End Further Info End Preamble Start Supplemental Information


On June 4, 2015, we published a proposed rule (80 FR 31875) to remove the Hualapai Mexican vole from the List of Endangered and Threatened Wildlife in title 50 of the Code of Federal Regulations (50 CFR 17.11(h)). We are proposing this action because the available information indicates the original scientific classification is no longer the appropriate determination for the subspecies, meaning that current data indicate that the original classification may be erroneous. We sought information, data, and comments from the public regarding the proposal for 60 days, ending August 3, 2015.

We are reopening the comment period on that proposed rule for an additional 30 days (see DATES) while we simultaneously issue a notice in local newspapers. We will accept written comments and information during this reopened comment period. In particular, we seek comments concerning the following:

(1) New information concerning the taxonomic classification and conservation status of Hualapai Mexican voles and Mexican voles in general;

(2) New information on the historical and current status, range, distribution, and population size of Hualapai Mexican voles, including the locations of any additional populations; and

(3) New information regarding the life history, ecology, and habitat use of Hualapai Mexican voles.

Please refer to the proposed rule for more information on our proposed action and the specific information we seek.

Before including your address, phone number, email address, or other personal identifying information in your comment, you should be aware that your entire comment—including your personal identifying information—may be made publicly available at any time.
