    SUMMARY: The U.S. Fish and Wildlife Service (Service) proposes 
    endangered species status pursuant to the Endangered Species Act of 
    1973, as amended (Act), for the plant Delissea undulata (No Common 
    Name). This species is known only from one individual, located on the 
    island of Hawaii. The greatest immediate threats to the survival of 
    this species are habitat degradation and predation by domestic and 
    feral mammals, fire, and competition with alien plants. The small 
    population size of one individual with its limited gene pool also 
    comprises a serious threat to this species. This proposal, if made 
    final, would implement the Federal protection and recovery provisions 
    provided by the Act.
    
    DATES: Comments from all interested parties must be received by August 
    26, 1994. Public hearing requests must be received by August 11, 1994.
    
    ADDRESSES: Comments and materials concerning this proposal should be

    SUPPLEMENTARY INFORMATION:
    
    Background
    
        Delissea undulata was first described by Charles Gaudichaud-Beaupre 
    from specimens he collected in the Hawaiian Islands (``Isles 
    Sandwich'') in 1819 (St. John 1959). He chose the specific epithet to 
    refer to the undulating margins of the leaves. F.E. Wimmer named a 
    specimen J.F. Rock collected in 1911 from Kanahaha, Kona, as Cyanea 
    arqutidenta, which H. St. John later moved to the genus Delissea (St. 
    John 1959, Wimmer 1943). St. John also named a specimen collected in 
    1968 from the southern Kona District as D. konaensis (St. John 1986). 
    The current treatment of the family (Lammers 1988, 1990) considers all 
    of the above species to be synonymous with D. undulata. Lammers 
    recognizes three subspecies of D. undulata: subsp. niihauensis, subsp. 
    kauaiensis, and subsp. undulata (Lammers 1988, 1990).
        Delissea undulata of the bellflower family (Campanulaceae) is a 
    palm-like tree with unbranched woody stems 2 to 10 meters (m) (6 to 30 
    feet (ft)) tall. The leaves are long and narrow or elliptic with long 
    petioles and undulate or flat, toothed margins, about 5 to 21 
    centimeters (cm) (2 to 8 inches (in)) long and 3 to 10 cm (1 to 4 in) 
    wide. The flowering stalk bears 5 to 20 greenish-white, slightly down-
    curved flowers 1.6 to 2.5 cm (0.6 to 1.0 in) long with one or two small 
    knobs on the upper surfaces. The fruits are ovoid to globose purple 
    berries 0.6 to 1.2 cm (0.2 to 0.4 in) long. The three subspecies of D. 
    undulata can be distinguished from each other by leaf shape and leaf 
    margin characteristics: subsp. kauaiensis has ovate leaves with flat, 
    sharply toothed margins; subsp. niihauensis has leaves with heart-
    shaped bases and shallow roundly toothed margins; and subsp. undulata 
    has narrower, lance-shaped leaves with undulating margins and 
    spreading, pointed teeth (Lammers 1988, 1990). The species D. undulata 
    is distinguished from closely related species in this genus by its 
    broader leaf bases, larger flowers, and larger berries (Lammers 1990).
        Historically, D. undulata is known from Niihau, Kauai, Maui, and 
    Hawaii. Subspecies kauaiensis was collected west of the Hanapepe River 
    on the island of Kauai by A.A. Heller in 1895 and has not been 
    relocated (Hawaii Heritage Program (HHP) 1991a, Heller 1897, Lammers 
    1988). Subspecies niihauensis was collected twice in the 1800's on the 
    island of Niihau and has not been located since (HHP 1991b, Hillebrand 
    1888, St. John 1959). Both of these subspecies are considered extinct 
    (HHP 1991a, 1991b; Lammers 1990). Delissea undulata subsp. undulata was 
    reported from four valleys of southwestern Maui in the 1800's, and from 
    the Kona region of the island of Hawaii (HHP 1991c1 to 1991c9). This 
    subspecies was observed in 1971 at Puu Lehua and was subsequently 
    thought to be extinct (HHP 1991c6, Lammers 1990). However, one 
    individual plant was discovered on April 24, 1992, at Puu Waawaa, at a 
    previously unreported location on Hualalai on the island of Hawaii (Jon 
    Giffin, Hawaii Department of Land and Natural Resources (Hawaii DLNR), 
    in litt. 1993).
        Delissea undulata grows primarily in dry and mesic forests at about 
    1,000 to 1,750 m (3,300 to 5,700 ft) elevation (Lammers 1990; J. 
    Giffin, in litt., 1993). The substrate is a thin organic soil layer 
    over 'a'a or pahoehoe lava (Department of Geography 1983). The only 
    known individual grows on the brink of a collapsed lava tube at 1070 m 
    (3520 ft) elevation. The vegetation is open Sophora chrysophylla 
    (mamane)-Metrosideros polymorpha ('ohia) forest with such associated 
    species as Santalum ellipticum ('iliahi) and Acacia koa (koa). The 
    endangered species Nothocestrum breviflorum ('aiea) also is found in 
    the area of the one remaining individual of D. undulata. Introduced 
    plants in the area include Pennisetum clandestinum (kikuyu grass), 
    Passiflora mollissima (banana poka), and Senecio mikanioides (German 
    ivy) (J. Giffin, in litt., 1993).
        The greatest immediate threats to the survival of D. undulata are 
    damage from domestic and feral herbivores and competition with alien 
    plants. Fire, whether started naturally or by arson, poses a serious 
    threat to the population. The small population size of one individual 
    with its limited gene pool also comprises a serious threat to this 
    species (J. Giffin, in litt., 1993).
    
