Welfare of Marine Turtles During Nesting Season Disturbance

Human disturbance on nesting beaches — tourism, lighting, beach furniture, and development — disrupts sea turtle nesting behavior and causes nest abandonment with welfare consequences for nesting females.

Key Facts

False crawls — where turtles come ashore but fail to nest due to disturbance — waste enormous energy in already depleted animals
Artificial lighting on nesting beaches causes females to abort nesting attempts at rates that significantly reduce reproductive success
Beach furniture and umbrellas left overnight physically trap nesting turtles and hatchlings
Turtle-safe red lighting on beaches reduces orientation disruption while allowing human beach use
Volunteer monitoring programs have transformed knowledge of nesting success and disturbance impacts on major nesting beaches

Welfare Considerations

Female sea turtles returning to natal beaches to nest are among the most energy-constrained wild animals on earth. They have traveled hundreds of miles, fasted for weeks, and arrived depleted to undertake the energetically demanding work of nest excavation and egg laying. Human disturbance that causes them to abort nesting attempts and return to the sea — the false crawl — wastes irreplaceable energy at a critical life stage. Beach management for turtle welfare is inexpensive and well-understood; implementation requires only the will to put nesting success above convenience.

What You Can Do

Support turtle-safe beach management through donation and advocacy
Remove beach furniture and fill in holes before dusk during nesting season if you use nesting beaches
Never use white lights on nesting beaches — use red lights or no lights after dark
Participate in or support sea turtle nesting monitoring programs on nesting beaches
