 AGENCY: Fish and Wildlife Service, Interior.
 ACTION: Proposed rule and notice of determinations of whether designation of critical habitat is prudent.
 SUMMARY: We, the U.S. Fish and Wildlife Service (Service), have reconsidered our findings concerning whether designating critical habitat for 20 federally protected plants from the island of Molokai, some of which may also occur on other Hawaiian Islands, would be prudent. The 20 plants were listed as endangered or threatened species under the Endangered Species Act of 1973, as amended (Act), between 1991 and 1999. At the time each plant was listed, we determined that designation of critical habitat was not prudent because designation would increase the degree of threat to the species and/or would not benefit the plant. We determine that critical habitat is prudent for 19 of these species 
                            *(Bidens wiebkei, Brighamia rockii, Canavalia molokaiensis, Clermontia oblongifolia*
                             ssp. 
                            *brevipes, Cyanea dunbarii, Cyanea mannii, Cyanea procera, Hibiscus arnottianus*
                             ssp. 
                            *immaculatus, Lysimachia maxima, Mariscus fauriei, Marsilea villosa, Melicope reflexa, Phyllostegia mannii, Schiedea lydgatei, Schiedea sarmentosa, Silene alexandri, Silene lanceolata, Stenogyne bifida*, and 
                            *Tetramolopium rockii)*
                             because the potential benefits of designating critical habitat essential for the conservation of these species outweigh the risks that may result from human activity because of critical habitat designation. We propose that critical habitat designation is not prudent for one species, 
                            *Pritchardia munroi*, because it would likely increase the threat from vandalism or collection of this species on Molokai. This proposed rule also proposes designation of critical habitat for 17 of these 20 species. Critical habitat is not proposed for two species, 
                            *Lysimachia maxima*
                             and 
                            *Phyllostegia mannii*, that are currently found only in areas on Molokai that do not require special management consideration or protection because they are already protected and managed to the benefit of these species. Thus, these areas do not meet the definition of critical habitat. For one additional species from Molokai, 
                            *Labordia triflora*, we determined that designation of critical habitat was prudent at the time of its listing as an endangered species in 1999. Critical habitat designation for this species is proposed at this time. In other proposed rules we determined that critical habitat was prudent for 19 species that occur on Molokai as well as on Kauai, Niihau, Maui, Kahoolawe, and/or Lanai. The determinations were included in proposed rules for Kauai and Niihau, published on November 7, 2000, for Maui and Kahoolawe, published on December 18, 2000, or for Lanai, published on December 27, 2000. These species are: 
                            *Adenophorous periens, Alectryon macrococcus, Centarium sebaeoides, Ctenitis squamigera, Cyanea grimesiana*
                             ssp. 
                            *grimesiana, Diellia erecta, Hedyotis mannii, Hesperomannia arborescens, Ischaemum byrone, Melicope mucronulata, Neraudia sericea, Peucedanum sandwicense, Plantago princeps, Platanthera holochila, Schiedea nuttallii, Sesbania tomentosa, Spermolepis hawaiiensis, Vigna o-wahuensis*, and 
                            *Zanthoxylum hawaiiense*. Critical habitat designations for 14 of the 19 species on Molokai are proposed at this time. Critical habitat is not proposed for five of these species 
                            *(Adenophorus periens, Hedyotis mannii, Plantago princeps, Plantanthera holochila*, and 
                            *Schiedea nuttallii)*
                             that currently are found in areas on Molokai that do not require special management or protection because they are already protected and managed to the benefit of these species. Thus, these areas do not meet the definition of critical habitat. Critical habitat designations for 32 species within 28 critical habitat units on the Hawaiian island of Molokai are proposed at this time. We solicit data and comments from the public on all aspects of this proposal, including data on the economic and other impacts of the proposed designations. We may revise this proposal to incorporate or address new information received during the comment period.
 DATES: We must receive comments from all interested parties by February 27, 2001. Public hearing requests must be received by February 12, 2001.

SUPPLEMENTARY INFORMATION: Background We, the U.S. Fish and Wildlife Service (Service), have reconsidered our findings concerning whether designating critical habitat for 20 federally protected plants from the island of Molokai is prudent. Currently, 15 of these species 
                        *(Bidens wiebkei, Canavalia molokaiensis, Clermontia oblongifolia*
                         ssp. 
                        *brevipes, Cyanea dunbarii, Cyanea mannii, Cyanea procera, Hibiscus arnottianus*
                         ssp. 
                        *immaculatus, Lysimachia maxima, Melicope reflexa, Pritchardia munroi, Schiedea lydgatei, Schiedea sarmentosa, Silene alexandri, Stenogyne bifida*, and 
                        *Tetramolopium rockii)*
                         are endemic to the island of Molokai while three species 
                        *(Mariscus fauriei, Marsilea villosa*, and 
                        *Silene lanceolata)*
                         are known from Molokai as well as one or more other islands. One species, 
                        *Brighamia rockii*, was known from Lanai, Maui, and Molokai but currently is extant only on Molokai. Another species, 
                        *Phyllostegia mannii*, was 
                        ( print page 83159)
                        known from Maui and Molokai but currently is extant only on Molokai (Table 1). Prudency determinations for 19 other species 
                        *(Adenophorous periens, Alectryon macrococcus, Centarium sebaeoides, Ctenitis squamigera, Cyanea grimesiana*
                         ssp. 
                        *grimesiana, Diellia erecta, Hedyotis mannii, Hesperomannia arborescens, Ischaemum byrone, Melicope mucronulata, Neraudia sericea, Peucedanum sandwicense, Plantago princeps, Platanthera holochila, Schiedea nuttallii, Sesbania tomentosa, Spermolepis hawaiiensis, Vigna o-wahuensis*, and 
                        *Zanthoxylum hawaiiense)*
                         which also occur on the islands of Kauai, Maui and/or Lanai were published in proposed rules on November 7, 2000 (Kauai and Niihau, 65 FR 66808), on December 18, 2000 (Maui and Kahoolawe, 65 FR 79192), or on December 27, 2000 (Lanai). Critical habitat designations for 14 of these 19 species on Molokai are proposed at this time. Critical habitat is not proposed for five species 
                        *(Adenophorous periens, Hedyotis mannii, Plantago princeps, Platanthera holochila*, and 
                        *Schiedea nuttallii)*
                         that currently are found only in areas on Molokai that are protected and managed for the benefit of these species. In addition, for one species in this proposed rule, 
                        *Labordia triflora*, we determined that designation of critical habitat was prudent at the time of its listing as an endangered species in 1999. Critical habitat designation for this species on Molokai is proposed at this time. Table 1.—Summary of Island Distribution of 49 Species on Molokai

 An additional nine species are known on Molokai only from historical records (pre-1970) or from undocumented observations. Prudency determinations and proposed critical habitat designations or non-designations for these species which still occur on other islands are/will be included in the proposed rules for the islands on which they currently occur (Table 2). The 40 plants at issue in this proposed rule were listed as endangered or threatened species under the Endangered Species Act of 1973, as amended (Act), between 1991 and 1999. At the time 39 of these plants were listed, we determined that designation of critical habitat was not prudent because designation would increase the degree of threat to the species and/or would not benefit the plant. These are not prudent determinations, along with 206 others, were challenged in

Supp. 2d 1280). On August 10, 1998, the court ordered us to publish proposed critical habitat designations or non-designations for at least 100 species by November 30, 2000, and to publish proposed designations or non-designations for the remaining 145 species by April 30, 2002 (24 F.

This prudency determination and proposed rule designating critical habitat for 32 plants from the island of Molokai respond to these court orders. We propose that critical habitat is prudent for 19 species (
                        *Bidens wiebkei, Brighamia rockii, Canavalia molokaiensis, Clermontia oblongifolia*
                        ssp. 
                        *brevipes, Cyanea dunbarii, Cyanea mannii, Cyanea procera, Hibiscus arnottianus ssp. immaculatus, Lysimachia maxima, Mariscus fauriei, Marsilea villosa, Melicope reflexa, Phyllostegia mannii, Schiedea lydgatei, Schiedea sarmentosa, Silene alexandri, Silene lanceolata, Stenogyne bifida, Tetramolopium rockii*) because the potential benefits of designating critical habitat essential for the conservation of these species outweigh the risks of designation as a result of human activity. We propose that critical habitat designation is not prudent for one species, 
                        *Pritchardia munroi*, because it would likely increase the threat from vandalism or collection of this species on Molokai. Critical habitat is proposed for designation within 28 critical habitat units on the island of Molokai. The land area within these units totals 6,165 hectares (ha) (15,230 acres (ac)). If this proposal is made final, section 7 of the Act would prohibit destruction or adverse modification of critical habitat through any activity funded, authorized, or carried out by any Federal agency. Section 4 of the Act requires us to consider economic and other impacts of specifying any particular area as critical habitat. The Island of Molokai The island of Molokai, the fifth largest in the Hawaiian Islands chain, is approximately 61 kilometers (km) (38 miles (mi)) long, up to 17 km (10 mi) wide, and encompasses an area of about 688 sq km (266 sq mi) (57 FR 46325). Three shield volcanoes make up most of the land mass of Molokai: West Molokai Mountain, East Molokai Mountain, and a volcano that formed Kalaupapa Peninsula (57 FR 46325). The taller and larger East Molokai Mountain rises 1,813 meters (m) (4,970 feet (ft)) above sea level and comprises roughly 50 percent of the island's area (57 FR 46325). Topographically, the windward side of East Molokai differs from the leeward side. Precipitous cliffs line the northern windward coast and deep inaccessible valleys dissect the coastal area. The annual rainfall on the windward side is 200 to over 375 centimeters (cm) (75 to over 150 inches (in)), distributed throughout the year. The soils are poorly drained and high in organic matter. The gulches and valleys are usually very steep, but sometimes gently sloping (57 FR 46325). Much of the native vegetation on the northern 
                        ( print page 83161)
                        part of East Molokai is intact because of its relative inaccessibility to humans and animals, although destructive ungulates have begun to enter the coastline in recent years (57 FR 46325). Discussion of the Plant Taxa Species Endemic to Molokai Bidens wiebkei 
                        (ko oko olau) *Bidens wiebkei*, a member of the aster family (Asteraceae), is a short-lived perennial herb which is somewhat woody at the base and grows from 0.5 to 1 m (1.6 to 3.3 ft) tall with opposite, pinnately compound leaves. This plant is distinguished from other 
                        *Bidens*
                         species which grow on Molokai by its erect habit and the curved or twisted, winged achenes (57 FR 46325; Ganders and Nagata 1999). This species was observed in flower during May (Hawaii Natural Heritage Program (HINHP) database 2000). No additional life history information is currently available (United States Fish and Wildlife Service (USFWS) 1996a). Historically 
                        *Bidens wiebkei*
                         was known from Pelekunu and the easternmost section of Molokai at Halawa (HINHP Database 2000). It is found currently in Halawaiki Gulch, Lamaloa Gulch, and below Puu Kolekole on State and privately owned lands (Geographic Decision Systems International (GDSI) 2000; HINHP Database 2000). There are a total of three populations containing more than 200 individuals (HINHP Database 2000). The currently known populations of 
                        *Bidens wiebkei*
                         are scattered along steep, exposed slopes in

                         (pukiawe) lowland shrubland between 250 and 1,050 m (820 to 3,450 ft) in elevation, extending over a distance of 4 by 1.6 km (2.5 by 1 mi) (Gagne and Cuddihy 1999; HINHP Database 2000; Ganders and Nagata 1999). Other associated plant species include 
                        *Antidesma*
                         sp. (hame),

                         (naupaka kuahiwi) (HINHP Database 2000). The major threats to 
                        *Bidens wiebkei*
                         on Molokai, include habitat degradation and possible predation by deer (
                        *Axis axis*) and feral goats (
                        *Capra hircus*); competition with non-native plants, such as 
                        *Melinus minutiflora*
                         (molasses grass) and 
                        *Schinus terebinthifolius*
                         (Christmas berry); fire; and damage by humans of those plants found along trails (HINHP Database 2000; 57 FR 46325). Canavalia molokaiensis (awikiwiki) *Canavalia molokaiensis*, a member of the legume family (Fabaceae), is a short-lived perennial climbing herb with twining branches with leaves made up of three lance-shaped or sometimes oval leaflets. The only species of this genus found on Molokai, this plant can be distinguished from others in the genus by its narrower leaflets and its larger, rose-purple flowers (57 FR 46325; Wagner and Herbst 1999). This species has been observed in flower during May and December (HINHP Database 2000). Fruits and flowers were observed in March (HINHP Database 2000). No additional life history information is currently available (USFWS 1996a). Historically, 
                        *Canavalia molokaiensis*
                         was known from East Molokai at Kalaupapa, Pelekunu, and farther south in Kahuaawi Gulch, and the region of Manawai (HINHP Database 2000). It now has a more restricted range, from Kalaupapa to Waialeia, Kaunakakai, Pelekunu, and Kamakou (HINHP Database 2000). There are a total of seven populations containing more than 50 plants on State lands, including lands managed by the National Park Service at Kalaupapa National Historical Park, and privately owned lands (GDSI 2000; HINHP Database 2000). *Canavalia molokaiensis*
                         typically grows in exposed sites, both dry and mesic, on steep slopes in 
                        *Metrosideros polymorpha-Dodonea viscosa*
                         lowland shrubland and mesic shrublands between 10 and 900 m (30 to 3,060 ft) in elevation (HINHP Database 2000). Associated plant species include 
                        *Artemesia*
                         sp. (hinahina), 
                        *Chamaesyce*
                         sp. (akoko), 
                        *Coprosma*
                         sp. (pilo), 
                        *Styphelia tameiameiae*, and Wikstroemia sp. (akia) (HINHP Database 2000). The threats to this species on Molokai include habitat degradation by feral ungulates such as goats and pigs (
                        *Sus scrofa*), possible predation by feral goats, and competition with non-native plants, such as 
                        *Melinis minutiflora*
                         (USFWS 1996a). Clermonita oblongifolia ssp. 
                        *brevipes*
                         (oha wai) *Clermontia oblongifolia*
                         ssp. 
                        *brevipes*, a member of the bellflower family (Campanulaceae), is a short-lived perennial shrub or tree which reaches a height of 2 to 7 m (6.6 to 23 ft). This species is distinguished from others in the genus by the structure of its calyx and corolla as well as by the lengths of the flower, the floral lobes, and the green hypanthium. This subspecies differs from others of the species by the shape and length of its leaves, leaf stalks, and flower stalks (Lammers 1988, 1999). No life history information for this species is currently available (USFWS 1996a). *Clermontia oblongifolia*
                         ssp. 
                        *brevipes*
                         is known from a single population of five individuals on the privately owned land of the Nature Conservancy of Hawaii's (TNCH) Kamakou Preserve (HINHP Database 2000; USFWS 1996a; Joel Lau, HINHP, 
                        *in litt.*
                         2000). The historical range of this subspecies is not known (USFWS 1996a). *Clermontia oblongifolia*
                         ssp. 
                        *brevipes*
                         occurs in shallow soil on gulch slopes in the wet

                        *in litt.*
                         2000). Associated plant species include 
                        *Cheirodendron trigynum*
                         (olapa),

                        *in litt.*
                         2000). The threats to this species on Molokai are habitat degradation by feral pigs; possible predation on the fruit or plant parts by rats (
                        *Rattus rattus*), as evidence on related species suggests (USFWS 1996a; 57 FR 46325); and random naturally occurring events that may cause the extinction of the entire taxon due to its single population and very low number of individuals. Cyanea dunbarii 
                        (haha) *Cyanea dunbarii*, a member of the bellflower family (Campanulaceae), is a short-lived perennial, branched shrub 1.5 to 2 m (4.9 to 6.6 ft) tall with oval to broadly elliptic leaves that have irregularly lobed or cleft margins. This species is distinguished from others in this endemic Hawaiian genus by the lack of prickles on the stems and the irregularly lobed and cleft leaf margins (Lammers 1999). *Cyanea dunbarii*
                         was observed in flower, with immature fruit, in September (HINHP Database 2000). No additional life history information is currently available (USFWS 1998a). *Cyanea dunbarii*
                         was collected in 1918 at Waihanau and Waialae Valleys, and was not observed again until 1992, when Joel Lau of the Hawaii Natural Heritage Program found it in Mokomoko Gulch on State owned land within Molokai Forest Reserve (GDSI 2000; HINHP Database 2000; 61 FR 53130; Ken Wood, National Tropical Botanical Garden (NTBG), 
                        *in litt.*
                         2000). Currently, it is known from a single population of 
                        ( print page 83162)
                        approximately 30 mature plants at an elevation of 671 m (2,200 ft) (HINHP Database 2000; K. Wood, 
                        *in litt.*