    Previous Federal Action
    
        Federal action on this species began as a result of section 12 of 
    the Endangered Species Act (16 U.S.C. 1531 et seq.), which directed the 
    Secretary of the Smithsonian Institution to prepare a report on plants 
    considered to be endangered, threatened, or extinct. This report, 
    designated as House Document No. 94-51, was presented to Congress on 
    January 9, 1975. On July 1, 1975, the Service published a notice in the 
    Federal Register (40 FR 27823) accepting the report as a petition 
    within the context of section 4(c)(2) (now section 4(b)(3)(A)) of the 
    Act, and giving notice of its intention to review the status of the 
    plant taxa named therein. In this and subsequent notices, D. undulata 
    var. undulata was included as extinct, and D. undulata var. argutidenta 
    was included as endangered. As a result of this review, on June 16, 
    1976, the Service published a proposed rule in the Federal Register (41 
    FR 24523) to determine approximately 1,700 vascular plant species, 
    including D. undulata, endangered pursuant to section 4 of the Act. In 
    1978, amendments to the Act required that all proposals over 2 years 
    old be withdrawn. A 1-year grace period was given to proposals already 
    over 2 years old. On December 10, 1979, the Service published a notice 
    in the Federal Register (44 FR 70796) of the withdrawal of that portion 
    of the June 16, 1976, proposal that had not been made final, along with 
    four other proposals that had expired.
        The Service published an updated Notice of Review for plants on 
    December 15, 1980 (45 FR 82480), including D. undulata as a category 1 
    candidate, meaning that the Service had substantial information 
    indicating that a listing proposal was appropriate. In the updated 
    Notice of Review for plants on September 27, 1985 (50 FR 39525), and 
    February 21, 1990 (55 FR 6183), D. undulata was included as a Category 
    1* candidate, meaning that the Service had substantial information 
    indicating that this taxon was vulnerable in the recent past but may 
    already have become extinct. Section 4(b)(3)(B) of the 1982 amendments 
    to the Act, requires the Secretary to make findings on certain pending 
    petitions within 12 months of their receipt. Section 2(b)(1) of the 
    1982 amendments further requires that all petitions pending on October 
    13, 1982, be treated as having been newly submitted on that date. The 
    latter was the case for D. undulata because the Service had accepted 
    the 1975 Smithsonian report as a petition. On October 13, 1983, the 
    Service found that the listing of the species was warranted but 
    precluded by other pending listing actions, in accordance with section 
    4(b)(3)(B)(iii) of the Act. Notification of this finding was published 
    on January 20, 1984 (49 FR 2485). Such a finding requires the petition 
    to be recycled, pursuant to section 4(b)(3)(C)(i) of the Act. The 
    finding was reviewed in October of 1984, 1985, 1986, 1987, 1988, 1989, 
    1990, 1991, and 1992. Publication of the present proposal constitutes 
    the final 1-year finding.
    
