Conservationist Yap Jo Leen launched the Langur Project Penang after witnessing dusky langurs, an endangered monkey she was studying for her Ph.D. research, getting struck by vehicles on Malaysia’s Penang Island.Since 2019, her group has built three canopy bridges made from repurposed fire hoses to help langurs and other tree-dwelling wildlife safely cross busy roads, with no recorded langur roadkill deaths at the first bridge site since its installation.The project combines wildlife conservation with citizen science and environmental education, training volunteers to track langur movements, collect ecological and social data, and work with local communities to reduce human-wildlife conflict.Yap says the long-term goal is not simply to build more wildlife bridges, but to foster a broader culture of coexistence and community stewardship for urban wildlife across Malaysia.
TANJUNG BUNGAH, Malaysia — When Yap Jo Leen was tracking dusky langurs in the forests of Penang for her master’s degree in 2016, she watched a langur they called Towkay Soh — Hokkien for “lady boss” — get hit by a car while trying to cross a busy coastal road. Dazed, the langur managed to get back on its feet and retreat into a tree while Yap and her colleagues blocked traffic.
