The bill requires a study to identify alternative habitat for manatees affected by industrial site decommissioning in Florida. It mandates assessing natural warm water locations and constructing artificial warm water refugia. The Secretary must develop methods for creating refugia and coordinate with the Florida Fish and Wildlife Conservation Commission. A publicly available report on the study's results is due within 180 days. The bill defines "manatee" as a species of trichechus manatus and "Secretary" as the Secretary of the Interior, acting through the Director of the United States Fish and Wildlife Service.