    Summary of Factors Affecting the Species
    
        Section 4 of the Act and regulations (50 CFR part 424) promulgated 
    to implement the listing provisions of the Act set forth the procedures 
    for adding species to the Federal lists. A species may be determined to 
    be an endangered or threatened species due to one or more of the five 
    factors described in section 4(a)(1). These factors and their 
    application to Delissea undulata Gaud. (No Common Name) are as follows:
    
    A. The Present or Threatened Destruction, Modification, or Curtailment 
    of Its Habitat or Range
    
        The habitat of Delissea undulata has undergone extreme alteration 
    because of past and present land management practices, including 
    deliberate and accidental alien mammal and plant introductions and 
    agricultural development. Natural disturbances such as the collapse of 
    lava tubes also destroy habitat and can have a significant effect on 
    small populations of plants. Competition with alien plants as well as 
    destruction of individuals and modification of habitat by introduced 
    animals are the primary threats facing this species.
        Beginning with Captain James Cook in 1792, early European explorers 
    introduced livestock, which became feral, increased in number and 
    range, and caused significant changes to the natural environment of 
    Hawaii. The 1848 provision for land sales to individuals allowed large-
    scale agricultural and ranching ventures to begin. Land was cleared for 
    these enterprises to such a great extent that climatic conditions began 
    to change and the amount and distribution of rainfall were altered 
    (Wenkam 1969).
        Past and present impacts of introduced alien animals are the 
    primary factor in altering and degrading vegetation and habitats on the 
    island of Hawaii as well as on Kauai and Maui, where populations of D. 
    undulata previously existed. Feral ungulates trample and eat native 
    vegetation and disturb open areas. This causes erosion and allows the 
    invasion of alien plant species (Cuddihy and Stone, 1990, Wagner et al. 
    1990). Delissea undulata is threatened by habitat degradation resulting 
    from introduced ungulates (e.g., cattle, goats, sheep, and pigs). 
    Habitat degradation by these ungulates threatens the only known 
    individual plant, any potential natural germination of seedlings, as 
    well as potential suitable habitat occurring throughout the historic 
    range of the species.
        Cattle (Bos taurus), native to Europe, northern Africa, and 
    southwestern Asia, were introduced to the Hawaiian Islands in 1793. 
    Large feral herds developed as a result of restrictions on killing 
    cattle decreed by King Kamehameha I. Large ranches in the tens of 
    thousands of acres were created on Maui and Hawaii. Much of the land 
    used in these private enterprises was leased from the State or was 
    privately owned. Feral cattle formerly existed on Maui and damaged the 
    forests there. Feral cattle are presently found on the island of 
    Hawaii, and ranching is still a major commercial activity there. Cattle 
    eat native vegetation, trample roots and seedlings, cause erosion, 
    create disturbed areas into which alien plants invade, and spread seeds 
    of alien plants in their feces and on their bodies. The forest becomes 
    degraded to grassland pasture in areas grazed by cattle, and plant 
    cover is reduced for many years following removal of cattle from an 
    area. Several alien grasses and legumes purposely introduced for cattle 
    forage have become noxious weeds (Cuddihy and Stone 1990, Tomich 1986). 
    Cattle have altered and degraded the vegetation of much of Hawaii, 
