Who We Are

Founded in January 2016, the Langur Project Penang (LPP) is a community science-based outreach and conservation project in Malaysia. In collaboration with governmental bodies, educational institutions, and Non-Governmental Organizations (NGO) in Malaysia. LPP aims to foster Coexistence among humans and urban wildlife through citizen science-based fieldwork capacity building, environmental education, and conservation efforts.

LPP is founded by Dr. Jo Leen Yap, a wildlife researcher, environmental educator, and certified Malaysian Regional Nature Guide. studying the ecology and behaviour of Dusky Langurs (Trachypithecus obscurus) in Penang. Jo Leen has the vision to further bridge the gap between primate conservation and community engagement in Malaysia. With her enthusiasm, and positive, creative mindset, Jo Leen is always on-the-go, thinking of the dusky langurs, for her team members, in order to sustain LPP as a long-term community science platform in Malaysia.
