The area has a high biodiversity potential in terms of breeding and migratory bird species and also hosts the symbol species of East Kalimantan, the critically endangered Irrawaddy Dolphin (Orcaella brevirostris), who lives in fresh, brackish and salt water.
Habitat protection requires the establishment of community supported and law enforced zones of critical wetlands, lakes and river habitat in the MMA. In this respect, a more holistic approach is needed to match the overlapping interests in the usage of the area by the different stakeholders such as fishermen, farmers, government, mining companies, etc..
Protection of the Irrawaddy Dolphin population is already pursued since the year 2000 with the help of several supporters and is mostly focused on increasing awareness of schoolchildren and fishermen. One task is the direct patrols in major dolphin areas to relocate dangerously placed nets and check for entangled dolphins.
Other species inhabiting the area are endangered mammals such as Proboscis Monkeys (Nasalis larvatus), wild Banteng (Bos javanicus) and Crocodiles (Crocodylus siamensis and Tomistoma schlegeli). Required Measures:
