Endangered and Threatened Wildlife and Plants; Endangered Species 
Status for Ghost Orchid

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Proposed rule.

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

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), propose to 
list the ghost orchid (Dendrophylax lindenii), a flowering plant 
species found in the United States in southwestern Florida and in Cuba 
as an endangered species under the Endangered Species Act of 1973, as 
amended (Act). This determination also serves as our 12-month finding 
on a petition to list the ghost orchid. After a review of the best 
scientific and commercial data available, we find that listing the 
species is warranted. Accordingly, we propose to list the ghost orchid 
as an endangered species under the Act. If we finalize this rule as 
proposed, it would add this species to the List of Endangered and 
Threatened Plants and extend the Act's protections to the species. We 
find that designating critical habitat for this species is not prudent.

DATES: We will accept comments received or postmarked on or before 
August 4, 2025. Comments submitted electronically using the Federal 
eRulemaking Portal (see ADDRESSES, below) must be received by 11:59

SUPPLEMENTARY INFORMATION:

Executive Summary

    Why we need to publish a rule. Under the Act (16 U.S.C. 1531 et 
seq.), a species warrants listing if it meets the definition of an 
endangered species (in danger of extinction throughout all or a 
significant portion of its range) or a threatened species (likely to 
become an endangered species within the foreseeable future throughout 
all or a significant portion of its range). If we determine that a 
species warrants listing, we must list the species promptly and 
designate the species' critical habitat to the maximum extent prudent 
and determinable. We have determined that the ghost orchid meets the 
Act's definition of an endangered species; therefore, we are proposing 
to list it as such. Listing a species as an endangered or threatened 
species can be completed only by issuing a rule through the 
Administrative Procedure Act rulemaking process (5 U.S.C. 551 et seq.).
    What this document does. We propose to list the ghost orchid as an 
endangered species under the Act.
    The basis for our action. Under the Act, we may determine that a 
species is an endangered or threatened species because of any of five 
factors: (A) The present or threatened destruction, modification, or 
curtailment of its habitat or range; (B) overutilization for 
commercial, recreational, scientific, or educational purposes; (C) 
disease or predation; (D) the inadequacy of existing regulatory 
mechanisms; or (E) other natural or manmade factors affecting its 
continued existence. We have determined that the ghost orchid meets the 
Act's definition of an endangered species due to threats associated 
with poaching (Factor B), habitat degradation due to hydrological 
changes (Factor A), and the damage to the species and the host trees 
from the increased intensity and frequency of hurricanes and impacts 
from saltwater intrusion (Factor E).
    Section 4(a)(3) of the Act requires that the Secretary of the 
Interior (Secretary), to the maximum extent prudent and determinable, 
concurrently with listing designate critical habitat for the species. 
Section 3(5)(A) of the Act defines critical habitat as (i) the specific 
areas within the geographical area occupied by the species, at the time 
it is listed, on which are found those physical or biological features 
(I) essential to the conservation of the species and (II) which may 
require special management considerations or protections; and (ii) 
specific areas outside the geographical area occupied by the species at 
the time it is listed, upon a determination by the Secretary that such 
areas are essential for the conservation of the species. Section 
4(b)(2) of the Act states that the Secretary must make the designation 
on the basis of the best scientific data available and after taking 
into consideration the economic impact, the impact on national 
security, and any

[[Page 23870]]

other relevant impacts of specifying any particular area as critical 
habitat. Because we have determined that the designation of critical 
habitat will likely increase the degree of threat to the species, we 
find that designation of critical habitat is not prudent for the ghost 
orchid.

Information Requested

    We intend that any final action resulting from this proposed rule 
will be based on the best scientific and commercial data available and 
be as accurate and as effective as possible. Therefore, we request 
comments or information from other governmental agencies, Native 
American Tribes, the scientific community, industry, or any other 
interested parties concerning this proposed rule. We particularly seek 
comments concerning:
    (1) The species' biology, range, and population trends, including:
    (a) Biological or ecological requirements of the species, including 
habitat requirements for pollination and reproduction;
    (b) Genetics and taxonomy;
    (c) Historical and current range, including distribution patterns 
and locations of any additional populations of this species;
    (d) Historical and current population levels, and current and 
projected trends; and
    (e) Past and ongoing conservation measures for the species, its 
habitat, or both.
    (2) Threats and conservation actions affecting the species, 
including:
    (a) Factors that may be affecting the continued existence of the 
species, which may include habitat modification or destruction, 
overutilization, disease, predation, the inadequacy of existing 
regulatory mechanisms, or other natural or manmade factors;
    (b) Biological, commercial trade, or other relevant data concerning 
any threats (or lack thereof) to this species; and
    (c) Existing regulations or conservation actions that may be 
addressing threats to this species.
    (3) Additional information concerning the historical and current 
status of this species.
    (4) Information regarding our determination that designating 
critical habitat for the ghost orchid is not prudent.
    Please include sufficient information with your submission (such as 
scientific journal articles or other publications) to allow us to 
verify any scientific or commercial information you include.
    Please note that submissions merely stating support for, or 
opposition to, the action under consideration without providing 
supporting information, although noted, do not provide substantial 
information necessary to support a determination, as section 4(b)(1)(A) 
of the Act directs that determinations as to whether any species is an 
endangered or a threatened species must be made solely on the basis of 
the best scientific and commercial data available, and section 4(b)(2) 
of the Act directs that the Secretary shall designate critical habitat 
on the basis of the best scientific data available.
    You may submit your comments and materials concerning this proposed 
rule by one of the methods listed in ADDRESSES. We request that you 
send comments only by the methods described in ADDRESSES.
    If you submit information via , your 
entire submission--including any personal identifying information--will 
be posted on the website. If your submission is made via a hardcopy 
that includes personal identifying information, you may request at the 
top of your document that we withhold this information from public 
review. However, we cannot guarantee that we will be able to do so. We 
will post all hardcopy submissions on .
    Comments and materials we receive, as well as supporting 
documentation we used in preparing this proposed rule, will be 
available for public inspection on .
    Our final determination may differ from this proposal because we 
will consider all comments we receive during the comment period as well 
as any information that may become available after this proposal. Based 
on the new information we receive (and, if relevant, any comments on 
that new information), we may conclude that the species is threatened 
instead of endangered, or we may conclude that the species does not 
warrant listing as either an endangered species or a threatened 
species. In our final rule, we will clearly explain our rationale and 
the basis for our final decision, including why we made changes, if 
any, that differ from this proposal.

Public Hearing

    Section 4(b)(5) of the Act provides for a public hearing on this 
proposal, if requested. Requests must be received by the date specified 
in DATES. Such requests must be sent to the address shown in FOR 
FURTHER INFORMATION CONTACT. We will schedule a public hearing on 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. We may hold the public hearing in person or virtually via 
webinar. We will announce any public hearing on our website, in 
addition to the Federal Register. The use of virtual public hearings is 
consistent with our regulations at 50 CFR 424.16(c)(3).

Previous Federal Actions

    On January 24, 2022, we received a petition from The Institute for 
Regional Conservation, the National Parks Conservation Association, and 
the Center for Biological Diversity requesting that the ghost orchid be 
listed under the Act as a threatened species or an endangered species 
and that critical habitat for the species be designated. Section 
4(b)(3)(A) of the Act requires that we make a finding on whether a 
petition to add a species to the Lists of Endangered and Threatened 
Wildlife and Plants, remove a species from the Lists, or change a 
listed species' status (from endangered to threatened or from 
threatened to endangered) presents substantial scientific or commercial 
information indicating that the petitioned action may be warranted. To 
the maximum extent practicable, we are to make this finding within 90 
days of our receipt of the petition and publish the finding promptly in 
the Federal Register. On October 19, 2022, we published in the Federal 
Register (87 FR 63468) a 90-day finding that the petition contained 
substantial information indicating that listing the ghost orchid may be 
warranted and initiated a status review.
    Under section 4(b)(3)(B) of the Act, we are required to make a 
finding within 12 months after receiving any petition that we have 
determined contains substantial scientific or commercial information 
indicating that the petitioned action may be warranted, as to whether 
the petitioned action is warranted, not warranted, or warranted but 
precluded by other pending proposals. We must publish a notification of 
this 12-month finding in the Federal Register. This proposed rule 
constitutes our 12-month finding on the petition.

Peer Review

    A species status assessment (SSA) team prepared an SSA report for 
the ghost orchid. The SSA team was composed of Service biologists, in 
consultation with other species experts. The SSA report represents a 
compilation of the best scientific and commercial data available 
concerning the status of the species, including the

[[Page 23871]]

impacts of past, present, and future factors (both negative and 
beneficial) affecting the species.
    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 in 
listing and recovery actions under the Act (/sites/default/files/documents/peer-review-policy-directors-memo-2016-08-22.pdf), we solicited independent scientific review of the information 
contained in the ghost orchid SSA report. We sent the SSA report to 
five independent peer reviewers and received two responses. The peer 
reviews can be found at  under Docket No. 
FWS-R4-ES-2025-0022. In preparing this proposed rule, we incorporated 
the results of these reviews, as appropriate, into the SSA report, 
which is the foundation for this proposed rule.

