Sea turtle nesting beaches are critical welfare environments where female turtles experience light pollution, temperature extremes, and human disturbance during the vulnerable nesting process.
Sea turtle nesting beach welfare extends to the entire nesting process: the approach from the ocean, the exhausting excavation of the nest cavity, egg laying, covering, and return to the sea. Artificial light disorientation causes females to wander away from the ocean, sometimes dying from dehydration or vehicle strikes. Nest abandonment from disturbance wastes enormous reproductive energy after a long migration. Temperature changes from climate warming alter sex ratios — extreme feminization of hatchling populations threatens future reproductive viability. Protecting nesting beaches through light ordinances, vehicle restrictions, and nest monitoring protects individual welfare and population recovery simultaneously.
