Endangered and Threatened Wildlife and Plants; Removing Eastern
Puma (=Cougar) From the Federal List of Endangered and Threatened
Wildlife
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The best available scientific and commercial data indicate
that the eastern puma (=cougar) (Puma (=Felis) concolor couguar) is
extinct. Therefore, under the authority of the Endangered Species Act
of 1973, as amended, we, the U.S. Fish and Wildlife Service (Service),
propose to remove this subspecies from the Federal List of Endangered
and Threatened Wildlife. This proposed action is based on a thorough
review of all available information, which indicates that there is no
evidence of the existence of either an extant population or individuals
of the eastern puma and that, for various reasons, it is highly
unlikely that an eastern puma population could remain undetected over
the time span since the last confirmed sighting was documented in 1938.
DATES: We will accept comments received or postmarked on or before
August 17, 2015. Comments submitted electronically using the Federal
eRulemaking Portal (see ADDRESSES below) must be received by 11:59 p.m.
Eastern Time on the closing date. We must receive requests for public
hearings, in writing, at the address shown in FOR FURTHER INFORMATION
CONTACT by August 3, 2015. Informational webinars will be scheduled
upon request.

SUPPLEMENTARY INFORMATION:
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 effective as possible. Therefore, we invite tribal
and governmental agencies, the scientific community, and other
interested parties to submit comments and new data regarding this
proposed rule. In particular, we are seeking targeted information and
comments concerning the following:
(1) The persistence or extinction of a breeding population of the
eastern puma subspecies within its historical range;
(2) Verifiable reports or evidence of wild-origin pumas within the
historical range of the eastern puma subspecies;
(3) Our analysis of the status of the eastern puma; and
(4) The taxonomy of North American pumas.

scientific journal articles or other publications) to allow us to
verify any scientific or commercial information you include. Bear in
mind that comments simply advocating or opposing the proposed action
without providing supporting information will be noted but not
considered in making a determination, as section 4(b)(1)(A) of the
Endangered Species Act of 1973, as amended (16 U.S.C. 1531 et seq.)
(Act), directs that determinations as to whether any species is an
endangered species or threatened species shall be made ``solely on the
basis of the best scientific and commercial data available.''

final rule that differs from this proposal.
Public Hearing
Section 4(b)(5)(E) of the Act provides for one or more public
hearings on this proposal, if requested. We must receive requests for
public hearings, in writing, at the address shown in the FOR FURTHER
INFORMATION CONTACT section within 45 days after the date of this
Federal Register publication (see DATES). We will schedule public
hearings on this proposal, if any are requested, and announce the
dates, times, and places of those hearings, as well as how to obtain
reasonable accommodations, in the Federal Register at least 15 days
before the first hearing.
Peer Review
In accordance with our policy, ``Notice of Interagency Cooperative
Policy for Peer Review in Endangered Species Act Activities,'' which
was published on July 1, 1994 (59 FR 34270), we will seek the expert
opinion of at least three appropriate independent specialists regarding
scientific data and analyses contained in this proposed rule. We will
send copies of this proposed rule to peer reviewers immediately
following its publication in the Federal Register. The purpose of such
review is to ensure that our decisions are based on scientifically
sound data, assumptions, and analysis.
Background
This proposed rule is based on detailed information and indepth
analyses contained in the Service's 5-year review for the eastern puma
(USFWS 2011, entire), which can be accessed at: http://www.fws.gov/northeast/ECougar.
That review includes a thorough discussion of the
eastern puma's biology, historical records, and analysis of
contemporary sightings. We also take into account information that has
become available since 2011, noting that this information corroborates
the 5-year review's analysis. All references cited in the 2011 review
and this proposed rule are maintained on file at the Service's Maine
Field Office (see ADDRESSES).
Previous Federal Actions
Under the Act, we maintain a List of Endangered and Threatened
Wildlife (List) at 50 CFR 17.11 and a List of Endangered and Threatened
Plants at 50 CFR 17.12. On June 4, 1973 (38 FR 14678), we listed the
eastern puma (=cougar), Puma (=Felis) concolor couguar, as an
endangered subspecies (using the common name of eastern cougar). At
that time, critical habitat was not provided for under the Act;
consequently, critical habitat was not designated for the eastern
cougar. The principal factors leading to the listing of the eastern
puma were widespread persecution (poisoning, trapping, hunting, and
bounties), decline of forested habitat, and near-extirpation of white-
tailed deer populations during the 1800s, which together resulted in
the extirpation of most eastern puma populations by 1900.
A Service status review of the puma in North America, including the
eastern puma, was issued in 1976 (Nowak 1976). This review, along with
status reviews by some States and Canadian provinces (e.g., van Zyll de
Jong and van Ingen 1978, R.L. Downing newsletters from 1979 to 1982),
suggested that a large number of unverified public reports may be
evidence of a persisting, native breeding population of eastern pumas.
Such reports led the Service to retain the eastern puma on the List
until such time as either a breeding population or extinction could be
verified.
The Eastern Cougar Recovery Plan was approved in 1982 (USFWS 1982).
During plan preparation, R.L. Downing conducted field surveys and
investigated sighting reports and concluded that ``no breeding cougar
populations have been substantiated within the former range of F.c.
couguar since the 1920s.'' Nonetheless, the recovery plan states that
the eastern cougar could be reclassified from endangered to threatened
when one population containing at least 50 breeding adults was found or
established. It further states that the eastern cougar could be removed
from the List when at least three populations were found or
established, with each containing more than 50 breeding adults. Since
the plan's approval, no breeding populations have been found, nor have
any individual pumas known to be F.c. couguar (such individuals would
form the basis of a founder population). Thus, neither of the recovery
criteria was ever met.