                         lowland forest on moderate to steep slopes (HINHP Database 2000). Associated species include 
                        *Diplazium sandwicianum*
                         (hoio),

                         (ieie) (USFWS 1998a). The major threats to this single population of 
                        *Cyanea dunbarii*
                         on Molokai are competition with the non-native plants 
                        *Buddleia asiatica*
                         (butterfly bush), 
                        *Erigeron karvinskianus*

                        *Hedychium gardnerianum*
                         (ginger), and 
                        *Kalanchoe pinnata*
                         (air plant); and catastrophic extinction by naturally occurring events such as landslides or flooding, and/or reduced reproductive vigor due to the small number of individuals in the only known population. In addition, predation by rats is a potential threat since rats are known to be in the area and are known to eat stems and fruits of other species of 
                        *Cyanea*; habitat degradation and predation by axis deer and pigs are other potential threats to this species, because both of these species are known to occur in areas adjacent to the only known population (USFWS 1998a; Cuddihy and Stone 1990). Cyanea 
                        mannii (haha) *Cyanea mannii*, a member of the bellflower family (Campanulaceae), is a branched short-lived perennial shrub 1.5 to 3 m (5 to 10 ft) tall with narrowly elliptic or lance-shaped leaves. This species is distinguished from the seven other species of the genus on Molokai by a combination of the following characters: a branched, woody habit; leaves with small, hardened, marginal teeth; and a purplish corolla (Lammers 1999; 57 FR 46325). *Cyanea mannii*
                         has been observed in flower during July (HINHP Database 2000). No additional life history information is currently available (USFWS 1996a). Historically, 
                        *Cyanea mannii*
                         was known only from Kalae on East Molokai (HINHP Database 2000). In 1984, a single plant was discovered by Joan Aidem on privately owned land west of Puu Kolekole on East Molokai (HINHP Database 2000; Lammers 1999; USFWS 1996a). Since then, eight additional populations have been discovered in the east and west forks of Kawela Gulch on the privately owned land of TNCH's Kamakou Preserve on East Molokai and within the State's Molokai Forest Reserve (K. Wood, 
                        *in litt.*
                         2000; HINHP Database 2000). These nine populations contain approximately 200 individuals on State and privately owned lands (GDSI 2000; HINHP Database 2000; K. Wood, 
                        *in litt.*
                         2000). This species typically grows on the sides of deep gulches in 
                        *Metrosideros polymorpha*
                         dominated montane mesic forest at elevations between 559 and 1,220 m (1,900 to 4,000 ft) (HINHP Database 2000; Lammers 1999; USFWS 1996a). Associated plant species include 
                        *Wiskstroemia*
                         sp., 
                        *Dicranopteris linearis*, and 
                        *Vaccinium*
                         sp. (ohelo) (USFWS 1996a). Threats to 
                        *Cyanea mannii*
                         on Molokai are habitat degradation by feral pigs; predation by rats who may feed on the fruit or other parts of the plant, as suggested by evidence from related species; catastrophic extinction through naturally occurring events that this species is vulnerable to due to its few populations and small number of individuals (USFWS 1996a). Cyanea procera 
                        (haha) *Cyanea procera*, a member of the bellflower family (Campanulaceae), is a palm-like short-lived perennial tree 3 to 9 m (10 to 30 ft) tall with stalkless, lance-shaped leaves 60 to 75 cm (24 to 30 in) long and 10 to 17 cm (3.9 to 6.7 in) wide with tiny hardened teeth along the margins. This species can be distinguished from other species of the genus by its growth habit, its sessile leaves, and the single-lipped appearance of the corolla (Lammers 1999; 57 FR 46325). No life history information is currently available for this species (USFWS 1996a). Historically, 
                        *Cyanea procera*
                         was known only from an unspecified site in the Kamalo region of East Molokai (HINHP Database 2000). Currently, this species is found on the privately owned lands of Kamakou Preserve and the State's Puu Alii Natural Area Reserve (NAR) in a total of five populations containing at least 10 individuals (GDSI 2000; HINHP Database 2000). *Cyanea procera*
                         is found on the walls of steep gulches in wet 
                        *Metrosideros polymorpha*
                         dominated lowland mixed forest between 935 and 1,073 m (3,180 to 3,650 ft) elevation (HINHP Database 2000). Associated plant species include various species of 
                        *Asplenium, Brousaissia arguta, Coprosma ochracea*

The flowers of this species are functionally unisexual (Motley 1995; HINHP Database 2000). No additional life history information is available at this time. Until 1990, 
                        *Labordia triflora*
                         was known only from the type collection at Mapulehu, on the island of Molokai (Motley 1995) and was believed to be extinct. In 1990, Joel Lau rediscovered the species in Kua Gulch on Molokai (HINHP Database 2000; Motley 1995). Currently, only 10 individuals are known from privately owned land (GDSI 2000; HINHP Database 2000). This species occurs in mixed lowland mesic forest, at an elevation of ca. 800 m (2,600 ft).

                         landslides); reduced reproductive vigor due to the small number of individuals in the only known population (USFWS 1998a); habitat degradation and/or predation by feral pigs and goats that are known from adjacent areas (USFWS 1998a). Melicope reflexa
                         (alani) *Melicope reflexa,*
                         a long-lived perennial of the citrus family (Rutaceae), is a sprawling shrub 1 to 3 m (3.3 to 10 ft) tall with short, yellowish-brown, short-lived hairs on new growth. Opposite leaves with leaf stalks usually over 1 cm (0.4 in) long, larger leaves and fruit, and partially fused sections of capsule separate it from other species of the genus (Stone 
                        *et al.*
                         1999). Currently, no life history information is available for this species (USFWS 1996a). Historically,

                         (loulu) *Pritchardia munroi,*
                         a member of the palm family (Arecaceae), is a perennial tree about 4 to 5 m (13 to 16 ft) tall. The leaves and petioles have scattered, mostly deciduous scales and hairs, somewhat larger on the lower leaf ribs. The leaves are deeply divided into segments which have long, drooping tips. Numerous bisexual or functionally male flowers are arranged in clusters on hairy, branching stalks which originate at the leaf bases. The mature fruit is shiny, black, and nearly spherical. This species is distinguished from others of the genus by its relatively smooth leaves; the grayish-brown hair on the inflorescence stalks, which are shorter than the petioles; and the small size of the fruits (Read and Hodel 1999). Currently, no life history information is available for this species (USFWS 1996a). Historically and currently 
                        *Pritchardia munroi*
                         is found in leeward East Molokai, above Kamalo, near Kapuaokoolau Gulch (HINHP Database 2000, Read and Hodel 1999). The only known wild individual is found on privately owned land (HINHP Database 2000). The only known wild individual grows near the base of a small ravine in remnant dry to mesic forest at an elevation of about 610 m (2,000 ft) (Read and Hodel 1999). Associated plant species include

                         (no common name) *Schiedea lydgatei,*
                         a member of the pink family (Caryophyllaceae), is a low, hairless perennial plant with branched stems 10 to 40 cm (4 to 16 in) long which are woody at the base. The opposite, three-veined leaves are elliptic. Bisexual flowers are arranged in loosely spreading clusters. The capsules open when mature to reveal dark reddish-brown seeds. The opposite, thin, three-veined leaves with petioles and the smooth, open flower clusters with relatively larger, green sepals separate this species from other members of this endemic Hawaiian genus (Wagner 
                        *et al.*
                         1999). This species was observed with flowers and fruit in June (HINHP Database 2000). Currently, no additional life history information is available (USFWS 1996a). 
                        ( print page 83164) Historically, 
                        *Schiedea lydgatei*
                         was found in Kalae, Poholua, Makolelau, and Ohia Gulch on East Molokai (HINHP Database 2000). This species is now known from two scattered populations in a more restricted area in Makakupaia, Kawela, and Makolelau. The two populations are distributed over an area of less than 1.6 by 5.6 km (1 by 3.5 mi), totaling fewer than 1,000 individuals on State and privately owned lands (HINHP Database 2000; GDSI 2000). This species is found along ridges in dry to mesic grassland, shrubland, and forest with scattered native trees. It ranges in elevation from about 600 to 650 m (2,000 to 2,100 ft) (HINHP Database 2000; Wagner 
                        *et al.*

                         (Gagne and Cuddihy 1999). The major threats to 
                        *Schiedea lydgatei*
                         are habitat degradation by feral ungulates; and competition with the non-native plant species 
                        *Melinus minutiflora;*
                         and catastrophic extinction due to random environmental events, primarily fire, (57 FR 46325; USFWS 1996a) because in this species' dry, windswept habitat, a single fire potentially could destroy a large part of the populations. Schiedea sarmentosa
                         (no common name) *Schiedea sarmentosa,*
                         a perennial herb of the pink family (Caryophyllaceae), is a many-branched shrub. The opposite leaves are slender, threadlike, and are covered with dense, gladular hairs. There may be as many as 40 to 60 inflorescences on one plant, often with 50 to 100 flowers in each inflorenscence. The flowers are female on some plants and bisexual on others. The green sepals are egg-shaped and somewhat hairy. The staminodes (false stamens) are half as long as the sepals and two-branched at the tip. The fruits are oval capsules. This species differs from others in this endemic Hawaiian genus by its densely bushy habit, leaf width, hairiness, and staminode length (Wagner, 
                        *et al.*
                         1999). The flowers are female on some plants and bisexual on others. The population on Makolelau Gulch has a frequency 31 percent females. Based on analyses of pollen-ovule ratios, pollen size, inforescence structure, and comparison to other

                         has been found in Kawela Gulch, Makolelau, and Onini Gulch (HINHP Database 2000). Currently, only two populations are known to be extant. One population on the boundary of the privately owned land of TNCH's Kamakou Preserve and State owned land in Onini Gulch has approximately 30 individuals (HINHP Database 2000). The other population occurs on privately owned land in Makolelau, and consists of 4 subpopulations totaling approximately 300 to 400 individuals (USFWS 1998a; GDSI 2000). Estimates of the total number of individuals have ranged up to 1,000 (USFWS 1998a). An accurate count is somewhat difficult because this species is interspersed with

                        *Melinis minutiflora*
                         and 
                        *Ricinus communis*
                        (paaila), and fire. The species is also threatened by a risk of extinction from naturally occurring events due to the low number of populations (61 FR 53130; USFWS 1998a). Silene alexandri
                         (no common name) *Silene alexandri*, a member of the pink family (Caryophyllaceae), is an erect, perennial herb, 30 to 60 cm (1 to 2 ft) tall, and woody at the base. The narrow, elliptic leaves are hairless except for a fringe along the margins. Flowers are arranged in open clusters on stalks. The hairless stems, flowering stalks, and sepals and the larger flowers with white petals separate this species from other members of the genus (Wagner, 
                        *et al*. 1999). Currently, no life history information is available for this species. Historically, 
                        *Silene alexandri*
                         was known from Makolelau and Kamalo on East Molokai. Currently, one population comprising fewer than 10 individuals remains in Makolelau on privately owned land (GDSI 2000; HINHP Database 2000). The only known population is found in remnant dry forest and shrubland at an elevation between 610 and 760 m (2,000 and 2,500 ft) (HINHP Database 2000; Wagner, 
                        *et al.*
                         1999). Associated plant species include 
                        *Dodonaea viscosa, Metrosideros polymorpha, Styphelia tameiameiae, Dicranopteris linearis, Chenopodium oahuense,*

                         (Gagne and Cuddihy 1999). Threats to the single population of 
                        *Silene alexandri*
                         include habitat degradation by feral goats, predation by goats and cattle (
                        *Bos taurus*) may possibly occur, and catastrophic extinction through random environmental events, of which the most serious is fire, due to the vulnerability of this single population (57 FR 46325; USFWS 1996a). Stenogyne bifida 
                        (no common name) *Stenogyne bifida*, a nonaromatic member of the mint family (Lamiaceae), is a climbing perennial herb, with smooth or slightly hairy, four-angled stems. The opposite, membranous, toothed leaves are oval or elliptical in shape, and are hairless except for the midribs. Flowers are usually arranged in groups of two to six in each of several whorls at the ends of the stems. The petals are fused into a nearly straight, yellow tube which flares into pale-brown lobes comprising an upper and a lower lip. The fruits are fleshy, black nutlets. The long, narrow calyx teeth and the deep lobe in the upper lip of the yellow corolla separate this species from others of the genus (Weller and Sakai 1999). Currently, no life history information is available for this species. Historically, 
                        *Stenogyne bifida*
                         was known from scattered populations from Waianui in central Molokai to Pukoo Ridge on East Molokai (HINHP Database 2000). This species is now known from only four East Molokai populations totaling fewer than 10 individuals on Manawai-Kahananui Ridge along the boundary between private and State lands; on Kolo Ridge, at Kamoku flats; and on the eastern fork of Kawela Gulch on the privately owned land of TNCH's Pelekunu Preserve (GDSI 2000; HINHP Database 2000). *Stenogyne bifida*
                         typically grows on steep ridges in 
                        *Metrosideros polymorpha*

