Florida manatees, despite their shape and appearance, do not have much blubber or fat, therefore manatees are dependent on external sources of heat. When temperatures begin to cool off, manatees begin their seasonal migration to warm-water refuges. Broward County is home to two warm-water refuges formed from the outflow of warm water at the FPL Lauderdale and Port Everglades Power Plants. Broward County can be the winter home for 20+% of Florida's manatee population. To ensure the protection of our beloved manatees, Broward County has a Manatee Protection Plan.​​
