Wild Leatherback Turtle Nesting Welfare

Leatherback sea turtles undertake epic migrations and face welfare challenges at nesting beaches from artificial lighting, beach traffic, and climate-driven temperature changes.

Key Facts

Leatherbacks are the largest of all sea turtles, weighing up to 900kg
They migrate from tropical nesting beaches to cold-water feeding grounds in the North Atlantic
Artificial beachfront lighting disorients hatchlings that navigate toward the sea by moonlight
Climate change is shifting the sex ratio of sea turtle populations toward predominantly female
Leatherbacks are listed as Vulnerable globally but some subpopulations are Critically Endangered

Welfare Considerations

Hatchlings disoriented by artificial lighting wander toward roads and buildings rather than the sea, dying from exhaustion, dehydration, or vehicle strikes. Nesting females are disturbed by beach traffic and lighting, causing nest abandonment or nest site shifts to less suitable locations. Warmer sand temperatures from climate change affect embryo development and produce almost exclusively female hatchlings. Each welfare intervention at nesting beaches has multiplied impact given sea turtle longevity and low reproductive rates.

What You Can Do

Support beach lighting ordinances that require turtle-friendly fixtures during nesting season
Participate in or donate to sea turtle nest monitoring programmes
Reduce beachside lighting during turtle nesting season (May-October in Florida)
Support marine protected areas covering leatherback feeding grounds in cold waters
Advocate for plastic pollution reduction as leatherbacks frequently ingest plastic jellyfish
