Federal Register / Vol. 74, No. 50 / Tuesday, March 17, 2009 / Rules and Regulations
FR 2895). The effective date of the rule
was originally March 17, 2009, with a
compliance date of July 15, 2009.
In accordance with the January 20,
2009 memorandum, 74 FR 4435,
January 26, 2009, from the Assistant to
the President and Chief of Staff, on
March 2, 2009 (74 FR 9172), FMCSA
sought comment on a proposal to extend
the effective date of the final rule for 90
days. FMCSA received five comments to
the March 2 notice. All of the
commenters supported extending the
effective date of the final rule for 90
days, providing for a new comment
period, and, if appropriate,
reconsidering the final rule based on
any new information provided by the
comments. Therefore, FMCSA extends
the effective date of its January 16, 2009,
final rule from March 17, 2009, to June
15, 2009. This will provide us sufficient
time to address issues that have been
raised about whether the new rule will
make it more difficult for us to enforce
our requirements concerning safety and
access for individuals with disabilities.
Although we believe the final rule fully
addressed these issues, in light of the
Assistant to the President and Chief of
Staff’s memorandum, we are delaying
the effective date of the final rule to
allow the Agency the opportunity for
further review and consideration of
these issues.

Endangered and Threatened Wildlife
and Plants; Listing Phyllostegia
hispida (No Common Name) as
Endangered Throughout Its Range
AGENCY: Fish and Wildlife Service,
Interior.
ACTION: Final rule.
SUMMARY: We, the U.S. Fish and
Wildlife Service (Service), determine
endangered status under the
Endangered Species Act of 1973, as
amended (Act), for Phyllostegia hispida
(no common name), a plant species from
the island of Molokai in the Hawaiian
Islands. This final rule implements the
Federal protections provided by the Act
for this species. We have also
determined that critical habitat for P.
hispida is prudent but not determinable
at this time.
DATES: This rule becomes effective April
16, 2009.
ADDRESSES: This final rule is available
on the Internet at https://

SUPPLEMENTARY INFORMATION:
Background
Phyllostegia hispida is known only
from the island of Molokai, Hawaii,
where 24 wild and 214 outplanted
individuals currently exist. Molokai is
approximately 38 miles (mi) (61
kilometers (km)) long and up to 10 mi
(16 km) wide, and encompasses an area
of about 260 square (sq) mi (674 sq km)
(Foote et al. 1972, p. 11; Department of
Geography 1998, p. 13). Three shield
volcanoes make up most of the land

Frm 00045
Fmt 4700
Sfmt 4700

mass, dividing the island into roughly
three geographic segments: West
Molokai Mountain, East Molokai
Mountain, and a volcano that formed
Kalaupapa Peninsula (Department of
Geography 1998, pp. 11, 13).
The taller and larger East Molokai
Mountain, which makes up eastern
Molokai, rises 4,970 feet (ft) (1,514
meters (m)) above sea level on the
island’s summit at Kamakou and
comprises roughly 50 percent of the
island’s land area (Department of
Geography 1998, p. 11; Foote et al.
1972, p. 11). Phyllostegia hispida is
known only from the wet forests of
eastern Molokai, at elevations from
2,300 to 4,200 ft (700 to 1,280 m)
(Wagner et al. 1999, p. 819). The wet
forests where P. hispida has been
recorded are found only on the
windward side of East Molokai, which
differs topographically from the leeward
side. Precipitous cliffs line the northern
windward coast, with deep inaccessible
valleys dissecting the coastline. The
annual rainfall on the windward side
ranges from 75 to over 150 inches (in)
(200 to over 375 centimeters (cm)),
distributed throughout the year. The
soils are poorly drained and high in
organic matter. The gulches and valleys
are usually very steep, but sometimes
gently sloping (Foote et al. 1972, p. 14).
The native habitats and vegetation of
the Hawaiian Islands have undergone
extreme alterations because of past and
present land use, as well as the
intentional or inadvertent introduction
of nonnative animal and plant species.
Introduced mammals, particularly feral
pigs (Sus scrofa), have greatly affected
native Hawaiian plant communities.
Feral pigs have been described as the
most pervasive and disruptive
nonnative influence on the unique
native forests of the Hawaiian Islands,
and are widely recognized as one of the
greatest threats to forest ecosystems in
Hawaii today (Aplet et al. 1991, p. 56;
Anderson and Stone 1993, p. 195; Loope
1998, p. 752). Introduced (nonnative)
plant species, which now comprise
approximately half of the plant taxa in
the islands, have come to dominate
many Hawaiian ecosystems, and
frequently outcompete native plants for
space, light, water, and nutrients, as
well as alter ecosystem function,
rendering habitats unsuitable for native
species (Cuddihy and Stone 1990, pp.
73-91; Vitousek et al. 1997, p. 6).
The plant Phyllostegia hispida has
only a few recorded occurrences and
until recently was thought to be extinct
in the wild. Alterations of the plant’s
native habitat by feral pigs and
nonnative plants have been the primary
threats to P. hispida, in conjunction

11320
Federal Register / Vol. 74, No. 50 / Tuesday, March 17, 2009 / Rules and Regulations
with the threat of predation by feral
pigs, competition with nonnative plants,
and more recently the negative
demographic and genetic consequences
of extremely small population size, as
well as the consequent vulnerability to
extinction through deterministic or
stochastic (chance) events.

Previous Federal Actions
We first identified Phyllostegia
hispida as a candidate for listing in the
September 19, 1997, Notice of Review of
Plant and Animal Taxa that are
Candidates or Proposed for Listing as
Endangered or Threatened Species
(Notice of Review) (62 FR 49397).
Candidates are those taxa for which we
have on file sufficient information on
biological vulnerability and threats to
support preparation of a listing
proposal, but for which development of
a listing regulation is precluded by other
higher priority listing activities.
On May 4, 2004, the Center for
Biological Diversity petitioned the
Service to list 225 species of plants and
animals as endangered under the
provisions of the Act (16 U.S.C. 1531 et
seq.), including Phyllostegia hispida. In
our Notice of Review, dated September
12, 2006 (71 FR 53756), we retained a
listing priority number of 2 for this
species, in accordance with our priority
guidance published on September 21,
1983 (48 FR 43098). A listing priority of
2 reflects threats that are both imminent
and high in magnitude, as well as the
taxonomic classification of P. hispida as
a full species. We determined that
publication of a proposed rule to list the
species was precluded by our work on
higher priority listing actions during the
period from May 2, 2005, through
August 23, 2006 (71 FR 53756).
However, we have since completed
those actions. As such, we had available
resources to propose to list this species.
On February 19, 2008, we published
a proposed rule to list Phyllostegia
hispida as endangered throughout its
range (73 FR 9078). We solicited data
and comments from the public on the
proposed rule. The comment period
opened on February 19, 2008, and
closed on April 21, 2008.
Species Information
Phyllostegia hispida was first
described by William Hillebrand in
1870 from a specimen collected from an
area that he described as the ‘‘heights of
Mopulehu’’ on the island of Molokai
(see ‘‘Type Description,’’ Smithsonian
Institution and National Tropical
Botanical Garden 2008), and is
recognized as a distinct taxon in Wagner
et al. (1999, pp. 817-819). A nonaromatic member of the mint family
VerDate Nov<24>2008
14:14 Mar 16, 2009
Jkt 217001
(Lamiaceae), P. hispida is a loosely
spreading, many-branched vine that
often forms large, tangled masses.
Leaves are thin and flaccid with hispid
hairs (rough with firm, stiff hairs) and
glands. The leaf margins are irregularly
and shallowly lobed. Six to eight white
flowers make up each verticillaster (a
false whorl, composed of a pair of
nearly sessile cymes (a flat-topped or
round-topped flower cluster) in the axils
of opposite leaves or bracts), and nutlets
are approximately 0.1 inches (in) (2.5
millimeters (mm)) long (Wagner et al.
1999, pp. 817-819). No life history
information is currently available on
this species.
The few documented specimens of
Phyllostegia hispida have typically been
found in wet Metrosideros polymorpha
(ohia)–dominated forest, with most at an
elevation between 3,650 and 4,200 ft
(1,112 and 1,280 m). Associated native
species include Cheirodendron
trigynum (olapa), Ilex anomala (aiae),
Cibotium glaucum (hapuu), Broussaisia
argutus (kanawao), Rubus hawaiensis
(akala), Sadleria cyatheoides (amau),
Pipturus albidus (mamaki), Nertera
granadensis (makole), Athyrium
microphyllum (no common name),
Elaphoglossum fauriei (no common
name), and bryophytes (Hawaii
Biodiversity and Mapping Program
(HBMP) 2007).
From 1910 through 1979, a total of 8
occurrences of Phyllostegia hispida
were recorded from the wet forests of
eastern Molokai (HBMP 2007). None of
these historical occurrences have been
relocated during surveys conducted in
the wet forests of east Molokai over the
past several years (The Nature
Conservancy of Hawaii (TNCH) 1997b,
pp. 1-19; Perlman 2006a). In 1996, two
adult plants were found in eastern
Molokai within TNCH’s Kamakou
Preserve, one next to the Pepeopae
Boardwalk and the other east of
Hanalilolilo growing along the fence
within the State of Hawaii’s Puu Alii
Natural Area Reserve (NAR). In 1997, a
single Phyllostegia individual was
discovered on the rim of Pelekunu
Valley in the Puu Alii NAR (HBMP
2005; TNCH 1997b, p. 6). There is some
uncertainty, however, as to whether this
individual was P. hispida, as it was
identified as P. manni by Hawaii
Division of Forestry and Wildlife
(DOFAW) staff, based upon the size and
lobing of its leaves (Hobdy 2006; Lau
2006; Nohara 2006). This individual
plant was protected from feral ungulates
inside a fenced exclosure. Seeds were
collected, and seedlings were produced
by DOFAW and outplanted into the
exclosure with the wild plant (Nohara
2006).

