    SUMMARY: The Fish and Wildlife Service (Service) determines endangered 
    status for Pseudobahia bahiifolia (Hartweg's golden sunburst) and 
    threatened status for Pseudobahia peirsonii (San Joaquin adobe 
    sunburst) pursuant to the Endangered Species Act of 1973, as amended 
    (Act). The two plants occur primarily in nonnative grasslands in the 
    eastern and southeastern portions of the San Joaquin Valley, but also 
    at a few sites at the ecotone between grasslands dominated by nonnative 
    species and blue oak woodland communities. Both plants are threatened 
    primarily by conversion of habitat to residential development. To a 
    lesser extent, the species are variously threatened by agriculture (ag-
    land development), competition from nonnative plants, incompatible 
    grazing practices, transmission line maintenance, recreational 
    activities, mining, road construction and maintenance, a flood control 
    project, and other human impacts. Potential threats include herbicide 
    application to control herbaceous and weedy taxa. This rule implements 
    the Federal protection and recovery provisions afforded by the Act for 
    these species.

    SUPPLEMENTARY INFORMATION:
    
    Background
    
        Pseudobahia bahiifolia (Hartweg's golden sunburst) and Pseudobahia 
    peirsonii (San Joaquin adobe sunburst) are endemic to the nonnative 
    grassland and grassland-blue oak woodland community ecotone of the 
    southern Sacramento Valley and San Joaquin Valley of California. These 
    two valleys comprise the Central Valley. The prehistoric composition of 
    the native grasslands and adjoining plant communities likely will 
    remain a mystery (Brown 1982), although numerous authors have 
    speculated as to the composition of the ``pristine'' flora of the 
    Central Valley (Clements 1934, Munz and Keck 1950, Biswell 1956, 
    Twisselmann 1956, White 1967, McNaughton 1968, Bakker 1971, Ornduff 
    1974, Heady 1977, Bartolome and Gremmill 1981, and Wester 1981). 
    Nonnative annual grasses and forbs invaded the low elevation plant 
    communities of California during the days of the Franciscan 
    missionaries in the 1700's. These nonnative grasses now account for up 
    to 80 percent or more of the floral composition of the grasslands of 
    California (Heady 1956). The nonnative grasses have outcompeted the 
    native flora throughout much of California because these exotics 
    germinate in late fall prior to the germination of the native forbs, 
    including the two sunflower species discussed herein, Pseudobahia 
    bahiifolia and Pseudobahia peirsonii. Each species, however, occurs in 
    a distinctive microhabitat within the larger matrix of nonnative annual 
    grassland. Pseudobahia bahiifolia prefers the top of ``Mima'' mound 
    topography where the grass cover is
    
    [[Page 5543]]
    
    minimal (Stebbins 1991). Vernal pools, an increasingly rare California 
    landform, are often interspersed with the Mima mounds (Stebbins 1991). 
    Pseudobahia peirsonii prefers heavy adobe clay soils where the water 
    retention properties are high.
        Karl Hartweg, a German botanist, first collected Pseudobahia 
    bahiifolia on Cordua's farm near the junction of the Yuba and Feather 
    Rivers in Yuba County, California in April of 1847. George Bentham 
    described the species as Monolopia bahiaefolia in 1849. Edward L. 
    Greene placed the species in the genus Eriophyllum in 1897. In 1915, 
    Per Rydberg established the genus Pseudobahia on the basis of leaf and 
    floral morphology and formed the new combination Pseudobahia 
    bahiaefolia. Dale Johnson (1978) recognized a spelling error in the 
    specific epithet bahiaefolia and used Pseudobahia bahiifolia in his 
    doctoral dissertation.
        Pseudobahia bahiifolia, a member of the sunflower or aster family 
    (Asteraceae), is one of three species of Pseudobahia in the subtribe 
    Eriophyllinae of the tribe Helenieae (Johnson 1978). The species is a 
    few-branched annual about 6 to 15 centimeters (cm) (2 to 6 inches 
    (in.)) tall, covered throughout with white, wooly hairs. Its leaves are 
    narrow, alternate, three-lobed or entire with three blunt teeth at the 
    apex, and about 1 to 2 cm (0.4 to 0.8 in.) long. The bright yellow 
    flower heads, produced in March or April, are solitary at the ends of 
    the branches. The ray flowers are equal in number to the sub-floral 
    bracts (phyllaries) and the pappus is absent. Pseudobahia bahiifolia is 
    distinguished from other members of the genus by having the largest 
    leaves, entire or three-lobed versus once or twice pinnatifid, as in 
    Pseudobahia heermanii and Pseudobahia peirsonii. The range of 
    Pseudobahia bahiifolia is strongly correlated with the distribution of 
    the Amador and Rocklin soil series (Stebbins 1991). Both series 
    generally consist of shallow, well-drained, medium-textured soils that 
    exhibit strong Mima mound microrelief (Stebbins 1991). Such topography 
    is characterized by a series of mounds that may range from 30 cm to 2 
    meters (m) (1.0 to 6.6 feet (ft)) in height and 3 to 30 m (10 to 98 ft) 
    in basal diameter interspersed with shallow basins that may pond water 
    during the rainy season (Bates and Jackson 1987). Pseudobahia 
    bahiifolia nearly always occurs on the north or northeast facing slopes 
    of the mounds, with the highest plant densities on upper slopes with 
    minimal grass cover (Stebbins 1991). A variant of one of the two soil 
    series is concentrated near Friant in Madera County and contains large 
    quantities of pumice, which is mined for use as an industrial binder 
    and is used in making concrete blocks (Chesterman and Schmidt 1956). 
    According to a status survey by John Stebbins (1991), Pseudobahia 
    bahiifolia may have existed throughout the Central Valley of California 
    from Yuba County in the north to Fresno County in the south, a range of 
    approximately 322 kilometers (km) (200 miles (mi)). The plant presently 
    occurs only in the eastern San Joaquin Valley in Stanislaus, Madera, 
    and Fresno Counties, a range of approximately 153 km (95 mi). One 
    population occurs on land owned and managed jointly by the Bureau of 
    Reclamation and a private owner; the remaining populations all occur on 
    privately owned property (California Natural Diversity Data Base 
    (CNDDB) 1996).
        Over 90 percent of all Pseudobahia bahiifolia plants occur in two 
    general locations. One site, in Madera County, approximately 0.8 km 
    (0.5 mile) long and containing about 16,000 plants, is the remnant of 
    one large population that now has become fragmented. The second large 
    population, in Stanislaus County, covers about 2 hectares (ha) (5 acres 
    (ac)) and contains approximately 15,000 plants. Although the number of 
    individuals per population of annual species is highly variable from 
    year to year, 11 of 16 extant populations are very small, and numbered 
    fewer than 200 plants during the 1990 field season (Stebbins 1991).
        Conversion of native habitat to residential development is the 
    primary threat to the existence of Pseudobahia bahiifolia. To a lesser 
    degree, agriculture (ag-land development), competition from aggressive 
    exotic plants, incompatible grazing practices, mining, and other human 
    impacts actions also threaten the species (CNDDB 1996).
        In March 1925, Philip Munz first collected specimens of Pseudobahia 
    peirsonii in a grassy flat near Ducor in Tulare County, California. 
    Until Munz described Pseudobahia peirsonii as a species in 1949, 
    specimens had been included in Monopolia heermani, Eriophyllum 
    heermani, or Pseudobahia heermani, depending on the prevailing 
    treatment of the time (Stebbins 1991). Sherwin Carlquist (1956) and 
    Johnson (1978) supported Munz's taxonomic position with additional 
    morphological and cytological evidence.
        Pseudobahia peirsonii, like Pseudobahia bahiifolia, is a member of 
    the Asteraceae family and is an erect annual herb about 1 to 6 
    decimeters (dm) (4 to 18 in.) tall, loosely covered with white, wooly 
    hairs. Its alternate leaves are twice divided into smaller divisions 
    (bipinnatifid), triangular in outline, and 2 to 6 cm (1 to 3 in.) in 
    length. Flower heads, which appear in March or April, are solitary at 
    the ends of the branches. The ray flowers are bright yellow and equal 
    in number to the subfloral bracts and about 3 millimeters (mm) (0.1 
    in.) long with many disk flowers; the pappus is absent. The dry fruits, 
    called achenes, are black. Pseudobahia peirsonii is distinguished from 
    Pseudobahia heermani, the species most similar in appearance, primarily 
    by its subfloral bracts, which are united only at the base versus 
    united to half their length in the latter species.
        Pseudobahia peirsonii occurs only on heavy adobe clay soils over a 
    range of approximately 193 km (120 mi) through Fresno, Tulare, and Kern 
    counties. One population occurs on land owned and managed by the Fresno 
    Flood Control District; two populations occur on land owned by the U. 
    S. Army Corps of Engineers (Corps); all other populations occur on 
    privately owned land (CNDDB 1996). Stebbins (1991) speculates that the 
    edaphic restriction is associated with the ability of these clay soils 
    to retain moisture longer into the summer dry season. These soils are 
    mainly distributed in the valleys and flats near the foothills of the 
    southeastern San Joaquin Valley (Stebbins 1991). Avena fatua, Brassica 
    kaber, Bromus mollis, Bromus rubens, and Erodium cicutarium are some of 
    the common nonnative associates of Pseudobahia peirsonii (Stebbins 
    1991). The intrusive and aggressive characteristics of herbaceous weedy 
    species appear to be detrimental to habitat quality of this rare plant.
        Pseudobahia peirsonii is concentrated in three major locations--
    east of Fresno in Fresno County; west of Lake Success in Tulare County; 
    and northeast of Bakersfield in Kern County. Of the 36 known 
    occurrences, 20 are small and contain fewer than 250 plants (Stebbins 
    1991; Karen and Gregory Kirkpatrick, KAS Consultants, in litt. 1993; 
    CNDDB 1996). Approximately 80 percent of all plants are contained in 4 
    populations (CNDDB 1996, Mark Mebane, rancher, in litt. 1993). 
    Conversion of natural habitat to residential development is the primary 
    threat to Pseudobahia peirsonii. In addition, road maintenance 
    projects, recreational activities, competition from nonnative plants, 
    ag-land development, incompatible grazing practices, a flood control 
    project, transmission line maintenance, and other human impacts also 
    may threaten the species.

    Previous Federal Action
    
        Federal government actions on these two plants began as a result of 
    section 12 of the Act, which directed the Secretary of the Smithsonian 
    Institution to prepare a report on those plants considered to be 
    endangered, threatened, or extinct in the United States. The report, 
    designated as House Document No. 94-51, was presented to Congress on 
    January 9, 1975. In the report, Pseudobahia bahiifolia was included as 
    a threatened species and Pseudobahia peirsonii as an endangered 
    species.
        On July 1, 1975, the Service published a notice in the Federal 
    Register (40 FR 27823) of its acceptance of the report as a petition 
    within the context of section 4(c)(2) (now section 4(b)(3) of the Act), 
    and its intention thereby to review the status of the plant taxa named 
    therein. Pseudobahia bahiifolia and Pseudobahia peirsonii were included 
    in that notice. 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 to be endangered species pursuant to section 4 
    of the Act. 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. Pseudobahia bahiifolia and the 
    Pseudobahia peirsonii were included in the June 16, 1976 Federal 
    Register document.
        General comments received in relation to the 1976 proposal were 
    summarized in an April 26, 1978, Federal Register publication (43 FR 
    17909). The Act Amendments of 1978 required that all existing proposals 
    over 2 years old be withdrawn. A 1-year grace period was given to those 
    proposals already more than 2 years old. On December 10, 1979, the 
    Service published a notice in the Federal Register (44 FR 70796) of 
    withdrawal of that portion of the June 16, 1976, proposal that had not 
    been made final, along with four proposals that had expired due to a 
    procedural requirement of the 1978 Amendments.
        On December 15, 1980, the Service published a revised Notice of 
    Review of native plants in the Federal Register (45 FR 82480). 
    Pseudobahia bahiifolia and Pseudobahia peirsonii were included as 
    category 1 candidate species, meaning that the Service had in its 
    possession substantial information on biological vulnerability and 
    threats to support preparation of a listing proposal. On November 28, 
    1983, the Service published in the Federal Register (48 FR 53640) a 
    supplement to the 1980 Notice of Review. This supplement treated 
    Pseudobahia bahiifolia and Pseudobahia peirsonii as category 2 species, 
    meaning that the data in the Service's possession indicated listing may 
    be appropriate, but that substantial data on biological vulnerability 
    and threats were not currently known or on file to support preparation 
    of a proposed rule. The plant notice was again revised on September 27, 
    1985 (50 FR 39526). Both species remained in category 2. In the 
    February 21, 1990, revision of the plant notice (55 FR 6184), 
    Pseudobahia bahiifolia remained as a category 2 candidate species and 
    Pseudobahia peirsonii returned to category 1 status. On February 28, 
    1996, the Service published a Notice of Review in the Federal Register 
    (61 FR 7596) that discontinued the designation of category 2 species as 
    candidates.
        Section 4(b)(3)(B) of 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. This was the case for Pseudobahia 
    bahiifolia and Pseudobahia peirsonii because the 1975 Smithsonian 
    report had been accepted as a petition. On October 13, 1983, the 
    Service found that the petitioned listing of these 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 required 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 1991.
        A proposed rule to list Pseudobahia bahiifolia and Pseudobahia 
    peirsonii as endangered was published in the Federal Register on 
    November 30, 1992 (57 FR 56549). That proposal was based, in large 
    part, on the status survey and occurrence data, and information on 
    pending projects that would adversely affect the two species. 
    Pseudobahia bahiifolia was included in the proposal after a review of 
    existing information indicated that the species should be assigned 
    category 1 status and that the proposal for listing was warranted. The 
    Service now determines Pseudobahia bahiifolia to be an endangered 
    species and Pseudobahia peirsonii to be a threatened species with the 
    publication of this rule.
    
    Summary of Comments and Recommendations
    
        In the November 30, 1992, proposed rule (57 FR 56549) and 
    associated notifications, all interested parties were requested to 
    submit factual reports or information to assist the Service in 
    determining whether these two species warrant listing. Appropriate 
    Federal and State agencies, county and city governments, scientific 
    organizations, and other interested parties were contacted and 
    requested to comment. Newspaper notices inviting general comment were 
    published on December 16, 1992, in the Hanford Sentinel, and 
    Porterville Recorder; on December 17, 1992, in the Bakersfield 
    Californian, Fresno Bee, Madera Daily Tribune, Modesto Bee, Union 
    Democrat, and Advance-Register; and on December 18, 1992, in the 
    Visalia Times-Delta. The Service received written requests for a public 
    hearing from Congressman Bill Thomas, Kern County Farm Bureau, Tulare 
    County Cattlemen's Association, and Kern County Cattlemen's 
    Association. As a result, the Service published a notice of a public 
    hearing on April 2, 1993 (58 FR 17376), and extended the deadline for 
    the comment period to May 3, 1993. The Service conducted the public 
    hearing on April 21, 1993, at the Kern County Administrative Center 
    Board Chambers in Bakersfield, California.
        During the comment period, the Service received 28 comments 
    (letters and oral testimony), including representatives from a Federal 
    agency, a State agency, a County agency, and 21 individuals. Eight 
    commenters supported listing, 15 opposed listing or favored delaying 
    the listing, and five were neutral. In addition, several individuals 
    presented oral and written testimony during the public comment period 
    concerning the 1989 Tulare Pseudobahia Species Management Plan, written 
    for the California Department of Fish and Game. This document was not 
    written for the Service, nor was it used to support the Federal listing 
    action of the two species. Comments or portions of comments that were 
    submitted to the Service addressing this plan are considered not 
    substantive and are not considered in the response section of this 
    rule.
        Written comments or oral statements obtained during the public 
    hearing and comment period are combined in the following discussion. 
    Opposing comments and comments questioning the listing have been 
    organized into specific issues. The majority of comments concerned 
    Pseudobahia peirsonii. These issues and the Service's
    
    [[Page 5545]]
    
    response to each are summarized as follows:
    
    Issue 1
    
        The status survey covered only known documented sites; the listing 
    should be delayed until a more thorough survey is conducted.
    Service Response
        The field survey for both species (Stebbins 1991) examined 55 
    previously documented sites. Data from observations at the known sites 
    were used to identify suitable habitat areas to search for undocumented 
    populations of the two species. As a result, 69 additional sites within 
    and adjoining the population concentrations within the ranges of the 
    species were explored. It should be noted that, in cases where access 
    was denied by private landowners of historical sites, these sites were 
    not surveyed. The current status on these sites is unknown. Surveys 
    conducted on Pseudobahia peirsonii after 1990, showed that many 
    populations continued to decrease in size during 1991 and 1992 in spite 
    of increased rainfall (J. Stebbins, California State University, 
    Fresno, pers. comm. 1993). One commenter who supported the listing of 
    Pseudobahia peirsonii, submitted additional population data from an 
    extensive survey conducted in Tulare County in 1992. This information 
    has been incorporated into this rule. This commenter also noted that 
    portions of eastern Kern County contain the only remaining suitable 
    Pseudobahia peirsonii habitat that has not been thoroughly surveyed for 
    the species. A landowner in Kern County commented that he discovered 
    one population that had been presumed extirpated in the status survey, 
    as well as four previously unrecorded populations, the largest of which 
    contained approximately 10,000 plants. Information on all newly 
    recorded populations has been incorporated into this rule. Much of the 
    suitable habitat for these species has been surveyed. In the period of 
    time since the publication of the proposed rule in 1993, no data have 
    been presented to contradict the Service's contention that these 
    species are imperiled by habitat loss and other threats described in 
    the Summary of Factors. The Service believes that sufficient 
    information is available on these species to warrant determination of 
    Pseudobahia bahiifolia as endangered and Pseudobahia peirsonii as 
    threatened.
    
    Issue 2
    
        The Service should consider economic effects in determining whether 
    to list these species under the Act.
    Service Response
        Under section 4(b)(1)(A) of the Act, a listing determination must 
    be based solely on the best scientific and commercial data available. 
    The legislative history of this provision clearly states the intent of 
    Congress to ``ensure'' that listing decisions are ``based solely on 
    biological criteria and to prevent non-biological considerations from 
    affecting such decisions'', H.R. Rep. No. 97-835, 97th Cong. 2d Sess. 
    19 (1982). As further stated in the legislative history, ``Applying 
    economic criteria * * * to any phase of the species listing process is 
    applying economics to the determinations made under section 4 of the 
    Act and is specifically rejected by the inclusion of the word 
    ``solely'' in this legislation.'' H.R. Rep. No. 567, part I, 97th 
    Cong., 2d Sess. 20 (1982).
    
