Protecting flagship endangered species in Borneo

The Bornean rainforest is a crucial enclave for endangered wildlife, under threat from habitat loss and poaching. Using their expertise in mapping habitats, researchers at Cardiff's Danau Girang Field Centre (DGFC) determined how the Bornean elephant, Bornean banteng, proboscis monkey and Sunda clouded leopard use fragmented forest in Sabah. This led to new, state-backed conservation measures and investment to protect these four key species.

Funding for forest recovery and replanting

The DGFC's research provided critical evidence that new approaches to forest management were needed to safeguard all four species. Together with Sabah Wildlife Department (the key government authority for wildlife protection), they created State Action Plans outlining key steps to support each species. Their recommendations included:

  • improving landscape connectivity
  • working with NGOs, the palm oil industry and local communities to recover underproductive palm oil plantations and return them to forest suitable for Bornean elephants and other species
  • preventing the loss of any suitable habitat (open grassy and sedge areas and forest shade) for Bornean bantengs and developing and maintaining pastures within the range of existing herds
  • increasing mangrove and riparian forest areas suitable for proboscis monkeys
  • halting loss and degradation of habitats used by Sunda clouded leopards (such as forest canopy cover)

The Sabah Government invested £7 million over a ten-year period to carry out these steps, and began the first phase of reforestation in 2019, planting a million trees on over 4,000 hectares of degraded forest. Meanwhile, the DGFC team is working with the local community to replant forest, along with its partner KOPEL Bhd, an NGO (non-governmental organisation) representing four local villages and supporting sustainable livelihoods.

The Action Plans also serve as a framework for replanting by other NGOs and the government. In 2020, the Rhino and Forest Fund and the Sabah Wildlife Department bought a 65 hectare oil palm plantation to replant. This will reconnect two key areas of protected forest and benefit Bornean elephants and bantengs.

How they did it

The DGFC researchers analysed the spatial ecology of the four endangered animals. Using camera traps, satellite, GPS telemetry tracking and LiDAR technology, as well as drones, they were able to model how each species used the forest. This provided evidence that protecting both mature and degraded forest, as well as replanting trees to make wildlife corridors (allowing animals to move between segments of existing forest) were all fundamental to their survival.

Successful campaigning for sensitive land development

Cardiff’s research into the Bornean elephant’s movements led Professor Goossens, as DGFC Director, to campaign strongly against the planned construction of a bridge over the Sukau river, which would further fragment the elephant’s habitat. This campaign raised the profile of the issue, attracting Sir David Attenborough’s support, and as a result, the bridge was scrapped.

Based on DGFC’s research data, and following advice from Coalition 3H (Humans, Habitats, Highways), an alternative route for the Pan Borneo Highway is now being considered by the Sabah government. The Highway was due to cross mangrove forest reserves which the Cardiff team had identified as the last remaining habitat of the proboscis monkey, as well as forest reserves critical for the Bornean elephant and Sunda clouded leopard. Building the Highway in those areas would have damaged these important habitats and led to a decline in the endangered species.

Key facts

  • Bornean elephants are classified as endangered by the IUCN (International Union for Conservation of Nature) Red List of Threatened Species. It's estimated there are between 1,000-1,600 left in Sabah.
  • The Bornean banteng is a species of wild cattle endemic to Borneo. It's the most endangered large mammal in Sabah, which is believed to be its last stronghold.
  • The Sunda clouded leopard is one of the world’s rarest and least-studied big cats. Sabah is home to 750 individuals.