Summary of Peer Reviewer Comments

    As discussed in Peer Review above, we received comments from two 
peer reviewers on the draft SSA report. We reviewed all comments we 
received from the peer reviewers for substantive issues and new 
information regarding the contents of the SSA report. The peer 
reviewers generally concurred with our methods and conclusions, and 
provided additional information, clarifications, and suggestions, 
including clarifications in terminology and discussions of life 
history, and other editorial suggestions. New information was provided 
about impacts from recent hurricanes and poaching in both Cuba and 
Florida, as well as saltwater intrusion on ghost orchid habitats in 
Florida. We added this information to the SSA report. Otherwise, no 
substantive changes to our analysis and conclusions within the SSA 
report were deemed necessary, and peer reviewer comments are addressed 
in version 1.1 of the SSA report.

I. Proposed Listing Determination

Background

    A thorough review of the taxonomy, life history, and ecology of the 
ghost orchid is presented in the SSA report (version 1.1; Service 2025, 
pp. 11-15).
    The ghost orchid is a white, showy flowering plant endemic to 
southwestern Florida and western Cuba (figure 1, below).
[GRAPHIC] [TIFF OMITTED] TN05JN25.002

Figure 1. Map Showing the Range of Ghost Orchid in Southwest Florida 
and Western Cuba

    Ghost orchid populations in Florida occur in the western Greater 
Everglades ecosystem in approximately eight isolated locations (on 
mostly protected or managed lands), across an area just over 1,450 
square miles (3,757 square kilometers). In Cuba, fewer than 230 ghost 
orchid plants are known from one area in Guanahacabibes National Park 
in the southwestern part of the country. For the purposes of evaluating 
current resiliency, we identified analysis units for ghost orchids that 
relate to ownership and management areas (see table 1, below) and 
likely represent discrete populations (see Current Condition below for 
more details).
    Ghost orchid plants have also been reported in eastern Cuba 
including the province of Granma (Rio Portillo), Las Tunas, Santiago de 
Cuba, Guantanamo, and Holguin provinces (Zettler et al 2019, p. 140; 
Natureserve 2021, p. 3). None of these populations are believed to be 
extant (M[uacute]jica 2021, entire). In addition, two plants were 
reported from Ci[eacute]naga de Zapata National Park about 200 miles 
(320 kilometers) to the east of Guanahacabibes, but these reports were 
unconfirmed and the plants are presumed to be extirpated (Zettler et 
al. 2019, p. 140).

    The ghost orchid is a leafless plant species that uses its roots to 
photosynthesize and attach itself to a host tree. In Florida, ghost 
orchids are found in wet freshwater environments including dome swamps 
(an isolated, forested, depression wetland occurring within a fire-
maintained community such as mesic flatwoods (an open canopy of tall 
pines and a dense, low ground layer of low shrubs, grasses, and 
forbs)), sloughs (broad channels inundated with slow moving or nearly 
stagnant water, except during extreme droughts), and strand swamps (a 
shallow, forested, usually elongated depression or channel situated in 
a trough within a flat limestone plain, and dominated primarily by bald 
cypress (Taxodium distichum)). Across these habitat types, ghost 
orchids are primarily found on Florida water ash (Fraxinus cubensis) 
(Nesom 2010, entire; Weakley 2023, pp. 818-819) and pond apple (Annona 
glabra) host trees, and to a lesser extent on bald cypress (Owen 2024, 
entire). In Cuba, ghost orchids are found growing on tropical semi-
deciduous hardwood host trees that are rooted in fractured reef 
limestone with little or no standing water (M[uacute]jica et al. 2018, 
p. 573). Ghost orchids in Cuba are typically found growing on 5 
different host tree species, though 18 host tree species have been 
recorded (M[uacute]jica et al. 2018, p. 577).
    In Florida, reproductively mature ghost orchid plants produce 
flowers from May to August, though flowers have occasionally been 
observed outside of these months (Brown 2002, p. 80; Flora of North 
America 2002, p. 621). Plants in Cuba typically flower between October 
and December (M[uacute]jica et al. 2018, p. 575). In the wild, it may 
take 15 years or more for a ghost orchid plant to first produce flowers 
(Houlihan et al. 2019, p. 7). By contrast, in controlled environments 
plants can become reproductive earlier (Davis 2009, pp. 414-415; Hoang 
et al. 2016, p. 390; Houlihan et al. 2019, p. 7). At night, flowers 
produce a sweet, fruity fragrance that attracts two specific 
pollinators, the fig sphinx moth (Pachylia ficus) and pawpaw sphinx 
moth (Dolba hyloeus), that are nocturnally active (Houlihan et al. 
2019, p.4; Danaher et al. 2020, p. 673).

Regulatory and Analytical Framework

Regulatory Framework

    Section 4 of the Act (16 U.S.C. 1533) and the implementing 
regulations in title 50 of the Code of Federal Regulations set forth 
the procedures for determining whether a species is an endangered 
species or a threatened species, issuing protective regulations for 
threatened species, and designating critical habitat for endangered and 
threatened species.
    The Act defines an ``endangered species'' as a species that is in 
danger of extinction throughout all or a significant portion of its 
range and a ``threatened species'' as a species that is likely to 
become an endangered species within the foreseeable future throughout 
all or a significant portion of its range. The Act requires that we 
determine whether any species is an endangered species or a threatened 
species because of any of the following factors:
    (A) The present or threatened destruction, modification, or 
curtailment of its habitat or range;
    (B) Overutilization for commercial, recreational, scientific, or 
educational purposes;
    (C) Disease or predation;
    (D) The inadequacy of existing regulatory mechanisms; or
    (E) Other natural or manmade factors affecting its continued 
existence.
    These factors represent broad categories of natural or human-caused 
actions or conditions that could have an effect on a species' continued 
existence. In evaluating these actions and conditions, we look for 
those that may have a negative effect on individuals of the species, as 
well as other actions or conditions that may ameliorate any negative 
effects or may have positive effects.
    We use the term ``threat'' to refer in general to actions or 
conditions that are known to or are reasonably likely to negatively 
affect individuals of a species. The term ``threat'' includes actions 
or conditions that have a direct impact on individuals (direct 
impacts), as well as those that affect individuals through alteration 
of their habitat or required resources (stressors). The term ``threat'' 
may encompass--either together or separately--the source of the action 
or condition or the action or condition itself.
    However, the mere identification of any threat(s) does not 
necessarily mean that the species meets the statutory definition of an 
``endangered species'' or a ``threatened species.'' In determining 
whether a species meets either definition, we must evaluate all 
identified threats by considering the species' expected response and 
the effects of the threats--in light of those actions and conditions 
that will ameliorate the threats--on an individual, population, and 
species level. We evaluate each threat and its expected effects on the 
species, then analyze the cumulative effect of all of the threats on 
the species as a whole. We also consider the cumulative effect of the 
threats in light of those actions and conditions that will have 
positive effects on the species, such as any existing regulatory 
mechanisms or conservation efforts. The Secretary determines whether 
the species meets the definition of an ``endangered species'' or a 
``threatened species'' only after conducting this cumulative analysis 
and describing the expected effect on the species.
    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

[[Page 23873]]

framework for evaluating the foreseeable future on a case-by-case basis 
which is further described in the 2009 Memorandum Opinion on the 
foreseeable future from the Department of the Interior, Office of the 
Solicitor (M-37021, January 16, 2009; ``M-Opinion,'' available online 
at ). The foreseeable future extends as far into the future as 
the U.S. Fish and Wildlife Service (and the National Marine Fisheries 
Service for species under the agency's jurisdiction) can make 
reasonably reliable predictions about the threats to a species and the 
species' responses to those threats. We need not identify the 
foreseeable future in terms of a specific period of time. We will 
describe the foreseeable future on a case-by-case basis, using the best 
scientific and commercial data available and taking into account 
considerations such as the species' life-history characteristics, 
threat projection timeframes, and environmental variability. In other 
words, the foreseeable future is the period of time over which we can 
make reasonably reliable predictions. ``Reliable'' does not mean 
``certain''; it means sufficient to provide a reasonable degree of 
confidence in the prediction, in light of the conservation purposes of 
the Act.

Analytical Framework

    The SSA report documents the results of our comprehensive 
biological review of the best scientific and commercial data available 
regarding the status of the species, including an assessment of the 
potential threats to the species. The SSA report does not represent our 
decision on whether the species should be proposed for listing as an 
endangered or threatened species under the Act. However, it does 
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.
    To assess ghost orchid viability, we used the three conservation 
biology principles of resiliency, redundancy, and representation 
(Shaffer and Stein 2000, pp. 306-310). Briefly, resiliency is the 
ability of the species to withstand environmental and demographic 
stochasticity (for example, wet or dry, warm or cold years); redundancy 
is the ability of the species to withstand catastrophic events (for 
example, droughts, large pollution events); and representation is the 
ability of the species to adapt to both near-term and long-term changes 
in its physical and biological environment (for example, climate 
conditions, pathogens). In general, species viability will increase 
with increases in resiliency, redundancy, and representation (Smith et 
al. 2018, p. 306). Using these principles, we identified the species' 
ecological requirements for survival and reproduction at the 
individual, population, and species levels, and described the 
beneficial and risk factors influencing the species' viability.
    The SSA process can be categorized into three sequential stages. 
During the first stage, we evaluated the individual species' life-
history needs. The next stage involved an assessment of the historical 
and current condition of the species' demographics and habitat 
characteristics, including an explanation of how the species arrived at 
its current condition. The final stage of the SSA process involved 
making predictions about the species' future condition, including 
responses to positive and negative environmental and anthropogenic 
influences. Throughout all of these stages, we used the best scientific 
and commercial data available to characterize viability as the ability 
of a species to sustain populations in the wild over time, which we 
then used to inform our regulatory decision.
    The following is a summary of the key results and conclusions from 
the SSA report; the full SSA report can be found at Docket No. FWS-R4-
ES-2025-0022 on .