                         (alaa) at elevations between 450 and 1,200 m (1,450 and 4,000 ft) (HINHP Database 2000; USFWS 1996a). The most pervasive threat to this species is habitat degradation by ungulates (axis deer, goats, and pigs) (57 FR 46325; USFWS 1996a). Tetramolopium rockii
                         (no common name) *Tetramolopium rockii*, a member of the aster family (Asteraceae), is a glandular, hairy, prostrate perennial shrub which forms complexly branching mats. The species has been divided into two varieties in the most recent treatment of this genus in Hawaii. Leaves of variety 
                        *calcisabulorum*
                         have slightly inrolled edges, and are whitish due to the long silky hairs on their surfaces. Variety 
                        *rockii*
                         has smaller, less hairy, flat, yellowish-green leaves. The leaves of both varieties are spatula-shaped with glands and smooth margins. Flower heads, arranged singly at the ends of flowering stalks are composed of approximately 60 to 100 white ray florets surround 30 to 55 functionally male, yellow, funnel-shaped disk florets. Fruits are achenes topped with white bristles. This species differs from others of the genus by its growth habit, its hairy and glandular surfaces, its spatulate leaf shape, and its yellow disk florets (Lowrey 1999). Currently, no life history information is available for this species (USFWS 1996a). Of the two recognized varieties of 
                        *Tetramolopium rockii,*
                        variety 
                        *rockii*
                         was first discovered at Moomomi about 80 years ago and is still extant in that area. 
                        *Tetramolopium rockii*
                        var. 
                        *rockii*
                         is found in three areas, from Kalawao to Kahinaakalani, Keieho Point to Kaplalauoa, and from Moomomi to Kahinaakalani (HINHP Database 2000). Variety 
                        *calcisabulorum*
                         is only reported from Keieho Point to Kaplalauoa intergrading with variety 
                        *rockii*
                         where their ranges overlap (HINHP Database 2000). The total number of individuals of both varieties in the three populations is estimated to be 174,000; they are located on State lands, including land managed by the National Park Service at Kalaupapa National Historical Park, and privately owned lands (HINHP Database 2000; GDSI 2000). *Tetramolopium rockii*
                         is restricted to hardened calcareous sand dunes or ash-covered basalt in the coastal spray zone or coastal dry shrubland and grassland between 10 and 200 m (30 and 650 ft) in elevation (Lowrey 1999). Native plant species associated with this species include 
                        *Canthium odoratum, Diospyros sandwicensis, Metrosideros polymorpha, Osteomeles anthyllidifolia*
                         (ulei), 
                        *Scaevola*
                         sp. (naupaka), 
                        *Fimbristylis cymosa*
                         (mau u aki aki), 
                        *Heliotropium anomalum*
                        (ahinahina), 
                        *Lipochaeta integrifolia*
                         (nehe), 
                        *Sida fallax*, and 
                        *Sporobolus virginicus*
                        (akiaki) (USFWS 1996a; HINHP Database 2000). The major threats to 
                        *Tetramolopium rockii*
                         are habitat degradation by ungulate (axis deer and cattle) activity and human recreation, competition with the non-native plant 
                        *Prosopis pallida*
                         (kiawe), and catastrophic extinction due to fire (57 FR 46325). Multi-Island Species Adenophorus periens
                         (pendant kihi fern) *Adenophorus periens*, a short-lived perennial member of the grammitis family (Grammitidaceae), is a small, pendant, epiphytic (not rooted on the ground) fern. This species differs from other species in this endemic Hawaiian genus by having hairs along the pinna margins, by the pinnae being at right angles to the midrib axis, by the placement of the sori on the pinnae, and the degree of dissection of each pinna (USFWS 1999; Linney 1989). Little is known about the life history of 
                        *Adenophorus periens*, which seems to grow only in dense closed-canopy forest with high humidity. Its breeding system is unknown but outbreeding is very likely to be the predominant mode of reproduction. Spores are dispersed by wind, possibly by water, and perhaps on the feet of birds or insects (Linney 1989). Spores lack a thick resistant coat which may indicate their longevity is brief, probably measured in days at most. Due to the weak differences between seasons, there seems to be no evidence of seasonality in growth or reproduction. Additional information on reproductive cycles, longevity, specific environmental requirements, and limiting factors is not available (USFWS 1999). Historically, 
                        *Adenophorus periens*
                         was known from Kauai, Oahu, Lanai, East Maui, and Hawaii Island (HINHP Database 2000). Currently, it is known from several locations on Kauai, Molokai, and Hawaii (HINHP Database 2000). On Molokai, it is found in a single population containing seven individuals on the privately owned land within TNCH's Kamakou Preserve (GDSI 2000; HINHP Database 2000). This species, an epiphyte usually growing on 
                        *Metrosideros polymorpha*
                         trunks, is found in 
                        *Metrosideros polymorpha-Myrsine lessertiana*
                         (kolea) forest at elevations between 400 and 1,265 m (1,312 and 4,150 ft) (HINHP Database 2000). It is found in habitats of well-developed, closed canopy providing deep shade and high humidity (Linney 1989). Associated native species include 
                        *Broussasia arguta, Cheirodendron trigynum, Coprosma ochracea, Cyanea*

                         (ohia ha) (HINHP Database 2000; USFWS 1999). The threats to this species on Molokai are habitat degradation by feral pigs and goats, and competition with the non-native plant 
                        *Psidium cattleianum*
                         (strawberry guava) (HINHP Database 2000; 59 FR 56333; USFWS 1999). Alectryon macrococcus 
                        (mahoe) *Alectryon macrococcus*, a long-lived perennial member of the soapberry family (Sapindaceae), consists of two varieties, 
                        *macrococcus*
                         and 
                        *auwahiensis*, both trees with reddish-brown branches and net-veined paper- or leather-like leaves with one to five pairs of sometimes asymmetrical egg-shaped leaflets. The underside of the leaf has dense brown hairs, only when young in 
                        *A. macrococcus*
                        var.

                        *auwahiensis*
                         (only found on East Maui). The only member of its genus found in Hawaii, this species is distinguished from other Hawaiian members of its family by being a tree with a hard fruit 2.5 cm (0.9 in) or more in diameter (Kimura and Nagata 1980; Wagner 
                        *et al*. 1999). *Alectryon macrococcus*
                         is a relatively slow-growing tree that grows in xeric to mesic sites and is adapted to periodic drought. Little else is known about the life history of this species. Flowering cycles, pollination vectors, seed dispersal agents, and specific environmental requirements are unknown. Currently, 
                        *Alectryon macrococcus*
                         var. 
                        *macrococcus*
                        is known from Kauai, Oahu, Maui, and Molokai. On Molakai, it is found on the privately owned land of TNCH's Kamakou Preserve, along the Puu Kolekole jeep road, Kaunakakai Gulch, and Kamiloloa Gulch in a total 
                        ( print page 83166)
                        of six populations containing nine individuals on State and privately owned lands (GDSI 2000; HINHP Database 2000). *Alectryon macrococcus*
                         var. 
                        *macrococcus*
                         typically grows on dry or talus slopes or in gulches within dry or mesic lowland forest between elevations of 360 and 1,070 m (1,181 and 3,510 ft) (HINHP Database 2000; Wagner 
                        *et al*. 1999). Associated native plants include

                        *macrococcus*
                         on Molokai include habitat degradation by feral goats and pigs; competition from non-native plant species such as 
                        *Melinus minutiflora, Pennisetum clandestinum*
                         (kikuyu grass),

                        *e.g.,*
                         fire) due to the very small remaining number of individuals and their limited distribution on Molokai (USFWS 1997; 57 FR 20772; HINHP Database 2000). Brighamia rockii
                         (pua ala) *Brighamia rockii*, a long-lived perennial member of the bellflower family (Campanulaceae), grows as an unbranched stem succulent with a thickened stem that tapers from the base. This species is a member of a unique endemic Hawaiian genus with only one other species, found on Kauai, from which it differs by the color of its petals, its longer calyx (fused sepals) lobes, and its shorter flower stalks (Lammers 1999). Observations of 
                        *Brighamia rockii*
                         by Gemmill (1996) have provided the following information: the reproductive system is protandrous, meaning there is a temporal separation between the production of male and female gametes, in this case a separation of several days; only 5 percent of the flowers produce pollen; very few fruits are produced per inflorescence; there are 20 to 60 seeds per capsule; and plants in cultivation have flowers at an age of 9 months (USFWS 1996a). This species was observed in flower during August (HINHP Database 2000). Historically, 
                        *Brighamia rockii*
                         ranged along the northern coast of East Molokai from Kalaupapa to Halawa and may possibly have grown on Lanai and Maui (HINHP Database 2000; Lammers 1999). Currently, it is only extant on Molokai in a total of five populations with between 121 to 131 individual plants occurring on State and privately owned lands (HINHP Database 2000; GDSI 2000). It occurs on steep, inaccessible sea cliffs along East Molokai's northern coastline from Anapuhi Beach to Wailau Valley on private lands, and on the relatively inaccessible State-owned sea stack of Huelo, east of Anapuhi Beach (HINHP Database 2000; K. Wood,

                         (awiwi) *Centaurium sebaeoides*, a member of the gentian family (Gentianaceae), is an annual herb with fleshy leaves and stalkless flowers. This species is distinguished from 
                        *Centaurium erythraea*, which is naturalized in Hawaii, by its fleshy leaves and the unbranched arrangement of the flower cluster (Wagner 
                        *et al.*
                         1999). *Centaurium sebaeoides*
                         has been observed flowering in April. Flowering may be induced by heavy rainfall. Populations are found in dry areas, and plants are more likely to be found following heavy rains (USFWS 1995a). This species appears to be a determinate annual; triggered by declining photo-period, the plant produces seeds and dies (Medeiros 
                        *et al.*
                         1999). Medeiros 
                        *et al.*
                         (1999) noted that in the wild seedlings first appeared in March and April; flowers first appeared in April and May; mature capsules were observed beginning in May and continuing through June; and by the first week of July, most plants were dead. No additional life history information is available for this plant (USFWS 1995a). Historically and currently, 
                        *Centaurium sebaeoides*
                         is known from scattered localities on Kauai, Oahu, Molokai, Lanai, and Maui (Wagner 
                        *et al*. 1999). Currently on Molokai, there are a total of two populations containing thousands of individuals, near Mokio Point on privately owned land and in Kalaupapa National Historical Park on State and federally owned land that is managed by the National Park Service (Chuck Chimera, formerly with Biological Resources Division (BRD), pers. comm. 2000; GDSI 2000; HINHP Database 2000). This species typically grows in volcanic or clay soils or on cliffs in arid coastal areas below 120 m (400 ft) elevation on Molokai (56 FR 55770; Wagner 
                        *et al*. 1999). Associated species include

                         (pauoa) *Ctenitis squamigera*
                         is a short-lived perennial and a member of the wood fern family (Dryopteridaceae) (Wagner and Wagner 1992). It has a rhizome (horizontal stem) 5 to 10 mm (0.2 to 0.4 in) thick, creeping above the ground and densely covered with scales similar to those on the lower part of the leaf stalk. The leaf stalks are densely clothed with tan-colored scales up to 1.8 cm (0.7 in) long and 1 mm (0.04 in) wide. The sori are tan-colored when mature and are in a single row one-third of the distance from the margin to the midrib of the ultimate segments (Degener and Degener 1957). The indusium is whitish before wrinkling, thin, suborbicular with a narra sinus extending about half way, glabrous except for a circular margin which is ciliolate with simple several-celled glandular and nonglandular hairs arising directly from the margin or from the deltoid base (Degener and Degener 1957). 
                        *Ctenitis squamigera*
                         can be readily distinguished from other Hawaiian species of 
                        *Ctenitis*
                         by the dense covering of tan-colored scales on its fronds (Wagner and Wagner 1992). Reproductive cycles, longevity, specific environmental requirements and limiting factors are unknown (USFWS 1998b). Historically, 
                        *Ctenitis squamigera*
                         was recorded from Kauai, Oahu, Molokai, Lanai, Maui, and Hawaii (HINHP Database 2000). It is currently found on Oahu, Lanai, Molokai, and Maui. There is currently a single population with 20 individuals on the island of Molokai in Wawaia Gulch on privately owned land (GDSI 2000; J. Lau, 
                        *in litt*. 2000). On Molokai, this species is found in mesic forest at an elevation of approximately 865 m (254 ft) (J. Lau, 
                        *in litt*. 2000). Associated native plant taxa include

                         a short-lived perennial member of the bellflower family (Campanulaceae), is a shrub with pinnately divided leaves. This species is distinguished from others in this endemic Hawaiian genus by the pinnately lobed leaf margins and the width of the leaf blades. This subspecies is distinguished from the other two subspecies by the shape and size of the calyx lobes which overlap at the base (Lammers 1999). Little is known about the life history of this plant. On Molokai, flowering plants have been observed in July and August. Reproductive cycles, longevity, specific environmental requirements, and limiting factors are unknown (USFWS 1999).

                        (pilo) *Hedyotis mannii,*
                         a member of the coffee family (Rubiaceae), is a short-lived perennial with smooth, usually erect stems 30 to 60 cm (1 to 2 ft) long which are woody at the base and four-angled or -winged. The leaves are opposite, thin in texture and elliptic to 
                        ( print page 83168)
                        sometimes lance-shaped. Stipules (leaf-like appendages), which are attached to the slightly winged leaf stalks where they join and clasp the stem, are triangular. Flowers are arranged in loose clusters up to 30 cm (1 ft) long at the ends of the stems and are either bisexual or female. This species' growth habit; its quadrangular or winged stems; the shape, size, and texture of its leaves; and its dry capsule which opens when mature, separate it from other species of the genus (Wagner 
                        *et al.*
                         1999). Currently, no life history information is available for this species (USFWS 1996a). *Hedyotis mannii*
                         was once widely scattered on Lanai, West Maui, and Molokai (HINHP Database 2000). Currently, this species is extant on Molokai, West Maui, and Lanai. After an absence of 50 years, this species was rediscovered in 1987 by Steve Perlman on private land in Kawela Gulch in TNCH's Kamakou Preserve (GDSI 2000; HINHP Database 2000). Only five plants are known to exist in this area (HINHP Database 2000). *Hedyotis mannii*
                         typically grows on dark, narrow, rocky gulch walls in mesic and perhaps wet forests at 150 to 1,050 m (490 to 3,450 ft) in elevation (Wagner

                         a long-lived perennial member of the aster family (Asteraceae), is a small shrubby tree that usually stands 1.5 to 5 m (5 to 16 ft) tall. This member of an endemic Hawaiian genus differs from other 
                        *Hesperomannia*
                         species in having the following combination of characters, erect to ascending flower heads, thick flower head stalks, and usually hairless and relatively narrow leaves (Wagner 
                        *et al.*
                         1999). This species was observed in flower from April through June and fruit during March and June (USFWS 1998c). No other information is available on reproductive cycles, longevity, specific environmental requirements, and limiting factors (USFWS 1998c). *Hesperomannia arborescens*
                         was formerly known from Lanai, Molokai, and Oahu (HINHP Database 2000). This species is now known from Oahu, Molokai, and Maui. On Molokai, one population of five individuals is known from the State's Olokui NAR (GDSI 2000; HINHP Database 2000). *Hesperomannia arborescens*

                         catastrophic extinction due to random environmental events or reduced reproductive vigor due to this species' limited numbers are significant threats as well (59 FR 14482; HINHP Database 2000). Ischaemum byrone
                         (Hilo ischaemum) *Ischaemum byrone,*
                         a member of the grass family (Poaceae), is a short-lived perennial species with creeping underground and erect stems. 
                        *Ischaemum byrone*
                         can be distinguished from other Hawaiian grasses by its tough outer flower bracts, dissimilar basic flower units, which are awned and two-flowered, and a di- or trichotomously-branching inflorescence (O'Connor 1999). No life history information is currently available for this species (USFWS 1996b). *Ischaemum byrone*
                         was historically distributed on Oahu, Molokai, Maui, and Hawaii Island (59 FR 10305). Currently, this species is found on Molokai, Maui, and Hawaii Island. It has also been reported from unconfirmed sightings on Kauai (HINHP Database 2000). On Molokai, there are a total of 2 populations containing between 100 to 1,000 individuals located in Wailau Valley and the eastern edge of Kikipua on State and privately owned lands (GDSI 2000; HINHP Database 2000). *Ischaemum byrone*

                         (no common name) *Mariscus fauriei,*
                         a member of the sedge family (Cyperaceae), is a perennial plant with somewhat enlarged underground stems and three-angled, single or grouped aerial stems 10 to 50 cm (4 to 20 in) tall. It has leaves shorter than or the same length as the stems 1 to 3.5 mm (0.04 to 0.1 in) wide. This species differs from others in the genus in Hawaii by its smaller size and its narrower, flattened, and more spreading spikelets (Koyama 1999; 59 FR 56333). Currently, no life history information is available for this species (USFWS 1996b). Historically and currently, 
                        *Mariscus fauriei*
                         is found on east Molokai and on the island of Hawaii. This species is no longer extant on Lanai. Currently on Molokai, one population with 20 to 30 plants occurs above Kamiloloa on State-owned land (HINHP Database 2000; GDSI 2000). This species typically grows in 
                        *Diospyros sandwicensis*
                         dominated lowland dry forests, often on a lava substrate, at an elevation of 207 m (680 ft) (HINHP Database 2000; Koyama 1999). Associated species include 
                        *Canthium odoratum, Peperomia*
                         sp. (ala ala wai nui), and

