Endangered and Threatened Wildlife and Plants; Proposed
Endangered Status for the Plant Thlaspi Californicum (Kneeland Prairie
Penny-Cress) From Coastal Northern California
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The U.S. Fish and Wildlife Service (Service) proposes
endangered status pursuant to the Endangered Species Act of 1973, as
amended (Act), for the plant Thlaspi californicum (Kneeland Prairie
penny-cress). Thlaspi californicum is known from Kneeland Prairie in
Humboldt County, California, where it grows in coastal prairie on
serpentine outcrops. The Service considers the occurrences of T.
californicum reported from Mendocino County to be T. montanum, a widely
distributed species. Habitat loss, potential road realignment, and
proposed airport expansion activities imperil the continued existence
of T. californicum. The restricted range of this species, limited to a
single population, increases the risk of extinction from naturally
occurring events such as fire. This proposed rule, if made final, would
extend Federal protection under the Act to this plant species.
DATES: To ensure consideration in the development of a final decision-
making document for this species, comments from all interested parties
should be received by April 13, 1998. Public hearing requests must be
received by March 30, 1998.
ADDRESSES: Comments and materials concerning this proposal should be
sent to the Field Supervisor, Sacramento Fish and Wildlife Office, U.S.
Fish and Wildlife Service, 3310 El Camino Avenue, Sacramento,
California 95821-6340. Comments and materials received, as well as the
supporting documentation used in preparing the rule, will be available
for public inspection, by appointment, during normal business hours at
the above address.

Wildlife Office (see ADDRESSES section) (telephone 916/979-2120;

SUPPLEMENTARY INFORMATION:
Background
Thlaspi californicum is found on serpentine soils at a coastal
prairie in Humboldt County, California. Serpentine soils are derived
from ultramafic rocks such as serpentinite, dunite, and peridotite,
which are found in discontinuous outcrops in the Sierra Nevada and
Coast Ranges of California from Santa Barbara County to Humboldt
County. The chief constituent of the parent rock is a variant of iron-
magnesium silicate. Most serpentine soils are formed in place over the
parent rock, and are therefore shallow, rocky, and highly erodible.
Serpentine soils, because of the parent material, tend to have high
concentrations of magnesium, chromium, and nickel, and low
concentrations of calcium, nitrogen, potassium, and phosphorus
(Kruckeberg 1984). These characteristics make serpentine soil
inhospitable for the growth of most plants, but some plants have
adapted to serpentine substrates.
Sereno Watson (1892) described Thlaspi californicum based on
material collected by Volney Rattan from Kneeland Prairie at 760 meters
(m) (2,500 feet (ft)) elevation in Humboldt County, California. Payson
(1926) maintained it as a full species in his monograph of the genus,
whereas it was referred to as T. alpestre var. californicum in Jepson's
(1925) manual, and T. glaucum ssp. californicum by Munz (1959).
Holmgren (1971) assigned the name Thlaspi montanum var. californicum
and gave its range as Kneeland Prairie (including a 1952 specimen from
a ``serpentine rockpile toward Ashfield Butte''). She noted that the
plant had last been collected in 1962. Rollins (1993a, 1993b) has
elevated it to a full species: Thlaspi californicum.
Thlaspi californicum is a perennial herb in the mustard family
(Brassicaceae) that grows from 9.5 to 12.5 centimeters (cm) (3 to 6
inches (in)) tall, with a basal rosette. The margins of the basal
leaves range from entire to toothed. The white flowers have strongly
ascending pedicels (flower stalks). The fruit is a sharply pointed
silicle (a short fruit typically no more than 2 to 3 times longer than
wide). Thlaspi californicum flowers from May to June. Characteristics
that separate T. californicum from T. montanum include the orientation
of the pedicel, shape and notching of the fruit, and length/width ratio
of the fruit. Thlaspi montanum has pedicels perpendicular to the stem,
not strongly ascending, and the silicles are either truncate or
shallowly notched, but not acute at the apex as they are in T.
californicum (Meyers 1991).
