Federal and State governments will have taken private property.
Our Response: Chapter VI, Section 4.g. of the DEA and Section 5.e.
of the addendum address costs involved in redistricting lands from the
Agricultural District to the Conservation District. About 3,319 acres
of the intended designation are in the agricultural district, 2,070
acres of which are privately owned. In the event that all of these
lands are redistricted to the conservation district, the loss in land
value would be approximately $18.6 million.
However, as discussed more fully in Chapter VI, Section 4.g. of the
DEA and Section 5.e. of the addendum, agency-initiated and court-
ordered redistricting of some of the privately owned land is reasonably
foreseeable (moderate to high probability). But more to the point, any
redistricting of land to Conservation, and any corresponding loss of
economically beneficial use, would be decided by the LUC and the
courts, not the Service, based on an array of State statutory factors.
As such, the Federal government would not have taken private property.
(58) Comment: Several commenters stated the following: While the
Service has stated that critical habitat affects only activities that
require Federal permits or funding, and does not require landowners to
carry out special management or restrict use of their land, this fails
to address the breadth of Federal activities that affect private
property in Hawaii and the extent to which private landowners are
required to obtain Federal approval before they can use their property.
These requirements also extend to State agencies requiring Federal
funds or approvals.
Our Response: As discussed in Chapter V, Section 2.b. of the DEA,
not every single project, land use, and activity that has a Federal
involvement has historically been subject to section 7 consultation
with the Service (e.g., a federally guaranteed mortgage). Thus, the
analysis was confined to those projects, land uses, and activities that
are, in practice, likely to be subject to consultation. The analysis
based this assessment on a review of past consultations, current
practices, and the professional judgments of Service staff and other
Federal agency staff.
(59) Comment: Several commenters stated the following: The impact
of the proposed designations under State law is potentially more
extensive than under Federal law since the Act contains at least
general criteria for determining when alteration of critical habitat
constitutes ``destruction or adverse modification.'' The lack of
analogous provisions under State law lends itself to a much broader
interpretation of what activities might be considered injurious to the
species (and therefore prohibited). One commenter asked if, to the
extent that the Service has considered the potential interplay between
the Act and State statutes, whether the Service is aware of any
circumstances where similar issues have been raised under other State
conservation statutes when critical habitat was designated. Another
commenter noted, however, that because Hawaii's land use laws are
uniquely onerous, precedent from other States is of little value. The
current wave of proposals to designate critical habitat are the first
time that the Act has been applied to significant areas of private land
in Hawaii. Consequently, even prior experience in Hawaii is of little
relevance.
Our Response: The DEA and the addendum discuss costs resulting from
the interplay of the Endangered Species Act and Hawaii State law in the
sections on Indirect Costs. The uncertainties regarding the occurrence
of many indirect costs and their magnitudes reflect the lack of
extensive experience in Hawaii with critical habitat.
(60) Comment: Several commenters stated the following: The DEA
fails to consider economic impacts of critical habitat that result
through interaction with State law, specifically Hawaii's Environmental
Impact Statement Law. HRS Sec. 343-5 applies to any use of
conservation land, and a full Environmental Impact Statement is
required if any of the significance criteria listed in Hawaii
Administrative Rule 11-200-12 apply. One of these criteria is that an
action is significant if it ``substantially affects a rare, threatened
or endangered species or its habitat.'' This will result in costly
procedural requirements and delays. However, the DEA does not
acknowledge that any impact on endangered species habitat will be
deemed to be ``significant.'' In addition, multiple commenters stated
that the DEA fails to evaluate the practical effect critical habitat
designation will have on development. Special Management Area permits
administered by the City & County of Honolulu, as required by Hawaii's
Coastal Zone Management Act, will be harder to obtain, will result in
delays, will cause a decline in property values, and might make it
impossible to develop. This economic impact disappears because the
DEA's bottom line erroneously counts only so-called ``direct'' costs of
consultation. The Service has taken the position in other States that
it has a right to intervene in local land use proceedings if they
affect endangered species on private property, as evidenced by the
Service's petition to the local zoning board in Arizona to postpone
approval of a rezoning petition pending a survey to determine the
extent to which an endangered plant was present on the property even
though no Federal approval was being sought. That the Service does not
address these activities in the DEA is a fundamental error of the
analysis.
Our Response: Chapter VI, Section 4.h. of the DEA discussed
additional State and county environmental review that would be required
for projects in critical habitat. However, as mentioned in the
addendum, even with the added State and county environmental review,
the intended designation will have little or no practical effect on
residential, resort, commercial, or industrial development because the
analysis anticipates that no such development will occur in the
intended critical habitat. Reasons for this are: (1) Most of the
intended critical habitat is in mountainous areas that are unsuitable
for development due to difficult access and terrain; (2) approximately
96 percent of the intended designation is in the State Conservation
District where existing land-use controls severely limit development;
(3) almost all of the remaining agricultural land in the intended
designation is in areas that are not subject to development pressure
because of steep slopes and little or no nearby infrastructure; (4) the
small amount of land in the urban district (0.6 acre) is on steep
slopes that cannot support development; and (5) all of the land
intended for critical habitat designation that is in the Special
Management Area is also within the conservation district.
(61) Comment: Several commenters stated the following: The DEA
fails to consider economic impacts of critical habitat that result
through interaction with State law, specifically the State Water Code.
HRS Sec. 174C-2 states that ``adequate provision shall be made for
protection of fish and wildlife''. HRS Sec. 174C-71 instructs the
Commission of Water Resource Management to establish an instream use
protection program to protect fish and wildlife. Since landowners might
depend on water pumped from other watersheds, these effects can be far-
reaching. It is impossible to tell from the descriptions in the
proposal whether any water diversions will have to be reduced as a
result of listing and critical habitat designation. It is unfair to
dismiss costly but vital sources of energy and inexpensive irrigation
water while maintaining the highest level of effort to
[[Page 36000]]
protect primary constituent elements for species that do not physically
reside in the area but might somehow be transported. If the critical
habitat proposal would require reducing water diversions from any
stream, the Service should investigate whether that would take anyone's
vested water rights. The Service has an obligation to thoroughly
investigate this issue and refrain from designating critical habitat
until it has determined whether its actions will affect water use. At
minimum, portions of specific parcels that include water sources or
water systems should be removed.
Our Response: Existing irrigation ditch systems and potable water
systems are manmade features that to not contain the primary
constituent elements for the plants. Because the Service does not
include these manmade features in critical habitat designations, the
intended designation will not affect the operation and maintenance of
irrigation and potable water systems (DEA, Chapter II, Section 4).
Regarding new stream diversions, Chapter VI, Section 3.j. of the
DEA stated that it is highly unlikely that new or expanded ditch
systems would be proposed or approved within the proposed designation
because it would directly or indirectly reduce stream flow, which is a
major environmental concern. But if a stream diversion were to be
proposed, critical habitat designation might result in an expanded
biological assessment, project delays, project modifications, and an
increased probability of denial (DEA, Chapter VI, Section 4.f.).
Activities that alter watershed characteristics in ways that would
appreciably reduce groundwater recharge or alter natural, dynamic
wetland or other vegetative communities may directly or indirectly
destroy or adversely modify critical habitat. Such activities may
include water diversion or impoundment, excess groundwater pumping,
manipulation of vegetation such as timber harvesting, residential and
commercial development, and grazing of livestock that degrades
watershed values. However, without more specific information on the
scope and location of a future (and currently unplanned) stream
diversion project, it is not possible to estimate the potential
indirect costs.
(62) Comment: Any water diversion in, or upstream of, critical
habitat will be challenged by people who oppose all diversions on
principle. They will contend that diverting water from endangered
plants risk driving them to extinction. Opponents of diversions could
use the critical habitat designations to invent a colorable argument
sufficient to delay and confuse water use decisions.
Our Response: See the response to the previous comment (61).
(63) Comment: The DEA fails to recognize that the indirect costs to
private landowners to investigate the implications of critical habitat
on their lands are sunk costs associated with the designation process.
Our Response: Chapter VI, Section 4.k. of the DEA indicated that
landowners might want to learn how the designation may affect (1) the
use of their land (either through restrictions or new obligations), and
(2) the value of their land. The cost-estimate to investigate the
implications of critical habitat was $80,000 to $400,000.
Section 5.g of the addendum revised the estimate to reflect the
reduction in the number of potentially affected landowners as a result
of the intended modifications to the critical habitat. The revised
estimate ranges between $26,500 and $227,500. For completeness, the
estimate includes expenditures made during the designation process
(i.e., sunk costs) and expenditures that will be made after the final
designation.
Summary of Changes From the Proposed Rule
Based on a review of public comments received on the proposed
determinations of critical habitat, we have reevaluated our proposed
designations and included several changes to the final designations of
critical habitat. These changes include the following:
(1) We published 303 single species critical habitat units for 99
plant species on the island of Oahu. As proposed, units were identified
for multiple species. Delineation of critical habitat for each
individual species will assist landowners, Federal agencies, and the
Service in focusing and streamlining section 7 consultations.
(2) We changed the scientific names for the following species
associated with the listed species found in the ``SUPPLEMENTARY
INFORMATION: Discussion of the Plant Taxa'' section: Athyrium
sandwichianum changed to Diplazium sandwichianum for Alsinidendron
trinerve, Cyanea acuminata, and Diellia falcata; Athyrium arnottii
changed to Diplazium arnottii for Schiedea kaaclae; Blechnum

lobata var. leptophylla, Nototrichium humile, and Schiedea hookeri;
Lycopodium sp. changed to Lycopodium cernua for Lobelia oahuensis;
Lycopodium cernuum changed to Lycopodium cernua for Platanthera

koolauensis, Hedyotis coriacea, Hedyotis degeneri, Lepidium arbuscula,
Lobelia niihauensis, Platanthera holochila, Sanicula purpurea, Schiedea
hookeri, and Viola chamissoniana ssp. chamissoniana; Thelypteris
cyatheoides changed to Christella cyatheoides in the discussion of
Cyanea crispa; Thelypteris parasitica changed to Christella parasitica
in the discussions of Alectryon macrococcus, Cyanea grimesiana ssp.
obatae, Cyanea truncata, Cyrtandra dentata, Phyllostegia kaalaensis,
Phyllostegia mollis, Phyllostegia parviflora, Pteris lidgatei, Schiedea
kaalae, Schiedea hookeri, and Urera kaalae; Thelypteris sandwicensis
changed to Dryopteris sandwicensis in the discussions of Cyanea
acuminata, Cyrtandra
[[Page 36001]]
subumbellata, and Pteris lidgatei; and Sphenomeris chusana changed to
Sphenomeris chinensis for Pteris lidgatei.
(3) In order to avoid confusion regarding the number of location
occurrences for each species (that do not necessarily each represent a
viable population) and the number of recovery populations (8 to 10 with
100, 300, or 500 reproducing individuals), we changed the word
``population'' to ``occurrence'' where appropriate and updated the
number of occurrences and/or individuals for the following species
found in the ``SUPPLEMENTARY INFORMATION: Discussion of the Plant
Taxa'' section and ``Table 1.--Summary of existing occurrences on Oahu,
and landownership for 101 species reported from Oahu'': Abutilon