    Issue 3
    
        Extensive grazing poses no threat to Pseudobahia peirsonii. 
    Populations of this species have been grazed for 100 years or more with 
    no adverse effects. Grazing is necessary for the species to compete 
    against aggressive weeds.
    Service Response
        Any assessment of the historical range and population size of the 
    species is complicated by the fact that most records of plant 
    populations were begun after widespread agricultural development had 
    occurred (Stebbins 1991). No range or population data exists for 
    Pseudobahia peirsonii prior to 1925, the year this species was first 
    collected by Phillip Munz. All known extant populations are found in 
    grazed grasslands dominated by nonnative grasses and forbs. Populations 
    not grazed by domestic livestock are unknown. Because the extent and 
    size of populations prior to introduction of domestic livestock is also 
    unknown, it cannot be shown that there has been no historical decline 
    in Pseudobahia peirsonii due to grazing.
        Appropriate grazing practices may, in fact, prove beneficial to 
    Pseudobahia peirsonii. Some populations of Pseudobahia peirsonii appear 
    to be stable under current grazing practices at their sites (CNDDB 
    1996). Grazing reduces the cover and probably the amount of seed 
    produced by weedy species that compete with Pseudobahia peirsonii. 
    Several botanists experienced with Pseudobahia peirsonii commented that 
    ``well-managed, moderate'' grazing is conducive to the survival of the 
    plant and that ``removing the cattle entirely can promote the rapid 
    growth of nonnative plants against which Pseudobahia peirsonii has 
    difficulty competing.'' Timing of grazing also may affect weedy species 
    abundance. A controlled sheep grazing study showed that early spring 
    grazing resulted in a higher frequency of native grasses than did later 
    grazing (Amme and Pitschel 1989).
        Inappropriate grazing practices may, however, be detrimental to the 
    species in several ways. Soil disturbance by grazing animals may allow 
    nonnative or weedy species that are adapted to growing in disturbed 
    sites to become established (Zedler 1987); these species may, for 
    various reasons, have an advantage over Pseudobahia peirsonii in 
    competition for water, light, or nutrients. Excessive trampling by 
    livestock also can degrade habitat by compacting the soil and promoting 
    erosion. Although the palatability of Pseudobahia peirsonii to cattle 
    is unknown, grazing animals are less selective at heavy grazing 
    pressure when less forage is available per animal (Kothmann 1983). Any 
    remaining plants, therefore, have a higher probability of being grazed. 
    This increased grazing pressure in turn affects seed production and can 
    result in population decline (Heady 1961). Reduced population sizes 
    during periods of drought may be more susceptible to the impacts of 
    inappropriate grazing practices. Over half of all known populations of 
    Pseudobahia peirsonii had fewer than 250 individuals in 1991.

        The status survey was conducted in a drought year, which resulted 
    in abnormally low population counts.
    Service Response
        The Service used the best available data at the time the proposal 
    was written. It was not possible to predict the duration of the drought 
    or to postpone the survey until a favorable rainfall year. Although the 
    drought may have had adverse effects on the size of the Pseudobahia 
    peirsonii populations, surveys conducted on Pseudobahia peirsonii after 
    1990 revealed that despite increased rainfall, many populations 
    continued to decrease in size during 1991 and 1992. Observations made 
    in the spring of 1993 showed that most populations covered more area 
    and contained more plants than in previous years; however, extirpated 
    sites did not reappear (J. Stebbins, pers. comm. 1993). Population 
    counts of annual species would be expected to fluctuate yearly 
    according to climatic conditions.
    
    [[Page 5546]]
    
    Moreover, the factors threatening the remaining habitat of these 
    species are not diminished by annual population fluctuations. As stated 
    earlier, no data have been presented to contradict the Service's 
    contention that these species are threatened by factors described in 
    the Summary of Factors.
    
    Issue 5
    
        The sampling period for Pseudobahia peirsonii (1 month during 1 
    year), was too short; more sites may have been found during a longer 
    sampling period.
    Service Response
        Pseudobahia peirsonii and Pseudobahia bahiifolia are small annual 
    plants with a short blooming period of 3 to 4 weeks in March and April. 
    The period of time in which population surveys can be conducted most 
    efficiently is during the blooming period, when the plants are most 
    readily detectible and identifiable. The plants are less visible later 
    in the year as the surrounding vegetation becomes denser and 
    Pseudobahia peirsonii and Pseudobahia bahiifolia begin to produce seed 
    and die. To determine the range of both species, all sites from 
    historical records, as well as potential sites, were surveyed during 
    this 1 month period. The goal of the survey was not to determine actual 
    plant numbers but rather the location, condition, and relative size of 
    the populations and habitat. Actual plant numbers are not as useful an 
    index of population health as is condition of occupied habitat and 
    general population condition. Annual species can vary widely from year 
    to year in numbers of plants due to variation in environmental 
    conditions. The Service believes that the properly-timed survey period 
    during 1990 was appropriate to evaluate the status of both species. No 
    significant distributional data affecting the status of either species 
    has been reported during subsequent surveys. Although several new 
    populations have been reported, most are small, isolated, occur within 
    the known range of the species, and are threatened by the same 
    activities affecting previously known populations.
    
    Issue 6
    
        The status survey was not ``peer-reviewed'' before being accepted 
    by the Service; all data were collected by one botanist and, therefore, 
    subject to personal bias.
    Service Response
        During the compilation of the document, the author of the survey 
    consulted frequently with several respected botanists, all of whom had 
    recent experience with Pseudobahia peirsonii and Pseudobahia 
    bahiifolia. Historical population data were compiled by CNDDB from 
    records dating back to 1897. Field data from 1990 were collected by 
    several technicians and were field checked by the author.
    
    Issue 7
    
        Statements contained in the proposed rule concerning the low 
    numbers of seeds of Pseudobahia bahiifolia and Pseudobahia peirsonii in 
    the seed bank are speculative because no samples were taken.
    Service Response
        Pseudobahia bahiifolia and Pseudobahia peirsonii, when growing in 
    marginal habitats, produce few seeds in comparison to the vigorous seed 
    output of the surrounding nonnative grasses and forbs (Stebbins, pers. 
    comm., 1993). All remaining populations of Pseudobahia bahiifolia and 
    Pseudobahia peirsonii are considered to occur in marginal or degraded 
    habitat dominated by nonnative species and may suffer from reduced seed 
    output resulting from poor physical condition and competition (J. 
    Stebbins, pers. comm., 1993). In addition to proportionally low seed 
    input to the seed bank, the overall seed bank of these two species may 
    become smaller if reduction in population size and consequent reduction 
    in seed production occurs.
    