                         (hao) (HINHP Database 2000). The threats to 
                        *Mariscus fauriei*
                         on Molokai are predation and habitat degradation by feral goats and axis deer. Because there is only one known population on Molokai, the species is threatened by the risk of extinction through random environmental events and through reduced reproductive vigor (USFWS 1996b; 59 FR 56333). 
                        ( print page 83169) Marsilea villosa 
                        (ihi ihi) *Marsilea villos,*
                         a member of the family Marsileaceae, is a perennial aquatic to semiaquatic fern similar in appearance to a four-leaved clover. The leaves are born in pairs along a thin rhizome. The leaves and rhizomes vary in pubescence, depending on the aridity of the habitat at the time of development. A hard sporocarp (hard-walled case containing male and female spores) is borne at the base of a leaf pair. The young sporocarp, like the rhizome, is covered with rust-colored hairs which are lost as the sporocarp matures. The plant occurs either in scattered clumps or as a dense interwoven mat, depending on the competition with other species for limited habitat resources. The species is the only member of the genus native to Hawaii and is closely related to 
                        *Marsilea vestita*
                         of the western coast of the United States (USFWS 1996c). *Marsilea villosa*
                         requires periodic flooding for spore release and fertilization, then a decrease in water levels for the young plants to establish, and finally dry soil for sporocarps to mature. Shading reduces vigor of 
                        *Marsilea villosa.*
                         No other life history information is currently available for this species (USFWS 1996c). *Marsilea villosa*
                         was known historically from Oahu, Molokai and Niihau. Currently, it is found only on Oahu and Molokai. On Molokai there are four populations with an unspecified number of individuals located at Kamaka ipo, Ilio Point, Kaiehu Point, and from Kaeo to Mokio on State and privately owned lands (HINHP Database 2000; GDSI 2000). *Marsilea villosa*
                         typically occurs in shallow depressions in clay soil, or lithified sand dunes overlaid with alluvial clay. All reported populations occur at or below 150 m (500 ft) elevation. While 
                        *Marsiliea villosa*
                         can withstand minimal shading, it appears most vigorous growing in open areas. The associated native vegetation of

                        *Marsilea villosa*
                         on Molokai is habitat destruction including the destruction of natural hydrology; the encroachment and competition from naturalized, non-native plants such as

                        *Chamaecrista nictitans*
                         (partridge pea); the disturbance of areas where the plant grows by off-road vehicles or by grazing cattle and axis deer; habitat destruction, degradation, and fragmentation through development, fire, trampling by humans and introduced mammals; catastrophic extinction from random environmental events and reduced reproductive vigor due to few populations and small population sizes (USFWS 1996c; 57 FR 27863). Melicope mucronulata
                         (no common name) *Melicope mucronulata,*
                         a long-lived perennial of the citrus family (Rutaceae) is a small tree up to 13 ft (4 m) tall with oval to elliptic-oval leaves. This species is distinguished from others in the genus by the growth habit, the number of flowers in each flower cluster, the size and shape of the fruit, and the degree of hairiness of the leaves and fruit walls (Stone 
                        *et al.*

                        *Melicope mucronulata*
                         was not relocated until 1983. One population of two individuals was then found two years later in Kupaia on the border of the privately owned Kamakou Preserve and the State's Molokai Forest Reserve in east Molokai (GDSI 2000; HINHP Database 2000; Stone 
                        *et al.*
                         1999). *Melicope mucronulata*
                        occurs on steep, west- or north-facing, dry to mesic, forested lowland slopes at elevations of 670 to 870 m (2,200 to 2,850 ft). Associated native species include

                        (naenae) (HINHP Database 2000). The major threat to the continued existence of this species is catastrophic extinction from random environmental events due to the few extant populations and small number of individuals. Habitat degradation by goats and pigs; predation by goats; and competition with non-native plants, particularly

                         also pose immediate threats to this species (USFWS 1997; 57 FR 20772). Neraudia sericea
                         (no common name) *Neraudia sericea,*
                        a short lived perennial and a member of the nettle family (Urticaceae), is a 3 to 5 m (10 to 16 ft) tall shrub with densely hairy branches. The elliptic or oval leaves have smooth margins or slightly toothed margins on young leaves. The upper leaf surface is moderately hairy and the lower leaf surface is densely covered with irregularly curved, silky gray to white hairs along the veins. The male flowers may be stalkless or have short stalks. The female flowers are stalkless and have a densely hairy calyx that is either toothed, collar-like, or divided into narrow unequal segments. The fruits are achenes with the apical section separated from the basal portion by a deep constriction. Seeds are oval with a constriction across the upper half. 
                        *Neraudia sericea*
                         differs from the other four closely related species of this endemic Hawaiian genus by the density, length, color, and posture of the hairs on the lower leaf surface and by its mostly entire leaf margins (Wagner 
                        *et al.*
                         1999). Additional information on the life history of this plant, reproductive cycles, longevity, specific environmental requirements, and limiting factors are generally unknown (USFWS 1999). *Neraudia sericea*
                         was known historically from Molokai, Lanai, Maui, and Kahoolawe (HINHP Database 2000). Currently, this species is found only on Maui and Molokai. On Molokai, one population of 50 to 100 individuals is known from Makolelau on privately owned land (GDSI 2000; HINHP Database 2000). *Neraudia sericea*

                        (makou) *Peucedanum sandwicense,*
                         a short lived perennial and a member of the parsley family (Apiaceae), is a parsley-scented, sprawling herb. Hollow stems arise from a short, vertical, perennial stem with several fleshy roots. This species is the only member of the genus in the Hawaiian Islands (Constance and Affolter 1999). Additional information on the life history of this plant, reproductive cycles, longevity, specific environmental requirements, and limiting factors are generally unknown (USFWS 1995b). Historically and currently, 
                        *Peucedanum sandwicense*

                        (no common name) *Phyllostegia mannii,*
                         a nonaromatic member of the mint family (Lamiaceae), is a climbing vine with many-branched, four-sided, hairy stems. The opposite, hairy leaves, which are shaped like narrow triangles or narrow triangular ovals have coarsely toothed margins. Clusters of four to six white flowers are arranged in each of several false whorls along an unbranched flowering stem. The fruits are fleshy, dark-green to black nutlets (dry seeds with a hard outer covering). This species is distinguished from others in the genus by its hairiness; its thin, narrow leaves, which are not pinnately divided; and the usually six flowers per false whorl in a terminal inflorescence (Wagner 
                        *et al.*
                         1999). This species was observed with fruit in July (USFWS 1996a). Currently, no additional life history information is available for this species. Historically, 
                        *Phyllostegia mannii*
                         was found from Hanalilolilo to Ohialele on East Molokai and at Ukulele on East Maui. It has not been seen on Maui for over 70 years and is apparently extirpated on that island (USFWS 1996a). This species is now known only from four individuals at Hanalilolilo within Kamakou Preserve on privately owned land (GDSI 2000; HINHP Database 2000). *Phyllostegia mannii*

                         is threatened by habitat destruction and degradation by feral pigs. Because of the small number of individuals, a natural or human-caused environmental event could extirpate all or a significant portion of the population (USFWS 1996a; 57 FR 46325). Plantago princeps
                         (ale) *Plantago princeps,*
                         a short-lived member of the plantain family (Plantaginaceae), is a small shrub or robust perennial herb. This species differs from other native members of the genus in Hawaii by its large branched stems, flowers at nearly right angles to the axis of the flower cluster, and fruits that break open at a point two-thirds from the base. The four varieties, 
                        *anomala, laxiflora, longibracteata,*
                         and 
                        *princeps,*
                         are distinguished by the branching and pubescence of the stems; the size, pubescence, and venation of the leaves; the density of the inflorescence; and the orientation of the flowers (Wagner 
                        *et al.*
                        1999). Little is known about the life history of this plant. Reproductive cycles, longevity, specific environmental requirements, and limiting factors are generally unknown. However, individuals have been observed in fruit from April through September (USFWS 1999). *Plantago princeps*
                         is historically and currently found on Kauai, Oahu, Molokai, and Maui. It is no longer extant on the island of Hawaii.

                         a short-lived perennial and a member of the orchid family (Orchidaceae), is an erect, deciduous herb. The stems arise from underground tubers, the pale green leaves are lance to egg-shaped and the greenish-yellow flowers occur in open spikes. This is the only species of this genus that occurs in the Hawaiian Islands (Wagner

                        *Vaccinium reticulatum*
                         (ohelo ai)(61 FR 53108; USFWS 1999). The primary threats to 
                        *Platanthera holochila*
                         on Molokai are habitat degradation and/or destruction by feral pigs; competition with non-native plants; and a risk of extinction from naturally occurring events and/or reduced reproductive vigor, due to the small number of remaining populations and individuals. Predation by slugs may also be a potential threat to this species (61 FR 53108; USFWS 1999). Schiedea nuttallii
                         (no common name) *Schiedea nuttallii,*
                         a member of the pink family (Caryophyllaceae), is a generally hairless, erect subshrub. This species is distinguished from others in this endemic Hawaiian genus by its habit, length of the stem internodes, length of the inflorescence, number of flowers per inflorescence, smaller leaves, smaller flowers, and smaller seeds (Wagner 
                        *et al.*
                         1999). Little is known about the life history of 
                        *Schiedea nuttallii*. Based on field and greenhouse observations, it is hermaphroditic (flowers contain both sexes) (Weller 
                        *et al.*
                         1990). Plants located close to the Makua rim on Oahu have been under observation for 10 years, and they appear to be long-lived (USFWS 1999). 
                        *Schiedea nuttallii*
                         appears to be an outcrossing species. Under greenhouse conditions, plants fail to set seed unless pollinated, suggesting that this species requires insects for pollination. Seedlings of 
                        *Schiedea*
                         occurring in mesic or wet sites are apparently consumed by introduced slugs and snails. These have been observed feeding on 
                        *S. membranacea,*
                         another mesic forest species occurring on Kauai. In contrast to mesic forest species, 
                        *Schiedea*
                         occurring in dry areas produce abundant seedlings following winter rains, presumably because there are fewer alien consumers in drier sites (USFWS 1999). Fruits and flowers are abundant in the wet season but can be found throughout the year (Kapua Kawelo, U.S. Dept. of Defense, Army Environmental, 
                        *in litt.*
                         1999). Little is known about the life history of this plant. Reproductive cycles, longevity, specific environmental requirements, and limiting factors are unknown. Historically 
                        *Schiedea nuttallii*
                         was known from scattered locations on southeastern Kauai, Oahu, Molokai, and Maui (HINHP Database 2000). Currently, known populations occur on Kauai, Oahu, and Molokai (USFWS 1999). On Molokai one population with 22 individuals of 
                        *Schiedea nuttallii*
                         occurs on the privately owned lands of TNCH's Kamakou Preserve (HINHP Database 2000; GDSI 2000). *Schiedea nuttallii*
                         typically grows in diverse lowland mesic forest, often with 
                        *Metrosideros polymorpha*
                         dominant, at elevations between 415 and 730 m (1,360 and 2,400 ft). On Molokai, the population is found at 354 m (1,160 ft) elevation. Associated plants include

                        i on Molokai is seriously threatened by competition with several non-native plants; predation by the black twig borer, slugs, and snails; and a risk of extinction from naturally occurring events (
                        *e.g.,*
                         landslides) and/or reduced reproductive vigor due to the small number of individuals.(USFWS 1999; 61 FR 53108). Sesbania tomentosa
                         (ohai) *Sesbania tomentosa*, a short lived perennial and a member of the pea family (Fabaceae), is typically a sprawling shrub but may also be a small tree. Each compound leaf consists of 18 to 38 oblong to elliptic leaflets which are usually sparsely to densely covered with silky hairs. The flowers are salmon tinged with yellow, orange-red, scarlet or rarely, pure yellow. 
                        *Sesbania tomentosa*
                         is the only endemic Hawaiian species in the genus, differing from the naturalized 
                        *Sesbania sesban*
                         by the color of the flowers, the longer petals and calyx, and the number of seeds per pod (Geesink 
                        *et al*. 1999). The pollination biology of 
                        *Sesbania tomentosa*
                         is being studied by David Hopper, a graduate student in the Department of Zoology at the University of Hawaii at Manoa. His preliminary findings suggest that although many insects visit 
                        *Sesbania*
                         flowers, the majority of successful pollination is accomplished by native bees of the genus 
                        *Hylaeus*
                         and that populations at Kaena Point on Oahu are probably pollinator limited. Flowering at Kaena Point is highest during the winter-spring rains, and gradually declines throughout the rest of the year (USFWS 1999). Other aspects of this plant's life history are unknown. Currently, 
                        *Sesbania tomentosa*
                         occurs on at least six of the eight main Hawaiian Islands (Kauai, Oahu, Molokai, Kahoolawe, Maui, and Hawaii) and in the Northwestern Hawaiian Islands (Nihoa and Necker). It is no longer extant on Niihau and Lanai (59 FR 56333; GDSI 2000, USFWS 1999; HINHP Database 2000). On Molokai, 
                        *Sesbania tomentosa*
                         is known from eight populations with an estimated total of 100 to 150 individuals. Three of the populations occur from Moomomi to Nenehanaupo and five from Kamiloloa to Makolekau on State and privately owned lands (HINHP Database 2000; GDSI 2000). *Sesbania tomentosa*
                         is found in 
                        *Scaevola sericea*
                         coastal dry shrubland on windswept slopes, sea cliffs and weathered basaltic slopes between sea level and 579 m (0 and 1,900 ft) elevation (HINHP Database 2000). Associated plant species include 
                        *Lipochaeta integrifolia, Jacquemontia sandwicensis, Sida fallax,*
                         and

                         (HINHP Database 2000; USFWS 1999). The primary threats to 
                        *Sesbania tomentosa*
                         on Molokai are competition with various non-native plant species such as 
                        *Lantana camara,*
                         and grass species; habitat degradation by feral cattle; lack of adequate pollination; seed predation by rats, mice and, potentially, non-native insects; and destruction by random environmental events (
                        *e.g.,*
                         fire) and by human activities (
                        *e.g.,*
                         use of off-road vehicles) (59 FR 56333; USFWS 1999). Silene lanceolata
                         (no common name) *Silene lanceolata,*
                         a member of the pink family, is an upright, perennial plant with stems 15 to 50 cm (6 to 20 in) long, which are woody at the base. The narrow leaves are smooth except for a fringe of hairs near the base. Flowers are arranged in open clusters. The flowers are white with deeply-lobed, clawed petals. The capsule opens at the top to release reddish-brown seeds. This species is distinguished from 
                        *S. alexandri,*
                         the only other member of the genus found on Molokai, by its smaller flowers and capsules and its stamens, which are shorter than the sepals (Wagner 
                        *et al*. 1999). Currently, no life history information is available for this species (USFWS 1996a). The historical range of 
                        *Silene lanceolata*
                         includes five Hawaiian 
                        ( print page 83172)
                        Islands: Kauai, Oahu, Molokai, Lanai, and Hawaii Island. 
                        *Silene lanceolata*
                         is presently extant on the islands of Molokai, Oahu, and Hawaii. On Molokai, a single population of approximately 100 individuals was found in 1987 on private land near Puu Kolekole (K. Wood, 
                        *in litt.*
                         1999; GDSI 2000; USFWS 1996a). On Molokai, this species grows on cliff faces and ledges of gullies in dry to mesic shrubland at an elevation of about 800 m (2,600 ft) (USFWS 1996a). Associated native plant species include 
                        *Dodonea viscosa, Styphelia tameiameiae,*
                         and

                        *in litt.*
                         1999). Habitat destruction by feral ungulates (goats and pigs), wildfires, and competition by invading non-native plants are immediate threats to

                         on Molokai (57 FR 46325; USFWS 1996a). Spermolepis hawaiiensis
                         (no common name) *Spermolepis hawaiiensis,*
                         a member of the parsley family (Apiaceae), is a slender annual herb with few branches. Its leaves, dissected into narrow, lance-shaped divisions, are oblong to somewhat oval in outline and grow on stalks. Flowers are arranged in a loose, compound umbrella-shaped inflorescence arising from the stem, opposite the leaves. 
                        *Spermolepis hawaiiensis*
                         is the only member of the genus native to Hawaii. It is distinguished from other native members of the family by being a non-succulent annual with an umbrella-shaped inflorescence (Constance and Affolter 1999). Little is known about the life history of 
                        *Spermolepis hawaiiensis.*
                         Reproductive cycles, longevity, specific environmental requirements, and limiting factors are unknown (USFWS 1999). Historically, 
                        *Spermolepis hawaiiensis*
                         was known from Kauai, Oahu, Lanai and the island of Hawaii (HINHP Database 2000). Currently, it is extant on Kauai, Oahu, Molokai, Lanai, Maui, and Hawaii (GDSI 2000; 59 FR 56333; HINHP Database 2000). On Molokai, there is one known population with approximately 600 individuals on privately owned land in Kamalo (HINHP Database 2000; GDSI 2000; USFWS 1999). *Spermolepis hawaiiensis*
                         is known from shady spots in 
                        *Dodonea viscosa*
                         lowland dry shrubland, at an elevation of 219 m (720 ft). Associated plant species include