(4) We revised the list of excluded, manmade features in the
``Criteria Used to Identify Critical Habitat'' and Sec. 17.99(i) to
include additional features based on information received during the
public comment periods. We added other water system features including
but not limited to pumping stations, irrigation ditches, pipelines,
siphons, tunnels, water tanks, gaging stations, intakes, reservoirs,
diversions, flumes, and wells to aquaducts; existing trails;
campgrounds and their immediate surrounding landscaped area; scenic
lookouts; remote helicopter landing sites; existing fences; towers and
associated structures to telecommunications equipment; other
archaelogical sites to heiaus (indigenous places of worship or
shrines); and electrical power transmission lines and distribution and
communication facilities and regularly maintained associated rights-of-
way and access ways.
(5) We made revisions to the unit boundaries based on information
supplied by commenters, as well as information gained from field visits
to some of the sites, that indicated that the primary constituent
elements were not present in certain portions of the proposed unit,
that certain changes in land use had occurred on lands within the
proposed critical habitat that would preclude those areas from
supporting the primary constituent elements, or that the areas were not
essential to the conservation of the species in question.
(6) Based on information received during the public comment
periods, we updated the elevation ranges in Sec. 17.99(j) ``Plants on
the island of Oahu: Constituent elements''.
(7) All Army lands were excluded under 3(5)(A) and 4(b)(2) of the
Act because we believe the benefit of excluding these lands outweigh
the benefits of including these lands in the final designation (See
``Analysis of Impacts Under Section 4(b)(2): Other Impacts'').
A brief summary of the modifications made to each unit is given
below (see also Figure 1).

kanehoana, Tetramolopium filiforme, Tetramolopium lepidotum ssp.
lepidotum, Urera kaalae, Vigna o-wahuense, and Viola chamissoniana ssp.
chamissoniana.
We excluded the proposed critical habitat on Army lands at Makua
Military Reservation for Alsinidendron obovatum, Diellia falcata,
Dubautia herbstobatae, Flueggea neowawraea, Gouania meyenii, Hedyotis
parvula, Lepidium arbuscula, Lipochaeta tenuifolia, Lobelia
niihauensis, Neraudia angulata, Nototrichium humile, Peucedanum
sandwicense, Schiedea hookeri, Silene lanceolata, Tetramolopium
filiforme, and Viola chamissoniana ssp. chamissoniana and at Schofield
Barracks for Alsinidendron trinerve, Cyanea acuminata, Cyanea
grimesiana ssp. obatae, Gardenia mannii, Labordia cyrtandrae,
Phyllostegia hirsuta, Phyllostegia mollis, Solanum sandwicense,
Stenogyne kanehoana, Tetramolopium filiforme, Urera kaalae, and Viola
chamissoniana ssp. chamissoniana because the benefits of excluding
these areas outweigh the benefits of including these areas as critical
habitat (see ``Analysis of Impacts Under Section 4(b)(2): Other
Impacts'').
In addition, modifications were made to this unit to exclude areas
that do not contain the primary constituent elements of Alectryon
macrococcus, Bonamia menziesii, Cenchrus agrimonioides, Colubrina
oppositifolia, Ctenitis squamigera, Euphorbia haeleeleana, Flueggea
neowawraea, Gouania meyenii, Gouania vitifolia, Hesperomannia
arborescens, Hibiscus brackenridgei, Isodendrion laurifolium,
Isodendrion longifolium, Isodendrion pyrifolium, Lobelia niihauensis,
Phyllostegia mollis, Plantago princeps, Schiedea hookeri, Schiedea
nuttallii, Spermolepis hawaiiensis, and Vigna o-wahuense, all multi-
island species. In order to meet the recovery goal of 8 to 10
populations within the historical range of each of these 21 species,
locations on other islands have been designated as critical habitat
(i.e., locations on Kauai, Molokai, Maui, and/or Kahoolawe), other
locations on Oahu are being designated as critical habitat in this
rule; and/or other locations have been proposed for designation on the
island of Hawaii. In addition, some essential areas were excluded under
4(b)(2) because active management of the area by the landowner
outweighed the benefits of including that area as critical habitat.
Modifications were also made to this unit to exclude areas that do not
contain the primary constituent elements of Abutilon sandwicense,
Alsinidendron obovatum, Chamaesyce herbstii, Cyanea grimesiana ssp.
obatae, Cyanea longiflora, Cyanea superba, Cyrtandra dentata, Delissea
subcordata, Diellia falcata, Gardenia mannii, Hedyotis parvula,
Labordia cyrtandrae, Lepidium arbuscula, Lipochaeta lobata var.
leptophylla, Lipochaeta tenuifolia, Neraudia angulata, Phyllostegia
hirsuta, Schiedea kealiae, Tetramolopium filiforme, and Viola
chamissoniana ssp. chamissoniana, all Oahu-endemic species. In order to
meet the recovery goal of 8 to 10 populations within the historical
range of each of these 20 species, other locations on Oahu are either
being designated as critical habitat in this rule, or areas were
excluded under 4(b)(2) in this rule because active management of the
area by the landowner outweighed the benefits of including that area as
critical habitat.
The area designated as critical habitat for the following 29 Oahu-
endemic species provides habitat within their historical ranges for one
population each of Cyanea acuminata and Eragrostis fosbergii; two
populations of Diellia falcata, Lipochaeta lobata var. leptophylla,
Phyllostegia hirsuta, Schiedea kaalae, Tetramolopium filiforme, and
Urera kaalae; three populations of Cyanea grimesiana ssp. obatae and
Cyrtandra dentata; four populations of Alsinidendron trinerve,
Chamaesyce celastroides var. kaenana, Delissea subcordata, Dubautia
herbstobatae, Hedyotis parvula, Labordia cyrtandrae, Lepidium
arbuscula, Lipochaeta tenuifolia, Sanicula mariversa, and Schiedea
kealiae; five populations of Chamaesyce herbstii, Cyanea longiflora,
and Viola chamissoniana ssp. chamissoniana; six populations of
Alsinidendron obovatum, Cyanea superba, and Neraudia angulata; seven
populations of Abutilon sandwicense; and nine populations of Hedyotis
degeneri and Phyllostegia kaalaensis.
The area designated as critical habitat for the following 33 multi-
island species provides habitat within their historical ranges for one
population each of Alectryon macrococcus, Bonamia menziesii, Centaurium
sebaeoides, Ctenitis squamigera, Cyperus trachysanthos, Diplazium
molokaiense, Eugenia koolauensis, Euphorbia haeleeleana, Flueggea
neowawraea, Gouania meyenii, Hesperomannia arborescens, Isodendrion
pyrifolium, Lobelia niihauensis, Peucedanum sandwicense, Plantago
princeps, Sesbania tomentosa, Silene lanceolata, Solanum sandwicense,
Spermolepis hawaiiensis, and Vigna o-wahuense; three populations of
Colubrina oppositifolia, Hesperomannia arbuscula, Hibiscus
brackenridgei, Isodendrion longifolium, Melicope pallida, and
Tetramolopium lepidotum ssp. lepidotum; four populations of Mariscus
pennatiformis and Schiedea nuttallii; five populations of Cenchrus
agrimonioides, Isodendrion laurifolium, Nototrichium humile, and
Schiedea hookeri; and six populations of Gouania vitifolia.
These modifications resulted in the reduction from 8,503 ha (21,013