Rollins (1993a, 1993b) and Holmgren (1971) considered Thlaspi
californicum to occur only at Kneeland Prairie. Wheeler and Smith
(1991), in their ``Flora of Mendocino County,'' reported two additional
occurrences of T. californicum located on Mendocino National Forest in
Mendocino County. These sites have been examined by Dave Isle,
Mendocino National Forest botanist; Dave Imper, Environmental
Specialist with SHN Consulting Engineers and Geologists; and Service
staff. In addition, all of the herbarium specimens for T. californicum
and T. montanum at Humboldt State University, including those collected
in Mendocino County, have been examined by Imper and Service staff. The
only collections considered by Imper and the Service to be T.
californicum are from Kneeland Prairie in Humboldt County (Imper 1997;
Larry Host and Kirsten Tarp, U.S. Fish and Wildlife Service (USFWS),
pers. comms., 1997). Plants from Blue Banks and near the Spruce Grove
campground on the Mendocino National Forest have pedicels that are
perpendicular to the stem and silicles that are truncate and notched,
characteristic of T. montanum. Additionally, the habitat and elevation
are different from Kneeland Prairie. Other herbarium specimens, housed
at the Humboldt State University herbarium and collected from Blue
Banks and from Spruce Grove campground, are identified as T. montanum.
McCarten (1991) did not
[[Page 7113]]
find any T. californicum in his habitat management study of rare plants
and communities associated with serpentine soils on the Mendocino
National Forest. The Mendocino National Forest botanist and the
botanical consultant for Humboldt County concurred with this conclusion
(Imper 1997; Dave Isle, botanist, Mendocino National Forest, pers.
comm., 1997; L. Host and K. Tarp, pers. comms., 1997).
The California Natural Diversity Database (CNDDB) includes one
occurrence for Thlaspi californicum based on Constance & Rollins'
collection #2877 from 1942 (``5 mi s of Hoopa Valley''), housed at the
Humboldt State University herbarium. The specimen had been annotated as
T. californicum in 1976 by T. Nelson, then the herbarium's curator. A
duplicate of this specimen, housed at another herbarium, had been
assigned to T. montanum var. montanum by Patricia Holmgren in her 1971
biosystematic study of North American T. montanum and its allies. The
specimen has since been examined by Imper and Service staff, who concur
that it is T. montanum (Meyers 1991, Imper 1997).
The only known population of Thlaspi californicum is scattered
within an area of 0.25 hectare (ha) (0.6 acre (ac)), with a total of
about 11,000 individuals at Kneeland Prairie in Humboldt County (Dave
Imper, Environmental Specialist, SHN Consulting Engineers and
Geologists, pers. comm., 1997). The Kneeland Prairie population is
bisected into two colonies by the Kneeland Airport. Both colonies occur
on private land immediately adjacent to the Kneeland Airport. At
Kneeland Prairie, the habitat for T. californicum has been reduced by
approximately 60 to 70 percent within the past 33 years (CNDDB 1990,
Meyer 1991, Imper 1997). This population is currently threatened by the
proposed expansion of the County airport and potential realignment of
the adjacent road. Because of its extremely restricted range, the plant
is also vulnerable to extinction from naturally occurring events such
as fire (CNDDB 1997).
In order to assess the significance of the Kneeland prairie
population to the species, Imper (1997) inspected potentially suitable
habitat for Thlaspi californicum in other areas near Kneeland Prairie
and to the south. He found no other occurrences. Additionally, T.
californicum has been targeted for surveys by the Bureau of Land
Management (BLM) and U.S. Forest Service staff. The Six Rivers National
Forest has no documented occurrences (Lisa Hoover, botanist, Six Rivers
National Forest, pers. comm., 1997). A search for the species has not
revealed any T. californicum on the serpentine at Iaqua Buttes on BLM
lands (Jennifer Wheeler, botanist, BLM, Arcata Resource Area, pers.
comm., 1997).
Previous Federal Action
Federal government action on this species began on December 15,
1980 (45 FR 82480), when the Service published a revised Notice of
Review of native plant taxa considered for listing under the Act.
