    species status pursuant to the Endangered Species Act of 1973, as 
    amended (Act) for the plant Plagiobothrys hirtus (rough popcornflower). 
    This species is restricted to wet swales and meadows in Douglas County, 
    Oregon, where only 10 occurrences are known. Most populations are small 
    with few individuals. The total estimated number of plants is 3,000 
    within a combined area of about 4 hectares (ha) (10 acres (ac)). 
    Threats to this species include destruction and/or alteration of 
    habitat by development and hydrological changes (e.g., wetland fills, 
    draining, construction); spring and summer grazing by domestic cattle, 
    horses, and sheep; roadside maintenance; and competition from native 
    and alien plant species. This proposal, if made final, would implement 
    the Federal protection and recovery programs of the Act for this plant.
    
    DATES: Comments from all interested parties must be received by January 
    20, 1998. Public hearing requests must be received by January 5, 1998.
    
    ADDRESSES: Comments and materials concerning this proposal should be 
    sent to the State Supervisor, U.S. Fish and Wildlife Service, Oregon 
    State Office, 2600 S.E. 98th Ave., Suite 100, Portland, Oregon 97266. 
    Comments and materials received will be available for public inspection 
    by appointment during normal business hours at the above address.

    SUPPLEMENTARY INFORMATION:
    
    Background
    
        Plagiobothrys hirtus was first collected by Thomas Howell in 1887 
    and described the following year as Allocarya hirta (Greene 1888). 
    Subsequent taxonomic treatments included A. scouleri var. hirta, P. 
    scouleri var. hirtus, A. calycosa, and P. hirtus (Gamon and Kagan 
    1985). Johnston recognized two varieties of the species, P. hirtus var. 
    hirtus and P. hirtus var. collaricarpus (Gamon and Kagan 1985). Later, 
    Chambers (1989) considered the material included in the variety 
    collaricarpus to be a variety of P. figuratus, which elevated the 
    material assigned to P. hirtus var. hirtus to a full species.
        A member of the borage family (Boraginaceae), Plagiobothrys hirtus 
    is an annual herb on drier sites or perennial herb on wetter sites 
    (Amsberry and Meinke 1997). It reaches 30-70 centimeters (cm) (1-2 feet 
    (ft)) in height and has a fairly stout stem with widely spreading, 
    coarse, firm hairs on the upper part. The leaves of the main stem are 
    opposite (paired) and the racemes are paired and without bracts. The 
    individual flowers are 1-2 millimeters (0.4-0.6 inches (in)) wide, and 
    white in color (Gamon and Kagan 1985). It grows in scattered groups and 
    reproduces largely by insect-aided cross-pollination and partially by 
    self-pollination. The species is distinguished from other Plagiobothrys 
    species by coarse, sparse hairs on the stem and branches (Gamon and 
    Kagan 1985).
        Plagiobothrys hirtus grows in open, seasonal wetlands in poorly-
    drained clay or silty clay loam soils (Gamon and Kagan 1985). The taxon 
    is considered dependent on seasonal flooding and/or fire to maintain 
    open habitat and to limit competition with invasive native and alien 
    plant species such as Himalayan blackberry (Rubus discolor), Oregon ash 
    (Fraxinus latifolia), teasel (Dipsacus fullonum), and pennyroyal 
    (Mentha pulegium) (Gamon and Kagan 1985, Almasi and Borgias 1996). 
    Plagiobothrys hirtus occurs in open microsites within the one-sided 
    sedge (Carex unilateralis)--meadow barley (Hordeum brachyantherum) 
    community type within interior valley grasslands. Other frequently 
    associated species include tufted hairgrass (Deschampsia cespitosa), 
    American slough grass (Beckmannia syzigachne), great camas (Camassia 
    leichtlinii var. leichtlinii), water foxtail (Alopecurus geniculatus), 
    baltic rush (Juncus balticus), wild mint (Mentha arvensis), Willamette 
    downingia (Downingia yina), and bentgrass (Agrostis alba) (Gamon and 
    Kagan 1985).
        Plagiobothrys hirtus is endemic to the interior valley of the 
    Umpqua River in southwestern Oregon. The species was collected only 
    four times between 1887 and 1961, all at sites within Douglas County 
    (Gamon and Kagan 1985). The taxon was considered possibly extinct 
    (Meinke 1982) until it was rediscovered in 1983 as a result of 
    intensive field surveys (Jimmy Kagan, Oregon Natural Heritage Program 
    (ONHP), pers. comm. 1997). The location of the first specimen, 
    collected by Howell on June 25, 1887, was given only as the Umpqua 
    Valley (Greene 1888). The sites of collections from 1932 and 1939, were 
    from 16 kilometers (km) (10 miles (mi)) east of Sutherlin and 3 km (2 
    mi) north of Yoncalla, respectively (Siddall and Chambers 1978) . Both 
    sites were surveyed in 1983, but no plants were found (Gamon and Kagan 
    1985). At the time, the sites were heavily grazed by sheep, which lead 
    the botanists to speculate that grazing was the probable cause of 
    extirpation at these sites (Gamon and Kagan 1985). In 1961, a 
    collection was made adjacent to Interstate 5 south of Yoncalla, a site 
    which remains extant today (J. Kagan, pers. comm. 1997).
        Despite the few pre-1961 collections, Plagiobothrys hirtus was 
    probably widespread historically on the floodplains of the interior 
    valleys of the Umpqua River. Because P. hirtus occurs in low-lying 
    areas, seeds were likely dispersed by flood waters, resulting in a 
    patchy clumped distribution on the floodplains (Gamon and Kagan 1985). 
    Natural processes such as flooding and fire maintained open, wetland 
    habitat (Gamon and Kagan 1985). Draining of wetlands for urban and 
    agricultural uses and road and reservoir construction, however, has 
    altered the original hydrology of the valley to such an extent that the 
    total area of suitable habitat for P. hirtus has been significantly 
    reduced. In addition, fire suppression has allowed the invasion of 
    woody and herbaceous species into formerly open wetland habitats (Gamon 
    and Kagan 1985).
        Plagiobothrys hirtus is now limited to 10 known occurrences in the 
    vicinity of Sutherlin and Yoncalla, Oregon (ONHP 1996). All extant 
    populations of this species are small (i.e., fewer than 500 
    individuals) and occur in disjunct habitat. The 10 occurrences are 
    estimated to have a total of about 3,000 individuals and a combined 
    area of less than 4 ha (10 ac) (Amsberry and Meinke 1997).
        All extant populations are at risk of extirpation due to a variety 
    of threats (Almasi and Borgias 1996; J. Kagan, pers. comm. 1997; R. 
    Meinke, Oregon State University, pers. comm. 1997). In addition to the 
    ongoing threat of direct loss of habitat from conversion to urban and 
    agricultural uses, hydrological alterations, and fire suppression, 
    other threats to the species include spring and summer livestock 
    grazing, and roadside mowing, spraying and landscaping (Gamon and Kagan 
    1985, J. Kagan, pers. comm. 1995). Six of the 10 extant occurrences are 
    adjacent to highways. The other four occurrences are in urban or 
    agricultural areas.
        Nine of the 10 known occurrences are on private land. The other 
    population is on public land owned by the Oregon Department of 
    Transportation (ODOT). One of the private parcels is owned and managed 
    for the species by The Nature Conservancy (TNC). The other eight 
    occurrences on private lands have no protective management for the 
    species and are at risk of extirpation from development, incompatible 
    grazing practices, and recreational activities (J.

