Javan rhinos are among the most endangered mammals in the world: They live on one island in Indonesia, in the path of tsunamis. Saving them will ultimately require establishing additional populations.
The Leuser ecosystem in northern Sumatra is home to some of the world's rarest and best-loved animals. Thanks to a new government moratorium on land clearing, conservationists have enjoyed a big win.
Indonesia could manage without its rhino, unlike African countries which rely on safari dollars.