Oahu B
This unit was proposed as critical habitat for seven species:
Bonamia menziesii, Euphorbia haeleeleana, Gouania vitifolia, Hibiscus
brackenridgei, Isodendrion pyrifolium, Neraudia angulata, and
Nototrichium humile. We excluded the proposed critical habitat for
Euphorbia haeleeleana, Hibiscus brackenridgei, Isodendrion pyrifolium,
and Nototrichium humile, all multi-island species. This area is not
essential for the conservation of these four species because it lacks
one or more of the primary constituent elements, has a lower proportion
of associated native species than other areas we consider to be
essential to their conservation, and is less likely to contain the
primary constituent elements long-term because it is not currently
managed for conservation of these species. In addition, there are 10
other locations in historical ranges of these four species on Oahu and
other islands that provide habitat for these species and that are
either designated as critical habitat in this rule on Oahu, have been
previously designated on Kauai, Molokai, and/or Maui, are found in
areas on Oahu or other islands that are excluded under 4(b)(2) of the
Act because active management of the area by the landowner outweighed
the benefits of including that area as critical habitat, or have been
proposed for designation on the island of Hawaii.
We excluded the proposed critical habitat for Neraudia angulata, a
species endemic to Oahu. This area is not essential for the
conservation of Neraudia angulata because it lacks one or more of the
primary constituent elements, has a lower proportion of associated
native species than other areas we consider to be essential to the
conservation of N. angulata, and is less likely to contain the primary
constituent elements long-term because it is not currently managed for
conservation of this species. In addition, there are 10 other locations
in its historical range on Oahu that provide habitat for this species
and that are either designated as critical habitat in this rule or are
found in areas excluded under 4(b)(2) of the Act (Makua Military
Reservation) because active management of the unit by the landowner
outweighed the benefits of including it as critical habitat.
The area designated as critical habitat for the following multi-
island species provides habitat within their historical ranges for one
population each of Bonamia menziesii and Gouania vitifolia.
These modifications resulted in the reduction from 34 ha (83 ac) to
23 ha (58 ac). This unit was renamed Oahu 2--Bonamia menziesii--a and
Oahu 2--Gouania vitifolia--a.
Oahu C
This unit was proposed as critical habitat for one species: Bonamia
menziesii, a multi-island species. This area is not essential for the
conservation of Bonamia menziesii because it lacks one or more of the
primary constituent elements, has a lower proportion of associated
native species than other areas we consider to be essential to the
conservation of B. menziesii, and is less likely to contain the primary
constituent elements long-term because it is not currently managed for
conservation of this species. In addition, there are 10 other locations
in its historical range on Oahu and other islands that provide habitat
for this species and that are either designated as critical habitat in
this rule, are found in an area managed for the species on Lanai, have
been designated on Kauai or Maui, or have been proposed for designation
on the island of Hawaii. Exclusion of this area from critical habitat
for Bonamia menziesii resulted in the complete removal of this unit (14
ha (35 ac)) from the final designation.
Oahu D
This unit was proposed as critical habitat for nine species:
Bonamia menziesii, Chamesyce celastroides var. kaenana, Euphorbia
haeleeleana, Gouania vitifolia, Hibiscus brackenridgei, Isodendrion
pyrifolium, Neraudia angulata, Nototrichium humile, and Schiedea
hookeri. We excluded the proposed critical habitat for Hibiscus
brackenridgei and Isodendrion pyrifolium, both multi-island species.
This area is not essential for the conservation of Hibiscus
brackenridgei and Isodendrion pyrifolium because it lacks one or more
of the primary constituent elements, has a lower proportion of
associated native species than other areas we consider to be essential
to the two species' conservation, and is less likely to contain the
primary constituent elements long-term because it is not currently
managed for conservation of these species. In addition, there are 10
[[Page 36005]]
other locations for Isodendrion pyrifolium and at least 9 other
locations for Hibiscus brackenridgei in their historical ranges on Oahu
and other islands that provide habitat for these species and that are
either designated as critical habitat in this rule, are found in an
area managed for the species on Lanai, have been designated on Molokai
and Maui, or have been proposed for designation on the island of
Hawaii.
The area designated as critical habitat for the following Oahu
endemic species provides habitat within their historical ranges for one
population each of Chamesyce celastroides var. kaenana and Neraudia
angulata. The area designated as critical habitat for the following
multi-island species provides habitat within their historical ranges
for one population each of Bonamia menziesii, Euphorbia haeleeleana,
Gouania vitifolia, Nototrichium humile, and Schiedea hookeri.
These modifications resulted in the reduction from 110 ha (271 ac)
to 67 ha (164 ac). This unit was renamed Oahu 3--Bonamia menziesii--b,
Oahu 3--Chamaesyce celastroides var. kaenana--b, Oahu 3--Euphorbia
haeleeleana--a, Oahu 3--Gouania vitifolia--b, Oahu 3--Neraudia
angulata--a, Oahu 3--Nototrichium humile--a, and Oahu 3--Schiedea
hookeri--a.
Oahu E
This unit was proposed as critical habitat for one species:
Chamaesyce kuwaleana. Modifications were made to this unit to exclude
small areas that do not contain the primary constituent elements of C.
kuwaleana. The area designated as critical habitat for C. kuwaleana
provides habitat within its historical range for one population. These
modifications resulted in the slight reduction from 94 ha (38 ac) to 93
ha (37 ac). The unit was renamed Oahu 12--Chamaesyce kuwaleana--c.
Oahu F
This unit was proposed as critical habitat for two species:
Chamaesyce kuwaleana and Isodendrion pyrifolium. We excluded the
proposed critical habitat for I. pyrifolium, a multi-island species.
This area is not essential for the conservation of this species because
it lacks one or more of the primary constituent elements, has a lower
proportion of associated native species than other areas we consider to
be essential to the conservation of Isodendrion pyrifolium, and is less
likely to contain the primary constituent elements long-term because it
is not currently managed for conservation of this species. In addition,
there are 10 other locations in its historical range on Oahu and other
islands that provide habitat for this species and that are either
designated as critical habitat in this rule, are found in an area
managed for the species on Lanai, have been designated on Molokai and
Maui, or have been proposed for designation on the island of Hawaii.
The area designated as critical habitat for Chamaesyce kuwaleana
provides habitat within its historical range for one population. This
modification resulted in the reduction from 81 ha (200 ac) to 53 ha
(131 ac). This unit was renamed Oahu 11--Chamaesyce kuwaleana--b.
Oahu G
This unit was proposed as critical habitat for two species:
Tetramolopium filiforme and Viola chamissoniana ssp. chamissoniana. We
excluded the proposed critical habitat for Tetramolopium filiforme on
Army lands at Schofield Barracks because the benefits of excluding this
area outweigh the benefits of including this area (see ``Analysis of
Impacts Under Section 4(b)(2): Other Impacts''). The area designated as
critical habitat for Viola chamissoniana ssp. chamissoniana provides
habitat within its historical range for one population. This
modification resulted in the reduction from 16 ha (40 ac) to 6 ha (15
ac). This unit was renamed Oahu 10--Viola chamissoniana ssp.
chamissoniana--d.
Oahu H
This unit was proposed as critical habitat for Chamaesyce
kuwaleana. The area designated as critical habitat for Chamaesyce
kuwaleana provides habitat within its historical range for one
population. No modifications were made to the acreage of this unit,
which was renamed Oahu 9--Chamaesyce kuwaleana--a.
Oahu I
This unit was proposed as critical habitat for 42 species: Abutilon
sandwicense, Alectryon macrococcus, Alsinidendron obovatum, Bonamia
menziesii, Cenchrus agrimonioides, Chamaesyce herbstii, Chamaesyce
kuwaleana, Cyanea grimesiana ssp. obatae, Cyanea pinnatifida, Cyrtandra
dentata, Delissea subcordata, Diellia falcata, Diellia unisora,
Flueggea neowawraea, Gardenia mannii, Gouania meyenii, Hedyotis
coriacea, Hedyotis parvula, Hesperomannia arbuscula, Hibiscus
brackenridgei, Isodendrion pyrifolium, Lepidium arbuscula, Lipochaeta
lobata var. leptophylla, Lobelia niihauensis, Melicope pallida,
Melicope saint-johnii, Neraudia angulata, Phyllostegia hirsuta,
Phyllostegia kaalaensis, Phyllostegia mollis, Phyllostegia parviflora,
Plantago princeps, Sanicula mariversa, Schiedea hookeri, Schiedea
kaalae, Schiedea nuttallii, Silene perlmanii, Solanum sandwicense,
Stenogyne kanehoana, Tetramolopium lepidotum ssp. lepidotum, Urera
kaalae, and Viola chamissoniana ssp. chamissoniana. We excluded the
proposed critical habitat on Army lands at Schofield Barracks for
Cyanea grimesiana ssp. obatae, Gardenia mannii, Phyllostegia hirsuta,
Phyllostegia mollis, Solanum sandwicense, Stenogyne kanehoana, Urera
kaalae, and Viola chamissoniana ssp. chamissoniana because the benefits
of excluding this area outweigh the benefits of including this area
(see ``Analysis of Impacts Under Section 4(b)(2): Other Impacts''). We
also excluded the proposed critical habitat for Cyrtandra dentata,
Flueggea neowawraea, and Hibiscus brackenridgei. This area is not
essential for the conservation of these three species because it lacks
one or more of the primary constituent elements, has a lower proportion
of associated native species than other areas we consider to be
essential to the conservation of these three species, and is less
likely to contain the primary constituent elements long-term because it
is not currently managed for conservation of these species. In
addition, there are at least 8 other locations for Cyrtandra dentata,
and at least 10 other locations for Flueggea neowawraea and Hibiscus
brackenridgei, in their historical ranges on Oahu and other islands
that provide habitat for these species and that are either designated
as critical habitat in this rule; are found on lands managed for the
species on Lanai or Oahu's Army lands; have been designated on Kauai,
Molokai, and Maui; or have been proposed for designation on the island
of Hawaii.
Modifications were made to this unit to exclude areas that do not
contain the primary constituent elements for Alectryon macrococcus,
Bonamia menziesii, Cenchrus agrimonioides, and Tetramolopium lepidotum
ssp. lepidotum, all multi-island species. In order to meet the recovery
goal of 8 to 10 populations within the historical range of each of
these 21 species, other locations either have been designated as
critical habitat on Kauai, Molokai, Maui, and/or Kahoolawe; were
excluded under 4(b)(2) on one or more of the Hawaiian islands because
active management of an area by the landowner outweighed the benefits
of including that area as critical habitat;
[[Page 36006]]
are being designated as critical habitat in this rule; and/or have been
proposed for designation on the island of Hawaii. Modifications were
also made to this unit to exclude areas that do not contain the primary
constituent elements for Abutilon sandwicense, Chamaesyce herbstii,
Cyanea pinnatifida, Diellia falcata, Diellia unisora, Melicope saint-
johnii, Neraudia angulata, Phyllostegia hirsuta, and Urera kaalae, all
Oahu-endemic species. In order to meet the recovery goal of 8 to 10
populations within the historical range of each of these 20 species,
other locations on Oahu are either being designated as critical habitat
in this rule or were excluded under 4(b)(2) in this rule because active
management of an area by the landowner outweighed the benefits of
including that area as critical habitat.
The area designated as critical habitat for the following 24 Oahu-
endemic species provides habitat within their historical ranges for one
population each of Alsinidendron obovatum, Neraudia angulata, and
Phyllostegia kaalaensis; two populations each of Chamaesyce herbstii,
Chamaesyce kuwaleana, Gardenia mannii, Gouania meyenii, Sanicula
mariversa, and Viola chamissoniana ssp. chamissoniana; three
populations each of Abutilon sandwicense, Cyanea grimesiana ssp.
obatae, Hedyotis parvula, Lepidium arbuscula, Melicope saint-johnii,
Phyllostegia hirsuta, and Stenogyne kanehoana; four populations each of
Cyanea pinnatifida, Delissea subcordata, Schiedea kaalae, and Urera
kaalae; six populations each of Diellia unisora and Silene perlmanii;
seven populations of Diellia falcata; and eight populations of
Lipochaeta lobata var. leptophylla.
The area designated as critical habitat for the following 15 multi-
island species provides habitat within their historical ranges for one
population each of Alectryon macrococcus, Bonamia menziesii, Hedyotis
coriacea, Lobelia niihauensis, and Plantago princeps; two populations
each of Hesperomannia arbuscula, Isodendrion pyrifolium, Schiedea
hookeri, Schiedea nuttallii, and Solanum sandwicense; three populations
each of Cenchrus agrimonioides, Melicope pallida, Phyllostegia mollis,
and Phyllostegia parviflora; and five populations of Tetramolopium
lepidotum ssp. lepidotum.
This modification resulted in the reduction from 5,109 ha (12,623
ac) to 1,917 ha (4,736 ac). This unit was renamed Oahu 15--Abutilon

This unit was proposed as critical habitat for Marsilea villosa.
The area designated as critical habitat for Marsilea villosa provides
habitat within its historical range for one population. No
modifications were made to the acreage of this unit, which was renamed
Oahu 13--Marsilea villosa--a.
Oahu K
This unit was proposed as critical habitat for Marsilea villosa.