Summary of Biological Status and Threats

    In this discussion, we review the biological condition of the ghost 
orchid and its resources, and the threats that influence the species' 
current and future condition, in order to assess the species' overall 
viability and the risks to that viability.

Species Needs

    The ghost orchid is a long-lived perennial flowering plant found in 
high humidity, shaded environments. It may take 15 years or more for a 
ghost orchid plant in the wild to first produce flowers (Houlihan et 
al. 2019, p.7). They are epiphytic, which means they require host trees 
as substrates to live on. Their root system keeps them attached to the 
host tree and provides the means for photosynthesis since ghost orchids 
are leafless. Like other orchids, for survival and germination, ghost 
orchids require a fungal symbiont. For ghost orchid, this fungal 
symbiont is a Ceratobasidium species recognized as distinct but not yet 
named (Johnson et al. 2023, p. 4). Ghost orchids primarily rely on just 
two pollinators, the fig sphinx moth and the pawpaw sphinx moth. These 
pollinators are necessary for cross-pollination and successful 
reproduction.
    In Florida, one of the most important ecological conditions 
necessary for ghost orchid survival is the presence of sufficiently wet 
conditions throughout the year. The year-round presence of standing or 
very slow-moving freshwater in slough and swamp habitats protects 
against occasional frost and provides the necessary conditions for 
seedling recruitment. Standing water conditions year-round also protect 
against intense wildfires from burning into the interior of these 
swamps and sloughs, which could damage or kill host trees. Ghost orchid 
habitat in Cuba is different; plants are found growing on semi-
deciduous hardwood host trees in areas with little or no standing water 
(M[uacute]jica et al. 2018, p. 573). However, in both Cuba and Florida 
ghost orchid plants colonize host trees with moist, corrugated or semi-
corrugated bark, which is necessary for seed germination (M[uacute]jica 
et al. 2018, p. 583).
    Regardless of the habitat, ghost orchid recruitment is dependent on 
having sufficiently wet conditions (even with little or no standing 
water) present throughout the year (M[uacute]jica et al. 2021, p. 8), 
likely because moist bark allows for the growth of its mycorrhizal 
fungal partner (M[uacute]jica et al. 2018, p. 583; M[uacute]jica et al. 
2021, p. 8). Without successful recruitment, populations will 
eventually become extirpated when the mature individuals perish 
(Rasmussen et al. 2015, p. 392). Therefore, resilient populations of 
ghost orchid need high seedling numbers and robust recruitment rates 
for population stability and growth (Chung et al. 2011, pp. 2034-2036; 
Ackerman et al. 2020, pp. 677-682). For the ghost orchid, at least 20-
25 percent of plants should be in the seedling stage to achieve a 
positive population growth rate (although having a percentage above 
this level does not guarantee population growth) (M[uacute]jica et al. 
2021, p. 4; Service 2025, p. 35).
    In summary, based upon the best available scientific and commercial 
information, and acknowledging existing uncertainties, we recognize 
that ghost orchids need host trees for a growth substrate; they need 
year-long standing water in Florida and wet conditions in both Florida 
and Cuba to facilitate mycorrhizal fungi relationships for successful 
recruitment and to protect against fire and frost (in Florida); and 
they need pollinators for successful reproduction to occur.

Threats (Stressors/Risk Factors/Etc.)

Illegal Collection (Poaching)
    Illegal collection or poaching is one of the primary, ongoing 
threats to ghost orchid populations throughout its range. Orchids as a 
group are highly prized and sought after by collectors for their beauty 
and diversity (Wraith and Pickering 2017, pp. 3410-3414; Fay 2018, p. 
2). The ghost orchid is one of the most desirable species for 
collection due to its rarity, unusual growth form, and overall stunning 
appearance. This desirability is enhanced by the difficulty in 
successfully growing the species in greenhouse settings (Service 2025, 
pp. 27-28). Poaching from wild populations endangers the viability of 
populations by removing the individuals most likely to contribute to 
reproduction and recruitment (e.g., flowering adults). In Florida, 
poaching is illegal under Chapter 5B-40 Preservation of Native Flora of 
Florida (FL Admin Code R 5B-40).
    In the last several decades, poaching has affected many ghost 
orchid populations, even in protected conservation areas. For example, 
recent poaching in the summer of 2020 at Big Cypress National Preserve 
likely had a significant impact on that population (Angelo 2024, p. 4). 
Although Big Cypress National Preserve staff have taken important steps 
to reduce the accessibility of the site, such as locking the gate to 
the access road near the population and discontinuing maintenance of 
the road, these areas remain vulnerable to poaching and disturbance. 
Additionally, there are several unauthorized flagged trails to ghost 
orchid sites within Big Cypress National Preserve that contribute to 
this threat. The unauthorized flagging is an ongoing problem and has 
been discovered and removed by Big Cypress National Preserve staff as 
recently as summer 2024 (Angelo 2024, p. 5).
    In another population at Fakahatchee Strand Preserve State Park, 
where individual ghost orchid plants are closely monitored, 10 plants 
were illegally collected between 2005 and 2020, which represents 8 
percent of plants monitored (Owen 2024, entire). Even as recently as 
2023, poachers were caught at Fakahatchee Strand Preserve State Park 
attempting to steal reproductively mature ghost orchid plants (Fox 13 
Tampa Bay 2024, entire). Some poaching has been documented or is 
presumed to have occurred at Coastal Transition Site 1 (Franklin 2024, 
entire) and Naples Botanical Garden, but this threat is considered 
minimal here and/or has been reduced recently (Owen 2024, entire). 
While poaching has not been specifically documented at the population 
within Collier-Seminole State Park, local managers believe it has been 
a problem in the past (Patel 2024, entire). It is likely that poaching 
has occurred at other Florida populations and has simply not been 
recorded, since populations are hard to access and not all are visited 
regularly. In Guanahacabibes National Park in Cuba, poaching of at 
least one mature ghost orchid has been documented since 2015 (Zettler 
2024, entire) and poaching of 42 individuals of another co-occurring 
epiphytic orchid (Broughtonia cubensis) were documented 
(Ravent[oacute]s et al. 2015, p. 180).
    What is especially detrimental to the health of ghost orchid 
populations is poachers' preference for reproductively mature plants, 
which can take 15 years or more to mature and are crucial to the 
production of future generations. As such, the population level effects 
may not be realized for many years after poaching has occurred. Even 
though plants have been made available in the commercial horticultural 
trade in recent years, poachers are still persistent in their efforts 
(Herdman 2024, entire). Poaching is an ongoing rangewide threat that is 
highly likely to continue into the future.
Habitat Degradation Related to Hydrological Changes
    Canalization, ditching, and groundwater extraction have caused 
hydrological changes and habitat modifications in areas occupied by the 
ghost orchid. Southwestern Florida has undergone transformative 
canalization over the last century to divert water away from 
residential areas and roads (Service 2025, p. 18). Ditching associated 
with past cypress logging has also contributed to alteration and 
diversion of natural water flow (Fakahatchee Strand Preserve State Park 
Unit Management Plan 2014, p. 19). Groundwater extraction for crops and 
residential use has markedly increased in the last several decades as 
both agricultural land use and human population size increased in the 
region (Florida Regional Economic Analysis Project 2023, pp. 1-2). 
These hydrological changes to the landscape have contributed to reduced 
water flow and water availability to the adjacent natural areas that 
the ghost orchid occupies (Clem and Duever 2019, pp. 365-367). 
Increased water recession rates during the dry season have been 
documented in the Corkscrew Swamp Sanctuary (Clem and Duever 2019, p. 
365), Collier-Seminole State Park (Collier-Seminole State Park Unit 
Management Plan 2004, p. 18), and Big Cypress National Preserve 
(National Park Service 2021, entire) in recent years.
    These documented hydrological changes within the ghost orchid range 
in Florida present several threats to populations. Ghost orchid 
recruitment depends on having sufficiently wet conditions present 
throughout the year (M[uacute]jica et al. 2021, p. 8). As noted above, 
without successful recruitment, populations will eventually become 
extirpated when mature individuals perish and are not replaced by 
younger generations (Rasmussen et al. 2015, p. 392). Drier conditions 
also increase potential exposure of ghost orchids to frost, which they 
are not adapted to survive and are largely intolerant. Historically, 
the long hydroperiods and high humidity of the ghost orchid's swamp and 
slough habitats would protect these areas from frosts. With recent 
decreases in year-round standing water conditions, frosts have become 
more common and have contributed to extirpation of the only population 
at Six Mile Cypress Slough Preserve in Lee County, Florida (Greeno 
2024, entire), possibly 1 of 3 subpopulations at Coastal Transition 
Site 1 (Florida DEP 2024, entire), and 35 or more plants at Fakahatchee 
Strand Preserve State Park (Owen 2024, entire). Drier conditions have 
also been observed in Collier-Seminole State Park and Big Cypress 
National Preserve in recent years, which can increase the negative 
impacts from frost in these areas (Florida DEP 2004, p. 18).
    As a result of the hydrological change and subsequent drier 
conditions, wildfires are now more frequent and represent a significant 
threat to Florida ghost orchid populations (Clem and Duever 2019, 
entire; Clem and Cornell 2021, entire; NatureServe 2021, pp. 5, 7). A 
wildfire in 2018 at Picayune Strand State Park is presumed to have 
extirpated one ghost orchid subpopulation (Sowell 2024, entire). The 
Silver King Wildfire in 2020 at Big Cypress National Preserve burned 
over 600 acres (243 hectares) and came within 6.5 feet (2 meters) of 
the closest known ghost orchid, just narrowly missing the population 
(Angelo 2024, p. 4). Nearby, the fire burned into the peat ground layer 
and burned tree roots; had the fire reached just slightly farther, 
ghost orchid host trees would have been directly impacted. Even without 
reaching the host trees themselves, an intense fire in such close 
proximity may still have negative future effects on ghost orchids 
nearby, as the increased sunlight reaching the understory where the 
plants are located can increase temperature and decrease humidity

