Start Preamble


Fish and Wildlife Service, Interior.




The U.S. Fish and Wildlife Service (Service) announces a 5-year review of greenback cutthroat trout (Oncorhynchus clarki stomias) under the Endangered Species Act of 1973 (ESA). A 5-year review is a periodic process conducted to ensure that the listing classification of a species is accurate. A 5-year review is based on the best scientific and commercial data available at the time of the review; therefore, we are requesting submission of any such information on greenback cutthroat trout that has become available since its reclassification as a threatened species in 1978. Based on the results of this 5-year review, we will make the requisite finding under the ESA.


To allow us adequate time to conduct this review, we must receive your information no later than February 13, 2006. However, we will continue to accept new information about any listed species at any time.


Submit information to Susan Linner, Field Supervisor, Colorado Field Office, U.S. Fish and Wildlife Service, 755 Parfet Street, Suite 361, Lakewood, Colorado 80215. Information received in response to this notice and review, as well as other documentation in our files, will be available for public inspection, by appointment, during normal business hours, at the above address.

Under the ESA (16 U.S.C. 1531 et seq.), the Service maintains a list of endangered and threatened wildlife and plant species at 50 CFR 17.11 (for animals) and 17.12 (for plants). Section 4(c)(2)(A) of the ESA requires that we conduct a review of listed species at least once every 5 years. Based on such reviews, under section 4(c)(2)(B), we then determine whether or not any species should be removed from the List (delisted), or reclassified from endangered to threatened or from threatened to endangered. Delisting a species must be supported by the best scientific and commercial data available and is only considered if these 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 would require a separate rulemaking process. The regulations in 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 greenback cutthroat trout currently listed as threatened. We request submission of any new information on the greenback cutthroat trout that has become available since since its reclassification as a threatened species in 1978 (43 FR 16343, April 18, 1978).

Public Solicitation of New Information

To ensure that the 5-year review is complete and based on the best available scientific and commercial information, we are soliciting new information from the public, concerned governmental agencies, tribes, the scientific community, industry, Start Printed Page 74031environmental entities, and any other interested parties concerning the status of the greenback cutthroat trout.

The 5-year review considers the best scientific and commercial data and all new information that has become available since the listing determination. Categories of requested information include—(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; 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.

If you wish to provide information for this 5-year review, you may submit your comments and materials to the Colorado Field Office Supervisor (see ADDRESSES). Our practice is to make comments, including names and home addresses of respondents, available for public review during regular business hours. Respondents may request that we withhold a respondent's identity, as allowable by law. If you wish us to withhold your name or address, you must state this request prominently at the beginning of your comment. However, we will not consider anonymous comments. To the extent consistent with applicable law, we will make all submissions from organizations or businesses, and from individuals identifying themselves as representatives or officials of organizations or businesses, available for public inspection in their entirety. Comments and materials received will be available for public inspection, by appointment, during normal business hours (see ADDRESSES).
