On April 5, 2017, the U.S. Fish and Wildlife Service (Service) issued a final rule in the Federal Register reclassifying the West Indian manatee (Trichechus manatus) from endangered to threatened under the Endangered Species Act. Despite the reclassification, the Federal Register explained that while some significant threats have been reduced or eliminated, there are still a number of threats that remain, such as habitat loss and poaching, and that implementation of recovery actions are needed for the manatee to fully recover.

The reclassification was the result of a 5-year status review by the Service that included a recommendation to reclassify the manatee, and a subsequent petition by the Pacific Legal Foundation requesting the reclassification.
