Workers install a video trap as part of the rhino-monitoring project, which operates in conjunction with several nonprofits and local communities.
Organizers hope that including local people in the monitoring effort will help them protect the species from poaching, oversee the remaining animals, and establish a new population of rhinos via relocation.
"Fifty years of conservation experience has taught us that saving Javan rhinos is possible through population management and proper protection," WWF's Long said.
"We've done it before—helping rhino populations rebound in Africa and South Asia—and we can do it again in Indonesia."