    including the areas where D. undulata may have formerly grown, and 
    where it is still known to exist (Tomich 1986; J. Giffin, in litt., 
    1993). Hunting of feral cattle is no longer allowed in Hawaii (Hawaii 
    DLNR 1985).
        Goats (Capra hircus), native to the Middle East and India, were 
    successfully introduced to the Hawaiian Islands in 1792, and currently 
    there are populations on Kauai, Oahu, Molokai, Maui, and Hawaii. On 
    Kauai, feral goats have been present in drier, more rugged areas since 
    1820; they still occur in Waimea Canyon. On Hawaii, goats damage low 
    elevation dry forest, montane parkland, subalpine woodlands, and alpine 
    grasslands. Goats are managed in Hawaii as a game animal, but many 
    herds populate inaccessible areas where hunting has little effect on 
    their numbers. Goat hunting is allowed year-round or during certain 
    months, depending on the area (Hawaii DLNR n.d., 1985). Goats browse on 
    introduced grasses and native plants, especially in drier and more open 
    ecosystems. They also trample roots and seedlings, cause erosion, and 
    promote the invasion of alien plants. They are able to forage in 
    extremely rugged terrain and have a high reproductive capacity (Cuddihy 
    and Stone 1990, Culliney 1988, Tomich 1986). Delissea undulata 
    currently is threatened by goats that use the area where the single 
    known individual exists (J. Giffin, in litt., 1993).
        Sheep (Ovis aries) became firmly established on the island of 
    Hawaii (Tomich 1986) following their introduction almost 200 years ago 
    (Cuddihy and Stone 1990). Like feral goats, sheep roam the upper 
    elevation dry forests, including Puu Waawaa, causing damage similar to 
    that of goats (Stone 1985). Sheep have decimated vast areas of native 
    forest and shrubland on Hawaii. Sheep threaten the habitat of D. 
    undulata (Cuddihy and Stone 1990; J. Giffin, in litt., 1993) as well as 
    individual plants.
        Pigs (Sus scrofa) are originally native to Europe, northern Africa, 
    Asia Minor, and Asia. European pigs, introduced to Hawaii by Captain 
    James Cook in 1778, became feral and invaded forested areas, especially 
    wet and mesic forests and dry areas at high elevations. They currently 
    are present on Kauai, Oahu, Molokai, Maui, and Hawaii and inhabit rain 
    forests and grasslands. Pig hunting is allowed on all islands either 
    year-round or during certain months, depending on the area (Hawaii DLNR 
    n.d., 1985). While rooting in the ground in search of the invertebrates 
    and plant material they eat, feral pigs disturb and destroy vegetative 
    cover, trample plants and seedlings, and threaten forest regeneration 
    by damaging seeds and seedlings. They disturb soil substrates and cause 
    erosion, especially on slopes. Alien plant seeds are dispersed in their 
    hooves and coats as well as through their digestive tracts, and the 
    disturbed soil is fertilized by their feces, helping these plants to 
    establish (Cuddihy and Stone 1990, Smith 1985, Stone 1985, Tomich 1986, 
    Wagner et al. 1990). Feral pigs pose a threat to D. undulata and its 
    habitat (J. Giffin, in litt., 1993).
    
    B. Overutilization For Commercial, Recreational, Scientific, or 
    Educational Purposes
    
        Unrestricted collecting for scientific or horticultural purposes 
    and excessive visits by individuals interested in seeing rare plants 
    could result from increased publicity. This is a potential threat to 
    Delissea undulata, which is represented by only one known individual. 
    The species is of some horticultural and ornamental interest. Taking 
    and vandalism are potential threats that could result from increased 
    specific publicity.
    