Thlaspi californicum (then known as T. californicum var. montanum) was
included as a category 2 candidate. Category 2 candidates were formerly
defined as taxa for which data on biological vulnerablilty and threats
in the Service's possession indicated that listing was possibly
appropriate, but was not sufficient to support proposed rules. The
taxon remained a category 2 candidate in the revised plant notices of
review published in the Federal Register on November 28, 1983 (48 FR
53640), and September 27, 1985 (50 FR 39526). The plant was listed as a
category 1 candidate in the February 21, 1990 (55 FR 6184), and
September 30, 1993 (58 FR 51144), revised notices of review. Category 1
candidates were defined as those taxa for which the Service had on file
sufficient information on biological vulnerability and threats to
support the preparation of listing proposals, but issuance of the
proposed rule was precluded by other pending listing proposals of
higher priority. 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 candidates. Thlaspi californicum was listed
as a candidate in that notice of review. This species has been given a
listing priority assignment number of 2, due to the high magnitude,
imminent threats to its continued existence.
The processing of this proposed rule conforms with the Service's
final listing priority guidance for fiscal year 1997, published in the
Federal Register on December 5, 1996 (61 FR 64475). In a Federal
Register notice published on October 23, 1997 (62 FR 55628), the
guidance was extended beyond fiscal year 1997 until such time as the
fiscal year 1998 appropriations bill for the Department of the Interior
becomes law and new final guidance is published. The fiscal year 1997
guidance clarifies the order in which the Service will process
rulemakings following two related events: (1) the lifting on April 26,
1996, of the moratorium on final listings imposed on April 10, 1995
(Public Law 104-6), and (2) the restoration of significant funding for
listing through passage of the Omnibus Budget Reconciliation Act on
April 26, 1996, following severe funding constraints imposed by a
number of continuing resolutions between November 1995 and April 1996.
Based on biological considerations, this guidance establishes a
``multi-tiered approach that assigns relative priorities, on a
descending basis, to actions to be carried out under section 4 of the
Act'' (61 FR 64479). The guidance calls for giving highest priority to
handling emergency situations (Tier 1) and second highest priority
(Tier 2) to resolving the listing status of the outstanding proposed
listings. Tier 3 includes the processing of new proposed listings for
species facing high magnitude threats. This proposed rule for Thlaspi
californicum falls under Tier 3. The guidance states that ``effective
April 1, 1997, the Service will concurrently undertake all of the
activities presently included in Tiers 1, 2, and 3'' (61 FR 64480). The
Service has thus begun implementing a more balanced listing program,
including processing more Tier 3 activities. The completion of this
Tier 3 activity (a proposal for a species with high-magnitude, imminent
threats) follows those guidelines.
Summary of Factors Affecting the Species
Section 4 of the Act and regulations (50 CFR part 424) promulgated
to implement the listing provisions of the Act set forth the procedures
for adding species to the Federal lists. A species may be determined to
be endangered or threatened due to one or more of the five factors
described in section 4(a)(1). These factors and their application to
Thlaspi californicum S. Watson (Kneeland Prairie penny-cress) are as
follows:
A. The Present or Threatened Destruction, Modification, or Curtailment
of its Habitat or Range.
The habitat of Thlaspi californicum has been significantly reduced
within the past 33 years. Just prior to 1964, an estimated 2.0 to 2.25
ha (5 to 6 ac) of habitat existed at Kneeland Prairie (Meyers 1991).
Approximately 60 to 70 percent of the habitat at Kneeland Prairie has
been lost since 1964, due to construction of the Kneeland Airport,
realignment of the county road that runs through Kneeland Prairie, and
construction of the California Department of Forestry (CDFFP) helitack
base (Meyers 1991; Imper 1990; Imper, pers. comm., 1997). Additional
habitat and plants are currently threatened by the proposed expansion
[[Page 7114]]
of the Kneeland Prairie Airport and potential road realignment.
