Head-start programs have significantly increased juvenile survival in several crocodilian species.
Natural predation, habitat instability, and human disturbance combine to produce extremely high juvenile mortality rates in wild gharials. Eggs and hatchlings face threats from birds, reptiles, mammals, and flooding events. Even after reaching water, small juveniles are vulnerable to larger predators. Survival probabilities increase sharply with size. Conservation head-start programs aim to reduce early losses by raising young in protected environments. Without such intervention, recruitment may be insufficient to offset adult mortality. The life cycle is front-loaded with risk.

High early mortality evolved under conditions where abundant habitat allowed enough survivors to reach adulthood. When habitat shrinks, natural attrition becomes unsustainable. Small changes in early survival rates can dramatically influence long-term population trajectories. Juvenile protection is therefore a strategic conservation focus.
Population recovery depends on shifting survival curves during the first year of life. Artificial incubation and controlled rearing alter demographic mathematics. However, true resilience requires restoring natural survival conditions. Without addressing habitat quality, intervention becomes perpetual necessity.
