 
detailed consideration due to its potential contributions to the 
resiliency, redundancy, and representation of the species. This 
population is the northernmost known population of the species 
(contributing to representation), and is separated from the majority of 
the range by the Columbia River and a large, historically unoccupied 
area in northern Oregon (contributing to redundancy). It is also the 
largest known population of Bradshaw's lomatium (contributing to 
resiliency).
    The southwestern Washington population of Bradshaw's lomatium is 
composed of individuals occurring at two separate sites in close 
proximity to each other. The smaller of the two sites contained an 
estimated 658 Bradshaw's lomatium individuals in 2018 (Wilderman 2018, 
entire), and is owned and managed by the WDNR. The WDNR manages this 
site with an emphasis on habitat management, population augmentation, 
and monitoring to benefit Bradshaw's lomatium. The larger site occurs 
on the rough of a privately owned golf co
