Sea turtle nesting beaches are critical habitats where turtles are highly vulnerable to human disturbance. Managing beach tourism and development to protect nesting females and hatchlings has major welfare and conservation implications.
Sea turtle nesting beach welfare encompasses the acute welfare of individual nesting females and hatchlings as well as long-term population welfare implications of habitat quality. Nesting is physiologically demanding for females, who may fast during the nesting season while making multiple nesting attempts. Human disturbances that abort nesting attempts impose energy costs and reduce reproductive success for individuals that may only return to nest every 2-5 years. Beach lighting creates disorientation welfare harms for both adult females during nesting approaches and hatchlings during their critical emergence and ocean-finding behavior: hatchlings moving toward artificial light rather than the ocean die from exhaustion, predation, or dehydration before reaching water. Beach development that compacts sand, reduces slope, and introduces debris obstacles impairs the physical welfare of heavy turtles navigating nesting corridors. The combination of trained turtle guide programs that mediate tourist access, beach lighting ordinances that require wildlife-safe lights or shutters during nesting season, and nesting corridor protection from development represents the integrated management approach that achieves both welfare and conservation outcomes.
