Main image

The Lamandau River flows through Central Kalimantan on the island of Borneo and drains a basin of lowland tropical forest. It is a significant river for local communities, wildlife habitat and access into interior forest areas.

Sections of the river and its surrounding forest are important for biodiversity and have been the focus of orangutan conservation and rehabilitation efforts in the region. The river corridor is used for small-boat transport and as an access route to settlements and conservation sites.

The river runs through Central Kalimantan province and connects forested inland areas with larger river systems and downstream waterways in Borneo’s lowlands.

  • Conservation and transport: River transport is important locally and the river basin contains areas of lowland tropical forest that are important for wildlife including orangutans.
