Marine turtle nesting beaches face increasing threats from coastal development, light pollution, and human disturbance, with direct welfare consequences for nesting females and emerging hatchlings.
Nesting beach protection for marine turtles addresses both acute welfare harms and long-term population survival. For individual turtles, disturbance during nesting is highly stressful, causing hormonal stress responses and sometimes abandonment of valuable energy stores invested in egg production. For hatchlings, disorientation by light leads to exhaustion, dehydration, and predation mortality. The welfare harms are preventable with relatively simple interventions: lighting restrictions, beach access controls during nesting season, and public education. When properly protected, nesting beaches produce generation after generation of hatchlings with minimal human-caused welfare harm.