    C. Disease or Predation
    
        Cattle, goats, pigs, and sheep have been reported in the area where 
    Delissea undulata is known to occur. As this taxon is not known to be 
    unpalatable to these ungulates, predation is a probable threat where 
    these animals have been reported. The lack of seedlings and the 
    occurrence of the only known individual in an area less accessible to 
    ungulates seem to indicate the effect that browsing mammals, especially 
    cattle, have had in restricting the distribution of this plant. Though 
    not legally obligated to protect the species, the State fenced the one 
    individual to protect it from further damage by ungulates (J. Giffin, 
    in litt., 1993). See Factor D.
        Of the four species of rodents which have been introduced to the 
    Hawaiian Islands, the species with the greatest impact on the native 
    flora and fauna is probably the roof or black rat (Rattus rattus), 
    which now occurs on all the main Hawaiian Islands around human 
    habitations, in cultivated fields, and in dry to wet forests. Roof 
    rats, and to a lesser extent house mouse (Mus musculus), Polynesian rat 
    (R. exulans), and Norway rat (R. norvegicus) eat the fruits of some 
    native plants, especially those with large, fleshy fruits. Many native 
    Hawaiian plants produce their fruit over an extended period of time, 
    and this produces a prolonged food supply which supports rodent 
    populations. It is probable that rats damage the fleshy fruit of D. 
    undulata. Introduced game birds also may eat the fruits (J. Giffin, in 
    litt., 1993).
    
    D. The Inadequacy of Existing Regulatory Mechanisms
    
        The only known population of Delissea undulata occurs on State 
    land. The species is not presently listed as an endangered species by 
    the State of Hawaii. Therefore no State regulatory protection is in 
    effect for this species. State laws relating to the conservation of 
    biological resources allow for the acquisition of land as well as the 
    development and implementation of programs concerning the conservation 
    of biological resources (HRS, sect. 195D-5(a)). Hawaii's Endangered 
    Species Act states, ``Any species of aquatic life, wildlife, or land 
    plant that has been determined to be an endangered species pursuant to 
    the [Federal] Endangered Species Act shall be deemed to be an 
    endangered species under the provisions of this chapter . . .'' (HRS, 
    sect. 195D-4(a)). Federal listing would automatically invoke listing 
    under Hawaii State law, which prohibits taking of endangered plants in 
    the State and encourages conservation by State agencies (HRS, sect. 
    195D-4). The State also may enter into agreements with Federal agencies 
    to administer and manage any area required for the conservation, 
    management, enhancement, or protection of endangered species (HRS, 
    sect. 195D-5(c)). If listing were to occur, funds for these activities 
    could be made available under section 6 of the Federal Act (State 
    Cooperative Agreements).
        Conservation district lands (HRS, sect. 205-4) are regarded, among 
    other purposes, as necessary for the protection of endemic biological 
    resources and the maintenance or enhancement of the conservation of 
    natural resources. Requests for amendments to district boundaries or 
    variances within existing classifications can be made by government 
    agencies and private landowners (HRS, sect. 205-4). The Hawaii 
    Department of Land and Natural Resources is mandated to initiate 
    changes in conservation district boundaries to include ``the habitat of 
    rare native species of flora and fauna within the conservation 
    district'' (HRS, sect. 195D-5.1). Hawaii environmental policy, and thus 
    approval of land use, is required by law to safeguard ``. . . the 
    State's unique natural environmental characteristics . . .'' (HRS, 
    sect. 344-3(1)) and includes guidelines to ``protect endangered species 
    of individual plants and animals . . .'' (HRS, sect. 344-4(3)(A)). 
    Federal listing, because it automatically invokes State listing, would 
    also trigger these other State regulations protecting D. undulata. 
    Federal listing as endangered would offer additional protection to this 
    species since it would be a violation of the Act for any person to 
    remove, cut, dig up, damage, or destroy any such plant in an area not 
    under Federal jurisdiction in knowing violation of State law or 
    regulation or in the course of any violation of a State criminal 
    trespass law.
    
