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

sp. changed to Melanthera sp. for Sesbania tomentosa; Lipochaeta 
integrifolia changed to Melanthera integrifolia for Peucedanum 
sandwicense; Lipochaeta remyi changed to Melanthera remyi in the 
discussions of Hibiscus brackenridgei and Schiedea kealiae; Lipochaeta 
tenuis changed to Melanthera tenuis in the discussions of Lipochaeta 
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 
holochila; Morinda sandwicensis changed to Morinda trimera for Flueggea 
neowawraea; Myrica faya changed to Morella faya in the discussions of 
Cyanea grimesiana ssp. obatae, Hedyotis parvula, Melicope saint-johnii, 
Schiedea kaalae, Silene perlmanii, Urera kaalae, and Viola 
chamissoniana ssp. chamissoniana; Phymatosorus scolopendria changed to 
Phymatosorus grossus for Diellia erecta; Pluchea symphytifolia changed 
to Pluchea carolinensis for Chamaesyce celastroides var. kaenana; 
Setaria gracilis changed to Setaria parviflora for Labordia cyrtandrae; 
Styphelia tameiameiae changed to Leptecophylla tameiameiae in the 
discussions of Bonamia menziesii, Cenchrus agriminiodes, Eugenia 
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 
sandwicense changed from 16 populations to 30 occurrences; Alectryon 
macrococcus changed from 34 populations to 82 occurrences; 
Alsinidendron obovatum changed from 5 populations to 6 occurrences; 
Alsinidendron trinerve changed from 3 populations to 13 occurrences; 
Bonamia menziesii changed from 16 populations to 18 occurrences;

populations to 23 occurrences; Delissea subcordata changed from 18 
populations to 21 occurrences; Diellia falcata changed from 29 
populations to 30 occurrences; Dubautia herbstobatae changed from 4 
populations to 12 occurrences; Eugenia koolauensis changed from 10

populations to 7 occurrences; Hesperomannia arborescens changed from 23 
populations to 36 occurrences; Isodendrion longifolium changed from 4 
populations to 7 occurrences; Lepidium arbuscula changed from 10 
populations to 12 occurrences; Lipochaeta lobata var. leptophylla

niihauensis changed from 21 populations to 40 occurrences; Lobelia 
oahuensis changed from 10 populations to 12 occurrences; Marsilea 
villosa changed from 4 populations to 5 occurrences; Melicope lydgatei 
changed from 4 populations to 18 occurrences; Melicope saint-johnii 
changed from 5 populations to 6 occurrences; Neraudia angulata changed 
from 5 populations to 27 occurrences; Nototrichium humile changed from 
21 populations to 25 occurrences; Phlegmariurus nutans changed from 5 
populations to 3 occurrences; Phyllostegia hirsuta changed from 23 
populations to 26 occurrences; Phyllostegia kaalaensis changed from 4 
populations to 7 occurrences; Phyllostegia mollis changed from 8 
populations to 5 occurrences; Phyllostegia parviflora changed from 2

from 11 populations to 12 occurrences; Viola chamissoniana ssp. 
chamissoniana changed from 5 populations to 15 occurrences; and Viola 
oahuensis changed from 9 populations to 18 occurrences.
    (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).

Eugenia koolauensis, Euphorbia haeleeleana, Flueggea neowawraea, 
Gardenia mannii, Gouania meyenii, Gouania vitifolia, Hedyotis degeneri, 
Hedyotis parvula, Hesperomannia arborescens, Hesperomannia arbuscula,

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 
ac) to 3,921 ha (9,689 ac). This unit was renamed Oahu 4--Abutilon

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

Oahu J

    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. 
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 14--Marsilea villosa--b.

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 
cyrtandrae, Lobelia gaudichaudii ssp. koolauensis, Melicope lydgatei, 
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.

Oahu R

    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 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 
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 multi-island species, Vigna o-
wahuensis, provides habitat within its historical range for one 
population. No modifications were made to the acreage of this unit, 
which renamed Oahu 24--Vigna o-wahuensis--b.

Oahu T

    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 
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 multi-island species, Vigna o-
wahuensis, provides habitat within its historical range for one 
population. No modifications were made to the acreage of this unit, 
which was renamed Oahu 25--Vigna o-wahuensis--c.

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 
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 
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,

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.

pennatiformis, Marsilea villosa, Melicope lydgatei, Melicope pallida, 
Melicope saint-johnii, Myrsine juddii, Neraudia angulata, Nototrichium 
humile, Peucedanum sandwicense, Phlegmariurus nutans, Phyllostegia 
hirsuta, Phyllostegia kaalaensis, Phyllostegia mollis, Phyllostegia 
parviflora, Plantago princeps, Platanthera holochila, Pteris lidgatei,

Tetramolopium lepidotum ssp. lepidotum, Tetraplasandra gymnocarpa, 
Trematolobelia singularis, Urera kaalae, Vigna o-wahuensis, Viola 
chamissoniana ssp. chamissoniana, and Viola oahuensis. This information 
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.

requirements of Abutilon sandwicense, Adenophorus periens, Alectryon

Tetraplasandra gymnocarpa, Trematolobelia singularis, Urera kaalae, 
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.
