Sea turtle nesting beaches face multiple threats including light pollution, human disturbance, sand compaction from vehicles, and predation that affect both adult female welfare during nesting and hatchling survival.
Sea turtle nesting beach protection is one of the clearest examples of direct welfare intervention for wild animals. Nesting females in good-quality beaches complete their nesting cycle with minimal stress; those on disturbed beaches experience harassment, misdirection, and physiological stress during an energetically demanding process. Hatchlings on properly protected beaches reach the ocean with minimal energy expenditure; those on lights-on, vehicle-driven beaches may travel in circles for hours before dying. The interventions that protect nesting welfare — lighting ordinances, vehicle restrictions, and nest protection — are achievable through local policy and volunteer monitoring programs.