    E. Other Natural Or Manmade Factors Affecting Its Continued Existence
    
        The fact that there is only one remaining individual of Delissea 
    undulata increases the potential for extinction from stochastic events. 
    The limited gene pool may depress reproductive vigor, or a single 
    human-caused or natural environmental disturbance could destroy the 
    only known extant individual. This constitutes a major threat to D. 
    undulata.
        Natural changes to habitat and substrate can result in the death of 
    individual plants as well as the destruction of their habitat. This 
    especially affects the continued existence of taxa or populations with 
    limited numbers and/or narrow ranges and is often exacerbated by human 
    disturbance and land use practices (See Factor A). Additional collapse 
    of the lava tube where the only known individual of D. undulata occurs 
    is a potential threat to this species (J. Giffin, in litt., 1993).
        Three species of introduced plants threaten D. undulata. The 
    historic native flora of Hawaii consisted of about 1,000 species, 89 
    percent of which were endemic. Of the total native and naturalized 
    Hawaiian flora of 1,817 species, 47 percent were introduced from other 
    parts of the world and nearly 100 species have become pests (Smith 
    1985, Wagner et al. 1990). Naturalized, introduced species degrade the 
    Hawaiian landscape and compete with native plants for space, light, 
    water, and nutrients (Cuddihy and Stone 1990). Some of these species 
    were brought to Hawaii by various groups of people, including the 
    Polynesian immigrants, for food or cultural reasons. Plantation owners, 
    alarmed at the reduction of water resources for their crops caused by 
    the destruction of native forest cover by grazing feral animals, 
    supported the introduction of alien tree species for reforestation. 
    Ranchers intentionally introduced pasture grasses and other species for 
    agriculture, and sometimes inadvertently introduced weed seeds as well. 
    Other plants were brought to Hawaii for their potential horticultural 
    value (Cuddihy and Stone 1990, Wenkam 1969).
        Passiflora mollissima (banana poka), a woody vine, poses a serious 
    problem to mesic forests on Kauai and Hawaii by covering trees, 
    reducing the amount of light that reaches trees as well as understory, 
    and causing damage and death to trees by the weight of the vines. 
    Animals, especially feral pigs, eat the fruit and distribute the seeds 
    (Cuddihy and Stone 1990, Escobar 1990). P. mollissima is a threat to D. 
    undulata and its habitat (J. Giffin, in litt., 1993.
        Senecio mikanioides (German ivy) is another vine that poses a 
    serious threat to mesic and dry forests on Hawaii. It is becoming 
    established on Maui as well. Senecio mikanioides may be capable of 
    establishing itself over vast areas of the island of Hawaii, including 
    most of Hualalai. The vine covers the forest canopy, which can result 
    in structural damage and the reduction of available light. Senecio 
    mikanioides also can form a significant ground cover in native forests 
    of the southern Kona region of Hawaii where it may limit native plant 
    reproduction (Cuddihy and Stone 1990). Senecio mikanioides threatens D. 
    undulata and its habitat (J. Giffin, in litt., 1993).
        Pennisetum clandestinum (Kikuyu grass), an aggressive, fire 
    adapted, perennial grass introduced to Hawaii as a pasture grass, 
    withstands trampling and grazing and has naturalized on four Hawaiian 
    Islands in dry to mesic forest. It produces thick mats which choke out 
    other plants and prevent their seedlings from becoming established. It 
    has been declared a noxious weed by the U.S. Department of Agriculture 
    (7 CFR 360) (O'Connor 1990, Smith 1985). Because Hawaiian plants were 
    subjected to fire during their evolution only in areas of volcanic 
    activity and from occasional lightning strikes, they are not adapted to 
    recurring fire regimes and are unable to recover well following a fire. 
    Fires may result from natural causes, or they may be accidentally or 
    purposely set by people. Vegetation on the slopes of Hualalai is 
    particularly vulnerable to fire due to the extensive invasion of P. 
    clandestinum. Alien plants are often better adapted to fire than native 
    plant species, and some fire-adapted grasses have become widespread in 
    Hawaii. Native shrubland can thus be converted to land dominated by 
    alien grasses. The presence of such species in Hawaiian ecosystems 
    greatly increases the intensity, extent, and frequency of fire, 
    especially during drier months or drought. Fire-adapted alien species 
    can reestablish in a burned area, resulting in a reduction in the 
    amount of native vegetation after each fire. Fire can destroy dormant 
    seeds as well as mature plants and seedlings, even in steep or 
    inaccessible areas. The only known individual of D. undulata occurs in 
    an area heavily grazed by cattle, and is offered some protection from 
    fires since the cattle reduce the fuel load of P. clandestinum. 
    However, fire remains a potentially serious threat to the only known 
    individual of D. undulata, its potential regeneration, and other 
    suitable habitat (J. Giffin, in litt., 1993).
        The Service has carefully assessed the best scientific and 
    commercial information available regarding the past, present, and 
    future threats faced by D. undulata in determining to propose this 
    rule. Based on this evaluation, the preferred action is to list D. 
    undulata as endangered. Only one individual of this species is known to 
    exist, and it is threatened by habitat degradation by feral ungulates 
    and alien plants, fire, and lack of legal protection. Small population 
    size makes this species particularly vulnerable to reduced reproductive 
    vigor and/or extinction from stochastic events. Because this species is 
    in danger of extinction throughout all of its range, it fits the 
    definition of endangered as defined in the Act.
    
