Manatee Behavior and Seasonal Welfare Patterns

Manatee behavior varies dramatically by season, with winter aggregations at warm water refugia creating distinct welfare opportunities and risks.

Key Facts

Florida manatees aggregate at natural warm springs and power plant discharge sites in winter
Crystal River National Wildlife Refuge supports the largest winter aggregation of manatees in the US
Cold stress syndrome occurs when manatees are trapped in cold water below 20C
Warm water aggregations create disease transmission risks for respiratory infections
Climate change is affecting power plant discharge site availability as facilities retire

Welfare Considerations

Manatees dependent on power plant warm water discharge face an emerging welfare crisis as aging coastal plants retire without replacement. Without adequate warm water refugia, cold stress syndrome - which causes immune suppression, skin lesions, and death - becomes more frequent. Wildlife managers have identified natural warm spring systems and created artificial warm water refugia, but the scale of the challenge requires both habitat management and climate adaptation planning. The welfare of individual manatees during cold events depends on rapid rescue and rehabilitation capacity.

What You Can Do

Support Save the Manatee Club's warm water access advocacy and monitoring programs
Donate to manatee rescue operations that respond to cold stress events
Advocate for warming water refugia to be considered in coastal power plant retirement planning
Never disturb manatees in warm water refugia - their use of these areas is thermally necessary
Learn about manatee thermal ecology to understand why warm water access is a welfare issue
