Gibbons are known to tolerate some disturbance and persist in secondary/degraded forests, though their densities tend to be higher in less-disturbed forests. There are previous and on-going researches of various species of gibbons being done in Thailand and Sumatra, primarily focusing on their diet, behaviour, abundance and distribution with regards to forest types. However, similar studies done on gibbons throughout Malaysia is lacking, since the last publication about gibbons in Malaysia was in 1980s. Therefore, the current population estimate and distribution range of gibbons in Malaysia is unknown.
The goal of this study is to contribute valuable data about agile gibbon (Hylobates agilis) abundance, density, distribution and responses to habitat disturbance to inform the development of effective conservation programs for gibbons and their habitats. I plan to collect field data for approximately 6 months, with two months allocated for each forest type: unlogged primary forest, previously-logged forest and recently-logged forest. In each forest type, I plan to conduct acoustic surveys at three sites in each habitat type. In each sites, I will establish three listening posts and 10 vegetation “speed plots”. Depending on the forest cover and the terrain, the area sampled in each listening area should cover approximately 4 km2. On each sampling trip, my research assistants and I will collect both acoustic and vegetation data from one of the nine listening areas.
At the conclusion of the study, we will collaborate with Malaysian wildlife authorities to develop a feasible action plan for protecting viable populations of gibbons in both protected and unprotected forests. Thus, more evidence is needed to support the idea of including forest reserve and other unprotected areas into the protection plan, before the continuous destruction and degradation of the habitat decimate the gibbons’ existence in Malaysia. With sufficient data and action plan, some of the unprotected areas, Ulu Muda Forest Reserve for example, stands a chance to become a totally-protected state park.
This study will also be educating the general public to appreciate the significance of gibbons towards the forest and vice versa, and be compelled to protect nature and practice sustainability. The project will also raise awareness with regard to the illegal pet trade, which gibbons regularly suffer. Outreach programs will be conducted for students from various local schools in Penang and Kedah state. Games, role-playing and story-telling will be used to convey the message. Pre- and post-program questionnaires will be conducted to evaluate the change in student’s perception on gibbon conservation issues.
