This chicken-sized bird, found only on the island of Sulawesi, buries its eggs in geothermally heated sand or sun-warmed soil and walks away. Weeks later, fully feathered chicks dig themselves out and immediately fend for themselves -- no parental guidance, no nest, no fuss. Rawa Aopa Watumohai National Park, sprawling across 1,050 square kilometers of Southeast Sulawesi, is one of the last strongholds of this remarkable bird. But the maleo is just the opening act. Beneath the park's canopy and within its vast swamps live creatures so unusual that early European naturalists questioned whether they belonged to the animal kingdom at all.

The anoa, which lives in Rawa Aopa Watumohai, looks like a water buffalo that someone shrank to the size of a large dog. Both species of this end...

When the Indonesian government declared the park in 1989, it drew boundaries around land that the Moronene people had inhabited for generations. The Moronene are an indigenous group with deep ties to the forests and swamp...

Sulawesi's Hidden Wetland: Rawa Aopa Watumohai: 323 Species and Counting

The park's botanical inventory lists 323 plant species, a number that almost certainly understates the true count given how little of the park has been systematically surveyed. The lontar palm, Borassus flabellifer, rises above the savanna in distinctive fan-shaped crowns. Brugui...
