Fish and Wildlife Service

Endangered and Threatened Wildlife and Plants; Initiation of 5-
Year Reviews of Seven Wildlife Species and Two Plant Species in the 
Mountain-Prairie Region

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Notice of review; request for comments.


SUMMARY: We, the U.S. Fish and Wildlife Service (Service), initiate 5-
year reviews of seven wildlife species--Canada lynx (Lynx canadensis), 
grizzly bear (Ursus arctos horribilis) (as listed in the lower 48-
States excluding the Greater Yellowstone Area population; see table 1), 
bonytail chub (=bonytail) (Gila elegans), humpback chub (Gila cypha), 
Colorado pikeminnow (=squawfish) (Ptychocheilus lucius), razorback 
sucker (Xyrauchen texanus), and Uncompahgre fritillary butterfly 
(Boloria acrocnema); and two plant species--Howellia aquatilis (water 
howellia) and Astragalus desereticus (Deseret milk-vetch)--in the 
Mountain-Prairie Region under the Endangered Species Act of 1973, as 
amended (Act). We conduct 5-year reviews to ensure that our 
classification of each species as threatened or endangered on the List 
of Endangered and Threatened Wildlife and Plants is accurate. A 5-year 
review is an assessment of the best scientific and commercial data 
available at the time of the review.

DATES: To allow us adequate time to conduct our review, we must receive 
your information no later than June 18, 2007. However, we will continue 
to accept new information about any listed species at any time.

ADDRESSES: For instructions on how to submit information and review the

[[Page 19550]]

information that we receive on these species, see ``Public Solicitation 
of New Information.''

FOR FURTHER INFORMATION CONTACT: For species-specific information, 
contact the appropriate person under ``Public Solicitation of New 


Why Do We Conduct a 5-Year Review?

    Section 4(c)(2)(A) of the Act 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 from the List of Endangered and Threatened Wildlife and Plants 
(delisted), or reclassified from endangered to threatened (downlisted), 
or reclassified 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 these species since they were originally listed.
    For each species, if its present classification is not consistent 
with the best scientific and commercial information available, we will 
recommend whether or not a change is warranted in the Federal 
classification of the species. Any change in Federal classification 
would require a separate rulemaking 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 species in Table

What Information Do We Consider in Our Review?

    In our 5-year review, we consider all new information available at 
the time of the review. These reviews will consider the best scientific 
and commercial data that have become available since the original 
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 

Public Solicitation of New Information

    We request any new information concerning the status of the 
wildlife species Canada lynx, grizzly bear, bonytail chub, humpback 
chub, Colorado pikeminnow, razorback sucker, and Uncompahgre fritillary 
butterfly, and of the plant species Howellia aquatilis and Astragalus 
desereticus. See ``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

How Are These Species Currently Listed?

    Table 1 gives current listing information. Also, the List of 
Endangered and Threatened Wildlife and Plants (List), which covers all 
listed species, is in 50 CFR 17.11 (wildlife) and 17.12 (plants). We 
amend the List by publishing final rules in the Federal Register. The 
List also is available on our Internet site at http://endangered.fws.gov/wildlife.html#Species


    To help you submit information about the species being reviewed, we 
provide the following definitions:
    (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; and
    (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 
    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 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 this species will remain on the List under its current status.


    This document is published under the authority of the Endangered 
Species Act of 1973, as amended (16 U.S.C. 1531 et seq.).
