An outreach research project on the ecology, behaviour and road ecology of Trachypithecus obscurus for development of sustainable langur conservation in Penang. The study started from habituating, following the langur study troops consistently, collecting data on their activities, diet, home range and habitat quality. This information enables us to compare the impact of anthropogenic environment toward the movement and behaviour of Dusky Langurs in Penang, then coming out with conservation initiatives to mitigate the impact of human-altered landscape habitat.