Oahu L
This unit was proposed as critical habitat for 45 species:
Adenophorus periens, Bonamia menziesii, Chamaesyce celastroides var.
kaenana, Chamaesyce deppeana, Chamaesyce rockii, Cyanea acuminata,
Cyanea crispa, Cyanea grimesiana ssp. grimesiana, Cyanea humboltiana,
Cyanea koolauensis, Cyanea longiflora, Cyanea st.-johnii, Cyanea
superba, Cyanea truncata, Cyrtandra dentata, Cyrtandra polyantha,
Cyrtandra subumbellata, Cyrtandra viridiflora, Delissea subcordata,
Diellia erecta, Eugenia koolauensis, Gardenia mannii, Hedyotis
coriacea, Hesperomannia arborescens, Isodendrion laurifolium,
Isodendrion longifolium, Labordia cyrtandrae, Lobelia gaudichaudii ssp.
koolauensis, Lobelia monostachya, Lobelia oahuensis, Lysimachia
filifolia, Melicope lydgatei, Myrsine juddii, Phlegmariurus nutans,
Phyllostegia hirsuta, Phyllostegia parviflora, Plantago princeps,
Platanthera holochila, Pteris lidgatei, Sanicula purpurea, Schiedea
kaalae, Solanum sandwicense, Tetraplasandra gymnocarpa, Trematolobelia
singularis, and Viola oahuensis. We excluded the proposed critical
habitat on Army lands
[[Page 36007]]
at Schofield Barracks East Range for Cyanea acuminata, Cyrtandra
viridiflora, Gardenia mannii, Hesperomannia arborescens, Myrsine
juddii, Phlegmariurus nutans, and Viola oahuensis; at Kahuku Training
Area for Cyanea longiflora and Eugenia koolauensis; and at Kawailoa
Training Area for Cyanea acuminata, Cyanea crispa, Cyanea grimesiana
ssp. grimesiana, Cyanea humboltiana, Cyanea koolauensis, Cyanea
longiflora, Cyanea st.-johnii, Cyrtandra dentata, Cyrtandra
viridiflora, Gardenia mannii, Hesperomannia arborescens, Labordia

Myrsine juddii, Phlegmariurus nutans, Phyllostegia hirsuta, Pteris
lidgatei, Sanicula purpurea, Tetraplasandra gymnocarpa, and Viola
oahuensis because the benefits of excluding this area outweigh the
benefits of including this area (see ``Analysis of Impacts Under
Section 4(b)(2): Other Impacts''). We excluded the proposed critical
habitat for Solanum sandwicense, a multi-island species. This area is
not essential for the conservation of this species, because it lacks
one or more of the primary constituent elements, has a lower proportion
of associated native species than other areas we consider to be
essential to the conservation of S. sandwicense, and is less likely to
contain the primary constituent elements long-term because it is not
currently managed for conservation of this species. In addition, there
are 10 other locations in its historical range on Oahu and Kauai that
provide habitat for this species, which are either designated as
critical habitat in this rule, in an area excluded under 4(b)(2) of the
Act because active management of the area by the landowner outweighed
the benefits of including that area as critical habitat (Schofield
Barracks), or have been designated on Kauai.
Modifications were made to this unit to exclude areas that do not
contain the primary constituent elements essential to the conservation
of Adenophorus periens, Bonamia menziesii, Cyanea grimesiana ssp.
grimesiana, Diellia erecta, Eugenia koolauensis, and Hesperomannia
arborescens, all multi-island species. In order to meet the recovery
goal of 8 to 10 populations within the historical range of each of
these six species, other locations either have been designated as
critical habitat on Kauai, Molokai, Maui, and/or Kahoolawe; were
excluded under 4(b)(2) on Oahu, Lanai, and Maui because active
management of an area by the landowner outweighed the benefits of
including that area as critical habitat; are being designated as
critical habitat in this rule; and/or have been proposed for
designation on the island of Hawaii. Modifications were also made to
this unit to exclude areas that do not contain the primary constituent
elements essential to the conservation of Chamaesyce rockii, Cyanea
acuminata, Cyanea crispa, Cyanea humboltiana, Cyanea koolauensis,
Cyanea longiflora, Cyanea st.-johnii, Cyanea truncata, Cyrtandra
polyantha, Cyrtandra subumbellata, Cyrtandra viridiflora, Delissea
subcordata, Gardenia mannii, Labordia cyrtandrae, Lobelia monostachya,
Lobelia oahuensis, Melicope lydgatei, Phyllostegia hirsuta, and Viola
oahuensis, all island-endemic species. In order to meet the recovery
goal of 8 to 10 populations within the historical range of each of
these 19 species, other locations on Oahu are either being designated
as critical habitat in this rule or were excluded under 4(b)(2) in this
rule because active management of an area by the landowner outweighed
the benefits of including that area as critical habitat.
The area designated as critical habitat for the following 27 Oahu-
endemic species provides habitat within their historical ranges for two
populations each of Chamaesyce celastroides var. kaenana, Chamaesyce
deppeana, Cyanea superba, Delissea subcordata, Gardenia mannii, and
Phyllostegia hirsuta; three populations each of Cyanea longiflora, and
Schiedea kaalae; four populations of Cyanea acuminata; five populations
each of Chamaesyce rockii, Cyrtandra polyantha, and Cyrtandra
viridiflora; six populations each of Labordia cyrtandrae, Melicope
lydgatei, Myrsine juddii, and Trematolobelia singularis; seven
populations each of Cyanea crispa, Cyanea koolauensis, Cyrtandra
subumbellata, Lobelia gaudichaudii ssp. koolauensis, Lobelia
monostachya, and Tetraplasandra gymnocarpa; eight populations of Cyanea
humboltiana; nine populations each of Cyanea st.-johnii and Cyanea
truncata; and 10 populations each of Lobelia oahuensis and Viola
oahuensis.
The area designated as critical habitat for the following 16 multi-
island species provides habitat within their historical ranges for one
population each of Adenophorus periens, Bonamia menziesii, Diellia
erecta, Hedyotis coriacea, Isodendrion laurifolium, Isodendrion
longifolium, and Plantago princeps; two populations each of
Hesperomannia orborescens and Platanthera holochila; three populations
each of Cyanea grimesiana ssp. grimesiana and Pteris lidgatei; four
populations each of Eugenia koolauensis and Sanicula puprurea; five
populations of Phlegmariurus nutans; and six populations each of
Lysimachia filifolia and Phyllostegia parviflora.
This modification resulted in the reduction from 30,068 ha (74,301