Section 4(c)(2) of the Act requires that we conduct a review of
listed species at least once every 5 years to determine: (1) Whether a
species no longer meets the definition of an endangered species or
threatened species and should be removed from the List (i.e.,
delisted), (2) whether a species listed as endangered more properly
meets the definition of threatened and should be reclassified to
threatened (i.e., downlisted), or (3) whether a species listed as
threatened more properly meets the definition of endangered and should
be reclassified to endangered. In accordance with 50 CFR 424.11(d), we
will consider a species for delisting only if the best scientific and
commercial data substantiate that the species is neither endangered nor
threatened for one or more of the following reasons: (1) The species is
considered extinct, (2) the species is considered recovered, or (3) the
data available when the species was listed, or the interpretation of
such data, were in error.
Between 1979 and 1991, the eastern puma was included in three
cursory 5-year reviews conducted by the Service: A 1979 review of all
domestic and foreign species listed prior to 1975 (44 FR 29566, May 21,
1979), a 1985 review of all species listed before 1976 and from 1979 to
1980 (50 FR 29901, July 22, 1985), and a 1991 review of all species
listed before 1991 (56 FR 56882, November 6, 1991). None of these
reviews recommended a change from the eastern puma's listing
classification as endangered.
On January 29, 2007, we published a Federal Register notice
announcing a 5-year review specific to the eastern puma and nine other
species, and we requested information from the public concerning the
eastern puma (72 FR 4018). The assessment of the eastern puma's current
status, completed on January 28, 2011 (USFWS 2011), found no evidence
of the existence of either an extant population or individual eastern
pumas, and concluded, therefore, the subspecies should be considered
extinct. The assessment thus concluded that the eastern puma does not
meet the definition of either an endangered species or a threatened
species under section 3 of the Act.
Assessment of Species Status
Section 4 of the Act and its implementing regulations (50 CFR part
424) set forth the procedures for listing species, reclassifying
species, and removing species from listed status.
[[Page 34597]]
``Species'' is defined by the Act as including any species or
subspecies of fish or wildlife or plants, and any distinct population
segment of any species of vertebrate fish or wildlife which interbreeds
when mature (16 U.S.C. 1532(16)). To determine whether a species should
be listed as endangered or threatened, we assess the likelihood of its
continued existence based on the five factors described in section
4(a)(1) of the Act (see Consideration of Factors Under Section 4(a)(1)
of the Act). A species may be reclassified or removed from the List on
the same basis. With regard to delisting a species due to extinction,
``a sufficient period of time must be allowed before delisting to
indicate clearly that the species is extinct'' (50 CFR 424.11(d)(1)).
According to these standards, we must determine whether the eastern
puma is a valid subspecies and whether the subspecies is still extant
in order to determine its appropriate listing status. The following
sections thus examine the biological and legal information considered
to be most germane to the status of the eastern puma as a valid, extant
subspecies before looking at factors that may affect the its continued
existence.
Overview
The eastern puma (Puma (=Felis) concolor couguar) is treated as a
subspecies of the puma. The species is also known by many other common
names, including, among others, cougar, catamount, mountain lion,
panther, painter, and wildcat. As explained in the 5-year review (USFWS
2011, pp. 4-5), the puma is the most widely distributed land mammal in
the New World and is one of the most adaptable mammals in the northern
hemisphere. At the time of European contact, the puma occurred
throughout most of South, Central, and North America. In North America,
breeding populations still occupy about one-third of their historical
range but are now absent from central and eastern North America outside
Florida. The puma is documented historically from eastern North America
to about 45 degrees north latitude (roughly equating to the colonial-
era range of its primary ungulate prey, white-tailed deer) in a variety
of habitats from swamps and everglades in the Southeast to temperate
forests in the Northeast. Aside from presence reports, few historical
records exist regarding the natural history of the eastern puma.
Current Legal Status
The eastern puma is one of three subspecies of puma that are
federally listed as endangered species under the Act; the others are
the Florida panther (Puma (=Felis) concolor coryi), listed in 1967 (32
FR 4001, March 11, 1967), and the Costa Rican puma (Puma (=Felis)
concolor costaricensis), listed in 1976 (41 FR 24062, June 14, 1976).
Both the Florida panther and Costa Rican puma remain extant, albeit
extremely rare.
In Canada, the first status review of the eastern puma by the
Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in
1978 assigned endangered status to the taxon Puma concolor couguar
based on puma reports in Ontario, Quebec, and the Maritimes provinces.
In 1998, the Canadian eastern puma listing was changed from the
Endangered to the Data Deficient or Indeterminate category for Ontario,
Quebec, New Brunswick, and Nova Scotia.
The eastern cougar (=puma) is listed as endangered in the
International Union for Conservation of Nature's (IUCN) Mammal Red Data
Book (IUCN 1982). The subspecies is also classified as an Appendix I
animal under the Convention on International Trade in Endangered
Species of Wild Fauna and Flora (CITES), which provides protection from
international trade.
Legal protections at the State and provincial levels are discussed
under ``Historical Range, Abundance, and Distribution'' below.
Biological Status
Taxonomy and Genetics: The eastern puma 5-year review (USFWS 2011,
pp. 29-35) provides a full discussion of the taxonomic history of this
subspecies. As indicated in that review, the current practice is to
refer to the species as Puma concolor (Linnaeus 1771) and the eastern
subspecies as Puma concolor couguar.
