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


We, the U.S. Fish and Wildlife Service, are initiating 5-year reviews for 34 species under the Endangered Species Act of 1973, as amended (Act). We request any new information on these species that may have a bearing on their classification as endangered or threatened. Based on the results of these 5-year reviews, we will make a finding on whether these species are properly classified under the Act. We also announce in this notice 96 completed 5-year reviews for species in California and Nevada in Fiscal Year (FY) 2009 and early (FY) 2010.


To allow us adequate time to conduct these reviews, we must receive your information no later than July 20, 2010. However, we will continue to accept new information about any listed species at any time.


For instructions on how to submit information and review the information that we receive on these species, see “Request for New Information.”

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) (List). We amend the List by publishing final rules in the Federal Register. Section 4(c)(2)(A) of the Act requires that we conduct a review of listed species at least once every 5 years. Section 4(c)(2)(B) requires that we determine (1) Whether a species no longer meets the definition of threatened or endangered and should be removed from the List (delisted); (2) whether a species listed as endangered more properly meets the definition of threatened and should be reclassified to threatened; or (3) whether a species listed as threatened more properly meets the definition of endangered and should be reclassified to endangered. Using the best scientific and commercial data available, we will consider a species for delisting if the data substantiate 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 requires a separate rulemaking process. We are requesting submission of any new information (best scientific and commercial data) on these species since they were originally listed or since the species' most recent status review.

Our regulations in the Code of Federal Regulations (CFR) at 50 CFR 424.21 require that we publish a notice in the Federal Register announcing those species currently under review. This notice announces initiation of our active review of 34 species in California, and Nevada (Table 1).

What information do we consider in the review?

In our 5-year review, we consider 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 the 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 the five factors under the 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.

Request for New Information

We request any new information concerning the status of these wildlife and plant species. 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 gather and analyze the data, and/or copies of any pertinent publications, reports, or letters by knowledgeable sources. We specifically request information regarding data from any Start Printed Page 28638systematic 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 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.

Our practice is to make information, including names and home addresses of respondents, available for public review. Before including your address, telephone number, e-mail address, or other personal identifying information in your response, you should be aware that your entire submission—including your personal identifying information—may be made publicly available at any time.

How are these species currently listed?

The current listing status of each species for which we are initiating 5-year reviews in this notice is in Table 1 above. The current status may also be found on the List, which covers all endangered and threatened species, and which is available on our Internet site at​wildlife.html#Species.


To help you submit information about the species we are reviewing, we provide the following definitions:

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.

Endangered species means any species that is in danger of extinction throughout all or a significant portion of its range.

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.

Experimental population means any population (including any offspring arising solely therefrom) authorized by the Secretary of the Interior for release outside the current range of nonexperimental populations of the same species, but only when, and at such times as, the population is wholly separate geographically from nonexperimental populations of the same species. Each member of a nonessential experimental population shall be treated, except when it occurs in an area within the National Wildlife Refuge System or the National Park System, as a species proposed to be listed under section 4 of the Endangered Species Act.

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 Start Printed Page 28639existing regulatory mechanisms; or (E) Other natural or manmade factors affecting its continued existence. Section 4(b)(1)(A) 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 the species will remain on the List under its current status.

Completed 5-Year Reviews

We also take this opportunity to inform the public of 96 5-year reviews that we completed in FY 2009 and early FY 2010 for species in California and Nevada (Table 2). These 96 reviews can be found at​cno/​es/​5yr.html. Any recommended change in listing status resulting from these completed reviews will require a separate rulemaking process.
