Marine turtle nesting beaches face multiple human-caused disturbances that reduce reproductive success and directly harm adult turtles and their offspring.
Marine turtles experience direct welfare harm from nesting beach disturbance. Female turtles that encounter disturbance while seeking nesting sites may abort nesting attempts, sometimes repeatedly, depleting energy reserves. Disoriented hatchlings that follow artificial lights instead of the sea exhaust themselves and die from dehydration or predation. Nest incubation temperature, affected by nest shading and trampling, determines both hatching success and offspring sex ratio. The combination of these pressures on long-lived species with late reproductive maturity makes population recovery slow even when adult mortality is reduced. Beach management practices including lighting ordinances, vehicle access restrictions and nest marking substantially improve reproductive success.