There is ongoing debate about the taxonomic assignment of puma
subspecies, including the question as to whether North American pumas
comprise a single subspecies or multiple subspecies. In particular,
there has been disagreement about whether the scientific community
should accept the use of genetics as the driving factor in puma
taxonomy, as was done by Culver et al. (2000, entire). The Service's
position is that until a comprehensive evaluation of the subspecies
status of North American pumas, including genetic, morphometric, and
behavioral analyses, is completed, the best available information
continues to support the assignment of the eastern taxon to Puma
concolor couguar as distinct from other North American subspecies.
In recognizing the eastern puma as a valid subspecies, and thus a
valid listed entity, we next evaluate whether the subspecies should be
determined extinct. It is important to note that assessing the
biological status of the eastern puma as a subspecies does not preclude
eventual taxonomic revision.
Biology and Life History: There is little basis for believing that
the ecology of eastern pumas was significantly different from puma
ecology elsewhere on the continent. Our biological understanding of the
eastern puma, therefore, is derived from studies conducted in various
regions of North America and, to the extent possible, from eastern puma
historical records and museum specimens. This information is detailed
in the status review (USFWS 2011) on pages 6 through 8.
Historical Range, Abundance, and Distribution: Details and
citations for the following summary are provided in the status review
(USFWS 2011, pp. 8-29 and 36-56). Although a lack of reliable sightings
and historical records makes it difficult to estimate past abundance
and distribution, the available information is discussed below.
In eastern North America at the time of European contact, the puma
ranged from Florida to southern Quebec and remained abundant through
much of eastern North America during the colonial era. Despite its
apparent early abundance, however, only 26 historical specimens of
eastern pumas, from seven eastern States and one Canadian province
within the subspecies' historical range, reside in museums or other
collections.
Based on this admittedly small number of specimens and other scant
evidence, Young and Goldman (1946) described the historical range of
Felis concolor couguar as southeastern Ontario, southern Quebec, and
New Brunswick in Canada, and a region bounded from Maine to Michigan,
Illinois, Kentucky, and South Carolina in the eastern United States.
The Service's recovery plan for the eastern cougar describes a similar
range (USFWS 1982, pp. 1-2), although the range is mapped a little
farther north into Ontario. The recovery plan also maps Felis concolor
schorgerii, named as a subspecies after Young and Goldman (1946) was
published, to the west and F.c. coryi to the south of the eastern
puma's range.
The most recently published assessment of the puma in eastern
Canada, conducted by the Committee on the Status of Endangered Wildlife
in Canada (COSEWIC) (Scott 1998), maps
[[Page 34598]]
the puma's range throughout southern Ontario and Manitoba. The eastern
subspecies is not stipulated in Scott's (1998) range description;
indeed, the review questioned whether the eastern puma was ever a valid
subspecies. Other authors have also discussed the past distribution of
pumas in Canada without acknowledging them as the eastern subspecies.
Rosette (2011) asserts that native, free-roaming pumas of unknown
origin may continue to survive in Ontario while conceding that no
evidence of their presence has been documented for almost 100 years. In
Manitoba, on the other hand, several authors have documented a
relatively consistent record of pumas, but there is no evidence that
these are eastern pumas or that the subspecies ever occurred that far
west.
The historical literature indicates that puma populations were
thought to have been largely extirpated in eastern North America
(except for Florida and perhaps the Smoky Mountains) by the 1870s, and
in the Midwest by 1900. According to many historical accounts, pumas
were greatly feared and were also persecuted as competitors for game
and occasional predators of livestock. Eastern puma populations also
decreased as habitat conditions for the puma's primary prey base,
white-tailed deer, changed dramatically during this time. By the mid-
to late-1800s, human settlement patterns resulted in the extirpation of
deer from much of eastern North America. The last records of pumas in
most of the eastern States and provinces, from approximately 1790 to
1890, coincided with loss of deer populations and habitat.
By 1929, eastern pumas were believed to be ``virtually extinct,''
and Young and Goldman (1946) concurred that ``they became extinct many
years ago.'' On the other hand, puma records from New Brunswick in 1932
and Maine in 1938 suggest that a population may have persisted in
northernmost New England and eastern Canada.
In the Service's 1976 status review (Nowak 1976), R.M. Nowak stated
his belief that the large number of unverified sightings of pumas
constituted evidence that certain other populations had also survived
or had become reestablished in the central and eastern parts of the
continent and may have increased in number since the 1940s. Further, as
stated in the Eastern Cougar Recovery Plan (USFWS 1982, pp. 4, 7), R.L.
Downing believed it possible that a small population may have persisted
in the southern Appalachians into the 1920s. Nonetheless, the field
surveys he conducted and the reports he investigated prior to writing
the recovery plan led him to conclude that ``no breeding cougar
populations have been substantiated within the former range of F. c.
couguar since the 1920s'' (USFWS 1982, p. 6). Scott's (1998) COSEWIC
review also concluded that ``there is no objective evidence (actual
cougar specimens or other unequivocal confirmation) for the continuous
presence of cougars since the last century anywhere in eastern Canada
or the eastern United States outside of Florida,'' and that ``there is
circumstantial evidence for virtual or complete extirpation'' from
central Ontario eastward.
