Langur Project Penang

An citizen science driven outreach research project on the ecology, behaviour & road ecology of Dusky Langurs (Trachypithecus obscurus) for the development of a sustainable langur conservation in Penang.

-What We Do-


A study on the ecology, behaviour, and road ecology of Dusky Langurs. Check out the past volunteer and interns share about their experiences as a dusky!

Environmental Education

We believe that co-existence between people and wildlife can be established through environmental education. Get to know more about our outreach program and public engagements.


Forest fragmentation is one major problem leading to the population decline of the arboreal dusky langur. Find out more about the urban canopy bridge as solution to reduce wildlife roadkill incidents.

Mission Statement:

To be the voice of the dusky langurs and wildlife residents in Penang, to serve as a citizen science-based platform for students and the local community, where LPP lead towards promoting coexistence between humans and wildlife through field research, conservation (urban canopy bridge), and environmental education.