The Kneeland Prairie Airport serves principally as the backup
airport for Rohnerville, Murray, Eureka Municipal, and Arcata-Eureka
airports. Small single-engine and occasionally twin-engine planes use
Kneeland Airport. This airfield is especially important when airports
at lower elevations are fogged in, a frequent occurrence in the region
(Hodges & Shutt 1993). Kneeland Prairie is the only airport in the
Humboldt Bay area that can be used when the bay is fogged in (Don
Tuttle, Resource Specialist, Humboldt County Public Works, pers. comm.,
1997). The airport is particularly important for commercial express
mail and air freight carriers, as well as other couriers (Ray Beeninga,
Airports Manager, Humboldt County, pers. comm., 1997).
Humboldt County contracted a study to evaluate its airports and
prepare appropriate planning documents (Hodges & Shutt 1993). The study
provided an assessment of Kneeland Airport's role and associated
airfield requirements. The report also discussed land use compatibility
issues and descriptions of capital projects, and provided documentation
required to upgrade Kneeland Airport from temporary to permanent
inclusion in the National Plan for Integrated Airport Systems. That
designation allows the county to receive Federal funding for airport
modifications through the Federal Aviation Administration (FAA).
Recommendations in the report included development of a complete
geotechnical study of specific engineering designs to stabilize the
airport, and construction of a new parking area meeting FAA setback
standards. The report discussed design constraints for placement of the
new parking area. The location of the CDFFP helitack base limits the
ability of the airport to expand the existing parking area to the
northwest (Hodges & Shutt 1993). The recommended location for the new
parking area is on the eastern side of the airport (Hodges & Shutt
1993), adjacent to the eastern colony of Thlaspi californicum.
Construction of the parking facility at Kneeland Airport could
adversely affect the habitat and individuals of the eastern colony due
to the proximity of the plants to the potential site.
Humboldt County is also contracting an initial study to evaluate
the geotechnical feasibility and cost of modifying Kneeland Prairie
Airport. The study, currently in progress (D. Tuttle and D. Imper,
pers. comms., 1997), is evaluating ways to solve problems involving
subsidence of the runway, slope stabilization, and the safety issue
that the runway is too short (Dave Dietz, Project Manager, Shutt-Moen
Associates, pers. comm., 1997). Possible options include leaving the
airport configuration as is (i.e., repairing current subsidence, but
not extending the runway), finding a different site for a new airport,
or modifying the existing airport (D. Dietz, pers. comm., 1997).
Financial constraints could influence the choice among the
alternatives. In additional, exploratory soil boring is needed to
determine how to stabilize the airport and to determine the cost of
extending the runway. Thlaspi californicum occurs on the slopes
immediately adjacent to the airfield. Exploratory boring may affect
individuals located immediately adjacent to airport lands. Modification
of the existing airport is anticipated to occur in the year 2000 (R.
Beeninga, pers. comm., 1997).
The realignment of the county road adjacent to the airport could
affect the western occurrence of Thlaspi californicum at Kneeland
Prairie (D. Imper, pers. comm., 1997). The road currently runs along
the southwest edge of the runway and serves areas beyond the airport.
The aviation manager would not be authorized to modify the road except
as necessary for slope stabilization or as the result of possible
runway extension at the south end of the airport. The extension of the
runway to the south is not expected to directly impact T. californicum.
However, if the runway is extended 30 to 65 m (90 to 200 ft) (R.
Beeninga, pers. comm., 1997), the runway will run through the current
road. The road would then either need to go under the runway via a
tunnel, or be realigned. Road realignment could result in impacts to
the habitat and individual plants. The western colony of Thlaspi
californicum occurs just downslope of the current road. For safety
reasons, it is likely that Humboldt County will undertake straightening
and/or widening the road, either independent of or concurrent with
runway expansion (L. Host, in litt., 1997). The road adjacent to the
airport is narrow; a blind, 90-degree curve in the road around the end
of the runway limits safe speeds to only 10 to 15 miles per hour. These
conditions could warrant a county decision to realign the road in order
to achieve a safer curve radius at the end of the runway. Unless the
approach to that portion of the road is moved outward beyond the plants
(which would require extra length and expense), the realignment would
cross the remaining serpentine habitat and eliminate about half of the
remaining plants in the western colony. The Service anticipates that
such roadwork would occur during airport construction in order to avoid
the expense of bringing necessary machinery to the site twice.