The known status of the eastern puma within its historical range is
summarized in table 1, below. A more detailed discussion of the
historical status, current confirmed and unconfirmed puma sightings,
potential habitat, and legal protection (also see Current Legal Status
above) of the eastern puma in the states and provinces is provided in
the 5-year status review (USFWS 2011, pp. 8-26). To summarize, eastern
pumas historically were considered generally common and widespread;
however, by the late 1800s, eastern pumas were believed to be
extirpated from most of their range. As indicated in table 1, the
majority of the most recent confirmed reports date from the mid-1800s
to around 1930. Later reports are thought to be indicative of
dispersers of western pumas, as in Missouri, or released animals, as in
Newfoundland. Although there now appears to be adequate habitat and
prey for pumas in various portions of the subspecies' historical range,
the many decades of habitat loss and near-extirpation of the puma's
primary prey, white-tailed deer, bring into question the continued
survival and reproduction of eastern pumas over that time.

Current Biological Status of Pumas in Eastern North America: Our
conclusions regarding the current biological status of the eastern puma
rely upon three lines of evidence: (1) The detectability of wild pumas,
(2) contemporary accounts of puma sightings in eastern North America as
evidence of the continued existence of eastern pumas, and (3) the time
since the last verified eastern puma occurrence. Recognizing that
extinction cannot be demonstrated with absolute certainty (i.e., it is
a probabilistic determination), the totality of evidence for the
eastern puma provides a basis for drawing robust conclusions about the
true status of this subspecies, as discussed below. A more detailed
discussion and references are provided in the 5-year status review
(USFWS 2011, pp. 36-56).
Detectability of pumas: This line of evidence addresses the
question of how likely it is that eastern puma individuals or
populations could continue to persist without being detected. If
entities are difficult to detect, lack of confirmed sightings may not
be indicative of absence; however, if detectability is known to be
high, it is much more likely that lack of sightings is evidence of
absence. For the eastern puma, detectability differs between
individuals and populations. Although individual pumas are difficult to
detect, determining the presence of a puma population is possible with
a reasonable amount of effort.
Detection of single, transient pumas is particularly problematic
because they cover such a large range and leave behind little sign of
their occupation (e.g., scrapes, kills, and tracks) in any one place.
The best prospect for detecting these animals is through tracks left
during their extensive daily movement in the snowy regions of North
America.
Numerous searches and surveys have been undertaken to detect the
presence of individual pumas, either directly or as part of large
carnivore studies, and, by extension, puma populations in eastern North
America. Searches have been conducted in areas reputed to harbor pumas,
and reports of puma sightings have been investigated
[[Page 34601]]
extensively. Surveys have utilized a variety of techniques, including
trail transects with motion-sensing cameras, hair trap posts and
rubbing pads, and snow-covered road surveys to detect the tracks or
signs of pumas.
Such studies have yielded few positive results in eastern North
America. However, in other parts of North America, pumas have been
readily detected through searches and surveys. Additionally, pumas have
been detected as a result of road kills; even in areas with small
extant populations (such as Florida and South Dakota) and low road
densities, pumas killed on roads are reported nearly every month of the
year. In contrast, although road mortalities have been documented in
the eastern United States and Canada in recent years, the reports are
irregular, and in the rare instances where individuals have been
verified as wild pumas, they have originated outside the eastern puma's
historical range.
Overall, pumas have been readily detectable in areas of North
America outside the historical range of the eastern puma. We can thus
conclude that pumas and, in particular, puma populations, could be
detected with a reasonable amount of effort if present in eastern North
America. We further conclude that the searches, surveys, and efforts to
verify sightings by the public since the 1950s constitute a reasonable
effort, as discussed below and detailed in the 5-year review (USFWS
2011, pp. 26-29). However, despite the detectability of pumas, no
evidence has been presented to verify the continued existence of the
eastern subspecies or of any breeding population of pumas within its
historical range.
Contemporary accounts of pumas in eastern North America as evidence
of the continuing existence of the subspecies: As discussed in the 5-
year review (USFWS 2011, pp. 36-38), renewed interest in puma
conservation over the past 60 years has resulted not only in a
profusion of reported sightings by the public but also efforts by
scientists to determine the presence of pumas in eastern North America.
We summarize these accounts below and discuss whether they constitute a
basis for concluding that the eastern puma remains extant.
There were few reports of pumas in eastern North America between
the late 1800s and the 1940s and 1950s (see ``Historical Range,
Abundance, and Distribution'' above). The number of reports increased
in the 1950s, and states, provinces, and puma organizations began
maintaining databases of puma sightings. The increased reporting
coincided with coverage in the popular press and assertions by
biologists and other writers that there was sufficient evidence to
believe that the eastern puma still existed. It also coincided with a
growing number of pumas in the North American pet trade.
A surge in reported sightings followed in the 1960s and 1970s,
again coincident with publications claiming that a relic population of
pumas from the northeastern United States and eastern Canada was
repopulating eastern North America. Although based mostly on
questionable evidence, many--including wildlife biologists--accepted
this hypothesis without critical scientific review.
The sheer volume of anecdotal reports was cited as evidence for the
continued existence of pumas, although few of these reports were ever
substantiated. By the 1970s, puma advocacy groups had been established,
and they, along with many independent researchers and advocates, were
investigating sightings and promoting puma recovery. This led to the
1973 listing of the eastern cougar, even though there was no physical
evidence showing that populations existed at that time.
