“Singapore’s fragmented forests are home to a small population of Raffles’ banded langurs, one of the world’s most threatened primates.

Citizen scientists are helping conservationists protect the arboreal species across the island’s densely urbanized landscape.

By collecting long-term and consistent data in known strongholds, volunteers have identified langur food plants and movement corridors, boosting efforts to enrich and reconnect their habitats.”