[[Page 23875]]

(Herdman 2024, entire). Hydrological changes are an ongoing, rangewide 
threat that is likely to continue into the future.
Hurricanes and Saltwater Intrusion
    Hurricanes are regularly occurring natural weather events that 
affect all parts of the ghost orchid range. Although hurricanes have 
always been a component of Florida and Cuba's climate, their intensity 
and frequency are increasing (Jay et al. 2023, p. 16). Category 4 and 5 
hurricanes produce high winds (greater than 130 miles per hour) and can 
uproot and kill host trees or damage branches, thereby killing any 
ghost orchid plants on host trees and their branches. A single host 
tree can support multiple ghost orchid plants. Therefore, the loss of 
even one host tree could result in the loss of several ghost orchids. 
Furthermore, the sudden and near complete loss of leaf canopy over 
ghost orchid populations can have significant impacts to the species' 
survival and health. Typically, ghost orchids are shaded from intense 
sun exposure from the summer to early fall. The deciduous leaf canopy 
is gradually lost over a period of two months in mid to late fall; 
however, hurricanes can result in complete loss of leaves during the 
storm. Such a dramatic change can expose ghost orchids to direct 
sunlight and make them more prone to heat and desiccation stress. These 
orchids may not immediately perish but may instead decline in health 
over 1 to 2 years and then die (Owen 2024, entire). Any ghost orchids 
occurring higher in the canopy would be especially susceptible to this 
heat and desiccation threat, as well as to direct wind damage from 
storms (Clem 2024a, entire).
    Impacts from hurricanes have already been observed in multiple 
populations. For example, at the Florida Panther National Wildlife 
Refuge, at least 48 orchids died after their host tree fell or had 
branches damaged during Hurricane Irma in 2017 (M[uacute]jica et al. 
2021, p. 8). Additionally, the number of seedlings observed in that 
population dropped in the following 2 years after the hurricane, 
demonstrating the negative demographic effects from storms 
(M[uacute]jica et al. 2021, p. 3). The recent 30 percent decline of a 
population at Big Cypress National Preserve is also directly 
attributable to Hurricane Irma. A survey of the largest population 
within the preserve took place just a few months before the storm and 
then subsequently following the storm documenting the loss of numerous 
host trees. Additionally, loss of ghost orchids due to changes in 
canopy cover and humidity in the damaged area of the slough was also 
evident (Angelo 2024, entire). The loss of one ghost orchid at Audubon 
Corkscrew Swamp Sanctuary also occurred as a direct result of Hurricane 
Irma (Clem 2024b, p. 1).
    Strong hurricanes also produce flooding events from a high amount 
of rainfall over a short period of time, which greatly increases normal 
water levels in ghost orchid habitat. Some plants that would normally 
be located above the water line on their host tree become inundated as 
a direct result of this flooding and, if prolonged, can perish. Indeed, 
this type of mortality was observed at the Florida Panther National 
Wildlife Refuge following Hurricane Irma (M[uacute]jica et al. 2021, 
pp. 3-4) and was observed at Fakahatchee Strand Preserve State Park 
following Hurricane Wilma (Owen 2024, entire).
    Storm surges and saltwater intrusion are also threats affecting the 
ghost orchid. Both the increased frequency and severity of storm surge 
events after hurricanes and increased water salinity in wetland 
habitats threaten coastal populations. At Coastal Transition Site 1, 
measured surface water salinities have reached as high as 2.0 part per 
trillion (ppt) in areas occupied by ghost orchids; soil porewater 
salinities at this level are high enough to kill off host canopy trees 
(Florida DEP 2024, entire). Nearby surface water salinities have been 
measured even higher at up to 5.3 ppt, which has led to complete canopy 
die-off and a steep decline in epiphyte diversity.
    In summary, the increased frequency and intensity of hurricanes 
over the last couple of decades has damaged host trees and reduced 
overstory shading, which along with storm surges and associated 
saltwater intrusion into the ghost orchid's freshwater habitat, has led 
to a significant reduction in ghost orchid populations and their 
habitat, thereby reducing overall population resiliency and the 
species' redundancy. The threats of frequent and intense hurricanes are 
occurring rangewide and are likely to continue into the future.

Conservation Efforts and Regulatory Mechanisms

    Ghost orchid is currently State-listed as an endangered species by 
Florida's Department of Agriculture and Consumer Services (FDACS) and 
is included in the Florida Regulated Plant Index (endangered, 
threatened and commercially exploited species) as defined in Chapter 
5B-40 Preservation of Native Flora of Florida (FL Admin Code R 5B-40). 
The State listing does not provide any direct habitat protection or 
automatic conservation protections for the species. State government 
regulations associated with this listing require both written 
permission from the owner or legal representative and a permit issued 
by FDACS to collect or remove plants listed as endangered on the 
Florida Regulated Plant Index. Additionally, Title 62D-2.013, Park 
Property and Resources, of the Florida Administrative Code (FL Admin 
Code R 62D-2.013) prohibits the removal, destruction, or damage of 
plants from Florida Department of Environmental Protection and Division 
of Recreation and Park properties. This regulation provides protection 
for the populations that occur on State lands but relies on public 
awareness and voluntary adherence to the Florida administrative code 
since monitoring is limited. As indicated in the Poaching section 
above, these State-level legal restrictions have not dissuaded 
poachers.
    Additionally, all orchid species, including the ghost orchid, are 
covered under the Convention on International Trade in Endangered 
Species of Wild Fauna and Flora treaty under Appendix II, which 
requires permits for the trade of plants across international borders, 
whether for commercial, scientific, or personal purposes (American 
Orchid Society 2024, p. 1). However, this treaty does not regulate any 
collection or movement of plants within an individual country and does 
not appear to be a deterrent against ghost orchid poaching.
    In 2024, the Florida Fish and Wildlife Conservation Commission 
(FWC) finalized an addendum to the Florida's State Wildlife Action Plan 
that added almost 600 plant species, including the ghost orchid, to its 
list of Species of Greatest Conservation Need. However, even with this 
change, the State Wildlife Action Plan does not ensure specific 
conservation actions will be accomplished for any particular plant 
species. Currently, almost all known extant populations are located on 
public, protected lands, often with mixed ownership and management. 
These include both State and federally managed lands, specifically 
Florida Department of Environmental Protection State Parks, National 
Wildlife Refuges, National Park Service units, Florida Forest Service 
lands (historically but not extant), Lee County lands (historically but 
not extant), and in Cuba at Guanahacabibes National Park (see table 1). 
Additionally, there is also a privately owned and protected site at the 
National Audubon Society's Corkscrew Swamp Sanctuary.
    The level of monitoring and species-specific management at these 
protected sites varies. For example, at the

[[Page 23876]]

Fakahatchee Strand Preserve State Park, the most recent management plan 
lists the ghost orchid as a known imperiled species within the park. As 
such, it lists hydrological maintenance, restoration and protection 
from visitor impacts as the main management actions for the species and 
monitoring efforts. The park management plan calls for a population 
census to count the entire population with demographic analysis, 
including mortality, reproduction, emigration, and immigration (Florida 
DEP 2014, pp. 38-56). Conversely, the Collier-Seminole State Park's 
management plan identifies the ghost orchid as a known species within 
the park, but no species-specific management or monitoring actions are 
listed (Florida DEP 2004, p. 84). However, their management goals of 
controlling invasive exotic plant species and restoring hydrology to 
pre-drainage conditions would likely benefit ghost orchid. At Florida 
Panther National Wildlife Refuge, the population is monitored annually 
for survival, flowering, fruiting, and recruitment rates (Danaher 2024, 
entire). In their Natural Resource Prioritization Phase II Decision 
Report, the Florida Panther National Wildlife Refuge lists improving 
and conserving hydrology of forested and herbaceous wetlands as a goal 
to increase and/or maintain ghost orchid populations within slough 
habitats.
    While the ghost orchid is known for being difficult to grow in ex 
situ (e.g., outside of natural) conditions, recent research has made 
cultivation in greenhouses possible. One major step forward was the 
discovery of the fungal strain (Ceratobasidium), harvested from ghost 
orchid roots in the wild, that could be used in the lab to greatly 
increase seed germination and successful seedling development rates 
(Hoang et al. 2016, p. 383). Like all orchid species, ghost orchid 
seeds and seedlings require a fungal mycorrhizal symbiont. Thus, 
culturing the seeds with its specific Ceratobasidium fungal partner has 
allowed for increased growth success of ghost orchids. Additionally, 
although ghost orchids are considered intolerant of desiccation in 
their natural, high-humidity environments, they appear to be somewhat 
tolerant of desiccation in greenhouse settings (Coopman and Kane 2019, 
p. 64). This discovery may allow for the direct use of greenhouse-
derived plants for field restoration and conservation of the species 
(Coopman and Kane 2019, pp. 69, 106).
    These advancements in greenhouse propagation could have important 
conservation impacts for future restoration of ghost orchids. Such 
efforts began in 2015 with the first translocation study in which ghost 
orchids attached to burlap in the greenhouse were transplanted to host 
trees at Florida Panther National Wildlife Refuge. Survival of plants 
was about 90 percent after 1 year and about 73 percent 20 months later 
(Kane 2023, entire). Following this success, 120 six-year-old ghost 
orchids grown from culture were directly outplanted to the Florida 
Panther National Wildlife Refuge. Survival of these plants decreased 
over time; in 2023, only 34 of the original 120 plants (28 percent) 
remained. Additionally, despite flowering and developing seed capsules, 
all fruits from these plants were aborted before fully maturing. One 
likely explanation for this fecundity failure is inbreeding depression, 
as all outplants were derived from a single seed capsule collected from 
the Florida Panther National Wildlife Refuge (Herdman 2024, entire). 
Therefore, this population of outplants is not considered viable, as 
successful reproduction has not been achieved.

Cumulative Effects

    We note that, by using the SSA framework to guide our analysis of 
the scientific information documented in the SSA report, we have 
analyzed the cumulative effects of identified threats and conservation 
actions on the species. To assess the current and future condition of 
the species, we evaluate the effects of all the relevant factors that 
may be influencing the species, including threats and conservation 
efforts. Because the SSA framework considers not just the presence of 
the factors, but to what degree they collectively influence risk to the 
entire species, our assessment integrates the cumulative effects of the 
factors and replaces a standalone cumulative-effects analysis.

Current Condition

    For the purposes of evaluating current conditions, we used analysis 
units to evaluate population resiliency. Analysis units are based 
largely on management areas and represent discrete groups and/or 
populations of the ghost orchid. Most analysis units have just one area 
where ghost orchids occur, but some analysis units consist of separate 
locations that we refer to as subpopulations. When referring to ghost 
orchids within an analysis unit, we use the term population or 
subpopulation, as appropriate.
    To assesses resiliency, we evaluated seven components that relate 
to the species' needs and its population demography and habitat 
conditions. Resiliency for each analysis unit was categorized as low, 
moderate, or high based on information from documented studies, 
available unpublished information, and expert opinion (see table 2, 
below). In some instances, a low-moderate or moderate-high designation 
was appropriate. For example, for the Florida Panther National Wildlife 
Refuge analysis unit, the number of seedlings and percent of seedlings 
can vary from year to year, thus, in order to capture this variation, 
we considered recent seedling abundance data collected over a six-year 
period (2015-2020). Overall, we categorized the Florida Panther 
National Wildlife Refuge as moderate-high because the first four years 
of monitoring, seedling abundance was high (range 24-44 percent), but 
the last two years of monitoring seedling abundance was moderate (14 
percent) and low (0 percent) (M[uacute]jica et al. 2021, p. 4). 
Therefore, for this six-year period, capturing interannual variation, 
we consider the current condition of seedling abundance to be moderate-
high for this analysis unit (Service 2025, pp. 37-38). After resiliency 
categories were assigned, we numerically scored each population 
demography and habitat condition category (high = 3, moderate = 2, low 
= 1) and then calculated the average current condition resiliency for 
each analysis unit (see table 3, below). Please see the SSA report for 
a detailed description of current resiliency methods and results 
(Service 2025, pp. 29-43).

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

    Based on our current condition analysis, no ghost orchid 
populations are considered to have high resiliency. This is largely due 
to all analysis units experiencing declines in recent years, and all 
analysis units are in low condition for multiple demographic and 
habitat factors. Florida Panther National Wildlife Refuge and 
Guanahacabibes National Park are the only two analysis units with 
moderate resiliency. Florida Panther National Wildlife Refuge has one 
of the larger populations (approximately 275 plants) and seedling 
abundance and fruit production are good in most years with little to no 
threat of poaching. However, recent hurricane impacts have been 
significant, and this analysis unit has a declining population trend 
(approximately 70 percent between 2015-2023) (Danaher 2024, entire). 
Additionally, hydrological impacts have been significant due to the 
widespread alteration of natural water flow from surrounding roads and 
canals. Thus, the Florida Panther National Wildlife Refuge analysis 
unit received an overall moderate resiliency score.
    Guanahacabibes National Park also has a relatively large population 
(approximately 230 plants) with some seedling and reproductive output, 
and hydrological impacts do not pose a threat due to the different type 
of habitat utilized by the species in Cuba. However, similar to the 
Florida Panther National Wildlife Refuge, hurricanes have had 
significant impacts to the Guanahacabibes National Park analysis unit. 
After Hurricane Ivan in 2004, a significant population decline (59 
percent) was documented (Wiegand et al. 2013, pp. 444-447). If the 
greater frequency and intensity of hurricanes continues in the near 
term, it is estimated that this population could be extirpated by 2040 
(Ravent[oacute]s et al. 2015, pp. 182-184). Additionally, at least one 
mature ghost orchid has been poached from this population in the last 
decade (Zettler 2024, entire) and in 2010, 42 individuals of another 
co-occurring epiphytic orchid (Broughtonia cubensis) were poached from 
the park (Ravent[oacute]s et al. 2015, p. 180).
    Although Fakahatchee Strand Preserve State Park is one of the 
larger populations (approximately 180 to 280 plants) it has an overall 
low resiliency due to a high rate of poaching, low seedling abundance, 
poor seedling survival rates, and, in most years, low reproductive 
output (Owen 2024, entire). Furthermore, this analysis unit has 
experienced a steep population decline of approximately 60-77 percent 
over the last 30 years Owen 2024, entire).
    Similarly, the Big Cypress National Preserve population, although 
larger in size (around 300 plants), has a documented decline of at 
least 30 percent since 2017 (Angelo 2024, entire), has low seedling 
abundance or fruit production and suffered large losses after Hurricane 
Irma in 2017. Ghost orchids within this analysis unit also face a high 
threat of poaching with significant poaching documented in recent years 
(Angelo 2024, entire). The habitat within the Big Cypress National 
Preserve has also been much drier in recent years and an intense 2020 
wildfire reached dangerously close to ghost orchid areas. Together, 
these factors resulted in an overall low resiliency score for Big 
Cypress National Preserve.
    Population trends for the Hendry County analysis unit are unknown 
as the presence of this population is known from only one survey in 
2023. We know the population is small (less than 40 plants, but likely 
between 10 and 20 plants), reproductive output is likely low, and 
poaching is apparently not an issue (no evidence of poaching, to date) 
(Nesmith 2024, entire; Owen 2024, entire). Thus, Hendry County site

[[Page 23878]]