    Previous Federal Action
    
        Federal action on Plagiobothrys hirtus began when the Secretary of 
    the Smithsonian Institute prepared a report on plants considered to be 
    endangered, threatened, or extinct, pursuant to section 12 of the Act. 
    That 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. The notice further indicated the Service's intention to 
    review the status of the plant species named therein. As a result of 
    this review, the Service published a proposed rule in the Federal 
    Register on June 16, 1976, (41 FR 24523), to determine approximately 
    1,700 vascular plant species to be endangered pursuant to section 4 of 
    the Act. This list, which included P. hirtus, was assembled on the 
    basis of comments and data received by the Smithsonian Institute and 
    the Service in response to House Document No. 94-51 and the July 1, 
    1975 Federal Register publication. 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 (50 FR 82480), including Plagiobothrys hirtus as a 
    category 1 candidate species. Category 1 species were those for which 
    the Service had on file substantial information on biological 
    vulnerability and threats to support preparation of listing proposals. 
    This status was changed to category 2 in the November 28, 1983, 
    supplement to the notice (48 FR 53657), and remained as such in the 
    September 27, 1985, Notice of Review (50 FR 39527). Category 2 species 
    were those for which conclusive data on biological vulnerability and 
    threats were not currently available to support proposed rules. In the 
    February 21, 1990, Notice of Review (55 FR 6185), this status was 
    changed back to category 1. Upon publication of the February 28, 1996, 
    Notice of Review in the Federal Register (61 FR 7596), the Service 
    ceased using category designations and included P. hirtus as a 
    candidate species. Candidate species are those for which the Service 
    has on file sufficient information on biological vulnerability and 
    threats to support proposals to list the species as threatened or 
    endangered.
        Section 4(b)(3)(B) of the Act requires the Secretary to make 
    findings on 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. This was the case for P. hirtus because of the 
    acceptance of the 1975 Smithsonian Report as a petition. On October 13, 
    1983, the Service found that the petitioned listing of this species was 
    warranted, but precluded by other pending listing actions, in 
    accordance with section 4(b)(3)(B)(iii) of the Act; notice 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 annually in October of 1984 
    through 1995. Publication of this proposal constitutes the final 1-year 
    finding for the petitioned action.
        Plagiobothrys hirtus has a listing priority number of 2. Processing 
    of this rule is a Tier 3 activity under the current listing priority 
    guidance.
    
    Summary of Factors Affecting the Species
    
        Section 4 of the Endangered Species Act (16 U.S.C. 1533) 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) of the Act. These factors and their application to 
    Plagiobothrys hirtus Greene (rough popcornflower) are as follows:
        A. The present or threatened destruction, modification, or 
    curtailment of habitat or range. Plagiobothrys hirtus is threatened by 
    destruction and modification of its wetland habitat (R. Meinke, pers. 
    comm. 1997). Although the species is believed to have been more 
    abundant in the past throughout the interior valleys of the Umpqua 
    River, it is now limited to 10 small, isolated occurrences. Direct loss 
    of habitat from hydrological alterations, wetland filling, or 
    conversion to other uses pose a threat to all 10 extant occurrences.
        Two sites occur on private land within the urban boundary of the 
    town of Sutherlin. When first discovered in 1983, these sites were the 
    largest known occurrences (ONHP 1996). One site, with approximately 200 
    individuals in 1983, has since been destroyed and only 1 plant was 
    found in 1996; development of this site is imminent (J. Kagan, pers. 
    comm. 1997). The other site, estimated to have 300-500 plants when 
    discovered in 1983, has been declining since that time. In 1994, a 
    portion of the wetland at the site was filled, and the remaining area 
    was observed to be significantly impacted by mountain bike recreation; 
    only about 50-100 plants were present (J. Kagan, pers. comm. 1995). 
    Urban development of this site is considered likely (J. Kagan, pers. 
    comm. 1997, R. Meinke, pers. comm. 1997).
        Three sites are known on private land about 1.6 km (1 mi) east of 
    Sutherlin. One of these, when discovered in 1983, had about 30-35 
    plants within an area of about 200 square meters (m2) (2,200 
    square feet (ft2)). The site lies within the Sutherlin urban 
    growth boundary and is slated for development (ONHP 1996). The other 
    two sites were discovered in 1986. One of these had 200 plants in 1986, 
    but by 1988 had only 30-40 plants scattered over an area of 25 
    m2 ( 275 ft2). Habitat conditions on this site 
    are described as marginal (ONHP 1996). The other site also had about 
    200 plants when first observed in 1986, but by 1988 had decreased to 
    about 100 plants (ONHP 1996). During the most recent site survey in 
    1993, only 50-100 plants were seen (J. Kagan, pers. comm. 1997).
        Four additional sites are known on private land several kilometers 
    south of the town of Sutherlin. One of these, when discovered in 1983, 
    consisted of about 150 plants growing in an area of about 50 
    m2 (550 ft2). In 1996, only about 50 plants 
    remained. Two other sites were both discovered in 1984. One consisted 
    of 50-60 plants in a 30 m2 (330 ft2) area, and 
    the other had 200-300 plants (ONHP 1996). Both occurrences had 
    generally decreasing numbers of individuals through the late 1980's. 
    TNC acquired a portion of the larger of the two occurrences and began 
    formal monitoring in 1995. Individuals were too numerous for a complete 
    census in 1995 with the total population on the site estimated at over 
    16,000 individuals. In 1996, however, the population plummeted to only 
    394 plants, a drop attributed to an extensive period of standing water 
    on the preserve that year due to a wet spring (Almasi and Borgias 
    1996). See Factor E discussion for further details on this population 
    decline. The fourth site, when discovered in 1990, had fewer than 50 
    plants (J. Kagan, pers. comm. 1995).
    
