One of the biggest reasons for sun bear remains so little known is the lack of biological studies on this species. Until now, there are only 3 ecological studies that involved trapping and radio-collaring of wild sun bear in the world. One of them is my study base in Danum Valley Field Center and Ulu Segama Forest Reserve, Sabah, Malaysia Borneo. I did my Master of Science (MSc) project on studying the ecology of sun bear from 1998 – 2000, and then continued the study, by looking at the effects of logging on sun bear and bearded pigs for my doctorate degree.
Here are lists of publications with PDF from my M.Sc. studies:
- The Ecology of Malayan Sun Bears (Helarctos malayanus) in the Lowland Tropical Rainforest of Sabah, Malaysian Borneo. 153 pp.
- Wong, S.T., C. Servheen, L. Ambu, and a. Norhayati. 2005. Impacts of fruit production cycles on Malayan sun bears and bearded pigs in lowland tropical forest of Sabah, Malaysian Borneo. Journal of Tropical Ecology 21:627-639. 13pp.
- Wong, S.T., C.W. Servheen, and L. Ambu. 2004. Home range, movement and activity patterns, and bedding sites of Malayan sun bears Helarctos malayanus in the Rainforest of Borneo. Biological Conservation 119:169-181.

Other publications, reports and articles from my sun bear works:
- Wong, S.T. 2006. The status of Malayan sun bear in Malaysia. Pp 66-72 in Japan Bear Network (compiler). 2006. Understanding Asian bears to secure their future. Japan Bear Network, Ibakari, Japan 145 pp.
- Wong, S.T and C. Servheen. 2007. Sun Bear and Bearded Pig Research and Conservation Project: 4th Progress Report. 16pp.
- The Emerging Wildlife Conservation Leaders, Wong S.T. & Gabriella Fredriksson. 2006. Sun Bear Adventure Journals. EWCL. 34 pp.
Currently Gabriella is assisting with the redesign of forest and conservation management for the province of Aceh (Sumatra), in a team established by the Governor of Aceh. Aceh with 3 million ha of contiguous forest has probably the most viable habitat and populations of sun bears and many other threatened species in Indonesia (orangutans, elephants and tigers).
I found this newspaper article written some 10 years ago when she first attempted to reintroduce 5 adult sun bears into the wild: “In Borneo's Fading Jungles, a Grim Tale of Wildlife.”