In November 1996, TNCH erected an
exclosure around the Pepeopae
Boardwalk individual and began
frequent, recurrent weeding and
monitoring within the fenced area
(TNCH 1997a, p. 2). They also built an
exclosure approximately 656 ft (200 m)
away for future outplantings of
propagated individuals. Plants grown
from leaf buds collected from the
Pepeopae Boardwalk plant were
outplanted into the exclosure in
December 1997 (TNCH 1998a, p. 7).
They survived through 1998 (TNCH
1998b, Appendix 1, dot 28), but have
since been confirmed dead (Aruch 2006;
Misaki 2006).
The Pepeopae Boardwalk individual
died in 1998 or 1999 (HBMP 2005), and
the wild plant and outplantings in Puu
Alii NAR, which may possibly have
been Phyllostegia manni and not P.
hispida (see above; the question of
taxonomic identity was never resolved),
died several years ago (Perlman 2005;
Wood 2005; Hughes 2006b). The
University of Hawaii’s Lyon Arboretum
has material from the individual that
was growing along the Puu Alii fence
and from the Pepeopae Boardwalk
individual in micropropagation (U.S.
Fish and Wildlife Service 2005).
Surveys have been conducted in the
wet forests of east Molokai, but no
additional Phyllostegia hispida plants
were found. The species was thought to
have been extirpated from the wild until
2005, when two seedlings were found in
a Hanalilolilo stream bank in Kamakou
Preserve, indicating the possible
presence of a mature plant, or plants,
somewhere in the vicinity (TNCH
1997b, pp. 1-19; Perlman 2005; Perlman
2006a; Wood 2006). One of the
seedlings was collected by a botanist
with HBMP and provided to Lyon
Arboretum in Honolulu, which in turn
provided it to Kalaupapa National
Historic Park (KNHP) on Molokai for
attempted propagation. That plant has
since died (Hughes 2006a; Garnett
2006). The other seedling was collected
by a botanist with the National tropical
Botanic Gardens. Cuttings were
propagated from this seedling and
providedto KNHP (Perlman 2006b).
Plants grown from these cuttings have
since been outplanted into TNCH’s
Kamakou Preserve (see below).
Phyllostegia hispida was again
thought to be extirpated from the wild
until a single juvenile plant was
discovered in May 2006 within the Puu
Alii NAR along the Puu Alii fenceline
at 4,100 ft (1,250 m) elevation (Perlman
2006b). Although protected within a 10ft (3-m) diameter fenced exclosure
(Stevens 2006), that individual has died
for unknown reasons (Oppenheimer
E:\FR\FM\17MRR1.SGM
17MRR1
Federal Register / Vol. 74, No. 50 / Tuesday, March 17, 2009 / Rules and Regulations
dwashington3 on PROD1PC60 with RULES
2007). However, 10 new wild plants
were discovered in April 2007: 9 within
Kamakou Preserve and 1 within Puu
Alii NAR. Four of the individuals found
within Kamakou Preserve were
seedlings that were closely clustered
next to a fenceline. These were
protected with temporary fencing;
however, two of these individuals are
now dead. Two of the remaining eight
wild individuals discovered in April
2007 are mature and have fruited and
produced seeds. Seeds and cuttings
have been removed from these
individuals for attempted cultivation
(Oppenheimer 2008b). Other than the
two remaining seedlings that were
protected with temporary fencing, the
remainder of the wild individuals are
not currently protected within
exclosures.
Since April 2007, 15 additional
Phyllostegia hispida individuals have
been found within Kamakou Preserve
while conducting Rubus argutus
(Florida prickly blackberry) control trips
(Oppenheimer 2008a,b; Oppenheimer
2008d). Most of the remaining wild
individuals, which now number 24, are
located on landslides or in windthrow
areas (areas in which trees have been
uprooted or overthrown by wind)
(Oppenheimer 2008b,c).
In addition, several outplantings of
cultivated individuals have been
completed within TNCH’s Kamakou
Preserve as of April 2007. Twelve
individuals were outplanted into
exclosures in April 2007, and 11 of
these were still doing well as of April
2008. Another 12 were outplanted in
June 2007, all of which remained as of
April 2008 (Oppenheimer 2008b). A
third outplanting of 6 plants was done
in August 2007 (Oppenheimer 2008b),
another 124 individuals were
outplanted in August 2008
(Oppenheimer 2008d), and 61 more
were outplanted in September 2008
(Oppenheimer 2008c), bringing the total
number of Phyllostegia hispida plants in
the wild to 24 naturally occurring and
214 outplanted individuals. One of the
wild individuals is located within Puu
Alii NAR; all of the remaining
individuals are located within Kamakou
Preserve.
Summary of Comments and
Recommendations
In the proposed rule published on
February 19, 2008 (73 FR 9078), we
requested that all interested parties
submit written comments on the
proposal by April 21, 2008. We also
contacted appropriate Federal and State
agencies, scientific experts and
organizations, and other interested
parties and invited them to comment on
VerDate Nov<24>2008
14:14 Mar 16, 2009
Jkt 217001
the proposal. Newspaper notices
inviting general public comment were
published in the Honolulu Advertiser
and Molokai Advertiser News. We did
not receive any requests for a public
hearing.
During the comment period for the
proposed rule, we received one written
public comment in support of listing
Phyllostegia hispida with endangered
status. In addition, the commenter
concurred with our assessment that feral
pigs and invasive, nonnative plants are
both important and immediate threats to
Hawaii’s native plants and to P. hispida
in particular. No further additional
information was offered beyond these
statements of support; therefore we will
not address this comment further here.
Peer Review
In accordance with our peer review
policy published on July 1, 1994 (59 FR
34270), we solicited expert opinion
from seven individuals with scientific
expertise that included familiarity with
Phyllostegia hispida and its habitat,
biological needs, and threats. We
received written comments from two
experts, both of whom agreed with the
assessment that P. hispida meets the
definition of an endangered species. In
addition, both experts pointed out that
while the continuing invasion of alien
plants and feral ungulates undoubtedly
poses threats to the species and its
habitat, the limited area currently
occupied by P. hispida has not yet
become highly modified by nonnative
plants and feral pigs, due to ongoing
management by TNCH. The remaining
plants are found in a native-dominated
plant community within TNCH’s
Kamakou Preserve where control efforts
for both alien plants and feral ungulates
are ongoing. Both experts also point out
that they believe P. hispida may be
dependent upon tree-fall openings in
the canopy or similar disturbances that
provide increased sunlight for
germination. Information provided by
the peer reviewers has been
incorporated into this final rule.
Summary of Factors Affecting the
Species
Section 4 of the Act and its
implementing regulations (50 CFR 424)
set forth the procedures for adding
species to the Federal Lists of
Endangered and Threatened Wildlife
and Plants. A species may be
determined to be an endangered or
threatened species due to one or more
of the five factors described in section
4(a)(1) of the Act: (A) The present or
threatened destruction, modification, or
curtailment of its habitat or range; (B)
overutilization for commercial,
PO 00000
Frm 00047
Fmt 4700
Sfmt 4700
11321
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. Listing actions may be
warranted based on any of the above
threat factors, singly or in combination.
Each of these factors is discussed below.
A. The Present or Threatened
Destruction, Modification, or
Curtailment of its Habitat or Range
As with virtually every other native
plant community in the islands, the wet
forests of Molokai where Phyllostegia
hispida occurs have been affected by
introduced (nonnative) feral pigs and
introduced (nonnative) plants (DOFAW
1991, pp. 3, 14-23; TNCH 1994, pp. 6,
9-12; HBMP 2007). The poor
reproduction and survivorship of P.
hispida clearly indicate that the current
conditions are less than optimal for this
species, although we do not yet fully
understand the specific mechanisms
that are undermining its viability.
Feral Pigs
European pigs, introduced to Hawaii
by Captain James Cook in 1778,
hybridized with domesticated
Polynesian pigs, became feral, and
invaded forested areas, especially wet
and mesic forests and dry areas at high
elevations. They are currently present
on Kauai, Niihau, Oahu, Molokai, Maui,
and Hawaii. These introduced feral pigs
are extremely destructive and have both
direct and indirect impacts on native
plant communities. While rooting in the
earth in search of invertebrates and
plant material, feral pigs directly affect
native plants by disturbing and
destroying vegetative cover, trampling
plants and seedlings, and possibly
reducing or eliminating plant
regeneration by damaging or eating
seeds and seedlings (further discussion
of predation is under Factor C, below).
Feral pigs are a major vector for the
establishment and spread of competing
invasive, nonnative plant species, by
dispersing these plant seeds on their
hooves and coats as well as through
their digestive tracts, and by fertilizing
the disturbed soil through their feces.
Feral pigs feed preferentially on the
fruits of many nonnative plants, such as
Passiflora tarminiana (banana poka) and
Psidium cattleianum (strawberry guava),
thereby facilitating the spread of these
invasive species, and also contribute to
erosion by clearing vegetation and
creating large areas of disturbed soil,
especially on slopes (Aplet et al. 1991,
p. 56; Smith 1985, pp. 190, 192, 196,
200, 204, 230-231; Stone 1985, pp. 254255, 262-264; Medeiros et al. 1986, pp.