Since listing, thousands of reports have been collected by wildlife
agencies and puma organizations, including hundreds of puma sightings
by reliable witnesses where physical evidence was not available. Most
recently, during preparation of the eastern puma 5-year review (from
2007 to 2010), 60 reports of pumas were considered to have some
likelihood of validity based on verified identification of tracks;
photographic evidence; genetic, hair, or scat samples; or discovery of
carcasses (USFWS 2011, appendix B). It is important to note that none
of these reports was verified as the eastern subspecies.
A number of formal studies have been undertaken to determine the
presence of pumas in eastern North America. One study (Michigan
Wildlife Conservancy 2003) detected pumas, but the results and
methodology were subsequently contested. Elsewhere in the Midwest,
pumas have been detected with trail cameras. A puma sighted in
Wisconsin was verified in January 2008 and shot in Chicago, Illinois,
in April 2008. This animal was determined to be of North American
origin with characteristics similar to South Dakota pumas. In 2009,
another Wisconsin puma was treed and photographed on several occasions;
DNA analysis was not available for this animal. In eastern Canada, a
survey of the Maritime provinces from 2001 to 2004 (Gauthier et al.
2005, entire) confirmed six samples as puma. Of these six samples,
several were found to be of South American origin, indicating that
released or escaped captive pumas are also present in the wild, while
others were verified as North American genotypes without being able to
determine if they were of captive or wild origin.
Overall, most of the surveys conducted by wildlife biologists in
eastern North America--some of which have targeted pumas while others
have targeted different species (e.g., wolves, lynx)-- have failed to
detect any sign or evidence of the presence of pumas. Details of each
survey effort are provided in the eastern puma 5-year review (USFWS
2011, pp. 26-29 and appendix B).
Many puma sightings are reported as ``eyewitness'' accounts; this
type of report has increased with the availability of Internet search
engines and is sometimes spurred by news articles that encourage others
to report observations. The reliability of such accounts can depend on
time of day, experience level of the observer, duration of the
observation, and observer trustworthiness. Insufficient field
identification and tracking skills, as well as photographs of single
tracks rather than a series of tracks, may further compromise
reliability. Based on our assessment of puma eyewitness accounts (USFWS
2011, pp. 36-42), it appears that 90 to 95 percent of puma sightings
and vocalizations reported by the public involve instances of
misidentification and, at times, deliberate hoaxes.
Although documention of sightings by the public in areas where
pumas are uncommon can be useful--particularly where protocols for puma
sightings and analysis have been established--compilations of
unconfirmed sighting reports can also produce a large volume of cogent
but misleading information. The problem with treating anecdotal
sightings as empirical evidence is compounded when such observations
are supplemented by inconclusive physical evidence such as indistinct
photographs. Typically, as a species becomes rarer, the proportion of
false positives increases; thus, even the most tangible evidence of a
puma must be followed by further inquiry to identify it as a wild
specimen and ascertain its origins.
Over the past 50 years, thousands of puma sightings have been
investigated, at substantial public and private expense. Only a small
percentage of investigations have resulted in collection of evidence
that could be interpreted or further analyzed, and only a small
percentage of the analyses have provided irrefutable proof of a
[[Page 34602]]
wild puma. The most recent case was a male puma killed on a highway in
Milford, Connecticut, in 2011. Genetic analysis of the animal
determined that its origin was a population in South Dakota, indicating
that it was a transient western puma; the same animal had been
documented in Minnesota, Wisconsin, and northern New York prior to
arriving in Connecticut.
Despite the large number of contemporary eastern puma accounts, few
of the surveys and investigations of puma reports have provided
verifiable evidence of the presence of pumas, irrespective of origin,
in eastern North America, and even fewer have provided irrefutable
proof of a wild puma. Nonetheless, verified puma occurrences have
occurred with enough frequency in eastern North America (approximately
15 puma carcasses have been documented in eastern North America north
of Florida since 1950) to encourage a widespread belief that a cryptic
eastern puma population continues to persist.
In considering whether all this constitutes evidence of an extant
eastern puma population, three possible hypotheses have been
considered: First, that the observed animals are members of a
persistent relic population; second, that they are released or escaped
captives; or, third, that they are dispersers from source populations
outside of the region. These hypotheses are discussed, in turn, below.
1. A relic population of pumas has survived in eastern North
America. Although some hypothesize that the eastern puma has survived
in eastern North America since colonial times, the continued existence
of a puma population in eastern North America is not corroborated by
the historical record, the history of white-tailed deer, or our current
understanding of puma ecology (USFWS 2011, pp. 43-46).
As noted above, most eastern pumas were thought to have been
virtually extirpated by the late 1800s. Had members of the subspecies
survived, they should have been detectable. With some exceptions (e.g.,
later records in Maine and New Brunswick) authors document a near-
absence of records from the late 1800s to the 1950s. Further, despite
the verified reports of pumas mentioned above, whenever we have been
able to determine the origins of these pumas, they have been shown to
be either captive pumas (generally South American pumas or their
progeny) or dispersers from western populations. None of these animals
has been confirmed as the eastern subspecies.
A number of population viability analyses indicate that both a
minimum population size and minimum area of high-quality habitat are
needed for long-term puma persistence. The probability of population
persistence also depends on favorable demographic factors. Studies to
date indicate, very approximately, that puma populations consisting of
fewer than 15 to 20 animals and occupying less than 386 to 772 mi\2\
(1,000 to 2,000 km\2\) of high-quality habitat would be unlikely to
persist over the long term, particularly in the face of any adverse
genetic effects (USFWS 2011, pp. 8 and 46). Effects of postsettlement
persecution of eastern pumas, compounded by loss of habitat and the
near-extirpation of white-tailed deer, severely reduced the probability
of persistence using both of these measures. Pumas likely survived
longest in remaining large forest tracts where deer were not extirpated
and at the northern periphery of their historical range as deer shifted
northward (which would explain the later puma records in Maine and New
Brunswick). To survive elsewhere in the East, puma populations would
have had to persist for decades with extremely low or absent
populations of their primary prey, and such persistence is doubtful.
