Sea turtle nesting beaches are critical welfare hotspots where human disturbance, artificial lighting, and climate change threaten both nesting females and hatchlings. Conservation management at these sites has direct welfare benefits for millions of individual turtles.
The welfare of nesting females is directly compromised by human disturbance. Turtles interrupted mid-nesting abort clutches and return to sea still gravid — a physiologically costly experience that may force re-nesting attempts under sub-optimal conditions. Repeated disturbance can cause nesting failure entirely, with females abandoning beach sections. Hatchlings disoriented by artificial light travel vast distances in the wrong direction, becoming dehydrated, exhausted, and vulnerable to predation before reaching the sea — a prolonged negative welfare experience for millions of individuals annually. Red-spectrum lighting near beaches is invisible to most sea turtle species and represents a practical coexistence solution allowing coastal communities to maintain lighting for human use while eliminating disorientation.