    [[Page 61956]]
    
        The last site is on public land and private land about 22 km (14 
    mi) north of Sutherlin near the town of Yoncalla. This site is the 
    locality of the 1961 collection that was relocated in 1983. About 200 
    plants were present in 1988, and the population size has continued to 
    increase under management by ODOT. Although the population on public 
    land appears vigorous, a portion of the population on the adjacent 
    private land appears to have vanished (J. Kagan, pers. comm. 1997). 
    Alterations in site hydrology pose the primary threat to the plants (R. 
    Meinke, Oregon State University, pers. comm. 1997).
        B. Overutilization for commercial, recreational, scientific, or 
    educational purposes. No evidence of overutilization of this taxon for 
    any purpose exists at this time. However, the plants are easily 
    accessible by road, and the small population sizes make them vulnerable 
    to overcollection by botanical enthusiasts.
        C. Disease or predation. Grazing has likely been a contributing 
    factor in declining Plagiobothrys hirtus numbers throughout its 
    historic range (Gamon and Kagan 1985). Livestock graze in pastures 
    containing four of the occurrences (ONHP 1996). The timing and 
    intensity of grazing, however, determine the effects of grazing on the 
    plant. Grazing during spring and early summer likely threatens P. 
    hirtus. When herbivores eat the flower or seed head of the plant, the 
    reproductive output for the year for that individual is destroyed. This 
    activity may be more significant at sites where the species functions 
    as an annual (Gamon and Kagan 1985). However, where fires and flooding 
    no longer occur, grazing may benefit the species. Fall grazing, in 
    particular, may be of benefit because the plant is dormant during at 
    this time and grazing can keep the habitat open by reducing the growth 
    of competing species (Gamon and Kagan 1985). By reducing vegetative 
    growth, fall grazing or mowing (see factor E discussion) may also lower 
    the suitability of the habitat for voles and, thereby, reduce herbivory 
    on the plant.
        D. Inadequacy of existing regulatory mechanisms. Under the Oregon 
    Endangered Species Act (ORS 564.100-564.135) and pursuant regulations 
    (OAR 603, Division 73), the Oregon Department of Agriculture has listed 
    Plagiobothrys hirtus as endangered (OAR 603-73-070). This statute 
    prohibits the ``take'' of State-listed plants on State, county, and 
    city owned or leased lands. Most occurrences of P. hirtus occur on 
    private land and are not subject to any current regulations. One site 
    is adjacent to State Route 99 on lands managed by ODOT and has been 
    designated by the agency as a Special Management Area. Mowing and 
    spraying practices have been modified to protect the species at this 
    site where the plant appears to be stable or increasing (N. Testa, 
    Oregon Department of Transportation, pers. comm. 1997).
        E. Other natural or manmade factors affecting its continued 
    existence. Nine of 10 extant sites of Plagiobothrys hirtus occur 
    adjacent to major highways (Interstate 5 and/or State Route 99) or 
    railroad beds. Herbicide spraying and highway landscaping has affected 
    and reduced at least one P. hirtus population (J. Kagan, pers. comm. 
    1995). Mowing is also part of the routine maintenance of roadways. As 
    with livestock grazing, mowing or pesticide spraying during the spring 
    may reduce seed set and thereby negatively affect populations of the 
    plant. Late season mowing has benefited the P. hirtus population at the 
    ODOT site, probably by reducing competition from other plants and 
    herbivory by voles (R. Meinke, pers. comm. 1997). With the exception of 
    the P. hirtus populations in ODOT's Special Management Area and The 
    Nature Conservancy's Popcorn Swale, none of the roadside occurrences 
