Nesting female sea turtles and their hatchlings face significant welfare threats from artificial lighting, beachfront development, and rising sand temperatures on critical breeding beaches.
Nesting beach welfare encompasses the experience of nesting females navigating human-modified coastlines and hatchlings attempting to reach the sea. Nesting turtles that encounter beach furniture, beach bars, and crowds during the night emerge and immediately return to sea without nesting — a failed nesting attempt after an energetically costly journey. Repeated failed nesting attempts cause physiological stress and reproductive failure. Hatchlings drawn by artificial light inland instead of seaward become exhausted, are predated, and dehydrate rapidly in the sun if not found and redirected. Temperature-driven sex ratio skewing creates longer-term population welfare concerns — male-sparse populations have reduced reproductive success. Beach management programs including light ordinances, furniture removal requirements, and volunteer monitoring networks significantly reduce these harms.
