A conservation biologist specializing in reptiles, Shahriar Caesar Rahman won the nature guardian award for his work to preserve Asia’s largest tortoise in a remote corner of Bangladesh. In 2011, Caesar began exploring the Chittagong Hills, one of the least explored but most bio-diverse areas on the planet. His team discovered the wild Asian giant tortoise, previously thought to be extinct, and a new species of forest turtle.