is considered to have low to moderate resiliency.
    Coastal Transition Site 1 is considered to have low resiliency and 
consists of a small population (approximately 19 plants) with little 
seedling abundance and survival. This analysis unit has significantly 
decreased in size, with two of the three areas with ghost orchids 
extirpated from impacts related to poaching, hurricanes, storm surges, 
and saltwater intrusion. Surface water salinities in this analysis unit 
have reached concerning levels and the remaining 19 plants are 
extremely susceptible to impacts from saltwater intrusion as well as 
other threats (Florida DEP 2024, pers. comm.; Service 2025, p. 22).
    Audubon Corkscrew Swamp Sanctuary is one of the most well-known 
populations due to its high flowering rates (plants flower regularly 
with many flowers on each plant), unusually high height in its host 
trees, and easy accessibility. However, this population is very small 
with currently only two plants documented. This analysis unit has been 
significantly impacted by drier hydrologic conditions and recent 
hurricane damage, giving it an overall low resiliency.
    The Collier-Seminole State Park analysis unit scored low for every 
demographic factor, and the population consists of just four or five 
plants (Patel 2024, entire). These factors, combined with the 
hydrologic and hurricane impacts affecting the analysis unit, results 
in low overall resiliency.
    Lastly, the Naples Urban Site scored low for total abundance 
because it consists of only 31 plants. Though many of these plants are 
reproductively mature, this population experienced a decline of 
approximately 25 percent from 2001 to 2017 due to impacts from 
hurricanes (Owen 2024, entire). Given this information, we consider 
Naples Urban Site to have low resiliency.
Redundancy
    Redundancy is the ability of a species to withstand catastrophes. 
We can best gauge redundancy by analyzing the number and distribution 
of populations relative to the scale of anticipated species-relevant 
catastrophic events. Because three ghost orchid populations are 
considered recently extirpated and most extant ghost orchid populations 
are in low or low to moderate resiliency and are distributed in a 
narrow geographic area (limited range in Florida, only one population 
in Cuba, and no connectivity between the Florida and Cuba populations), 
redundancy for this species is limited. A single catastrophic event, 
such as a strong hurricane, could impact a large component of the 
species' range at one time and cause significant declines at multiple 
sites simultaneously. Such impacts have already been observed following 
Hurricane Irma in 2017 when at least five out of eight analysis units 
in Florida (Big Cypress National Preserve, Fakahatchee Strand Preserve 
State Park, Audubon Corkscrew Swamp Sanctuary, Coastal Transition Site 
1, and Florida Panther National Wildlife Refuge) and the Guanahacabibes 
National Park analysis unit in Cuba, were negatively affected at the 
same time. With hurricane frequency and intensity projected to increase 
in the future, negative population-level to species-level impacts could 
likely happen again.
Representation
    Representation reflects a species' adaptive capacity to respond to 
changing near-term and long-term environmental conditions and can be 
characterized by the breadth of genetic and ecological diversity within 
and among populations. A species' adaptive capacity is essential for 
viability, as species need to adapt to their continuously changing 
environments (Nicotra et al. 2015, p. 1269). We do not have information 
on the genetic diversity within or among ghost orchid populations 
across the species' range, though the need for such studies has been 
highlighted (Danaher et al. 2020, p. 682; Houlihan et al. 2019, p. 7) 
and some genetic work has begun but is not yet available (Danaher 2024, 
entire; Herdman 2024, entire).
    Different habitat types within the species' range, or morphological 
or phenological differences, can also reflect a species' ability to 
adapt to changing conditions. One of the biggest distinctions between 
the Florida and Cuba populations is the type of habitat occupied. While 
all current ghost orchids in Florida occur in long hydroperiod 
subtropical dome swamps, strand swamps, and sloughs, plants in Cuba's 
extant population occur in a tropical semi-deciduous forest with soils 
characterized as fractured reef limestone, and little or no standing 
water present (Ravent[oacute]s et al. 2015, p. 180; M[uacute]jica et 
al. 2018, p. 573). It is possible that at least some habitat 
differences may be attributable to the difference in climate between 
the two regions, with subtropical southwest Florida occasionally 
experiencing frost conditions while tropical western Cuba never 
experiences frost. The southwest Florida populations may require long 
hydroperiod environments to protect ghost orchids from frost events, 
while the Cuba populations do not experience frost and therefore lack 
this requirement.
    Another difference between the Florida and Cuba populations is host 
tree species availability, with most Florida ghost orchids primarily 
found growing on just two species of trees (Florida water ash and pond 
apple), while ghost orchids in Cuba can be primarily found growing on 5 
different host tree species, though 18 species of host tree have been 
recorded (M[uacute]jica et al. 2018, p. 577). There is no overlap in 
host tree species between the two regions, as nearly all the trees that 
ghost orchids grow on in Cuba do not occur in Florida and the host 
trees of Florida are much less common in Cuba. However, in both 
regions, ghost orchids prefer host trees with moist, corrugated or 
semi-corrugated bark (M[uacute]jica et al. 2018, p. 581).
    There is also a distinct difference in the phenology of ghost 
orchids in Florida compared to those found in Cuba. While flowering 
typically occurs from May to August in Florida, flowering in Cuba 
occurs later in the year, typically from October to December 
(M[uacute]jica et al. 2018, p. 575). Consequently, there is also a 
distinct difference in fruiting times between the two regions, with 
Florida ghost orchids typically fruiting in January to April and Cuba 
plants fruiting from May to June (M[uacute]jica et al. 2018, p. 575). 
One morphological difference between ghost orchids in these two regions 
is nectar spur (serves as the pathway for pollinators to access nectar) 
length, which on average appears to be several centimeters longer in 
the Cuba population compared to those in Florida, which could indicate 
a genetic component causing this distinction (Zettler 2024, entire).
    Although there are regional differences in ghost orchid habitat, 
morphology, and phenology, it is also important to recognize the ways 
in which the species' life history and ecological associations remain 
constant across its range. For example, in both Florida and Cuba, 
plants appear to prefer growing on trees with corrugated or semi-
corrugated bark on average about 3 to 6 feet (0.9 to 1.8 meter) above 
ground, though Florida plants may grow slightly higher, probably to 
accommodate the higher water levels (M[uacute]jica et al. 2018, p. 
581). Additionally, flowers in both regions are pollinated primarily by 
two species of moths (fig sphinx moth and pawpaw sphinx moth), and 
ghost orchids in both regions need to form symbiotic relationships with 
mycorrhizal fungi. While the presence/absence of frost

[[Page 23879]]

distinguishes the two regions, other climatic conditions such as 
average total annual rainfall and average annual temperature are 
similar between Florida and Cuba (M[uacute]jica et al. 2018, p. 575).
    Taken altogether, there are some differences between the two main 
regions of occurrence (Florida and Cuba), which reflect some degree of 
representation, but there is little if any difference within ghost 
orchid populations in Florida where most ghost orchids are currently 
located. In Florida, the species is highly dependent on habitats with 
standing water year-round and just a few host tree species. In both 
Cuba and Florida, ghost orchids are dependent upon moist bark for 
seedling germination, a specific type of mycorrhizal fungal 
relationship, and two species of pollinators. Thus, overall, the 
representation of ghost orchid is considered to be relatively low.
Summary of Current Condition
    Historically, ghost orchid occurred in 12 analysis units. Two 
analysis units in Florida and one analysis unit in Cuba have recently 
extirpated populations. Thus, ghost orchid currently occurs in nine 
analysis units, eight of these are in Florida and one is in Cuba. In 
Florida, six analysis units are considered to have low resiliency; one 
analysis unit is considered to have low to moderate resiliency; and one 
analysis unit is considered to have moderate resiliency. In Cuba, only 
one analysis unit has an extant ghost orchid population and is 
considered to have moderate resiliency. All analysis units have 
declining populations. Overall, the species has low abundance within 
each analysis unit with no more than 300 individuals within any 
analysis unit; most contain less than 40 plants.
    With declining population health (overall low resiliency due to low 
abundances and declining habitat conditions) coupled with a relatively 
small geographic extent and the extirpation of recent populations (low 
redundancy), and relatively low adaptive capacity, the species now 
possesses limited ability to withstand inherent stochasticity 
(environmental, demographic, and genetic), catastrophic events 
(hurricanes, wildfire, frost), and other changing environmental 
conditions (storm surge and saltwater intrusion).

Future Condition

    As part of the SSA, we also developed a future condition analysis 
which provides a summary of the primary threats to the species and how 
these threats are projected to continue to impact ghost orchid 
viability. Because we determined that the current condition of ghost 
orchid is consistent with an endangered species (see Determination of 
Ghost Orchid Status, below), we are not presenting the results of the 
future scenarios in this proposed rule. Please refer to the SSA report 
(Service 2025) for the full analysis of future scenarios.

Determination of Ghost Orchid's Status

    Section 4 of the Act (16 U.S.C. 1533) and its implementing 
regulations (50 CFR part 424) set forth the procedures for determining 
whether a species meets the definition of an endangered species or a 
threatened species. The Act defines an ``endangered species'' as a 
species in danger of extinction throughout all or a significant portion 
of its range and a ``threatened species'' as a species likely to become 
an endangered species within the foreseeable future throughout all or a 
significant portion of its range. The Act requires that we determine 
whether a species meets the definition of an endangered species or a 
threatened species because of any of the following factors: (A) The 
present or threatened destruction, modification, or curtailment of its 
habitat or range; (B) overutilization for commercial, recreational, 
scientific, or educational purposes; (C) disease or predation; (D) the 
inadequacy of existing regulatory mechanisms; or (E) other natural or 
manmade factors affecting its continued existence.

Status Throughout All of Its Range

    After evaluating threats to the ghost orchid and assessing the 
cumulative effect of the threats under the Act's section 4(a)(1) 
factors, we find that the viability of the species is currently at 
risk. The primary threats currently impacting the species are poaching 
(especially of mature plants) (Factor B), habitat degradation (related 
to hydrological changes) (Factor A), and the increased intensity and 
frequency of hurricanes that cause damage to or loss of the species' 
host trees and overstory shading and impacts from saltwater intrusion 
(Factor E). Overall, the species has relatively low abundance with no 
more than 300 plants within any analysis unit; most analysis units have 
less than 40 plants (see table 1). All analysis units have declining 
populations, and all analysis units have experienced negative impacts 
from hydrological change and recent hurricanes. Two-thirds of the 
analysis units have a significant amount of poaching pressure, 
including two analysis units with an especially high degree of poaching 
pressure (Fakahatchee Strand Preserve State Park and Big Cypress 
National Preserve). The two analysis units with especially high degree 
of poaching pressure also have the largest populations of ghost 
orchids. Of the nine analysis units that currently have ghost orchid 
populations, six analysis units are in overall low resiliency 
condition, one analysis unit has low to moderate resiliency, and two 
analysis units have moderate resiliency (see table 3, above). Three 
analysis units have been extirpated within the last 10 to 15 years.
    With declining population health (declining abundances and 
deteriorating habitat conditions) coupled with recent extirpation of 
populations and small geographic extent, the ghost orchid now has low 
resiliency, redundancy, and representation and possesses limited 
ability to withstand inherent stochasticity (environmental, 
demographic, and genetic), catastrophic events (hurricanes, frost, 
wildfire), and changing environmental conditions (storm surges and 
saltwater intrusion). Similar to Hurricane Irma in 2017, another 
catastrophic storm or hurricane, could severely impact multiple 
populations simultaneously, and further reduce the already low 
population resiliency and redundancy of the species. Additionally, 
given the ghost orchid's relatively narrow range, limited habitat types 
and number of host tree and pollinator species, and highly specific 
mycorrhizal fungi requirements, we consider the species to have 
relatively low representation.
    We do not find the ghost orchid meets the definition of a 
threatened species because the species is currently experiencing 
population declines resulting in low resiliency and has deteriorating 
habitat conditions driven or exacerbated by the identified threats. 
Because the ghost orchid has low redundancy and representation is 
limited, the species is vulnerable to a single catastrophic event like 
a hurricane that could impact the entire range. Thus, after assessing 
the best scientific and commercial data available, we determine that 
ghost orchid is in danger of extinction throughout all of its range.