    Issue 8
    
        No populations of Pseudobahia peirsonii are threatened by highway 
    construction.
    Service Response
        The status of the highway construction projects discussed in the 
    proposed rule has been reviewed. The present status of these projects 
    indicates that they do not pose a threat to the species; the final rule 
    has been revised to reflect this information. Nine populations of 
    Pseudobahia peirsonii, however, are threatened by county and private 
    road maintenance as mentioned under Factor A of Summary of Factors 
    Affecting the Species.
    
    Issue 9
    
        Current zoning laws and economic conditions make future protection 
    an unnecessary duplication of existing regulations.
    Service Response
        As was previously stated in the proposed rule (57 FR 56549), 
    existing State and local regulations are inadequate to protect these 
    species. Nearly all populations of both species occur entirely on 
    private land. State and Federal laws are limited in their ability to 
    regulate potentially detrimental activities on private property. 
    Pseudobahia peirsonii and Pseudobahia bahiifolia are listed as 
    endangered under the Natural Plant Protection Act of 1977 and the 
    California Endangered Species Act of 1984. Although both statutes 
    prohibit the ``take'' of State listed species, State law exempts the 
    taking of plant species via habitat modification or land use change by 
    the landowner. Current county zoning ordinances do not offer protection 
    from land conversion. In each of the five counties in which the two 
    species occur, no ordinances exist that regulate the conversion of land 
    use from grazing to agricultural use. The Madera County General Plan 
    states that the proposed permitted residential development in that 
    county likely will result in the significant degradation or complete 
    elimination of the two populations of Pseudobahia bahiifolia that occur 
    in Madera County (Madera County Planning Department 1994). These 
    populations represent approximately half of all Pseudobahia bahiifolia 
    plants. The majority of habitat loss that has already occurred for both 
    species has been a result of conversion of natural land to agricultural 
    use. Current economic conditions do not represent a safeguard against 
    future development and change in land use.
    
    Issue 10
    
        The status survey on which the listing is partially based was 
    unpublished and not available to the public before the species were 
    proposed to be listed.
    Service Response
        The status survey was prepared to assist the Service in compiling 
    available scientific and commercial information, including additional 
    field surveys and habitat evaluation. The status report was completed 
    in January 1991 and has been available to the public upon request since 
    that time.
    
    Issue 11
    
        Methods used to collect population data for the status survey were 
    not scientific and not described.
    Service Response
        The method used to examine the populations of both species was a 
    meandering transect (Stebbins, pers. comm. 1993). This is an 
    established method for surveying for rare plant species (Nelson 1985). 
    Population data consisting of numbers and size class
    
    [[Page 5547]]
    
    distribution of individual plants were collected. Additionally, data 
    relating to physical site characteristics, physiographic and 
    topographic characteristics, edaphic and erosion factors, and 
    vegetation type and associated species were collected and discussed in 
    the status survey (Stebbins 1991). These environmental characteristics 
    are widely accepted as important information upon which to partially 
    determine habitat viability and suitability, and population threats.
    
    Issue 12
    
        Threats to Pseudobahia peirsonii from agriculture are opinions of 
    the author of the status survey and are not supported by facts.
    Service Response
        Historically, many populations of both species have probably been 
    lost to agriculture. Pseudobahia peirsonii is restricted to the heavy 
    clay soil type found in the valleys and flats which is used for row 
    crops and orchards. With increased irrigation, foothill areas also are 
    being converted for agriculture. Of the 30 historic populations of this 
    species surveyed in 1990, eight were found to have been extirpated due 
    to conversion of land use to agriculture (Stebbins 1991). Six remaining 
    populations are adjacent to farm land and may be converted to 
    agricultural use in the future. Several other sites currently are used 
    only for grazing, but also could face conversion to agriculture because 
    of proximity to active agricultural land.
    
    Summary of Factors Affecting the Species
    
        Section 4 of the 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 of 
    endangered and threatened species. 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 
    Pseudobahia bahiifolia (Bentham) Rydberg (Hartweg's golden sunburst) 
    and Pseudobahia peirsonii Munz (San Joaquin adobe sunburst) are as 
    follows:
        A. The present or threatened destruction, modification, or 
    curtailment of its habitat or range. Pseudobahia bahiifolia and 
    Pseudobahia peirsonii are restricted to specific habitats in nonnative 
    valley grassland and occasionally the grassland-woodland ecotone of the 
    San Joaquin Valley and neighboring foothills. The primary threat facing 
    the two plants is ongoing and threatened destruction and adverse 
    modification of their habitat. The habitat of the two species is being 
    threatened or eliminated primarily by residential development. Ag-land 
    development, a flood control project, competition from nonnative 
    plants, incompatible grazing practices, mining, recreational activities 
    (including ORVs), transmission line maintenance, road maintenance, and 
    other human impacts pose threats to these species.
        Urbanization and ag-land development eliminated the type locality 
    in Yuba County, the only documented occurrence of this plant in the 
    Sacramento Valley. The species likely was extirpated in the area 
    between Stanislaus and Yuba counties before other collections were 
    documented, as valley soils in this area were rapidly converted to 
    agricultural use in the late 1800's (Stebbins 1991). Pseudobahia 
    bahiifolia is now known only from 16 sites in two localized areas in 
    the eastern portion of the San Joaquin Valley--the Friant region in 
    Madera and Fresno counties, and the Cooperstown-La Grange region in 
    Stanislaus County (CNDDB 1996). Habitat alteration from residential 
    development, ag-land development, ORVs, and mining threatens 
    populations of Pseudobahia bahiifolia in all three counties.
        Two historical occurrences of Pseudobahia bahiifolia have been 
    eliminated or seriously degraded in Madera County by conversion to 
    orchards, mining, unauthorized dumping, and grazing. The remaining 
    populations in Madera County are threatened by residential development. 
    The Madera County General Plan states that the proposed permitted 
    residential development in that county will likely result in the 
    complete elimination or significant degradation of the two populations 
    that occur in Madera County (Madera County Planning Department 1995). 
    These populations represent approximately half of all Pseudobahia 
    bahiifolia plants. Habitat supporting the plants is proposed to be 
    replaced by low density residential housing. In addition, these Madera 
    County occurrences are threatened by quarry activities and ORV use 
    (Stebbins 1991). The largest of these two populations, containing 
    approximately 16,000 plants, is located 0.3 km (0.2 mi) north of a 
    pumicite quarry. Ongoing quarry operations and associated ORV use may 
    damage this population, which likely represents a fragment of an even 
    larger population that once occurred west of Cottonwood Creek and east 
    of State Route 145, north of the San Joaquin River at Friant Bridge. 
    Off road vehicle use occurs throughout the area (Stebbins 1991). A 
    similar quarry in Stanislaus County is located 0.4 km (0.25 mi) east of 
    the second largest population of Pseudobahia bahiifolia. Although there 
    are no current plans to expand either mining operation, the threat of 
    expansion is dependent on product demand.
        In Fresno County, one population grows on three land parcels, two 
    of which are protected. One parcel is jointly managed by the U.S. 
    Bureau of Reclamation and The Nature Conservancy and one parcel is 
    protected by conservation easement. The third parcel is in private 
    ownership and is threatened by incompatible grazing practices and 
    residential development. The other Fresno County population occurs 
    entirely on private lands. Both privately-held Fresno County 
    occurrences are threatened by urbanization associated with the 
    ``Millerton New Town'' development, the Friant Redevelopment Plan, 
    incompatible grazing practices, and water tank access and maintenance 
    (Stebbins 1991).
        In the Cooperstown-La Grange area of Stanislaus County, three of 
    the remaining 12 occurrences are variously threatened by ORV, 
    incompatible grazing practices, erosion resulting from over grazing, 
    potential quarry expansion, and ag-land development (Stebbins 1991). At 
    one of the three threatened sites, habitat was present but no 
    Pseudobahia bahiifolia plants were found during the 1990 survey. The 
    remaining nine populations, all of which occur on private land, are 
    small, containing less than 250 plants each. Although the populations 
    appear to be stable under current grazing practices, they may suffer if 
    grazing pressures or land use is changed.
        Pseudobahia peirsonii is known from 36 sites in Fresno, Tulare, and 
    Kern counties (Stebbins 1991; K. and G. Kirkpatrick, in litt. 1993; M. 
    Mebane, in litt. 1993; CNDDB, 1996). Habitat loss and alteration from 
    increased urbanization are the primary threats to Pseudobahia 
    peirsonii. Transmission line maintenance, ag-land development, water 
    projects, inappropriate grazing practices, and road construction and 
    maintenance also threaten populations of this species. These activities 
    collectively have reduced the species to a small number of isolated 
    colonies that occur in three areas in three counties in the 
    southeastern portion of the San Joaquin Valley--the Round Mountain 
    region in Fresno County, the Porterville-Fountain Springs region in 
    Tulare County, and the Pine Mountain-Woody
    