Tomich 1986, pp. 120-126; Cuddihy and
Stone 1990, pp. 64-65; Loope et al.
1991, pp. 1-21; Wagner et al. 1999, p.
52).
Feral pigs are present in the wet forest
habitat formerly and currently inhabited
by Phyllostegia hispida within Puu Alii
NAR and Kamakou Preserve, and
although control efforts are underway,
they continue to degrade the condition
of the forest there (DOFAW 1991, pp. 3,
14-23; TNCH 1994, pp. 6, 9-12; HBMP
2007). They are considered a major
threat to native species and to the
overall health of the watershed in which
P. hispida occurs (DOFAW 1991, pp. 3,
14-23; TNCH 1994, pp. 6, 9-12).
Significant management actions are
directed at feral ungulate control in the
area where P. hispida has been found
within Puu Alii NAR and Kamakou
Preserve on Molokai, such as large-scale
watershed fencing, construction of
ungulate exclosures around rare plants,
and hunting of feral pigs by both staff
and the public (TNCH 1997a, pp. 2-3;
TNCH 1998a, pp. 1-2, 7; DOFAW 2000,
pp. 3, 12; HBMP 2007). When the
individual P. hispida was discovered in
1996 next to the boardwalk at Pepeopae,
TNCH noted signs of feral pig presence
(e.g., droppings, evidence of rooting,
wallows) in the vicinity (HPMP 2007)
and immediately erected a fenced
exclosure around the plant to protect it
(TNCH 1997a, pp. 2-3). Similarly, a
fenced exclosure was erected around the
individual that was discovered within
the Puu Alii NAR in 1997 to protect it
from feral pigs (Nohara 2006). The
juvenile plant discovered within the
Puu Alii NAR in 2005 was immediately
fenced to protect it from feral pigs
(Stevens 2006), as were four of the most
recently discovered plants along the
fenceline within Kamakou Preserve
(Oppenheimer 2007). Most of the wild
individuals, however, are not currently
protected within exclosures, and despite
ongoing control efforts, feral pigs persist
in the range of P. hispida.
Feral pigs have been described as the
most pervasive and disruptive
nonnative influence on the unique
native forests of the Hawaiian Islands,
and are widely recognized as one of the
greatest current threats to forest
ecosystems in Hawaii (Aplet et al. 1991,
p. 56; Anderson and Stone 1993, p. 195;
Loope 1998, pp. 752, 769-770). Feral
pigs continue to persist despite control
efforts, and fencing protects individual
plants only temporarily. Furthermore,
the remote and rugged terrain of the
islands makes the long-term
maintenance of fencing difficult.
Because of their high rate of
reproduction, more than 40 percent of
VerDate Nov<24>2008
14:14 Mar 16, 2009
Jkt 217001
the feral pig population must be
removed annually before any decline in
numbers is observed (Hess et al. 2006,
p. 39). The most intensive feral pig
eradication programs in the Hawaiian
Islands have taken years of continuous
effort to achieve effective control, even
within fenced areas (Hess et al. 2006).
Even though two peer reviewers have
suggested that the habitat currently
occupied by Phyllostegia hispida on
TNCH land has not yet been highly
modified by feral pigs, due to the welldocumented negative impacts of feral
pigs on native Hawaiian plant
communities, the known habitat
degradation caused by feral pigs in the
habitat occupied by P. hispida, and the
continuing presence of feral pigs in the
limited area where P. hispida is found,
we consider habitat modification and
degradation by feral pigs to be an
immediate and ongoing threat to this
species throughout its range, and we
have no indication that this threat is
likely to be significantly ameliorated in
the near future.
Nonnative Plants
Introduced, nonnative plant species
are a pervasive threat to the native flora
throughout the Hawaiian Islands. Of the
current total of nearly 2,000 native and
naturalized plant taxa, approximately
half are introduced, nonnative species
from other parts of the world, and
nearly 100 of these are considered
invasive pest species (Smith 1985, p.
180). On the Hawaiian Islands and other
tropical islands, studies have shown
that many of these introduced plant taxa
outcompete and displace native plants,
and often alter the habitat to the point
that it is no longer suitable for the native
plant species; these studies include
nonnative pest plants found in habitat
similar to that of Phyllostegia hispida
(Smathers and Gardner 1978, pp. 274275; Smith 1985, pp. 196, 206, 230;
Loope and Medeiros 1992, pp. 7-8;
Medeiros et al. 1992, pp. 30-32; Ellshoff
et al. 1995, pp. 1-5; Meyer and Florence
1996, pp. 777-780; Medeiros et al. 1997,
pp. 30-32; Loope et al. 2004, pp. 14721473). In particular, nonnative pest
plants may make habitat less suitable for
native plants by modifying availability
of light, altering soil-water regimes,
modifying nutrient cycling, or altering
fire characteristics of native plant
communities (Smith 1985, pp. 206, 217,
225, 227-233; Cuddihy and Stone 1990,
p. 74).
Although there is no empirical
evidence specific to Phyllostegia
hispida due to the lack of research on
the species, scientists familiar with P.
hispida believe it does not handle either
shade or competition well
PO 00000
Frm 00048
Fmt 4700
Sfmt 4700
(Oppenheimer 2007), and nonnative
plants are likely to contribute to both of
these conditions. Examples of some of
the nonnative plants documented in the
areas formerly occupied by P. hispida
include Axonopus fissifolius (narrowleaved carpetgrass), Clidemia hirta
(Koster’s curse), Erechtites valerianifolia
(fireweed), Juncus effuses (Japanese mat
rush), Rubus rosifolius (thimbleberry),
and Sacciolepis indica (Glenwood
grass). Rubus rosifolius and R. argutus
are scattered throughout the area in
which P. hispida currently exists, and
are targets of control by TNCH staff in
the area (Oppenheimer 2008a). Because
of demonstrated habitat modification
and resource competition by nonnative
plant species in habitat similar to the
wet forest habitat of P. hispida, and the
ongoing need for control of invasive
nonnative plant species in the area
currently occupied by P. hispida, we
consider habitat modification and
degradation by nonnative plants to be
an immediate and ongoing threat to this
species throughout its range.
To date, successful eradication or
control of invasive alien plants has only
been achieved on a very small scale, and
then usually when control efforts have
been initiated in the early stages of
establishment (Mack and Lonsdale
2002, p. 166). Many of the invasive,
nonnative plants in Hawaii are so
widespread and easily dispersed that
some researchers question whether
eradication is a realistic goal (e.g., Mack
and Lonsdale 2002, p. 165). On average,
40 new plant species have been
introduced to the Hawaiian Islands
every year over the past two centuries
(Loope 1998, p. 752). Although
managers are attempting to control
nonnative plants, resources to support
such efforts are often limited (e.g., Holt
1992, p. 527), and invasive nonnative
plants persist in most areas in spite of
such efforts. In addition, the control of
introduced ungulates such as feral pigs,
which contribute to the spread of alien
plant species, is viewed as a
prerequisite to the effective control of
nonnative plants (e.g., Holt 1992, p.
527). Therefore, due to the ubiquitous
nature of the invasive plant problem in
the Hawaiian Islands, the extreme
difficulty of eradicating invasive,
nonnative plant species that have
become widespread and wellestablished, and the continuing
presence of introduced ungulates that
contribute to the spread and
establishment of nonnative plants, we
have no indication that this threat to
Phyllostegia hispida is likely to be
significantly reduced any time in the
near future.
E:\FR\FM\17MRR1.SGM
17MRR1
Federal Register / Vol. 74, No. 50 / Tuesday, March 17, 2009 / Rules and Regulations
In summary, feral pigs contribute to
the modification and degradation of
Phyllostegia hispida’s habitat by
disturbing and destroying vegetative
cover, trampling plants and seedlings,
reducing or eliminating plant
regeneration by damaging or eating
seeds and seedlings, and increasing
erosion by creating large areas of bare
soil. Feral pigs are also a major vector
for the dispersal of invasive, nonnative
plant species that pose a threat to
P.hispida. The presence of nonnative
plant species contributes to the
modification and degradation of P.
hispida’s habitat by modifying
availability of light, altering soil-water
regimes, modifying nutrient cycling,
and changing the fire characteristics of
the native plant community. Evidence
suggests that P. hispida is negatively
affected by shade and competition, both
conditions exacerbated by invasive
nonnative plants. We therefore find that
habitat modification and degradation by
feral pigs and nonnative plants poses an
immediate and ongoing threat to
Phyllostegia hispida, despite the
occurrence of the species on protected
lands, and we have no indication that
this threat is likely to be significantly
ameliorated in the near future.
dwashington3 on PROD1PC60 with RULES
B. Overutilization for Commercial,
Recreational, Scientific, or Educational
Purposes
Overutilization for commercial,
recreational, scientific, or educational
purposes is not known to be a threat to
Phyllostegia hispida in any portion of
its range, and as such is not addressed
in this rule.
C. Disease or Predation
Because the native vegetation of
Hawaii evolved without any browsing
or grazing mammals present, many
plant species do not have natural
defenses against such impacts (Carlquist
1980, pp. 173-175; Lamoureux 1994, pp.
54-55). Native plants such as
Phyllostegia hispida do not have
physical or chemical adaptations, such
as thorns or noxious compounds, to
protect them, thereby rendering them
particularly vulnerable to predation by
feral pigs or other ungulates
(Department of Geography 1998, pp.
137-138; Carlquist 1980, p. 175).
Browsing by ungulates has been
observed on many other native plants,
including common and rare or
endangered species (Cuddihy and Stone
1990, pp. 64-65). In a study of feral pig
populations in the Kipahulu Valley on
the island of Maui, feral pigs were
observed feeding on at least 40 plant
species in the rainforest ecosystem, 75
percent of which were native plants
VerDate Nov<24>2008
14:14 Mar 16, 2009
Jkt 217001
occurring in the herbaceous understory
and subcanopy layer (Diong 1982, p.
160). Therefore, even though we have
no evidence of direct browsing for P.
hispida, given the presence of feral pigs
in the area where P. hispida occurs, we
consider it likely that feral pigs may
affect the species directly through
predation. As described above under
Factor A, due to the persistence of feral
pigs in the limited range of P. hispida
in spite of control efforts, and the
likelihood that their presence will
continue, we believe feral pigs pose an
immediate and ongoing threat to the
species throughout its range, and that
this threat is unlikely to be significantly
reduced in the near future.
D. The Inadequacy of Existing
Regulatory Mechanisms
Of the 238 known individuals of
Phyllostegia hispida, 24 wild and 214
recently outplanted, 237 occur on
TNCH’s Kamakou Preserve. TNCH
manages this private land for the benefit
of threatened and endangered species
and ecosystems. The management
efforts at TNCH’s Kamakou Preserve
include control of nonnative plants and
feral pigs, as well as fencing, all of
which benefit P. hispida. However, as
noted in the discussion of Factor A
above, the eradication of nonnative
plants and feral pigs, even within
fenced areas under active management,
is a difficult and extremely lengthy task.
The continuing presence of nonnative
plants and feral pigs within the fenced
area of the preserve, in concert with the
threat of very small population size and
limited number of reproductive
individuals, which will be discussed in
Factor E, renders P. hispida vulnerable
to extinction due to these threats despite
beneficial management on the Kamakou
Preserve. The threat of extinction is not
posed, however, by an inadequacy of
regulatory mechanisms on TNCH lands.
Only one known individual of
Phyllostegia hispida is found on State
lands, in the Puu Alii NAR. Hawaii
Administrative Rules 13-209 provide
protections for this single individual,
including a prohibition against removal,
injury, or killing, and a prohibition
against the introduction of plants or
animals. The State has been working to
fence greater areas of the NAR and to
eradicate feral pigs and nonnative plants
within the fenced areas, but this work
is not yet complete. As noted in the
discussion of Factor A above, the
eradication of nonnative plants and feral
pigs, even within fenced areas under
active management, is a difficult and
extremely lengthy task. Although some
regulatory protections are in place on
the NAR that benefit P. hispida, only
PO 00000
Frm 00049
Fmt 4700
Sfmt 4700
11323
one single plant occurs under these
protections. This fact, in conjunction
with the persistence of nonnative plants
and feral pigs, small population size,
and limited number of reproductive
individuals of the species remaining,
renders P. hispida vulnerable to
extinction due to these threats despite
the protections on the Puu Alii NAR.
The threat of extinction is not posed,
however, by an inadequacy of regulatory
mechanisms on the NAR. The regulatory
mechanisms that provide for the control
of threats to P. hispida on the Puu Alii
NAR appear to be adequate, but as the
success of these control efforts has yet
to be realized, the threats continue at
present.
We find that where individuals of
Phyllostegia hispida are currently
found, the inadequacy of regulatory
mechanisms does not pose a threat to
the species. However, should the
recovery of the species eventually
require reintroductions in other areas,
this factor may pose a potential
impediment to recovery.
E. Other Natural or Manmade Factors
Affecting Its Continued Existence
One of the most significant threats to
Phyllostegia hispida is its extremely low
numbers and highly restricted
distribution. A total of 238 plants are
currently known to exist, 24 naturally
occurring and 214 outplanted. Only two
wild individuals are mature and have
fruited and produced seeds. All of the
remaining individuals are young or only
recently established. Survivorship of
known wild individuals has been poor,
and although outplantings have been
attempted, none of these outplantings
has yet proven successful for more than
the short term. Although propagules of
P. hispida have been collected on an
opportunistic basis and some controlled
propagation of the species has taken
place, there is no dedicated funding for
propagation of the species and no
formal plan exists for outplanting and
reintroduction.
Deterministic factors, such as habitat
alteration or loss of a key pollinator,
may have reduced this population to
such a small size that it is now
susceptible to a stochastic extinction
´
event (Gilpin and Soule 1986, pp. 2425). Species that are known from few
wild individuals and are endemic to a
single, small island are inherently more
vulnerable to extinction than
widespread species because of the
higher risks posed to a few populations
and individuals by genetic bottlenecks,
random demographic fluctuations, and
localized catastrophes, such as
hurricanes and disease outbreaks
(Mangel and Tier 1994, pp. 607-614;
E:\FR\FM\17MRR1.SGM
17MRR1
11324
Federal Register / Vol. 74, No. 50 / Tuesday, March 17, 2009 / Rules and Regulations
dwashington3 on PROD1PC60 with RULES
Pimm et al. 1988, pp. 757-785). In the
case of Phyllostegia hispida, the entire
population of the species is small and
restricted to a highly localized
geographic area, rendering it highly
vulnerable to the risk of extinction in
the wild due to the lack of redundancy
in populations. In addition, the lack of
reproductive individuals and skewing of
the population toward young plants
poses a significant threat to the species,
as recruitment may not be sufficient to
offset mortality in the population. These
consequences of small population size
(e.g., insufficient natural reproduction,
loss of genetic diversity), in conjunction
with the risk of losing the entire
population in the wild due to factors
such as localized events (e.g.,
hurricanes) and threats posed by
ungulates, render the species highly
vulnerable to extinction at any time.
Although some species are naturally
rare, the poor survivorship of P. hispida
suggests that the requisite biological or
ecological needs of the species are not
being met under current conditions. The
reasons for the poor survivorship and
lack of reproduction observed in this
species are not known.
All of these negative demographic
factors, as well as the vulnerability of
extinction of the population from a
catastrophic natural event, pose
immediate and significant threats to the
species despite the fact that it currently
occurs on protected lands, including
State and TNCH reserves. Small
population size has therefore become a
primary and immediate threat to this
species, and given the current size and
composition of the population, we do
not foresee the likelihood of this threat
lessening to any significant degree any
time in the near future.
Conclusion and Determination
We have carefully assessed the best
scientific and commercial information
available regarding the past, present,
and future threats to Phyllostegia
hispida. The species’ extremely low
numbers and highly restricted
geographic range make it particularly
susceptible to extinction at any time
from random events such as hurricanes
(Factor E). In addition, the lack of
mature reproductive individuals poses
an immediate threat to the species
(Factor E). Although the species is
found on protected lands with ongoing
management efforts, as described above,
we find that it nonetheless faces
continuing threats from habitat
destruction and degradation due to feral
pig activity and invasive nonnative
plants (Factor A), competition with
nonnative plant species (Factor A), and
predation by nonnative mammals
VerDate Nov<24>2008
14:14 Mar 16, 2009
Jkt 217001
(Factor C). The pervasive nature of feral
pigs and invasive plants on the island
of Molokai makes it unlikely that
control efforts will significantly reduce
the degree of threat to the species
anytime in the near future; therefore we
find that these factors, in combination
with the extremely low number of
reproductive individuals and limited
distribution of the population, pose a
significant and immediate threat to P.
hispida and place the species at current
risk of extinction throughout its range.
The Act defines an endangered
species as ‘‘any species which is in
danger of extinction throughout all or a
significant portion of its range.’’
Phyllostegia hispida is highly restricted
in its range, currently occurring only
within Puu Alii NAR and the
immediately adjacent Kamakou Preserve
on the island of Molokai. Based on the
immediate and ongoing significant
threats to P. hispida throughout its
entire limited range, as described above,
we consider the species P. hispida to be
in danger of extinction throughout all of
its range. Therefore, we are listing P.
hispida as an endangered species under
the Act. Because we determine that P.
hispida is endangered throughout all of
its range, there is no reason to consider
its status in any significant portion of its
range.
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.
Recognition through listing results in
public awareness and conservation by
Federal, State, and local agencies,
private organizations, and individuals.
The Act encourages cooperation with
the States and requires that recovery
actions be carried out for all listed
species. The protection measures
required of Federal agencies and the
prohibitions against certain activities
involving listed plants are discussed, in
part, below.
Section 7(a) of the Act, as amended,
requires Federal agencies to evaluate
their actions with respect to any species
that is proposed or listed as endangered
or threatened and with respect to its
critical habitat, if any is designated.
Regulations implementing this
interagency cooperation provision of the
Act are codified at 50 CFR part 402.
Section 7(a)(4) of the Act requires
Federal agencies to confer with the
Service on any action that is likely to
jeopardize the continued existence of a
species proposed for listing or result in
destruction or adverse modification of
PO 00000
Frm 00050
Fmt 4700
Sfmt 4700
proposed critical habitat. If a species is
listed subsequently, section 7(a)(2) of
the Act requires Federal agencies to
ensure that activities they authorize,
fund, or carry out are not likely to
jeopardize the continued existence of
the species or destroy or adversely
modify its critical habitat. If a Federal
action may adversely affect a listed
species or its critical habitat, the
responsible Federal agency must enter
into formal consultation with the
Service.
For Phyllostegia hispida, Federal
agency actions that may require
consultation as described in the
preceding paragraph include feral
ungulate removal or other management
actions undertaken by the National Park
Service within Puu Alii NAR; the
provision of Federal funds to State and
private entities through Federal
programs, such as the Service’s Partners
for Fish and Wildlife Program, State
Wildlife Grant Program, and Federal
Aid in Wildlife Restoration Program;
and the various grants administered by
the U.S. Department of Agriculture,
Natural Resources Conservation Service.
Other types of actions that may require
consultation include U.S. Army Corps
of Engineers activities, such as the
construction or maintenance of
boardwalks and bridges subject to
section 404 of the Clean Water Act (33
U.S.C. 1344 et seq.).
The Act and its implementing
regulations set forth a series of general
prohibitions and exceptions that apply
to endangered plants. All prohibitions
of section 9(a)(2) of the Act,
implemented by 50 CFR 17.61, apply.
These prohibitions, in part, make it
illegal for any person subject to the
jurisdiction of the United States to
import or export, transport in interstate
or foreign commerce in the course of a
commercial activity, sell or offer for sale
in interstate or foreign commerce, or
remove and reduce to possession the
species from areas under Federal
jurisdiction. In addition, for plants
listed as endangered, the Act prohibits
the malicious damage or destruction on
areas under Federal jurisdiction and the
removal, cutting, digging up, or
damaging or destroying of such plants
in knowing violation of any State law or
regulation, including State criminal
trespass law. Certain exceptions to the
prohibitions apply to agents of the
Service and State conservation agencies.
Although Hawaii has a strong
Endangered Species law (HRS, Sect.
195-D), Phyllostegia hispida is not
currently protected under that law.
Federal listing of P. hispida will
automatically invoke State listing under
Hawaii’s Endangered Species law and