Oahu M
This unit was proposed as critical habitat for Sesbania tomentosa.
We excluded the proposed critical habitat for this multi-island
species. This area is not essential for the conservation of S.
tomentosa because it lacks one or more of the primary constituent
elements, has a lower proportion of associated native species than
other areas we consider to be essential to the conservation of S.
tomentosa, and is less likely to contain the primary constituent
elements long-term because it is not currently managed for conservation
of this species. In addition, there are at least 10 other locations in
its historical range on Oahu and other islands that provide habitat for
this species, which are either designated as critical habitat in this
rule; have been designated on Kauai, Molokai, Maui, and the
Northwestern Hawaiian Islands; or have been proposed for designation on
the island of Hawaii. Exclusion of this unit from critical habitat for
Sesbania tomentosa resulted in the removal of this 100 ha (246 ac) unit
from the final designation.
Oahu N
This unit was proposed as critical habitat for two species:
Centaurium sebaeoides and Sesbania tomentosa. We excluded the proposed
critical habitat for Centaurium sebaeoides, a multi-island species.
This area is not essential for the conservation of this species because
it lacks one or more of the primary constituent elements, has a lower
proportion of associated native species than other areas we consider to
be essential to the conservation of C. sebaeoides, and is less likely
to contain the primary constituent elements long-term because it is not
currently managed for conservation of this species. In addition, there
are at least 10 other locations in its historical range on Oahu and
other islands that provide habitat for this species, which are either
designated as critical habitat in this rule; have been designated on
Kauai, Molokai, and Maui; or are found in an area managed for the
species on Lanai. The area designated as critical habitat for Sesbania
tomentosa provides habitat within its historical range for one
population. The exclusion of Centaurium sebaeoides did not result in a
change to the acreage of this unit, which was renamed Oahu 18--Sesbania
tomentosa--b.
Oahu O
This unit was proposed as critical habitat for three species:
Cyanea crispa, Cyanea truncata, and Schiedea kaalae. Modifications were
made to this unit to exclude areas that do not contain the primary
constituent elements essential to the conservation of Cyanea crispa and
Cyanea truncata, both endemic to Oahu. The area designated as critical
habitat for the three Oahu-endemic species provides habitat within
their historical ranges for one population each of Cyanea crispa,
Cyanea truncata, and Schiedea kaalae. In order to meet the recovery
goal of 8 to 10 populations within the historical range of each of
these three species, other locations on Oahu are being designated as
critical habitat in this rule. Modifications to this unit resulted in
the reduction from 431 ha (1,066 ac) to 312 ha (772 ac). This unit was
renamed Oahu 21--Cyanea crispa--c, Oahu 21--Cyanea truncata--b, and
Oahu 21--Schiedea kaalae--f.
Oahu P
This unit was proposed as critical habitat for Sesbania tomentosa.
We excluded the proposed critical habitat for this multi-island
species. This area is not essential for the conservation of S.
tomentosa because it lacks one or more of the primary constituent
elements, has a lower proportion of associated native species than
other areas we consider to be essential to the conservation of Sesbania
tomentosa, and is less likely to contain the primary constituent
elements long-term because it is not currently managed for conservation
of this species. In addition, there are at least 10 other locations in
its historical range on Oahu and other islands that provide habitat for
this species which are either designated as critical habitat in this
rule; have been designated on Kauai, Molokai, and Maui, and the
Northwestern Hawaiian Islands; or have been proposed for designation on
the island of Hawaii. Exclusion of this unit from critical habitat for
Sesbania tomentosa resulted in the removal of this entire unit (2 ha (3
ac)) from the final designation.
Oahu Q
This unit was proposed as critical habitat for two species:
Chamaesyce kuwaleana and Sesbania tomentosa. We excluded the proposed
critical habitat for Sesbania tomentosa, a multi-island species. This
area is not essential for the conservation of this species because it
lacks one or more of the primary constituent elements, has a lower
proportion of associated native species than other areas we consider to
be essential to the conservation of S. tomentosa, and is less likely to
contain the primary constituent elements long-term because it is not
currently managed for conservation of this species. In addition, there
are at least 10 other locations in its historical range on Oahu and
other islands that provide habitat for this species, which are either
designated as critical habitat in this rule; have been designated on
Kauai, Molokai, and Maui, and the Northwestern Hawaiian Islands; or
have been proposed for designation on the island of Hawaii. The area
designated as critical habitat for the Oahu-endemic, Chamaesyce
kuwaleana, provides habitat within its historical range for one
population. No modifications were made to the acreage of this unit,
which was renamed Oahu 22--Chamaesyce kuwaleana--e.

[[Page 36009]]
habitat within its historical range for one population. No
modifications were made to the acreage of this unit, which was renamed
Oahu 23--Chamaesyce kuwaleana--f.
Oahu S
This unit was proposed as critical habitat for two species:
Sesbania tomentosa and Vigna o-wahuensis. We excluded the proposed
critical habitat for Sesbania tomentosa, a multi-island species. This
area is not essential for the conservation of this species because it
lacks one or more of the primary constituent elements, has a lower
proportion of associated native species than other areas we consider to
be essential to the conservation of S. tomentosa, and is less likely to
contain the primary constituent elements long-term because it is not

Oahu U
This unit was proposed as critical habitat for three species:
Chamaesyce kuwaleana, Sesbania tomentosa, and Vigna o-wahuense. We
excluded the proposed critical habitat for Sesbania tomentosa, a multi-
island species. This area is not essential for the conservation of this
species because it lacks one or more of the primary constituent

its historical range on Oahu and other islands that provide habitat for
this species which are either designated as critical habitat in this
rule; have been designated on Kauai, Molokai, and Maui, and the
Northwestern Hawaiian Islands; or have been proposed for designation on
the island of Hawaii. The area designated as critical habitat for the
multi-island species, Vigna o-wahuensis, and Oahu endemic, Chamaesyce
kuwaleana, provides habitat within their historical ranges for one
population of each. No modifications were made to the acreage of this
unit, which was renamed Oahu 26--Chamaesyce kuwaleana--g and Oahu 26--
Vigna o-wahuensis--d.
Oahu V
This unit was proposed as critical habitat for one species:
Sesbania tomentosa. We excluded the proposed critical habitat for
Sesbania tomentosa, a multi-island species. This area is not essential
for the conservation of this species because it lacks one or more of
the primary constituent elements, has a lower proportion of associated
native species than other areas we consider to be essential to the
conservation of S. tomentosa, and is less likely to contain the primary
constituent elements long-term because it is not currently managed for
conservation of this species. In addition, there are at least 10 other
locations in its historical range on Oahu and other islands that
provide habitat for this species which are either designated as
critical habitat in this rule; have been designated on Kauai, Molokai,
and Maui, and the Northwestern Hawaiian Islands; or have been proposed
for designation on the island of Hawaii. Exclusion of this unit from
critical habitat for Sesbania tomentosa resulted in the removal of this
entire unit (4 ha (10 ac)) from the final designation.
Oahu W
This unit was proposed as critical habitat for three species:
Centaurium sebaeoides, Cyperus trachysanthos, and Marsilea villosa.
Modifications were made to this unit to exclude areas that do not
contain the primary constituent elements essential to the conservation
of Centaurium sebaeoides, a multi-island species. The area designated
as critical habitat for the three multi-island species, Centaurium
sebaeoides, Cyperus trachysanthos, and Marsilea villosa, provides
habitat within their historical ranges for one population of each.
Modifications to this unit resulted in the reduction from 340 ha (840
ac) to 43 ha (106 ac). This unit was renamed Oahu 27--Centaurium
sebaeoides--b, Oahu 28--Cyperus trachysanthos--b, Oahu 29--Cyperus
trachysnthos--c, Oahu 28--Marsilea villosa--c, and Oahu 29--Marsilea
villosa--d.
Oahu X1
This unit was proposed as critical habitat for two multi-island
species: Gouania meyenii and Spermolepis hawaiiensis. Modifications
were made to this unit to exclude areas that do not contain the primary
constituent elements essential to the conservation of Gouania meyenii
and Spermolepis hawaiiensis. The area designated as critical habitat
for Gouania meyenii and Spermolepis hawaiiensis provides habitat within
their historical ranges for one population of each. These modifications
resulted in the reduction from 117 ha (290 ac) to 116 ha (286 ac). This
unit was renamed Oahu 31--Gouania meyenii--d and Oahu 31--Spermolepis
hawaiiensis--b.
Oahu X2
This unit was proposed as critical habitat for two multi-island
species: Cyperus trachysanthos and Marsilea villosa. Modifications were
made to this unit to exclude small areas that do not contain the
primary constituent elements essential to the conservation of Cyperus
trachysanthos and Marsilea villosa. The area designated as critical
habitat for Cyperus trachysanthos and Marsilea villosa provides habitat
within their historical ranges for one population of each. This
modification resulted in the reduction from 8 ha (21 ac) to 6 ha (15
ac). This unit was renamed Oahu 36--Cyperus trachysanthos--d and Oahu
36--Marsilea villosa--e.

