USFWS proposes to list the two subspecies of the West Indian manatee, the Florida manatee (Trichechus manatus latirostris) and the Antillean manatee (Trichechus manatus manatus), under the ESA. They have conducted status reviews for the two subspecies, and, as a result, they are proposing to list the Florida manatee as a threatened species with protective regulations under section 4(d) of the Act ("4(d) rule"), and the Antillean manatee as an endangered species, under the Act. These two listings would replace the current threatened species listing of the West Indian manatee (Trichechus manatus). This determination also serves as their 12-month findings on two petitions and as their completed 5-year review of the West Indian manatee. If finalized this rule as proposed would remove the West Indian manatee from the Federal List of Endangered and Threatened Wildlife (List), add the Florida manatee and Antillean manatee to the List, and extend the Act's protections to the Florida manatee and Antillean manatee. They will accept comments received or postmarked on or before 17 March 2025.
