Endangered and Threatened Wildlife and Plants; 5-Year Reviews of 
Species in California, Nevada, and the Klamath Basin of Oregon

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: We, the U.S. Fish and Wildlife Service, are initiating 5-year 
reviews for 53 species under the Endangered Species Act of 1973, as 
amended (Act). We conduct these reviews to ensure that our 
classification of each species on the Lists of Endangered and 
Threatened Wildlife and Plants as threatened or endangered is accurate. 
A 5-year review assesses the best scientific and commercial data 
available at the time of the review. We are requesting any information 
that has become available since our original listing of each of these 
species. Based on review results, we will determine whether we should 
change the listing status of any of these species. In this notice, we 
also announce 5-year reviews that were completed for 32 species in 
California and Nevada between April 1, 2010, and March 16, 2011.

DATES: To ensure consideration, please send your written information by 
July 25, 2011.

ADDRESSES: For how and where to send comments or information, see 
``VIII., Contacts.''

FOR FURTHER INFORMATION CONTACT: For species-specific information, 
contact the appropriate person listed under VIII., Contacts.'' For 
contact information about completed 5-year reviews, see '' IX., 
Completed 5-Year Reviews.'' Individuals who are hearing-impaired or 
speech-impaired may call the Federal Relay Service at (800) 877-8337 
for TTY assistance.

SUPPLEMENTARY INFORMATION:

I. Why do we conduct 5-year reviews?

    Under the Act (16 U.S.C. 1531 et seq.), we maintain Lists of 
Endangered and Threatened Wildlife and Plants (which we collectively 
refer to as the List) in the Code of Federal Regulations (CFR) at 50 
CFR 17.11 (for animals) and 17.12 (for plants). Section 4(c)(2)(A) of 
the Act requires us to review each listed species' status at least once 
every 5 years. Then, under section 4(c)(2)(B), we determine whether to 
remove any species from the List (delist), to reclassify it from 
endangered to threatened, or to reclassify it from threatened to 
endangered. Any change in Federal classification requires a separate 
rulemaking process.
    In classifying, we use the following definitions, from 50 CFR 
424.02:
    (A) Species includes any species or subspecies of fish, wildlife, 
or plant, and any distinct population segment of any species of 
vertebrate, that interbreeds when mature;
    (B) Endangered species means any species that is in danger of 
extinction throughout all or a significant portion of its range; and
    (C) Threatened species means any species that is likely to become 
an endangered species within the foreseeable future throughout all or a 
significant portion of its range.
    We must support delisting by the best scientific and commercial 
data available, and only consider delisting if data substantiate that 
the species is neither endangered nor threatened for one or more of the 
following reasons (50 CFR 424.11(d)):
    (A) The species is considered extinct;
    (B) The species is considered to be recovered; or
    (C) The original data available when the species was listed, or the 
interpretation of data, were in error.

[[Page 30378]]

    Our regulations at 50 CFR 424.21 require that we publish a notice 
in the Federal Register announcing the species we are reviewing.

II. What species are under review?

    This notice announces our active 5-year status reviews of the

III. What information do we consider in our review?

    We consider all new information available at the time we conduct a 
5-year status review. We consider the best scientific and commercial 
data that has become available since our current listing determination 
or most recent status review, such as:
    (A) Species biology, including but not limited to population 
trends, distribution, abundance, demographics, and genetics;
    (B) Habitat conditions, including but not limited to amount, 
distribution, and suitability;
    (C) Conservation measures that have been implemented that benefit 
the species;
    (D) Threat status and trends (see five factors under heading ``IV., 
How Do We Determine Whether a Species Is Endangered or Threatened?''); 
and
    (E) Other new information, data, or corrections, including but not 
limited to taxonomic or nomenclatural changes, identification of 
erroneous information contained in the List, and improved analytical 
methods.
    We specifically request information regarding data from any 
systematic surveys, as well as any studies or analysis of data that may 
show population size or trends; information pertaining to the biology 
or ecology of these species; information regarding the effects of 
current land management on population distribution and abundance; 
information on the current condition of habitat; and recent information 
regarding conservation measures that have been implemented to benefit 
the species. Additionally, we specifically request information 
regarding the current distribution of populations and

[[Page 30380]]

evaluation of threats faced by the species in relation to the five 
listing factors (as defined in section 4(a)(1) of the Act) and the 
species' listed status as judged against the definition of threatened 
or endangered. Finally, we request recommendations pertaining to the 
development of, or potential updates to, recovery plans and additional 
actions or studies that would benefit these species in the future.

IV. How do we determine whether a species is endangered or threatened?

    Section 4(a)(1) of the Act requires that we determine whether a 
species is endangered or threatened based on one or more of the five 
following factors:
    (A) The present or threatened destruction, modification, or 
curtailment of its habitat or range;
    (B) Overutilization for commercial, recreational, scientific, or 
educational purposes;
    (C) Disease or predation;
    (D) The inadequacy of existing regulatory mechanisms; or
    (E) Other natural or manmade factors affecting its continued 
existence.
    Under section 4(b)(1) of the Act, we must base our assessment of 
these factors solely on the best scientific and commercial data 
available.

V. What could happen as a result of our review?

    For each species under review, if we find new information that 
indicates a change in classification may be warranted, we may propose a 
new rule that could do one of the following:
    (A) Reclassify the species from threatened to endangered (uplist);
    (B) Reclassify the species from endangered to threatened 
(downlist); or
    (C) Remove the species from the List (delist).
    If we determine that a change in classification is not warranted, 
then the species remains on the List under its current status.

VI. Request for New Information

    To ensure that a 5-year review is complete and based on the best 
available scientific and commercial information, we request new 
information from all sources. See ``III., What Information Do We 
Consider in Our Review?'' for specific criteria. If you submit 
information, support it with documentation such as maps, bibliographic 
references, methods used to gather and analyze the data, and/or copies 
of any pertinent publications, reports, or letters by knowledgeable 
sources.
    Submit your comments and materials to the appropriate Fish and 
Wildlife Office listed under ``VIII., Contacts.''

IX. Completed 5-Year Reviews

    We also take this opportunity to inform the public of 5-year 
reviews that we completed between April 1, 2010, and March 16, 2011, 
for 31 species in California and Nevada (Table 2). In addition, we 
include in Table 2 the desert pupfish for which a review was completed 
in which we concurred. Reviews for these 32 species can be found at

change in listing status resulting from these completed reviews will 
require a separate rulemaking process.