Critical Habitat
Critical habitat is defined in section 3 of the Act as--(i) the
specific areas within the geographic area occupied by a species, at the
time it is listed in accordance with the Act, on which are found those
physical or biological features (I) essential to the conservation of
the species and (II) that may require special management considerations
or protection; and, (ii) specific areas outside the geographic area
occupied by a species at the time it is listed, upon a determination
that such areas are essential for the conservation of the species.
``Conservation,'' as defined by the Act, means the use of all methods
and procedures that are necessary to bring an endangered or a
threatened species to the point at which listing under the Act is no
longer necessary.
Critical habitat receives protection under section 7 of the Act
through the prohibition against destruction or adverse modification of
critical habitat with regard to actions carried out, funded, or
authorized by a Federal agency. Section 7 also requires conferences on
Federal actions that are likely to result in the destruction or adverse
modification of proposed critical habitat. In our regulations at 50 CFR
402.02, we define destruction or adverse modification as ``* * * a
direct or indirect alteration that appreciably diminishes the value of
critical habitat for both the survival and recovery of a listed
species. Such alterations include, but are not limited to, alterations
adversely modifying any of those physical or biological features that
were the basis for determining the habitat to be critical.'' The
relationship between a species' survival and its recovery has been a
source of confusion for some in the past. We believe that a species'
ability to recover depends on its ability to survive into the future
when its recovery can be achieved; thus, the concepts of long-term
survival and recovery are intricately linked. However, in the March 15,
2001, decision of the United States Court of Appeals for the Fifth
Circuit (Sierra Club v. Fish and Wildlife Service et al., 245 F.3d 434)
regarding a not prudent finding, the court found our definition of
destruction or adverse modification as currently contained in 50 CFR
402.02 to be invalid. In response to this decision, we are reviewing
the regulatory definition of adverse modification in relation to the
conservation of species.
In order to be included in a critical habitat designation, areas
within the geographical range of the species at the time of listing
must contain the physical or biological features essential to the
conservation of the species or, for an area outside the geographical
area occupied by the species at the time of listing, the area itself
must be essential to the conservation of the species (16 U.S.C.
1532(5)(A)).
Section 4 requires that we designate critical habitat for a
species, to the extent such habitat is determinable, at the time of
listing. When we designate critical habitat at the time of listing or
under short court-ordered deadlines, we may not have sufficient
information to identify all the areas essential for the conservation of
the species, or we may inadvertently include areas that later will be
shown to be nonessential. Nevertheless, we are required to designate
those areas we know to be critical habitat, using the best information
available to us.
Within the geographic areas occupied by the species, we will
designate only areas that have features and habitat characteristics
that are necessary to sustain the species. If the information available
at the time of designation does not show that an area provides
essential life cycle needs of the species, then the area should not be
included in the critical habitat designation.
Our regulations state that ``The Secretary shall designate as
critical habitat areas outside the geographical area presently occupied
by a species only when a designation limited to its present range would
be inadequate to ensure the conservation of the species' (50 CFR
424.12(e)). Accordingly, when the best available scientific and
commercial data do not demonstrate that the conservation needs of the
species require designation of critical habitat outside of occupied
areas, we will not designate critical habitat in areas outside the
geographic area occupied by the species.
Our Policy on Information Standards Under the Endangered Species
Act, published in the Federal Register on July 1, 1994 (59 FR 34271),
provides criteria, establishes procedures, and provides guidance to
ensure that our decisions represent the best scientific and commercial
data available. It requires our biologists, to the extent consistent
with the Act and with the use of the best scientific and commercial
data available, to use primary and original sources of information as
the basis for recommendations to designate critical habitat. When
determining which areas are critical habitat, a primary source of
information should be the listing package for the species. Additional
information may be obtained from recovery plans, articles in peer-
reviewed journals, conservation plans developed by States and counties,
scientific status surveys and studies, and biological assessments or
other unpublished materials.
It is important to clearly understand that critical habitat
designations do not signal that habitat outside the designation is
unimportant or may not be required for recovery. Areas outside the
critical habitat designation will continue to be subject to
conservation actions that may be implemented under section 7(a)(1) and
to the regulatory protections afforded by the Act's 7(a)(2) jeopardy
standard and section 9 prohibitions, as determined on the basis of the
best available information at the time of the action. We specifically
anticipate that federally funded or assisted projects affecting listed
species outside their designated critical habitat areas may still
result in jeopardy findings in some cases. Similarly, critical habitat
designations made on the basis of the best available information at the
time of designation will not control the direction and substance of
future recovery plans, habitat conservation plans, or other species
conservation planning efforts if new information available to these
planning efforts calls for a different outcome. Furthermore, we
recognize that designation of critical habitat may not include all of
the habitat areas that may be determined to be necessary for the
recovery of the species.
A. Prudency
Designation of critical habitat is not prudent when one or both of
the following situations exist: (i) The species is threatened by taking
or other human activity, and identification of critical habitat can be
expected to increase the degree of such threat to the species; or (ii)
such designation of critical habitat would not be beneficial to the
species (50 CFR 424.12(a)(1)).
To determine whether critical habitat would be prudent for each
species, we analyzed the potential threats and benefits for each
species in accordance with the court's order. One species, Cyrtandra
crenata, a Oahu endemic species, is no longer extant in the wild.
Cyrtandra crenata was last seen in the wild in 1947 (HINHP Database
2001). In addition, this species is not known to be in storage or under
propagation. Under these circumstances, we have determined that
designation of critical habitat for Cyrtandra crenata is not prudent
because such designation would be of no benefit to this species. If
this species is relocated, we may revise this final determination to
incorporate or address new information
[[Page 36011]]
as it becomes available (See 16 U.S.C. 1532(5)(B); 50 CFR 424.13(f)).
Due to low numbers of individuals and/or populations and their
inherent immobility, the other 100 plant species could be vulnerable to
unrestricted collection, vandalism, or disturbance. We examined the
evidence currently available for each of these species and found
specific evidence of vandalism, disturbance, and/or the threat of
unrestricted collection for one species of Pritchardia, the native
palm. At the time of listing, we determined that designation of
critical habitat was not prudent for Pritchardia kaalae because it
would increase the degree of threat from vandalism or collecting and
would provide no benefit (61 FR 53108). Since then, we have received
information on the commercial trade in palms conducted through the
Internet (Grant Canterbury, Service, in litt. 2000). Several nurseries
advertise and sell seedlings and young plants, including 13 species of
Hawaiian Pritchardia. Seven of these species are federally protected,
including Pritchardia kaalae. In light of this information, we believe
that designation of critical habitat would likely increase the threat
from vandalism or collection to this species of Pritchardia on Oahu.
These plants are easy to identify, and they are attractive to
collectors of rare palms, either for their personal use or to trade or
sell for personal gain (Johnson 1996). We believe that the evidence
shows that Pritchardia kaalae may be attractive to such collectors. The
final listing rule for this species contained only general information
on its distribution, but the publication of precise maps and
descriptions of critical habitat in the Federal Register would make
Pritchardia kaalae more vulnerable to incidents of vandalism or
collection and, therefore, contribute to its decline and make recovery
more difficult (61 FR 53089).
For Pritchardia kaalae, we believe that the benefits of designating
critical habitat do not outweigh the potential increased threats from
vandalism or collection. Given all of the above considerations, we
determine that designation of critical habitat for Pritchardia kaalae
is not prudent.
In the final rule designating critical habitat for plants on Lanai,
published on January 9, 2003 (68 FR 1220), we explained why we believe
that critical habitat was prudent for the following 17 multi-island
species that also occur on Oahu: Adenophorus periens, Bonamia
menziesii, Cenchrus agrimonioides, Centaurium sebaeoides, Ctenitis
squamigera, Cyanea grimesiana ssp. grimesiana, Cyperus trachysanthos,
Diellia erecta, Diplazium molokaiense, Hesperomannia arborescens,
Hibiscus brackenridgei, Isodendrion pyrifolium, Sesbania tomentosa,
Silene lanceolata, Spermolepis hawaiiensis, Tetramolopium lepidotum
ssp. lepidotum, and Vigna o-wahuensis. In the final rule designating
critical habitat for plants on Kauai and Niihau, published on February
27, 2003 (68 FR 9116), we explained why that critical habitat was
prudent for the following 16 multi-island species that are also found
on Oahu: Alectryon macrococcus, Euphorbia haeleeleana, Flueggea
neowawraea, Gouania meyenii, Isodendrion laurifolium, Isodendrion
longifolium, Lobelia niihauensis, Lysimachia filifolia, Mariscus
pennatiformis, Melicope pallida, Peucedanum sandwicense, Phlegmariurus
nutans, Plantago princeps, Platanthera holochila, Schiedea nuttallii,
and Solanum sandwicense. In the final rule designating critical habitat
for plants on Molokai, published on March 19, 2003 (68 FR 12982), we
indicated why that critical habitat was prudent for the following four
multi-island species that are also found on Oahu: Eugenia koolauensis,
Marsilea villosa, Phyllostegia mollis, and Pteris lidgatei. In the
final rule designating critical habitat for plants on Maui and
Kahoolawe, published on May 14, 2003 (68 FR 25934) we indicated why we
believe that critical habitat was prudent for the following eight
multi-island species that are also found on Oahu: Colubrina
oppositifolia, Gouania vitifolia, Hedyotis coriacea, Hesperomannia
arbuscula, Nototrichium humile, Phyllostegia parviflora, Sanicula
purpurea, and Schiedea hookeri.
We examined the potential threats and benefits for the other 54
taxa and have not, at this time, found specific evidence of taking,
vandalism, collection, or trade of these taxa or of similarly situated
species. Consequently, while we remain concerned that these activities
could potentially threaten these 54 plant species in the future,
consistent with applicable regulations (50 CFR 424.12(a)(1)(i)) and the
court's discussion of these regulations, we do not find that any of
these species are currently threatened by taking or other human
activity. None of these threats would be exacerbated by the designation
of critical habitat.
In the absence of finding that critical habitat would increase
threats to a species, if there are any benefits to critical habitat
designation, then a prudent finding is warranted. The potential
benefits of designation of critical habitat for these 54 species
include: (1) Triggering section 7 consultation in new areas where it
would not otherwise occur because, for example, it is or has become
unoccupied or the occupancy is in question; (2) focusing conservation
activities on the most essential areas; (3) providing educational
benefits to State or county governments or private entities; and 4)
preventing people from causing inadvertent harm to the species.
In the case of these 54 species, there would be some benefits to
critical habitat. The primary regulatory effect of critical habitat is
the section 7 requirement that Federal agencies refrain from taking any
action that is likely to destroy or adversely affect critical habitat.
Thirty-seven of these species are reported on or near Federal lands
(see Table 1), where actions are subject to section 7 consultation.
Although a majority of the species considered in this rule are located
exclusively on non-Federal lands with limited Federal activities, there
could be Federal actions affecting these lands in the future. While a
critical habitat designation for habitat currently occupied by these
species would not likely change the section 7 consultation outcome,
since an action that destroys or adversely modifies such critical
habitat would also be likely to result in jeopardy to the species,
there may be instances where section 7 consultation would be triggered
only if critical habitat were designated. There would also be some
educational or informational benefits to the designation of critical
habitat. Benefits of designation would include the notification of land
owners, land managers, and the general public of the importance of
protecting the habitat of these species and dissemination of
information regarding their essential habitat requirements.
Therefore, designation of critical habitat is prudent for these 54
plant species: Abutilon sandwicense, Alsinidendron obovatum,
Alsinidendron trinerve, Chamaesyce celastroides var. kaenana,
Chamaesyce deppeana, Chamaesyce herbstii, Chamaesyce kuwaleana,
Chamaesyce rockii, Cyanea acuminata, Cyanea crispa, Cyanea grimesiana
ssp. obatae, Cyanea humboltiana, Cyanea koolauensis, Cyanea longiflora,
Cyanea pinnatifida, Cyanea st.-johnii, Cyanea superba, Cyanea truncata,
Cyrtandra dentata, Cyrtandra polyantha, Cyrtandra subumbellata,
Cyrtandra viridiflora, Delissea subcordata, Diellia falcata, Diellia
unisora, Dubautia herbstobatae, Eragrostis fosbergii,
[[Page 36012]]
Gardenia mannii, Hedyotis degeneri, Hedyotis parvula, Labordia
cyrtandrae, Lepidium arbuscula, Lipochaeta lobata var. leptophylla,
Lipochaeta tenuifolia, Lobelia gaudichaudii ssp. koolauensis, Lobelia
monostachya, Lobelia oahuensis, Melicope lydgatei, Melicope saint-
johnii, Myrsine juddii, Neraudia angulata, Phyllostegia hirsuta,
Phyllostegia kaalaensis, Sanicula mariversa, Schiedea kaalae, Schiedea
kealiae, Silene perlmanii, Stenogyne kanehoana, Tetramolopium
filiforme, Tetraplasandra gymnocarpa, Trematolobelia singularis, Urera
kaalae, Viola chamissoniana ssp. chamissoniana, and Viola oahuensis
because the potential benefits of critical habitat designation outweigh
the potential threats.

