Kulamba Wildlife Reserve
Asia > Malaysia > Kulamba Wildlife Reserve
Summary
- Northeast Bornean orangutans (Pongo pygmaeus morio) are present in Kulamba Wildlife Reserve.
- It has been estimated that 361 (CI: 223–488) individuals occur in the site.
- The orangutan population trend is decreasing.
- The site has a total size of 387 km².
- Key threats to orangutans are habitat fragmentation mainly due to land conversion for agriculture and plantations, and hunting.
- Conservation activities are not documented.
Site characteristics
Kulamba was gazetted in 1984 as a Wildlife Reserve. The reserve is located in Malaysia, Borneo, in the eastern part of Sabah. The site is mostly swampy and flat, with isolated, locally steep hills measuring up to 70 m above sea level . The reserve's contiguity with the Kinabatangan floodplains provides an important habitat for several resident and migrant globally threatened waterbirds (BirdLife International 2021). In addition to Bornean orangutans, banteng, or tembandau (a species of wild cattle) also inhabits the site, along with proboscis monkeys, marble cats, Bornean gibbons, long-tailed macaques, and Malayan sun bears (BirdLife International 2021).

Ape status
The orangutan population in Kulamba declined by 30% in 15 years, between 2002 and 2017 (Simon, Davis & Ancrenaz 2019).

Threats
Oil palm, coconut, rubber and rattan plantations are being developed at a fast rate to the south and west of the reserve (BirdLife International 2021). Habitat fragmentation is a major threat in the region where the site is found. In 2013 a palm oil plantation was planned adjacent to the reserve (Hance 2013).
