Endangered and Threatened Wildlife and Plants; 5-Year Reviews of Species in California, Nevada, and the Klamath Basin of Oregon

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.

SUPPLEMENTARY INFORMATION: Back to Top

I. Why do we conduct 5-year reviews? Back to Top

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.

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? Back to Top

III. What information do we consider in our review? Back to Top

We consider all new information available at the time we conduct a 5-year status review. We consider the best scientific and commercial data that has become available since our 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 “IV., 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.

We specifically request information regarding data from any systematic 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.

IV. How do we determine whether a species is endangered or threatened? Back to Top

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.

Under section 4(b)(1) of the Act, we must base our assessment of these factors solely on the best scientific and commercial data available.

V. What could happen as a result of our review? Back to Top

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 remains on the List under its current status.

VI. Request for New Information Back to Top

To ensure that a 5-year review is complete and based on the best available scientific and commercial information, we request new information from all sources. See “III., 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.

Submit your comments and materials to the appropriate Fish and Wildlife Office listed under “VIII., Contacts.”