    are protected from herbicide spraying, landscaping or early season 
    mowing. In addition, roadside occurrences are at risk of toxic chemical 
    spills and runoff containing oil and grease (N. Testa, pers. comm. 
    1997). Vehicle accidents also increase the risk of fuel contamination 
    or fire; such an accident recently occurred adjacent to the ODOT 
    population, but the plant was not affected (N. Testa, pers. comm. 
    1997).
        Encroachment by native and alien plant species increases when 
    natural processes like fire or flooding are altered (J. Kagan, pers. 
    comm. 1997; R. Meinke, pers. comm. 1997). After a 1985 fire at one of 
    the sites in Sutherlin, the plants responded the following year with 
    vigorous growth (J. Kagan, pers. comm. 1997). As with late season 
    grazing or mowing, late season fire is likely to be of benefit, while 
    fire which occurs prior to seed set may have negative consequences to 
    Plagiobothrys hirtus. The encroachment of weedy, and especially woody, 
    species may also alter site hydrology by capturing more of the 
    available water, an alternative explanation for the dramatic collapse 
    of the population at the TNC preserve between 1995 and 1996 (see Factor 
    A; R. Meinke, pers. comm. 1997).
        Because of the small, isolated nature of the occurrences and the 
    few individuals present in most of them, Plagiobothrys hirtus is also 
    more susceptible to random events, such as fires during the growing 
    season, insect or disease outbreaks, or toxic chemical spills. The 
    rapid, and as yet unexplained, collapse of the population at the TNC 
    preserve argues for the protection of all extant sites to shield the 
    species from random events that could cause its extinction. Small, 
    isolated populations may also have an adverse effect on pollinator 
    activity, seed dispersal, and gene flow. The existence of both annual 
    and perennial populations in P. hirtus suggests that some local genetic 
    differentiation may already exist among populations of the species. 
    Genetic drift within small, isolated populations can lead to a loss of 
    genetic variability and a reduced likelihood of long-term viability 
    (Soule in Lesica and Allendorf 1992).
        The Service has carefully assessed the best scientific and 
    commercial information available concerning the past, present, and 
    future threats faced by this species in determining to propose this 
    rule. Based on this evaluation, the preferred action is to list 
    Plagiobothrys hirtus as endangered. Filling of its wetland habitat for 
    development, livestock grazing during its growing season, invasion by 
    competitive plant species as a result of hydrological alteration and 
    fire suppression, and roadside spraying and mowing continue to reduce 
    plant numbers and habitat. The small, isolated occurrences with few 
    individuals make the species more vulnerable. In addition, continued 
    decreases in the number of occurrences and individuals could result in 
    decreased genetic variability. The varied and cumulative threats to P. 
    hirtus indicate the species is in danger of extinction throughout its 
    range. For these reasons, the Service believes that listing P. hirtus 
    as endangered is the most appropriate action. Failure to list this 
    species would likely result in extinction of the species. Threatened 
    status is not appropriate because all of the extant occurrences of P. 
    hirtus are small, and 8 of 10 occurrences have no protection from 
    mowing, herbicide application, imminent urbanization, and grazing 
    threats. In addition, one of the protected occurrences recently 
    suffered a precipitous, and as yet unexplained, reduction in numbers. 
    Not listing the taxon or listing it as threatened would not provide 
    adequate protection and would not be consistent with the Act.
    
