Sea turtle nesting beaches face multiple threats from artificial lighting, beach development, predation, and rising temperatures that endanger both nesting females and hatchlings.
Sea turtle welfare on nesting beaches spans the full spectrum from individual hatchling to population. Disoriented hatchlings face exhaustion, dehydration, and predation during misdirected crawls inland. Nesting females disturbed by lights or beach activity abort nesting attempts, wasting the enormous energetic investment of a nesting migration. Predation of nests eliminates entire clutches of 80-120 developing embryos. Rising sand temperatures that consistently exceed approximately 32C kill embryos within nests or produce turtles with developmental abnormalities. Beach patrol and nest protection programmes are among the highest-impact welfare interventions available for sea turtles — directly preventing deaths at the individual level while protecting population recovery.
