Kinabatangan River
Sabah
The Kinabatangan River, located in eastern Sabah, Malaysia, is the country's second longest river, stretching approximately 560 kilometers from the mountains in southwest Sabah to the Sulu Sea near Sandakan. This river basin is renowned for its exceptional biodiversity, encompassing diverse ecosystems such as limestone caves at Gomantong Hill, dryland dipterocarp forests, freshwater swamp forests, oxbow lakes, and coastal mangrove swamps. It supports a remarkable variety of wildlife including Bornean orangutans, proboscis monkeys, Borneo elephants, Sunda clouded leopards, and numerous hornbill species. The river's lower floodplain has been designated a protected wildlife sanctuary, safeguarding habitats critical for many endemic and endangered species. The surrounding communities, including the Orang Sungai with mixed ancestry, have historically depended on the river for livelihoods, fishing, and trade. Despite pressures from logging and agriculture, conservation efforts since the late 20th century have helped preserve much of the natural environment, making the Kinabatangan River a key destination for eco-tourism and wildlife observation in Borneo.
