Borneo :Gunung Mulu National Park
Important both for its high biodiversity and its karst character, the Gunung Mulu National Park (52,864 ha), in the state of Sarawak on the island of Borneo, is the most studied tropical karst region in the world. The park contains 17 vegetation zones with about 3,500 species of vascular plants. It is considered one of the richest sites in the world for palms, with 109 species from 20 genera described. The summit of Gunung Mulu, a karst peak 2,377 m high, dominates the park. At least 295 km of explored caves offer an extraordinary spectacle with millions of swiftlets and bats. The Sarawak Chamber, measuring 600 m by 415 m and 80 m high, is the largest known underground chamber in the world.
