DEPARTMENT OF THE INTERIOR

Fish and Wildlife Service


Endangered and Threatened Wildlife and Plants; Initiation of 5-
Year Reviews of 58 Species in California and Nevada; Availability of 
Completed 5-Year Reviews in California and Nevada

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Notice of initiation of 5-year reviews; availability of 
completed 5-year reviews.

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

SUMMARY: We, the U.S. Fish and Wildlife Service, announce the 
initiation of a 5-year review of 58 species under section 4(c)(2)(B) of 
the Endangered Species Act (Act). The purpose of a 5-year review is to 
ensure that the classification of a species as threatened or endangered 
on the List of Endangered and Threatened Wildlife and Plants is 
accurate and based on the best scientific and commercial data available 
at the time of the review. We are requesting submission of any such 
information that has become available since the original listing of 
each of these 58 species. Based on the results of these 5-year reviews, 
we will make the requisite findings under section 4(c)(2)(A) of the 
Act. We also indicate in this notice the 5-year reviews we completed 
for species in California and Nevada in FY 2006.

DATES: We must receive your information no later than April 16, 2007. 
However, we will continue to accept new information about any listed 
species at any time.

ADDRESSES: See SUPPLEMENTARY INFORMATION for instructions on how to 
submit information and review the information that we receive on these 
species.

FOR FURTHER INFORMATION CONTACT: For species-specific information, 
contact the appropriate individual listed under ``Public Solicitation 
of New Information.'' For contact information about completed 5-year 
reviews, see ``Completed 5-Year Reviews.''

SUPPLEMENTARY INFORMATION:

Background

Why Do We Conduct a 5-Year Review?

    Under the Endangered Species Act (Act) (16 U.S.C. 1531 et seq.), we 
maintain a List of Endangered and Threatened Wildlife and Plants at 50 
CFR 17.11 (for animals) and 17.12 (for plants). Section 4(c)(2)(A) of 
the Act requires that we conduct a review of listed species at least 
once every 5 years. Then, on the basis of such reviews under section 
4(c)(2)(B), we determine whether or not any species should be removed 
from the List (delisted), or reclassified from endangered to threatened 
or from threatened to endangered. Delisting a species must be supported 
by the best scientific and commercial data available and only 
considered if such data substantiates that the species is neither 
endangered nor threatened for one or more of the following reasons: (1) 
The species is considered extinct; (2) the species is considered to be 
recovered; and/or (3) the original data available when the species was 
listed, or the interpretation of such data, were in error. Any change 
in Federal classification would require a separate rulemaking process. 
The regulations in 50 CFR 424.21 require that we publish a notice in 
the Federal Register announcing those species currently under active 
review. This notice announces our active review of the 58 species 
listed in Table 1.

What Information Do We Consider in the Review?

    A 5-year review considers all new information available at the time 
of the review. In conducting these reviews, we consider the best 
scientific and commercial data that has become available since the 
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 ``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.

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.
    Our assessment of these factors is required, under section 4(b)(1) 
of the Act, to be based solely on the best scientific and commercial 
data available.

What Could Happen as a Result of Our Review?

    If we find information concerning the 58 species listed in Table 1 
indicating that 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; (b) reclassify the species 
from endangered to threatened; or (c) remove the species from the List. 
If we find that a change in classification is not warranted, the 
species will remain on the List under its current status.

Public Solicitation of New Information

    To ensure that these 5-year reviews are complete and based on the 
best available scientific and commercial information, we solicit new 
information from the public, concerned governmental agencies, Tribes,

Completed 5-Year Reviews

    We also take this opportunity to inform the public of 12 5-year 
reviews that we completed in FY 2006 for species in California and 
Nevada. These 12 reviews can be found at http://www.fws.gov/cno/es/
5yr.html. Any recommended change in listing status will require a 
separate rulemaking process. The table below summarizes the results of 
these reviews:
