The Javan rhino (Rhinoceros sondaicus) is the rarest rhino in the world, and it takes a dedicated and coordinated effort to ensure the survival of this elusive and majestic species. The task is much more than a day job. Rangers and local community members spend weeks at a time in the forest, patrolling, monitoring, and protecting the rhinos’ remaining habitat in Ujung Kulon National Park, Indonesia.