                         (HINHP Database 2000; USFWS 1999). The primary threats to 
                        *Spermolepis hawaiiensis*
                         on Molokai are habitat degradation by feral goats; competition with various non-native plants such as 
                        *Melinis minutiflora, Lantana camara*, and grasses; and habitat destruction and extinction due to natural environmental events such as erosion, landslides, and rockslides due to natural weathering (59 FR 56333; USFWS 1999). Vigna o-wahuensis
                         (no common name) *Vigna o-wahuensis*, a member of the pea family (Fabaceae), is a slender twining perennial herb with fuzzy stems. Each leaf is made up of three leaflets which vary in shape from round to linear, and are sparsely or moderately covered with coarse hairs. Flowers, in clusters of one to four, have thin, translucent, pale yellow or greenish yellow petals. The two lowermost petals are fused and appear distinctly beaked. The sparsely hairy calyx has asymmetrical lobes. The fruits are long slender pods that may or may not be slightly inflated and contain 7 to 15 gray to black seeds. This species differs from others in the genus by its thin yellowish petals, sparsely hairy calyx, and thin pods which may or may not be slightly inflated (Geesink 
                        *et al.*
                         1999). Additional information on the life history of this plant, reproductive cycles, longevity, specific environmental requirements, and limiting factors are generally unknown (USFWS 1999). Historically, 
                        *Vigna o-wahuensis*
                         was known from Niihau, Oahu, and Maui (HINHP Database 2000). Currently, 
                        *Vigna o-wahuensis*
                         is known from the islands of Molokai, Lanai, Kahoolawe, Maui, and Hawaii (HINHP Database 2000). There are no currently known populations on Niihau or Oahu. On Molokai, two populations with approximately 16 individuals occur on privately owned lands at Onini Gulch and Makolelau (GDSI 2000). On Molokai, 
                        *Vigna o-wahuensis*
                         occurs in dry to mesic grassland and shrubland from 207 to 256 m (680 to 840 ft) in elevation (Geesink

                         on Molokai are competition with various non-native plant species; and a risk of extinction due to random environmental events (primarily fire), and/or reduced reproductive vigor due to the small number of existing populations and individuals (USFWS 1999; 59 FR 56333). Zanthoxylum hawaiiense
                         (ae) *Zanthoxylum hawaiiense*, a long lived perennial, is a medium-size tree with pale to dark gray bark, and lemon-scented leaves in the rue family (Rutaceae). Alternate leaves are composed of three small triangular-oval to lance-shaped, toothed leaves (leaflets) with surfaces usually without hairs. 
                        *Zanthoxylum hawaiiense*
                         is distinguished from other Hawaiian members of the genus by several characters: three leaflets all of similar size, one joint on lateral leaf stalk, and sickle-shape fruits with a rounded tip (Stone 
                        *et al.*
                         1999). Additional information on the life history of this plant, reproductive cycles, longevity, specific environmental requirements, and limiting factors are generally unknown (USFWS 1996b). Historically, 
                        *Zanthoxylum hawaiiense*
                         was known from the islands of Kauai, Molokai, Lanai, southern and southwestern slopes of Haleakala on Maui, and Hawaii. Currently,

                         (40 FR 27823) of our acceptance of the Smithsonian report as a petition within the context of Section 4(c)(2) (now Section 4(b)(3)) of the Act, and giving notice of our intention to review the status of the plant taxa named therein. As a result of that review, on June 16, 1976, we published 
                        ( print page 83174)
                        a proposed rule in the 
                        **Federal Register**
                         (41 FR 24523) to determine endangered status pursuant to Section 4 of the Act for approximately 1,700 vascular plant taxa, including all of the above taxa except 
                        *Labordia triflora.*
                         The list of 1,700 plant taxa was assembled on the basis of comments and data received by the Smithsonian Institution and the Service in response to House Document No. 94-51 and the July 1, 1975, 
                        **Federal Register**
                         publication. General comments received in response to the 1976 proposal are summarized in an April 26, 1978,

                         publication (43 FR 17909). In 1978, amendments to the Act required that all proposals over two years old be withdrawn. A one-year grace period was given to proposals already over two years old. On December 10, 1979, we published a notice in the 
                        **Federal Register**
                         (44 FR 70796) withdrawing the portion of the June 16, 1976, proposal that had not been made final, along with four other proposals that had expired. The Service published updated notices of review for plants on December 15, 1980 (45 FR 82479), September 27, 1985 (50 FR 39525), February 21, 1990 (55 FR 6183), September 30, 1993 (58 FR 51144), and February 28, 1996 (61 FR 7596), and September 19, 1977 (62 FR 49398). A summary of the status categories for these 40 plant species in the 1980-1996 notices of review can be found in Table 4(a). We listed the 40 species as endangered or threatened between 1991 and 1999. A summary of the listing actions can be found in Table 4(b). Table 4(

                        ( print page 83175) Section 4(a)(3) of the Act, as amended, and implementing regulations (50 CFR 424.12) require that, to the maximum extent prudent and determinable, the Secretary designate critical habitat at the time the species is determined to be endangered or threatened. Our regulations (50 CFR 424.12(a)(1)) state that designation of critical habitat is not prudent when one or both of the following situations exist: (1) The species is threatened by taking or other human activity, and identification of critical habitat can be expected to increase the degree of threat to the species, or (2) such designation of critical habitat would not be beneficial to the species. At the time each plant was listed, we determined that designation of critical habitat was prudent for one of these plants (Labordia triflora) and not prudent for the other 39 plants because it would not benefit the plant and/or would increase the degree of threat to the species. The not prudent determinations were challenged in

                        *Babbitt*. 2 F. Supp. 2d 1280 (D. Haw. 1998). On March 9, 1998, the United States District Court for the District of Hawaii (the Court) directed us to review the prudency determinations for 245 listed plant species in Hawaii, including these 39 species. Among other things, the Court held that in most cases we did not sufficiently demonstrate that the species are threatened by human activity or that such threats would increase with the designation of critical habitat. The Court also held that we failed to balance any risks of designating critical habitat against any benefits (

 Regarding our determination that designating critical habitat would have no additional benefits to the species above and beyond those already provided through the section 7 consultation requirement of the Act, the Court ruled that we failed to consider the specific effect of the consultation requirement on each species (
                        *Id*. at 1286-88). In addition, the Court stated that we did not consider benefits outside of the consultation requirements. In the Court's view, these potential benefits include substantive and procedural protections. The Court 
                        ( print page 83176)
                        held that substantively, designation establishes a “uniform protection plan” prior to consultation and indicates where compliance with section 7 of the Act is required. Procedurally, the Court stated that the designation of critical habitat educates the public and State and local governments and affords them an opportunity to participate in the designation (
                        *Id*. at 1288). The Court also stated that private lands may not be excluded from critical habitat designation even though section 7 requirements apply only to Federal agencies. In addition to the potential benefit of informing the public and State and local governments of the listing and of the areas that are essential to the species' conservation, the Court found that there may be Federal activity on the private property in the future, even though no such activity may be occurring there at the present (
                        *Id*. at 1285-88). On August 10, 1998, the Court ordered us to publish proposed critical habitat designations or non-designations for at least 100 species by November 30, 2000, and to publish proposed designations or non-designations for the remaining 145 species by April 30, 2002 (24 F. Supp. 2d 1074). At the time we listed 
                        *Labordia triflora*
                         (64 FR 48307) we determined that designation of critical habitat was prudent and that we would develop critical habitat designations for this taxon, along with nine others, at the same time we developed designations for the 245 Hawaiian plant species. This timetable was challenged in 
                        *Conservation Council for Hawaii*
                         v. 
                        *Babbitt.*
                         Civ. No. 99-00283 HG (D. Haw. Aug. 19, 1999, Feb. 16, 2000, and March 28, 2000). The Court agreed, however, that it was reasonable for us to integrate these ten Maui Nui (Maui, Lanai, Molokai, and Kahoolawe) plant taxa into the schedule established for designating critical habitat for the other 245 Hawaiian plants, and ordered us to publish proposed critical habitat designations for the ten Maui Nui species by November 30, 2000, and to publish final critical habitat designations by November 30, 2001. This notice responds to the Court orders. On November 30, 1998, we published a notice in the 
                        **Federal Register**
                         requesting public comments on our reevaluation of whether designation of critical habitat is prudent for the 245 Hawaiian plants at issue (63 FR 65805). The comment period closed on March 1, 1999, and was reopened from March 24, 1999, to May 24, 1999 (64 FR 14209). We received over 100 responses from individuals, non-profit organizations, the State of Hawaii's Division of Forestry and Wildlife, county governments, and Federal agencies (U.S. Department of Defense—Army, Navy, Air Force). Only a few responses offered information on the status of individual plant species or on current management actions for one or more of the 245 Hawaiian plants. While many of the respondents expressed support for the designation of critical habitat for 245 Hawaiian plants, more than 80 percent opposed the designation of critical habitat for these plants. In general, these respondents opposed designation because they believed it will cause economic hardship, chill cooperative projects, polarize relationships with hunters, or potentially increase trespass or vandalism on private lands. In addition, commenters also cited a lack of information on the biological and ecological needs of these plants which, they suggested, may lead to designation based on guesswork. The respondents who supported the designation of critical habitat cited that designation will: provide a uniform protection plan for the Hawaiian Islands; promote funding for management of these plants; educate the public and State government; and protect partnerships with landowners and build trust. On February 18, 2000, we mailed letters to over 100 landowners on the island of Molokai requesting any information considered germane to the management of any of the 255 plants on his/her property, and containing a copy of the November 30, 1998, 
                        **Federal Register**
                         notice, a map showing the general locations of the plants that may be on his/her property, and a handout containing general information on critical habitat. We received 25 written responses to our landowner mailing with varying types of information on their current land management activities. Some landowners reported that they are not conducting conservation management actions on their lands while others provided information on various activities such as fencing, weeding, ungulate control, hunting, control of human access, scientific research, fire control, and propagation and/or planting of native plants. We held one open house on the island of Molokai, at the Mitchell Pauole Community Center, on March 15, 2000, to meet one-on-one with local landowners and other interested members of the public. A total of 14 people attended the open house. In addition we met with Maui County Division of Forestry and Wildlife staff and discussed their management activities on Molokai. On November 7, 2000, we published the first of the court-ordered prudency determinations and proposed critical habitat designations for Kauai and Niihau plants (65 FR 66808). The prudency determinations and proposed critical habitat designations for Maui and Kahoolwe plants were published on December 18, 2000 (65 FR 79192), and for Lanai plants on December 27, 2000. In those proposals we determined that critical habitat was prudent for 19 species (
                        *Adenophorus periens, Alectryon macrococcus, Centarium sebaeoides, Ctenitis squamigera, Cyanea grimesiana*
                         ssp. 
                        *grimesiana, Diellia erecta, Hedyotis mannii, Hesperomannia arborescens, Ischaemum byrone, Melicope mucronulata, Neraudia sericea, Peucedanum sandwicense, Plantago princeps, Platanthera holochila, Schiedea nuttallii, Sesbania tomentosa, Spermolepis hawaiiensis, Vigna-owahuensis,*
                         and 
                        *Zanthoxylum hawaiiense*) that occur on Molokai as well as on Kauai, Niihau, Maui, Kahoolawe, and/or Lanai. 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” 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 “* * * the 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 
                        ( print page 83177)
                        of those physical or biological features that were the basis for determining the habitat to be critical.” Aside from the added protection that may be provided under section 7, the Act does not provide other forms of protection to lands designated as critical habitat. Because consultation under section 7 of the Act does not apply to activities on private or other non-Federal lands that do not involve a Federal nexus, critical habitat designation would not afford any additional protections under the Act against such activities. In order to be included in a critical habitat designation, the habitat must first be “essential to the conservation of the species.” Critical habitat designations identify, to the extent known using the best scientific and commercial data available, habitat areas that provide essential life cycle needs of the species (
                        *i.e.*, areas on which are found the primary constituent elements, as defined at 50 CFR 424.12(b)). Section 4 requires that we designate critical habitat at the time of listing and based on what we know at the time of the designation. When we designate critical habitat at the time of listing or under short court—ordered deadlines, we will often not have sufficient information to identify all areas of critical habitat. We are required, nevertheless, to make a decision and thus must base our designations on what, at the time of designation, we know to be critical habitat. Within the geographic area occupied by the species, we will designate only areas currently known to be essential. Essential areas should already have the features and habitat characteristics that are necessary to sustain the species. We will not speculate about what areas might be found to be essential if better information became available, or what areas may become essential over time. 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. Within the geographic area occupied by the species, we will not designate areas that do not now have the primary constituent elements , as defined at 50 CFR 424.12(b), that provide essential life cycle needs of the species. Our regulations state that, “The Secretary shall designate as critical habitat areas outside the geographic area presently occupied by the 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. The Service's Policy on Information Standards Under the Endangered Species Act, published in the 
                        **Federal Register**
                         on July 1, 1994 (Vol.59, p. 34271), provides criteria, establishes procedures, and provides guidance to ensure that decisions made by the Service represent the best scientific and commercial data available. It requires Service 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 a recovery plan, articles in peer-reviewed journals, conservation plans developed by states and counties, scientific status surveys and studies, and biological assessments or other unpublished materials (
                        *i.e.*, gray literature). Habitat is often dynamic, and species may move from one area to another over time. Furthermore, we recognize that designation of critical habitat may not include all of the habitat areas that may eventually be determined to be necessary for the recovery of the species. For these reasons, all should 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 section 7(a)(2) jeopardy standard and the section 9 take prohibition, 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. A. Prudency Redeterminations As previously stated, 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 of the 20 species at issue, we analyzed the potential threats and benefits for each species in accordance with the court's order. Due to low numbers of individuals and/or populations and their inherent immobility, the 20 plants may be vulnerable to unrestricted collection, vandalism, or disturbance. We have examined the evidence currently available for each of these taxa and have found specific evidence of taking, vandalism, collection or trade for one species of 
                        *Pritchardia*, the native palm on Molokai. At the time of listing, we determined that designation of critical habitat was not prudent for 
                        *Pritchardia munroi*
                         because it would increase the degree of threat from vandalism or collecting, and would provide no benefit (57 FR 46325). Recently we received information on the commercial trade in palms conducted through the internet (Grant Canterbury, USFWS, 
                        *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 munroi*. 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 Molokai. First, it is easy to identify, and second, it may be 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 this species of palm 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 this species more vulnerable to incidents of vandalism or collection, and therefore, make recovery more difficult and contribute to the decline of this species (57 FR 46325). 
                        ( print page 83178) In addition, we believe that designation would not provide significant benefits that would outweigh these increased risks. First, 
                        *Pritchardia munroi*
                         does not occur on Federal land. The private land where it is found is zoned for agriculture, though the single tree has been fenced (HINHP Database 2000). In addition, this species is found in a small ravine in an area that is remote and inaccessible to standard vehicles. It is, therefore, unlikely that the land on which it is found will be developed. Since there does not appear to be any actions in the future that would involve a Federal agency, designation of critical habitat would not provide any additional protection to the species that it does not already have through listing alone. If however in the future any Federal involvement did occur, such as through the permitting process or funding by the U.S. Department of Agriculture, the U.S. Department of Interior, the Corps through section 404 of the Clean Water Act, the U.S. Federal Department of Housing and Urban Development or the Federal Highway Administration, the actions would be subject to consultation under section 7 of the Act. We acknowledge that critical habitat designation, in some situations, may provide some value to the species, for example, by identifying areas important for conservation and calling attention to those areas in need of special protection. However, for this species, 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 propose that designation of critical habitat for 
                        *Pritchardia munroi*
                         is not prudent. We examined the evidence for the other 19 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 19 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, which 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 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 19 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 destroys or adversely affects critical habitat. At least four of these species are reported from Federal lands or lands under Federal jurisdiction (
                        *Canavalia molokaiensis, Centaurium sebaeoides, Peucedanum sandwicense,*
                         and 
                        *Tetramalopium rockii*) (see Table 3), where most actions would be subject to section 7. While a majority of these species 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 be unlikely to change the section 7 consultation outcome because 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 also may be some educational or informational benefits to the designation of critical habitat. Educational benefits include the notification of land owners, land managers, and the general public of the importance of protecting the habitat of these species and dissemination of information regarding their essential habitat requirements. Therefore, we propose that critical habitat is prudent for 19 plant species: 
                        *Bidens wiebkei, Brighamia rockii, Canavalia molokaiensis, Clermontia oblongifolia*
                         ssp. 
                        *brevipes, Cyanea dunbarii, Cyanea mannii, Cyanea procera, Hibiscus arnottianus*
                         ssp. 
                        *immaculatus, Lysimachia maxima, Mariscus fauriei, Marsilea villosa, Melicope reflexa, Phyllostegia mannii, Schiedea lydgatei, Schiedea sarmentosa, Silene alexandri, Silene lanceolata, Stenogyne bifida,*
                         and 
                        *Tetramolopium rockii.* B. Primary Constituent Elements In accordance with section 4(b)(2) 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 that are essential to the conservation of the species and that may require special management considerations or protection. Such requirements 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. As stated above in the discussion about each of the 32 species, very little is known about the specific physical and biological requirements of these species. As such, we are proposing to define the primary constituent elements on the basis of general habitat features of the areas in which the plant species are currently found, such as the type of plant community and their physical location (
                        *e.g.*, steep rocky cliffs, talus slopes, stream banks) and elevation. Therefore, the descriptions of the physical elements of the locations of each of these species and the plant community associated with the species, as described in the 
                        **SUPPLEMENTARY INFORMATION:**
                          
