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
