We, the U.S. Fish and Wildlife Service (Service or USFWS), announce a 90-day finding on a petition to reclassify the West Indian manatee (Trichechus manatus) as threatened under the Endangered Species Act of 1973, as amended (Act). Based on our review, we find that the petition presents substantial scientific or commercial information indicating that the petitioned action may be warranted. Therefore with the publication of this notice, we are initiating a review of the status of the species to determine if reclassification is warranted. Section 4(c)(2)(A) of the Act also requires a status review of listed species at least once every 5 years. We are, therefore, electing to conduct the 5-year review simultaneously with the status review. To ensure that this status review is comprehensive, we are requesting scientific and commercial data and other information regarding the West Indian manatee including its subspecies the Florida manatee and Antillean manatee. Based on the status review, we will issue a 12-month finding on the petition, which will address whether the petitioned action is warranted, as provided in section 4(b)(3)(B) of the Act.