Even in northern regions, deer populations were greatly reduced, and
snow depths there would have been limiting for pumas.
This information, along with the total absence of verified
contemporary eastern puma records, suggests that a remnant population
of eastern pumas is highly unlikely to have survived two centuries of
intense human exploitation and persecution, habitat changes, and near-
eradication of its primary prey. Further, were a relic puma population
to have survived, the rebounding of deer populations along with
protections from take under the Act would have likely resulted in a
corresponding increase in documentation of eastern puma presence and
increased likelihood of deterction. Given the lack of verified
contemporary records, we therefore find no evidence to support the
hypothesis that an undetected relic population of eastern pumas remains
extant.
2. Pumas occurring in eastern North America are released or escaped
pets. Since the mid-1900s, there has been speculation that perhaps all
pumas observed in eastern North America (outside of Florida) are
escaped or released captive animals. The findings regarding this
hypothesis, presented in the 5-year review (USFWS 2011) on pp. 47-51
and in Appendix B, are summarized below.
Genetic techniques are now available to determine if puma specimens
are of North American origin and therefore more likely to be wild
animals. Captive puma enthusiasts apparently favor Central and South
American animals, and it can be assumed that pumas found in eastern
North America with South American DNA are escaped or released captives
or their progeny. Since the early 1990s, 24 puma genetic samples have
been collected within the historic range of the eastern puma and tested
using a variety of techniques (USFWS 2011, Appendix B). Of these, about
one-third were found to be of Central or South American origin, one-
third were of North American origin, and one-third were identified as
pumas but of unknown origin.
In addition to genetic evidence, the increasing frequency of
reported puma sightings in the eastern United States and Canada
correlates with the increased private ownership, trade, and breeding of
pumas that began in the 1940s and 1950s. Zoos formerly sold or gave
pumas to individuals or dealers, although this is strictly prohibited
today and there currently is a ban on breeding pumas in zoos. More
recently, Internet sales of exotic cats have flourished, illustrating
the continuing ease of acquiring captive pumas. This situation is
exacerbated in some States by enforcement challenges, and these States'
lack of information about the number and disposition of captive pumas
within their borders. Overall, there are likely thousands of privately-
held (both legally and illegally) pumas in the eastern United States,
dwarfing the number of pumas in zoos.
Released or escaped pumas are documented in numerous accounts,
along with frequent reports of such pumas being recaptured (USFWS 2011,
pp. 49-50). It has also been found that individual captive pumas may
successfully adapt to conducive conditions in the wild. If released or
escaped captives initially avoid recapture or death, they most likely
become wandering transients. Overall, it may be possible, although
unlikely, for individual captive pumas to transition into a wild
existence, establish home ranges, and, like other transient pumas,
persist with low detectability.
Nonetheless, the likelihood of escaped or released captive pumas
establishing breeding populations is minimal, both because transient
pumas are unlikely to recolonize new areas unless there is an adjacent
resident puma population, and because their survival prospects are
generally low. The multiple reports we have received of pumas in a
geographic location over a period of months (but not years) could
constitute actual observations of
[[Page 34603]]
escaped animals. However, if these animals are declawed or defanged,
they have little chance of surviving over the long term, particularly
at rates needed to establish a population. Further, few of the many
reported sightings of puma kittens in eastern North America, which
would be indicative of a breeding population, have been substantiated
(USFWS 2011, p. 51).
We conclude that the evidence supports the hypothesis that pumas
recently found in eastern North America are released or escaped captive
animals, with the exception of some animals in Illinois, Wisconsin, and
other midwestern States that are dispersing from more westward
populations (see discussion below). Genetic and isotope techniques are
improving, which will help distinguish whether pumas of North American
ancestry are of wild or captive origin.
3. Pumas in eastern North America are dispersers from breeding
populations to the west and south. Breeding puma populations in
proximity to the eastern puma's historical range occur in Manitoba,
North Dakota, South Dakota, possibly Nebraska and Oklahoma, and
Florida. The Service's 5-year review discusses the likelihood of
immigration of pumas to eastern North America from these populations
(USFWS 2011, pp. 51-56).
Regarding dispersal from Florida, there was little evidence until
recently that the Florida panther population was expanding northward,
but since 1998, four tagged and several unmarked animals have crossed
the Caloosahatchee River, previously thought to be a barrier to
northward expansion. In addition, an adult male puma killed in Georgia
in 2008 originated in Florida. Nonetheless, given the many other
substantial barriers to dispersal, it is considered highly unlikely
that Florida panthers are dispersing out of Florida with enough
frequency to establish populations elsewhere in the Southeast, although
adequate prey and habitat are available in Georgia.
As to dispersal from the West, puma populations in most western
States are believed to be at historically high levels, and breeding
populations have expanded their ranges eastward. Dispersing pumas have
been reported since 1990 in the Midwest, primarily west of the
Mississippi River and possibly the Great Lakes Region, with over 130
confirmed puma records documented in Wisconsin, Illinois, Nebraska,
Kansas, Minnesota, Missouri, and Iowa.