B. Overutilization for Commercial, Recreational, Scientific, or
Educational Purposes
Overutilization is not known to be a threat for this plant.
C. Disease or Predation
There is no known threat to Thlaspi californicum from disease.
Cattle grazing occurs throughout the prairie and the area surrounding
the airport (Imper 1997). Cattle trails run through T. californicum
habitat (Meyers 1991), but there does not appear to be any threat to
the species from current levels of grazing.
D. The Inadequacy of Existing Regulatory Mechanisms
The California Environmental Quality Act (CEQA) (chapter 2, section
21050 et seq. of the California Public Resources Code) requires full
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 the other
agencies concerned with the 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.'' Species that are eligible
for listing as rare, threatened, or endangered but are not so listed
are given the same protection as those species that are officially
listed with the State or Federal governments. Once significant effects
are identified, the lead agency has the option of requiring mitigation
for effects through changes in the project or to decide that overriding
considerations 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 dependent upon the discretion of the agency involved.
When the CDFFP constructed the Kneeland Helitack Base in 1980, a
botanical assessment was required by the Humboldt County Planning
Department for issuance of a conditional use permit. However, CDFFP did
not include any analysis of potential impacts to Thlaspi californicum,
although records of its California Native
[[Page 7115]]
Plant Society 1B status and CNDDB documentation of the species'
presence were available at that time (Imper 1990, Meyers 1991).
E. Other Natural or Manmade Factors Affecting Its Continued Existence
Thlaspi californicum has never been found anywhere other than at
Kneeland Prairie, where the single population occupies 0.25 ha (0.6
ac), bisected by the Kneeland Airport. This plant occupies serpentine
prairie habitat that is quite restricted in extent. The combination of
a single population and restricted habitat makes T. californicum
susceptible to destruction of all or a significant portion of its range
from naturally occurring events such as fire, drought, or severe
erosion (Shaffer 1981, Primack 1993). Chance events causing population
fluctuations or even population extirpations are not usually a concern
until the number of individuals or geographic distribution becomes as
limited as with T. californicum (Primack 1993). The single known
locality of the species makes the population at Kneeland Prairie
particularly susceptible to extinction due to fire or an erosional
event causing slope failure. Even one such event has the potential to
seriously impact the sole population of the species.
The Service has carefully assessed the best scientific and
commercial information available regarding the past, present, and
future threats faced by this species in determining to propose this
rule. Airport expansion activities, potential road realignment,
inadequate regulatory mechanisms, and naturally occurring events such
as fire imperil the continued existence of this plant. The one known
population of Thlaspi californicum includes approximately 11,000
individual plants scattered within a 0.25 ha (0.6 ac) area. The species
is in danger of extinction throughout all of its known range. Based on
this evaluation, the preferred action is to list T. californicum as
endangered. Other alternatives to this action were considered but not
preferred because they would not provide adequate protection and would
not be consistent with the Act. Listing T. californicum as endangered
would provide additional protection and is consistent with the Act's
definition of endangered. Critical habitat is not being proposed for T.
californicum for reasons discussed in the ``Critical Habitat'' section
of this proposal.
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 features (I) essential to the conservation
of the species and (II) that may require special management
consideration or protection and; (ii) specific areas outside the
geographical area occupied by a species at the time it is listed, upon
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
a species is determined to be endangered or threatened. The Service
finds that designation of critical habitat is not prudent for Thlaspi
californicum. 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.