dwashington3 on PROD1PC60 with RULES
supplement the protection available
under other State laws. The Federal
Endangered Species Act will, therefore,
offer additional protection to this
species.
The Act and 50 CFR 17.62 also
provide for the issuance of permits to
carry out otherwise prohibited activities
involving endangered plants under
certain circumstances. Such permits are
available for scientific purposes and to
enhance the propagation or survival of
the species. We anticipate that the only
permits that would be sought or issued
for Phyllostegia hispida would be in
association with recovery efforts, as this
species is not common in cultivation or
the wild. Requests for copies of the
regulations regarding listed species and
inquiries about prohibitions and permits
may be addressed to U.S. Fish and
Wildlife Service, Ecological Services,
Eastside Federal Complex, 911 N.E. 11th
Avenue, Portland, OR 97232-4181

Critical Habitat
Critical habitat is defined in section 3
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 provisions of
section 4 of 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
protections; and
(2) Specific areas outside the
geographical area occupied by a species
at the time it is listed in accordance
with the provisions of section 4 of the
Act, upon a determination by the
Secretary of the Interior that such areas
are essential for the conservation of the
species.
Conservation, as defined under
section 3 of the Act, means to use and
the use of all methods and procedures
which are necessary to bring any
endangered or threatened species to the
point at which the measures provided
under 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
VerDate Nov<24>2008
14:14 Mar 16, 2009
Jkt 217001
prohibition against Federal agencies
carrying out, funding, or authorizing the
destruction or adverse modification of
critical habitat. Section 7(a)(2) of the Act
requires consultation on Federal actions
that may affect 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 does not allow the
government or public to access private
lands. Such designation does not
require implementation of restoration,
recovery, or enhancement measures by
private landowners. Where a landowner
requests Federal agency funding or
authorization for an action that may
affect a listed species or critical habitat,
the consultation requirements of section
7(a)(2) of the Act would apply, but even
in the event of a destruction or adverse
modification finding, the landowner’s
obligation is not to restore or recover the
species, but to implement reasonable
and prudent alternatives to avoid
destruction or adverse modification of
critical habitat.
For inclusion in a critical habitat
designation, the habitat within the
geographical area occupied by the
species at the time of listing must
contain the physical and biological
features essential to the conservation of
the species, and be included only if
those features may require special
management considerations or
protection. Critical habitat designations
identify, to the extent known using the
best scientific data available, habitat
areas that provide essential life cycle
needs of the species (i.e., areas on which
are found the primary constituent
elements (PCEs) laid out in the
appropriate quantity and spatial
arrangement for the conservation of the
species). Under the Act, we can
designate critical habitat in areas
outside the geographical area occupied
by the species at the time it is listed
only when we determine that those
areas are essential for the conservation
of the species.
Section 4 of the Act requires that we
designate critical habitat on the basis of
the best scientific and commercial data
available. Further, our Policy on
Information 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 issued by the
Service, provide criteria, establish
procedures, and provide guidance to
ensure that our decisions are based on
PO 00000
Frm 00051
Fmt 4700
Sfmt 4700
11325
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 developed
during the listing process for the
species. Additional information sources
may include 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, or other unpublished
materials and expert opinion or
personal knowledge.
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 designate
critical habitat at the time a species is
determined to be endangered or
threatened. Our regulations (50 CFR
424.12(a)(1)) state that the designation
of critical habitat is not prudent when
one or both of the following situations
exist: (1) The species is threatened by
taking or other human activity, and
identification of critical habitat can be
expected to increase the degree of threat
to the species, or (2) such designation of
critical habitat would not be beneficial
to the species.
There is no documentation that
Phyllostegia hispida is threatened by
taking or other human activity. In the
absence of finding that the designation
of critical habitat would increase threats
to a species, if there are any benefits to
a critical habitat designation, then a
prudent finding is warranted. The
potential benefits include: (1) Triggering
consultation under section 7 of the Act,
for actions in which there may be a
Federal nexus where it would not
otherwise occur because, for example,
the area is or has become unoccupied or
the occupancy is in question; (2)
focusing conservation activities on the
most essential features and areas; (3)
providing educational benefits to State
or county governments or private
entities; and (4) preventing people from
causing inadvertent harm to the species.
The primary regulatory effect of a
critical habitat designation is the section
7(a)(2) requirement that Federal
agencies refrain from taking any action
that destroys or adversely affects critical
habitat. At present, the only known

extant individuals of Phyllostegia
hispida occur on State and private land,
and all previously known occurrences
have been on State and private lands.
However, the State-owned Puu Alii
NAR falls within the boundaries of the
Kalaupapa National Historic Park, and
the National Park Service may need to
consult with the Service in the future
should they determine that actions they
intend to fund, carry out, or authorize
within the NAR may affect P. hispida or
destroy or adversely affect critical
habitat. In addition, lands that may be
designated as critical habitat in the
future for this species may be subject to
Federal actions that trigger the section 7
consultation requirement, such as the
granting of Federal monies for
conservation projects or the need for
Federal permits for projects, such as the
construction and maintenance of
boardwalks and bridges subject to
section 404 of the Clean Water Act (33
U.S.C. 1344 et seq.). There may also be
some educational or informational
benefits to the designation of critical
habitat. Educational benefits include the
notification of land owners, land
managers, and the general public of the
importance of protecting the habitat of
this species. In the case of P. hispida,
these aspects of critical habitat
designation would potentially benefit
the conservation of the species.
Therefore, since we have determined
that the designation of critical habitat
will not likely increase the degree of
threat to the species and may provide
some measure of benefit, we find that
designation of critical habitat is prudent
for P. hispida.
Critical Habitat Determinability
As stated above, section 4(a)(3) of the
Act requires the designation of critical
habitat concurrently with the species’
listing ‘‘to the maximum extent prudent
and determinable.’’ Our regulations at
50 CFR 424.12(a)(2) state that critical
habitat is not determinable when one or
both of the following situations exist:
(i) Information sufficient to perform
required analyses of the impacts of the
designation is lacking, or
(ii) The biological needs of the species
are not sufficiently well known to
permit identification of an area as
critical habitat.
When critical habitat is not
determinable, the Act provides for an
additional year to publish a critical
habitat designation (16 U.S.C.
1533(b)(6)(C)(ii)).
In accordance with section 3(5)(A)(i)
of the Act and regulations at 50 CFR
424.12, in determining which areas
occupied by the species at the time of
listing to designate as critical habitat,
VerDate Nov<24>2008

we consider those physical and
biological features essential to the
conservation of the species that may
require special management
considerations or protection. We
consider the physical or biological
features to be the PCEs laid out in the
appropriate quantity and spatial
arrangement for the conservation of the
species. The PCEs include, but are not
limited to:
(1) Space for individual and
population growth and for normal
behavior;
(2) Food, water, air, light, minerals, or
other nutritional or physiological
requirements;
(3) Cover or shelter;
(4) Sites for breeding, reproduction,
and rearing (or development) of
offspring; and
(5) Habitats that are protected from
disturbance or are representative of the
historical geographical and ecological
distributions of a species.
We are currently unable to identify
the primary constituent elements for
Phyllostegia hispida, because those
physical and biological features that are
essential to the conservation of this
species are not known at this time. As
discussed in the ‘‘Species Information’’
section of this rule, between the years
1910 and 1996 only 10 occurrences of
P. hispida were documented, and the
location information for these
occurrences was recorded at a relatively
coarse scale. Elevations are known only
for the few individuals discovered
within the last 10 years. From 1996
through 2005, a total of only 6 plants (3
adults, 2 seedlings, and 1 juvenile) were
located, all existing only as single
individuals in disparate locations. All of
the previously known adults died
without reproducing naturally in the
wild. Currently, there are 24 individuals
known to naturally exist in the wild,
only 2 of which are mature. Seeds and
cuttings have been removed from these
two individuals for attempted
cultivation (Oppenheimer 2008b). As of
April 2008, an additional 214
individuals produced from cuttings and
outplanted into exclosures in Kamakou
Preserve are also extant.
The reasons for the deaths of the
Phyllostegia hispida individuals
summarized in the ‘‘Species
Information’’ section of this rule are
unknown, as are the reasons for poor
natural reproduction in the wild. Key
features of the plant’s life history, such
as longevity, dispersal mechanisms, or
vectors for pollination, are unknown.
With so few recorded occurrences of
the species, little is known of
Phyllostegia hispida in terms of what
this plant needs to survive and
PO 00000
Frm 00052