included the known locations; site-specific species information from
the HINHP database and our own rare plant database; species information
from the Center for Plant Conservation's (CPC's) rare plant monitoring
database housed at the University of Hawaii's Lyon Arboretum; island-
wide Geographic Information System (GIS) coverages (e.g., vegetation,
soils, annual rainfall, elevation contours, landownership); the final
listing rules for these 99 species; the May 28, 2002, proposal;
information received during the public comment periods and public
hearings; recent biological surveys and reports; our recovery plans for
these species; discussions with botanical experts; and recommendations
from the Hawaii and Pacific Plant Recovery Coordinating Committee
(HPPRCC) (see also the discussion below) (CPC in litt. 1999; GDSI 2000;
HINHP Database 2000; HPPRCC 1998; Service 1994, 1995a, 1995b, 1996a,
1996b, 1996c, 1996d, 1997, 1998a, 1998b, 1999; 67 FR 37108).
In 1994, the HPPRCC initiated an effort to identify and map habitat
it believed to be important for the recovery of 282 endangered and
threatened Hawaiian plant species. The HPPRCC identified these areas on
most of the islands in the Hawaiian chain, and in 1999, we published
them in our Recovery Plan for the Multi-Island Plants (Service 1999).
The HPPRCC expects there will be subsequent efforts to further refine
the locations of important habitat areas and that new survey
information or research may also lead to additional refinement of
identifying and mapping of habitat important for the recovery of these
species.
The HPPRCC identified essential habitat areas for all listed,
proposed, and candidate plants and evaluated species of concern to
determine if essential habitat areas would provide for their habitat
needs. However, the HPPRCC's mapping of habitat is distinct from the
regulatory designation of critical habitat as defined by the Act. More
data have been collected since the recommendations made by the HPPRCC
in 1998. Much of the area that was identified by the HPPRCC as
inadequately surveyed has now been surveyed to some degree. New
location data for many species have been gathered. Also, the HPPRCC
identified areas as essential based on species clusters (areas that
included listed species as well as candidate species and species of
concern), while we have only delineated areas that are essential for
the conservation of the 99 listed species at issue. As a result, the
critical habitat designations in this rule include not only some
habitat that was identified as essential in the 1998 recommendations
but also habitat that was not identified as essential in those
recommendations.
C. Primary Constituent Elements
In accordance with section 3(5)(A)(i) of the Act and regulations at
50 CFR 424.12, in determining which areas to propose as critical
habitat, we are required to base critical habitat determinations on the
best scientific and commercial data available and to consider those
physical and biological features (primary constituent elements) that
are essential to the conservation of the species. These features
include, but are not limited to: Space for individual and population
growth, and for normal behavior; food, water, air, light, minerals, or
other nutritional or physiological requirements; cover or shelter;
sites for breeding, reproduction, or rearing of offspring, germination,
or seed dispersal; and habitats that are protected from disturbance or
are representative of the historic geographical and ecological
distributions of a species.