    Critical Habitat
    
        Critical habitat is defined in section 3 of the Act as: (i) The 
    specific areas within the geographical area occupied by a species, at 
    the time it is listed in accordance with the Act, on which are found 
    those physical or biological
    
    [[Page 61957]]
    
    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 geographical 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 needed to bring the species to 
    the point at which listing under the Act is no longer necessary.
        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. The Service 
    finds that designation of critical habitat is not prudent for P. 
    hirtus. Service 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.
        Although overutilization is not considered to be a threat to 
    Plagiobothrys hirtus at this time, listing of this species as 
    endangered would publicize its rarity and, thus, can make it more 
    attractive to researchers or collectors of rare plants. Most 
    occurrences are small enough that even limited collecting pressure 
    could have adverse impacts. The Service is also aware of a report that, 
    after the species was listed by the State of Oregon, a landowner 
    contacted by State botanists to discuss protective measures for a 
    population on his property allegedly responded by blading the site and 
    destroying the population (J. Kagan, pers. comm. 1997). The publication 
    of precise maps and descriptions of critical habitat in the Federal 
    Register would make this plant more vulnerable to incidents of 
    collection and/or vandalism and, therefore, contribute to the decline 
    of this species and increase enforcement problems.
        Further, designation of critical habitat for Plagiobothrys hirtus 
    is not prudent for lack of benefit. This plant does not occur on 
    Federal land, and it is not believed to have historically occurred on 
    Federal land. Although a potential nexus for Federal action exists for 
    all occurrences within section 404 of the Clean Water Act and for some 
    occurrences in which the Federal Highway Administration may become 
    involved (see ``Available Conservation Measures'' section below), any 
    such Federal involvement would also require consultation under section 
    7 of the Act. Any action that would adversely modify critical habitat 
    would also jeopardize the continued existence of the species. Most 
    occurrences of this plants are of such small size that a wetland fill 
    less than the 0.13 ha (0.34 ac) regulatory threshold (see ``Available 
    Conservation Measures'' section below) would eliminate it. The 
    designation of critical habitat would not provide additional benefits 
    for this species beyond the protection afforded by listing.
        The Service finds, therefore, that designation of critical habitat 
    for this species is not prudent because such designation would likely 
    increase the degree of threat to the species from vandalism and would 
    provide no additional benefit to the species' protection. Protection of 
    the species' habitat will be addressed primarily through the recovery 
    process.
    