reproduce successfully in the wild. The
poor viability of the P. hispida
occurrences observed in recent years
indicates that current conditions are not
sufficient to meet the basic biological
requirements of this species. Although
two mature plants that are producing
fruits were recently discovered, there
has yet to be an observation of an
individual or population of P. hispida
that has successfully produced
surviving young in the wild. As the
successful survival and reproduction of
the species in the wild has not yet been
documented, the optimal conditions
that would provide the biological or
ecological requisites of the species are
not known. Although, as described
above, we can surmise that habitat
degradation from a variety of factors has
contributed to the decline of the species,
we do not know specifically what
essential physical or biological features
of that habitat are currently lacking for
P. hispida. As we are unable to identify
the physical and biological features
essential to the conservation of P.
hispida, we are unable to identify areas
that contain these features and that
might qualify for designation as critical
habitat.
Although we have determined that
the designation of critical habitat is
prudent for Phyllostegia hispida, the
biological needs of the species are not
sufficiently well known to permit
identification of the physical and
biological features that may be essential
for the conservation of the species, or
those areas essential to the conservation
of the species. Therefore, we find that
critical habitat for P. hispida is not
determinable at this time. The recent
outplanting of more than 200 new
seedlings into the Kamakou Preserve
presents us with an opportunity to
study the growth of these plants and
better determine the physical and
biological features that may be essential
for the conservation of the species. We
intend to use the iterative information
gained from this continuing research
into the essential life history
requirements of P. hispida to facilitate
identification of essential features and
areas. In addition, we will evaluate the
needs of P. hispida within the ecological
context of the broader ecosystem in
which it occurs, similar to the approach
that was recently proposed for 47
species endemic to the island of Kauai
(October 21, 2008; 73 FR 62592), and
will consider the utility of using this
approach for this species as well.

anticipates that 80 percent of the
Federal commercial quota of 3,777,443
lb (1,713 mt) for the 2009 Winter I
period will be harvested by March 19,
2009. Therefore, to maintain the
integrity of the 2010 Winter I period
quota by avoiding quota overages, the
commercial scup possession limit will
be reduced from 30,000 lb (13,608 kg) to
1,000 lb (454 kg) of scup per trip. This
possession limit will remain in effect
until the end of the Winter I period