Status Throughout a Significant Portion of Its Range

    Under the Act and our implementing regulations, a species may 
warrant listing if it is in danger of extinction or likely to become so 
within the foreseeable future throughout all or a significant portion 
of its range. We have determined that the ghost orchid is in danger of 
extinction throughout all of its range and accordingly did not 
undertake an analysis of any significant portion of

[[Page 23880]]

its range. Because the ghost orchid warrants listing as endangered 
throughout all of its range, our determination does not conflict with 
the decision in Center for Biological Diversity v. Everson, 435 F. 
Supp. 3d 69 (D.D.C. 2020), because that decision related to significant 
portion of the range analyses for species that warrant listing as 
threatened, not endangered, throughout all of their range.

Determination of Status

    Based on the best scientific and commercial data available, we 
determine that the ghost orchid meets the Act's definition of an 
endangered species. Therefore, we propose to list the ghost orchid as 
an endangered species in accordance with sections 3(6) and 4(a)(1) of 
the Act.

Available Conservation Measures

    Conservation measures provided to species listed as endangered or 
threatened species under the Act include recognition as a listed 
species, planning and implementation of recovery actions, requirements 
for Federal protection, and prohibitions against certain practices. 
Recognition through listing results in public awareness, and 
conservation by Federal, State, Tribal, and local agencies, foreign 
governments, private organizations, and individuals. The Act encourages 
cooperation with the States and other countries and calls for recovery 
actions to be carried out for listed species. The protection required 
by Federal agencies, including the Service, and the prohibitions 
against certain activities are discussed, in part, below.
    The primary purpose of the Act is the conservation of endangered 
and threatened species and the ecosystems upon which they depend. The 
ultimate goal of such conservation efforts is the recovery of these 
listed species, so that they no longer need the protective measures of 
the Act. Section 4(f) of the Act calls for the Service to develop and 
implement recovery plans for the conservation of endangered and 
threatened species. The goal of this process is to restore listed 
species to a point where they are secure, self-sustaining, and 
functioning components of their ecosystems.
    The recovery planning process begins with development of a recovery 
outline made available to the public soon after a final listing 
determination. The recovery outline guides the immediate implementation 
of urgent recovery actions while a recovery plan is being developed. 
Recovery teams (composed of species experts, Federal and State 
agencies, nongovernmental organizations, and stakeholders) may be 
established to develop and implement recovery plans. The recovery 
planning process involves the identification of actions that are 
necessary to halt and reverse the species' decline by addressing the 
threats to its survival and recovery. The recovery plan identifies 
recovery criteria for review of when a species may be ready for 
reclassification from endangered to threatened (``downlisting'') or 
removal from protected status (``delisting''), and methods for 
monitoring recovery progress. Recovery plans also establish a framework 
for agencies to coordinate their recovery efforts and provide estimates 
of the cost of implementing recovery tasks. Revisions of the plan may 
be done to address continuing or new threats to the species, as new 
substantive information becomes available. The recovery outline, draft 
recovery plan, final recovery plan, and any revisions will be available 
on our website as they are completed (/program/endangered-species) or from our Florida Ecological Services Office (see 
FOR FURTHER INFORMATION CONTACT).
    Implementation of recovery actions generally requires the 
participation of a broad range of partners, including other Federal 
agencies, States, Tribes, nongovernmental organizations, businesses, 
and private landowners. Examples of recovery actions include habitat 
restoration (e.g., restoration of native vegetation), research, captive 
propagation and reintroduction, and outreach and education. The 
recovery of many listed species cannot be accomplished solely on 
Federal lands because their range may occur primarily or solely on non-
Federal lands. To achieve recovery of these species requires 
cooperative conservation efforts on private, State, and Tribal lands.
    If this species is listed, funding for recovery actions may be 
available from a variety of sources, including Federal budgets, State 
programs, and cost-share grants for non-Federal landowners, the 
academic community, and nongovernmental organizations. In addition, 
pursuant to section 6 of the Act, the State of Florida would be 
eligible for Federal funds to implement management actions that promote 
the protection or recovery of the ghost orchid. Information on our 
grant programs that are available to aid species recovery can be found 
at: /service/financial-assistance.
    Although the ghost orchid is only proposed for listing under the 
Act at this time, please let us know if you are interested in 
participating in recovery efforts for this species. Additionally, we 
invite you to submit any new information on this species whenever it 
becomes available and any information you may have for recovery 
planning purposes (see FOR FURTHER INFORMATION CONTACT).
    Section 7 of the Act is titled Interagency Cooperation and it 
mandates all Federal action agencies to use their existing authorities 
to further the conservation purposes of the Act and to ensure that 
their actions are not likely to jeopardize the continued existence of 
listed species or adversely modify critical habitat. Regulations 
implementing section 7 are codified at 50 CFR part 402.
    Section 7(a)(2) of the Act states that each Federal action agency 
shall, in consultation with the Secretary, ensure that any action they 
authorize, fund, or carry out is not likely to jeopardize the continued 
existence of a listed species or result in the destruction or adverse 
modification of designated critical habitat. Each Federal agency shall 
review its action at the earliest possible time to determine whether it 
may affect listed species or critical habitat. If a determination is 
made that the action may affect listed species or critical habitat, 
formal consultation is required (50 CFR 402.14(a)), unless the Service 
concurs in writing that the action is not likely to adversely affect 
listed species or critical habitat. At the end of a formal 
consultation, the Service issues a biological opinion, containing its 
determination of whether the Federal action is likely to result in 
jeopardy or adverse modification.
    In contrast, section 7(a)(4) of the Act requires Federal agencies 
to confer with the Service on any action which is likely to jeopardize 
the continued existence of any species proposed to be listed under the 
Act or result in the destruction or adverse modification of critical 
habitat proposed to be designated for such species. Although the 
conference procedures are required only when an action is likely to 
result in jeopardy or adverse modification, action agencies may 
voluntarily confer with the Service on actions that may affect species 
proposed for listing or critical habitat proposed to be designated. In 
the event that the subject species is listed or the relevant critical 
habitat is designated, a conference opinion may be adopted as a 
biological opinion and serve as compliance with section 7(a)(2) of the 
Act.
    Examples of discretionary actions for the ghost orchid that may be 
subject to conference and consultation procedures under section 7 are 
management of Federal lands administered by the

[[Page 23881]]

National Park Service, U.S. Fish and Wildlife Service National Wildlife 
Refuges, and Department of Defense as well as actions that require a 
Federal permit (such as a permit from the U.S. Army Corps of Engineers 
under section 404 of the Clean Water Act (33 U.S.C. 1251 et seq.)) or 
actions funded by Federal agencies such as the Federal Highway 
Administration, Federal Aviation Administration, or the Federal 
Emergency Management Agency. Federal actions not affecting listed 
species or critical habitat--and actions on State, Tribal, local, or 
private lands that are not federally funded, authorized, or carried out 
by a Federal agency--do not require section 7 consultation. Federal 
agencies should coordinate with the Florida Ecological Services Office 
(see FOR FURTHER INFORMATION CONTACT) with any specific questions on 
section 7 consultation and conference requirements.
    The Act and its implementing regulations set forth a series of 
general prohibitions and exceptions that apply to endangered plants. 
The prohibitions of section 9(a)(2) of the Act, and the Service's 
implementing regulations codified at 50 CFR 17.61, make it illegal for 
any person subject to the jurisdiction of the United States to commit, 
to attempt to commit, to solicit another to commit or to cause to be 
committed any of the following acts with regard to any endangered 
plant: (1) import into, or export from, the United States; (2) remove 
and reduce to possession from areas under Federal jurisdiction; 
maliciously damage or destroy on any such area; or remove, cut, dig up, 
or damage or destroy on any other area in knowing violation of any law 
or regulation of any State or in the course of any violation of a State 
criminal trespass law; (3) deliver, receive, carry, transport, or ship 
in interstate or foreign commerce, by any means whatsoever and in the 
course of a commercial activity; or (4) sell or offer for sale in 
interstate or foreign commerce. Certain exceptions to these 
prohibitions apply to employees or agents of the Service, other Federal 
land management agencies, and State conservation agencies.
    We may issue permits to carry out otherwise prohibited activities 
involving endangered plants under certain circumstances. Service 
regulations governing permits for endangered plants are codified at 50 
CFR 17.62, and general Service permitting regulations are codified at 
50 CFR part 13. With regard to endangered plants, a permit may be 
issued for scientific purposes or for enhancing the propagation or 
survival of the species. The statute also contains certain exemptions 
from the prohibitions, which are found in sections 9 and 10 of the Act.