    Available Conservation Measures
    
        Conservation measures provided to species listed as endangered or 
    threatened under the Act include recognition, recovery actions, 
    requirements for Federal protection, and prohibitions against certain 
    practices. Recognition through listing results in public awareness and 
    conservation actions by Federal, State, and local agencies, private 
    organizations, and individuals. The Act provides for possible land 
    acquisition and cooperation with the states and requires that recovery 
    actions be carried out for all listed species. The protection required 
    by Federal agencies and the prohibitions against certain activities 
    involving listed plants are discussed, in part, below.
        Section 7(a) of the Act 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 with the 
    Service on any action that is likely to jeopardize the continued 
    existence of a species proposed for listing or result in destruction or 
    adverse modification of proposed critical habitat. If a species is 
    listed subsequently, section 7(a)(2) requires Federal agencies to 
    ensure that activities they authorize, fund, or carry out are not 
    likely to jeopardize the continued existence of the species or destroy 
    or adversely modify its critical habitat. If a Federal action may 
    affect a listed species or its critical habitat, the responsible 
    Federal agency must enter into consultation with the Service.
        Because Plagiobothrys hirtus occurs in wetlands, regulatory 
    mechanisms under the Clean Water Act apply to this species. Under 
    section 404 of the Clean Water Act, the U.S. Army Corps of Engineers 
    (Corps) regulates the discharge of fill material into the waters of the 
    United States, including wetlands. To be in compliance with the Clean 
    Water Act, potential applicants are required to notify the Corps prior 
    to undertaking any activity that would result in the fill of wetlands 
    under the Corps' jurisdiction (e.g., grading, discharge of soil or 
    other fill material, etc.). Nationwide Permit Number 26 (33 CFR 330.5 
    and 33 CFR 330, App. A) has been issued to regulate the fill of 
    wetlands that are not larger than 1.2 ha (3 ac), nor cause the loss of 
    waters of the United States for a distance of more than 150 linear m 
    (500 linear ft) of streambed (61 FR 65874). Where fill would occur in a 
    wetland less than 0.13 ha (0.34 ac) in size, no requirement exists to 
    notify the Corps prior to fill activities. Where fill would occur in a 
    wetland of 0.13 ha (0.34 ac) to 1.2 ha (3 ac) in size, the Corps 
    circulates for agency comment a predischarge notification to the 
    Service and other interested parties prior to determining whether or 
    not the proposed fill activity qualifies under Nationwide Permit 26. 
    Individual permits are required for the discharge of fill into wetlands 
    that are greater than 1.2 ha (3 ac) in size. The review process for the 
    issuance of individual permits is more extensive, and conditions may be 
    included that require the avoidance or mitigation of environmental 
    impacts. The Corps has discretionary authority and can require an 
    applicant to seek an individual permit if the Corps believes that the 
    resources are sufficiently important, regardless of the wetland's size. 
    In practice, the Corps rarely requires an individual permit when a 
    project would qualify for a Nationwide Permit, unless a federally 
    threatened, endangered, or proposed species occurs on the site. If a 
    federally threatened or endangered species or a proposed species may be 
    affected by a proposed project, the Corps must ensure that it does not 
    authorize, fund or carry out any action that is likely to jeopardize 
    the species' continued existence, pursuant to section 7(a)(2) of the 
    Endangered Species Act. Therefore, if an applicant's project site has 
    one or more listed species on it, the Corps would be required to enter 
    into
    
    [[Page 61958]]
    