SUPPLEMENTARY INFORMATION:
Background
Phyllostegia hispida is known only from the island of Molokai,
Hawaii, where 24 wild and 214 outplanted individuals currently exist.
Molokai is approximately 38 miles (mi) (61 kilometers (km)) long and up
to 10 mi (16 km) wide, and encompasses an area of about 260 square (sq)
mi (674 sq km) (Foote et al. 1972, p. 11; Department of Geography 1998,
p. 13). Three shield volcanoes make up most of the land mass, dividing
the island into roughly three geographic segments: West Molokai
Mountain, East Molokai Mountain, and a volcano that formed Kalaupapa
Peninsula (Department of Geography 1998, pp. 11, 13).
The taller and larger East Molokai Mountain, which makes up eastern
Molokai, rises 4,970 feet (ft) (1,514 meters (m)) above sea level on
the island's summit at Kamakou and comprises roughly 50 percent of the
island's land area (Department of Geography 1998, p. 11; Foote et al.
1972, p. 11). Phyllostegia hispida is known only from the wet forests
of eastern Molokai, at elevations from 2,300 to 4,200 ft (700 to 1,280
m) (Wagner et al. 1999, p. 819). The wet forests where P. hispida has
been recorded are found only on the windward side of East Molokai,
which differs topographically from the leeward side. Precipitous cliffs
line the northern windward coast, with deep inaccessible valleys
dissecting the coastline. The annual rainfall on the windward side
ranges from 75 to over 150 inches (in) (200 to over 375 centimeters
(cm)), distributed throughout the year. The soils are poorly drained
and high in organic matter. The gulches and valleys are usually very
steep, but sometimes gently sloping (Foote et al. 1972, p. 14).
The native habitats and vegetation of the Hawaiian Islands have
undergone extreme alterations because of past and present land use, as
well as the intentional or inadvertent introduction of nonnative animal
and plant species. Introduced mammals, particularly feral pigs (Sus
scrofa), have greatly affected native Hawaiian plant communities. Feral
pigs have been described as the most pervasive and disruptive nonnative
influence on the unique native forests of the Hawaiian Islands, and are
widely recognized as one of the greatest threats to forest ecosystems
in Hawaii today (Aplet et al. 1991, p. 56; Anderson and Stone 1993, p.
195; Loope 1998, p. 752). Introduced (nonnative) plant species, which
now comprise approximately half of the plant taxa in the islands, have
come to dominate many Hawaiian ecosystems, and frequently outcompete
native plants for space, light, water, and nutrients, as well as alter
ecosystem function, rendering habitats unsuitable for native species
(Cuddihy and Stone 1990, pp. 73-91; Vitousek et al. 1997, p. 6).
The plant Phyllostegia hispida has only a few recorded occurrences
and until recently was thought to be extinct in the wild. Alterations
of the plant's native habitat by feral pigs and nonnative plants have
been the primary threats to P. hispida, in conjunction
[[Page 11320]]
with the threat of predation by feral pigs, competition with nonnative
plants, and more recently the negative demographic and genetic
consequences of extremely small population size, as well as the
consequent vulnerability to extinction through deterministic or
stochastic (chance) events.
Previous Federal Actions
We first identified Phyllostegia hispida as a candidate for listing
in the September 19, 1997, Notice of Review of Plant and Animal Taxa
that are Candidates or Proposed for Listing as Endangered or Threatened
Species (Notice of Review) (62 FR 49397). Candidates are those taxa for
which we have on file sufficient information on biological
vulnerability and threats to support preparation of a listing proposal,
but for which development of a listing regulation is precluded by other
higher priority listing activities.
On May 4, 2004, the Center for Biological Diversity petitioned the
Service to list 225 species of plants and animals as endangered under
the provisions of the Act (16 U.S.C. 1531 et seq.), including
Phyllostegia hispida. In our Notice of Review, dated September 12, 2006
(71 FR 53756), we retained a listing priority number of 2 for this
species, in accordance with our priority guidance published on
September 21, 1983 (48 FR 43098). A listing priority of 2 reflects
threats that are both imminent and high in magnitude, as well as the
taxonomic classification of P. hispida as a full species. We determined
that publication of a proposed rule to list the species was precluded
by our work on higher priority listing actions during the period from
May 2, 2005, through August 23, 2006 (71 FR 53756). However, we have
since completed those actions. As such, we had available resources to
propose to list this species.
On February 19, 2008, we published a proposed rule to list
Phyllostegia hispida as endangered throughout its range (73 FR 9078).
We solicited data and comments from the public on the proposed rule.
The comment period opened on February 19, 2008, and closed on April 21,
2008.
Species Information
Phyllostegia hispida was first described by William Hillebrand in
1870 from a specimen collected from an area that he described as the
``heights of Mopulehu'' on the island of Molokai (see ``Type
Description,'' Smithsonian Institution and National Tropical Botanical
Garden 2008), and is recognized as a distinct taxon in Wagner et al.
(1999, pp. 817-819). A non-aromatic member of the mint family
(Lamiaceae), P. hispida is a loosely spreading, many-branched vine that
often forms large, tangled masses. Leaves are thin and flaccid with
hispid hairs (rough with firm, stiff hairs) and glands. The leaf
margins are irregularly and shallowly lobed. Six to eight white flowers
make up each verticillaster (a false whorl, composed of a pair of
nearly sessile cymes (a flat-topped or round-topped flower cluster) in
the axils of opposite leaves or bracts), and nutlets are approximately
0.1 inches (in) (2.5 millimeters (mm)) long (Wagner et al. 1999, pp.
817-819). No life history information is currently available on this
species.
The few documented specimens of Phyllostegia hispida have typically
been found in wet Metrosideros polymorpha (ohia)-dominated forest, with
most at an elevation between 3,650 and 4,200 ft (1,112 and 1,280 m).
Associated native species include Cheirodendron trigynum (olapa), Ilex
anomala (aiae), Cibotium glaucum (hapuu), Broussaisia argutus
(kanawao), Rubus hawaiensis (akala), Sadleria cyatheoides (amau),
Pipturus albidus (mamaki), Nertera granadensis (makole), Athyrium
microphyllum (no common name), Elaphoglossum fauriei (no common name),
and bryophytes (Hawaii Biodiversity and Mapping Program (HBMP) 2007).
From 1910 through 1979, a total of 8 occurrences of Phyllostegia
hispida were recorded from the wet forests of eastern Molokai (HBMP
2007). None of these historical occurrences have been relocated during
surveys conducted in the wet forests of east Molokai over the past
several years (The Nature Conservancy of Hawaii (TNCH) 1997b, pp. 1-19;
Perlman 2006a). In 1996, two adult plants were found in eastern Molokai
within TNCH's Kamakou Preserve, one next to the Pepeopae Boardwalk and
the other east of Hanalilolilo growing along the fence within the State
of Hawaii's Puu Alii Natural Area Reserve (NAR). In 1997, a single
Phyllostegia individual was discovered on the rim of Pelekunu Valley in
the Puu Alii NAR (HBMP 2005; TNCH 1997b, p. 6). There is some
uncertainty, however, as to whether this individual was P. hispida, as
it was identified as P. manni by Hawaii Division of Forestry and
Wildlife (DOFAW) staff, based upon the size and lobing of its leaves
(Hobdy 2006; Lau 2006; Nohara 2006). This individual plant was
protected from feral ungulates inside a fenced exclosure. Seeds were
collected, and seedlings were produced by DOFAW and outplanted into the
exclosure with the wild plant (Nohara 2006).
In November 1996, TNCH erected an exclosure around the Pepeopae
Boardwalk individual and began frequent, recurrent weeding and
monitoring within the fenced area (TNCH 1997a, p. 2). They also built
an exclosure approximately 656 ft (200 m) away for future outplantings
of propagated individuals. Plants grown from leaf buds collected from
the Pepeopae Boardwalk plant were outplanted into the exclosure in
December 1997 (TNCH 1998a, p. 7). They survived through 1998 (TNCH
1998b, Appendix 1, dot 28), but have since been confirmed dead (Aruch
2006; Misaki 2006).
The Pepeopae Boardwalk individual died in 1998 or 1999 (HBMP 2005),
and the wild plant and outplantings in Puu Alii NAR, which may possibly
have been Phyllostegia manni and not P. hispida (see above; the
question of taxonomic identity was never resolved), died several years
ago (Perlman 2005; Wood 2005; Hughes 2006b). The University of Hawaii's
Lyon Arboretum has material from the individual that was growing along
the Puu Alii fence and from the Pepeopae Boardwalk individual in
micropropagation (U.S. Fish and Wildlife Service 2005).
Surveys have been conducted in the wet forests of east Molokai, but
no additional Phyllostegia hispida plants were found. The species was
thought to have been extirpated from the wild until 2005, when two
seedlings were found in a Hanalilolilo stream bank in Kamakou Preserve,
indicating the possible presence of a mature plant, or plants,
somewhere in the vicinity (TNCH 1997b, pp. 1-19; Perlman 2005; Perlman
2006a; Wood 2006). One of the seedlings was collected by a botanist
with HBMP and provided to Lyon Arboretum in Honolulu, which in turn
provided it to Kalaupapa National Historic Park (KNHP) on Molokai for
attempted propagation. That plant has since died (Hughes 2006a; Garnett
2006). The other seedling was collected by a botanist with the National
tropical Botanic Gardens. Cuttings were propagated from this seedling
and providedto KNHP (Perlman 2006b). Plants grown from these cuttings
have since been outplanted into TNCH's Kamakou Preserve (see below).
Phyllostegia hispida was again thought to be extirpated from the
wild until a single juvenile plant was discovered in May 2006 within
the Puu Alii NAR along the Puu Alii fenceline at 4,100 ft (1,250 m)
elevation (Perlman 2006b). Although protected within a 10-ft (3-m)
diameter fenced exclosure (Stevens 2006), that individual has died for
unknown reasons (Oppenheimer
[[Page 11321]]
2007). However, 10 new wild plants were discovered in April 2007: 9
within Kamakou Preserve and 1 within Puu Alii NAR. Four of the
individuals found within Kamakou Preserve were seedlings that were
closely clustered next to a fenceline. These were protected with
temporary fencing; however, two of these individuals are now dead. Two
of the remaining eight wild individuals discovered in April 2007 are
mature and have fruited and produced seeds. Seeds and cuttings have
been removed from these individuals for attempted cultivation
(Oppenheimer 2008b). Other than the two remaining seedlings that were
protected with temporary fencing, the remainder of the wild individuals
are not currently protected within exclosures.
Since April 2007, 15 additional Phyllostegia hispida individuals
have been found within Kamakou Preserve while conducting Rubus argutus
(Florida prickly blackberry) control trips (Oppenheimer 2008a,b;
Oppenheimer 2008d). Most of the remaining wild individuals, which now
number 24, are located on landslides or in windthrow areas (areas in
which trees have been uprooted or overthrown by wind) (Oppenheimer
2008b,c).
In addition, several outplantings of cultivated individuals have
been completed within TNCH's Kamakou Preserve as of April 2007. Twelve
individuals were outplanted into exclosures in April 2007, and 11 of
these were still doing well as of April 2008. Another 12 were
outplanted in June 2007, all of which remained as of April 2008
(Oppenheimer 2008b). A third outplanting of 6 plants was done in August
2007 (Oppenheimer 2008b), another 124 individuals were outplanted in
August 2008 (Oppenheimer 2008d), and 61 more were outplanted in
September 2008 (Oppenheimer 2008c), bringing the total number of
Phyllostegia hispida plants in the wild to 24 naturally occurring and
214 outplanted individuals. One of the wild individuals is located
within Puu Alii NAR; all of the remaining individuals are located
within Kamakou Preserve.
Summary of Comments and Recommendations
In the proposed rule published on February 19, 2008 (73 FR 9078),
we requested that all interested parties submit written comments on the
proposal by April 21, 2008. We also contacted appropriate Federal and
State agencies, scientific experts and organizations, and other
interested parties and invited them to comment on the proposal.
Newspaper notices inviting general public comment were published in the
Honolulu Advertiser and Molokai Advertiser News. We did not receive any
requests for a public hearing.
During the comment period for the proposed rule, we received one
written public comment in support of listing Phyllostegia hispida with
endangered status. In addition, the commenter concurred with our
assessment that feral pigs and invasive, nonnative plants are both
important and immediate threats to Hawaii's native plants and to P.
hispida in particular. No further additional information was offered
beyond these statements of support; therefore we will not address this
comment further here.
Peer Review
In accordance with our peer review policy published on July 1, 1994
(59 FR 34270), we solicited expert opinion from seven individuals with
scientific expertise that included familiarity with Phyllostegia
hispida and its habitat, biological needs, and threats. We received
written comments from two experts, both of whom agreed with the
assessment that P. hispida meets the definition of an endangered
species. In addition, both experts pointed out that while the
continuing invasion of alien plants and feral ungulates undoubtedly
poses threats to the species and its habitat, the limited area
currently occupied by P. hispida has not yet become highly modified by
nonnative plants and feral pigs, due to ongoing management by TNCH. The
remaining plants are found in a native-dominated plant community within
TNCH's Kamakou Preserve where control efforts for both alien plants and
feral ungulates are ongoing. Both experts also point out that they
believe P. hispida may be dependent upon tree-fall openings in the
canopy or similar disturbances that provide increased sunlight for
germination. Information provided by the peer reviewers has been
incorporated into this final rule.
Summary of Factors Affecting the Species
Section 4 of the Act and its implementing regulations (50 CFR 424)
set forth the procedures for adding species to the Federal Lists of
Endangered and Threatened Wildlife and Plants. A species may be
determined to be an endangered or threatened species due to one or more
of the five factors described in section 4(a)(1) of the Act: (A) The
present or threatened destruction, modification, or curtailment of its
habitat or range; (B) overutilization for commercial, recreational,
scientific, or educational purposes; (C) disease or predation; (D) the
inadequacy of existing regulatory mechanisms; or (E) other natural or
manmade factors affecting its continued existence. Listing actions may
be warranted based on any of the above threat factors, singly or in
combination. Each of these factors is discussed below.
A. The Present or Threatened Destruction, Modification, or Curtailment
of its Habitat or Range
As with virtually every other native plant community in the
islands, the wet forests of Molokai where Phyllostegia hispida occurs
have been affected by introduced (nonnative) feral pigs and introduced
(nonnative) plants (DOFAW 1991, pp. 3, 14-23; TNCH 1994, pp. 6, 9-12;
HBMP 2007). The poor reproduction and survivorship of P. hispida
clearly indicate that the current conditions are less than optimal for
this species, although we do not yet fully understand the specific
mechanisms that are undermining its viability.
Feral Pigs
European pigs, introduced to Hawaii by Captain James Cook in 1778,
hybridized with domesticated Polynesian pigs, became feral, and invaded
forested areas, especially wet and mesic forests and dry areas at high
elevations. They are currently present on Kauai, Niihau, Oahu, Molokai,
Maui, and Hawaii. These introduced feral pigs are extremely destructive
and have both direct and indirect impacts on native plant communities.
While rooting in the earth in search of invertebrates and plant
material, feral pigs directly affect native plants by disturbing and
destroying vegetative cover, trampling plants and seedlings, and
possibly reducing or eliminating plant regeneration by damaging or
eating seeds and seedlings (further discussion of predation is under
Factor C, below). Feral pigs are a major vector for the establishment
and spread of competing invasive, nonnative plant species, by
dispersing these plant seeds on their hooves and coats as well as
through their digestive tracts, and by fertilizing the disturbed soil
through their feces. Feral pigs feed preferentially on the fruits of
many nonnative plants, such as Passiflora tarminiana (banana poka) and
Psidium cattleianum (strawberry guava), thereby facilitating the spread
of these invasive species, and also contribute to erosion by clearing
vegetation and creating large areas of disturbed soil, especially on
slopes (Aplet et al. 1991, p. 56; Smith 1985, pp. 190, 192, 196, 200,
204, 230-231; Stone 1985, pp. 254-255, 262-264; Medeiros et al. 1986,
pp.
[[Page 11322]]
27-28; Scott et al. 1986, pp. 360-361; Tomich 1986, pp. 120-126;
Cuddihy and Stone 1990, pp. 64-65; Loope et al. 1991, pp. 1-21; Wagner
et al. 1999, p. 52).
Feral pigs are present in the wet forest habitat formerly and
currently inhabited by Phyllostegia hispida within Puu Alii NAR and
Kamakou Preserve, and although control efforts are underway, they
continue to degrade the condition of the forest there (DOFAW 1991, pp.
3, 14-23; TNCH 1994, pp. 6, 9-12; HBMP 2007). They are considered a
major threat to native species and to the overall health of the
watershed in which P. hispida occurs (DOFAW 1991, pp. 3, 14-23; TNCH
1994, pp. 6, 9-12). Significant management actions are directed at
feral ungulate control in the area where P. hispida has been found
within Puu Alii NAR and Kamakou Preserve on Molokai, such as large-
scale watershed fencing, construction of ungulate exclosures around
rare plants, and hunting of feral pigs by both staff and the public
(TNCH 1997a, pp. 2-3; TNCH 1998a, pp. 1-2, 7; DOFAW 2000, pp. 3, 12;
HBMP 2007). When the individual P. hispida was discovered in 1996 next
to the boardwalk at Pepeopae, TNCH noted signs of feral pig presence
(e.g., droppings, evidence of rooting, wallows) in the vicinity (HPMP
2007) and immediately erected a fenced exclosure around the plant to
protect it (TNCH 1997a, pp. 2-3). Similarly, a fenced exclosure was
erected around the individual that was discovered within the Puu Alii
NAR in 1997 to protect it from feral pigs (Nohara 2006). The juvenile
plant discovered within the Puu Alii NAR in 2005 was immediately fenced
to protect it from feral pigs (Stevens 2006), as were four of the most
recently discovered plants along the fenceline within Kamakou Preserve
(Oppenheimer 2007). Most of the wild individuals, however, are not
currently protected within exclosures, and despite ongoing control
efforts, feral pigs persist in the range of P. hispida.
Feral pigs have been described as the most pervasive and disruptive
nonnative influence on the unique native forests of the Hawaiian
Islands, and are widely recognized as one of the greatest current
threats to forest ecosystems in Hawaii (Aplet et al. 1991, p. 56;
Anderson and Stone 1993, p. 195; Loope 1998, pp. 752, 769-770). Feral
pigs continue to persist despite control efforts, and fencing protects
individual plants only temporarily. Furthermore, the remote and rugged
terrain of the islands makes the long-term maintenance of fencing
difficult. Because of their high rate of reproduction, more than 40
percent of the feral pig population must be removed annually before any
decline in numbers is observed (Hess et al. 2006, p. 39). The most
intensive feral pig eradication programs in the Hawaiian Islands have
taken years of continuous effort to achieve effective control, even
within fenced areas (Hess et al. 2006). Even though two peer reviewers