    [[Page 5548]]
    
    region in Kern County. Ag-land development, urbanization, flooding and 
    shore erosion at Lake Success, recreational activities, grazing, and 
    water projects have extirpated eight historical occurrences, all of 
    which were in Tulare County.
        Until recently, two of the largest known populations of Pseudobahia 
    peirsonii, comprising approximately 34 percent of all plants of this 
    species, were found in Fresno County. Both populations have now been 
    impacted by habitat alteration. The largest population, containing 
    approximately 5,000 plants spread over 1.2 hectares (ha) (3 acres 
    (ac)), is being impacted by a large, residential project (Quail Lakes) 
    and an adjacent, recreational water park (Clovis Lakes). The Quail 
    Lakes project, currently under construction, consists of a 20.4 ha (51-
    ac) lake and 730 housing units spread over 152 ha (375 ac) (Valley 
    Planning Consultants, Inc. 1993, EIP 1993). Part of the mitigation for 
    the project includes preservation of the two highest density of four 
    subpopulations of Pseudobahia peirsonii on the site and the 
    establishment of a third new subpopulation using topsoil salvaged from 
    an area to be destroyed. The salvaged topsoil would be planted with 
    seeds collected from a high density population eliminated by the 
    project. The success of the proposed mitigation is unknown. Frequently, 
    propagation of rare species is not successful. In a study funded by 
    California Department of Fish and Game (CDFG), the success of 40 
    projects attempting to transplant, relocate, or reintroduce endangered 
    or threatened plant species in California, was evaluated; only 20 
    percent of the projects were deemed fully successful (Fiedler 1991).
        The second largest population of Pseudobahia peirsonii, also 
    located in Fresno County, had nearly 4,500 plants spread over 17 ha (42 
    ac), and was located in the Fancher Creek Reservoir Project Area. The 
    Fancher Creek Reservoir Project was constructed several years ago by 
    the Fresno Metropolitan Flood Control District to temporarily detain 
    water during flood periods. which it has done at various times over the 
    past two years. The project was predicted to impact approximately 40 
    percent of this population (Jones and Stokes 1990). The three other 
    Fresno County sites are threatened variously by the proposed 
    residential expansion in the greater Fresno area, ag-land development, 
    incompatible grazing practices, competition from nonnative plants, and 
    livestock trampling (Stebbins 1991).
        Most Tulare County populations of Pseudobahia peirsonii lie in the 
    Porterville-Fountain Springs area, although several small, isolated 
    populations recently have been discovered in the northern part of the 
    county (K. and G. Kirkpatrick, in litt. 1993). Maintenance and repair 
    of the Southern California Edison transmission lines pose a potential 
    threat to two Tulare County populations of Pseudobahia peirsonii 
    located under the transmission line right-of-way south of Fountain 
    Springs. Another population, located near the high water line at Lake 
    Success east of Porterville could be impacted or extirpated by 
    inundation or erosion resulting from a rise in water level. Although 
    the Corps has no current plans to increase water storage, such a 
    project has been proposed in the recent past.
        Numerous other human impacts threaten populations of Pseudobahia 
    peirsonii. In Fresno County, potentially harmful runoff from State 
    Route 180 may impact a population growing on both sides of the highway 
    on the soft shoulder (Stebbins 1991). Road stabilization and 
    maintenance practices threaten four populations in Kern County, three 
    in Tulare County, and two in Fresno County (Stebbins 1991; K. and G. 
    Kirkpatrick, in litt., 1993; CNDDB 1996). Off road vehicle use and 
    hiking threaten one population of approximately 200 plants spread over 
    1.2 ha (3 ac) in Tulare County.
        B. Overutilization for commercial, recreational, scientific, or 
    educational purposes. There are no known significant existing or 
    potential threats to Pseudobahia bahiifolia and Pseudobahia peirsonii 
    as a result of these activities. However, the increased publicity 
    associated with proposing these species may make them attractive to 
    researchers and collectors of rare plants.
        C. Disease or predation. Pseudobahia bahiifolia and Pseudobahia 
    peirsonii have been subjected to various levels of livestock grazing. 
    Several populations of Pseudobahia peirsonii appear to be stable under 
    the current grazing practices on their sites (CNDDB 1996). Stebbins 
    (1991) concluded that moderate levels of grazing help to control the 
    aggressive nonnative forbs and grasses against which Pseudobahia 
    bahiifolia and Pseudobahia peirsonii must compete in their respective 
    habitat areas. Others have also noted that livestock grazing appears to 
    be compatible and possibly beneficial to Pseudobahia peirsonii if 
    managed properly, and that the biggest threat to the species comes not 
    from routine and moderate grazing practices, but from land conversion 
    or extensive overgrazing of the population sites (K. and G. 
    Kirkpatrick, in litt., 1993; R. Hansen, in litt., 1993; T. Mallory, in 
    litt., 1993). Both Pseudobahia species may benefit, in particular, from 
    a reduction of grazing levels during flowering and fruiting in March 
    and April. Excessive trampling of the plants by livestock may also be 
    detrimental because of direct and indirect effects of soil compaction 
    on soil-water relations and erosion. One historical occurrence in 
    Tulare County of Pseudobahia peirsonii is thought to have been 
    extirpated by incompatible grazing practices (Stebbins 1991).
        D. The inadequacy of existing regulatory mechanisms. Nearly all 
    populations of both plants occur entirely on private land. State and 
    Federal laws are limited in their ability to regulate potentially 
    detrimental human activities on private property (Clausen 1989). For 
    example, local zoning ordinances in the five counties in which both 
    species occur, do not regulate the conversion of open rangeland to ag-
    land. Under the Native Plant Protection Act of 1977 (Chapter 10 
    Sec. 1900 et seq. of the California Fish and Game Code) and California 
    Endangered Species Act of 1984 (Chapter 1.5 Sec. 2050 et seq.), the 
    California Fish and Game Commission has listed both Pseudobahia 
    bahiifolia and Pseudobahia peirsonii as endangered (14 California Code 
    of Regulations Section 670.2). Though both statutes prohibit the 
    ``take'' of State-listed plants (Chapter 10 Sec. 1908 and Chapter 1.5 
    Sec. 2080), State law exempts the taking of such plants via habitat 
    modification or land use change by the landowner. After the CDFG 
    notifies a landowner that a State-listed plant grows on his or her 
    property, State law requires only that the landowner notify the agency 
    ``at least 10 days in advance of changing the land use to allow 
    possible salvage of such plant.'' (Chapter 10 Sec. 1913).
        The California Environmental Quality Act (CEQA) requires a full 
    public disclosure of the potential environmental impacts of proposed 
    projects. The public agency with primary authority or jurisdiction over 
    the project is designated as the lead agency, and is responsible for 
    conducting a review of the project and consulting with other agencies 
    concerned with resources affected by the project. Section 15065 of the 
    CEQA Guidelines requires a finding of significance if a project has the 
    potential to ``reduce the number or restrict the range of a rare or 
    endangered plant or animal.'' Once significant impacts are identified, 
    the project agency has the option to require mitigation for effects 
    through changes in the project or to decide that overriding 
    considerations
    