    Critical Habitat
    
        Section 4(a)(3) of the Act, as amended, requires that to the 
    maximum extent prudent and determinable, the Secretary designate 
    critical habitat at the time a species is listed as endangered or 
    threatened. The Service finds that designation of critical habitat is 
    not presently prudent for this species. Such a determination would 
    result in no known benefit to Delissea undulata. The extant population 
    is on State land; State government agencies can be alerted to the 
    presence of the plant without the publication of critical habitat 
    descriptions and maps. The publication of such descriptions and maps 
    would potentially increase the degree of threats from taking or 
    vandalism because a live specimen of D. undulata  would be of interest 
    to curiosity seekers or collectors of rare plants. Taking prohibitions 
    are difficult to enforce, and publication of critical habitat 
    descriptions and maps would make D. undulata more vulnerable to taking 
    and increase enforcement problems. All involved parties and landowners 
    have been notified of the importance of protecting this species' 
    habitat. Protection of the species' habitat will be addressed through 
    the recovery process. There are no known Federal activities within the 
    currently known habitat of this species. Therefore, the Service finds 
    that designation of critical habitat for this species is not prudent at 
    this time, because such designation would increase the degree of threat 
    from vandalism, collecting, or other human activities and because it is 
    unlikely to aid in the conservation of this species.
    