have suggested that the habitat currently occupied by Phyllostegia
hispida on TNCH land has not yet been highly modified by feral pigs,
due to the well-documented negative impacts of feral pigs on native
Hawaiian plant communities, the known habitat degradation caused by
feral pigs in the habitat occupied by P. hispida, and the continuing
presence of feral pigs in the limited area where P. hispida is found,
we consider habitat modification and degradation by feral pigs to be an
immediate and ongoing threat to this species throughout its range, and
we have no indication that this threat is likely to be significantly
ameliorated in the near future.
Nonnative Plants
Introduced, nonnative plant species are a pervasive threat to the
native flora throughout the Hawaiian Islands. Of the current total of
nearly 2,000 native and naturalized plant taxa, approximately half are
introduced, nonnative species from other parts of the world, and nearly
100 of these are considered invasive pest species (Smith 1985, p. 180).
On the Hawaiian Islands and other tropical islands, studies have shown
that many of these introduced plant taxa outcompete and displace native
plants, and often alter the habitat to the point that it is no longer
suitable for the native plant species; these studies include nonnative
pest plants found in habitat similar to that of Phyllostegia hispida
(Smathers and Gardner 1978, pp. 274-275; Smith 1985, pp. 196, 206, 230;
Loope and Medeiros 1992, pp. 7-8; Medeiros et al. 1992, pp. 30-32;
Ellshoff et al. 1995, pp. 1-5; Meyer and Florence 1996, pp. 777-780;
Medeiros et al. 1997, pp. 30-32; Loope et al. 2004, pp. 1472-1473). In
particular, nonnative pest plants may make habitat less suitable for
native plants by modifying availability of light, altering soil-water
regimes, modifying nutrient cycling, or altering fire characteristics
of native plant communities (Smith 1985, pp. 206, 217, 225, 227-233;
Cuddihy and Stone 1990, p. 74).
Although there is no empirical evidence specific to Phyllostegia
hispida due to the lack of research on the species, scientists familiar
with P. hispida believe it does not handle either shade or competition
well (Oppenheimer 2007), and nonnative plants are likely to contribute
to both of these conditions. Examples of some of the nonnative plants
documented in the areas formerly occupied by P. hispida include
Axonopus fissifolius (narrow-leaved carpetgrass), Clidemia hirta
(Koster's curse), Erechtites valerianifolia (fireweed), Juncus effuses
(Japanese mat rush), Rubus rosifolius (thimbleberry), and Sacciolepis
indica (Glenwood grass). Rubus rosifolius and R. argutus are scattered
throughout the area in which P. hispida currently exists, and are
targets of control by TNCH staff in the area (Oppenheimer 2008a).
Because of demonstrated habitat modification and resource competition
by nonnative plant species in habitat similar to the wet forest habitat
of P. hispida, and the ongoing need for control of invasive nonnative
plant species in the area currently occupied by P. hispida, we consider
habitat modification and degradation by nonnative plants to be an
immediate and ongoing threat to this species throughout its range.
To date, successful eradication or control of invasive alien plants
has only been achieved on a very small scale, and then usually when
control efforts have been initiated in the early stages of
establishment (Mack and Lonsdale 2002, p. 166). Many of the invasive,
nonnative plants in Hawaii are so widespread and easily dispersed that
some researchers question whether eradication is a realistic goal
(e.g., Mack and Lonsdale 2002, p. 165). On average, 40 new plant
species have been introduced to the Hawaiian Islands every year over
the past two centuries (Loope 1998, p. 752). Although managers are
attempting to control nonnative plants, resources to support such
efforts are often limited (e.g., Holt 1992, p. 527), and invasive
nonnative plants persist in most areas in spite of such efforts. In
addition, the control of introduced ungulates such as feral pigs, which
contribute to the spread of alien plant species, is viewed as a
prerequisite to the effective control of nonnative plants (e.g., Holt
1992, p. 527). Therefore, due to the ubiquitous nature of the invasive
plant problem in the Hawaiian Islands, the extreme difficulty of
eradicating invasive, nonnative plant species that have become
widespread and well-established, and the continuing presence of
introduced ungulates that contribute to the spread and establishment of
nonnative plants, we have no indication that this threat to
Phyllostegia hispida is likely to be significantly reduced any time in
the near future.
[[Page 11323]]
In summary, feral pigs contribute to the modification and
degradation of Phyllostegia hispida's habitat by disturbing and
destroying vegetative cover, trampling plants and seedlings, reducing
or eliminating plant regeneration by damaging or eating seeds and
seedlings, and increasing erosion by creating large areas of bare soil.
Feral pigs are also a major vector for the dispersal of invasive,
nonnative plant species that pose a threat to P.hispida. The presence
of nonnative plant species contributes to the modification and
degradation of P. hispida's habitat by modifying availability of light,
altering soil-water regimes, modifying nutrient cycling, and changing
the fire characteristics of the native plant community. Evidence
suggests that P. hispida is negatively affected by shade and
competition, both conditions exacerbated by invasive nonnative plants.
We therefore find that habitat modification and degradation by feral
pigs and nonnative plants poses an immediate and ongoing threat to
Phyllostegia hispida, despite the occurrence of the species on
protected lands, and we have no indication that this threat is likely
to be significantly ameliorated in the near future.
B. Overutilization for Commercial, Recreational, Scientific, or
Educational Purposes
Overutilization for commercial, recreational, scientific, or
educational purposes is not known to be a threat to Phyllostegia
hispida in any portion of its range, and as such is not addressed in
this rule.
C. Disease or Predation
Because the native vegetation of Hawaii evolved without any
browsing or grazing mammals present, many plant species do not have
natural defenses against such impacts (Carlquist 1980, pp. 173-175;
Lamoureux 1994, pp. 54-55). Native plants such as Phyllostegia hispida
do not have physical or chemical adaptations, such as thorns or noxious
compounds, to protect them, thereby rendering them particularly
vulnerable to predation by feral pigs or other ungulates (Department of
Geography 1998, pp. 137-138; Carlquist 1980, p. 175). Browsing by
ungulates has been observed on many other native plants, including
common and rare or endangered species (Cuddihy and Stone 1990, pp. 64-
65). In a study of feral pig populations in the Kipahulu Valley on the
island of Maui, feral pigs were observed feeding on at least 40 plant
species in the rainforest ecosystem, 75 percent of which were native
plants occurring in the herbaceous understory and subcanopy layer
(Diong 1982, p. 160). Therefore, even though we have no evidence of
direct browsing for P. hispida, given the presence of feral pigs in the
area where P. hispida occurs, we consider it likely that feral pigs may
affect the species directly through predation. As described above under
Factor A, due to the persistence of feral pigs in the limited range of
P. hispida in spite of control efforts, and the likelihood that their
presence will continue, we believe feral pigs pose an immediate and
ongoing threat to the species throughout its range, and that this
threat is unlikely to be significantly reduced in the near future.
D. The Inadequacy of Existing Regulatory Mechanisms
Of the 238 known individuals of Phyllostegia hispida, 24 wild and
214 recently outplanted, 237 occur on TNCH's Kamakou Preserve. TNCH
manages this private land for the benefit of threatened and endangered
species and ecosystems. The management efforts at TNCH's Kamakou
Preserve include control of nonnative plants and feral pigs, as well as
fencing, all of which benefit P. hispida. However, as noted in the
discussion of Factor A above, the eradication of nonnative plants and
feral pigs, even within fenced areas under active management, is a
difficult and extremely lengthy task. The continuing presence of
nonnative plants and feral pigs within the fenced area of the preserve,
in concert with the threat of very small population size and limited
number of reproductive individuals, which will be discussed in Factor
E, renders P. hispida vulnerable to extinction due to these threats
despite beneficial management on the Kamakou Preserve. The threat of
extinction is not posed, however, by an inadequacy of regulatory
mechanisms on TNCH lands.
Only one known individual of Phyllostegia hispida is found on State
lands, in the Puu Alii NAR. Hawaii Administrative Rules 13-209 provide
protections for this single individual, including a prohibition against
removal, injury, or killing, and a prohibition against the introduction
of plants or animals. The State has been working to fence greater areas
of the NAR and to eradicate feral pigs and nonnative plants within the
fenced areas, but this work is not yet complete. As noted in the
discussion of Factor A above, the eradication of nonnative plants and
feral pigs, even within fenced areas under active management, is a
difficult and extremely lengthy task. Although some regulatory
protections are in place on the NAR that benefit P. hispida, only one
single plant occurs under these protections. This fact, in conjunction
with the persistence of nonnative plants and feral pigs, small
population size, and limited number of reproductive individuals of the
species remaining, renders P. hispida vulnerable to extinction due to
these threats despite the protections on the Puu Alii NAR. The threat
of extinction is not posed, however, by an inadequacy of regulatory
mechanisms on the NAR. The regulatory mechanisms that provide for the
control of threats to P. hispida on the Puu Alii NAR appear to be
adequate, but as the success of these control efforts has yet to be
realized, the threats continue at present.
We find that where individuals of Phyllostegia hispida are
currently found, the inadequacy of regulatory mechanisms does not pose
a threat to the species. However, should the recovery of the species
eventually require reintroductions in other areas, this factor may pose
a potential impediment to recovery.
E. Other Natural or Manmade Factors Affecting Its Continued Existence
One of the most significant threats to Phyllostegia hispida is its
extremely low numbers and highly restricted distribution. A total of
238 plants are currently known to exist, 24 naturally occurring and 214
outplanted. Only two wild individuals are mature and have fruited and
produced seeds. All of the remaining individuals are young or only
recently established. Survivorship of known wild individuals has been
poor, and although outplantings have been attempted, none of these
outplantings has yet proven successful for more than the short term.
Although propagules of P. hispida have been collected on an
opportunistic basis and some controlled propagation of the species has
taken place, there is no dedicated funding for propagation of the
species and no formal plan exists for outplanting and reintroduction.
Deterministic factors, such as habitat alteration or loss of a key
pollinator, may have reduced this population to such a small size that
it is now susceptible to a stochastic extinction event (Gilpin and
Soul[eacute] 1986, pp. 24-25). Species that are known from few wild
individuals and are endemic to a single, small island are inherently
more vulnerable to extinction than widespread species because of the
higher risks posed to a few populations and individuals by genetic
bottlenecks, random demographic fluctuations, and localized
catastrophes, such as hurricanes and disease outbreaks (Mangel and Tier
1994, pp. 607-614;
[[Page 11324]]
Pimm et al. 1988, pp. 757-785). In the case of Phyllostegia hispida,
the entire population of the species is small and restricted to a
highly localized geographic area, rendering it highly vulnerable to the
risk of extinction in the wild due to the lack of redundancy in
populations. In addition, the lack of reproductive individuals and
skewing of the population toward young plants poses a significant
threat to the species, as recruitment may not be sufficient to offset
mortality in the population. These consequences of small population
size (e.g., insufficient natural reproduction, loss of genetic
diversity), in conjunction with the risk of losing the entire
population in the wild due to factors such as localized events (e.g.,
hurricanes) and threats posed by ungulates, render the species highly
vulnerable to extinction at any time. Although some species are
naturally rare, the poor survivorship of P. hispida suggests that the
requisite biological or ecological needs of the species are not being
met under current conditions. The reasons for the poor survivorship and
lack of reproduction observed in this species are not known.
All of these negative demographic factors, as well as the
vulnerability of extinction of the population from a catastrophic
natural event, pose immediate and significant threats to the species
despite the fact that it currently occurs on protected lands, including
State and TNCH reserves. Small population size has therefore become a
primary and immediate threat to this species, and given the current
size and composition of the population, we do not foresee the
likelihood of this threat lessening to any significant degree any time
in the near future.
Conclusion and Determination
We have carefully assessed the best scientific and commercial
information available regarding the past, present, and future threats
to Phyllostegia hispida. The species' extremely low numbers and highly
restricted geographic range make it particularly susceptible to
extinction at any time from random events such as hurricanes (Factor
E). In addition, the lack of mature reproductive individuals poses an
immediate threat to the species (Factor E). Although the species is
found on protected lands with ongoing management efforts, as described
above, we find that it nonetheless faces continuing threats from
habitat destruction and degradation due to feral pig activity and
invasive nonnative plants (Factor A), competition with nonnative plant
species (Factor A), and predation by nonnative mammals (Factor C). The
pervasive nature of feral pigs and invasive plants on the island of
Molokai makes it unlikely that control efforts will significantly
reduce the degree of threat to the species anytime in the near future;
therefore we find that these factors, in combination with the extremely
low number of reproductive individuals and limited distribution of the
population, pose a significant and immediate threat to P. hispida and
place the species at current risk of extinction throughout its range.
The Act defines an endangered species as ``any species which is in
danger of extinction throughout all or a significant portion of its
range.'' Phyllostegia hispida is highly restricted in its range,
currently occurring only within Puu Alii NAR and the immediately
adjacent Kamakou Preserve on the island of Molokai. Based on the
immediate and ongoing significant threats to P. hispida throughout its
entire limited range, as described above, we consider the species P.
hispida to be in danger of extinction throughout all of its range.
Therefore, we are listing P. hispida as an endangered species under the
Act. Because we determine that P. hispida is endangered throughout all
of its range, there is no reason to consider its status in any
significant portion of its range.
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. Recognition through listing results in public awareness and
conservation by Federal, State, and local agencies, private
organizations, and individuals. The Act encourages cooperation with the
States and requires that recovery actions be carried out for all listed
species. The protection measures required of Federal agencies and the
prohibitions against certain activities involving listed plants are
discussed, in part, below.
Section 7(a) of the Act, as amended, requires Federal agencies to
evaluate their actions with respect to any species that is proposed or
listed as endangered or threatened and with respect to its critical
habitat, if any is designated. Regulations implementing this
interagency cooperation provision of the Act are codified at 50 CFR
part 402. Section 7(a)(4) of the Act requires Federal agencies to
confer with the Service on any action that is likely to jeopardize the
continued existence of a species proposed for listing or result in
destruction or adverse modification of proposed critical habitat. If a
species is listed subsequently, section 7(a)(2) of the Act requires
Federal agencies to ensure that activities they authorize, fund, or
carry out are not likely to jeopardize the continued existence of the
species or destroy or adversely modify its critical habitat. If a
Federal action may adversely affect a listed species or its critical
habitat, the responsible Federal agency must enter into formal
consultation with the Service.
For Phyllostegia hispida, Federal agency actions that may require
consultation as described in the preceding paragraph include feral
ungulate removal or other management actions undertaken by the National
Park Service within Puu Alii NAR; the provision of Federal funds to
State and private entities through Federal programs, such as the
Service's Partners for Fish and Wildlife Program, State Wildlife Grant
Program, and Federal Aid in Wildlife Restoration Program; and the
various grants administered by the U.S. Department of Agriculture,
Natural Resources Conservation Service. Other types of actions that may
require consultation include U.S. Army Corps of Engineers activities,
such as the construction or maintenance of boardwalks and bridges
subject to section 404 of the Clean Water Act (33 U.S.C. 1344 et seq.).
The Act and its implementing regulations set forth a series of
general prohibitions and exceptions that apply to endangered plants.
All prohibitions of section 9(a)(2) of the Act, implemented by 50 CFR
17.61, apply. These prohibitions, in part, make it illegal for any
person subject to the jurisdiction of the United States to import or
export, transport in interstate or foreign commerce in the course of a
commercial activity, sell or offer for sale in interstate or foreign
commerce, or remove and reduce to possession the species from areas
under Federal jurisdiction. In addition, for plants listed as
endangered, the Act prohibits the malicious damage or destruction on
areas under Federal jurisdiction and the removal, cutting, digging up,
or damaging or destroying of such plants in knowing violation of any
State law or regulation, including State criminal trespass law. Certain
exceptions to the prohibitions apply to agents of the Service and State
conservation agencies. Although Hawaii has a strong Endangered Species
law (HRS, Sect. 195-D), Phyllostegia hispida is not currently protected
under that law. Federal listing of P. hispida will automatically invoke
State listing under Hawaii's Endangered Species law and
[[Page 11325]]
supplement the protection available under other State laws. The Federal
Endangered Species Act will, therefore, offer additional protection to
this species.
The Act and 50 CFR 17.62 also provide for the issuance of permits
to carry out otherwise prohibited activities involving endangered
plants under certain circumstances. Such permits are available for
scientific purposes and to enhance the propagation or survival of the
species. We anticipate that the only permits that would be sought or
issued for Phyllostegia hispida would be in association with recovery
efforts, as this species is not common in cultivation or the wild.
Requests for copies of the regulations regarding listed species and
inquiries about prohibitions and permits may be addressed to U.S. Fish
and Wildlife Service, Ecological Services, Eastside Federal Complex,