    [[Page 5549]]
    
    make mitigation infeasible. In the latter case, projects may be 
    approved that cause significant environmental damage, such as 
    destruction of endangered species. Protection of listed species through 
    CEQA is therefore at the discretion of the project agency involved.
        E. Other natural or manmade factors affecting its continued 
    existence. The typical variation in rainfall characteristics of the 
    regional climate very likely will subject populations of both species 
    to periodic drought, which may threaten the remaining small, marginal 
    populations of both species. Marginal habitat conditions and past 
    disturbances could exacerbate already critically low population sizes 
    and decrease the amount and/or viability of stored seed banks for both 
    species. Annuals and other monocarpic plants (individuals that die 
    after flowering and fruiting), like both species considered herein, may 
    be more vulnerable to random fluctuations or variation (stochasticity) 
    in annual weather patterns and other environmental factors than plant 
    species with different life histories (Huenneke et al. 1986). Fifty 
    percent of all populations of both species have been observed with 
    fewer than 100 plants, which may make them more vulnerable to random 
    chance extirpation (Stebbins 1991, K. and G. Kirkpatrick, in litt. 
    1993). Moreover, nonnative species germinate in late fall and likely 
    outcompete Pseudobahia bahiifolia and Pseudobahia peirsonii for 
    sunlight, nutrients, and water. Competition from nonnative plants 
    threatens the Pseudobahia bahiifolia population at the botanical 
    preserve in Fresno County (Rosalie Faubion, U.S. Bureau of Reclamation, 
    pers. comm. 1992). Competition from nonnative plants also threatens 
    four occurrences of Pseudobahia peirsonii in Tulare County (Stebbins 
    1991, K. and G. Kirkpatrick, in litt. 1993). The invasion of nonnative 
    plants likely has been a significant factor in the degradation of the 
    habitat of both plants throughout their respective ranges (Heady 1977, 
    Amme and Pitschel 1989).
        The Service has assessed carefully the best scientific and 
    commercial information available regarding the past, present, and 
    future threats faced by both species in determining to make this rule 
    final. Based on this evaluation, the preferred action is to list 
    Pseudobahia bahiifolia as endangered and Pseudobahia peirsonii as 
    threatened. Both species occupy specific habitat within a restricted 
    geographic area. All remaining populations of both species are 
    considered to occur in marginal or degraded habitat (J. Stebbins, pers. 
    comm. 1993). Remaining habitat is highly fragmented and most remaining 
    populations are quite small. The largest populations of both species 
    are imminently threatened by residential development. In addition, a 
    significant portion of the remaining range of both species is 
    threatened by ag-land development, a flood control project, mining, 
    grazing, and competition from nonnative species.
        Over 90 percent of all Pseudobahia bahiifolia plants occur in two 
    general locations. One site, approximately 0.8 km (0.5 mi) long and 
    containing about 16,000 plants, is the remnant of one large population 
    that now has become fragmented. This occurrence, representing 
    approximately half of all plants of this species, is proposed to be 
    eliminated by a residential development project. The second large 
    population contains approximately 15,000 plants and is located 0.4 km 
    (0.25 mi) from a quarry. Although there are no current plans to expand 
    the quarry, the threat of quarry expansion is dependent on product 
    demand. Moreover, degradation from off-road vehicle use on these sites 
    is on-going. Grazing occurs at both locations and appears to be 
    accelerating soil erosion at the smaller site. Neither of these two 
    sites is protected.
        Over 80 percent of Pseudobahia peirsonii plants occur at 4 sites; 
    32 additional smaller sites contain 1,000 plants or fewer. The Quail 
    Lakes population, largest of all known populations with 18 percent of 
    the total plant population, is being impacted by urban development. The 
    second largest population, with 16 percent of the total plant 
    population, lies in the Fancher Creek Flood Control Project area. This 
    project, completed several years ago, was predicted to impact 40 
    percent of the population. Gradual conversion of range land in eastern 
    San Joaquin Valley to residential use also threatens the species (J. 
    Stebbins pers. comm. 1996). Anthropogenic actions have degraded and 
    reduced the habitat of most of the remaining populations. As a result, 
    Pseudobahia bahiifolia is in danger of extinction and Pseudobahia 
    peirsonii is likely to become in danger of extinction within the 
    foreseeable future throughout all or a significant portion of their 
    ranges.
    
