A graceful black monkey edges across a swaying red rope bridge strung over a busy residential road in Malaysia's Penang, watched by local conservationists who carefully record her movements.
For Malaysia's endangered dusky langurs, recognizable by the "masks" of white fur that ring their eyes, survival increasingly depends on such man-made crossings and the work of "citizen scientists."
A fragmented habitat, conflict with local communities and poaching have all pushed the species to endangered status.
But the Langur Project Penang (LPP) conservation group hopes that low-tech engineering and high-tech community engagement can help protect the species, also known as the dusky leaf monkey.
Key to their efforts is helping the monkeys navigate fragmented habitat crisscrossed by busy roads where the animals are often killed.