    Available Conservation Measures
    
        Conservation measures provided to species listed as endangered or 
    threatened under the Endangered Species Act include recognition, 
    recovery actions, requirements for Federal protection, and prohibitions 
    against certain activities. Recognition through listing results in 
    public awareness and conservation actions by Federal, State, and local 
    agencies, private organizations, and individuals. Harold L. Lyon 
    Arboretum of the University of Hawaii at Manoa is propagating seeds 
    collected from the one remaining individual as part of an ex situ 
    conservation program. The Arboretum has over 300 seedlings growing as 
    part of this conservation program, and has sent approximately 20 
    individuals to the State's Hawaii forestry district for experimental 
    outplanting in the Puu Waawaa area (Charles H. Lamoureux, Harold L. 
    Lyon Arboretum at University of Hawaii and J. Giffin, pers. comms.). 
    The Act provides for possible land acquisition and cooperation with the 
    State and requires that recovery actions be carried out for all listed 
    species. Since Delissea undulata is known to occur on State land, 
    cooperation between Federal and State agencies is necessary to provide 
    for its conservation. The protection required of Federal agencies and 
    the prohibitions against certain activities involving listed plants are 
    discussed, in part, below.
        Section 7 of the Act, as amended, requires Federal agencies to 
    evaluate their actions with respect to any species that is proposed or 
    listed as endangered or threatened and with respect to its critical 
    habitat, if any is being designated. Regulations implementing this 
    interagency cooperation provision of the Act are codified at 50 CFR 
    part 402. Section 7(a)(4) of the Act requires Federal agencies to 
    confer informally with the Service 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. If a 
    species is listed subsequently, section 7(a)(2) requires Federal 
    agencies to insure that activities they authorize, fund, or carry out 
    are not likely to jeopardize the continued existence of such a species 
    or to destroy or adversely modify its critical habitat. If a Federal 
    action may affect a listed species or its critical habitat, the 
    responsible Federal agency must enter into formal consultation with the 
    Service. No Federal involvement is known or anticipated that would 
    affect D. undulata, as the only known site is on State owned land.
        The Act and its implementing regulations set forth a series of 
    general prohibitions and exceptions that apply to all endangered 
    plants. All prohibitions of section 9(a)(2) of the Act, implemented by 
    50 CFR 17.61, would apply to D. undulata. These prohibitions, in part, 
    make it illegal for any person subject to the jurisdiction of the 
    United States to import or export, transport in interstate or foreign 
    commerce in the course of a commercial activity, sell or offer for sale 
    in interstate or foreign commerce, remove and reduce to possession an 
    endangered plant species from areas under Federal jurisdiction, 
    maliciously damage or destroy any such species on any area under 
    Federal jurisdiction, or remove, cut, dig up, damage, or destroy any 
    such species on any other area in knowing violation of any State law or 
    regulation or in the course of any violation of a State criminal 
    trespass law. Certain exceptions apply to agents of the Service and 
    State conservation agencies. The Act and 50 CFR 17.62 and 17.63 also 
    provide for the issuance of permits to carry out otherwise prohibited 
    activities involving endangered plants under certain circumstances. 
    Such permits are available for scientific purposes and to enhance the 
    propagation and survival of the species. It is anticipated that few 
    trade permits would ever be sought or issued because the species is 
    uncommon in cultivation and is very rare in the wild.
        Requests for copies of the regulations regarding listed plants and 
    inquiries regarding prohibitions and permits may be addressed to the 
    U.S. Fish and Wildlife Service, Ecological Services, Endangered Species 
    Permits, 911 NE 11th Avenue, Portland, Oregon 97232-4181 (503) 231-6131

    Public Comments Solicited
    
        The Service intends that any final action resulting from this 
    proposal will be as accurate and as effective as possible. Therefore, 
    comments or suggestions from the public, other concerned governmental 
    agencies, the scientific community, industry, or any other interested 
    party concerning this proposed rule are hereby solicited. Comments 
    particularly are sought concerning:
        (1) biological, commercial trade, or other relevant data concerning 
    any threat (or lack thereof) to this species;
        (2) the location of any additional populations of this species and 
    the reasons why any habitat should or should not be determined to be 
    critical habitat as provided by section 4 of the Act;
        (3) additional information concerning the range, distribution, and 
    population size of this species; and
        (4) current or planned activities in the subject area and their 
    possible impacts on this species.
        The final decision on this proposal will take into consideration 
    the comments and any additional information received by the Service, 
    and such communications may lead to a final regulation that differs 
    from this proposal.
        The Endangered Species Act provides for a public hearing on this 
    proposal, if requested. Requests must be received within 45 days of the 
    date of publication of the proposal. Such requests must be made in 
    writing and addressed to the Pacific Islands Field Supervisor (see 
    ADDRESSES section).
    
    National Environmental Policy Act
    
        The Fish and Wildlife Service has determined that an Environmental 
    Assessment, as defined under the authority of the National 
    Environmental Policy Act of 1969, need not be prepared in connection 
    with regulations adopted pursuant to section 4(a) of the Endangered 
    Species Act of 1973, as amended. A notice outlining the Service's 
    reasons for this determination was published in the Federal Register on 
    October 25, 1983 (48 FR 49244).