                        *Discussion of the Plant Taxa*
                         section above, constitute the primary constituent elements for these species. C. Methods for Selection of Areas for Proposed Critical Habitat Designations Critical habitat is defined as the specific areas within the geographic area occupied by the species, at the time it is listed in accordance with the provisions of section 4 of the Act, on which are found those physical and biological features (I) essential to the conservation of the species and (II) which may require special management considerations or protection (16 U.S.C. 1532(5)(A)(i)). As discussed above, very little is known about the specific physical and biological requirements of most of these 40 species. Therefore, we have defined primary constituent elements based on the general habitat features of the areas in which they currently occur such as the type of plant community the plants are growing in, their physical location (
                        *e.g.*, steep rocky cliffs, talus slopes, stream banks), and elevation. The areas we are proposing to designate as critical habitat provide some or all of the habitat components 
                        ( print page 83179)
                        essential for the conservation of the plant species. Critical habitat may also include areas outside the geographic area presently occupied by a species upon determination that such areas are essential to the conservation of the species (16 U.S.C. 1532 (5)(A)(ii)). This may include, for example, potentially suitable unoccupied habitat that is important to the recovery of the species. However, we have not included such areas in the proposed designations for these species because of our limited knowledge of the historical range (the geographical area outside the area presently occupied by the species), and our lack of more detailed information on the specific physical or biological features essential for the conservation of the species that would be needed, for instance, to determine where to reintroduce a species. The historical (pre-1970) or even post-1970 records for a species may be based on herbarium specimens that contain only the most rudimentary collection information, such as only the name of the island from which the specimen was collected or a general place name (
                        *e.g.,*
                         East Molokai, Kamakou, Pelekunu). In the main Hawaiian Islands, climatic and ecological conditions such as rainfall, elevation, slope, aspect, etc., may vary dramatically within a relatively short distance. Therefore a simple place name does not provide adequate information on the physical and biological features that may have occurred there or may occur there now. The unpredictable distribution of Hawaiian plant species also makes it difficult to designate potentially suitable unoccupied habitat. For example, currently a species may be known from northern and southern (or eastern and western) locations on an island but not from intervening locations in similar habitat. Based on the best available information, we are unable to determine whether a species once occurred in the intervening areas and disappeared from there prior to Polynesian or European times (thus never having been collected or documented there) or simply never occurred there. We consider reintroduction (the planting of propagated individuals or seedlings into an area) to be an acceptable method to try to achieve plant species recovery. However, native plant reintroductions are difficult and successful efforts are not common. We do not know enough about these 40 species to identify areas where reintroductions are likely to be successful. We will continue to support experimental efforts to reintroduce species that may eventually provide us with additional information on the physical and biological features essential to the conservation of these species, and thus, may eventually result in identification of unoccupied habitat for future designation. As required by the Act and regulations (section 4 (b) (2) and 50 CFR 424.12) we used the best scientific information available to determine areas that contain those physical and biological features that are essential for the survival and recovery of the 40 plant species. This information included site-specific species information from the Hawaii Natural Heritage Program (HINHP) and our rare plant database, species information from the Center for Plant Conservation's (CPC) rare plant monitoring database housed at the University of Hawaii's Lyon Arboretum, recent biological surveys and reports, our recovery plans for 39 of these 40 species, discussions with botanical experts, and recommendations (see below) from the Hawaii and Pacific Plant Recovery Coordinating Committee (HPPRCC) (CPC, 
                        *in litt.*
                         1999; HINHP Database 2000, HPPRCC 1998, USFWS 1995a, 1995b, 1996a, 1996b, 1996c, 1997, 1998a, 1998b, 1998c; 1999). 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*
                         (USFWS 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 findings may also lead to additional refinements (HPPRCC 1998). Because the HPPRCC identified essential habitat areas for all listed, proposed, and candidate plant species and evaluated species of concern to determine if essential habitat areas would provide for their habitat needs as well, the HPPRCC's mapping of habitat is distinct from the regulatory designation of critical habitat, as defined by the Act. While these habitat maps are a planning tool to focus conservation efforts on the areas that may be most important to the conservation of Hawaii's listed plant species, as well as other plant species of concern, it does not substitute for the more exacting regulatory process of designating critical habitat. Therefore, the proposed critical habitat designations in this proposed rule do not include all of the habitat, particularly unoccupied habitat, identified by the HPPRCC. For these plant species from Molokai, currently occupied habitat was examined and critical habitat boundaries were delineated in such a way that locations with a high density of endangered and threatened plants could be depicted clearly (multi-species units). However, these multi-species critical habitat units are not homogenous or uniform in nature. Critical habitat units often encompassed a number of plant community types. To examine plant occurrences, every current (post-1970) location of every species was delineated within a 536 m (1,760 ft) radius circle with an additional 50 m (164 ft) added to the radius of each location, in order to insure enough area to provide for the proper ecological functioning of the habitat immediately supporting the plant, for a total of 586 m (1,924 ft) radius. The 536 m (1,760 ft) radius is consistent with the accuracy of the mapped locations of the plant(s), and is based on the standard mapping methodology for rare species used by the HINHP (1996). The additional 50 m (164 ft) is consistent with the guidelines identified in the recovery plans for these species for minimum-sized exclosures for rare plants (USFWS 1995a, 1995b, 1996a, 1996b, 1996c, 1997, 1998a, 1998b, 1998c, 1999). In cases where there were isolated species locations, a circular area with a radius of roughly 586 m (1,924 ft) is proposed as critical habitat (HINHP 1996; USFWS 1995a, 1995b, 1996a, 1996b, 1996c, 1997, 1998a, 1998b, 1998c, 1999). The manner in which we delineated each multi-species proposed critical habitat unit is described below. —Known current locations of each species were delineated using the guidelines explained above (Figure 1(a)). —The perimeter boundaries of individual circular areas were connected to form unit area boundaries (Figure 1(b)). —Unit area boundaries were delineated to follow significant topographic features (50 CFR 424.12(c)) such as coastlines, ridgelines, and valleys (Figure 1(c)). 
 
    These delineation methods were used to facilitate identification of boundary lines and to aid in implementation of on-the-ground conservation measures. In delineating critical habitat units we made an effort to avoid developed areas such as towns, agricultural lands, and other lands unlikely to contribute to the conservation of these 32 species. Within the critical habitat boundaries, adverse modification generally would only occur if the primary constituent elements are affected. Therefore, not all activities within critical habitat would trigger an adverse modification conclusion. Existing features and structures within proposed areas, such as buildings, roads, aqueducts, telecommunications equipment, arboreta and gardens, heiaus (indigenous places of worship or shrines), and other man-made features, do not contain, and are not likely to develop, constituent elements. Therefore, unless a Federal action related to such features or structures indirectly affected nearby habitat containing the primary constituent elements, operation and maintenance of such features or structures generally would not be impacted by the designation of critical habitat. All currently occupied sites containing one or more of the primary constituent elements considered essential to the conservation of these 40 plant species were examined to determine if additional special management considerations or protection are required above those currently provided. We reviewed all available management information on these plants at these sites including published reports and surveys; annual performance reports; forestry management plans; grants; memoranda of understanding and cooperative agreements; State of Hawaii, Division of Forestry and Wildlife (DOFAW) planning documents; internal letters and memos; biological assessments and environmental impact statements; and, section 7 consultations. Additionally, each public (
                        *i.e.,*
                         any county, state, or Federal government office holdings) and private landowner on Molokai with a known occurrence of one of the 40 species was contacted by mail. We reviewed all information received during the public comment period, in response to our landowner mailing and at an open house held in Kaunakakai, Molokai on March 15, 2000. When clarification was required on the information provided to us, we followed up with a telephone contact. Pursuant to the definition of critical habitat in section 3 of the Act, any area so designated must also require “special managment considerations or protections.” Adequate special management or protection is provided by a legally operative plan that addresses the maintenance and improvement of the essential elements and provides for the long-term conservation of the species. The Service considers a plan adequate when it meets all of the following three criteria: (1) The plan provides a conservation benefit to the species (
                        *i.e.,*
                         the plan must maintain or provide for an increase in the species' population or the enhancement or restoration of its habitat within the area covered by the plan; (2) the plan provides assurances that the management plan will be implemented (
                        *i.e.,*
                         those responsible for implementing the plan are capable of accomplishing the objectives, have an implementation schedule and/or have adequate funding to implement the management plan); and, (3) the plan provides assurances the conservation plan will be effective (
                        *i.e.,*
                         it identifies biological goals, has provisions for reporting progress, and is of a duration sufficient to implement the plan and achieve the plan's goals and objectives). If an area is covered by a plan that meets these criteria, it does not constitute critical habitat as defined by the Act. In determining and weighing the relative significance of the threats that would need to be addressed in 
                        ( print page 83181)
                        management plans or agreements, we considered the following: —The factors that led to the listing of the species, as described in the final rules for listing each of the species. For all or nearly all endangered and threatened plants in Hawaii, the major threats include adverse impacts due to non-native plant and animal species. Direct browsing, digging, and trampling by ungulates, including pigs, goats, cattle, sheep, and deer, and direct competition from non-native plants have led to the decline of Hawaii's native flora (Cuddihy and Stone 1990; Loope 1998; Scott 
                        *et al.*
                         1986; Smith 1985; Stone 1985; USFWS 1995a, 1995b, 1996a, 1996b, 1996c, 1997, 1998a, 1998b, 1998c, 1999; Vitousek 1992; Wagner 
                        *et al.*
                         1985). Ungulate activity in most areas results in an increase of non-native plants because most of these non-native plants are able to colonize newly disturbed areas more quickly and effectively than Hawaii's native plants (Cuddihy and Stone 1990; Mack 1992; Scott 
                        *et al.*
                        1986; Smith 1985; Tunison 
                        *et al.*
                         1992; USFWS 1995a, 1995b,1996a, 1996b, 1996c, 1997, 1998a, 1998b, 1998c; 1999). —The recommendations from the HPPRCC in their 1998 report to the Service (“Habitat Essential to the Recovery of Hawaiian Plants”). As summarized in this report, recovery goals for endangered Hawaiian plant species cannot be achieved with ungulates (
                        *e.g.,*
                         pigs, goats, deer, and sheep) present in Essential Habitat Areas. —The management actions needed for assurance of survival and ultimate recovery of Hawaii's endangered plants. These actions are described in the Service's recovery plans for 39 of the 40 species (USFWS 1995a, 1995b, 1996a, 1996b, 1996c, 1997, 1998a, 1998b, 1998c, 1999), in the 1998 HPPRCC report to the Service (HPPRCC 1998), and in various other documents and publications relating to plant conservation in Hawaii (Cuddihy and Stone 1990; Mueller-Dombois 1985; Smith 1985; Stone 1985; Stone 
                        *et al.*
                         1992). These actions include, but are not limited to, the following: (1) Feral ungulate control; (2) non-native plant control; (3) rodent control; (4) invertebrate pest control; (5) fire control; (6) maintenance of genetic material of the endangered and threatened plants species; (7) propagation; reintroduction, and/or augmentation of existing populations into areas deemed essential for the recovery of these species; (8) ongoing management of the wild, outplanted, and augmented populations; (9) habitat management and restoration in areas deemed essential for the recovery of these species; and (10) monitoring of the wild, outplanted, and augmented populations. In general, taking all of the above recommended management actions into account, the following management actions are ranked in order of importance. It should be noted, however, that, on a case-by-case basis, some of these actions may rise to a higher level of importance for a particular species or area, depending on the biological and physical requirements of the species and the location(s) of the individual plants: —Feral ungulate control; —Non-native plant control; —Rodent control; —Invertebrate pest control; —Fire control; —Maintenance of genetic material of the endangered and threatened plant species; —Propagation; reintroduction and/or augmentation of existing populations into areas deemed essential for the recovery of the species; —Ongoing management of the wild, outplanted and augmented populations; —Maintenance of natural pollinators and pollinating systems, when known; —Habitat management and restoration in areas deemed essential for the recovery of the species; —Monitoring of the wild, outplanted and augmented populations; —Rare plant surveys; —Control of human activities/access. As shown in Table 3, these 40 species of plants occur on Federal, State, and private lands on the island Molokai. In response to our two public notices, letters to the landowners, open houses, and meetings, along with information in our files, we received varying amounts and various types of information on the conservation management actions occurring on these lands. Some landowners reported that they are not conducting conservation management actions on their lands while others provided information on various activities such as fencing, weeding, ungulate control, hunting, control of human access, scientific research, fire control, and propagation and/or planting of native plants. Four species (
                        *Canavalia molokaiensis, Centaurium sebaeiodes, Peucedanum sandwicense, Tetramolopium rockii*) are reported from Kalaupapa National Historical Park, Molokai (GDSI 2000; HINHP Database 2000). This national historical park, which is found on state-owned land, is managed by the National Park Service under a cooperative agreement between the State of Hawaii and the National Park Service (Gary Barbano, National Park Service, pers. comm. 2000). Although the National Park Service conducts some conservation management actions on these lands and provides access to others who are conducting such activities, there are no comprehensive management plans for the long-term conservation of endangered and threatened plants on these lands and no assurances that management actions will be implemented. Therefore, we can not at this time find that management on this land under Federal jurisdiction is adequate to preclude a proposed designation of critical habitat. Twenty-three species (
                        *Adenophorous periens, Alectryon macrococcus, Brighamia rockii, Canavalia molokaiensis, Clermontia oblongifolia ssp. brevipes, Ctenitis squamigera, Cyanea mannii, Cyanea procera, Diellia erecta, Hedyotis mannii, Lysimachia maxima, Marsilea villosa, Melicope mucronulata, Peucedanum sandwicense, Phyllostegia mannii, Plantago princeps, Platanthera holochila, Schiedea nuttallii, Schiedea sarmentosa, Stenogyne bifida, Tetramolopium rockii, Vigna o-wahuense, Zanthoxylum hawaiiense*) are reported from The Nature Conservancy's Moomomi, Kamakou, and Pelekunu Preserves which are located on the northwest coast (Moomomi) and in the East Molokai mountains (Kamakou and Pelekunu) (GDSI 2000; HINHP database 2000; The Nature Conservancy of Hawaii (TNCH) 1993, 1994a, 1994b, 1997, 1999a, 1999b, 1999c). Two of the preserves (Moomomi and Pelekunu) are owned by The Nature Conservancy while Kamakou was established by a grant of perpetual conservation easement from the private landowner to TNCH. All three preserves are included in the state's Natural Area Partnership (NAP) program which provides matching funds for the management of private lands that have been permanently dedicated to conservation (TNCH 1993, 1994a, 1994b, 1997, 1999a, 1999b, 1999c). Under the NAP program, the State of Hawaii provides matching funds on a two-for-one basis for management of private lands dedicated to conservation. In order to qualify for this program, the land must be dedicated in perpetuity through transfer of fee title or a conservation easement to the State or a cooperating entity. The land must be managed by the cooperating entity or a 
                        ( print page 83182)
                        qualified landowner according to a detailed management plan approved by the Board of Land and Natural Resources. Once approved, the six-year partnership agreement between the State and the managing entity is automatically renewed each year so that there is always six years remaining in the term, although the management plan is updated and funding amounts are re-authorized by the board at least every six years. By April 1 of any year the managing partner may notify the state that it does not intend to renew the agreement; however, in such case the partnership agreement remains in effect for the balance of the existing six year term, and the conservation easement remains in full effect in perpetuity. The conservation easement may be revoked by the landowner only if state funding is terminated without the concurrence of the landowner and cooperating entity. Prior to terminating funding, the State must conduct one or more public hearings. The NAP program is funded through real estate conveyance taxes which are placed in a Natural Area Reserve Fund. Participants in the NAP program must provide annual reports to the Department of Land and Natural Resources (DLNR) and DLNR makes annual inspections of the work in the reserve areas.