Vigna o-wahuensis, Viola chamissoniana ssp. chamissoniana, and Viola
oahuensis is described in the ``Background'' section of this final
rule.
All areas designated as critical habitat are within the historical
range of the 99 species at issue and contain one or more of the
physical or biological features (primary constituent elements)
essential for the conservation of the species.
As described in the discussions for each of the 99 species for
which we are designating critical habitat, we are defining the primary
constituent elements on the basis of the habitat features of the areas
from which the plant species are reported, as described by the type of
plant community (e.g., mesic Metrosideros polymorpha forest),
associated native plant species, locale information (e.g., steep rocky
cliffs, talus slopes, gulches, stream banks), and elevation. The
habitat features provide the ecological components required by the
plant. The type of plant community and associated native plant species
indicate specific microclimate (localized climatic) conditions,
retention and availability of water in the soil, soil microorganism
community, and nutrient cycling and availability. The locale indicates
information on soil type, elevation, rainfall regime, and temperature.
Elevation indicates information on daily and seasonal temperature and
sun intensity. Therefore, the descriptions of the physical elements of
the locations of each of these species, including habitat type, plant
communities associated with the species, location, and elevation, as
described in the ``SUPPLEMENTARY INFORMATION: Discussion of the Plant
Taxa'' section above, constitute the primary constituent elements for
these species on the island of Oahu.
D. Criteria Used To Identify Critical Habitat
The lack of detailed scientific data on the life history of these
plant species makes it impossible for us to develop a robust
quantitative model (e.g., population viability analysis (National
Research Council 1995)) to identify the optimal number, size, and
location of critical habitat units to achieve recovery (Beissinger and
Westphal 1998; Burgman et al. 2001; Ginzburg et al. 1990; Karieva and
Wennergren 1995; Menges 1990; Murphy et al. 1990; Taylor 1995).
However, based on the best information available at this time,
including information on which the listing of and recovery plans for
these species were based, we have concluded that the current size and
distribution of the extant populations are not sufficient to expect a
reasonable probability of long-term survival and recovery of these
plant species.
For each of these species, the overall recovery strategy outlined
in the approved recovery plans includes: (1) Stabilization of existing
wild populations, (2) protection and management of habitat, (3)
enhancement of existing small populations and reestablishment of new
populations within historic range, and (4) research on species biology
and ecology (Service 1994, 1995a, 1995b, 1996a, 1996b, 1996c, 1996d,
1997, 1998a, 1998b, 1999). Thus, the long-term recovery of these
species is dependent upon the protection of existing population sites
and suitable unoccupied habitat within their historic range.
The overall recovery goal stated in the recovery plans for each of
these species includes the establishment of 8 to 10 populations with a
minimum of 100 mature, reproducing individuals per population for long-
lived perennials; 300 mature, reproducing individuals per population
for short-lived perennials; and 500 mature, reproducing individuals per
population for the annual. (Please note that there are some specific
exceptions to this general recovery goal of 8 to 10 populations for
species that are believed to be very narrowly distributed.) To be
considered recovered, the populations of a multi-island species should
be distributed among the islands of its known historic range (Service
1994, 1995a, 1995b, 1996a, 1996b, 1996c, 1996d, 1997, 1998a, 1998b,
1999). A population, for the purposes of this discussion and as defined
in the recovery plans for these species, is a unit in which the
individuals could be regularly cross-pollinated and influenced by the
same small-scale events (such as landslides), and which contains a
minimum of 100, 300, or 500 mature, reproducing individuals, depending
on whether the species is a long-lived perennial, short-lived
perennial, or annual.
Marsilea villosa, a short-lived perennial aquatic fern, was
historically known from six populations on three different islands,
Molokai, Oahu, and Niihau. This species is now extant only on Oahu and
Molokai. Delisting objectives for this species include protection and
stabilization of at least six (rather than 8 to 10) geographically
distinct, self-sustaining populations (either three on Oahu and three
on Molokai or three on Oahu, two on Molokai, and one on Niihau), stable
or increasing population sizes, no active management needed, and self-
maintenance of each population through two successive floods resulting
in sexual reproduction. Delisting objectives for Marsilea villosa do
not include a specific number of mature individuals per population
because of its clonal nature, as it is extremely difficult to
distinguish between individuals in clonal plant species (Service
1996a).
By adopting the specific recovery objectives enumerated above, the
adverse effects of genetic inbreeding and random environmental events
and catastrophes, such as landslides, hurricanes or tsunamis, which
could destroy a large percentage of a species at any one time, may be
reduced (Menges 1990; Podolsky 2001). These recovery objectives were
initially developed by the HPPRCC and are found in all of the recovery
plans for these species. While they are expected to be further refined
as more information on the population biology of each species becomes
available, the justification for these objectives is found in the
current conservation biology
[[Page 36014]]
literature addressing the conservation of rare and endangered plants
and animals (Beissinger and Westphal 1998; Burgman et al. 2001; Falk et
al.1996; Ginzburg et al. 1990; Hendrix and Kyhl 2000; Karieva and
Wennergren 1995; Luijten et al. 2000; Meffe and Carroll 1996; Menges
1990; Murphy et al.1990; Podolsky 2001; Quintana-Ascencio and Menges
1996; Taylor 1995; Tear et al. 1995; Wolf and Harrison 2001). The
overall goal of recovery in the short-term is a successful population
that can carry on basic life history processes, such as establishment,
reproduction, and dispersal, at a level where the probability of
extinction is low. In the long-term, the species and its populations
should be at a reduced risk of extinction and be adaptable to
environmental change through evolution and migration.
Many aspects of a species' life history are typically considered to
determine guidelines for its interim stability and recovery, including
longevity, breeding system, growth form, fecundity, ramet (a plant that
is an independent member of a clone) production, survivorship, seed
longevity, environmental variation, and successional stage of the
habitat. Hawaiian species are poorly studied, and the only one of these
characteristics that can be uniformly applied to all Hawaiian plant
species is longevity (i.e., long-lived perennial, short-lived
perennial, and annual). In general, long-lived woody perennial species
would be expected to be viable at population levels of 50 to 250
individuals per population, while short-lived perennial species would
be viable at population levels of 1,500 to 2,500 individuals or more
per population. These population numbers were refined for Hawaiian
plant species by the HPPRCC (1994) due to the restricted distribution
of suitable habitat typical of Hawaiian plants and the likelihood of
smaller genetic diversity of several species that evolved from a single
introduction. For recovery of Hawaiian plants, the HPPRCC recommended a
general recovery guideline of 100 mature, reproducing individuals per
population for long-lived perennial species; 300 mature, reproducing
individuals per population for short-lived perennial species; and 500
mature, reproducing individuals per population for annual species.
The HPPRCC also recommended the conservation and establishment of 8
to 10 populations to address the numerous risks to the long-term
survival and conservation of Hawaiian plant species. Although absent
the detailed information inherent to the types of population viability
analysis models described above (Burgman et al. 2001), this approach
employs two widely recognized and scientifically accepted goals for
promoting viable populations of listed species--(1) creation or
maintenance of multiple populations so that a single or series of
catastrophic events cannot destroy the entire listed species (Luijten
et al. 2000; Menges 1990; Quintana-Ascencio and Menges 1996); and (2)
increasing the size of each population in the respective critical
habitat units to a level where the threats of genetic, demographic, and
normal environmental uncertainties are diminished (Hendrix and Kyhl
2000; Luijten et al. 2000; Meffe and Carroll 1996; Podolsky 2001;
Service 1997; Tear et al. 1995; Wolf and Harrison 2001). In general,
the larger the number of populations and the larger the size of each
population, the lower the probability of extinction (Meffe and Carroll
1996; Raup 1991). This basic conservation principle of redundancy
applies to Hawaiian plant species. By maintaining 8 to 10 viable
populations in several critical habitat units, the threats represented
by a fluctuating environment are alleviated and the species has a
greater likelihood of achieving long-term survival and recovery.
Conversely, loss of one or more of the plant populations within any
critical habitat unit could result in an increase in the risk that the
entire listed species may not survive and recover.
Due to the reduced size of suitable habitat areas for these
Hawaiian plant species, they are now more susceptible to the variations
and weather fluctuations affecting quality and quantity of available
habitat, as well as direct pressure from hundreds of species of
nonnative plants and animals. Establishing and conserving 8 to 10
viable populations on one or more islands within the historic range of
the species will provide each species with a reasonable expectation of
persistence and eventual recovery, even with the high potential that
one or more of these populations will be eliminated by normal or random
adverse events, such as the hurricanes that occurred in 1982 and 1992
on Kauai, fires, and nonnative plant invasions (HPPRCC 1998; Luijten et
al. 2000; Mangel and Tier 1994; Pimm et al. 1998; Stacey and Taper
1992). We conclude that designation of adequate suitable habitat for 8
to 10 populations as critical habitat is essential to give the species
a reasonable likelihood of long-term survival and conservation, based
on currently available information.
In summary, the long-term survival and conservation of Hawaiian
plant species requires the designation of critical habitat units on one
or more of the Hawaiian islands with suitable habitat for 8 to 10
populations of each plant species. Some of this habitat is currently
not known to be occupied by these species. To recover the species, it
is essential to conserve suitable habitat in these unoccupied units,
which in turn will allow for the establishment of additional
populations through natural recruitment or managed reintroductions.
Establishment of these additional populations will increase the
likelihood that the species will survive and recover in the face of
normal and stochastic events (e.g., hurricanes, fire, and nonnative
species introductions) (Mangel and Tier 1994; Pimm et al. 1998; Stacey
and Taper 1992).
In this rule, we have defined the primary constituent elements
based on the general habitat features of the areas from which the
plants are reported, such as the type of plant community, the
associated native plant species, the physical location (e.g., steep
rocky cliffs, talus slopes, stream banks), and elevation. The areas we
are designating as critical habitat provide some or all of the habitat
components essential for the conservation of the 99 plant species as
discussed in the individual unit descriptions.
Our approach to delineating critical habitat units was applied in
the following manner:
1. Critical habitat was proposed and has been designated on an
island by island basis for ease of understanding for landowners and the
public, for ease of conducting the public hearing process, and for ease
of conducting public outreach. In Hawaii, landowners and the public are
most interested and affected by issues centered on the island on which
they reside.
2. We focused on designating units representative of the known
current and historical geographic and elevational range of each
species; and
3. We designed critical habitat units to allow for expansion of
existing wild populations and reestablishment of wild populations
within the historic range, as recommended by the recovery plans for
each species.
The proposed critical habitat units were delineated by creating
rough units for each species by screen digitizing polygons (map units)
using ArcView (Environmental Systems Research Institute, Inc.), a
computer GIS program. We created polygons by overlaying current and
historic plant location points onto digital topographic maps of each of
the islands.
We then evaluated the resulting shape files (delineating historic
elevational range and potentially suitable habitat). We refined
elevation ranges, and we
[[Page 36015]]
avoided areas identified as not suitable for a particular species
(i.e., not containing the primary constituent elements). We then
considered the resulting shape files for each species to define all
suitable habitat on the island, including occupied and unoccupied
habitat.
We further evaluated these shape files of suitable habitat. We used
several factors to delineate the proposed critical habitat units from
these land areas. We reviewed the recovery objectives, as described
above and in recovery plans for each of the species, to determine if
the number of populations and population size requirements needed for
conservation would be available within the suitable habitat units
identified as containing the appropriate primary constituent elements
for each species. If more than the area needed for the number of
recovery populations was identified as potentially suitable, only those
areas within the least disturbed suitable habitat were included as
proposed critical habitat. A population for this purpose is defined as
a discrete aggregation of individuals located a sufficient distance
from a neighboring aggregation such that the two are not affected by
the same small-scale events and are not believed to be consistently
cross-pollinated. In the absence of more specific information
indicating the appropriate distance to assure limited cross-
pollination, we are using a distance of 1,000 m (3,280 ft) based on our
review of current literature on gene flow (Barret and Kohn 1991;
Fenster and Dudash 1994; Havens 1998; Schierup and Christiansen 1996).
We further refined the resulting critical habitat units by using
satellite imagery and parcel data to eliminate areas that did not
contain the appropriate vegetation or associated native plant species,
as well as features such as cultivated agriculture fields, housing
developments, and other areas that are unlikely to contribute to the
conservation of one or more of the 99 plant species for which critical
habitat was proposed on May 28, 2002. We used geographic features
(ridge lines, valleys, streams, coastlines, etc.) or manmade features
(roads or obvious land use) that created an obvious boundary for a unit
as unit area boundaries.
Following publication of the proposed critical habitat rules, some
of which were revised, for 255 Hawaiian plants (67 FR 3940, 67 FR 9806,
67 FR 15856, 67 FR 16492, 67 FR 34522, 67 FR 36968, 67 FR 37108), we
reevaluated proposed critical habitat. State-wide, for each species
using the applicable recovery guidelines (generally 8 to 10 populations
with a minimum of 100 mature, reproducing individuals per population
for long-lived perennial species; 300 mature, reproducing individuals
per population for short-lived perennial species; and 500 mature,
reproducing individuals per population for annual species) to determine
if we had inadvertently proposed for designation too much or too little
habitat to meet the essential recovery goals (HINHP Database 2000,
2001; Wagner et al. 1990, 1999).
Based on comments and information we received during the comment
periods, we assessed the proposed critical habitat in order to
ascertain which areas contained the highest quality habitat, had the
highest likelihood of species conservation, were geographically
distributed within the species' historical range, and were located a
sufficient distance from each other such that populations of a single
species are unlikely to be impacted by a single catastrophic event. We
ranked areas of the proposed critical habitat by the quality of the
primary constituent elements (e.g., intact native plant communities,
predominance of associated native plants versus nonnative plants),
potential as a conservation area (e.g., whether the land is zoned for
conservation or whether the landowner is already participating in plant
conservation actions), and current or expected management of known
threats (e.g., ungulate control; weed control; nonnative insect, slug,
and snail control). Of these most essential areas, we selected adequate
area to provide for 8 to 10 populations distributed among the islands
of each species' historical range.
Areas that contain high quality primary constituent elements and
conservation potential (e.g., are zoned for conservation and have
ongoing or expected threat abatement actions) were ranked the most
essential. This ranking process also included determining which
habitats were representative of the historic geographical and
ecological distributions of the species (see ``Primary Constituent
Elements''). Of the proposed critical habitat for a species, areas that
were not ranked most essential and that may provide habitat for
populations above the recovery goal of 8 to 10 populations were
determined not essential for the conservation of the species and were
excluded from the final designation. Areas that were excluded because
the benefits of exclusion outweigh the benefits of inclusion under
4(b)(2) of the Act are included in the total count of habitat for 8 to
10 populations.
In selecting areas of designated critical habitat, we made an
effort to avoid developed areas, such as towns and other similar lands,
that are unlikely to contribute to the conservation of the 99 species.
However, the minimum mapping unit that we used to approximate our
delineation of critical habitat for these species did not allow us to
exclude all such developed areas from the maps. Existing manmade
features and structures within the boundaries of the mapped areas, such
as buildings; roads; aqueducts and other water system features,
including, but not limited to pumping stations, irrigation ditches,
pipelines, siphons, tunnels, water tanks, gaging stations, intakes,
reservoirs, diversions, flumes, and wells; existing trails; campgrounds
and their immediate surrounding landscaped area; scenic overlooks;
remote helicopter landing sites; existing fences; telecommunications
towers and associated structures and equipment; electrical power
transmission lines and distribution, and communication facilities and
regularly maintained associated rights-of-way and access ways; radars;
telemetry antennas; missile launch sites; arboreta and gardens; heiau
(indigenous places of worship or shrines) and other archaeological
sites; airports; other paved areas; lawns and other rural residential
landscaped areas do not contain one or more of the primary constituent
elements and are therefore excluded from critical habitat designation
under the terms of this regulation. Federal actions limited to those
areas would not trigger a section 7 consultation unless they affect the
species or primary constituent elements in adjacent critical habitat.
In summary, for these species, we utilized the approved recovery
plan guidance to identify appropriately sized land units containing
essential occupied and unoccupied habitat. Based on the best available
information, we believe these areas constitute the essential habitat on
Oahu to provide for the recovery of these 99 species.
The critical habitat areas described below constitute our best
assessment of the physical and biological features needed for the
conservation and special management needs of the 99 plant species, and
are based on the best scientific and commercial information available
(as described above). We publish this final rule acknowledging that we
have incomplete information regarding many of the primary biological
and physical requirements for these species. However, both the Act and
the relevant court orders require us
[[Page 36016]]
to proceed with designation at this time based on the best information
available. As new information accrues, we may consider reevaluating the
boundaries of areas that warrant critical habitat designation.

Oahu 20--Adenophorus periens--a
This unit is critical habitat for Adenophorus periens and is 711 ha
(1,759 ac) on State (Kaipapau Forest Reserve, Hauula Forest Reserve,
Sacred Falls State Park , and Kahana Valley State Park) and private
land. This unit contains portions of the Summit Trail and Puu Pauao
Summit. This unit provides habitat for one population of 300 mature,
reproducing individuals of the short-lived perennial Adenophorus
periens and is currently unoccupied. This unit is essential to the
conservation of the species because it supports habitat that is
essential to the establishment of additional populations on Oahu in
order to reach recovery goals. The habitat features contained in this
unit that are essential for this species include, but are not limited
to, tree trunks in Metrosideros polymorpha or Metrosideros rugosa wet
forests. This unit is geographically separated from critical habitat
