[FWS-R2-ES-2008-N0023, 21012-11130000-C4]
Endangered and Threatened Wildlife and Plants; 5-Year Reviews of
28 Southwestern Species
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of reviews.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce 5-
year reviews of 28 southwestern species listed under the Endangered
Species Act of 1973 (Act). The purpose of reviews conducted under this
section of the Act is to ensure that the classification of species as
threatened or endangered on the List of Endangered and Threatened
Wildlife and Plants is accurate. The 5-year review is an assessment of
the best scientific and commercial data available at the time of the
review.
DATES: To allow adequate time to conduct this review, information
submitted for our consideration must be received on or before June 18,
2008. However, we will continue to accept new information about any
listed species at any time.
ADDRESSES: Information submitted on these species should be sent to the
Service at the addresses listed under ``Public Comments'' in the
SUPPLEMENTARY INFORMATION section. Information received in response to
this notice of review will be available for public inspection by
appointment, during normal business hours, at the same addresses.
FOR FURTHER INFORMATION CONTACT: Contact the appropriate office named
in ``Public Comments'' for species-specific information.
SUPPLEMENTARY INFORMATION:
Why is a 5-year review conducted?
Section 4(c)(2)(A) of the Act (16 U.S.C. 1531 et seq.) requires
that we conduct a review of listed species at least once every 5 years.
We are then, under section 4(c)(2)(B) and the provisions of subsections
(a) and (b), to determine, on the basis of such a review, whether or
not any species should be removed (delisted) from the List of
Endangered and Threatened Wildlife and Plants (50 CFR 17.12), or
reclassified from endangered to threatened (downlisted), or from
threatened to endangered (uplisted).
The 5-year review is an assessment of the best scientific and
commercial data available at the time of the review. Therefore, we are
requesting submission of any new information (best scientific and
commercial data) on the following 28 species since their original
listings as either endangered (Arizona hedgehog cactus, Big Bend
gambusia, Brady pincushion cactus, Clear Creek gambusia, Comal Springs
dryopid beetle, Comal Springs riffle beetle, fountain darter, Kearney
blue star, Leon Springs pupfish, Peck's Cave amphipod, San Marcos
gambusia, Sonoran pronghorn, Socorro isopod, Socorro springsnail, south
Texas ambrosia, southwestern willow flycatcher, Terlingua Creek cat's-
eye, Texas ayenia, Texas blind salamander, Texas wild-rice, Tobusch
fishhook cactus, Yaqui chub, and Yaqui topminnow) or threatened
(beautiful shiner, Hinckley oak, San Marcos salamander, Sonora chub,
and Yaqui catfish). If the present classification of any of these
species is not consistent with the best scientific and commercial
information available, the Service will recommend whether or not a
change is warranted in the Federal classification of that species. Any
change in Federal classification would require a separate rule-making
process.
Our regulations at 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 28 species
listed in Table 1.
What information is considered in the review?
A 5-year review considers all new information available at the time
of the review. These reviews will consider the best scientific and
commercial data that has become available since the current listing
determination or most recent status review of each species, 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 to 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 of Endangered and
Threatened Wildlife and Plants, and improved analytical methods.
How are these species currently listed?
The List of Endangered and Threatened Wildlife and Plants (List) is
found in 50 CFR 17.11 (wildlife) and 17.12 (plants). Amendments to the
List through final rules are published in the Federal Register. The
List is also available on our Internet site at http://www.fws.gov/
endangered/wildlife.html. In Table 1 below, we provide a summary of the
listing information for the species under active review.

Definitions Related to This Notice
The following definitions are provided to assist those persons who
contemplate submitting information regarding the species being
reviewed:
A. Species includes any species or subspecies of fish, wildlife, or
plant, and any distinct population segment of any species of
vertebrate, which interbreeds when mature.
B. Endangered means any species that is in danger of extinction
throughout all or a significant portion of its range.
C. Threatened means any species that is likely to become an
endangered species within the foreseeable future throughout all or a
significant portion of its range.
How do we determine whether a species is endangered or threatened?
Section 4(a)(1) of the Act establishes 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.
Section 4(a)(1) of the Act requires that our determination be made
on the basis of the best scientific and commercial data available.
What could happen as a result of this review?
If we find that there is new information concerning any of the 28
species listed in Table 1 indicating 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 endangered to threatened;
(b) reclassify the species from threatened to endangered; or (c) remove
the species from the List. If we determine that a change in
classification is not warranted, then these species will remain on the
List under their current status.
