This project is focused on management and protection of the Sungai Wain Protection Forest (SWPF) in East Kalimantan, Indonesian Borneo. This is a relatively small (ca 10,000 ha) but vitally important forest area as it supplies about 25% of the freshwater needs of Balikpapan [ca 700.000 inhabitants, the 4th largest city on Borneo), including all fresh water for the Pertamina oil refinery. It is currently the last example of primary lowland rainforest in the wider area. Sungai Wain is home most Bornean lowland rainforest species, including many endemics (all 5 of Borneo\’s cat species, including the endemic Bay Cat; all 8 hornbill species, including the Critically Endangered Helmeted Hornbill; 9 primate species including a population of orangutans reintroduced in the 1990\’s and viable populations of 4 endemic primate species [Proboscis monkeys, Mueller\’s Gibbons, Red leaf monkeys, White-fronted leaf monkey; Sun bears [the first ever wild population that was studied]; rare endemic birds such as the Bornean ground cuckoo and Peacock pheasant). In addition, more than 30 tree species found in this lowland forest are listed as Critically Endangered. Recently 1,385 ha of forest in an adjacent watershed was added as an extension to the SWPF and one of our aims is to further expand the protected area network to reconnect SWPF to other forest patches through corridor development.
Threats to the SWPF primarily consist of forest fires during periods of drought, encroachment and deforestation by immigrants and increased poaching pressure of mammals and birds. Pro Natura focuses on strengthening management of this unique lowland forest through 3 key components: protecting the forest and its fauna from poaching, logging, encroachment and prevention of forest fires through active community patrols; monitoring health of key species populations and regeneration of burned over forest; raising conservation support through awareness and education.
