Sea turtle nesting beaches are critical for species survival and individual welfare. Human disturbance, light pollution, and predation cause significant suffering to nesting females and hatchlings.
Nesting sea turtles experience multiple welfare harms from human activity. Females disturbed during nesting attempts may abort and return to sea without successfully laying — an energetically costly failed reproductive effort after a long migration. Disoriented hatchlings travelling inland die from dehydration, exhaustion, and predation before reaching the sea. Beach vehicles crush nests and hatchlings emerging at night. Climate-driven sand temperature increases are feminising hatchling populations and creating thermal stress that reduces hatching success. Predator removal around nesting beaches — while ecologically controversial — dramatically reduces predation mortality for both eggs and hatchlings. Nest protection programmes that cage at-risk nests and monitor hatch success have proven effective at recovering local populations.