                         Haw. Rev. Stat. §§ 195-1-195-11; Hawaii Administrative Rules § 13-210. Management programs within the preserves are documented in long-range management plans and yearly operational plans. These plans detail management measures that protect, restore, and enhance the rare plants and their habitats within the preserves and in adjacent areas (TNCH 1993, 1994a, 1994b, 1997, 1999a, 1999b, 1999c). These management measures address factors which led to the listing of the 23 species including control of non-native species of ungulates, rodents, weeds, and fire. In addition, habitat restoration and monitoring are also included in these plans. Kamakou Preserve The primary management goals within Kamakou Preserve are to (1) prevent degradation of native forest by reducing feral ungulate damage; (2) improve or maintain the integrity of native ecosystems in selected areas of the preserve by reducing the effects of non-native plants; and (3) suppress wildfires. Specific management actions to address feral ungulate impacts include the construction of fences, including strategic fencing (fences placed in proximity to natural barriers such as cliffs); staff hunting; and implementation of organized hunting through the Molokai Hunters Working Group. By monitoring ungulate activity within the preserve, the staff are able to direct hunters to problem areas, thereby increasing hunting success. If increased hunting pressure does not reduce feral ungulate activity in the preserve, the preserve staff will work with the hunting group to identify and implement alternative methods (TNCH 1994, 1999). The non-native plant control program within Kamakou Preserve focuses on habitat modifying non-native plants (weeds) and prioritizes them according to the degree of threat to native ecosystems. A weed priority list has been compiled for the preserve, and control and monitoring of the highest priority species are on-going. Weeds are controlled manually, chemically, or a through a combination of both. Preventative measures (prevention protocol) are required by all (volunteers, riders to the Preserve and hiking participants) who enter the Preserve. This protocol includes such things as brushing footgear before entering the Preserve to remove seeds of non-native plants. In addition, the staff are actively promoting awareness of alien plants in Hawaii and their impacts to native ecosystems in the local communities on Molokai through public education at schools, fairs, and displays at the airport. Wildfire presuppression and response plans are coordinated with the Maui County Fire Department and the DOFAW Maui District Forester. The Kamakou Wildfire Management Plan is reviewed annually with the fire department and updated as necessary (TNCH 1994, 1999). In the event of fires in areas bordering the preserve staff from Kamakou assist with fire suppression in concert with DOFAW staff. Natural resource monitoring and research addresses the need to track the biological and physical resources of the preserve and evaluate changes in these resources to guide management programs. Vegetation is monitored throughout the preserve to document long term ecological changes; rare plant species are monitored to assess population status; and, following fires on the boundaries or within the preserve, burned areas are assessed for ingress of weeds and recovery of native plants. In addition, the preserve staff provide logistical support to scientists and others who are conducting research within the preserve. In addition, TNCH, DOFAW, USFWS and other Federal agencies including the National Park Service, and neighboring landowners of East Molokai's watershed areas have formed a partnership (East Molokai Watershed Partnership) through a memorandum of understanding to ensure the protection of over 22,000 acres on the island. While the partnership is still in its infancy, the members have agreed, in principle, to participate in cooperative management activities within the East Molokai watershed because they believe that effective management is best achieved through the coordinated actions of all major landowners in the watershed. Moomomi Preserve The primary management goals within Moomomi Preserve are to (1) prevent degradation of natural communities by reducing feral ungulate damage; and (2) improve or maintain the integrity of native ecosystems in selected areas of the preserve by reducing the effects of non-native plants (TNCH 1999). Specific management actions to address feral ungulate impacts include the construction of a perimeter fence to keep out livestock and an agreement with the neighboring landowner, Molokai Ranch, in which they will remove livestock within 48 hours of ingress. Analysis of the monitoring data collected within the axis deer exclosure will guide future management strategies (TNCH 1999). As with the Kamakou Preserve, the non-native plant control program within Moomomi Preserve focuses on habitat modifying non-native plants (weeds) and prioritizes them according to the degree of threat to native ecosystems. A weed priority list has been compiled for the preserve, and control and monitoring of the highest priority species are on-going. Weeds are controlled manually, chemically, or a through a combination of both. Preventative measures (prevention protocol) are required by all (volunteers, riders to the Preserve and hiking participants) who enter the Preserve. This protocol includes such things as brushing footgear before entering the Preserve to remove seeds of non-native plants. In addition, the staff are actively promoting awareness of alien plants in Hawaii and their impacts to native ecosystems in the local communities on Molokai through public education at schools, fairs, and displays at the airport (TNCH 1999). Natural resource monitoring and research addresses the need to track the biological and physical resources of the preserve and evaluate changes in these resources to guide management programs. Vegetation is monitored 
                        ( print page 83183)
                        throughout the preserve to document long term ecological changes; rare plant species are monitored to assess population status. In addition, the preserve staff provide logistical support to scientists and others who are conducting research within the preserve (TNCH 1999). Pelekunu Preserve The primary management goals within Pelekunu Preserve are to (1) prevent degradation of native forest by reducing feral ungulate damage; and (2) improve or maintain the integrity of native ecosystems in selected areas of the preserve by reducing the effects of non-native plants. Specific management actions to address feral ungulate impacts include staff hunting; implementation of organized hunting through the Molokai Hunters Working Group; and quarterly transect and aerial monitoring of ungulate activity. By monitoring ungulate activity within the preserve, the staff are able to direct hunters to problem areas, thereby increasing hunting success. If increased hunting pressure does not reduce feral ungulate activity in the preserve, the preserve staff work with the hunting group to identify and implement alternative methods (TNCH 1999). As with the other two preserves on Molokai, the non-native plant control program within Pelekunu Preserve focuses on habitat modifying non-native plants (weeds) and prioritizes them according to the degree of threat to native ecosystems. A weed priority list has been compiled for the preserve, and control and monitoring of the highest priority species are on-going. Weeds are controlled manually, chemically, or a through a combination of both. Preventative measures (prevention protocol) are required by all (volunteers, riders to the Preserve and hiking participants) who enter the Preserve. This protocol includes such things as brushing footgear before entering the Preserve to remove seeds of non-native plants. In addition, the staff are actively promoting awareness of alien plants in Hawaii and their impacts to native ecosystems in the local communities on Molokai through public education at schools, fairs, and displays at the airport. Natural resource monitoring and research addresses the need to track the biological and physical resources of the preserve and evaluate changes in these resources to guide management programs. Vegetation is monitored throughout the preserve to document long term ecological changes; and rare plant species are monitored to assess population status. In addition, the preserve staff provide logistical support to scientists and others who are conducting research within the preserve. Because these plants and their habitats within the preserves receive long-term protection and management these lands are not in need of special management considerations or protection. Therefore, we have determined that the private lands within Moomomi Preserve, Kamakou Preserve, and Pelekunu Preserve do not meet the definition of critical habitat in the Act, and we are not proposing designation of these lands as critical habitat. Should the status of these reserves change, for example by non-renewal of a partnership agreement or termination of NAP funding, we will reconsider whether it then meets the definition of critical habitat. If so, we have the authority to proposed to amend critical habitat to include such area at that time. 50 CFR 424.12(g). Critical habitat is not proposed for six species, 
                        *Adenophorous periens, Hedyotis mannii, Phyllostegia mannii, Plantago princeps, Platanthera holochila,*
                        and 
                        *Schiedea nuttallii,*
                        that are currently only found in Kamakou Preserve and for one species, 
                        *Lysimachia maxima,*
                        that is only found in Pelekunu Preserve. For the 40 species in this proposed rule for which primary constituent elements are known, we believe that Kamakou Preserve, Moomomi Preserve, and Pelekunu Preserve are the only potential critical habitat areas on Molokai at this time that do not require special management considerations or protection. However, we are specifically soliciting comments on the appropriateness of this approach. If we receive information during the public comment period that any of the lands within the proposed designations are actively managed to promote the conservation and recovery of the 40 listed species at issue in this proposed designation, in accordance with long term conservation management plans or agreements, and there are assurances that the proposed management actions will be implemented and effective, the Service can consider this information when making a final determination of critical habitat. In addition, we are aware that other private landowners and the State of Hawaii are considering the development of land management plans or agreements that may promote the conservation and recovery of endangered and threatened plant species on the island of Molokai. The Service supports these efforts and provides technical assistance whenever possible. We are also soliciting comments on whether future development and approval of conservation measures (
                        *e.g.,*
                         Conservation Agreements, Safe Harbor Agreements) should trigger revision of designated critical habitat to exclude such lands and, if so, by what mechanism. In summary, the proposed critical habitat areas described below constitute our best assessment of the physical and biological features needed for the conservation of 32 plant species (

                        *Zanthoxylum hawaiiense*) and the special management needs of the species, and are based on the best scientific and commercial information available and described above. We put forward this proposal 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 to proceed with designation at this time based on the best information available. As new information accrues, we may reevaluate which areas warrant critical habitat designation. We anticipate that comments received through the public review process and from any public hearings, if requested, will provide us with additional information to use in our decision making process and in assessing the potential impacts of designating critical habitat for one or more of these species. The approximate areas of proposed critical habitat, by land ownership, are shown in Table 5. Proposed critical habitat includes habitat for 32 species predominantly on the east side of Molokai. Lands proposed as critical habitat have been divided into 28 units. A brief description of each unit is presented below.

Effects of Critical Habitat Designation Section 7(a) of the Act requires Federal agencies to ensure that actions they fund, authorize, or carry out do not jeopardize the continued existence of a listed species or destroy or adversely modify its critical habitat. Destruction or adverse modification of critical habitat is defined by our regulations 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 (50 CFR 402.02). Individuals, organizations, States, local governments, and other non-Federal entities are affected by the designation of critical habitat only if their actions occur on Federal lands, require a Federal permit, license, or other authorization, or involve Federal funding. Section 7(a) of the Act means that Federal agencies must evaluate their actions with respect to any species that is proposed or listed as endangered or threatened and with respect to its critical habitat, if any is designated or proposed. Regulations implementing this interagency cooperation provision of the Act are codified at 50 CFR Part 402. If a Federal action may affect a listed species or its critical habitat, the responsible Federal agency must enter into consultation with us. If, at the conclusion of consultation, we issue a biological opinion concluding that the project is likely to result in the destruction or adverse modification of critical habitat, we also provide reasonable and prudent alternatives to the project, if any are identifiable. Reasonable and prudent alternatives are defined at 50 CFR 402.02 as alternative actions identified during consultation that can be implemented in a manner consistent with the intended purpose of the action, that are consistent with the scope of the Federal agency's legal authority and jurisdiction, that are economically and technologically feasible, and that the Director believes would avoid destruction or adverse modification of critical habitat. Section 7(a)(4) requires Federal agencies to confer with us on any action that is likely to jeopardize the continued existence of a proposed species or result in destruction or adverse modification of proposed critical habitat. Conference reports provide conservation recommendations to assist the agency in eliminating conflicts that may be caused by the proposed action. The conservation recommendations in a conference report are advisory. We may issue a formal conference report if requested by a Federal agency. Formal conference reports on proposed critical habitat contain biological opinion that is prepared according to 50 CFR 402.12, as if critical habitat were designated. We may adopt the formal conference report as the biological opinion when the critical habitat is designated, if no significant new information or changes in the action alter the content of the opinion. 
                        *See*50 CFR 402.10(d). Regulations at 50 CFR 402.16 require Federal agencies to reinitiate consultation on previously reviewed actions under certain circumstances, including instances where critical habitat is subsequently designated and the Federal agency has retained discretionary involvement or control has been retained or is authorized by law. Consequently, some Federal agencies may request consultation or conferencing with us on actions for which formal consultation has been completed if those actions may affect designated critical habitat or adversely modify or destroy proposed critical habitat. Activities on lands being proposed as critical habitat for these 32 species or activities that may indirectly affect such lands and that conducted by a Federal agency, funded by a Federal agency or require a permit from a Federal agency will be subject to the section 7 consultation process. Federal actions not affecting critical habitat, as well as actions on non-Federal lands that are not federally funded or permitted, will not require Section 7 consultation. Section 4(b)(8) of the Act requires us to briefly describe and evaluate in any proposed or final regulation that designates critical habitat those activities involving a Federal action that may adversely modify such habitat or that may be affected by such designation. Activities that may destroy or adversely modify critical habitat include those that alter the primary constituent elements to the extent that the value of critical habitat for both the survival and recovery of any one of the 32 species is appreciably reduced. We note that such activities may also jeopardize the continued existence of the species. Activities that, when carried out, funded, or authorized by a Federal agency, may directly or indirectly destroy or adversely modify critical habitat include, but are not limited to: (1) Activities that appreciably degrade or destroy habitat defined in the discussion of primary constituent elements including but not limited to: overgrazing; maintenance of feral ungulates; clearing, cutting of native live trees and shrubs, whether by burning or mechanical, chemical, or other means (
                        *e.g.,*
                         woodcutting, bulldozing, construction, road building, mining, herbicide application, etc.); introducing or enabling the spread of non-native species; and taking actions that pose a risk of fire. 
                        ( print page 83187) (2) Water diversion or impoundment, groundwater pumping, or other activity that alters water quality or quantity to an extent that wet forest or bog vegetation is significantly affected; and, (3) Recreational activities that appreciably degrade vegetation. Actions affected by designation of critical habitat may include, but are not limited to: (1) Regulation of activities affecting waters of the United States by the Army Corps of Engineers under section 404 of the Clean Water Act; (2) Development requiring permits from Federal agencies such as Housing and Urban Development; (3) Federally funded silviculture/forestry projects and research by the U.S. Department of Agriculture (Natural Resource Conservation Service and Forest Service); (4) Regulation of airport improvement activities by the Federal Aviation Administration jurisdiction; (5) Road construction and maintenance by, or funded by, the U.S. Department of Transportation; (6) Federally funded importation of alien species for research, agriculture, and aquaculture, and the release or authorization of release of biological control agents by the U.S. Department of Agriculture; (7) Regulation of activities affecting point source pollution discharges into waters of the United States by the Environmental Protection Agency under section 402 of the Clean Water Act; (8) Hazard mitigation and post-disaster repairs funded by the Federal Emergency Management Agency; (9) Installation and maintenance of U.S. Coast Guard navigational aids; (10) Construction of communication sites licensed by the Federal Communications Commission; and (11) Construction activities by the U.S. Department of Interior (National Park Service); (12) Activities not mentioned above funded or authorized by the U.S. Department of Agriculture (Forest Service, Natural Resources Conservation Service), Department of Defense, Department of Transportation, Department of Energy, Department of Interior (U.S. Geological Survey, National Park Service), Department of Commerce (National Oceanic and Atmospheric Administration) or any other Federal agency. If you have questions regarding whether specific activities will constitute adverse modification of critical habitat, contact the Field Supervisor, Pacific Islands Ecological Services Field Office (see 
                        **ADDRESSES**
                         section). Requests for copies of the regulations on listed wildlife and plants and inquiries about prohibitions and permits may be addressed to the U.S. Fish and Wildlife Service, Branch of Endangered Species/Permits. Economic and Other Relevant Impacts Analysis Section 4(b)(2) of the Act requires that we designate critical habitat on the basis of the best scientific and commercial information available and consider the economic and other relevant impacts of designating a particular area as critical habitat. Consideration of economic and other impacts will take place in the final rule. 
                        *See*50 CFR 424.19. Although at this time we cannot identify any incremental effects of this proposed critical habitat designation above those impacts of listing, we will conduct an economic analysis to further evaluate this issue. We will conduct the economic analysis for this proposal prior to a final determination. When the draft economic analysis is completed, we will announce its availablility with a notice in the 
                        **Federal Register**
                        , and we will have a comment period for 30 days at that time to accept comments. We will utilize the final economic analysis, and take into consideration all comments and information regarding economic or other impacts submitted during the public comment period and any public hearings, if requested, to make final critical habitat designations. We may exclude areas from critical habitat upon a determination that the benefits of such exclusions outweigh the benefits of specifying such areas as part of critical habitat; however, we cannot exclude areas from critical habitat when such exclusion will result in the extinction of the species. Public Comments Solicited It is our intent that any final action resulting from this proposal be as accurate and as effective as possible. Therefore, we solicit comments or suggestions from the public, other concerned governmental agencies, the scientific community, industry or any other interested party concerning this proposed rule. In this rule, we do not propose to designate critical habitat on the private lands within Moomomi, Pelekunu, and Kamakou Preserves because these areas are dedicated to conservation and are managed for the benefit of the federally protected plant species found there. We believe that these areas are not in need of special management considerations or protection and, therefore, do not meet the definition of critical habitat in the Act. We are, however, specifically soliciting comments on the appropriateness of this approach. We also invite comments from the public that provide information on whether lands within proposed critical habitat are currently being managed to address conservation needs of these listed plants. As stated earlier in this proposed rule, if we receive information that any of the areas proposed as critical habitat are adequately managed, we may delete such areas from the final rule because they would not meet the definition in section 3(5)(A)(i) of the Act. In determining adequacy of management, we must find that the management effort is sufficiently certain to be implemented and effective so as to contribute to the elimination or adequate reduction of relevant threats to the species. In determining whether an action is likely to be implemented, we will generally consider the following: —Whether or not a management plan or agreement exists which specifies the management actions being implemented, or if to be implemented, the schedule for implementation; —Whether there are responsible party(ies), and funding source(s) or other resources necessary to implement the actions, with a high level of certainty that the funding will be provided; and —The authority and long-term commitment of the party(ies) to the agreement or plan to implement the management action, as demonstrated, for example, by a legal instrument providing enduring protection and management of the lands. In determining whether an action is likely to be effective, we will generally consider whether or not the plan is specific concerning the threats to be addressed by the management actions; whether such actions have been successful in the past; whether there are provisions for monitoring and assessment of the effectiveness of the management actions; and whether adaptive management principles have been incorporated into the plan. We are aware that the State of Hawaii and some private landowners may be considering the development and implementation of land management plans or agreements that may promote the conservation and recovery of endangered and threatened plant species on the island of Molokai. We are soliciting comments in this proposed rule on whether current land management plans or practices applied within the areas proposed as critical habitat adequately address the threats to 
                        ( print page 83188)
                        these listed species. We are also soliciting comments on whether future development and approval of conservation measures (
                        *e.g.,*
                        Conservation Agreements, Safe Harbor Agreements, 
                        *etc.*) should be excluded from critical habitat, and if so, by what mechanism. In addition, we are seeking comments on the following: (1) The reasons why critical habitat for any of these species is prudent or not prudent as provided by section 4 of the Act and 50 CFR 424.12(a)(1), including whether the benefits of designation would outweigh any threats to these species due to designation; (2) The reasons why any particular area should or should not be designated as critical habitat for any of these species, as critical habitat is defined by section 3 of the Act (16 U.S.C. 1532 (5)); (3) Specific information on the amount and distribution of habitat for

