In Malaysia’s Penang state, conservationists and residents are collaborating to reduce conflict between humans and endangered dusky langurs displaced by urban development and habitat loss.

The Langur Project Penang built a canopy bridge to help langurs safely cross a busy road and access more habitat, reducing time spent in residential areas and lowering complaints from residents.

Malaysia’s wildlife agency receives thousands of wildlife complaints annually, and often responds with trapping, relocation or culling; but conservationists argue education and coexistence measures can be more sustainable responses to increasing human-wildlife encounters.

The project’s success has depended heavily on local support and citizen scientists, with some residents gradually shifting from frustration toward compassion and acceptance of living alongside wildlife.

TANJUNG BUNGAH, Malaysia — The 50-year-old mango tree growing through Tan Soo Siah’s second-story terrace is a favorite stopping place for the family of endangered monkeys that has taken up residence in a small park near his home in Malaysia’s Penang state.
