Community ecology of primates in Danum Valley Conservation Area

Report:HANYA, Goro

Date:2008/09/18 - 2008/09/25

I have conducted my project on the community ecology of five species of diurnal primates in Danum Valley Conservation Area since September 2006. My Malaysian assistants continue collecting data sampling while I am not at the study site. Since the beginning of the project, I have conducted primate census, orangutan nest census and fallen fruit census along a trail of 9. 9 km in length. Since December 2006, I have conducted behavioral observation of one group of red leaf monkeys. I started to observe other primates in May 2007. This time, I followed red leaf monkeys for 19 hours in two days and orangutans for 8 hours in one day. Every 10 minutes, I recorded the activity (feeding, moving, grooming and resting), the height of the animal and the height of the tree where animals are staying for all the visible individuals. When they are eating, I collected food samples and identified species. On the way back from the study site, I visited the Institute for Tropical Biology and Conservation, University Malaysia Sabah and kept plant samples, in order to receive approval letter to bring the samples out of Malaysia.
