Sea turtle nesting beaches are critical habitat requiring protection from artificial lighting, vehicle traffic, and human disturbance to ensure successful reproduction and hatchling welfare.
Sea turtle nesting beach welfare encompasses the welfare of nesting adult females, eggs, and emerging hatchlings. Female turtles that abandon nests due to disturbance experience physiological stress and reproductive failure, potentially retaining eggs that cause health complications. Hatchlings that misnavigate due to light pollution face exhaustion, predation, and death as they travel inland rather than to the sea. Nest protection programs that screen nests, manage artificial lighting, and control feral predators can dramatically improve hatching success. Climate change poses an emerging threat through beach temperature increase affecting incubation conditions and sex determination — beaches that produce almost exclusively female hatchlings under current warming trajectories will eventually reduce reproductive viability.