These records confirm that eastward dispersal from breeding
populations of western pumas is occurring, especially from North and
South Dakota (note the previous mention of a South Dakota puma killed
in Connecticut in 2011). Confirmed records of wild-origin pumas exist
in many States and provinces bordering the western and northern
peripheries of the eastern puma's historical range, and most States in
the Midwest now acknowledge the presence of wild pumas. Further,
persistent puma presence has been documented in a few areas (Missouri,
Iowa, Minnesota, Nebraska), suggesting that individual pumas are
successfully surviving in the wild and may have established home
ranges.
Suitable, albeit sometimes fragmented, habitat and an adequate prey
base are available for pumas in the Midwest and Great Lakes regions,
with large populations of white-tailed deer occurring throughout the
region. Moreover, numerous dispersal corridors leading to highly
suitable habitat areas in the Midwest have been identified within
feasible dispersal distances for pumas. Although dispersing pumas
frequently travel along deer-rich riparian corridors and generally
avoid human-dominated landscapes, pumas are known to disperse across
large expanses of inhospitable habitat. Roads and railroad rights-of-
way and associated brush belts also provide dispersal corridors. The
upper Midwest Region is the most favorable route for cougars
repopulating the East from the Dakotas, and Manitoba's puma population
may be a potential source for animals observed in Ontario, northern
Minnesota, Wisconsin, and Michigan.
Although individual males are known to disperse over long
distances, the establishment of puma populations in the Midwest and
Great Lakes regions is less likely to occur unless breeding range
expansion is facilitated. Female pumas do not move far from their natal
areas, and male pumas compete for access to females; that is, in
addition to adequate food and cover, dispersing males search for areas
occupied by one or more resident females. Thus, range expansion is
unlikely unless females disperse--or are released--into new habitats.
As would be expected, most of the recent Midwest puma records are of
males.
Given evidence of growing puma populations in the West, increased
dispersal, and availability of dispersal corridors and prey in the
Midwest, we conclude that wild-origin pumas (primarily males) will
continue to disperse into the midwestern States and into the historical
range of the eastern puma and are the likely source of any wild pumas
that currently exist in eastern North America.
Summary: First, it is important to note that the alternative
hypotheses for the continuing presence of pumas in eastern North
America are not mutually exclusive. Physical evidence indicates that
pumas recently found in eastern North America are released or escaped
captive animals, with the exception of some wild animals in the Midwest
(and one documented in Connecticut) that are dispersing from western
populations. The evidence also suggests that these are transient pumas
with little potential for naturally establishing breeding populations.
Most significantly, no evidence whatsoever has been found to show
that either individual eastern pumas or any relic populations of the
eastern puma subspecies remain extant in eastern North America.
Time since last verified eastern puma report: The most recently
confirmed records of pumas native to eastern North America are from
Tennessee (1930), New Brunswick (1932), and Maine (1938). These records
coincide with the extirpation of white-tailed deer in most of its range
in the 1800s, with the exception of some remaining large forest tracts,
and a shift toward the northern periphery of its historical range
during that time. Reports of pumas were made by reputable observers in
Missouri as late as 1966, but the taxonomy of these animals has long
been in question.
It is notable that areas in eastern North America that still
support extant populations of native pumas (e.g., Florida and Manitoba)
have had a long and continuous record of confirmed occurrences. In
contrast, a long-term record of verified puma occurrences is lacking in
regions of eastern North America outside Florida.
Given the puma's life span, generally thought to be 10 to 11 years,
it is extremely implausible that non-breeding eastern pumas could have
persisted in the wild under conditions of habitat loss and lack of
their primary prey base and without being detected for over six
decades. It is equally if not more unlikely that breeding populations
of the subspecies could have gone undetected for that long. Based on
how improbable it is that eastern puma individuals or populations could
have weathered such a long period of habitat and prey loss, along with
the lack of either a recent report or a long-term record of eastern
puma occurrences, we conclude that the time since the last verified
eastern puma record is indicative of the long-term absence of this
subspecies.
[[Page 34604]]
Summary: Overall, we find that pumas (except for single transients)
are reasonably detectable, that no contemporary puma sightings in
eastern North America have been verified as the eastern puma subspecies
since 1938, and that it is extremely unlikely that either individuals
or eastern puma populations could have survived the long period during
which most of their habitat was lost and their primary prey base was
nearly extirpated. We therefore determine the eastern puma subspecies
to be extinct.
Consideration of Factors Under Section 4(a)(1) of the Act
As mentioned under Assessment of Species Status above, section 4 of
the Act and its implementing regulations (50 CFR part 424) set forth
the procedures for listing, reclassifying, or removing species from
listed status. When we evaluate whether a species should be listed as
an endangered species or threatened species, we must consider the five
listing factors described in section 4(a)(1) of the Act: (A) The
present or threatened destruction, modification, or curtailment of the
species' habitat or range; (B) overutilization for commercial,
recreational, scientific, or educational purposes; (C) disease or
predation; (D) the inadequacy of existing regulatory mechanisms; and
(E) other natural or manmade factors affecting the species' continued
existence. We must consider these same factors in reclassifying a
species or removing it from the List.
The principal factors leading to the listing of the eastern puma
were widespread persecution (poisoning, trapping, hunting, and
bounties), decline of forested habitat, and near-extirpation of white-
tailed deer populations during the 1800s. These impacts led to the
extirpation of most eastern puma populations by 1900.