                        **ADDRESSES**
                        ). Our practice is to make comments, including names and home addresses of respondents, available for public review during regular business hours. Individual respondents may request that we withhold their home address, which we will honor to the extent allowable by law. There also may be circumstances in which we would withhold a respondent's identity, as allowable by law. If you wish us to withhold your name and/or address, you must state this request prominently at the beginning of your comment. However, we will not consider anonymous comments. To the extent consistent with applicable law, we will make all submissions from organizations or businesses, and from individuals identifying themselves as representatives or officials of organizations or businesses, available for public inspection in their entirety. Comments and materials received will be available for public inspection, by appointment, during normal business hours at the above address. Peer Review In accordance with our policy published on July 1, 1994 (59 FR 34270), we will seek the expert opinions of at least three appropriate and independent specialists regarding this proposed rule. The purpose of such review is to ensure listing and critical habitat decisions are based on scientifically sound data, assumptions, and analyses. We will send copies of this proposed rule to these peer reviewers immediately following publication in the 
                        **Federal Register**
                        . We will invite the peer reviewers to comment, during the public comment period, on the specific assumptions and conclusions regarding the proposed designations of critical habitat. We will consider all comments and data received during the 60-day comment period on this proposed rule during preparation of a final rulemaking. Accordingly, the final decision may differ from this proposal. Clarity of the Rule Executive Order 12866 requires each agency to write regulations and notices that are easy to understand. We invite your comments on how to make this proposed rule easier to understand including answers to questions such as the following: (1) Are the requirements in the proposed rule clearly stated? (2) Does the proposed rule contain technical language or jargon that interferes with the clarity? (3) Does the format of the proposed rule (grouping and order of sections, use of headings, paragraphing, etc.) aid or reduce its clarity? (4) Is the description of the proposed rule in the 
                        **Supplementary Information**
                         section of the preamble helpful in understanding the document? (5) What else could we do to make the proposed rule easier to understand? Send a copy of any comments that concern how we could make this notice easier to understand to: Office of Regulatory Affairs, Department of the Interior, Room 7229, 1849 C Street, NW, Washington, DC 20240. You may e-mail your comments to this address: Execsec@ios.doi.gov. Required Determinations 1. Regulatory Planning and Review In accordance with Executive Order (EO) 12866, this action was submitted for review by the Office of Management and Budget (OMB). We are in the process of preparing an economic analysis to determine the economic consequences of designating the specific areas identified as critical habitat. If our economic analysis reveals that the economic impacts of designating any area as critical habitat outweigh the benefits of designation, we may exclude those areas from consideration, unless such exclusion will result in the extinction of the species. (a) While we will prepare an economic analysis to assist us in considering whether areas should be excluded pursuant to section 4 of the Act, at this time we do not believe this rule will have an annual economic effect of $100 million or adversely affect an economic sector, productivity, jobs, the environment, or other units of government. Therefore we do not believe a cost benefit and economic analysis pursuant to EO 12866 is required. The plants at issue were listed as endangered or threatened species between the years 1991 and 1999. The areas proposed for critical habitat are currently occupied by one or more of these species. Under section 7 of the Act, critical habitat may not be destroyed or adversely modified by a Federal agency action; it does not impose any restrictions on non-Federal persons unless they are conducting activities funded or otherwise sponsored or permitted by a Federal agency (See Table 6). Section 7 also requires Federal agencies to ensure that they do not jeopardize the continued existence of the species. Because of their limited number of individuals and populations, and limited range, we 
                        ( print page 83189)
                        conclude that any Federal action or authorized action that could potentially cause an adverse modification of the proposed critical habitat for any of the 32 species would also likely cause “jeopardy” to that species. Accordingly, the designation of currently occupied areas as critical habitat would not have any additional incremental impacts on what actions may or may not be conducted by Federal agencies or non-Federal persons that receive Federal authorization or funding. Non-Federal persons that do not have a Federal involvement in their actions are not restricted by the designation of critical habitat. (b) This rule will not create inconsistencies with other agencies' actions. As discussed above, Federal agencies have been required to ensure that their actions not jeopardize the continued existence of the 32 plant species since their listing between 1991 and 1999. The prohibition against adverse modification of critical habitat would not be expected to impose any additional restrictions to those that currently exist because all proposed critical habitat is currently occupied. (c) This rule will not materially affect entitlements, grants, user fees, loan programs, or the rights and obligations of their recipients. Federal agencies are currently required to ensure that their activities do not jeopardize the continued existence of the species, and as discussed above we do not anticipate that the adverse modification prohibition resulting from critical habitat designation will have any incremental effects.

 (d) This rule will not raise novel legal or policy issues. The proposed rule follows the requirements for determining critical habitat contained in the Endangered Species Act. 2. Regulatory Flexibility Act (5 U.S.C. 601 
                        *et seq.*) In the economic analysis, we will determine whether designation of critical habitat will have a significant effect on a substantial number of small entities. As discussed under Regulatory Planning and Review above, this rule is not expected to result in any restrictions in addition to those currently in existence. As indicated on Table 5 (see “Methods for Selection of Areas for Proposed Critical Habitat Designations”) we have designated property owned by Federal and State governments, and private property. Within these areas, the types of Federal actions or authorized activities that we have identified as potential concerns are: (1) Regulation of activities affecting waters of the United States by the Army Corps of Engineers under section 404 of the Clean Water Act; (2) Development on private or State lands requiring permits from other Federal agencies such as Housing and Urban Development; (3) Federally funded silviculture/forestry projects and research by the U.S. Department of Agriculture (Natural Resource Conservation Service and Forest Service); (4) Regulation of airport improvement activities by the Federal Aviation Administration jurisdiction; (5) Road construction and maintenance by, or funded by, the U.S. Department of Transportation; (6) Federally funded importation of alien species for research, agriculture, and aquaculture, and the release or authorization of release of biological control agents by the U.S. Department of Agriculture; (7) Regulation of activities affecting point source pollution discharges into waters of the United States by the Environmental Protection Agency under section 402 of the Clean Water Act.; (8) Hazard mitigation and post-disaster repairs funded by the Federal Emergency Management Agency; (9) Installation and maintenance of U.S. Coast Guard navigational aids; (10) Construction of communication sites licensed by the Federal Communications Commission; and (11) Construction activities by the U.S. Department of Interior (National Park Service); (12) Activities not mentioned above funded or authorized by the U.S. Department of Agriculture (Forest Service, Natural Resources Conservation Service), Department of Defense, Department of Transportation, Department of Energy, Department of Interior (U.S. Geological Survey, National Park Service), Department of Commerce (National Oceanic and Atmospheric Administration) or any other Federal agency. Many of these activities authorized or funded by Federal agencies within the proposed critical habitat areas are carried out by small entities (as defined by the Regulatory Flexibility Act) through contract, grant, permit, or other Federal authorization. As discussed in section 1 above, these actions are currently required to comply with the protections of the Act that are triggered by listing, such as avoiding jeopardy to these species, and the designation of critical habitat is not anticipated to have any additional effects on these activities. For actions on non-Federal property that do not have a Federal connection 
                        ( print page 83190)
                        (such as funding or authorization), the current State restrictions concerning take of listed threatened or endangered plant species remain in effect, and this rule would impose no additional restrictions. 3. Small Business Regulatory Enforcement Fairness Act (5 U.S.C. 804(2)) In the economic analysis, we will determine whether designation of critical habitat will cause (a) any effect on the economy of $100 million or more, (b) any increases in costs or prices for consumers, individual industries, Federal, State, or local government agencies, or geographic regions in the economic analysis, or (c) any significant adverse effects on competition, employment, investment, productivity, innovation, or the ability of U.S.-based enterprises to compete with foreign-based enterprises. 4. Unfunded Mandates Reform Act (2 U.S.C. 1501 
                        *et seq.*) In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 1501 
                        *et seq.*): (a) This rule will not “significantly or uniquely” affect small governments. A Small Government Agency Plan is not required. Small governments will only be affected to the extent that any Federal funds, permits or other authorized activities must ensure that their actions will not adversely affect the critical habitat. However, as discussed in section 1, these actions are currently subject to equivalent restrictions through the listing protections of the species, and no further restrictions are anticipated. (b) This rule will not produce a Federal mandate of $100 million or greater in any year, that is, it is not a “significant regulatory action” under the Unfunded Mandates Reform Act. The designation of critical habitat imposes no obligations on State or local governments. 5. Takings In accordance with Executive Order 12630, this rule does not have significant takings implications. A takings implication assessment is not required. As discussed above, the designation of critical habitat affects only Federal agency actions. The rule will not increase or decrease the current restrictions on private property concerning take of the 32 plant species. We do not anticipate that property values will be affected by the critical habitat designations. Landowners in areas that are included in the designated critical habitat will continue to have opportunity to utilize their property in ways consistent with State law and with the continued survival of the plant species. 6. Federalism In accordance with Executive Order 13132, the rule does not have significant Federalism effects. A Federalism assessment is not required. As discussed above, the designation of critical habitat in areas currently occupied by the 32 plant species would have little incremental impact on State and local governments and their activities. The designations may have some benefit to these governments in that the areas essential to the conservation of these species are more clearly defined, and the primary constituent elements of the habitat necessary to the survival of the species are identified. While this definition and identification does not alter where and what federally sponsored activities may occur, it may assist these local governments in long range planning rather than waiting for case-by-case section 7 consultation to occur. 7. Civil Justice Reform In accordance with Executive Order 12988, the Office of the Solicitor has determined that the rule does not unduly burden the judicial system and meets the requirements of sections 3(a) and 3(b)(2) of the Order. We designate critical habitat in accordance with the provisions of the Endangered Species Act. The rule uses standard property descriptions and identifies the primary constituent elements within the designated areas to assist the public in understanding the habitat needs of the 32 plant species. 8. Paperwork Reduction Act of 1995 (44 U.S.C. 3501 
                        *et seq.*) This rule does not contain any information collection requirements for which OMB approval under the Paperwork Reduction Act is required. 9. National Environmental Policy Act We have determined that an Environmental Assessment and/or an Environmental Impact Statement as defined by the National Environmental Policy Act of 1969 need not be prepared in connection with regulations adopted pursuant to section 4(a) of the Act, as amended. A notice outlining our reason for this determination was published in the 
                        **Federal Register**
                         on October 25, 1983 (48 FR 49244). This proposed rule does not constitute a major Federal action significantly affecting the quality of the human environment. 10. Government-to-Government Relationship With Tribes In accordance with the President's memorandum of April 29, 1994, “Government-to-Government Relations with Native American Tribal Governments” (59 FR 22951) and 512 DM 2, we understand that Federally recognized Tribes must be related to on a Government-to-Government basis. The 1997 Secretarial Order on Native Americans and the Act clearly states that Tribal lands should not be designated unless absolutely necessary for the conservation of the species. According to the Secretarial Order, “Critical habitat shall not be designated in an area that may impact Tribal trust resources unless it is determined essential to conserve a listed species. In designating critical habitat, the Services shall evaluate and document the extent to which the conservation needs of a listed species can be achieved by limiting the designation to other lands.” We determined that no Tribal lands are essential for any of the 18 plantsspecies for which critical habitat designation is proposed because none of these plants are known to occur on Tribal lands.

 § 17.96
  (a) * * * (1) * * * (i) 
                                *Maps and critical habitat unit descriptions.*
                                 The following sections contain the legal descriptions of the critical habitat units designated for each of the Hawaiian islands. Existing features and structures within proposed areas, such as buildings, roads, aquaducts, telecommunication equipment, arboreta and gardens, heiaus (indigenous place of worship, shrine) and other man-made features do not contain, and are not likely to develop, the constituent elements described for each species in paragraphs (a)(1)(ii)(A) and (a)(1)(ii)(B) of this section. Therefore, these features or structures are not included in the critical habitat designation.
