Five-year Status Review of the Perdido Key Beach Mouse

About the Document

Title:  Five-year Status Review of the Perdido Key beach mouse (Peromyscus polionotus trisyllepsis)


The U.S. Fish and Wildlife Service (Service) is conducting a 5-year status review of the federally listed, endangered Perdido Key beach mouse under section 4 of the Endangered Species Act of 1973, as amended (Act).  The purpose of reviews conducted under this section of the Act is to ensure that the classification of species as threatened or endangered on the List of Endangered and Threatened Wildlife and Plants (50 CFR 17.11 and 17.12) is accurate.  A 5-year review is an assessment of the best scientific and commercial data available at the time of the review.  On the basis of such reviews, we 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 only considered if such 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.

About the Peer Review Process

Type of Review:  Influential

Date of Peer Review:  Peer review will occur between May 2007 and August 2007.

Estimated Dissemination Date of the Final 5-year Review Document: September 2007.

Process:  The Service will conduct external peer review of this document through electronic letters sent to three or more independent scientific reviewers with expertise in beach mouse biology, population genetics, conservation biology, and coastal resource management.

The Service will make formal requests for peer review from the Florida Fish and Wildlife Conservation Commission, Florida Wildlife Research Institute, Florida Department of Environmental Protection, and the University of Central Florida.  Peer review of the scientific information used in our analysis of the status of this beach mouse and the validity of the data will be requested, but peer reviewers will not be asked to provide recommendations on the legal status of the species.

The Service will use the information received from the peer review, as appropriate, in the conclusions and recommendations for the 5-year review of the Perdido Key beach mouse.

About Public Participation

Public comments on the 5 year review for the Perdido Key beach mouse were sought with a Federal Register announcement on September 27, 2006 (71 FR 56545), and the distribution by mail and press release of this announcement to interested parties.

The Service will post a notice on its website of the recommendation resulting from the 5-year review of the Perdido Key beach mouse, including a summary of the results of the peer review process.  If this 5-year review results in a recommendation to change the status of the beach mouse, additional public review and comment will be sought within the proposed rulemaking process.

This peer review plan is made available on this website to allow the public to monitor our compliance with the Office of Management and Budget’s Final Information Quality Bulletin for Peer Review.