    consultation with the Service. Should P. hirtus become listed, the 
    species may be afforded increased protection through consultation on 
    Corps permits.
        In addition, the Federal Highway Administration would become 
    involved with Plagiobothrys hirtus when highway maintenance is funded, 
    even in part, by the Federal government. Any State highway activity 
    being implemented by ODOT that is partly funded by the Federal 
    government would be subject to review under the Act. In addition, 
    Department of Housing and Urban Development projects and Natural 
    Resources Conservation Service projects in areas that presently support 
    P. hirtus would also be subject to review under section 7 of the Act.
        Listing of this plant would provide for development of a recovery 
    plan for the plant. Such a plan would bring together State, Federal and 
    private efforts for conservation of the plant. The plan would establish 
    a framework for agencies to coordinate activities and cooperate with 
    each other in conservation efforts. The plan would set recovery 
    priorities, note responsible parties, and estimate costs of various 
    tasks necessary to accomplish them. It would also describe site-
    specific management actions necessary to achieve conservation and 
    survival of the plant. Additionally, pursuant to section 6 of the Act, 
    the Service would be able to grant funds to Oregon for management 
    actions promoting the protection and recovery of this species.
        Two sites currently receive some protective management. The site 
    owned and managed by ODOT has been designated as a Special Management 
    Area. Mowing is restricted to late in the fall when Plagiobothrys 
    hirtus is dormant (N. Testa, pers. comm. 1997). The other site in 
    protective ownership is owned and managed by TNC. This site, which 
    currently contains about 400 individual plants, is being actively 
    managed for the protection and development of P. hirtus habitat (Almasi 
    and Borgias 1996). Monitoring, life history studies, and 
    transplantation experiments using field-collected seed have been 
    initiated at these two sites. The objectives of these efforts are to 
    increase population sizes, and establish protocols for seed collection, 
    greenhouse propagation, and transplantation techniques (Amsberry and 
    Meinke 1997).
        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, apply. These prohibitions, in part, make it illegal for 
    any person subject to the jurisdiction of the United States to import 
    or export, transport in interstate or foreign commerce in the course of 
    a commercial activity, sell or offer for sale in interstate or foreign 
    commerce, or remove and reduce the species to possession from areas 
    under Federal jurisdiction. In addition, for plants listed as 
    endangered, the Act prohibits the malicious damage or destruction on 
    areas under Federal jurisdiction and the removal, cutting, digging up, 
    or damaging or destroying of such plants in knowing violation of any 
    State law or regulation, including State criminal trespass law. Certain 
    exceptions to the prohibitions apply to agents of the Service and State 
    conservation agencies.
        It is the policy of the Service, published in the Federal Register 
    on July 1, 1994 (59 FR 34272), to identify to the maximum extent 
    practicable at the time a species is listed those activities that would 
    or would not constitute a violation of section 9 of the Act. The intent 
    of this policy is to increase public awareness of the effect of the 
    listing on proposed and ongoing activities within a species' range. 
    Activities that would constitute a violation of section 9 of the Act 
    include removing, damaging or destroying Plagiobothrys hirtus in 
    violation of State law. In addition, collection on Federal lands 
    without a permit and other actions considered to be malicious damage to 
    the species on Federal lands would be prohibited, although P. hirtus is 
    not currently known to occur on Federal lands. Activities that are not 
    likely to violate section 9 of the Act include routine landscape 
    maintenance, clearing of vegetation for firebreaks, and livestock 
    grazing on privately-owned land. Questions regarding whether specific 
    activities may constitute a violation of section 9 should be addressed 
    to the State Supervisor of the Service's Oregon State Office (see 
    ADDRESSES section).
        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 or 
    survival of the species. Requests for copies of the regulations 
    concerning listed plants and animals and general inquiries regarding 
    prohibitions and permits may be addressed to the U.S. Fish and Wildlife 
    Service, Ecological Services, Endangered Species Permits, 911 N.E. 11th 
    Avenue, Portland, Oregon, 97232-4181 (503/231-2063; FAX 503/231-6243).
    
    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 are 
    particularly sought concerning:
    
        (1) Biological, commercial trade, or other relevant data 
    concerning any threat (or lack thereof) to Plagiobothrys hirtus;
        (2) The location of any additional occurrences of this species 
    and the reasons why any habitat should or should not be determined 
    to be critical habitat pursuant to 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 Plagiobothrys hirtus.
    
        Any 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 Act provides for one or more public hearings on this proposal, 
    if requested. Requests must be received within 45 days of the date of 
    publication of the proposal in the Federal Register. Such requests must 
    be made in writing and addressed to the State Supervisor, Oregon State 
    Office (see ADDRESSES section).
    
    National Environmental Policy Act
    
        The Fish and Wildlife Service has determined that Environmental 
    Assessments and Environmental Impact Statements, 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 designation was published in 
    the Federal Register on October 25, 1983 (48 FR 49244).
    
    Required Determinations
    
        The Service has examined this regulation under the Paperwork 
    Reduction Act of 1995, and found it to contain no information 
    collection requirements.