However, because we have determined that all populations of pumas
described as the eastern puma, Puma (=Felis) concolor couguar, have
been extirpated, analysis of the five factors under section 4(a)(1) of
the Act, which apply to threats facing extant species, is tragically
irrelevant. As stated above, given the period of time that has passed
without verification of even a single eastern puma, the Service
believes that the last remaining members of this subspecies perished
decades ago. Therefore, the eastern puma is no longer extant and
logically can no longer be an endangered species or threatened species
because of any of the five factors.
Conclusion
Widespread persecution, decline of forested habitat, and near-
extirpation of white-tailed deer populations during the 1800s led to
the loss of most eastern puma populations by 1900. Although individual
pumas were taken as late as 1932 in New Brunswick and 1938 in Maine,
neither the Service's 5-year status review (USFWS 2011) nor information
that has become available since then has yielded any convincing
evidence to support the hypothesis that small, cryptic populations of
the subspecies continue to persist anywhere within its historical
range, including northern New England and eastern Canada. These
findings are supported by the most recent Canadian Wildlife Service
status review (Scott 1998) and by analyses in the revised Florida
Panther Recovery Plan (USFWS 2008). We therefore conclude that the
subspecies Puma (=Felis) concolor couguar, or eastern puma (=cougar),
was likely extirpated from eastern North America prior to its listing
in 1973, noting, however, that extirpation had not been substantiated
at that time.
We further conclude that although there have been thousands of puma
sightings in eastern North America since the 1950s, most are a case of
mistaken identity. We acknowledge that a small number of pumas are
occasionally encountered in the wild in eastern North America within
the historical range of the listed eastern puma. Based on the best
available scientific evidence, however, we conclude that these are
escaped or released captive animals, or dispersers from western puma
populations, not the eastern puma subspecies. Breeding of escaped or
released individuals, if it occurs, appears to be an extremely rare
event, and there is no evidence of any population established from
escaped or released captive animals.
Although it is improbable that pumas can disperse regularly out of
Florida, puma range expansion may be occurring in the Midwest from the
West. Several wild-origin pumas have been confirmed in that region and
are likely dispersers from western populations that have reached
carrying capacity. Dispersal into the Midwest will likely increase in
frequency as long as western puma populations continue to grow.
With regard to puma taxonomy, we recognize the ongoing debate among
scientists about the taxonomic assignment of puma subspecies and
whether genetics should be the driving factor in puma taxonomy.
Although Culver et al.'s (2000, entire) genetic analysis injected
significant uncertainties into current puma taxonomy, we have concluded
that until a comprehensive evaluation (including genetic, morphometric,
and behavioral analyses) of North American pumas is completed, the best
available information continues to support the assignment of the
eastern taxon to Puma (=Felis) concolor couguar. We further note that
these taxonomic questions do not affect the determinations in this
proposed rule regarding the listed entity's biological status.
Taking all these considerations into account, we conclude that the
taxon Puma (=Felis) concolor couguar is extinct.
Proposed Determination
After a thorough review of all available information, we have
determined that the subspecies Puma (=Felis) concolor couguar is
extinct. Based upon this determination and taking into consideration
the definitions of ``endangered species'' and ``threatened species''
contained in the Act and the reasons for delisting as specified in 50
CFR 424.11(d), we propose to remove the eastern puma from the List of
Endangered and Threatened Wildlife at 50 CFR 17.11.
Available Conservation Measures
Conservation measures provided to species listed as endangered or
threatened under the Act include recognition, recovery actions,
requirements for Federal protection, and prohibitions against certain
practices. However, since the Service has determined the eastern cougar
to be extinct, this proposed rule, if made final, would remove any
Federal conservation measures for any individual pumas (except
dispersing Florida panthers) that may subsequently be found within the
historical range of the eastern puma.
Effects of the Rule
This proposal, if made final, would revise 50 CFR 17.11 to remove
the eastern puma from the List of Endangered and Threatened Wildlife
due to extinction. The prohibitions and conservation measures provided
by the Act would no longer apply to this subspecies. There is no
designated critical habitat for the eastern puma.
Post-Delisting Monitoring
Section 4(g)(1) of the Act, added in the 1988 reauthorization,
requires us to implement a program, in cooperation with the States, to
monitor for not less than 5 years the status of all species that have
recovered and been removed from the Lists of Endangered and Threatened
[[Page 34605]]
Wildlife and Plants (50 CFR 17.11 and 17.12). Based upon the results of
more than 25 years of investigating sporadic reports of sightings and
our conclusion that the eastern puma is extinct, post-delisting
monitoring is not warranted.
Required Determinations
Clarity of the Rule
We are required by Executive Orders 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:
(a) Be logically organized;
(b) Use the active voice to address readers directly;
(c) Use clear language rather than jargon;
(d) Be divided into short sections and sentences; and
(e) 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 names 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.
National Environmental Policy Act
We have determined that an environmental assessment or an
environmental impact statement, as defined under the authority of the
National Environmental Policy Act of 1969, need not be prepared in
connection with regulations adopted pursuant to section 4(a) of the
Act. We published a notice outlining our reasons for this determination
in the Federal Register on October 25, 1983 (48 FR 49244).
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), E.O. 13175, and the Department of the
Interior's manual at 512 DM 2, we readily acknowledge our
responsibility to communicate meaningfully with recognized Federal
Tribes on a government-to-government basis. In accordance with
Secretarial 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 Indian culture, and to make
information available to Tribes. Accordingly, the Service communicated
with Tribes during the 5-year review process, and we are notifying
Tribes of our activities regarding this proposal to delist the eastern
puma based on extinction.