facsimile 503-231-6243).
Critical Habitat
Critical habitat is defined in section 3 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 provisions of
section 4 of 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
protections; and
(2) Specific areas outside the geographical area occupied by a
species at the time it is listed in accordance with the provisions of
section 4 of the Act, upon a determination by the Secretary of the
Interior that such areas are essential for the conservation of the
species.
Conservation, as defined under section 3 of the Act, means to use
and the use of all methods and procedures which are necessary to bring
any endangered or threatened species to the point at which the measures
provided under 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 prohibition against Federal agencies carrying out, funding,
or authorizing the destruction or adverse modification of critical
habitat. Section 7(a)(2) of the Act requires consultation on Federal
actions that may affect 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 does not allow the government or public to access private
lands. Such designation does not require implementation of restoration,
recovery, or enhancement measures by private landowners. Where a
landowner requests Federal agency funding or authorization for an
action that may affect a listed species or critical habitat, the
consultation requirements of section 7(a)(2) of the Act would apply,
but even in the event of a destruction or adverse modification finding,
the landowner's obligation is not to restore or recover the species,
but to implement reasonable and prudent alternatives to avoid
destruction or adverse modification of critical habitat.
For inclusion in a critical habitat designation, the habitat within
the geographical area occupied by the species at the time of listing
must contain the physical and biological features essential to the
conservation of the species, and be included only if those features may
require special management considerations or protection. Critical
habitat designations identify, to the extent known using the best
scientific data available, habitat areas that provide essential life
cycle needs of the species (i.e., areas on which are found the primary
constituent elements (PCEs) laid out in the appropriate quantity and
spatial arrangement for the conservation of the species). Under the
Act, we can designate critical habitat in areas outside the
geographical area occupied by the species at the time it is listed only
when we determine that those areas are essential for the conservation
of the species.
Section 4 of the Act requires that we designate critical habitat on
the basis of the best scientific and commercial data available.
Further, our Policy on Information 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
issued by the Service, 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 developed during the listing process for the species.
Additional information sources may include 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, or other unpublished materials and
expert opinion or personal knowledge.
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 designate critical habitat at
the time a species is determined to be endangered or threatened. Our
regulations (50 CFR 424.12(a)(1)) state that the designation of
critical habitat is not prudent when one or both of the following
situations exist: (1) The species is threatened by taking or other
human activity, and identification of critical habitat can be expected
to increase the degree of threat to the species, or (2) such
designation of critical habitat would not be beneficial to the species.
There is no documentation that Phyllostegia hispida is threatened
by taking or other human activity. In the absence of finding that the
designation of critical habitat would increase threats to a species, if
there are any benefits to a critical habitat designation, then a
prudent finding is warranted. The potential benefits include: (1)
Triggering consultation under section 7 of the Act, for actions in
which there may be a Federal nexus where it would not otherwise occur
because, for example, the area is or has become unoccupied or the
occupancy is in question; (2) focusing conservation activities on the
most essential features and areas; (3) providing educational benefits
to State or county governments or private entities; and (4) preventing
people from causing inadvertent harm to the species.
The primary regulatory effect of a critical habitat designation is
the section 7(a)(2) requirement that Federal agencies refrain from
taking any action that destroys or adversely affects critical habitat.
At present, the only known
[[Page 11326]]
extant individuals of Phyllostegia hispida occur on State and private
land, and all previously known occurrences have been on State and
private lands. However, the State-owned Puu Alii NAR falls within the
boundaries of the Kalaupapa National Historic Park, and the National
Park Service may need to consult with the Service in the future should
they determine that actions they intend to fund, carry out, or
authorize within the NAR may affect P. hispida or destroy or adversely
affect critical habitat. In addition, lands that may be designated as
critical habitat in the future for this species may be subject to
Federal actions that trigger the section 7 consultation requirement,
such as the granting of Federal monies for conservation projects or the
need for Federal permits for projects, such as the construction and
maintenance of boardwalks and bridges subject to section 404 of the
Clean Water Act (33 U.S.C. 1344 et seq.). There may also be some
educational or informational benefits to the designation of critical
habitat. Educational benefits include the notification of land owners,
land managers, and the general public of the importance of protecting
the habitat of this species. In the case of P. hispida, these aspects
of critical habitat designation would potentially benefit the
conservation of the species. Therefore, since we have determined that
the designation of critical habitat will not likely increase the degree
of threat to the species and may provide some measure of benefit, we
find that designation of critical habitat is prudent for P. hispida.
Critical Habitat Determinability
As stated above, section 4(a)(3) of the Act requires the
designation of critical habitat concurrently with the species' listing
``to the maximum extent prudent and determinable.'' Our regulations at
50 CFR 424.12(a)(2) state that critical habitat is not determinable
when one or both of the following situations exist:
(i) Information sufficient to perform required analyses of the
impacts of the designation is lacking, or
(ii) The biological needs of the species are not sufficiently well
known to permit identification of an area as critical habitat.
When critical habitat is not determinable, the Act provides for an
additional year to publish a critical habitat designation (16 U.S.C.
1533(b)(6)(C)(ii)).
In accordance with section 3(5)(A)(i) of the Act and regulations at
50 CFR 424.12, in determining which areas occupied by the species at
the time of listing to designate as critical habitat, we consider those
physical and biological features essential to the conservation of the
species that may require special management considerations or
protection. We consider the physical or biological features to be the
PCEs laid out in the appropriate quantity and spatial arrangement for
the conservation of the species. The PCEs include, but are not limited
to:
(1) Space for individual and population growth and for normal
behavior;
(2) Food, water, air, light, minerals, or other nutritional or
physiological requirements;
(3) Cover or shelter;
(4) Sites for breeding, reproduction, and rearing (or development)
of offspring; and
(5) Habitats that are protected from disturbance or are
representative of the historical geographical and ecological
distributions of a species.
We are currently unable to identify the primary constituent
elements for Phyllostegia hispida, because those physical and
biological features that are essential to the conservation of this
species are not known at this time. As discussed in the ``Species
Information'' section of this rule, between the years 1910 and 1996
only 10 occurrences of P. hispida were documented, and the location
information for these occurrences was recorded at a relatively coarse
scale. Elevations are known only for the few individuals discovered
within the last 10 years. From 1996 through 2005, a total of only 6
plants (3 adults, 2 seedlings, and 1 juvenile) were located, all
existing only as single individuals in disparate locations. All of the
previously known adults died without reproducing naturally in the wild.
Currently, there are 24 individuals known to naturally exist in the
wild, only 2 of which are mature. Seeds and cuttings have been removed
from these two individuals for attempted cultivation (Oppenheimer
2008b). As of April 2008, an additional 214 individuals produced from
cuttings and outplanted into exclosures in Kamakou Preserve are also
extant.
The reasons for the deaths of the Phyllostegia hispida individuals
summarized in the ``Species Information'' section of this rule are
unknown, as are the reasons for poor natural reproduction in the wild.
Key features of the plant's life history, such as longevity, dispersal
mechanisms, or vectors for pollination, are unknown.
With so few recorded occurrences of the species, little is known of
Phyllostegia hispida in terms of what this plant needs to survive and
reproduce successfully in the wild. The poor viability of the P.
hispida occurrences observed in recent years indicates that current
conditions are not sufficient to meet the basic biological requirements
of this species. Although two mature plants that are producing fruits
were recently discovered, there has yet to be an observation of an
individual or population of P. hispida that has successfully produced
surviving young in the wild. As the successful survival and
reproduction of the species in the wild has not yet been documented,
the optimal conditions that would provide the biological or ecological
requisites of the species are not known. Although, as described above,
we can surmise that habitat degradation from a variety of factors has
contributed to the decline of the species, we do not know specifically
what essential physical or biological features of that habitat are
currently lacking for P. hispida. As we are unable to identify the
physical and biological features essential to the conservation of P.
hispida, we are unable to identify areas that contain these features
and that might qualify for designation as critical habitat.
Although we have determined that the designation of critical
habitat is prudent for Phyllostegia hispida, the biological needs of
the species are not sufficiently well known to permit identification of
the physical and biological features that may be essential for the
conservation of the species, or those areas essential to the
conservation of the species. Therefore, we find that critical habitat
for P. hispida is not determinable at this time. The recent outplanting
of more than 200 new seedlings into the Kamakou Preserve presents us
with an opportunity to study the growth of these plants and better
determine the physical and biological features that may be essential
for the conservation of the species. We intend to use the iterative
information gained from this continuing research into the essential
life history requirements of P. hispida to facilitate identification of
essential features and areas. In addition, we will evaluate the needs
of P. hispida within the ecological context of the broader ecosystem in
which it occurs, similar to the approach that was recently proposed for
47 species endemic to the island of Kauai (October 21, 2008; 73 FR
62592), and will consider the utility of using this approach for this
species as well.

Required Determinations
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)
This rule does not contain any new collections of information that
require approval by Office of Management and Budget (OMB) under the
Paperwork Reduction Act. This rule will not impose recordkeeping or
reporting requirements on State or local governments, individuals,
businesses, or organizations. An agency may not conduct or sponsor, and
a person is not required to respond to, a collection of information
unless it displays a currently valid OMB control number.
National Environmental Policy Act
We have determined that environmental assessments and environmental
impact statements, as defined under the authority of the National
Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.), need not be
prepared in connection with regulations adopted under 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).