II. Critical Habitat

Background

    Section 4(a)(3) of the Act requires that, to the maximum extent 
prudent and determinable, we designate a species' critical habitat 
concurrently with listing the species. Critical habitat is defined in 
section 3(5)(A) of the Act as:
    (1) The specific areas within the geographical area occupied by the 
species, at the time it is listed in accordance with the Act, on which 
are found those physical or biological features
    (a) Essential to the conservation of the species, and
    (b) Which may require special management considerations or 
protection; and
    (2) Specific areas outside the geographical area occupied by the 
species at the time it is listed, upon a determination that such areas 
are essential for the conservation of the species.
    Our regulations at 50 CFR 424.02 define the geographical area 
occupied by the species as an area that may generally be delineated 
around species' occurrences, as determined by the Secretary (i.e., 
range). Such areas may include those areas used throughout all or part 
of the species' life cycle, even if not used on a regular basis (e.g., 
migratory corridors, seasonal habitats, and habitats used periodically, 
but not solely by vagrant individuals).
    Conservation, as defined under section 3(3) of the Act, means to 
use and the use of all methods and procedures that are necessary to 
bring an endangered or threatened species to the point at which the 
measures provided pursuant to the Act are no longer necessary. Such 
methods and procedures include, but are not limited to, all activities 
associated with scientific resources management such as research, 
census, law enforcement, habitat acquisition and maintenance, 
propagation, live trapping, and transplantation, and, in the 
extraordinary case where population pressures within a given ecosystem 
cannot be otherwise relieved, may include regulated taking.
    Critical habitat receives protection under section 7 of the Act 
through the requirement that each Federal action agency ensure, in 
consultation with the Service, that any action they authorize, fund, or 
carry out is not likely to result in the destruction or adverse 
modification of designated critical habitat. The designation of 
critical habitat does not affect land ownership or establish a refuge, 
wilderness, reserve, preserve, or other conservation area. Such 
designation also does not allow the government or public to access 
private lands. Such designation does not require implementation of 
restoration, recovery, or enhancement measures by non-Federal 
landowners. Rather, designation requires that, where a landowner 
requests Federal agency funding or authorization for an action that may 
affect an area designated as critical habitat, the Federal agency 
consult with the Service under section 7(a)(2) of the Act. If the 
action may affect the listed species itself (such as for occupied 
critical habitat), the Federal agency would have already been required 
to consult with the Service even absent the designation because of the 
requirement to ensure that the action is not likely to jeopardize the 
continued existence of the listed species. Even if the Service were to 
conclude after consultation that the proposed activity is likely to 
result in destruction or adverse modification of the critical habitat, 
the Federal action agency and the landowner are not required to abandon 
the proposed activity, or to restore or recover the species; instead, 
they must implement ``reasonable and prudent alternatives'' to avoid 
destruction or adverse modification of critical habitat.
    Under the first prong of the Act's definition of critical habitat, 
areas within the geographical area occupied by the species at the time 
it was listed are included in a critical habitat designation if they 
contain physical or biological features (1) which are essential to the 
conservation of the species and (2) which may require special 
management considerations or protection. For these areas, critical 
habitat designations identify, to the extent known using the best 
scientific data available, those physical or biological features that 
are essential to the conservation of the species (such as space, food, 
cover, and protected habitat).
    Under the second prong of the Act's definition of critical habitat, 
we can designate critical habitat in areas outside the geographical 
area occupied by the species at the time it is listed, upon a 
determination that such areas are essential for the conservation of the 
species.
    Section 4(b)(2) of the Act requires that we designate critical 
habitat on the basis of the best scientific data available. Further, 
our Policy on Information

[[Page 23882]]

Standards Under the Endangered Species Act (published in the Federal 
Register on July 1, 1994 (59 FR 34271)), the Information Quality Act 
(section 515 of the Treasury and General Government Appropriations Act 
for Fiscal Year 2001 (Pub. L. 106-554; H.R. 5658)), and our associated 
Information Quality Guidelines provide criteria, establish procedures, 
and provide guidance to ensure that our decisions are based on the best 
scientific data available. They require our biologists, to the extent 
consistent with the Act and with the use of the best scientific data 
available, to use primary and original sources of information as the 
basis for recommendations to designate critical habitat.
    When we are determining which areas should be designated as 
critical habitat, our primary source of information is generally the 
information compiled in the SSA report and information developed during 
the listing process for the species. Additional information sources may 
include any generalized conservation strategy, criteria, or outline 
that may have been developed for the species; the recovery plan for the 
species; articles in peer-reviewed journals; conservation plans 
developed by States and counties; scientific status surveys and 
studies; biological assessments; other unpublished materials; or 
experts' opinions or personal knowledge.
    Habitat is dynamic, and species may move from one area to another 
over time. We recognize that critical habitat designated at a 
particular point in time may not include all of the habitat areas that 
we may later determine are necessary for the recovery of the species. 
For these reasons, a critical habitat designation does not signal that 
habitat outside the designated area is unimportant or may not be needed 
for recovery of the species. Areas that are important to the 
conservation of the species, both inside and outside the critical 
habitat designation, will continue to be subject to: (1) Conservation 
actions implemented under section 7(a)(1) of the Act; (2) regulatory 
protections afforded by the requirement in section 7(a)(2) of the Act 
for Federal agencies to ensure their actions are not likely to 
jeopardize the continued existence of any endangered or threatened 
species; and (3) the prohibitions found in section 9 of the Act. 
Federally funded or permitted projects affecting listed species outside 
their designated critical habitat areas may still result in jeopardy 
findings in some cases. These protections and conservation tools will 
continue to contribute to recovery of the species. Similarly, critical 
habitat designations made on the basis of the best scientific data 
available at the time of designation will not control the direction and 
substance of future recovery plans, habitat conservation plans, or 
other species conservation planning efforts if new information 
available at the time of those planning efforts calls for a different 
outcome.

Prudency Determination

    Section 4(a)(3) of the Act, as amended, and implementing 
regulations (50 CFR 424.12) require that, to the maximum extent prudent 
and determinable, the Secretary shall designate critical habitat at the 
time the species is determined to be an endangered species or a 
threatened species. Our regulations (50 CFR 424.12(a)(1)) state that 
designation of critical habitat may not be prudent in circumstances 
such as, but not limited to, the following:
    (i) The species is threatened by taking or other human activity and 
identification of critical habitat can be expected to increase the 
degree of such threat to the species;
    (ii) The present or threatened destruction, modification, or 
curtailment of a species' habitat or range is not a threat to the 
species;
    (iii) Areas within the jurisdiction of the United States provide no 
more than negligible conservation value, if any, for a species 
occurring primarily outside the jurisdiction of the United States; or
    (iv) No areas meet the definition of critical habitat.
    As described above, there is currently an ongoing and imminent 
threat of take attributed to poaching for this species. The precise 
location of all ghost orchid populations are not publicly available. 
Although some locations are known to the public and have been accessed 
by poachers, other population's locations have been kept confidential 
to deter poaching. For example, the Florida Natural Areas Inventory, 
which maintains a comprehensive database of the biological resources in 
Florida, classifies ghost orchid data as sensitive and does not make 
those data publicly available. During peer and technical review of the 
ghost orchid SSA, numerous reviewers requested that we do not use 
location information and where possible, asked that we use more general 
descriptions of where ghost orchids are found to keep location 
information private. Identification and mapping of critical habitat is 
expected to increase the threat of take attributed to poaching because 
when we designate critical habitat, we publish detailed maps and 
descriptions of species' occurrences in the Federal Register, which in 
this case, could make the ghost orchid more vulnerable to poaching. 
Because we have determined that the designation of critical habitat 
will likely increase the degree of threat to the species, we find that 
designation of critical habitat is not prudent for the ghost orchid.

Required Determinations

Clarity of the Rule

    We are required by E.O.s 12866 and 12988 and by the Presidential 
Memorandum of June 1, 1998, to write all rules in plain language. This 
means that each rule we publish must:
    (1) Be logically organized;
    (2) Use the active voice to address readers directly;
    (3) Use clear language rather than jargon;
    (4) Be divided into short sections and sentences; and
    (5) Use lists and tables wherever possible.
    If you feel that we have not met these requirements, send us 
comments by one of the methods listed in ADDRESSES. To better help us 
revise the rule, your comments should be as specific as possible. For 
example, you should tell us the numbers of the sections or paragraphs 
that are unclearly written, which sections or sentences are too long, 
the sections where you feel lists or tables would be useful, etc.

Government-to-Government Relationship With Tribes

    In accordance with the President's memorandum of April 29, 1994 
(Government-to-Government Relations with Native American Tribal 
Governments; 59 FR 22951, May 4, 1994), E.O. 13175 (Consultation and 
Coordination with Indian Tribal Governments), the President's 
memorandum of November 30, 2022 (Uniform Standards for Tribal 
Consultation; 87 FR 74479, December 5, 2022), and the Department of the 
Interior's manual at 512 DM 2, we readily acknowledge our 
responsibility to communicate meaningfully with federally recognized 
Tribes and Alaska Native Corporations on a government-to-government 
basis. In accordance with Secretary's Order 3206 of June 5, 1997 
(American Indian Tribal Rights, Federal-Tribal Trust Responsibilities, 
and the Endangered Species Act), we readily acknowledge our 
responsibilities to work directly with Tribes in developing programs 
for healthy ecosystems, to acknowledge that Tribal lands are not 
subject to the same controls as Federal public lands, to remain 
sensitive to

[[Page 23883]]

Indian culture, and to make information available to Tribes. We sent 
letters to the Seminole Tribe and the Miccosukee Tribe, which are 
within the range of the ghost orchid. We will continue to work with 
relevant Tribal entities during the development of any final rules for 
the ghost orchid.