The Service determines that designation of critical habitat for
Thlaspi californicum is not prudent due to lack of benefit to the
species. Critical habitat designation provides protection only on
Federal lands or on private lands when there is Federal involvement
through authorization or funding of, or participation in, a project or
activity. Although this plant occurs only on private land, it may be
affected by projects with Federal connections, including potential
Federal funding of the county road realignment and airport expansion by
the Federal Highway Administration and the FAA respectively. Section
7(a)(2) of the Act requires Federal agencies, in consultation with the
Service, to ensure that any action authorized, funded, or carried out
by such agency is not likely to jeopardize the continued existence of a
federally listed species, or to destroy or adversely modify designated
critical habitat.
Thlaspi californicum has an extremely narrow distribution in a
serpentine prairie, totalling about 0.25 ha (0.6 ac) in two parcels
separated by the runway of Kneeland Airport, whose construction appears
to have destroyed most of the plant's habitat. At the present time, no
other site is known to be occupied by or suitable for this plant. The
private landowners at Kneeland are aware of the plant's presence and
extremely limited habitat, as are the airport operators and others
involved in management of the area. Therefore, designation of critical
habitat would provide no benefit with respect to notification. In
addition, given the species' narrow distribution and precarious status,
virtually any conceivable adverse effect would very likely jeopardize
its continued existence. Designation of critical habitat for T.
californicum would therefore provide no benefit to the species apart
from the protection afforded by listing the plant as endangered.
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 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
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 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 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.
All of the occurrences of Thlaspi californicum are on privately
owned
[[Page 7116]]
land. However, impacts of modifying the adjacent airport have the
potential to adversely affect T. californicum, due to the proximity of
the plants to the proposed parking apron. Funds from the FAA have been
used to partially finance a planning document for the Kneeland Airport
and are proposed to be used for airport modifications. Private sector
funding is not anticipated to be available for Kneeland Airport (Hodges
& Shutt 1993). Realignment of a county road adjacent to the airport may
be required if the runway is extended. This work could be partially
funded by Federal Highway Administration grants, thereby providing
another avenue for section 7 consultation.
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 for endangered plants, apply. These prohibitions, in part,
make it illegal for any person subject to the jurisdiction of the
United States to import or export an endangered plant, transport such a
plant in interstate or foreign commerce in the course of a commercial
activity, sell or offer for sale an endangered plant in interstate or
foreign commerce, or remove and reduce an endangered plant to
possession from areas under Federal jurisdiction. In addition, for
plants listed as endangered, the Act prohibits 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 those activities that would or would not constitute a
violation of section 9 of the Act if a species is listed. The intent of
this policy is to increase public awareness of the effect of a proposed
listing on proposed and ongoing activities within a species' range.
This species is not located on areas under Federal jurisdiction.
Collection, damage or destruction of this 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 areas not under Federal jurisdiction
would constitute a violation of section 9 if conducted in knowing
violation of California State law or regulations, or in violation of
State criminal trespass law. Moderate livestock grazing and normal use
of the existing airfield and road are among the activities that would
be unlikely to violate section 9. Questions regarding whether specific
activities would constitute a violation of section 9, should this
species be listed, should be directed to the Field Supervisor of the
Sacramento Field Office (see ADDRESSES section).
The Act and 50 CFR 17.62 and 17.63 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. It is anticipated that few trade permits would
ever be sought or issued for Thlaspi californicum because it is not
common in cultivation or in the wild. Requests for copies of the
regulations regarding listed species and inquiries regarding
prohibitions and permits may be addressed to the U.S. Fish and Wildlife
Service, Endangered Species Permits, 911 N.E. 11th Avenue, Portland,
Oregon 97232-4181 (phone 503/231-2063; facsimile 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. The Service
will follow its peer review policy (59 FR 34270; July 1, 1994) in the
processing of this rule. Comments are particularly sought concerning:
(1) Biological, commercial trade, or other relevant data concerning
any threat (or lack thereof) to Thlaspi californicum;
(2) The location of any additional populations of this species and
the reasons why any habitat should or should not be determined to be
critical habitat as provided by section 4 of the Act;
(3) Additional information concerning the range, distribution, and
population size of this species; and
(4) Current or planned activities in the subject area and their
possible impacts on this species.
A final determination of whether to list this species will take
into consideration the comments and any additional information received