    Critical Habitat
    
        Critical habitat is defined in section 3 of the Act as: (1) 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 features (I) essential to the conservation 
    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 requires that, to the maximum extent 
    prudent and determinable, the Secretary designate critical habitat 
    concurrently with determining a species to be endangered or threatened. 
    The Service finds that the determination of critical habitat is not 
    prudent for either species at this time. Because the two species face 
    numerous anthropogenic threats (see Factor A, Factor C, and Factor E in 
    the ``Summary of Factors Affecting the Species'') and occur 
    predominantly on private land, the publication of precise maps and 
    descriptions of critical habitat in the Federal Register would make 
    both plants more vulnerable to incidents of vandalism and, therefore, 
    could contribute to the decline of the two plants. The listing of these 
    species also publicizes the rarity of the plants and, thus, may make 
    them attractive to researchers or collectors of rare plants. The proper 
    agencies will be notified of the location and importance of protecting 
    the habitat of both species. Protection of both species' habitat will 
    be addressed through the recovery process and through the section 7 
    consultation 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 
    activities. Recognition through listing encourages and results in 
    conservation actions by Federal, State, and private agencies, groups, 
    and individuals. The Act provides for land acquisition and cooperation 
    with the State and requires that recovery actions be carried out for 
    all listed species. Such actions are initiated by the Service following 
    listing. The protection required of 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
    
    [[Page 5550]]
    
    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 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 
    ensure 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.
        Federal involvement for these species is expected to include the 
    U.S. Bureau of Reclamation, which operates, as part of the Central 
    Valley Project, the Friant-Kern canal system located within 0.4 km 
    (0.25 mile) of six Pseudobahia bahiifolia and two Pseudobahia peirsonii 
    populations. In addition, the Corps operates the facilities at Lake 
    Success located within 0.8 km (0.50 mi) of three Pseudobahia peirsonii 
    colonies and sponsored the Redbank-Fancher Creek Flood Control Project, 
    which currently impacts another Pseudobahia peirsonii colony near Round 
    Mountain. Any future construction or maintenance activities on these 
    government projects that may affect the plant populations, as well as 
    water contract renewals, would require section 7 consultation with the 
    Service. The Service may develop, in cooperation with other 
    knowledgeable parties, grazing recommendations for habitats supporting 
    the two species. The goal of the recommendations would be to encourage 
    grazing practices which, if implemented, would benefit growth and 
    reproduction of Pseudobahia bahiifolia and Pseudobahia peirsonii.
        A Pseudobahia bahiifolia population in Fresno County is provided 
    some protection on one parcel by joint management by The Nature 
    Conservancy (TNC) and the Bureau of Reclamation, and on a second parcel 
    by a conservation easement between a private landowner and TNC. This 
    site is difficult to protect, however, because of its proximity to 
    residential housing, the Friant-Kern Canal, and a Friant water tank.
        The Act and its implementing regulations found at 50 CFR 17.61, 
    17.62, and 17.63 for endangered plant species and 17.71 and 17.72 for 
    threatened plant species set forth a series of general prohibitions and 
    exceptions that apply to all endangered or threatened plants. With 
    respect to Pseudobahia bahiifolia and Pseudobahia peirsonii, all trade 
    prohibitions of sections 9(a)(2) of the Act, implemented by 50 CFR 
    17.61 or 17.71, would apply. These prohibitions, in part, make it 
    illegal for any person subject to the jurisdiction of the United States 
    to import or export, deliver, receive, carry, transport or ship in 
    interstate or foreign commerce in the course of a commercial activity, 
    sell or offer for sale these species in interstate or foreign commerce; 
    or remove and reduce to possession these species from areas under 
    Federal jurisdiction. Other prohibitions of section 9(a)(2) of the Act 
    make it illegal to maliciously damage or destroy any such plant species 
    on any area under Federal jurisdiction; or to remove, cut, dig up, 
    damage, or destroy any such plant 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 can 
    apply to agents of the Service and State conservation agencies. The Act 
    and 50 CFR 17.62, 17.63, and 17.72 also provides for the issuance of 
    permits to carry out otherwise prohibited activities involving 
    endangered or threatened plant species under certain circumstances. The 
    Service anticipates few trade permits would ever be sought or issued 
    for the two species because the plants are not common in cultivation or 
    in the wild.
        It is the policy of the Service (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. Populations of both species occur on Federal lands. 
    Collection, damage, or destruction of the two species on Federal lands 
    is prohibited, although, in appropriate cases, a Federal endangered 
    species permit may be issued to allow collection for scientific or 
    recovery purposes. Such activities on non-Federal lands would 
    constitute a violation of California State laws or regulations. 
    California law requires a ten day notice be given before taking of 
    plants on private land. Activities, such as landscape maintenance, and 
    clearing vegetation for firebreaks, and livestock grazing on privately-
    owned lands not under Federal funding or authorization, would not be 
    considered a violation of section 9 of the Act.
        Questions regarding whether specific activities will constitute a 
    violation of section 9 should be directed to the Field Supervisor of 
    the Service's Sacramento Field Office. Requests for copies of the 
    regulations on plants and inquires regarding them 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 
    (phone 503/231-2063, facsimile 503/231-6243).
    
    National Environmental Policy Act
    
        The Fish and Wildlife Service has determined that Environmental 
    Assessments or 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 Act. A notice outlining the Service's reasons for this 
    determination 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. This rulemaking was not subject to review by the Office 
    of Management and Budget under Executive Order 12866.
