Kutai National Park is a superb conservation area in East Kalimantan that represents a lowland tropical rainforest ecosystem. Kutai National Park is rich in biodiversity and stretches from the coast to the lowlands, making this area important for protecting flora and fauna. The Kutai National Park became known in 1914, when a Dutch geologist, H. Witkamp, wrote about the rich forests in the eastern part of the island of Borneo and finally proposed this area as a wild reserve. Until now, this area still survives and is known as the Kutai National Park.
