Welfare of Loggerhead Sea Turtles During Nesting

Loggerhead sea turtles return to their natal beaches to nest, and human activity during this vulnerable time directly impacts their welfare and reproductive success.

Key Facts

Female loggerheads return to the exact beach where they hatched to nest
Light pollution from coastal development disorients nesting females and hatchlings
A single female may nest 4-7 times per season, crawling ashore to lay each clutch
Hatchlings navigate to the ocean using the brightest horizon - normally the sea
Loggerhead sea turtles are threatened with an estimated global population under 50,000 females

Welfare Considerations

Nesting loggerheads experience welfare stress from beach lighting, human presence, and coastal development. Disoriented hatchlings entering roads or heading inland die from dehydration or predation. Nesting females disturbed by beachgoers may abort nesting attempts, wasting enormous energy from the ocean migration. Beach driving crushes nests and hatchlings. Climate change is skewing the sex ratio of hatchlings by warming sand beyond the temperature producing equal sex ratios.

What You Can Do

Turn off or shield beach lighting during sea turtle nesting season
Stay away from nesting turtles and hatchling emergence events
Support sea turtle monitoring programs with volunteer hours or donations
Advocate for beach lighting ordinances in coastal communities near nesting habitat
